The purpose of the study was to determine the effects of static and dynamic stretching protocols within general and activity specific warm-ups. Nine male and ten female subjects were tested under four warm-up conditions including a 1) general aerobic warm-up with static stretching, 2) general aerobic warm-up with dynamic stretching, 3) general and specific warm-up with static stretching and 4) general and specific warm-up with dynamic stretching. Following all conditions, subjects were tested for movement time (kicking movement of leg over 0.5 m distance), countermovement jump height, sit and reach flexibility and 6 repetitions of 20 metre sprints. Results indicated that when a sport specific warm-up was included, there was an 0.94% improvement (p = 0.0013) in 20 meter sprint time with both the dynamic and static stretch groups. No such difference in sprint performance between dynamic and static stretch groups existed in the absence of the sport specific warm-up. The static stretch ...

There are very few studies that had a sample size sufficient to explore the association between factors related to low back pain in a representative sample of the Iranian population. Objective. To examine the relationship between sociodemographic factors, smoking, obesity, and low back pain in Iranian people. Methods. We used Iranian adults respondents (n = 25307) from the National Health Survey. Adjusted odds ratios and 95% confidence intervals were estimated by using logistic regression. Results. The prevalence of low back pain was found in 29.3% of the studied sample. High age, female sex, being married, obesity, low-economic index, being smoker, in a rural residence, and low educational attainment, all increased the odds of low back pain. Conclusions. Our findings add to the evidence on the importance of obesity in relation to low back pain. These results can be used as a basis to reinforce health programs to prevent obesity.

DIFFERENT INDIRECT RESTORATIONS TO REPLACE A SINGLE MISSING TOOTH IN THE POSTERIOR REGION ARE AVAILABLE IN DENTISTRY: traditional full-coverage fixed dental prostheses (FDPs), implant-supported crowns (ISC), and inlay-retained FDPs (IRFDP). Resin bonded FDPs represent a minimally invasive procedure; preexisting fillings can minimize tooth structure removal and give retention to the IRFDP, transforming it into an ultraconservative option. New high strength zirconia ceramics, with their stiffness and high mechanical properties, could be considered a right choice for an IRFDP rehabilitation. The case report presented describes an IRFDP treatment using a CAD/CAM monolithic zirconia IRFDP; clinical and laboratory steps are illustrated, according to the most recent scientific protocols. Adhesive procedures are focused on the Y-TZP and tooth substrate conditioning methods. Nice esthetic and functional integration of indirect restoration at two-year follow-up confirmed the success of this c...

It is postulated that ritalin may adversely affect sleep, appetite, weight and growth of some children with ADHD. Therefore, we aimed to evaluate melatonin supplementation effects on dietary intake, growth and development of children with ADHD treated with ritalin through circadian cycle modification and appetite mechanisms. After obtaining consent from parents, 50 children aged 7-12 with combined form of AD/HD were randomly divided into two groups based on gender blocks: one received melatonin (3 or 6 mg based on weight) combined with ritalin (1mg/kg) and the other took placebo combined with ritalin (1mg/kg) in a double blind randomized clinical trial. Three-day food record, and standard weight and height of children were evaluated prior to the treatment and 8 weeks after the treatment. Children's appetite and sleep were evaluated in weeks 0, 2, 4 and 8. Hypotheses were then analyzed using SPSS17. Paired sample t-test showed significant changes in sleep latency (23.15±15.25 vs....

The research carried out for evaluation of dietary fibre successfully concludes the quantity and its consumption on a daily basis in a diet.

Neden eskisi gibi doğmuyor eskisi gibi ölmüyoruz?
Hayat ve ölüm iki kadim mesele. Ama “Sonsuza dek yaşayabilir miyiz?” sorusunun çok modern bir tınısı var. Çünkü tıp teknolojisinin yeni icatları, bu sorudaki ümidi besliyor. Hayata ve ölüme dair anlayışımız da değişiyor. Artık “ölme hakkı”ndan, “yaşama hakkı”ndan bahsediyoruz. Halbuki ölmek ya da yaşamak bir kaderdir, bir kaçınılmazlıktır. Bütün kadim anlayışlarda bu böyledir. Günümüzde biyoteknoloji hayatın ve ölümün sınırlarında geziniyor. Bu kaçınılmazlıkları aşma hırsıyla. O yüzden hem “ölümde iyi”yi (ötenazi) hem de “doğumda iyi”yi (öjenik) tartışıyoruz.
On dokuzuncu yüzyılda evrimci biyoloji, insan-hayvan arasındaki farkı ortadan kaldırmıştı. Günümüzdeyse biyo-teknik ve gen mühendisliği makine-insan arasındaki sınırı belirsiz hale getirdi. Biyonikler, yapay zeka, genetik kopyalama gibi metotlar nedeniyle artık insanın sınırları tartışmalı hale geldi.
Eğer insanın bir kutsiyeti ve doğası yoksa, onu biteviye değiştirmemize, yapay organlarla takviye etmemize, embriyoya müdahale ederek üstün nitelikli insan ya da insan-hayvan-makine arası bir varlık inşa etmemize ne engel olabilir?
Bilim kendi amacını tayin edebilir mi? “Bilimsel” tavır, ölü bedenlere ya da embriyolara sadece birer hücre yığınıymışçasına muamele edilmesini meşrulaştırabilir mi?
Bu kitap, kader ile tasarım arasında salınan “yeni insan”ı bu sorular eşliğinde tartışmaya açıyor.

Luego del políptico de La comunidad de los espectros, un nuevo comienzo se torna necesario. Un giro en el filosofar atento al espesor metafísico de la subversión epocal en curso en todo el orbe. Esa misma crisis revela ahora como insuficientes los métodos más osados de las Humanidades del siglo XX. Un punto de partida: el relato acerca de un supuesto proceso judicial por vampirismo acaecido en un remoto cantón de Hungría a principios del siglo XVIII.
Con el discurrir de las hipótesis aquí propuestas, las relaciones con la licantropía se volverán centrales y ambos fenómenos deberán ser objeto de una minuciosa ultra-historia que acompaña al lector hasta los tiempos paleolíticos del culto de la Gran Madre. Pero esto es sólo el comienzo de un viaje metafísico que, bajo las formas de la sangre, el sacrificio y la metamorfosis, nos conduce hasta el origen mismo de la vida-muerte sobre la Tierra como estación necesaria para una meditación sobre el futuro cosmológico de los seres hablantes. El Vampiro y el Hombre lobo son las figuras filosófico-conceptuales que, una vez desentrañadas, nos muestran la vía regia hacia una forma completamente nueva de rehabilitación del pensamiento especulativo bajo la forma de una “ontología analéptica”.
Desde los inmemoriales rituales del sacrificio antiguo, hasta la teología política inversa del vampirismo, pasando por una inédita filosofía de los virus, se delinea ante nuestros ojos el subsuelo a partir del cual se revelan las condiciones de posibilidad de todo pensamiento acerca del Ser y la actual obsolescencia de todas las formas en las que este último ha sido previamente mentado. De este modo, un tenebroso y enjundioso proceso judicial, hoy caído en el olvido, nos muestra que custodiaba, sin saberlo, los secretos supremos de todo lo existente que la inveterada tradición ha dignificado con el nombre de Cosmos. Se anuncia, así, el comienzo de la Segunda Era Metafísica.

Nutritional value of plant purely depends on the methodology of cultivation. (Urmila Sarkar and Surendra Sawardekar) Different methods of cultivation lead to prior proficiency of plant growth in terms of germination, height, weight, nutritional factors and so on. (Urmila Sarkar and Surendra Sawardekar). A practice of 'Organic farming' for the production of quality based nutritional contents becomes an essential element. A crop such as Zea mays L. (Maize or Corn) is an important staple crop known for its wide range of nutritional component such as Carbohydrate, fats, proteins, minerals, vitamins, moisture, ash etc. (Urmila Sarkar and Surendra Sawardekar). The experimental research is focused on assessment of Protein content from organically grown Zea mays L. (maize/corn). The results conclude efficient amount of total protein in Zea mays L. plant material as a whole viz. root, leaf and seed.

In many cases new technologies are driven by the development of novel materials providing properties or combinations of properties that were not available before. The use of polymers and silicon-based semiconductor technologies are just two examples of how the availability of certain materials revolutionized existing technologies and products, giving rise to completely new technologies and having an enormous impact on our everyday life.

Background: In Greece, several new childhood vaccines were introduced recently but were reimbursed gradually and at different time points. The aim of this study was to assess immunization coverage and identify factors influencing complete and age-appropriate vaccination among children attending public nurseries in the municipal district of Athens. Methods: A cross-sectional study, using stratified sampling was performed. Immunization history was obtained from vaccination booklets. Demographic and socioeconomic data were obtained from school registries and telephone interviews. Vaccination rates were estimated by sample weighted proportions while associations between complete and age-appropriate immunization and potential determinants by logistic regression analysis. Results: A total of 731 children (mean age: 46, median: 48, range: 10-65 months) were included. Overall immunization coverage with traditional vaccines (DTP, polio, Hib, HBV, 1st dose MMR) was satisfactory, exceeding 90%, but the administration of booster doses was delayed (range: 33.7-97.4%, at 60 months of age). Complete vaccination rates were lower for new vaccines (Men C, PCV7, varicella, hepatitis A), ranging between 61-92%. In addition, a significant delay in timely administration of Men C, PCV7, as well as HBV was noted (22.9%, 16.0% and 27.7% at 12 months of age, respectively). Child's age was strongly associated with incomplete vaccination with all vaccines (p< 0.001), while as immigrant status was a predictor of incomplete (p=0.034) and delayed vaccination (p<0.001) with traditional vaccines. Increasing household size and higher maternal education were negatively associated with the receipt of all and newly licensed vaccines, respectively (p=0.035). Conclusions: Our findings highlight the need to monitor uptake of new vaccines and improve age-appropriate administration of booster doses as well as early vaccination against hepatitis B. Immigrant status, increased household size and high maternal education may warrant targeted intervention.

A high proportion of people with severe mental health problems are unemployed but would like to work. Individual Placement and Support (IPS) offers a promising approach to establishing people in paid employment. In a randomized controlled trial across six European countries, we investigated the economic case for IPS for people with severe mental health problems compared to standard vocational rehabilitation. Individuals (n5312) were randomized to receive either IPS or standard vocational services and followed for 18 months. Service use and outcome data were collected. Cost-effectiveness analysis was conducted with two primary outcomes: additional days worked in competitive settings and additional percentage of individuals who worked at least 1 day. Analyses distinguished country effects. A partial cost-benefit analysis was also conducted. IPS produced better outcomes than alternative vocational services at lower cost overall to the health and social care systems. This pattern also held in disaggregated analyses for five of the six European sites. The inclusion of imputed values for missing cost data supported these findings. IPS would be viewed as more cost-effective than standard vocational services. Further analysis demonstrated cost-benefit arguments for IPS. Compared to standard vocational rehabilitation services, IPS is, therefore, probably cost-saving and almost certainly more cost-effective as a way to help people with severe mental health problems into competitive employment.

Background. The interests in mesenchymal stem cells (MSCs) and their application in cell therapy have resulted in a better understanding of the basic biology of these cells. Recently hypoxia has been indicated as crucial for complete chondrogenesis. We aimed at analyzing bone marrow MSCs (BM-MSCs) differentiation capacity under normoxic and severe hypoxic culture conditions.Methods. MSCs were characterized by flow cytometry and differentiated towards adipocytes, osteoblasts, and chondrocytes under normoxic or severe hypoxic conditions. The differentiations were confirmed comparing each treated point with a control point made of cells grown in DMEM and fetal bovine serum (FBS).Results. BM-MSCs from the donors displayed only few phenotypical differences in surface antigens expressions. Analyzing marker genes expression levels of the treated cells compared to their control point for each lineage showed a good differentiation in normoxic conditions and the absence of this differentiatio...

Solid tumours account for 90% of all cancers. Gene therapy represents a potential new modality for their treatment. Up to now, several approaches have been developed, but the most efficient ones are the viral vector based gene therapy systems. However, viral vectors suffer from several deficiencies: firstly most vectors currently in use require intratumoural injection to elicit an effect. This is far from ideal as many tumours are inaccessible and many may have already spread to other parts of the body, making them difficult to locate and inject gene therapy vectors into. Second, because of cell heterogeneity within a given cancer, the vectors do not efficiently enter and kill every cancer cell. Third, hypoxia, a prevalent characteristic feature of most solid tumours, reduces the ability of the viral vectors to function and decreases viral gene expression and production. Consequently, a proportion of the tumour is left unaffected, from which tumour regrowth occurs. Thus, cancer gene therapy has yet to realise its full potential. The facultative or obligate anaerobic bacteria have been shown to selectively colonise and regerminate in solid tumours when delivered systemically. Among them, the clostridial spores were easy to produce, stable to store and safe to use as well as having extensive oncolytic ability. However, research in animals and humans has shown that oncolysis was almost always interrupted sharply at the outer rim of the viable tumour tissue where the blood supply was sufficient. These clostridial spores, though, could serve as "Trojan horse" for cancer gene therapy. Indeed, various spores harbouring genes for cancerstatic factors, prodrug enzymes, or proteins or cytokines had endowed with additional tumour-killing capability. Furthermore, combination of these "Trojan horses" with conventional chemotherapy or radiation therapies often significantly perform better, resulting in the "cure" of solid tumours in a high percentage of animals. It is, thus, not too difficult to predict the potential outcomes for the use of clostridial spores as "Trojan horse" vectors for oncolytic therapy when compared with viral vector-mediated cancer therapy for it be replication-deficient or competent. However, to move the "Trojan horse" to a clinic, though, additional requirements need to be satisfied (i) target tumours only and not anywhere else, and (ii) be able to completely kill primary tumours as well as metastases. Current technologies are in place to achieve these goals.

Personalized medicine is a new mantra evolving in health care. Harnessing each person&#39;s clinical, genetic, genomic, and environmental information drives the concept. The idea is simple. We can maximize a patient&#39;s chances of a better outcome if we base treatments on what we know. However, isn&#39;t this in many ways the way it&#39;s always been? Isn&#39;t this in part the basis for that old-time house call? To see how a disease or condition is being cared for in the home environment? Clinicians have long used personalized medicine, without overt use of single nucleotide polymorphisms, but certainly not totally void of genetic information. Of course, physicians of the past did not have gene chips, but they did have family histories often informing their decisions. Today as we raise the hopes for targeted therapies to break us free from the algorithmic treatments often followed by hit and miss approaches, there is a renewed fervor for personalized medicine. How do we get there...

Timely treatment of thyroid disease during pregnancy is important in preventing adverse maternal and fetal outcomes. Thyroid abnormalities are very often subclinical in nature and not easily recognized without specific screening programs. Even mild maternal thyroid hormone deficiency may lead to neurodevelopment complications in the fetus. The main diagnostic indicator of thyroid disease is the measurement of serum thyroid-stimulating hormone and free thyroxine levels. Availability of gestation-age-specific thyroid-stimulating hormone thresholds is an important aid in the accurate diagnosis and treatment of thyroid dysfunction. Pregnancy-specific free thyroxine thresholds not presently available are also required. Large-scale intervention trials are urgently needed to assess the efficacy of preconception or early pregnancy screening for thyroid disorders. Accurate interpretation of both antepartum and postpartum levels of thyroid hormones is important in preventing pregnancy-related complication secondary to thyroid dysfunction. This article sheds light on the best ways of management of thyroid dysfunction during pregnancy in order to prevent any possible maternal or fetal complication.

One of the aims of this research work is the isolation and identification of various constituents of two medicinally important plants (Iris loczyi and Iris unguicularis). Secondly, the prime aim is the biological evaluation of these natural products to discover new potential inhibitors of α-glucosidase enzyme and protein glycation. Main methods: Plants of the genus Iris contain a variety of secondary metabolites. Chromatographic techniques were applied for the isolation of different compounds from Iris loczyi and Iris unguicularis. All the isolated compounds were screened for their α-glucosidase enzyme inhibition and antiglycation potential. Key findings: It is shown in the results that two compounds (Kaempferol and 8-Methoxyeriodictyol) isolated from plant Iris unguicularis and compounds (Arborinone and 5,7-dihydroxy-2′,6-dimethoxyisoflavone) isolated from plant Iris loczyi possess promising activity against α-glucosidase enzyme as compare to acarbose which is used as a standard α-glucosidase inhibitor in this study. A flavanone (2′,5-dihydroxy-6,7-methylenedioxy) isolated from Iris loczyi was explored as most active anti-glycating agent. Significance: α-Glucosidase enzyme is a therapeutic target to treat carbohydrate mediated diseases. In this study various inhibitors of α-glucosidase are identified which might be important for the management of diabetes. Similarly, antiglycation agents may have application for the management of late diabetic complications.

To assess the effectiveness of the current UK clinical practice in reducing hepatic fat (IHCL). Whole body MRI and (1)H MRS were obtained, before and after 6 mo nutritional counselling, from liver, soleus and tibialis muscles in 10 subjects with non-alcoholic fatty liver disease (NAFLD). A 500 Kcal-restricted diet resulted in an average weight loss of 4% (-3.4 kg,) accompanied by significant reductions in most adipose tissue (AT) depots, including subcutaneous (-9.9%), abdominal subcutaneous (-10.2%) and intra-abdominal-AT (-11.4%). Intramyocellular lipids (IMCL) were significantly reduced in the tibialis muscle (-28.2%). Decreases in both IHCL (-39.9%) and soleus IMCL (-12.2%) content were also observed, although these were not significant. Several individuals showed dramatic decreases in IHCL, while others paradoxically showed increases in IHCL content. Changes in body composition were accompanied by improvements in certain liver function tests: serum aspartate aminotransferase (A...

Sarcoplasmic reticulum (SR), Ca *+ + Mg *+-ATPase, and Ca *+-ioncphore were obtained from white rabbit skeletal muscles. Methylmercury inhibited the Ca *+ + Mg*+-ATPase an d Ca**-transport but had no effect on the Ca*+ionophore. Mercuric chloride inhibited all three functions (i.e., ATPase, transport and ionophoric activity). The mechanism of HgC12 inhibition of the Ca*+ionophore was by competition with Ca*+ for Ca*'-ionophoric site whereas its inhibition of the enzyme ar,d Ca*+-transport was due to the blockage of essential sulfhydryl (-SH) groups. Ca*' + Mg*+-ATPase and Ca*+-transport were more sensitive to methylmercury than to HgC12. Acetylcholine receptor (AChR) was obtained for the electric organ of T.

The synthesis and structure-activity relationships (SAR) of p38a MAP kinase inhibitors based on a pyrazolo-pyrimidine scaffold are described. These studies led to the identification of compound 2x as a potent and selective inhibitor of p38a MAP kinase with excellent cellular potency toward the inhibition of TNFa production. Compound 2x was highly efficacious in vivo in inhibiting TNFa production in an acute murine model of TNFa production. X-ray co-crystallography of a pyrazolo-pyrimidine analog 2b bound to unphosphorylated p38a is also disclosed.

Abstract— Irradiation of 1,3–dimethyluracil (DMU) in 1–aminopropane (AP) with u.v. light resulted in the formation of reduced and dimeric forms of DMU and adducts between DMU and AP. The formation of these compounds may be rationalized from the activation of either DMU or AP. Irradiation of DMU and poly-l-lysine in water with u.v. light resulted in the extensive binding of DMU to poly-l-lysine. The pyrimidine is probably attached to the ε-carbon of the polypeptide at the 6–position. The biological implications of these studies are discussed.

There are currently no assessment tools that focus on evaluating patients with multiple sclerosis (MS) who are experiencing a relapse or that evaluate patients&#39; response to acute relapse treatment. In practice, assessments are often subjective, potentially resulting in overlooked symptoms, unaddressed patient concerns, unnoticed or underrecognized side effects of therapies (both disease modifying and symptomatic), and suboptimal therapeutic response. Systematic evaluation of specific symptoms and potential side effects can minimize the likelihood of overlooking important information. However, given the number of potential symptoms and adverse events that patients may experience, an exhaustive evaluation can be time-consuming. Clinicians are thus challenged to balance thoroughness with brevity. A need exists for a brief but comprehensive objective assessment tool that can be used in practice to 1) help clinicians assess patients when they present with symptoms of a relapse, and 2...

Objectives: Malaria infection of the placenta during pregnancy was found to be associated with infant susceptibility to malaria. Other factors such as the intensity of malaria transmission and the nutritional status of the child might also play a role, which has not been adequately taken into account in previous studies. The aim of this study was to assess precisely the parts played by environmental, nutritional and biological determinants in first malaria infections, with a special interest in the role of placental infection. The objective of this paper is not to present final results but to outline the rationale of the study, to describe the methods used and to report baseline data.

Involvement of nitric oxide (NO) in the episodic secretion of prolactin was studied in conscious freely moving adult rats. Prolactin secretion was pulsatile in all animals of either group during the bleeding period (from 10:30 h to 13:30 h). Administration of N ω -nitro-L-arginine ...

The Wiskott-Aldrich syndrome (WAS), X-linked severe combined immunodeficiency (SCIDXl), and X-linked agammaglobulinemia (XLA) are severe congenital immunodeficiencies with X-linked inheritance. Although rare, they are all associated with severe infections from early in life, and high morbidity and mortality. Female carriers of these diseases can be identified by a non-random pattern of X-chromosomal inactivation in cell lineages targeted by each gene defect. For patients with WAS, SCIDXl or XLA, the demonstration of non random X-Chromosome inactivation in their mothers can be used to confirm clinical diagnosis. Furthermore, analysis of X-Chromosome inactivation in at risk females allows preconceptional carrier detection, thus representing an important aid in genetic counseling. For each disease we established a PCR-based, non radioactive assay at the human androgen receptor (HUMARA) locus, that allows analysis of X-Chromosome inactivation in the affected cell types and in tissue specific controls to exclude the issue of skewed X-chromosomal inactivation. In our study, 50 females with a known family history of XLA [19], WAS [18], and SCIDXl [ 13],were examined. A carrier status was established in 19 females (7 XLA, 6 WAS, 6 SCIDXl) and excluded in 29 ( 11 XLA, 11 WAS, 7 SCIDXl). Only in 2 cases (4%) the assay was not informative. In females, one of the two X-Chromosomes is inactivated in somatic cells early in embryogenesis. Inactivation occurs randomly, but once established, the same X-Chromosome is inactivated in all progeny cells (1). Therefore, in normal females, half of the cells in any tissue has the maternally derived X as the active X-Chromosome and half the paternally derived one. However, if one of the two X-Chromosomes carries a gene defect that is detrimental to proliferation and/or survival of a particular cell lineage, all the cells of that lineage will demonstrate preferential inactivation of the mutated X-Chromosome.

Refeeding syndrome (RFS) describes the biochemical changes, clinical manifestations, and complications that can occur as a consequence of feeding a malnourished catabolic individual. RFS has been recognised in the literature for over fifty years and can result in serious harm and death. Crude estimates of incidence, morbidity, and mortality are available for specific populations. RFS can occur in any individual but more commonly occurs in at-risk populations. Increased awareness amongst healthcare professionals is likely to reduce morbidity and mortality. This review examines the physiology of RFS and describes the clinical manifestations. A management strategy is described. The importance of a multidisciplinary approach is emphasized.

We identified a novel endogenous protein inhibitor of Na + /K + -ATPase having an apparent mol mass of 70 kDa in the cytosolic fraction of the smooth muscle. The IC 50 value of the inhibitor towards the enzyme was determined to be in the nanomolar range. Important ...

Reflexology is one of the non-pharmacological pain relief methods, and since it is a non-invasive, inexpensive and applicable technique, it can be used by a skilled and trained midwife. This study aimed to review the effect of reflexology on the pain and outcomes of the labor. In this quasi-experimental study, 88 primiparous mothers referred to selected hospitals of Isfahan for vaginal delivery were selected using simple random sampling method and then randomized in two groups. Data collection tools were the demographic data questionnaire, profile and outcomes of the labor and the short-form of the McGill Questionnaire for Pain Rating Index (PRI) assessment. The intervention was general and specific reflexology in the active phase of labor. PRI was assessed before the intervention and four times after the intervention (3-5 cm, 6-8 cm and 9-10 cm dilatations and second stage of labor. There was no significant difference between groups before intervention. In the reflexology group, th...

Frontal plane running mechanics may contribute to the etiology or exacerbation of common running related injuries. Hip strengthening alone may not change frontal plane hip and knee joint running mechanics. The purpose of the current study was to evaluate whether a training program including visual, verbal, and tactile feedback affects hip and knee joint frontal plane running mechanics among females with evidence of altered weight bearing kinematics. The knee frontal plane projection angle of 69 apparently healthy females was determined during a single leg squat. The twenty females from this larger sample who exhibited the most acute frontal plane projection angle (medial knee position) during this activity were chosen to participate in this study (age = 20 ± 1.6 years, height = 167.9 ± 6.0 cm, mass = 63.2 ± 8.3 kg, Tegner Activity Rating mode = 7.0). Participants engaged in a 4-week movement training program using guided practice during weight bearing exercises with visual, verbal, ...

Constipation is a common symptom in infants and young children who are seen by primary care physicians. If a patient fails to respond to the appropriate medical therapy for constipation, then the physician should consider the possibility of Hirschsprung&#39;s disease, a congenital disease in which ganglion cells are absent from the distal gastrointestinal tract, and which results in a functional colonic obstruction. Early diagnosis and prompt treatment of Hirschsprung&#39;s disease will result in a significantly improved quality of life for the patient, and may alleviate potentially life-threatening complications. This article describes a case of Hirschsprung&#39;s disease and reviews the most current literature on the topic. Clinical features that distinguish Hirschsprung&#39;s disease from other causes of constipation are emphasized.

Background: While robotic surgery for gynecologic indications received U.S. government approval in 2005, and has been rapidly and widely adopted, it is currently unclear how often this approach to hysterectomy is utilized. Objective: The aim of this research was to assess length of stay (LOS), mortality, indications, and current use of robotic hysterectomy, compared to other types of hysterectomy. Methods: A retrospective study of hysterectomies performed in New York State (NYS) in 2011 was performed. Data, including indication for surgery, age, procedure, LOS, and discharge status were obtained from the NYS Department of Health Statewide Planning and Research Cooperative System (SPARCS). Outcome Measures: LOS and mortality rate, were calculated according to institution, procedure, and indication for surgery. Results: For 22073 hysterectomies performed in NYS, the mean LOS was 2.9 days, and there were 29 (0.13%) deaths. The mean LOS for abdominal (12774 cases, 3.9 days) hysterectomies was longer than for laparoscopic (3927 cases, 1.6 days), robotic (2814 cases, 1.6 days), or vaginal (2558 cases, 1.7 days) hysterectomies (p < 0.05). The adjusted mortality rates for abdominal (0.20%), laparoscopic (0.03%), robotic (0.07%), and vaginal (0.04%) hysterectomies were not significantly different. Overall, robotic surgery was performed in 29% of hospitals, by 11% of physicians and in 13% of cases. A robotic approach was utilized in 35% of patients with uterine cancer, 13% with endometriosis, 11% with excessive bleeding, 8% with leiomyomata, and 8% with pelvic relaxation. Conclusions: Despite the advantages in reduced LOS for robotic and other minimally invasive types of hysterectomies, the abdominal route is still predominant in most institutions.

Limited recovery of islets post-cryopreservation influences graft survival and transplantation efficiency during diabetes treatment. As curcumin, a potent antioxidant/radical scavenging compound, protects islets against beta cell toxins, we hypothesized that inclusion of curcumin during cryopreservation or during post-thaw culture or both may rescue islets from cryoinjury. To test the effect of curcumin inclusion on islet recovery murine islets were isolated by the collagenase digestion, cultured for 48 h, cryopreserved using dimethylsulphoxide as cryoprotectantwith or without curcumin (10 μM)and then slow cooled to −40°C before immersing them in liquid nitrogen for 7 days. Following rapid thawing with sucrose gradient and 24 h post-thaw culturein presence or absence of curcumin (10 μM)islet viability and functionality were determined. Islet recovery in curcumin treated groups was significantly higher than in groups where islets were cryopreserved without curcumin. Islets cryopreserved with curcumin also showed more intact islets as well as better morphology as compared to islets cryopreserved without curcumin. Curcumin treated islets also showed significant inhibition of ROS generation as compared to islets cryopreserved without curcumin. Glucose responsiveness and insulin secretion in islets cryopreserved with curcumin was equal to that of the freshly isolated islets as against islets cryopreserved without curcumin. Elevated level of Hsp 70 and HO-1 were observed in islets cryopreserved with curcumin and may contribute to curcumin-induced islet rescue. Hence, we conclude that inclusion of curcumin into cryopreservation medium inhibits ROS generation and corresponding islet damage and dysfunction.

Introduction: Ecthyma gangrenosum is known as a characteristic lesion of Pseudomonas aeruginosa sepsis and is usually seen in immunocompromised patients. Case presentation: A previously healthy 63-year-old man was admitted with sloughy necrotic ulcerations of the skin over his sternum. He was afebrile and in good condition. A skin biopsy revealed ecthyma gangrenosum. Blood cultures remained sterile, but a culture of biopsy material grew Pseudomonas aeruginosa. Conclusion: Ecthyma gangrenosum may develop even in the absence of bacteremia and even in immunocompetent patients. It should be considered as a possible diagnosis even when a previously healthy patient has negative blood cultures. The patient had no history of immunosuppressive disease or treatment. On admission he was afebrile (temperature of 37,2°C), and hemodynamically stable. Physical examination revealed two sloughy necrotic ulcerations of the skin over

Motivated by neuropsychological investigations of category-specific impairments, many functional brain imaging studies have found distinct patterns of neural activity associated with different object categories. However, the extent to which these category-related activation patterns reflect differences in conceptual representation remains controversial. To investigate this issue, functional magnetic resonance imaging (fMRI) was used to record changes in neural activity while subjects interpreted animated vignettes composed of simple geometric shapes in motion. Vignettes interpreted as conveying social interactions elicited a distinct and distributed pattern of neural activity, relative to vignettes interpreted as mechanical actions. This neural system included regions in posterior temporal cortex associated with identifying human faces and other biological objects. In contrast, vignettes interpreted as conveying mechanical actions resulted in activity in posterior temporal lobe sites associated with identifying manipulable objects such as tools. Moreover, social, but not mechanical, interpretations elicited activity in regions implicated in the perception and modulation of emotion (right amygdala and ventromedial prefrontal cortex). Perceiving and understanding social and mechanical concepts depends, in part, on activity in distinct neural networks. Within the social domain, the network includes regions involved in processing and storing information about the form and motion of biological objects, and in perceiving, expressing, and regulating affective responses.

Fifty-one of the 58 students (87.9 per cent) participated. The weekly average study time was 29.9 hours. Lecture handouts and textbooks were commonly used information sources. The mean scores (scale 1 to 5) for learning-issuedriven searching, and extensiveness of searching were 3.49 and 3.45, respectively. The score for explanation-oriented preparation was 3.94, while those for breadth and depth of discussion were 3.75 and 3.62, respectively. Most scores were higher among second-semester students, but the difference was not significant.

Diffusion tensor MRI (DTI) is now a widely used modality to investigate the fiber tissues in vivo, especially the white matter in brain. An automatic pipeline is described in this paper to conduct a localized voxel-wise multiple-subject group comparison study of DTI. The pipeline consists of 3 steps: 1) Preprocessing, including image format converting, image quality check, eddy-current and motion artifact correction, skull stripping and tensor image estimation, 2) study-specific unbiased DTI atlas computation via affine followed by fluid nonlinear registration and warping of all individual DTI images into the common atlas space to achieve voxel-wise correspondence, 3) voxelwise statistical analysis via heterogeneous linear regression and wild bootstrap technique for correcting for multiple comparisons. This pipeline was applied to process data from a fitness and aging study and preliminary results are presented. The results show that this fully automatic pipeline is suitable for voxel-wise group DTI analysis.

Background: DNA hypermethylation and histone deacetylation are epigenetic events that contribute to the absence or downregulated expression of different components of the tumor recognition complex. These events affect the processing and presentation of antigenic peptides to CTLs by HLA class-I molecules. In this work evaluated the effect of the DNA hypomethylating agent hydralazine and the histone deacetylase inhibitor valproic acid, on the expression of HLA class-I molecules and on the antigen-specific immune recognition of cervical cancer cells.

Effect of mitragynine, an indole alkaloid isolated from Thai medicinal plant kratom (Mitragyna speciosa), on electrically stimulated contraction was studied in the guinea-pig ileum. Mitragynine (1 nM - 3 μM) inhibited the ileum contraction elicited by electrical stimulation, and its pD2 value was 6.91 ± 0.04 (n = 5). Morphine (1 nM − 1 μM) also inhibited the electrically stimulated contraction in a concentration-dependent manner (pD2 7.68 ± 0.11; n = 5). Mitragynine was 10 fold less potent than morphine. Mitragynine (3–10 μM) did not show any effect on the smooth muscle contraction induced by acetylcholine or histamine. Naloxone (10–300 nM) reversed the inhibitory effect of mitragynine on electrically stimulated contraction. Furthermore, naloxone showed a shift of concentration-response curve of mitragynine to the right. There was no significant difference in the affinity of naloxone (i.e. pA2) in the presence of mitragynine or morphine. Mitragynine (3–10 μM) inhibited the naloxone-precipitated withdrawal contraction following a brief (5 min) exposure of the ileum to morphine. Tetrodotoxin (1 μM) and atropine (1 μM) inhibited the withdrawal contraction. The present results suggest that mitragynine inhibits the electrically stimulated contraction of guinea-pig ileum through the opioid receptor.

Background: General psychiatric and forensic psychiatric beds, supported housing and the prison population have been suggested as indicators of institutionalized mental health care. According to the Penrose hypothesis, decreasing psychiatric bed numbers may lead to increasing prison populations. The study aimed to assess indicators of institutionalized mental health care in post-communist countries during the two decades following the political change, and to explore whether the data are consistent with the Penrose hypothesis in that historical context. Methodology/Principal Findings: General psychiatric and forensic psychiatric bed numbers, supported housing capacities and the prison population rates were collected in Azerbaijan,
