Recent Findings Current knowledge on the epidemiology and global burden of this infection is scarce. In part, because it remains a largely underdiagnosed clinical entity, and also since many countries do not officially recognize it as endemic, this has led to a lack of surveillance and underreporting, not considering it an officially notifiable disease. Recent reports have shown broad variability of seroprevalence rates amongst different countries. Summary Human toxocariasis is a zoonotic parasitic disease that would represent high morbidity in many countries. Caused by Toxocara canis and Toxocara cati, clinical spectrum of this systemic helminthiasis can be extended from asymptomatic forms up to life-threating syndromes such as the visceral larva migrans.

El presente estudio tiene como objetivo analizar el contexto de aplicación de los principios constitucionalizados que rigen la contratación pública en el sistema ecuatoriano. Para cumplimentar el mismo se realizó una revisión bibliográfica para analizar lo abordado por la literatura científica publicada sobre la temática objeto de estudio, lo que avala el empleo de un enfoque teórico descriptivo. Metodológicamente las fuentes fueron seleccionadas mediante el uso de criterios de inclusión y exclusión. Formaron parte de los primeros los documentos legales que norman el proceder respecto al tema en estudio e investigaciones publicadas en los últimos cinco años en repositorios y bases de datos indexadas como Scopus; Scielo; Latindex; Dialnet; Redib; Amelica. Tras la búsqueda realizada, se incluyeron 21 artículos para su revisión. El...

They are TRIMS and GATS. According to these agreements, China should strengthen relevant laws and regulations quickly, simplify the examination and approval system for foreign investment, and increase the transparency of examination and approvel. We must also extend the opening field of the third industry. All these policies can improve our whole investment environment and adjust our investment structure. So joining WTO can improve foreign direct investment in China.

Los sistemas electorales constituyen procedimientos de formación de órganos de representación política en elecciones. Así, las y los electores expresan sus preferencias políticas en votos; el sistema electoral regula cómo ese voto se convierte en escaños (Nohlen 2006). El impacto de las reglas electorales es de tal magnitud que aplicar un sistema electoral sobre una votación cualquiera tendrá un resultado distinto si se aplica otro sistema electoral sobre esa misma votación, por lo que “escoger un sistema electoral determinado pasa a convertirse en una decisión política de vital importancia para un país” (Tuesta 2005, 17). En el presente artículo se analiza el sistema electoral parlamentario peruano, así como el impacto de las principales reformas implementadas en las Elecciones Generales 2021, desde la perspectiva de la historia de las elecciones parlamentarias de este siglo. ...

A qualitative phenomenological study was conducted with five black college students. They participated in entrance interviews, a white studies workshop that incorporated a focus group, wrote reflective journals, had exit interviews, and a group debriefing session. The data were analyzed and interpreted through the theoretical lenses of Critical Race Theory and Transformative Learning Theory. A textual analysis of the data revealed two overarching themes. Those themes are the oppressive acts of racism and the revelations from white studies. The participants' white studies experience revealed the power of hearing other students' stories about their experiences with racism, opened their eyes to certain aspects and manifestations of whiteness, provided them with language to use, and fostered strategies about how to respond to racist offenders. Those findings led to a few implicat...

CEA is done in order to prevent cerebral vascular accidents (CVAs) or strokes. There is a high risk of morbidity and mortality, such as myocardial infarction and CVA, associated with this procedure. Therefore, different types of anesthetic management and various neuromonitoring techniques have been recommended by investigators. General anesthesia with inhaled anesthetics has demonstrated better neuroprotection from focal cerebral ischemia when compared with regional anesthesia. Regional anesthesia has been associated with less hemodynamic fluctuation and decreased risk of perioperative myocardial ischemia. Superficial, intermediate, and deep cervical plexus blocks (or a combination of superficial and deep cervical plexus blocks) are recognized regional anesthetic techniques utilized for CEA. In addition, neuromonitoring techniques such as somatosensory evoked potentials, motor-evoked potential...

This paper has proposed the real time image classification for burning image to automatically identify the degrees of burns in three levels: II, III, and IV. The proposed model uses the multi-colour channels extraction and binary based on adaptive threshold. The proposed model uses One-class Support Vector Machine instead of traditional Support Vector Machine (SVM) because of unbalanced degrees of burns images database. The classifying precision 77.78% shows the feasibility of our proposed model.

These precursors are synthesized either by the mevalonate (MVA) pathway or the 1-Deoxy-D-Xylulose 5-Phosphate (DXP) pathway. Metabolic engineering of microbes has enabled overproduction of various isoprenoid products from the DXP pathway including lycopene, artemisinic acid, taxadiene and levopimaradiene. To date, there is no method to accurately measure all the DXP metabolic intermediates simultaneously so as to enable the identification of potential flux limiting steps. In this study, a solid phase extraction coupled with ultra performance liquid chromatography mass spectrometry (SPE UPLC-MS) method was developed. This method was used to measure the DXP intermediates in genetically engineered E. coli. Unexpectedly, methylerythritol cyclodiphosphate (MEC) was found to efflux when certain enzymes of the pathway were over-expressed, demonstrating the existence of a novel competing pathway branch in the DXP metabolism. Guided by these findings, ispG was overexpressed and was found to effectively reduce the efflux of MEC inside the cells, resulting in a significant increase in downstream isoprenoid production. This study demonstrated the necessity to quantify metabolites enabling the identification of a hitherto unrecognized pathway and provided useful insights into rational design in metabolic engineering.

In the study Null and alternative hypothesis have been constructed, Null hypothesis is concerning the negation of the moderating effect of firm size, while alternative hypothesis is pertaining to the acceptance of the moderating inspiration of firm size between the relationship of firm growth and firm performance. For this purpose, the secondary cross-sectional data has been gathered from 50 firms listed in Karachi stock Exchange. Before application of regression equation the formality of stationary of data has been fulfilled, in addition the issue of the multi-co-linearity has also been resolved. The results of the regression analysis are demonstrating that the alternative hypothesis of the research that firm size has moderating inspiration between independent variable (Firm growth) and dependent variable (Firm performance) is accepted. The study is cooperative for the management to keep an eye on firm size along with firm growth while enhancing the firm performance. The future aspects of the research have also been discussed.
