Inappropriate location is difficult to correct secondarily. Traditional methods of nipple localization taught and practiced suggest the nipple to be located anterior to the inframammary fold. Trying to project this point on the anterior surface of the breast requires either large calipers or feeling the posteriorly placed finger on the anterior surface of a large breast. This certainly introduces some subjectivity to the calculation. OBJECTIVES: To introduce an easy and accurate method of nipple localization to reduce the learning curve for trainee surgeons. METHODS: Aesthetic placement of the nipples is at the lower angles of an equilateral or a short isosceles triangle on the chest with its apex at the sternal angle. This triangle can be thought of as two right-angled triangles with their Y-axis on the median plane. The base and vertical limb are measured, and the hypotenuse is calculated. The location of the lower angle is marked on the anterior surface of the breast and represents the new position of the nipple. RESULTS: Forty patients had nipple localization performed in the above-described manner, with satisfactory placement of the nippleareola complex. CONCLUSIONS: The above technique introduces some objective measurements to the localization of the nipple in breast reduction surgery. It is easy to practice, and infuses confidence in trainees marking their initial breast reductions.

The General Agreement on Tariffs and Trade (GATT) came into being in 1947 with a separate Dispute Settlement System to resolve trade disputes amongst member countries. Due to the dominance of great economic powers such as United States, U.K, Japan & Canada, the GATT was gradually dubbed as a ‘rich man’s club leading to reform process. Under the new system, a Dispute Settlement Body (DSB) consisting of dispute panels and an Appellate Body now adjudicates trade disputes between the parties. There is no iota of doubt that the Dispute Settlement Mechanism of WTO has worked more efficiently, independently and impartially than other international and judicial courts or tribunals. This paper examines the gradual development of dispute settlement system under GATT and WTO. Reflecting on north-south divide, it focuses on Tokyo Round Negotiations and Uruguay Round Negotiations in some detail and also compares and contrasts GATT and WTO’s Dispute Settlement Mechanism in the multilateral trade regime.

Lata, Minicate, Nazersail, Parija, Kalijira and Kataribhog, to the infestation of the rice weevil, Sitophilus oryzae (L.), was studied on the basis of population build up under an ambient condition (28 ± 4ºC and 70 ± 4 % RH) of the laboratory. The mean weights of each grain of the above six rice varieties were 16.9, 16.1, 11.43, 13.87, 6.23 and 9.77 mg, respectively; mean lengths were 6.47, 6.56, 5.37, 5.38, 4.22 and 4.92 mm, respectively; mean widths were 2.45, 2.03, 2.05, 2.17, 1.6 and 1.9 mm, respectively; and moisture contents were 11.55, 10.75, 11.6, 12.71, 11.85, and 12.1 per cents, respectively. As far as the number of emerging adults is concerned, the weevil showed the highest number (695) in Nazersail on the 16th week, Lata (755) on the 18th week, Minicate (654) on the 16th week, Parija (482) on the 20th week, Kalijira (402) on the 20th week, and Kataribhog (456) on the 20th week. The mean numbers of the adult ...

The female reproductive system of B. peregrina comprises of two ovaries, two lateral oviducts, a common oviduct, three spermathecae, and a pair of accessory gland, a bilobed incubation pouch, vagina and genital opening. The male reproductive system B. peregrina consists of a pair of testes, a pair of vasa deferentia, a pair of accessory gland, a median ejaculatory duct, an ejaculatory sac and aedeagus. There is a general trend of gradual development of different organelles of the male and female reproductive systems from adult emergence to reproductive maturity. Protein diet was essential for proper development of female reproductive system. Oocyte development was apparent in both protein fed and protein u...

As far as we know, this technique has not been reported elsewhere.

The DegU orphan response regulator is known to control heat resistance in L. monocytogenes; however, the underlying regulatory mechanism is poorly understood. Here, we show that DegU contributes to L. monocytogenes exponential growth under mild heat-shock stress. We further demonstrate that DegU directly senses heat stress through autoregulation and upregulates the hrcA-grpE-dnaK-dnaJ operon, leading to increased production of heat-shock proteins. We also show that DegU can directly regulate the expression of the hrcA-grpE-dnaK-dnaJ operon. In conclusion, our results shed light on the regulatory mechanisms underlying how DegU directly activates the hrcA-grpE-dnaK-dnaJ operon, thereby regulating heat resistance in L. monocytogenes.
