The sperm-rich fraction of Large White semen, diluted 1:3 and kept at 8-15 deg C, was used to find the optimum levels of 1-, 2-, 3- and 4-sodium-EDTA in a diluent containing 3.15% glucose, 0.918% potassium sodium tartrate, 3% egg yolk, 1000 IU/ml penicillin and 1 mg/ml streptomycin. The best results were obtained with 0.15% 4-sodium-EDTA plus 0.025% citric acid, which maintained levels of 73, 71, 68, 66, 65 and 63% sperm motility after 1, 2, 3, 4, 5 and 6 days of storage resp.

A series of novel dispirooxindolopyrrolizidine derivatives have been synthesized through 1,3-dipolar cycloaddition reaction of azomethine ylide generated from proline and isatin with the dipolarophile (E)-2-arylidine-1-keto carbazoles. The synthe...

Genetic factors play a critical role in the etiology of bipolar disorder (BPAD). Previous studies suggested an association between thyroid dysfunction and BPAD. We hypothesize that genetic variations in the type II deiodinase (DIO2) gene that poss...

We present an approach to laparoscopic radical nephrectomy and intact specimen extraction, which incorporates hand assisted and standard laparoscopic techniques. A refined approach to laparoscopic radical nephrectomy is described and our experienc...

This analog proved to be indistinguishable from SCT with respe...
