Enantioselective syntheses of the potent antifungal agent (-)-jesterone, its hydroxy epimer, and a dimeric quinone epoxide derivative are reported. The synthesis involves diastereoselective epoxidation of a chiral quinone monoketal derivative and regio- and stereoselective reduction of a quinone epoxide intermediate.
An unusual case of extensive benign lymphoid hyperplasia of the ileo-caecal region causing ileo-caeco-colic intussusception is presented here, with a review of relevant literature. The diagnosis of intussusception was reached with the help of an abdominal ultrasound and barium enema. Histopathology of the resected specimen, revealed lymphoid hyperplasia.
We present an unusual case of suppurative pericarditis following rupture of a solitary right lobe amebic liver abscess. The condition was treated successfully by drainage of the liver abscess alone.

Seminal plasma proteins of the Indian buffalo and cattle were immunologically investigated using rabbit antibuffalo seminal plasma serum, rabbit anticattle seminal plasma serum (unabsorbed and absorbed), gel diffusion, and immunoelectrophoretic analysis. At least 9-12 and 7-10 different proteins, respectively, were present in the seminal plasma of the buffalo and cattle. Albumin and IgG were identified in both the species. At least 4-6 seminal plasma proteins of the buffalo and cattle were antigenically similar to their blood serum proteins. Using absorbed rabbit antibuffalo seminal plasma serum and rabbit anticattle seminal plasma serum, at least 6-7 and 5-6 seminal plasma specific proteins, respectively, were observed in the buffalo and cattle seminal plasma. Antigenically these proteins were different from the blood serum proteins of these two species. The origin and biological significance of seminal plasma proteins are discussed.
Seminal plasma immunoglobulins of normospermic fertile Indian buffalo bulls were investigated using rabbit antibuffalo immunoglobulin (polyvalent) serum, rabbit antibuffalo IgG and IgM serums, gel diffusion, and immunoelectrophoretic analysis. Immunoglobulin G was the predominant immunoglobulin in the seminal plasma of the buffalo. Strong antigenic cross reactions were observed between the seminal plasma IgG molecules of the buffalo and cattle, indicating the structural homology of seminal plasma IgG of these two species. These observations are in accordance with the close taxonomic and phylogenetic relationship between buffalo and cattle in the evolution of ruminant species.

Fetal specific serum proteins of the Indian buffalo were investigated using rabbit antibuffalo fetal serum, absorbed with lyophilised adult buffalo serum, and subjected to gel diffusion and immunoelectrophoretic analysis. AFP was found to be the major fetal specific serum protein of the Indian buffalo. A close antigenic relationship between the fetal specific serum proteins of the buffalo, sheep and goat and a distant relationship between these proteins of ruminants and man was found by immunological cross reaction studies.

4-Bromophenethyl alcohol was protected as the THP ether, followed by reaction with magnesium and selenium to give the corresponding diselenide. Ether deprotection provides a diselenide diol, which is attached to solid-phase resins. The polymer-bound selenide anion is then generated, and functions as a traceless linker for electrophiles such as alkyl halides.
