Background & Aims: The most significant cause of infertility in men is the genetic deletion in the azoospermia factor (AZF) region that is caused by the process of intra- and inter-chromosomal homologous recombination in amplicons. Homologous recombination could also result in partial deletions in AZF region. The aim of this research was to determine the association between the partial AZFc del...

Two high molecular weight glycoproteins, exposed on the surface of sympathetic neurons, are modified after they have been translated, glycosylated, and inserted in the plasma membrane. B1 (apparent Mr = 230,000 by electrophoresis in sodium dodecyl sulfate) and B3 (Mr approximately 200,000) are each modified to give proteins of lower apparent molecular weight: B2 (Mr approximately 215,000) and B...

The product organ (storage organ; corm) of the Chinese water chestnut has become a very popular food in Asian countries because of its unique nutritional value. Corm formation is a complex biological process, and extensive whole genome analysis of transcripts during corm development has not been carried out. In this study, four corm libraries at different developmental stages were constructed, ...

a) i. The best response strategies are A: cache only if nobody else does. (B1) B: cache if neither A nor D cache. (B2) C: cache unless A caches. (B3) D: cache if neither A nor B cache. (B4) Nash equilibrium. If we assume that A plays xA = 1 (A caches) the system can only be in a NE if xB = xC = xD = 0 due to (B1). Since for all B, C, and D it is the best response not to cache if A does, x = (10...

Some of organic ammonium salts, namely: 2-((4-carboxyphenyl) carbamoyl) benzoate tetraethylammonium, B1, 4-oxo-4-(pyridin-3-ylamino)-2-butenoate B2, 2-((4-carbamoylphenyl) B3, 4-((4-carbamoylphenyl)amino)-4-oxobutanoate B4, are successfully synthesized as ionic liquids. By spectral techniques FTIR, 1H-NMR and 13C-NMR the structures salts confirmed. The thermal analysis by differential scanning ...

We investigated the antimicrobial activity of four polymyxin B components, B1, B2, B3, and isoleucine (Ile)-B1, individually and in combination. B3 was the most active agent against all organisms tested except Acinetobacter baumannii, for which Ile-B1 was most active. One combination met the criteria for synergy, B3 plus Ile-B1. No combinations exhibited antagonism. The dominant components of p...

Exposed on the cell surface of sympathetic neurons in culture is a family of high molecular weight glycoproteins (B1, B2, B3, and B4, related to the NILE protein) which undergoes post-translational modification (Sweadner, K. J. (1983) J. Neurosci. 3: 2504-2517). B1 and B3 are converted to B2 and B4 by what might be limited proteolysis. These proteins normally require detergents to release them ...
