The cytoplasmic membrane is probably the most important physical barrier between microbes and the surrounding habitat. Aminoacylation of the polar head group of the phospholipid phosphatidylglycerol (PG) catalyzed by Ala-tRNA(Ala)-dependent alanyl-phosphatidylglycerol synthase (A-PGS) or by Lys-tRNA(Lys)-dependent lysyl-phosphatidylglycerol synthase (L-PGS) enables bacteria to cope with cationi...

This paper concerns the maximum power extraction of a photovoltaic generator system (PGS). The PGS consists single (PV) cells. To improve efficiency PGS, it is necessary to work within its point (MPP). In output dependent on solar irradiance and operating temperature and, therefore, MPP would be varied. address this problem, converter should placed after smooth control signal used adjust duty c...

Glycerol (G), polyglycerols (PGs), glycerol triacetate (GTA), and tributyrate (GTB) were studied as additives of poly(3-hydroxybutyrate) (PHB). The effect different concentrations (5–30%) these compounds on microstructure final properties PHB films evaluated. Microscopic studies revealed that samples with GTA GTB presented uniform microstructure, meanwhile those containing G PGs evidenced exuda...

Stimulating hormone for artificial fish breeding in hatchery industry is very crucial hatching operation, healthy fry and fingerling production, while overall production of a country. The present study was conducted to assess the effectiveness using local overseas Carp Pituitary Gland (CPG) induced Cirrhinus mrigala at Jashore district from April May 2022. first dose hormone, both male female b...

Partial genome sequencing (PGS) and restriction fragment analysis (RFA) are used frequently in molecular epidemiologic investigations. The relative accuracy of PGS and RFA in phylogenetic reconstruction has not been assessed. In this study, 32 model phylogenetic trees with 16 extant lineages were generated, for which DNA sequences were simulated under varying conditions of genome length, nucleo...

Diapause, a programmed developmental arrest at a specific stage, is common in insects and is regulated by hormones. It is well established that in pupal diapause, cessation of ecdysteroid secretion from the prothoracic glands (PGs) after pupal ecdysis leads to diapause initiation, while resumption of its secretion induces post-diapause development. However, what regulates the activity of the gl...

The ability of prostaglandin synthetase (PGS) to cooxidize benzo(a)pyrene, benzo(a)anthracene, chrysene, and several of their dihydrodiol derivatives to mutagenic products was tested with Salmonella typhimurium strains TA98 and TA100. The microsomal fraction of ram seminal vesicles, a known source of PGS, in the presence of the PGS substrate arachidonic acid, metabolized benzo(a)pyrene-7,8-dihy...

OBJECTIVE To determine whether in vitro fertilization with preimplantation genetic screening (IVF/PGS) is cost effective compared with expectant management in achieving live birth for patients with unexplained recurrent pregnancy loss (RPL). DESIGN Decision analytic model comparing costs and clinical outcomes. SETTING Academic recurrent pregnancy loss programs. PATIENT(S) Women with unexp...

PURPOSE To evaluate the acute effects of laser in situ keratomileusis (LASIK) upon the synthesis of proteoglycans (PGs) and collagen fibril organization in human corneal explants. METHODS Human corneas that had been rejected for transplants were obtained at Banco de Olhos of Hospital São Paulo. For each eye pair, one cornea was submitted to refractive surgery, and the other was used as its ma...
