We have studied trehalose uptake in Salmonella typhimurium and the possible involvement of the phosphoenolpyruvate:carbohydrate phosphotransferase system (PTS) in this process. Two transport systems could recognize and transport trehalose, the mannose PTS and the galactose permease. Uptake of trehalose via the latter system required that it be expressed constitutively (due to a galR or galC mut...

The objective of this study was to evaluate the importance of environmental and genetic factors affecting semen quality; sperm volume (SV), sperm concentration (SPCO), total sperm (TS), fresh sperm motility (FSM), total fresh motile sperm (TFMS), post thaw sperm motility (PTSM), total post thaw motile sperm (TPTMS), number of produced payout (NPP), number of fresh motile sperm in each milt ejac...

the production and application of pet tracers has been a unique step in the progress of nuclear medicine in last two decades. the most important pet tracers include f-18, c-11 and n-13 radioisotopes and many nuclear medicine centers throughout the globe are using them. however some new tracers are under their way to the mass administration, currently being in the clinical trials or preliminary ...
