The gram-positive bacterium Bacillus subtilis contains two minimal Tat translocases, TatAdCd and TatAyCy, which are each involved in the secretion of one or more specific protein substrates. We have investigated the subcellular localization of the TatA components by employing C-terminal green fluorescent protein (GFP) fusions and fluorescence microscopy. When expressed from a xylose-inducible p...

Sea-blue histiocytosis is a rare disorder seen in patients with lipid metabolic or ceroid storage diseases. Sea-blue histiocytes are ceroid-laden macrophages detectable by May-Giemsa staining. We report a case of a 28-year-old woman diagnosed with Niemann-Pick disease at 2 or 3 years of age. To confirm this diagnosis, we examined her bone marrow, which revealed scattered foci containing aggrega...

this study was conducted in khorasan-razavi during 23 months (since february 2004 to december 2005). the samples (83 samples) of suspected farms were collected from tongue and mouth epithelium and tested by indirect sandwich elisa and rt-pcr. during the study, twelve foci during the year 2004 and 23 foci during the year 2005 (up to december) were approved. maximum distribution of fmd foci was o...

BACKGROUND The present study was conducted in order to evaluate the effects of bilateral uterine artery ligation (BUAL) on the ovarian follicular fate, and alterations in carbohydrate, lipid, lipase and serum levels of F9SH, LH, prolactin, estrogen and progesterone. METHODS Twenty-four mature female rabbits divided into two test and control-sham groups. The animals underwent ovariohystrectomy...

Barbel (Barbus bocagei) a common species in Portuguese rivers was studied to assess the impact of water contamination on hepatic oxidative stress response, lipid peroxidation and histology. The Vizela River is a tributary of the Ave River, located in one of the most industrialized areas of Portugal. The oxidative stress biomarkers analyzed included superoxide dismutase, catalase, glutathione S-...
