Vitamin B,, 299 derive their vitamin B,, by absorption of microbially synthesized material from the gut. Carnivorous animals may derive theirs partly in this way and partly from their food. Vitamin B,, has been found in significant amounts in nature only in fermented materials like faeces and in animal products rich in protein. Liver and kidney appear to be the only relatively rich sources and ...

The recently identified gamma-aminobutyric acid type B receptors (GABA(B)Rs) share low sequence similarity with the metabotropic glutamate (mGlu) receptors. Like the mGlu receptors, the N-terminal extracellular domain (NTED) of GABA(B)Rs is proposed to be related to bacterial periplasmic binding proteins (PBPs). However, in contrast to the mGlu receptors, the GABA(B)Rs lack a cysteine-rich regi...

The B cell-specific B29 (Igbeta) gene is activated in the earliest B cell precursors and is expressed throughout B cell development. Tissue-specific expression of the murine B29 gene is controlled by a B cell-specific promoter whose activity is governed by a cassette of upstream transcriptional silencers. This study describes a potent new silencer that is located 5' of the previously identified...

The essential oils of two plants of the genus Bunium called the common name "Zireh" in Persian have been analyzed using GC, GC/MS and 13C NMR spectroscopy. The oils were subjected to antibacterial activity tests. The essential oils have been extracted using hydro-distillation method. The Oils were subjected to analytical GC and GC/MS. The components of the oils were identified using GC retentio...

The concentration of triglyceride-rich lipoproteins containing apolipoprotein (apo) B-48 (chylomicrons) and apo B-100 (very low density lipoproteins) was measured in blood plasma of healthy young men after an ordinary meal containing one-third of daily energy and fat. Plasma obtained in the postabsorptive state and at intervals up to 12 hr after the meal was subjected to immunoaffinity chromato...

conclusions it seems that applying prp is an effective therapeutic approach for wound healing, and faster wound healing is expected due to the presence of more platelets and growth factors. results at the end of study, the prp group showed a greater reduction in the edema ecchymosed discharge approximation (reeda) score compared to the control group (85.5% reduction in the prp group; 72% in the...

background platelet rich plasma is known for its hemostatic, adhesive and healing properties in view of the multiple growth factors released from the platelets to the site of wound. the primary objective of this study was to use autologous platelet rich plasma (prp) in wound beds for anchorage of skin grafts instead of conventional methods like sutures, staplers or glue. methods in a single cen...
