in the turfgrass industry, the need for salinity tolerant turfgrasses is increasing because of the increased use of saline and non-potable water. greenhouse container experiments were conducted to determine the relative salinity tolerance and growth responses of eleven native populations of tall fescue (festuca arundinacea schrub) (tf), including: semirom, mashhad, sanandaj, yasuj, yazd abad, d...

Phytochemical investigation of the above-ground biomass of Asclepias sullivantii L. (Asclepiadaceae) afforded six new pregnane glycosides, named sullivantosides A-F (1–6). The structures of 1–6 were elucidated through a variety of spectroscopic and spectrometric techniques (1D and 2D NMR; HRESIMS). To the best of our knowledge, this work represents the first phytochemical study of this species....
Cancer patients often have an activated clotting system and are at increased risk for venous thrombosis. In the present study, we analyzed tissue factor (TF) expression in 4 different human pancreatic tumor cell lines for the purpose of producing derivative tumors in vivo. We found that 2 of the lines expressed TF and released TF-positive microparticles (MPs) into the culture medium. The majori...
Tissue factor (TF) is an integral membrane glycoprotein which, as the receptor and essential cofactor for coagulation factors VII and VIIa (FVII and FVIIa, respectively), is the primary cellular activator of the coagulation protease cascade. Previous studies on the procoagulant activity of a variety of cell types (either lysed or in the intact state) have variously been interpreted as showing t...
An expression construct harboring granulocyte colony-stimulating factor (G-CSF)-transferrin (Tf) fusion protein (G-CSF-Tf) was engineered by fusing human cDNAs encoding G-CSF and Tf to explore the feasibility of using Tf as a carrier moiety for oral delivery of therapeutic proteins. The recombinant protein, G-CSF-Tf, was harvested from protein-free, conditioned medium of transfected HEK293 cell...
sericostoma pauciflorum stocks ex wight(family boraginaceae) used against cancer, diabetes and known to be health promoter. callus cultures have been established from the stem explants on murashige and skoog (ms) medium supplemented with 1.5 mg/l concentration of different growth hormone viz. kinetin (kn), indole 3-acetic acid (iaa) and indole 3-butyric acid (iba). at 6 weeks of age, these call...
We present a detailed analysis, based on the forward flux sampling simulation method, of the switching dynamics and stability of two models of genetic toggle switches, consisting of two mutually repressing genes encoding transcription factors (TFs); in one model (the exclusive switch), the two transcription factors mutually exclude each other's binding, while in the other model (general switch)...
In this study the uptake of tissue factor (TF)-positive microparticles by endothelial cells and the recycling of the TF component were examined. Human dermal blood endothelial cells (HDBEC) were incubated with microparticles derived from cancer cell lines for up to 6 hours. Measurement of HDBEC cell surface TF antigen revealed two distinct peaks at 30 and 180-240 minutes post-incubation with TF...
چکید ه سابقه و هدف فاکتور بافتی( tf )، اصلی ترین آغازکننده آبشار انعقادی است. برای بررسی مسیر خارجی انعقاد، اندازه گیری زمان پروترومبین بهترین روش است که در این روش با توجه به tf به کار گرفته شده، نوساناتی در نتیجه آزمایش دیده می شود. در این مطالعه با هدف دستیابی به نتایجی با تکرارپذیری بیشتر، از tf نوترکیب استفاده شده است. مواد و روش ها مطالعه انجام شده از نوع تجربی بود. cdna فاکتور با...
