Soluble factors appear to be present in both nuclei and cytoplasm of Krebs 2 ascites tumour cells capable of stimulating the enzyme catalysed methylation of DNA in isolated nuclei from these cells.
Background and objectives: Otostegia persica (Labiatae) is an endemic plant of Iran and is used for its anti-inflammatory properties in folk medicine of Sistan and Baluchestan province. The aim of the present study was to investigate the anti-nociceptive and anti-inflammatory effects of O. Persica different fractions and identification of the natural compounds...
We have analyzed Ca2+ transport activity in defined subcellular fractions of an isogenic set of wild-type and mutant yeast. The results, together with measurements of polypeptide expression levels and promoter::reporter gene activity, show that the Golgi Ca2+-ATPase, Pmr1, is the major Ca2+ pump under normal growth conditions. In the absence of Pmr1, we show a massive, calcineurin-dependent com...
appropriate management of soil phosphorus (p) fertility in highly calcareous soils of iran as around the world should rely upon sound knowledge about the phosphorus reserve and its bioavailability. despite numerous reports on the positive effects of vesicular arbuscular mycorrhizae (vam) fungi on phosphorus uptake which is associated to ectomycorrhiza as a branch of two major branches of group ...
Phosphorus is essential to all forms of life and its contribution towards aiding the native soil fertility sustaining it, well known. With passage time, P added undergoes transformation into various unavailable forms. Native compounds, some being highly insoluble are mostly for plant uptake. The availability phosphorus plants depends on properties, pH, soluble iron, aluminum manganese, calcium ...
Bombyx mori (BM) silk fibroin is composed of two different subunits: heavy chain and light chain fibroin linked by a covalent disulfide bond. Current methods of separating the two silk fractions is complicated and produces inadequate quantities of the isolated components for the study of the individual light and heavy chain silks with respect to new materials. We report a simple method of separ...
