introduction: while little is known about the molecular mechanisms that establish the apical growth patterns in fungal mycelia, recent research on the genetics of a. nidulans and n. crassa has provided considerable amount information on some genes involving in polarised cell growth. a.nidulans is particularly amenable to experimental analysis and is importantly related to other human pathogen f...

transferrin acts as a vehicle for iron transportation between the absorption, storage and utilization sites in the body and, besides iron, its two highaffinity iron-binding site are capable of binding to 29 other elements. in physiological and pathophysiological conditions, transferrin’s properties are different and close attention to these properties is required. for further investigation for ...

in west africa and nigeria in particular, many virgin plants are still waiting to be evaluated for their medicinal importance. claims of plants with folk medicinal applications need to be evaluated and verified. gomphrena celosioides (family – amaranthaceae) is a weed grown in lawns and the biological activity of the extract had earlier been established. in the present study, the plant was coll...

background kelussia odoratissima mozaff. is one of the newest genera of umbelliferae which is represented by only one species. this sweet-smelling, self-growing monotypic medicinal plant is endemic to a restricted area in west of iran and is locally called karafse-koohi. the aerial parts of the plant are commonly used as a popular garnish and a sedative medicinal plant. there are several report...

A highly efficient, simple and clean solvent-free protocol for the synthesis of polyhydroquinolines is described. The one-pot multi-component condensation reaction between arylaldehydes, dimedone (5,5-dimethylcyclohexane-1,3-dione), β-ketoesters and ammonium acetate in the presence of catalytic amount of (2.5 mol%) melamine trisulfonic acid (MTSA) as a recyclable, green and attractive sulfonic ...

isolation of pigmented t.violaceum from a patient with endothrix infection associated with the inflammatory and kerion symptoms and also isolation of the non- pigmented strain from another patient with non-inflammatory symptoms, led us to investigate the enzymic activities in both strains. most of the studies on dermatophyte compoxition have shown the relationship between proteolytic enzymes an...

herpes simplex virus types 1 (hsv-1) and 2 (hsv-2) are members of the herpesviridae family. about 40% to 80% of the world populations are infected with hsv and its prevalence is high in iran. the high prevalence of this virus in the community and the ability of the virus in causing fatal diseases among immunocompromised patients, have encouraged studies to be performed on hsv and suitable cell ...
