Abstract Introduction Testis microenvironment which is comprised of cells like Sertoli and peritubular releases paracrine factors could potentially modulate testicular functions. In our previous studies, we identified Leptin as a key factor in the microenvironment, released by goes to bind its receptor Leydig cells. Once this association happens it further induces expression desert hedgehog sig...

Although manganese (Mn) is an essential trace element for human development and growth, chronic exposure to excessive Mn levels can result in psychiatric and motor disturbances, referred to as manganism. However, there are no known mechanism(s) for efflux of excess Mn from mammalian cells. Here, we test the hypothesis that the cytoplasmic iron (Fe) exporter ferroportin (Fpn) may also function a...

An experiment was conducted to estimate the relative biological availability of manganese (Mn) from some inorganic sources compared with that from reagent grade Mn sulfate. Three hundred developed local strain "Golden Montazah" male chicks 4 weeks old were used. They were randomly distributed into 10 groups (3 replicates / group) (10 male chicks / replicate) according to the average replicate b...

in order to evaluate the effect of foliar application of micro nutrients on physiological growth indices and total dry matter yield of forage corn. field experiment was conducted in 2006 at bersian village isfahan. a randomized complete block design with four replications was used. plant treated with 8 foliar application treatments (fe, zn, cu, mn, fe + mn, cu + zn, fe + mn + cu + zn and contro...

the direct conversion of methane to c2 hydrocarbons, in a quartz tube reactor enforced by a dc corona discharge, was investigated at atmospheric pressure. the process was carried out in the presence of metal oxide catalysts of mn/w/sio2, mn/w/sio2 (tetraethyl orthosilicate, teos), and mn/w/cnt (supported on carbon nanotubes). the total yield to c2 hydrocarbons in the presence of metal oxide cat...

The use of phenyl-2-pyridyl ketone oxime and di-2-pyridyl ketone oxime in Mn chemistry has led to hexanuclear clusters with unprecedented (Mn(II)(4)Mn(III)Mn(IV)) or extremely rare (Mn(II)Mn(III)(5) and Mn(II)(3)Mn(III)(3)) metal oxidation-state combinations and uncommon structural motifs.

Manganese (Mn) oxides are among the most reactive sorbents and oxidants within the environment, where they play a central role in the cycling of nutrients, metals, and carbon. Recent discoveries have identified superoxide ([Formula: see text]) both of biogenic and abiogenic origin as an effective oxidant of Mn(II) leading to the formation of Mn oxides. Here we examined the conditions under whic...

Introduction: Median nerve (MN), one of terminal branches of brachial plexus, is commonly associated with several variations. This research aimed to review the literature related to the variations of MN from axillary region to cubital fossa. Methods: We searched Google Scholar, Science Direct, Springer, and PubMed electronic databases to compile reports related to the variation of MN published...
