conclusions this study shows that bdnf and ngf expression decreases in diabetic neuropathy. however, this decrease can be reversed through endurance training. these results also indicate that endurance training may have a potential role in compensating for neurotrophin deficiency following diabetic neuropathy. objectives this experimental study was designed and carried out at the tarbiat modare...

the low bioavailability of zinc (zn) is in calcareous and saline soil, therefore the study of chemical forms and bioavailability of zn in these soils is necessary to estimate the potential availability. the objective of this study was to evaluate the effect of plant growth promoting rhizobacteria and mycorrhizae fungi inoculation on the chemical forms of zn in a calcareous soil at different sal...

The elucidation of the structure of pteroylglutamic acid (PGA) (Lactobacillus casei factor, vitamin B,) has shown that p-aminobenzoic acid (PABA) is a component of the PGA molecule (1). Since earlier work has treated PABA and PGA as distinct growth factors for bacteria (2), it is now necessary to study the relationship in the utilization of these substances by bacteria. It has been shown that m...

objective high concentration of iron and other trace elements could restrict bacterial growth and modify their metabolic pattern as well. however, this study aimed to find out the influence of iron, chromium, cadmium and synergism or antagonism between these elements on the growth of a gram positive bacterium. materials and methods in a series of experiments, bucillus cereus was cultured in a n...

Several hemopoietic growth factors have now been purified, cloned, and produced in bacteria. Granulocyte colony stimulating factor and granulocyte-macrophage colony stimulating factor are already being used in clinical trials. Within 12 months two more hemopoietic growth factors, macrophage colony stimulating factor (also called colony stimulating factor 1) and interleukin 3 (also called multi-...

Peptidoglycan recognition protein (PGRP) is conserved from insects to mammals. In insects, PGRP recognizes bacterial cell wall peptidoglycan (PGN) and activates prophenoloxidase cascade, a part of the insect antimicrobial defense system. Because mammals do not have the prophenoloxidase cascade, its function in mammals is unknown. However, it was suggested that an identical protein (Tag7) was a ...

background :    due to excessive consumption of synthetic drugs, drug resistance rate of pathogenic bacteria is increasing and there is an ever-increasing need to find new safe compounds to tackle this problem. this study was conducted to investigate the consequences of chavill extract on the growth and viability of gastrointestinal pathogenic bacterium and probiotics bacteria.   methods :    t...

background and objectives: to find antagonistic bacteria with potential antifungal activity against some pathogenic fungi, including aspergillus niger , a. flavus, fusarium moniliforme and penicillium marneffei , a total of 148 agricultural soil samples from different sites of tehran were examined.  materials and methods: antagonistic soils were selected by screening against a. niger on glucose...

Wound healing proceeds by a number of (partially) overlapping steps: bleeding, blood clotting, removal of contaminants and bacteria, wound closure by cell mitosis and migration towards the wound center, repair of the vascular network, and wound contraction along lines of equal tension. We consider a model due to Adam [1] for the closure of a wound. The model is based on an epidermal growth fact...
