despite recent innovations in the laboratory diagnosis of bacterial from nonbacterial meningitis, solid data-necessary for early determination of bacterial meningitis (bm) before organism growth in the culture medium-are missing. therefore cerebrospinal fluid (csf) lactate levels were evaluated as a possible means of differentiating the two clinical entities. this was a retrospective study. pat...

Disease suppressive soils are important for managing soil-borne diseases that cannot be controlled with chemicals. One such disease is the potato common scab caused by Streptomyces species. Suppressiveness against can develop spontaneously in fields where grown years without interruption, and this has been attributed to non-pathogenic strains. spp. have used as inoculants biological control, bu...

Several fecal and enteric pathogens are present within the primary organic raw materials that introduced to compost piles. These may compete with existing microbiota limit their efficiency, yielding only partial decomposition of final compost. also affect process kinetics persist in or even regrow as a result declining effect indigenous antagonistic micro-organisms. In this work, 11 bacterial i...

A search for active bacterial growth inhibitors among seven highly potent morphine-like narcotics revealed that NIH 7591 and etorphine inhibited the rates of growth of Escherichia coli by 50% at 1.9 x 10(-4) M. Bacterial cultures escaped from growth inhibition by NIH 7591 after times which were proportional to the drug concentrations and inversely proportional to the initial bacterial densities...

Voltage-gated sodium channels (NaVs) are activated by transiting the voltage sensor from the deactivated to the activated state. The crystal structures of several bacterial NaVs have captured the voltage sensor module (VSM) in an activated state, but structure of the deactivated voltage sensor remains elusive. In this study, we sought to identify peptide toxins stabilizing the deactivated VSM o...

Background: General concern is that the pregnancy rate is higher with GnRH-agonist as a protocol of pituitary suppression. GnRH-antagonist protocol provides a shorter period of administration and an easy flexible protocol. In this study, the outcomes of GnRH agonist and antagonist in ICSI cycles are compared in normo responder patients. Materials and Methods: In this randomized clinical trial, ...

objective: this study was conducted to compare the results of fixed versus flexible gnrh antagonist protocols in controlled ovarian stimulation for intra cytoplasmic sperm injection (icsi) in patients with pcos. materials and methods: a randomized clinical trial was performed on 100 pcos women, who were admitted to a tertiary infertility clinic and were candidate for ivf/icsi. they were divided...

the aim of the present study was to investigate whether and by which mechanism; histamine can induce state-dependent retrieval of passive avoidance task. the pre-training or pre-test intracerebroventricular (i.c.v.) injection of histamine (20µg/mouse) impaired retrieval, when it was tested 24 h later. in the animals, which retrieval was impaired due to histamine pre-training administration, pre...

background and objective: host genetic factors such as cytokine gene polymorphisms as well as helicobacter pylori (h. pylori) infection have been found to be associated with gastric cancer risk . interleukin 1 is a pro-inflammatory cytokine involved in h. pylori-induced gastric inflammation. therefore, we analyzed the association between il-1β and il-1-rn polymorphisms and gastric cancer in per...

The development of multi-drug-resistant bacteria pushed the scientific community to look for new alternatives solve problem. Propolis is a beehive substance and one richest natural products in bioactive compounds with antibacterial activity. This study was aimed investigate possible synergistic interaction between propolis drugs, such as essential oils (EOs) antibiotics, order find increased ac...
