objective(s):serratia marcescens is one of the nosocomial pathogen. the ability to form biofilm is an important feature in the pathogenesis of s. marcescens. the aim of this study was to determine the anti-adhesive properties of a biosurfactant isolated from lactobacillus acidophilus atcc 4356, on s. marcescens strains. materials and methods: lactobacillus acidophilus atcc 4356, was selected as...
BACKGROUND Traditionally oocytes have been exposed to sperm overnight, for 16-20 h. This long period of co-incubation, however, has been shown to create problems with high levels of reactive oxygen species (ROS), which may affect embryo viability and cause hardening of the zona pellucida. Recently, a positive effect of reducing the co-incubation time to 90-120 min was reported. The objective of...
Background and purpose: Polycyclic aromatic hydrocarbons (PAHs) are a group of environmental pollutants in soils and sediments that causes concern because of their toxic, mutagenic and carcinogenic effects. The purpose of this study was to determine the feasibility of utilizing poultry manure as a co-substrate to enhance the bioremediation of phenanthrene and anthracene in contaminated soil. ...
Probiotic microorganisms have attracted a growing interest for prevention and therapy of gastrointestinal disorders. Many probiotic strains have been shown to inhibit growth and metabolic activity of enteropathogenic bacteria as well as their adhesion and invasion to intestinal cells. In the present study, we evaluated the interference of bacteria-free supernatants (BFS) of cultures belonging t...
The initiation incubation system some decades ago was established to support the start-ups during their initial phase of development. In the current era of information technology and social media, only incubation at one place does not satisfy the needs of the start-ups for co-creating value through innovative solutions. There have been numerous strategies and programs to encourage and support s...
During incubation of chicken embryos, environmental conditions, such as temperature, relative humidity, and CO 2 concentration, must be controlled to meet embryonic requirements that change during the different phases of embryonic development. In the current review, the effects of embryo temperature, egg weight loss, and CO 2 concentration on hatchability, hatchling quality, and subsequent perf...
BACKGROUND Conflicting results have been reported regarding the technique of brief insemination used in IVF. The aim of this meta-analysis was to determine if better clinical outcomes of IVF are associated with a brief co-incubation of gametes than with a standard overnight co-incubation. METHODS A computerized search was conducted of the published literature of four databases, using search ter...
this work examined the simultaneous saccharification and fermentation (ssf) process for the biological conversion rice wastewater into ethanol using co-culture of aspergillus niger (a. niger) and saccharomyces cerevisiae (s. cerevisiae) in batch condition. in this study, the a. niger and s. cerevisiae were used for hydrolysis and production of ethanol from rice wastewater, respectively. the effe...
doxorubicin is a broad spectrum antibiotic used in the treatment of cancers. its dose dependent cardiotoxicity is the most serious side effect causing withdrawal of drug from hard chemotherapeutic regimen. statins are shown to be cytotoxic in concentrations higher than the effective doses for the treatment of hypercholesterolemia (40 mg/day). co-administration of statins and chemotherapeutic ag...
