Shortening the sulfur cell cycle by a green approach for bio-production of extracellular metalloid-sulfide nanoparticles.

In the present study, a new approach was introduced regarding the extracellular synthesis of selenium sulfide micro/nano-particles using Saccharomyces cerevisiae in different ammonium sulfate supplementation and in the presence of sodium selenosulfate precursors (S) and a blend of selenous acid and sodium sulfite (S). In S, only cell supernatant exposed to ammonium sulfate was able to reduce sodium selenosulfate. Whereas, in S, cell supernatant in both pre-conditions of with or without ammonium sulfate (S + or S-) were able to reduce selenous acid and sodium sulfite.

Recombinant urate oxidase (UOX, E.C.1.

: From Taxonomy to Biotechnological and Industrial Perspectives.

For a long time, the genus has been known and considered among the most applicable genera in several fields. Recent taxonomical developments resulted in the identification of more species in -related genera, particularly in the order (earlier heterotypic synonym: ), with potential application for biotechnological and industrial purposes such as biofuels, bioactive agents, biopolymers, and enzymes. Therefore, a thorough understanding of the taxonomy, growth requirements and physiology, genomics, and metabolic pathways in the highly diverse bacterial order, , will facilitate a more robust designing and sustainable production of strain lines relevant to a circular economy.

Interaction between Clostridium species and microbiota to progress immune regulation.

Gut microbiota can interact with the immune system through direct or indirect pathways. In the indirect pathway, gut microbiota produces metabolites such as short chain fatty acids (SCFAs), which may modulate the immune response. SCFAs reduce inflammation, repair intestinal barrier, and induce propagation of specific immune cells, e.

Microbiological insights into anaerobic digestion for biogas, hydrogen or volatile fatty acids (VFAs): a review.

In the past decades, considerable attention has been directed toward anaerobic digestion (AD), which is an effective biological process for converting diverse organic wastes into biogas, volatile fatty acids (VFAs), biohydrogen, etc. The microbial bioprocessing takes part during AD is of substantial significance, and one of the crucial approaches for the deep and adequate understanding and manipulating it toward different products is process microbiology. Due to highly complexity of AD microbiome, it is critically important to study the involved microorganisms in AD.

Effects of and on serotonin transporter expression in intestinal epithelial cells.

Purpose: The highest level of peripheral serotonin in the body can be found in the gastrointestinal (GI) tract as its reservoir. There is complete interaction between human gastrointestinal microbiota and serotonin system. Serotonin in the GI is transferred by serotonin transporters (SERTs), which play a crucial role in the bioavailability of serotonin in the GI.

Effect of Akkermansia muciniphila, Faecalibacterium prausnitzii, and Their Extracellular Vesicles on the Serotonin System in Intestinal Epithelial Cells.

The gastrointestinal (GI) tract is an essential reservoir of serotonin or 5-hydroxytryptamine (5-HT), which possesses a set of bacterial species communities. Intestinal microbiota has the ability to modulate the host's serotonin system. In this regard, we evaluated the effect of Akkermansia muciniphila and Faecalibacterium prausnitzii along with their extracellular vesicles (EVs) on serotonin system-related genes in human epithelial colorectal adenocarcinoma (Caco-2) cells.

Studies in lung cancer cytokine proteomics: a review.

Introduction: Proteins are molecules that have role in the progression of the diseases. Proteomics is a tool that can play an effective role in identifying diagnostic and therapeutic biomarkers for lung cancer. Cytokines are proteins that play a decisive role in activating body's immune system in lung cancer.

Modulation of serotonin signaling/metabolism by Akkermansia muciniphila and its extracellular vesicles through the gut-brain axis in mice.

Several studies have reported that the host-microbe interactions in the gut modulate the host serotonin or 5-hydroxytryptamine (5-HT) system. Here, we evaluated the effects of Akkermansia muciniphila and its extracellular vesicles (EVs) on genes pertaining to the serotonergic system in the colon and hippocampus of mice. Male C57BL/6J mice were administered viable A.

Computational Approach for Rational Design of Fusion Uricase with PAS Sequences.

Tumor lysis syndrome is a life-threatening condition for humans due to the lack of urate oxidase. In this study, several variants of PASylated uricase from the species were analyzed computationally to find the appropriate fusions to solve short half-life and stability concern. The method was performed using Rosetta software to structurally characterize the PAS sequences.

The study aimed to evaluate the increasing trend in global ranking of Iranian medical universities websites emphasizing on comparative approach.

Species spectrum of nontuberculous mycobacteria isolated from suspected tuberculosis patients, identification by multi locus sequence analysis.

Identification of Mycobacterium species is difficult due to a complex and rapidly changing taxonomy, the failure of 16S rRNA to discriminate many closely related species and the unreliability of phenotypic testing. We investigated a collection of nontuberculous mycobacteria (NTM) strains isolated from suspected tuberculosis patients at Tuberculosis Reference Centre (Ahvaz, Iran) and Masoud Laboratory (Tehran, Iran) during 2008-2012 to evaluate the species spectrum of NTM isolates. Based on phenotypic tests, the isolates were identified up to species or complex level; however they were heterogonous by hsp65-PCR restriction fragment length polymorphism analysis (PRA) method.
