Presence of CRISPR CAS-Like Sequences as a Proposed Mechanism for Horizontal Genetic Exchanges between Trichomonas vaginalis and Its Associated Virus: A Comparative Genomic Analysis with the First Report of a Putative CRISPR CAS Structures in Eukaryotic Cells.

Introduction: Trichomonas vaginalis genome is among the largest genome size and coding capacities. Combinations of gene duplications, transposon, repeated sequences, and lateral gene transfers (LGTs) have contributed to the unexpected large genomic size and diversity. This study is aimed at investigating genomic exchange and seeking for presence of the CRISPR CAS system as one of the possible mechanisms for some level of genetic exchange.

Potential Role of Lactobacillus and Bifidobacterium for Preventing Kidney Stones.

Background: A probiotic is a living microorganism that promotes host health when grown under appropriate conditions. Kidney stones are one of the universal agonizing diseases that have increased dramatically in recent years. One of the causes of this disease is hyperoxaluria (HOU), which is known to be an important factor in the formation of oxalate stones and is manifested by high levels of oxalate in the urine.

Synthesis and optimization of emission characteristics of water-dispersible ag-in-s quantum dots and their bactericidal activity.

Developing novel aqueous-soluble quantum dots (QDs) can create new opportunities for better biological utilization. In the present work, novel, high emissive and biocompatible N-acetyl-L-cysteine-capped Ag-In-S QDs (as an I-III-VI structure) were prepared in a facile and straightforward way. The dominance of the strong confinement regime was observed due to the very small size of nanoparticles, which was smaller than their excitonic Bohr radius.

Aqueous-based synthesis of Cd-free and highly emissive Fe-doped ZnSe(S)/ZnSe(S) core/shell quantum dots with antibacterial activity.

The effective insertion of intentional impurities in direct aqueous preparation of doped QDs still needs a chemical route with well-designed strategy. The present work reports a facile, one-pot, and aqueous-based method for green synthesis of Fe-doped ZnSe(S)/ZnSe(S) core/shell QDs with improved emission intensity. In the proposed strategy, by using a sulfur rich ZnSe(S) shell, we can provide a wider band gap shell with low structural defects in the interface between core and shell.

Anti-biofilm Properties of Peganum harmala against Candida albicans.

Objectives: Vaginitis still remains as a health issue in women. It is notable that Candida albicans producing biofilm is considered a microorganism responsible for vaginitis with hard to treat. Also, Peganum harmala was applied as an anti fungal in treatment for many infections in Iran.

Antioxidant activity of different parts of Pistacia khinjuk Stocks fruit and its correlation to phenolic composition.

The fruits of Pistacia khinjuk Stocks were collected from Ilam province, Iran. The aim of this study was to analyse antioxidant capacity and phenolic composition of different parts of P. khinjuk fruit.

Antioxidant capacity and phenolic composition of leaves from 10 Bene (Pistacia atlantica subsp. kurdica) genotypes.

Leaves of 10 Bene genotypes were collected from six provinces (West Azerbaijan, Kurdistan, Kermanshah, Ilam, Hamedan and Lorestan) in Iran. This study was carried out to better characterise the total phenolic and flavonoid contents, antioxidant capacity and phenolic composition, as well as to evaluate the correlation between content of phenolic compounds and antioxidant activity in 10 genotypes of Bene. The antioxidant activity of leaf extracts was measured using different assays: ferric reducing antioxidant power, nitric oxide radical scavenging and 2,2-diphenyl-1-picrylhydrazyl.
