In this work, we analyzed the community structure and metabolic potential of sediment microbial communities in high-latitude coastal environments subjected to low to moderate levels of chronic pollution. Subtidal sediments from four low-energy inlets located in polar and subpolar regions from both Hemispheres were analyzed using large-scale 16S rRNA gene and metagenomic sequencing. Communities showed high diversity (Shannon's index 6.8 to 10.2), with distinct phylogenetic structures (<40% shared taxa at the Phylum level among regions) but similar metabolic potential in terms of sequences assigned to KOs...

The purpose of this study was to evaluate the utility of a breast cancer risk assessment (BCRA) at the time of screening mammogram. Women whose BCRA indicated a high risk for cancer received a letter with instructions for breast health care and genetic counseling if appropriate. After 6 months this group received surveys to evaluate their risk perception and their recall of, and compliance with, recommendations. We also explored the impact of other variables such as a recommendation for genetic counseling and physician communication with the women...

Bacitracins are mixtures of structurally related cyclic polypeptides with antibiotic properties. They act by interfering with the biosynthesis of the bacterial cell wall. In this study, we analyzed an avian necrotic enteritis strain of Clostridium perfringens that was resistant to bacitracin and produced NetB toxin. We identified a bacitracin resistance locus that resembled a bacitracin resistance determinant from Enterococcus faecalis. It contained the structural genes bcrABD and a putative regulatory gene, bcrR...

Most of the first generation of anticancer drugs act by preventing cellular proliferation. The fact that can induce remissions in the tumour without lethal toxicity to the patient is, at first sight, surprising. However anti-proliferative agents have been the mainstay of cancer treatment for 60 years and continue to play a major role. Perhaps we should view their lack of toxicities to non-proliferating tissues as an advantage rather than seeing only that their toxicity to proliferating tissues is a problem...

Aiming to efficiently dispose printing and dyeing wastewater with "high organic nitrogen and aromatic compounds, but low carbon source quality", the reinforced anaerobic hydrolysis-denitrification coupling process, based on improved UASB reactors and segregated collection-disposition strategy, was designed and applied at the pilot scale. Results showed that the coupling process displayed efficient removal for these two kinds of pollutants (nitrogen and aromatics), since the concentration of NH3-N (shortened as ρ (NH3-N)) < 8 mg/L, ρ (TN) < 15 mg/L with long-term stability for the effluent, and both species and abundances of aromatics reduced greatly by UASBs according to GC-MS...

Borderline ovarian tumours differ from epithelial ovarian cancer by their low incidence, frequent association with infertility, low association with mutations in BCRA genes, different percentages of the most common histological types, early stage diagnosis, and high survival rate, even when associated with peritoneal involvement. They occur in younger women, which is why one of the objectives in these patients will be the preservation of fertility. The management of these tumours has been widely discussed and still continues to be controversial...

Bacillus spp. are widely used as feed additives and probiotics. However, there is limited information on their resistance to various antibiotics, and there is a growing concern over the transfer of antibiotic resistance genes. The MIC for 8 antibiotics was determined for 85 Bacillus species strains, Bacillus subtilis subsp. subtilis (n = 29), Bacillus licheniformis (n = 38), and Bacillus sonorensis (n = 18), all of which were isolated from starters for Sudanese bread production. All the strains were sensitive to tetracycline (8...

This study was conducted to characterize the antimicrobial resistance determinants and investigate plasmid colocalization of tetracycline and macrolide genes in Enterococcus faecalis and Enterococcus faecium from broiler chicken and turkey flocks in Canada. A total of 387 E. faecalis and E. faecium isolates were recovered from poultry cecal contents from five processing plants. The percentages of resistant E. faecalis and E. faecium isolates, respectively, were 88.1 and 94% to bacitracin, 0 and 0.9% to chloramphenicol, 0...

The GntR-like protein NorG has been shown to affect Staphylococcus aureus genes involved in resistance to quinolones and β-lactams, such as those encoding the NorB and AbcA transporters. To identify the target genes regulated by NorG, we carried out transcriptional-profiling assays using S. aureus RN6390 and its isogenic norG::cat mutant. Our data showed that NorG positively affected the transcription of global regulators mgrA, arlS, and sarZ. The three putative drug efflux pump genes most positively affected by NorG were the NorB efflux pump (5...

Oncogenetic consultations and predictive BRCA1/2 testing are intertwined processes and the specific impact of these genetic tests if performed alone through direct-to-consumer offers remains unknown. Noteworthy, the expectations of patients vary with their own status, whether they are affected or not by breast cancer at the time genetic testing is performed. The prescription of genetic tests for BCRA mutations has doubled in France between 2003 and 2009. There is a consensus on the fact that genetic results disclosure led to a significant increase in the knowledge and understanding that the patients have of the genetic risk and also changed the medical follow-up of these patients...

OBJECTIVE: In order to study the diversity and distribution of Benzoyl coenzyme A reductase (bcrA) and oxygenase components of 1H-2-oxoquinoline 8-monooxygenase (oxoO) gene in a lab scale denitrifying bioreactors for treating quinoline-containing wastewater. METHODS: Genomic microbial DNA was extracted from the biofilm samples of bioreactor. Based on the known oxoO genes sequences in GenBank, we designed primers for oxoO gene amplification. Using our designed oxoO gene primers and a pair of degenerate primers of bcrA gene obtained from literature, we amplified the DNA samples...

INTRODUCTION: Precancerous ovarian epithelial dysplasia was first described after prophylactic oophorectomy (OP) for genetic risk (BRCA mutation) or because of a strong family history of ovarian and/or breast cancer. The objective of this study was to describe histopathological features of ovarian dysplasia and to propose a dysplasia scoring sheme with a cut-off. PATIENTS AND METHOD: One hundred and twenty-five bilateral oophorectomies (genetic predisposition: n=35 and control group: n=90) were reviewed by two pathologists blinded to clinical data...

The events leading to the most common and most lethal ovarian carcinoma - high grade serous carcinoma - have been poorly understood. However, the detailed pathologic study of asymptomatic women with germ-line BRCA 1 or BRCA2 (BCRA+) mutations has unearthed an early malignancy, serous tubal intraepithelial carcinomas (STIC), which has linked many peritoneal and ovarian serous carcinomas to the fimbria. The distinction between high-grade serous and endometrioid carcinomas continues to narrow, with shared alterations in expression of pTEN, PAX2 and p53...

Few membrane proteins with a role in transcriptional regulation have been studied, and none are able to perceive their respective stimuli and activate transcription of their regulons without the aid of auxiliary proteins. The bacitracin resistance regulator, BcrR, of Enterococcus faecalis is a membrane-bound DNA binding protein and is required for bacitracin-dependent expression of the bacitracin resistance genes, bcrABD. Here, we show that BcrR interacts directly with Zn2+ bacitracin (Kd = 2-5 micropM), but not metal-free bacitracin...

OBJECTIVE: Erectile dysfunction (ED) following radical prostatectomy is of major concern for both patients and caring physicians. We evaluated the bulbocavernosus reflex latency (BCRL) and amplitude (BCRA) following bilateral nerve-sparing radical retropubic prostatectomy (NS-RRP) to predict the response to sildenafil citrate (SC). METHODS: Patients were recruited in our ED clinic following NS-RRP. Exclusion criteria included preoperative significant ED, neurological disease, and nitrates treatment...
