AIM: To describe the technique of a modified extraperitoneal retrotransversalis end colostomy as part of a laparoscopic abdomino-perineal resection (APR). METHOD: The colostomy site is preoperatively chosen and intraoperatively used for a trocar. After the rectum has been mobilized the descending colon is freed. The peritoneal margin is gently grasped and the parietal peritoneum, extraperitoneal together with the transversalis fascia are separated from the transverse abdominal muscle fibres upwards for 3-4 cm aiming at the trocar site to form the extraperitoneal retrotransversalis canal...

The aim of this study was to estimate virulence potential of Salmonella enterica strains colonizing the gut of free-living sand lizards (Lacerta agilis L.). The strains belonged to three Salmonella serovars: Abony, Schleissheim, and Telhashomer. Adhesion and invasion abilities of the strains were determined in quantitative assays using the gentamicin protection method. Induction of apoptosis was assessed using HeLa cell monolayers. PCR assays were used for detection of 26 virulence genes localised within mobile elements: pathogenicity islands, virulence plasmids, and prophage sequences...

BACKGROUND: Usefulness of a mobile monitoring system for Crohn's disease (CD) has not been evaluated. We aimed to determine whether disease activity patterns depicted using a web-based symptom diary for CD could indicate disease clinical outcomes. METHODS: Patients with CD from tertiary hospitals were prospectively invited to record their symptoms using a smartphone at least once a week. Disease activity patterns for at least 2 months were statistically classified into good and poor groups based on two factors in two consecutive time frames; the degree of score variation (maximum-minimum) in each frame and the trend (upward, stationary, or downward) of patterns indicated by the difference in the mean activity scores between two time frames...

Androgens play a vital role in prostate cancer development, and their elimination and blockade are essential in the disease management. DHT is the key ligand for androgen receptor (AR) in the prostate. It is locally synthesized from testosterone. In the prostate, DHT is predominantly metabolized to α-diol and β-diol. Recent studies indicate that impaired DHT catabolism is associated with prostate cancer, signifying the necessity of a sensitive quantitative method for the determination of DHT and its metabolites...

Implants decorated with antimicrobial peptides (AMPs) can prevent infection and reduce the risk of creating antibiotic resistance. Yet the restricted mobility of surficial AMP often compromises its activity. Here, we report a simple but effective strategy to allow a more flexible display of AMP on the biomaterial surface and demonstrate its efficacy for wound healing. The AMP, tachyplesin I (Tac), is tagged with the polyhydroxyalkanoate-granule-associated protein (PhaP) and immobilized on haloarchaea-produced poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV) via hydrophobic interaction...

BACKGROUND: Cervical cancer is a preventable disease. Unfortunately, its mortality is high in Hungary: 9.2 deaths /100000 women/year in 2015. The Hungarian organized, nationwide cervical screening program was launched in 2003, but it could improve the coverage rate of cervical cancer screening only by a few percentage points. The vast majority of women still uses opportunistic screening and the organized screening program had little impact on participation by women who never or rarely consult their gynecologists...

Substantial increase in level of particulate matter has raised concerns in South Korea recently. Ambient particulate matter is classified as Group I carcinogen (IARC, 2013) and multiple epidemiological studies has demonstrated adverse health effects due to exposure of particulate matter. Fine particulate matter (PM2.5 ) which has a diameter <2.5 μm is likely to penetrate deeply into lung and is known to be eliciting adverse health effects. A number of epidemiological studies have been conducted on adverse health effects of PM-related diseases and mortality rate, yet particulate matter (PM)-induced reactive oxygen species (ROS) activity at the cellular level has not been actively studied in Korea...

BACKGROUND: Treatment for fractures of the tibial plateau is in most cases carried out by stable fixation in order to allow early mobilization. Minimally invasive technologies such as tibioplasty or stabilization by locking plate, bone augmentation and cement filling (CF) have recently been used to treat this type of fracture. The aim of this paper was to determine the mechanical behavior of the tibial plateau by numerically modeling and by quantifying the mechanical effects on the tibia mechanical properties from injury healing...

Close-to-community (CTC) providers have been identified as a key cadre to progress universal health coverage and address inequities in health service provision due to their embedded position within communities. CTC providers both work within, and are subject to, the gender norms at community level but may also have the potential to alter them. This paper synthesises current evidence on gender and CTC providers and the services they deliver. This study uses a two-stage exploratory approach drawing upon qualitative research from the six countries (Bangladesh, Indonesia, Ethiopia, Kenya, Malawi, Mozambique) that were part of the REACHOUT consortium...

Idiopathic hypogonadotropic hypogonadism (IHH) is characterized by low levels of gonadotropins and delayed or absent sexual development. Most of the patients are diagnosed in late adolescence or early adulthood. Determining the diagnosis of IHH in prepubertal patients can be challenging. Making a timely, correct diagnosis has important clinical implications. Here we aimed to identify the genetic cause of IHH in three prepubertal siblings from a Chinese Han family and give appropriate treatment advice. Using whole exome sequencing (WES), we identified a novel homozygous GNRHR mutation (NM_000406; c...

OBJECTIVE: The anatomy of the perineum and the pelvic diaphragm of woman is complex. A numerical complete three-dimensional (3D) model of every muscle of the woman pelvis doesn't exist. The pathophysiology of genital prolapse is still debated. Knowledge of anatomy is essential to better understand its mechanisms. The aim of this research was to build a complete three-dimensional model of the female perineum and pelvic floor muscles. STUDY DESIGN: To model the pelvic muscles we reconstructed them in three dimensions from tracing a magnetic resonance imaging (MRI) of a female pelvis from a cadaver...

We present our experience with five patients with CLTI treated with distal revascularization and omental flap coverage. We decided to investigate the efficacy and safety of NPWT (negative-pressure wound therapy) in promoting the fixation and remodeling of the omental flap as there is some evidence in the literature about the optimization of results for skin graft and dermal substitutes. Surgical revascularization was always the first procedure attempted; wound coverage was realized 3-5 days after the primary procedure (omental free-flap in three patients and omental flow-through flap in two patients)...

High mobility group box-1 (HMGB1) acts as a proinflammatory molecule once released into the extracellular space and inhibition of HMGB1 signaling has been reported be neuroprotective in neurodegenerative diseases. Besides, chronic cerebral hypoperfusion (CCH) causes cognitive impairment in neurodegenerative diseases. Here we tested the protective role of HMGB1 inhibition using anti-HMGB1 neutralizing antibody (Ab) against CCH in rats after bilateral common carotid artery occlusion (2VO). 169 male Sprague-Dawley rats underwent 2VO or sham operation...

Genes responsible for the production of azoreductase enzymes in 2 g negative bacteria, the soil bacterium Pseudomonas putida (AzoP) and the plant pathogen Xanthomonas oryzae (AzoX), were identified. The deduced amino acid sequences of AzoP and AzoX, share 46% amino acid identity to each other. Two different bacterial transcription factors, a repressor (AzoPR) and an activator (AzoXR), in P. putida and X. oryzae, respectively, were found to be divergently oriented to their respective azoreductase genes. Both regulators are LysR-type transcriptional regulators (LTTR) that respond to the azo dye inducer, methyl red (MR)...

Exosomes are membrane nanovesicles implicated in cell-to-cell signaling in which they transfer their molecular cargo from the parent to the recipient cells. This role essentially depends on the exosomes' small size, which is the prerequisite for their rapid migration through the crowded extracellular matrix and into and out of circulation. Here we report much lower exosome mobility than expected from the size of their vesicles, implicate membrane proteins in a substantially impeded rate of migration, and suggest an approach to quantifying the impact...

S-equol is one of gut bacterial metabolites produced from soybean isoflavone daizein. While S-equol is known to promote glucose-induced insulin secretion from pancreatic β cells, whether S-equol affects glucagon-like peptide-1 (GLP-1) secretion from enteroendoceine L cells remains unclear. Here we assessed the effect of S-equol on GLP-1 secretion from mouse enteroendocrine L cell line GLUTag cells. GLUTag cells expressed GPR30 and estrogen receptors, which are putative S-equol receptors. Application of S-equol induced an increase in intracellular Ca2+ levels via GPR30...

BACKGROUND: Targeted quantification of protein biomarkers with liquid chromatography-tandem mass spectrometry (LC-MS/MS) has great potential, but is still in its infancy. Therefore, we elucidated the influence of charge state distribution and matrix effects on accurate quantification, illustrated by the peptide hormone hepcidin. METHODS: An LC-MS/MS assay for hepcidin, developed based on existing literature, was improved by using 5 mM ammonium formate buffer as mobile phase A and as an elution solution for solid phase extraction (SPE) to optimize the charge state distribution...

Yarrowia lipolytica is an oleaginous yeast that is recognized for its ability to accumulate high levels of lipids, which can serve as precursors to biobased fuels and chemicals. Polyketides such as triacetic acid lactone (TAL) can also serve as a precursor for diverse commodity chemicals. This study used Y. lipolytica as a host organism for the production of TAL via expression of the 2-pyrone synthase gene from Gerbera hybrida. Induction of lipid biosynthesis by nitrogen-limited growth conditions increased TAL titers...
