The present study aimed to investigate the virulence diversity of Helicobacter pylori (H. pylori) in major ethnic groups residing in Guizhou province, China, and its association with clinical outcomes. Gastric mucosal biopsies were collected from the pylorus of patients with gastrointestinal disorders. H. pylori was identified by colonial morphology, Gram staining, a urease test and H. pylori‑specific 16S rRNA gene fragment PCR amplification. DNA was extracted from pure culture and used for virulence gene analysis...

BACKGROUND: Acne vulgaris (AV) pathogenesis is multifactorial. Vitamin D (VitD) plays an important role in sebocytes' differentiation and function. Most VitD functions are mediated by the nuclear VitD receptor (VDR) following binding of its biologically active form (1,25 dihydroxyvitamin D3). Genetic variations in VDR gene may cause significant receptor dysfunction and have been found to be associated with many inflammatory skin diseases. Two adjacent single nucleotide polymorphisms of VDR, ApaI (rs7975232) and TaqI (rs731236), were commonly studied...

Gaining knowledge about the spread of resistance against antibacterial agents is a primary challenge in livestock farming. The purpose of this study was to test the effect of double antibiotic treatment (at days 10⁻14 and days 26⁻30) with enrofloxacin or solely environmental exposition (identical times, directly into the litter) on resistance against antibacterial agents in commensal Escherichia coli in comparison with the control (without treatment), depending on different flooring. A total of 720 Big 6 turkeys participated in three trials...

Compounds with activity at serotonin (5-hydroxytryptamine) 5-HT2 and α1 adrenergic receptors have potential for the treatment of central nervous system (CNS) disorders, drug addiction or overdose. Isolaureline, dicentrine and glaucine enantiomers were synthesised and their in vitro functional activities at human 5-HT2 and adrenergic α1 receptor subtypes were evaluated. The enantiomers of isolaureline and dicentrine acted as antagonists at 5-HT2 and α1 receptors with (R)-isolaureline showing the greatest potency (pKb = 8...

OBJECTIVE Preemptive administration of analgesic medication is more effective than medication given after the onset of the painful stimulus. The efficacy of preoperative or preemptive pain relief after thoracolumbosacral spine surgery has not been well studied. The present study was a double-blind, placebo-controlled randomized trial of preemptive analgesia with a single-shot epidural injection in adult patients undergoing spine surgery. METHODS Ninety-nine adult patients undergoing thoracolumbosacral operations via a posterior approach were randomized to receive a single shot of either epidural placebo (group 1), hydromorphone alone (group 2), or bupivacaine with hydromorphone (group 3) before surgery at the preoperative holding area...

Plant oil (vegetable) has been evaluated to substitute the mineral-based lubricants due to its natural and friendly characteristics for environment. Availability of vegetable oil made it a renewable source of bio- oils. Additionally, vegetable oil based lubricants has indicated a potentials for reducing hydrocarbon emission and carbon dioxide while utilizing in the IC engines and industrial operations. In this study, the sunflower oil was investigated to study its lubricant characteristics under different loads using the four-ball tribometer and tested the exhaust emissions using a four stroke single cylinder diesel engine...

Background: Orthodontic tooth movement (OTM) is based on induction of periodontal tissue remodeling. Mechanical tooth stimulation results in the release of pro-inflammatory mediators. These mediators cause bone resorption and deposition at the pressure and tension sites and play a role in OTM. Thus, assessment of chemical biomarkers can help determine the exact amount of load and its duration of application required for each tooth and select the most efficient treatment plan with minimal complications...

Physical activity has many beneficial effects on metabolic disorders, such as obesity, insulin resistance, and diabetes. Meteorin-like protein (METRNL), a novel secreted protein homologous to the neurotrophin Metrn, is induced after exercise in the skeletal muscle. Herein, we investigated the effects of METRNL on lipid-mediated inflammation and insulin resistance in skeletal muscle via AMP-activated protein kinase (AMPK) or peroxisome proliferator-activated receptor δ (PPARδ). Treatment with METRNL suppressed inflammatory markers, such as nuclear factor κB (NFκB) nuclear translocation, inhibitory κBα (IκBα) phosphorylation, interleukin-6 (IL-6) expression, and pro-inflammatory cytokines (such as TNFα and MCP-1)...

The main goal of surgery of cholesteatoma is eradication of the disease and revision surgery is indicated when a dry and safe ear has not been achieved. Residual cholesteatoma usually occurs at the sites that are difficult to reach with an operating microscope, such as posterior tympanum and anterior epitympanic recess. Computed tomography can be performed to delineate the extent of disease. High-resolution computed tomography scanning is important for planning for surgery and is indicated for all revision mastoid operations...

Background: Haemophilia A (HA) and Haemophilia B (HB) are X-linked blood disorders that are caused by various mutations in the factor VIII (F8) and factor IX (F9) genes respectively. Identification of mutations is essential as some of the mutations are associated with the development of inhibitors. This study is the first comprehensive study of the F8 mutational profile in Malaysia. Materials and methods: We analysed 100 unrelated HA and 15 unrelated HB patients for genetic alterations in the F8 and F9 genes by using the long-range PCR, DNA sequencing, and the multiplex-ligation-dependent probe amplification assays...

  The present research deals with the development a fast and low-cost method for removing color dye from water using nanosized semiconductors SiO2 as photocatalyst. The studies of kinetic photocatalytic degradation were carried out on an aqueous solution of soluble methylene blue dye, which contained SiO2 nanoparticles and under an ultraviolet light source. Different parameters affecting the process have been studied: catalyst concentration, dye concentration, temperature, and pH of solution. The color variation was detected at three absorption bands (662, 293, and 243 nm)...

PURPOSE: To evaluate the functional outcome of using chitosan-based material in our patients after 2 years of follow-up. METHODS: Nonarthritic nondysplastic femoroacetabular impingement patients with an acetabular chondral lesion, 18 to 55 years of age, were included for arthroscopic repair between May 2013 and July 2015. Full-thickness chondral defects ≥2 cm2 were filled with chitosan-based implant after microfractures. Follow-up consisted of alpha angle assessment and clinical outcome in the form of the Non Arthritic Hip Score (NAHS), International Hip Outcome Tool 33 (iHOT33), Hip Outcome Score of Activities of Daily Living (HOS-ADL), and Hip Outcome Score of Sports Specific Scale (HOS-SSS)...

Women may be aborted due to recent or latent infection during pregnancy or order to flare up of the dormant bradyzoites to acute tachyzoites (latent opportunistic relapse). AIMS: 1) to validate the interpretation of IgM and IgG immunoglobulins seromonotoring with DNA comparative results in differentiating recent from latent T. gondii abortion. METHOD: Blood with the corresponding placental or uterine wash samples were collected from 73 aborted Egyptian women from Cairo and Giza labour wards...
