Nicotine is the main component of cigarettes that causes addiction, which is considered a complex disease, and genetic factors have been proposed to be involved in the development of addiction. The CYP2A6 gene encodes the main enzyme responsible for nicotine metabolism. Depending on the study population, different genetic variants of CYP2A6 associated with cigarette smoking have been described. Therefore, we evaluated the possible association between SNPs in CYP2A6 with cigarette smoking and nicotine addiction-related variables in Mexican mestizo smokers...

OBJECTIVE: The aim of this study was to investigate hMutS proteins in developing human tooth, ameloblastomas, and ameloblastic carcinoma and to determine whether the expression of these proteins has any prognostic potential. STUDY DESIGN: Ten cases of developing human tooth, 39 ameloblastomas, and 2 ameloblastic carcinomas were used to determine the distribution of the proteins during the process of carcinogenesis. Simultaneously, another sample of 73 ameloblastomas was arranged in tissue microarray, and their clinical, microscopic, and radiographic features; treatment outcome; presence of BRAF-V600E mutation; and follow-up data were assessed to determine the prognostic relevance of the expression of hMutS (hMSH2, hMSH3, hMSH6) and Ki-67...

INTRODUCTION: Today's options for biliary bypass procedures, for difficult choledocholithiasis, range from open surgery to laparo-endoscopic hybrid procedures. The aim of this study was to analyze the outcomes of patients with difficult choledocholithiasis treated with laparoscopic choledochoduodenostomy. METHODS: We performed a prospective observational study from March 2011 to June 2016. We included patients with difficult common bile duct stones (recurrent or unresolved by ERCP) in which a biliary bypass procedure was required...

BACKGROUND: There is a current lack of sufficiently high-quality randomized controlled clinical trials that measure the effectiveness of neural tissue mobilization techniques such as median nerve neural mobilization (MNNM) and their specific effects on cervicobrachial pain (CP). This study aim was to compare the effectiveness of MNNM in subjects with CP versus a waiting list control group (WLCG). METHODS: A single-blinded, parallel, randomized controlled clinical trial was performed (NCT02596815)...

Trace elements such as Zinc and Iron are essential components of metalloproteins and serve as cofactors or structural elements for enzymes involved in several important biological processes in almost all organisms. Because either excess or insufficient levels of Zn and Fe can be harmful for the cells, the homeostatic levels of these trace minerals must be tightly regulated. The Zinc regulated transporter, Iron regulated transporter-like Proteins (ZIP) comprise a diverse family, with several paralogues in diverse organisms and are considered essential for the Zn and Fe uptake and homeostasis...

BACKGROUND AIMS: Gene therapy by autologous hematopoietic stem cell transplantation (HSCT) represents a new approach to treat sickle cell disease (SCD). Optimization of the manufacture, characterization and testing of the transduced hematopoietic stem cell final cell product (FCP), as well as an in depth in vivo toxicology study, are critical for advancing this approach to clinical trials. METHODS: Data are shown to evaluate and establish the feasibility of isolating, transducing with the Lenti/β(AS3)-FB vector and cryopreserving CD34(+) cells from human bone marrow (BM) at clinical scale...

The conversion efficiency of high solids waste digestion as sugarcane press mud (P) may be limited due to hydrolysis step. The option of co-digestion with vinasse, main liquid waste generated from ethanol production, was investigated under batch regime at mesophilic conditions (37.5±1°C) and the best mixture was evaluated under semicontinuous regime in stirred-tank reactors. The maximum values for methane yield in batch tests were for V75/P25 and V50/P50 mixtures (on basis of the chemical oxygen demand (COD) percentage added in the mixture), with an average value of 246NmL CH4g(-1) CODfed, which was 13% higher than that of press mud alone...

We report a rare case of diffuse type of gastric cancer with signet ring cells in 10 years old boy who was admitted with a 12 months history with weight loss, dysphagia to solids first and to liquids later, anorexia, fatigue, dizziness, vomiting and later, with pain in the left upper quadrant. On examination, he appeared pale, malnourished, with café-au- lait spots over the trunk and extremities. Laboratory tests showed; Hb 7.5 g, albumin 2.62 g, Thevenon positive on stools. Abdominal ultrasound examination showed periaortic masses and diffuse space occupying lesions in the liver...

The study determined factors associated with patient-reported receipt of survivorship care plans and/or treatment summaries (SCP/TS). Two hundred forty female young adult cancer survivors ages 18-44 completed a web-based survey that included self-report on receiving SCP/TS. Mean age was 32.8 (standard deviation 5.8) years; 20% were diagnosed with cancer at age <21. Only 47% reported receipt of SCP/TS. Age <21 at diagnosis (odds ratio [OR] 2.0, 95% confidence interval [CI] 1.0-3.9), chemotherapy (OR 2...

Staphylococcus aureus is a major etiologic agent of infections in children from the community and the hospital setting. The severity of these conditions is associated with virulence factors, including the Panton-Valentine leukocidin. Both methicillin resistant and sensitive Staphylococcus aureus produce this leukocidin although with varying frequency. We present two children with severe infection by sensitive Staphylococcus aureus producer of Panton-Valentine leukocidin with musculoskeletal and endovascular complications...

Although the transfusionofblood products is common practice, its effects on the immune system have not been adequately studied. A prospective cohort study was conducted in critically ill children followed up until their death, transfer or discharge to establish an association between red blood cell transfusions (RBCTs) and nosocomial infections. A nosocomial infection was considered to be post-transfusional if it occurred within 14 days after RBCT. A total of 162 children were included in the study, 35 (21...

Population genetic structuring is common among herbivorous insects and frequently is associated with divergent host plants, such as crops and their wild relatives. Previous studies showed population genetic structuring in corn leafhopper Dalbulus maidis in Mexico, such that the species consists of two sympatric, host plant-associated populations: an abundant and widespread "pestiferous" population on maize (Zea mays mays), and a small and localized "wild" population on perennial teosinte (Zea diploperennis), a maize wild relative with a limited distribution...

PURPOSE: The CT angiography (CTA) spot sign is a strong predictor of hematoma expansion in intracerebral hemorrhage (ICH). However, CTA parameters vary widely across centers and may negatively impact spot sign accuracy in predicting ICH expansion. We developed a CT iodine calibration phantom that was scanned at different institutions in a large multicenter ICH clinical trial to determine the effect of image standardization on spot sign detection and performance. METHODS: A custom phantom containing known concentrations of iodine was designed and scanned using the stroke CT protocol at each institution...

We imaged the interfacial structure and dynamics of water in a microscopically confined geometry in three dimensions and on millisecond time scales with a 3D structurally illuminated wide-field second harmonic microscope. Image contrast reports on the orientational order of interfacial water, induced by charge-dipole interactions between water molecules and surface charges. The images were converted into surface potential maps. Spatially resolved surface acid dissociation constant pKa,s values were determined for the silica deprotonation reaction by following pH induced chemical changes on the curved and confined surfaces of a glass micro-capillary immersed in aqueous solutions...

BACKGROUND: Normal prenatal neurodevelopment follows stages that are potentially influenced by both chemical and psychosocial environments. Exposure to elevated manganese during this critically vulnerable period has been found to be neurotoxic. Independently, maternal prenatal depression has been associated with subsequent neurodevelopmental decrements in children. The association between child neurodevelopment and prenatal co-exposure to manganese and maternal depression has not been sufficiently studied...
