Human microRNA-125a-5p (miR-125a) is expressed in most tissues where it downregulates the expression of membrane receptors or intracellular transductors of mitogenic signals, thus limiting cell proliferation. Expression of this miRNA generally increases with cell differentiation whereas it is downregulated in several types of tumors, such as breast, lung, ovarian, gastric, colon, and cervical cancers, neuroblastoma, medulloblastoma, glioblastoma, and retinoblastoma. In this study, we focused on hepatocellular carcinoma and used real-time quantitative PCR to measure miR-125a expression in 55 tumor biopsies and in matched adjacent non-tumor liver tissues...

Cystic fibrosis transmembrane conductance regulator (CFTR) is classified as an anion channel transporter of Cl- and HCO3-. Through interactions with its PDZ domain, CFTR is capable of regulating other proteins, such as protein phosphatase 2A (PP2A). The aberrant expression and mutation of CFTR have been observed in several tumor, but not in philadelphia chromosome-positive(Ph+) acute leukemia, including Ph+ B cell acute lymphoblastic leukemia(Ph+ B-ALL) and chronic myelogenous leukemia blast crisis phases (CML-BC)...

Introduction Female skiers suffer from knee injuries twice as much as male skiers, and the risk of an injury to the anterior cruciate ligament (ACL) is three times greater among females compared to males. The sex-specific ACL injury risk depends on internal (e. g. age, skiing skills, fitness level) and external (e. g. slope and weather conditions, ski equipment) factors. However, it is not clear whether male and female recreational skiers with an ACL injury differ regarding the sidecut radius and ski boot sole abrasion...

BACKGROUND: Since the introduction of antiretroviral therapy (ART), human immunodeficiency virus (HIV)-infected patients have a drastically improved prognosis but at the same time they are also more affected by non-HIV related complications, such as chronic kidney disease. The objective of our study was to investigate the effect of proteinuria and tenofovir (TDF)-containing ART regimens on the temporal evolution of estimated glomerular filtration rate (eGFR). METHODS: Between April 2008 and October 2012, we enrolled 395 patients with a complete renal evaluation among patients from the ANRS C03 Aquitaine cohort, a prospective hospital-based cohort of HIV-1-infected patients under routine clinical management in southwestern France...

BACKGROUND: Silicone oil (SO) is used as an intravitreal tamponade agent in vitreoretinal surgery for rhegmatogenous retinal detachment (RRD) complicated by proliferative vitreoretinopathy or with large, multiple retinal tears. Usually, SO is left in the eye for at least 3 months. Although its use can lead to well-known complications, intraocular SO is generally well tolerated. Some studies have reported unexpected central vision loss after SO use or removal. OBJECTIVE: To investigate and analyze the reason for visual loss after the use or removal of intraocular SO in patients who underwent vitrectomy surgeries for RRD...

Epalrestat is clinically applied for the management of diabetic peripheral neuropathy, yet its pharmacokinetic properties are not well understood. In this study, a rapid and sensitive LC-MS/MS method was established for assaying epalrestat in bio-samples of mice. The method was validated and it showed a good linearity over the range of 2-5000ng/mL, a precision of less than 12.3%, and recovery and matrix effects of 112.5-123.6% and 87.9-89.5%, respectively. After administration of a single dose of epalrestat administered, the exposure level of AUC0-∞ was positively dose-dependent and the mean Cmax, AUC0-12h, T1/2, and MRT were 36...

REVIEW
Marcella L Woud, Johan Verwoerd, Julie Krans
Cognitive models of Posttraumatic Stress Disorder (PTSD) postulate that cognitive biases in attention, interpretation, and memory represent key factors involved in the onset and maintenance of PTSD. Developments in experimental research demonstrate that it may be possible to manipulate such biases by means of Cognitive Bias Modification (CBM). In the present paper, we summarize studies assessing cognitive biases in posttraumatic stress to serve as a theoretical and methodological background. However, our main aim was to provide an overview of the scientific literature on CBM in (analogue) posttraumatic stress...

An increased understanding is needed of the physiological effects and plausible biological mechanisms that link PM2.5 (particulate matter with an aerodynamic diameter below 2.5μm) exposure to mortality and morbidities such as atherosclerosis and respiratory disease. PM2.5 causes carcinogenic health effects. Biomonitoring in humans has suggested that 8-oxo-7, 8-dihydro-2-deoxyguanosine (8-oxodG) and N7-methylguanine (N7-MeG) are correlated with oxidative and methylated DNA damage. Thus, it is meaningful to explore the mechanisms of mutagenesis and carcinogenesis associated with oxidative and methylated DNA damage by simultaneously measuring these two markers...

Ke Wang, Linan Che, Chunbo Ma, Yi-Ming Wei
As China becomes the world's largest energy consumer and CO2 emitter, there has been a rapidly emerging literature on estimating China's abatement cost for CO2 using a distance function approach. However, the existing studies have mostly focused on the cost estimates at macro levels (provinces or industries) with few examining firm-level abatement costs. No work has attempted to estimate the abatement cost of CO2 emissions in the iron and steel industry. Although some have argued that the directional distance function (DDF) is more appropriate in the presence of bad output under regulation, the choice of directions is largely arbitrary...

Neuroinflammation has been implicated in the neurobiological pathways of schizophrenia. This meta-analysis evaluated the efficacy and tolerability of adjunctive celecoxib as a noncompetitive anti-inflammation drug in treating schizophrenia. Data were searched, extracted, checked and entered into the RevMan (version 5.3) software by two independent investigators. Standardized/weighted mean differences (SMDs/WMDs), risk ratio (RR) and their 95% confidence intervals (CIs) were calculated, as appropriate. Included were 8 randomized controlled trials (RCTs) with a total of 626 patients with schizophrenia including 316 (50...

OBJECTIVE: Although episiotomies are the commonest obstetric procedure performed the technique of performing one varies amongst obstetricians and midwives. The angle of episiotomy to the midline in particular has been shown to influence the risk of developing obstetric anal sphincter injuries (OASIS). In order to identify the differences in technique and to identify targets for training we undertook a practice survey of episiotomies to analyse the differences in technique between grades of obstetricians and midwives...
