Aims: Little evidence exists supporting the efficacy of regular alcohol urine screening (RAUS) in the management of alcohol dependence, despite recent improvements in urine biomarkers. In this study, we aimed at investigating 1 year, differential clinical correlates between a positive and a negative baseline urine ethyl glucuronide (EtG) screening. Methods: Alcohol-dependent outpatients participating in a previous cross-sectional study where EtG and ethanol diagnostic performances were compared in a double blind design were included...

OBJECTIVES: To demonstrate that miR-9 inhibits autophagy by down-regulating Beclin1 and thus enhances the sensitivity of A549 cells to cisplatin. RESULTS: MiR-9 inhibited Beclin1 expression by binding to its 3'UTR. The inhibition decreased the cisplatin-induced autophagy in A549 cells, evidenced by the decreased expression of LC3II and GFP-LC3 puncta and the increased expression of P62. Upregulation of miR-9 level enhanced the sensibility of A549 cells to cisplatin and increased the cisplatin-induced apoptosis...

We present 2 anonymized cases to identify issues and challenges associated with long-haul in-flight medical emergencies. The first case involved a middle-aged man with a history of carditis on a systemic steroid who developed vomiting and rigor. Four physicians, including a pediatric intensivist, responded to the emergency call. In the second case, a pediatric trainee who was the only onboard medical personnel was summoned for help when a middle-aged man developed acute shortness of breath while traveling on a commercial flight...

To build replicating systems with new functions, the engineering of existing biological machineries requires a sensible strategy. Protein synthesis Using Recombinant Elements (PURE) system consists of the desired components for transcription, translation, aminoacylation and energy regeneration. PURE, might be the basis for a radically alterable, lifelike system after optimization. Here, we regenerated 54 E. coli ribosomal (r-) proteins individually from DNA templates in the PURE system. We show that using stable isotope labeling with amino acids, mass spectrometry based quantitative proteomics could detect 26 of the 33 50S and 20 of the 21 30S subunit r-proteins when co-expressed in batch format PURE system...

BACKGROUND AND AIM OF THE WORK: Nowadays Tuberculosis (TB) is one of the major Public Health problems for several professional categories. According to Italian law, University students are compared to workers: the main risk for them is represented by biological risk, in particular by blood-transmitted or by air-transmitted agents. As for TB, many scientific studies demonstrated that prevalence of latent tuberculosis infection (LTBI) in Medicine and Surgery students was lower than those in health workers and in general population...

Pterodon genus fruits are commercially available at the Brazilian medicinal market used in folk medicine due to their anti-inflammatory, analgesic, and anti-rheumatic effects. Previous studies demonstrated that furanditerpenes possessing vouacapan skeleton, isolated from Pterodon genus, possess expressive antinociceptive activities, with promising moiety for the development of new analgesic products. The antinociceptive properties of compounds 6α,7β- 6α-hidroxivouacapan-7β-17β-lactone (HVL) and 6α-oxovouacapan-7β-17β-lactone (OVL), semi-synthetic analogues of furanditerpenes previously reported as analgesic agents were evaluated on animal experimental models (Spindola et al...

The new direct-acting antivirals agents (DAAs) rapidly changed the treatment approach in chronic hepatitis C (CHC); however, the interferon (IFN)-free therapies availability is currently different in some countries, due to higher costs of these drugs. Naïve treated patients, who are not eligible for IFN-free therapies, could be selected for standard dual treatment with pegylated (PEG)-IFN and ribavirin (RBV), through IFN lambda 3 gene polymorphisms and fibrosis stage evaluation. Inclusion criteria were: naïve treated CHC patients with GT1 or GT4, without major contraindication to PEG-IFN or RBV, with fibrosis stage F0-F2 and IFNL3 rs8099917/rs12979860 TT/CC genotypes...

It has become widely accepted in forensics that, owing to a lack of sensible priors, the evidential value of matching DNA profiles in trace donor identification or kinship analysis is most sensibly communicated in the form of a likelihood ratio (LR). This restraint does not abate the fact that the posterior odds (PO) would be the preferred basis for returning a verdict. A completely different situation holds for Forensic DNA Phenotyping (FDP), which is aimed at predicting externally visible characteristics (EVCs) of a trace donor from DNA left behind at the crime scene...

BACKGROUND: Pounding food items in a wooden mortal is a common home chore in many communities in African and Asian countries. However, no empirical data exist on energy expenditure during this activity, and whether the activity can be considered a light, moderate, or vigorous intensity physical activity is unknown. PURPOSE: This study was aimed at gaining insights into energy expenditure during millet pounding through cardiovascular responses to millet pounding activity, and to explore possible differences in response between women who pound millet as their occupation (habitual millet pounders) and those who pound millet only for their own home cooking but not as a job (nonhabitual pounders)...

It is well-established that the structures dominate the properties. Inspired by the highly contorted and crumpled maxilloturbinate inside dog nose, herein an artificial nanostructure, i.e., 3D crumpled graphene-based nanosheets, is reported with the simple fabrication, detailed characterizations, and efficient gas-sensing applications. A facile supramolecular noncovalent assembly is introduced to modify graphene with functional molecules, followed with a lyophilization process to massively transform 2D plane graphene-based nanosheets to 3D crumpled structure...

An autopilot scheme of volumetric-modulated arc therapy (VMAT)/intensity-modulated radiation therapy (IMRT) planning with the guidance of prior knowledge is established with recorded interactions between a planner and a commercial treatment planning system (TPS). Microsoft (MS) Visual Studio Coded UI is applied to record some common planner-TPS interactions as subroutines. The TPS used in this study is a Windows-based Eclipse system. The interactions of our application program with Eclipse TPS are realized through a series of subroutines obtained by prerecording the mouse clicks or keyboard strokes of a planner in operating the TPS...

We discuss the approach of determining the charge-carrier density of a single-carrier device by combining Ohm's law and the Mott-Gurney law. We show that this approach is seldom valid, due to the fact that whenever Ohm's law is applicable the Mott-Gurney law is usually not, and vice versa. We do this using a numerical drift-diffusion solver to calculate the current density-voltage curves and the charge-carrier density, with increasing doping concentration. As this doping concentration is increased to very large values, using Ohm's law becomes a sensible way of measuring the product of mobility and doping density in the sample...

Objective: After passing of the National Competency-based Learning Objectives Catalogue in Medicine (Nationaler Kompetenzbasierter Lernzielkatalog Medizin, [NKLM, retrieved on 22.03.2016]), the German medical faculties must take inventory and develop their curricula. NKLM contents are expected to be present, but not linked well or sensibly enough in locally grown curricula. Learning and examination formats must be reviewed for appropriateness and coverage of the competences. The necessary curricular transparency is best achieved by systematic curriculum mapping, combined with effective change management...

The de facto commoditization of biomolecular crystallography as a result of almost disruptive instrumentation automation and continuing improvement of software allows any sensibly trained structural biologist to conduct crystallographic studies of biomolecules with reasonably valid outcomes: that is, models based on properly interpreted electron density. Robust validation has led to major mistakes in the protein part of structure models becoming rare, but some depositions of protein-peptide complex structure models, which generally carry significant interest to the scientific community, still contain erroneous models of the bound peptide ligand...

Individual items of any agricultural commodity are different from each other in terms of colour, shape or size. Furthermore, as they are living thing, they change their quality attributes over time, thereby making the development of accurate automatic inspection machines a challenging task. Machine vision-based systems and new optical technologies make it feasible to create non-destructive control and monitoring tools for quality assessment to ensure adequate accomplishment of food standards. Such systems are much faster than any manual non-destructive examination of fruit and vegetable quality, thus allowing the whole production to be inspected with objective and repeatable criteria...
