Aims: Vessel maturation involves the recruitment of mural cells such as pericytes and smooth muscle cells. Laminar shear stress is a major trigger for vessel maturation, but the molecular mechanisms by which shear stress affects recruitment of pericytes are unclear. MicroRNAs (miRs) are small non-coding RNAs, which post-transcriptionally control gene expression. The aim of the present study was to unveil the mechanism by which shear stress-regulated microRNAs contribute to vessel maturation...

It is well-known that occupational and environmental exposure to several factors, including benzene, heavy metals, chemicals and mineral fibers, is associated with the risk of developing a great number of diseases. Numerous studies have been carried out in order to investigate the mechanisms of toxicity of these substances, with particular regard to the possible toxic effects on the immune system. However, little is known about the influence of heavy metals, such as lead, on the immune system in human populations...

Fruit texture is a complex feature composed of mechanical and acoustic properties relying on the modifications occurring in the cell wall throughout fruit development and ripening. Apple is characterized by a large variation in fruit texture behavior that directly impacts both the consumer's appreciation and post-harvest performance. To decipher the genetic control of fruit texture comprehensively, two complementing quantitative trait locus (QTL) mapping approaches were employed. The first was represented by a pedigree-based analysis (PBA) carried out on six full-sib pedigreed families, while the second was a genome-wide association study (GWAS) performed on a collection of 233 apple accessions...

Fruit quality represents a fundamental factor guiding consumers' preferences. Among apple quality traits, volatile organic compounds and texture features play a major role. Proton Transfer Reaction-Time of Flight-Mass Spectrometry (PTR-ToF-MS), coupled with an artificial chewing device, was used to profile the entire apple volatilome of 162 apple accessions, while the fruit texture was dissected with a TAXT-AED texture analyzer. The array of volatile compounds was classed into seven major groups and used in a genome-wide association analysis carried out with 9142 single nucleotide polymorphisms (SNPs)...

Dispersing graphite in water to obtain true (single-layer) graphene in bulk quantity in a liquid has been an unreachable goal for materials scientists in the past decade. Similarly, a diagnostic tool to identify solubilized graphene in situ has been long awaited. Here we show that homogeneous stable dispersions of single-layer graphene (SLG) in water can be obtained by mixing graphenide (negatively charged graphene) solutions in tetrahydrofuran with degassed water and evaporating the organic solvent. In situ Raman spectroscopy of these aqueous dispersions shows all the expected characteristics of SLG...

Hepatocellular carcinoma (HCC) is the most common type of liver cancer in humans. The focal adhesion tyrosine kinase (FAK) is often over-expressed in human HCC and FAK inhibition may reduce HCC cell invasiveness. However, the anti-oncogenic effect of FAK knockdown in HCC cells remains to be clarified. We found that FAK depletion in HCC cells reduced in vitro and in vivo tumorigenicity, by inducing G2/M arrest and apoptosis, decreasing anchorage-independent growth, and modulating the expression of several cancer-related genes...

Previous studies showed the attenuation of both morphine-dependence and morphine-place preference by zinc. Conditioned place preference and aversion are experimental models frequently used to test the reward-stimulating, respectively the aversive effects induced by different stimuli or substances. Addictive substances usually induce place preference (exhibit reward-stimulating properties), while their antagonists determine place-avoidance (aversion). The present study aimed to assess the effect determined by zinc sulphate oral administration (2 and 4 mg/kg/day, 14 days, prior to habituation) on the place aversion induced by two naloxone doses (1...

BACKGROUND: The monitoring and management of risks regarding children and young people admitted to the emergency department as a result of dangerous behaviors distributed via the Internet should be based on clinical reasoning and knowledge about these social media-related phenomena. Here we examine 2 cases of teenagers who reported severe injuries while performing the "planking" craze, a challenge that consists in lying face-down stiffly like a board on any kind of surface. OBJECTIVE: Our objective is to examine and describe the Internet craze called planking, also known as the "lying-down game," through 2 case reports from our experience, enriching this study with information gained through discussions with secondary school teenagers...

OBJECTIVES: Pediatric metabolic syndrome (MetS) is a well-recognized entity; however, there is no consensus on its exact value in predicting long-term cardiovascular (CV) risk. Hepatic steatosis (HS) is another emerging condition associated with pediatric obesity, and data have been reported suggesting a possible role of HS in CV risk linked to MetS. The aim of the present study was to evaluate the usefulness of HS and MetS cluster in predicting CV risk linked to pediatric obesity. METHODS: We studied 803 overweight and obese children (395 girls and 408 boys, mean age 9...

This paper investigates the effect of income- and wealth-based poverty on the probability of being obese for the elderly in Europe by analysing data drawn from the Survey of Health, Ageing and Retirement (SHARE) and the English Longitudinal Study of Ageing (ELSA). We use early-life economic conditions and regional circumstances as instruments for poverty later in life to account for endogeneity issues. After controlling for a large set of covariates at the individual, household, regional and country level, the results show that poverty significantly increases the probability of being obese and the Body Mass Index (BMI), for men and women...

Working memory is a cognitive ability allowing the temporary storage of information to solve problems or adjust behavior. While working memory is known to mainly depend on the medial prefrontal cortex (mPFC), very few is known about how cortical information are relayed subcortically. By its connectivity, the lateral habenula (lHb) might act as a subcortical relay for cortical information. Indeed, the lHb receives inputs from several mPFC subregions, and recent findings suggest a role for the lHb in online processing of spatial information, a fundamental aspect of working memory...

BACKGROUND: Age is commonly accepted as a negative prognostic factor in cartilage surgery, and cutoff values of 30 to 40 years have been previously suggested as treatment indication. However, the lower outcome scores documented in older patients do not take in consideration the decreasing requirements of an aging joint. PURPOSE: To analyze the real effect of age in terms of recovery with respect to the functional level expected for different age categories of patients treated for cartilage lesions...

Objectives: The AtLaS-M randomized trial showed that in patients with HIV-1 RNA <50 copies/mL on atazanavir/ritonavir + two NRTIs, switching to a dual therapy with atazanavir/ritonavir+lamivudine had superior efficacy as compared with continuing the previous triple therapy. This substudy was designed to evaluate at 48 weeks the impact of the dual therapy versus the three-drug atazanavir/ritonavir-based therapy on the HIV-1 cellular reservoir as reflected by the quantification of blood-associated HIV-1 DNA levels...

Environmental pollutants may act as endocrine disruptors in animals. Organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) enter the food chain and may accumulate in the fatty animal tissues, including adrenals. To our knowledge, no previous study has investigated their presence in the human normal adrenal (NA) cortex and aldosterone-producing adenomas (APA). Surgical fragments of APA from 11 patients and NA from 8 kidney donors were analyzed for 16 PCBs congeners and 10 OCPs. A Matrix Solid-Phase Dispersion (MSPD) method for simultaneous determination of the target compounds in cortex homogenates was developed...

BACKGROUND: Molecular techniques are relevant to modern cytopathology, but their implementation is difficult without molecular expertise and infrastructure. The assessment of KRAS mutational status on cytological preparations may be useful either to refine uncertain diagnoses on pancreatic aspirates or to yield predictive information to plan targeted treatment of metastatic colorectal cancer (mCRC). The novel test Idylla™ enables fully automated KRAS genotyping in approximately 2 h, even in less experienced hands...
