The oxidative stress is a key issue in the etiology of non-alcoholic fatty liver disease (NAFLD). The aim of our study was to evaluate the effect of metabolic gene polymorphisms involved in the oxidative stress (GSTT1, GSTM1, SULT1A1, CYP2E1, and 1A1), lifestyle and nutrition aspects, and their interaction, on the risk of NAFLD. We enrolled 294 cases and 359 controls, and collected demographics, anthropometric, lifestyle, and nutrition data. A subgroup of NAFLD provided additional data on nutrients and on physical activity engagement. Each patient provided a blood sample for DNA extraction and genotyping. Clinical and laboratory data were collected from cases. Multivariable analysis shows a significant protective effect of age, gender, and moderate drinking habits on the risk of NAFLD, while an increased risk for greater consumption of fruit and grilled meat or fish. Significant interactions were reported between alcohol consumption, fruit intake, grilled meat and fish, and selected genetic variants. From the subgroup analysis, a moderate/high consumption of fat and/or grilled meat/fish, and a high consumption of white meat increase the risk of NAFLD. Engaging any physical activity at least 1 time/ week halves the risk of NAFLD. Besides confirming the beneficial effect of moderate alcohol intake and regular physical activity, and the increased risk associated with high fruit and fat intake, for the first time, we report a detrimental effect of grilled food on NAFLD risk. An effect modification by selected gene variants increases the risk in combination with fruit and grilled food intake.

Mannose-binding lectin (MBL) plays a key role in the human innate immune response. It has been shown that polymorphisms in the MBL2 gene, particularly at codon 54 (variant allele B; wild-type allele designated as A), impact upon host susceptibility to Candida infection. This systematic review and meta-analysis were performed to assess the association between MBL2 codon 54 genotype and vulvovaginal candidiasis (VVC) or recurrent VVC (RVVC). Studies were searched in MEDLINE, SCOPUS, and ISI Web of Science until April 2013. Five studies including 704 women (386 cases and 318 controls) were part of the meta-analysis, and pooled ORs were calculated using the random effects model. For subjects with RVVC, ORs of AB versus AA and of BB versus AA were 4.84 (95% CI 2.10–11.15; P for heterogeneity = 0.013; I 2 = 68.6%) and 12.68 (95% CI 3.74–42.92; P for heterogeneity = 0.932, I 2 = 0.0%), respectively. For subjects with VVC, OR of AB versus AA was 2.57 (95% CI 1.29–5.12; P for heterogeneity = 0.897; I 2 = 0.0%). This analysis indicates that heterozygosity for the MBL2 allele B increases significantly the risk for both diseases, suggesting that MBL may influence the women's innate immunity in response to Candida.

The misuse of psychoactive substances is attracting a great deal of attention from the general public. An increase use of psychoactive substances is observed among young people who do not have enough awareness of the harmful effects of these substances. Easy access to illicit drugs at low cost and lack of effective means of routine screening for new psychoactive substances (NPS) have contributed to the rapid increase in their use. New research and evidence suggest that drug use can cause a variety of adverse psychological and physiological effects on human health (anxiety, panic, paranoia, psychosis, and seizures). We describe different classes of these NPS drugs with emphasis on the methods used to identify them and the identification of their metabolites in biological specimens. This is the first review that thoroughly gives the literature on both natural and synthetic illegal drugs with old known data and very hot new topics and investigations, which enables the researcher to use it as a starting point in the literature exploration and planning of the own research. For the first time, the conformational analysis was done for selected illegal drugs, giving rise to the search of the biologically active conformations both theoretically and using lab experiments.

To our knowledge, this is the first study reporting an association between BER SNP and HCC risk in a population of central-southern Italy.

Cephalometry is a measurement of the head by imaging, also taking into account the layer which consists of all the soft tissues of the head. Following the introduction of computed tomography (CT), 3D reconstruction of the head and neck structures and 3D analysis of angular and linear cephalometric parameters was enabled. This study aimed to determine the characteristic cephalometric parameters, using the 2D reconstruction of the multi-slice CT (MSCT) images, which are essential for computer designing of the parametric-geometric-mathematical model (PGMM) of the human skull. We conducted the study on 20 CT scans of adult patients (12 males and 8 females), taken from the radiology archive of the Clinical Center in Niš. Measurements were done on 2D reconstruction images of preselected 3D images of the human head created using MSCT. The values of 29 linear cephalometric parameters (LCP) and 20 angular cephalometric parameters (ACP) were determined. Statistically significant differences between males and females were noted for the distance between the points Sella and Supraorbitale and for the distance between the points Subspinale and Labium superius. Mean values of cephalometric parameters obtained by measurements on 2D CT images can be used to generate normative parameters which represent values used to generate 3D PGMM of the human skull. This PGMM of the skull may allow a more accurate diagnosis, better selection of treatment methods and more accurate prognosis for healing in orthodontics, implantology, oral and maxillofacial surgery.
