Spermatogenesis, a highly coordinated process, is prone to environmental insults which may lead to impaired spermatogenesis or, at worst, infertility. Bisphenol A (BPA) is a well-known global environmental toxicant and a ubiquitous oestrogenic chemical. This study evaluated the role of selenium (0.5 ppm sodium selenite/kg diet) on spermatogenesis after BPA treatment in different groups of male BALB/c mice: control, selenium, BPA and selenium+BPA. Markers of oxidative stress and apoptosis were evaluated in testis after BPA treatment...

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths worldwide, mainly because of its poor prognosis. A valid mechanism-based prognostic biomarker is urgently needed. γ-hydroxy-1,N(2) -propanodeoxyguanosine (γ-OHPdG) is an endogenously formed mutagenic DNA adduct derived from lipid peroxidation (LPO). We examined the relationship of γ-OHPdG with hepatocarcinogenesis in two animal models and its potential role as a prognostic biomarker for recurrence in HCC patients. Bioassays were conducted in the Xeroderma pigmentosum group A knockout mice (Xpa(-/-) ), and the diethylnitrosamine (DEN)-injected mice, both prone to HCC development...

Mass spectrometry-based proteomics is a powerful tool for identifying and quantifying proteins in biological samples. While it is routinely used for the characterization of simple cell line systems, the analysis of the cell specific proteome in multicellular organisms and tissues poses a significant challenge. Isolating a subset of cells from tissues requires mechanical and biochemical separation or sorting, a process which can alter cellular signaling, and thus, the composition of the proteome. Recently, several approaches for cell selective labeling of proteins, that include bioorthogonal amino acids, biotinylating enzymes, and genetic tools, have been developed...

The mammalian MSI family of RNA-binding proteins (RBPs) have important roles as oncoproteins in an array of tumor types, including leukemias, glioblastomas, and pancreatic, breast, lung, and colorectal cancers. The mammalian Msi genes, Msi1 and Msi2, have been most thoroughly investigated in two highly proliferative tissues prone to oncogenic transformation: the hematopoietic lineage and the intestinal epithelium. Despite their vast phenotypic differences, MSI proteins appear to have an analogous role in governing the stem cell compartment in both of these tissues, potentially providing a paradigm for a broader understanding of MSI function and oncogenic activities...

OBJECTIVE: Regarding technical difficulties that obese body habitus might impose to percutaneous nephrolithotomy (PNL) success and higher risk of peri-operative complications in this group of patients, we decided to retrospectively gather data from our patients during past 8 years to determine the stone free and complication rates. MATERIAL AND METHODS: Between January 2007-December 2015, seventy-eight obese patients with body mass index over 35 who had indication for PNL including stones larger than 2 cm in pelvi-calyceal system or smaller extracorporeal shock wave lithotripsy (ESWL) resistant stones or who were not a fit candidate for ESWL due to increased skin to target distance, with no contraindication of PNL (including bleeding diathesis, inability to be positioned in prone) were enrolled...

Mortality related to severe-moderate and severe ARDS remains high. We searched the literature to update this topic. We defined severe hypoxemic respiratory failure as PaO2/FIO2 < 150 mm Hg (i.e., severe-moderate and severe ARDS). For these patients, we support setting the ventilator to a tidal volume of 4-8 mL/kg predicted body weight (PBW) with plateau pressure ≤30 cm H2O, and initial PEEP of 10 - 12 cm H2O. To promote alveolar recruitment, we propose increasing PEEP in increments of 2 - 3 cm, provided plateau pressure remains ≤30 cm H2O and driving pressure does not increase...

BACKGROUND: Acute pyelonephritis is associated with renal scarring in up to 30% of patients. Renal scarring may cause significant long-term morbidity. The pathogenesis of acute pyelonephritis remains unclear, although it involves interaction among uroepithelium, the immune system cells, and the locally produced cytokines. That some UTI-prone children develop acute pyelonephritis, and eventually renal parenchymal scarring, suggests a genetic role. Interleukin-6, interleukin-8, chemokine receptor-1 (CXCR1), and tumor necrosis factor-alpha (TNFα), the key regulators of the host immune responses, are proteins whose secretion is controlled by genes...

Maize (Zea mays L.) is a globally important staple food crop prone to contamination by aflatoxin, a carcinogenic secondary metabolite produced by the fungus Aspergillus flavus. An efficient approach to reduce accumulation of aflatoxin is the development of germplasm resistant to colonization and toxin production by A. flavus. Lipoxygenases (LOXs) are a group of non-heme iron containing dioxygenase enzymes that catalyze oxygenation of polyunsaturated fatty acids (PUFAs). LOX derived oxylipins play critical roles in plant defense against pathogens including A...

Assessment of milk production is of utmost relevance for pediatricians and scientists interested in early life nutrition. The weight-suckle-weight (WSW) method, which consists of weighing babies before and after they suckle their mother, uses the difference in body weight as an estimate of milk intake. However, this is prone to many sources of error. In the current study, we used for the first time the water turnover method and compartmental analysis with deuterated water (D2O) as a non-toxic tracer to quantify in vivo milk production in a rat model...

In Magnetic Resonance Imaging (MRI), the stream function-based method is commonly used in the design of gradient coils. However, this method can be prone to errors associated with the discretization of continuous current density and wire connections. In this work, we propose a novel gradient coil design scheme that works directly in the wire space, avoiding the system errors that may appear in the stream function approaches. Specifically, the gradient coil pattern is described with dedicated spiral functions adjusted to allow the coil to produce the required field gradients in the imaging area, minimal stray field and other engineering terms...

There is a plethora of Calcium phosphate (CaP) scaffolds used as synthetic substitutes to bone grafts. The scaffold performance is often evaluated from the quantity of bone formed within or in direct contact with the scaffold. Micro computed tomography (µCT) allows three-dimensional evaluation of bone formation inside scaffolds. However, the almost identical x-ray attenuation of CaP and bone obtrude the separation of these phases in µCT images. Commonly, segmentation of bone in µCT images is based on gray scale intensity, with manually determined global thresholds...

Chronic kidney disease (CKD) concerns about 10 % of the population in Switzerland. Epidemiological studies suggest that women are less prone to the development of CKD than men, and progress less rapidly to end stage renal disease. This protection seems lost when entering menopause. The reasons for this finding may stem from hormonal, structural or hemodynamic differences, yet the precise underlying mechanisms are so far incompletely understood. Some animal studies suggest a potentially beneficial effect of estrogen therapy, mainly in diabetes, yet data in humans are lacking...

The genetic basis combined with the sporadic occurrence of amyotrophic lateral sclerosis (ALS) suggests a role of de novo mutations in disease pathogenesis. Previous studies provided some evidence for this hypothesis, however results were conflicting: no genes with recurrent occurring de novo mutations were identified and different pathways were postulated. In this study we analyzed whole-exome data from 82 new patient-parents trios and combined it with the datasets of all previously published amyotrophic lateral sclerosis trios (173 trios in total)...

To achieve a better understanding of entrepreneurship development in women, longitudinal data on 672 individuals collected from 1922 to 1959 were analysed in a secondary investigation of the Terman Longitudinal Study. Women's reports on their occupations during 10 different years were assigned to one of two categories: work for pay (0/1), and work allowing for self-employment (0/1) in the respective year. Structural equation modelling supported earlier results concerning male entrepreneurial activity. Personality and aspects of the parenting context the women had experienced by the average age of 12 predicted early entrepreneurial competencies (inventions, leadership) and occupational interests by age 13, which related to an entrepreneurship-related career goal in 1936, when the participants were about 27 years of age on average...

Trichocorixa verticalis (T. verticalis), native to North America and the Caribbean islands, is an invasive waterboatman species (Corixidae) in the southwest of the Iberian Peninsula. Previous studies in the native range have suggested that predation by T. verticalis can regulate the abundance of Anostracan and Cladoceran zooplankton in saline ecosystems, causing increases in phytoplankton through a trophic cascade. In this experimental study, we tested the predator-prey relationship between the native brine shrimp Artemia parthenogenetica, and T...
