BACKGROUND AND PURPOSE: Posttranslational modifications of cysteine (Cys) residues represent a major aspect of redox biology, and their reliable detection is key in providing mechanistic insights. The metastable character of these modifications and cell lysis-induced artifactual oxidation render current state-of-the-art protocols to rely on alkylation-based stabilization of labile Cys derivatives before cell/tissue rupture. An untested assumption in these procedures is that for all Cys derivatives alkylation rates are faster than their dynamic interchange...

Protein energy wasting (PEW) is a condition commonly occurring among patients with ESRD on hemodialysis. PEW is characterized by depletion of protein and energy stores and is caused by multiple factors related to chronic kidney disease, acute and chronic comorbidities and by renal replacement therapy itself. Anorexia is central in the pathogenesis of PEW; it is frequently observed in these patients whose protein and energy intakes are typically lower than guidelines recommendations. If untreated, PEW invariably leads to major complications, and may activate a vicious circle with further worsening of nutritional status...

Incorrect prosthesis size has direct impact on patient outcome after transcatheter aortic valve implantation (TAVI) procedure. Currently, annular diameter, area or perimeter may be used for prosthesis size selection. The aim was to evaluate whether the use different annular dimensions would result in the selection of different prosthesis sizes, when assessed in the same TAVI-candidate during the same phase of a cardiac cycle. Fifty consecutive TAVI-candidates underwent retrospectively ECG-gated computed tomography angiography (CTA)...

Traumatic brain injury (TBI) is the main cause of disability in people younger than 35 in the United States. The mechanisms of TBI are complex resulting in both focal and diffuse brain damage. Fractal dimension (FD) is a measure that can characterize morphometric complexity and variability of brain structure especially white matter (WM) structure and may provide novel insights into the injuries evident following TBI. FD-based brain morphometry may provide information on WM structural changes after TBI that is more sensitive to subtle structural changes post injury compared to conventional MRI measurements...

Numerous functional magnetic resonance imaging studies have been conducted to elucidate emotion processing of patients with bipolar disorder (BD), but due to different inclusion criteria used, especially for the history of medication use, the results for euthymic BD patients are inconsistent. For this reason, brain functional effects of psychopharmacological treatments on BD patients have been investigated by numerous fMRI studies, but there is no existing report for brain functional effects of different mood stabilizers...

The potential energy surface of Zn n O n clusters (n = 2, 4, 6, 8) has been explored by using a simulated annealing method. For n = 2, 4, and 6, the CCSD(T)/TZP method was used as the reference, and from here it is shown that the M06-2X/TZP method gives the lowest deviations over PBE, PBE0, B3LYP, M06, and MP2 methods. Thus, with the M06-2X method we predict isomers of Zn n O n clusters, which coincide with some isomers reported previously. By using the atoms in molecules analysis, possible contacts between Zn and O atoms were found for all structures studied in this article...

PURPOSE: The pivotal trials for stroke prevention in non-valvular atrial fibrillation (NVAF) compared rivaroxaban, dabigatran, and apixaban with warfarin, as did most claims-based studies. Comparisons with phenprocoumon, the most frequently used vitamin K antagonist (VKA) in Germany, are scarce. METHODS: Risk of bleeding, ischemic stroke, and all-cause mortality in patients with NVAF were analyzed using data for 2010 to 2014 from a large German claims database. New users of oral anticoagulants from January 2012 to December 2013 were included and observed over 1 year...

Vitamin D3 deficiency was found to be tightly linked to many health problems including metabolic syndrome, cancer, cardiovascular diseases, and type 2 diabetes mellitus. In our study, we tested the possible antidiabetic effects of one of vitamin D3 analogs, alfacalcidol, solely or in a combination with metformin on type 2 diabetic rats. Type 2 diabetic model rats were induced by feeding high-fat diet for 4 weeks followed by intraperitoneal injection of streptozotocin. In addition to the control group, the diabetic rats were divided into four groups: untreated, metformin-treated, alfacalcidol-treated, and combination-treated group (metformin + alfacalcidol) for 4 weeks...

All dynamic species interaction models contain an assumption that describes how contact rates scale with population density. Choosing an appropriate contact-density function is important, because different functions have different implications for population dynamics and stability. However, this choice can be challenging, because there are many possible functions, and most are phenomenological and thus difficult to relate to underlying ecological processes. Using one such phenomenological function, we described a nonlinear relationship between field transmission rates and host density in a common snail-oligochaete symbiosis...

China is one of three global hotspots for nitrogen (N) deposition, which has concerned scientists and the public. While previous studies on N deposition in China have focused on its composition, spatial pattern, and interannual dynamics, its monthly dynamics in different regions remain unclear, hindering our ability to evaluate its ecological effects. Therefore, we obtained monthly wet N deposition data from196 sites after continuous network observations and published data in China and analyzed the monthly dynamics of NH4 + -N, NO3 - -N, and dissolved inorganic N (DIN=NH4 + -N+NO3 - -N) deposition fluxes on site, regional, and national scales...

Recently, VEGFR-2 has been detected not only in vascular and lymphatic endothelial cells but also in some non-vascular endothelial cells, particularly human hair follicles, sebaceous glands, and sweat glands. In addition, VEGFR-2 has been confirmed to play direct roles in hair follicle keratinocyte regulation beyond simply angiogenesis. To elucidate whether VEGFR-2 activation plays a role in hair follicle cycling regulation, immunofluorescence of VEGFR-2 expression was performed during hair cycling of the dorsum of the mouse induced by hair plucking...

In the soybean cultivar Suweon 97, BCMV-resistance gene was fine-mapped to a 58.1-kb region co-localizing with the Soybean mosaic virus (SMV)-resistance gene, Rsv1-h raising a possibility that the same gene is utilized against both viral pathogens. Certain soybean cultivars exhibit resistance against soybean mosaic virus (SMV) or bean common mosaic virus (BCMV). Although several SMV-resistance loci have been reported, the understanding of the mechanism underlying BCMV resistance in soybean is limited. Here, by crossing a resistant cultivar Suweon 97 with a susceptible cultivar Williams 82 and inoculating 220 F2 individuals with a BCMV strain (HZZB011), we observed a 3:1 (resistant/susceptible) segregation ratio, suggesting that Suweon 97 possesses a single dominant resistance gene against BCMV...

BACKGROUND: Pregnancy after bariatric surgery (BS) has an increased risk for small-for-gestational-age infants (SGA), shorter length of gestation, and probably perinatal mortality. The aim of this study was to investigate if biliopancreatic diversion could impair pregnancy outcomes in comparison to other bariatric surgery procedures. METHODS: We conducted a cohort retrospective single-center study in 65 women before and after BS. Thirty-one pregnancies occurred before BS, while 109 after BS, amongst which n = 51 after biliopancreatic diversion (BPD) and n = 58 after non-malabsorptive procedures...
