The reaction kinetics of dimethyl carbonate (DMC) and OH radicals were investigated behind reflected shock waves over the temperature range of 872-1295 K and at pressures near 1.5 atm. Reaction progress was monitored by detecting OH radicals at 306.69 nm using a UV laser absorption technique. The rate coefficients for the reaction of DMC with OH radicals were extracted using a detailed kinetic model developed by Glaude et al. (Proc. Combust. Inst. 2005, 30(1), 1111-1118). The experimental rate coefficients can be expressed in Arrhenius form as: kexpt'l = 5...

The role of total solids (TS) content on sludge mesophilic anaerobic digestion (AD) was investigated in batch reactors. A range of TS below 10% was evaluated with two replicates. The volumetric biogas production rate (VBPR) increased with increasing initial TS. On day 5, VBPR increased from 133.2±11.2mLL(-1)d(-1) at TS 2% to 1111.7±58.1mLL(-1)d(-1) at TS 10%. The ultimate biogas yield (P) firstly increased and then decreased with the increasing TS. The greatest P was 246.8mLg(-1)-VSadded at TS 8%. The corresponding free ammonia nitrogen (FAN) and total ammonia nitrogen (TAN) were 84...

Background: Chemokine genetic variations are involved in infectious diseases such as hepatitis B virus (HBV). Several allelic variants might, in theory, affect the outcome of vaccination. Objectives: This study was carried out to examine the associations of Δ32 CCR5 and 190G > A CCR2 polymorphisms with a response to a primary course of three HBV vaccinations. Methods: Between December 2014 and December 2016, patients from three randomly selected primary care clinics in the West Pomeranian region (Poland), 1 month after receiving the third dose of HBV vaccine, were enrolled...

Biologics has been widely used in the treatment of rheumatoid arthritis. We aimed to determine whether etanercept, a TNF-α inhibitor (TNFi) that is used to treat patients with rheumatoid arthritis (RA), affects cancer risk.This retrospective matched cohort study used data in the Registry of Catastrophic Illness Database in Taiwan from January 1, 1996 to December 31, 2010. RA, all-cancer, and solid cancer were defined using International Classification of Disease codes (ICD-9-CM 714.X, 140-208, and 140-199, respectively)...

This study investigates the influence of age and sex on the volumes of the pituitary fossa and gland in 91 males and 108 females from Croatia who underwent magnetic resonance imaging of the endocranium for complaints not related to the pituitary gland. Isometric 3DT1 MPRAGE and 3DT1 MPR sequences were obtained on 1.5. Tesla and analysed on ISSA software. The volumes were obtained from the sum of all the areas multiplied by the thickness of the section. The mean volume of the pituitary fossa for males was 1111...

PURPOSE: To propose a 3D quantitative high-resolution T1 mapping technique, called 3D SASHA (saturation-recovery single-shot acquisition), which combines a saturation recovery pulse with 1D-navigator-based-respiratory motion compensation to acquire the whole volume of the heart in free breathing. The sequence was tested and validated both in a T1 phantom and in healthy subjects. MATERIALS AND METHODS: The 3D SASHA method was implemented on a 1.5T scanner. A diaphragmatic navigator was used to allow free-breathing acquisition and the images were acquired with a resolution of 1...

Staphylococcus aureus TF2758 is a clinical isolate from an atheroma and a super-biofilm-elaborating/polysaccharide intercellular adhesin (PIA)/poly-N-acetylglucosamine (PNAG)-overproducing strain (L. Shrestha et al., Microbiol Immunol 60:148-159, 2016, https://doi.org/10.1111/1348-0421.12359). A microarray analysis and DNA genome sequencing were performed to identify the mechanism underlying biofilm overproduction by TF2758. We found high transcriptional expression levels of a 7-gene cluster (satf2580 to satf2586) and the ica operon in TF2758...

Apical leaf curl disease, caused by tomato leaf curl New Delhi virus-[potato] (ToLCNDV-[potato]) is one of the most important viral diseases of potato in India. Genetic resistance source for ToLCNDV in potato is not identified so far. However, the cultivar Kufri Bahar is known to show lowest seed degeneration even under high vector levels. Hence, microarray analysis was performed to identify differentially regulated genes during ToLCNDV-[potato] infection in a resistant (Kufri Bahar) and a susceptible cultivar (Kufri Pukhraj)...

BACKGROUND AND OBJECTIVES: Needle-induced nerve trauma and intraneural injection can lead to neurologic injury during peripheral nerve blocks. In this study, we assessed the utility of opening injection pressure (OIP), time to OIP, and rate of rise to OIP in detecting needle-nerve contact and intraneural injection. METHODS: Five common ultrasound-guided blocks of the femoral, saphenous, subgluteal sciatic, tibial, and common peroneal nerves were simulated in 10 fresh cadavers...

PURPOSE: To investigate the prevalence and incidence of myopic choroidal neovascularization (CNV) in Taiwan, including the health care utilization and treatment-associated costs. METHODS: A retrospective cohort study using existing data from the Taiwanese National Health Insurance claims database to identify patients who had a diagnosis of myopic CNV recorded from 1 January 2009 to 31 December 2011. The prevalence of myopic CNV was monitored during this period, and the frequency and cost of both treatment visits and monitoring visits were analyzed for 2 years following diagnosis...

Gait impairment is one of the most intractable symptoms of Parkinson's disease, responding poorly to dopaminergic medication. Promising therapeutic strategies include deep brain stimulation (DBS) of the pedunculopontine nucleus (PPN) and enhancing cholinergic neurotransmission by acetylcholine esterase inhibitors. This Editorial discusses an elegant study by Janickova and coworkers in the current issue of the Journal of Neurochemistry, in which the authors engineered mice lacking cholinergic transmission selectively in the PPN and demonstrate that cholinergic neurons of the PPN are critical for gait...

The aim of this analysis was to examine sex-based differences in renal segmental resistances in healthy controls (HC) and patients with type 1 diabetes (T1D). We hypothesized that hyperfiltration - an early hemodynamic abnormality associated with diabetic nephropathy (DN) - would disproportionately affect women with T1D, thereby attenuating protection against the development of renal complications. Glomerular hemodynamic parameters were evaluated in HC (n=30) and in normotensive, normoalbuminuric patients with T1D and either baseline normofiltration (n=36, T1D-N, glomerular filtration rate [GFR] 90-134 ml/min/1...

Limited resources and access to healthcare in sub-Saharan Africa are associated with high rates of malnourished children, although many countries globally are demonstrating increasing childhood obesity. This study evaluated how well current age- or height-based formulae estimate the weight of children undergoing surgery in Zambia. All children under 14 years of age presenting for elective surgery at the University Teaching Hospital, Lusaka, had both height and weight measured. Their actual weight was compared against estimated weight from various formulae...
