A series of L-proline-based DESs was prepared through an atom economic reaction between L-proline (L-Pro) and four different kinds of organic acids. The DESs were characterized by Fourier transform infrared spectroscopy (FT-IR), H nuclear magnetic resonance ((1)HNMR), cyclic voltammogram (CV) and the Hammett method. The synthesized DESs were used for the oxidative desulfurization and the L-Pro/p-toluenesultonic acid (L-Pro/p-TsOH) system shows the highest catalytic activity that the removal of dibenzothiophene (DBT) reached 99% at 60°C in 2h, which may involve the dual activation of the L-Pro/p-TsOH...

Although most nervous system diseases affect women and men differentially, most behavioral studies using mouse models do not include subjects of both sexes. Many researchers worry that data of female mice may be unreliable due to the estrous cycle. Here, we retrospectively evaluated sex effects on coefficient of variation (CV) in 5,311 mice which had performed the same place navigation protocol in the water-maze and in 4,554 mice tested in the same open field arena. Confidence intervals for Cohen's d as measure of effect size were computed and tested for equivalence with 0...

A new redox-active 4,5-bisguanidino-substituted o-benzoquinone ligand L is synthesized, that allows a rational access to heterobinuclear complexes by the sequential coordination of two metals. In the examples discussed in this work, mononuclear Cu and Pd complexes are prepared in a first coordination step, and these complexes are then used as precursors to homobinuclear [Cu(II)-L(0)-Cu(II)] and heterobinuclear [Pd(II)-L(0)-Cu(II)] complexes. In the heterobinuclear complex, the Pd(II) is coordinated by the softer bisguanidine side of L and the Cu(II) by the harder dioxolene side (in line with the HSAB concept)...

V. longisporum is an economically important fungal pathogen of brassicaceous crops that originated from at least three hybridization events between different Verticillium spp., leading to the hybrid lineages A1/D1, A1/D2 and A1/D3. Isolates of lineage A1/D1 generally cause stem striping on oilseed rape (Brassica napus), which has recently been reported for the first time to occur in the UK. Intriguingly, the emerging UK population is distinct from the north-central Europe stem striping population. Little is known about the pathogenicity of the newly emerged UK population, hence pathogenicity tests were executed to compare British isolates to previously characterized reference strains...

Prostate cancer is a common hormone-sensitive malignancy, and androgen deprivation therapy (ADT) is a cornerstone of therapy in advanced disease. The most important and controversial of ADT side effects is cardiovascular (CV) toxicity. Prospective trials have demonstrated that ADT increases CV risk by lowering insulin sensitivity, causing dyslipidemia, and causing weight gain thus mimicking metabolic syndrome. Retrospective data suggests that ADT increases CV risk; however, data on cardiovascular mortality is equivocal...

Lipotest(®) is a standardized fat-rich meal designed for use as a test meal during a fat tolerance test (FTT) for the study of postprandial triacylglycerol (TAG) concentrations. Herein we examined the precision and reproducibility of examination using Lipotest(®) on postprandial TAG levels. A total of 26 healthy consenting subjects were examined twice after 8-10 h fasting with an interval of approximately 1 week apart. Blood samples were collected at baseline and 1, 2, 3, and 4 h after consumption of the test meal for measurement of plasma total TAG levels...

Our purpose was to evaluate the within-subject reproducibility of in utero diffusion tensor imaging (DTI) metrics and the visibility of major white matter structures. Images for 30 fetuses (20-33. postmenstrual weeks, normal neurodevelopment: 6 cases, cerebral pathology: 24 cases) were acquired on 1.5 T or 3.0 T MRI. DTI with 15 diffusion-weighting directions was repeated three times for each case, TR/TE: 2200/63 ms, voxel size: 1 ∗ 1 mm, slice thickness: 3-5 mm, b-factor: 700 s/mm(2). Reproducibility was evaluated from structure detectability, variability of DTI measures using the coefficient of variation (CV), image correlation and structural similarity across repeated scans for six selected structures...

OBJECTIVE: Vascular abnormality includes two forms, arteriosclerosis (ARS) and atherosclerosis (ATS), which coexist in patients with cardiovascular (CV) diseases. However, whether their combination may lead to a worsening status in those patients remains unclear. We therefore aimed to investigate the association of ARS and/or ATS with hypertensive target organ damage (TOD). METHODS: From June 2014 to August 2015, a total of 1,599 community-dwelling elderly subjects (aged >65 years) from northern Shanghai were recruited...

BACKGROUND: A single assessment of psychological distress, which includes depression and anxiety, has been associated with increased mortality in patients with coronary heart disease, but the prognostic importance of persistence of distress symptoms is less certain. AIM: To determine whether intermittent and/or persistent psychological distress is associated with long-term cardiovascular (CV) and total mortality in patients with stable coronary artery disease. METHODS: 950 participants in the Long-Term Intervention with Pravastatin in Ischaemic Disease (LIPID) trial completed at least four General Health Questionnaires (GHQ-30) at baseline and after ½, 1, 2 and 4 years...

BACKGROUND: Respiratory rate (RR) is an independent predictor of adverse outcomes and an integral component of many risk prediction scores for hospitalised adults. Yet, it is unclear if RR is recorded accurately. We sought to assess the potential accuracy of RR by analysing the distribution and variation as a proxy, since RR should be normally distributed if recorded accurately. METHODS: We conducted a descriptive observational study of electronic health record data from consecutive hospitalisations from 2009 to 2010 from six diverse hospitals...

The principal molecular mechanisms underlying the cardiovascular (CV) and renal adverse effects of nonsteroidal anti-inflammatory drugs (NSAIDs), such as myocardial infarction and hypertension, are understood in more detail than most side effects of drugs. Less is known, however, about differences in the CV safety profile between chemically distinct NSAIDs and their relative predisposition to complications. In review article, we discuss how heterogeneity in the pharmacokinetics and pharmacodynamics of distinct NSAIDs may be expected to affect their CV risk profile...

Micro-CT is an imaging technique for small tissues and objects that is gaining increased popularity especially as a pre-clinical application. Nevertheless, there is no well-established micro-CT segmentation method, while typical procedures lack sophistication and frequently require a degree of manual intervention, leading to errors and subjective results. To address these issues, a novel segmentation framework, called Independent Active Contours Segmentation (IACS), is proposed in this paper. The proposed IACS is based on two autonomous modules, namely automatic ROI extraction and IAC Evolution, which segments the ROI image using multiple Active Contours that evolve simultaneously and independently of one another...

Down-regulation of photosynthesis is among the most common responses observed in C3 plants grown under elevated atmospheric CO2 concentration ([CO2]). Down-regulation is often attributed to an insufficient capacity of sink organs to use or store the increased carbohydrate production that results from the stimulation of photosynthesis by elevated [CO2]. Down-regulation can be accentuated by inadequate nitrogen (N) supply, which may limit sink development. While there is strong evidence for down-regulation of photosynthesis at elevated [CO2] in enclosure studies most often involving potted plants, there is little evidence for this when [CO2] is elevated fully under open-air field treatment conditions...

Sterol glycosyltransferases (SGTs) catalyze the glycosylation of the free hydroxyl group at C-3 position of sterols to produce sterol glycosides. Glycosylated sterols and free sterols are primarily located in cell membranes where in combination with other membrane-bound lipids play a key role in modulating their properties and functioning. In contrast to most plant species, those of the genus Solanum contain very high levels of glycosylated sterols, which in the case of tomato may account for more than 85% of the total sterol content...

Determination of blood clotting time is essential in monitoring therapeutic anticoagulants. In this work, Parylene-C passivated on quartz crystal microbalance (P-QCM) was developed for the activated partial thromboplastin time (aPTT) measurement. Compared with typical QCM, P-QCM possessed a hydrophobic surface and sensitive frequency response to viscoelastic variations on electrode surface. Fibrin could be adsorbed effectively, due to the hydrophobicity of the P-QCM surface. Comparing with typical QCM, the peak-to-peak value (PPV) of P-QCM was increased by 1...

Estimation of total number of neurons in the Spiral Ganglion (SG) at various ages and their functional status is important as these neurons are constantly exposed to noise and other environmental factors that may lead to neuronal loss with aging due to excitotoxic damage. Parvalbumin (PV) is a calcium-binding protein (CBP), found in highly metabolically active neurons. It helps in buffering cytosolic calcium, which is essential for neurotransmitter release. The neurons in the adult human SG express PV more strongly than other CBPs like calbindin and calretinin...

Ongoing marine monitoring programs are seldom designed to detect changes in the environment between different years, mainly due to the high number of samples required for a sufficient statistical precision. We here show that pooling over time (time integration) of seasonal measurements provides an efficient method of reducing variability, thereby improving the precision and power in detecting inter-annual differences. Such data from weekly environmental sensor profiles at 21 stations in the northern Bothnian Sea was used in a cost-precision spatio-temporal allocation model...
