LC pups have lower leptin receptor expression at birth and lower energy expenditure and activity during adulthood. CONCLUSION Choline content of diets that are consumed by rats during pregnancy affects the later-life phenotype of offspring, associated with altered in utero programing of hypothalamic food intake regulation. © 2020 WILEY-VCH Verlag GmbH & Co.

Their structures were determined by HRESIMS data, NMR analysis, and X-ray crystallography. Structurally, 1 is characterized as having a quinoline skeleton fused with a 1,4-dioxane motif at the C(7)-C(8) position, whereas 2 possessed an intriguing 1 H -pyrrolo[2,3- g ] quinoline moiety. The cytotoxic activities of these compounds showed no cytotoxicity towards HepG2, A549, and PC9 cancer cell lines and had IC 50 values greater than 20 μ M. © 2020 WILEY-VCH Verlag GmbH & Co.

However, accurate assessment of microbial keratinase activity is not straightforward, and current available methods lack sensitivity and standardization. Here, we suggest an optimized Azokeratin assay, with substrate generated directly from azo-dyed raw keratin material. We introduced supernatant filtration in the protocol for optimal stopping of keratinase reactions instead of the widely used trichloroacetic acid (TCA), as it generated biases and impacted the sensitivity. We furthermore suggest a method for standardization of keratinase activity signals using proteinase K, a well-known keratinase, as a reference enabling reproducibility between studies. Lastly, we evaluated our developed method with several bacterial isolates through benchmarking against a commercial assay (Keratin Azure). Under different setups, the Azokeratin method was more sensitive than commonly used Keratin Azure-based assays (3-fold). We argue that this method could be applied with any type of keratin substrate, enabling more robust and sensitive results which can be used for further comparison with other studies, thus representing an important progress within the field of microbial keratin degradation. © 2020 The Authors.

However, the applicability of the method to water samples with high salinity and low concentration of nitrates is not high. We thus developed a new method to measure δ15 N-NO3 - values in a saline sample with low nitrate concentration by improving the acetone method (the adapted method) and verified tits usability. METHODS The adapted method involves (1) reducing a large volume of sample by evaporation, (2) removing NaCl by mixing acetone twice, (3) changing the volume ratio of the acetone/NaI/n-hexane solvent from 21/0.35/10 mL to 30/0.25/5 mL, (4) using an increased volume of BaI2 (0.1 M) from 0.75 mL to 1 mL, and (5) using an alternative capsule drying process of lyophilization. RESULTS The adapted method has given nearly exact δ15 N-NO3 - values of standard materials with high precision and accuracy ( less then 0.1‰) at a lower cut off of 2 μmol of NO3 - in a sample capsule. Recovery of NO3 - in this method was significantly dependent (p less then 0.05) on the Cl- concentration of the samples. However, a minimum recovery of 60% NO3 - , required for the reproducibility of the accurate value of δ15 N-NO3 - was possible from the concentrated sample aliquot containing up to 6 g of Cl- . Application of the adapted acetone method to creek water samples, collected from mangrove watersheds, has shown high consistency in the analysis results. CONCLUSION It was demonstrated that the inexpensive and easy handling adapted acetone method was applicable in δ15 N-NO3 - analysis for saline water samples when the sample aliquot contained about 4 μmol of NO3 - with less than 6 g of Cl- .

These products often consist of leaves, flowers, bark, roots, seeds and/or other parts of the plant. Many of the pharmacologically active constituents of these products are known, but the pharmacology of these constituents may not be fully elucidated. Natural plant-based products are also available in various forms other than the raw plant material. A wide array of commercial products such as capsules, powders, extracts, and electronic cigarette (e-cigarettes) electronic liquids (e-liquids) are readily available and can be purchased from various outlets, both store-based retailers and online. Newer e-cigarettes are often advertised as "heat not burn" and are used for "vaping" various forms of extracts including "waxes" and "dabs" and raw plant material. METHODS A single manufacturer was found online selling "24 different herbs" in powders, extracts or e-liquids. These were advertised as "legal in tts reserved.AIMS The aim of our study was to investigate noninvasive predictors for detrusor underactivity (DUA) in male patients with lower urinary tract symptoms (LUTS) and benign prostatic enlargement (BPE). METHODS A consecutive series of patients aged 45 years or older with non-neurogenic LUTS were prospectively enrolled. Patients underwent standard diagnostic assessment including International Prostatic Symptoms Score, uroflowmetry, urodynamic studies (cystometry and pressure-flow studies), transrectal ultrasound of the prostate, and ultrasound measurements of the bladder wall thickness (BWT). Logistic regression analysis was used to investigate predictors of DUA, defined as a bladder contractility index  .05) and a net benefit in the range of probabilities between 10% and 80%. CONCLUSIONS According to our results, BWT and Qmax can noninvasively predict the presence of DUA in patients with LUTS and BPE. Although our study should be confirmed in a larger prospective cohort, we present the first available nomogram for the prediction of DUA in patients with LUTS.
