Chen, Xuefei published the artcileEffects of floor- and net-rearing systems on intestinal growth and microbial diversity in the ceca of ducks, HPLC of Formula: 63-68-3, the publication is BMC Microbiology (2022), 22(1), 76, database is CAplus and MEDLINE.

Rearing systems can affect livestock production directly, but whether they have effects on intestinal growth states and ceca microorganisms in ducks is largely unclear. The current study used Nonghua ducks to estimate the effects of rearing systems on the intestines by evaluating differences in intestinal growth indexes and cecal microorganisms between ducks in the floor-rearing system (FRS) and net-rearing system (NRS). The values of relative weight (RW), relative length (RL) and RW/RL of the duodenum, jejunum, ileum and ceca in the FRS were significantly higher than those in the NRS during weeks 4, 8 and 13 (p < 0.05). A total of 157 genera were identified from ducks under the two systems, and the dominant microorganisms in both treatments were Firmicutes, Bacteroidetes, Actinobacteria and Proteobacteria at the phylum level. The distribution of microorganisms in the ceca of the two treatments showed significant separation during the three time periods, and the value of the Simpson index in the FRS was significantly higher than that in the NRS at 13 wk (p < 0.05). Five differential microorganisms and 25 differential metabolic pathways were found in the ceca at week 4, seven differential microorganisms and 25 differential metabolic pathways were found in the ceca at week 8, and four differential microorganisms and two differential metabolic pathways were found in the ceca at week 13. The rearing system influences duck intestinal development and microorganisms. The FRS group had higher intestinal RL, RW and RW/RL and obviously separated ceca microorganisms compared to those of the NRS group. The differential metabolic pathways of cecal microorganisms decreased with increasing age, and the abundance of translation pathways was higher in the NRS group at week 13, while cofactor and vitamin metabolism were more abundant in the FRS group.

Coelho, Paula P. published the artcileEndosomal LC3C-pathway selectively targets plasma membrane cargo for autophagic degradation, Product Details of C5H11NO2S, the publication is Nature Communications (2022), 13(1), 3812, database is CAplus and MEDLINE.

Autophagy selectively targets cargo for degradation, yet mechanistic understanding remains incomplete. The ATG8-family plays key roles in autophagic cargo recruitment. Here by mapping the proximal interactome of ATG8-paralogs, LC3B and LC3C, we uncover a LC3C-Endocytic-Associated-Pathway (LEAP) that selectively recruits plasma-membrane (PM) cargo to autophagosomes. We show that LC3C localizes to peripheral endosomes and engages proteins that traffic between PM, endosomes and autophagosomes, including the SNARE-VAMP3 and ATG9, a transmembrane protein essential for autophagy. We establish that endocytic LC3C binds cargo internalized from the PM, including the Met receptor tyrosine kinase and transferrin receptor, and is necessary for their recruitment into ATG9 vesicles targeted to sites of autophagosome initiation. Structure-function anal. identified that LC3C-endocytic localization and engagement with PM-cargo requires the extended carboxy-tail unique to LC3C, the TBK1 kinase, and TBK1-phosphosites on LC3C. These findings identify LEAP as an unexpected LC3C-dependent pathway, providing new understanding of selective coupling of PM signalling with autophagic degradation

Wang, Baifan published the artcilePrediction and molecular field view of drug resistance in HIV-1 protease mutants, Product Details of C5H11NO2S, the publication is Scientific Reports (2022), 12(1), 2913, database is CAplus and MEDLINE.

Conquering the mutational drug resistance is a great challenge in anti-HIV drug development and therapy. Quant. predicting the mutational drug resistance in mol. level and elucidating the three dimensional structure-resistance relationships for anti-HIV drug targets will help to improve the understanding of the drug resistance mechanism and aid the design of resistance evading inhibitors. Here the MB-QSAR (Mutation-dependent Biomacromol. Quant. Structure Activity Relationship) method was employed to predict the mol. drug resistance of HIV-1 protease mutants towards six drugs, and to depict the structure resistance relationships in HIV-1 protease mutants. MB-QSAR models were constructed based on a published data set of Ki values for HIV-1 protease mutants against drugs. Reliable MB-QSAR models were achieved and these models display both well internal and external prediction abilities. Interpreting the MB-QSAR models supplied structural information related to the drug resistance as well as the guidance for the design of resistance evading drugs. This work showed that MB-QSAR method can be employed to predict the resistance of HIV-1 protease caused by polymorphic mutations, which offer a fast and accurate method for the prediction of other drug target within the context of 3D structures.

Jin, Ruitao published the artcileIon currents through Kir potassium channels are gated by anionic lipids, Name: (S)-2-Amino-4-(methylthio)butanoic acid, the publication is Nature Communications (2022), 13(1), 490, database is CAplus and MEDLINE.

Ion currents through potassium channels are gated. Constriction of the ion conduction pathway at the inner helix bundle, the textbook gate of Kir potassium channels, has been shown to be an ineffective permeation control, creating a rift in our understanding of how these channels are gated. Here we present evidence that anionic lipids act as interactive response elements sufficient to gate potassium conduction. We demonstrate the limiting barrier to K⁺ permeation lies within the ion conduction pathway and show that this gate is operated by the fatty acyl tails of lipids that infiltrate the conduction pathway via fenestrations in the walls of the pore. Acyl tails occupying a surface groove extending from the cytosolic interface to the conduction pathway provide a potential means of relaying cellular signals, mediated by anionic lipid head groups bound at the canonical lipid binding site, to the internal gate.

Hu, Hanqiao published the artcileTranscriptomic analysis of Vigna radiata in response to chilling stress and uniconazole application, Safety of (S)-2-Amino-4-(methylthio)butanoic acid, the publication is BMC Genomics (2022), 23(1), 205, database is CAplus and MEDLINE.

Chilling injury of mung bean (Vigna radiata (L.)) during the blooming and podding stages is a major agricultural threat in Northeast China. Uniconazole (UNZ) can alleviate water deficit stress in soybean and waterlogging stress in mung bean. However, there has been no report on the effect of UNZ application on the growth and transcriptomic profile of mung bean under chilling stress. UNZ application before chilling stress at the R1 stage alleviated the decline in mung bean yield. UNZ delayed the decrease in leaf chlorophyll content under chilling stress at the R1 stage and accelerated the increase in leaf chlorophyll content during the recovery period. Eighteen sep. RNA-Seq libraries were generated from RNA samples collected from leaves exposed to six different treatment schemes. The numbers of DEGs specific for UNZ treatment between D1 + S vs. D1 and D4 + S vs. D4 were 708 and 810, resp. GO annotations showed that photosynthesis genes were obviously enriched among the genes affected by chilling stress and UNZ application. KEGG pathway enrichment anal. indicated that 4 pathways (cutin, suberin and wax biosynthesis; photosynthesis; porphyrin and chlorophyll metabolism; and ribosome) were downregulated, while plant-pathogen interaction was upregulated, by chilling stress. UNZ application effectively prevented the further downregulation of the gene expression of members of these 4 KEGG pathways under chilling stress. UNZ application effectively delayed the decrease in photosynthetic pigment content under chilling stress and accelerated the increase in photosynthetic pigment content during the recovery period, thus effectively limiting the decline in mung bean yield. UNZ application effectively prevented the further downregulation of the gene expression of members of 4 KEGG pathways under chilling stress and increased mung bean tolerance to chilling stress.

Leeper, Alexandra published the artcileTorula yeast in the diet of Atlantic salmon Salmo salar and the impact on growth performance and gut microbiome, COA of Formula: C5H11NO2S, the publication is Scientific Reports (2022), 12(1), 567, database is CAplus and MEDLINE.

Atlantic salmon aquaculture is expanding, and with it, the need to find suitable replacements for conventional protein sources used in formulated feeds. Torula yeast (Cyberlindnera jadinii), has been identified as a promising alternative protein for feed and can be sustainably cultivated on lignocellulosic biomasses. The present study investigated the impact of torula yeast on the growth performance and gut microbiome of freshwater Atlantic salmon. A marine protein base diet and a mixed marine and plant protein base diet were tested, where conventional proteins were replaced with increasing inclusion levels of torula yeast, (0%, 10%, 20%). This study demonstrated that 20% torula yeast can replace fish meal without alteration to growth performance while leading to potential benefits for the gut microbiome by increasing the presence of bacteria pos. associated with the host. However, when torula yeast replaced plant meal in a mixed protein diet, results suggested that 10% inclusion of yeast produced the best growth performance results but at the 20% inclusion level of yeast, potentially neg. changes were observed in the gut microbial community, such as a decrease in lactic acid bacteria. This study supports the continued investigation of torula yeast for Atlantic salmon as a partial replacement for conventional proteins.

Lokeshkumar, Venugopal published the artcileNutritive evaluations of laboratory-reared edible field cricket Coiblemmus compactus Chopard, 1928 (Orthoptera: Gryllidae), for utilising them as an alternate protein source, Recommanded Product: (S)-2-Amino-4-(methylthio)butanoic acid, the publication is Journal of Basic & Applied Zoology (2022), 83(1), 26, database is CAplus.

The increasing world population has made researchers to explore and validate alternate food sources for the future; in that regard, due to the attractive nutritive profile, edible insects ensure the food and feed security in some developing countries. Crickets are orthopteran edible insects widely eaten around the world not as an emergency food but as a delicacy. This present study aims to stabilize a mass rearing technique of field cricket Coiblemmus compactus using cost-effective rearing medium and feed materials. The reared adult crickets were processed and analyzed for its proximate, mineral, amino acid, fatty acid and energy contents. The cost-effective rearing methods were standardised for the cricket species, and the obtained nutritive values were comparatively higher than other edible meat sources. The cricket Coiblemmus compactus had 50.2 ¡À 0.37, 26.50 ¡À 0.80, 8.20 ¡À 1.61, 5.50 ¡À 0.48, 10.93 ¡À 0.19 and 5.40 ¡À 0.16 g/100 g of crude protein, crude fat, carbohydrate, crude fiber, moisture and ash contents, resp. The cricket also possessed higher amounts of potassium (897.83 ¡À 1.55 mg/100 g) and phosphorous elements (604.66 ¡À 4.11 mg/100 g) with 458.30 ¡À 0.29 kcal/100 g of energy content. The chromatog. studies showed the abundance of amino acid and fatty acid contents in the reared edible cricket. The attractive and high-protein nutritive profile of edible cricket Coiblemmus compcatus makes itself an alternate food and feed material to elevate food crisis in developing countries.

Wargny, Matthieu published the artcileNutritional biomarkers and heart failure requiring hospitalization in patients with type 2 diabetes: the SURDIAGENE cohort, Related Products of catalysis-chemistry, the publication is Cardiovascular Diabetology (2022), 21(1), 101, database is CAplus and MEDLINE.

Heart failure (HF) is a growing complication and one of the leading causes of mortality in people living with type 2 diabetes (T2D). Among the possible causes, the excess of red meat and the insufficiency of vegetables consumption are suspected. Such an alimentation is associated with nutritional biomarkers, including trimethylamine N-oxide (TMAO) and its precursors. Here, we aimed to study these biomarkers as potential prognostic factors for HF in patients with T2D. We used the SURDIAGENE (SURvival DIAbetes and GENEtics) study, a large, prospective, monocentric cohort study including 1468 patients with T2D between 2001 and 2012. TMAO and its precursors (trimethylamine [TMA], betaine, choline, and carnitine) as well as thio-amino-acids (cysteine, homocysteine and methionine) were measured by liquid chromatog.-tandem mass spectrometry. The main outcome was HF requiring Hospitalization (HFrH) defined as the first occurrence of acute HF leading to hospitalization and/or death, established by an adjudication committee, based on hospital records until 31st Dec. 2015. The secondary outcomes were the composite event HFrH and/or cardiovascular death and all-cause death. The association between the biomarkers and the outcomes was studied using cause-specific hazard-models, adjusted for age, sex, history of coronary artery disease, NT-proBNP, CKD-EPI-derived eGFR and the urine albumin/creatinine ratio. Hazard-ratios (HR) are expressed for one standard deviation. The data of interest were available for 1349/1468 of SURDIAGENE participants (91.9%), including 569 (42.2%) women, with a mean age of 64.3 ¡À 10.7 years and a median follow-up of 7.3 years [25th-75th percentile, 4.7-10.8]. HFrH was reported in 209 patients (15.5%), HFrH and/or cardiovascular death in 341 (25.3%) and all-cause death in 447 (33.1%). In unadjusted hazard-models, carnitine (HR = 1.20, 95% CI [1.05; 1.37]), betaine (HR = 1.34, [1.20; 1.50]), choline (HR = 1.35, [1.20; 1.52]), TMAO (HR = 1.32, [1.16; 1.50]), cysteine (HR = 1.38, [1.21; 1.58]) and homocysteine (HR = 1.28, [1.17; 1.39]) were associated with HFrH, but not TMA and methionine. In the fully adjusted models, none of these associations was significant, neither for HFrH nor for HFrH and/or CV death, when homocysteine only was pos. associated with all-cause death (HR = 1.16, [1.06; 1.27]). TMAO and its precursors do not appear to be substantial prognosis factors for HFrH, beyond usual cardiac- and kidney-related risk factors, whereas homocysteine is an independent risk factor for all-cause death in patients with T2D.

Prospective biomarker studies can be used to identify biomarkers predictive of disease onset. However, if serum biomarkers are measured years after their collection, the storage conditions might affect analyte concentrations Few data exists concerning which metabolites and proteins are affected by storage at – 20¡ãC vs – 80¡ãC. Our objectives were to document analytes affected by storage of serum samples at – 20¡ãC vs – 80¡ãC, and to identify those indicative of the storage temperature We utilized liquid chromatog. tandem mass spectrometry and Luminex to quantify 300 analytes from serum samples of 16 Finnish individuals with type 1 diabetes, with split-aliquot samples stored at – 80¡ãC and – 20¡ãC for a median of 4.2 years. Results were validated in 315 Finnish and 916 Scottish individuals with type 1 diabetes, stored at – 20¡ãC and at – 80¡ãC, resp. After quality control, we analyzed 193 metabolites and proteins of which 120 were apparently unaffected and 15 clearly susceptible to storage at – 20¡ãC vs – 80¡ãC. Further, we identified serum glutamate/glutamine ratio greater than 0.20 as a biomarker of storage at – 20¡ãC vs – 80¡ãC. The results provide a catalog of analytes unaffected and affected by storage at – 20¡ãC vs – 80¡ãC and biomarkers indicative of sub-optimal storage.

Kwak, Min-Jin published the artcileSophorolipid protects against early-weaning syndrome by improving the gut microenvironment in early-weaned piglets, Application of (S)-2-Amino-4-(methylthio)butanoic acid, the publication is BMC Veterinary Research (2022), 18(1), 8, database is CAplus and MEDLINE.

In animals, weaning stress is the first and most critical stress. Weaning can neg. affect the growth performance of animals phys., psychol., and pathol. Our previous studies on the HT-29 cell line and early-weaned rats demonstrated that adequate sophorolipid (SPL) supplementation in feed could enhance the mucin-producing and wound healing capacities of the gut defense system by modulating gut microbiota. We conducted an experiment with one hundred forty 21-day-old early weaned piglets (L x Y x D). They were allocated into 4 treatment and 7 replications (4 pigs per pen) according to their initial body weight Body weight and feed intake were measured biweekly during exptl. period. After 6 wk, 28 pigs were randomly selected and sacrificed to collect plasma, jejunum, and cecal content samples. Dietary SPL supplementation at 5 and 10 mg/kg quadratically increased the average daily gain during the exptl. period in the treatment groups when compared with the control group. The albumin levels of piglets fed with the SPL supplemented diet were downregulated to the normal range. Moreover, in feed, SPL supplementation at 5 and 10 mg/kg improved jejunal histol. indexes and gene expression levels related to mucin secretion and local inflammation markers. Consistent with these results, adequate SPL supplementation (5 and 10 mg/kg) increased the population of Prevotella, a beneficial bacterium, and its short-chain fatty acid production in the ceca of piglets. The occurrence of diarrhea after weaning in piglets could be reduced by feeding a 10 ppm of SPL supplemented diet which improves the gut defense system by improving the microbial population and enhancing mucin layer integrity.
