Duck egg quality improvement is an essential target for Asian poultry breeding. In total, 15 RNA-Seq libraries (magnum, isthmus, and uterus at two different physiological states) were sequenced from 48 weeks old Pekin ducks. De novo assembly and annotation methods were utilized to generate new reference transcripts. Our results revealed that 1264 and 2517 genes were differentially expressed in magnum and uterus in the presence versus absence of an egg, respectively. We identified 1089 genes that were differentially expressed in isthmus compared to uterus (in both presence and absence of a calcifying egg). We observed that 11 common DEGs were detected in the egg white proteomes of 6 different bird species including domestic Chicken, Duck, Goose, Turkey, Quail, and Pigeon. On the other hand, only one of the top five most highly expressed genes in duck isthmus was in this category for the chicken isthmus (SPINK7). Among the large number of DEGs during eggshell formation in ducks, only 41 genes showed a similar differential expression pattern in both duck and chicken. By combining chicken QTL database, chicken oviduct transcriptome and egg proteome data for five bird species, we have obtained high-quality gene lists for egg formation. This is the first study to elucidate the transcriptomic changes in different duck oviduct segments during egg formation, and to integrate QTL, proteome and transcriptome data to probe the functional genes associated with albumen secretion and eggshell mineralization. Sphingomonas sp. Cra20 is a rhizobacteria isolated from the root surface of Leontopodium leontopodioides in the Tianshan Mountains of China and was found to influence root system architecture. We analyzed its ability for plant-growth promotion and the molecular mechanism involved by combining the physiological and genome information. The results indicated that the bacterium enhanced the drought resistance of Arabidopsis thaliana and promoted growth mainly through the strain-released volatile organic compounds. The genome consisted of one circular chromosome and one circular plasmid, containing a series of genes related to the plant-growth promotion. Furthermore, multiple copies of cold-associated genes, general stress response genes, oxidative stress genes and DNA repair mechanisms supported its survivability in extreme environments. In addition, the strain had the ability to degrade xylene and 2, 4-D via a variety of monooxygenases and dioxygenases. This provides further information and will promote the application of Cra20 as a biofertilizer in agriculture. This paper presents methods of reduction of polycyclic aromatic hydrocarbons (PAHs) in grilled or smoked meat and fishery products. Using keywords such as "smoking", "grilling", "processing", "roasting", "barbecue", "curing", "reduction", "decrease", "polycyclic aromatic hydrocarbon", "benzo(a)pyrene", "removal", 1191 references were collected from databases. After sorting, only 37 appeared to be relevant to the topic of the review. read more These 37 papers were coded with one or two keywords representing methods of PAHs reduction using R-based Qualitative Data Analysis library. The results showed that PAHs reduction strategies can be applied either before (or during) grilling or smoking (barrier methods) or after grilling or smoking (removal methods). Before grilling or smoking, use of marinade, preheating of products, appropriate fuel (poor in lignin), filter, collection system of juice and fat (to avoid them dripping into embers) are the main strategies which can be applied. After grilling or smoking, the methods consist of washing the surface of smoked or grilled products with hot water (60 °C) or storing smoked products packed into low density or high density polyethylene. A flowchart regrouping methods which can be used individually or in combination for PAHs reduction in smoked meat and fishery products is suggested. NRAS-mutations arise in 15-20% of all melanomas and are associated with aggressive disease and poor prognosis. Besides, the treatment for NRAS-mutant melanoma are not very efficient and is currently limited to immune checkpoints inhibitors or aggressive chemotherapy. 4-nerolidylcathecol (4-NC), a natural product extracted from Pothomorphe umbellata, induces apoptosis in melanoma cells by ROS production, DNA damage and increased p53 expression, in addition to inhibiting invasion in reconstructed skin. Moreover, 4-NC showed cytotoxicity in BRAF/MEKi-resistant and naive melanoma cells by Endoplasmic Reticulum (ER) stress induction in vitro. We evaluated the in vivo efficacy and the systemic toxicity of 4-NC in a NRAS-mutant melanoma model. 4-NC was able to significantly suppress tumor growth 4-fold compared to controls. Cleaved PARP and p53 expression were increased indicating cell death. As a proof of concept, MMP-2 and MMP-14 gene expression were decreased, demonstrating a possible role of 4-NC in melanoma invasion inhibition. Toxicological analysis indicated minor changes in the liver and bone marrow, but this toxicity was very mild when compared to other proteasome inhibitors and ER stress inductors already described. Our data indicate that 4-NC can counteract melanoma growth in vivo with minor adverse effects, suggesting further investigation as a potential NRAS-mutant melanoma treatment. Toxic stimuli (stressors) exposure limits are typically based on single toxic stimuli experiments but are presently used for both toxic stimuli in isolation and in combination with other toxic stimuli (simultaneous co-exposure or exposures separated in time). In the combination case, typically less of each constituent of the combination is required to cause damage compared to the amount determined from single stressor experiments. Thus, exposure limits based on single toxic stimulus experiments are inadequate for setting limits for stressor combinations. This article presents a recommended simplified approach to improving regulatory exposure limits for toxic stimuli combinations, and a more expansive and expensive alternative of the recommended simplified approach. The recommended approach will partially compensate for the enhanced adverse effects of toxic stimuli combinations relative to adverse effects of toxic stimuli in isolation. The approach covers myriad categories of toxic stimuli reflective of real-lfects that have been under-reported, or 2) exposure limits like the Occupational Safety and Health Administration - Permissible Exposure Limits (OSHA PELs) that are orders of magnitude above levels shown by published single toxic stimuli studies to have caused adverse effects. Practical considerations for the application of this approach are presented. The Spleen Tyrosine Kinase (SYK) is known for its involvement in B-cell and T-cell signaling, modulating the peripheral immune response. We have previously shown that SYK is overactive in the brains of human Alzheimer's Disease (AD) patients, as well as mouse models of AD and tauopathy including Tg Tau P301S mice. More specifically, SYK activation occurs mainly in neurons in human AD brain specimens and mouse models of AD and colocalizes with tau pathogenic species, suggesting it could play a role in AD pathobiology. To assess the possible contribution of SYK to the inflammatory response induced by tau pathology, we analyzed cytokine production in organotypic brain slices cultures from Tg Tau P301S mice and wild-type littermates. Organotypic brains slices from Tau P301S mice produce more cytokines than brain slices from wild-type littermates while SYK inhibition completely antagonizes cytokine production from Tg Tau P301S brain slices. Interestingly, LPS exacerbates the production of pro-inflammatory cytokines in Tg Tau P301S brain sections compared to wild-type organotypic sections while SYK inhibition alleviates the release of pro-inflammatory cytokines induced by LPS. Given that SYK is mainly activated in neurons in Tg Tau P301S mice and not in glial cells, these data suggest that neuronal SYK contributes to the neuroinflammation triggered by the tau pathology. SYK represents an attractive target for regulating the underlying neuroinflammatory component induced by tau pathology. V.The Glucagon Like Peptide 1 Receptor (GLP1R) plays a critical role in selective death of dopaminergic neurons and development of Parkinson's disease (PD). However, little is known about genetic associations of GLP1R gene polymorphisms with PD susceptibility. Therefore, this study aimed to verify whether GLP1R polymorphisms contribute to PD risk in a Chinese Han population. We recruited 518 individuals comprising 259 sporadic PD patients and 259 healthy controls. All of the participants were genotyped for two possibly functional polymorphisms located in GLP1R (rs3765467 and rs6923761) using the Sequenom MassARRAY platform. The frequency of the rs3765467 GG genotype was significantly higher in the PD group compared with that in the control group (OR = 1.444, 95 % CI 1.015-2.055, p =  0.041). Subgroup analysis revealed that male patients and late-onset patients with the rs3765467 GG genotype suffered an increased risk of PD compared with healthy controls (p =  0.021 and p =  0.012, respectively). However, the genotype and allele frequencies for rs6923761 were not significantly different between PD and healthy subjects. Our results indicate that the GLP1R rs3765467 GG genotype is a potential risk factor for PD, especially for male and late-onset PD patients in the Chinese Han population. OBJECTIVE To investigate alternations in spontaneous brain activities reflected by regional homogeneity (ReHo) in patients with delayed encephalopathy after acute carbon monoxide poisoning (DEACMP) using resting-state functional magnetic resonance imaging (rs-fMRI). METHODS Twenty-one patients with DEACMP and 21 age, sex and education matched healthy controls (HCs) received rs-fMRI scanning and clinical assessment. We used the ReHo method to analyze the interregional synchronized activity of all participants. Two sample t-tests were performed to compare the ReHo maps between the two groups. Pearson correlation analysis was then used to assess the correlations between clinical measures and abnormal ReHo in DEACMP patients. RESULTS Compared with HCs, DEACMP patients showed significantly decreased ReHo in bilateral cerebellum posterior lobe, pons, bilateral basal ganglia, while increased in the posterior cingulate, calcarine, bilateral occipital lobe(GRF correction, voxel P value less then 0.001, cluster P value less then 0.05). Negative correlation was found between Mini-mental State Examination (MMSE) scores and the ReHo values of posterior cingulate gyrus (r = -0.672, p  less then  0.05) in the DEACMP group, while positively related to the time from CO poisoning to MRI scan (r = 0.428, p  less then  0.05). CONCLUSION Patients with DEACMP exhibited altered ReHo in the multiple functional brain regions, which provide evidence for local brain dysfunctions and may help to understand the neuropathologic mechanism for the disease. V.This study aimed to advance towards a clinical diagnostic method for detection of cochlear synaptopathy with the hypothesis that synaptopathy should be manifested in elevated masked thresholds for brief tones. This hypothesis was tested in tinnitus sufferers, as they are thought to have some degree of synaptopathy. Near-normal-hearing tinnitus sufferers and their matched controls were asked to detect pure tones with durations of 5, 10, 100, and 200 ms presented in low- and high-level Threshold Equalizing Noise. In addition, lifetime noise exposure was estimated for all participants. Contrary to the hypothesis, there was no significant difference in masked thresholds for brief tones between tinnitus sufferers and their matched controls. Masked thresholds were also not related to lifetime noise exposure. There are two possible explanations of the results 1) the participants in our study did not have cochlear synaptopathy, or 2) synaptopathy does not lead to elevated masked thresholds for brief tones. This study adds a new approach to the growing list of behavioral methods that attempted to detect potential signs of cochlear synaptopathy in humans.
