Question: Butyrate has been shown to potently regulate energy expenditure and lipid metabolism in animals, yet the underlying mechanisms remain to be fully understood. The aim of this study was to investigate the molecular mechanisms of butyrate (in the form of butyrate glycerides, BG)-induced lipid metabolism at the level of gene expression in the jejunum and liver of broilers.', 'Two animal experiments were included in this study. In Experiment 1, two hundred and forty male broiler chickens were equally allocated into two groups: 1) basal diet (BD), 2) BG diets (BD + BG). Growth performance was compared between treatments for the 41-day trial. In Experiment 2, forty male broiler chickens were equally allocated into two groups. The general experimental design, group and management were the same as described in Experiment 1 except for reduced bird numbers and 21-day duration of the trial. Growth performance, abdominal fat deposition, serum lipid profiles as well as serum and tissue concentrations of key enzymes involved in lipid metabolism were compared between treatments. RNA-seq was employed to identify both differentially expressed genes (DEGs) and treatment specifically expressed genes (TSEGs). Functional clustering of DEGs and TSEGs and signaling pathways associated with lipid metabolism were identified using Ingenuity Pathways Analysis (IPA) and DAVID Bioinformatics Resources 6.7 (DAVID-BR). Quantitative PCR (qPCR) assays were subsequently conducted to further examine the expression of genes in the peroxisome proliferator-activated receptors (PPAR) signaling pathway identified by DAVID-BR. Dietary BG intervention significantly reduced abdominal fat ratio (abdominal fat weight/final body weight) in broilers. The decreased fat deposition in BG-fed chickens was in accordance with serum lipid profiles as well as the level of lipid metabolism-related enzymes in the serum, abdominal adipose, jejunum and liver. RNA-seq analysis indicated that dietary BG intervention induced 79 and 205 characterized DEGs in the jejunum and liver, respectively. In addition, 255 and 165 TSEGs were detected in the liver and jejunum of BG-fed group, while 162 and 211 TSEGs genes were observed in the liver and jejunum of BD-fed birds, respectively. Bioinformatic analysis with both IPA and DAVID-BR further revealed a significant enrichment of DEGs and TSEGs in the biological processes for reducing the synthesis, storage, transportation and secretion of lipids in the jejunum, while those in the liver were for enhancing the oxidation of ingested lipids and fatty acids. In particular, transcriptional regulators of THRSP and EGR-1 as well as several DEGs involved in the PPAR-α signaling pathway were significantly induced by dietary BG intervention for lipid catabolism.

Answer: Does transcriptome Analysis reveal Regulation of Gene Expression for Lipid Catabolism in Young Broilers by Butyrate Glycerides?


Question: To determine whether obese patients undergoing laparoscopic surgery within an enhanced recovery program had worse short-term outcomes.', 'A prospective study of consecutive patients undergoing laparoscopic colorectal resection was carried out between 2008 and 2011 in a single institution. Patients were divided in groups based on body mass index (BMI). Short-term outcomes including operative data, length of stay, complications and readmission rates were recorded and compared between the groups. Continuous data were analysed using t-test or one-way Analysis of Variance. χ(2) test was used to compare categorical data.', 'Two hundred and fifty four patients were included over the study period. The majority of individuals (41.7%) recruited were of a healthy weight (BMI < 25), whilst 50 patients were classified as obese (19.6%). Patients were matched in terms of the presence of co-morbidities and previous abdominal surgery. Obese patients were found to have a statistically significant difference in The American Society of Anesthesiologists grade. Length of surgery and intra-operative blood loss were no different according to BMI.

Answer: Do obese patients have similar short-term outcomes to non-obese in laparoscopic colorectal surgery?


Question: Most patients with Fusarium infection present with affection of the tegumentary system, with the presence of necrotic and/or inflammatory lesions associated with pain.', 'To evaluate the effect of the intradermal application of a metabolic extract of Fusarium oxysporum in the skin of Wistar rats.', 'The extract was obtained from fungal cultivation in Czapek-Dox medium. It was sterilized by filtration through a Millipore membrane, and injected (0.5 mg/mL) intradermally into the skin of rats, which were killed 3, 6, 12, and 24 h after inoculation. Skin specimens were placed in paraffin and stained using hematoxylin and eosin, and toluidine blue, for the evaluation of the inflammatory response, and Sirius red for the quantification of collagen. Terminal deoxynucleotidyl transferase-mediated UTP nick end labelling (TUNEL) was used for the identification of apoptosis. Tissue reactions were graded and compared over time and compartment.', 'The inflammatory reaction reached a peak at 12 h for both the dermis and subcutaneous region, being graded as moderate and moderate to severe, respectively. There was an influx of granulocytes, lymphocytes, and macrophages. A significant increase in the number of mast cells, as well as the presence of hyperemic vessels and apoptotic bodies, was observed. There was TUNEL staining in keratinocytes, fibroblasts, endothelial cells, muscles, and in the cells of the inflammatory infiltrate. There was a significant decrease in the area occupied by collagen after 12 h.

Answer:
Does metabolic extract of Fusarium oxysporum induce histopathologic alterations and apoptosis in the skin of Wistar rats?
