Fluid Challenge and Plasma Volume, During Surgery

ABSTRACT: A short bolus infusion of fluid, called "fluid challenge" is commonly recommended for fluid treatment during longer surgery. However a prolonged increase of the blood volume is a prerequisite to recommend the technique. The purpose with the study is to examine the plasma expanding effect of three different fluid challenge strategies (acetated Ringers 4 ml/kg body weight, albumin 5% 4 ml/kg body weight or albumin 20% 1 ml/kg body weight), using hemoglobin as a dilution indicator.

Coordinated Changes in Xenobiotic Metabolizing Enzyme Gene Expression in Aging Male Rats: Brown Norway and F344

Project description:In order to gain insight into the effects of aging on susceptibility to environmental toxins, we characterized the expression of xenobiotic metabolizing enzymes (XMEs) from the livers of male Brown Norway and F344 rats across the adult lifespan. To examine metabolic processes across lifespan after challenge with a xenobiotic compound, Brown Norway rats were exposed to 1.0 g/kg body weight toluene by oral gavage in corn oil (4ml/kg body weight) or corn oil alone. Keywords: age effect on toxin susceptibility

Effect of beta3 adrenergic activation on liver gene expression profile in mice (C57Bl/6J) expressing hepatocyte PPARalpha or not

Project description:Pparα hepatocyte-specific knockout (Pparαhep-/-) mice were generated at INRAE’s rodent facility (Toulouse, France) by mating the floxed-Pparα mouse strain with C57BL/6J albumin-Cre transgenic mice to obtain albumin-Cre+/-Pparαflox/flox mice (LKO). Albumin-Cre-/-Pparαflox/flox (Pparαhep+/+) littermates were used as controls (LWT). Twelve week-old mice were transferred in a ventilated cabinet at the specific temperature of 30°C (thermoneutrality) 2 weeks before experiments. Mice were fed ad libitum or fasted at ZT0 and given beta3 adrenergic receptor agonist: CL316243 ((3 mg/kg body weight; Sigma Aldrich) = Beta3) or vehicle (0.5% carboxymethyl cellulose in sterilized water)=vehicle) by gavage at ZT10 and sacrificed at ZT16.

Mouse kidney after systemic endotoxin challenge

Project description:8 week-old male C57BL6J mice were given Gram-negative endotoxin (LPS O111:B4, 10 mg/kg) intraperitoneally at time 0. 18 hrs thereafter, they were administered 10 ml/kg 0.9% saline. Mice were sacrificed at 0, 18, or 42 hrs after LPS challenge. Kidneys were immediately collected into TRIzol for RNA preparation. Renal function was measured on blood collected at the time of tissue harvest At t=0hr, mice had normal baseline renal function. At t=18hr, mice exhibited early renal injury, At t=42hr, mice had either recovered normal renal function or had persistent renal injury. We collected kidneys from 3 mice per time point. For the 42 hr time point, we collected kidneys from 3 mice with recovered renal function and kidneys from 3 mice with persistent renal injury. Mouse kidneys selected at successive stages of renal injury and recovery following systemic LPS challenge and volume resuscitation following LPS challenge.

High-protein intake eliminates the weight loss-induced improvement in insulin sensitivity

Project description:The purpose of this study was to conduct a randomized-controlled trial to evaluate the effect of a high-protein (HP) diet weight loss (WL) on changes in body composition, insulin sensitivity and skeletal muscle gene expression profile in postmenopausal women who were obese and randomized to one of three dietary intervention groups: 1) a weight maitenance group, 2) a weight loss group (normal protein intake, 0.8 g protein/kg body weight per day) and 3) a weight loss group (high protein intake, 1.2 g protein/kg body weight per day) and studies before and after they lost 10% of their body weight (WL groups) or a time-matched weight maintenacne period.

Transcription profiling of mouse jejunum detached peyers patch from mice orally administered lactoperoxidase (LPO) to study influence of bovine LPO on the digestive tract.

Project description:Lactoperoxidase (LPO) is a component of milk and other external secretions. Recently, we found antiinflammatory effect of orally administered LPO in mouse model of influenza virus-induced pneumonia. In order to study influence of bovine LPO on the digestive tract as its possible target organ, we performed comprehensive gene expression analysis of the mouse small intestine using GeneChip microarray to compare the effect of LPO with that of water or bovine serum albumin (BSA). We observed that 3 h after single ingestion of LPO the levels of 78 gene expression are upregulated and those of 9 gene expressions are downregulated. Within most changed genes, 5 upregulated and 1 downregulated genes such as FK506 binding protein 5 (FKBP5) and serum/glucocorticoid regulated kinase (SGK) are known to be transcriptionally modulated by glucocorticoid. This result suggests that ingested LPO modulates gene expressions in the small intestine in a glucocorticoid-like manner and this activity may link to its systemic antiinflammatory effects. Experiment Overall Design: Mice were orally administered 200 microL of water (n=3), bovine serum albumin (BSA, 2.5 g/kg body weight, n=3), or bovine lactoperoxidase (LPO, 2.5 g/kg body weight, n=3). Three hours after administration, comprehensive gene expressions of jejunum detached payer's patch were analysed for comparison of LPO administration with water or BSA administration.

Exosomal miRNA signatures of amniotic fluid in mice

Project description:To investigate the exosomal miRNA changes under the inflammatory reaction, LPS (100 μg/kg body weight) was intraperitoneally injected into the mice at 15 days of pregnancy. Premature births has been found after approximately 48 h of treatment. When bleeding found in vagina, the uterus and other embryo without breaking water were selected in asepsis condition. The amniotic fluid were selected and isolated exosome to analyze the expression of miRNAs compared with cesarean sections.

Project description:Acute effects caused by the non-genotoxic carcinogen and peroxisome proliferator (PP) diethylhexylphthalate (DEHP) in the mouse liver Mice (n = 6) were dosed by oral gavage (10 ml/kg body weight) with the non-genotoxic carcinogen diethylhexylphthalate (DEHP), every 24 h for 3 days (1150 mg/kg/day), or with an equivalent volume of vehicle control (corn oil).

gene expression of ventral prostate in rat

Project description:Gene expression microarray analysis was performed on ventral prostate from normal adult rats, and adult rats treated BPA for 4 weeks(10 animals per group). Animals of 4 groups were treated with bisphenol-A (0,10, 30, or 90 ug/kg, i.g., daily) for 4 weeks, and the dosing volume is 10 ml/kg body weight. In this experiment, we only selected samples from two doses(0 and 10µg/kg) to analyze.

Dnase1l3 enhances antitumor immunity and suppresses tumor progression [bulk RNAseq]

Project description:For the chronic inflammation-related colon cancer model (AOM/DSS-colon cancer model), 3-month-old Dnase1l3 WT and KO mice were injected with AOM (8 mg/kg, body weight). One week later, mice were challenged with 2.5% DSS water for 7 days followed by a 14-day recovery with regular drinking water for three cycles. Body weight, rectal bleeding and diarrhea were monitored during the entire experiment. Mice with more than 25% weight loss were removed during the experiment. For the AOM model, 2-month-old Dnase1l3 WT and KO mice were injected intraperitoneally with AOM (8 mg/kg, body weight). Colon tissues were isolated 9 hours, or five days after injection. All animal experiments were conducted in accordance with guidelines of NIEHS/NIH Animal Care and Use Committee.
