Uncoupling protein 2 (UCP2) plays critical roles in energy metabolism and cell survival. Previous investigations showed that UCP2 regulated the production of extracellular matrix and renal fibrosis. However, little is known about UCP2 in acute kidney injury. Here, we used UCP2 knockout mice to investigate the role of UCP2 in AKI model generated by renal ischemia/reperfusion (I/R) injury. The UCP2 global knockout mice were born and growth normal without kidney histological abnormality or renal dysfunctions. As compared with littermates, deletion of UCP2 exacerbated I/R-induced AKI while increase of UCP2 by conjugated linoleic acid (CLA) attenuated I/R injury...

A field experiment with thin-layer capping was conducted in the Grenland fjords, Norway, for remediation in situ of mercury and dioxin-contaminated sediments. Experimental fields at 30 and 95 m depth were capped with (i) powdered activated carbon (AC) mixed with clay (AC+cla`y), (ii) clay, and (iii) crushed limestone. Ecological effects on the benthic community and species-feeding guilds were studied 1 and 14 months after capping, and a total of 158 species were included in the analyses. The results show that clay and limestone had only minor effects on the benthic community, while AC+clay caused severe perturbations...

PURPOSE: Conventional laparoscopic appendectomy (CLA) has been considered the standard for the treatment of acute appendicitis. Recently, single incision laparoscopic appendectomy (SILA) has become an alternative option. There are few reports on the results of SILA performed by residents during the training period. The present study, we report our residents' experience. MATERIALS AND METHODS: We reviewed clinical characteristics and outcomes of 1005 patients who underwent appendectomy between October 2013 and April 2016...

Diets containing high n-3 polyunsaturated fatty acids (PUFA) decrease inflammation and the incidence of chronic diseases including cardiovascular disease and nonalcoholic fatty liver disease while trans-fatty acids (TFA) intake increases the incidence of these conditions. Some health benefits of n-3 PUFA are mediated through the impact of their oxygenated metabolites, i.e. oxylipins. The TFA, trans-10, cis-12-conjugated linoleic acid (CLA; 18:2n-6) is associated with adipose tissue (AT) inflammation, oxidative stress, and wasting...

IL-31 is a recently identified cytokine with a well-defined role in the pathogenesis of pruritus. IL-31, whose production is induced by IL-4 and IL-33, binds a heterodimeric receptor (R) composed of the exclusive IL-31RA chain and the shared oncostatin M R. Signaling through the IL-31R involves the MAPK, PI3K/AKT and Jak/STAT pathways. Different variants and isoforms of IL-31RA with different signaling activities have been identified. IL-31 is produced predominantly by circulating Th2 lymphocytes and skin-homing CLA(+)CD45RO(+) T cells...

BACKGROUND: Replacing concentrates with forages in the diet of finishing cattle to satisfy societal demands and for economic reasons is a target for beef farmers, but this change may affect meat acceptance. In the Mediterranean area, young bulls are usually finished on concentrates (Conventional beef). Alternatively, steers can be finished on grass with supplements (G-supp); however, if carcasses are too lean, meat quality may be negatively affected. To increase fat deposition, grazing steers were finished on a total mixed ration composed of alfalfa hay and corn (TMR)...

Blood to skin recirculation could play a role in the pathogenesis of psoriasis. To investigate this possibility we dissected the phenotype of circulating T cells in psoriasis patients, calculated the correlation the clinical parameters of the disease and performed a parallel bioinformatics analysis of gene expression data in psoriatic skin. We found that circulating CCR6(+) CD4(+) TEM and TEFF cells significantly correlated with systemic inflammation. Conversely, the percentage of CXCR3(+) CD4(+) TEM cells negatively correlated with the severity of the cutaneous disease...

Fusarium graminearum is the major causal agent of fusarium head blight in wheat, a serious disease worldwide. Linoleic acid isomerase (LAI) catalyses the transformation of linoleic acid (LA) to conjugated linoleic acid (CLA), which is beneficial for human health. We characterised a cis-12 LAI gene of F. graminearum (FGSG_02668; FgLAI12), which was downregulated by salicylic acid (SA), a plant defence hormone. Disruption of FgLAI12 in F. graminearum resulted in decreased accumulation of cis-9,trans-11 CLA, enhanced sensitivity to SA, and increased accumulation of LA and SA in wheat spikes during infection...

The aim was to determine the effect of substituting pumpkin seed cake (PSC) or extruded linseed (ELS) for soya bean meal in goats' diets on milk yield, milk composition and fatty acids profile of milk fat. In total, 28 dairy goats were divided into three groups. They were fed with concentrate mixtures containing soya bean meal (Control; n=9), ELS (n=10) or PSC (n=9) as main protein sources in the trial lasting 75 days. Addition of ELS or PSC did not influence milk yield and milk gross composition in contrast to fatty acid profile compared with Control...

The glucagon-like peptide-1 receptor (GLP-1R) is a cla B G protein-coupled receptor that is a major therapeutic target for the treatment of type 2 diabetes. Activation of this receptor promotes insulin secretion and blood glucose regulation. The GLP-1R can initiate signaling through several intracellular pathways upon activation by GLP-1. GLP-1R ligands that preferentially stimulate subsets among the natural signaling pathways ("biased agonists") could be useful as tools for elucidating the consequences of specific pathways and might engender therapeutic agents with tailored effects...

Conjugated linoleic acids (CLAs) have been found to have beneficial effects on human health when used as dietary supplements. However, their availability is limited because pure, chemistry-based production is expensive, and biology-based fermentation methods can only create small quantities. In an effort to enhance microbial production of CLAs, four genetically modified strains of the oleaginous yeast Yarrowia lipolytica were generated. These mutants presented various genetic modifications, including the elimination of β-oxidation (pox1-6∆), the inability to store lipids as triglycerides (dga1∆ dga2∆ are1∆ lro1∆), and the overexpression of the Y...

In this work the aggregation behavior of t10,c12 Conjugated linoleic acid (t10,c12-CLA) is presented for first time. The results show a c.m.c. of 25μM at pH 8 and 25°C. The encapsulation process with cyclodextrins (CDs) presented a 1:1 stoichiometry in all cases studied but the complexation constants were strongly dependent on the type of CDs used, the pH and temperature. Hydroxypropyl-beta-Cyclodextrin (HPβCD) was the best CD studied for encapsulating t10,c12-CLA. The resulting t10,c12-CLA-HPβCD complex showed a very high dependency on pH, which explains why a pKa of 4...

The objective of this experiment was to follow the time-course changes of the milk fatty acids (FA) and particularly conjugated linoleic acid (CLA), n-3, and n-6 FA in response to feeding whole rolled safflower seed (SS). Eighteen cows were blocked by milk production, days in milk, and parity, and randomly assigned to 1 of 3 diets by replacing whole cottonseed with SS. The control diet contained no SS (SS0), whereas the other diets contained 3% of dry matter as SS (SS3) or 6% SS (SS6). The study was conducted for 8 wk...

Active transposable elements (TEs) may result in divergent genomic insertion and abundance patterns among conspecific populations. Upon secondary contact, such divergent genetic backgrounds can theoretically give rise to classical Dobzhansky-Muller incompatibilities (DMI), thus contributing to the evolution of endogenous genetic barriers and eventually cause population divergence. We investigated differential TE abundance among conspecific populations of the non-biting midge Chironomus riparius and evaluated their potential role in causing endogenous genetic incompatibilities between these populations...

Innate lymphoid cells (ILC) are members of a heterogeneous family with a lymphoid origin that mimics the T helper (Th) cytokine profile. ILC are involved in early effector cytokine-mediated responses during infections in peripheral tissues. ILC also play an important role in chronic skin inflammatory diseases, including psoriasis. Although classical ILC express CD127, it has been recently reported that the presence of non-classical CD127(-) ILC populations and an early ILC precursor (EILP) CD127(low). ILC development has predominately been investigated in mouse models...
