Animal by-products can be recycled and used as sources of essential nutrients. Water-soluble heme iron (WSHI), a functional food additive for supplementing iron, is produced by processing animal blood. In this study, we investigated the effects of dietary supplementation of 3% WSHI and exercise training for 4 weeks on the accumulation of abdominal fat and lipid metabolism in mice fed high-fat diet. Exercise-trained mice had significantly less perirenal adipose tissue, whereas WSHI-fed mice tended to have less epididymal adipose tissue...

BACKGROUND: Data on the effects of coenzyme Q10 (CoQ10) supplementation on metabolic profiles among subjects with polycystic ovary syndrome (PCOS) are scarce. OBJECTIVE: This study was done to evaluate the effects of CoQ10 supplementation on glucose metabolism and lipid profiles in subjects with PCOS. DESIGN, PATIENTS AND MEASUREMENTS: This randomized double-blind, placebo-controlled trial was conducted on 60 women diagnosed with PCOS. Subjects were randomly assigned into two groups to intake either 100 mg CoQ10 supplements (N=30) or placebo (N=30) per day for 12 weeks...

Microorganisms produce a wide spectrum of (phospho)lipases that are secreted in order to make external substrates available for the organism. Alternatively, other (phospho)lipases may be physically associated with the producing organism causing a turnover of intrinsic lipids and frequently giving rise to a remodeling of the cellular membranes. Although potential (phospho)lipases can be predicted with a number of algorithms when the gene/protein sequence is available, experimental proof of the enzyme activities, substrate specificities, and potential physiological functions has frequently not been obtained...

Alteration of mitochondria-associated membranes (MAMs) has been proposed to contribute to the pathogenesis of Alzheimer's disease (AD). We studied herein the subcellular distribution, the processing, and the protein interactome of the amyloid-β protein precursor (AβPP) and its proteolytic products in MAMs. We reveal that AβPP and its catabolites are present in MAMs in cellular models overexpressing wild type AβPP or AβPP harboring the double Swedish or London familial AD mutations, and in brains of transgenic mice model of AD...

Lipids such as ceramides (Cer) and phosphatidylcholines (PC) have been found altered in the plasma of Alzheimer's disease (AD) patients in a number of discovery studies. For this reason, the levels of 6 ceramides and 3 PCs, with different fatty acid length and saturation levels, were measured in the plasma from 412 participants (AD n = 205, Control n = 207) using mass spectrometry coupled with ultra-performance liquid chromatography. After this, associations with AD status, brain atrophy, and age-related effects were studied...

PURPOSE: Endocan is a proteoglycan secreted mainly from endothelial cells. It has been implicated that there is a link between endocan and endothelial dysfunction. Polycystic ovary syndrome (PCOS) is a reproductive and metabolic disease associated with increased risk of cardiovascular events. The aims of this study were to ascertain whether circulating endocan levels are altered in women with PCOS, and whether there is an association between endocan and carotid intima media thickness (cIMT)...

CD14 and Toll-like receptor 4/MD2 (TLR4/MD2) mediate the action of LPS on neutrophils. The anti-CD14 antibody and the TLR4/MD2-antagonist, synthetic lipid IVa (LA-14-PP), are known to inhibit the response of neutrophils to LPS. We studied the role of CD14 in LPS-induced priming of neutrophils for enhanced release of the superoxide anion. The anti-CD14 antibody at much higher concentrations than required to saturate CD14 was required to inhibit priming by LPS. The inhibitory effect of the anti-CD14 antibody was overcome by LPS...

Heterozygosity for a 3-base pair deletion (ΔGAG) in TOR1A/torsinA is one of the most common causes of hereditary dystonia. In this review, we highlight current understanding of how this mutation causes disease from research spanning structural biochemistry, cell science, neurobiology, and several model organisms. We now know that homozygosity for ΔGAG has the same effects as Tor1a(KO) , implicating a partial loss of function mechanism in the ΔGAG/+ disease state. In addition, torsinA loss specifically affects neurons in mice, even though the gene is broadly expressed, apparently because of differential expression of homologous torsinB...

We have developed a simple and effective strategy to prepare an enzymatic membrane by the admixing of a halloysite clay nanotube-lipase complex and a chitosan solution. The loading of 3 wt% lipase into the lumen of halloysite clay nanotubes was enhanced with an electrostatic interaction. 10 wt% of lipase-nanotubes were dispersed in an aqueous chitosan solution and cast as a coating. The enzymatic chitosan-halloysite membranes displayed increased pH, temperature stability and long-term usability for the catalytic decomposition of lipids: 90% of the initial activity was preserved at 80 °C, 70% of the functionality remained at the high pH of 9, and 85% of the activity was sustained after ten continuous cycles of use...

Cancer cells use autophagy to resist poor survival environmental conditions such as low PH, poor nutrients as well as chemical therapy. Nanogels have been used as efficient chemical drug carriers for cancer treatment. However, the effect of nanogels on autophagy is still unknown. Here, we used Rab proteins as the marker of multiple trafficking vesicles in endocytosis and LC3 as the marker of autophagy to investigate the intracellular trafficking network of Rhodamine B (Rho)-labeled nanogels. The nanogels were internalized by the cells through multiple protein dependent endocytosis and micropinocytosis...

Polypoidal choroidal vasculopathy (PCV), the predominant subtype of neovascular age-related macular degeneration in the Asian population, is associated with genetic polymorphism of lipid metabolism. In this study, we performed the untargeted lipidomics approach of ultra-performance liquid chromatography coupled with mass spectrometry (UPLC-MS) to reveal the potential discriminating lipid profile of PCV patients in serum (21 PCV patients and 19 age-matched controls). Unsupervised principal component, supervised orthogonal partial least squares analysis, correlation analysis, and heatmap analysis were performed with the data obtained by UPLC-MS...

Different concentrations of standardized ethanolic extract from the basidiocarps of Tricholoma giganteum Massee (TgEtOH) were screened for hepatoprotective effects in an animal model of rats with nonalcoholic fatty liver disease (NAFLD) fed a high-fat and high-fructose diet. After 4 weeks of treatment with TgEtOH, the relative liver weights, serum lipid concentrations, and biochemical profiles were found to be normal in treated animals compared with those given a standard drug. The macroscopic and histopathological studies clearly indicated that 200 mg/kg of ethanolic extract was effective in ameliorating the abnormalities of NAFLD...

Doxorubicin (DOX) is a well-known cytotoxic agent used extensively as a chemotherapeutic drug to eradicate a wide variety of human cancers. Reactive oxygen species (ROS)-mediated oxidative stress during DOX treatment can induce cardiac, renal, and hepatic toxicities, which can constrain its use as a potential cytotoxic agent. The present work investigates the antioxidant potential of naringenin (NAR) against DOXinduced toxicities of a Dalton's lymphoma ascites (DLA) tumor-bearing mouse model. Mice were randomized into four groups: a negative control, positive control, DOX (2...

We set out to determine the effect of oxycarotenoid lutein on reducing cardiac and renal toxicity induced by doxorubicin (DXR). We started with oral administration in rats of lutein for 15 d before administering DXR (30 mg/kg body weight, intraperitoneally, in a single dose). Animals in all groups were sacrificed 24 h after DXR administration. Serum markers of cardiac injury lactate dehydrogenase, creatine phosphokinase, serum glutamate oxaloacetate transaminase, and serum glutamate pyruvate transaminase increased drastically after DXR but decreased after lutein treatment (p < 0...
