Lymphatic leakage can be seen as a detrimental phenomenon associated with fluid retention and deposition as well as gain of weight. Moreover, lymphatic dysfunction is associated with an inflammatory environment and can be a substrate for other health conditions. A number of treatments can ameliorate lymphatic vasculature: natural substances have been used as treatment options particularly suitable for their consolidated effectiveness and safety profile. Here we report the protective effect of AdipoDren®, an association of a series of plant-derived natural complexes, on lymphatic endothelium permeability promoted by interleukin-1 beta (IL-1β) and the associated molecular mechanisms...

Human Glutaredoxin3 (hGLRX3), which encodes a 37.4 kDa protein, possesses an N-terminal Trx homology domain followed by two tandem repeats of Grx domains. GLRX3 is expressed in many tissues and plays important roles in iron metabolism, antioxidant effect, cell proliferation and development, regulation of immune reaction, and tumorigenesis. The mechanisms underlying the biological function of GLRX3 are still not clear. To facilitate the functional research of GLRX3, in this study, monoclonal antibodies (MAbs) against hGLRX3 were produced by using purified prokaryotic recombinant 6His-hGLRX3 fusion protein as the immunogen...

The objective of this study was to investigate the changes in oxidative stress (OS) and circulating regulatory T cells (Tregs) of the immune system in CF-VAD patients with or without infection. We recruited 16 CF-VAD patients (5 with infection and 11 without infection) and 7 healthy volunteers. Generation of reactive oxygen species (ROS) from lymphocytes, superoxide dismutase (SOD) in erythrocyte, total antioxidant capacity (TAC) and oxidized low density lipoprotein (oxLDL) in plasma were measured. Circulating Tregs were evaluated by flow cytometry...

We report the facile and non-covalent preparation of gold nanoparticles (AuNPs) stabilized by an antiparkinson codrug based on lipoic acid (LA). The obtained AuNPs appear stable in both dimethyl sulfoxide and fetal bovine serum and able to load an amount of codrug double the weight of gold. These NPs were demonstrated to be safe and biocompatible towards primary human blood cells and human neuroblastoma cells, one of the most widely used cellular models to study dopaminergic neural cells, therefore are ideal drug carriers for difficult to solubilize molecules...

BACKGROUND: Hyperbaric oxygen (HBO) therapy may improve cholestasis, increase hepatic regeneration, and decrease oxidative stress in liver. In this study, we aimed to investigate the effects of HBO therapy on hepatic oxidative stress parameters, such as total thiol groups (T-SH), protein carbonyl (PCO), and total antioxidant capacity (TAC) as well as the predictive value of the noninvasive biochemical marker, sialic acid (SA), and prolidase activity in bile duct ligation (BDL)-induced oxidative damage and fibrosis in rats...

The regulation of the extracellular matrix (ECM) by mechanical stress is of interest as the ECM is essential in the development of pelvic organ prolapse. In the present study, the effect of overexposure to mechanical stress on the ECM, and the probable underlying mechanisms in cultured human uterosacral ligament fibroblasts (hUSLFs), was explored. Mechanical stress has an effect on oxidation‑antioxidation products in parametrial ligament fibroblasts. Thus, hUSLFs were incubated with different concentrations of hydrogen peroxide to elucidate any potential interactions...

Owing to statin's immune modulatory, anti-inflammatory, antioxidant, antithrombotic and endothelial function actions, they are widely used in the critical care settings in diverse disease scenarios. We aim to explore the evidence to globalize the utilization of statins in the intensive care practice for different indications. We carried out a search of the PubMed, Cochrane and EMBASE databases up to January 2016. We included review articles, meta-analyses, and original trials on the effects of statin therapy in the intensive care unit (ICU) combining the following MESH terms: 'satins', 'intensive care, 'cardiac surgery', 'sepsis', 'acute respiratory distress syndrome' 'pneumonia', subarachnoid hemorrhage', traumatic brain injury and 'critical illness'...

To investigate the effect of glycitein, a synthetic soybean isoflavone (ISF), on the intestinal antioxidant capacity, morphology, and cytokine content in young piglets fed oxidized fish oil, 72 4-d-old male piglets were assigned to three treatments. The control group was fed a basal diet containing fresh fish oil, and the other two groups received the same diet except for the substitution with the same dosage of oxidized fish oil alone or with ISF (oxidized fish oil plus ISF). After 21 d of feeding, supplementation of oxidized fish oil increased the levels of malondialdehyde (MDA), oxidized glutathione (GSSG), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-2 (IL-2), nuclear factor κ B (NF-κB), inducible nitric oxide synthase (iNOS), NO, and Caspase-3 in jejunal mucosa, and decreased the villous height in duodenum and the levels of secretory immunoglobulin A (sIgA) and IL-4 in the jejunal mucosa compared with supplementation with fresh oil...

Oxidative stress and diabetes have a tendency to alter protein, lipid, and DNA moieties. One of the strategic methods used to reduce diabetes-associated oxidative stress is to inhibit the carbohydrate-digesting enzymes, thereby decreasing gastrointestinal glucose production. Plant-derived natural antioxidant molecules are considered a therapeutic tool in the treatment of oxidative stress and diabetes. The objective of this study was to identify tartary buckwheat rice flavonoids and evaluate the effect of in vitro digestion on their antioxidant and antidiabetic properties...

Polyamines (PAs) and nitric oxide (NO) are vital signals in modulating plant response to abiotic stress. However, to our knowledge, studies on the relationship between NO and PAs in response to cold stress in tomato are limited. Accordingly, in this study, we investigated the effects of putrescine (Put) and spermidine (Spd) on NO generation and the function of Spd-induced NO in the tolerance of tomato seedling under chilling stress. Spd increased NO release via the nitric oxide synthase (NOS)-like and nitrate reductase (NR) enzymatic pathways in the seedlings, whereas Put had no such effect...

Selenium (Se) is vital for health because of its antioxidative and anti-inflammation functions. The aim of this study was to determine if dietary selenium could inhibit the rat lung injury induced by ambient fine particulate matter (PM2.5). Sprague-Dawley rats were randomly allocated in seven groups (n = 8). The rats in PM2.5 exposure group were intratracheally instilled with 40 mg/kg of body weight (b.w.) of PM2.5 suspension. The rats in Se prevention groups were pretreated with 17.5, 35, or 70 μg/kg b...

The ingestion of whole wheat products is responsible for the prevention of a number of chronic diseases. The aim of this study is to characterize the molecular properties of a novel wheat germ-derived antioxidant peptide (AOP) in protection against high glucose-induced oxidative stress in vascular smooth muscle cells (VSMCs). AOP (amino acid sequence AREGETVVPG) was isolated from wheat germ albumin using dual-enzymatic hydrolysis/separation, followed by MS/MS. The in vitro IC50 value for Fe(2+) chelation was 0...

BACKGROUND: Renal ischemia-reperfusion (IR) contributes to the development of acute renal failure (ARF). Oxygen free radicals are considered to be the principal components involved in the pathophysiological tissue alterations observed during renal IR. OBJECTIVES: In this study, we compared the effects of melatonin (MEL) and erythropoietin (EPO), both known antioxidant and anti-inflammatory agents, on IR-induced renal injury in rats. MATERIALS AND METHODS: Wistar albino rats were unilaterally nephrectomized and then subjected to 45 minutes of renal pedicle occlusion followed by 24 hours of reperfusion...

The interaction of elevated [CO2] and water stress will have an effect on the adaptation of durum wheat to future climate scenarios. For the Mediterranean basin these scenarios include the rising occurrence of water stress during the first part of the crop cycle. In this study, we evaluated the interactive effects of elevated [CO2] and moderate to severe water stress during the first part of the growth cycle on physiological traits and gene expression in four modern durum wheat genotypes. Physiological data showed that elevated [CO2] promoted plant growth but reduced N content...
