Glycoxidation of protein may lead to develop diabetes. In the present study, different concentrations of 2-deoxy d-ribose (2-dRib) were used to modify human serum albumin (HSA). Nitro Blue Tetrazolium (NBT) assay results showed that yield of the fructosamine content was directly proportional to the concentration of 2-dRib. UV and fluorescence spectroscopy results showed an increment in hyperchromicity and decrease in fluorescence intensity of 2-dRib modified HSA as compared to native HSA. Further secondary structural changes were confirmed by UV-circular dichroism (UV-CD) and Fourier transform infrared spectroscopy (FT-IR)...

Acute hypothermia treatment (HT) is the only clinically established intervention following neonatal hypoxic-ischemic brain injury. However, almost half of all cooled infants still die or suffer from long-lasting neurological impairments. Regenerative therapies, such as mesenchymal stem cells (MSC) appear promising as adjuvant therapy. In the present study, we hypothesized that HT combined with delayed MSC therapy results in augmented protection, improving long-term neurological outcome. Postnatal day 9 (P9) C57BL/6 mice were exposed to hypoxia-ischemia followed by 4 hours HT...

OBJECTIVE: Histone deacytylase inhibitors (HDACis) inhibit the deacetylation of the lysine residue of proteins, including histones, and regulate the transcription of a variety of genes. Recently, HDACis have been used clinically as anti-cancer drugs and possible anti-diabetic drugs. Even though HDACis have been proven to protect the cytokine-induced damage of pancreatic beta cells, evidence also shows that high doses of HDACis are cytotoxic. In the present study, we, therefore, investigated the eff ect of HDACis on insulin secretion in a pancreatic beta cell line...

Immune activation and inflammation participate in the progression of chronic heart failure (CHF). Th17 cells and CD4+CD25+ regulatory T (Treg) cells both come from naive Th cells and share reciprocal development pathways but exhibit opposite effects. We hypothesized that the Th17/Treg balance was impaired in patients with CHF, and exercise can improve it. Rats with ischemic cardiomyopathy were prepared by ligaturing the left anterior descending branch of the left coronary artery. Rats in training group were trained with treadmill; Th17 cells increased significantly while Treg cells significantly decreased in s by flow cytometry, and the peripheral blood level of IL-6, IL-17, and TNF-α was obviously elevated by ELISA assay...

PURPOSE: Follistatin levels increase during the course of pregnancy and may play a role in ovarian arrest, reflected by the simultaneous decrease of anti-mullerian-hormone (AMH) levels. The aim of the study was to investigate AMH and follistatin levels during the hormonal window at the beginning of pregnancy. Since both parameters are described as deregulated in polycystic ovarian syndrome (PCOS), subgroup analysis of PCOS patients may additionally elucidate their interplay and effects on ovarian activity...

BACKGROUND: Polymerase δ-interacting protein 2 (Poldip2) is a multifunctional protein that regulates vascular extracellular matrix composition and matrix metalloproteinase (MMP) activity. The blood-brain barrier (BBB) is a dynamic system assembled by endothelial cells, basal lamina, and perivascular astrocytes, raising the possibility that Poldip2 may be involved in maintaining its structure. We investigated the role of Poldip2 in the late BBB permeability induced by cerebral ischemia...

Objectives: RA is an articular chronic inflammatory disease that in a subgroup of patients can also present with extra-articular manifestations (EAMs). Despite intense investigation on this topic, reliable biomarkers for EAMs are lacking. In recent years several ACPAs, including those targeting anti-citrullinated alpha enolase peptide-1 (anti-CEP-1), have been identified in patients with RA. Data about the ability of anti-CEP-1 to predict the development of erosive disease are confliciting and no evidence concerning their possible association with EAMs in RA is currently available...

Toxoplasma gondii is an obligate intracellular parasitic protozoan with a worldwide distribution. The parasites in edible tissues of pigs and oocysts from cats are the major sources of T. gondii infection in humans. However, there are no data from sick pigs in veterinary clinics or from stray cats in Jiangsu Province, eastern China. In total, biological samples from 141 sick pigs and 64 stray cats were collected from this region. The rate of T. gondii infection in sick pigs was 46.81% using a polymerase chain reaction (PCR), and the overall prevalence of toxoplasmosis in stray cats was 34...
