In this paper, we describe the synthesis, physicochemical characterization, drug release kinetics and preliminary biological evaluation of several N-(2-hydroxypropyl)methacrylamide (HPMA)-based polymer-retinoid conjugates designed for solid tumor immunotherapy. The conjugates are supposed to inhibit the immunosuppressive activity of myeloid-derived suppressor cells (MDSC) accumulated in the solid tumor microenvironment. All-trans retinoic acid (ATRA) was derivatized to hydrazide (AtrHy) and then attached to the polymer backbone via a spacer that is stable at the normal pH of blood (7...

Neuromedin B (NB) and gastrin-releasing peptide (GRP) are bombesin-like peptides, found in the gastrointestinal tube and pancreas, among other tissues. Consistent data proposed that GRP stimulates insulin secretion, acting directly in pancreatic cells or in the release of gastrointestinal hormones that are incretins. However, the role of NB remains unclear. We examined the glucose homeostasis in mice with deletion of NB receptor (NBR-KO). Female NBR-KO exhibited similar fasting basal glucose with lower insulinemia (48...

OBJECTIVE: Sodium tissue content by Na magnetic resonance imaging (Na-MRI) has been validated in experimental and human studies. SGLT-2 inhibition blocks the reabsorption of glucose and, in parallel, of sodium in the proximal tubular cells in a 1:1 fashion. We hypothesized that SGLT-2 inhibition in patients with type 2 diabetes leads to decreased tissue sodium content due to its pharmacological action. DESIGN AND METHOD: In a prospective, double blind, placebo controlled, cross-over trial 59 patients (61 ± 7...

Protein interactions play significant roles in complex diseases. We analyzed peripheral blood mononuclear cells (PBMC) transcriptome using a multi-method strategy. We constructed a tissue-specific interactome (T2Di) and identified 420 molecular signatures associated with T2D-related comorbidity and symptoms, mainly implicated in inflammation, adipogenesis, protein phosphorylation and hormonal secretion. Apart from explaining the residual associations within the DIAbetes Genetics Replication And Meta-analysis (DIAGRAM) study, the T2Di signatures were enriched in pathogenic cell type-specific regulatory elements related to fetal development, immunity and expression quantitative trait loci (eQTL)...

Momordica charantia has been used to treat a variety of diseases, including inflammation, diabetes and cancer. A cucurbitane‑type triterpenoid [(19R,23E)‑5β, 19‑epoxy‑19‑methoxy‑cucurbita‑6,23,25‑trien‑3 β‑o‑l] previously isolated from M. charantia was demonstrated to possess significant cytotoxicity against cancer cells. The current study investigated the effects of this compound (referred to as compound K16) on diabetes using an alloxan‑induced diabetic mouse model. C57BL/6J mice were intraperitoneally injected with alloxan (10 mg/kg body weight), and those with blood glucose concentration higher than 10 mM were selected for further experiments...

All forms of diabetes mellitus are characterized by chronic hyperglycemia resulting in the development of a number of microvascular and macrovascular pathologies. Diabetes is also associated with changes in brain microvasculature, leading to dysfunctions and ultimately disruption of the blood-brain barrier (BBB). These changes are correlated with a decline in cognitive function. In diabetes, BBB damage is associated with increased oxidative stress and reactive oxygen species (ROS). This occurs because of the increased oxidative metabolism of glucose caused by hyperglycemia...

Transplantation of islet allografts into type 1 diabetic recipients usually requires multiple pancreas donors to achieve insulin independence. This adds to the challenges of immunological monitoring of islet transplantation currently relying on surrogate immune markers in peripheral blood. We investigated donor origin and infiltration of islets transplanted in the liver of a T1D patient who died of hemorrhagic stroke four months after successful transplantation with two intraportal islet grafts combining six donors...

Heat stress in hot seasons is a major problem in poultry production, particularly in humid areas. The aim of this study was to determine the pharmacodynamics of betaine on the blood and cecal short chain fatty acid profile in meat-type ducks exposed to heat stress. Three-hundred-sixty meat-type ducks (Anas platyrhynchos domesticus) were randomly allocated into 4 treatments: C (heat stress control without betaine), T1 (700 ppm betaine), T2 (1,000 ppm betaine), and T3 (1,300 ppm betaine). Each treatment had 6 replicated pens with 15 meat-type ducks per pen...

Acylation of ghrelin is mediated by ghrelin O-acyltansferase (GOAT). Exogenous acylated ghrelin (AG) stimulates growth hormone (GH) and food intake. In non-pregnant (NP) animals, the GOAT-ghrelin-GH axis prevents hypoglycemia caused by caloric restriction (CR). In humans, maternal malnutrition challenges glucose metabolism, which is a key determinant of fetal health. To clarify the role of AG and GH, we compared effects of CR on the GOAT-ghrelin-GH axis in pregnant (P) and NP mice. C57BL/6 wild type (WT) and GOAT knock-out (KO) P and NP mice were freely fed (FF) or subjected to 50% CR for one week...

Lactic acidosis (LA) is a marker for mortality in severe malaria, but the mechanisms that lead to LA in the different types of severe malaria and the extent to which LA-associated mortality differs by type of severe malaria are not well described. We assessed the frequency of LA in children admitted to Mulago Hospital, Kampala, Uganda with cerebral malaria (CM, n = 193) or severe malarial anemia (SMA, n = 216). LA was compared to mortality and measures of parasite biomass and sequestration (P. falciparum histidine-rich protein-2 (PfHRP2) concentration, platelet count), and to a measure of systemic tissue oxygen delivery (hemoglobin level)...
