BACKGROUND: Glutamine aminoacid regulates insulin exocytosis from pancreatic β-cells. Liraglutide is a glucagon-like peptide-1 (GLP-1) analogue that has fascinated function in inhibiting β-cell apoptosis and preserving pancreatic β-cell mass. The present study investigated the benefit of adding glutamine to a regimen of liraglutide in diabetic rats focusing on their role in increasing insulin production and upregulation of the expression of sodium-dependent neutral aminoacid transporter-2 (SNAT2)...

Endothelial cells (ECs) maintain the structure and function of blood vessels and are readily exposed to exogenous and endogenous toxic substances in the circulatory system. Bone marrow-derived endothelial progenitor cells (EPCs) circulate in the blood and differentiate to EC, which are known to participate in angiogenesis and regeneration of injured vessels. Dysfunction in EPC contributes to cardiovascular complications in patients with diabetes, but the precise molecular mechanisms underlying diabetic EPC abnormalities are not completely understood...

Twenty-eight lactating Yorkshire and Yorkshire × Landrace primiparous sows were used to test the hypothesis that feeding a diet with reduced CP concentration and supplemented with crystalline amino acids (CAA) does not decrease milk protein yield and litter growth but improves apparent N utilization for milk protein production. Sows were assigned to 1 of 2 dietary treatments: [1] Control (CON; 16.2% CP; analyzed content) or [2] Low CP with CAA to meet estimated requirements of limiting amino acids (LCP; 12...

Purpose We explored whether advanced magnetic resonance (MR) imaging techniques could grade oligodendrogliomas. Methods Forty patients (age 9-61 years) with oligodendroglial tumors were selected. There were 23 patients with World Health Organization grade II (group 1) and 17 patients with grade III (group 2) tumors. Apparent diffusion coefficient (ADC) maps were calculated by b values of 0 and 1000 s/mm2 . Dynamic susceptibility contrast (DSC) images were obtained during the first pass of a bolus of gadolinium-based contrast...

Type 3 diabetes mellitus has been coined to describe an alternative pathologic pathway of Alzheimer's disease (AD). The insulin resistance and impaired insulin signaling seen on positron-emission tomography scans in the brain of those affected by AD support this disease hypothesis. Two products-the medical food caprylidene (Axona) and coconut oil-seek to target the underlying pathology of type 3 diabetes mellitus by providing an alternative fuel source in the brain. Rather than improving glucose utilization, these two products seek to supply ketone bodies in sufficient quantities to pass through the blood-brain barrier and provide an alternative energy source to glucose...

BACKGROUND: Spinal cord injury (SCI) triggers a robust neuroinflammatory response that governs secondary injury mechanisms with both degenerative and pro-regenerative effects. Identifying new immunomodulatory therapies to promote the supportive aspect of immune response is critically needed for the treatment of SCI. We previously demonstrated that SCI results in acute and permanent depletion of the neuronally derived Neuregulin-1 (Nrg-1) in the spinal cord. Increasing the dysregulated level of Nrg-1 through acute intrathecal Nrg-1 treatment enhanced endogenous cell replacement and promoted white matter preservation and functional recovery in rat SCI...

Antimicrobial drug resistance, a global concern, has been increasing unpredictably in microorganism causing human infections specially among Gram negative non-fermenting Pseudomonas spp. Carbapenems, a beta lactam antibiotics, are the most potent and effective drug usually kept reserved for treating the multi-drug resistant Psedomonas spp and other infections caused by organisms producing Extended Spectrum Beta Lactamase (ESBL) and AmpC. Clinical utility of carbapenem will reduce when resistant bacteria evolve due to production of carbapenem hydrolyzing Metallo-β-lactamase (MBL) which confers high-level resistance to all beta-lactam antibiotics except aztreonam...

BACKGROUND: Elevated INR is a marker of poor outcome but not necessarily bleeding or clinical coagulopathy in injured children. Conversely, children with traumatic brain injury (TBI) tend to be hypercoagulable based on rapid thromboelastography (rTEG) parameters. Many clinicians continue to utilize INR as a treatment target. METHODS: Prospective observational study of severely-injured children age<18 with rTEG on arrival and daily thereafter for up to 7 days...

BACKGROUND: With increasing global use of intravenous immunoglobulin (IVIG), there is interest in its appropriate usage. Efforts to regulate IVIG usage have primarily taken the form of organizational interventions implemented in hospitals to monitor and improve physician prescribing. Similar interventions have proven effective in reducing the inappropriate and total hospital usage of other blood products, but their efficacy on IVIG use is less understood. Thus, we performed a systematic review of studies reporting the change in inappropriate IVIG use following such interventions in hospitals or regions...

INTRODUCTION: Hemorrhage is the leading cause of death on the battlefield. Development of chitosan- and kaolin-based hemostatic agents has improved hemorrhage control options. Sparse data exists on the use of these agents in the prehospital, combat setting. We describe recent use of these agents and compare patients receiving hemostatic to the baseline population. METHODS: We used a series of emergency department (ED) procedure codes to identify patients within the Department of Defense Trauma Registry (DODTR) from January 2007 to August 2016...

INTRODUCTION: Diagnosing BCR-ABL negative myeloproliferative neoplasms (MPN) may be challenging due to overlapping features and lack of robust discriminatory parameters, especially between essential thrombocythemia (ET) and prefibrotic myelofibrosis (MF). Circulating immature hematopoietic cells are variably present in polycythemia vera (PV), ET, and MF. The C-type lectin hMICL is aberrantly expressed on hematopoietic stem cells in the majority of acute myeloid leukemia patients. However, the hMICL expression in MPN, having varying propensity of leukemic transformation, is unsettled...

Sex-related differences in metabolic and neuroendocrine response to exercise in individuals without diabetes have been well established. Men and women differ in fuel selection during exercise, in which women rely to a greater extent on fat oxidation, whereas males rely mostly on carbohydrate oxidation for energy production. The difference in fuel selection appears to be mediated by sex-related differences in hormonal (including catecholamines, growth hormone, and estrogen) response to different types and intensities of exercise...

In severe trauma and hemorrhage the early and empiric use of fresh frozen plasma (FFP) is associated with decreased morbidity and mortality. However, utilization of FFP comes with the significant burden of shipping and storage of frozen blood products. Dried or lyophilized plasma (LP) can be stored at room temperature, transported easily, reconstituted rapidly with ready availability in remote and austere environments. We have previously demonstrated that FFP mitigates the endothelial injury that ensues after hemorrhagic shock (HS)...

Background: Lactic acid is being routinely used as a marker of hypoxia in aircrash investigation. Since lactic acid estimation as a marker of hypoxia in postmortem samples for aircrash investigation is prone to many interfering factors, like the postmortem production and hemolysis. A study was carried out to evaluate other hypoxia markers other than lactic acid which could be later added as markers of hypoxia in postmortem investigations of aircraft accidents. Methods: 25 healthy males of age 20-40 yrs volunteered participants were subjected to an simulated altitude of 15,000 ft for 30 min and the mean plasma concentration of Hypoxia Inducing Factor 1α (HIF 1α), Erythropoietin (EPO), Vascular Endothelial Growth Factor (VEGF) and lactic acid (LA) were analyzed from their venous blood sample collected at 4 intervals viz...
