Patients with non-transfusion-dependent thalassemia (NTDT) are at risk of developing brain ischemia. Transcranial Doppler (TCD) has been established as a useful screening tool of cerebrovascular disease in patients with sickle cell disease. Proteins neuron specific enolase (NSE) and S100B are biomarkers that reflect CNS injury. The purpose of this study is to evaluate cerebral vessel vasculopathy and brain damage in NTDT patients using non-invasive methods as TCD and measurement serum levels of NSE and S100B...

Background: Beetroot juice (BJ) is rich in inorganic nitrates and has proved effective at increasing blood nitric oxide (NO) levels. When used as a supplement BJ has shown an ergogenic effect on cardiorespiratory resistance exercise modalities, yet few studies have examined its impact on high intensity efforts. Objective: To assess the effects of BJ intake on anaerobic performance in a Wingate test. Methods: Fifteen trained men (age 21.46 ± 1.72 years, height 1.78 ± 0.07 cm and weight 76.90 ± 8.67 kg) undertook a 30-s maximum intensity test on an inertial cycle ergometer after drinking 70 mL of BJ (5...

OBJECTIVE: Glycogen in astrocyte endfeet contributes to maintenance of low extracellular glutamate and K+ concentrations around synapses. Sleep deprivation (SD), a common migraine trigger induces transcriptional changes in astrocytes reducing glycogen breakdown. We hypothesize that when glycogen utilization cannot match synaptic energy demand, extracellular K+ can rise to levels that activate neuronal pannexin-1 channels and downstream inflammatory pathway, which might be one of the mechanisms initiating migraine headaches...

We quantify the impact of several variables including site of blood draw, delay in measurement, and use of the cyanide antidote hydroxocobalamin on detection of both normal (<2 mmol/L) and elevated (>6 mmol/L) human plasma lactate. An in vivo study assessed effects of venous or arterial origin of blood samples. Two in vitro studies assessed the effect of a 2 h delay in measuring plasma lactate concentrations, as well as the interference of low (100 μmol/L) and high (300 μmmol/L) plasma hydroxocobalamin concentrations on detecting normal and elevated levels of lactate...

Recent studies have shown that periodontitis accelerates the progression of obesity-associated metabolic diseases. Thus, we examined the influence of periodontitis on serum biochemical parameters of metabolic disease in a diet-induced obesity (DIO) rat. First, we established the DIO model using ten male rats fed with either basal diet (lean group) or high-fat diet (DIO group) for 12 weeks. Second, to examine the interaction between periodontitis and obesity, we divided 24 DIO rats into the following four groups...

Attempts to alter intestinal dysbiosis via administration of probiotics have consistently shown that colonization with the administered microbes is transient. This study sought to determine whether provision of an initial course of Bifidobacterium longum subsp. infantis (B. infantis) would lead to persistent colonization of the probiotic organism in breastfed infants. Mothers intending to breastfeed were recruited and provided with lactation support. One group of mothers fed B. infantis EVC001 to their infants from day 7 to day 28 of life (n = 34), and the second group did not administer any probiotic (n = 32)...

Butyrate can improve gut functions, whereas histone deacetylase inhibitors might alleviate neurocognitive alterations. Our aim was to assess whether oral butyrate could modulate brain metabolism and plasticity and if this would relate to gut function. Sixteen pigs were subjected to sodium butyrate (SB) supplementation via beverage water or water only [control (C)]. All pigs had blood sampled after 2 and 3 wk of treatment, and were subjected to a brain positron emission tomography after 3 wk. Animals were euthanized after 4 wk to sample pancreas, intestine, and brain for gut physiology and anatomy measurements, as well as hippocampal histology, Ki67, and doublecortin (DCX) immunohistochemistry...

OBJECTIVE: Current clinical practice of assessing neonatal condition is based on evaluation of umbilical cord arterial blood pH value rather than lactate. However, evidence shows that lactate is direct and more predictive measurement than pH or at least of equal importance. This study is to assess and compare umbilical cord arterial lactate and pH values for predicting short-term neonatal outcomes. MATERIALS AND METHODS: A retrospective cohort study was conducted at the tertiary level hospital, were arterial umbilical cord blood sampling was collected according to the standard procedures...

BACKGROUND/AIMS: Stroke is the leading cause of adult disability, and glutamate-induced dysregulation of intracellular Ca2+ homeostasis is a key mechanism. FAM3A is the first member of the family with sequence similarity 3 (FAM3) gene family, and its biological function remains largely unknown. We have recently reported that FAM3A exerts protective effects against oxidative stress and mitochondrial dysfunction in HT22 cells. METHODS: Here, we investigated the protective effects of FAM3A using a glutamate-induced neuronal injury model in nerve growth factor (NGF)-differentiated PC12 cells...

BACKGROUND/AIMS: Troxerutin, also known as vitamin P4, has been commonly used in the treatment of chronic venous insufficiency (CVI) disease. However, its effect on in vivo myocardial ischemia/reperfusion (I/R) injury, a model that closely mimics acute myocardial infarction in humans, is still unknown. METHODS: The myocardial I/R injury rat model was created with troxerutin preconditioning. Myocardial infarct size was evaluated by the Evans blue-TTC method. Hemodynamic parameters, including the heart rate (HR), left ventricular end-diastolic pressure (LVEDP), left ventricular systolic pressure (LVSP), maximal rate of rise in blood pressure in the ventricular chamber (+dp/dt max), and maximal rate of decline in blood pressure in the ventricular chamber (-dp/dt max) were monitored...

Temporary mechanical circulatory support (TCS) is recommended for patients with profound cardiogenic shock (CS). Extracorporeal membrane oxygenation (ECMO) and Impella are possible TCS devices, but the device choice and the implantation timing are not definitely established, specifically during acute myocardial infarction. We have analyzed the respective use of ECMO or Impella (2.5, CP, or 5.0) for CS following acute myocardial infarction , from a cohort of patients who underwent TCS within 72 hours after admission for emergency percutaneous coronary intervention (PCI) from January 2009 to April 2015...

Introduction Maternal obesity is associated with an increased risk for adverse perinatal outcomes. Obesity is also associated with a chronic inflammatory state and metabolic derangements that affect the newborn. The additional use of cardiopulmonary bypass during the neonatal period could impact the systemic inflammatory response in the immediate postoperative period that manifests as cardiac depression and multi-organ dysfunction. This study aimed to determine the association of maternal obesity and excessive weight gain during pregnancy with the immediate postoperative morbidity of neonatal patients undergoing cardiopulmonary bypass...

Seipin is an integral endoplasmic reticulum (ER) membrane protein encoded by Berardinelli-Seip congenital lipodystrophy type 2 (BSCL2/Bscl2) gene. Most litters (59%) from Bscl2-/- dams mated with WT (Bscl2+/+) males didn't survive PND5 and pups (Bscl2+/-) lacked milk in their stomachs. The survived litters had reduced pup survival rate at PND21. It was hypothesized that seipin was critical for lactation. Bscl2 was upregulated and highly detected in the lactation day 1 (LD1) WT mammary gland alveolar epithelial cells...
