Methylglyoxal (MG) is a reactive α-oxoaldehyde that increases under diabetic conditions and subsequently contributes to the complications associated with this disease. Piceatannol is a naturally occurring analogue of resveratrol that possesses multiple biological functions. The present study investigated the effects of piceatannol on MG-induced cytotoxicity in MC3T3-E1 osteoblastic cells. Piceatannol significantly restored MG-induced reductions in cell viability and reduced lactate dehydrogenase release in MG-treated MC3T3-E1 osteoblastic cells, which suggests that it suppressed MG-induced cytotoxicity...

INTRODUCTION: Lactate concentration in umbilical cord blood is an important measure of intrapartum anaerobic metabolism. The aim of the study was to compare lactate production of large-for-gestational-age (LGA) fetuses against appropriate-for-gestational-age (AGA) fetuses during hypoxia, in diabetic and non-diabetic mothers. MATERIAL AND METHODS: 17 358 validated paired arterial and venous umbilical cord blood samples taken at birth with a full panel of pH, glucose and lactate were analyzed relative to LGA (n=2789) and AGA (n=14 569)...

Novel and alternative options are being adopted to combat the initiation and progression of human cancers. One of the approaches is the use of molecules isolated from traditional medicinal herbs, edible dietary plants and seeds that play a pivotal role in the prevention/treatment of cancer, either alone or in combination with existing chemotherapeutic agents. Compounds that modulate these oncogenic processes are potential candidates for cancer therapy and may eventually make it to clinical applications. Diosgenin is a naturally occurring steroidal sapogenin and is one of the major bioactive compounds found in dietary fenugreek ( Trigonella foenum-graecum ) seeds...

We have retrospectively examined a wide range of clinical characteristics, sonographic features, microbiology, and antibiotic regimens in patients with breast abscesses to seek predictive features related to outcome. Because consensus for optimal treatment of breast abscesses has moved toward minimally invasive management using single or repeated needle aspiration (ASP) coupled with adjuvant antibiotics, we assessed whether any factors correlate with the need for repeat procedures by analyzing the number of ASPs and/or surgical incision and drainage (I&D) per abscess...

BACKGROUND: Acute kidney injury (AKI) is a common complication in septic patients, imposing a heavy burden of illness in terms of morbidity and mortality. Serum lactate is a widely used marker predicting the severity of sepsis. A paucity of research has investigated septic AKI in emergency departments (EDs) and its correlation with initial serum lactate level. This study aimed at identifying risk factors for septic AKI and clarifying the link between initial serum lactate level and septic AKI in ED patients...

AIMS AND OBJECTIVES: If the knowledge and health beliefs relating to gestational diabetes mellitus (GDM) during pregnancy are associated with behaviours during pregnancy and lactation, this suggests potential educational interventions. BACKGROUNDS: Women with GDM are more likely to develop type 2 diabetes mellitus (T2DM), and babies with GDM incur increased risk of neonatal hypoglycaemia and childhood obesity. Breastfeeding is an effective way to improve maternal and lipid metabolism of gestational diabetes mothers, and to lower the risk of T2DM after birth, to prevent conception...

Obesity affects male fertility and maternal diabetes affects the offspring sperm epigenome. However, the effects of in utero exposure to maternal glucose intolerance in combination with postnatal high fat, high sucrose (HFHS) diet consumption on offspring spermatogenesis is not clear. The present study was designed to test these effects. One week before and during pregnancy, dams were fed either control or HFHS diet to induce gestational glucose intolerance, and returned to standard diet during lactation. Male offspring from each maternal group were split into control and HFHS-fed groups for eight weeks prior to sacrifice at 11, 19 or 31 weeks of age, and reproductive tissues were harvested for analysis of testicular germ cell apoptosis and sperm output...

Brain tissue is bioenergetically expensive. In humans, it composes approximately 2% of body weight and accounts for approximately 20% of calorie consumption. The brain consumes energy mostly for ion and neurotransmitter transport, a process that occurs primarily in synapses. Therefore, synapses are expensive for any living creature who has brain. In many brain diseases, synapses are damaged earlier than neurons start dying. Synapses may be considered as vulnerable sites on a neuron. Ischemic stroke, an acute disturbance of blood flow in the brain, is an example of a metabolic disease that affects synapses...

The mortality rate of post-infarction cardiogenic shock (CS) was 80.0-90.0%. Recent studies show a significant reduction of hospital mortality to approximately 50.0%. CS is defined as systemic tissue hypoperfusion resulting from systolic and/or diastolic heart dysfunction, the main cause of which is acute myocardial infarction (AMI). The main predictors are biological markers such as troponin, CKMB and lactate. A systematic literature review and meta-analysis is performed in order to present and correlate the main literary findings on CS and its evolution with possible changes in biomarkers such as troponin, lactate and CKMB...

Administration of lactate during hypoglycemia suppresses symptoms and counterregulatory responses, as seen in patients with type 1 diabetes and impaired awareness of hypoglycemia (IAH), presumably because lactate can substitute for glucose as a brain fuel. Here, we examined whether lactate administration, in a dose sufficient to impair awareness of hypoglycemia, affects brain lactate levels in patients with normal awareness of hypoglycemia (NAH). Patients with NAH ( n = 6) underwent two euglycemic-hypoglycemic clamps (2...

Diabetes is a common chronic condition in women of reproductive age. Preconception care is crucial to reducing the risk of adverse maternal and fetal outcomes, such as hypertensive disorders, abnormal fetal growth, traumatic delivery and stillbirth, associated with poor glycemic control. Insulin is the preferred medication to optimize glucose control in women with pregestational diabetes. Frequent dose adjustments are needed during pregnancy to achieve glycemic goals, and team-based multidisciplinary care may help...

The pyruvate dehydrogenase complex (PDC) is a key control point of energy metabolism and is subject to regulation by multiple mechanisms, including post-translational phosphorylation by pyruvate dehydrogenase kinase (PDK). Pharmacological modulation of PDC activity could provide a new treatment for diabetic cardiomyopathy, as dysregulated substrate selection is concomitant with decreased heart function. Dichloroacetate (DCA), a classic PDK inhibitor, has been used to treat diabetic cardiomyopathy, but the lack of specificity and side effects of DCA indicate a more specific inhibitor of PDK is needed...

Visceral adipose tissue-derived serine protease inhibitor (Vaspin) is an adipocytokine that has been shown to exert anti-inflammatory effects and inhibits apoptosis under diabetic conditions. This study was designed to investigate the impact of vaspin on autophagy in tumor necrosis factor (TNF)-α-induced injury in cardiomyocytes and its cardioprotective effects in the pathogenesis of diabetic cardiomyopathy (DCM). H9C2 cells were treated with TNF-α with or without vaspin in vitro. Tumor necrosis factor-α treatment inhibited autophagy and promoted apoptosis in H9C2 cells after stimulating for 24 hours...

BACKGROUND/AIMS: Pterostilbene (PT) exerts antidiabetic effects by decreasing blood glucose and modulating lipid metabolism and has been shown to attenuate myocardial ischemia-reperfusion (IR) injury in non-diabetic subjects. However, whether PT can protect against myocardial IR injury in diabetes is unknown. AMPK stimulation is indispensable in offering cardioprotection against myocardial IR injury in diabetes by limiting cardiac apoptosis. Thus, we hypothesized that PT may confer protection against myocardial IR injury in diabetes via AMPK activation...

Carrier peptides, termed protein transduction domains (PTDs), serve as provide promising vehicles for intranasal delivery of macromolecular drugs. A mutant PTD derived from human translationally controlled tumor protein (TCTP-PTD 13, MIIFRALISHKK) was reported to provide enhanced intranasal delivery of insulin. In this study, we tested whether its efficiency could be further improved by replacing amino acids in TCTP-PTD 13 or changing the amino acids in the carrier peptides from the l- to the d-form. We assessed the pharmacokinetics of PTD-mediated transmucosal delivery of insulin in normal rats and the activity of insulin in alloxan-induced diabetic rats...
