Ketoacidosis occurring during lactation has been described infrequently. The condition is incompletely understood, but it appears to be associated with a combination of increased metabolic demands during lactation, reduction in carbohydrate intake and acute illness. We present a case of a 27-year-old woman, 8 weeks post-partum, who was exclusively breastfeeding her child whilst following a low carbohydrate diet. She developed gastroenteritis and was unable to tolerate an oral diet for several days. She presented with severe metabolic acidosis on admission with a blood 3-hydroxybutyrate of 5...

The aim of this study was to analyze the acute responses of bradykinin, insulin, and glycemia to exercise performed above and below lactate threshold (LT) in individuals with type 2 diabetes mellitus (T2D). Eleven participants with a diagnosis of T2D randomly underwent three experimental sessions 72 h apart: 1) 20 min of exercise performed at 120% of LT (120%LT), 2) 20 min of exercise performed at 80% of LT (80%LT), and 3) 20 min of control session. Blood glucose was analyzed before, during, and at 45 min post-exercise...

REVIEW
Kelly J Gibas
Type II Diabetes affects 400 million people worldwide (IDF, 2013). The pathology is paradoxical: internal starvation activated by overfeeding. Hyperinsulinemic impairments of glucose homeostasis are treated with anti-hyperglycemics exacerbating cell starvation, inducing hypoglycemia and raising respiratory quotient. Reductions in hyperglycemia are achieved at the expense of glucose dependency and metabolic inflexibility (Gibas & Gibas, 2017). The brain is not immune from these cycles of starvation. The bioenergetic model characterizes propagation of late-onset, sporadic Alzheimer's disease as loss of molecular fidelity and compromised energy originating in brain networks with highest metabolic demand...

OBJECTIVES: Dioxins and PCBs are highly toxic and persistent environmental pollutants that are measurable in humans worldwide. These persistent organic pollutants are associated with a higher incidence of diabetes mellitus. We hypothesise that perinatal (background) exposure to industrial pollutants like dioxins also influences body mass development and energy metabolism in later life. STUDY DESIGN: In The Netherlands, the perinatal exposure (prenatal exposure and postnatal lactational intake) to dioxins has been studied prospectively since 1987...

AIM: We investigate how postweaning diet may modify the epigenetic landscape to meet metabolic demands later in life. METHODS: Sprague-Dawley rats were exposed to a high-fat (HF) diet during gestation and lactation. At weaning, male offspring were placed either on an HF diet (HF/HF) or a control diet (HF/C). Methylation-dependent immunoprecipitation sequencing and methylation-sensitive restriction enzyme sequencing were used to quantify hepatic DNA methylation. RESULTS: Out of the 3966 identified differentially methylated regions, 37% were mapped to gene bodies while 6% fell within promoter or downstream regions...

Metformin (MET) is prescribed for the treatment of type 2 diabetes mellitus and gestational diabetes. Although MET crosses the placenta, it is considered safe throughout gestation. However, it has been shown in humans that maternal exposure to MET increases sex hormone binding globulin levels in newborns, and in rats it decreases the testosterone concentration at gestational day (GD) 16.5. Therefore, the present study evaluated if maternal exposure to MET could interfere with reproductive parameters of male offspring...

Due to the difficulty of healing chronic wound, in the process of changing dressing, secondary damage on the tissue caused by adhesion should be prevented. In this study, the new dressing of particle hydrogels synthesized with poly-methyl methacrylate and poly-vinyl alcohol precursors were proposed. In addition, cell safety tests, animal's allergic stimulation, and animal's wound healing experiments were conducted for particle hydrogels. On one hand, in L929 cell experiment, the results of particle hydrogels extract 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide tests and lactate dehydrogenase test trial show that there are no safety concerns over particle hydrogels...

Metformin is widely used in the treatment of type 2 diabetes to lower blood glucose. Although metformin is a relatively safe and effective drug, its clinical efficacy is variable and under certain circumstances it may contribute to life-threatening lactic acidosis. Thus, additional understanding of metformin pharmacokinetics and pharmacodynamics could provide important information regarding therapeutic use of this widely prescribed drug. Here we report a significant effect of time of day on acute blood glucose reduction in response to metformin administration and on blood lactate levels in healthy mice...

Persistent hyperglycaemia coupled with inflammation plays an important role in the pathogenesis of diabetic nephropathy (DN). Present study examined the therapeutic potential of taraxerol isolated from the methanol extract of Abroma augusta leaf against DN using rodent model of type 2 diabetes (T2D). T2D was experimentally induced by high fat diet and a single low-single dose of streptozotocin (35mg/kg, i.p.). Accumulation of serum creatinine, urea, and uric acid, activation of lactate dehydrogenase and creatinin kinase, and release of urinary albumin represented the glomerular damage and the progression of nephropathy in T2D rats...

Feline mammary carcinoma (FMC) is a highly aggressive pathology that has been proposed as an interesting model of breast cancer disease, especially for the hormone refractory subgroup. Recently, cancer cell metabolism has been described as a hallmark of cancer cells. Here, we investigate the effects and mechanism of metabolic modulation by metformin (MET, anti-diabetic drug), 2-deoxyglucose (2DG, hexokinase inhibitor) or a combination of both drugs, MET/2DG on two established FMC cells lines: AlRB (HER2 (3+) and Ki67<5%) and AlRATN (HER2 (-) and Ki67>15%)...

The potential protective effect of epigallocatechin-3-gallate (EGCG) on type 2 diabetes-induced heart injury was investigated. A rat model of diabetes was achieved by injection of nicotinamide (100mg/kg, i.p), 20min before the administration of streptozotocin (55mg/kg, i.p.). After confirmation of diabetes, EGCG (2mg/kg, p.o.) was administrated on alternate days for one month. Treatment of diabetic rats with EGCG showed a remarkable reduction in glucose, glycosylated hemoglobin, HOMA-IR and lipid profile levels with an elevation in insulin levels, indicating its antihyperglycemic and antidyslipidemic actions...

Human diabetic patients may have increased lactate levels compared to non-diabetics. Despite the use of lactate levels in critical care assessment, information is lacking for diabetic dogs. Therefore, this prospective cross-sectional clinical study aimed to determine lactate concentrations in 75 diabetic dogs [25 newly diagnosed non-ketotic diabetics, 25 under insulin treatment, and 25 in diabetic ketoacidosis (DKA)], compared to 25 non-diabetic dogs. Lactate levels (mmol/L) were not different among groups (P = 0...

Folliculostellate cell gap junctions establish a network for the transmission of information within the anterior pituitary. Connexins make up gap junction channels. Changes in connexin (Cx) turnover modify gap junction-mediated intercellular communication. We have reported that cytokines and hormones influence Cx43 turnover and coupling in folliculostellate cells and in the folliculostellate cell line TtT/GF. In addition, the expression of different connexins alters intercellular communication and connexins may have functions besides cell coupling...

Metformin has been used for the treatment of some metabolic diseases during gestation and the beneficial effects of metformin to the vascular system have been described in diabetic and obese animal models. Nevertheless, the long term consequences to the vascular system of offspring maternally exposed to metformin have not yet been characterized. Therefore, we want to test the hypothesis that gestational and lactational exposure to metformin would be safe for the vascular reactivity of male adult offspring. Wistar female rats were treated with metformin 293mg/kg/day, by gavage, from gestational day (GD) 0 to GD 21 (METG) or GD 0 until post natal day (PND) 21 (METGL)...

Metformin (MET) is the first-line drug for treating type 2 diabetes mellitus (T2DM). However, MET increases blood lactate levels in patients with T2DM. Lactate possesses proinflammatory properties and causes insulin resistance (IR). Oxamate (OXA), a lactate dehydrogenase inhibitor, can decrease tissue lactate production and blood lactate levels. This study was conducted to examine the effects of the combination of OXA and MET on inflammation, and IR in diabetic db/db mice. Supplementation of OXA to MET led to lowered tissue lactate production and serum lactate levels compared to MET alone, accompanied with further decreased tissue and blood levels of pro-inflammatory cytokines, along with better insulin sensitivity, beta-cell mass, and glycemic control in diabetic db/db mice...
