The main objectives of this study were threefold: (1) To determine whether acute ingestion of K me ; (R)-3-hydroxybutyl (R)-3-hydroxybutyrate impacts plasma glucose levels during a standardized oral glucose tolerance test (OGTT). (2) To compare changes in insulin concentrations and estimates of insulin sensitivity after acute K me supplementation. Twenty healthy participants (n = 10 males/females) aged between 18-35 years took part in a randomized crossover study. After an overnight fast, participants consumed a K me supplement (ΔG®; 0...

Two experiments were conducted to determine relationships of blood metabolite concentrations, BW, BCS, and rump fat depth with postpartum ovulation and pregnancy risks, as well as their utility in predicting those outcomes in suckled beef cows. In Exp. 1, plasma glucose collected 10 and 3 d before AI of suckled beef cows at 7 locations did not differ between cows that had resumed estrous cycles (ovulated) before AI compared with anovulatory cows, whereas plasma glucose 3 d before AI was greater (P < 0.01) in cows that became pregnant compared with nonpregnant cows...

The review describes the technologies used in the field of breath analysis to diagnose and monitor diabetes mellitus. Currently the diagnosis and monitoring of blood glucose and ketone bodies that are used in clinical studies involve the use of blood tests. This method entails pricking fingers for a drop of blood and placing a drop on a sensitive area of a strip which is pre-inserted into an electronic reading instrument. Furthermore, it is painful, invasive and expensive, and can be unsafe if proper handling is not undertaken...

The high energy demands of the substantia nigra pars compacta dopaminergic (DASNc) neurons render these neurons vulnerable to degeneration. These energy demands are a function of their long and extensively arborized axons and very large number of transmitter release sites, and are further augmented by their natural pacemaking activity. Pacemaking is driven by the rhythmic entry of Ca2+ into the cell and, while the entry of Ca2+ into the neuron stimulates energy (ATP) production, the extrusion of Ca2+ conversely saps the energy that is generated...

REVIEW
Timothy A Simeone, Kristina A Simeone, Carl E Stafstrom, Jong M Rho
Although the mechanisms underlying the anti-seizure effects of the high-fat ketogenic diet (KD) remain unclear, a long-standing question has been whether ketone bodies (i.e., beta-hydroxybutyrate [BHB], acetoacetate [ACA] and acetone), either alone or in combination, contribute mechanistically. The traditional belief has been that while ketone bodies reflect enhanced fatty acid oxidation and a general shift toward intermediary metabolism, they are not likely to be the key mediators of the KD's clinical effects, as blood levels of BHB do not correlate consistently with improved seizure control...

Hemorrhagic shock is the leading cause of preventable death after trauma. Hibernation-based treatment approaches have been of increasing interest for various biomedical applications. Due to apparent similarities in tissue perfusion and metabolic activity between severe blood loss and the hibernating state, hibernation-based approaches have also emerged for the treatment of hemorrhagic shock. Research has shown that hibernators are protected from shock-induced injury and inflammation. Utilizing the adaptive mechanisms that prevent injury in these animals may help alleviate the detrimental effects of hemorrhagic shock in non-hibernating species...

Assays for the rapid detection and accurate differentiation of Burkholderia pseudomallei from near-neighbor species are urgently needed in melioidosis endemic regions due to the high associated mortality and biowarfare importance of the pathogen. PCR-based methods have revolutionized this field due to the accuracy, sensitivity, and specificity that are achievable in a rapid way. In this study, a compound molecular detection system, consisting of a duplex PCR assay, was developed for the specific identification of Burkholderia pseudomallei and differentiation from other Burkholderia species...

The periparturient period of dairy cows is characterized by intense lipolysis in adipose tissues (AT), which induces the release of free fatty acids (FFA) into circulation. Among FFA, polyunsaturated fatty acids are susceptible to oxidation and can modulate inflammatory responses during lipolysis within AT. Linoleic and arachidonic acid oxidized products (oxylipids) such as hydroxy-octadecadienoic acids (HODE) and hydroxy-eicosatetraenoic acids (HETE), were recently identified as products of lipolysis that could modulate AT inflammation during lipolysis...

BACKGROUND: In Japan, Meiji 817-B (M817-B), a powdered ketogenic milk, has been available since the ketogenic diet was introduced to infants and tube-fed children with medication-resistant epilepsy in the 1980s. METHODS: We retrospectively evaluated the efficacy, tolerability, and side effects of the ketogenic diet using M817-B as the main source of daily food intake for patients with epilepsy by sending questionnaires to the members of a subcommittee of the Japan Epilepsy Society that focuses on the proper use of M817-B...

Supplementation of dairy cows with trans-10, cis-12 conjugated linoleic acid (CLA) allows nutrient repartitioning despite an energy deficiency in early lactation, which might be a benefit for the immune system, too. In this study, we investigated potential nutrient sparing effects of CLA in early lactating cows with low plasma glucose concentrations exposed to an intramammary lipopolysaccharide (LPS) challenge. Fifteen multiparous Holstein cows were exposed to an intramammary LPS challenge in week 4 p.p. Eight cows (CLA) were supplemented daily with 70 g of lipid-encapsulated CLA (6...

OBJECTIVE: To determine the utility of capillary blood ketone levels as an indicator of inadequate intake of breast milk in the early postnatal period. STUDY DESIGN: Levels of capillary blood beta-hydroxybutyrate (βOHB), the main ketone body in the blood, were measured with a bedside ketone meter in 585 full-term neonates aged 48-95 hours who were breastfed exclusively. Relationships between weight-loss percentage, blood sodium, glucose, pH, partial pressure of carbon dioxide, base-deficit levels, and βOHB levels were investigated...

Ketosis is a very frequent metabolic disease in dairy cows, resulting in lower milk production, impaired fertility and increased frequency of other diseases. The course of the disease is often subclinical, so early detection is very important. The aim of the study was to investigate the relation between the concentration of beta-hydroxybutyrate in blood and milk and to determine the cut-off value in milk for detection of subclinical ketosis. The study included 94 cows, which were in the first third of lactation...

Sodium-glucose cotransporter 2 (SGLT2) inhibitors are used in the treatment of human diabetics. They increase glucose excretion and correct hyperglycemia. We examined the investigational SGLT2 inhibitor velagliflozin in two groups of six neutered adult obese cats (equal gender distribution). Placebo (Pl) or drug (D; 1 mg/kg) was administered for 35 days. Routine blood examinations, fructosamine, beta-hydroxybutyrate (BHB), nonesterified fatty acids (NEFA), glucagon, adiponectin, and leptin were measured before and after treatment, also water intake, and urinary electrolytes, glucose, and volume...

BACKGROUND: Low-carbohydrate diets have recently grown in popularity among endurance athletes, yet little is known about the long-term (>4 wk) performance implications of consuming a low-carbohydrate high fat ketogenic diet (LCKD) in well-trained athletes. METHODS: Twenty male endurance-trained athletes (age 33 ± 11y, body mass 80 ± 11kg; BMI 24.7 ± 3.1 kg/m2) who habitually consumed a carbohydrate-based diet, self-selected into a high-carbohydrate (HC) group (n = 11, %carbohydrate:protein:fat = 65:14:20), or a LCKD group (n = 9, 6:17:77)...

The present study aimed to investigate the perturbations in immuno-metabolic and redox status of buffaloes with trypanosomosis. Thirteen buffaloes suffering from clinical trypanosomosis and eight apparently healthy buffaloes were included in the present study. Buffaloes with trypanosomosis found to have markedly elevated levels of interleukin-10 (IL-10), nonesterified fatty acids (NEFA) and beta-hydroxybutyrate (BHBA) in comparison with healthy controls. Whereas, total antioxidant capacity (TAC) and haemoglobin levels of buffaloes with trypanosomosis were significantly lower than the healthy controls...

Supplementing conjugated linoleic acid (CLA) is supposed to spare glucose due to the milk fat-depressing effect of the trans-10, cis-12 CLA isomer, and allows repartitioning nutrients despite an energy deficiency in early lactation. However, there is still a lack of knowledge in terms of the dynamic pattern of the glucose turnover in transition dairy cows. We hypothesized that dairy cows supplemented with CLA have an altered rate of glucose turnover and insulin sensitivity during early lactation. We conducted three consecutive hyperglycaemic clamps (HGC) in weeks -2, +2 and +4 relative to parturition in Holstein cows supplemented daily either with 70 g of lipid-encapsulated CLA (6...

Seabird parents use a conservative breeding strategy that favours long-term survival over intensive parental investment, particularly under harsh conditions. Here, we examine whether variation in several physiological indicators reflects the balance between parental investment and survival in common murres (Uria aalge) under a wide range of foraging conditions. Blood samples were taken from adults during mid-chick rearing from 2007 to 2014 and analysed for corticosterone (CORT, stress hormone), beta-hydroxybutyrate (BUTY, lipid metabolism reflecting ongoing mass loss), and haematocrit (reflecting blood oxygen capacity)...
