BREATH ACETONE-BASED NON-INVASIVE DETECTION OF BLOOD GLUCOSE LEVELS

There has been a constant demand for the development of non-invasive, sensitive glucose sensor system that offers fast and real-time electronic readout of blood glucose levels. In this article, we propose a new system for detecting blood glucose levels by estimating the concentration of acetone in the exhaled breath. A TGS822 tin oxide (SnO2) sensor has been used to detect the concentration of acetone in the exhaled air. Acetone in exhaled breath showed a correlation with the blood glucose

Then, the use of an adequate mathematical model describing the joint effect of the culture pH and nutrient (glucose) addition on the productions of biomass, nisin and fermentation products could provide a better understanding for controlling and optimizing the fermentation process. However, to our knowledge, no information is available on the quantification of the joint effect of glucose addition with the feeding media and the pH gradients (VpH) generated in the cultures on the synthesis of

Genes Controlling 2-deoxyglucose Induced Lysis and Formation of Reactive Oxygen Species in Schizosaccharomyces pombe

Schizosaccharomyces pombe cells of strains each carrying a deletion of one of the genes snf5, ypa1, pho7 and pas1 and of a strain overexpress­ing gene odr1, have been previously shown to grow in presence of the toxic glucose analogue 2-deoxyglucose (2-DG). Here we report that these genes control 2-DG induced lysis and are, with the exception of odr1, also involved in control of formation of reactive oxygen species (ROS) upon exposure of cells to H2O2. Lysis of deletion strains, but not of

Glucose transporter type 1 deficiency syndrome (GLUT1-DS) – delayed diagnosis and treatment. A case report

BACKGROUND Glucose is the major carbon and energy source of nerve cells, supporting brain growth and neural excitation. The glucose transporter of capillary endothelial cells located at the blood brain barrier (BBB), facilitates the passive flux of glucose from blood to brain (Wong et al., 2007) and is also responsible for astrocyte glucose transport. Glucose membrane transporters (GLUT) proteins are encoded by the SLC2 genes. They are members of the major facilitator super family (MFS) which

The interplays between blood sugar, antioxidant defense and trace elements have been investigated in previous studies. High blood glucose levels have been shown to increase antioxidants in endothelial cells, reflecting the importance of antioxidant defense in neutralizing the toxic effect of high glucose (Ceriello et al., 1996). In contrast, the high blood glucose levels observed in diabetes mellitus

Hindbrain metabolic deficiency regulates ventromedial hypothalamic nucleus glycogen metabolism and glucose-regulatory signaling

INTRODUCTION The ventromedial hypothalamic nucleus (VMN) utilizes metabolic sensory information in the form of nutrient, endocrine, and neurochemical cues to direct glucose counter-regulatory motor functions (Watts and Donovan, 2010; 2014). Specialized energy substrate-sensitive neurons in the VMN provide a dynamic cellular energy readout by augmenting (‘fuel-inhibited’) or decreasing (‘fuel-excited’) synaptic firing as oxidizable fuel levels dwindle (Oomura et al., 1969; Silver and Erecinska

PREDIABETES AND THE NEED FOR CARDIOVASCULAR RISK ASSESSMENT IN AVIATION

ABSTRACT Obesity, the disease of the twenty-first century, has a range of serious consequences to health. These are related in part to abnormal glucose levels, resulting in inflammatory and atherogenic response, hypertension and abnormal lipid profile. This increases the risk of cardiovascular disease significantly besides developing diabetes later. Hyperglycaemia is diagnosed with impaired fasting glucose and/or impaired glucose tolerance or elevated glycated haemoglobin (HbA1c). The Royal

The isolate is able to ferment glucose, fructose and sucrose with biohydrogen production rate and yield of 0.8 mol/l/h and 3.8 mol/g, respectively at 10 g/l glucose concentration. It also showed 74% carbohydrate uptake and 95% oxygen uptake ability, and a wide growth temperature range with optimum at 37°C. Klebsiella sp.

Abstract The aim of the study was mycological examination of ulcerated corneal tissues from an ophthalmic patient. Tissue fragments were analyzed on potato-glucose agar (PDA) and maltose (MA) (Difco) media using standard laboratory techniques. Cultures were identified using classical and molecular methods. Macro- and microscopic colony morphology was characteristic of fungi from the genus Aspergillus (restricted growth series), most probably Aspergillus penicillioides Speg. Molecular analysis

FRUCTOPHILIC LACTIC ACID BACTERIA (FLAB) – A NEW GROUP OF HETEROFERMENTATIVE MICROORGANISMS FROM THE PLANT ENVIRONMENT

Recently, a unique kind of lactic acid bacteria (LAB) i.e. fructophilic lactic acid bacteria (FLAB), has been described. This specific group prefers D-fructose over D-glucose as a carbon source to growth. They can be found in fructose rich environments such as flowers, fruits and food products made of fermented fruits, for example tempoyak. In recent years, it has been revealed that insects which feed on food high in fructose are an abundant source of fructophilic bacteria. Bacterial

. After deglycerolization, RBCs were preserved with either SAG-M or AS3 and stored for at least 10 or 14 days, respectively. Quality of stored RBCs was assessed by measuring osmolarity, blood cell counts, free hemoglobin, adenosine triphosphate (ATP), hemolysis, and glucose. The overall RBC mass recovery after deglycerolization was 86 ± 7.6 percent, and the osmolarity was 336 ± 23 mOsml/kg H2O. The hemolysis for stored components at the end of their shelf life was 0.21 ± 0.08

The presence of Alicyclobacillus, a thermoacidophilic and spore-forming bacterium, in acidic fruit juices poses a serious problem for the processing industry. A typical sign of spoilage in contaminated juices is a characteristic phenolic off-flavour associated with the produc­tion of guaiacol. Spores are formed in response to starvation and in a natural environment re-access the nutrients, e.g.: L-alanine and AGFK – a mixture of asparagine, glucose, fructose and potassium, triggers

Among S. aureus virulence factors, superantigens (SAgs) are essential for pathogenicity. The long-term effect of the superantigen toxic shock syndrome toxin-1 (TSST-1) might be glucose intolerance. This toxin also induces systemic inflammation as a result of the increased exotoxin concentration in blood, and, therefore, may be the causative factor of diabetes. Chronic exposure to
