Muscle Function Differences between Patients with Bulbar and Spinal Onset Amyotrophic Lateral Sclerosis. Does It Depend on Peripheral Glucose?
2021
Background: One of the pathogenic mechanisms of ALS disease is perturbed energy metabolism particularly glucose metabolism. Given the substantial difference in the severity and the prognosis of the disease, depending on whether it has a bulbar or spinal onset, the aim of the study was to determine metabolic differences between both types of ALS, as well as the possible relationship with muscle function. Materials and Methods: A descriptive, analytical, quantitative, and transversal study was carried out in hospitals and Primary Care centers in the region of Valencia, Spain. Fasting glucose and alkaline phosphatase (AP) levels in venous blood, muscle percentage, fat percentage, muscle streng…
Dietary polyphenols as antidiabetic agents: Advances and opportunities
2020
Abstract Dietary polyphenols have been widely investigated as antidiabetic agents in cell, animals, human study, and clinical trial. The number of publication (Indexed by Web of Science) on “polyphenols and diabetes” significantly increased since 2010. This review highlights the advances and opportunities of dietary polyphenols as antidiabetic agents. Dietary polyphenols prevent and manage Type 2 diabetes mellitus via the insulin‐dependent approaches, for instance, protection of pancreatic islet β‐cell, reduction of β‐cell apoptosis, promotion of β‐cell proliferation, attenuation of oxidative stress, activation of insulin signaling, and stimulation of pancreas to secrete insulin, as well as…
A simple strategy based on photobiotin irradiation for the photoelectrochemical immobilization of proteins on electrode surfaces
2006
Abstract A photoactivable organic polymer was prepared first by electrogeneration of a conductive biotinylated polypyrrole film in acetonitrile electrolyte. The successive anchoring of avidin and photobiotin led to a multilayer configuration. The latter was illuminated with light (wavelength 370–400 nm) in the presence of proteins adsorbed onto its surface. The irradiation allowed the covalent linking of the proteins to the modified electrode. As a result of the photochemical reaction, a monolayer of enzyme (glucose oxidase, GOX or alkaline phosphatase, AP) was covalently bound to the photobiotin-modified surface with retention of their catalytic activities. The surfacic activities were 34 …
Electrochemical biosensors for glucose based on metal nanoparticles
2013
Abstract Nanotechnology has affected almost all aspects of biomedicine. The integration of nanomaterials has contributed to the selectivity, the versatility, the stability and especially the sensitivity of bioelectronic devices, including biosensors. In this field, nanomaterials have been employed as enzyme immobilizers, enzyme stabilizers, surface modifiers or labeling factors or have provided individualized catalytic effects. Among other sensing platforms, glucose biosensors are of special clinical and industrial significance because of their role in monitoring blood-glucose levels in diabetes mellitus, one of the most prevalent metabolic disorders worldwide. Similar to other sensing plat…
Glucose uptake in germinating Aspergillus nidulans conidia: involvement of the creA and sorA genes
2003
d-Glucose uptake in germinating wild-typeAspergillus nidulansconidia is an energy-requiring process mediated by at least two transport systems of differing affinities for glucose: a low-affinity system (Km∼1·4 mM) and a high-affinity system (Km∼16 μM). The low-affinity system is inducible by glucose; the high-affinity system is subject to glucose repression effected by the carbon catabolite repressor CreA and is absent insorA3mutant conidia, which exhibit resistance tol-sorbose toxicity. An intermediate-affinity system (Km∼400 μM) is present insorA3conidia germinating in derepressing conditions.creAderepressed mutants show enhanced sensitivity tol-sorbose. The high-affinity uptake system ap…
Effect of short-term guided aerobic exercise and diet intervention on overweight women
2010
Abstract Effect of Short-Term Guided Aerobic Exercise and Diet Intervention on Overweight Women Kauko, Kirsi LLTS007 Master’s Thesis of Sport Medicine University of Jyväskylä, Faculty of Sport and Health Sciences, Department of Health Sciences Spring 2010, 68 pages, 6 appendices Overweight or obese persons have substantially increased risk for multiple chronic disorders, for example type 2 diabetes (T2D), dyslipidemia, hypertension and cardiovascular disease (CVD). Physical activity or exercise has an important role in the prevention and treatment of obesity related illnesses, for example T2D, CVD and metabolic syndrome (MetS). The main goal of this Master’s thesis is to study the possible …
Empagliflozin Induces White Adipocyte Browning and Modulates Mitochondrial Dynamics in KK Cg-Ay/J Mice and Mouse Adipocytes
2021
Background: White adipose tissue (WAT) browning is a promising target for obesity prevention and treatment. Empagliflozin has emerged as an agent with weight-loss potential in clinical and in vivo studies, but the mechanisms underlying its effect are not fully understood. Here, we investigated whether empagliflozin could induce WAT browning and mitochondrial alterations in KK Cg-Ay/J (KKAy) mice, and explored the mechanisms of its effects.Methods: Eight-week-old male KKAy mice were administered empagliflozin or saline for 8 weeks and compared with control C57BL/6J mice. Mature 3T3-L1 adipocytes were treated in the presence or absence of empagliflozin. Mitochondrial biosynthesis, dynamics, a…
In response to the paper 'High-protein diet: A barrier to the nephroprotective effects of sodium-glucose co-transporter-2 inhibitors?'
2020
We agree with the paper recently published in your journal regarding the relationship between a high‐protein diet and the possible neutral effect of sodium‐glucose co‐transporter‐2 inhibitors (SGLT2inh),1 but wish to discuss certain nuances.
Enzym-histochemische Studien am cervicalen Dr�senfeld des Uterus
1972
Durch enzym-histochemische Untersuchungen an Cervices soll Einblick in den Stoffwechsel des cervicalen Drusenfeldes gewonnen werden. Hierfur wurden insbesondere die Enzyme des Glucosestoffwechsels, der Fettsaureoxydation, des Pentosephosphatstoffwechsels, des Citronensaurecyclus sowie des NADH- und NADPH-Diaphorese-Systems und des Aminosaurestoffwechsels untersucht. Die einheitliche Nachweistechnik erlaubt in Form eines Art Screening-Tests eine Information uber die vorhandenen Aktivitaten der einzelnen Enzyme, wobei — abgesehen von einem Enzym des Glucosestoffwechsels, namlich der Alkoholdehydrogenase und des Aminosaurestoffwechsels, der Glutamatdehydrogenase — alle Fermente nachgewiesen we…
