The activity of glucokinase, hexokinase and glucose-6- phosphoric dehydrogenase of the liver and myocardium of rabbits was tested at different stages of pyrogenal fever with the aid of spectrophotometry. A marked decrease in the activity of the enzymes under study was observed in fever. After the
Activity of hexokinase and acetylcholinesterase and pyridoxal co-enzyme content of brain subcellular fractions were studied in rats, bearing sarcoma 45, after local exposure of the tumor to 20 Gy X-radiation and microwave hyperthermia. The carbohydrate metabolism was sharply inhibited while the
In marine ectotherms, reproduction is an energetically expensive process that affects their thermal window tolerance. For most species, the impacts of hyperthermia during gametogenesis have still not been addressed. Our aim was to assess the metabolic response of adult Nodipecten subnodosus scallops
Due to the substantial photosynthetic biomass in their habitat, salmonids such as the rainbow trout (Oncorhynchus mykiss) can be subject to hyperoxia in addition to high temperatures associated with climate change. Both stressful conditions increase the incidence of damaging reactive oxygen species
A 67 years old woman with a Waldenström disease was admitted in the intensive care unit for dyspnea and fever. During hospitalization, episodes of undetectable glycemia were observed without any hypoglycemia symptoms. Plasma glucose was determined with the hexokinase method (recommended). From this
The effects of temperature on the relationships among the rates of pyruvate carboxylation, O(2) uptake (J(o)), oxidative phosphorylation (J(p)), and the free energy of ATP hydrolysis (G(p)) were studied in liver mitochondria isolated from 250-g female rats. Pyruvate carboxylation was evaluated at
Malignant gliomas have been associated with a high rate of glycolytic activity which is believed necessary to sustain cellular function and integrity. Since lonidamine (LND) is believed to reduce tumor glucose utilization by inhibition of the mitochondrially-bound glycolytic enzyme hexokinase (HK),
Thirteen patients, including 6 from one family, with the syndrome of myoclonus epilepsy and ragged-red fibres (MERRF) were studied. There was considerable heterogeneity in the age of onset, severity and associated clinical features. Postmortem studies in 3 patients from the one family showed a
The experimental and theoretical bases for the use of Lonidamine in cancer therapy are reviewed and discussed. In murine tumors Lonidamine has a narrow spectrum of antitumor effects. It lacks the characteristic properties of antiproliferative drugs, as well as other important pharmacological
The mosquito Aedes aegypti is vector of several viruses including yellow fever virus, dengue virus chikungunya virus and Zika virus. One of the major problems involving these diseases transmission is that A. aegypti embryos are resistant to desiccation at the end of embryogenesis, surviving and
BACKGROUND
Aegle marmelos (L.) Corr. (Rutaceae), commonly known as bael, is used to treat fevers, abdomen pain, palpitation of the heart, urinary troubles, melancholia, anorexia, dyspepsia, diabetes and diarrhea in Indian traditional systems of medicine. The object of the present study was to
1- Oncogenes express proteins of "Tyrosine kinase receptor pathways", a receptor family including insulin or IGF-Growth Hormone receptors. Other oncogenes alter the PP2A phosphatase brake over these kinases. 2- Experiments on pancreatectomized animals; treated with pure insulin or total pancreatic
