Caspase activation has been shown to be a critical step in several models of neuronal apoptosis such as staurosporine treatment of human neuroblastoma SH-SY5Y cells and potassium deprivation of rat cerebellar granule neurons. One common event is the appearance of caspase-mediated 120-kDa
We describe a case of non-islet cell tumour hypoglycaemia (NICTH) associated with a renal cell carcinoma. Serum insulin-like growth factors (IGFs) (including IGF-II E peptide), IGF-binding proteins (IGFBPs), insulin and C-peptide were measured before and after surgical removal of the tumour. IGFBPs
Hypoglycemia impairs blood-brain barrier (BBB) endothelial function; a major hallmark in the pathogenesis of various CNS disorders. Previously, we have demonstrated that prolonged hypoglycemic exposure down-regulated BBB endothelial NF-E2 related factor-2 (Nrf2) expression; a redox-sensitive
Blockade of mitochondrial permeability transition protects against hypoglycemic brain damage. To study the mechanisms downstream from mitochondria that may cause neuronal death, we investigated the effects of cyclosporin A on subcellular localization of apoptosis-inducing factor and cytochrome c,
A 75-year-old man was admitted to our hospital because of unconsciousness. His plasma glucose was very low, but his serum levels of insulin and IGF-I were also low. He was found to have a giant solitary pleural tumor, which was completely resected, after which his hypoglycemia ameliorated
We have previously described a case of tumor-associated hypoglycemia secondary to the production of high molecular weight insulin-line growth factor (IGF)-II in a child with congenital neuroblastoma. The child's hypoglycemia resolved with GH therapy and has continued to be well controlled for 1 yr.
Deposition of beta-amyloid (A beta) is a characteristic feature of the pathology of Alzheimer's disease (AD). Since glucose metabolism and the consequential ATP production are depressed in the temporal and parietal regions of the cortex in patients with AD, we designed the present study to
The aim of the present work was to investigate the effectiveness of a dosage form approach for monitoring both the inactivation and the absorption process by targeting insulin delivery to the upper region of small intestine. The dosage form is based on the incorporation of insulin with protease
OBJECTIVE
We hypothesized that HIV-positive women on protease inhibitors (PIs) would be more likely to have an elevated glucola test result than those not on PIs.
METHODS
We reviewed our database of all HIV-positive pregnant women seen at our hospital. Serum glucose was measured 1 hour following a
Repeated severe insulin-induced hypoglycemia in rats has led to an increase in aminotransferase, glutaminase, and glutamate dehydrogenase activities in the liver; protease activities in tissues; and in blood serum levels of free fatty acids, urea, and uric acid. These changes are indicative of
OBJECTIVE
Non-islet cell tumour induced hypoglycaemia (NICTH) is a paraneoplastic phenomenon that is associated with the formation of several isoforms of pro-insulin like growth factor 2 (pro-IGF-II), or so called "big" IGF-II. Disturbance of ternary complex formation by big IGF-II is assumed to be
Microorganisms from extreme and restrictive eco systems, such as the Antarctic continent, are of great interest due to their ability to synthesize products of commercial value. Among these, enzymes from psychrotolerant and psychrophilic microorganisms offer potential economical benefits due to their
Reports that Clostridium botulinum toxin can sometimes be detected in the absence of indicators of overt spoilage led to a systematic study of this phenomenon in a model system. Media with various combinations of pH (5.0 to 7.0) and glucose (0.0 to 1.0%) were inoculated with vegetative cells of C.
Solid tumors usually have regions of hypoxia and glucose deprivation. Human colon carcinoma HT-29 cells show an apoptosis-resistant phenotype in response to microenvironmental stresses. In this study, we isolated a novel mutant of HT-29, designated as HA511, that showed a high apoptotic response to
Serine protease dipeptidyl peptidase 4 (DPP-4) is involved in self/non-self-recognition and insulin sensitivity. DPP-4 inhibitors are conventional choices for diabetic treatment; however, side effects such as headache, bronchus infection, and nasopharyngitis might affect the daily lives of diabetic
