Metabolic disorders are complex abnormalities involving impaired glucose and lipid metabolism, associated with complications such as kidney disease, cardiovascular foot ulcer, retinopathy, neuropathy [...]

Our laboratory has characterized androgen metabolism in an androgen-responsive prostate cancer cell line (LNCaP) and showed that these cells accumulated intracellular testosterone primarily as glucuronidated metabolites. Using a cell-free assay with testosterone as substrate, we showed that LNCaP had UDP-glucuronosyltransferase (UDPGT) activity. Because dietary factors, such as flavonoids in so...

About biological affecting of flavonoids on animal organisms is known less,thus we selected flavonoids, flavanones and flavones, and their glycosides, which wereexamined as potential inducers of cytochrome(s) P450 when administrated by gavages intoexperimental male rats. The study was focused on induction of CYP1A1, the majorcytochrome P450 involved in carcinogen activation. The data obtained d...

Fluorodeoxyglucose positron emission tomography (FDG-PET) imaging based 3D topographic brain glucose metabolism patterns from normal controls (NC) and individuals with dementia of Alzheimer’s type (DAT) are used to train a novel multi-scale ensemble classification model. This ensemble model outputs a FDG-PET DAT score (FPDS) between 0 and 1 denoting the probability of a subject to be clinically...

PURPOSE To evaluate 2-deoxy-2-[(18)F]fluoro-d-glucose positron emission tomography imaging ((18)FDG-PET) as a predictive, noninvasive, pharmacodynamic (PD) biomarker of response following administration of a small-molecule insulin-like growth factor-1 receptor and insulin receptor (IGF-1R/IR) inhibitor, OSI-906. EXPERIMENTAL DESIGN In vitro uptake studies of (3)H-2-deoxy glucose following OSI...

Substantial experimental evidence suggests that several flavonoid classes are involved in glucose metabolism, but few clinical or epidemiologic studies exist that provide supporting human evidence for this relationship. The objective of this study was to determine if habitual intakes of specific flavonoid classes are related to incidence of type 2 diabetes (T2D). We followed 2915 members of the...

Phosphodiesterase 10A (PDE10A) inhibitors have recently been proposed as a new therapy for schizophrenia. The aim of this study was to enhance our understanding of the role of PDE10A inhibitors and potentially identify a clinically useful mechanistic/functional biomarker by using 2-deoxyglucose (2-DG) autoradiography. PDE10A inhibitors papaverine (10 and 40 mg/kg), 6,7-dimethoxy-4-[(3R)-3-(2-qu...

BACKGROUND Corn silk contains proteins, vitamins, carbohydrates, Ca, K, Mg and Na salts, fixed and volatile oils, steroids such as sitosterol and stigmasterol, alkaloids, saponins, tannins, and flavonoids. Base on folk remedies, corn silk has been used as an oral antidiabetic agent in China for decades. However, the hypoglycemic activity of it has not yet been understood in terms of modern phar...

Introduction Nonalcoholic fatty liver disease (NAFLD) with type 2 diabetes mellitus (T2DM) is associated severe clinical outcomes. MicroRNA (miR)-210 has been reported to be related T2DM and lipid metabolism. This study aimed determine whether miR-210 can predict the effects of glimepiride linagliptin on NAFLD T2DM. Material methods A total 86 patients were randomly categorized into two groups ...

Positron emission tomography (PET) is an effective tool for noninvasive examination of the body and provides a range of functional information. PET imaging with [(18)F]fluoro-2-deoxy-d-glucose ([(18)F]FDG) has been used to image alterations in glucose metabolism in brain or cancer tissue in the field of clinical diagnosis but not in the field of toxicology. A single dose of N-methyl-d-aspartate...
