AIMS The present study was undertaken to evaluate the effect of methanolic leaf extract of Gymnema sylvestre (MLGS) on glucose transport (GLUT) and insulin resistance in vitro. MATERIALS AND METHODS Peroxisome proliferator-activated receptor-gamma (PPAR-γ) and GLUT-4 expression were assessed in L6 myotubes for concluding the GLUT activity, and adiponectin and leptin expression was studied in ...

The uterine cervix is highly innervated by the sensory nerves containing neuropeptides which change during pregnancy and are regulated, in part, by estrogen. These neuropeptides act as transmitters both in the spinal cord and cervix. The present study was undertaken to determine the expression pattern of the neuropeptide pituitary adenylate cyclase activating peptide (PACAP) in the cervix and i...

BACKGROUND Detrusor overactivity (DO) secondary to partial bladder outlet obstruction (PBOO) is closely associated with alteration of ion channels. The objective of this study is to investigate the expression of the TWIK-related arachidonic acid-activated K(+) channel (TRAAK) in the L6-S1 spinal cord of DO rats after PBOO. METHODS Female Sprague-Dawley rats undergoing PBOO surgery were screen...

It was shown previously that an N-terminal fragment (nM60) that encompasses amino acid residues 1 to 563 of megalin could induce active Heymann nephritis (AHN) as efficiently as the native protein. For delineation of a minimal structure within this fragment that is sufficient to induce AHN, smaller protein fragments that encompass residues 1 to 236 (L6), 1 to 195 (L5), 1 to 156 (L4), and 1 to 1...

The cellular function of amylin is investigated in L6 myocytes, a rat skeletal muscle cell line. Both rat amylin and human amylin-amide acutely cause a dose-dependent increase in cyclic AMP formation in L6 myocytes. 100 nM amylin stimulates intracellular cyclic AMP concentrations 12-fold, whereas human amylin-amide at this concentration causes only a 2-fold increase. Up to 10 mM human amylin ha...

The L6 rust resistance gene from flax was cloned after tagging with the maize transposable element Activator. The gene is predicted to encode two products of 1294 and 705 amino acids that result from alternatively spliced transcripts. The longer product is similar to the products of two other plant disease resistance genes, the tobacco mosaic virus resistance gene N of tobacco and the bacterial...

INTRODUCTION The purpose of this study was to evaluate radiation dose reduction in coronary computerised tomography angiography (CCTA), using a commercially available iterative reconstruction (IR) algorithm as well as the behaviour of the image noise. METHODS A total cohort of 47 patients underwent CCTA examination on a 64-slice multi-detector CT. They were divided into four groups according ...

INTRODUCTION The authors propose a simple method for assessment of canine kidney size derived from the radiological technique described by Finco et al in 1971. MATERIALS AND METHODS In 26 healthy dogs ultrasonography was used to measure the length, height, and thickness of each kidney. These measurements were correlated with the lengths of the fifth and sixth lumbar vertebrae (L5 and L6), als...

BACKGROUND High density lipoprotein (HDL) was reported to decrease plasma glucose and promote insulin secretion in type 2 diabetes patients. This investigation was designed to determine the effects and mechanisms of HDL on glucose uptake in adipocytes and glycogen synthesis in muscle cells. METHODS AND RESULTS Actions of HDL on glucose uptake and GLUT4 translocation were assessed with 1-[(3)H...

Metastasis is a coordinated process that depends on the interaction of cancer cells with the tumor microenvironment. Members of the transmembrane-4 superfamily (TM4SF) of surface proteins have been implicated in the regulation of cancer cell metastasis, and the expression of several TM4SF members on tumor cells is inversely correlated with patient prognosis. The tumor-associated antigen L6 (TAL...
