Tumor necrosis factor-alpha (TNF alpha) is a multifunctional cytokine which exerts a myriad of biological actions in different tissues and species. Many of these actions can perturb the normal regulation of energy metabolism. In adipose tissue, in particular, TNF alpha has been demonstrated to regulate or interfere with adipocyte metabolism at numerous(More)
Tumor necrosis factor alpha (TNFalpha) is a potent cytokine with multiple biological activities and exists in two forms as follows: a 17-kDa soluble form that is a cleaved product of the 26-kDa transmembrane form (mTNFalpha). It has been suggested that the transmembrane form of TNFalpha is mainly responsible for localized responses via cell-cell contact.(More)
Tumour necrosis factor-alpha (TNFalpha) is a multifunctional cytokine that exerts a myriad of biological actions in numerous different tissues including adipocytes through its two distinct cell surface receptors. To address the role of each TNF receptor in the biological actions of TNFalpha in adipocytes, we have developed four new preadipocyte cell lines.(More)
BACKGROUND A student under optimal stress does bring out his or her best; however, extreme stress can result in mental health problems and deteriorates their academic performance. Students who esteem themselves low are most likely to engage in destructive and self-destructive behaviors. Moreover, excessive stress is harmful to academic performance and may(More)
UNLABELLED Circulating IL-6 levels are elevated in obesity. Although IL-6 is expressed in adipose tissue, neither its regulation nor cell of origin is well characterized. Here we investigated the beta-adrenergic regulation of IL-6 release in a combination of studies on humans and animals in vivo and cultured adipocytes in vitro. Human in vivo study: Human(More)
Efforts to establish human soft tissue and bone sarcomas in long-term cultures are described. Of 49 attempts 22 (45%) were successful, yielding cells that proliferated in vitro for 6 months or longer. Infrequent medium changes, maintenance of pH in physiologic range and avoidance of early trypsinization all appear to be important for survival of explanted(More)
The effect of paracetamol on mitochondrial function was studied using rat liver slices. Changes in the potential of the mitochondrial and plasma membrane were monitored using [3H]-triphenylmethylphosphonium (TPMP+) and [14C]thiocyanate (SCN-) probes, respectively. Liver slices were exposed to 10 mM paracetamol for various time periods (0-360 min) after(More)
Further investigation of the humoral immune responses of patients with sarcoma to their tumors revealed a sarcoma-associated antigen that was readily detected by complement fixation. Circulating levels of antibody to this antigen, tentatively labeled S3, rose markedly after surgical removal of the tumor. Antibody to S3, as to S1 and S2, was highly prevalent(More)
In the present study, we have examined the effect of dietary fat on paracetamol-induced liver injury in an in vitro rat liver slice model. Rats were fed, for 7-10 days, diets containing either butter or polyunsaturated vegetable margarine, two fat sources commonly consumed in the human diet. Liver slices were then exposed to paracetamol for 2 hr and further(More)
