Jasminum amplexicaule Buch-Ham. (Oleaceae) has been commonly used in the traditional medicine in dysentery, diarrhoea and bellyache in China. In the present work, the methanol extract of Jasminum amplexicaule (JME) was examined for pharmacology on human colonic epithelial cell line T84 by the short-circuit current technique. The results showed that pretreatment of T84 cells with JME produced a ...

D-004, a lipid extract of Roystonea regia fruits that contains oleic, lauric and myristic acids as major components inhibits alpha1-adrenoreceptors-mediated contractile responses in isolated rat vas deferens and prostate trips; no study has demonstrated a similar effect for oleic, lauric or myristic acids individually. Therefore, the effects of D-004 (250 microg/mL), oleic (100 microg/mL), laur...

Reactivation of Kaposi's sarcoma-associated herpesvirus (KSHV) lytic replication is mediated by the viral RTA transcription factor, but little is known about the physiological processes controlling its expression or activity. Links between autonomic nervous system activity and AIDS-associated Kaposi's sarcoma led us to examine the potential influence of catecholamine neurotransmitters. Physiolo...

A novel spatial environment consists of several different types of information that may be encoded by cellular information storage mechanisms such as long-term potentiation (LTP) and long-term depression (LTD). Arousal, mediated, for example, by activation of the noradrenergic system, is a critical factor in information acquisition and may enhance the encoding of novel spatial information. Usin...

Heart rate recovery (HRR) after exercise is an independent predictor of adverse cardiovascular outcomes. HRR is mediated by both parasympathetic reactivation and sympathetic withdrawal and is highly heritable. We examined whether common genetic variants in adrenergic and cholinergic receptors and transporters affect HRR. In our study 126 healthy subjects (66 Caucasians, 56 African Americans) pe...

Lung tissue may be an important source of systemic inflammation associated with sepsis and the acute respiratory distress syndrome (ARDS). An ex vivo model of freshly explanted lung tissue in culture was developed to evaluate the ability of lipopolysaccharide (LPS) to directly stimulate lung tissues under conditions where indirect mechanisms such as recruitment of blood-derived inflammatory cel...
