ANP Bioactivity in Obese Hypertensives To the Editor: I write to comment on and to question features of the recent publication from Dessi-Fulgheri and colleagues that appeared in the February issue of Hypertension (Hypertension. 1999:33;658–662). The authors report that a bolus injection of ANP produces greater falls in blood pressure, greater increases in plasma cyclic GMP, and a greater suppr...

Malaria, one of the most widespread diseases, is caused by a plasmodium parasite million people each year, results in several million deaths annually. protozoa that cause malaria, no one antimalarial drug is effective against all four species. research investigation, we performed antimalarial agents. To design a new molecule having good pha information. Key-words: TPSA, GPCR, ADMETox, Malaria i...

Yuanhu Zhitong Tablet (YZT) is an example of a typical and relatively simple clinical herb formula that is widely used in clinics. It is generally believed that YZT play a therapeutical effect in vivo by the synergism of multiple constituents. Thus, it is necessary to build the relationship between the absorbed fingerprints and bioactivity so as to ensure the quality, safety and efficacy. In th...

Anti-convulsant treatment is associated with a high prevalence of reproductive dysfunction compared with age-matched non-epileptics. We examined the widely used anti-convulsants valproate (VPA) and carbamazepine (CBZ) for steroidal bioactivity using a yeast-based steroid receptor-beta-galactosidase reporter assay for the androgen receptor (AR), progesterone receptor (PR) or estrogen receptor (E...

Estrogen and progesterone induce production of macrophage colony-stimulating factor (CSF-1) by uterine epithelial cells, and CSF-1 is produced in the uterus during pregnancy in mice. CSF-1 is a lineage-specific stimulator of macrophage proliferation, chemotaxis, and function. High concentrations of macrophages accumulate in the uterus during pregnancy. Experiments were conducted to determine wh...

Platelet-activating factor (PAF), the potent phospholipid mediator of inflammation, is involved in atherosclerosis. Platelet-activating factor-acetylhydrolase (PAF-AH), the enzyme that inactivates PAF bioactivity, possesses both acetylhydrolase and transacetylase activities. In the present study, we measured acetylhydrolase and transacetylase activities in human atherogenic aorta and nonatherog...

Anti-NogoA is a promising anti-inhibitory molecule that has been shown to enhance functional recovery after spinal cord injury when delivered in rat and primate models over the span of weeks. To achieve this sustained release, anti-NogoA is typically delivered by osmotic minipumps; however, external minipumps are susceptible to infection. To address this issue, we developed a drug delivery syst...

Molecular target identification is of central importance to drug discovery. Here, we developed a computational approach, named bioactivity profile similarity search (BASS), for associating targets to small molecules by using the known target annotations of related compounds from public databases. To evaluate BASS, a bioactivity profile database was constructed using 4296 compounds that were com...

BACKGROUND Rice vinegar (RV) and white vinegar (WV) as daily flavoring, have also used as accessory in traditional Chinese medicine processing. As we know, the promoting blood circulation efficiency could be enhanced when herbs processed by vinegar. Number of reports focused on health benefits derived by consumption of vinegar. However, few concerned the blood circulation bioactivity. METHODS...
