background: acid phosphatase (acp) is suggested to be one of the virulence factors in leishmania and a correlation has been reported between leishmanial acid phosphatase (acp) activity and the severity of the disease in all types of leishmaniasis including zoonotic cutaneous leishmaniasis (zcl), which is a polymorphic disease.   objective : characterization of leishmania and its correlation wit...

Planaria reproduce by transverse fission. Isolated worms increase in number exponentially, while social animals at the same density are inhibited in terms of numerical increase, but over a 25 day period undergo a larger increase in mass. Isolated posterior fission products reproduce faster than isolated anterior fission products. Regulation of population growth is independent of density over a ...

We previously reported that mast cells express renin, the rate-limiting enzyme in the renin-angiotensin cascade. We have now assessed whether mast cell renin release triggers angiotensin formation in the airway. In isolated rat bronchial rings, mast cell degranulation released enzyme with angiotensin I-forming activity blocked by the selective renin inhibitor BILA2157. Local generation of angio...

Abstract Mersicarpine is an aspidosperma alkaloid isolated from the Kopsia genus of plants. Its intriguing structural features have attracted much attention in synthetic organic chemistry, but no biological activity has been reported. Here, we report effects mersicarpine on human leukemia cell line HL60. At concentrations above 30 µm, reversibly arrested cycle progression S-phase. higher concen...
