Cellulase, an enzyme that helps soften fruit peel, is produced by plants during the fruit ripening phase. Utilizing the immersing water from the white pepper processing to extract cellulase will help minimizing environmental waste and retrieving valuable compounds. Some factors affecting the cellulase yield from the immersing water of pepper were studied, including the degree of ripeness of peppercorn, immersing temperature and time.

The superabsorbent polymers based on acrylic acid have been prepared in the presence of ammonium persulfate (APS) as initiator and N,N-methylene- bis- acrylamide (MBA) as crosslinking agent. The suspension polymerisation occurred in aqueous drops dispersed in toluene and stabilised by sorbitan monooleate. Some effects on the swelling degree and size particles such as concentrations of MBA and initiator, neutralization degree (Dn) were studied. Swelling degree 405g/g, reach maximum at 85◦C and 0.09% crosslinking agent, 1.

Akt regulates various cellular processes, including cell growth, survival, and metabolism. Recently, Akt's role in neurite outgrowth has also emerged. We thus aimed to identify neuronal function-related genes that are regulated by Akt. Methods: We performed suppression subtractive hybridization on two previously established PC12 sublines, one of which overexpresses the wild-type (WT) form and the other, the dominant-negative (DN) form of Akt. These sublines respond differently to NGF's neuronal differentiation effect. Results: A...
