Abstract:

Chrome (VI) has a high level of toxicity. Formaldehyde is potential to be developed as a substitute of chrome tanning agent. The aims of this study are to explain the amount of formaldehyde bound, shrinkage temperature, tensile strength, and tear strength on Mondol stingray (Himantura gerrardi) leather. Pickled mondol stingray has been used as raw material. The study was divided into 4 treatments, that is P.I (formaldehyde 2%), P.II (formaldehyde 4%), P.III (formaldehyde 6%), and P.IV (formaldehyde 8%). The method used is drum tanning. Shrinkage temperatures, tensile strength and tear strength

Abstract:

The neisserial porin P.I is a GTP binding protein that forms a voltage-gated channel that translocates into mammalian cell membranes and modulates host cell signaling events. Here, we report that P.I confers invasion of the bacterial pathogen Neisseria gonorrhoeae into Chang epithelial cells and that this event is controlled by GTP, as well as other phosphorus-containing compounds. Bacterial invasion was observed only for strains carrying the P.IA subtype of porin, which is typically associated with the development of disseminated neisserial disease, and did not require opacity outer membrane

SUMMARYThe activity of the gluconeogenic enzyme, alanine-amino-transferase (ALT), in a preparation from the liver of rats was studied by means of an in vitro assay throughout the course of a primary infection of Nippostrongylus brasiliensis, established by a subcutaneous injection of approximately 4000 3rd-stage larvae. The activity was measured on days 1–14 p.i. in both uninfected and infected rats and a marked pattern in the enzyme's activity was observed. In infected rats, the activity increased from 1·46±0·19 U/g liver on day 1 p.i. to a peak on day 4 p.i. of 10·75±1·62 U/g liver, then dec

ABSTRACT We have recently identified a DNA-binding protein (DBP) from the baculovirus Bombyx mori nucleopolyhedrovirus (BmNPV) which can destabilize double-stranded DNA (V. S. Mikhailov, A. L. Mikhailova, M. Iwanaga, S. Gomi, and S. Maeda, J. Virol. 72:3107–3116, 1998). DBP was found to be an early gene product that was not present in budded or occlusion-derived virions. In order to characterize the localization of DBP during viral replication, BmNPV-infected BmN cells were examined by immunostaining and confocal microscopy with DBP antibodies. DBP first appeared as diffuse nuclear staining at

Changes in neutral lipid content of developing female gametes in Heligmosomoides polygyrus at 8, 12, 20, 40, 80, and 140 days postinfection (p.i.) were investigated and correlated with egg production by the worms over the same period. Egg production increased to day 20 p.i. when the average egg output for one female reached approximately 700 eggs/day. A decline in egg production occurred from 80 days p.i. until the end of the experiment (140 days p.i.). Neutral lipid content was low in oogonia from worms of all ages. Developing oocytes contained the highest levels of neutral lipid. There was a

Anthracnose, caused by Colletotrichum coccodes, is a serious ripe tomato fruit rot disease. Genetic resistance to anthracnose is not available in commercial tomato cultivars, but has been reported in small-fruited Plant Introductions (P.I.), and with lesser intensity in a number of breeding lines. Transfer of high levels of resistance from these breeding lines or P.I.s to elite materials has proven difficult. Inheritance of resistance has been described as complex with at least six loci influencing resistance reactions. Segregating populations originating from a cross between a susceptible tom
