Essais preliminaires d'utilisation des cryoprotecteurs dans les pulpes de poisson. ArchiMer
Tran, Van Dan; Han-ching, Luçay.
The various ways of protein denaturation during frozen storage of fish and the theoretical chemical means of cryoprotection are described. Then the effects on protein solution and fish mince of several additives and binders are tested especially with low sweetness chemical agents produced by sugar industry.

Partially folded intermediates during trypsinogen denaturation BJMBR
Martins,N.F.; Santoro,M.M..
The equilibrium unfolding of bovine trypsinogen was studied by circular dichroism, differential spectra and size exclusion HPLC. The change in free energy of denaturation was <img SRC="http:/img/fbpe/bjmbr/v32n6/3282sup.gif" ALIGN="BOTTOM" BORDER="0" VSPACE="0" HSPACE="0"> = 6.99 ± 1.40 kcal/mol for guanidine hydrochloride and <img SRC="http:/img/fbpe/bjmbr/v32n6/3282sup.gif" ALIGN="BOTTOM" BORDER="0" VSPACE="0" HSPACE="0"> = 6.37 ± 0.57 kcal/mol for urea. Satisfactory fits of equilibrium unfolding transitions required a three-state model involving an intermediate in addition to the native and unfolded forms. Size exclusion HPLC allowed the detection of an intermediate population of trypsinogen whose Stokes radii varied from 24.1 ± 0.4 Å to...

Evaluation of in vitro and in vivo therapeutic efficacy of Ribes alpestre Decne in Rheumatoid arthritis BJPS
Hasan,Alamgeer Umme Habiba.
Rheumatoid arthritis is an autoimmune inflammatory disorder, despite the discovery of numerous drugs there is still need to introduce newer, safer and more effective sources of drugs such as medicinal herbs. Present research work was an attempt to appraise the antiarthritic potential of Ribes alpestre Decne in rheumatoid arthritis. In vitro inhibition of protein (bovine serum albumin and egg albumin) denaturation, Human red blood cell membrane stabilization assays along with formaldehyde induced arthritis in rats were commenced in this study. Findings of present investigation demonstrated significant and dose dependent antiarthritic effect of Ribes alpestre. Aqueous ethanolic extract, butanol and aqueous fraction illustrated 95%, 69.233% and 92.840%...
