Cryogenic activity and stability of benzaldehyde lyase enzyme are achieved in lipidic mesophases, relying on the existence liquid water at subzero temperatures.

This review is an account of research into the biochemistry of lipids of platyhelminth parasites. Taking as high benchmark major metabolic pathways of vertebrates we summarize catabolic and synthesis routes now thought to be characteristic of this group. We emphasize the litlle recent information that exists on intermediary metabolism in these parasites. However, new data may be challenging old...

For the act of membrane fusion, there are two competing, mutually exclusive molecular models that differ in the structure of the initial pore, the pathway for ionic continuity between formerly separated volumes. Because biological "fusion pores" can be as small as ionic channels or gap junctions, one model posits a proteinaceous initial fusion pore. Because biological fusion pore conductance va...

Despite the key role of flavan-3-ols in many foods, very little is yet known concerning the modification of their chemical structures through food processes. Degradation of model media containing (-)-epicatechin and procyanidin B2, either separately or together, was monitored by RP-HPLC-DAD-ESI(-)-MS/MS. Medium composition (aqueous or lipidic) and temperature (60 and 90 °C) were studied. In aqu...

This study compares the effects of a single bout of exercise (acute extenuating) with those promoted by an exercise training program (chronic), focusing on low-grade chronic inflammation profile and on oxidative stress status, using the obese ZDF rats as a model of type 2 diabetes mellitus (T2DM). Animals were sacrificed after 12 weeks of a swimming training program and after a single bout of a...

Raman spectroscopy coupled with K-means clustering analysis (KMCA) is employed to elucidate the biochemical structure of human skin tissue sections and the effects of tissue processing. Both hand and thigh sections of human cadavers were analyzed in their unprocessed and formalin-fixed, paraffin-processed (FFPP), and subsequently dewaxed forms. In unprocessed sections, KMCA reveals clear differ...

This study investigates the influence of excess water on lipidic mesophase during phase transition from diamond cubic (Pn3m) to reverse hexagonal (HII). By a combination of...
