We previously reported that alcohol drinkers with and without cirrhosis showed a significant increase in fecal bile acid secretion compared to nondrinkers. We hypothesized this may be due to activation by alcohol of hepatic cyclic adenosine monophosphate responsive element-binding protein 3-like protein 3 (CREBH), which induces cholesterol 7α-hydroxylase (Cyp7a1). Alternatively, the gut microbi...

A procedure for the preparation of spinach leaf mitochondria was deve loped. The procedure com bines d ifferential centrifugation, partition in dextranpolyethyleneglycol two-phase syste m and Percoli density gradient centrifugation. The d ifferent steps separate the material mainly according to size, surface properties and density, respectively. No chlorophyl l was present in the final mitochon...

Oxida t ion of the reduced p r i m a r ) e lec t ron acceptor , Q~-, of Pho tosys tem !I (PS I!) in f e rma te t r e a t ed sp inach thylakoids , was inhib i ted more af te r the second than af te r the f irst ac t in ic f lash.

The electrochemistry and ecl o f chlorophyl l a (Chl a) have been studied in highly pur i f ied D M F solutions. Cyc l ic voltammetric and coulometric experiments demonstrate that both the radical anion, (Chl a)-., and the dianion, (Chl a)2-, are fa i r ly stable even under bulk electrolysis conditions in the absence o f proton donors and oxygen. The protonation o f ( C H I a)-. and ( C h l a)*...

Carbon assimilation, translocation, and associated biochemical characteristics of the second trifoiolate leaf (numbered acropetally) of chambergrown soybean, Glycine max (L.) Meff., plants were studied at selected stages of leaf development during the period from 10 to 25 days postemergence. Leaves of uniform age were selected on the basis of leaf plastochron index (LPI). The test leaf reached ...
