Ample research has demonstrated the largely untapped potential of bioactive peptides (BAPs) for treating systematic chronic inflammation (SCI). Protein hydrolysates are the mixture of peptides resulting from the hydrolytic breakdown of a protein. Numerous hydrolysates contain BAPs and exert beneficial effects in both in vitro and in vivo models. In...
A major challenge to the study of the peopling of the Americas is that much of the Bering Land Bridge (Beringia), the geographic area that people migrating from Northeast Asia into North America would presumably have passed through, is now submerged due to sea-level rise since the last glacial maximum....
Obtaining accurate estimates of animal abundance is made difficult by the fact that most
animal species are detected imperfectly. Early attempts at building likelihood models that
account for unknown detection probability impose a simplifying assumption unrealistic for
many populations, however: no births, deaths, migration or emigration can occur in the...

Biliary excretion of taurocholate in thermally acclimated rainbow trout was stimulated at higher environmental temperature (18 vs. 14 or 10° C)e Acute 4° C shifts in body temperature produced more pronounced changes in biliary excretion. Thermally modulated biliary excretion was negatively correlated with plasma half live of taurocholate. Absorption of...
A simultaneous direct spectrophotometric method for the determination
of barium and strontium using Sulfonazo III has been developed
making use of the chelons EGTA and CDTA at controlled pH
values.
An absorbance study of the barium and strontium complexes of
Sulfonazo III revealed that there is no pH sensitivity of...
The microdistribution of the amphipod Eohaustorius brevicuspis was
examined over a 19 month period. Field sampling was conducted principally
at Lost Creek State Park, Oregon, and on one occasion at Driftwood State
Park, Oregon. Both are high-energy, fine sand beaches which appear to be
uniform. Stratified random samples were taken...
Unpaved roads are a critical form of infrastructure in forested landscapes but also a potential source of fine sediment that can degrade sensitive ecosystems nearby. Improved management of aggregate road surfacing can reduce sediment generation, lengthen its useful life span, reduce maintenance costs, and more importantly, mitigate the impacts of...
