Many amyloid inhibitors resemble molecules that form chemical aggregates, which are known to inhibit many proteins. Eight known chemical aggregators inhibited amyloid formation of the yeast and mouse prion proteins Sup35 and recMoPrP in a manner characteristic of colloidal inhibition. Similarly, three known anti-amyloid molecules inhibited b-lactamase in a detergent-dependent manner, which sugg...

1997 Vitamin D is converted in the liver by a vitamin D-25-hydroxylase (25-OHase) to form the major circulating form of vitamin D, 25-hydroxyvitamin D [25(OH)D]. There have been at least four different 25-OHases identified both in mitochrondia and in microsomes. 25(OH)D is, however, biologically inert and requires hydroxylation in the kidneys on carbon 1 by the CYP27B mitrochondrial enzyme 25-h...

Multiple lines of evidence indicate that important functional properties are embedded in the non-coding portion of the human genome, but identifying and defining these features remains a major challenge. An initial estimate of the magnitude of functional non-coding DNA was derived from comparative analysis of the first available mammalian genomes (human and mouse), which indicated that fewer th...

Navitoclax (ABT-263), a Bcl-2 family inhibitor and ABT-199, a Bcl-2 selective inhibitor, are high molecular weight, high logP molecules that show low solubility in aqueous media. While these properties are associated with low oral bioavailability (F), both navitoclax and ABT-199 showed moderate F in preclinical species. The objective of the described study was to determine if lymphatic transpor...

The development and quality of ovine zygotes derived from in vivo (IVOF) or in vitro fertilization (IVF) were compared after coculture on sheep oviductal cells. The same criteria were used to evaluate the coculture of IVF zygotes in CZB medium for 2 d followed by 199 medium for 6 d (CZB-199 coculture) or in 199 medium for 8 d (199 coculture). A higher overall developmental rate to blastocyst st...
