Characterization and screening of microsatellite loci in a wild lemur population (Propithecus verreauxi verreauxi).

Sixteen dinucleotide microsatellite loci were isolated from the genome of Propithecus verreauxi verreauxi. All loci were polymorphic when genotyped on a minimum of 16 animals. The number of alleles across these loci ranges from two to 11. Additionally, seven of these loci were genotyped across a minimum of 200 animals in order to estimate heterozygosity and their potential for parentage assignment in this population. Using these seven loci, the mean heterozygosity in this population is 0.705, and the combined probability of these seven loci to exclude a random individual from parentage, when one parent is known, is 0.996. These data suggest that these loci will be useful for estimating a variety of population genetic and genealogical parameters in P. v. verreauxi populations.

Monocyte/macrophage regulation of coagulant events.

Monocytes/macrophages actively regulate both the assembly and function, as well as the substrate specificity, of various coagulation enzymes at their membrane surface. Regulation is effected through a variety of mechanisms, not limited to, but including the expression of receptors (or 'binding sites') for the various protein constituents of the complexes, the expression of different receptors which may alter the function of the protease, and the expression of membrane proteases which may affect protein cofactor function. Monocyte stimulation with various agonists modulates many of these responses as does their adherence to and differentiation on various substrates.
