Pediculus humanus capitis: an update

Head lice infestation, or pediculosis capitis, caused by Pediculus humanus capitis, is a common health concern. In the US, where pediculosis capitis is the most prevalent parasitic infestation of children, 6 to 12 million people are affected every year. Pediculosis capitis remains confined to the scalp. Scalp pruritus is the cardinal symptom, although patients with lice can be asymptomatic. Pru...

Homo Socialis and Homo Sapiens

The assumption that individuals are behaving rationally can, at times, usefully constrain predictions of individual and collective behavior. However, success in predicting human and group behavior will often require relaxing this assumption of rationality, instead employing evolutionary, neural, and cognitive constraints. One particularly important form of neural and cognitive constraint is tha...

Molecular Evolution of Pediculus humanus and the Origin of Clothing

The human head louse (Pediculus humanus capitis) and body louse (P. humanus corporis or P. h. humanus) are strict, obligate human ectoparasites that differ mainly in their habitat on the host : the head louse lives and feeds exclusively on the scalp, whereas the body louse feeds on the body but lives in clothing. This ecological differentiation probably arose when humans adopted frequent use of...

Extraction of Biological Motifs by Gibbs Sampler from the Promoters of Homo Sapiens, Saccharomyces cerevisiae and Bacillus subtilis

Microarray analysis provides us with new information about genes regulatory network, and many novel candidates of co-regulated genes are being identified. It is assumed that co-regulated genes share cis-acting regulatory motifs in their upstream regions, and it is still a big challenge for many bioinformaticians to develop an algorithm for their accurate elucidation. Although many motif extract...
