'Tradition', person, gender, and STD/HIV/AIDS in southern Mozambique.

In southern Mozambique, the "traditional" notion of personhood is constructed through a process, as an outcome of diachronic and synchronic social relations that encompass kin and other peers, including spirits. Both person and body are thought of as elements traversed and determined by these relations, which include the gender relations whose complementarity finds expression in alliances and the production of descendants. In this system of agnatic kinship, descent is possible through women, who produce the male and female persons.

Identification of Pseudomonas aeruginosa genes involved in virulence and anaerobic growth.

Pseudomonas aeruginosa is a gram-negative, opportunistic pathogen and a significant cause of acute and chronic infections in patients with compromised host defenses. Evidence suggests that within infections P. aeruginosa encounters oxygen limitation and exists in microbial aggregates known as biofilms.

Effect of anaerobiosis and nitrate on gene expression in Pseudomonas aeruginosa.

DNA microarrays were used to examine the transcriptional response of Pseudomonas aeruginosa to anaerobiosis and nitrate. In response to anaerobic growth, 691 transcripts were differentially expressed. Comparisons of P.

Microarray analysis of Pseudomonas aeruginosa quorum-sensing regulons: effects of growth phase and environment.

Bacterial communication via quorum sensing (QS) has been reported to be important in the production of virulence factors, antibiotic sensitivity, and biofilm development. Two QS systems, known as the las and rhl systems, have been identified previously in the opportunistic pathogen Pseudomonas aeruginosa. High-density oligonucleotide microarrays for the P.
