Purpose of the review: This review highlights the role of angiogenesis, lymphangiogenesis, and immune markers in human immunodeficiency virus (HIV)-associated preeclamptic (PE) pregnancies in an attempt to unravel the mysteries underlying the duality of both conditions in South Africa. Recent findings: Studies demonstrate that HIV-infected pregnant women develop PE at a lower frequency than uninfected women. In contrast, women receiving highly active anti-retroviral therapy (HAART) are more inclined to develop PE, stemming from an imbalance of angiogenesis, lymphangiogenesis, and immune response. Summary: In view of the paradoxical effect of HIV infection on PE development, this study examines angiogenesis, lymphangiogenesis, and immune markers in the highly HIV endemic area of KwaZulu-Natal. We believe that HAART re-constitutes the immune response in PE, thereby predisposing women to PE development. This susceptibility is due to an imbalance in the angiogenic/lymphangiogenic/immune response as compared to normotensive pregnant women. Further large-scale studies are urgently required to investigate the effect of the duration of HAART on PE development.

The authors investigated the fertility of male and female rats exposed to a unique-design electromagnetic apparatus (Hivex Electromagnetic Field System-5 [EMFS-5]), which establishes an omni-directional, spatial field and has a wide band range of 100 MHz-3 GHz. We used 32 male and 32 female rats that were proven breeders. Sixteen rats from each sex were exposed to the EMFS for 8h/day for 10 days. The others were sham exposed. The rats were divided into the following 4 groups: in group AG1-AG8, males and females were exposed; in group AG9-AG16, only females were exposed; in group AG17-AG24, only males were exposed; and in group AG25-AG32, males and females were sham exposed. After exposure for each group, a male rat was cohabited with a female rat until parturition. The authors' results showed that except for 1 male, the fertility of all other rats was not affected. They did not see differences in reproductive ability (latency to parturition, litter size, number of male/female pups, male-to-female ratio, m...
