In 1983, during the earliest days of AIDS research, Deborah Anderson and her colleagues in Boston, Massachusetts hypothesized that AIDS was transmitted by virallyinfected "Trojan horse leukocytes" in semen [1]. This prediction has been supported by numerous studies over the past two decades, although many questions remain concerning HIV infection of the male genital tract. In this issue of AIDS...

Seminal plasma is a potential source of biomarkers for many disorders of the male reproductive system including male infertility. Knowledge of the peptide and protein components of seminal fluid is accumulating especially with the appearance of high-throughput MS-based techniques. Of special interest in the field of male infertility biomarkers, is the identification and characterization of diff...

the use of quantum dots (qdots) as bright and photostable probes for long-term fluorescence imaging is gaining more interest. thus far, (pre)clinical use of qdots remains limited, which is primarily caused by the potential toxicity of qdots. most qdots consist of cd2+ ions, which are known to cause high levels of toxicity. therefore, the cytotoxic effects of cdse quantum dots on embryonic devel...
