Merits and risks of postmenopausal hormone therapy

The study was categorized as a primary prevention trial for coronary heart disease, although the fact that mean age at recruitment was 63 years was not given enough importance at that time. WHI investigators concluded that hormone therapy (HT) was not cardioprotective, and, in fact, its riskbenefit ratio did not favor the use of postmenopausal hormones for prevention of chronic diseases.

Cancer cells can be killed by a new cancer drug that is triggered by a laser light

Their paper describes how these new photosensitizer drugs can only be activated by light once they have been localized in the target tumour cells. For the first time Zheng and Wilson have demonstrated that tumour cells can be selectively attacked using a PDT.
