Can mouthwash stop malaria?

By | February 2, 2001

Triclosan, a common ingredient of mouthwashes, inhibits the growth of Plasmodium falciparum in vitro and P. berghei in a mouse model. Resistance is rapidly developing to the few remaining anti-malarial drugs and thus new therapies are urgently needed. In the February Nature Medicine, researchers from Jawaharlal Nehru Centre for Advanced Scientific Research, India, investigate the commonly used antibiotic Triclosan as an effective treatment for malaria.Namita and Avadhesha Suriola found that an i

Gas6 blockade stops fatal thrombosis

By | February 2, 2001

Gas6 is a platelet-response amplifier that, if inhibited, protects from thrombosis without inducing bleeding. Deep vein thrombosis (DVT) is a common condition that can be fatal if fractions of the clot break off and lodge in the arteries of the lungs. Heparin, warfarin and aspirin prevent clot formation but may induce bleeding.In the February Nature Medicine researchers from the Centre for Transgene technology and Gene Therapy at Flanders Interuniversity Institute for Biotechnology, Belgium, de

Array-of-arrays

By | February 1, 2001

The lack of molecular markers is a major factor contributing to the poor diagnosis and survival of women suffering from epithelial ovarian cancer. As reported in the January 30 Proceedings of the National Academy of Science, Welsh et al. identified groups of genes whose expression correlated with clinical observations and therefore might be useful diagnostic markers for ovarian cancer (Proc Natl Acad Sci USA 2001, 98:1176-1181). They developed a high-throughput protocol (which they have termed '

Signalling lymphangiogenesis

By | February 1, 2001

Vascular endothelial growth factors signal the development of tumour-induced lymph vessel growth and enhance lymphatic metastasis in vivo.A poorly understood characteristic of cancerous tissue is its ability to develop lymphatic tissue by the process of lymphangiogenesis. This is an important consideration because this contributes to the cancer's ability to metastasise through the body. In the February Nature Medicine, three separate research groups provide direct evidence that two recently clon
