Overtreatment of malaria in central, south Asia leading to neglect of other diseases, study finds

"Over diagnosis and mistreatment of malaria in central and south Asia may be widespread, leading to the neglect of other serious illnesses, according to a new study from Afghanistan," published in the British Medical Journal last month, SciDev.Net reports.

Scientists dissect how sperm cells of the fruit fly build their flagella

Sperm swim, lung cells sweep mucus away, and the cells in the female Fallopian tube move eggs from the ovary to the uterus. Underlying these phenomena are flagella - slender, hair-like structures extending from the surface of the cells, that bend, beat or wave rhythmically. In the latest issue of the journal Developmental Cell, scientists from the Instituto Gulbenkian de Ciência (IGC), in Portugal, have dissected how sperm cells of the fruit fly build their flagella.

New life for forgotten technique in detecting resistant tuberculosis

Scientists of the Antwerp Institute of Tropical Medicine have breathed new life into a forgotten technique and so succeeded in detecting resistant tuberculosis in circumstances where so far this was hardly feasible. Tuberculosis bacilli that have become resistant against our major antibiotics are a serious threat to world health.

New method gives precise picture of how immune system works

Chronic infections are a large and growing problem throughout the developed world, and intensive research is being conducted in ways to combat the recalcitrant bacteria. When bacteria aggregate into so-called biofilm, they become resistant to antibiotics. Until now scientists have only been able to speculate about what happens when bacteria overpower the immune system during a chronic infection.

Malaria misdiagnosis: an interview with Dr Toby Leslie

Malaria is caused by a multi-staged parasite which is transmitted by the bite of infected female anopheles mosquitoes. It affects millions of people and kills more than 500,000 people throughout the world every year.

Malaria commonly misdiagnosed and mistreated in Afghanistan

Findings published in the BMJ suggest that malaria is being significantly misdiagnosed in Afghanistan, with many patients with fever alone being given antimalarial drugs and antibiotics despite having negative laboratory results for the disease.

Neural precursor cells suppress aggressive tumors

Neural precursor cells (NPC) in the young brain suppress certain brain tumors such as high-grade gliomas, especially glioblastoma (GBM), which are among the most common and most aggressive tumors.

New NMR spectrometer to benefit researchers from across Texas A&M

Top-notch molecular research swung into gear at Texas A&M University this week - literally. A crane lowered a high-field 800 megahertz Nuclear Magnetic Resonance spectrometer through an opening in the roof of a biochemistry and biophysics building Wednesday, putting the university on par with leading U.S. research institutions, according to Dr. Gregory Reinhart, department head.

Scientists capture high-quality images of immune cell trafficking in a beating heart

Blood flow to the heart often is interrupted during a heart attack or cardiac surgery. But when blood flow resumes, the heart may still falter. That's because collateral damage can occur as blood re-enters the heart, potentially slowing recovery and causing future cardiac troubles.

Cells close to death from toxin exposure can survive when toxins are removed

The vast majority of cells that appear to be on a one-way track to death after exposure to toxins can bounce back completely after those toxins are removed, Johns Hopkins scientists report in a new study. The finding, published in the June 15 issue of Molecular Biology of the Cell, is not only a testament to the indomitable cellular spirit, but could also offer some practical insight on how to save dying tissues after heart attacks or strokes as well as prevent cancer in cells transiently exposed to toxins.
