A new investigation into Napoleon Bonaparte?s cause of death might finally put to rest nearly 200 years of lingering mysteries about the illness that killed the French emperor during his island exile, a UT Southwestern Medical Center scientist reports.
Dartmouth Medical School researchers have identified a new way that arsenite, a form of arsenic, acts in treating a rare cancer known as APL, or acute promyelocytic leukemia. Their study is published in the Jan_3 issue of the Journal of the National Cancer Institute.
There are few treatments for a rare cancer called acute promyelocytic leukemia (APL). Arsenite is a form of arsenic that’s particularly effective against this cancer. In a new study, researchers identify a novel mechanism by which arsenite acts in APL cells.
UC Berkeley scientists Jill Banfield and Brett Baker have found some of the smallest organisms known in a sample of slime from a California mine. Their discovery proves the value of a technique called “shotgun” sequencing to identify all organisms in a microbial community, particularly those too small to see in a microscope, those very low in abundance, or those too novel to be picked up by PCR.
THE British public is unaware of the multitude of poisonous chemicals found in cigarette smoke – according to a survey carried out for Cancer Research UK.
Dartmouth researchers report that three different steroid hormones all show similar responses to arsenic, suggesting a broader effect and a common mechanism of arsenic on how these hormones function.
Researchers from TU Delft and FOM Foundation have successfully measured transport through a single atom in a transistor. This research offers new insights into the behavior of so-called dopant atoms in silicon. The researchers are able to measure and manipulate a single dopant atom in a realistic semi-conducting environment. The individual behavior of dopant atoms is a stumbling block to the further miniaturisation of electronics. The work is published in Physical Review Letters.
Chemotherapy for breast cancer was first introduced 30 years ago, and doctors have been refining the treatment ever since. Countless studies have asked which drugs work best and when they should be given, but many women still have not realized the full benefits of chemotherapy.
Long-term consequences of arsenic poisoning during infancy is due to contaminated milk powder, a study published in Environmental Health by Miwako Dakeishi, Katsuyuki Murata and Philippe Grandjean. Arsenic toxicity is a global health problem affecting many millions of people.
Homoeopathic system of medicine can treat and prevent dengue fever (DF) and dengue hemorrhagic fever (DHF) by immuno-modulation of the patients without any side and adverse effects. Homeopathy has been used successfully in the others countries apart from India in the past. The selection of homoeopathic drugs in these cases depends upon the individual response to infection and virulence of the virus. The symptomatology of the patients those who are having dengue fever and dengue hemorrhagic are studied to decide about the curative and preventive homoeopathic medicines for any patient as well as epidemic as a whole.
