Antifungal drug kills TB bug

... eliminated by the 1960s, but is now resurgent and kills nearly two million people worldwide every year. New infections are occurring at a rate of one per second. Of equal concern is the dramatic rise in the incidence of new strains of TB that are resistant to traditional antibiotics. As a result, the W...

Cancer-killing invention also harvests stem cells

...and stem cells. When he captures cancer cells, he kills them. When he captures stem cells, he harvests th...esides outside of the body ?either way, the device kills cancer cells and captures stem cells, which grow into blood cells, bone, cartilage, and fat. When K...

Are one-third of costly implanted heart devices unnecessary? New study suggests yes

...and save patients from sudden cardiac death, which kills 300,000 Americans each year. But a new study finds that while many of these patients will benefit from their ICDs, a large number won't -- and a simple heart-rhythm test can tell who's who. In fact, the study suggests that if the test were used o...

Hybrid molecule causes cancer cells to self-destruct

...have developed a two-pronged molecular weapon that kills cancer cells in lab tests. The researchers cautioned that their double-punch molecule, described in the December issue of the journal Chemistry & Biology, has not yet been tested on animals or humans. Nevertheless, they believe it represents a pr...

LIAI completes world's most comprehensive analysis on influenza virus data

...ed on influenza because it is a major illness that kills 36,000 Americans each year and global concerns over the possible spread of the H5N1 avian flu. In the future, database information on other infectious diseases can also be analyzed and used to good effect." ...

Nanotextured implant materials: blending in, not fighting back

...p materials that will kill a cell ?no matter if it kills a bad cell or a good cell. We're trying to find materials that accept good cells, as opposed to killing off bad cells." Normal healthy blood vessels have a thin lining of specialized cells called the endothelium, surrounded by a thicker layer of s...

Major gene study uncovers secrets of leukemia

...this continual growth of leukemic cells eventually kills the child. "The new insights into the differentiation of B cells are extremely valuable," said Ching-Hon Pui, M.D., chair of the Oncology department and American Cancer Society Professor at St. Jude. Pui co-authored the paper. "The more we learn ...

Male-killing bacteria makes female butterflies more promiscuous

...ium is transmitted from mother to son and actually kills the son before the embryo hatches into a caterpillar. Only female offspring of female carriers of the bacteria can survive, which can lead to the male population being as low as one male to every hundred females in some areas. Dr Greg Hurst, of th...

It's never too late to get it back! Aging interrupted

...hought that the body does this because it normally kills some cells like damaged and rogue cancer cells to provide energy when it is starving. Then it replaces these cells when a meal is eaten. It seems it is the total number of calories which are consumed, rather than the type of food which is the ke...

Cornell lab confirms deadly fish virus spreading to new species

...ffected and so many mortalities." Three new fish kills have occurred in 2007 in New York waters since the virus was identified in the Great Lakes Basin in 2005. In the St. Lawrence River, hundreds of thousands of round gobies have succumbed to the disease; gizzard shad die-offs from VHSV in Lake Ontario ...

Gene thought to assist chemo may help cancer thrive

...ired, p53 starts a process known as apoptosis that kills the cell. It's p53's role as one of the genes involved in initiating cell death that has led cancer researchers to long believe that the gene is essential to successful chemotherapy. The idea is that p53 assists in killing the cancerous cells that th...

Simple home spit test to spot deadly pre-eclampsia

..., which can be symptomless in the early stages but kills 1000 babies in the UK every year. The test is expected to be more reliable than the traditional blood pressure and urine tests conducted in GPs' offices and hospitals. Pre-eclampsia is also a leading cause of maternal mortality, killing one woman g...

Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host

...he whole genome of the bacteria to work out how it kills its host," said Professor Stuart Reynolds from the University of Bath. "People studying diseases think that the kind of gene-for-gene interaction between pathogen and host that we have found is quite common, but actually rather few are known, whi...

HIV and malaria combine to adversely affect pregnant women and their infants

...a is a parasitic disease spread by mosquitoes that kills more than one million people every year. While the disease affects mostly children, malaria also severely affects pregnant women, especially during their first pregnancy, accounting for an estimated 400,000 cases of severe anaemia and 200,000 infant ...

Genome of Clostridium botulinum reveals the background to world's deadliest toxin

... own ‘antibiotic’ — a chemical called boticin that kills competing bacteria." Genome sequences can tell us a lot about the biology of the organism, but research into clostridia has been hampered by the lack of a good genetic system. Professor Nigel Minton, Professor of Applied Molecular Microbiology at ...

Modified mushrooms may yield human drugs

...d the mushroom cells to hygromycin. The antibiotic kills all the normal cells, separating out those that have been genetically altered for resistance. The test demonstrates that if a second gene, insulin for example, were to be patched in the plasmid, that gene would be expressed as well. "There is ...

New study reports hotel guests at risk from carbon monoxide poisoning

Carbon monoxide (CO) poisoning kills over 200 people every year in the United States. Although inexpensive CO detectors have been available since 1989, their use in hotels, motels and resorts is not widespread. In fact, while every guest room in the U.S. must contain a smoke detector, t...

Cells re-energize to come back from the brink of death

... In turn, caspases trigger a series of events that kills the cell. Mitochondria are tiny structures that act as power plants to supply the cell with energy, but also hold the keys to the cells’ life and death. The process by which the membranes develop holes—mitochondrial outer membrane permeability ...
