FDA Approves Vectibix for Colorectal Cancer

... has been found in 70% of the cancers and Vectibix acts by targeting it. The approval was granted after conducting a randomized and controlled clinical trial on 463 patients.The cancer had spread to other parts of the body and did not respond to conventionally used drugs like Oxaliplatin, Irinotecan and...

New Path from Estrogen to Survival in Breast Cancer Cells Described

...e cell is to apoptosis. * Estrogen, a hormone that acts as growth fuel for about 70 percent of breast cancers. Researchers are interested in ways that cells can efficiently turn genes on or off, and one of the newest mechanisms is dubbed "NEDDylation," which Yeh helped to find 10 years ago. This process...

Insight Into Tanning Process Suggests Novel Way to Prevent Skin Cancer

...irectly on the nuclei of melanocytes, UV radiation acts on keratinocytes (the most abundant as well as superficial cells in the skin), causing them to produce and secrete MSH, which attaches to adjacent melanocytes and starts the pigment-making process. While Fisher's model adequately explains why redhe...

Child death reduction needs five times more funds

...l the MDGs," he writes in a commentary. "This goal acts as a spotlight for many neglected diseases, as well as a litmus test for the achievement of other MDGs." GYT...

Raloxifene Reduces The Risk Of Breast Cancer

... the duration and concentration of estrogen, which acts as a tumour promoter in the majority of breast cancers,' said Dr. Lippman. The research team conducted a new analysis of the first large study of raloxifene, which tested the ability of the drug to prevent vertebral fractures in 7,705 postmenopausa...

Nanotech Wipes for biohazard detection

... the conventional fibres. ‘The fabric basically acts as a sponge that you can use to dip in a liquid or wipe across a surface,’ Frey said. ‘As you do that, antibodies in the fabric are going to selectively latch onto whatever pathogen that they match. Using this method we should, in theory, be able to ...

A New drug Developed To Fight The Bio-Terrorism Threat Of VEE Virus

...tists focused on is known as the nsP2 protease. It acts like a pair of molecular scissors, chopping another complex of VEE proteins into specific smaller protein molecules that work together to transform living cells into VEE virus factories. "This protein is crucial to VEE virus replication, and we want ...

Cancer-Killing Viruses Employ Multiple Mechanisms

...st line of defense, the skin and mucous membranes, acts as a physical barrier. The second layer is the innate immune system, a broad-acting, short-term, non-specific immune response to pathogens such as bacteria or viruses. Microbes that evade the innate system encounter a third layer of protection; a sec...

Key component of sunscreen heals sunburn and prevents skin cancer

... “The UVA component of sunlight is dangerous as it acts as an oxidising agent that forms free radicals which trigger chain reactions that potentially lead to DNA damage that can convert healthy skin cells into cancerous ones.” The original research paper, 'Caged-Iron Chelators a Novel Approach Towards ...

Prison inmates plagued by mental problems

Fimbriae Help Bacteria Stick Around Inside the Body

...e FimH-sugar combination makes a 'catch bond' that acts like a finger trap, and actually gets stronger as drag force is exerted on a bacterium. Rather than being swept away by fluids moving through the human body, the bacterium grips even more tightly, helping it stick around and form an infection, like t...

Feedback Loop Governing Ovarian Development Unraveled

Indian Doctor in Britain Jailed for Molesting Patients

... of examinations but involved 'quite overt' sexual acts as well. Deodhar was convicted of two charges of indecent assault against Mrs B, a 41-year-old mother of four who went to discuss an abortion. After carrying out an inappropriate examination he rubbed her breast. She said the doctor went looking f...

Cooling Temperatures Help Crucian Carp

...n oxygen runs out. Water temperature, not oxygen, acts as trip The researchers spent 12 months gathering 20-30 carp each month from a fish trap they set in a nearby pond. They began the experiment in May 2002 and finished in June 2003, tracking water temperature and examining the brains of the fish short...

Elusive Step In DNA Mutation Uncovered By Researchers

...he phosphate is crucial to the reaction because it acts as a sink that holds one of the reaction products, (H3O+) together with the other product (the guanine base with an attached OH- at the C8 location). According to quantum simulations, the energy barrier leading to formation of the transition state co...

Gene variants hold clues about vulnerability to cardiovascular disease

"As science progresses in this field, we are compiling a portfolio of genes that contribute to cardiovascular disease," Gregory said. The hope, according...

Usage Of A Condom By A Teenager Varies With Their Perception Of Partners

...tner. Interestingly, the number of unprotected sex acts in the past ninety days was substantial and equivalent between the main and casual partner groups (19.2 versus 21.5, respectively). "We can conclude that, given these high rates of unprotected sex, teens in both groups may be at risk for contractin...

Brain Regulation Present Even In Spineless Creatures

...s clues as to how the far more complex human brain acts to alter behaviors, he said. One of the goals of his research at the Institute of Neuroscience at the University of Oregon is to understand the intricacies of brain signaling that allow people, such as athletes, to repeat and adjust tasks they perfor...

Chantix: Disenchanting Smokers from Nicotine

...ed the new anti-smoking drug called Chantix, which acts by imitating the effect of nicotine on the body//. Research on the effects of this drug on its users showed that almost half of the users were able to completely quit smoking, which has prompted the European regulators to consider its use in United ...

Experimental Drug Deals Effectively with Prostate Cancer Cells

An experimental RNA-based drug acts by using genetic material called targeting RNA, to enter cancer cells, and another type, called silencing RNA// , to stop the expression of a protein that keeps the cells alive, thereby destroying prostate cancer cells leaving normal cells unharmed. ...
