Natural medication shown to not always be a safe alternative to synthetic medication

The common perception that if medication is natural then it must be safe has recently come under fire from a researh by a Consumer Reports magazine. The consumer publication found a dozen herbal supplements, some banned in Asia, Europe and Canada but widely available in the United States, may cause cancer, kidney or liver damage and even death.

DNA free radical damage research

Certain prostate cancer cell lines are unable to repair DNA damage caused by "free radicals," according to scientists at the National Institute of Standards and Technology (NIST) and National Institutes of Health (NIH). This type of damage has been implicated before in the development of prostate cancer, but the new research provides the first solid evidence that the normal repair process is altered in prostate cancer cells, possibly leading to a cascade of events that culminate in further DNA damage and cellular dysfunction.

New process to extract proteins from membranes by using chemicals

Proteins are complex compounds that are essential for the growth and repair of tissue. While scientists understand much about the structure and stability of water-soluble proteins that ‘float’ around in humans, they know very little about the shape and stability of proteins that are embedded, or folded, into the lipid membrane of cells. Such membrane proteins make up about 30 percent of all proteins in the body.

New microgel could potentially recover any enzyme and save manufacturers considerable money

Carnegie Mellon University scientists have employed biological molecules to create a microgel that could recover costly enzymes for repeated use in catalyzing commercially important reactions. The microgel could potentially recover any enzyme and theoretically save manufacturers considerable money.

Molecular analyses of leukemia patients suggest strategies for better treatments

The cure rate for pediatric acute lymphoblastic leukemia (ALL) might continue to rise with improved use of conventional therapies. But even more effective and less toxic therapies based on genetic and pharmacogenetic studies might one day push the success rate close to 100 percent, according to an article published by investigators at St. Jude Children’s Research Hospital in the April 8 issue of the New England Journal of Medicine.

Completion of the sequencing of human chromosome 19

The United States Department of Energy (DOE) Joint Genome Institute (JGI) and Stanford University report today the completion of the sequencing of human chromosome 19, the most gene-rich of all the human chromosomes. This achievement is described in the April 1, 2004 edition of the journal Nature.

Fluorescent molecule used to examine real time chemical reactions that result in smooth-muscle contraction

Smooth muscle, found in the walls of blood vessels and in internal organs such as lungs, stomach and the bladder, contracts as the end result of a series of chemical reactions. In a new study, UT Southwestern researchers report that one set of chemical reactions resulting in the contraction of the smooth-muscle cells is augmented by a second chemical pathway that kicks in when the first pathway is limited.

Fatty acid pathway, glucose produce triacetic acid lactone

Scientists at the University of Illinois at Urbana-Champaign have designed a potential roadmap to use a biosynthetic pathway taken from a common microorganism to produce compounds that could serve as precursors to explosives or components in everyday devices such as liquid crystal displays or anti-cancer agents.

How rat's genetic blueprint stacks up against those of mice and humans

An international research team, supported by the National Institutes of Health (NIH), today announced it has completed a high-quality, draft sequence of the genome of the laboratory rat, and has used that data to explore how the rat's genetic blueprint stacks up against those of mice and humans.

Research team has found a new way to streamline gene isolation to determine their functions

A single strand of plant or animal DNA may contain tens of thousands of genes, each programmed to produce a specific protein essential for the growth or survival of the organism. The challenge for geneticists is to isolate individual genes and determine their function -- a painstaking process often requiring years of laboratory trial and error.

Drug, Nembutal can suppress activity in colon cancer cells

A barbiturate once commonly used to treat anxiety may play a role in controlling the spread of colon cancer, say researchers from The University of Texas M. D. Anderson Cancer Center.

Three of the world’s top women chemists visit UK to inspire young scientists

Three of the world’s top women chemists are visiting the UK this week (29 March - 2 April) to tour institutions and talk about their research with the aim of inspiring young scientists to emulate their achievements. The inaugural Rosalind Franklin International Lectureship Programme has been masterminded by Professor Susan Gibson, Imperial College London, who funded the initiative with her prize money from the Royal Society Rosalind Franklin Award.

A common antibiotic used to treat arthritis and acne shows promise for limiting the severity of spinal cord and brain injuries

When a fall, car crash, bullet, or knife crushes or cuts a spinal cord, the injury does not stop there. Rather, tissues continue to discharge toxic chemicals for hours, even days and weeks. These chemicals kill and disable nerve cells some distance away from the core injury, compounding the damage and making rehabilitation more difficult or impossible.

Breakthrough studies that could lead to a new means of combating malaria

EMBL scientists have identified four mosquito proteins that affect the ability of the malaria parasite (Plasmodium) to survive and develop in the malaria-carrier mosquito (Anopheles). This breakthrough could be used to block the transmission of malaria from mosquitoes to humans.

Carbon Dioxide may be used in medical implants

Carbon dioxide, an environmentally friendly solvent for dyeing and dry cleaning, may become a valuable new tool for making medical implants, according to a study at Ohio State University.

Enzyme Acetylcholinesterase (AChE), New Approach to Drug Design

French and American researchers have developed a unique approach to drug design where an important neuron-signaling enzyme called acetylcholinesterase (AChE) acts as a microscopic vessel filled with reactant chemicals, to create its own, tailored therapeutic agent.

Plasticiser Phthalates connected with rising infertility rates

Phthalates, largely used as plasticisers, have long been suspected in connection with rising infertility rates, particularly among men. These substances are quite common and are considered highly hazardous to human health because they disrupt the hormonal balance and impair reproduction and development. What has not been clear up to now is the amount of phthalates that enter the human body.

Japanese study raises concerns for childhood health issues

The number of children suffering from mental disorders and health problems such as allergies and asthma has risen sharply over the past decade in this country. The United States and European countries are also facing the increasingly serious problems of premature births and childhood obesity, in addition to allergic reactions. Many experts say the rise in health problems involving children is related to the use of chemicals in our daily lives and the impact of medical treatment provided to the children's mothers.
