Itch-specific nerve cells: an interview with Associate Professor Xinzhong Dong

Itch was actually defined by a German physician more than 350 years ago. His name was Samuel Hafenreffer. He defined itch as an unpleasant sensation that makes people want to scratch. You probably think this is a very simple definition but itch is really a very complex sensory modality.

Itch-specific nerve cells in skin discovered by John Hopkins scientists

Johns Hopkins researchers have uncovered strong evidence that mice have a specific set of nerve cells that signal itch but not pain, a finding that may settle a decades-long debate about these sensations, and, if confirmed in humans, help in developing treatments for chronic itch, including itch caused by life-saving medications.

New low-cost combined therapy shows promise against malaria

Malaria brings misery and death to millions in the developing world each year, and fighting it keeps medical researchers up at night because the mosquito-borne parasite Plasmodium falciparum, which causes the deadliest form of the disease, has developed resistance to every drug thrown at it. Resistance has cut short the useful life of nearly every therapy tried so far, experts say.

Malaria vaccine trial: an interview with Professor Sir Brian Greenwood

Malaria is an infection caused by a parasite called plasmodium, which is transmitted from person to person by females of some species of mosquito. It is primarily a disease of tropical countries.

Novartis to highlight key data from extensive oncology portfolio at SABCS and ASH meeting

Novartis will highlight more than 140 presentations on key data from its extensive oncology portfolio at the leading year-end scientific meetings devoted to hematology and breast cancer, demonstrating continued innovation in research and development efforts to advance the care of patients with cancer and rare diseases.

Global health community should save AMFm because it saves lives

The Affordable Medicines Facility-malaria began as a pilot program in 2010 to "provide a 'co-payment' to the manufacturers of [artemisinin-based combination therapies (ACTs)], thereby allowing commercial wholesalers and private or government health services to purchase the drugs at a fraction of the already low negotiated price," Kenneth Arrow, a Nobel laureate in economic sciences in 1972 and an emeritus professor of economics at Stanford University, writes in a New York Times opinion piece.

Malarial drug shows promise in stopping breast cancer

A malarial drug is showing promise in stopping breast cancer before it starts, Mason researchers are discovering during a clinical trial.

Chloroquine begins to work against malaria

Malaria-drug monitoring over the past 30 years has shown that malaria parasites develop resistance to medicine, and the first signs of resistance to the newest drugs have just been observed. At the same time, resistance monitoring at the University of Copenhagen shows that the previously efficacious drug chloroquine is once again beginning to work against malaria. In time that will ensure cheaper treatment for the world's poor.

New MMV framework to evaluate risk of resistance for antimalarials

Medicines for Malaria Venture has developed a framework to evaluate the risk of resistance for the antimalarial compounds in its portfolio. A paper based on this work: A framework for assessing the risk of resistance for antimalarials in development has been published in the Malaria Journal today.

NIH awards ADi Phase II SBIR grant to scan Plasmodium falciparum proteome for protective antigens

Antigen Discovery, Inc. today announced that it has received a Phase II Small Business Innovation and Research award from the National Institute of Allergy and Infectious Diseases of the National Institutes of Health. The three-year award, totaling approximately $ 2.5 million, is a continuation of a Phase I SBIR grant to scan the Plasmodium falciparum proteome for protective antigens.

Intense war against malaria outlined by two studies in The American Journal of Tropical Medicine and Hygiene

A pair of provocative studies in the July 2012 issue of The American Journal of Tropical Medicine and Hygiene (AJTMH) provides a window into the intense ground war now underway against malaria.

Scientists may be step closer to developing new therapy for AML

Scientists at Virginia Commonwealth University Massey Cancer Center may be one step closer to developing a new therapy for acute myeloid leukemia (AML) after discovering that the targeted agents obatoclax and sorafenib kill leukemia cells much more effectively when combined than when the drugs are administered individually.

Dual prevalence of STIs/RTIs and malaria in pregnancy found among women in sub-Saharan Africa

A review of studies reporting estimates of the prevalence of sexually transmitted infections/reproductive tract infections (STIs/RTIs) and malaria over the past 20 years suggests that a considerable burden of malaria and STIs/RTIs exists among pregnant women attending antenatal (before birth) facilities in sub-Saharan Africa, according to a review and meta-analysis of previous studies published in the May 16 issue of JAMA, a theme issue on Global Health.

Researchers develop potent new drug that can kill tumor cells

All cells have the ability to recycle unwanted or damaged proteins and reuse the building blocks as food. But cancer cells have ramped up the system, called autophagy, and rely on it to escape damage in the face of chemotherapy and other treatments. Now, researchers at the Perelman School of Medicine; the Abramson Cancer Center; and the School of Arts and Sciences, at the University of Pennsylvania, have developed a potent new drug that clogs up the recycling machinery and kills tumor cells in mouse models.

Genetically modified mosquitoes offer hope of malaria eradication amid growing drug resistance

"In recent weeks, the emergence on the Thai-Myanmar border of malaria strains resistant to artemisinin, a plant-derived drug, have led to pessimistic headlines and reminders of the setback caused by resistance to the drug chloroquine, which began in the 1950s," columnist and author Matt Ridley writes in the Wall Street Journal's "Mind & Matter," noting, "April 25 is World Malaria Day, designed to draw attention to the planet's biggest infectious killer."

Study: Kidney cancer growth depends on autophagy

New research at the University of Cincinnati (UC) suggests that kidney cancer growth depends on autophagy, a complex process that can provide cells with nutrients from intracellular sources. Researchers say in certain circumstances autophagy can protect tumor cells from chemotherapy, allowing them to survive for long periods of time in a hidden, dormant, metastatic state.

Drug resistance woes hamper anti-malaria fight

Researchers have found that there is increasing resistance to the front-line treatments for malaria. A pair of studies published in The Lancet and the journal Science showed how the disease is moving fast into new territory and identified a region of the parasite's genome that may be responsible for mutating in order to survive.

'Large-scale action' needed in Myanmar to prevent spread of artemisinin-resistant malaria parasites

In this New York Times opinion piece, Frank Smithuis, director of Medical Action Myanmar in Yangon, and Nick White, professor of tropical medicine at the Mahidol Oxford Tropical Medicine Research Unit in Bangkok, recount a brief history of the development of anti-malaria drugs and their contribution to "a significant global reduction in malaria" and note that this progress "is now threatened by the emergence of malaria parasites that are resistant to artemisinin on the Cambodia-Thailand border ..., the same place where chloroquine resistance emerged 50 years ago and spread across Asia and Africa to claim millions of lives."

Researchers make significant strides in the study of Intrahepatic Cholangiocarcinoma

Researchers at the University of Rochester Medical Center's James P. Wilmot Cancer Center have made significant strides in the study of a primary cancer of the liver- Intrahepatic Cholangiocarcinoma (IHCC), also called biliary tract cancer.
