Mini-microscope For Low-cost Diagnostics Created From Stripped Mobile Phone Camera
2013-12-06 12:34:40

University of Helsinki Microscopy, being relatively easy to perform at low cost, is the universal diagnostic method for detection of most globally important parasitic infections. Methods developed in well-equipped laboratories are, however, difficult to maintain at the basic levels of the health care system due to lack of adequately trained personnel and resources. Researchers at the Institute for Molecular Medicine Finland, FIMM, University of Helsinki and Karolinska Institutet,...

How Mosquitoes Smell Us
2013-12-05 14:31:24

Brett Smith for redOrbit.com - Your Universe Online Many a pleasant summer’s evening has been ruined by the onset of swarms of mosquitoes, and studies have shown that the flying pests are drawn to both the carbon dioxide we exhale and the scent of our skin. A new study, published in the journal Cell, has found that mosquitoes actually use the same olfactory mechanism to detect both carbon dioxide and skin odors. "It was a real surprise when we found that the mosquito's CO2 receptor...

Report provides real and estimated costs of repurposing drugs and new chemical entities, evoking the lessons learned based on alternative pathways and partnerships Today, at a scientific meeting at Institut Pasteur, France, entitled ‘Best Science for the Most Neglected: Where Do We Stand Ten Years On?’, co-organized with Institut Pasteur and MSF and in collaboration with PLOS, the Drugs for Neglected Diseases initiative (DNDi) marks its 10-year anniversary by issuing a report that...

An analysis of patients from across the malaria endemic world suggests that a key antimalarial treatment could be improved by better dosing in young children Antimalarial drug resistance has hampered malaria control programs for almost 60 years. A key factor in combatting this threat is to ensure that all antimalarial drugs are deployed in a way that ensures that the maximum number of patients are completely cured. A study published this week in PLOS Medicine explores this issue by...

Lawrence LeBlond for redOrbit.com - Your Universe Online Sudan’s Federal Ministry of Health (FMOH) has notified the World Health Organization (WHO) of an outbreak of yellow fever that is affecting 12 localities in West and South Kordofan states. A total of 44 suspected cases and 14 deaths have been reported from October 3 to November 24, 2013 in the localities of Lagawa, Kailak, Muglad and Abyei in West Kordofan and Elreef Alshargi, Abu Gibaiha, Ghadir, Habila, Kadugli, Altadamon,...

An international group of scientists led by Tim Anderson Ph.D., at the Texas Biomedical Research Institute and Philip LoVerde Ph.D., at the University of Texas Health Science Center at San Antonio has identified the mutations that result in drug resistance in a parasite infecting 187 million people in South America, Africa and Asia. The new finding allows detailed understanding of the drugs' mechanism of action and raises prospects of improved therapies. "This is a major advance," said...

The world market for infectious disease tests is estimated at $14.5 billion in 2012 and should grow at a slightly higher rate than the rest of the diagnostics market. The finding was made in Kalorama Information’s new report, The “World Market for Infectious Disease Diagnostic Tests.” New York, NY (PRWEB) November 18, 2013 Increasing incidence of infectious disease is expected to make the market for infectious disease tests among the most dynamic in the in vitro diagnostics...

First placebo-controlled study in adults with Chagas disease highlights urgent need to scale up treatment for millions of patients at risk According to results of the first-ever Phase 2 clinical trial in Bolivia, conducted by the Drugs for Neglected Diseases initiative (DNDi), the experimental drug candidate E1224 showed good safety and was effective at clearing the parasite that causes Chagas disease, but had little to no sustained efficacy one year after treatment as a single medication....

Mystery Surrounds Isolated Dengue Fever Outbreaks In United States
2013-11-15 09:03:40

Lawrence LeBlond for redOrbit.com - Your Universe Online Dengue fever, an infectious tropical disease carried by several species of mosquito in the genus Aedes, has been showing up in Key West and the Florida mainland, potentially exposing millions of people to a disease that can lead to life-threatening illness. While the dengue virus is mysteriously working its way up into Florida, researchers are equally as puzzled as to why the dangerous illness has not yet become common in and...

Lower doses of the antimalarial drug primaquine are as effective as higher doses in reducing malaria transmission, according to a study published today in Lancet Infectious Diseases by London School of Hygiene & Tropical Medicine researchers. Primaquine is one of the few antimalarial drugs that targets the transmission stages of the malaria parasite, the gametocytes, and is therefore considered to be an important tool for malaria elimination. However, standard doses of the drug...

Yellow fever is an acute viral hemorrhagic disease with a 40 to 50 nm enveloped RNA virus with positive sense of the Flaviviridae family. It is transmitted by the bite of female mosquitoes and is found in tropical and subtropical areas in South America and Africa, but not in Asia. Primates and a few kinds of mosquitoes are the only known hosts. The origin of the disease is most likely Africa. From there it was introduced to South America through the slave trade in the 16th century. There...

West Nile virus (WNV) is a virus of the family Flaviviridae. It is part of the Japanese encephalitis antigenic complex of viruses and is found in both tropical and temperate regions. It primarily infects birds but can infect humans, horses, dogs, cats, bats, and other mammals. Humans are generally infected through the bites of mosquitoes and about 90% of West Nile Virus infections are without symptoms. The virion is 45-60 nm and covered with a relatively smooth protein surface. It is...

Marburg virus, or Marburg, is the standard name for the genus of viruses Marburgvirus which contains the species, Lake Victoria Marburgvirus. It causes Marburg Hemorrhagic Fever (MHF) which originated with primates. It originated in Africa and can infect humans and primates. It is in the same taxonomic family as Ebola and both are identical structurally although they elicit different antibodies. It was named after the location of the first outbreak in Marburg, Germany in 1967. The...

Lassa fever, first described in 1969 in Lassa, is an acute viral hemorrhagic fever. Clinical cases were known a decade before this but were not associated with this viral pathogen. It is endemic in West African countries and causes approximately 5,000 deaths. The Natal Multimammate Mouse is the primary animal host. The rodent is a source of protein but the virus is usually transmitted by the contact with the feces and urine of animals accessing grain stores in residences. The lassa virus...

Dengue fever and dengue hemorrhagic fever (DHF), caused by the dengue virus, is among the spectrum of acute febrile tropical disease and is transmitted by mosquitoes. Occurring mainly in the tropics it can be life threatening and is caused by four closely related virus stereotypes of the genus Flavivirus. It was identified and named in 1779. It has a nickname of "breakbone fever" due to it causing sever generalized bodyache. It tends to be more prevalent in the urban districts of its range...
