UCR Today: Cell Biologist to Begin Work on Discovering Structure of Malaria Parasite Genome

The University of California, Riverside and the University of Washington have received a four-year grant of more than $2 million from the National Institutes of Health to discover this 3-D structure of Plasmodium’s genome during the parasite’s erythrocytic cycle that is responsible for disease in humans.

The erythrocytic cycle that the researchers will study is a 48-hour cycle that can repeat for several days or weeks in humans.

Karine Le Roch, an associate professor of cell biology and neuroscience, is the principal investigator of the grant

Chikungunya Mosquito Virus Fears In North Queensland

Health authorities fear a dengue-like mosquito-borne virus could spread through far north Queensland following a massive outbreak in Papua New Guinea.

Since the start of the year, 11 people in Queensland have been diagnosed with chikungunya, which causes fever, rashes and prolonged joint pain.

Ten of the people contracted the virus in PNG where more than 3000 people have been hit by the virus.

Another person was bitten by a mosquito in Indonesia before flying to Queensland.

The majority of the 11 affected are Australian citizens but almost half of them live outside far north Queensland.

Tropical Public Health Services director Dr Richard Gair says the PNG outbreak is recent and could lead to an outbreak in far north Queensland.

allAfrica.com: Africa: New Malaria Tool to Help Track Insecticide Resistance

The tool, the IR Mapper, “consolidates reports of insecticide resistance in malaria vectors onto filterable maps to inform vector-control strategies”. Data consolidation for the programme was conducted by the Swiss company Vestergaard Frandsen and a partnership between the Kenya Medical Research Institute and the US Centers for Disease Control and Prevention KEMRI/CDC. The map interface was developed by ESRI Eastern Africa.The system, which was launched in April, allows users to view new data from tests on insecticide susceptibility and resistance mechanisms, and to retrieve existing published data, including historic information from as far back as 1952. These data can be used to generate tailored maps from 51 countries.

Silver makes antibiotics thousands of times more effective : Nature News & Comment

Before adding silver to antibiotics, “we’ll have to address the toxicity very carefully”, says Fowler. Ingesting too much silver can also cause argyria, a condition in which the skin turns a blue-grey colour — and the effect is permanent.

Collins says that he and his colleagues saw good results in mice using non-toxic amounts of silver. But, he adds, there are ways to reduce the risk even further. “We’re also encouraging people to look at what features of silver caused the helpful effects, so they can look for non-toxic versions,” he says.

Fighting the dreaded dengue – Manila Standard Today

Despite the yearly preparations against Dengue, the number of individuals afflicted continues to increase. According to the Dengue Surveillance Report of the Department of Health (DOH)-National Epidemiology Center, from January 1 to August 18 last year, a total of 80,745 cases of Dengue has been recorded, about 14.14 percent higher compared to the same period in the previous year, which was 70,745 cases.

The NEC also said the number of dengue patients who perished also rose from 424 last year to 496. The department said the mostly victimizes children, aged 1 to 10, and teenagers.

Enrique R. Alberto, executive vice president and chief operating officer of Philippine Life Financial Assurance Corp., explained that while preventive measures are important in eradicating Dengue, many people still die from Dengue due to the lack or even absence of immediate medical given to those infected.
