China has been carrying out large-scale schistosomiasis control since the mid-1950s, but in the early 1990s, schistosomiasis was still endemic in eight provinces. A World Bank Loan Project enabled further significant progress to be made during the period 1992-2001. The control strategy was focused on the large-scale use of chemotherapy -- primarily to reinforce morbidity control -- while at the...

A total of 157 stool samples were examined for Group A rotaviruses in diarrheic children admitted to 8 different major hospitals in Malaysia. The overall incidence rate in this study was 19.7% (31 of 157) with a variation of 9.5% to 39.1% in different locations. Majority of the infections detected were in those under 2 years of age and there were fewer admissions in the older age group. The sto...

In the year 2001, 1459 Tuberculosis (TB) cases (43.1/100,000 population) were notified in Selangor. The highest age specific incidence rate was among those aged above 60 years and foreigners accounted for 15% of the cases notified. Fifteen percent of the TB cases were treated in the private sector where treatment efficacy and compliance could not be evaluated. Co- infection of Human Immunodefic...

Trivers & Willard (TW) hypothesized that evolution would favour deviations from the population sex ratio in response to parental condition: parents in good condition would have more sons and parents in poor condition would have more daughters. We analyse the universe of US linked births and infant deaths to white mothers 1983-2001, covering 48 million births and 310,000 deaths. We find that (i)...

Outer space has been a favourite theme of science fiction literature for a long time, with Stanley Kubrick's movie, 2001: A Space Odyssey (1968) being a climax in this regard. People are also interested by inner space. In Fantastic Voyage (Richard Fleischer, 1966), miniature submarines allow a medical team to adventure into the familiar and mysterious universe of the human body. In a certain wa...

Modern and Cenozoic deep-sea hydrothermal-vent and methane-seep communities are dominated by large tubeworms, bivalves and gastropods. In contrast, many Early Cretaceous seep communities were dominated by the largest Mesozoic rhynchonellid brachiopod, the dimerelloid Peregrinella, the paleoecologic and evolutionary traits of which are still poorly understood. We investigated the nature of Pereg...
