BACKGROUND Pediculiasis is treated aggressively in the United States, mainly with permethrin- and pyrethrin-containing pediculicides. Increasingly frequent anecdotal reports of treatment failure suggest the emergence of insecticidal resistance by these lice. OBJECTIVE To confirm or refute the susceptibility of head lice sampled in the United States to permethrin. DESIGN Survey. Head lice we...

BACKGROUND Southeast Asian deforestation rates are among the world's highest and threaten to drive many forest-dependent species to extinction. Climate change is expected to interact with deforestation to amplify this risk. Here we examine whether regional incentives for sustainable forest management will be effective in improving threatened mammal conservation, in isolation and when combined w...

OBJECTIVE To investigate the prevalence of antenatal depression and to assess whether the common risk factors identified in previous studies were applicable to women in Sabah, Malaysia. METHODS A prospective cohort study of 2072 women was conducted in Sabah during 2009-2010. Participants were recruited at 36-38 weeks of gestation to complete a self-administered questionnaire regarding their d...

The medicinal herb, Smilax bracteata C. Presl. is a monocotyledon species in the family of Smilacaceae. There are about 261 species and 240 infraspecific species (IPNI, 2015) which are distributed in tropical and subtropical regions, with some herbaceous species extending their range into the temperate regions of North America, Europe and Asia. The greatest diversity is found in eastern Asia. I...

Understanding the socio-economic factors that are associated with fishers‘ willingness to delay gratification may be useful for designing appropriate fisheries management and conservation policies. We aim to identify the predictors of low discounting behaviour among fishers, which is analogous to having a longer-term outlook. We base our empirical study on two small-scale tropical reef fisherie...

Two new species of Ancyronyx Erichson, 1847 (Coleoptera: Elmidae) are described from Borneo: A. pulcherrimus (Brunei) and A. reticulatus (Sabah). Habitus views, illustrations of important characters as well as plastron structures of Ancyronyx reticulatus are presented and discussed.

Great apes are threatened with extinction, but precise information about the distribution and size of most populations is currently lacking. We conducted orangutan nest counts in the Malaysian state of Sabah (North Borneo), using a combination of ground and helicopter surveys, and provided a way to estimate the current distribution and size of the populations living throughout the entire state....

Lymphomas, ranked twelve among all cancers world-wide in the 1990s, in which it is more prevalent in males compared to females. A previous study on lymphomas in East Malaysia for a period of 3 years from 1981-1983 showed that the pattern of lymphomas conformed to the general pattern observed in Asia. Current study reviews lymphoma cases from the Department of Pathology, Queen Elizabeth Hospital...

Sabah, situated in one of the world's biodiversity hotspots, has the largest number of islands in Malaysia with more than 500 of various sizes and degrees of isolation. However, information on the islands' biodiversity is limited. This study provides an up-to-date checklist of land snail species found on 24 west coast islands in Sabah. A total of 67 species (nearly 20% of the total number of la...
