Noise-induced hearing loss among manufacturing factory workers in Kuching, Sarawak: Prevalence and associated risk factors.

Introduction: Noise-induced hearing loss (NIHL) is a common problem worldwide. Increased globalisation, as well as industrialisation, gives rise to an increase in the incidence of NIHL worldwide. Malaysia is not spared from this problem, either.

trehalase enzyme induced morphological and protein alterations on cyst and molecular docking studies.

The cytotoxicity of is yet to fully illustrate due to recalcitrant of during cyst stage. The formation of the trehalose layer at the cyst stage protects the inner components of this opportunist protozoan parasite. Trehalase from the (AnTre) activity on the cyst of was determined based on AnTre dose-response, morphological and protein changes.

The prevalence of anatomical variations in osteomeatal unit in patients with chronic rhinosinusitis.

Introduction: The complexities of the anatomy of the nose and paranasal sinuses, as well as its variations may create technical difficulties during surgery. The significance of these anatomical variations in pathogenesis of rhinosinusitis, which is the commonest disease in the region, is still unclear.

Objective: The aims of the study were to study the anatomical variations in the osteomeatal complex in chronic rhinosinusitis (CRS) patients and to compare them with the normal population.

Multispecies impingement in a tropical power plant, Straits of Malacca.

Marine organisms comprised about 70% of the total impinged materials by weight at water intake screens in the Kapar Power Station (KPS), Malaysia. The general groupings of 'fish', 'shrimp', 'crab', 'cephalopod' and 'others' contributed 26% (87 species), 65% (29), 2% (17), 2% (3) and 5% (42) of the total number of impinged organisms, respectively. In general, higher impingement occurred during spring tide, at nighttime and in shallow water.

Antigenic cell associated dengue 2 virus proteins detected in vitro using dengue fever patients sera.

At least three major antigenic dengue 2 virus proteins were recognized by pooled dengue fever patients' sera in infected Aedes albopictus (C6/36) mosquito cells. Dengue virus envelope (E), premembrane (PrM) and non-structural protein 1 (NS 1) dimer were detected beginning on day 3 postinfection in both the cell membrane and cytosolic fractions. Using the patients' sera, the presence of antigenic intermediate core protein (C)-PrM and NS1-non-structural protein 2a (NS2a) in the cytoplasmic fraction of dengue 2 virus infected cells was revealed.
