14 strains of Getah virus were isolated from a variety of mosquito species collected in Sarawak between October 1968 and February 1970. Ten strains were isolated from C. tritaeniorhynchus 7 of them at K. Tijirak. Single strains were isolated from C. gelidus, C. pseudovishnui, M. bonneae/dives and Aanopheles species. 6 of the isolates were obtained in(More)
BACKGROUND AND AIMS OF THE STUDY The prosthetic ring annuloplasty and incompletely encircling suture techniques are effective methods of tricuspid valve repair when the problem is only annular dilatation, but not when organic tricuspid valve disease is present. A surgical technique of valve repair has been developed that is equally effective in correcting(More)
To transfer a large amount of Ca2+ to the fetus, the basal (fetal-facing) plasma membrane (BPM) of human placenta must be equipped with various extrusion mechanisms. We studied one such mechanism, Na+/Ca2+ exchange, as well as related membrane potential effects and binding properties of the two membranes. Na+/Ca2+ exchange was present in BPM and absent in(More)
BACKGROUND In patients with absent pulmonary valve syndrome, the relief of the pulmonary regurgitation at the time of primary repair improves both the early and late results. Though homograft and heterograft valves and conduits have been used for this purpose, both are not easily available and are known for late failure. Monocusp and bicuspid semilunar(More)
449 human sera collected in a Land Dyak village were tested for antibodies to 11 arboviruses. Japanese encephalitis and dengue virus antibodies were particularly prevalent. The rates of infection with these viruses were estimated to be 5-2% per annum for Japanese encephalitis, 8-8% for dengue 1 and 4-3% for dengue 2. Chikungunya virus antibodies were quite(More)
Cutaneous melanoma of the eyelid is a rare entity. We present a 53-year-old male who had a nevus on the left upper eyelid skin since childhood, which transformed into a huge ulcerated hanging mass in the same region. Excision of the mass was done and histopathology confirmed the diagnosis of nodular malignant melanoma. A small preauricular lymph node showed(More)
Calcium entry across the microvillous membrane of the human placental syncytiotrophoblast is the first step in the transfer of this important nutrient to the fetus. Calcium uptake by isolated microvillous membranes was time dependent. Equilibrium uptake was very much greater than could be explained by equilibration of the vesicle space with medium,(More)
