| sexuality and women's rights in armed conflict in sri lanka. | the discourse of human rights in armed conflict situations is well adapted to respond to violence and violation, invoking internationally agreed principles of civil and political rights. however, in areas where the subject or domain of rights discourse is contested or controversial, human rights advocates appear less prepared to promote and defend such rights. sexuality is one such domain. this paper explores the complex sexual choices women in sri lanka have had to negotiate, particularly widow ... | 2004 | 15242213 |
| a chronology for late prehistoric madagascar. | a database has been assembled with 278 age determinations for madagascar. materials 14c dated include pretreated sediments and plant macrofossils from cores and excavations throughout the island, and bones, teeth, or eggshells of most of the extinct megafaunal taxa, including the giant lemurs, hippopotami, and ratites. additional measurements come from uranium-series dates on speleothems and thermoluminescence dating of pottery. changes documented include late pleistocene climatic events and, in ... | 2004 | 15288523 |
| characterization and evolution of major histocompatibility complex class ii genes in the aye-aye, daubentonia madagascariensis. | major histocompatibility complex genes (mhc-dqb and mhc-drb) were sequenced in seven aye-ayes (daubentonia madagascariecsis), which is an endemic and endangered species in madagascar. an aye-aye from a north-eastern population showed genetic relatedness to individuals of a north-western population and had a somewhat different repertoire from another north-eastern individual. these observations suggest that the extent of genetic variation in mhc genes is not excessively small in the aye-aye in sp ... | 2005 | 15322927 |
| socio-economic and behavioural factors affecting the prevalence of ascaris infection in a low-country tea plantation in sri lanka. | the identification of the factors that affect the prevalences of geohelminthiases should help to maximize the effectiveness of programmes for the control of these diseases. in the present study, the relationships between the prevalence and intensity of human infection with ascaris and the availability of sanitary facilities, socio-economic status and personal health habits have been explored in sri lanka. the 176 subjects, who lived on a low-country tea plantation, were aged 2-50 years (median = ... | 2004 | 15324467 |
| genetic variation in beacon influences quantitative variation in metabolic syndrome-related phenotypes. | the beacon gene (also known as ubl5) was identified as differentially expressed between lean and obese psammomys obesus, a polygenic animal model of obesity, type 2 diabetes, and dyslipidemia. the human homologue of beacon is located on chromosome 19p, a region likely to contain genes affecting metabolic syndrome-related quantitative traits as established by linkage studies. to assess whether the human beacon gene may be involved in influencing these traits, we exhaustively analyzed the complete ... | 2004 | 15331561 |

| resource allocation in public hospitals: is it effective? | the allocative inefficiency is a fundamental flaw in the public hospitals of the developing countries. the inefficiencies drain the limited public resources allotted for healthcare. sri lanka's public health system faces worsening budget constraints. the resource allocation practices of the ministry of health focus on increasing the cadre of hospital staff, consequently crowding out the investments on facility development. the purpose of the study is to assess the impact of resource allocation i ... | 2007 | 16678297 |
| genome microevolution of chikungunya viruses causing the indian ocean outbreak. | a chikungunya virus outbreak of unprecedented magnitude is currently ongoing in indian ocean territories. in réunion island, this alphavirus has already infected about one-third of the human population. the main clinical symptom of the disease is a painful and invalidating poly-arthralgia. besides the arthralgic form, 123 patients with a confirmed chikungunya infection have developed severe clinical signs, i.e., neurological signs or fulminant hepatitis. | 2006 | 16700631 |
| microsatellites reveal extensive geographical, ecological and genetic contacts between invasive and indigenous whitefly biotypes in an insular environment. | human-mediated bioinvasions provide the opportunity to study the early stages of contact between formerly allopatric, divergent populations of a species. however, when invasive and resident populations are morphologically similar, it may be very difficult to assess their distribution in the field, as well as the extent of ecological overlap and genetic exchanges between invasive and resident populations. we here illustrate the use of data obtained from a set of eight microsatellite markers toget ... | 2006 | 16709274 |
| the value of small size: loss of forest patches and ecological thresholds in southern madagascar. | many services generated by forest ecosystems provide essential support for human well-being. however, the vulnerability of these services to environmental change such as forest fragmentation are still poorly understood. we present spatial modeling of the generation of ecosystem services in a human-dominated landscape where forest habitat patches, protected by local taboos, are located in a matrix of cultivated land in southern madagascar. two ecosystem services dependent on the forest habitats w ... | 2006 | 16711035 |
| multi-character population study of the vir subtelomeric multigene superfamily of plasmodium vivax, a major human malaria parasite. | plasmodium vivax, the most widely distributed human malaria parasite, contains the subtelomeric multigene vir superfamily corresponding to circa 10% of its coding genome. in this work, we used a multi-character strategy to study the vir gene repertoire circulating in natural parasite populations obtained directly from 32 human patients from endemic regions of brazil and sri lanka. cladistic analysis confirmed the existence of vir subfamilies, which varied in size and allele polymorphisms. moreov ... | 2006 | 16730808 |
| mass fatality management following the south asian tsunami disaster: case studies in thailand, indonesia, and sri lanka. | following natural disasters, mismanagement of the dead has consequences for the psychological well-being of survivors. however, no technical guidelines currently exist for managing mass fatalities following large natural disasters. existing methods of mass fatality management are not directly transferable as they are designed for transport accidents and acts of terrorism. furthermore, no information is currently available about post-disaster management of the dead following previous large natura ... | 2006 | 16737348 |
| management of dead bodies as a component of psychosocial interventions after the tsunami: a view from sri lanka. | even if predicted, disasters may not be completely averted due to reasons beyond human control. there is always likely to be a degree of loss, human as well as material. therefore, the correct strategy is to limit the damage and minimize the harm. such damage control exercises should be mindful about the psychological costs of the disaster. identification of dead bodies and the missing, as well as providing a dignified burial, is a crucial part of the overall management of a disaster. it will al ... | 2006 | 16753662 |
| the tsunami and its aftermath in sri lanka: explorations of a buddhist perspective. | this paper discusses the tsunami disaster in sri lanka with special reference to buddhism, which is the majority religion in the island. the role of religious beliefs and of religion in general in strengthening coping skills is well known. buddhism, with its specific views on the human condition and its use of psychological strategies, is almost unique among world religions. the buddhist responses to the tsunami have been discussed widely, if largely informally, in sri lanka, and many concepts a ... | 2006 | 16753667 |
| two new cytotoxic naphthoquinones from mendoncia cowanii from the rainforest of madagascar. | bioassay-guided fractionation of the root and stem extracts of mendoncia cowanii led to the isolation of two new and two known naphthoquinones. the structures of the new compounds, avicequinones d and e (1 and 2), were determined using 1d and 2d nmr spectroscopy and by chemical conversion of compound 1 to 2. the new compounds were active in the a2780 human ovarian cancer cell line with ic50 values of 7.4 - 50 microm, respectively, and 1, 3, and 4 were subsequently found to be weakly active in an ... | 2006 | 16773542 |
| biomineralogy of human urinary calculi (kidney stones) from some geographic regions of sri lanka. | kidney stones (urinary calculi) have become a global scourge since it has been recognized as one of the most painful medical problems. primary causative factors for the formation of these stones are not clearly understood, though they are suspected to have a direct relationship to the composition of urine, which is mainly governed by diet and drinking water. sixty nine urinary calculi samples which were collected from stone removal surgeries were analyzed chemically for their na, k, ca, mg, cu, ... | 2006 | 16791711 |
| benchmark concentrations for methyl mercury obtained from the 9-year follow-up of the seychelles child development study. | methyl mercury (mehg) is highly toxic to the developing nervous system. human exposure is mainly from fish consumption since small amounts are present in all fish. findings of developmental neurotoxicity following high-level prenatal exposure to mehg raised the question of whether children whose mothers consumed fish contaminated with background levels during pregnancy are at an increased risk of impaired neurological function. benchmark doses determined from studies in new zealand, and the faro ... | 2006 | 16806480 |
| moderate transmission but high prevalence of malaria in madagascar. | malaria transmission remains poorly documented in areas of low transmission. a study has been carried out over two consecutive years in analamiranga, a village located at an altitude of 885m on the western edge of the malagasy highlands, with the aim of generating and updating malariometric indexes for both mosquitoes and schoolchildren. in this village, no vector control measures were performed during the study period nor during previous decades. mosquitoes were collected monthly when landing o ... | 2006 | 16842796 |
| population differences of two coding snps in pigmentation-related genes slc24a5 and slc45a2. | the two genes slc24a5 and slc45a2 were recently identified as major determinants of pigmentation in humans and in other vertebrates. the allele p.a111t in the former gene and the allele p.l374f in the latter gene are both nearly fixed in light-skinned europeans, and can therefore be considered ancestry informative marker (aims). aims are becoming useful for forensic identification of the phenotype from a dna profile sampled, for example, from a crime scene. here, we generate new allelic data for ... | 2007 | 16847698 |
| epidemiological trends for human plague in madagascar during the second half of the 20th century: a survey of 20,900 notified cases. | to describe the principal characteristics and epidemiological trends for human plague in modern times based on the largest reported series of cases from the highly active malagasy focus. | 2006 | 16903886 |
| impact of human activity on the distribution of native and non-native cockroach species (dictyoptera) in la réunion and mayotte. | establishment of non-native species and human-driven alteration of habitats are major causes of the decline of native faunas. interference between native and non-native cockroach species was evaluated here by comparing their distribution areas in two oceanic islands: mayotte and la réunion. a factorial correspondence analysis showed that their presence is related to environmental parameters among which human activity, humidity and altitude are the three most important. human activity and humidit ... | 2006 | 16923208 |
| climate change in the seychelles: implications for water and coral reefs. | the seychelles is a small island state in the western indian ocean that is vulnerable to the effects of climate change. this vulnerability led the intergovernmental panel on climate change (ipcc) in 2001 to express concern over the potential economic and social consequences that may be faced by small island states. small island states should be prepared to adapt to such changes, especially in view of their dependence on natural resources, such as water and coral reefs, to meet basic human welfar ... | 2006 | 16944643 |
| anti-proliferative effect of euphorbia stenoclada in human airway smooth muscle cells in culture. | the ethanolic extract of a malagasy species euphorbia stenoclada (es) (euphorbiaceae), traditionally used as a herbal remedy against asthma and acute bronchitis, was tested to evaluate possible anti-proliferative activity on human airway smooth muscle cells (hasmc). the es ethanolic extract totally abolished the interleukin-1beta (il-1beta) induced proliferation of hasmc (ic(50)=0.73+/-0.08 microg/ml). no cytotoxic effect was observed up to 20 microg/ml. a bioassay-guided fractionation of the et ... | 2007 | 16971077 |
