TL;DR: There was strong ELISA-based evidence implicating An.
Abstract: A study on adult anopheline ecology and malaria vector incrimination was carried out from 1986 to 1989 during irrigation development in an area of the Mahaweli Project in eastern Sri Lanka. Eleven potential vector species were collected resting indoors or by using human or bovid bait, and from light trap catches. Overall, Anopheles vagus (Donitz), An. annularis (van der Wulp), and An. subpictus (Grassi) were the most prevalent, and An. culicifacies (Giles) and An. barbirostris (van der Wulp) were the least prevalent species. The abundance of An. aconitus (Donitz), An. jamesii (Theobald), An. pallidus (Theobald), and An. subpictus increased after irrigation development, while An. annularis, An. barbirostris, An. culicifacies and An. varuna (Iyengar) decreased. Populations of An. nigerrimus (Giles), An. tessellatus (Theobald), and An. vagus did not change substantially. Seven species were infected with malaria parasites, as determined by enzyme-linked immunosorbent assays (ELISA) done on mosquito head-thorax triturates. The main species involved were An. annularis, at peak abundance during the 1986-1987 period of development leading to the onset of irrigation, and An. subpictus, during times of seasonal abundance in the post-irrigation period of 1988 to 1989. Although occurring at low abundance, An. culicifacies was involved in malaria transmission irregularly throughout the study period. While there was strong ELISA-based evidence implicating An. subpictus as a major post-irrigation vector, confirmation of its vector status must await dissection and ELISA-based evidence of P. vivax and P. falciparum sporozoite infection rates in salivary glands.

TL;DR: The authors examined the relationship between the state of necessity and entrepreneurial activity, through qualitative case studies from Uganda and Sri Lanka, and a survey of 1006 Ugandan adults, and found that those with low incomes were much less likely to start a business, because they often became "trapped" by having to work long hours for just enough income to survive.
Abstract: The paper examines the relationship between the state of necessity and entrepreneurial activity, through qualitative case studies from Uganda and Sri Lanka, and a survey of 1006 Ugandan adults. Questions are posed on the tenability of hypothesis that necessity is a primary motive for business start-up in poor countries. The relationship between necessity and business start-up, though significant, is in the opposite direction from that predicted by the "necessity hypothesis". Those with low incomes were much less likely to start a business, because they often became "trapped" by having to work long hours for just enough income to survive. Opportunistic diversification, however, flourished once resources improved. The results question recent attempts to classify countries on the basis of distinctive forms of entrepreneurship based on necessity and opportunity.

TL;DR: Children younger than 11-years-old with mandibular fractures were studied regarding age, sex, type of fracture, incidence, etiology, methods of treatment, and complications and one child had retarded facial growth due to damage of the condylar growth center.

TL;DR: The higher detection rate of urinary ochratoxins in Sri Lankans indicates that exposure to nephrotoxic mycotoxins is common in the region, while healthy Japanese individuals had lower levels than in Sri Lanka.
Abstract: This was a screening study that aimed to determine the presence of nephrotoxic mycotoxins in urine samples from patients with chronic kidney disease of uncertain etiology in the North Central Province of Sri Lanka. The percentage detection of aflatoxins, ochratoxins and fumonisins in 31 patients were 61.29%, 93.5% and 19.4%, respectively. Geometric means of urinary aflatoxins and ochratoxins were 30.93 creatinine and 34.62 ng/g creatinine in chronic kidney disease of uncertain etiology stage 1–2 patients and 84.12 ng/g creatinine and 63.52 ng/g creatinine in unaffected relatives of patients. In chronic kidney disease of uncertain etiology stage 3–5 patients, geometric means of urinary aflatoxins and ochratoxins were 10.40 and 17.08 ng/g creatinine, respectively. Non-affected relatives of patients (n = 6) had comparable levels of these mycotoxins, but healthy Japanese individuals (n = 4) had lower levels than in Sri Lanka. The higher detection rate of urinary ochratoxins in Sri Lankans indicates that exposure is common in the region.
