The enigmatic 'Spectacled Flowerpecker'-a probable new bird species from the island of Borneo-was first sighted in the Danum Valley of Sabah, Malaysia in 2009. However, the absence of a holotype specimen has prevented its formal scientific description. Since then only a handful of reports from widely disparate localities across the island have emerged, all from lowland sites and often in close association with fruiting mistletoe. Here, we report the long-awaited capture of a specimen of this putative new species and confirm its morphological and molecular distinctiveness as a novel species in the genus Dicaeum.
To determine pregnancy outcome in hyperemesis gravidarum and the effect of metabolic, biochemical, hematological and clinical indicators of disease severity on outcome.
In a retrospective analysis of 192 cases of presumed hyperemesis gravidarum, there were no biochemical markers that predicted hospital readmission. There was, however, statistically significant negative predictive value in abnormal liver function tests. This could represent acute self-limited illness with a component of hepatitis as the cause for the clinical presentation, rather than hyperemesis.
The association between female fetal sex and hyperemesis gravidarum is well established in European and North American populations. The association between female fetuses and severity of hyperemesis remains uncertain. A retrospective study based on case notes review of 166 Asian women hospitalised for hyperemesis was performed. Female fetuses were significantly associated with hyperemesis in our population (P= 0.004, OR 1.6, 95% CI 1.2-2.2) as well as associated with severe ketonuria and high urea. When both severe ketonuria and high urea were present at initial hospital admission for hyperemesis, 83% (95% CI 66-93) of the fetuses were female.
BACKGROUND: Rheumatoid arthritis is the commonest inflammatory joint disease, affecting nearly 1% of the adult population worldwide. Early and accurate diagnosis and prognosis of rheumatoid arthritis (RA) have become increasingly important. In the present study, we aimed to elucidate the relationships between hematological, biochemical, immunological and cytogenetic parameters in rheumatoid arthritis patients and healthy normal controls.
METHODS:The study group comprised of 126 RA patients and equal number of healthy normal control subjects. The blood wa s collected and analyzed for biochemical, immunological, enzymatic and cytogenetic parameters.
RESULTS: Results of the present study indicated that 20% of RA patient's hematological, 31% of biochemical and 70% immunological parameters had a significant difference from the controls and reference range. The RF and anti-CCP antibody levels were also positive in 70% of RA patients. A significant increase in minor chromosomal abnormalities was also observed in patients as compared to controls.
CONCLUSION: The knowledge about autoimmune diseases is very low among the South Indian population. The present study has thus helped in understanding the RA disease in a better way based on a pattern of various clinical markers of the disease condition which might help in planning therapeutic intervention strategies and create awareness about the disease management among RA patients of the population studied.

Inexpensive forms of tobacco are widely used in developing countries such as India. We have evaluated genotoxicity endpoints (chromosome aberrations, micronucleus frequency, comet assay) and polymorphisms of the XRCC1 and p53 genes among smokers and smokeless tobacco (SLT) users in rural Tamilnadu, South India. Cytogenetic, DNA damage and SNP analyses were performed on peripheral blood samples; micronucleus frequency was measured in peripheral blood and buccal mucosa exfoliated cells. Both categories of tobacco users had elevated levels of genotoxic damage. SNP analysis of tobacco users revealed that 17% carry the XRCC1 gln399gln genotype and 19% carry the p53 pro72pro genotype. Both genotypes are associated with increased risk of cancer.
