However, his views on vitamin A deficiency cannot be allowed to pass unchallenged. That the status of Bitot's spot is st...

This cross-sectional study was performed to determine ocular findings in renal transplant recipients and to correlate them with certain clinical characteristics related to transplantation. The study was performed on 150 patients who had received a renal transplant at least three months earlier and had serum creatinine levels < 3 mg/dL. All patients underwent a complete ophthalmologic examinatio...

Background: Objective of the study was to evaluate conjunctival ultraviolet autofluorescence (CUVAF) device, as an indicator ocular (UV) radiation exposure in pterygium and pinguecula among outdoor workers.Methods: Subjects above 21 years age engaged work were enrolled based on inclusion criteria. A standardized questionnaire administered assess lifetime UV erythemal dose noted from tropospheric...

The genus Pinguicula is one of the three genera of the carnivorous Lentibulariaceae, comprising approximately 80 species. Phylogeny inference using nucleotide sequences of the chloroplast gene matK and the trnK group II intron, as well as a set of 32 morphological characters revealed five well-supported, major lineages within the genus. These lineages largely reflect radiations in clearly defin...

Several important fitness components in herbaceous perennial plants are commonly related to plant size: flowering probability, reproductive allocation and fecundity. However, evidence for such size-dependence of fitness components is mostly anecdotal and unconnected to other life history traits. Here we report size-dependence for flowering probability and reproductive allocation in 11 populatio...
