Accumulation patterns of anthocyanin and γ-oryzanol during black rice grain development.

Pigmented rice, especially black rice, is gaining popularity as it is rich in antioxidants such as anthocyanins and γ-oryzanol. At present, knowledge about temporal control of biosynthesis and accumulation of antioxidants during grain development is limited. To address this, the accumulation patterns of anthocyanins and γ-oryzanol were assessed in two distinct black rice genotypes over the course of grain development, and the expression of known regulatory genes for anthocyanin biosynthesis was examined. The results indicated that total γ-oryzanol content increased continuously throughout grain development, while total anthocyanins peaked at dough stage (15 to 21 days after flowering) followed by a decline until grain maturity in both genotypes. However, the rate of decrease in anthocyanin content differed between genotypes, and a more prominent decline in cyanidin 3-O-glucoside (C3G) relative to peonidin 3-O-glucoside (P3G) was observed for both. Anthocyanin content was closely linked with the expression of key regulatory genes in the MBW (MYB-bHLH-WD40) complex. This improved knowledge of the genotype-specific biosynthesis (anthocyanins only) and accumulation patterns of anthocyanins and γ-oryzanol can inform subsequent research efforts to increase concentrations of these key antioxidants in black rice grains.

Effect of wheat species (Triticum aestivum vs T. spelta), farming system (organic vs conventional) and flour type (wholegrain vs white) on composition of wheat flour - Results of a retail survey in the UK and Germany - 2. Antioxidant activity, and phenolic and mineral content.

There is strong evidence for health benefits from whole-grain wheat consumption and these have been linked to their higher fibre, antioxidant/(poly)phenolic and mineral contents. However, there is still scientific controversy about the relative effect of wheat species (Triticum aestivum vs T. spelta) and production methods (conventional vs organic) on the nutritional composition of wheat. The retail survey reported here showed that, the use of spelt varieties and organic production results in significantly higher (between 10 and 64%) levels of phenolics and some minerals in wheat flour. However, the relative effect of removing the outer bran and germ during milling was substantially larger; levels of antioxidant activity, and many phenolic compounds and mineral nutrients were 2-5 times higher in whole-grain than white flour. Organic flour contained higher concentrations of the undesirable metals Al and Ni (12% and 81% respectively), and spelt flour had 28% higher concentrations of the toxic metal Cd.

Effect of Topical Steroid-Dependent Facial Dermatitis on Quality of Life: A Hospital-Based Cross-Sectional Study Using DLQI.

BACKGROUND: The rampant, disturbing, and dismal unrestricted use of topical corticosteroids on face results in steroid-induced dermatitis termed topical steroid-dependent face (TSDF). It is an embarrassing and irritating condition for a patient. There is paucity of data from India regarding the effect of TSDF on the quality of life (QoL) of such patients. AIMS: The aim of this study was to study the effect of TSDF on the QoL of patients with the help of a validated, easy-to-use, and reproducible dermatology life quality index (DLQI). METHODS: A cross-sectional study was done among the outpatients seeking treatment for TSDF at a tertiary care hospital of a medical college. Patients were administered Hindi questionnaire version of DLQI. Controls were apparently healthy age- and sex-matched individuals. RESULTS: DLQI scores revealed that TSDF had some effect on QoL in 98.11% of study patients. Study group had a mean DLQI score of 11.49. Statistically significant higher DLQI scores were recorded among females, patients aged <20 years and those who had no formal education/illiterate. CONCLUSIONS: TSDF affects QoL in majority of patients and it has a very large effect on the QoL in more than one-third of the patients.

A prospective study to validate various clinical criteria used in classification of leprosy: a study from a tertiary care center in India.

BACKGROUND: Various clinical criteria are used to categorize leprosy patients into paucibacillary (PB) and multibacillary (MB), thus aiding in appropriate treatment. However, comprehensive studies validating these criteria are minimal. AIMS: To assess sensitivity and specificity of different clinical criteria individually and in combination for classifying leprosy into PB/MB spectrum. METHOD: A prospective study was conducted wherein 50 newly diagnosed, untreated leprosy cases were recruited and classified into PB and MB using the following clinical criteria: number of skin lesions (NSL), number of body areas affected (NBAA), and size of largest skin lesion (SLSL). Patients with pure neuritic leprosy, diffuse macular type of lepromatous leprosy, and with reactions were excluded. Sensitivity and specificity of these clinical criteria in classification was calculated taking histopathological findings as gold standard. RESULTS: Among 50 patients, 37 were males and 13 were females with a mean age of 32.08 ± 16.55 years. The sensitivity and specificity of NSL, NBAA, and SLSL was 94.74 and 87.1%, 94.74 and 61.29%, and 73.68 and 16.13%, respectively. Combining all three criteria, the sensitivity increased to 100%, but specificity decreased drastically to 12.9%. The ROC curve for NSL, NBAA, and SLSL showed a cutoff of ≥6 skin lesions, ≥3 body areas affected, and ≤2 cm lesion to classify as MB. CONCLUSION: The current WHO system of leprosy classification based on NSL seems to be best among available clinical criteria. Uniform and sensible application of this criteria itself assures appropriate categorizing and leprosy treatment with reasonable sensitivity and specificity.
