The core–shell morphology of graphene oxide (GO) coated Au-TiO2 (Au-TiO2@GO) nanocatalysts hasdisplayed enhanced photocatalytic activity for hydrogen production from water. The structuralmorphology of Au-TiO2@GO revealed a thin layer ( 2.5 nm) of GO shell over Au-TiO2 core, possessinghigher specific surface area ( 100 m2 g 1). Raman spectroscopy revealed bands at 1593 cm 1 and1317 cm 1 corresponding to G and D lines. GO facilitates decreases in the rate of e /h+ recombinationdue to its reduction potential and Au loading increase sensitization of TiO2 in the visible light resulting inthe increased activity for H2 production ( 114 mmol) from the water.

Introduction: Breast cancer is the most common malignancy of women in Kashmir. This study was conducted with the objective of assessing hormone receptor positivity and its correlation with age at diagnosis, tumor size, histological grade and lymph node metastasis. Materials and Methods: 132 newly diagnosed cases of invasive breast cancer diagnosed at the Department of Pathology, SKIMS, Srinagar, J&K, were included after excluding biopsies, in-situ lesions and recurrence cases. Results: Mean age of the patients was 48.2 years, 59.1% being ${\leq}50$ years of age. Mean duration of symptoms was 6.32 months. Most lesions (65.1%) were 2-5 cm and 16.7% were ${\geq}5.0$ cm in greatest dimension. The predominant (80.3%) morphology was IDC-NOS. The majority of the cases presented as grade II (52.1%) lesions and lymph node involvement was present in 65.2%. ER and PR were positive in 66.3% and 63.4% cases, respectively, increasing with rising age. High grade lesions and larger size tumors were more likely to be ER and PR negative. No correlation was found between ER/PR status and lymph node metastasis. Conclusions: ER and PR expression in breast cancers in the current study was found to be higher than studies done in India/Asia but lower than studies conducted in the West, even on Indian/Asian immigrants. Markedly lower receptor expression in Indian/Asian studies is likely due to preanalytic variables, thresholds for positivity, and interpretation criteria. American Society of Clinical Oncology/College of American Pathologists Guideline Recommendations for Immunohistochemical Testing of Estrogen and Progesterone Receptors in Breast Cancer are strongly advocated for standardization of receptor evaluation and for clinical management of breast cancer patients to provide best therapeutic options.

SOME GENERALIZED BOUNDS ON RELATIVE ENTROPIES
M.A.K. Baig,Rayees Ahmad Dar 한국산업응용수학회 2006 Journal of the Korean Society for Industrial and A Vol.10 No.2-1
Divergence measures and information inequalities are well known in the literature of information theory. In this paper we proposed some generalized bounds on Csiszar's f-divergence in terms of relative J-divergence of type s. The bounds in terms well known divergence measures such as relative J-divergence, Chi-square divergence and triangular discrimination becomes the particular cases of our proposed bounds.

Maternal health improvement is one of the main targets of India's national health programs; however, maternal mortality reduction has not yet reached satisfactory levels. Maternal health outcomes depend on the health literacy of pregnant women. The exploration of areas in which women seek information can help in a better understanding of their health information needs. A cross-sectional study assessed health information-seeking behavior during pregnancy, health information resources used, and related barriers perceived by rural women in North India. Rural women who were pregnant or had a live birth in the past six months (N=100) were selected using purposive sampling techniques from five selected villages in the Patiala district of Punjab state, India. The majority were aged 26–30 years and reported dependence on their husbands and family members in choosing sources of health information. They reported doctors, nurses, and the Internet as valuable resources for seeking health information during pregnancy. The essential topics on which women seek information are fetal growth, delivery setting, body changes during pregnancy, and other related concerns. Women reported the significant barriers to important health information as long queues and inconvenient service hours during antenatal check-ups in health settings. The findings of the study point toward the need for strengthening and improving the existing services for availability of verified and reliable information, education and communication (IEC) resources, and maternal services in the public health sector.
