Strong acceptor-weak acceptor system FN-TPy has been designed and synthesized,which undergoes solvent dependent self-assembly in mixed aqueous media to generate through space intermolecular charge transfer *** as-prepared entropically favoured assemblies of FN-TPy exhibit excellent photostability and photosensitizing properties in the assembled state to activate aerial oxygen for efficient generation of reactive oxygen species through Type-I and Type-II *** FN-TPy exhibits excellent potential for regulated oxidation of alcohols and aldehydes under mild reaction conditions(visible light irradiation,aqueous media,room temperature)using aerial oxygen as the‘oxidant’.The present study demonstrates the potential of FN-TPy assemblies to catalyse controlled oxidation of benzyl alcohol to benzoic acid.

Age related changes in body composition are associated with long term dietary intake profiles. Age related increase in body fat is primarily attributed to decline in physical activity and basal metabolic rate as well as dietary intake. The study was designed to assess the body composition, dietary intake and physical activity level of sedentary adult women of different age groups. A cross-sectional study was conducted on 152 sedentary adult women comprised of students and faculty from Punjab Agricultural University, Ludhiana. The relationship of body composition with dietary factors and physical activity level of women in four age groups i.e. 21 - 30, 31 - 40, 41 - 50 and 51 - 60 years was determined. A gradual increase (p ≤ 0.05) in anthropometric and body composition parameters such as weight, waist circumference, hip circumference, body mass index, fat mass and visceral fat rating was observed with the advancement of age. The lean body mass was decreased significantly (p ≤ 0.05) as the age progressed, the values for four age groups being 74.9, 68.9, 62.8 and 60.9%, respectively. Contrary to this fat mass increased with age, the corresponding values for four age groups being 15.7, 21.4, 26.6 and 29.2 kg, respectively. The percent adequacy of protein by four age groups was 69.6, 78.2, 80.0 and 66.3, respectively when compared to RDA while fat intake was much higher i.e. 245.5, 271.8, 288.4 and 250.8%, respectively. The energy intake was inadequate among all age groups, however, a significant (p ≤ 0.05) differ- ence was observed in daily energy consumption between the age groups. The mean physical activity level (PAL) of the subjects ranged between 1.49 - 1.60. The physical activity level values showed that majority of the subjects (87% - 94%) were having sedentary life style. Age is a crucial factor associated with body composition. A high fat mass and low lean body mass of the subjects was observed. Their diets were low in protein but high in fat. Majority of the

AIM To establish the Karnofsky performance status(KPS) categories which would facilitate the interconversion of the KPS scale to the Eastern Cooperative Oncology Group(ECOG) performance status(PS) *** This was a retrospective analysis of all patients attending the lung cancer clinic at a tertiary care center over a 5-year period(September 2009 to August 2014). All patients were assessed with both KPS and ECOG PS scales at each visit. Correlation between KPS and ECOG PS was assessed using Spearman's correlation coefficient. KPS categories equivalent to ECOG PS scores were compared using hit rate and weighted kappa(κw).RESULTS A total of 1501 patients were assessed over the study period, providing 5844 paired KPS and ECOG PS assessments. The study cohort had a mean(standard deviation; SD) age of 58.4(10.8) years, with the majority being current or ex-smokers(76.9%) and males(82.3%). Non-small cell lung cancer was the most common histological type(n = 1196, 79.7%) with the majority having advanced(stage ⅢB/Ⅳ) disease(83.4%). Mean baseline KPS and ECOG PS scores were 77.6(SD = 14.4) and 1.5(SD = 1) respectively. The most frequent KPS score was 80(29%), and the most frequent ECOG PS score was 1(43%). The overall correlation between KPS and ECOG PS was good(Spearman r =-0.84, P < 0.0001) but ranged from-0.727 to-0.972 between visits. KPS categories derived from our cohort [10-40(ECOG 4), 50-60(ECOG 3), 70(ECOG 2), 80-90(ECOG 1), 100(ECOG 0)] performed better [hit rate 78.1%, κw = 0.749(0.736-0.762) P < 0.0001] than those suggested in the past *** The current study provides the largest set of paired KPS-ECOG assessments to date. We suggest that the KPS categories 10-40, 50-60, 70, 80-90, and 100 are equivalent to ECOG PS categories of 4, 3, 2, 1, and 0 respectively.

Jasmonates are class of plant growth regulators act as signal molecule that intercede various components in physiological and metabolic regulation, stress responses and possibly communication through signal transduction. Oxidative stress due to heavy metal exposure stimulates synthesis and activity of antioxidant metabolites and enhances antioxidant enzyme activities that could protect plant tissues. The aim of this study was to investigate the exogenous effect of JA at seed level which can transduce throughout seedling growth and regulate antioxidant activities such as superoxide dismutase (SOD;EC 1.***.1.1) and guaiacol peroxidase (POD;EC 1.***.1.7) in 12 days old seedlings of pigeon pea (Cajanus cajan (L.) Millsp.) in presence and/or absence of copper. The activity of SOD and POD increased significantly in presence of Cu2+ after seed priming with JA. JA also helps in chlorophyll and carotenoid accumulation and neutralizes the toxic effect of Cu2+ on seedlings. This is the first report of JA effect on photosynthetic pigment accumulation and H2O2 mitigating enzymes i.e. SOD and POD and it could be recommended that seed priming with JA help in ameliorating toxic effect of Cu2+.

Objective: To detect the prevalence pattern of Chikungunya virus in three states of Northeast India. Methods: A total of 1 510 samples were collected from different private and government hospitals of Assam, Arunachal Pradesh and Meghalaya. Serum was tested for the presence of IgM antibodies against Chikungunya virus followed by RT-PCR for amplification of Chikungunya E1 gene region using specific primers. Results: Overall, 11.83%(172/1 454) clinical samples were positive by MAC-ELISA and/or RT-PCR assay. Asymptomatic infection was seen in 17.86%. Males were more affected than females and age group 16-30 years was mostly affected. Fever(100.00%) was the primary symptom followed by headache(72.03%) and arthralgia(41.53%). Only 118 Chikungunya positive cases could be traced, of which 25.42% complained about sequelae of infection. In entomological investigation, Aedes aegypti was more predominant(92.10%) than Aedes albopictus(7.90%). No mosquito pools could be incriminated for Chikungunya virus. Conclusions: In this study, Chikungunya was observed to be prevalent in Assam, Arunachal Pradesh and Meghalaya. Though Chikungunya is a selflimiting infection, increasing morbidity by CHIKV infection is affecting social and economic status of individual. Thus, a community empowerment to effectively control mosquito population by employing different mosquito control measures along with personal protection is mandatory to tackle future outbreak of the disease.
