Length-weight relationship and condition factor of Perna viridis (Linnaeus, 1758) and Meretrix meretrix (Linnaeus, 1758) from Mumbai waters

Length weight relationship of the two commercially important molluscs P. viridis and M. meretrix was found to be W=-0.40263L super(2.044719) & W=-0.04359L super(2.2315498) respectively. Condition factor was recorded to be less than 1.0 for most part of the year in P. viridis and for M. meretrix it ranged from 0.39 to 4.61. The present study reveals that there was allometric growth in both the species and the growth was not satisfactory since it showed lower K-value during most part of the year

Impact of community-based presumptive chloroquine treatment of fever cases on malaria morbidity and mortality in a tribal area in Orissa State, India

<p>Abstract</p> <p>Background</p> <p>In the Global Strategy for Malaria Control, one of the basic elements is early detection and prompt treatment of malaria cases, especially in areas where health care facilities are inadequate. Establishing or reviving the existing drug distribution centers (DDC) at the peripheral levels of health care can achieve this. The DDCs should be operationally feasible, acceptable by community and technical efficient, particularly in remote hard-core malaria endemic areas.</p> <p>Methods</p> <p>Volunteers from villages were selected for distribution of chloroquine and the selection was made either by villagers or head of the village. The services of the volunteers were absolutely free and voluntary in nature. Chloroquine was provided free of charge to all fever cases. The impact was evaluated based on the changes observed in fever days, fever incidence, parasite incidence and parasite prevalence (proportion of persons harbouring malaria parasite) in the community. Comparisons were made between 1st, 2nd and 3rd year of operation in the experimental villages and between the experimental and check areas.</p> <p>Results</p> <p>A total of 411 village volunteers in 378 villages in the experimental community health center with a population of 125,439 treated 88,575 fever cases with a mean annual incidence of 331.8 cases per 1,000 population during the three-year study period. The average morbid days due to fever (AFD) was reduced to 1.6 ± 0.1 from 5.9 ± 2.1 in the experimental villages while it remained at 5.0 ± 1.0 in the check villages. There was a significant reduction, (p < 0.05) in Annual Fever Incidence (AFI) in the experimental hilltop and foothill villages in comparison to check villages. The change in Annual Parasite Incidence (API) was, however, not statistically significant (p > 0.05). In plain villages that were low endemic, the reductions in AFI and API in experimental villages were statistically significant (p < 0.05). There was significant reduction in the parasite prevalence in high endemic villages of the experimental area both during 2^ndand 3^rdyear when compared with the check area (p < 0.05) but no such reduction was observed in low endemic areas (p > 0.0.5). Mortality due to malaria declined by 75% in the experimental villages in the adult age group whereas there was an increasing trend in check villages.</p> <p>Conclusion</p> <p>The study demonstrated that a passive chloroquine distribution system operated by village volunteers in tribal areas is feasible and effective in reducing malaria-related morbidity and mortality.</p

Association of PPARα Intron 7 Polymorphism with Coronary Artery Disease: A Cross-Sectional Study

The allelic variants of peroxisome proliferator-activated receptor alpha (PPARα) can influence the risk of coronary artery disease (CAD) by virtue of its effect on lipid metabolism. However, the role of PPARα intronic polymorphism with CAD has received little attention. The association of allelic variants G/C at intron 7 of the PPAR-alpha gene with CAD was examined in a hospital-based Indian population. PPAR genotyping was performed in 110 male patients with CAD and 120 age and ethnically matched healthy males by PCR amplification of the gene followed by restriction digestion. Presence of C allele showed a positive association with CAD (OR = 2.9; 95% CI [1.65–4.145]; P = .009) and also with dyslipidaemia (OR = 2.95, 95% CI (1.5–4.39); P < .05). Impaired lipid metabolism in carriers of the PPARα Intron 7C allele is possibly responsible for the predilection to CAD

Spirituality Scale: Development and Validation

The genesis of spirituality is challenging due to a wide variety of perspectives and assumptions underlying spirituality research. Spirituality is still an emerging concept in the developing countries such as India, although rich culture has enriched in the past. Confining to various definitions of spirituality, the study attempts to evolve a health oriented spirituality scale in an Indian context. With exploration of literature and expert reviews, various attributes of spirituality scale were initiated with a pool of 120 items. These items were subjected to experts’ opinion and were reduced to 77. The version I scale was then administered on a sample of 254 participants. After initial factor analyses, the scale was again administered on a sample of 104 participants. Principal component analyses were employed and 56 items were retained covering five factors for final version of Spirituality Scale. The reliability was 0.640 and validity was 0.491

Copper, zinc, iron and manganese in sediments and in the rock oyster Saccostrea cucullata in Mumbai coast

Sediment and oyster (Saccostrea cucullata) samples were collected at Dhanda, a fishing village in Mumbai, Maharashtra. The samples were analysed for copper, zinc, iron and manganese contents. Metal concentrations in the sediments and bioaccumulated levels in oysters were correlated. There is no positive correlation between the total sedimentary levels of metals analysed and the bioaccumulated levels of respective metals in oyster. A positive correlation between the bioavailable fractions of zinc, iron and manganese, and the bioaccumulated levels exists. Copper, however, shows a negative correlation with respect to the bioaccumulated levels
