We played out a thorough meta-examination that included hybrid investigations and controlled preliminaries randomly chosen to account for this uncertainty. Our findings add to the ongoing discussion surrounding this issue and provide useful information regarding the possibility that vitamin D plays a role in the treatment of type 2 diabetes. In this systematic review, we wanted to provide a comprehensive overview of the most recent data on the effects of vitamin D on people with type 2 diabetes. We searched multiple databases in accordance with PRISMA guidelines and found 40 relevant studies published between 2015 and 2022. may make the disease more likely to happen to you. However, other considerations, such as one's lifestyle, diet, and genetic predisposition to type 2 diabetes, are essential. Converse...

Resistance in the larvae was monitored by subjecting selection pressure using B. sphaericus 1593M at every generation. Bioassays were conducted with different strains of B. sphaericus (Bs 2297, Bs 2362 and Bs IAB 59) and confirmed cross-resistance in the present study. The level ranged between 27.3 to 18.2 fold in comparison with susceptible larvae. But Bacillus thuringiensis var israelensis strains (Bti PG14 and Bti 426) did not show any cross-resistance in the larvae and it emphasized a need to study the mode of action of B. sphaericus toxin that induces cross-resistance in the larval strain.

They provide the community various aspects of socio-cultural apart from health messages and thus contribute to the overall development of the society in a healthy environment. “Obesity” is a double burden of disease and a widely discussed malnutrition problem in the country. In the recent past, media has given more impetus to health aspects in their news coverage apart from other subjects. In this context, a study was conducted on popular daily newspapers and its representations of the issue of overweight and obesity. Objectives: To study how overweight/obesity is framed in the media and to measure misrepresentation of overweight/obesity, if any. Materials and Method: Three leading English dailies, Deccan Chronicle, The Hindu and The Times of India and three Telugu dailies, Eenadu, Andhra Jyothi and Andhra Bhumi were selected for the study.

Larvae from the sprayed area gave LC50 and LC90 values that were 146 and 180 times greater than corresponding values for a susceptible strain from an unsprayed locality. When the resistant strain was colonized in the laboratory and subjected to moderate selection pressure at each generation, resistance rapidly increased and by the 18th generation it was 6,223 and 31,325 times greater at the LC50 and LC90 levels in comparison with the susceptible strain. There were no significant differences among 6 susceptible strains tested. Tests were repeated and validated using the standard primary powder SPH88, B. sphaericus 2362. No cross resistance was observed against B. thuringiensis H-14.

There is a dearth of data from India on the effectiveness of different communication tools in providing nutrition education to student volunteers. This study aims to examine the comparative effectiveness of two different methods of communication--lectures in the classroom aided by print material, and a televised version of a local folk-dance form--for providing nutrition education to student community volunteers in a South Indian state. Interventions were conducted during two mega-camps of student volunteers (camps 1 and 2) with 70 and 137 participants, respectively. Their knowledge levels were tested at baseline. Camp 1 received the lecture intervention and camp 2 the televised folk-dance intervention. Knowledge scores were measured before and after the intervention in each camp, and the two camps were compared for significant improvements in knowledge. At baseli...

How far mass media, particularly the print media in India is catering the needs of the readers with health and nutrition information? Is the quantity of the health and nutrition information is same or varies between English and regional newspapers? To answer these questions, a quantitative analysis was conducted on English (The Hindu) and Telugu (Eenadu) newspapers pertaining to nutrition and health messages during the month of February, 2010. The percentage of space occupied by health topics in both the newspapers put together was 2.30%. For nutrition topics even less than 1% space was provided. Indian print media's contribution in dissemination of health and nutrition information is meager. Quantity of health and nutrition information catered by regional language daily is less than the English newspaper. Regional language newspaper readers are mostly consist of economically backward and prone to undernutrition. This segment was not supplied with adequate amount of information on nutrition. Regularity to be followed in publishing health and nutrition news in regional newspapers.

Relatively stable lipid-rich fractions of neem were shown to be as effective as good-quality crude neem products in control of breeding of culicine vectors of Japanese encephalitis, and also produced a slight but significant reduction in populations of anopheline pupae. Neem-based formulations coated over urea significantly increased grain yield, but used alone did not, whereas combining the use of neem-coated urea and water management by intermittent irrigation had a greater effect on grain yield than that of water management alone. The neem fractions were relatively cost-effective, and the combined water management and neem-coated urea strategy is acceptable to farmers, who are already aware of the benefits of the use of neem-coated urea, and of water management. This technology therefore has considerable promise as an environmentally benign method of rice-field mosquito control that could be sustainably implemented by farmers.

Statistically significant reductions of indoor-resting and man-biting densities of the mosquitoes Anopheles subpictus and Culex quinquefasciatus were observed for 14 weeks, in two field trials. Bioassays on curtains in the field showed over 50% mortality of Cx quinquefasciatus and An.stephensi for up to 8 weeks. The curtains were highly acceptable to the community, and cost approximately Rs.33.15 (US$1.05) for material and Rs.10 ($0.32) for delta-methrin per hut, totalling Rs 53.15 ($1.70) for two impregnations giving 6 months protection. Comparative costs of house-spraying with residual insecticides are estimated as Rs.1.92 ($0.06) for two rounds of DDT at 1 g/m2, or Rs.40 ($1.27) for three rounds of malathion at 2 g/m2. Therefore the relative annual cost of protection using deltamethrin-impregnated hessian curtains is 28 x or 1.3 x more than for house-spraying with DDT or malathion, respectively (excluding operational expenditure).

The results indicated that the two biopesticides have no synergistic interaction on the larvae. These results are discussed in light of earlier experiments with resistant C. quinquefasciatus, in which Bspfc-Neemtox synergism was seen.Résumé—Des bioessais ont été conduits séparément et selon différentes combinaisons, avec Bacillus sphaericus (Neide) 1593M (Bsph) et une formulation de biopesticide à base de neem., Neemtox® (0.03% azadirachtine), pour évaluer d'éventuels effets synergiques sur des larves de Culex quinquefasciatus Say (Diptera: Culicidae) sensibles au Bsph. Les résultats indiquent que les deux biopesticides n'ont pas d'action synergique sur les larves. On discute de ces résultats à la lumière d'expérimentations antérieures conduites sur des C. quinquefasciatus résistants pour lesquels un synergisme Bsph-Neemtox a été observe.

Design: Purposive sampling technique was adapted for selecting the subjects in the study. Setting: Four secondary schools in Hyderabad, India. Subjects: In total, 164 adolescent girls belonging to eighth grade. Interventions: Two interventions (Intervention-1. Traditional method using print media such as folders leaflets and charts; Intervetion-2. Audiovisual CD) were carried out in a classroom setting for the experimental group. Results: FFQ data on dietary consumption of adolescent girls revealed more consumption of aerated drinks, bakery items, fast foods and less consumption of millets irrespective of their socioeconomic conditions. However, consumption of vegetables, green leafy vegetables and fruits was moderate. A significant improvement in the nutrition related knowledge was observed among the experimental group after interventions-1 and-2 as compared to the baseline data. However, no significant difference in the improvement of nutrition knowledge levels was observed with the second intervention over the first intervention as already the children in the experimental group gained knowledge through print media. Conclusions: Education on ill effects of aerated drinks, fast foods and the importance of nutrition during the adolescent phase should be emphasized in future programmes.
