ABSTRACT
Background: Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health. Obesity has become a global public health issue and is widely recognized as a key risk factor for coronary heart disease, hypertension, diabetes and many other health problems. The objectives of present study were to assess the prevalence of overweight and obesity and its association with socio-demographic factors amongst school-going adolescents in Lucknow district.Methods: This study was a school-based cross-sectional study and was carried out in urban and rural areas of Lucknow, from January 2018 to June 2018. Sample size was 620. A multi-stage random sampling technique has been used to select the required sample size. Data analysis was done using software MS Office excel and SPSS 18 for windows.Results: A total of 620 adolescents were studied. Majority (82.1%) of adolescents were found to be non-overweight/obese while 17.9% were found to be overweight/obese. Majority (66.7%) of students were overweight or obese, belonging to social class I while only 15.7% students were overweight or obese belonging to social class V.Conclusions: The results of our study show that overweight/obesity continues to be a public health concern in adolescents. The current study shows that adolescent overweight and obesity are increasing even in low socio-economic status. Emphasis should be placed on awareness program for obesity prevention among school students by strengthening lifestyle change.
ABSTRACT
Any damage at molecular or cellular level is the major culprit for disease & ill health. Nanotechnology, “the manufacturing technology of the 21st century," helps us economically build a broad range of complex molecular machines by manipulating matter on an atomic and molecular scale. Nanotech may be able to create many new materials and devices with at least one dimension sized from 1 to 100 nanometres with a vast range of applications, such as in medicine, electronics, biomaterials and energy production. Lots of new possibilities come into account in relation to use of nanotechnology in medicines. Nanotechnology in medicine involves applications of nanoparticles, also involves nano-robots to make repairs at the cellular levels. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials.
ABSTRACT
We used random amplification of polymorphic DNA (RAPD) to generate species-specific diagnostic fragment patterns for the molecular identification of the ornamental aquarium fish species Badis badis and Dario dario. Seven arbitrary oligodecamer primers produced a total of 116 bands of which 98.23 percent were polymorphic. The size of the amplified products was in the range 340 bp to 2170 bp. Intraspecies genetic similarity was 0.879 ± 0.023 for B. badis and 0.840 ± 0.014 for D. dario while interspecies genetic similarity was 0.602 ± 0.017, with cluster analysis displaying separate taxonomic and evolutionary status for these fish. The results show that RAPD was useful for the molecular identification of aquarium fish species, with morphological traits also being important.
