Iodine content of rice (42) and drinking water (108) from a goitre-endemic belt of Assam, a sub-Himalayan zone of India, was evaluated. Iodine content of staple food (rice) and drinking water was found to be poor. Mean iodine content of rice was found to be 11.8 +/- 7.3 micrograms/100g. Lower level of iodine was also observed in drinking water samples (mean of 1.52 +/- 0.48 micrograms/l). 相似文献

Background: Vector-borne diseases such as malaria, dengue, yellow fever, encephalitis and filariasis are considered serious human health concerns in the field of medical entomology. Controlling the population of mosquito vectors is one of the best strategies for combating such vector-borne diseases. However, the use of synthetic insecticides for longer periods of time increases mosquito resistance to the insecticides. Recently, the search for new environmentally friendly and efficient insecticides has attracted major attention globally. With the evolution of material sciences, researchers have reported the effective control of such diseases using various sustainable resources. The present investigation demonstrates a potent on-site biolarvicidal agent against different mosquito vectors such as Aedes albopictus, Anopheles stephensi and Culex quinquefasciatus. Methods: Stable and photo-induced colloidal silver nanoparticles were generated via the surface functionalization of the root extract of Cyprus rotundas. Characterizations of the nanoparticles were performed using assorted techniques, such as UV-visible spectroscopy, FTIR spectroscopy, DLS and HRTEM. The bioefficacy of the synthesized nanoparticles was investigated against different species of mosquito larvae through the evaluation of their life history trait studies, fecundity and hatchability rate of the treated larvae. Histopathological and polymerase chain reaction-random amplified polymorphic DNA (RAPD) analyses of the treated larvae were also examined to establish the cellular damage. Results: The synthesized nanoparticles showed remarkable larvicidal activity against mosquito larvae in a very low concentration range (0.001–1.00) mg L−1. The histopathological study confirmed that the present nanoparticles could easily enter the cuticle membrane of mosquito larvae and subsequently obliterate their complete intestinal system. Furthermore, RAPD analysis of the treated larvae could assess the damage of the DNA banding pattern. Conclusion: The present work demonstrates a potent biolarvicidal agent using sustainable bioresources of the aqueous Cyprus rotundas root extract. The results showed that the synthesized nanoparticles were stable under different physiological conditions such as temperature and photo-induced oxidation. The effectiveness of these materials against mosquito larvae was quantified at very low dose concentrations. The present biolarvicidal agent can be considered as an environmentally benign material to control the mosquito vectors with an immense potential for on-site field applications.The present work demonstrates a potent and stable biolarvicidal agent using sustainable bioresources. The synthesized nanomaterials can control the mosquito vectors at a very low concentration range (0.01–1.00 mg L−1) for on-site field applications. 相似文献

Correction for ‘Realization of multi-configurable logic gate behaviour on fluorescence switching signalling of naphthalene diimide congeners’ by Hridoy Jyoti Bora et al., RSC Adv., 2021, 11, 35274–35279. DOI: 10.1039/d1ra06728a.The authors regret that there was an error in the sentence in lines 24–27 in the left column on page 35278 of the original article. The text originally read, “Mass spectrometric data Shimadzu UV-Vis spectrophotometer, UV-2600 is used to record the absorption spectra were gained from a THERMO 3000 Exactive Plus Orbitrap Mass Spectrometer”. This sentence should read, “Mass spectrometric data were gained from a THERMO 3000 Exactive Plus Orbitrap Mass Spectrometer. Shimadzu UV-Vis spectrophotometer, UV-2600 is used to record the absorption spectra”.The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers. 相似文献

Protein misfolding is an intrinsic aspect of normal folding within the complex cellular environment. Its effects are minimized in living system by the action of a range of protective mechanisms including molecular chaperones and quality control systems. According to the current growing research, protein misfolding is a recognized key feature of most neurodegenerative diseases. Extensive biochemical, neuropathological, and genetic evidence suggest that the cerebral accumulation of amyloid fibrils is the central event in the pathogenesis of neurodegenerative disorders. In the first part of this review we have discussed the general course of action of folding and misfolding of the proteins. Later part of this review gives an outline regarding the role of protein misfolding in the molecular and cellular mechanisms in the pathogenesis of Alzheimer's and Parkinson along with their treatment possibilities. Finally, we have mentioned about the recent findings in neurodegenerative diseases. 相似文献

The return of fertility following discontinuation of norethisterone oenanthate (NET EN) 200 mg injectable contraceptive after use for a minimum period of six months or more was studied in 69 women who discontinued the method for planning pregnancy. Former users of copper intra-uterine device (CuT 200) were enrolled as a control group. Another 161 women who had discontinued NET EN due to other reasons (e.g. amenorrhoea, excessive bleeding or personal reasons) were also studied for return of fertility after ensuring that they were not using any other method of contraception and were exposed to the risk of pregnancy. The subjects from both groups were followed for a period of one year. The cumulative conception rates at one year were 72.5 and 83.6 per 100 subjects for ex-NET EN and ex-CuT 200 users who had discontinued the method for planning pregnancy and this difference was not statistically significant (P > 0.05). The median time for conception for ex-NET EN users was 7.8 months as compared to 3.7 months in ex-CuT 200 users but the cumulative conception rates at the end of one year show that future return of fertility in NET EN users does not appear to be adversely affected.
In 51 subjects who had discontinued NET EN due to amenorrhoea, the return of fertility was predictably slower and less. The return of fertility in subjects who discontinued NET EN for other reasons (e.g. excessive bleeding and other personal reasons) was similar to ex-NET EN and ex-CuT 200 users. 相似文献
