Plant mediated detoxification of mercury and lead

Brajesh Kumar, Kumari Smita, Luis Cumbal Flores
2017 Arabian Journal of Chemistry  
In recent years, the development of efficient green chemistry methods for detoxification of metal poisoning has become a major focus of researchers. They have investigated in order to find an eco-friendly and recyclable technique for the removal of heavy metal (Pb 2+ , Hg 2+ ) contamination from the natural resources. One of the most considered methods is the removal of Pb 2+ , Hg 2+ metal using green plants and their wastes. Among these plant wastes seem to be the best candidates and they are

Biosorption by plants involve complex mechanisms, mainly ion exchange, chelation, adsorption by physical forces and ion entrapment in inter and intra fibrillar capillaries and spaces of the structural polysaccharide cell wall network. The advantages of using green plants and their wastes for detoxification of heavy metal have interested researchers to investigate mechanisms of metal ion uptake, and to understand the possible utilization. In this review, we discuss the role of plants and their wastes for minimizing mercury and lead pollution with their toxic effect on both human beings and plants. ª 2014 Production and hosting by Elsevier B.V. on behalf of King Saud University.

Neonatal and maternal outcome in oligohydramnios: a prospective study

Rizwan Ahmar, Sadia Parween, Smita Kumari, Manish Kumar
2018 International Journal of Contemporary Pediatrics  
Oligohydramnios presents a threat to the fetus and has been correlated with increased risk of intrauterine growth retardation, meconium aspiration syndrome, severe birth asphyxia, low APGAR scores and congenital abnormities. It is associated with perinatal morbidity and mortality and maternal morbidity in a significant number of cases. Therefore, early detection of oligohydramnios and its management is important. Aim of this study was to know the fetal and maternal outcome in

All required investigation done. Oligohydramnios confirmed by measuring Amniotic fluid index (AFI).Results: Mean maternal age-26.1 years. Incidence of oligohydramnios was more in primipara (64.4%) in our study. And operative morbidity was also more in primipara (51.7%). Most common cause of Oligohydramnios was idiopathic (44.44%). Operative morbidity was significantly higher in Non-reassuring FHR (80%) than reassuring FHR (32%). 7 patients (7.78%) were found with fetoplacental insufficiency on Doppler study.Conclusions: Oligohydramnios is frequent occurrence and demands intensive fetal surveillance and proper antepartum and intrapartum care so that perinatal morbidity and mortality and maternal morbidity can be reduced.

Why parents consent to their children's participation in genetic research: A study of parental decision making

Sunita Kumari, Triptish Bhatia, Nagendra N Mishra, Nupur Kumari, Sreelatha S Narayanan, Deepak Malik, Smita N Deshpande
2019 Indian Journal of Medical Ethics  
Parents need to be asked to provide informed consent on behalf of their child for participation in genetic research. Decision making for such parents is difficult because ethical challenges in paediatric genetic research studies are different from similar adult studies. This paper focuses on interviews conducted with parents who were asked to consent to their children's participation (or not) in a genetic research study of intellectual disability and/or autism.

Brajesh Kumar, Kumari Smita, Luis Cumbal, Alexis Debut
2017 Saudi Journal of Biological Sciences  
Green synthesis of nanoparticles using various plant materials opens a new scope for the phytochemist and discourages the use of toxic chemicals. In this article, we report an eco-friendly and low-cost method for the synthesis of silver nanoparticles (AgNPs) using Andean blackberry fruit extracts as both a reducing and capping agent. The green synthesized AgNPs were characterized by various analytical instruments like UV-visible, transmission electron microscopy (TEM), dynamic light scattering

TEM analysis of AgNPs showed the formation of a crystalline, spherical shape and 12-50 nm size, whereas XRD peaks at 38.04°, 44.06°, 64.34°and 77.17°confirmed the crystalline nature of AgNPs. FTIR analysis was done to identify the functional groups responsible for the synthesis of the AgNPs. Furthermore, it was found that the AgNPs showed good antioxidant efficacy (>78%, 0.1 mM) against 1,1-diphenyl-2-picrylhydrazyl. The process of synthesis is environmentally compatible and the synthesized AgNPs could be a promising candidate for many biomedical applications.
