The phytoremediation technique is highly advantageous involving the natural processes of plants viz., translocation, evapotranspiration, and bioaccumulation, thus degrading contaminants slowly. In particular, nanophytoremediation is a rapid green alternative as it reduces the ancillary impacts of the environment such as green gas emissions, waste generation, and natural resource consumption to the present scenario as there is a great potential of nanoparticles from plants which can be synthesized. Nanophytoremediation is a current methodology for remediation of pollutants, contaminants by using synthesized nanoparticles from plants. In this, the use of different strategies enhances the selective uptake capabilities of plants. The metal elements in excess are affecting the physiological processes in plants; thus, it is necessary to apply nanophytorem...

They exist in various fields of engineering and science such as electronics, agriculture, food, pharmaceuticals, and medical diagnostics, and many researchers are eyeing provision of better technology with these nanotechnological inventions. Nanomaterials show great promise, owing to their unique physicochemical properties, in the field of agriculture. Plants interact with these nanoparticles, resulting in various morphological, physiological, and genotoxic changes. Understanding of their interactions is very important for real gains in the potential use of nanotechnology in agriculture. Nanoparticles have been described as “magic bullets.” Nanoparticles can play a vital role in the growth of plants and help in the process of photosynthesis. They also influence the key processes that take place in the growth of plants, such as seed germination, root initiation, and the ph...

The Indian apple snail, Pila globosa and other operculate snails are grouped in Architaenioglossa which also includes Viviparidae and Cyclophoridae. In our study, a concise relationship of Ampullariidae with Viviparidae and Cyclophoridae has been elucidated by using partial nucleotide sequence of cytochrome b gene. Pila globosa was collected from freshwater habitats of Berhampore (West Bengal) and its morphometric analysis is determined as an addendum to its phylogeny. The multiple sequence alignment is performed in MEGA v5.2 to reconstruct molecular affinities within the family, Ampullariidae. The phylogenetic tree is constructed with 1000 bootstrap replications in RAxML software. The outgroup species considered for the analysis in our study is chosen from Heterobranchia as it is a sister group to the clade Caenogastropoda. It is observed that family Ampullariidae formed a n...

Although darbepoetin alfa can effectively increase hemoglobin levels, its effect on clinical outcomes in these patients has not been adequately tested.
