Copper plays an important role in various body functions and regulation of different pathways. Hence, it has been used since pre-Vedic time as potential medicine to cure a number of diseases. Although, copper has significant medicinal value, the maintenance of adequate copper levels in the body is of vital importance because the lack or excess amount of such essential trace elements are known to cause a variety of health problems. The failure in the regulation of copper metabolism is mainly responsible for deficiency and accumulation of copper in different parts of the body. Generally, deficiency of copper leads to several copper deficiency syndromes including Menkes’ disease. Similarly, high level of copper due to accumulation results in many diseases like Wilson’s diseases, Alzheimer’s disease, etc. Considering the key role of copper in human health, the present chapter has been focused on such related aspects, which include uptake and metabolism of copper, and its dietary recommendations. In addition, various disorders caused due to deficiency and excess amount of copper are also discussed in detail.

Pythium and Fusarium spp. are pathogens responsible for the deteriorating disease in ginger known as soft- or rhizome-rot, causing more than 50% loss of ginger crop worldwide. The application of chemical fungicides is a promising method for control of soft-rot in ginger. But use of such fungicides is harmful to both environment and human health. Thus, there is an obligatory need for the search of an eco-friendly and economic approach for the control of soft-rot in ginger. Various physical, chemical, and biological methods have already been in practice since many years for managing soft-rot in ginger. This chapter primarily focuses on the advantages of biological control over chemical methods of Pythium and Fusarium spp. management using antagonistic fungi, bacteria, actinomycetes, and plant extracts.

Various treatment strategies have been investigated but the label of low therapeutic success is always associated with them. The main reason behind the low success rate is active drug molecules that are unable to reach their target sites of action inside the body. In addition, various CNS barriers such as the blood-brain barrier, the blood-cerebrospinal fluid barrier, etc., always hinder the circulation of therapeutic drugs in the body. Therefore, considering the last decade's contribution of nanotechnology in the biomedical sector, it is believed that the problem of ever-increasing neurological disorders can only be managed by nanotechnology. Nanotechnology offers many exciting and promising new means of treating neurological disease. In this chapter, we have mainly focused on various aspects related to CNS diseases involving current treatment strategies and their limitations, the necessity of nanoneuromedicines, the role of nanotechnology in the diagnosis and treatment of CNS diseases, and toxicological issues.

Biofertilizers obtained from algae are identified as novel production fertilizers or innovative biofertilizers without the detrimental impacts of chemicals. Seaweeds contain many water-soluble minerals and nutrients that plants can easily absorb and that are valuable for crop plants’ growth. At present, Ascophyllum nodosum (L.) Le Jolis extract outperforms chemical fertilizers in terms of increasing seed germination, plant development, and yield, as well as protecting plants from severe biotic and abiotic stresses. A. nodosum contains bioactive compounds that exhibit an array of biological activities such as antibiotic, anti-microbial, antioxidant, anti-cancer, anti-obesity, and anti-diabetic activities. A. nodosum extract (AnE) contains alginic acid and poly-uronides that improve soil’s water-carryi...

In this study we report the use of Azadirachta indica (Neem) Gum as a novel natural precursor for synthesis of CDs at room temperature. Water soluble CDs of around 5-8 nm were obtained after treatment of the gum with ethanol and NaOH. These CDs exhibited green fluorescence in UV-light (λ = 365 nm). These CDs were found to be stable, having many bio-linkers attached on their surface, making it suitable for drug attachment and hence can serve as potential candidates for applications like drug delivery vehicles as well as for biosensors.

The widespread use of Pt nanoparticles (NPs) in gas neutralizers for automobile exhaust has sharply increased the amount of PtNP pollution in the environment, including forest ecosystems. Recently, territories with Pt concentrations greater than 0.3 mg/kg in soil have been discovered. This concentration is 750 times greater than the background content in the earth’s crust. Cambisols, the most prevalent forest soil type in boreal forests that determines the functioning of the entire forest ecosystem, occupy a significant share of the Earth’s soil cover, which is about 1.5 billion hectares worldwide, or 12% of the entire continental land area. This shows the importance of studying the effect of pollution on this type of soil. In this study, laboratory simulations of PtNP contamination of the Haplic Cambisols Eutric at concentrations of 0.01, 0.1, 1, 10, and 100 mg/kg were carried out. The effect of PtNPs on soil p...

However, mining and processing companies cause significant soil contamination by heavy metals, in particular, copper (Cu). The resistance of nine types and subtypes of forest soils of the dry and humid subtropics in the Greater Caucasus region to Cu contamination at concentrations of 100, 1000, and 10,000 mg/kg was evaluated for the first time following the most sensitive and informative biological (microbiological, biochemical, and phytotoxic) indicators via a laboratory simulation study. Contamination was simulated under laboratory conditions. The series of forest soils was established following their resistance to Cu pollution: brown leached soils (Haplic Cambisols Eutric) = brown typical soils (Haplic Cambisols Eutric) > brown carbonate soils (Haplic Cambisols Eutric) = sod-carbonate typical soils (Rendzic Leptosols Eutric) ≥ yellow soils (Albic Luvisols Abruptic) ≥ leached sod-carbonate soils (Rendzic Lep...

Here, we synthesized silver nanoparticles using encapsulated biomass beads of Phoma exigua var. exigua. Nanoparticles were characterized by nanoparticle tracking and analysis (NTA), Fouriertransform infrared spectroscopy, X-ray diffraction, transmission electron microscopy and zeta potential. Results of NTA show that nanoparticle size was homogenous. Concerning nanoparticle stability, zeta potential decreased with batch number. Silver nanoparticles exhibited an antibacterial activity against Escherichia coli and Staphylococcus aureus. Overall, the encapsulation of fungal biomass by calcium alginate for the batch synthesis of silver nanoparticles was easy, cost-effective, eco-friendly and suitable for the large-scale synthesis of silver nanoparticles. We have also demonstrated the reusability of the fungal biomass during biosynthesis of silver nanoparticles using the sodium alginate encapsulation method.
