A Review Study On Biodiversity Of  Eastern  Himalaya  And  Its Conservation Strategies Rajkumar Yadav Biodiversity,Conservation,Flora And Fauna. The Eastern Himalaya is one of the most ecologically diverse regions on Earth, serving as a critical biodiversity hotspot with high levels of endemism. Spanning northeastern India, Bhutan, south eastern Tibet, and northern Myanmar, this region harbors thousands of plant and animal species, many of which are endangered. However, rapid environmental changes, deforestation, habitat fragmentation, climate change, and anthropogenic pressures threaten its biodiversity. This review synthesizes existing literature on the biodiversity of the Eastern Himalaya and examines conservation strategies, including protected areas, community-based initiatives, and trans boundary co-operation. Strengthening these strategies through policy implementation, local engagement, and scientific research is essential for safeguarding the region’s rich ecological heritage.

Review Of A Research Paper On Magnetosomes Rajkumar Yadav Avshesh Kumar Vishal Pundir Nanoparticles, magnetosomes, significant, biomedical, biophysical Magnetosomes, biologically synthesized magnetic nanoparticles found in magnetotactic bacteria, have attracted significant research interest due to their unique structural and magnetic properties. This paper explores the formation, organization, and applications of magnetosomes in nanotechnology and biomedical fields. The study builds on prior research, including the pioneering work of Blakemore (1975) on magnetotactic bacteria and the genetic studies by Schüler (2008) on magnetosome formation. Using high-resolution electron microscopy, genetic analysis, and magnetic characterization techniques, the paper provides new insights into the role of specific genes, as previously suggested by Komeili (2012). The study further expands on the findings of Faivre and Schüler (2008) regarding the biophysical properties of magnetosomes. Finally, the applications of magnetosomes in biomedicine, as discussed by Alphandéry (2014) and Sun et al. (2017), are evaluated in light of new experimental data.

A Review on the Impact of Chemicals Used in Crops on Human Health Rajkumar Yadav pesticides; fertilizers; agrochemicals; residues; human exposure; endocrine disruption; neurotoxicity; carcinogenicity; nitrates; cadmium; integrated pest management; food safety; maximum residue limits Modern crop production relies on a wide array of chemicals—including pesticides, synthetic fertilizers, plant growth regulators, and post-harvest treatments—to secure yields and reduce losses. While these inputs contribute to food security, accumulating evidence links both occupational and dietary exposures to a spectrum of human health outcomes. Documented risks range from acute poisonings and irritant effects to chronic neurobehavioral changes, endocrine disruption, reproductive toxicity, carcinogenicity, cardiometabolic disease, and perturbed gut microbiomes. Risk varies with compound class, formulation, dose, timing, and life stage, and is modified by regulatory controls, residues at consumption, and mitigation practices across the farm-to-fork chain. This review synthesizes epidemiological, toxicological, and risk-assessment evidence; highlights vulnerable populations; summarizes regulatory approaches (ADI, ARfD, MRLs); and identifies practical risk-reduction strategies such as integrated pest management (IPM), safer formulations, improved application practices, and consumer-level decontamination. We conclude with research and policy priorities to align agricultural productivity with human health protection.

Ornamental plants beautify landscapes while delivering ecological, economic, and health benefits (Elmqvist et al., 2019; Millennium Ecosystem Assessment, 2005). They regulate microclimate, filter air, support biodiversity, and improve wellbeing (Bowler et al., 2010; Nowak et al., 2014; Baldock et al., 2015; Ulrich, 1984). Risks include invasiveness, allergenicity, and high inputs (Reichard & White, 2001; Cariñanos & Casares-Porcel, 2011). Contemporary practice emphasizes native, low-input, climate-resilient palettes and nature-based solutions (Roloff, 2016; IPBES, 2019; Berland et al., 2017).

Plant-Based Foods Vs. Animal-Based Foods: A Comprehensive Review on Their Impacts on Human Health Avshesh kumar plant-based diet, animal-based diet, nutrition, human health, cardiovascular disease, antioxidants, protein quality, sustainability, chronic diseases Human diets are broadly classified into plant-based and animal-based categories, each offering distinct nutritional and health implications. The debate over which type of diet is more beneficial for human health has gained significant attention in recent years due to the rising prevalence of chronic diseases, lifestyle disorders, and environmental concerns. Plant-based diets emphasize fruits, vegetables, grains, legumes, and nuts, rich in fiber, antioxidants, vitamins, and phytochemicals that promote longevity and reduce disease risk. In contrast, animal-based diets are dense in protein, essential amino acids, vitamin B12, and omega-3 fatty acids, but excessive consumption has been linked to cardiovascular diseases, diabetes, and certain cancers. This review aims to compare the nutritional, physiological, and epidemiological impacts of plant and animal food consumption on human health, highlighting the balance required between the two for optimal well-being.

Effect of Pharmaceutical Residues on Aquatic Ecosystems Avshesh Kumar Green roofs, Urban greening, Nature-based solutions, Stormwater, Urban heat island, Biodiversity, Air quality, Energy efficiency, Sustainability. Pharmaceutical residues have emerged as persistent organic micropollutants in aquatic ecosystems worldwide. These residues originate primarily from domestic sewage, hospital discharges, pharmaceutical manufacturing, and agricultural activities. Due to their chemical stability, bioactivity, and low biodegradability, pharmaceuticals persist in the environment, accumulating in sediments and biota. Their presence at even trace concentrations can lead to hormonal disruptions, behavioral alterations, and toxicity in aquatic organisms. This review highlights the pathways, persistence, ecotoxicological effects, and mitigation strategies of pharmaceutical residues in aquatic ecosystems. The findings emphasize the urgent need for sustainable management strategies and innovative wastewater treatment technologies to protect aquatic biodiversity and ecosystem health.
