Abstract	Water pollutants are an emerging environmental hurdle for crop production and human health risks. In recent decades, the removal of contaminants from water using a cutting-edge approach like biosorbents is a strategy that is both cost-efficient and sustainable. For instance, since biowaste from fruit crops implies the frequent occurrence of average annual waste, it is imperative to formulate strategic initiatives to mitigate this emerging problem while simultaneously recognizing the potential for reutilization and reintroduction of such waste into the industrial sector. Fruit crops such as peels, seeds, skins, branches and stalks can be altered into biosorbents for water treatment. Partially mitigating the adverse impacts of biowaste that estimate to incur costs of billions of dollars around the world would be achieved with this engineering application. This review provides a perspective on the existing literature and brings up-to-date information and findings in the field of pomological crop waste as biosorbents for environmental remediation. In this way, we review the detrimental impact of environmental contaminants on biological organisms and different types of fruit crop waste and their utilization for wastewater treatment, with special emphasis on the formulation of biowaste sorbents (removal efficiency is > 80%) and their application for capturing pollutants such as heavy metals, organic and inorganic dyes and oils. Besides, the newly invented techniques for the characterization of fruit-based biosorbents, the parametric evaluation of biosorbents and their comparison with other available biosorbents are discussed. This review will be helpful for remediating contaminants in wastewater and a panacea for practical engineering solutions.

Abstract	Introduction: The cases of dengue fever have been reported more frequently in Nepal these days. The aim of this study was to find the prevalence of seropositivity among blood samples drawn from suspected dengue cases at a tertiary care centre of Nepal. Methods: A descriptive cross-sectional study was conducted at a tertiary care hospital from 1st June 2017 to 31st October 2018 after getting approval from the Institutional Review Committee (Reference number: 23/2016). A total of 537 suspected dengue patients were selected for the study using convenience sampling. These dengue positive sera were assayed for their reactivity with Immunoglobulin M and Immunoglobulin G present in sera and synthetic peptides of dengue virus by enzyme linked immunosorbent assay. Data was entered and analysed in Microsoft Excel 2016. Point estimate at 95% Confidence Interval was calculated along with frequency, percentage, mean and standard deviation. Results: Among 537 suspected dengue cases, the seropositivity for dengue was found in 124 (23.09%) (19.52-26.65 at 95% Confidence Interval) of the serum. Conclusions: The present study revealed that dengue was more prevalent in our setting compared to similar studies. All the synthetic peptides showed reactivity with dengue-positive sera with maximum reactivity shown by RR2 peptide. In dengue-positive sera, RR2 peptide of dengue virus identified more Immunoglobulin M than Immunoglobulin G.

Abstract	Background: Low back pain due to disc herniation is a common problem causing frequent hospital visits and loss of working days with major socio-economic impact. Conservative treatments like analgesics, physiotherapy do not work in all patients. Surgical treatment has been the mainstay of treatment when indicated but is associated with anesthetic and surgical complications. Intradiscal oxygen-ozone chemonucleolysis is a minimally invasive procedure done under local anesthesia and has promising role in shrinking the bulged disc and reducing nerve root compression and related symptoms. This retrospective study was done to see how intradiscal oxygen-ozone chemonucleolysis reduces pain severity in patients with discogenic low back pain. Methods: Retrospective data were retrieved of those patients who underwent fluoroscopy guided intradiscal oxygen-ozone chemonucleolysis with 5-6 ml of an O2-O3 mixture (concentration of 30 microgram/ml) during a period of two years in Nepal pain care and research center. Numerical pain scale (NRS) at various follow ups were compared to preprocedural NRS. Results: Preprocedural NRS was 8± 13. NRS at three hours, one week, one month, three months and six months were 2± 13 (73 percent reduction), 2± 53 (68 percent reduction), 2± 27 (72 percent reduction), 1± 08 (77 percent reduction) and 1± 67 (79 percent reduction) respectively. Conclusions: Intradiscal oxygen-ozone chemonucleolysis can be a useful modality of treatment for discogenic low back pain in patients who fail to respond to conservative management and in whom surgery is not indicated.

Abstract	In this study, a novel sunlight-active ternary magnetic nano-photocatalyst GCNI (Nanozero valent Iron @ Graphene oxide and Chitosan support) was fabricated. This easily retrievable magnetic nanocomposite was prepared by depositing NZVI (Nano Zero Valent Iron, Fe⁰) over binary GO-CS in seven different compositions for its best optimisation in the solar-light-promoted degradation of RhB. NC (Nano Composite) was characterised by SEM demonstrating their surface morphology. Further characterisation and properties of NC were also studied using XRD, FT-IR, VSM and BET and EDS techniques. The efficacy of the NC was investigated for the removal of RhB in comparison to binary GO-CS and bare NZVI. GCNI 1:1:3 was found to be the best suitable photocatalyst showing synergistic effect in the photodegradation of RhB under given conditions of pH, concentration and time. The mechanism of dye removal and degradation was further discovered by UV-VIS and mass spectroscopy techniques. FT-IR and XRD results of fresh and treated GCNI successively corroborated the mechanism. The sorption kinetics of RhB on to GCNI was found to be described by the pseudo-second-order kinetic equation. The parameters such as dye concentration, pH and the reaction time are varied to understand the effective removal of RhB in wastewater. The outcomes exhibited the highly efficient; up to 99.4% of dye removal, easy magnetic separation of photocatalyst, excellent reusability up-to 87.5% till six consecutive cycles, synergistic effect in adsorption and photo-degradation of dye.

Abstract	Anthropogenic land use and land cover changes are major drivers of environmental degradation and declining soil health across heterogeneous landscapes in Central India. To examines the land cover changes and spatio-temporal variations in forest carbon stock and soil organic carbon (SOC) over the past 25 years in central India. Geospatial techniques, coupled with ground measurements were employed to detect changes in land cover, carbon stocks in vegetation, and soil carbon in various vegetation types. The results indicate that forested areas have decreased, while agriculture and habitation have expanded between 1997 and 2022. Vegetation C stocks varied significantly (P < 0.05) from 39.42 to 139.95 Mg ha

Abstract	Analyzing plant species richness across a broad geographic gradient is critical for understanding the patterns and processes of biodiversity. In view of this, a species richness map was developed by stacking the ranges of 51 tree species along an elevational gradient in the Western Himalaya using stacked species distribution models (SSDMs). Among modeling algorithms available in SSDMs, random forest and artificial neural networks exhibited the best performance (r = 0.81, p < 0.001). The predicted tree species richness distribution pattern revealed a mid-elevation peak at around 2,000 m asl, which is in concordance with the observed richness pattern (R2 = 0.94, p < 0.001). Additionally, structural equation models (SEMs) were used to confirm the key factors that influence tree richness. The results based on SEMs confirm that the elevational pattern of predicted tree species richness is explained by mutual effects of water–energy availability, climate, and habitat heterogeneity. This study also validates that the impact of moisture on tree species richness coincides geographically with climate factors. The results have revealed that water–energy-related variables are likely to impact the species richness directly at higher elevations, whereas the effect is more likely to be tied to moisture at lower elevations. SSDMs provide a good tool to predict a species richness pattern and could help in the conservation and management of high biodiverse areas at different spatial scales. However, more investigation is needed to validate the SSDMs in other parts of the Himalayan region to provide a comprehensive synoptic perspective of Himalayan biodiversity at a larger scale.

Abstract	Understanding patterns in forest communities and its driving factors play a critical role in ecological studies. In view of this, present study attempts to understand the role of environmental and anthropogenic factors towards shaping species diversity and composition along the altitudinal gradient (700–3800 m asl) in Indian western Himalaya. A total of 51 tree species (28 families) were recorded; Pinaceae (5) and Fagaceae (5) were the species rich families. α-diversity indices i.e., Margalef's richness index (R), Shannon index (Hʹ) and Simpson index showed a humped shaped distribution, whereas Evenness index (E) showed an inverted humped shaped distribution along the altitude range. Based on non-metric dimensional scaling (NMDS), four different community types were identified. Redundancy analysis (RDA) revealed a strong relationship of tree species composition with environmental (41.73% variation) and anthropogenic factors (17.35% variation). RDA further indicated that the bulk density (BD), disturbance index (DI), mean diurnal temperature range (Bio2) and solar radiation (SR) are significantly associated with sub-tropical (below 1200 m) and lower temperate forest (1200–1700 m) types. Likewise, soil organic carbon (SOC), precipitation of the driest quarter (Bio17) and pH were significantly associated with upper temperate (1700–2900 m), and subalpine forest composition (>2900 m). Both NMDS classification and RDA ordination clearly demonstrate spatial variability in composition of tree community and environmental properties.
