    Abstract Chikungunya fever is a mosquito-borne disease caused by the chikungunya virus (CHIKV) and has drawn substantial attention in recent years. So far, no effective treatment is available in the form of drugs or vaccines. In this study, we aimed to screen some drugs against the pathogenic Chikungunya virus through a molecular docking approach. As a fact, the spike E2 protein plays an important role in viral attachment to the human host cell, binding to a cell receptor MXRA8. The molecules screened for in-silico interaction against MXRA8 were selected with top hit based on binding affinity. The existing intermolecular bonds were investigated further in the active site of the protein that interacts with the top-hit ligands. Gambogic acid (guttic acid) was depicted as the furthermost potential inhibitor when compared to the others it had the lowest binding affinity (-10.9 kcal/mol). Gambogic acid, as a potential antiviral agent against the spike E2 protein, could be a promising candidate.

    Abstract Use of non-steroidal anti-inflammatory drugs (NSAIDs) is one of the leading causes of gastric ulcers. Excellent therapeutic properties have made the use of NSAIDs widespread. Nano-drug delivery to reduce systemic toxicity through modulating drug pharmacokinetics may be a better choice. Presently, we investigated if naproxen nanoformulation (PVA capped NPRS-MgO NPs) is less toxic to be used as an alternative drug. Groups of mice were assigned to control, NPRS-treated, CNF-treated, UNF-treated, and MgO NPs-treated groups. Analyses included gross examination of gastric mucosa, calculation of ulcer and inhibition indices, determination of tissue levels of reactive oxygen species (ROS), malondialdehyde (MDA), catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), and reduced glutathione (GSH), histological and immunohistochemical assessment of i-NOS, COX-2, and caspase-3 of stomach mucosa, q-PCR for the detection of mRNA expression of IL-1β, IL-6, and TNF-α. Results were compared statistically at P < 0.05. Compared to NPRS-treated mice which developed multiple ulcers, had elevated MDA and ROS levels, and deceased CAT, POD, SOD, and GSH levels, significantly increased expression of IL-1β, IL-6, and TNF-α mRNA, damaged surface epithelium with disrupted glandular architecture and leucocyte infiltration of lamina propria with a marked increase in mucosal COX-2, i-NOS, and caspase-3 expression, oral administration of coated and uncoated naproxen nanoformulations prevented the gross mucosal damage by a restoration of all biochemical, histological, and immunohistochemical alterations to near control levels. The present study demonstrates that naproxen sodium nanoformulation has a gastroprotective action and in the clinical setting can be a better alternative to conventional naproxen.

    Abstract Lately, organizations are giving attention to enhancing employee resilience due to turbulent economic times caused by lockdowns in the last couple of years. This explanatory research proposes and tests the mediating role of employee resilience to link task challenge and employee performance during the COVID-19 pandemic in government schools of Oman using the broaden-and-build theory. An explanatory research design was used for this empirical study. An Arabic-translated questionnaire version was designed to collect primary data online during the lockdown using simple random sampling. We used the Preacher and Hayes macro to analyze moderated mediation using cross-sectional data and analyzed 441 responses. The findings confirm the mediation roles of employee resilience and moderating roles of digitalization during unusual circumstances. The study has implications for the school administrators, Omani policymakers and schooling staff of the Middle Eastern educational industry.

    Abstract Arsenic (As) traces have been reported worldwide in vegetables and crops cultivated in As-polluted soils. Being carcinogenic, the presence of As in edibles is of great concern as it ultimately reaches humans and animals through the food chain. Besides, As toxicity adversely affects the growth, physiology, metabolism, and productivity of crops. In the present study, Trigonella foenum-graecum (Fenugreek) was exposed to the As stress (0, 50, 100, and 150 μM sodium arsenate) for a week. Further, evaluation of As accumulation in roots and shoots, magnitude and visualization of oxyradicals, and thiol-based defence offered by Fenugreek was assessed.

    Abstract Arsenic (As) traces have been reported worldwide in vegetables and crops cultivated in As-polluted soils. Being carcinogenic, the presence of As in edibles is of great concern as it ultimately reaches humans and animals through the food chain. Besides, As toxicity adversely affects the growth, physiology, metabolism, and productivity of crops. In the present study, Trigonella foenum-graecum (Fenugreek) was exposed to the As stress (0, 50, 100, and 150 μM sodium arsenate) for a week. Further, evaluation of As accumulation in roots and shoots, magnitude and visualization of oxyradicals, and thiol-based defence offered by Fenugreek was assessed. The root and leaf accumulated 258–453 μg g⁻¹ dry wt (DW) and 81.4–102.1 μg g⁻¹ DW of As, respectively. An arsenic-mediated decline in the growth index and increase in oxidative stress was noted. Arsenic stress modulated the content of thiol compounds; especially cysteine content increased from 0.36 to 0.43 µmole g⁻¹ FW protein was noted. Random Amplified Polymorphic DNA (RAPD)–based analysis showed DNA damage in As-treated plants. Health risk assessment parameters showed that As concentration in the consumable plant shoot was below the critical hazard level (hazard quotient < 1). Moreover, T. foenum-graecum showed varied responses to As-induced oxidative stress with applied concentrations (150 μM being more toxic than lower concentrations). In addition, the RAPD profile and level of thiol compounds were proved significant biomarkers to assess the As toxicity in plants. The conclusion of this study will help users of fenugreek to have a clue and create awareness regarding the consumption.

    Abstract Objective: This study aimed at recording therapeutic plant species used by inhabitants to treat dental disorders in the district of North Waziristan, Pakistan. The indigenous people of the studied area are dependent on medicinal plants for their basic health care needs including dental care.
    Methods: Ethnomedicinal data were collected using a semi-structured questionnaires, and in addition 130 local informants were interviewed. The collected data were evaluated using various quantitative indices, including use value (UV), relative frequency of citation (RFC), fidelity level (FL%), and Jaccard Index (JI).
    Results: A total of 69 plants belonging to 48 plant families used in dental disorders were identified. The Lamiaceae was the leading family that shared 7 species, followed by Solanaceae (4 spp).The dominant life form used was herbs (47.83%), folowed by leaves (43.90%) in preparing remedies for different dental disorders. Decoction was the most common mode of preparation (34.21%), followed by pastes (21.05%). The highest RFC (0.36) was reported for Bergenia ciliata, followed by Salvadora oleoides (0.35). The majority of the plants (36 spp) were utilised as herbal medicine to treat toothache, followed by 13 species for periodontal (gum) infections, 11 species used for teeth cleaning, and 9 species for halitosis (bad breath).
    Conclusions: This study is the first-ever record of ethnomedicinal applications for the treatment of dental diseases from Pakistan. Some of the forgeoing hebal medications should be further evalauted for the development of pahrmaceutical bio-products for the treatment of dental disorders.
