Currently, there are limited treatment options available for the monkeypox disease. We used a computational strategy to design a specific antigenic vaccine against pathogens. After using various immunoinformatic tools and filters, cytotoxic T-cell lymphocyte (CTL)-, helper T-cell lymphocyte (HTL)-, and interferon gamma (IFN-γ)-inducing epitopes, which comprised the vaccine, in addition to other parameters, such as antigenic and allergic profiles, were assessed to confirm the safety of the vaccine. However, vaccine interaction and stability with Toll-like receptors (TLRs) were assessed by dynamic simulation methods, and it was found that the constructed vaccine was stable. In addition, C-IMMSIM tools were used to determine the immune-response-triggering capabilities of the vaccine. These immunoinformatic findings reveal that constructed vaccine candidates may be capable of triggering an efficient immune response for monkeypox viral infections. However, experimental evaluation is required to verify the safety and immunogenic profile of constructed vaccines.

Objective: To determine the drug utilization pattern of antihyperglycemic agents (AHA) in a tertiary care teaching hospital. Materials and Methods: This was a prospective observational study. All the relevant data were collected and drug utilization pattern of AHA was determined. Direct cost associated with the use of antihyperglycemic medicines was calculated and consumption of the antihyperglycemic medicines was measured as defined daily dose (DDD)/100 bed-days. The adverse drug reactions (ADRs) related to anti-diabetic medicines were monitored. Statistical Analysis Used: Chi square test (χ² ), mean±standard deviation. Results: During the study period, 350 patients diagnosed as diabetes mellitus (DM) were admitted. Insulin was prescribed as monotherapy to 81% and to 52% patients during hospital stay and discharge, respectively. Increase in utilization of insulin was recorded in majority of the patients due to presence of co-morbid conditions or resistance to oral hypoglycemic drugs. Use of insulin at the time of discharge decreased significantly (P<0.05) by 29%. Among the oral AHA, combination of glimepiride with metformin was more prevalent during hospital stay and at the time of discharge monotherapy of metformin followed by glimepiride was more prevalent. During hospital stay, cost of AHA was found to be Rs. 95.27 ± 119.03. The total antihyperglycemic drug consumption in the medicine ward during study period was 13.42 DDD/100 bed-days. Fifty ADRs were reported and descriptions of ADRs were found to be only hypoglycemia. Conclusion: The study exhibited a significant increase in the utilization of two drug combination therapies and monotherapy of oral AHA and decrease in the utilization of insulin at the time of discharge.

Octocrylene is a widely used ingredient in sunscreen products, and it has been observed that the use of sunscreen has been increasing over the last few decades. In this paper, we investigated the way in which sunscreen’s ingredient octocrylene may disrupt normal vitamin D synthesis pathway, resulting in an imbalance in vitamin D levels in the body. The key techniques used for this insilico investigation were molecular docking, molecular dynamic (MD) simulation, and MMPBSA-based assessment. Vitamin D abnormalities have become very common in human health. Unknown exposure to chemicals may be one of the important risk factors. In molecular docking analysis, octocrylene exhibited a binding energy of −11.52 kcal/mol with vitamin D binding protein (1KXP) and −11.71 for the calcitriol native ligand. Octocrylene had a binding potency of −11.152 kcal/mol with the vitamin D receptor (1DB1), and calcitriol had a binding potency of −8.73 kcal/mol. In addition, octocrylene has shown binding energy of −8.96 kcal/mol with CYP2R1, and the calcitriol binding energy was −10.36 kcal/mol. Regarding stability, the root-mean-square deviation (RMSD), the root-mean-square fluctuation (RMSF), the radius of gyration, hydrogen bonding, and the solvent-accessible surface area (SASA) exhibited that octocrylene has a stable binding pattern similar to calcitriol. These findings revealed that incessant exposure to octocrylene may disrupt normal vitamin D synthesis.

Widespread application of hexaconazole for agriculture purpose poses a threat to human health by disrupting normal endocrine homeostasis. To avoid adverse health effects on human, it is crucial to identify the effects of hexaconazole on key enzymes responsible for steroidal hormone synthesis. In view of this, present study was conducted to investigate the interaction mechanisms of hexaconazole with key enzymes in comparison with their food drug administration (FDA) approved inhibitor by molecular docking and molecular dynamics simulations. Results indicate that hexaconazole contacts with the active site of the key enzymes required for steroidal hormonal synthesis. Results pertaining to root-mean-square deviation, root-mean-square calculation, radius of gyration, hydrogen bonding and solvent accessible surface area exhibited that the interaction pattern and stability of interaction of hexaconazole was similar to enzyme specific inhibitor. In addition, ligand and enzyme complex interaction energy of hexaconazole was almost similar to key enzyme and FDA-approved enzyme specific inhibitor complex. This study offers a molecular level of understanding of hexaconazole with different enzymes required for steroidal hormonal synthesis. Findings of the study clearly suggest that hexaconazole has efficacy to stably interact with various enzyme required to progress the pathway of hormonal synthesis. If incessant exposure of hexaconazole occurs during agricultural work it may lead to ravage hormonal synthesis or potent endocrine disruption. The result of binding energy and complex interaction energy is depicted in the graphical
