An Efficacy of Covid – 19 Pandemic: Recovery of Workplace Environment and Ecosystem

The Covid-19 pandemic started in the late December 2019 and is still progressing globally at a rapid rate. The easy spreading nature of the covid-19 causative virus has made most of the countries to implement complete lockdown. The lockdown measure taken by most countries to combat the disease has not only assisted in decreasing the rate of spread but also the pollution of the workplace environment and environment as a whole. In the absence of most human and industrial activities that cause pollution, the nature is on its way in purifying itself. Without human intervention, the pollution free environment and its interaction with the ecosystem is bouncing back at a faster pace. The article explained the impact of lockdown measures on the reduction of environmental pollution on a global scenario.

Post-Covid Workplace Scenario – Employer and Employee Health and Safety

The decreasing trend in the spread of the covid-19 infection has relaxed the restrictions imposed on the community, especially the working people. This working community, whether or not infected by the virus is now slowly turning back to work, along with the impacts of the lockdown. Though there is a decrease in the infection rate, there is always the possibility of infection at the workplace, as some percentage of the vaccinated people are also getting infected. It is absolutely necessary to follow the covid precautionary measures. Hence, it cannot be said that the normal situation has returned. The employer is in a state to manage a crowd comprising post-covid patients, caretakers of covid patients and non-affected groups. The literature works reporting on post covid scenario, precautionary measures to be taken and workplace, benefits of workplace social distancing and sanitation, and medical care needed for workers were reviewed. This paper discusses the post-pandemic workplace scenario, health and safety, sanitation among workers, awareness of precautionary measures and their behavioral changes

Endodontic treatment of trauma-induced necrotic immature teeth using a tricalcium silicate-based bioactive cement : a report of 3 cases with 24-month follow-up

Background: Pulp necrosis is the second most common complication after traumatic dental injuries and occurs mostly within the first 6-24 months of follow-up period, depending on the type of dental trauma. Case report: Three cases with endodontic treatment scenarios of trauma-induced necrosis in immature permanent anterior teeth. All cases were treated by full canal obturation with Biodentine (Septodont, Saint Maur des Fosses, France) and documented for a follow-up period of 24 months. Conclusion: Copious irrigation of the root canal, minimal mechanical preparation, use of calcium hydroxide for a short period of time and complete obturation of these immature teeth with a bioactive cement with superior mechanical properties such as Biodentine were the prominent reasons attributed to the success of these three cases

The need for assessing mental health literacy among teachers: an overview

Background: The magnitude of mental disorders is a growing public health concern. According to World Health Organization (WHO) reports, one out of five children suffer from a disabling mental illness. Majority of mental illnesses start during the adolescent period. Management of mental illnesses start from recognizing the needy adolescent and providing appropriate therapy and support. Most of the children and adolescents are students who spend almost half of their active time in schools under observation of their teachers. Teachers interact with students daily and can spot the changes in their behavior before they develop full-blown symptoms. Hence, teachers can be a major resource of importance in providing basic mental health services. The teacher’s ability to identify the early signs of mental illness in adolescent students can be considered as the most critical and neglected area. Majority of the studies are conducted in the community or adolescent students and much less attention has been paid to the mental health literacy of educators, who are important role models and youth influencers in addressing mental health literacy. The scenario in India in this regard is highly disappointing with few studies done among teachers

RECENT ADVANCES IN BIOMIMETIC MATERIAL SYNTHESIS

Recent development in the bioinspired materials and biomimetic material synthesis gained more interest and attention. Biomimetic material synthesis can be achieved either by mimicking the organisms that employ biological processes to produce materials or substances. Biomimetic synthesis requires complete understanding of interactions behind the inorganics and organics. In this review, I describe the current progress in biomimetic synthesis in both experimental and simulations mode and classify this information in following perspectives: biomimetic system with template; progress in molecular simulations; materials development based on simulation; intelligent biomimetic system; and bioinspired systems. In addition, synthesis, simulations, principles and relationships are discussed, and the challenges and directions for further development are considered

Correlation between Dermatoglyphics, Dental Caries and Salivary pH: An Invivo Study

BACKGROUND: Dermatoglyphic patterns that are often utilized in judicial and legal investigations are valuable in diagnosis of many diseases related to genetic disorders. Caries, being infectious in origin, might be related to genetics as well. Hence, these patterns are of significance in predicting caries development.MATERIALS AND METHODS: DMFT (decayed, missing, filled teeth) score of 300 female subjects within the age group 0f 18-25 years were recorded and accordingly divided into 3 groups of 100 each; group 1 (DMFT score=0), group 2 (DMFT score < 5) and group 3 (DMFT score ≥ 5). Dermatoglyphic patterns were recorded using Cummins and Midlo method. pH meter was used for recording salivary pH accurately. Fingerprint patterns and salivary pH recorded were correlated with DMFT scores of subject and control groups. Statistical analysis was performed using ANOVA and Chi-square tests (P < 0.05).RESULTS: The mean salivary pH was least in group 3. The predominant dermatoglyphic pattern observed in groups 1 and 2 was loop pattern whereas, in group 3, whorl pattern was predominant. The TFRC (total finger ridge count) was higher in group 3 compared to the other two groups.CONCLUSION: Caries-free people showed inflated frequency of loops, whereas subjects with high decay score had additional share of whorls. The TFRC was higher in individuals with high DMFT score, and salivary pH was inversely proportional to the DMFT score.

MOLECULAR SIMULATIONS OF ORGANIC-INORGANIC INTERFACE

Recent interest in biomolecule adsorption tomaterial surface has grown rapidly, but little is understood at this time regarding specific recognition happens and how to design surfaces to control protein adsorption behavior. Molecular dynamics simulation methods have enormous potential to address this problem by providing an approach to directly investigate the adsorption behavior of biomolecules at the atomic level. The simulation methods should be accurately applied to get meaningful data and the crucial parameters are validated force field, solvation effects, and sampling. In this short review, I address each one and the future directions of this field
