With the emergence of COVID-19 variants and new viruses, it remains uncertain when the next pandemic will occur. A lockdown is considered the last resort to halt the spread of infection; however, it causes significant economic and social damage. Therefore, exploring less harmful alternatives during such scenarios is crucial.

Pokkah Boeng disease has been observed in nearly all countries where sugarcane is commercially cultivated. The disease was considered a minor concern in earlier times, but due to climate change, it has now become a major issue. It is caused by fungi, specifically the fungal complex.

Health care workers are at risk of infection from aerosolization of respiratory secretions, droplet and contact spread. This has gained great importance after the COVID19 pandemic. Intra-operative aerosol-generating procedures are arguably unavoidable in the routine provision of thoracic anesthesia.

Dental operations inherently involve a high risk of airborne cross-infection among medical staff and patients due to the exposure of respiratory secretions, which contain pathogenic microorganisms and typically spread in the form of aerosols. In order to contribute to the understanding of aerosol dynamics during dental operation and efficiently mitigate their dispersion and deposition through appropriate ventilation, 3D numerical simulations and full-scale experimental measurements were performed in this study. The indoor airflow distribution and dynamic aerosol behaviors observed under three optimized ventilation schemes (Scenario I-III) were compared with those observed under the current ventilation system.

Article Synopsis
- SARS-CoV-2 can infect liver cells (hepatocytes), leading to elevated liver enzymes and more severe disease in those with pre-existing liver conditions.
- The study shows that the virus replicates and spreads in hepatocytes, with infection being dependent on two specific proteins, ACE2 and TMPRSS2, which are found on the liver cells.
- Infection causes rapid liver cell death, with the Omicron variant causing quicker but less extensive damage compared to other strains, as seen in both human liver cells and infected mice.
