Control of human mobility is one of the most effective measures to prevent the spread of coronavirus disease 2019 (COVID-19). However, the imposition of emergency restrictions had significant negative impacts on citizens' daily lives. As vaccination progresses, we need to consider more effective measures to control the spread of the infection.

- Lower third molar extraction is a common dental surgery, and while the procedures are routine, their difficulty and associated complications can vary based on individual patient factors.
- A study involving 1,826 extractions in Japan found that the overall prevalence of postoperative complications was 10.0%.
- Key risk factors for complications included older age (over 32 years), radiographic relationships of tooth roots with the mandibular canal, and the depth of tooth impaction, indicating that older patients with deeply impacted teeth may face higher risks after surgery.
Article Synopsis
- A multicenter retrospective study examined 69 patients with mucosal malignant melanoma (MM) of the oral cavity in Japan to analyze demographics and treatment outcomes from 2000 to 2020.
- The study found that most patients were older men, with a mean age of about 70, and many had advanced disease stages, with 79.7% undergoing radical therapy.
- Results indicated that early detection and radical treatment significantly improved survival rates, highlighting advanced T classification as a key prognostic factor for overall survival.

Controlling human mobility is thought to be an effective measure to prevent the spread of the COVID-19 pandemic. This study aims to clarify the human mobility types that impacted the number of COVID-19 cases during the medium-term COVID-19 pandemic in the Osaka metropolitan area. The method used in this study was analysis of the statistical relationship between human mobility changes and the total number of COVID-19 cases after two weeks.

The purpose of the present study was to clarify the relationship between hypertension and morphological changes in the submandibular glands.
Materials And Methods: An epidemiological study was conducted to elucidate the relationship between hypertension and dry mouth.
We compared the characteristics of seeds within faeces between semi-terrestrial Japanese macaques (Macaca fuscata) and sympatric arboreal Japanese martens (Martes melampus) in Shiga Heights, central Japan. We collected faecal samples of the two mammalian species for 1 year (n = 229 for macaques and n = 22 for martens). We then compared the proportion of seed occurrence, life-form composition, number of seeds and species richness within single faecal samples, and the seed intact ratio between the two mammalian species.
