miR-27b targets MAIP1 to mediate lipid accumulation in cultured human and mouse hepatic cells.

Non-alcoholic liver disease (NAFLD) is a condition caused by excessive fat accumulation in the liver and developed via multiple pathways. miR-27b has been suggested to play crucial roles in the development of NAFLD, assuming via targeting genes involved in lipid catabolism and anabolism. However, other pathways regulated by miR-27b are largely unknown.

Outcomes of a telemedicine smoking cessation programme for heated tobacco product users in Japan: a retrospective cohort study.

Objectives: Japan is one of the largest markets for heated tobacco products (HTPs), and the number of HTP users, including dual users, is growing. However, it is not yet clear whether a telemedicine smoking cessation programme is effective for nicotine-dependent HTP users to quit smoking. We assessed the outcomes of a telemedicine smoking cessation programme in terms of continuous smoking cessation among smokers who had used HTPs compared with those who used exclusively cigarettes.

[Secondhand smoke exposure in a car].

Objective: The Health Promotion Act was revised in 2018 and prohibits smoking inside taxis and buses. However, there is no regulation for smoking in the business vehicles of companies or private cars. This paper examined exposure to secondhand smoke in vehicles with digital dust monitors.

Secondhand Smoke from a Veranda Spreading to Neighboring Households.

Secondhand smoke (SHS) caused by smoking on apartment verandas is a severe social problem in Japan. If someone smokes on a veranda, SHS drifts into other residents' rooms through their windows. Most non-smoking residents are annoyed by this, but they do not confront the person responsible.

Synthesis of 6-substituted 2-phenacylpyridines from 2-(phenylethynyl)pyridine via isoxazolo[2,3-a]pyridinium salt.

When 2-(phenylethynyl)pyridine was oxidized, the formed N-oxide immediately cyclized at the ethynyl group to form isoxazolo[2,3-a]pyridinium salt. This salt underwent Reissert-Henze-type reactions with alcohol in the presence of a base to afford 6-substituted 2-phenacylpyridines, which are not easily synthesized through alternative procedures. When acetonitrile was used as a solvent, an amide functional group was introduced into the phenacylpyridine framework.

[Shock absorption of mouthguard materials--influence of temperature conditions and shore hardness on shock absorption].

Purpose: To consider changes in the physical properties of mouthguard materials with the change of temperature, shock-absorbing examination and Shore hardness measurement of existing MG materials and other elastic materials were carried out.

Methods: Both examinations were done under two temperature conditions: at room temperature (25 degrees C) and simulated intraoral temperature (37 degrees C). In addition, a comparative study of the relation between Shore hardness and shock absorption of the materials was made.
