There are many preparations for tobacco use, which can be classified as smoking or smokeless tobacco. Among the noncigarette preparations that produce smoke, we cite cigars, pipes and narghiles. Smokeless tobacco can be found in preparations for chewing or for being absorbed by nasal and oral mucosae (snuff). However, all tobacco products deliver nicotine to the central nervous system and there is a confirmed risk of dependence. In addition, there is no safe form of tobacco use, and tobacco users have a significantly increased risk of morbidity and premature mortality due to tobacco-related diseases.

Synthesis of the photocatalysts with near-infrared light response usually involves upconversion materials or plasmon-assisted noble metals. Herein, NiTiO/TiO was synthesized by using waste tobacco stem-silks as biotemplates and tetra-tert-butyl orthotitanate and nickel nitrate as precursors in a one-pot procedure. NiTiO(1.

Biomass foam with porous structure has broad application prospects in thermal energy management. However, traditional foams can only passively insulate heat, unable to effectively store thermal energy and prolong the insulation time. In this work, microcapsules rich in paraffin were prepared using the Pickering emulsion template method with phosphorylated cellulose nanocrystals (CNC) as an emulsifier.

Background: The increasing prevalence of heated tobacco products (HTPs) has heightened concerns regarding their potential health risks. Previous studies have demonstrated the toxicity of cigarette smoke extract (CSE) from traditional tobacco's mainstream smoke, even after the removal of nicotine and tar. Our study aimed to investigate the cytotoxicity of CSE derived from HTPs and traditional tobacco, with a particular focus on the role of reactive oxygen species (ROS) and intracellular Ca.

Background: Survival rate of patients with oral cancer (OC) remains to be very low despite advancements in therapy and surgical techniques. This is attributed to the fact that most OC cases are discovered at a late stage. Dentists play a vital role in early detection of OC through oral mucosal examination, and in informing the patients about avoidable risk factors of the disease, such as tobacco and excessive alcohol use.
