Seven funeral homes were surveyed in 1980 to determine the magnitude of embalmers' exposure to formaldehyde, other chemical vapors, and total and respirable particulates. Air was monitored for formaldehyde by personal and area samples, and assayed using the chromotropic acid method. Personal sampling revealed time-weighted average formaldehyde concentrations which ranged from 0.1 to 0.4 ppm (mean 0.3 ppm) and 0.5 to 1.2 ppm (mean 0.9 ppm) during the embalming of intact and autopsied bodies, respectively. Concentrations of other airborne chemicals and of particulates were negligible. In preparing autopsied bodies, embalming technique and condition of the body itself appeared to be major determinants of formaldehyde exposure.

Photocatalytic reduction of nitrate to N holds great significance for environmental governance. However, the selectivity of nitrate reduction to N is influenced by sacrificial agents and the kinds of cocatalysts (such as Pt and Ag). The presence of unconsumed sacrificial agents can aggravate environmental pollution, while noble metal-based cocatalysts increase application costs.

Aims: This study aimed to evaluate the enamel remineralization effect of fluoride-incorporated bioactive glass (F-BG) toothpaste on artificial subsurface caries in primary teeth.
Materials And Methods: Forty sound primary maxillary incisors were subjected to a demineralizing solution for four days to induce artificial enamel caries. The teeth were randomly divided into four experimental groups ( = 10 per group): Group I, F-BG toothpaste (530 ppm fluoride) (BiominF); Group II, 0.

Background: Importance of fluoride in dental restorative materials for preventing secondary caries. Several commercially available tooth-colored dental restorative materials, such as glass ionomer cement, resin composites, and compomers were used for this study.
Aim: To evaluate the amount of fluoride release from tooth-colored restorative materials [Conventional Glass Ionomer Cement (GC Fuji II)], Resin-modified Glass Ionomer Cement (ACTIVA BioACTIVE-RESTORATIVE), and Giomer (BEAUTIFIL II LS)] using ion-selective electrode (ISE) and spectrophotometer using zirconyl alizarin red dye method.

Polysorbates, in particular polysorbate (PS) 20 and 80, are the most commonly used surfactants for stabilising biotherapeutics produced by biotechnological processes. PSs are derived from ethoxylated sorbitan (a derivative of sorbitol) esterified with fatty acids of varying chain length and degree of saturation. In the past, these surfactants have been reported to have specific liabilities.

Background: Right ventricular (RV) pacing exacerbates heart failure and increases cardiac mortality in patients with reduced ejection fraction (EF). However, its impact on left ventricular dysfunction in patients with preserved EF remains inconclusive. This study investigates the relationship between RV pacing, global longitudinal strain (GLS), and EF in patients with preserved EF.
