Food emulsifiers aggravate inflammation and oxidative stress induced by food contaminants in zebrafish.

Food emulsifiers like glycerol monostearate (G) and Tween 80 (TW) are commonly used to help formation and maintain stability of emulsions. However, certain food contaminants and emulsifiers often co-occur in the same food item due to food culture and cooking methods. For this reason, the present study investigated interaction of toxic effect of emulsifiers (G and TW) and process contaminants (acrylamide (AA) and benzo [a]pyrene (BAP)) on zebrafish.

Avoiding the needle: A quality improvement program introducing apixaban for extended thromboprophylaxis after major gynecologic cancer surgery.

Objective: Patients undergoing gynecologic cancer surgery at our centre are recommended up to 28 days of enoxaparin for extended post-operative thromboprophylaxis (EP). Baseline survey revealed 92% patient adherence, but highlighted negative effects on patient experience due to the injectable route of administration. We aimed to improve patient experience by reducing pain and bruising by 50%, increasing adherence by 5%, and reducing out-of-pocket cost after introducing apixaban as an oral alternative for EP.

Ecotoxicological risk of asphalt pavements to aquatic animals associated with pollutant leaching.

Contaminants such as heavy metals and polycyclic aromatic hydrocarbons (PAHs) can be released from asphalt pavement and transported through stormwater runoff to nearby water bodies, leading to water pollution and potential harm to living aquatic animals.

Artificial runoffs were prepared in the laboratory concerning the effects of water, temperature, and traffic.

Mating environments mediate the evolution of behavioral isolation during ecological speciation.

The evolution of behavioral isolation is often the first step toward speciation. While past studies show that behavioral isolation will sometimes evolve as a by-product of divergent ecological selection, we lack a more nuanced understanding of factors that may promote or hamper its evolution. The environment in which mating occurs may be important in mediating whether behavioral isolation evolves for two reasons.

Food emulsifiers increase toxicity of food contaminants in three human GI tract cell lines.

Food products simultaneously containing both food contaminants and emulsifiers are common in baked products, coffee and chocolate. Little is known regarding how food contaminants and emulsifiers interact and alter toxicity. Recent studies have shown that while emulsifiers themselves have little toxicity, they could cause changes in the gut microenvironment and lead to issues such as increased uptake of allergens.
