Several parameters can delay the first arrival of flies on a corpse and the subsequent development of the larvae. This study focuses on the development of Lucilia sericata (Diptera: Calliphoridae) (Meigen, 1826) on household chemical-contaminated substrates. bleach, perfume, hydrochloric acid, caustic soda, insecticide, mosquito repellent, and gasoline in quantities consistent with an amount that could possibly be spilled on a corpse were mixed with beef liver to simulate contaminated fleshes. Larvae were bred at 25 °C on these media until emergence. Four developmental parameters were followed: survival rates, development times, sex ratios, and adult sizes. Hydrochloric acid, insecticide, and gasoline killed all larvae. In low quantities, caustic soda and mosquito repellent increased the development time and decreased the adult size. However, high quantities of these chemicals killed all larvae. Lastly, bleach and perfume did not affect the survival rate and barely impacted the development time or adult size. These results demonstrate common household products spilled on a corpse can strongly affect the development of Calliphoridae larvae. The effects of such products should be considered in forensic entomology cases.

Acne vulgaris affects approximately 80% of young adults and adolescents in the world. Acne presents as comedones, pustules, papules, and nodules on the face, chest, shoulders, or back. It can lead to a significant decrease in quality of life with a high risk of associated depression and anxiety.

While there are a plethora of cosmeceutical peptides, few combine anti-aging and anti-inflammatory benefits with small size.
Methods: Preclinical and clinical studies evaluated the anti-inflammatory properties, anti-aging benefits, and tolerability of acetyl dipeptide-31 amide (AP31), a novel, small, anti-aging micropeptide, to understand its impact as a multifaceted, cosmetic, anti-aging, and anti-inflammaging ingredient.

Background: Acne is prevalent in approximately 80% of individuals aged 11 to 30 years, with scarring occurring in about 40% of cases. Early and sustained treatment is crucial for preventing acne scarring, regardless of severity.
Objectives: The objective of this study was to evaluate skin tolerability and patient compliance after combining a specific dermatologic routine with pharmacological therapy in patients affected by different degrees of acne.

Gel coating films comprising nanodiamonds organo-modified with 12-hydroxystearic (12-OHC ) and stearic acids were prepared and characterized. Because molecules with 12-OHC groups can convert solvents into thixotropic gels, Gemini-type diamide derivatives with two 12-OHC chains were also introduced as thixotropic additives into the gel coating films. Although the 12-OHC -modified nanodiamonds did not lead to solvent gelation on their own, they displayed an affinity for the thixotropic additive molecules.

Introduction: Sales of oral nicotine pouches (ONPs), including brands such as Zyn, on!, Velo, and Rogue, have risen precipitously in the US. One potential driver of ONP use may be exposure to the products and their marketing in local tobacco retailers. This study examines the prevalence and correlates of ONP availability in a large, representative sample of tobacco retailers in three major US cities.
