Non-hazardous waste generated in Metropolitan Lima and Callao is transported to the Modelo Callao landfill for safe disposal. The accumulation of waste constitutes a significant source of fungal particles released into the atmosphere, posing a potential health risk to nearby populations. The aim of this research was to evaluate the concentration of outdoor fungal particles, considering environmental conditions (temperature, relative humidity, wind speed, and direction) during summer and winter seasons in the 18 de octubre settlement and Chillón Avenue, areas located in the vicinity of the Modelo Callao Landfill in Ventanilla during 2022.

Myeloid-derived suppressor cells (MDSC) are considered an aberrant population of immature myeloid cells that have attracted considerable attention in recent years due to their potent immunosuppressive activity. These cells are typically absent or present in very low numbers in healthy individuals but become abundant under pathological conditions such as chronic infection, chronic inflammation and cancer. The immunosuppressive activity of MDSC helps to control excessive immune responses that might otherwise lead to tissue damage.

- Insomnia is common in individuals with Autism Spectrum Disorder (ASD), and recent studies indicate that sleep problems may be more severe in females with ASD compared to males.
- The study utilized a Shank3 mouse model to examine sex-specific sleep differences through polysomnography, focusing on baseline sleep patterns and responses to sleep deprivation.
- Results revealed distinct sleep behaviors between male and female Shank3 mice, with males showing less sleep during their active phase and females displaying altered sleep patterns, highlighting how sex and genetic factors can influence sleep in ASD.
Article Synopsis
- * Disrupting lipid rafts, which are involved in the bacteria's entry into cells, can reduce S. aureus internalization, offering a potential strategy to improve treatment effectiveness.
- * The study identified alpha-hemolysin (Hla) as a key factor needed for the bacteria to enter lung cells, with caveolin-1 playing a critical role as a receptor for this process, underscoring the significance of lipid rafts in bacterial invasion.
Article Synopsis
- Olive leaves, a byproduct of olive oil production, are being repurposed for extracting beneficial substances like phenolic compounds.
- A study focused on extracting polyphenolic compounds using potassium hydroxide (KOH) from these leaves, which resulted in high concentrations of hydroxytyrosol.
- The extract not only enhanced the color and potassium content of black olives but also reduced acrylamide formation by up to 32%, showing potential for healthier olive products.
