Bee population decline is associated with various stressors, including exposure to pollutants. Among these, titanium dioxide (TiO), an emerging nanoparticle (NP) pollutant, potentially affects living organisms, including bees. This study evaluates the impact of TiO NPs ingestion (1.

- Implantable cardioverter defibrillators (ICDs) are suggested for patients with deadly heart rhythm issues, but their success can be impacted by socioeconomic and psychological factors.
- A study from 2017-2021 on heart failure patients showed that those with unfavorable economic or psychosocial markers had a higher mortality rate in the first year after receiving an ICD.
- The findings indicate that addressing these socioeconomic and psychosocial issues before implantation is crucial, as they can lead to higher risks and possibly inappropriate use of ICDs.
Food Consumption According to the NOVA Food Classification and Its Relationship with Symptoms of Depression, Anxiety, and Stress in Women.
Nutrients
October 2024
Background/objectives: Depression, anxiety, and stress are highly prevalent mental disorders worldwide, and food consumption can change in individuals with these conditions. We aimed to assess the food consumption of women with depressive symptoms and compare it to a control without symptoms.
Methods: A cross-sectional study was conducted with 96 women, aged 18-59, allocated into two groups: control = 62) or depressive symptoms ( = 34).
Physiological responses of the stingless bee Partamona helleri to oral exposure to three agrochemicals: impact on antioxidant enzymes and hemocyte count.
Environ Sci Pollut Res Int
September 2024
Agrochemicals pose significant threats to the survival of bees, yet the physiological impacts of sublethal doses on stingless bees remain poorly understood. This study investigated the effects of acute oral exposure to three commercial formulations of agrochemicals [CuSO (leaf fertilizer), glyphosate (herbicide), and spinosad (bioinsecticide)] on antioxidant enzymes, malondialdehyde content (MDA), nitric oxide (NO) levels, and total hemocyte count (THC) in the stingless bee Partamona helleri. Foragers were exposed to lethal concentrations aimed to kill 5% (LC) of CuSO (120 μg mL) or spinosad (0.
