The objective of this research was to investigate the phenolic profile and some biological properties of the leaves of Euphorbia bupleuroides subsp. luteola grown wild in Algeria, still unexplored. The leaves were subjected to extraction with 80% MeOH using simple maceration (SM) and ultrasound-assisted maceration (UM) to establish the most efficient conditions for the recovery of phenolic compounds. The study of antioxidant potential suggested that SM and UM extracts displayed a superimposable activity both in the DPPH test and in the reducing power assay. On the other hand, in the Fe2+ chelating activity assay, SM was more active than UM. SM extract prevented damage induced by β-amyloid protein (Aβ) being more effective against ROS generated after treatment with Aβ. In addition, SM exhibited later protection against malondialdehyde. In conclusion, it is possible to state that simple maceration represents an effective technique for the recovery of compounds with antioxidant and neuroprotective properties from E. bupleuroides subsp. luteola leaves.

Food neophobia, the fear of trying new foods, may reduce dietary variety, posing risks for nutritional deficiencies. This study examined the links between food neophobia, dietary quality, and diversity among Turkish young adults. A cross-sectional study with 949 participants (470 males, 479 females) aged 18-35 years used the Food Neophobia Scale (FNS) and a 24-h dietary recall to assess food intake. Dietary diversity score (DDS), food variety score (FVS), mean adequacy ratio (MAR), and healthy eating index (HEI-2015) were calculated. The mean neophobia score was 37.07 ± 12.17, with 13.4% high, 67.9% average, and 18.8% low neophobia. The average neophobia group had higher diet quality scores (MAR, DDS, FVS) than the low and high neophobia groups (p < 0.01). Positive relationships with food neophobia were found for niacin, calcium, zinc, plant protein, and cholesterol (p < 0.05). These findings suggest that food neophobia may affect dietary quality variably, with certain micronutrients positively linked to it.

Urban stormwater management failures lead to floodingg. Potentially toxic elements (PTE) are commonly found in floods exposing population and ecosystems. Flooding is a persistent problem in the city of Hermosillo, Sonora thus PTE concentrations were determined, including threats to receiving ecosystems and population. The PTE concentrations were determined by MP-AES and compared to national and international guidelines. The non-carcinogenic and carcinogenic health risks were evaluated for adults and children following the EPA protocols. Al, Fe and Zn showed the highest concentrations. The concentrations exceeded consulted guideline criteria. PTE groups were identified relating to their sources and origin: (1) Fe, Mn, Ti and Al, (2) Cu, Cd and Cr, (3) Pb, Ni and Zn. Non-carcinogenic health effects and cancer risk were observed in the analyzed floodwater indicating that management measures should be taken to protect the flood-affected population.

Background: Household cleaning agents promote hygiene along with causing respiratory effects, especially pediatric asthma. This systematic review quantified the association between exposure to household cleaning agents and pediatric asthma.

Method: Five databases were searched. Data were analyzed qualitatively and quantitatively. RevMan 5.4 calculated odds ratios (OR) with 95% confidence intervals (CI), and a funnel plot assessed publication bias. The Mixed Methods Appraisal Tool (MMAT) and GRADE framework assessed methodological quality and certainty respectively.

Results: Sixteen studies met the eligibility criteria. Meta-analysis showed a significant association between the use of household cleaning agents and pediatric asthma (OR 2.90 (95% CI: 2.13-3.95; p < 0.01, I² = 98%). Exposure stages also showed significant (p < 0.01) association with household cleaning agents (OR 2.92 (95% CI: 2.12-4.03, I² = 98%). No publication bias or high risk of bias was found.

Conclusion: A strong association between exposure to household cleaning agents and an increased risk of pediatric asthma was found. .

This study presents the results of an environment investigation and monitoring of chlorpyrifos contamination in the vicinity of a pesticide enterprise in East China, focusing on its relation to environmental and human health risks. The impact zone of chlorpyrifos is particularly pronounced within approximately 2 km of the enterprise. The highest levels of outdoor dust were observed in SP1, which is closest to the enterprise. The individual health risk of exposure to chlorpyrifos through different media - such as indoor air, rice, vegetables, drinking water and indoor dust - was assessed following the procedure defined by the USEPA. The non-carcinogenic risks to both adults and children do not exceed the permissible standard of 1, suggesting no non-carcinogenic risks due to chlorpyrifos exposure. However, the average daily dose calculated by exposure assessment model shows that children are exposed to higher doses of chlorpyrifos compared to adults due to their lifestyle habits and play patterns.

 Old age odor is associated with delayed skin renewal and fatty acid oxidation by skin bacteria, potentially causing discomfort and health issues. While previous studies primarily targeted 2-nonenal inhibition, this study examined the antibacterial, antioxidant, biofilm inhibition, SDS-PAGE analysis, and trans-2-nonenal scavenging effects of Leuconostoc mesenteroides THF-10, a lactic acid bacterium isolated from Cucumis melo. The cell-free supernatant inhibited S. epidermidis, S. aureus, and P. aeruginosa, with MIC values of 1.25 mg/mL, which decreased to 0.31, 0.62, and 0.04 mg/mL after ethyl acetate fractionation. THF-10 effectively inhibited biofilm formation and exhibited enhanced antioxidant activity, leading to radical scavenging and a 39% reduction in ROS production at 20 µg/mL. The trans-2-nonenal scavenging assay demonstrated a 73% inhibition rate, with no observed toxicity in HaCaT cells. These findings suggest that L. mesenteroides THF-10 possesses strong antimicrobial and antioxidant properties, supporting its potential for mitigating old age odor.

Previous studies found relationship between fluoride exposure and lipid metabolism. In present study, a cross-sectional study was conducted. Urinary fluoride concentrations and lipid metabolism indicators were tested. Single nucleotide polymorphisms of ATP2B1 were sequenced. The median of urinary fluoride was 1.32 mg/L. Urinary fluoride was positively associated with the decrease in serum ApoA1 (OR = 1.48 [95% CI, 1.27-1.72]), inversely with ApoB elevation (OR = 0.69 [95% CI, 0.59-0.80]). Rs12817819 with carriers of T allele was associated with the decrease in serum ApoA1 (OR = 0.46 [95% CI, 0.26-0.81]), but inversely in rs17249754 with carriers for A allele (OR = 1.48 [95% CI, 1.07-2.06]) and rs7136259 with carriers for T allele (OR = 1.70 [95% CI, 1.22-2.37]). There was an interaction between urinary fluoride which was lower than 0.9 mg/L and rs7136259 for carriers of T allele (OR = 2.67 [95% CI, 1.34-5.31]) in serum ApoA1 decrease. It indicated fluoride exposure might be associated with the alteration of serum ApoA1 and ApoB in adults.

Hurricane Maria devastated Puerto Rico in September 2017. We examined it's impact on physical activity, smoking, and alcohol use. Data was from 2015-2019 Behavioral Risk Factor Surveillance System. Linear probability models and differences-in-differences estimators were used to estimate the effects of Maria on any past 30-day physical activity, smoking, and alcohol use. The sample (N = 19,489) was balanced after matching, with 99.1% Hispanics in both groups. Exposure toMaria was associated with a 3%decrease in the probability of any past 30-day physical activity and a 2.7% increase in the probability of any past 30-day alcohol-drinking. The effects on smoking and binge-drinking were statistically nonsignificant. Hurricane Maria could have discouraged Puerto Ricans' physical activity but nudged alcohol use. Future studies should investigate the sustained impacts of natural disasters on health behaviors and underlying mechanisms. Interventions may be warranted to promote healthy lifestyles among disaster survivors.

Zeolite-based-fertilizers can be obtained by adsorbing plant nutrients to their porous structure. In this research, the natural zeolite (0-200 μm) from Gordes/Türkiye was combined with NH₄NO₃ in a 1:4 solid ratio and processed at 200 °C for 2-24 hours and characterized with diffrent techniques. The optimal synthesis time was 8 hours, yielding a fertilizer with 5.06% nitrogen content. The zeolite-based-fertilizer exhibited a clinoptilolite structure similar to the raw zeolite but demonstrated a greater percentage of mass loss in the DTA/TGA analyses and distinct nitrate peaks in the FTIR spectra, attributable to ammonium nitrate adsorption. The BET results showed a decrease in the BET surface area after the adsorption of NH₄NO₃ onto natural zeolite, with measured values of 34.56 m²/g for natural zeolite and 19.24 m²/g for zeolite-based-fertilizer. The results indicate successful synthesis of a zeolite-based nitrogen fertilizer with potential compatibility with Green Deal goals.  .

The measurement of the concentration of PM2.5 and PM10 pollutants was carried out by means of a device for measuring suspended particles (LowVolume) for 24 hours and during 6 months in the number of 180 samples in industrial and non-industrial areas. The average concentration of PM2.5 and PM10 measured in the air of the industrial area was 29.70 and 56.13 µg/m3, respectively, and in the air of the non-industrial area was 29.40 and 46.15 µg/m3, respectively. The attributed component related to total mortality caused by PM2.5 and PM10 in the industrial area was equal to 17.31% and 14.90% and in the non-industrial area was equal to 17.12% and 11.50%, respectively. The rate of respiratory mortality attributed to PM2.5 and PM10 was 20.98% and 37.26% in the industrial area and 20.75% and 29.74% in the non-industrial area, respectively.   .
