Multidrug-resistant bacterial species and their untreatable infections threaten human health worldwide. The four seasons’ essential oils (EOs) of Operculicarya decaryi were investigated against methicillin resistant Staphylococcus aureus MRSA. Limonene was the major component identified in O. decaryi EOs followed by methyl cinnamate. O. decaryi autumn essential oil ( Od ao) has a robust antibacterial effect against MRSA. Camphor, carvone, p -cymen-7-ol, α -terpinen-7-al, cryptone, and caryophyllene oxide were highly correlated to the observed activity. Od ao exhibited a significant wound healing ability and remarkable anti-inflammatory activity in human adult dermal fibroblasts (HDFa) cells inflammatory model. A significant reduction in the microbial counts recovered from the spleens of the groups treated by either Fusidic acid or Od ao in in vivo skin infection murine model was observed. This study is the first record for the phytochemical composition of Od ao and its antimicrobial, anti-inflammatory and wound healing activities, suggesting camphor, carvone, and p -cymen-7-ol as top highly correlated components.

The global shift toward energy sustainability has intensified the need for alternative energy sources to mitigate the environmental impact of fossil fuels, which currently highly contribute toC O 2emissions. Solar energy presents a viable solution, particularly in alignment with the energy strategy, which aims for50 %clean energy adoption. However, despite their potential, solar power systems face challenges such as low conversion efficiency, security vulnerabilities in remote locations, and a lack of autonomous coordination. This study presents a hybrid machine learning (ML) framework that combines K-means clustering with long short-term memory (LSTM) networks. The proposed framework enhances feature extraction by incorporating short-term and long-term consumption trends to improve forecasting accuracy, external influences such as time-of-day and seasonal variations to capture contextual factors affecting energy usage, and anomaly detection to identify abnormal energy consumption patterns. The proposed hybrid K-means-LSTM model demonstrates superior prediction accuracy and effective identification of unusual consumption patterns.

In this study, monthly MACCity emissions inventory data were used for carbon monoxide (CO), nitrogen oxides (NO X ), sulfur dioxide (SO 2 ), non-methane volatile organic compounds (NMVOCs), black carbon (BC), and organic carbon (OC), for nine sectors (residential, energy, industries, transport, ships, waste, agricultural waste, solvents, and agriculture) during the period from 1960 to 2020, over the North African region to examine and analyze its monthly and annual time series. Based on the horizontal distribution of emissions, we identified the points with the highest emissions: Cairo and Alexandria in Egypt, Tripoli in Libya, Tunis in Tunisia, Arzew in Algeria, and Tangier in Morocco. The increase in emissions was associated with the increase in population density and human activities. Cairo station recorded the highest annual average emissions of CO, NO X , SO 2 , BC, and OC, due to the increase in population density and human activities, while Tripoli city recorded the highest rate of NMVOCs emissions, due to the presence of oil ports and the concentration of oil-based industries. The trend analysis showed a positive trend for all emissions at all stations. It was also found that the residential, transportation, industrial, and energy sectors contribute significantly to the total emissions, reaching 94% at all stations. More efforts are needed to reduce pollution levels within large cities, as well as to localize clean energy alternatives.

Treated effluent discharge can significantly alter river water quality by affecting parameters such as pH, turbidity, conductivity, and coliform levels, thereby posing risks to both ecosystems and human health. This study evaluated the impact of effluent discharge from the Wupa Wastewater Treatment Plant Abuja, Nigeria on the water quality of the Wupa River. A refined parametric water quality index was developed to enhance monitoring precision, as traditional indices often lack sensitivity to variations in individual parameters. Water samples were collected during the rainy season’s peak mixing period (June–August) from six stations: the influent (INF), effluent (EFF), the point of discharge (POD), upstream of POD (UPOD), and two downstream locations (1kmPOD and 2kmPOD). The samples were analyzed for physical appearance, pH, temperature, conductivity, turbidity, total coliforms, and fecal coliforms. The parametric index incorporated three components: concentration factor, percentage equivalence, and percentage change, to capture parameter-specific changes. Results revealed distinct spatial variations in water quality across the stations. The INF had poor quality, with turbidity between 203–209NTU, total coliforms up to 6000/100 mL, and fecal coliforms also reaching 6000/100 mL, along with a darkish appearance. The EFF showed improvement, with turbidity reduced to 16–19NTU and total coliforms to 400–2000/100 mL, indicating partial treatment success. The UPOD station showed moderate pollution, with turbidity between 69–94 NTU, total coliforms at 600–3000/100 mL, and fecal coliforms ranging from 880–1600/100 mL. At the POD, contamination intensified: turbidity rose to 84–95 NTU, total coliforms increased to 1750–4500/100 mL, and fecal coliforms to 400–900/100 mL. Further downstream, values remained high—turbidity (80–85 NTU), total coliforms (650–3000/100 mL), and fecal coliforms (700–1220/100 mL). pH remained nearly neutral (6.91–7.65), and temperature ranged from 23.8–28.3 °C. Statistical analysis (ANOVA and t-tests) showed significant differences ( p < 0.05) in conductivity (245–345 µS/cm), turbidity, and all coliform counts across stations, while differences in pH and temperature were not significant. The parametric index further revealed that treated effluent influenced river quality through elevated turbidity, minor pH variations (+2% in June, −2% to −4% in July and August), and significant increases in coliform levels. Temperature at the POD rose by 5%–12% but declined downstream. Conductivity increased at the POD(+15.5% to +23%) and remained elevated downstream. Turbidity also increased at the POD(+21.7% in June) before declining. Total coliforms surged at the POD(+50% to +191.7%), with residual contamination downstream, while fecal coliforms showed mixed patterns. These findings indicate that although some parameters return to near-background levels within 1 km, microbial contamination persists, raising concerns about waterborne diseases and the safety of downstream water use. The study concludes that the parametric water quality index is effective in assessing site-specific impacts of effluent discharge and underscores the urgent need for improved wastewater treatment and ongoing water quality monitoring to protect public health and environmental integrity.

The research describes and explains the critical practices of Arab minority group social workers, who were themselves, or whose nuclear family members were welfare services users in the past. The research derived data from in-depth semi-structured interviews with 17 Arab social workers employed in welfare bureaus in Israel. It was found that most of the participants adopted critical practices to change the professional reality they experienced as service users facing six main players: themselves, service users, their colleagues, management, local and central government. Awareness should be raised concerning the critical contribution of the studied social workers.

Rheumatoid arthritis (RA) has a complex etiology that involves environmental and genetic variables. The identification of new genetic connections contributes to accelerating the development of customized medications to treat or delay the progression of diseases. We aimed to assess the relationship between rheumatoid arthritis susceptibility and genetic variations of the Farnesyl Diphosphate Synthase (FDPS) and methyl CpG binding protein 2 (MECP2) genes. 100 patients with rheumatoid arthritis and 100 healthy control subjects participated in this case-control research. Genetic analyses for single-nucleotide polymorphisms (SNPs) in the FDPS and MeCP2 genes were performed on the patients. In terms of FDPS genetic polymorphisms, the sick group had greater frequencies of the TG and GG genotypes, whereas the control group had a higher frequency of the TT genotype. The CC genotype was more common in the control group, but the TC and TT genotypes were more common in the sick group concerning MECP2 genetic polymorphisms. For rheumatoid arthritis, the FDPS (rs2297480) TT genotype seemed to be protective. An increased risk of rheumatoid arthritis was linked to the MECP2 (rs2734647) TT genotype, but the CC genotype seemed to be protective against the condition.

Stress is known to be a risk factor for deficits in working memory creating profound cognitive disturbances resulting in lingering impairments and losses in social and occupational functioning. Although a body of research has identified mindfulness as a potential means of mitigating deficits in working memory, there is a paucity of studies on the association between mindfulness and deficits in working memory among those who have experienced COVID-19 traumatic stress. This exploratory cross-sectional study sought to examine the mitigating effect of mindfulness on COVID-19 stress impacting working memory. The sample included 484 college students in Israel and the USA. Correlation and multiple regression analyses indicated that COVID-19 stress had a modest, inverse association with both a self-report and task-based indicator of working memory. In separate models predicting the different operationalizations of working memory, results revealed different effects for Israeli and USA students. Mindfulness was significantly associated with task-based but not self-reported working memory. The results offered evidence for a small but significant effect of mindfulness as moderating the impact of COVID-19 stress on working memory deficits. This exploratory, cross-sectional study, used a convenience sample limiting the generalizability and its ability to test causal effects, calling for replication.

Graphene oxide (GO) exhibits unique optical properties, making it highly suitable for a wide range of applications in photonics, sensing, and photocatalysis. This study investigates the optical bandgap and emission behavior of GO synthesized from three biomasses using atmospheric plasma technology. The plasma process was conducted for 5 min with a constant argon flow rate of 15 liters per minute, while the equipment current was maintained at 80 A. UV-Vis Diffuse Reflectance Spectroscopy (DRS) was employed to determine the optical bandgap, while photoluminescence (PL) spectroscopy was used to analyze its emission characteristics. The plasma-synthesized GO exhibited an optical bandgap of 2.01 eV for C-GO, 2.28 eV for P-GO, and 2.30 eV for R-GO and broad photoluminescence with emission centered at 520 nm. Following mechanical treatment, the optical bandgap increases to 3.35, 3.32, and 3.48 eV for Cs-GO, Ps-GO, and Rs-GO, respectively. This combination of optical properties highlights the potential of GO for applications requiring tunable bandgap and fluorescence capabilities.
