Use of drinking tools by wild chimpanzees (Pan troglodytes) and the context in which the tools were used were studied at Bossou, Republic of Guinea, West Africa. During the middle to late dry season and early wet season liquids are available occasionally in the holes of trees. Chimpanzees drank water or sap using a leaf (or fiber) as a sponge or spoon. When the chimpanzees were on the ground, they tended to use one of a few kinds of soft, hairless leaves, if they were available nearby. Females, particularly juveniles and adolescents, were thought to be the main users of the drinking tool. In a few episodes, a tool set was used to procure liquid. Once a chimpanzee used a stick to push a leaf sponge into a water hole and to pull it out from the hole. In addition, three chimpanzees used a pestle to squeeze sap from an oil-palm tree before using a fiber sponge. © 1995 Wiley-Liss, Inc.

Pollution of water bodies and related impacts on aquatic ecosystems and ecosystem services: The case of Ghana's booming 'galamsey' industry.

Galamsey is a Ghanaian jargon from the phrase "gather and sell," coined from how gold was mined with simple tools by natives and sold afterwards. Despite its socio-economic benefits, a significant upsurge in galamsey has been widely associated with significant environmental impacts viz, destruction of aquatic ecosystems and ecosystems services. This paper discuses impacts of galamsey on aquatic ecosystems and ecosystem services using the Driver-Pressure-State-Impact-Response framework in combination with the quantitative defensible impact characterization approach to establish the cause-and-impact relationships between pollutants associated with galamsey, the extent to which aquatic ecosystems and ecosystem services are impacted while answering the questions what is happening to the environment and why it is happening (compilation and analysis of status and trends of key environmental indicators) and what the consequences are for the environment (analysis of impacts of environmental change on ecosystem services).

Addictions seem to be more frequent in atopic dermatitis and psoriasis patients than in the general population. This cross-sectional observational study comparatively evaluated substance-related and behavioural addictions in atopic dermatitis and psoriasis patients and analysed possible addiction patterns. From October 2023 to April 2024, 100 atopic dermatitis and 104 psoriasis patients at a German university hospital completed an anonymous questionnaire, including sociodemographic and health-related parameters, along with validated assessment tools for common addictions (smoking, gambling, alcohol, drugs, food, and internet).

Alcohol use disorder (AUD) is a chronic relapsing brain disorder characterized by an impaired ability to stop or control alcohol consumption despite adverse social, occupational, or health consequences. AUD affects nearly one-third of adults at some point during their lives, with an associated cost of approximately $249 billion annually in the U.S.

Aims: Structured clinical interviewing is considered the gold standard in psychiatric diagnosis. The Diagnostic Assessment Research Tool (DART) is a novel modularized, non-copywritten, semi-structured interview; however, no studies have examined the psychometric properties of its alcohol use disorder (AUD) module. The primary aims of this study were to: (i) validate the factor structure of the DART AUD module and (ii) examine measurement invariance across several key demographic and subgroup factors.

Improper use and harmful effects of nitrite ions pose a significant risk to human health. To address this concern, the use of carbon-based materials for electrochemical sensing is regarded as one of the most promising detection tools for ensuring the quality of drinking water and food products. In this context, we developed laser-ablated graphene electrodes (LAGEs) by direct laser scribing on a polyimide substrate, which were subsequently modified by electrochemical deposition of a redox-active melanin-like film (MeLF/LAGEs).
