This study examined the possible effects of banana cultivation on phytoplankton biomass and community structure in southwest China along the Lancang-Mekong River. Water and phytoplankton samples were collected on March (dry season) and August (rainy season), and physical-chemical properties of water, phytoplankton biomass and community structure were determined. The results indicated that the banana cultivation resulted in increases in sediment, total phosphorus (TP) and total nitrogen (TN) concentrations at estuaries of Lancang-Mekong River branches. Cultivation decreased phytoplankton diversity, abundance and biomass, as well as changed the phytoplankton community structure at estuaries of branches. Sediment concentration (increased by cultivation) was considered as the dominant influence factor of phytoplankton biomass and community structure. However, at downstream sites (primary channel), banana cultivation did not cause (result from its huge flow) the significant changes in physical-chemical properties of water, phytoplankton biomass or community structure.

Social media-based Health Education plus Exercise Program (SHEEP) to improve muscle function among young-old adults with possible sarcopenia in the community: A feasibility study protocol.

Background: Despite the comparatively high prevalence of possible sarcopenia among young-old adults in the community, there is currently no available and effective social media-based intervention to increase the awareness and change the behavior of the target population to prevent sarcopenia. Using co-design methodology, we developed a multicomponent intervention strategy of health education and exercise for sarcopenia prevention utilizing the TikTok platform.
Objectives: The primary purpose of this study is to examine the feasibility and acceptability of the social media-based intervention to enhance muscle function in community-dwelling young-old adults with possible sarcopenia.

In recent years, Ugandan universities have faced a rising incidence of mental health issues among students, with prevalence rates of mental disorders reaching up to 60% among undergraduates. These challenges significantly impact both academic performance and social interactions. This study aimed to investigate the coping mechanisms among students with mental disorders at Busitema University.

The Ultra-Orthodox (Haredi) Jewish Community in New York City suffered significantly during the COVID-19 pandemic. The community came under public scrutiny after some members staunchly advocated for reopening of certain resources central to community culture. This study utilizes qualitative techniques to examine the perspectives of medical providers that serve the Haredi community toward pandemic-related government sanctions, as well as the resultant effects the restrictions had on community receipt of healthcare.

Background: Glial cells exhibit distinct transcriptional responses to β-amyloid pathology in Alzheimer's disease (AD). While sophisticated single-cell based methods have revealed heterogeneous glial subpopulations in the human AD brain, the histological localization of these multicellular responses to AD pathology has not been fully characterized due to the loss of spatial information. Here, we combined spatial transcriptomics (ST) with immunohistochemistry to explore the molecular mechanisms in the neuritic plaque niche.

In many western countries informal care is conceived as the answer to the increasing care demand. Little is known how formal and informal caregivers collaborate in the context of an diverse ageing population. The aim of this study was to gain insight in how professionals' perspectives regarding the collaboration with informal carers with a migration background are framed and shaped by intersecting aspects of diversity.
