Ongoing challenges in the provision of care, driven by growing care complexity and nursing shortages, prompt us to reconsider the basis for efficient division of nursing labour. In organising nursing work, traditionally the focus has been on identifying nursing tasks that can be delegated to other less expensive and less highly educated staff, in order to make best use of scarce resources. We argue that nursing care activities are connected and intertwined.

Microplastic ingestion by an aquatic ciliate: Functional response, modulation, and reduced population growth.

Sci Total Environ

January 2025

Department of Life Sciences, Whitelands College, Roehampton University, London SW15 4JD, United Kingdom; Networks Unit, IMT School for Advanced Studies Lucca, Italy.

Microplastic particles are ubiquitous in aquatic environments and are considered a major threat to the large range of heterotrophic organisms that involuntarily consume them. However, there is current uncertainty around the mechanisms underpinning microplastic uptake by aquatic consumers and the consequences for both the fate of the microplastics and the growth potential of consumer populations. We performed a feeding experiment, exposing a model freshwater ciliate, Tetrahymena pyriformis, to six different microplastic concentrations and measured microplastic uptake and population growth over the course of several generations.

Assessment of residential renewable energy investment under dynamic market environment: Aspect from household benefits.

J Environ Manage

January 2025

Graduate School of Media and Governance, Keio University, 5322 Endo, Fujisawa City, Kanagawa Prefecture, 252-0882, Japan. Electronic address:

The adoption of residential renewable energy is pivotal for achieving the 'Net Zero' goal, yet financial assessments of household investments in this area remain complex due to dynamic market conditions. This study introduces a novel closed-form financial valuation framework for residential solar photovoltaic (PV) systems, explicitly addressing the uncertainties of electricity market price fluctuations (market risk) and energy policy changes (policy risk) using Geometric Brownian Motion (GBM). A case study in France demonstrates the framework's application, revealing that the discount rate is the most influential factor in solar PV valuation, followed by system lifespan and policy-driven Feed-in Tariff (FiT) rates.

Introduction: Despite research supporting menopause hormonal therapy for menopausal women, its use continues to decline in most European countries and the United States. Experts highlighted the need for global assessment tools to assist clinicians in evaluating treatment for symptomatic menopausal women, which led to the development of the Menopause Treatment Tool, with separate versions for women and healthcare professionals. Both versions of the tool focus on menopausal symptoms, risk levels and suggested actions; the women's tool is administered prior to the consultation, while the clinician tool is administered by the clinician during the clinical consultation.

Evidence for the independent evolution of a rectal complex within the beetle superfamily Scarabaeoidea.

Arthropod Struct Dev

January 2025

Department of Agronomy, Food, Natural Resources, Animals and Environment (DAFNAE) - University of Padua, Viale dell'Università 16, 35020, Legnaro, Padua, Italy.

Rectal or cryptonephridial complexes have evolved repeatedly in arthropods, including in beetles where they occur in ∼190,000 species of Cucujiformia + Bostrichoidea, and Lepidoptera where they occur in ∼160,000 species. Sections of the Malpighian/renal tubules coat the outer surface of the rectum, acting as powerful recycling systems of the gut contents, recovering water and specific solutes. There are hints that a rectal complex evolved independently within another beetle group, Scarabaeoidea.

CD-44 targeted nanoparticles for combination therapy in an in vitro model of triple-negative breast cancer: Targeting the tumour inside out.

Colloids Surf B Biointerfaces

January 2025

Institute of Cancer Therapeutics, University of Bradford, Bradford, Richmond Rd, Bradford BD7 1DP, United Kingdom. Electronic address:

Triple-negative breast cancer (TNBC) is an aggressive form of breast cancer defined by the lack of three key receptors: estrogen, progesterone, and HER2. This lack of receptors makes TNBC difficult to treat with hormone therapy or drugs, and so it is characterised by a poor prognosis compared to other kinds of breast cancer. This study explores photoactive Poly(lactic-co-glycolic acid) (PLGA) nanoparticles as a potential therapeutic strategy for TNBC.

Engine deposits can reduce performance and increase emissions, particularly for modern direct-injection fuel delivery systems. Surfactants known as deposit control additives (DCAs) adsorb and self-assemble on the surface of deposit precursors to keep them suspended in the fuel. Here, we show how molecular simulations can be used to virtually screen the ability of surfactants to bind to polyaromatic hydrocarbons, comprising a major class of carbonaceous deposits.
