Nurses' Experience of Good Nursing Care for Terminally Ill and End-of-life Patients: The Client-Nurse, Practice, and Environment Domains.

Purpose: This study explored nurses' experience of "good nursing care" in the context of caring for terminally ill and end-of-life patients, providing a foundation for improving patient care.

Methods: We employed a qualitative research approach, integrating both inductive and deductive analysis methods. Data collection occurred from May 1 to August 1, 2023, involving nine nurses from intensive care units, hospice and palliative care wards, and nursing homes.

Neuroimaging findings of adolescent depression: A review by the Research Domain Criteria (RDoC) framework.

This review examines neuroimaging studies on adolescent depression (AD) within the Research Domain Criteria (RDoC) framework, focusing on fMRI, DTI, and EEG findings. The research highlights disrupted connectivity in several neural networks-such as the affective, reward processing, cognitive control, and default mode networks-that underpin emotional and cognitive dysfunctions in AD. Notably, hypoconnectivity in the affective and cognitive control networks correlates with deficits in emotional processing and executive functioning, while hyperactivity in the default mode network relates to excessive self-referential thoughts.

Fetal fraction amplification within prenatal cfDNA screening enables detection of genome-wide copy-number variants at enhanced resolution.

Purpose: Clinically significant copy-number variants (CNVs) occur in 1% to 2% of pregnancies and are difficult to detect via prenatal cell-free DNA (cfDNA) screening because of the low fraction of fetal-derived cfDNA in maternal plasma. Here, we use fetal fraction amplification (FFA) and improved computational algorithms to enhance the resolution and sensitivity of CNV detection.

Methods: We implemented and characterized the performance of a hidden Markov model that identifies fetal CNVs.

Electron Release via Internal Polarization Fields for Optimal S-H Bonding States.

Transition metal dichalcogenides (TMDs) have received considerable attention as promising electrocatalysts for the hydrogen evolution reaction (HER), yet their potential is often constrained by the inertness of the basal planes arising from their poor hydrogen adsorption ability. Here, the relationship between the electronic structure of the WS basal plane and HER activity is systemically analyzed to establish a clear insight. The valance state of the sulfur atoms on the basal plane has been tuned to enhance hydrogen adsorption through sequential engineering processes, including direct phase transition and heterostructure that induces work function-difference-induced unidirectional electron transfer.

Brain Nucleic Acid Delivery and Genome Editing via Focused Ultrasound-Mediated Blood-Brain Barrier Opening and Long-Circulating Nanoparticles.

We introduce a two-pronged strategy comprising focused ultrasound (FUS)-mediated blood-brain barrier (BBB) opening and long-circulating biodegradable nanoparticles (NPs) for systemic delivery of nucleic acids to the brain. Biodegradable poly(β-amino ester) polymer-based NPs were engineered to stably package various types of nucleic acid payloads and enable prolonged systemic circulation while retaining excellent serum stability. FUS was applied to a predetermined coordinate within the brain to transiently open the BBB, thereby allowing the systemically administered long-circulating NPs to traverse the BBB and accumulate in the FUS-treated brain region, where plasmid DNA or mRNA payloads produced reporter proteins in astrocytes and neurons.
