Using the Analytic Hierarchy Process to Measure Nurses' Decision-Making Regarding Fall Risks and Care Strategies for Fall Prevention.

Visualizing the thought processes of nurses is useful in forming evidence to prevent falls. This study aimed to quantify nursing judgment by comparing the choices made by nurses with different experiences regarding fall prevention. Questionnaires were administered to participants with <9 and ≥10 years of nursing experience to examine their importance ratings regarding fall prevention using an analytic hierarchy process (AHP).

The transcription factor NF-YA is crucial for neural progenitor maintenance during brain development.

In contrast to stage-specific transcription factors, the role of ubiquitous transcription factors in neuronal development remains a matter of scrutiny. Here, we demonstrated that a ubiquitous factor NF-Y is essential for neural progenitor maintenance during brain morphogenesis. Deletion of the NF-YA subunit in neural progenitors by using nestin-cre transgene in mice resulted in significant abnormalities in brain morphology, including a thinner cerebral cortex and loss of striatum during embryogenesis.

Quantum-dot-labeled synuclein seed assay identifies drugs modulating the experimental prion-like transmission.

Synucleinopathies are neurodegenerative disorders including Parkinson disease (PD), dementia with Lewy body (DLB), and multiple system atrophy (MSA) that involve deposits of the protein alpha-synuclein (α-syn) in the brain. The inoculation of α-syn aggregates derived from synucleinopathy or preformed fibrils (PFF) formed in vitro induces misfolding and deposition of endogenous α-syn. This is referred to as prion-like transmission, and the mechanism is still unknown.

The Effect of Lavender on Sleep Quality in Individuals Without Insomnia: A Systematic Review.

We reviewed 20 randomized controlled trials concerning the intervention methods and effects of lavender essential oil on adults' sleep quality. Fourteen showed positive intervention effects. A mixture of subjective and objective indicators was used.

Amyloids facilitate DNA transfection in vivo.

Amyloid fibril deposits are a main source of pathology in neurodegenerative diseases. Normal proteins such as tau, alpha-synuclein, TDP-43 and others could form specific conformational fibrils called amyloid, which deposited in the brains of neurodegenerative diseases. Although the pathological roles of amyloids in cell death have been discussed a lot, their other functions have not been investigated well.

Proteomic analysis of subcellular compartments containing disseminated alpha-synuclein seeds.

The pathological form of a-synuclein (a-syn) is transmitted through neural circuits in the brains of Parkinson disease (PD) patients and amplifies misfolded a-syn, further forming intracellular deposits. However, the details of a-syn pre-formed fibrils (PFFs) transmission in vivo have not been fully elucidated. By inoculating Quantum dots (QD)-labeled a-syn PFFs (QD-a-syn PFFs) into the unilateral striatum, we detected QD-a-syn PFFs in brain homogenates obtained from the ipsilateral and contralateral sides of the inoculated site and further obtained QD-a-syn PFFs enriched-particles with fluorescence-activated organelle sorting.

Preserved proteinase K-resistant core after amplification of alpha-synuclein aggregates: Implication to disease-related structural study.

Many pathological proteins related to neurodegenerative diseases are misfolded, aggregating to form amyloid fibrils during pathogenesis. One of the pathological proteins, alpha-synuclein (α-syn), accumulates in the brains of Parkinson disease (PD), dementia with Lewy bodies (DLB) and multiple system atrophy (MSA), which are designated as synucleinopathies. Recently, structural properties of abnormal accumulated proteins are suggested to determine the disease phenotype.

Role of lysosomal channel protein TPC2 in osteoclast differentiation and bone remodeling under normal and low-magnesium conditions.

The bone is the main storage site for Ca and Mg ions in the mammalian body. Although investigations into Ca signaling have progressed rapidly and led to better understanding of bone biology, the Mg signaling pathway and associated molecules remain to be elucidated. Here, we investigated the role of a potential Mg signaling-related lysosomal molecule, two-pore channel subtype 2 (TPC2), in osteoclast differentiation and bone remodeling.

Membrane depolarization regulates intracellular RANKL transport in non-excitable osteoblasts.

Parathyroid hormone (PTH) and 1α,25-dihydroxyvitamin D3 (VD3) are important factors in Ca(2+) homeostasis, and promote osteoclastogenesis by modulating receptor activator of nuclear factor kappa-B ligand (RANKL) mRNA expression. However, their contribution to RANKL intracellular transport (RANKLiT), including the trigger for RANKL lysosomal vesicle (RANKL-lv) fusion to the cell membrane, is unclear. In neurons, depolarization of membrane potential increases the intracellular Ca(2+) level ([Ca(2+)]i) and promotes neurotransmitter release via fusion of the synaptic vesicles to the cell membrane.

Zinc-Induced Effects on Osteoclastogenesis Involves Activation of Hyperpolarization-Activated Cyclic Nucleotide Modulated Channels via Changes in Membrane Potential.

Zinc is a trace element in the mammalian body, and increasing evidence shows its critical role in bone development and osteoclastogenesis. The relationships between zinc and voltage-gated ion channels have been reported; however, the effects of zinc on membrane potential and the related ion channels remain unknown. In this study, we found that zinc-induced hyperpolarization in RAW264.
