Membrane proteins often need to be inserted into or attached to the cell membrane to perform their functions. Understanding their transmembrane topology and conformational dynamics during insertion is crucial for elucidating their roles. However, it remains challenging to monitor nanoscale changes in the insertion depth of individual proteins in membranes.

Article Synopsis
  • * Scientists used special imaging to see that α-syn can group together in large clusters on these membranes but stay far apart from each other.
  • * Some mutations in α-syn can make these clusters grow too big, which may lead to problems in the brain related to Parkinson's disease.

Unlabelled: WHAT IS KNOWN ON THE SUBJECT?: Physical restraint is widely used in the elderly at home, and cognitive impairment is an important risk factor. Family caregivers of people with dementia are the main decision makers and implementers of physical restraint at home. Most people with dementia in China receive home care, and family caregivers face enormous care and moral pressures influenced by Confucian culture.

Correction for 'Nanomolar LL-37 induces permeability of a biomimetic mitochondrial membrane' by Xin Jiang , , 2022, https://doi.org/10.1039/d2nr05409d.

LL-37, the only human host cathelicidin peptide, is proposed to be able to induce host cell apoptosis through mitochondrial membrane permeabilization (MMP). Detailed pathways of the LL-37-triggered MMP are however still disputed. It is generally believed that cationic peptides permeate a membrane mostly in conditions of micromolar peptide concentrations and negatively charged membranes, which are not usually satisfied in the mitochondrial circumstance.

Background: The phenomenon of physical restraint applied to people with dementia in home care is receiving increasing interest from nursing scholars. Although family caregivers play key roles in caring for people with dementia, little is known regarding the ways in which family caregivers make decisions with respect to physical restraint.

Objectives: The aim of this study was to explore Chinese family caregivers' decision-making regarding physical restraint in home care for persons living with dementia.

Article Synopsis
  • - The study aimed to identify predictors that influence the recovery of complete oral feeding in stroke patients with dysphagia after being placed on feeding tubes, using a systematic review approach informed by the PRISMA guidelines.
  • - Researchers reviewed 15 relevant studies with a total of 1,746 participants, noting significant factors such as demographic info, swallowing function, stroke characteristics, functional status, and clinical measures, but found many studies had a high risk of bias.
  • - A key limitation of the review was its inability to determine predictors for different types of tube feeding, leading to insufficient evidence for drawing definitive conclusions.

Article Synopsis
  • Understanding how membrane proteins work requires tracking their position and shape changes, but this is difficult to do with high sensitivity and resolution.
  • Our lab has developed three new single-molecule fluorescence imaging techniques—SIFA, LipoFRET, and QueenFRET—that help study these proteins in various membrane environments.
  • These methods use energy transfer to accurately measure the position and changes of labeled proteins, achieving sub-nanometer precision and enhancing our ability to investigate biomolecular interactions with membranes.

Background: Many national studies have shown that nurses have a high turnover rate. The key to maintaining the stability of nursing staff is to explore the factors that affect their turnover intention; however, no research has been performed to explore the influencing factors and mechanisms of nurses' turnover intention based on the Theory of Planned Behaviour.

Aim: Based on the Theory of Planned Behaviour, examining the relationships among resilience, job satisfaction, social support and turnover intention of nurses, a structural equation model was constructed to examine the mediating role of job satisfaction and social support between resilience and turnover intention.

Background: Inherited colorectal cancer syndromes increase the risk of contracting colorectal and other cancers. International guidelines recommend the identification of individuals with hereditary colorectal cancer and the supervision of asymptomatic individuals with a family history. However, detection of hereditary colorectal cancer is suboptimal.

The present study aimed to explore the modifiable factors of behavioural and psychological symptoms of dementia (BPSD) among patients residing at home in terms of patient, caregiver and environmental factors. A cross-sectional survey of 193 patients with dementia residing at home and their caregivers who visited the memory clinic of the Department of Neurology in a tertiary (the highest level) hospital in China from November 2018 to May 2019 was performed. Exacerbated BPSD were associated with patient (old age, high education level, increased dementia severity, and the use of psychotropic drugs), caregiver (low positive aspects and high expressed emotion) and environmental (poor home environment) factors.
