The incidence of cerebral apoplexy has been on the rise in recent years, and research on the treatment and care of this disease has also received much attention. Therefore, a clinical study of neurological care for cerebral apoplexy rehabilitation care was conducted. Firstly, the Diffie-Hellman key exchange algorithm is introduced, and then the Diffie-Hellman prediction model is established. The patient is taken as an example to carry out simulation test, and the prediction model is compared with the real data. The data of the network model training set, the verification set and the test set are obtained. Patients were divided into observation group and control group by random number table method. The evaluation indicators included the treatment efficiency and the quality of life of the two groups. The results showed that the effective rate of the observation group was higher than that of the control group, and the difference between the two groups was statistically significant (P < 0.05). The experiment proves that the clinical effect of neurological nursing on cerebral apoplexy rehabilitation nursing is positive, which can improve the limb movement and self-living ability of patients, improve the quality of life of patients and improve patient satisfaction. Clinical study of neurology nursing on cerebral apoplexy rehabilitation nursing is discussed in this paper, and the rehabilitation nursing method and formal standardized nursing process of this disease are standardized.

Workplace accommodations can reduce barriers to employment for people who use augmentative and alternative communication (AAC), however, the lack of accommodations continues to challenge participation in employment. This systematic review identified and analyzed barriers and facilitators to implementing workplace accommodations for adults (19 years and over) who use AAC. A systematic search of nine databases was conducted to identify relevant studies using the search terms "AAC" and "workplace accommodations" and variations of each term. Results were imported into Covidence. Seventeen studies met the inclusion criteria. Results were presented using the International Classification of Functioning, Disability, and Health (ICF) framework. The Oxford levels of evidence and Confidence in Evidence from Review of Qualitative Research (GRADE-CERQual) were used to assess the quality of the studies and confidence in findings, respectively. Environmental barriers related mainly to attitudes and technology, and personal barriers related to job qualifications, education, and work-related skills. A combination of facilitators such as personal strengths, access to technology, and supportive relationships contributed to successful implementation of accommodations. The findings of this review suggest that implementing workplace accommodations for adults who use AAC strategies is complex and further research is needed to advance practices and policies that support the implementation of workplace accommodations.

Amyloid precursor protein (APP) metabolism is central to Alzheimer's disease (AD) pathogenesis, but the key etiological driver remains elusive. Recent failures of clinical trials targeting amyloid-β (Aβ) peptides, the proteolytic fragments of amyloid precursor protein (APP) that are the main component of amyloid plaques, suggest that the proteostasis-disrupting, key pathogenic species remain to be identified. Previous studies suggest that APP C-terminal fragment (APP.C99) can cause disease in an Aβ-independent manner. The mechanism of APP.C99 pathogenesis is incompletely understood. We used Drosophila models expressing APP.C99 with the native ER-targeting signal of human APP, expressing full-length human APP only, or co-expressing full-length human APP and β-secretase (BACE), to investigate mechanisms of APP.C99 pathogenesis. Key findings are validated in mammalian cell culture models, mouse 5xFAD model, and postmortem AD patient brain materials. We find that ribosomes stall at the ER membrane during co-translational translocation of APP.C99, activating ribosome-associated quality control (RQC) to resolve ribosome collision and stalled translation. Stalled APP.C99 species with C-terminal extensions (CAT-tails) resulting from inadequate RQC are prone to aggregation, causing endolysosomal and autophagy defects and seeding the aggregation of amyloid β peptides, the main component of amyloid plaques. Genetically removing stalled and CAT-tailed APP.C99 rescued proteostasis failure, endolysosomal/autophagy dysfunction, neuromuscular degeneration, and cognitive deficits in AD models. Our finding of RQC factor deposition at the core of amyloid plaques from AD brains further supports the central role of defective RQC of ribosome collision and stalled translation in AD pathogenesis. These findings demonstrate that amyloid plaque formation is the consequence and manifestation of a deeper level proteostasis failure caused by inadequate RQC of translational stalling and the resultant aberrantly modified APP.C99 species, previously unrecognized etiological drivers of AD and newly discovered therapeutic targets.

To address the lack of reliable measurement methods for identifying wear mechanisms and predicting the state of mechanical seal tribo-parts, this study proposes a method for characterizing tribological behavior based on measuring face vibration acceleration. It aims to uncover the source mechanism of mechanical seal face vibration acceleration influenced by tribology and dynamic behavior. This research delves into the dynamic behavior characteristics and vibration acceleration of the mechanical seal stationary ring. We explored the variation pattern of face vibration acceleration root mean square (RMS) with rotation speed, sealing medium pressure, and face surface roughness. The results indicate that under constant medium pressure, an increase in rotation speed leads to a decrease in acceleration RMS and an increase in face temperature. Similarly, under constant rotation speed, an increase in medium pressure results in nonlinear changes in acceleration RMS, forming an "M" shape, along with an increase in face temperature. Furthermore, under conditions of constant medium pressure and rotation speed, an increase in the surface roughness of the rotating ring face corresponds to an increase in acceleration RMS and face temperature. Upon starting the mechanical seal, both acceleration RMS and temperature initially increase before decreasing, a trend consistent with the Stribeck curve. [ABSTRACT FROM AUTHOR]
