Preventive effect of Tyr-Pro, a blood-brain barrier transportable dipeptide, on memory impairment in SAMP8 mice.

In a series of studies on blood-brain barrier transportable peptides, a soybean dipeptide, Tyr-Pro, penetrated the mouse brain parenchyma after oral intake and improved short and long memory impairment in acute Alzheimer's model mice. Here, we aimed to clarify the anti-dementia effects of this peptide administered to SAMP8 mice prior to dementia onset. At the end of the 25-week protocol in 16-week-old SAMP8 mice, Tyr-Pro (10 mg/kg/day) significantly improved the reduced spatial learning ability compared with that in the control and amino acid (Tyr + Pro) groups as indicated by the results of Morris water maze tests conducted for five consecutive days.

The chain mediating role of rumination and psychological resilience in symptom burden and kinesiophobia in patients with chronic heart failure.

Objective: To explore the chain-mediating role and impact of rumination and psychological resilience on symptom burden and kinesiophobia in patients with chronic heart failure.

Methods: We selected a total of 318 patients with chronic heart failure from a hospital in Wuxi between November 2023 and May 2024 using a convenience sampling method. Various scales and questionnaires assessed general information, symptom burden, resilience, rumination thinking, and kinesiophobia.

Prevalence and related factors of compassion fatigue among registered nurses and nursing students during the internship: a systematic review and meta-analysis.

Background: Compassion fatigue impacts nurses' well-being and work efficiency. Extensive research has explored its prevalence, but evidence regarding related factors is broadly categorized and lacks descriptive data. There's also a lack of systematic reviews on compassion fatigue among nursing students during internships.

North Atlantic Heat Transport Convergence Derived from a Regional Energy Budget Using Different Ocean Heat Content Estimates.

This study uses an oceanic energy budget to estimate the ocean heat transport convergence in the North Atlantic during 2005-2018. The horizontal convergence of the ocean heat transport is estimated using ocean heat content tendency primarily derived from satellite altimetry combined with space gravimetry. The net surface energy fluxes are inferred from mass-corrected divergence of atmospheric energy transport and tendency of the ECMWF ERA5 reanalysis combined with top-of-the-atmosphere radiative fluxes from the clouds and the Earth's radiant energy system project.

Impaired visual attention and numerical processing in children with anisometropic amblyopia and after visual acuity recovery.

Amblyopia affects more than visual acuity. To compare the performances of visual selective attention and numerical processing in children with anisometropic amblyopia and children with normal vision, and investigate whether performance would be improved after visual acuity recovery, we performed 3 visual attention tasks (identifying number location task, numerical comparison task, and specific number comparison task) in children with anisometropic amblyopia, children who had recovered from anisometropic amblyopia, and children with normal vision in 6-8 and 9-11 years groups. The numerical processing ability, visual selective attention, and numerical distance effect were assessed by their reaction time of different tasks.
