In recent decades, our understanding of the molecular changes involved in neurodegenerative diseases has been transformed. Single-cell RNA sequencing and single-nucleus RNA sequencing technologies have been applied to provide cellular and molecular details of the brain at the single-cell level. This has expanded our knowledge of the central nervous system and provided insights into the molecular vulnerability of brain cell types and underlying mechanisms in neurodegenerative diseases. In this review, we highlight the recent advances and findings related to neurodegenerative diseases using these cutting-edge technologies.

Background: Speckles tracking echocardiography imaging enables clinicians to detect subtle systolic dysfunction. The aim of the present study was to elucidate the differences in speckle tracking echocardiographic findings between immunoglobulin light chain amyloid cardiomyopathy (AL-CM) and transthyretin amyloid cardiomyopathy (TTR-CM).
Methods: The patients with a confirmed diagnosis of cardiac amyloidosis through cardiac biopsy from March 2013 to October 2022 were included.

The neuronal ceroid lipofuscinoses (NCLs) are a group of recessively inherited neurodegenerative diseases characterizsed by lysosomal storage of fluorescent materials. CLN3 disease, or juvenile Batten disease, is the most common NCL that is caused by mutations in the Ceroid Lipofuscinosis, Neuronal 3 (CLN3) gene. Sleep disturbances are among the most common symptoms associated with CLN3 disease that deteriorate the patients' life quality, yet this is understudied and has not been delineated in animal models of the disease.

Exercise in heart failure with preserved ejection fraction (HFpEF) remains a hot topic, although current treatment strategies have not been shown to improve the long-term prognosis of HFpEF. Previous studies have mostly focused on the roles of endurance training, the mechanisms underlying long-term voluntary exercise have not been elucidated. The purpose of the present analysis was to evaluate alterations in cardiac function in HFpEF mice (HFpEF-Sed) after 6 weeks of voluntary running (HFpEF-Ex), investigate mechanisms, and compare the effects with fluoxetine (HFpEF-FLX).

Natural aging is associated with mild memory loss and cognitive decline, and age is the greatest risk factor for neurodegenerative diseases, such as Alzheimer's disease. There is substantial evidence that oxidative stress is a major contributor to both natural aging and neurodegenerative disease, and coincidently, levels of redox active metals such as Fe and Cu are known to be elevated later in life. Recently, a pronounced age-related increase in Cu content has been reported to occur in mice and rats around a vital regulatory brain region, the subventricular zone of lateral ventricles.

In this study, network pharmacology analysis revealed that strawberry anthocyanins mainly interfered with lipid metabolism and nerve-related signaling pathways. Pelargonidin-3-glucoside (Pg3G), one of the main anthocyanins in strawberry, was screened as the most effective anthocyanin for attenuating excess lipid accumulation. Moreover, Pg3G decreased lipid levels, relieved oxidative stress, and restored abnormal behavioral activities in under oleic acid (OA) exposure.
