Machine learning models identify ferroptosis-related genes as potential diagnostic biomarkers for Alzheimer's disease.

Alzheimer's disease (AD) is a complex, and multifactorial neurodegenerative disease. Previous studies have revealed that oxidative stress, synaptic toxicity, autophagy, and neuroinflammation play crucial roles in the progress of AD, however, its pathogenesis is still unclear. Recent researches have indicated that ferroptosis, an iron-dependent programmed cell death, might be involved in the pathogenesis of AD.

Effects of whole body vibration combined with extracorporeal shock wave therapy on spasticity and balance gait parameters in hemiplegic patients with stroke.

Objectives: Stroke patients may have various sensory-motor disorders, such as spasticity, muscle weakness or sensory damage. Spasticity affects 20% to 40% of stroke patients. Patients with spasticity may have problems such as pain, motor function damage, and the decreased range of motion, which leads to decline of activity and quality of daily life.

Identification of EMT-Related lncRNAs as Potential Prognostic Biomarkers and Therapeutic Targets for Pancreatic Adenocarcinoma.

Epithelial-mesenchymal transition (EMT) can promote carcinoma progression by multiple mechanisms; many studies demonstrated the invasiveness of pancreatic adenocarcinoma (PAAD) associated with the EMT, but how it acts through an lncRNA-dependent manner is unknown. Here, we investigated 146 samples from The Cancer Genome Atlas (TCGA) and 92 samples from the International Cancer Genome Consortium (ICGC). By gene set variation analysis (GSVA) and weighted correlation network analysis (WGCNA), we explored the EMT-related long noncoding RNAs (EMTlnc).

Eight-and-a-Half Syndrome: A Combination of Intracranial Capillary Telangiectasia and Hematencephalon.

Eight-and-a-half syndrome, a combination of one-and-a-half syndrome and ipsilateral facial palsy, was first described by Eggenberger in 1998. Intracranial capillary telangiectasia (ICT) is a rare type of latent cerebral vascular malformation characterized by a number of small, dilated, and thin-walled blood capillaries with normal brain tissues between them. Susceptibility weighted imaging is the recommended diagnostic method to detect ICT.

Relationship between Adiponectin Gene Polymorphisms and Late-Onset Alzheimer's Disease.

In recent years, researchers have found that adiponectin (ANP) plays an important role in the pathogenesis of Alzheimer's disease (AD), and low serum concentrations of ANP are associated with AD. Higher plasma ANP level have a protective effect against the development of cognitive decline, suggesting that ANP may affect AD onset. Meanwhile, accumulating evidence supports the crucial role of ANP in the pathogenesis of AD.
