A density-based MS disease diagnosis model using the capuchin search algorithm and an ensemble of deep neural networks.

Multiple sclerosis (MS) is a severe brain disease that permanently destroys brain cells, impacting vision, balance, muscle control, and daily activity. This research employs a weighted combination of deep neural networks and optimization techniques for MS disease diagnosis. This method uses slices of magnetic resonance imaging (MRI) images as input.

Anticholinergic drugs and the risk of dementia: A systematic review and meta-analysis.

Dementia is one of the greatest global challenges for public health; however, the relationship between anticholinergic drugs and dementia remains unclear. The aim of the present study was to perform a systematic review and meta-analysis of the predictive roles of anticholinergic drugs in dementia risk. After pooling fourteen longitudinal and case-control studies with a total of 1,564,181 subjects, anticholinergic drug use was associated with an increased risk of all-cause dementia and Alzheimer's disease.

Nrf2 protects against diabetic dysfunction of endothelial progenitor cells via regulating cell senescence.

Diabetes is associated with an increased risk of cardiovascular disease. A decrease in the number and functionality of endothelial progenitor cells (EPCs) leads to reduced endothelial repair and the development of cardiovascular disease. The aim of the present study was to explore the effect and underlying mechanisms of nuclear factor erythroid 2‑related factor 2 (Nrf2) on EPC dysfunction caused by diabetic mellitus.

[Microsatellite DNA polymorphism of adrenomedullin gene and atherosclerotic cerebral infarction].

Objective: To detect the correlation between the microsatellite DNA polymorphism of adrenomedullin(ADM) gene (repeated sequences of CA) and the atherosclerotic cerebral infarction (ACI).

Methods: With PCR, ADM genotype was monitored from 189 normotensive subjects and 283 cerebral infarction patients. By using radioimmunoassay, their plasma ADM concentration was measured, so as the biochemical index.

Effect of adrenomedullin on neuron apoptosis, infarction volume and expression of Egr-1 mRNA after focal ischemia-reperfusion in rats.

Objective To observe the influence of adrenomedullin (ADM) on neuron apoptosis, infarction volume of brain, and the expression of early growth response 1 (Egr-1) mRNA in ischemia-reperfusion rats. Methods The arteria cerebri media was tied for 2 h to construct the ischemia model. Infarction volume was detected by triphenltetrazolium chloride (TTC) staining, neuronal apoptosis and necrosis was detected with terminal deoxynucleotidyl transferase nick labeling (TUNEL) method, and the Egr-1 mRNA expression was examined by in situ hybridization (ISH).

[Effect of adrenomedullin on neuron apoptosis and early growth response gene-1 after focal ischemia/ reperfusion in rats].

Objective: To explore the influence of adrenomedullin (ADM) on apoptosis of neuron, volume of infarction and the expression of early growth response gene-1 (Egr-1) mRNA in the rat with focal ischemia/reperfusion (I/R) injury.

Methods: Fifty-four SD rats were randomly divided into sham operation group, ADM femoral vein group, internal carotid artery group and lateral cerebral ventricle group. The model was reproduced by ligating the middle cerebral artery (MCA) with a ligature for 2 hours followed by injection of ADM through femoral artery, internal carotid artery and lateral cerebral ventricle before reperfusion for 22 hours.
