N N Vakhnina, V V Zakharov
Disturbances of gait and postural stability are characteristic of the chronic progressive vascular lesion of the brain observed in moderate to severe stages of cerebrovascular disease. Disconnections between the prefrontal cortex, basal ganglia and cerebellum due to the damage of the white matter (vascular leukoencephalopathy) underlie disturbances of gait and postural stability (shorter stride length, wider gait). There are difficulties in starting with possible stoppings during the walking, waiting in front of small barriers as well as difficulties in concentration (e...

Scutellarin (1) has been widely used to treat acute cerebral infarction in clinic, but poor aqueous solubility decreases its bioavailability. Interestingly, scutellarin (1) could be metabolized into scutellarein (2) in vivo. In this study, a sulfonic group was introduced at position C-8 of scutellarein (2) to enhance the aqueous solubility of the obtained derivative (3). DPPH (1,1-diphenyl-2-picrylhydrazyl)-radical scavenging ability and antithrombic activity were also conducted to determine its bioactivity...

BACKGROUND: Patients with chronic kidney disease (CKD) have worse adverse cardiovascular outcomes after coronary artery bypass grafting (CABG). However, the adverse cardiovascular outcomes between off-pump coronary artery bypass grafting (OPCAB) versus on-pump coronary artery bypass grafting (ONCAB) in these patients have been a subject of debate. METHODS: We undertook a comprehensive literature search of PubMed, Embase, and the Cochrane Library database to identify all relevant studies comparing techniques between OPCAB and ONCAB in CKD patients...

Heart rate (HR) is associated with cardiovascular outcomes in all the stages of the cardiovascular continuum as well as in patients with pulmonary, cerebrovascular, and renal disease, sepsis, cancer, and erectile dysfunction. In patients with cardiovascular disease, but also in the general population, increased HR represents an important indicator of mortality with each acceleration of HR over 70 b.p.m. increasing the risk. In patients in sinus rhythm with chronic heart failure with reduced ejection fraction (HFrEF), a HR >70 b...

Cerebrovascular dysfunction is re-emerging as a major component of aging, and may contribute to the risk of developing Alzheimer's disease (AD). Two important risk factors for cerebrovascular dysfunction are APOE and female sex, which are primarily researched in the context of high amyloid-β (Aβ) levels as found in AD. However, APOE4 and sex modulate Aβ-independent pathways that may induce cerebrovascular dysfunction as a downstream consequence. Therefore, testing the activity of factors that target cerebrovascular dysfunction in Aβ-independent models that incorporate APOE4 and female sex is crucial...

In Lao People's Democratic Republic (Lao PDR), the cause of death is not registered in death reports. As a result, the government cannot produce official reports that show mortality according to cause of death. This study aimed to report the underlying cause of death in a tertiary general hospital (Mittaphab Hospital) in Vientiane capital. Mittaphab hospital is a governmental teaching hospital with 300 beds for inpatient services specialized in orthopedics, neurology, and hemodialysis. Since a children hospital exists beside Mittaphab Hospital, severe pediatric cases are referred to the child hospital...

BACKGROUND: Neurofibromatosis type 1 (NF1) is a rare disease with an incidence of one in every 3000 births. Numerous studies have focused on the main function of NF1 as a tumor suppressor, while few have examined the cerebrovascular abnormalities observed in patients with NF1. It is worth noting that intracranial aneurysms are uncommon in this condition. CASE DESCRIPTION: We report a case of NF1 with a dissection of the distal segment of the superior cerebellar artery...

Aneurysmal subarachnoid hemorrhage (aSAH) is a life-threatening hemorrhagic cerebrovascular disease. The concept of early brain injury (EBI), induced by sharply increased intracranial pressure (ICP) and low cerebral perfusion pressure (CPP) with cerebral global ischemia following aneurysm rupture, has been increasingly accepted. However, EBI has not been well studied partly due to lack of an ideal animal model. The purpose of this study was to establish a new aSAH model which can mimic the pathophysiological damage of EBI...

Dermcidin (DCD) was found in isolated human skin sweat glands with antimicrobial effect, and was defined as a kind of new small molecule antimicrobial peptide. It was a part of human sweat glands in the skin as the immune system's innate defense. With the studies of DCD, its extensive biological functions are gradually discovered. Since 2010, a number of studies have shown that DCD may be a new risk factor for atherosclerosis. And the role of DCD in ischemic heart disease has drawn increasing attention in particular its relationship with insulin secretion and glycemic control, nitric oxide (NO) synthesis and hypertension, platelet aggregation and acute myocardial infarction (AMI)...

Several large-scale genome-wide association studies have identified single-nucleotide polymorphisms in the genomic region of A Disintegrin And Metalloproteinase with ThromboSpondin type 1 repeats (ADAMTS)-7 and associations to coronary artery disease. Experimental studies have provided evidence for a functional role of ADAMTS-7 in both injury-induced vascular neointima formation and development of atherosclerotic lesions. However, whether ADAMTS-7 is associated with a specific plaque phenotype in humans has not been investigated...

von Willebrand factor (vWF) is a multimeric glycoprotein present in blood plasma. It is synthesized in megakaryocytes and endothelial cells, secreted into circulation in the form of high-molecular-weight multimers (HMWMs), and cleaved into shorter, less active multimers by ADAMTS13. It is essential for platelet adhesion and aggregation. Previous studies have investigated the relationship between vWF levels and thromboembolic events with little regard to vWF multimeric structure. Patients with atrial fibrillation (AF) exhibit higher plasma vWF and lower ADAMTS13 levels...
