Haemodynamic effects of nicardipine were studied in 12 patients with coronary artery disease. After 10 mg i.v. at rest heart rate increased (P less than 0.001); mean arterial pressure decreased (P less than 0.001); systemic vascular resistance decreased (P less than 0.001); cardiac output increased (P less than 0.001) and left ventricular end-diastolic pressure did not change. Exercise at control levels showed an increase (P less than 0.001) of heart rate and cardiac index and decreases of mean arterial pressure, systemic vascular resistance and left ventricular end-diastolic pressure (P less than 0.001). The ejection fraction response to exercise did not change. During exercise nicardipine prevented angina pectoris in 8/12 patients. Nicardipine is a potent vasodilator, which produced a marked reduction of systemic vascular resistance and left ventricular end-diastolic pressure during exercise. Angina pectoris was prevented on exercise in the majority of patients after intravenous administration.

Background: Tyrosine kinase inhibitors (TKIs) improve prognosis in chronic myeloid leukemia (CML). Nilotinib and ponatinib, second- and third-generation TKIs, respectively, have been reported to cause adverse vascular occlusive events such as myocardial infarction and peripheral arterial disease. However, little is known about the risk of cerebral infarction associated with severe cerebrovascular stenosis, which is a late complication of TKIs.

Cytokine storm is a life-threatening systemic hyper-inflammatory state caused by different etiologies, in which the bulk production of pro-inflammatory cytokines from activated macrophages has a central role. Integrated stress response (ISR) comprises several protective signaling pathways, leading to phosphorylation of eukaryotic initiation factor 2α (eIF2α) and repression of protein translation. Emerging evidence suggests that ISR induction may elicit anti-inflammatory effects.

Fluid shear stress (FSS) from blood flow sensed by vascular endothelial cells (ECs) determines vessel behavior, but regulatory mechanisms are only partially understood. We used cell state transition assessment and regulation (cSTAR), a powerful computational method, to elucidate EC transcriptomic states under low shear stress (LSS), physiological shear stress (PSS), high shear stress (HSS), and oscillatory shear stress (OSS) that induce vessel inward remodeling, stabilization, outward remodeling, or disease susceptibility, respectively. Combined with a publicly available database on EC transcriptomic responses to drug treatments, this approach inferred a regulatory network controlling EC states and made several notable predictions.

Background: Individuals with Down syndrome (DS) have an increased genetic risk of developing Alzheimer's disease (AD), with most adults developing AD neuropathology in their 40s. Despite having a low frequency of systemic vascular risk factors such as hypertension and atherosclerosis, adults with DS display cerebrovascular pathology, including microbleeds, microinfarcts, and cerebral amyloid angiopathy. This suggests that blood-brain barrier (BBB) integrity may be compromised allowing the extravasation of blood proteins in the brain parenchyma.

Assessing the composition of immune pathways in neurodegenerative diseases can contribute to precision medicine. Using publicly available transcriptomic data, we sought to elucidate transcriptional networks pertinent to inflammatory pathways across brain regions and peripheral blood in AD/mild cognitive impairment (MCI) and peripheral blood in Parkinson's disease (PD).
