Pheochromocytoma and heart rate variability: a systematic review and meta-analysis

open access: yesInternational Journal of Cardiology. Cardiovascular Risk and Prevention
Introduction: Pheochromocytoma is a catecholamine-producing tumor, that may alter cardiovascular activity. Conveniently, sympathovagal activity can be measured non-intrusively and pain-free through heart rate variability (HRV).

Inflammation, Immunity, and Cardiovascular Diseases

open access: yesMed Research, EarlyView.
Cardiovascular stress signals (e.g., hemodynamic shear, oxidized lipids, and ischemia) act on endothelial and immune cells to activate and amplify inflammation through NF‐κB, the NLRP3 inflammasome, and JAK/STAT signaling, inducing proinflammatory cytokines/chemokines (IL‐6, IL‐1β, TNF‐α, and CCL2) and self‐amplifying circuits; clinically, inflammatory

Ocular muscle metastasis as the initial presentation of a malignant pheochromocytoma: A unique case

open access: yesClinical Case Reports, 2020
In this paper, we discuss a unique manifestation of malignant pheochromocytoma, which presented with ocular pain. The histopathological study pointed to a possible pheochromocytoma origin.

Further Characterization of Dopamine Release by Permeabilized PC 12 Cells [PDF]

open access: yes, 1987
Rat pheochromocytoma cells (PC 12) permeabilized with staphylococcal α-toxin release [3H]dopamine after addition of micromolar Ca2+. This does not require additional Mg2+-ATP (in contrast to bovine adrenal medullary chromaffin cells).

Multi‐Targeting Ligands as Prospective Therapeutics for Alzheimer's Disease, a Prevalent Neurodegenerative Disorder: Mechanistic Insights, Emerging Targets and Drug Discovery Campaigns

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a debilitating neurodegenerative condition characterized by progressive cognitive impairment, memory deterioration, and neuronal dysfunction. Its complex pathophysiology involves multiple interlinked processes, including amyloid‐β (Aβ) aggregation, tau hyperphosphorylation, oxidative stress, neuroinflammation ...

Effects of Tributyltin Chloride on Human Neuronal Differentiation and Mice Brain Development

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT According to the developmental origins of health and disease hypothesis, perinatal exposure to an environmental toxicant during the development of the nervous system could cause a permanent cellular modification that may promote the appearance of neurodegenerative diseases at an older age.
