During hypoxia, tissues are subjected to an inadequate oxygen supply, disrupting the balance needed to maintain normal function. This deficiency can occur due to reduced oxygen delivery caused by impaired blood flow or a decline in the blood's ability to carry oxygen. In tumors, hypoxia and vascularization play crucial roles, shaping their microenvironments and influencing cancer progression, response to treatment and metastatic potential.

Purpose: Concurrent electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) have been used to assist in the presurgical localization of seizure foci in people with epilepsy. Our study aimed to examine the clinical feasibility of an optimized concurrent EEG-fMRI protocol.
Methods: The optimized protocol employed a fast-fMRI sequence (sampling rate = 10 Hz) with a spare arrangement, which allowed a time window of 1.
Virginia Memory Project: Using the Healthy Brain Initiative Roadmap to design a statewide dementia registry.

Introduction: The Virginia Memory Project (VMP) is a statewide epidemiological registry for Alzheimer's disease and related disorders (ADRD) and other neurodegenerative conditions. It aims to support dementia research, policy, and care by leveraging the Centers for Disease Control (CDC) Healthy Brain Initiative (HBI) Roadmap.
Methods: To capture comprehensive data, the VMP integrates self-enrollment and automatic enrollment using Virginia's All-Payer Claims Database (APCD).
Family physicians' perspectives on outcomes, processes, and policies in dementia care.

The rapid rise in numbers of people living with Alzheimer's disease and related disorders (ADRD) poses major challenges to health systems and policy. Although primary care clinicians provide ongoing medical care for 80% of affected individuals, they face persistent barriers to providing high-quality dementia care. We conducted qualitative interviews with family physicians ( = 20) to understand what core outcomes they consider most important and what care processes and systems and policy strategies they propose to achieve them.

Reciprocal neuronal connections exist between the internal organs of the body and the nervous system. These projections to and from the viscera play an essential role in maintaining and finetuning organ responses in order to sustain homeostasis and allostasis. Functional maps of brain regions participating in this bidirectional communication have been previously studied in awake humans and anesthetized rodents.
