Cutaneous blood flow and microcirculation underpin critical physiological processes including thermoregulation, nutrient delivery and immune defence. The skin’s vascular network, comprising ...

Light speckle fluctuations, a noninvasive proxy for cerebral blood flow index (CBFi), are quantified by diffuse correlation spectroscopy. However, this conventional technique provides marginal brain ...

Measuring blood flow in the brain is critical for responding to a range of neurological problems, including stroke, traumatic brain injury (TBI) and vascular dementia. But existing techniques, ...

New noninvasive tools reveal that subtle shifts in brain blood flow and oxygen use may mirror key markers of Alzheimer’s risk ...

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

A wearable ultrasound patch could soon be saving lives, by monitoring the blood flow in hospital patients' brains. The device is only about the size of a postage stamp plus it works continuously, ...

According to the National Heart, Lung, and Blood Institute, nearly 10 million people aged 40 and older have Peripheral Artery Disease (PAD). PAD may cause poor circulation. People who are older than ...

Sugar, often considered a delightful indulgence, plays a significant role in our daily lives. Its presence is ubiquitous, from sweet treats to hidden sugars in processed foods. While it can enhance ...
