The New Nitric Oxide Donor, FOR 911B, Induces Relaxation in Isolated Rat Aorta Involving the NO/sGC/cGMP Pathway and K+ Channels

open access: yesReceptors
Background: Nitric oxide (NO) is a gaseous molecule considered to be a protagonist in the dilation of blood vessels, and its property and/or bioavailability are reduced in pathophysiological conditions such as cardiovascular diseases.

Zofenopril: Blood pressure control and cardio-protection

open access: yesCardiology Journal, 2022
Current hypertension guidelines suggest various strategies to reduce blood pressure levels, thereby reducing cardiovascular events: combinations of drugs with different mechanisms of action, such as an angiotensin converting enzyme inhibitors (ACEIs) and

NIR‐II‐Trackable LYTACs Phyto‐Nanotheranostics for Source‐Microenvironment Dual‐Track ROS Regulation in Acute Gouty Arthritis

open access: yesAdvanced Science, EarlyView.
The TPR‐LYTACs nanomaterial offers a dual‐pathway strategy for precise gouty arthritis treatment by targeting and degrading the ROS‐producing enzyme NOX2 inside macrophages while its antioxidant core clears accumulated ROS outside. This “source inhibition and microenvironment scavenging” approach, guided by NIR‐II imaging, effectively controls local ...

Estrogen Receptors and Estrogen-Induced Uterine Vasodilation in Pregnancy [PDF]

open access: yes, 2020
Normal pregnancy is associated with dramatic increases in uterine blood flow to facilitate the bidirectional maternal-fetal exchanges of respiratory gases and to provide sole nutrient support for fetal growth and survival.

Enhancing Blood Circulation With Epsilon‐Near‐Zero (ENZ) Materials via the Far‐Infrared Window of Human Skin

open access: yesAdvanced Science, EarlyView.
Epsilon‐near‐zero (ENZ) silicon carbide enables a selective far‐infrared emitter spectrally aligned with the human skin window around 10 µm for wavelength‐matched thermal therapy. In 25 within‐subject trials (50 hands) monitored by laser speckle contrast imaging, SiC increases blood perfusion by 30.2% versus a broadband graphite emitter while ...

Vasodilation increases pulse pressure variation, mimicking hypovolemic status in rabbits

open access: yesClinics, 2010
OBJECTIVE: To test the hypothesis that pulse pressure respiratory variation (PPV) amplification, observed in hypovolemia, can also be observed during sodium nitroprusside (SNP)-induced vasodilation.

Hydrogen Sulfide-Induced Vasodilation: The Involvement of Vascular Potassium Channels

open access: yesFrontiers in Pharmacology, 2022
Hydrogen sulfide (H2S) has been highlighted as an important gasotransmitter in mammals. A growing number of studies have indicated that H2S plays a key role in the pathophysiology of vascular diseases and physiological vascular homeostasis. Alteration in

Neurons intrinsic to arterioles initiate postcontraction vasodilation

open access: yes, 1976
Ganglion cells exist in muscle arterioles. To determine the role of these intrinsic neurons in postcontraction vasodilation, isolated dog gracilis muscles were studied.
