Targeting the ARRDC3–DRP1 Axis via hUMSC‐Derived Exosomal CRYAB for Neuroprotection in Cerebral Ischemia/Reperfusion Injury

Advanced Healthcare Materials, EarlyView.
Intranasally administered hUMSC‐derived exosomes modulate the CRYAB–ARRDC3–Drp1 axis, alleviating mitochondrial dysfunction and ferroptosis, enhancing neuronal survival, reducing oxidative stress, and promoting functional recovery in ischemia‐reperfusion injury, offering a promising therapeutic strategy for ischemic stroke.

Human Brain Vasculature‐on‐a‐Chip Model Constructed With Microvessels Isolated From Cryopreserved Postmortem Human Brain Tissue

Advanced Healthcare Materials, EarlyView.
This manuscript describes the cultivation of viable microvessels from cryopreserved human brain tissue. When embedded in hydrogels and cultured in microfluidic devices, these microvessels exhibit complex architectures reminiscent of arterioles and capillaries, can be perfused, and display intact barrier function. Collectively, these results demonstrate

Ação da adenosina na circulação pulmonar de pacientes com hipertensão pulmonar primária Effect of adenosine on pulmonary circulation in patients with primary pulmonary hypertension

Jornal Brasileiro de Pneumologia, 2005
INTRODUÇÃO: A adenosina é um nucleosídeo com potente ação vasodilatadora. Apesar de seus efeitos sobre o território arterial pulmonar ser conhecido, seu efeito sobre o território capilar/venoso ainda não foi descrito.
