Brain metastasis (BrM) poses a significant challenge to the prognosis and quality of life for patients with non-small cell lung cancer (NSCLC). Gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter in the central nervous system (CNS), has been i
Rhythmicity: It is the capacity of a cardiac tissue to generate its own impulses regularly. This property is also known as self-excitation or autorhythmicity. All of the tissues of the heart own this feature. However, in the human heart, there is an exclusive excitatory structure that produces...
Present in varying amounts around all arteries bar the cerebral artery and microcirculation [20]. 3. Physiological roles of the cardiac and vascular adipose depots 3.1. Paracardial adipose tissue Little is known about its precise role with most studies predominantly focussed on either perivascular or...
Reconstruction of stenotic or occluded iliofemoral veins and inferior vena cava using intravascular stents: re-establishing access for future cardiac catheterization and cardiac surgery Frank F Ing, Thomas E Fagan, Ronald G Grifka, Sandra Clapp, ... Charles E Mullins ...
The second electrode had the configuration of a rectangular patch or a cup and was positioned over the cardiac apex. First implants of the device were conducted at the Johns Hopkins Hospital in Baltimore in 1980. These devices were not programmable and manufactured on an individual basis. The ...
The specific tissues in which AIS originates has been difficult to discern, as bone and soft tissue components of the spine in human patients appear to develop and function normally, at least superficially. Likewise, although AIS manifests around the adolescent growth spurt, it has been unclear ...
Due to the lack of efficacy of synthetic vascular substitutes in the replacement of small-caliber arteries, vascular tissue engineering (VTE) has emerged as a promising solution to produce viable small-caliber tissue-engineered vascular grafts (TEVG). Previous studies have shown the importance of a...
