Tensile Material Properties of Human Costal Cartilage Perichondrium
Rib and costal cartilage fractures are the most common injuries resulting from blunt thoracic loading scenarios, including motor vehicle collisions. The costal cartilage is a cylindrical hyaline cartilage composed of two layers: a core interstitial matrix enveloped by the perichondrium. The …

The effects of prolonged mechanical ventilation on the alpha-adrenergic responses of costal diaphragm arterioles
Introduction: Mechanical ventilation (MV) is a life-saving intervention employed in Intensive Care Units worldwide. Previous work has shown a substantial time-dependent reduction in diaphragmatic blood flow and O₂ delivery with MV, likely contributing to diaphragm fatigue and weaning difficulties. …

On the Improvements of Boundary-Layer Representation for High Resolution Weather Forecasting in Costal-Urban Environments
<p>As large urban centers around the world become more densely populated, the global conversion from natural to man-made land surfaces will only increase. These land-use changes affect the urban surface energy budget which in turn changes the structure of the planetary boundary layer (PBL) above. …

Seasonal dynamics in costal aquifers : investigation of submarine groundwater discharge through field measurements and numerical models
The fresh and saline groundwater flowing from coastal aquifers into the ocean comprise submarine groundwater discharge (SGD). This outflow is an important pathway for the transport of nutrients and contaminants, and has been shown to adversely affect coastal ecosystems in many areas of the world. …

Preliminary Investigation of the Mechanical Properties of Costal Cartilage and Costochondral Junction in Three-Point Bending
… The skeletal thorax is composed of the ribs, costal cartilage, thoracic vertebrae, and sternum. Costal cartilage (CC) is a viscoelastic material which connects the ribs to the sternum. Costochondral junctions (CCJ) are primary cartilaginous joints which couple the costal cartilage to the ribs. …

Effects of Sex, Strain Rate, and Age on the Compressive and Tensile Material Properties of Human Costal Cartilage
… and tensile material properties of human costal cartilage over a wide range of subject ages and sexes. Cylindrical compression samples and dog-bone shaped tension samples were tested to failure on a material testing system using target strain rates of 0.005 strain/s and 0.5 strain/s. …

Differential Gene Expression in Response to Hypoxia and Acidosis in Chest Wall Deformities and Chondrosarcoma
<p>The importance of understanding how costal cartilage chondrocytes respond to stimuli such as oxidative stress and low pH has been largely overlooked in studies involving tissue culturing due to major differences between oxygen and pH levels during incubation and the natural environment of …

Transcostal focused ultrasound surgery: treatment through the ribcage
… the clinical application of image-guided transcostal focused ultrasound surgery (FUS) are the organ motion caused by cardiac and respiratory movements and the presence of the ribcage. Intervening ribs absorb and reflect the majority of ultrasound energy excited by an acoustic source, resulting …

Decellularized Cartilage for Airway Repair
… young children often lack sufficiently sized costal cartilage for this procedure, resulting in increased donor site morbidity and operative time, as well as an elevated risk for airway restenosis, necessitating revision surgery. To overcome these limitations, we created a first-of-its-kind …

Serum somatomedin and somatomedin generation by the perfused liver in protein malnourished rats
… punched from slices of immature porcine costal cartilage. The handling of the cartilage discs was made easy by the specially designed incubation rack. Preincubation increased sensitivity of the cartilage, and post incubation with radioactive tracer reduced the potential interference of …
