Broken bones will produce many new cells (细胞) and tiny blood vessels (血脉). These cover both ends of the broken part and close up the break until the bone is as whole and strong as before. 【小题1】Which of the following is the best title for the passage? A.How to Know if ...
We found that development of microvessels from actively proliferating rat brain microvessels endothelial cells was greatly modified by the presence of lactate at the surface of the scaffold with different lactate-releasing ability. Fractal dimension of newly-established vessel loops allows precise ...

on designing an "anastomotic coupler" to bind tinyblood vesselsonly millimeters in diameter. Guo said the current surgical process is "very tedious, technically demanding, and error prone" because doctors must carefully hand-sew sutures thinner than hair follicles, and each vessel could take ...
The researchers created a microfluidic system that mimics the blood vessels surrounding tumors. The channel is between 50 and 200 microns wide, and lined with a gel that has holes to simulate the broken blood vessels near tumors. They applied magnetic fields to the robot, making the helix rotat...
In the human body, capillaries are the smallest blood vessels. They are important conduits for the transfer of oxygen and nutrients from the blood stream to tissues, in exchange for carbon dioxide and waste products. Human capillaries are so narrow that red blood cells pass through them one-by...
The miniaturized robot can pass through narrow blood vessels and intricate systems without compromising on speed or maneuverability, neither losing control of the moving direction. The deformations can be "programmed" in advance without sensors or actuators, allowing the robot automatically morphing into ...

She has a condition called Patent Ductus Arteriosus, or PDA, with congestive heart failure, according to Paws Across Pittsburgh. The condition, defined by the Mayo Clinic, is "a persistent opening between the two major blood vessels leading from the heart." ...
