Delft University of Technology's "Bio-inspired" research team developed a life-saving catheter based on a 3D printed human heart model. The team is led by engineer Awaz Ali, who collaborated with 3D printing company Materialise to make a heart model, and now they are testing the catheter. They provide a large number of sensors for 3D printed heart models based on real-world data, so any contact between the catheter and the model surface can be reflected. The newly developed catheter, with "improved mobility," opens the door to catheter heart surgery. Ali, the engineer behind the project, is currently conducting an experiment to test catheters in three ways through the cardiovascular system. Using a 3D printed heart model allows Ali and her team to record the time it takes to complete each program and analyze the physical and psychological load required to perform various tasks. This information can help to develop more efficient catheters to a large extent. “I think the 3D printing model offers a whole new way to test our instruments so they can be tested in scientifically valid models and easily cope with the need for additional demand,†she said. “The test rig has very fine anatomical structures, such as the heart valve model and the papillary muscles on the ventricular wall. Another important benefit is that we can achieve many additional requirements. For example, the area of ​​the atrial septum, and the local smooth inside of the heart. surface. The new multi-function Sigma catheter is a complex curved shape with a serpentine movement at the tip. It can be turned into S and Z curves, as well as multi-planar curves, which is a huge change for our catheters today. This means that doctors can perform more complex procedures on the catheter rather than having a high-risk surgery.
Food-derived peptide is a new type of protein hydrolyzed product made from edible protein through enzymatic hydrolysis, separation and purification. Food-derived peptides come from a wide range of sources. According to the source of protein raw materials, they can be divided into animal-derived protein peptides and plant-derived protein peptides. Food-derived peptides come from a wide range of sources. According to the source of protein raw materials, they can be divided into animal-derived protein peptides and plant-derived protein peptides [1] . Food-derived peptides are divided into food-derived oligopeptides (molecular weight less than 1 000 Da) and food-derived polypeptides (molecular weight greater than 1 000 Da) according to their relative molecular mass distribution (referred to as molecular weight). Animal protein peptides are more researched on milk protein peptides, marine fish protein peptides, collagen peptides and egg white protein peptides; plant protein peptides are more researched on soybean peptides, corn peptides, wheat peptides, etc.we have Orange Juice Powder,Apple Juice Powder,Mulberry Juice Powder,Blackberry Juice Powder,Seabuckthom Juice Powder,organic garlic powder,organic sea-buckthorn fruit powder,Pomegranate Juice Powder.
