Artificial placenta created in the laboratory

Posted on Updated on

This is incredible to know about the placenta. the placenta is the most important part of pregnancy. I wish they had this discovery before.
It’s fine now we all know. I had complete placenta previa.
Since then really wanted to know more aggressively about new researches regarding placenta:)

Artificial placenta created in the laboratory
Complex substance exchange between mother and child
“The transport of substances through biological membranes plays an important role in various areas of medicine”, says Prof. Aleksandr Ovsianikov of the Institute of Materials Science and Technology at TU Wien. “These include the blood-brain barrier, ingestion of food in the stomach and intestine, and also the placenta.”
The placenta protects the infant by filtering out harmful substances while allowing others to pass through with ease. The Austrian scientists have now mimicked the natural processes that created the placenta with the help of novel, laser-based 3D printing process. The researchers claimed the artificial material is the closest scientists have come to replicating the fundamental human organ. Professor Aleksandr Ovsianikov, Institute of Materials Science and Technology in Vienna, said the placenta is a vital element of the human body. The expert said: “The transport system of substances through biological membranes plays an important role in various areas of medicine. “These include the blood-brain barrier, ingestion of food in the stomach and intestine, and also the placenta.”

The bone repairing with 3D Print

Posted on

The bone repairing is very important. Due to the age and other factors, bones suffer from bone defects and disorders.
According to the Journal of Materials Chemistry,”The aim of this study is to set out to solve these problems by applying a modified 3D-printing method to prepare highly uniform CS scaffolds with controllable pore structure and improved mechanical strength. The in vivo osteogenesis of the prepared 3D-printed CS scaffolds was further investigated by implanting them in the femur defects of rats. The results show that the CS scaffolds prepared by the modified 3D-printing method have uniform scaffold morphology. The pore size and pore structure of CS scaffolds can be efficiently adjusted. The comprehensive strength of 3D-printed CS scaffolds is around 120 times that of conventional”.

Cleft lip surgery using 3D Printing

Posted on Updated on

My Father In-law was the famous surgeon for doing cleft lip surgery. According to the Scientific Reports volume,”Computer-aided design and computer-aided manufacturing (CAD/CAM) technology have been implemented in the treatment of cleft lip and palates (CLP) by several research groups. This pilot study presents a technique that combines intraoral moulding with a semi-automated plate generation and 3D-printing”.

3D Printed device for injured spinal cords

Posted on Updated on

According to Ann Parr, M.D., PhD., a co-author of the study and University of Minnesota Medical School Assistant Professor in the Department of Neurosurgery and Stem Cell Institute,”This is a very exciting first step in developing a treatment to help people with spinal cord injuries. Currently, there aren’t any good, precise treatments for those with long-term spinal cord injuries.”

3D printing to understanding Influenza virus

Posted on Updated on

According to Dr Strappe he is working as Senior Lecturer in Medical Laboratory Science at CQUniversity for 20 years’ in Molecular Virology, “The CQUni has a state-of-the-art 3D printing facility which is largely used for engineering applications, however, the Medical students will use this technology to begin to understand concepts about how viruses are formed and enter cells, and how parts of the virus can be targets for therapeutic intervention.
Viruses cannot be seen with the naked eye and working with pathogenic viruses is untenable for undergraduates. 3D printing allows scaling up of the structure of these viruses so students can learn more about virus structure and shape, and relate these features to pathogenesis and recent outbreaks. For example, we are in the middle of a flu epidemic and from printing a high-resolution influenza virus we can highlight the part of the virus (haemmagluttin) that changes every year, causing new outbreaks and the need for annual vaccination. This project exposes medical science students to engineering concepts such as computer-aided design and advanced manufacturing, which they normally wouldn’t encounter in their degree. This helps students to think beyond the confines of their own subject and develop interdisciplinary skills which students will need in the field.”

3D bio-printed scaffolds to help regenerate damaged peripheral nervous systems

Posted on Updated on

According to The Universities spokesperson Liqun Ning and Daniel Chena, they are the postdoctoral fellow in the Tissue Engineering Research Group at the University of Saskatchewan,” They spent the last few years investigating how 3D bio-printing can be used to help with nerve cell regeneration. His solution involves combining engineering and biomedicine in order to create scaffolds that can guide the growth of nerve cells across large damaged areas.

The background is actually mechanical engineering, but tissue engineering is the combination of engineering and biomedicine together. The very beginning of their PhD study, they use their knowledge, background and provide techniques to help people in the biomedical area. The peripheral nervous system, which controls the body beyond the brain and the spinal cord, can be damaged by poor diet, toxins, and trauma. It can also be damaged by diseases such as diabetes, which affects about 422 million people worldwide, and 3.4 million people in Canada”.

3D Printing for Humanity

Posted on Updated on

According to 3D Printing for Humanity, The Santa Clara University’s Department of Bioengineering Assistant Professor Prashanth Asuri and students Sabrina Cismas, Jeffrey Kunkel, William Leineweber, Casey O’Brien, and Mallory Williams,” how engineers are using 3D printing to mitigate the negative side effects of cancer treatment on patients by delivering a pro-drug (a biologically inactive, nontoxic agent that can be metabolized to create a drug) to the entire body and then implanting 3D bioprinted enzymes near the site of the tumor to catalyze the pro-drug into a biologically active chemical compound that will kill the cancerous cells in that particular area without harming the rest of the body. The experiment was well received and the kids asked a lot of good questions—some about how this is being done now, which is hard to answer since the process is still in research; but they were engaged and grasping the concept”.
