Candy Floss Machines May Be The Future For Making Artificial Organs

For any medical reason, sometimes artificial organs are required to take place instead of the real organ in the human body. But making artificial organs, which have complicated and  intricate structures, aren't easy to make and there have been many methods which have been devised but don't work as efficiently.  Leon Bellan is an assistant professor of mechanical engineering at Vanderbilt University, who has been working with candy floss machines, getting them to spin out networks of tiny threads similar in size, density and complexity to the patterns formed by capillaries - the minuscule, thin-walled vessels that deliver oxygen and nutrients to cells and carry away waste. His main aim has been to make fibre networks that can be used as templates to produce the capillary systems required to create full-scale artificial organs. This research has been published in the Advanced Healthcare Materials  journal. Bellan and his colleagues have been successful in using their

One Paragraph on Diabetes and Psychiatric Disorders

A new report featuring in the February 2016 issue of  The FASEB Journal , scientists show that a gene called "DISC1," is believed to play a role in mental health disorders, such as schizophrenia, bipolar disorder (and other forms of depression); influence the function of pancreatic beta cells which produce insulin to maintain normal blood glucose levels. Understanding how the different mechanisms  of diseases in the body is essential to be able to pick efficient therapies for patients. Bortell and colleagues decided to study the function of DISC1 by comparing 2 groups of mice. The first group was genetically manipulated to disrupt the DISC1 gene only in the mouse's pancreatic beta cells. The second group of mice was normal. The mice with disrupted DISC1 gene showed increased beta cell death, less insulin secretion and impaired glucose regulation while control mice were normal. The researchers found that DISC1 works by controlling the activity of a specific protein (GS
