The human brain makes fructose, researchers discover – here’s why that might be a big deal
Posted by Karen Hurst in categories: biotech/medical, food, neuroscience
Researchers at Yale University have discovered that the brain is capable of making fructose – a simple sugar, usually found in fruit, vegetables and honey.
Not all sugars are equal. Glucose is a simple sugar that provides energy for the cells in your body. Fructose has a less important physiological role and has been repeatedly linked to the development of obesity and type 2 diabetes. When there is excess glucose the processes that break it down can become saturated, so the body converts glucose into fructose instead, using a process known as the “polyol pathway”, a chemical reaction involved in diabetic complications. The researchers at Yale reported in the journal, JCI Insight, that the brain uses the polyol pathway to produce fructose in the brain.

Scientists test deep brain stimulation as potential anorexia therapy
Posted by Karen Hurst in categories: biotech/medical, food, neuroscience
Now this is what I am talking about when brain stimulation can treat disease and disorders were often better off.
LONDON: A small study in 16 people with severe anorexia has found that implanting stimulation electrodes into the brains of patients could ease their anxiety and help them gain weight.
Researchers found that in extreme cases of the eating disorder, the technique — known as deep brain stimulation (DBS) — swiftly helped many of those studied reduce symptoms of either anxiety or depression, and improved their quality of life.

Bioprinter makes fully functional human skin
Posted by Saúl Morales Rodriguéz in categories: 3D printing, bioengineering, bioprinting, biotech/medical, business
Scientists from the Universidad Carlos III de Madrid (UC3M), CIEMAT (Center for Energy, Environmental and Technological Research), Hospital General Universitario Gregorio Marañón, in collaboration with the firm BioDan Group, have presented a prototype for a 3D bioprinter that can create totally functional human skin. This skin is adequate for transplanting to patients or for use in research or the testing of cosmetic, chemical, and pharmaceutical products.
This research has recently been published in the electronic version of the scientific journal Biofabrication. In this article, the team of researchers has demonstrated, for the first time, that, using the new 3D printing technology, it is possible to produce proper human skin. One of the authors, José Luis Jorcano, professor in UC3M’s department of Bioengineering and Aerospace Engineering and head of the Mixed Unit CIEMAT/UC3M in Biomedical Engineering, points out that this skin “can be transplanted to patients or used in business settings to test chemical products, cosmetics or pharmaceutical products in quantities and with timetables and prices that are compatible with these uses.”

Making 3D maps of every cell in the human body
Posted by Klaus Baldauf in categories: biotech/medical, health, neuroscience, virtual reality
On 10 February 2017, the London-based charity Cancer Research UK announced that a team of molecular biologists, astronomers and game designers would receive up to £20 million (US$25 million) over the next five years to develop its interactive virtual-reality map of breast cancers. Currently there are animations for tumor that allow virtual flew throughs. However, they are mock-up. The real models will include data on the expression of thousands of genes and dozens of proteins in each cell of a tumor. The hope is that this spatial and functional detail could reveal more about the factors that influence a tumor’s response to treatment.
The project is just one of a string that aims to build a new generation of cell atlases: maps of organs or tumors that describe location and make-up of each cell in painstaking detail.
Cancer Research UK awarded another team up to £16 million to make a similar tumor map that will focus on metabolites and proteins. Later this year, the US National Institute of Mental Health will announce the winners of grants to map mouse brains in extraordinary molecular detail. And on 23–24 February, researchers will gather at Stanford University in California to continue planning the Human Cell Atlas, an as-yet-unfunded effort to map every cell in the human body.

Scientists Say Induced Hibernation Could Help Us Fight Cancer in the Future
Posted by Shane Hinshaw in category: biotech/medical
Hibernation used in conjunction with radiotherapy could be the key to fighting cancer in the future, according to new research.
Putting cancer patients into a hibernation-like ‘deep sleep’ state could hypothetically slow down their bodily functions and halt the spread of tumours inside their tissues, while also increasing the body’s resistance to radiation, scientists suggest.
The experimental treatment – which is still many years away from being attempted in humans – might sound like science fiction, but does have some grounding in reality.

Cancer cells hijack healthy cells to help them spread to other organs
Posted by Kevin Huang in categories: bioengineering, biotech/medical
An interaction between two proteins enables cancer cells to use the physical forces of healthy cells to start spreading to other parts of the body.
The finding by researchers from the Francis Crick Institute in London and the Institute for Bioengineering of Catalonia (IBEC) in Barcelona is published in the journal Nature Cell Biology.
The process by which cancer cells separate from the original tumour to form new tumours in other organs or tissues of the body is called metastasis, and it is responsible for the majority of deaths in patients with cancer.

This invention by a British student could save millions of lives across the world
Posted by Klaus Baldauf in categories: biotech/medical, innovation
A 22-year-old British student has invented a mobile fridge that could save millions of lives across the world.
Will Broadway’s “Isobar” has been designed to keep vaccines at the ideal temperature while in transit in developing countries.
And Will doesn’t plan to make money from his creation.
