Protein that Shrinks Depressed Brains Identified
(New Scientist) – Could preventing the brain shrinkage associated with depression be as simple as blocking a protein? Post-mortem analysis of brain tissue has shown that the dendrites that relay messages between neurons are more shrivelled in people with severe depression than in people without the condition. This atrophy could be behind some of the symptoms of depression, such as the inability to feel pleasure. As a result, drugs that help repair the neuronal connections, like ketamine, are under investigation.
Ebola Outbreak: Death Toll Rises to Over 140 in Liberia, Guinea
(CNN) – A total of 142 deaths have been reported from the Ebola outbreak in Guinea and Liberia, the World Health Organization said. The virus is still limited to the two nations, the World Health Organization said Tuesday, despite rumors of it spreading to other countries. Nineteen suspected cases reported in Sierra Leone tested negative for the virus, it said.
Almost Blind Michigan Man ‘Seeing Something New Every Day’ Thanks to New Retina Procedure
(Associated Press) – A degenerative eye disease slowly robbed Roger Pontz of his vision. Diagnosed with retinitis pigmentosa as a teenager, Pontz has been almost completely blind for years. Now, thanks to a high-tech procedure that involved the surgical implantation of a “bionic eye,” he’s regained enough of his eyesight to catch small glimpses of his wife, grandson and cat.
FDA Discourages Use of Tissue-Shredding Tool
(Nature) – The US Food and Drug Administration (FDA) has suggested that surgeons refrain from using tissue-grinding tools to remove uteruses or uterine growths because they increase the risk of spreading undetected cancer. It has also instructed manufacturers to review the labelling of the devices, known as morcellators, and is considering requiring a ‘black box’ warning, the strongest warning it can mandate.
HIV Turns 30 Today
(ABC News) – It’s been 30 years since scientists announced the cause of AIDS: a shifty retrovirus that would come to be known as HIV. More than 1,750 Americans had already died from the rare infections and cancers caused by the human immunodeficiency virus, health officials said at the time, and another 2,300 people were living with AIDS.
Fighting Words Are Rarer among British Doctors
(New York Times) – People working in health care there have been discussing military imagery for a decade, said Elena Semino, head of linguistics at the university. “There’s a lot of awareness that battle metaphors can be very harmful to patients,” she told me. “Professionals are conscious of the problems, and they’re advised not to use them.” Instead, British public health leaders and medical practitioners are more apt to talk about the end of life as a “journey” instead of a war, with “pathways” and “steps” instead of fights and weapons.
Senate Passes End-of-Life Planning Bill
(Yale Daily News) – The Connecticut Senate passed a bill on Thursday that, with House approval, would create a system for terminally ill people to declare their wishes for end-of-life care. The Medical Orders for Life-sustaining Treatment (MOLST) bill, which passed the Senate with a unanimous vote, would create a two year pilot program in two different locations in the state for people with terminal illnesses to discuss with healthcare providers how much treatment they want, from limited care to life-support treatment.
Reprogrammed Cells Kept Bug-Free by SIRT1
(Genetic Engineering & Biotechnology News) – Regenerative medicine—the promise of rejuvenating or replacing damaged or diseased tissues—will most likely rely on the use of induced pluripotent stem (iPS) cells, which are obtained when adult cells are essentially thrown into evolutionary reverse. This abrupt change can be hard on cells, which may suffer chromosomal abnormalities and DNA damage. And so the bright vistas of regenerative medicine are shadowed by a stubborn cloud—the uncertainty thatstem cells that are derived from adult cells are really safe.
Let’s Get a Medical Tourism Certificate! Is It Worth the Paper It’s Printed On?
(IMTJ) – A new industry is developing around the business of medical tourism. It’s the certification business. You need an impressive sounding name, a web site, a decent laser printer (and a good relationship with a certificate framing service!). There’s a plethora of “get rich quick” certifications which are appearing around medical tourism. They are quick and easy to obtain.
New Patenting Guidelines Are Needed for Biotechnology
(Phys.org) – Biotechnology scientists must be aware of the broad patent landscape and push for new patent and licensing guidelines, according to a new paper from Rice University’s Baker Institute for Public Policy. Published in the current issue of the journal Regenerative Medicine, the paper is based on the June 2013 U.S. Supreme Court ruling in the case Association for Molecular Pathology (AMP) v. Myriad Genetics that naturally occurring genes are unpatentable. The court case and rulings garnered discussion in the public about patenting biological materials.
More than One-Quarter of Morning-after Pills in Peru Don’t Work
(Washington Post) – A study has found that more than a quarter of emergency contraception pills sold in Peru do not work. Some of the pills were defective while others were just plain fake. Women rely on emergency contraception to prevent pregnancy after having unprotected sex, or when other birth control methods fail, such as when a condom breaks during sex.
Non-Enzyme Nanotechnology Sensor to Detect Blood Sugar
(Nanowerk News) – Researchers at University of Tehran produced a very highly sensitive sensor to measure the amount of blood sugar (“Highly Stable and Selective Non-Enzymatic Glucose Biosensor Using Carbon Nanotubes Decorated by Fe3O4 Nanoparticles”). The newly-invented sensor has applications in foodstuff and medical industries to measure the concentration of glucose in samples.
