Team finds how error and reward signals are organized within the cerebral cortex
Posted by Xavier Rosseel in categories: biotech/medical, neuroscience
Psychiatrists diagnose people with schizophrenia, ADHD, bipolar disorder and other mental illnesses by spending time with them, looking for the particular behavior symptoms of each. What follows can be a hit-or-miss series of medications and dosages until disruptive behaviors go away.
By deciphering the circuitry of the medial frontal cortex — an area beneath the top of the head — those diagnoses could become much more efficient and precise by allowing physicians to diagnose based on how neurons respond to a simple series of behavior tests.
A Vanderbilt University team recently described how error and reward signals are organized within the cerebral cortex, which is only as thick as a nickel. They say this information could also be significant in drug development by guiding medications to target receptors in particular layers of the cerebral cortex where they will be most effective.

UNITY Biotechnologies Selects a New Senolytic Candidate
Posted by Steve Hill in categories: biotech/medical, life extension
Another senolytic drug candidate has entered development at Unity Biotechnologies. The purpose of senolytics is to clear the body of harmful senescent cells, which accumulate with age and encourage age-related diseases to develop.
A new treatment for age-related diseases of the eye
Recently, UNITY Biotechnologies announced the selection of a new lead drug, UBX1967, with the goal of treating a range of age-related diseases of the eye. This is the second drug in the pipeline of this $677 million company. This drug is unique in the world of eye treatment; it targets and destroys senescent cells, making it a senolytic that targets one of the root causes of aging to treat disease.

Delivery of 45 Age Reversing Gene Therapies at Once is Under Peer Review
Posted by Montie Adkins in categories: biotech/medical, life extension
George Church revealed progress on aging reversal using gene therapies. They have delivered 45 gene therapies to provide aging reversal. They find the combined treatment is effective against obesity, diabetes, osteoarthritis, cardiac damage and kidney disease.
This is the work that Nextbigfuture has been expecting from George’s company Rejuvenate Bio.

Reduced non–rapid eye movement sleep is associated with tau pathology in early Alzheimer’s disease
Posted by Genevieve Klien in categories: biotech/medical, life extension, neuroscience
In patients with Alzheimer’s disease (AD), amyloid-β (Aβ) plaques and tau protein tangles accumulate in the brain long before the appearance of clinical symptoms. Early intervention is critical for slowing neurodegeneration and disease progression. Therefore, reliable markers of early AD are needed. Lucey et al. analyzed sleep patterns in aging cognitively normal subjects and showed that non–rapid eye movement (NREM) sleep negatively correlated with tau pathology and Aβ deposition in several brain areas. The results show that alterations in NREM sleep may be an early indicator of AD pathology and suggest that noninvasive sleep analysis might be useful for monitoring patients at risk for developing AD.
In Alzheimer’s disease (AD), deposition of insoluble amyloid-β (Aβ) is followed by intracellular aggregation of tau in the neocortex and subsequent neuronal cell loss, synaptic loss, brain atrophy, and cognitive impairment. By the time even the earliest clinical symptoms are detectable, Aβ accumulation is close to reaching its peak and neocortical tau pathology is frequently already present. The period in which AD pathology is accumulating in the absence of cognitive symptoms represents a clinically relevant time window for therapeutic intervention. Sleep is increasingly recognized as a potential marker for AD pathology and future risk of cognitive impairment. Previous studies in animal models and humans have associated decreased non–rapid eye movement (NREM) sleep slow wave activity (SWA) with Aβ deposition. In this study, we analyzed cognitive performance, brain imaging, and cerebrospinal fluid (CSF) AD biomarkers in participants enrolled in longitudinal studies of aging.

Fujifilm plans $20M U.S. facility for burgeoning interest in stem cell treatments
Posted by Genevieve Klien in categories: bioengineering, biotech/medical, genetics
A host of companies are developing regenerative treatments that lean on stem cells. Seeing an opportunity, Japan’s Fujifilm will build a U.S. stem cell manufacturing facility not only for its own efforts but also as a CDMO.
The company said today that its Fujifilm Cellular Dynamics Inc. (FDCI) subsidiary will invest about $21 million to build a facility in Madison, Wisconsin, to “industrialize” induced pluripotent stem cell technologies for its pipeline of regenerative drugs and to manufacture iPS cells for others. It expects the facility to be ready by March 2020.
“To meet the growing demand for FCDI’s iPS cell platform, the state-of-the-art production facility will have a flexible cell culturing design to serve production requirements of both industrial quantities of cells, and small, diverse batches,” Seimi Satake, FCDI CEO, said in a statement. “By combining Fujifilm’s experience gleaned from the intricate process of manufacturing photographic film along with FCDI’s knowledge of cell reprogramming, genetic engineering and cell differentiation, the facility is poised to address the complex manufacturing processes of cell therapies.”

Doctor double act can help you live healthier for longer in their anti-ageing series for the Mail
Posted by Genevieve Klien in categories: biotech/medical, life extension, neuroscience
Today in the Mail’s pullout, the twins focus on anti-ageing your brain, and show you simple strategies to give it a boost — from telling you why you’re becoming forgetful to revealing the techniques you can use to improve brain health and function.
Yes, in the ‘spouse’ seat during counselling was Xand, his identical twin and fellow telly doctor.
It’s quite a revelation that these two — both contenders for the title of TV’s sexiest doctor, surely — have a relationship that might require them even to think of counselling.

Novel Device to Reduce Chemotherapy’s Harmful Side Effects
Posted by Genevieve Klien in category: biotech/medical
The new device, developed by researchers from the University of California in the US, absorbs excess drugs before they spread throughout the body.
For example, doxorubicin, a chemotherapy drug, kills more tumour cells when given at higher doses. However, most patients cannot tolerate large amounts of the drug because it can cause heart failure, among other side effects.
But using the device, excess doxorubicin can be filtered out from the blood at locations outside of the tumour to reduce the harmful effects of the drug on the healthy cells.

San Diego Stem Cell Clinics in National Spotlight
Posted by Genevieve Klien in categories: biotech/medical, futurism
Some see stem cell therapy as the future of medicine, but not all of the treatments have been proven to work. Yet the treatments cost patients tens of thousands of dollars.
NBC 7 Investigates has been looking into stem cell clinics and treatments offered across San Diego County for nearly a year. On Friday, NBC’s Today show featured NBC 7’s work in a report on stem cell treatments.
