Common acid reflux medications linked to increased kidney disease risk

Posted by in category: biotech/medical

Proton pump inhibitors (PPIs), which include well-known brand names Prilosec, Nexium and Prevacid, are among the most commonly prescribed medications in the world. Approximately 10 percent of adults in the United States take these drugs for frequent heartburn, acid reflux and gastroesophageal reflux disease. Given their prevalence, researchers at Skaggs School of Pharmacy and Pharmaceutical Sciences at University of California San Diego mined the FDA Adverse Effect Reporting System (FAERS) database for unexpected consequences of PPI consumption.

In the study, published February 19, 2019 by Scientific Reports, the team found that patients who took PPIs were more likely to experience than people who took histamine-2 receptor antagonists, another form of antacid that treats the same conditions and includes the brands Pepcid and Zantac.

“Post-marketing data collected by the FDA and deposited in the FAERS database allows us to look for potential adverse effects beyond what was found in a clinical trial, which may not have lasted as long or included as much diversity as the FAERS does,” said senior author Ruben Abagyan, Ph.D., professor of pharmacy.

Association between Alzheimer’s and high brain iron to be tested in new clinical trial

Posted by in categories: biotech/medical, neuroscience

A new study published in the journal Molecular Psychiatry is suggesting high iron levels in the brain may fundamentally trigger the progressive neurodegeneration associated with dementia and Alzheimer’s disease. A clinical trial is now underway exploring whether Alzheimer’s-related cognitive decline can be slowed by lowering brain iron levels.

Heart attacks rising among young women, study shows

Posted by in category: biotech/medical

(CNN) — The risk of having a heart attack appears to be rising among young women, according to a new study, and researchers are trying to figure out why.

When analyzed across five-year intervals, the overall proportion of heart attack-related hospital admissions in the United States attributable to young patients, ages 35 to 54, steadily climbed from 27% in 1995–99 to 32% in 2010–14, with the largest increase observed in young women, according to the study, published recently in the journal Circulation.

During those periods, there was a rise in these admissions from 21% to 31% among young women, compared with 30% to 33% among young men, the study showed.

A CRISPR Gene Therapy for Hutchinson-Gilford Progeria

Posted by in categories: biotech/medical, genetics, life extension

Researchers at the Salk Institute have moved a step closer to a possible therapy for Hutchinson-Gilford progeria syndrome, a rare genetic disorder that is often described as accelerated aging, as people with it appear to age far faster than normal. Using a new CRISPR/Cas9 gene therapy in a mouse model, they were able to slow down the pace of the condition, improve health, and increase lifespan.

What is Hutchinson-Gilford progeria?

Progeria is a degenerative disorder caused by a mutation in the LMNA gene. This disease has an early onset and progresses rapidly, and animals and humans with progeria show symptoms that are similar to regular aging, only on a much-accelerated timescale, giving them drastically shorter lifespans than normal. Humans with this condition rarely live very long, with the average being only 13 years old.

We are happy to announce Dr. Laura Niedernhofer and Dr. Paul Robbins, University of Minnesota, as speakers for the 2019 Undoing Aging Conference

Posted by in categories: biotech/medical, life extension

“Paul and Laura have made huge contributions to the biomedical gerontology field in recent years. Their work focuses on the characterisation and alleviation of the aspects of aging that are driven by DNA damage. At UA2019, their talks will describe their recent advances in the mechanistic understanding of DNA damage, aided by spectacularly good mouse models, and also their identification of natural products with potent senolytic activity”, says Aubrey de Grey.

Your brain needs a fitness plan. Here’s how to keep it in shape

Posted by in categories: biotech/medical, food, health, neuroscience

This article is reprinted by permission from NextAvenue.org.

The basics of heart health have been drilled into our brains: Eat less saturated fat. Keep moving. Know your “numbers” for cholesterol, blood pressure and BMI.

But what about that brain itself? Although life expectancy has more than doubled since 1900, our “mindspan” — how long we stay cognitively healthy — hasn’t kept pace.

First human gene therapy surgery attempts to halt common form of vision loss

Posted by in category: biotech/medical

In an extraordinary milestone procedure, scientists in the UK have performed the first gene therapy operation aimed at stopping progression of the most common cause of vision loss. The success of the procedure is yet to be determined, however the scientists suggest this one-off operation could be performed early in the degeneration process and essentially halt the disease in its tracks.

Hypoimmunogenic derivatives of induced pluripotent stem cells evade immune rejection in fully immunocompetent allogeneic recipients

Posted by in category: biotech/medical

Autologous induced pluripotent stem cells (iPSCs) constitute an unlimited cell source for patient-specific cell-based organ repair strategies. However, their generation and subsequent differentiation into specific cells or tissues entail cell line-specific manufacturing challenges and form a lengthy process that precludes acute treatment modalities. These shortcomings could be overcome by using prefabricated allogeneic cell or tissue products, but the vigorous immune response against histo-incompatible cells has prevented the successful implementation of this approach. Here we show that both mouse and human iPSCs lose their immunogenicity when major histocompatibility complex (MHC) class I and II genes are inactivated and CD47 is over-expressed. These hypoimmunogenic iPSCs retain their pluripotent stem cell potential and differentiation capacity. Endothelial cells, smooth muscle cells, and cardiomyocytes derived from hypoimmunogenic mouse or human iPSCs reliably evade immune rejection in fully MHC-mismatched allogeneic recipients and survive long-term without the use of immunosuppression. These findings suggest that hypoimmunogenic cell grafts can be engineered for universal transplantation.
