Researchers remake brain and gut stem cells to study potential therapies for fatal diseases

Research scientists have developed a novel method to re-create brain and intestinal stem cells from patients who died decades ago, using DNA from stored blood samples to study the potential causes of debilitating illnesses such as inflammatory bowel disease.

Researchers find way to prevent noise-induced hearing loss

Researchers from Weill Cornell Medical College and the Gladstone Institutes have found a way to prevent noise-induced hearing loss in a mouse using a simple chemical compound that is a precursor to vitamin B3. This discovery has important implications not only for preventing hearing loss, but also potentially for treating some aging-related conditions that are linked to the same protein.

Aging astrocytes lose ability to protect motor neurons, reveal Cedars-Sinai ALS researchers

Lou Gehrig's disease, also known as amyotrophic lateral sclerosis, or ALS, attacks muscle-controlling nerve cells – motor neurons – in the brain, brainstem and spinal cord, leading to progressive weakness and eventual paralysis of muscles throughout the body. Patients typically survive only three to five years after diagnosis.

USC scientists find new way to suppress obesity

Imagine being able to take a pill that lets you eat all of the ice cream, cookies, and cakes that you wanted – without gaining any weight.

UCLA research may lead to novel treatment for PH1

Research by UCLA biochemists may lead to a new treatment - or even a cure - for PH1, a rare and potentially deadly genetic kidney disease that afflicts children. Their findings also may provide important insights into treatments for Parkinson's disease, Alzheimer's disease and other degenerative diseases.

Rare mutation in suspect gene disrupts brain circuitry in complex psychiatric disorders

Researchers have long suspected that major mental disorders are genetically-rooted diseases of synapses - the connections between neurons.

Scientists create computer algorithm for cell and tissue engineering

In a boon to stem cell research and regenerative medicine, scientists at Boston Children's Hospital, the Wyss Institute for Biologically Inspired Engineering at Harvard University and Boston University have created a computer algorithm called CellNet as a "roadmap" for cell and tissue engineering, to ensure that cells engineered in the lab have the same favorable properties as cells in our own bodies.

Bioengineers create 3D brain-like tissue to study chemical and electrical changes

Bioengineers have created three-dimensional brain-like tissue that functions like and has structural features similar to tissue in the rat brain and that can be kept alive in the lab for more than two months.

Antifungal drug resistance evoked through RNAi-dependent epimutations

Microorganisms like bacteria and fungi can evade treatment by acquiring mutations in the genes targeted by antibiotics or antifungal drugs.

BU researchers find possible way to prevent Alzheimer's disease

Boston University School of Medicine researchers may have found a way to delay or even prevent Alzheimer's disease (AD). They discovered that pre-treatment of neurons with the anti-aging protein Klotho can prevent neuron death in the presence of the toxic amyloid protein and glutamate.

Research findings provide promising news for couples considering in-vitro fertilization

Using computer-automated, time‐lapse photography of embryos in the laboratory during in-vitro fertilization may improve embryo selection, potentially increasing the chances of pregnancy among women undergoing the procedure, according to new research from the Perelman School of Medicine at the University of Pennsylvania and five other fertility centers.

Viewpoints: Overlooked costs for insurers; Medicaid disparities; dropping doctors from Medicare Advantage

In a Think Tank post Thursday, I wrote about how insurers deciding to participate next year in the health exchanges established under Obamacare could be expecting funds that the federal government may not have legal authority to disburse. But that's not the only potential pitfall for carriers: They could also end up on the hook for payment reductions caused by sequestration (Chris Jacobs, 6/23).

New concept of organs on a chip may help study cancer metastasis

The recent development of the concept of organs on a chip opens the possibility of realistically studying human organs without the use of patients or animal testing.

Researchers identify new mechanism by which normal cells turn malignant in mammary epithelial tissues

A team of researchers led by David J. Mooney, Robert P. Pinkas Family Professor of Bioengineering at the Harvard School of Engineering and Applied Sciences, have identified a possible mechanism by which normal cells turn malignant in mammary epithelial tissues, the tissues frequently involved in breast cancer.

Using placental cells to repair damaged tissues: an interview with Zami Aberman, CEO, Pluristem Therapeutics

We start with birth and we collect the cells after C-section. The reason for that is we have to have the mother sign a consent letter that she is donating the placenta and, on top of that, we have to have a blood sample from the mother to test for any viral contamination.

Researchers create three-dimensional complement of human retinal tissue in a dish

Using a type of human stem cell, Johns Hopkins researchers say they have created a three-dimensional complement of human retinal tissue in the laboratory, which notably includes functioning photoreceptor cells capable of responding to light, the first step in the process of converting it into visual images.

Ultrasound beam 'tweezers' can grip and manipulate tiny clusters of cells

Pioneering 'tweezers' that use ultrasound beams to grip and manipulate tiny clusters of cells under electronic, push-button control could lead to life-changing medical advances, such as better cartilage implants that reduce the need for knee replacement operations.
