Children born after mothers hormonal fertility treatment have increased risk of mental disorders

Whether a child is conceived naturally or in a Petri dish in an incubator has no bearing at all on the child's mental health. However, researchers have identified a small but increased risk of developing a mental disorder such as autism, ADHD or behavioural problems in children whose mothers only received medical treatment to stimulate ovulation and egg development before insemination.

Human gene expression mechanism opens new therapeutic strategies against neurological disease

In a study that could change the way scientists view the process of protein production in humans, University of Chicago researchers have found a single gene that encodes two separate proteins from the same sequence of messenger RNA.

Study: Different strains of alpha-synuclein may contribute to different types of brain diseases

It only takes one bad apple to spoil the bunch, and the same may be true of certain proteins in the brain. Studies have suggested that just one rogue protein (in this case, a protein that is misfolded or shaped the wrong way) can act as a seed, leading to the misfolding of nearby proteins.

State highlights: Calif. bill to fine firms with workers on Medi-Cal fails; Pa. eyes disallowing apologies used against doctors in court-proceedings

A California proposal to fine large companies that have workers on Medi-Cal came up short in an initial vote in the Assembly amid strong business opposition. The proposed fines could reach about $5,000 per full-time employee who receives Medi-Cal, the state Medicaid program for the poor. The bill, AB 880, garnered 46 votes in the 80-member chamber Thursday, short of the 54 votes, or two-thirds majority, needed. The measure could come up for reconsideration as early as next week (Terhune, 6/27).

Scientists find new links in gene networks that control movement

The idea that worms can be seen as waveforms allowed scientists at Rice University to find new links in gene networks that control movement.

New chemical probe confirms that hydrogen sulfide is generated by body's growing cells.

A new study confirms directly what scientists previously knew only indirectly: The poisonous "rotten egg" gas hydrogen sulfide is generated by our body's growing cells.

Mount Sinai researchers produce cells that resemble hematopoietic stem cells

By transferring four genes into mouse fibroblast cells, researchers at the Icahn School of Medicine at Mount Sinai have produced cells that resemble hematopoietic stem cells, which produce millions of new blood cells in the human body every day.

Scientists discover how Arc protein helps translate learning into memory

Scientists at the Gladstone Institutes have deciphered how a protein called Arc regulates the activity of neurons-providing much-needed clues into the brain's ability to form long-lasting memories. These findings, reported today in Nature Neuroscience, also offer newfound understanding as to what goes on at the molecular level when this process becomes disrupted.

Researchers find way to differentiate iPSCs into mature human neurons in the brain

Difficult-to-study diseases such as Alzheimer's, schizophrenia, and autism now can be probed more safely and effectively thanks to an innovative new method for obtaining mature brain cells called neurons from reprogrammed skin cells. According to Gong Chen, the Verne M. Willaman Chair in Life Sciences and professor of biology at Penn State University and the leader of the research team, "the most exciting part of this research is that it offers the promise of direct disease modeling, allowing for the creation, in a Petri dish, of mature human neurons that behave a lot like neurons that grow naturally in the human brain."

Researchers reprogramming skin cells into brain cells to understand Alzheimer's disease

Sam Gandy, MD, PhD, of the Icahn School of Medicine at Mount Sinai is leading an international team of researchers working to reprogram skin cells into brain cells to gain a better understanding of Alzheimer's disease.

Bitter melon juice restricts ability of pancreatic cancer cells to metabolize glucose

A University of Colorado Cancer study published this week in the journal Carcinogenesis shows that bitter melon juice restricts the ability of pancreatic cancer cells to metabolize glucose, thus cutting the cells' energy source and eventually killing them.

Drugs that inhibit buildup of acylcarnitines may block axonal degeneration

Anyone whose hand or foot has "fallen asleep" has an idea of the numbness and tingling often experienced by people with peripheral nerve damage. The condition also can cause a range of other symptoms, including unrelenting pain, stinging, burning, itching and sensitivity to touch.

Knockdown or deletion of Jmjd3 gene could improve efficiency of stem cell conversion process

The removal of a genetic roadblock could improve the efficiency of converting adult cells into stem cells by 10 to 30 times, report scientists from The Methodist Hospital Research Institute and two other institutions in the latest issue of Cell.

UPC develops new system for electroporation of cell cultures

Researchers from the Polytechnic University of Catalonia have developed a technique that improves and cuts the cost of a technique called electroporation, which involves opening pores in cell membranes using an electric field to introduce substances like drugs and DNA. Current methods are aggressive and expensive whereas the new system manages to apply low voltage electroporation with a small printed circuit board, which costs less than a Euro per unit and does not damage cells.

Scientists use magnetic levitation to make in vitro lung tissue more realistic

In a development that could lead to faster and more effective toxicity tests for airborne chemicals, scientists from Rice University and the Rice spinoff company Nano3D Biosciences have used magnetic levitation to grow some of the most realistic lung tissue ever produced in a laboratory.

Exposure of human f-tal testicles to bisphenol A reduces testosterone production

Bisphenol A (BPA) is a chemical compound that is included in the composition of plastics and resins. It is used, for example, in the manufacture of food containers such as bottles and babies' feeding bottles. It is also found in the protective films used inside food and drink cans and on till receipts where it used as a discloser. Significant levels of BPA have also been found in human blood, urine, amniotic fluid and placentas.

Study finds key association between Kallikrein 6 and malignant tumors

One of the most common types of brain tumors in adults, glioblastoma multiforme, is one of the most devastating. Even with recent advances in surgery, radiation and chemotherapy, the aggressive and invasive tumors become resistant to treatment, and median survival of patients is only about 15 months. In a study published in Neuro-Oncology, researchers at Mayo Clinic identify an important association between the naturally occurring enzyme Kallikrein 6, also known as KLK6, and the malignant tumors.
