Androgens more important for ovarian development, study suggests

Scientists have discovered that the male "androgen" hormone is an important element in the ovarian development of female chicken embryos, more so than in the development of male testes.

Swedish researchers prove that 3D bioprinted human cartilage cells can be implanted

Swedish researchers at Chalmers University of Technology and Sahlgrenska Academy have successfully induced human cartilage cells to live and grow in an animal model, using 3D bioprinting.

Postnatal depression in dads

Latest research suggests that 1 in 10 dads will suffer from postnatal depression (PND), and as many as 1 in 7 women will be diagnosed. This was from a survey by NCT released in 2015. This also revealed that as many as 38% of new dads have concerns surrounding their mental health.

Analysis of antibodies could be new tool for predicting prognosis and choosing therapy for RA patients

In rheumatoid arthritis, antibodies are formed that affect the inflammation in the joints. In an article published today in the journal Annals of the Rheumatic Diseases, researchers at Uppsala University show that antibodies against the cartilage protein collagen II are associated with a good prognosis.

Intratumoral vaccination prolongs survival in mouse model of early stage resected pancreatic cancer

Building on their previous research focusing on vaccination within a tumor (intratumoral) for the most common form of pancreatic cancer, investigators from Rutgers Cancer Institute of New Jersey and Rutgers Robert Wood Johnson Medical School have shown that in a mouse model of early stage resected pancreatic cancer, intratumoral vaccination induces an anti-tumor response that results in a significant improvement in overall survival.

Scientists identify molecule that could be targeted to prevent vision loss in diabetics and preterm infants

Researchers at Bascom Palmer Eye Institute, part of the University of Miami Miller School of Medicine, have identified a new molecule that induces the formation of abnormal blood vessels in the eyes of diabetic mice.

Stanford researchers understand how neural networks in the brain form associations

In the decades following the work by physiologist Ivan Pavlov and his famous salivating dogs, scientists have discovered how molecules and cells in the brain learn to associate two stimuli, like Pavlov's bell and the resulting food.

Researchers develop novel genetic score to calculate age-specific risk of Alzheimer's disease

An international team of scientists, led by researchers at University of California San Diego School of Medicine and University of California San Francisco, has developed a novel genetic score that allows individuals to calculate their age-specific risk of developing Alzheimer's disease (AD), based upon genetic information.

New genetic biomarker for colon cancer may lead to development of personalized treatment

Researchers at Baylor Scott & White Research Institute identified a new genetic biomarker for colon cancer that may lead to development of more targeted treatment of the disease.

Researchers examine potential for microRNAs to detect gastrointestinal cancer in blood, bodily fluids

Blood tests that could detect cancer before it develops show promise for the future of screening and prevention, though researchers continue to test which cancer clues are good markers for diagnosis.

Penn researcher receives $16.3 million NIAID grant to develop long-sought-after HIV vaccine

Building on earlier work in designing chimeric human-simian immunodeficiency viruses (SHIVs) that serve as a model of HIV infection of humans, George M. Shaw, MD, PhD, a professor of Hematology/Oncology and Microbiology in the Perelman School of Medicine at the University of Pennsylvania, has received $16.3 million over five years from the National Institute of Allergy and Infectious Diseases to develop a long-sought-after HIV vaccine.

UCLA study traces Pavlovian response to small cluster of brain cells

In his famous experiment, Russian scientist Ivan Pavlov rang a bell each time he fed his dogs. Soon, the dogs began drooling in anticipation when they heard the bell, even before food appeared.

Study identifies urinary biomarker that may help monitor progression of ALS

A study in Neurology suggests that analyzing levels of the protein p75ECD in urine samples from people with amyotrophic lateral sclerosis (ALS) may help monitor disease progression as well as determine the effectiveness of therapies.

Heroin use linked to epigenetic alterations in the brain

Heroin use is associated with excessive histone acetylation, an epigenetic process that regulates gene expression, and more years of drug use correlate with higher levels of hyperacetylation, according to research conducted at The Icahn School of Medicine at Mount Sinai and published in the journal Biological Psychiatry.

Machine learning helps researchers uncover cellular control networks

The flow of information between cells in our bodies is exceedingly complex: sensing, signaling, and influencing each other in a constant flow of microscopic engagements. These interactions are critical for life, and when they go awry can lead to the illness and injury.

Researchers find new way to expand, preserve cord-blood cells as potential treatment for Type 1 diabetes

For parents, storing their newborn baby's umbilical cord blood is a way to preserve potentially lifesaving cells. Now, a group of University of Florida Health researchers has found a way to expand and preserve certain cord-blood cells as a potential treatment for Type 1 diabetes.

Study: Unsaturated fatty acid metabolism associated with progression of Alzheimer's disease

A new study published in PLOS Medicine's Special Issue on Dementia has found that the metabolism of omega-3 and omega-6 unsaturated fatty acids in the brain are associated with the progression of Alzheimer's disease.

RUB researchers identify new rare muscle disorder

A new rare muscle disorder has been identified by researchers at Ruhr-Universität Bochum. This hereditary disease is caused by a defect in the BICD2 gene that manifests itself in altered cellular transport processes in skeletal muscle cells.

PHD2-knockdown overcomes breast cancer cell death in response to glucose starvation

B55α is one of the regulatory subunits of the PP2A phosphatase. This phosphatases has been associated to the control of many biological functions but the multiplicity of complexes that can be formed by the combination of different subunits renders this protein hard in its understanding.

SPECT imaging may not be suitable for monitoring Parkinson's disease, study shows

When monitoring Parkinson's disease, SPECT imaging of the brain is used for acquiring information on the dopamine activity. A new study conducted in Turku, Finland, shows that the dopamine activity observed in SPECT imaging does not reflect the number of dopamine neurons in the substantia nigra, as previously assumed.
