First comprehensive characterization of blood-brain, blood-tumor barriers in brain metastases

The human brain has some remarkable capabilities - including the ability to block cancer drugs from effectively reaching cancer cells in the brain.

CHLA researchers discover a mechanism of heart regeneration in zebrafish

One of the reasons coronary heart disease is so deadly is that fluid build-up and scarring can develop in the heart tissue. This prevents the heart from contracting properly, impacting its ability to supply the body with fresh blood. If scarring is extensive, heart failure can result.

Autoimmune attack on uninfected red blood cells may cause anemia in malaria patients

An autoimmune attack on uninfected red blood cells likely contributes to anaemia - a shortage of red blood cells - in people with malaria, according to a new study published in eLife.

Virginia Tech professor wins $1.85 million NIH grant for sepsis research

One drop of blood contains 5,000 neutrophils, the most abundant type of white blood cell that is deployed by the human immune system. Throughout the entire body, a human has 25 billion of these foot soldiers that are relentlessly patrolling to fight invading pathogens.

Cardiac-specific biomarkers may help predict CVD risk factors early

A new review article provides valuable insights into how traditional and emerging cardiac-specific biomarkers and their associated cardiovascular disease (CVD) risk factors may help point to effective preventive interventions in high-risk obese populations starting at an early stage of disease development.

New approach may help kill Mycobacterium tuberculosis

Current treatment regimens for Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis, are long, complex, and hard for people to sustain. Moreover, the bacteria often develop drug resistance, and many people harbor multi-drug-resistant strains. In 2018 alone, nearly 1.5 million people died from tuberculosis worldwide.

Collaborative study shows sex-specific processes in schizophrenia and bipolar disorder

Recent studies have found a high genetic similarity of the psychiatric diseases schizophrenia and bipolar disorder, whose disease-specific changes in brain cells show an overlap of more than 70 percent.

New study sounds a note of caution in using probiotics in ICU

It's become common for patients in the intensive care unit (ICU), both children and adults, to receive probiotics. Often, they are started at home to counteract diarrhea caused by antibiotics. There is also interest in using probiotics proactively in the ICU. A large multicenter clinical trial in Canada is testing whether probiotics would prevent ventilator-associated pneumonia in adult ICU patients.

Understanding neural processes behind motor behaviours and learning

Researchers have provided new insight into the neural processes behind movement and learning behaviours, according to a study published today in eLife.

Protein that drives pancreatic cancer growth could be new treatment target

A protein that drives growth of pancreatic cancer, and which could be a target for new treatments, has been identified by researchers at the Crick.

Scientists identify new mechanism for the development of Parkinson's disease

An international research team including scientists from the University of Cologne have identified a new mechanism for the development of Parkinson's disease, which could prove to be the starting point for the development of a more targeted therapy.

Researchers uncover new and unexploited drug target for childhood cancer

An Australian-led international research effort has broken fresh ground in the race to find more effective treatments for the childhood cancer neuroblastoma, by uncovering a new and as-yet unexploited target in cancer cells that therapeutic drugs can be aimed at.

Maternal pregnancy-related anxiety may affect infant brain responses to sad speech

A study has shown a potential link between pregnancy-related anxiety and how a baby's brains respond to sad speech.

Automated meal detection system brings 'artificial pancreas' one step closer to reality

A.I. researchers at Stevens Institute of Technology have developed a system that can detect when a person is eating and calculate how many carbohydrates they are consuming with unprecedented accuracy and speed.

Two strains of the same bacterium work together to cause deadly flesh-eating disease

Two different strains of the same flesh-eating bacteria species work in combination to become more dangerous.

Popular cancer drug linked to weight gain and increased systolic blood pressure

Contraceptive drug effective in preventing and regressing cervical cancer in mice

A new study in The American Journal of Pathology, published by Elsevier, reports that medroxyprogesterone acetate (MPA), the active ingredient in the common contraceptive injection Depo-Provera, was effective in preventing the development of cervical cancer in mice with precancerous lesions.

Retinal hyperspectral imaging shows promise for early Alzheimer's disease detection

Alzheimer's disease is the leading cause of dementia in the U.S., with approximately 5.4 million currently affected and an estimated 16 million by 2050.

Regulating gut bacteria could calm chemo side effects, reduce cognitive problems

In a new study, scientists observed several simultaneous reactions in mice given a common chemotherapy drug: Their gut bacteria and tissue changed, their blood and brains showed signs of inflammation, and their behaviors suggested they were fatigued and cognitively impaired.
