Some neurological disorders can be improved through photobiomodulation, a non-invasive technique based on the application of low-intensity light to stimulate altered functions in specific regions of the body. Now, a study reveals how photobiomodulation applied to the brain-gut axis is effective in recovering some cognitive alterations and sequelae caused by chronic stress. The study opens up new perspectives for applying the technique in future therapies for the treatment of neurological diseases in patients.

Researchers are on a mission to kill drug-resistant bacteria, and a new study has identified a therapy that can penetrate the slime that such infections use to protect themselves from antibiotics.Researchers have shown that an antimicrobial peptide from cows has potential for treating incurable infections from the bacterium Klebsiella pneumoniae. The bacteria, commonly found in the intestines, is usually harmless. It becomes a health hazard when it enters other parts of the body and can cause pneumonia, urinary tract and wound infections. Those at highest risk include seniors and patients with other health problems such as diabetes, cancer, kidney failure and liver disease.

A new device for taking blood samples uses microneedles and a suction cup instead of a large needle. People with a phobia of needles stand to benefit. More blood can be obtained than with the classic finger prick, making diagnostic measurements more reliable. Because the device can be produced at low cost, it is also suitable for developing countries.

A team has identified a molecular cellular mechanism that is linked to microencephaly, a condition in which a baby's head is much smaller than expected.

Early detection has the potential to transform treatment and outcomes in cancer care, especially for cancers like liver cancer, which is typically diagnosed at a late stage with limited options for cure. A new study suggests that proteins detectable in the blood could improve predictions about risk of liver cancer years before typical diagnosis.

Researchers have identified a causal genetic variant strongly associated with childhood obesity. The study provides new insight into the importance of the hypothalamus of the brain and its role in common childhood obesity and the target gene may serve as a druggable target for future therapeutic interventions.

The team discovered that an essential nutrient called choline is transported into the brain, across the blood-brain barrier, by a protein transporter called FLVCR2. This is discovery will inform future design of drugs for diseases such as Alzheimer's and stroke, mimicking choline so they can be smuggled into the brain.

A simple blood test could allow doctors to determine whether a person may be at higher risk for stroke or cognitive decline during their lifetime, according to a new study.

Anticoagulant treatments are crucial for managing many conditions, such as heart disease, stroke and venous thrombosis. Current options, however, carry an inherent risk of serious bleeding due to trauma or unforeseen events. A team has developed a new anticoagulant, designed to have an on-demand reversible activity, with a fast-acting 'antidote'. This approach could revolutionize the use of anticoagulants in surgery or other applications. The mechanism of activation and deactivation of the active principle could also be used in immunotherapy.

A completely novel way to develop 'surpamolecules' for drug discovery could have application in immunotherapy as well as this breakthrough design for an anticoagulant with on-demand reversibility.

A recently completed study indicates that circulatory protein levels can provide important information for increasingly accurate diagnoses and personalised care in patients with aggressive B-cell lymphoma. Researchers identified a specific protein profile linked to more severe disease.

In unincorporated communities in the United States-Mexico borderlands, historically and socially marginalized populations become invisible to the healthcare system, showing that geography acts as a structural determinant of health for low-income populations.

Researchers have discovered in a preclinical model that cytokines, proteins that control immune response, circulating in maternal blood during pregnancy may mitigate an offspring's risk for psychiatric conditions. The findings are surprising because circulating maternal cytokines are at such low levels that they were not implicated in fetal brain development and offspring behavior before.

A study in more than 3,000 US counties, with 315 million residents, has suggested that air pollution is linked with stress and depression, putting under-65-year-olds at increased risk of dying from cardiovascular disease.

A new tool to identify infants most at risk for severe respiratory syncytial virus (RSV) illness could aid pediatricians in prioritizing children under 1 to receive a preventive medication before RSV season (October-April), according to new research.

An unexpected discovery surprised a scientist: nanometer-sized diamond particles, which were intended for a completely different purpose, shone brightly in a magnetic resonance imaging experiment -- much brighter than the actual contrast agent, the heavy metal gadolinium. Could diamond dust -- in addition to its use in drug delivery to treat tumor cells -- one day become a novel contrast agent used for MRI?
