Short bursts of radiation therapy dramatically enhanced the efficiency of targeting glioblastomas with natural nanoparticle-based immunotherapy, thus suppressing growth of the deadly tumor, inducing anti-tumor immunity and prolonging survival in animal models, a research team at Massachusetts General Hospital (MGH) has discovered. The combined strategy, described in ACS Nano, usesContinuar Leyendo

In cancer research, it has long been known that lactic acid, or lactate, is produced in large quantities by cancer cells and that this lactic acid disrupts our defence against tumours. Until now, however, we did not know exactly how this happens. Prof Jo Van Ginderachter, immunologist and cancer researcherContinuar Leyendo

A Zika virus vaccine candidate is effective at preventing the Zika virus passing from mother to fetus in preclinical animal studies, according to a new study in the journal npj Vaccines. San Antonio, Jan 28, 2022.- The research is a collaboration between Trudeau Institute, Texas Biomedical Research Institute’s Southwest NationalContinuar Leyendo

The gene of the brain-derived neurotrophic factor (BDNF) is associated with several processes related to memory and brain plasticity. Now, a paper reveals that it is easier to alter the cognitive activity through transcranial magnetic stimulation (TMS) in people with the genetic variant Val/Val for the BDNF gene. Barcelona, JanContinuar Leyendo

Scientists at Northwestern Medicine and The University of Texas MD Anderson Cancer Center have identified natural nano-bubbles containing the ACE2 protein (evACE2) in the blood of COVID-19 patients and discovered these nano-sized particles can block infection from broad strains of SARS-CoV-2 virus in preclinical studies. Evanston, Jan 24, 2022.- TheContinuar Leyendo

Researchers at the Wayne State University School of Medicine and the National Institutes of Health’s Perinatology Research Branch in Detroit have found that SARS-CoV-2, the virus that causes COVID-19, may cause fetal inflammation even in the absence of placental infection. Detroit, Jan 20, 2022.- Pregnant women have a higher riskContinuar Leyendo

Researchers from Case Western Reserve University have identified a new mechanism by which a protein known for repairing damaged DNA also protects the integrity of DNA by preserving its structural shape. Cleveland, Jan 20, 2022.- The discovery, involving the protein 53BP1, offers insight into understanding how cells maintain the integrityContinuar Leyendo

In a new study, scientists at the University of Missouri demonstrate the direct transmission of bisphenol A (BPA) from a mother to her developing child via the placenta could negatively impact fetal brain development. Cheryl Rosenfeld, a professor of biomedical sciences in the College of Veterinary Medicine, and colleagues proposeContinuar Leyendo

Researchers have used MRI imaging to map visual brain activity in stroke survivors with sight loss that gives new hope for rehabilitation and recovery. Nottingham, Jan 10, 2022.- Scientists from the University of Nottingham have revealed new insights by combining data from clinical sight tests with brain imaging to preciselyContinuar Leyendo

A trial by the University of Eastern Finland found that taking a much higher dose of vitamin D than recommended for five years did not affect total mortality or the incidence of cardiovascular disease or cancer in older men and women. Joensuu/Kuopio, Jan 07, 2022.- In population studies, low levelsContinuar Leyendo
