Exclusive breastfeeding duration and risk of childhood cancers

JAMA Network Open

2024-03-26

(Press-News.org) About The Study: In this cohort study including 309,000 Danish children, longer duration of exclusive breastfeeding was associated with reduced risk of childhood B-cell precursor-acute lymphoblastic leukemia, corroborating results of previous case-control investigations in this field. To inform future preemptive interventions, continued research should focus on the potential biologic mechanisms underlying the observed association.

Authors: Signe Holst Søegaard, Ph.D., of the Danish Cancer Society in Copenhagen, is the corresponding author.

Ancient DNA reveals origin of racial/ethnic disparity in a childhood cancer

2024-03-26

There are 40% more Hispanic/Latino kids diagnosed with acute lymphoblastic leukemia (ALL) than white non-Hispanic/Latino children; actually, Hispanic/Latino individuals have the highest risk of ALL in the United States. However, the basis for this difference is not well understood. Researchers recently identified a genetic variant that accounts for the increased risk of B-cell ALL in Hispanic/Latino children, and using ancient DNA, they traced the mutation all the way back to the first migrants who ...

USC researchers find genetic variant contributing to disparities in childhood leukemia risk

2024-03-26

Acute lymphoblastic leukemia (ALL), the most common childhood cancer, disproportionately affects children of Hispanic/Latino origin in the United States. They are 30-40% more likely to get ALL than non-Hispanic white children, but the exact genetic basis and cause of that increased risk are unknown. Now, a study from the Keck School of Medicine of USC has revealed a key genetic variant contributing towards the increased risk, as well as details about the biological basis of ALL. The team used genetic fine-mapping analysis, a statistical method that allows researchers ...

Structural basis for the regulatory mechanism of mammalian mitochondrial respiratory chain megacomplex-I2III2IV2

2024-03-26

Mammalian mitochondrial electron transport chain complexes are the most important and complicated protein machinery in mitochondria. Although this system has been studied for more than a century, its composition and molecular mechanism are still largely unknown. Here, Yang’s group report the high-resolution cryo-electron microscopy (cryo-EM) structures of porcine respiratory chain megacomplex-I2III2IV2 (MCI2III2IV2) in five different conformations, including State 1, State 2, Mid 1, Mid 2, and Mid 3. High-resolution cryo-EM imaging, combined with super-resolution gated stimulated emission depletion microscopy (gSTED), strongly supports ...

Antifungal activity of a maleimide derivative: Disruption of cell membranes and interference with iron ion homoeostasis

2024-03-26

This study is led by Prof. Ying Li (Xuzhou Medical University), Prof. Zuobin Zhu (Xuzhou Medical University), and Prof. Wenqiang Chang (Shandong University). A small molecule library consisting of 40 compounds, specifically N-substituted maleimide and its derivatives were initially screened in the study. Among them, twelve maleimides, each with a distinct N-protection group, were synthesized using ring-opening and ring-closing reactions involving various amines and maleic anhydride. Additionally, a set of twenty-eight ...

Addressing global energy needs with ideal electrocatalysts 

2024-03-26

Researchers from the University of Tartu and the University of Copenhagen have proposed the theoretical description of an ideal electrocatalysis process, which, if implemented, could double the efficiency of energy conversion and storage devices.  As the world seeks sustainable solutions to meet escalating energy demands, a collaborative team of researchers from the Universities of Tartu and Copenhagen has proposed an innovative approach to overcome long-standing limitations in oxygen electrocatalysis. Oxygen electrocatalysis ...

Researchers identify new way to inhibit immune cells that drive allergic asthma

2024-03-26

Researchers at the Keck School of Medicine, University of Southern California, have discovered that a protein called Piezo1 prevents a type of immune cell in the lung from becoming hyperactivated by allergens. The study, to be published March 26 in the Journal of Experimental Medicine (JEM), suggests that switching on Piezo1 could represent a new therapeutic approach to reducing lung inflammation and treating allergic asthma. Type 2 innate lymphoid cells (also known as ILC2s) are a type of immune cell that resides in the lungs, skin, and other tissues of the body. ILC2s in the lungs become activated in the presence of allergens and produce ...

JSCAI publishes special issue: Cardiac CT Angiography in Diagnosis, Treatment, and Prognosis of Cardiac Disease

2024-03-26

Cardiac computed tomography angiography (CCTA or CTA) has emerged as a first-line tool for diagnosing, treating, and evaluating the prognosis of various cardiac diseases. In this special issue of JSCAI, "The Role of Cardiac Computed Tomography Angiography in Diagnosis, Treatment, and Prognosis of Cardiac Disease", experts detail the broad spectrum of uses of this imaging modality, acknowledging the role of this test in current clinical and procedural practice, including: Risk stratification Ruling out coronary artery disease in patients with chest pain Assessing ...

Just ask: patients in the ER are willing to get a flu shot

2024-03-26

Simply asking patients to get the flu vaccine, and combining it with helpful video and print messages, is enough to persuade many who visit emergency departments to roll up their sleeves, according to a new study led by UC San Francisco. Researchers found a 32% vaccine uptake in patients who were asked if they’d be interested in getting the flu shot and told their health providers would be informed. They saw a 41% uptake for those who were asked about receiving a flu shot and received a pamphlet, watched ...

Collaborative University of Cincinnati Cancer Center team opens Phase 2 brain tumor trial

2024-03-26

A multidisciplinary team of University of Cincinnati Cancer Center researchers have opened a Phase 2 clinical trial to test a new combination treatment for glioblastomas (GBM), the most deadly form of brain tumors. The team, led by UC’s Pankaj Desai, PhD, and Trisha Wise-Draper, MD, PhD, has been awarded a Catalyst Research Award from the Dr. Ralph and Marian Falk Medical Research Trust to move the trial forward. Study background Difficult to diagnose at early stages, GBMs are aggressive brain tumors that become symptomatic once the tumor is substantial. Current treatments include ...

Silicon spikes take out 96% of virus particles

2024-03-26

An international research team led by RMIT University has designed and manufactured a virus-killing surface that could help control disease spread in hospitals, labs and other high-risk environments. The surface made of silicon is covered in tiny nanospikes that skewer viruses on contact. Lab tests with the hPIV-3 virus – which causes bronchitis, pneumonia and croup – showed 96% of the viruses were either ripped apart or damaged to the point where they could no longer replicate to cause infection. These impressive results, featured on the cover of top nanoscience journal ACS Nano, show the material’s promise ...
