Researchers report on the largest cohort of patients tested using plasma mcfDNA sequencing for pathogen detection

Researchers identified a wide variety of pathogenic organisms using plasma mcfDNA sequencing.

Intranasal mRNA-lipid nanoparticle vaccines elicit significant protection against SARS-CoV-2 in hamsters

Researchers from the United States evaluated the efficacy and immunogenicity of an intranasal messenger ribonucleic acid (mRNA)-lipid nanoparticle (LNP) vaccine against SARS-CoV-2 using a hamster model.

Study uncovers a strong link between gut bacteria and development of Parkinson’s disease

Parkinson's disease may start in the gut and spread to the brain, a new study from the University of Surrey suggests.

Study directly links gut leakage with retinopathy severity in people with Type 1 diabetes

The leading cause of blindness in American adults is diabetic retinopathy, progressive damage to blood vessels in the light-sensitive tissue at the back of the eye.

Researchers study bacterial co-infections and antibiotic use in COVID-19 patients

Researchers estimated the frequency of bacterial co-infections among hospitalized coronavirus disease 2019 (COVID-19) patients and of antibiotic prescriptions in the initial COVID-19 period for appraising the usage of antibiotic stewardship criteria.

Bacteria play specific roles in cancer

In a recent article published in the journal Immunity, the authors discussed the findings from a 2022 study by Galeano Niño et al., which reported that microbiota associated with tumors form micro-niches and play a role in epithelial and immune mediations of cancer.

Reshaping the gut microbiome could be a possible way to prevent or treat neurodegeneration

A growing pile of evidence indicates that the tens of trillions of microbes that normally live in our intestines - the so-called gut microbiome - have far-reaching effects on how our bodies function.

New research identifies natural compounds with pan-SARS-CoV-2 inhibitory activity

Scientists have recently conducted a cell-based high-content screening of over 300 natural compounds and identified three compounds with potent antiviral activities against SARS-CoV-2 and its variants.

Screening patients for hidden reservoirs of bacteria could supplement infection-control efforts in hospitals

Hospitals have strict hygiene and sanitation protocols to protect patients from bacteria that rarely sicken healthy people but can be deadly for vulnerable patients already hospitalized with serious illnesses.

Study on bacterial infection in older individuals

The older population is prone to microbial infections, which can lead to death. Hence, it is important to understand why this group is vulnerable to microbial infection, especially bacterial infection. A recent Scientific Reports study linked data from two sources to understand the determining factors for microbial infection in the older population in the UK.

Study reveals how inflammation alters the tumor microenvironment in acute myeloid leukemia

Severe inflammation weakens the body's ability to kill cancerous blood cells in people with acute myeloid leukemia (AML), a new study shows.

Newly discovered CRISPR immune system shuts down infected cells to thwart infection

In this interview, News Medical speaks to Assitant Professor Ryan Jackson about his latest work, published in tandem Nature papers, detailing the discovery of a new CRISPR immune system.

Injectable hydrogel suppresses infections and promotes healing around prosthetics

Total hip and knee replacements are challenging enough for patients. When an infection occurs in the aftermath, the results are often disastrous, requiring potent antibiotics and revisionary surgery.

10 Jan 2023

Researchers review bacteriophage treatment

Researchers presented an overview of bacteriophage treatment, including mechanisms, types, design and applications of bacteriophage therapy.

Vaccinating against toxin produced by E. coli may protect against malnutrition and stunting

Diarrhea is no longer the killer it was in the mid-20th century, when an estimated 4.5 million children under age 5 died of it every year.

Compounds derived from B.C. sea sponge can prevent COVID-19 infection in human cells

UBC researchers have identified three compounds that prevent COVID-19 infection in human cells, derived from natural sources including a B.C. sea sponge.

An updated framework for understanding the biology of the bacterial system

Nobody wants to be average. But for a long time, scientists have found it convenient to think of bacterial cells as just that: "average."

Vitamin D can help the immune system fight tuberculosis, study says

Most people probably associate tuberculosis with a leaky loft in 20th-century Paris. But as a matter of fact, tuberculosis is not ancient history.

6 Jan 2023

Study offers novel insights into the elongation dynamics of eukaryotic cells

Life depends on the precise functioning of several proteins synthesized in cells by ribosomes. This diverse set of proteins, known as a proteome, is maintained by the robust translation elongation of amino acid sequences taking place in the ribosomes.

Scientists pinpoint the routes taken by SARS-CoV-2 to enter and exit cells in our nasal cavity

Somebody just coughed on you. On a plane. At a dinner party. In a supermarket line. If only there were a "morning after" nasal spray that could knock out respiratory viruses' ability to colonize your nose and throat.
