Scientists create new way to detect COVID-19 proteins and antibodies

Scientists have created a new way to detect the proteins that make up the pandemic coronavirus, as well as antibodies against it. They designed protein-based biosensors that glow when mixed with components of the virus or specific COVID-19 antibodies.

Inflammation may contribute to the persistence of C. diff infection, shows study

A new study from North Carolina State University shows that the inflammation caused by Clostridioides difficile (C. diff) infection gives the pathogen a two-fold advantage: by both creating an inhospitable environment for competing bacteria and providing nutrients that enable C. diff to thrive.

Certain snakes evolve a unique genetic trick to avoid venomous snake-eating snakes

Certain snakes have evolved a unique genetic trick to avoid being eaten by venomous snakes, according to University of Queensland research.

New approach to tame botulinum toxin for drug delivery

While rare, botulism can cause paralysis and is potentially fatal. It is caused by nerve-damaging toxins produced by Clostridium botulinum -- the most potent toxins known.

CytoDel successfully delivers neuronal antibody in animal models of botulism

CytoDel, Inc., a privately-held corporation, today announces the publication of preclinical data on the Company's lead product, Cyto-111, in the peer-reviewed journal, Science Translational Medicine. The complete text of the article titled, "Neuronal Delivery of Antibodies has Therapeutic Effects in Animal Models of Botulism," can be found here.

New approach produces strong antidotal efficacy in treating lethal botulism in animals

Related to new research published in the January issue of Science Translational Medicine, Patrick McNutt, PhD, of the Wake Forest Institute for Regenerative Medicine, was part of the research team that demonstrated a new "Trojan horse" approach that produces strong antidotal efficacy in treating lethal botulism in mice, guinea pigs and rhesus macaque monkeys.

Researchers examine the role of Shiga toxin in the immune system

E. coli food poisoning is one of the worst food poisonings, causing bloody diarrhea and kidney damage. But all the carnage might be just an unintended side effect, researchers from UConn Health report in the 27 November issue of Science Immunology.

Non-toxic versions of botulism toxins can deliver therapeutic antibodies to treat botulism

Taking advantage of the chemical properties of botulism toxins, two teams of researchers have fashioned non-toxic versions of these compounds that can deliver therapeutic antibodies to treat botulism, a potentially fatal disease with few approved treatments.

Gut microbe may play a role in the development of breast cancers

A microbe found in the colon and commonly associated with the development of colitis and colon cancer also may play a role in the development of some breast cancers, according to new research from investigators with the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Institute for Cancer Immunotherapy.

Experts assess the impact of COVID-19 on pediatric patients with special needs

The impact of the COVID-19 pandemic on children with disabilities has not received much attention, perhaps because the disease disproportionately affects older individuals.

Certain aquatic insects can forewarn against possible outbreaks of diarrheal disease, shows study

Chironomids, a group of aquatic insects closely related to mosquitoes, act as natural reservoirs of disease-causing cholera bacteria and can forewarn against possible outbreaks of the diarrhoeal disease, a new study suggests

Researchers identify neurons that regulate nausea-like responses in mice

At some point, everyone experiences nausea. Whether it occurs after unwisely eating a week-old slice of pizza or as an accompaniment to a serious infection, that queasy, unsettling sensation centered around the stomach is a signal that something is amiss within the body and typically portends a bout of vomiting.

New model shows how bacteria behave in multiple scenarios with common spatial patterns

Bacteria is all around us - not just in bathrooms or kitchen counters, but also inside our bodies, including in tumors, where microbiota often flourish.

Toxin produced by E. coli bacteria also has nondiarrheal effects on the digestive tract

For people in wealthy countries, diarrhea is usually nothing more than an uncomfortable inconvenience for a few days. But for a poor child in a developing country, repeated bouts of diarrhea can lead to serious health consequences such as malnutrition, stunted growth and cognitive deficits.

Researchers pinpoint factors associated with uranium contamination in groundwater

Lurking in sediments and surrounding the precious groundwater beneath our feet is a dangerous toxin: uranium. Scientists have long known this and tested for it.

Researchers develop new method to evaluate vaccine safety

A research group at the University of Turku, Finland, has led the development of a new method to evaluate vaccine safety. The new method may significantly reduce the use of animal testing in the vaccine industry.

Chemotherapy combined with blinatumomab increases survival for patients with Ph-negative B-ALL

A study led by The University of Texas MD Anderson Cancer Center showed that first-line treatment with a regimen of chemotherapy combined with the monoclonal antibody blinatumomab resulted in increased survival and achieved a high rate of measurable residual disease (MRD) negativity for patients who were newly diagnosed with a high-risk form of acute lymphoblastic leukemia (ALL) known as Philadelphia chromosome-negative B-cell ALL (Ph-negative B-ALL).

Improved understanding of exposome-drug interactions could help prescribe effective drug doses

According to scientific estimations, humans are exposed to at least 10,000 to 100,000 environmental and exogenous compounds in an individual lifetime, which are mainly absorbed through our dietary.

New cyber-biological attack can trick biologists into generating dangerous toxins

An end-to-end cyber-biological attack, in which unwitting biologists may be tricked into generating dangerous toxins in their labs, has been discovered by Ben-Gurion University of the Negev cyber-researchers.
