An AI model successfully automates lymph node segmentation and extranodal extension classification from pretreatment CT scans in HPV-associated oropharyngeal carcinoma. Predicted extranodal extension is independently associated with worse oncologic outcomes, highlighting the potential for improved treatment planning.
Researchers used AI to detect localized versus advanced cancer stages in oropharyngeal squamous cell carcinoma patients. The study suggests improved patient care and clinical decision-making through AI-assisted health record extraction.
The HALP score, a novel immune-nutritional marker, has been linked to prognostic ability in different cancer types. It integrates indicators of immune status and nutritional status, showing promise as a cost-effective biomarker.
Scientists have discovered evidence that yunnanozoans are the oldest known stem vertebrates, with cellular cartilages in the pharynx similar to those found in modern vertebrates. The team's findings support the evolutionary placement of yunnanozoans at the very basal part of the vertebrate tree of life.
Researchers found that the oral plug, a structure in fin whales, blocks the pharynx and prevents water from entering during lunge feeding. This allows the whale to swallow prey while keeping the respiratory tract protected.
Researchers discovered that lunge-feeding whales have an 'oral plug' in their mouths, which seals off the upper airways during feeding. This mechanism prevents water from entering their lungs and allows them to gulp down large amounts of krill without drowning.
Researchers discovered new species and genera related to the genus Ctenopharyngodon, revealing that grass carp originated during the Oligocene in western China. The fossil record shows a transformation from carnivorous ancestors to herbivores as the environment changed.
Researchers discovered that individual taste neurons in fruit flies can detect compounds from multiple taste categories, influencing feeding decisions. The team found that single-taste neurons are capable of responding to more than one tastant category, and that a single tastant category can activate multiple classes of taste neurons.
A new study shows that snowflake morays can grab and swallow prey on land thanks to an extra set of jaws in their throats, allowing them to utilize different environments for food resources. This unique feeding mechanism enables at least one species of moray to feed on land without relying on water.
Researchers found COVID-19 positive results in sputum and feces samples of patients with negative pharyngeal swabs, suggesting additional body site sampling may be needed. The study highlights the need for further investigation into patient safety and infectiousness after discharge.
A UC Riverside-led research team found that fruit fly taste neurons can detect different categories of aversive chemicals and convey this information to the brain, where it controls food intake. The study's findings have implications for understanding feeding behavior in insects and could lead to strategies for controlling insect pests...
Direct visualization of air flow patterns in the human upper airway has been achieved using in-vitro models with realistic anatomical structures. The study reveals that airflow is a laminar flow with vortices, rather than turbulent, under normal inspiration.
Researchers at UC Riverside have found a way to access and manipulate taste neurons in the pharynx of common fruit flies, which could help control the spread of mosquito-related illnesses and reduce agricultural losses. This genetic approach offers a new framework for understanding the complexities of insect feeding behaviors.
A study published in Gastrointestinal Endoscopy found ESD to be a safe and effective treatment for superficial pharyngeal cancer, achieving an en bloc resection rate of 100% and complete resection rate of 79.5%. The procedure showed minimal side effects, with a three-year overall survival rate of 97.7%.
The acorn worm's genome has revealed the origin of the human pharynx, showing how gill slits evolved into the jaw and throat. The study found that humans and other terrestrial vertebrates retain vestigial gills in embryos, a trait shared with marine animals.
A team of scientists identified a key regulator called FoxA that drives pharynx regeneration in planarian worms. The study reveals how stem cells sense loss of a structure and rebuild it, shedding light on the mechanisms behind regeneration in these animals.
Researchers at UCSB have identified a way to change one cell type into another using transcription factor ELT-7, which was previously thought to be exclusive to early embryonic cells. The discovery opens up new possibilities for regenerative medicine and could potentially allow for the creation of entire organs from scratch.
Researchers at USC have identified two molecular signaling pathways that control the formation of head and face structures, shedding light on certain birth defects. The study used time-lapse photography to study organ development at the single-cell level in zebrafish embryos, providing insights into human health and disease.
Researchers compared pharyngeal nervous systems of nematode Caenorhabditis elegans and predator/omnivore Pristionchus pacificus, finding large differences in neuronal connections. These differences reflect the fundamental differences in feeding behaviors between the two species.
Researchers investigated chronic acid-reflux esophagitis in a rat model, discovering epithelial thickening and inflammatory cell infiltration in the middle to lower esophagus. Ecabet sodium inhibited these changes, suggesting its potential role in preventing reflux esophagitis.
Researchers discovered moray eels use a second set of jaws to grab food, then bring it back to the esophagus for swallowing. This unusual feeding behavior is unlike most fish, which rely on suction.
Research found that fluid displacement from the legs to the neck can narrow soft tissue around the throat and increase airflow resistance in healthy individuals, predisposing them to obstructive sleep apnea. The study involved measuring leg fluid volume, neck circumference, and airflow resistance in 11 non-obese subjects, with results ...
Researchers discovered a biochemical reaction controlling how the worm feeds, which may help understand feeding disorders. The study suggests that inappropriate behavioral responses to starvation signals could be the cause of feeding disorders in mammals.
Researchers have developed a C. elegans-based screening tool to identify novel protein regulators of a potassium channel involved in the heartbeat, which may help prevent arrhythmias and sudden death associated with blockage of the HERG gene.
Researchers found that halting COPD treatment with inhaled corticosteroids increases exacerbation risk and worsens quality of life. Men are more prone to pharyngeal collapse due to longer airways, which may contribute to their higher obstructive sleep apnea risk. Additionally, patients with OSA showed reduced brain gray matter volume, ...
