Risk factors for the appearance of minimal pathologic lesions on vocal folds in vocal professionals [PDF]

Vojnosanitetski Pregled, 2012
Background/Aim. An excessive use or misuse of voice by vocal professionals may result in symptoms such are husky voice, hoarse voice, total loss of voice, or even organic changes taking place on vocal folds - minimal pathological lesions - MAPLs.

Extraction of Key-Frames From Endoscopic Videos by Using Depth Information

IEEE Access, 2021
Early detection of colorectal cancer (CRC) can reduce the risk of death. Polyps are the precursor to such cancer. Analyzing the polyps from the most significant frames out of thousands of endoscopy frames is vital for diagnosing and understanding disease.

Functional Analysis of Ligand‐Gated Chloride Channels in a Cnidarian Sheds Light on the Evolution of Inhibitory Signaling

Advanced Science, EarlyView.
We uncover a large variety of putative inhibitory ligand‐gated ion channels (LGICs) in the phylum Cnidaria, the sister group to all bilaterian animals. Phylogenetic analysis suggests a complex evolutionary history of inhibitory LGICs with diverse neurotransmitter ligands.

Intestinal schistosomiasis with colonic polyps

Nigerian Journal of Medicine, 2022
Schistosomiasis is a parasitic infection which commonly affects the intestine. Colonic polyps associated with intestinal schistosomiasis are not commonly reported in young people. Our case report describes a 20-year-old man from North-Central Nigeria who

Study on detection rate of polyps and adenomas in artificial-intelligence-aided colonoscopy

Saudi Journal of Gastroenterology, 2019
Background/Aim: To study the impact of computer-aided detection (CADe) system on the detection rate of polyps and adenomas in colonoscopy. Materials and Methods: A total of 1026 patients were prospectively randomly scheduled for colonoscopy with (the ...

Stem cells of Hydra magnipapillata can differentiate into somatic cells and germ line cells [PDF]

, 1987
We investigated whether all stem cells of Hydra can differentiate both somatic cells and gametes or if a separate germ line exists in these phylogenetically old organisms.

Context‐Dependent Role of GDF15: GDF15+ Tumor‐Associated Macrophages Suppress OSCC Progression by Enhancing Phagocytosis

Advanced Science, EarlyView.
This study identifies GDF15+ TAMs as a cell subset mediating tumor regression after immunotherapy. Macrophage‐intrinsic GDF15 enhances phagocytosis and antigen cross‐presentation to CD8+ T cells through the NF‐κB signaling pathway, thereby inhibiting tumor progression.

Fluorescence lifetime spectroscopy of tissue autofluorescence in normal and diseased colon measured ex vivo using a fiber-optic probe

, 2013
We present an ex vivo study of temporally and spectrally resolved autofluorescence in a total of 47 endoscopic excision biopsy/resection specimens from colon, using pulsed excitation laser sources operating at wavelengths of 375 nm and 435 nm.

Humanized and Charge‐Optimized CSPG4‐Specific CAR‐T Cells show Enhanced Efficacy against Head and Neck Squamous Cell Carcinoma

Advanced Science, EarlyView.
CSPG4 is identified as a high‐value, stemness‐associated target in HPV‐negative HNSCC. By implementing rational biophysical engineering, a humanized and charge‐optimized CAR is developed to overcome tonic signaling‐induced exhaustion. This strategy induces a profound transcriptomic shift toward a rejuvenated, stem‐like memory state, significantly ...

A Soft Matrix Microenvironment Promotes Laterally Spreading Tumors via Oxidative Phosphorylation‐Dependent Cell Adhesion

Advanced Science, EarlyView.
Laterally spreading tumors (LSTs) are precancerous colorectal lesions characterized by a flat morphology. This study reveals a mechanochemical pathway through which a soft matrix microenvironment diminishes spatial constraints in intestinal adenomas. This process promotes deficiencies in tight junction proteins, mediated by the mechanoreceptor ADORA2B ...
