Chromophobe renal cell carcinoma with nodal involvement: A rare case report highlighting unusual molecular features

Sam Kwon; Tali Newman; Fiona Wardrop et al.

Urology Case Reports, Vol. 67 · 2026 · English · DOAJ Scopus

Chromophobe renal cell carcinoma (ChRCC) is a renal malignancy typically associated with indolent behavior, with nodal involvement being rare. We report a 78-year-old African American male with incidentally discovered node-positive (pN+) ChRCC with sarcomatoid differentiation who developed spinal…

Improved choleretic effect of Benachio-F®-based formula enriched with fennel extracts

Hye Jin Cho; Jun Su Im; Yong Sam Kwon et al.

Journal of Animal Reproduction and Biotechnology, Vol. 37 No. 1 · 2022 · Korean · DOAJ

Functional dyspepsia (FD) is a gastrointestinal disorder with diverse symptoms but no structural or organic manifestations. Benachio-F® (herein named ‘BF-1’) is an over-the-counter liquid digestive formulated with multiple herbal extracts, which has been reported to improve symptoms of FD. A total…

Natural eggshell membrane supplementation for chronic lameness in warmblood horses: a 12-week prospective before–after study

Young-Sam Kwon; Hyohoon Jeong; Jongkyu Kim et al.

Frontiers in Veterinary Science, Vol. 13 · 2026 · English · DOAJ Scopus

IntroductionOsteoarthritis is a leading cause of equine lameness, yet pragmatic evidence for nutraceuticals in horses remains limited.MethodsWe prospectively evaluated 12 weeks of daily natural eggshell membrane (NEM; 12 mg/kg, orally) supplementation in Warmblood horses with chronic lameness using…

Passive Sensing in the Prediction of Suicidal Thoughts and Behaviors: Protocol for a Systematic Review

Tanita Winkler; Rebekka Büscher; Mark Erik Larsen et al.

JMIR Research Protocols, Vol. 11 No. 11 · 2022 · English · DOAJ Scopus

BackgroundSuicide is a severe public health problem, resulting in a high number of attempts and deaths each year. Early detection of suicidal thoughts and behaviors (STBs) is key to preventing attempts. We discuss passive sensing of digital and behavioral markers to enhance the detection and…
