Imaging-based algorithmic approach to gallbladder wall thickening

World Journal of Gastroenterology, 2020
Gallbladder (GB) wall thickening is a frequent finding caused by a spectrum of conditions. It is observed in many extracholecystic as well as intrinsic GB conditions. GB wall thickening can either be diffuse or focal.

Ultrastructure and probable botanical affinity of the enigmatic sporomorph froelichsporites traversei from the norian (Late triassic) of North America [PDF]

, 2018
Premise of research. Froelichsporites traversei is a prominent palynomorph in the Upper Triassic of North America that always occurs in tetrahedral permanent tetrads. It is an important regional biostratigraphic marker in the Norian of North America, and

Marked Ericales diversity in late Oligocene–Early Miocene palynofloras from northern Thailand suggests stratified mountain forests

Journal of Systematics and Evolution, Volume 63, Issue 6, Page 1458-1480, November 2025.
Ericalean pollen was recovered from the Ban Pa Kha Subbasin, Li Basin, northern Thailand. Based on the ecological preferences of their modern analogs, the assemblage of dispersed ericalean pollen likely derives from more than one vegetation type and possibly from different vertical zones of mountainous areas.

A Genome‐Wide Association Screen for Genes Affecting Leaf Trichome Development and Epidermal Metal Accumulation in Arabidopsis

Plant, Cell &Environment, Volume 48, Issue 5, Page 3708-3734, May 2025.
ABSTRACT To identify novel genes engaged in plant epidermal development, we characterized the phenotypic variability of rosette leaf epidermis of 310 sequenced Arabidopsis thaliana accessions, focusing on trichome shape and distribution, compositional characteristics of the trichome cell wall, and histologically detectable metal ion distribution.

Vessel Wall Thickening and Enhancement in High-Resolution Intracranial Vessel Wall Imaging: A Predictor of Future Ischemic Events in Moyamoya Disease

American Journal of Neuroradiology, 2020
Twenty-nine patients with Moyamoya disease were enrolled in this study. The median age at symptom onset was 12 years. A total of 166 steno-occlusive lesions were detected by high-resolution intracranial vessel wall imaging. Eleven lesions with concentric

OsALKBH9‐mediated m6A demethylation regulates tapetal PCD and pollen exine accumulation in rice

Plant Biotechnology Journal, Volume 22, Issue 9, Page 2410-2423, September 2024.
Summary The N6‐methyladenosine (m6A) mRNA modification is crucial for plant development and stress responses. In rice, the male sterility resulting from the deficiency of OsFIP37, a core component of m6A methyltransferase complex, emphasizes the significant role of m6A in male fertility. m6A is reversible and can be removed by m6A demethylases. However,

Roughness-dependent tribology effects on discontinuous shear thickening [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Shear thickening is a ubiquitous rheological phenomenon whereby dense suspensions of particles in a fluid exhibit a viscosity increase at high shear, which can turn into a viscosity divergence [discontinuous shear thickening (DST)]. Although
