The unusual microtubule polarity in teleost retinal pigment epithelial cells. [PDF]

open access: yes, 1988
In cells of the teleost retinal pigment epithelium (RPE), melanin granules disperse into the RPE cells long apical projections in response to light onset, and aggregate toward the base of the RPE cell in response to dark onset.

Welfare and Physiological Consequences of Non‐Lethal Blood Sampling From the Caudal Vasculature of Atlantic Salmon (Salmo salar L.)

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT The objective of this study was to evaluate welfare and health effects following single and repeated non‐lethal blood sampling from the caudal vasculature of Atlantic salmon. Two experiments were conducted at three different temperatures: a 6‐week freshwater experiment with fish weighing 50–100 g, undergoing up to four blood withdrawals, and a

Ultrastructure of the dermal chromatophores in the Fringe-toed lizard, Acanthodactylus orientalis

open access: yesZoologia (Curitiba), 2017
Histology and electron microscopic studies of the dorsal skin of the Fringe-toed lizard, Acanthodactylus orientalis Angel, 1936, showed three types of dermal chromatophores: xanthophores, iridophores and melanophores. These pigment cells were observed in

Widow rockfish: Proceedings of a workshop, Tiburon, California, December 11-12, 1980 [PDF]

open access: yes, 1987
This workshop was organized because of the increase between 1978 and 1980 in coastwide landings of widow rockfish, from less than 1,000 mt to more than 20,000 mt, and because of scientists' concern with the lack of knowledge both of the fishery and ...

Collective transport of weakly interacting molecular motors with Langmuir kinetics

open access: yes, 2015
Filament based intracellular transport involves the collective action of molecular motor proteins. Experimental evidences suggest that microtubule (MT) filament bound motor proteins such as {\it kinesins} weakly interact among themselves during transport

Vimentin Intermediate Filaments: A Paradigm Shift From Static Structure to Dynamic Cytoplasmic Network

open access: yesBioEssays, Volume 48, Issue 3, March 2026.
Vimentin intermediate filaments form a dynamic, motile network that interacts with microfilaments and microtubules. We propose a hybrid transport model to explain vimentin filament dynamics through cytoskeletal crosstalk and organelle‐associated transport.

RARβ2 is required for vertebrate somitogenesis [PDF]

open access: yes, 2017
During vertebrate somitogenesis, retinoic acid is known to establish the position of the determination wavefront, controlling where new somites are permitted to form along the anteroposterior body axis.

Hypothyroidism as Prognostic Factor in Cutaneous Melanoma: A 1553‐Patient Single‐Center Study

open access: yesCancer Medicine, Volume 15, Issue 3, March 2026.
ABSTRACT Background Cutaneous melanoma is a rising global health concern and identifying modifiable or associated risk factors remains essential for improving prognostic stratification. Hypothyroidism, affecting approximately 5.1% of the general population in Germany, has been associated with various malignancies. This study investigates the prevalence
