Immunchemische Untersuchungen an Laubfrosch-Laich: Vergleichende Untersuchungen an Rana temporaria, Rana arvalis, Rana dalmatina und Rana latastei

open access: yesJournal of Zoological Systematics and Evolutionary Research, 2009
Zusammenfassung Laich von vier Braunfroscharten (Rana temporaria, R.arvalis, R. dalmatina, R.latastei) wurde auf blutgruppenaktive Substanzen untersucht. Anhand der vorgefundenen Reaktionsmuster lieβen sich die vier untersuchten Arten unterscheiden. R. dalmatina und R. latastei, zwei sehr ahnliche Arten, reagierten zwar unterschiedlich, zeigten aber

“Rana Esculenta” in Kincardineshire [PDF]

open access: yesNature, 1896
WHEN on a brief visit to Kincardineshire last month, I was surprised to find R. esculenta in considerable numbers at a few places which I visited. I found the frogs in pools beside the Bervie, and also in places several miles away. One of these was a small isolated bog. Mr.

Inverse sky islands: lowland river valleys drive microbial divergence while high elevations select for convergence in massive mountain ecosystems

open access: yesEcography, EarlyView.
Mountain ecosystems are often interpreted through the lens of the ‘sky island' model, where high‐elevation habitats function as isolated archipelagos. However, this model's applicability to massive, topographically complex mountain ranges where highlands are continuous and lowlands are fragmented remains untested.

Causal correlations between inflammatory proteins and heart failure: A two‐sample Mendelian randomization analysis

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1374-1385, April 2025.
Abstract Aims Inflammation plays a critical role in both the development and progression of heart failure (HF), which is a leading cause of morbidity and mortality worldwide. However, the causality between specific inflammation‐related proteins and HF risk remains unclear.

Quantum spin metal state on a decorated honeycomb lattice

open access: yes, 2010
We present a modification of exactly solvable spin-(1/2) Kitaev model on the decorated honeycomb lattice, with a ground state of "spin metal" type. The model is diagonalized in terms of Majorana fermions; the latter form a 2D gapless state with a Fermi ...

Peptide RL‐QN15 Regulates Functions of Epidermal Stem Cells to Accelerate Skin Wound Regeneration via the FZD8/β‐Catenin Axis

open access: yesExploration, EarlyView.
Amphibian‐derived peptide RL‐QN15 activates the Wnt/β‐catenin signaling pathway by interacting with the FZD8 membrane receptor, promoting epidermal stem cells proliferation, migration, stemness, and EMT processes, thus promoting skin wound healing.
