Virulence Factors of Helicobacter pylori Responsible for Gastric Diseases in Mongolian Gerbil

Journal of Experimental Medicine, 2000
Helicobacter pylori infection induces various gastroduodenal diseases. We examined the role of two genes, vacA and cagE, in the gastric pathogenesis induced by H. pylori using a long-term (62 wk) animal model.

Adaptation to harshness is fundamentally different from the adaptive stress response: Results from a 20‐year‐long case study in African striped mice

Journal of Zoology, EarlyView.
Animals in harsh environments rely on specialised adaptations. Two decades of field research on African striped mice (Rhabdomys pumilio) in the Succulent Karoo semi‐desert reveal a distinct ‘harshness response’—marked by reduced metabolism and glucocorticoid levels—that differs fundamentally from the classic stress response.

Anatolian ground squirrel (Spermophilus xanthoprymnus) retina: Comparative expression of synaptophysin, NeuN, calbindin‐D28k, parvalbumin, glial fibrillary acidic protein, and Iba‐1 during pre‐hibernation and hibernation

The Anatomical Record, Volume 309, Issue 2, Page 451-470, February 2026.
Abstract Hibernation induces significant molecular and cellular adaptations in the retina to maintain function under reduced metabolic conditions. This study aimed to investigate the expression of neuronal, synaptic, and glial markers in the retina of Spermophilus xanthoprymnus during pre‐hibernation and hibernation periods using immunohistochemical ...

Giardia Cyst Wall Protein 1 Is a Lectin That Binds to Curled Fibrils of the GalNAc Homopolymer [PDF]

, 2010
The infectious and diagnostic stage of Giardia lamblia (also known as G. intestinalis or G. duodenalis) is the cyst. The Giardia cyst wall contains fibrils of a unique β-1,3-linked N-acetylgalactosamine (GalNAc) homopolymer and at least three cyst wall ...

Distribution of Voltage‐Gated Sodium Channels and Scaffolding Proteins on Vestibular Calyx Ending Delineates the Axon Initial Segment

Journal of Comparative Neurology, Volume 534, Issue 2, February 2026.
Various sodium channel isoforms and their scaffolding proteins are found in four different microdomains in vestibular calyx‐bearing afferents. These microdomains serve different purposes, analogous to the heminode, axon initial segment, and synaptic domains of other types of sensory afferents.

Functional anatomy of the middle and inner ears of the red fox, in comparison to domestic dogs and cats

, 2020
Anatomical middle and inner ear parameters are often used to predict hearing sensitivities of mammalian species. Given that ear morphology is substantially affected both by phylogeny and body size, it is interesting to consider whether the relatively ...
