Modified cytoskeletal and extracellular matrix composition in the canine testis after long‐acting gonadotropin‐releasing hormone agonist deslorelin treatment

open access: yesAndrology, EarlyView.
Abstract Background Long‐acting gonadotropin‐releasing hormone (GnRH) agonists are commonly used for fertility control in male dogs. Their effect on testicular histomorphology has not been clarified. Objectives To elucidate the mechanisms underlying androgen withdrawal in response to long‐acting GnRH agonist deslorelin 4.7 mg treatment on testicular ...

Host parameters and mode of infection influence outcome in SARS-CoV-2-infected hamsters

open access: yesiScience, 2021
Summary: The golden hamster model of SARS-CoV-2 infection recapitulates key characteristics of COVID-19. In this work we examined the influence of the route of exposure, sex, and age on SARS-CoV-2 pathogenesis in hamsters. We report that delivery of SARS-

The acrosomal region and the acrosome reaction in sperm of the golden hamster.

open access: yesBiology of Reproduction, 1970
Electron microscopic observations of golden hamster spermatozoa and spermatids indicate that the perforatorium is equivalent to the subacrosomal space and contents described by others in a variety of mammalian sperm.

The fast‐dissociating D2 antagonist antipsychotic JNJ‐37822681 is a neuronal Kv7 channel opener: Potential repurposing for epilepsy treatment

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Pharmacological activation of neuronal M‐current mediated by Kv7 (Kv7.2–5) potassium channels is a validated mechanism for epilepsy treatment. However, since the market withdrawal of the prototype Kv7 activator retigabine, no Kv7 activator is clinically available for this condition.

Reduced-Fat Response of Lactobacillus casei subsp. casei SY13 on a Time and Dose-Dependent Model

open access: yesFrontiers in Microbiology, 2018
A reduced-fat effect of probiotics was primarily derived functionally rather than structurally, and we investigated the ultra-structural aspect of the gut mucosa in Syrian golden hamsters with high-fat diet by feeding with Lactobacillus casei subsp ...

Ca-mediated activation of a K current at fertilization of golden hamster eggs.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1982
Golden hamster eggs respond to fertilization with recurring hyperpolarizations [Miyazaki, S. & Igusa, Y. (1981) Nature (London) 290, 703-705]. We analyzed the ionic mechanism of the fertilization potential and examined whether the fertilization potential

Stress alters hypothalamic gene expression in adolescent male Golden hamsters

open access: yesJournal of Neuroendocrinology, EarlyView.
Abstract In Golden hamsters (Mesocricetus auratus), a two‐week exposure to chronic social stress in adolescence causes acceleration of agonistic behavior, enhanced adult aggression, impaired waiting impulsivity, and higher food intake, body fat, and long‐term increased body weight.

Pineal melatonin is a circadian time-giver for leptin rhythm in Syrian hamsters

open access: yesFrontiers in Neuroscience, 2015
Nocturnal secretion of melatonin from the pineal gland may affect central and peripheral timing, in addition to its well-known involvement in the control of seasonal physiology.

Measuring Personality in Wild Small Mammals: A Review of Methods and Proposal for a Standardised Approach

open access: yesMammal Review, EarlyView.
We provide a systematic review of methodologies used to study personality in small mammals. We propose adopting ‘Standardised Experimental Design’ and ‘Behavioural Measurements’ to effectively compare results across studies and foster progress in this field.
