Spexin in the European sea bass, Dicentrarchus labrax: Characterization, brain distribution, and interaction with Gnrh and Gnih neurons

Journal of Comparative Neurology, Volume 531, Issue 2, Page 314-335, February 2023., 2023
The main objective of this work was to obtain detailed information on the distribution and localization of the spexin (Spx) system in the sea bass brain. To this purpose, we first identified and characterized the spx1 gene and analyzed its expression in the central nervous system (CNS) of the European sea bass by using quantitative Real‐Time Polymerase

A novel pilot animal model for bone augmentation using osseous shell technique for preclinical in vivo studies

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1331-1340, December 2022., 2022
Abstract Objectives Bone grafting is commonly used to reconstruct skeletal defects in the craniofacial region. Several bone augmentation models have been developed to evaluate bone formation using novel bone substitute materials. The aim of this study was to evaluate a surgical animal model for establishing a three‐dimensional (3D) grafting environment

Functional evolution of the feeding system in rodents [PDF]

, 2012
The masticatory musculature of rodents has evolved to enable both gnawing at the incisors and chewing at the molars. In particular, the masseter muscle is highly specialised, having extended anteriorly to originate from the rostrum.

Characteristic of Individual Indicators of Endogenous Intoxication in the Experimental Asthma Dynamics and Their Correction by Thiotriasolin [PDF]

, 2016
The aim of this work was to find out the specifics of changes in endogenous intoxication, middle mass molecules (MMM) and erythrocyte intoxication index (EII) in the blood of animals for experimental asthma in different periods of its development and to ...

Not so presto? Outcomes of sluggish prestin in outer hair cells [PDF]

AIP Conf. Proc. 3062, 050002 (2024), 2020
Prestin (SLC26A5), a protein essential for the sensitivity of the mammalian ear, was so named from \emph{presto}. The assumption was that this membrane protein supports fast movement of outer hair cells (OHCs) that matches the mammalian hearing range, up to 20 kHz in general and beyond, depending on the species.

Gray and white matter astrocytes differ in basal metabolism but respond similarly to neuronal activity

Glia, Volume 71, Issue 2, Page 229-244, February 2023., 2023
Main Points Gray and white matter astrocytes have different basal NADH/NAD+ redox states and ATP levels. Metabolism of both cell populations responds similarly to neuronal activity. Glutamate induced ATP loss is prevented by increasing extracellular K+.

Effect of old age on the subpopulations of enteric glial cells in human descending colon

Glia, Volume 71, Issue 2, Page 305-316, February 2023., 2023
Main Points The number of Sox‐10 immunoreactive (IR) enteric glial cells (EGCs) were unaltered with age in both the myenteric and submucous plexus. The density of S100‐IR EGCs declined among the elderly in the circular muscle and within the myenteric plexus per ganglionic area.

D701N mutation in the PB2 protein contributes to the pathogenicity of H5N1 avian influenza viruses but not transmissibility in guinea pigs

Frontiers in Microbiology, 2014
H5N1 highly pathogenic avian influenza virus (HPAIV) of clade 2.3.2 has been circulating in waterfowl in Southern China since 2003. Our previous studies showed that certain H5N1 HPAIV isolates within clade 2.3.2 from Southern China had high pathogenicity

Lymphocyte populations and their relationship to cell-mediated immune responses in aflatoxin-treated guinea pigs [PDF]

, 1982
Effects of aflatoxin on cell-mediated immunity were investigated in guinea pigs. Dose dependent reductions in skin test responses were observed in guinea pigs which received at least 0.040 mg/kg/day aflatoxin B(,1) equivalents (B(,1) eq) for 3 weeks ...

Is microglial dystrophy a form of cellular senescence? An analysis of senescence markers in the aged human brain

Glia, Volume 71, Issue 2, Page 377-390, February 2023., 2023
Main Points Aging‐related morphological changes in microglia (dystrophy) do not correlate with expression of universal senescence markers. Microglial dystrophy coincides with an aging‐related increase in microglial ferritin expression. Abstract Aging can cause morphological transformation in human microglia indicative of cell senescence, termed ...
