Age‐associated immune dysregulation links to disease severity in macrolide‐resistant Mycoplasma pneumoniae pneumonia: Insights from a comparative juvenile–adult mouse model

Animal Models and Experimental Medicine, EarlyView.
Macrolide‐resistant Mycoplasma pneumoniae (MRMP) infected both juvenile and adult mice, with results compared to normal juvenile mice. The findings revealed comparable bacterial loads between juvenile and adult mice, yet juvenile mice exhibited more severe lung damage and elevated levels of inflammatory cytokines.

Correlations between environmental salinity levels, blood biochemistry parameters, and steroid hormones in wild juvenile American alligators (Alligator mississippiensis)

Scientific Reports, 2021
American alligators (Alligator mississippiensis) inhabit freshwater wetlands that are vulnerable to salinization caused by anthropogenic alterations to freshwater flow, in addition to storm surges, sea level rise, and droughts.

Evaluation of therapeutic effects of D‐limonene following orchiopexy in the rat model of cryptorchidism

Animal Models and Experimental Medicine, EarlyView.
D‐limonene supplementation enhances testicular recovery following orchiopexy in a rat model of bilateral cryptorchidism. Treatment with D‐limonene reduces oxidative stress (↓MDA, ↑SOD, ↑GPx, ↑TAC), downregulates pro‐apoptotic proteins (↓TNF‐α, ↓BAX, ↓Caspase‐3), and upregulates anti‐apoptotic Bcl‐2 expression.

Adaptive host responses to infection can resemble parasitic manipulation

Ecology and Evolution, 2023
Using a dynamic optimisation model for juvenile fish in stochastic food environments, we investigate optimal hormonal regulation, energy allocation and foraging behaviour of a growing host infected by a parasite that only incurs an energetic cost.

Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

The Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...

Effects of Methyl Farnesoate on the Growth and Antioxidant Capacity of Neocaridina denticulata

Antioxidants
Sesquiterpenoid hormones are widely present in arthropods and play crucial roles in growth, molting and reproduction. Methyl farnesoate (MF) functions similarly to juvenile hormone (JH) in crustaceans, playing a broad regulatory role in their growth and ...

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

The Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Endogenous Recovery of Hippocampal Function Following Global Cerebral Ischemia in Juvenile Female Mice Is Influenced by Neuroinflammation and Circulating Sex Hormones

Neural Plasticity
Cardiac arrest (CA)-induced global cerebral ischemia (GCI) in childhood often results in learning and memory deficits. We previously demonstrated in a murine CA and cardiopulmonary resuscitation (CA/CPR) mouse model that a cellular mechanism of learning ...

Characterization of the juvenile hormone pathway in the viviparous cockroach, Diploptera punctata.

PLoS ONE, 2015
Juvenile hormones (JHs) are key regulators of insect development and reproduction. The JH biosynthetic pathway is known to involve 13 discrete enzymatic steps.

Pelvic morphology and body size in relation to the preauricular sulcus: Evidence from medieval to modern Iberia

The Anatomical Record, EarlyView.
Abstract The preauricular sulcus has long been debated as a pelvic feature variably attributed to obstetric stress, ligamentous traction, and broader biomechanical processes. To clarify its determinants, we analyzed 409 adult individuals from three archeological and one early modern skeletal collection from the Iberian Peninsula, integrating graded ...
