Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Effect of age class on the survivorship and spatial movement patterns of headstarted Texas horned lizards soft‐released into an urban population

open access: yesThe Journal of Wildlife Management, EarlyView.
When compared to resident lizards of the corresponding age class, juvenile headstarted Texas horned lizards soft‐released into an urban population exhibited more favorable responses to short‐term translocation objectives (i.e., daily movement rates, home range sizes, and survival rates) than did conspecifics headstarted to the adult age class ...

ZFP36L1 Enhances Microglial Ferroptosis in Ischemic Stroke by Reducing FTO‐Mediated N6‐Methyladenosine Demethylation of ACSL1 mRNA

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Microglia play an important role in ischemic stroke (IS). However, the molecular regulatory mechanisms underlying microglial ferroptosis in IS remain incompletely understood. In this study, blood samples were collected from 20 IS patients and 15 healthy volunteers.

Asymmetrical Steps: Osteomorphological and Metric Patterns of Cattle Phalanges to Determine Anatomical Position

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT This study presents a reproducible framework for identifying the anatomical position of cattle phalanges, integrating both morphological and osteometric approaches for application to modern and zooarchaeological assemblages. The dataset comprises 1853 phalanges from 106 individuals with known and unknown phalangeal position representing ...

Radiographic Screening of Wild and Semi‐Wild Cape Ground Squirrels (Geosciurus inauris) for the Presence of Peri‐Apical Masses Associated With Elodont Incisor Teeth

open access: yesZoo Biology, EarlyView.
Peri‐apical masses were absent in both wild and semi‐wild Cape ground squirrels, despite dietary differences and minor incisor trauma. These findings suggest such lesions are rare outside captivity and not induced by low‐fiber diets alone, adding to the literature on environmental and dietary risk factors in elodont tooth pathology.

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions

open access: yesIntegrative Zoology, EarlyView.
Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.

Genome‐wide association and interaction analysis for proliferative retinopathy in adults with type 2 diabetes born during famine: The DOLCE study in Ukraine

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Proliferative diabetic retinopathy (PDR) is one of the leading causes of blindness in working‐age adults. We have previously shown that the risk of PDR is significantly elevated in individuals with intrauterine exposure to famine. However, the genetic mechanisms mediating this association remain unknown.

Pattern of Wnt ligand expression during chick eye development

open access: yesBrazilian Journal of Medical and Biological Research, 2007
The dorsoventral axis of the eye is determined prior to optic cup invagination. A variety of signaling pathways have been implicated in the maintenance of the optic dorsoventral axis, including, but not limited to, bone morphogenetic protein 4, Sonic ...

First Insights on Photoreceptor Organ Ultrastructure in Marine Chaetonotida (Gastrotricha): Species of Xenotrichula and Draculiciteria (Xenotrichulidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Marine gastrotrichs inhabit sediments with limited available light, yet evidence suggests that photoreceptor organs are present throughout the phylum Gastrotricha. Here, we confirm this proposition with ultrastructural descriptions of photoreceptive organs in two species of Xenotrichulidae (Order Chaetonotida) that lack pigmented ocelli ...
