High‐elevation adaptation and gestational hypoxia jointly shape vascular development in a rodent placenta

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated how environmental hypoxia and genetic adaptation to high altitudes jointly impact the development of the placental exchange surface in ways that might protect fetal growth potential. We used wild‐derived, lab‐born North American deer mice (Peromyscus maniculatus) from low‐elevation and high‐elevation environments (

Tips for Studies with Quantitative Morphology (Morphometry and Stereology)

, 2017
The quantitative morphology contributes to making the studies less subjective and reproducible. Quantitative results are analyzed with statistics and should be based on a well-defined sample.

Cell Surface Markers Identify Astrocyte Subpopulations in the Adult Hippocampus With a Heterogeneous Response to Aging

Glia, Volume 74, Issue 11, November 2026.
ATP1B2 and GLAST identify two astrocyte subpopulations in the hippocampus with distinct molecular signatures. Transcriptomic shifts during aging differ between both subpopulations. Aged ATP1B2+ astrocytes rewire their metabolism while double‐positive aged astrocytes display a reduced synaptogenic capability.

Design-based stereology to quantify structural properties of artificial and natural snow using thin sections [PDF]

, 2012
The quantification of the structural properties of snow is traditionally based on model-based stereology. Model-based stereology requires assumptions about the shape of the investigated structure. Here, we show how the density, specific surface area, and

Brain Volume Estimation Enhancement by Morphological Image Processing Tools

Journal of Biomedical Physics and Engineering, 2017
Background: Volume estimation of brain is important for many neurological applications. It is necessary in measuring brain growth and changes in brain in normal/ abnormal patients. Thus, accurate brain volume measurement is very important.

Evaluation of Drillability of the Mahu Conglomerate Formation in Xinjiang, China

Energy Science &Engineering, Volume 14, Issue 9, Page 4095-4112, September 2026.
This graphical abstract illustrates the workflow for developing an optimized prediction model using measurement while drilling (MWD) data. A total of 90 MWD cases are divided into a training set (80%) and a test set (20%). Four logging‐while‐drilling parameters—compensation density, acoustic travel time, resistivity, and neutron porosity—are selected ...

Biochemical, morphological and molecular assessments of n butanol fraction of Phoenix dactylifera L. following exposure to inorganic mercury on the liver of Wistar rats

Laboratory Animal Research
Background Mercury chloride (HgCl2) damages tissues it comes in contact with in sufficient concentration. This study evaluated the protective effects of n-butanol fraction of Phoenix dactylifera (BFPD) on mercury-triggered liver toxicity in Wistar rats ...

Comparison of methods for quantifying primordial follicles in the mouse ovary

Journal of Ovarian Research, 2020
Background Accurate evaluation of primordial follicle numbers in mouse ovaries is an essential endpoint for studies investigating how endogenous and exogenous insults, such as maternal aging and chemotherapy, impact the ovarian reserve. In this study, we

Visibility and Intersection Density for Boolean Models in Hyperbolic Space

Mathematische Nachrichten, Volume 299, Issue 9, Page 2542-2565, September 2026.
ABSTRACT For Poisson particle processes in hyperbolic space we introduce and study concepts analogous to the intersection density and the mean visible volume, which were originally considered in the analysis of Boolean models in Euclidean space. In particular, we determine a necessary and sufficient condition for the finiteness of the mean visible ...
