One‐Step Induction of Oogonia‐Like and Pro‐Spermatogonia‐Like Cells From Porcine Pluripotent Stem Cells

Advanced Science, EarlyView.
This study established a one‐step method inducing pro‐spermatogonia‐like (activating SOX17) and oogonia‐like (activating SOX17/TFAP2C) cells from porcine pgEpiSCs with a NANOS3‐tdTomato reporter. EGF activates the core PGC program and supports survival; BMP4 further induces NANOS3 and DDX4 expression; IWR1 enhances PGCLC efficiency by suppressing ...

Aged ZnO Nanoparticles Promote Breast Cancer Lung Metastasis by Remodeling the Pulmonary Microenvironment Through the CXCL10/Wnt/β‐Catenin Axis

Advanced Science, EarlyView.
In summary, pulmonary exposure to ZnO NPs, particularly aged NPs, promotes breast cancer metastasis by remodelling the lung tumour microenvironment. Aged ZnO NPs enrich M2‐macrophages, MDSCs and activated CAFs to form an immunosuppressive metastatic niche. CXCL10 from these cells drives metastasis via Wnt/β‐catenin activation.

Unlocking the Full Potential of Jumping Condensation on Microstructured Surfaces

Advanced Science, EarlyView.
Microcone arrays exhibit a spacing‐dependent transition between jumping and non‐jumping condensation. Dense microstructures favor full Cassie droplets, which depart cleanly, while wider spacing favors partial Cassie droplets that retain a localized wet region initiating new nucleation. These findings establish a link between microdroplet morphology and

Mitochondrial Quality Control in Degenerative Musculoskeletal Diseases: Signaling Networks and Therapeutic Landscapes

Advanced Science, EarlyView.
Mitochondrial quality control (MQC) collapse redefines osteoarthritis, intervertebral disc degeneration, and osteoporosis as disorders of organelle dysfunction. Damaged mitochondria leak mtDNA and metabolites, driving cGAS‐STING inflammation, epigenetic reprogramming, and metabolic memory.

Extreme Weather Events and Consumer Food Responses

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study investigates consumer food responses to Hurricanes Helene and Milton, which affected a swath of the Southeastern U.S. in 2024. Using representative consumer survey data from six affected states, we analyze 10 distinct food responses classified into ex ante and ex post responses, and examine their associations with food insufficiency

Multivariate measure of niche overlap using canonical correspondence analysis

Ecoscience, 1997
A measure of multidimensional niche overlap based on species scores from canonical correspondence analysis is presented. This measure, N, is the amount of overlap using species scores as approximate weighted averages with respect to multidimensional ...

Anthropogenic fire patterns affect niche breadth and niche overlap in sympatric songbird species [PDF]

Science of the Total Environment, 2022
The severity of wildfires increases globally, and return intervals decrease. Fires can benefit biodiversity, as post-burn early successional stages provide diverse habitats and niches for many species.

Distance and cosine measures of niche overlap

Social Networks, 2001
Abstract Niche overlap is increasingly used as a way of measuring the intensity of interorganizational competition. This paper examines and compares various distance and cosine measures of niche overlap. The analysis in this paper shows that Euclidean distance applied to the raw data as well as to transformed data is not an appropriate measure of ...

On the Measurement of Niche Breadth and Overlap

Ecology, 1971
Measures of niche breadth and overlap that depend on the distribution of individual among resource states (ecological categories) should be independent of the relative abundance of the species and of the number of resource states considered. Such measures should also take into account the degree of distinctness of the resource states from the point of ...

Measures of Niche Overlap

Ecology, 1980
This paper examines the mathematical bases of three commonly used measures of niche overlap along a single resource dimension: curve averaging, asymmetrical α and symmetrical α. Also, we examine the common methods (product α, summation α) for calculating overlap along two or more resource dimensions.
