Tracing the Development of Understanding Rate of Change: A Case Study of Changes in a Pre-Service Teacher's Pedagogical Content Knowledge

open access: yes, 2004
This investigation adopts an interpretive approach to study the development of understanding rate of change through a pre-service high school teacher's emerging pedagogical content knowledge over a two-year period of time. Shulman's (1986) definition of

Flash Assembloids: A Rapid Biofabrication of a Platform for Modeling Early Glioblastoma Invasion at the Glioblastoma–Brain Organoid Interfaces

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a bioengineered assembloid (ASM) system combining glioblastoma (GBM) cells in oxidized alginate (OA) microgels with dorsal organoids (DOs). This model simulates brain tumor‐host interactions, revealing enhanced GBM invasion, altered gene expression, and aggressive infiltration patterns, demonstrating ASM as a valuable platform for ...

Expenditure Switching and Exchange Rate Policy [PDF]

open access: yes
Nominal exchange rate changes can lead to 'expenditure switching' when they change relative international prices. A traditional argument for flexible nominal exchange rates posits that when prices are sticky in producers' currencies, nominal exchange ...

Effects of Low Dose Neutron-Gamma Field on Cell Cycle and Damage of Human Lymphocytes

open access: yesDose-Response
Purpose: The aim is to investigate the response of peripheral blood lymphocytes to a low-dose neutron-gamma field. Methods: The human peripheral blood was exposed to low-dose neutron-gamma radiation ex vivo.

A Fully Human Engineered Bone Niche With Endogenous Osteoclastogenesis Reveals Osteoclast‐Dependent Osteomimicry in Prostate Cancer Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
A human 3D bone niche integrating osteoblasts and osteoclasts enables co‐culture with prostate cancer cell lines and patient‐derived organoids. The engineered niche (i) models aspects of reciprocal phenotypic regulation between osteoblasts and cancer cells, (ii) captures osteoclast‐enhanced osteomimicry in tumor cells, and (iii) establishes a ...

Neutrophil‐Mimetic MRI Enables Ultra‐Early Detection of Vascular Inflammation After Stroke

open access: yesAdvanced Healthcare Materials, EarlyView.
In this study, we developed neutrophil‐mimetic MRI probes that detect ultra‐early neuroinflammation following ischemic stroke by targeting E‐selectin. Within seconds of their injection, these microparticles mimic initial leukocyte adhesion to the activated cerebral endothelium.

Immunoinflammatory Mechanisms and Biocompatibility of Bioactive Dental Biomaterials: From Fundamental Insights to Clinical Translation

open access: yesAdvanced Healthcare Materials, EarlyView.
Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.

On the endogeneity of exchange rate regimes [PDF]

open access: yes
The literature has identified three main approaches to account for the way exchange rate regimes are chosen: i) the optimal currency area theory; ii) the financial view, which highlights the consequences of international financial integration; and iii ...

Matrix Stiffness Directs Stemness Signatures in Breast Cancer

open access: yesAdvanced Healthcare Materials, EarlyView.
We built lab‐grown breast cancer models to study how the stiffness of the tumor's surroundings influences cancer behavior. Softer environments encouraged more stem‐like, drug‐resistant cells, while stiffer ones kept cells more differentiated. These findings show that tissue mechanics drive cancer diversity and drug resistance, offering new insights for
