The Impact of Altered Gravity and Vibration on Endothelial Cells During a Parabolic Flight

Cellular Physiology and Biochemistry, 2013
Background: Endothelial cells (EC) cultured under altered gravity conditions show a cytoskeletal disorganization and differential gene expression (short-term effects), as well as apoptosis in adherently growing EC or formation of tubular 3D structures ...

Nathaniel Culverwell's stoic theory of common notions

The Southern Journal of Philosophy, EarlyView.
Abstract This article takes a closer look at the theory of knowledge developed by Nathaniel Culverwell in his 1652 Elegant and Learned Discourse of the Light of Nature. Based on Culverwell's endorsement of Edward Herbert of Cherbury against Plato and Aristotle, his critical reception of René Descartes, and his contributions to a controversy between ...

Poetic Sociology

Sociological Forum, EarlyView.
ABSTRACT Can sociologists feel? Sociological writing can be beautiful, making us think differently about people, processes, and structures. Yet traditional academic writing that does this is rare. For example, most articles adhere to a jargon‐filled format and structure that mimics a detached and disciplined writer.

Angry Birds Revisited: Making Connections Between Mathematics and Physics Meaningful and Joyful

School Science and Mathematics, EarlyView.
ABSTRACT Connecting mathematical reasoning with physical sensemaking remains challenging for many students, and interdisciplinary STEM instruction often struggles to integrate disciplines without one overshadowing the other. This paper presents a digital task sequence designed to support students in making meaningful and joyful connections between ...

Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Pharmacological Stimulation of Type 5 Adenylyl Cyclase Stabilizes Heart Rate Under Both Microgravity and Hypergravity Induced by Parabolic Flight

Journal of Pharmacological Sciences, 2012
We previously demonstrated that type 5 adenylyl cyclase (AC5) functions in autonomic regulation in the heart. Based on that work, we hypothesized that pharmacological modulation of AC5 activity could regulate the autonomic control of the heart rate under

Box–Behnken optimization and ANN‐ANFIS integrated modelling for transesterification using thermally activated basic oxygen furnace slag catalyst

The Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5991-6006, November 2026.
Abstract Global energy demand and environmental concerns have intensified the search for renewable and sustainable energy sources. This study thus, focuses on optimizing the transesterification process of waste cooking oil (WCO) using thermally activated basic oxygen furnace slag catalyst calcined at 850°C (BOF 850). The optimization and modelling were
