Nanodiamond Quantum Sensors for Probing Free Radical Biology

Advanced Functional Materials, EarlyView.
Free radicals play key roles in cellular signaling and disease but remain difficult to measure in living systems. Nanodiamonds (NDs) with nitrogen‐vacancy (NV) centers enable quantum sensing of local magnetic noise via T₁ relaxometry, providing nondestructive radical detection in living cells.

Tissue‐Stimulator Platform for Electrically Stimulating Pancreatic β‐Cells for Long‐Term Functional Regulation

Advanced Functional Materials, EarlyView.
We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

Multi‐Scale Interface Engineering of MXenes for Multifunctional Sensory Systems

Advanced Functional Materials, EarlyView.
MXenes, as two‐dimensional transition metal carbides and nitrides, demonstrate remarkable capabilities for multifunctional sensing applications. This review systematically examines multi‐scale interface engineering approaches that enhance sensing performance, enable diverse detection functionalities, and improve system‐level compatibility in MXene ...

Physiologic Adaptations to Pregnancy

Neurologic Clinics, 2012
Pregnancy leads to diverse physiologic changes to accommodate the demands of the developing fetoplacental unit, which affect many major organ systems. Understanding these physiologic adaptations to pregnancy is important for all clinicians because they have important implications for the diagnosis and management of various disorders.

Physiologic Adaptations of Pregnancy

American Journal of Reproductive Immunology, 1992
ABSTRACT: Normal pregnancy changes include physiologic anemia, leukocytosis, and thrombocytopenia. Cardiac rate and stroke volume increase, vascular resistance falls, and creatinine clearance markedly rises. Thyroid binding globulin and Cortisol binding globulin both increase, as do complement proteins and fibrinogen, the latter resulting in a ...

Physiological Adaptation to the Environment

Journal of Animal Science, 1989
The ability of an animal to cope with new environments arises from its capacity to respond to environmental variables and maintain body equilibrium (homeostasis). Each compensating mechanism depends on, and is a part of, a physiological feedback process.

Physiological Adaptation

1993
Abstract This contribution is concerned with the changes which occur in the individual human organism when it experiences new environments. Many of these changes, though by no means all, facilitate living in the new environment and are recognized as components of’individual adaptability’.

Physiological Adaptations to Weightlessness

Exercise and Sport Sciences Reviews, 1990
The aspiration to travel beyond the atmosphere is like the desire to study the ocean floor, the interior of the Earth's crust, to invent a submarine, to fly through the air, improve life, treat disease, and explore the heavens.

Physiological adaptive strategies

1999
Abstract Little is yet known about the sense physiology of subterranean mammals. However, it is now evident in subterranean mammals, as elsewhere, that regression and progression evolution are intimately coupled, and structural and functional sense organs and brain reductions are linked with structural and functional expansions or ...
