Quantitative assessment of impedance tomography for temperature measurements in hyperthermia

, 1992
The objective of this study is a non-invasive assessment of the thermal dose in hyperthermia. Electrical impedance tomography (EIT) has previously been given a first trial as a temperature monitoring method together with microwave-induced hyperthermia ...

Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions

Advanced Materials, EarlyView.
Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

Graphene Oxide Nanosheets for Localized Hyperthermia—Physicochemical Characterization, Biocompatibility, and Induction of Tumor Cell Death

Cells, 2020
Background: The main goals of cancer treatment are not only to eradicate the tumor itself but also to elicit a specific immune response that overcomes the resistance of tumor cells against chemo- and radiotherapies. Hyperthermia was demonstrated to chemo-

Soft, Degradable, and Magnetic Microcarriers for Encapsulation and Guided Transport of Drugs and 3D Spheroids

Advanced Materials, EarlyView.
This work presents soft, degradable hydrogel microcarriers that combine magnetic responsiveness with the ability to host multiple therapeutic and cellular components. Produced by droplet microfluidics, the carriers maintain structural integrity during manipulation, permit controlled breakdown under physiological conditions, and enable guided motion for

SP0083 Effort-induced hyperthermia: similarities with malignant hyperthermia [PDF]

Annals of the Rheumatic Diseases, 2001
Effort-induced hyperthermia, also called exertional heat stroke (EHS) is due to an imbalance between internal heat production and heat loss, generally exacerbated by several factors such as inadequate fluid, caloric, and/or electrolyte intake, and is associated with a classical symptomatology, i.e.

The effect of hyperthermia on the phosphoinositide signalling system of tumour cells [PDF]

, 1994
The effect of heat on the phosphoinositide signalling pathway was investigated in CHO-K1 cells and WRK-1 cells. Heat caused a decrease in 1,2-diacylglycerol (1,2- DAG) levels but did not have any effect on monoacylglycerol (MAG) levels in both cell types.

Estimation of the temperature field in laser-induced hyperthermia experiments with a phantom [PDF]

, 2018
Background: One of the challenges faced during the hyperthermia treatment of cancer is to monitor the temperature distribution in the region of interest. The main objective of this work was to accurately estimate the transient temperature distribution in

Flexible Implantable Silicon Carbide Multi‐Electrode Array (MEA) for Cell Multichannel Recording and Cell Ablation

Advanced Materials Technologies, EarlyView.
Flexible silicon carbide (SiC) microelectrode arrays enable high‐fidelity, multichannel cell extracellular recording and precise localized ablation. SiC has been extensively evaluated to persist long‐term in chronic physiological conditions while remaining robust, with excellent electrical and electrochemical stability.
