Shape‐Reconfigurable Crack‐Based Strain Sensor with Ultrahigh and Tunable Sensitivity

Advanced Functional Materials, EarlyView.
A highly sensitive crack‐based sensor with tunable strain detection capabilities is demonstrated through controlled nanocrack formation in a line‐patterned shape memory polymer substrate. The sensor design integrates thermoplastic polyurethane and poly(lactic acid), enabling thermo‐responsive reconfiguration of crack geometry.

Five-year outcome of a staged giant Shamblin type III carotid body tumor excision

Journal of Vascular Surgery Cases and Innovative Techniques, 2023
Giant carotid body tumors, defined as those >8 cm in size, are extremely rare. Definitive surgical management is a complex undertaking because these large tumors tend to have grown to envelop cranial nerves and the carotid artery, and few data exist ...

Hydrogel Adhesive Integrated‐Microstructured Electrodes for Cuff‐Free, Less‐Invasive, and Stable Interface for Vagus Nerve Stimulation

Advanced Healthcare Materials, EarlyView.
In this study, a cuff‐free, less‐invasive surgical approach for vagus nerve stimulation (VNS) by combining ultrathin Y‐shaped kirigami electrodes is developed with a chemically cross‐linked hydrogel adhesive (hydrogel‐kirigami). Unlike conventional cuff implantation, which may damage nerves and nearby critical vessels, this new technique minimizes ...

Functional consequences of brain exposure to saturated fatty acids: From energy metabolism and insulin resistance to neuronal damage

Endocrinology, Diabetes &Metabolism, Volume 6, Issue 1, January 2023., 2023
Saturated fatty acids induce insulin resistance in neurons. Neuronal metabolism of palmitic acid alters mitochondrial function. Abstract Introduction Saturated fatty acids (FAs) are the main component of high‐fat diets (HFDs), and high consumption has been associated with the development of insulin resistance, endoplasmic reticulum stress and ...

Non‐Surgical, In‐Stent Membrane Bioelectronics for Long‐Term Intracranial Pressure Monitoring

Advanced Healthcare Materials, EarlyView.
This image shows a sequence of long‐term intracranial pressure monitoring using non‐surgical, in‐stent membrane bioelectronics. Abstract Traditional intracranial pressure (ICP) monitoring methods, using intraventricular catheters, face significant limitations, including high invasiveness, discrete data, calibration complexities, and drift issues, which

Branched‐chain α‐keto acids and glutamate/glutamine: Biomarkers of insulin resistance in childhood obesity

Endocrinology, Diabetes &Metabolism, Volume 6, Issue 1, January 2023., 2023
Insulin resistance (IR) in adolescents with obesity is associated with a sex‐dependent metabolic “signature” comprising the branched‐chain amino acids (BCAAs), glutamate/glutamine, C3/C5 acylcarnitines, and uric acid. Here, we compared the levels of branched‐chain α‐keto acids (BCKAs) and glutamate/glutamine, which are byproducts of BCAA catabolism, as

STUDIES OF CAROTID BODY AND CAROTID SINUS: FINE STRUCTURE OF CAROTID BODY

Nihon Naika Gakkai Zasshi, 1966
古くから頚動脈洞反射にかんする研究は多く, 総頚動脈分岐部には, 圧受容体と化学受容体の存在することは多くの生理学者が認めるものである. これらにかんして, イヌを用いて, 頚動脈洞を刺激し, その血中カテコールアミン体の変動を認め, さらに, 動脈血中の化学成分の変化によつて起こる呼吸反射をみとめ, 先人の業績を確認しながら, 組織像を追究した. ことに, 電顕像および組織化学的方法によつても, 頚動脈体は, 腺でも単なる血管糸球でもなく, 傍神経節でもなく, クローム親和性細胞も認められず, いわゆる頚動脈体と呼称されるのにふさわしい臓器であることを認め, さらに, 頚動脈洞壁の微細構造と比較検討し, 本小体が化学受容体とされて当然のことと結語した.

Nanostructured 316L Stainless Steel Stent Surfaces Improve Corrosion Resistance, and Enhance Endothelization and Hemocompatibility

Advanced Materials Interfaces, EarlyView.
This study investigates the impact of nanostructured surface modification on corrosion resistance, HUVEC functions, and platelet interactions of 316L SS for cardiovascular stents. Nanostructured surfaces enhanced HUVEC proliferation, migration, and angiogenesis‐related gene expression while reducing platelet adhesion and hemolysis.
