Zhonghua Yi Xue Yi Chuan Xue Za Zhi

August 2024

Institute of Pediatrics, South China University, Department of Medical Genetics, Hunan Provincial Children's Hospital, Changsha, Hunan 410007, China.

Article Synopsis
  • - Congenital joint synostosis (CJS) is a condition caused by improper joint development during embryonic growth, with two main types: syndromic (sCJS) linked to broader disorders and non-syndromic (nsCJS) characterized solely by joint issues.
  • - Syndromic CJS is associated with chromosomal and single-gene disorders, while non-syndromic CJS primarily involves only joint abnormalities.
  • - The review focuses on non-syndromic CJS, identifying seven genes linked to the condition and exploring their clinical implications, genetic patterns, and potential roles in joint development signaling pathways.

Skin-Interfaced Bifluidic Paper-Based Device for Quantitative Sweat Analysis.

Adv Sci (Weinh)

March 2024

School of Materials Science and Engineering, Xiangtan University, Xiangtan, Hunan, 411105, China.

The erratic, intermittent, and unpredictable nature of sweat production, resulting from physiological or psychological fluctuations, poses intricacies to consistently and accurately sample and evaluate sweat biomarkers. Skin-interfaced microfluidic devices that rely on colorimetric mechanisms for semi-quantitative detection are particularly susceptible to these inaccuracies due to variations in sweat secretion rate or instantaneous volume. This work introduces a skin-interfaced colorimetric bifluidic sweat device with two synchronous channels to quantify sweat rate and biomarkers in real-time, even during uncertain sweat activities.
