Recent Advances in Biodegradable Green Electronic Materials and Sensor Applications.

As environmental issues have become the dominant agenda worldwide, the necessity for more environmentally friendly electronics has recently emerged. Accordingly, biodegradable or nature-derived materials for green electronics have attracted increased interest. Initially, metal-green hybrid electronics are extensively studied.

Dynamic Pore Modulation of Stretchable Electrospun Nanofiber Filter for Adaptive Machine Learned Respiratory Protection.

The recent emergence of highly contagious respiratory disease and the underlying issues of worldwide air pollution jointly heighten the importance of the personal respirator. However, the incongruence between the dynamic environment and nonadaptive respirators imposes physiological and psychological adverse effects, which hinder the public dissemination of respirators. To address this issue, we introduce adaptive respiratory protection based on a dynamic air filter (DAF) driven by machine learning (ML) algorithms.

The use of etanercept in a patient with disseminated tuberculosis.

Tumor necrosis factor (TNF) is a central regulator of chronic inflammatory diseases and plays a major role in the host immune system against tuberculosis (TB). TNF antagonists, infliximab and etanercept are effective in treating chronic inflammatory diseases by inhibiting TNF, but increase the risk of TB as a result of immunosuppression. Previous studies have shown that the risk of TB is greater in patients who received infliximab than in those who received etanercept and several hypotheses on the action mechanisms of the two agents have been presented in order to explain this difference in the risk of TB.

A case of post-pregnancy osteoporosis combined with ankylosing spondylitis.

Post-pregnancy osteoporosis is not a common disease and is hard to diagnosis because their specific situation is post-partum and lactation. It commonly occurs on lumbar spine within a few months after the birth of a patient's first child and it could lead to be fracture after minor trauma. Although its etiology is not clear, it would not be of sufficient magnitude to cause fractures unless the woman already had a substantial decrease in bone mass.

No Association between Catalase Gene Polymorphism and Gastric Carcinoma and Hepatocellular Carcinoma in Koreans.

Purpose: Oxidative stress has been implicated in the pathogenesis of various diseases. Catalase is one of the main defense mechanisms against oxidative stress. To examine the possible relationship between oxidative stress, and gastric and hepatocellular carcinomas, HinfI restriction length polymorphism (RFLP) in the human catalase gene was assessed.
