molecular permeation of liquid cationic polymers into solid anionic polymer films enabling self-adaptive adhesion of hydrogel biosensors.

Self-adaptive adhesion is essential for hydrogel sensors. However, the traditional protocol involves covering a pre-prepared hydrogel sensor on a tested surface. As a result, the sensor cannot achieve self-adaptive adhesion owing to an air-layer hindrance between the sensor and tested surface, which inevitably leads to the loss of critical biological signals.

Preliminary evaluation of a new initiative to centralize colorectal cancer care during the COVID-19 epidemic in Shanghai, China: a retrospective study.

Background: A novel colorectal cancer center (CCC) was developed in the Shanghai Tenth People's hospital of Tongji University during the COVID-19 epidemic. In this study, we aimed to evaluate the CCC model in terms of three aspects.

Methods: This retrospective study used data from the Shanghai Tenth People's hospital patient databases.

The impact of the COVID-19 pandemic on physical and mental health in the two largest economies in the world: a comparison between the United States and China.

The broad impact of the COVID-19 on self-reported daily behaviors and health in Chinese and US samples remains unknown. This study aimed to compare physical and mental health between people from the United States (U.S.

A chain mediation model on COVID-19 symptoms and mental health outcomes in Americans, Asians and Europeans.

The novel Coronavirus-2019 (COVID-19) was declared a pandemic by the World Health Organization (WHO) in March 2020, impacting the lifestyles, economy, physical and mental health of individuals globally. This study aimed to test the model triggered by physical symptoms resembling COVID-19 infection, in which the need for health information and perceived impact of the pandemic mediated the path sequentially, leading to adverse mental health outcomes. A cross-sectional research design with chain mediation model involving 4612 participants from participating 8 countries selected via a respondent-driven sampling strategy was used.

The impact of COVID-19 pandemic on physical and mental health of Asians: A study of seven middle-income countries in Asia.

The coronavirus disease (COVID-19) pandemic has impacted the economy, livelihood, and physical and mental well-being of people worldwide. This study aimed to compare the mental health status during the pandemic in the general population of seven middle income countries (MICs) in Asia (China, Iran, Malaysia, Pakistan, Philippines, Thailand, and Vietnam). All the countries used the Impact of Event Scale-Revised (IES-R) and Depression, Anxiety and Stress Scale (DASS-21) to measure mental health.

Na⁺-Ca²⁺ exchanger mediates ChR2-induced [Ca²⁺]i elevation in astrocytes.

Intracellular Ca(2+) elevation resulting from different Ca(2+) pathways may play different roles in astrocyte functions. Channelrhodopsin-2 (ChR2), a light-gated cation channel, has been used to selectively stimulate astrocytes by inducing intracellular Ca(2+) ([Ca(2+)]i) elevation, but the exact underlying mechanism is still unclear. We found that in the absence of extracellular Ca(2+), light stimulation failed to induce [Ca(2+)]i elevation in astrocytes expressed ChR2.
