Biomimetic delivery of signals for bone tissue engineering

Bone tissue engineering is an exciting approach to directly repair bone defects or engineer bone tissue for transplantation.Biomaterials play a pivotal role in providing a template and extracellular environment to support regenerative cells and promote tissue regeneration. A variety of signaling cues have been identified to regulate cellular activity, tissue development, and the healing process. Numerous studies and trials have shown the promise of tissue engineering, but successful translations of bone tissue engineering research into clinical applications have been limited, due in part to a lack of optimal delivery systems for these signals. Biomedical engineers are therefore highly motivated to develop biomimetic drug delivery systems, which benefit from mimicking signaling molecule release or presentation by the native extracellular matrix during development or the natural healing process. Engineered biomimetic drug delivery systems aim to provide control over the location, timing, and release kinetics of the signal molecules according to the drug's physiochemical properties and specific biological mechanisms. This article reviews biomimetic strategies in signaling delivery for bone tissue engineering, with a focus on delivery systems rather than specific molecules. Both fundamental considerations and specific design strategies are discussed with examples of recent research progress, demonstrating the significance and potential of biomimetic delivery systems for bone tissue engineering.

Response Inhibition and Memory Retrieval of Emotional Target Words: Evidence from an Emotional Stop-Signal Task

Previous research suggests that emotional stimuli capture attention and guide behavior often automatically. The present study investigated the relationship between emotion-driven attention capture and motor response inhibition to emotional words in the stop-signal task. By experimental variations of the onset of motor response inhibition across the time-course of emotional word processing, we show that processing of emotional information significantly interferes with motor response inhibition in an early time-window, previously related to automatic emotion-driven attention capture. Second, we found that stopping reduced memory recall for unpleasant words during a subsequent surprise free recall task supporting assumptions of a link between mechanisms of motor response inhibition and memory functions. Together, our results provide behavioral evidence for dual competition models of emotion and cognition. This study provides an important link between research focusing on different sub-processes of emotion processing (from perception to action and from action to memory).

Introduction

Over the past 30 years, there has been a general change of emphasis in toxicology from the traditional concerns with poisons and antidotes to understanding the chronic toxic effects associated with exposure to environmental agents. The major cause of this shift was a focusing of public interest on long-term health effects of man-made chemicals. This public awareness was motivated in part by the successes of public health sanitarians in controlling infectious diseases (with the recent exception of AIDS), which resulted in the lengthening of life expectancy in the population (Hart and Turturro, 1990). This change in emphasis has radically altered the scientific methods Used in toxicology. There are basic differences in evaluating short-term and long-term consequences of toxic exposure. Interestingly, techniques similar to those used to understand the effects of long-term toxicity are also useful in understanding aging (Hart and Turturro, 1988). Factors that contribute to these differences include the comp

Chemical interaction motivated structure design of layered metal carbonate hydroxide/MXene composites for fast and durable lithium ion storage

Rational architecture design has turned out to be an effective strategy in improving the electrochemical performance of electrode materials for batteries.However,an elaborate structure that could simultaneously endow active materials with promoted reaction reversibility,accelerated kinetic and restricted volume change still remains a huge challenge.Herein,a novel chemical interaction motivated structure design strategy has been proposed,and a chemically bonded Co(CO_(3))_(0.5)OH·0.11 H_(2)O@MXene(CoCH@MXene)layered-composite was fabricated for the first time.In such a composite,the chemical interaction between Co^(2+)and MXene drives the growth of smaller-sized CoCH crystals and the subsequent formation of interwoven CoCH wires sandwiched in-between MXene nanosheets.This unique layered structure not only encourages charge transfer for faster reaction dynamics,but buffers the volume change of CoCH during lithiation-delithiation process,owing to the confined crystal growth between conductive MXene layers with the help of chemical bonding.Besides,the sandwiched interwoven CoCH wires also prevent the stacking of MXene layers,further conducive to the electrochemical performance of the composite.As a result,the as-prepared CoCH@MXene anode demonstrates a high reversible capacity(903.1 mAh g^(-1)at 100 mA g^(-1))and excellent cycling stability(maintains 733.6 mAh g^(-1)at1000 mA g^(-1)after 500 cycles)for lithium ion batteries.This work highlights a novel concept of layerby-layer chemical interaction motivated architecture design for futuristic high performance electrode materials in energy storage systems.

跑步,我生命的一部分

在经历了一系列致命的心脏问题后,他总是会设定一个又一个的目标来激励自己康复。在他看来,没有运动和马拉松,生命也就意味着终止。Randy Lazer started running back in 1990 as a way to step into a healthier lifestyle.As an asthma sufferer who didn't work out much,he took it one step at a time,going out for a half-mile jog his first time on the road.It took about four tries for him to make it a full mile,but that only motivated him to go farther.

Introduction of the special issue on COVID-19 and the financial and economic systems

A large number of submissions were received in response to this call for paper on the theme of COVID-19 and the financial and economic systems.Naturally,the COVID-19 pandemic has dominated much of the recent finance and economics literature.This call for paper was motivated by early special issues on the COVID-19 business and economics themes such as those published by Sha and Sharma(2020)and Sharma and Sha(2020,2021).This editorial has two parts.In the first part I summarize the key outcomes from each of the papers.In the second part,I identify an agenda for future research that has emanated from this special issue papers.

Motivation and Demotivation in L2 Learning

Motivation has been regarded as one of the most important factors in the process of second language leaming in recent years. This paper aims to find out the motivation intensity in students＇ language leaming and why some students become demotivated in the learning process. According to the study, the reasons why some motivated students become demotivated are multifaceted. But we found teachers played an important role in this process. Most students depend greatly on their teachers to motivate them. So teachers should attach more importance in this field and try to find out ways to maintain the high motivation and create situations to make students become more motivated.

Writings with Love and Responsibility

AFTER the outbreak of the novel coronavirus epidemic in early 2020,many foreigners living in China wrote down their own experiences and shared their thoughts that have become so common during this traumatic time:responsibility,trust,and love.Some of these foreigners chose to stay in China when the epidemic began to rage in the country.What was it that motivated their choices?When asked by their families or the media,what would they say?How did they occupy their time during this difficult period?

Demonizing "Made-in-China" Found Politically Motivated

"Formaldehyde", a very strange word both in English or in Chinese, has all of sudden become a headline blowout. " You have all hairy body, why call others demons?" as Chinese saying goes, meaning you have a lot of problems with the same thing, how can you stand easy to reproach others? Demonizing "Made-in-China" is politically motivated!" That's what one would often hear from Chinese manufacturers amid the reciprocal recalls of the alleged unsafe products from each other. What's in store for "Made-in-China" in the future?

A Study on Chinese Students＇ Perceptual Learning Styles, Ideal L2 Self, and L2 Motivated L2 Behavior

This study investigates Chinese elementary, middle, and high school students＇ L2 perceptual learning styles, imagination, ideal L2 self, and motivated L2 behavior. A perceptual learning style and L2 learning motivation questionnaire was administered to 1,667 students from elementary to high school. Statistical results revealed that Chinese elementary, middle, and high school students were more in favor of a visual learning style in comparison to their auditory and kinesthetic learning styles. This visually oriented style was significantly correlated with their ideal L2 self and motivated L2 behavior. The sequential regression analysis results indicated that the ideal L2 self and visual learning style were the most meaningful predictors for Chinese students＇ motivated L2 behavior. This study suggests that teachers need to help students create and maintain their ideal L2 self and facilitate their L2 learning motivation by providing more adequate visual teaching materials.
