The morphological characteristics of birds are an important tool for studying their adaptation and evolution. The morphological evolution of a clade is not only constrained by the phylogenetic relationship, but also influenced by ecological factors and interspecific competition. is a group of small nectar-eating birds with obvious sexual dimorphism.

Hatred out of love or love can be all-inclusive? Moderating effects of employee status and organizational affective commitment on the relationship between turnover intention and CWB.

Owing to the prevalence of flexible employment practices around the world and increasingly loose employee-organization relationships, employee turnover intention is gradually becoming normalized. This study aimed to examine the counterproductive work behaviors (CWB) of employees with turnover intention in the hybrid employment context. Drawing on the psychological contract process perspective, this research endeavored to examine whether higher turnover intention is associated with greater levels of CWB and to determine whether and how the association between turnover intention and CWB differs across temporary and permanent workers by considering organizational affective commitment.

Why and When Temporary Workers Engage in More Counterproductive Work Behaviors with Permanent Employees in Chinese State-Own Enterprise: A Social Identity Perspective.

Why do temporary workers sharing the same working conditions as permanent employees still frequently engage in deviant behaviors that negatively affect the organization's interests? Drawing on the theory of social identity, this articlr discusses the relationships among employment status, organizational identification, and counterproductive work behavior. Time-lagged data were collected from sample of 210 dyads of employees and corresponding supervisors from a large Chinese state-owned service company, to test hypothesis. Results showed that temporary workers engage in counterproductive work behaviors more frequently than permanent employees, and organizational identification plays a mediating role in this process.

Two naturally derived small molecules disrupt the sineoculis homeobox homolog 1-eyes absent homolog 1 (SIX1-EYA1) interaction to inhibit colorectal cancer cell growth.

Background: Emerging evidence indicates that the sineoculis homeobox homolog 1-eyes absent homolog 1 (SIX1-EYA1) transcriptional complex significantly contributes to the pathogenesis of multiple cancers by mediating the expression of genes involved in different biological processes, such as cell-cycle progression and metastasis. However, the roles of the SIX1-EYA1 transcriptional complex and its targets in colorectal cancer (CRC) are still being investigated. This study aimed to investigate the roles of SIX1-EYA1 in the pathogenesis of CRC, to screen inhibitors disrupting the SIX1-EYA1 interaction and to evaluate the efficiency of small molecules in the inhibition of CRC cell growth.

The Effect of Job Security on Deviant Behaviors in Diverse Employment Workplaces: From the Social Identity Perspective.

Organizational scholars concur that job security can attach employees to a workplace and improve their job quality. The relationship between job security and employees' deviant behaviors in the workplace, such as counterproductive work behavior (CWB), lacks insights into how or why this occurs, especially in a diversified employment context. To address these limitations, we developed a theoretical model of job security impact on employees' CWB from the perspective of social identity.

A meta-analysis of randomized controlled trials of a traditional Chinese medicine prescription, modified RunChang-Tang, in treating functional constipation.

Background: Modified Runchang-Tang (MRCT), a Chinese herbal medicine, is widely used to treat functional constipation (FC), which is a common digestive system disease. However, its efficacy has not been evaluated systematically and objectively. Thus, a meta-analysis was conducted to assess the efficacy and safety of MRCT for treating functional constipation.

Job Security and Organizational Citizenship Behaviors in Chinese Hybrid Employment Context: Organizational Identification Versus Psychological Contract Breach Perspective Differences Across Employment Status.

The goal of the present research was to identify the mechanism through which job security exerts its different effects on organizational citizenship behaviors (OCB) among contract and permanent employees from social identity and social exchange perspectives. Our research suggests two distinct, yet related explanatory mechanisms: organizational identification and psychological contract breach, to extend the job security literature by examining whether psychological contract breach and organization identity complement each other and explaining the mechanism of different behaviors response to job security across employment status. Data were collected from 211 Chinese employees and 61 supervisory ratings of OCBs.

Modified Van Assche magnetic resonance imaging-based score for assessing the clinical status of anal fistulas.

The modified Van Assche magnetic resonance imaging (MRI)-based score is a feasible system to assess the clinical status of anal fistulas in Crohn disease. In this study, we evaluated this score's association with clinical status in patients with anal fistulas (AFs).We included all patients with AF who underwent contrast-enhanced pelvic MRI and surgery between January 2011 and December 2016.

The CARM1-p300-c-Myc-Max (CPCM) transcriptional complex regulates the expression of and affects the stability of CRL4 E3 ligases in colorectal cancer.

The transcription factor c-Myc and two cullin family members CUL4A/4B function as oncogenes in colorectal cancer. Our recent publication reveals that c-Myc specifically activates the expression of through binding to their promoters. However, the underlying mechanism of how c-Myc actions in this process is still unknown.

Inflammation and DNA Methylation-Dependent Down-Regulation of miR-34b-5p Mediates c-MYC Expression and CRL4 E3 Ligase Activity in Colitis-Associated Cancer.

miRNAs, a well-known group of noncoding RNAs, contribute to the pathogenesis of multiple diseases, including colitis-associated cancer (CAC). Our recent findings indicate that proinflammatory cytokines up-regulate c-MYC level, which subsequently activates cullin 4A and 4B (CUL4A/4B) and CRL4 E3 ligases and promotes ubiquitination of suppression of tumorigenicity 7 in CAC. Herein, we identified and proved that miR-34b-5p can directly target c-MYC.

Application of the Albumin-Bilirubin Grade in Predicting the Prognosis of Patients With Hepatocellular Carcinoma: A Systematic Review and Meta-Analysis.
