BACKGROUND: There is widespread evidence of the purported benefits of employee organizational commitment (EOC) and its impact on both individual and organizational performance. This study contributes to this literature by providing a unique insight into this relationship, focusing on the interrelationship between EOC with hospital performance and the role of the provision of adequate facilities in eliciting EOC. PURPOSE: The aim of this study was to introduce and empirically examine a new theoretical model in which it is argued that the performance of hospitals with regard to the provision of adequate facilities (medical facilities, support facilities, and staff resources) influences the level of EOC, which in turn influences hospital performance with regard to patient care and operational effectiveness...

OBJECTIVES: Poor adherence to psychological treatment for insomnia is common and limits treatment gains. Very little is known about predictors of adherence among patients with chronic pain, although adherence is theorized to be more critical and more challenging for these patients. This secondary data analysis examines predictors of drop-out and therapy nonattendance in an osteoarthritis population receiving psychological treatment for insomnia and pain. METHODS: Data were analyzed from the "Lifestyles" trial, a randomized controlled trial of a 6-week group cognitive behavioral pain coping skills intervention (CBT-P), group cognitive-behavioral therapy for pain and insomnia (CBT-PI), and an education only attention control group (EOC)...

Antagonizing the oncogenic effects of human epidermal growth factor receptor 2 (HER2) with current anti-HER2 agents has not yet yielded major progress in the treatment of advanced HER2-positive epithelial ovarian cancer (EOC). Using preclinical models to explore alternative molecular mechanisms affecting HER2 overexpression and oncogenicity may lead to new strategies for EOC patient treatment. We previously reported that phosphatidylcholine-specific phospholipase C (PC-PLC) exerts a pivotal role in regulating HER2 overexpression in breast cancer cells...

Insulin and IGFs play an important role in cancer initiation and progression, including ovarian cancer (OC). Epithelial ovarian cancer (EOC) is the most frequent type of OC in women and it is the most lethal gynecological malignancy worldwide. Generally, insulin is associated with metabolism, whereas Insulin like growth factors (IGFs) are involved in cell proliferation. Hence, Insulin-like growth factor binding proteins (IGFBPs) determines the bioavailability of IGFs in circulation. The interplay between these molecules such as insulin, IGFs, IGFBPs and insulin-like growth factor receptor 1 (IGF1R) may be crucial for ovarian cancer cell biology and cancer progression...

BACKGROUND: Epithelial ovarian cancer (EOC) is the leading cause of death from gynaecologic malignancies and has a poor prognosis due to metastasis. Drugs targeting the angiogenesis pathway significantly improve patient outcome. However, the key factors linking angiogenesis and metastasis have not been elucidated. In this study, we found Tie2 expressing monocytes (CD14(+)Tie2(+), TEMs) as key contributors to angiogenesis and metastasis of EOC. METHODS: Tissue slides were evaluated by immunofluorescence for the presence of total tissue macrophages and TEMs...

A reactive barrier that consisted of vegetable compost, iron oxide and clay was installed in an infiltration basin to enhance the removal of emerging organic compounds (EOCs) in the recharge water. First-order degradation rates and retardation factors were jointly estimated for 10 compounds using a multilayer reactive transport model, whose flow and conservative transport parameters were previously estimated using hydraulic head values and conservative tracer tests. Reactive transport parameters were automatically calibrated against the concentration of EOCs measured at nine monitoring points...

Recent high-profile activations of the US Centers for Disease Control and Prevention (CDC) Emergency Operations Center (EOC) include responses to the West African Ebola and Zika virus epidemics. Within the EOC, emergency responses are organized according to the Incident Management System, which provides a standardized structure and chain of command, regardless of whether the EOC activation occurs in response to an outbreak, natural disaster, or other type of public health emergency. By embedding key scientific roles, such as the associate director for science, and functions within a Scientific Response Section, the current CDC emergency response structure ensures that both urgent and important science issues receive needed attention...

Epithelial ovarian cancer (EOC) can be stratified according to the stages of epithelial-mesenchymal transition (EMT). Here, we aim to identify tyrosine kinases (TKs) in EOC that correlate with the EMT subtypes. By gene expression microarray, we analyzed the expression levels of tyrosine kinases in EOC cell lines in correlation with EMT. Among the candidate TKs identified, DDR1 was expressed mainly in EOC cells with an Epithelial phenotype. Its expression was validated by qPCR, ELISA and western blotting. Using Infinium HumanMethylation27K BeadChip array and pyrosequencing, we further analyzed the CpG methylation levels at the DDR1 promoter in EOC cells and found that the CpG methylation levels of DDR1 promoter correlated negatively with the expression of DDR1 along the EMT spectrum...
