Novels are one humanities resource available to educators in health disciplines to support student reflection on their own professional practice and therapeutic relationships with patients. An interdisciplinary team, including nurses, a physician, and an English instructor, carried out an interpretive study of the use of a novel by clinical nursing instructors in an undergraduate practicum course. Students placed in assisted living or long term care facilities for the elderly were expected to read a contemporary work, Exit Lines, by Joan Barfoot, which is set in a comparable facility...

REVIEW
Howard C Becker
Stress is commonly regarded as an important trigger for relapse and a significant factor that promotes increased motivation to drink in some individuals. However, the relationship between stress and alcohol is complex, likely changing in form during the transition from early moderated alcohol use to more heavy uncontrolled alcohol intake. A growing body of evidence indicates that prolonged excessive alcohol consumption serves as a potent stressor, producing persistent dysregulation of brain reward and stress systems beyond normal homeostatic limits...

Multiple studies have documented that Enhancer of zeste homolog 2 (EZH2) could play a role in inflammation and a wide range of malignancies; however, the underlying mechanisms remain largely unaddressed. Microglial activation is a key process in the production and release of numerous pro-inflammatory mediators that play important roles in inflammation and neurodegeneration in the central nervous system (CNS). Therefore, our aim was to investigate whether inhibition of EZH2 with the selective small molecule inhibitor EPZ-6438 protects against neonatal microglial activation...

Pharmacoresistant seizures and cytotoxic cerebral edema are serious complications of ischemic and traumatic brain injury. Intraneuronal Cl(-) concentration ([Cl(-)]i) regulation impacts on both cell volume homeostasis and Cl(-)-permeable GABAA receptor-dependent membrane excitability. Understanding the pleiotropic molecular determinants of neuronal [Cl(-)]i - cytoplasmic impermeant anions, polyanionic extracellular matrix (ECM) glycoproteins, and plasmalemmal Cl(-) transporters - could help the identification of novel anticonvulsive and neuroprotective targets...

Traditionally, the efficacy of cancer treatment in patients with advance or metastatic disease in clinical studies has been studied using overall survival (OS) and more recently tumor-based endpoints such as progression-free survival, measurements of response to treatment. However, these seem not to be the relevant clinical endpoints in current situation if such endpoints were no validated as surrogate of OS to demonstrate the clinical efficacy. Appropriate, meaningful, primary patient-oriented and patient-reported endpoints that adequately measure the effects of new therapeutic interventions are then crucial for the advancement of clinical research in metastatic colorectal cancer to complement the results of tumor-based endpoints...

WHAT IS KNOWN AND OBJECTIVE: Warfarin is a widely used anticoagulant with a narrow therapeutic index. Polymorphisms in the VKORC1, CYP2C9 and CYP4F2 genes have been verified to correlate with warfarin stable dosage (WSD). Whether any other genes or variants affect the dosage is unknown. The aim of our study was to investigate the relationship between GGCX, miR-133 variants and the WSD in Han Chinese patients with mechanical heart valve replacement (MHVR). METHODS: A total of 231 patients were enrolled in the study...

Hepatocellular carcinoma (HCC) is the fifth leading cause of cancer mortality worldwide. Several studies have investigated the relationship between (18)F-fluorodeoxyglucose ((18)F-FDG) uptake on positron emission tomography and the prognosis of patients with HCC, although the relationship between (18)F-FDG uptake and expression of EMT-related proteins in these patients remains unclear. We retrospectively enrolled 116 patients with HCC treated by curative surgical resection and who underwent (18)F-FDG positron emission tomography/computed tomography (PET/CT) for preoperative staging...

Cardiovascular disease is a leading cause of death with increasing economic burden. The pathogenesis of cardiovascular diseases is complex, but can arise from genetic and/or environmental risk factors. This can lead to dysregulated gene expression in numerous cell types including cardiomyocytes, endothelial cells, vascular smooth muscle cells, and inflammatory cells. While initial studies addressed transcriptional control of gene expression, epigenetics has been increasingly appreciated to also play an important role in this process through alterations in chromatin structure and gene accessibility...

A main challenge in chemotherapy is to determine the in cellulo parameters modulating the drug concentration required for therapeutic action. It is absolutely urgent to understand membrane permeation and intracellular concentration of antibiotics in clinical isolates: passing the membrane barrier to reach the threshold concentration inside the bacterial periplasm or cytoplasm is the pivotal step of antibacterial activity. Ceftazidime (CAZ) is a key molecule of the combination therapy for treating resistant bacteria...

Jeffrey Noebels
Ion channel genes, originally implicated in inherited excitability disorders of muscle and heart, have captured a major role in the molecular diagnosis of central nervous system disease. Their arrival is heralded by neurologists confounded by a broad phenotypic spectrum of early-onset epilepsy, autism, and cognitive impairment with few effective treatments. As detection of rare structural variants in channel subunit proteins becomes routine, it is apparent that primary sequence alone cannot reliably predict clinical severity or pinpoint a therapeutic solution...

Background: Although the role of epigenetic abnormalities has been studied for several years in cancer genesis and development, epigenetic-targeting drugs have historically failed to demonstrate efficacy in solid malignancies. However, successful targeting of chromatin remodeling deficiencies, histone writers and histone reader alterations has been achieved very recently using biomarker-driven and mechanism-based approaches. Epigenetic targeting is now one of the most active areas in drug development and could represent novel therapeutic opportunity for up to 25% of all solid tumors...

BACKGROUND: Difficulty in emotion regulation is a hallmark feature of patients with borderline personality disorder (BPD). Therefore, change in the frequency of certain patients' coping strategies-aiming at emotion regulation-are among the most promising mechanisms of change in treatments for BPD. In parallel, it was highlighted that therapist responsiveness significantly contributed to outcome across treatment approaches (Stiles, 2009). Based on a randomized controlled trial (Kramer et al...

Although most human cancers display a single histology, there are unusual cases where two or more distinct tissue types present within a primary tumor. One such example is metaplastic breast carcinoma, a rare but aggressive cancer with a heterogenous histology, including squamous, chondroid, and spindle cells. Metaplastic carcinomas often contain an admixed conventional ductal invasive or in situ mammary carcinoma component, and are typically triple-negative for estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2 (HER-2) amplification/overexpression...
