The activation of inflammatory cells is controlled at transcriptional and posttranscriptional levels. Posttranscriptional regulation modifies mRNA stability and translation, allowing for elaborate control of proteins required for inflammation, such as proinflammatory cytokines, prostaglandin synthases, cell surface co-stimulatory molecules, and even transcriptional modifiers. Such regulation is important for coordinating the initiation and resolution of inflammation, and is mediated by a set of RNA-binding proteins (RBPs), including Regnase-1, Roquin, Tristetraprolin (TTP), and AU-rich elements/poly(U)-binding/degradation factor 1 (AUF1)...

Precipitation behavior and the quenching sensitivity of a spray deposited Al-Zn-Mg-Cu-Zr alloy during isothermal heat treatment have been studied systematically. Results demonstrate that both the hardness and the ultimate tensile strength of the studied alloy decreased with the isothermal treatment time at certain temperatures. More notably, the hardness decreases rapidly after the isothermal heat treatment. During isothermal heat treatment processing, precipitates readily nucleated in the medium-temperature zone (250-400 °C), while the precipitation nucleation was scarce in the low-temperature zone (<250 °C) and in the high-temperature zone (>400 °C)...

PURPOSE: Positron emission tomography (PET) in non-human primates (NHP) is commonly performed under anesthesia, with sevoflurane being a widely used inhaled anesthetic. PET measurement in NHP can be repeated, and a difference in radioligand kinetics has previously been observed between the first and second PET measurement on the same day using sevoflurane anesthesia. In this study, we evaluated the effect of prolonged sevoflurane anesthesia on kinetics and binding potential (BPND) of [(11)C]raclopride in NHP...

Spinal cord neurons active during locomotion are innervated by descending axons that release the monoamines serotonin (5-HT) and norepinephrine (NE) and these neurons express monoaminergic receptor subtypes implicated in the control of locomotion. The timing, level and spinal locations of release of these two substances during centrally-generated locomotor activity should therefore be critical to this control. These variables were measured in real time by fast-cyclic voltammetry in the decerebrate cat's lumbar spinal cord during fictive locomotion, which was evoked by electrical stimulation of the mesencephalic locomotor region (MLR) and registered as integrated activity in bilateral peripheral nerves to hindlimb muscles...

BACKGROUND: In this study, our aim was to identify molecular aberrations predictive for response to everolimus, an mTOR inhibitor, regardless of tumor type. METHODS: To generate hypotheses about potential markers for sensitivity to mTOR inhibition, drug sensitivity and genomic profiles of 835 cell lines were analyzed. Subsequently, a multicenter study was conducted. Patients with advanced solid tumors lacking standard of care treatment options were included and underwent a pre-treatment tumor biopsy to enable DNA sequencing of 1,977 genes, derive copy number profiles and determine activation status of pS6 and pERK...

Drug regulators around the world make decisions about drug approvability based on qualitative benefit-risk analysis. In this work, a quantitative benefit-risk analysis approach captures regulatory decision-making about new drugs to treat multiple myeloma (MM). MM assessments have been based on endpoints such as time to progression (TTP), progression-free survival (PFS), and objective response rate (ORR) which are different than benefit-risk analysis based on overall survival (OS) due to an increased focus on quality of life instead of quantity of life...

Anterior abdominal wall defects (AAWD) correspond to a wide spectrum of congenital defects affecting 6.3/10,000 pregnancies. They have in common a closure defect of the anterior abdominal wall and can be fatal or expose the fetus and the neonate (NN) to many complications. This study was based on a retrospective study of 22 cases of AAWD collected between May 2009 and December 2014. Its purpose was to specify the importance of prenatal ultrasonography in the diagnosis and prognosis assessment of these defects...

Loss of ovarian function can activate inflammation and lead to insulin resistance (IR). IR is also a core feature of obesity and obesity-associated metabolic dysfunction. Tristetraprolin/zinc finger protein 36 (TTP) interferes with TNF-α production by destabilizing TNF-α mRNA, and mice deficient in TTP develop a complex syndrome of inflammatory disease (Carballo et al., 1998; Taylor et al., 1999). We hypothesized that ovariectomy (OVX) might also prime inflammation by reducing tristetraprolin/zinc finger protein 36 (TTP) levels...

PURPOSE: Oncology training requirements mandate that fellows demonstrate competence in delivery of cancer therapeutics, understand clinical indications for treatment, and manage toxicities by completion of training. An academic training environment may hinder fellows' engagement in prescribing, monitoring, and adjusting cancer therapy; thus, trainees may complete their fellowship with limited experience in developing such critical skills. To provide hands-on experience in cancer systemic therapy management, we created a novel infusion room-based rotation in the final year of training; here we report the structure, logistics, and evaluation of this innovative program...

BACKGROUND: Early-phase trials in patients with recurrent neuroblastoma historically used an objective "response" of measureable disease (Response Evaluation Criteria In Solid Tumors [RECIST], without bone/bone marrow assessment) to select agents for further study. Historical cohorts may be small and potentially biased; to the authors' knowledge, disease recurrence studies from international registries are outdated. Using a large recent cohort of patients with recurrent/refractory neuroblastoma from Children's Oncology Group (COG) modern-era early-phase trials, the authors determined outcome and quantified parameters for designing future studies...

Pancreatic cancer is the fourth leading cause of cancer death in the world. It is a disease of insidious progression and high lethality. The present study was to investigate the diagnostic value of high-filed magnetic resonance (MR) perfusion imaging in pancreatic cancer. Thirty-three patients with suspected pancreatic cancer were recruited in our study and underwent routine MR imaging. When compared with para-tumoral and normal tissue, the pancreatic lesions showed significant lower slope, peak enhancement (PE), and signal enhancement ratio (SER) as well as higher time to peak (TTP)...

BACKGROUND AND OBJECTIVES: Facial paralysis causes excruciating impairments including facial asymmetry, limited eye closure, oral incontinence and social dysfunction. Modern plastic surgical reconstructions render favorable results with well-perfused dynamic muscle flaps. Post-operative tissue monitoring is a critical determinant for success. Contrast-enhanced Ultrasound (CEUS) and elastography have proven superior properties to evaluate tissue perfusion in various organs. We evaluated their role for functional muscle flaps positioned at the sub-skin level in facial palsy patients...

Congenital thrombotic thrombocytopenic purpura (TTP) is a rare hereditary deficiency of ADAMTS13 (von Willebrand factor-cleaving protease) characterized by thrombocytopenia and microangiopathic hemolytic anemia. The spectrum of the clinical phenotype is wide, ranging from asymptomatic episodes of thrombocytopenia to life-threatening multiorgan failure. Reportedly, some patients develop isolated thrombocytopenia during childhood. We herein report sibling cases of congenital TTP. An 11-year-old boy with thrombocytopenia accompanied by influenza virus infection was referred to our hospital...
