PURPOSE: Apneas occurring during sleep may precipitate autonomic instability in epilepsy patients making them susceptible to sudden death (SUDEP). Literature on heart rate variability (HRV) during apnea among patients with temporal lobe epilepsy (TLE) is sparse. The aim of this study was to characterize the HRV during the peri-apneic period in patients with TLE and compare with HRV of matched healthy individuals during the overnight polysomnographic (PSG) recording. Further, the role of carbamazepine (CBZ) in modulating peri-apneic HRV in the above cohort was also assessed...

The treatment of refractory meningiomas remains a challenge for both neurosurgeons and neuro-oncologists. There have been no clinical reports of the use or effects of anti-PD-1 therapy in patients with meningioma. We describe a patient whose intracranial meningioma decreased significantly in size after treatment with nivolumab, a monoclonal antibody targeting PD-1, for a concomitant advanced lung cancer. This is the first clinical report suggesting that antibodies targeting PD-1 are effective in treating meningioma...

BACKGROUND: High intensity training (HIT) is superior to moderate aerobic training (MAT) for improving quality of life in congestive heart failure (CHF) patients. Speckle tracking echocardiography (STE) has recently been suggested for estimation of left ventricle global and regional function. AIMS: We evaluated the utility of STE for characterizing differences in cardiac function following MAT or HIT in a CHF rat model. METHODS AND RESULTS: Following baseline physiological assessment, CHF was induced by coronary artery ligation in Sprague-Dawley rats...

Discovering the volatile signature of cancer cells is an emerging approach in cancer research, as it may contribute to a fast and simple diagnosis of tumors in vivo and in vitro. One of the main contributors to such a volatile signature is hyperglycolysis, which characterizes the cancerous cell. The metabolic perturbation in cancer cells is known as the Warburg effect; glycolysis is preferred over oxidative phosphorylation (OXPHOS), even in the presence of oxygen. The precise mitochondrial alterations that underlie the increased dependence of cancer cells on aerobic glycolysis for energy generation have remained a mystery...

We describe a droplet microfluidics method to screen for multiple mutations of a same oncogene in a single experiment using passive droplet fusion. Genomic DNA from H1573 cell-line was screened for the presence of the six common mutations of the KRAS oncogene as well as wild-type sequences with a detection efficiency of 98 %. Furthermore, the mutant allelic fraction of the cell-line was also assessed correctly showing that the technique is quantitative.

Von Willebrand factor (vWF) is a glycoprotein with a crucial role in the formation of platelet thrombi, and ADAMTS13 is the main enzyme responsible for vWF cleavage. Both are important in the relationship between diabetic nephropathy, hypercoagulability, and cardiovascular disease. This study evaluated a potential relationship between vitamin D (vitD) levels, vWF, ADAMTS13 activity, and inflammation in diabetic patients on chronic hemodialysis (HD). Blood samples from 52 diabetic patients on chronic HD were obtained to determine vitD levels, vWF, and ADAMTS13 activity, and inflammatory markers...

: Liver cancer, which typically develops on a background of chronic liver inflammation, is now the second leading cause of cancer mortality worldwide. For these patients surgical resection is a principal treatment modality that offers a chance of prolonged survival. However, tumor recurrence after resection, the mechanisms of which remain obscure, markedly limits the long-term survival of these patients. We have previously shown that partial hepatectomy (PH) in Mdr2 knockout (Mdr2(-/-) ) mice, a model of chronic inflammation-associated liver cancer, significantly accelerates hepatocarcinogenesis...

BACKGROUND: Circulating tumor DNA (ctDNA) is an approved noninvasive biomarker to test for the presence of EGFR mutations at diagnosis or recurrence of lung cancer. However, studies evaluating ctDNA as a noninvasive "real-time" biomarker to provide prognostic and predictive information in treatment monitoring have given inconsistent results, mainly due to methodological differences. We have recently validated a next-generation sequencing (NGS) approach to detect ctDNA. Using this new approach, we evaluated the clinical usefulness of ctDNA monitoring in a prospective observational series of patients with non-small cell lung cancer (NSCLC)...

PURPOSE OF THE STUDY Peripheral fractures of the talus (lateral talar process and posterior talar process) are rare injuries, easy to miss on examination due to their location and clinical manifestation. They account for 0.3% to 1.0% of all fractures of the talus. An incorrect or late treatment of talar process fractures can result in permanent pain, impingement syndrome, healing in malposition, pseudoarthrosis development and also, due to joint instability, in a potential development of severe subtalar arthritis...

OBJECTIVES: Patients with epilepsy commonly report excessive daytime sleepiness and daytime fatigue, which may be attributed to the direct effect of seizures, a side effect of antiepileptic drugs or a combination of the two. The aim of the study was to compare sleep profiles in patients with juvenile myoclonic epilepsy (JME) and symptomatic partial epilepsy (PE) in drug naïve and treated patients using standardized sleep questionnaires. METHODS: Three study groups: - 1) juvenile myoclonic epilepsy (N=40) [drug naïve (N=20); On sodium valproate (SVA) (N=20)]; 2) symptomatic partial epilepsy (N=40) [drug naïve (N=20); On carbamazepine (CBZ) (N=20)]; 3) healthy controls (N=40) completed 3 standardized sleep questionnaires - Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, and NIMHANS Comprehensive Sleep Disorders Questionnaire...

RIASSUNTO. Sono sempre più numerose le evidenze degli effetti positivi di interventi ricreativi e terapeutici assistiti dagli animali e rivolti a bambini con Disturbi dello Spettro Autistico (ASD). È stato ipotizzato che l'efficacia di tali interventi derivi dalla capacità degli animali di stimolare aspetti legati alla socialità e alla comunicazione, contrastando quindi il ritiro sociale che caratterizza i soggetti con autismo. In questo articolo viene descritto il caso di un bambino con autismo ad alto funzionamento incluso in un intervento assistito con il cavallo (o riabilitazione equestre) della durata di due anni...

Science is facing a "replication crisis" in which many experimental findings cannot be replicated and are likely to be false. Does this imply that many scientific facts are false as well? To find out, we explore the process by which a claim becomes fact. We model the community's confidence in a claim as a Markov process with successive published results shifting the degree of belief. Publication bias in favor of positive findings influences the distribution of published results. We find that unless a sufficient fraction of negative results are published, false claims frequently can become canonized as fact...

The microRNA miR-504 targets TP53 mRNA encoding the p53 tumor suppressor. miR-504 resides within the fibroblast growth factor 13 (FGF13) gene, which is overexpressed in various cancers. We report that the FGF13 locus, comprising FGF13 and miR-504, is transcriptionally repressed by p53, defining an additional negative feedback loop in the p53 network. Furthermore, we show that FGF13 1A is a nucleolar protein that represses ribosomal RNA transcription and attenuates protein synthesis. Importantly, in cancer cells expressing high levels of FGF13, the depletion of FGF13 elicits increased proteostasis stress, associated with the accumulation of reactive oxygen species and apoptosis...

PURPOSE: Despite recent therapeutic advances, prognosis of patients with pancreatic adenocarcinoma remains poor. Analyses from tumor tissues present limitations; identification of informative marker from blood might be a promising alternative. The aim of this study was to assess the feasibility and the prognostic value of circulating tumor DNA (ctDNA) in pancreatic adenocarcinoma. EXPERIMENTAL DESIGN: From 2011 to 2015, blood samples were prospectively collected from all consecutive patients with pancreatic adenocarcinoma treated in our center...

BACKGROUND: Although significant late tricuspid regurgitation (TR) may develop after surgery for degenerative mitral regurgitation (MR), the use of routine tricuspid annuloplasty is debatable. The study aim was to determine the prevalence and predictors of significant late TR after surgery for degenerative MR. METHODS: A total of 112 patients who had undergone surgery for degenerative MR without concomitant tricuspid valve repair (average follow up 7.7 ± 4.0 years) was studied retrospectively...

INTRODUCTION: Coagulation and fibrinolysis remain sparsely addressed with regards to acute respiratory distress syndrome (ARDS). We hypothesized that ARDS development might be associated with changes in plasma coagulation and fibrinolysis. Our aim was to investigate the relationships between ARDS diagnosis and plasma concentrations of tissue factor (TF), tissue plasminogen activator (t-PA), and plasminogen activator inhibitor-1 (PAI-1) in mechanically ventilated patients at increased risk of developing ARDS...
