Auditory verbal hallucinations (hearing voices) are typically associated with psychosis, but a minority of the general population also experience them frequently and without distress. Such 'non-clinical' experiences offer a rare and unique opportunity to study hallucinations apart from confounding clinical factors, thus allowing for the identification of symptom-specific mechanisms. Recent theories propose that hallucinations result from an imbalance of prior expectation and sensory information, but whether such an imbalance also influences auditory-perceptual processes remains unknown...

Auditory word comprehension is a cognitive process that involves the transformation of auditory signals into abstract concepts. Traditional lesion-based studies of stroke survivors with aphasia have suggested that neocortical regions adjacent to auditory cortex are primarily responsible for word comprehension. However, recent primary progressive aphasia and normal neurophysiological studies have challenged this concept, suggesting that the left temporal pole is crucial for word comprehension. Due to its vasculature, the temporal pole is not commonly completely lesioned in stroke survivors and this heterogeneity may have prevented its identification in lesion-based studies of auditory comprehension...

Pancreatic cancer (PC) is one of the most common causes of cancer mortality worldwide. As the genetic mechanism of this complex disease is not uncovered clearly, identification of related genes of PC is of great significance that could provide new insights into gene function as well as potential therapy targets. In this study, we performed an integrated network method to discover PC candidate genes based on known PC related genes. Utilizing the subnetwork extraction algorithm with gene co-expression profiles and protein-protein interaction data, we obtained the integrated network comprising of the known PC related genes (denoted as seed genes) and the putative genes (denoted as linker genes)...

We analysed the RNA sequence-based microRNA (miRNA) signature of pancreatic ductal adenocarcinoma (PDAC). Aberrantly expressed miRNAs were successfully identified in this signature. Using the PDAC signature, we focused on 4 clustered miRNAs, miR-216a-5p, miR-216a-3p, miR-216b-5p and miR-216b-3p on human chromosome 2p16.1. All members of the miR-216 cluster were significantly reduced in PDAC specimens. Ectopic expression of these miRNAs suppressed cancer cell aggressiveness, suggesting miR-216 cluster as anti-tumour miRNAs in PDAC cells...

Epstein-Barr virus (EBV) is the pathogenic factor of numerous human tumors, yet certain of its encoded proteins have not been studied. As a first step for functional identification, we presented the construction of a library of expression constructs for most of the EBV encoded proteins and an explicit subcellular localization map of 81 proteins encoded by EBV in mammalian cells. Viral open reading frames were fused with enhanced yellow fluorescent protein (EYFP) tag in eukaryotic expression plasmid then expressed in COS-7 live cells, and protein localizations were observed by fluorescence microscopy...

The most common subtype of renal cell carcinoma (RCC) is clear cell RCC (ccRCC). It accounts for 70-80% of all renal malignancies representing the third most common urological cancer after prostate and bladder cancer. The identification of non-invasive biomarkers for the diagnosis and responsiveness to therapy of ccRCC may represent a relevant step-forward in ccRCC management. The aim of this study is to evaluate whether specific miRNAs deregulated in ccRCC tissues present altered levels also in urine specimens...

Uveitis is a common and etiologically complex disease. The diagnosis of uveitis is mainly based on clinical findings, and no ancillary test is needed for diagnosis of the most common uveitis entities in China. Ancillary tests, however, are needed to identify the underlying cause when the clinical presentation points to some specific disease entity, and when infectious uveitis or masquerade syndrome is suspected. A variety of ophthalmic imaging techniques and laboratory tests analyzing blood or intraocular fluid are currently available for etiological identification in uveitis as well as for disease follow-up...

The anesthesiological management of cerebral emergency represents a great challenge for action under pressure and under time pressure and requires smooth interprofessional cooperation. The exact knowledge of the pathophysiological and pharmacological relationships is the basis for rapid identification of therapeutic influences and possible disturbing factors. In the acute situation, paCO2 and MAP are the central determinants for the anesthetist to ensure cerebral perfusion and the resulting cerebral oxygenation...

The diagnostic evaluation of perioperative anaphylaxia is of great importance for the medical care of the affected persons in the context of renewed interventions in general anesthesia. The most frequent triggers include muscle relaxants, antibiotics, latex and analgesics of the type of the cyclooxygenase inhibitors, but other perioperatively administered drugs such as opioids, anesthetics, benzodiazepines, dyes, disinfectants and even corticosteroids or drug additives may also be the cause in rare cases. The most important aim is therefore the identification of the responsible drug, for which a near-time allergological diagnosis should be carried out within the first 4 weeks to 6 months after the reaction...

Population aging and the concomitant reduction in tooth loss will have a profound effect on dentistry. In particular, an increase in the prevalence of root caries can be expected. Root caries is not evenly distributed across the population and identification of high-risk groups or individuals would facilitate targeted prevention strategies. Unfortunately, the lack of consensus in the literature on the diagnosis and measurement of root caries makes comparison of studies extremely challenging. At present, we do not have an adequately validated risk assessment tool for root caries...

Proteomics data analysis based on the mass-spectrometry technique can provide a powerful tool for early diagnosis of tumors and other diseases. It can be used for exploring the features that reflect the difference between samples from high-throughput mass spectrometry data, which are important for the identification of tumor markers. Proteomics mass spectrometry data have the characteristics of too few samples, too many features and noise interference, which pose a great challenge to traditional machine learning methods...

To determine the stability and influence of adherence barriers on medication adherence and seizure control in pediatric epilepsy. Caregivers of 118 children aged 2-12 years old with epilepsy completed the Pediatric Epilepsy Medication Self-Management Questionnaire at nine time points over 2 years post diagnosis. Electronically monitored antiepileptic drug adherence and seizure outcome data were collected. Hierarchical linear modeling results for overall barriers remained stable over 2 years. Specific item-level barriers were also generally stable over time, with the exception of running out of medication becoming more of a barrier over time...
