BACKGROUND: Primary pulmonary artery sarcoma (PPAS) is a rare tumor that mimics pulmonary thromboembolism (PE). Similarities to PE can delay the diagnosis and misguide the treatment of PPAS. This study aimed to evaluate tumor characteristics and outcome predictors among those diagnosed with PPAS and misdiagnosed as PE. METHODS: From 1991-2010, 10 PPAS cases were available from the Cleveland Clinic (CC) institutional database and another 381 cases were reported in the literature...

Systems biology models are rapidly increasing in complexity, size and numbers. When building large models, researchers rely on software tools for the retrieval, comparison, combination and merging of models, as well as for version control. These tools need to be able to quantify the differences and similarities between computational models. However, depending on the specific application, the notion of 'similarity' may greatly vary. A general notion of model similarity, applicable to various types of models, is still missing...

BACKGROUND: Preterm infants start milk feeds by gavage tube. As they mature, sucking feeds are gradually introduced. Women who choose to breast feed their preterm infant are not always able to be in hospital with their baby and need an alternative approach to feeding. Most commonly, milk (expressed breast milk or formula) is given by bottle. Whether using bottles during establishment of breast feeds is detrimental to breast feeding success is a topic of ongoing debate. OBJECTIVES: To identify the effects of avoidance of bottle feeds during establishment of breast feeding on the likelihood of successful breast feeding, and to assess the safety of alternatives to bottle feeds...

Uroplakin II antibody is exclusively specific for urothelial carcinoma. Nonurothelial carcinoma has not been reported to be immunoreactive for uroplakin II. In the present study, we hypothesized that breast carcinoma showing apocrine differentiation, such as invasive pleomorphic lobular carcinoma (IPLC) and apocrine carcinoma (AC), stains positive for uroplakin II. We identified 6 cases of IPLC between 2000 and 2014 by searching a computerized pathological database. We randomly selected 10 cases of each classic invasive lobular carcinoma (cILC) and AC and five cases of apocrine metaplasia (AM) that coexisted in a surgically resected breast carcinoma specimen...

Anaplastic thyroid carcinoma (ATC) originates from completely undifferentiated cells, and is the most lethal type of thyroid-derived tumor. Numerous microRNAs have significant roles in tumorigenesis by targeting relevant genes. The role of microRNA 146b (miR-146b) in ATC remains to be elucidated. In order to characterize the role of miR-146b in ATC, overexpression or interference of miR-146b was induced in ATC cell lines, and cell proliferation and migration were evaluated. The potential targets of miR-146b were searched in the Gene Expression Omnibus database for ATC and matched non-tumor control samples...

BACKGROUND: To develop a set of transcriptome sequences to support research on environmental stress responses in green ash (Fraxinus pennsylvanica), we undertook deep RNA sequencing of green ash tissues under various stress treatments. The treatments, including emerald ash borer (EAB) feeding, heat, drought, cold and ozone, were selected to mimic the increasing threats of climate change and invasive pests faced by green ash across its native habitat. RESULTS: We report the generation and assembly of RNA sequences from 55 green ash samples into 107,611 putative unique transcripts (PUTs)...

We introduce and validate a beat-to-beat optical blood pressure (BP) estimation paradigm using only photoplethysmogram (PPG) signal from finger tips. The scheme determines subject-specific contribution to PPG signal and removes most of its influence by proper normalization. Key features such as amplitudes and phases of cardiac components were extracted by a fast Fourier transform and were used to train an artificial neural network, which was then used to estimate BP from PPG. Validation was done on 69 patients from the MIMIC II database plus 23 volunteers...

BACKGROUND: Alemtuzumab is a humanized monoclonal antibody directed against CD52, a cell surface antigen on B and T lymphocytes, and used to treat B-cell chronic lymphocytic leukemia and cutaneous T-cell lymphoma. Skin rash is a common adverse reaction following treatment with alemtuzumab. However, the clinicopathologic features and immunologic basis for the reaction have not been previously reported. METHODS: Our hospital's electronic pathology database was searched for cases with documentation of "alemtuzumab" or "anti-CD52" in the clinical history provided by either the ordering physician or the pathologist...

One of the most common psychiatric diagnoses among adolescents is anxiety disorder. Many of the anxiety symptoms are expressed physiologically, and therefore can mimic other medical conditions. The aim of this study was to examine the association between anxiety disorders and other medical conditions sharing common symptoms with anxiety (MDSCSA: Irritable Bowel Syndrome, asthma, migraine and hyperhidrosis). The study was based on the national database of the candidates for military service in Israel. Data for the years 1998-2013 was retrieved to create the study dataset...

BACKGROUND AND OBJECTIVES: Lymphoepithelial cysts (LECs) of the pancreas are benign lesions that can mimic cystic neoplasms on imaging. Endoscopic ultrasound (EUS) features have not been well described. We aimed to describe the clinical and EUS characteristics of LECs and the present outcomes of management at a high-volume referral center. MATERIALS AND METHODS: We identified patients who underwent EUS and were found to have LECs based on fine-needle aspiration (FNA) cytology or surgical pathology from existing databases...

Microneurotrophins (MNT's) are small molecule derivatives of dehydroepiandrosterone (DHEA) and do not have significant interactions with sex steroid receptors. MNT's retain high-affinity binding to protein tyrosine kinase (Trk) receptors and can mimic many pleiotropic actions of neurotrophin (NT) proteins on neurons. MNT's offer therapeutic potential for diseases such as amyotrophic lateral sclerosis (ALS) where motor neurons (MN) degenerate. MNT's cross artificial membranes mimicking the blood-brain barrier, are not major substrates for ABC (ATP-binding cassette) transporters and are metabolized rapidly by mouse but more slowly by human hepatocytes...

BACKGROUND: The presence of Alcohol Use Disorder (AUD) complicates the medical conditions of patients and increases the difficulty of detecting and predicting the onset of septic shock for patients in the ICU. METHODS: We have developed a high-performance sepsis prediction algorithm, InSight, which outperforms existing methods for AUD patient populations. InSight analyses a combination of singlets, doublets, and triplets of clinical measurements over time to generate a septic shock risk score...

Retinoic acid inducible gene I (RIG-I) can recognize influenza viruses and evoke the innate immune response. RIG-I is absent in the chicken genome, but is conserved in the genome of ducks. Lack of RIG-I renders chickens more susceptible to avian influenza infection, and the clinical symptoms are more prominent than in other poultry. It is unknown whether introduction of duck RIG-I into chicken cells can establish the immunity as is seen in ducks and the role of RIG-I in established immunity is unknown. In this study, a chicken cell strain with stable expression of duRIG-I was established by lentiviral infection, giving DF1/LV5-RIG-I, and a control strain DF1/LV5 was established in parallel...

OBJECTIVE: In this paper we propose a novel application of reinforcement learning to the area of auditory neural stimulation. We aim to develop a simulation environment which is based off real neurological responses to auditory and electrical stimulation in the cochlear nucleus (CN) and inferior colliculus (IC) of an animal model. Using this simulator we implement closed loop reinforcement learning algorithms to determine which methods are most effective at learning effective acoustic neural stimulation strategies...

MicroRNAs (miRNAs) negatively regulate the expression of the target genes by binding to 'seed sequences' in the 3'‑untranslated region (3'‑UTR) mRNA transcripts, and the variants within or nearby 'seed sequences' may compromise or enhance miRNA/mRNA interaction leading to either 'loss‑of‑function' or 'gain‑of‑function' effects. Cataracts are the leading cause of blindness worldwide and are characterized by progressive aggregation and precipitation of lens proteins, and the development of age‑related cataracts is associated with dysregulated cellular activities of lens epithelial cells...

BACKGROUND: Despite great advancement in treatment of sepsis, mortality of sepsis remains unacceptably high, even with the modern antibiotic and intensive care technologies. Considering the key role of immune dysfunction in sepsis pathophysiology, different treatments were evaluated, but failed to improve survival of patients. Natural remedies have been tested in various studies to overcome sepsis. In this study, we aim to review some of the evidence from clinical, in vitro and in vivo studies about the effect of alternative medicine on sepsis management...
