Shuyan Jiang, Jiaxin Li, Qingshi Zeng, Jiexian Liang
Intimal sarcoma of the pulmonary artery is rare, but false diagnosis of this sarcoma as pulmonary embolism is not infrequent. The present study reports a case of pulmonary artery intimal sarcoma misdiagnosed as pulmonary artery embolism in a 37-year-old female patient. The patient was admitted to the cardiac intensive care unit of Guangdong General Hospital (Guangzhou, China) with the complaint of progressive exertional dyspnea over the past two years. Multi-slice spiral computed tomography, transthoracic echocardiography, right-heart catheterization and cardiac magnetic resonance imaging revealed mimicking severe pulmonary embolism in the pulmonary trunk and right pulmonary artery, with symptoms including chest pain, cough and breathing difficulties...

Nonfunctioning pancreatic neuroendocrine carcinoma (NPNEC) is a poorly differentiated neuroendocrine carcinoma and a rare type of pancreatic cancer. Computed tomography (CT)-based imaging is currently the most effective method for diagnosing and classifying NPNEC. The present study investigated the clinical features and CT manifestations of this disease. The CT manifestations and clinical data of 13 patients with NPNEC, confirmed by surgery or needle biopsy, were retrospectively analyzed. None of the 13 patients exhibited endocrine-related symptoms and a single lesion with a variable position in the pancreatic was observed in all patients...

Esophageal cancer (EC) consists of tumors with a generally poor prognosis, and treatment options for patients with disease recurrence are extremely limited. Due to this poor patient prognosis, the possible treatment toxicity should be carefully balanced against its potential benefit and patient quality of life. Stereotactic body radiotherapy (SBRT) is a rapidly expanding novel technique combining a short treatment time together with high local efficacy and an acceptable toxicity profile. There are no publications thus far presenting data regarding the usage of SBRT utilizing a conventional linear accelerator in locally recurrent EC patients...

Synchronous bilateral breast cancer is rare, and oncocytic carcinoma is an even rarer breast cancer histological subtype. In general, oncocytic tumors are defined as neoplasms with eosinophilic granular cytoplasm and have been reported in various organs. Oncocytic carcinoma of the breast was first documented by Gădăleanu and Craciun in 1987, and 48 cases have since been reported. The present study reports a case of synchronous bilateral breast oncocytic carcinoma. The patient was a 78-year-old woman. Although she exhibited no symptoms, chest computed tomography revealed three multinodular breast tumors: Two in the right breast and one in the left...

Mantle cell lymphoma (MCL) is a mature B-cell non-Hodgkin lymphoma. Patients with MCL generally present with extensive lymphadenopathy and extranodal involvement. To the best of our knowledge, no cases of primary bone MCL with multiple vertebral compression fractures have been reported in the literature thus far. The current study reports the case of a 75-year-old Chinese male patient presenting with lower back pain for 1 year. B symptoms were not observed in the patient's medical history. X-ray revealed osteoporosis, and mixed osteolytic and osteosclerotic lesions in the T10 and L1 vertebrae with decreased height...

Background In end-stage medial osteoarthritis, the surgeon can decide whether to use unicompartmental or total knee arthroplasty for operative treatment of the patient. Despite the available literature there is a lack of evidence to suggest if one procedure can be rated as being superior to the other. With increasing demand for knee arthroplasty, treatment with the highest expectation of success will be of particular interest. The purpose of this manuscript was to analyse and compare the available literature on unicompartmental vs...

An increasingly important issue is the mental strain of professionals in residential care for children and adolescents. However, only few studies investigate mental strain and overload of professionals in an educational context in general and even less in youth welfare institutions. The goal of this study was to examine mental strain experiences of professionals with the "Perceived Stress Questionnaire" (PSQ) in youth welfare institutions, as well as to investigate the relationship between age, duration of employment in this work environment and gender of participants...

We demonstrate a terahertz flat lens based on tri-layer metasurfaces allowing for broadband linear polarization conversion, where the phase can be tuned through a full 2π range by tailoring the geometry of the subwavelength resonators. The lens functionality is realized by arranging these resonators to create a parabolic spatial phase profile. The fabricated 124-μm-thick device is characterized by scanning the beam profile and cross section, showing diffraction-limited focusing and ∼68% overall efficiency at the operating frequency of 400 GHz...

Traditional Chinese Medicine (TCM) has been widely used as a complementary medicine in Acute Myeloid Leukemia (AML) treatment. In this study, we proposed a new classification of Chinese Medicines (CMs) by integrating the latest discoveries in disease molecular mechanisms and traditional medicine theory. We screened out a set of chemical compounds on basis of AML differential expression genes and chemical-protein interactions and then mapped them to Traditional Chinese Medicine Integrated Database. 415 CMs contain those compounds and they were categorized into 8 groups according to the Traditional Chinese Pharmacology...

A high proportion of patients presenting at epilepsy clinics experience functional non-epileptic attacks (FNEA), and while psychological treatment is generally thought to be the required intervention, evidence regarding psychological treatment of FNEA is limited. A small number of psychoeducation treatments have been evaluated, with promising results. As part of routine care within a neuropsychiatry service, a 3-session cognitive-behavior therapy- (CBT-) informed psychoeducation group was developed. Patients with comorbid epilepsy were included...

REVIEW
Edvard Ehler, Daniel Vanek
Isolated populations present a constant threat to the correctness of forensic genetic casework. In this review article we present several examples of how analyzing samples from isolated populations can bias the results of the forensic statistics and analyses. We select our examples from isolated populations from central and southeastern Europe, namely the Valachs and the European Roma. We also provide the reader with general strategies and principles to improve the laboratory practice (best practice) and reporting of samples from supposedly isolated populations...

Vegetable production systems are characterized by intense pesticide use, yet the effects on the surrounding environment are largely unknown and need to be studied. Given this knowledge gap, the objective of this work is to determine the impact of horticulture on a representative watercourse by conducting an integrated study of the occurrence and concentration of pesticides in bottom sediments and their relation to lethal and sublethal effects on benthic fauna. Two sampling campaigns were conducted during seasons of low and high pesticide application in five sites along the Carnaval creek, located in the peri-urban area of La Plata City (Buenos Aires, Argentina)...

Soil organic matter (SOM) is generally treated as a static compartment of soil in pollutant fate studies. However, SOM might be altered or fractionated in soil systems, and the details of SOM property/composition changes when coupled with contaminant behavior are unknown. In this study, a mild acid treatment was adopted to remove reactive minerals and partially remove SOM components. After acid treatment, biomarker signatures showed that lignin-derived phenols were released and black carbon (as suggested by benzene-polycarboxylic acids) and lipids were enriched...

Events of severe air pollution occurred frequently in China recently, thus understanding of the air pollution characteristics and its health risks is very important. In this work, we analyzed a two-year dataset (March 2014 - February 2016) including daily concentrations of six criteria pollutants (PM2.5, PM10, CO, SO2, NO2, and O3) from 18 cities in Henan province. Results reveal the serious air pollution status in Henan province, especially the northern part, and Zhengzhou is the city with the worst air quality...

Non-adjacent dependencies are challenging for the language learning machinery and are acquired later than adjacent dependencies. In this transcranial magnetic stimulation (TMS) study, we show that participants successfully discriminated between grammatical and non-grammatical sequences after having implicitly acquired an artificial language with crossed non-adjacent dependencies. Subsequent to transcranial magnetic stimulation of Broca's region, discrimination was impaired compared to when a language-irrelevant control region (vertex) was stimulated...

A lingering challenge in implementation of ecosystem-based planning is translating high-level conservation objectives to discrete management initiatives. Recent research underscores this, emphasizing the importance of the processes by which plans are developed and how programs to implement plans are delivered to stakeholders. This study contributes to the existing program design, research methodology, and conservation practice literature through an assessment of landowner and conservation practitioner relationships in the Gulf Coastal Plains and Ozarks (GCPO) region of the southern U...

Osnat Harari-Dahan, Amit Bernstein
Re-examining decades of the social construal of Oxytocin, the General Approach-Avoidance Hypothesis of Oxytocin (GAAO) predicts that Oxytocin will modulate responding to emotionally-evocative and personally-relevant social and non-social stimuli due to its action on the neural substrate of approach and avoidance motivation. We report the first critical experimental test of GAAO predictions by means of a double-blind intra-nasal administration of Oxytocin vs. placebo in 90 healthy adults (N=90, 50% women). As predicted, we found that among men and women for whom negative emotion (anxious arousal) is motivationally-relevant, intra-nasal administration of Oxytocin reduced behavioral avoidance of emotionally-evocative negatively-valenced social and non-social stimuli, but not closely matched emotionally-neutral stimuli...

Design of biomaterials for cell-based therapies requires presentation of specific physical and chemical cues to cells, analogous to cues provided by native extracellular matrices (ECM). We previously identified a peptide sequence with high affinity towards apatite (VTKHLNQISQSY, VTK) using phage display. The aims of this study were to identify a human MSC-specific peptide sequence through phage display, combine it with the apatite-specific sequence, and verify the specificity of the combined dual-functioning peptide to both apatite and human bone marrow stromal cells...

BACKGROUND: High rates of depression and anxiety have been consistently reported among patients suffering from chronic pain. Prescription opioids are one of the most common modalities for pharmacological treatment of pain, however in recent years medical marijuana(MM) has been increasingly used for pain control in the US and in several countries worldwide. The aim of this study was to compare levels of depression and anxiety among pain patients receiving prescription opioids and MM. METHODS: Participants were patients suffering from chronic pain treated with prescription opioids (OP,N=474), MM (N=329) or both (OPMM,N=77)...
