Trisomy 8 in myelodysplastic syndrome (MDS) plays an important role in concurrent intestinal Behçet's disease (BD) pathogenesis. Here, we reported a case of intestinal BD combined with MDS involving trisomy 8. A 48-year-old woman who has had a 20-year history of recurrent oral ulcer, perineal ulcer and iris, was diagnosed as MDS with trisomy 8 four years ago. She developed high fever and acute abdominal pain. Multiple ulcerative perforations in ileum and colon were found by endoscopy, meeting the criteria for intestinal BD...

Fear generalization is a prominent feature of anxiety disorders and post-traumatic stress disorder. It is defined as enhanced fear responding to a stimulus that bears similarities, but is not identical to a threatening stimulus. Pattern separation, a hippocampal-dependent process, is critical for stimulus discrimination; it transforms similar experiences or events into non-overlapping representations. The current study is the first in humans to investigate the extent to which fear generalization relies on behavioral pattern separation abilities...

Proper growth of the pollen tube depends on an elaborate mechanism that integrates several molecular and cytological sub-processes and ensures a cell shape adapted to the transport of gametes. This growth mechanism is controlled by several molecules among which cytoplasmic and apoplastic polyamines. Spermine (Spm) has been correlated with various physiological processes in pollen, including structuring of the cell wall and modulation of protein (mainly cytoskeletal) assembly. In this work, the effects of Spm on the growth of pear pollen tubes were analyzed...

A 49-year-old woman who was asymptomatic was found to have a small liver tumor on abdominal ultrasonography (US) at her annual health checkup. US revealed a hypoechoic, solid, mass measuring 17-mm in size in segment 6. The tumor markers associated with liver malignancy were negative. An infectious disease screen was negative for hepatitis B surface antigen, but positive for antibody to hepatitis B core antigen. Imaging studies using computed tomography (CT), magnetic resonance imaging (MRI), and CT angiography suggested a malignant liver tumor, such as hepatocellular carcinoma...

Lesbian, gay, bisexual, and transgender (LGBT) youth experience disproportionate rates of bullying compared to their heterosexual peers. Schools are well-positioned to address these disparities by creating supportive school climates for LGBT youth, but more research is needed to examine the variety of practices and professional development opportunities put in place to this end. The current study examines how school practices to create supportive LGBT student climate relate to student reports of bullying. Student-level data come from the 2013 Minnesota Student Survey, a state-wide survey of risk and protective factors...

PURPOSE: Chemical exchange saturation transfer (CEST) MRI has shown promise in tissue characterization in diseases like stroke and tumor. However, in vivo CEST imaging such as amide proton transfer (APT) MRI is challenging because of concomitant factors such as direct water saturation, macromolecular magnetization transfer, and nuclear overhauser effect (NOE), which lead to a complex contrast in the commonly used asymmetry analysis (MTRasym). Here, we propose a direct saturation-corrected CEST (DISC-CEST) analysis for simplified decoupling and quantification of in vivo CEST effects...

Recent studies have shown that subcutaneous or subfascial pacemaker- and ICD implantation with continued oral anticoagulation therapy is associated with lower risk for bleeding complications, when compared to heparin bridging strategies. However, ICD generators are often implanted submuscularly. We therefore compared the bleeding risk with continued phenprocoumon therapy vs. heparin bridging in patients receiving submuscular ICD implantation. Between 01/2013 and 12/2013, 104 patients with need for oral anticoagulation received submuscular ICD or CRT-D implantation in our institution...

Notch signaling is an evolutionarily conserved signal transduction pathway that is essential for metazoan development. Upon ligand binding, the Notch intracellular domain (NOTCH ICD) translocates into the nucleus and forms a complex with the transcription factor RBPJ (also known as CBF1 or CSL) to activate expression of Notch target genes. In the absence of a Notch signal, RBPJ acts as a transcriptional repressor. Using a proteomic approach, we identified L3MBTL3 (also known as MBT1) as a novel RBPJ interactor...

Hydrogen sulfide (H2S) exhibits beneficial effects in the cardiovascular system, many of which depend on nitric oxide (NO). Proline-rich tyrosine kinase 2 (PYK2), a redox-sensitive tyrosine kinase, directly phosphorylates and inhibits eNOS. Herein, we investigated the ability of H2S to relieve PYK2-mediated eNOS inhibition and evaluated the importance of the H2S/PYK2/eNOS axis on cardiomyocyte injury in vitro and in vivo. Exposure of H9c2 cardiomyocytes to H2O2 or pharmacological inhibition of H2S production increased PYK2 (Y402) and eNOS (Y656) phosphorylation...

We report an HIV patient aged 38 years with acute inflammatory demyelinating polyradiculoneuropathy subtype of Guillain-Barré syndrome (GBS) as the only manifestation of seroconversion and worsening of GBS being the harbinger of immune reconstitution inflammatory syndrome (IRIS). To date, only 5 cases of GBS during IRIS are reported. They manifested either during the third week or later after starting highly active antiretroviral therapy (HAART). Our patient witnessed worsening weakness by fifth day after starting HAART, even before the occurrence of Pneumocystis jirovecii pneumonia, cautioning one of the impending serious complications of IRIS and helped us initiate steroids at an early date...

Key challenges in providing lifelong antiretroviral therapy (ART) to pregnant and breastfeeding women (Option B+) in sub-Saharan Africa include achieving long-term adherence and retention in care. One intervention that may help address these challenges is mobile text messaging. We evaluated the acceptability of a text messaging intervention to support women's ART adherence and retention in care in rural western Kenya. Forty in-depth interviews with 20 pregnant/postpartum women infected with HIV, their male partners, and four focus groups with 30 health care providers were conducted during September-November 2014...

Dust is a mixture of natural and anthropogenic particles originated from multiple sources, which can represent an hazard for human health. Playgrounds are a site of particularly concern, due to sand dust ingestion by toddlers and inhalation. In this study, 37 sands used in public playgrounds in the city of Barcelona were physico-chemically characterized also in relation to routine maintenance activities such as disinfection and sand renewal. The analyzed sands show a felsic mineralogy dominated by Na-feldspar, quartz, and, to a lesser extent, K-feldspar, with minor amounts of clay minerals, carbonates and hematite...

REVIEW
Iris-Katharina Penner, Friedemann Paul
Fatigue, best described as an overwhelming feeling of tiredness and exhaustion, occurs in the context of various neurological diseases. The high prevalence of fatigue as either a symptom or a comorbidity of neurological disease must be taken seriously, as fatigue interferes with patients' activities of daily living, has a remarkable negative impact on quality of life, and is a major reason for early retirement. The tremendous consequences of fatigue are consistent across neurological diseases, as is the uncertainty concerning its underlying pathophysiological mechanisms...

There is increasing evidence for associations between polymorphisms of the oxytocin receptor (OXTR) gene and autism spectrum disorder, but to date no study has established links with autistic traits in healthy subjects and potential cultural differences. The present research firstly investigated associations between three widely studied OXTR SNPs and autistic and empathic traits (rs53576 (G/A); rs2254298 (G/A); rs2268498 (T/C)) in two independent studies on male and female Caucasian (n = 537) and Chinese students (n = 280)...
