Neurocognitive dysfunction is an important feature of Cushing's syndrome (CS). Our hypothesis was that patients with CS in remission have decreased functional brain responses in the prefrontal cortex and hippocampus during memory testing. In this cross-sectional study we included 19 women previously treated for CS and 19 controls matched for age, gender, and education. The median remission time was 7 (IQR 6-10) years. Brain activity was studied with functional magnetic resonance imaging during episodic- and working-memory tasks...

This is a rare presentation of a morbidly obese male with a massive retropharyngeal goiter causing laryngeal compressive symptoms and unique airway management challenges. Flexible laryngoscopy revealed a retropharyngeal mass circumferentially compressing the oropharynx and supraglottis and preventing the visualization of the glottis. Awake tracheostomy was performed before total thyroidectomy. Airway compression from a goiter typically results from substernal extension, which usually does not cause difficulty with endotracheal intubation...

This study investigates suicide and overdoses in 1119 consecutive patients (64% women), 15 to 34 years of age, presenting at the emergency department after self-poisoning from1994 to 2000 and followed regarding death up to 2006. Regression and Kaplan-Meier survival analyses were performed for suicide and other causes of death. The patients had about a 60 times higher risk (SMR = 61.95) of death due to suicide and 26 times higher (SMR = 26.47) for all-cause mortality. Men had a nearly two times higher risk for suicide than women and half of the suicides occurred during the first two years after admission...

PURPOSE: Granulomatosis with polyangiitis (GPA) is a multisystem disease, characterized by necrotizing small-vessel vasculitis, which mainly affects the respiratory tract and the kidneys. Pituitary involvement in GPA is rare, present in about 1% of all cases of GPA. To date, only case reports or small case series have been published. Herein we report clinical features, imaging findings, treatment and outcomes in three patients with GPA-related pituitary dysfunction (PD). METHODS: A retrospective analysis of three cases of GPA-related PD was conducted, followed by systematic review of the English medical literature using PubMed...

Angiopoietins are a family of growth factors that are ligands for the tyrosine kinase receptor, Tie2. Angiopoietin 1 (Ang-1) is agonistic for Tie2, plays a key role in blood vessel maturation and stability and has been shown to possess anti-inflammatory properties. However, Tie2 expression has been demonstrated on human neutrophils and the observation that neutrophils migrate in response to Ang-1 in vitro has confounded research into its exact role in inflammation as well as its potential use as a therapeutic agent...

Sugarcane smut is a fungal disease caused by Sporisorium scitamineum, which can cause severe economic losses in sugarcane industry. The infection depends on the mating of bipolar sporida to form a dikaryon and develops into hyphae to penetrate the meristematic tissue of sugarcane. In this study, we set to isolate bacterial strains capable of blocking the fungal mating and evaluate their potential in control of sugarcane smut disease. A bacterial isolate ST4 from rhizosphere displayed potent inhibitory activity against the mating of S...

Leptospirosis is a common life-threatening disease worldwide. However, its diagnosis is frequently ineffective because the gold standard bacterial culture and microscopic agglutination test (MAT) are usually positive 1-2 weeks after the disease onset. We thus developed an immunochromatographic assay (LEPkit) to detect serum anti-leptospiral lipopolysaccharide (LPS) IgM for rapid diagnosis of acute leptospirosis. Using referenced sera of 77 leptospirosis and 91 non-leptospirosis cases, LEPkit yielded 97.4% sensitivity, 94...

INTRODUCTION: Large cell carcinoma with or without neuroendocrine features (LCNEC and LC, respectively) constitutes a small proportion of non-small cell lung cancer (NSCLC). The WHO2015 classification guidelines changed the definition of the debated histological subtype LC to be based on immunomarkers for adenocarcinoma and squamous cancer. We sought to determine if these new guidelines translate also to the transcriptional landscape of lung cancer, and LC specifically. METHODS: Gene expression profiling was performed using Illumina V4 HT12 microarrays on 159 cases (comprising all histological subtypes including 10 WHO2015 LC and 14 LCNEC tumors), with complimentary mutational and IHC data...

The management of non-muscle-invasive bladder cancer (NMIBC) has evolved from the first reports on bladder endoscopy and transurethral resection to the introduction of adjuvant intravesical treatment. However, disease recurrence and progression remain an ongoing risk, placing a heavy burden on healthcare resources and on patients' quality of life. Deeper understanding of the molecular basis of the disease and developments in optics, lasers and computer science are already offering opportunities to revolutionize care and improve long-term prognosis...

For the enhancement of protein's bioavailability, a specific delivery system was developed by coaxial electrospinning. Bovine serum albumin (BSA) was used as protein model and the core-sheath fiber mat was fabricated using sodium alginate as shell layer and the BSA-loaded chitosan nanoparticle that prepared previously as core layer. By optimizing electrospinning parameters, uniform fibers with diameters ranging from 200 nm to 600 nm were obtained, and transmission electron microscopy and confocal laser scanning microscopy revealed its core-sheath structure...

RATIONALE: Despite the importance of dynamic changes in the regional distributions of gas and blood during the breathing cycle for lung function in the mechanically ventilated patient, no quantitative data on such cyclic changes is currently available. METHODS: We used a novel gated synchrotron CT-imaging to quantitatively image regional lung gas (Vg), tissue density and blood volume (Vb) in 6 anaesthetized, paralyzed and mechanically ventilated rabbits with normal lungs...

The coordination of CO to metalloporphyrins changes their electronic and magnetic properties. Here we locally desorb CO molecules from a single ruthenium tetraphenylporphyrin carbonyl (CO-RuTPP) on Cu(110) using STM. The desorption is triggered by the injection of holes into the occupied states of the adsorbate using an unusual two-carrier process.

Unlike with zinc finger nuclease and transcriptional activator-like effector nuclease DNA modification technologies that rely on lead proteins, developed through expensive and time-consuming processes, the clustered regularly interspaced short palindromic repeat (CRISPR)/Cas system has rapidly emerged as the most promising gene-editing technology to date for the modification of any selected DNA sequence. CRISPR is receiving tremendous fanfare due, in part, to its potential to provide a means to fundamentally alter medical genetics and especially cancer medicine...

The tissue microenvironment has profound effects on tissue-specific regeneration. The 3-dimensional extracellular matrix (ECM) niche influences the linage-specific differentiation of stem cells in tissue. To understand how ECM guides tissue-specific regeneration, we established a series of 3D composite scaffolds containing ECMs derived from different primary cells isolated from a single animal species and assessed their impact on the differentiation of human mesenchymal stem cells (hMSCs). Synthetic microfiber scaffolds (fiber mats) were fabricated by electrospinning tyrosine-derived polycarbonates (pDTEC)...

Little is known about large sulfur bacteria (LSB) that inhabit sulfidic groundwater seeps in large lakes. To examine how geochemically relevant microbial metabolisms are partitioned among community members, we conducted metagenomic analysis of a chemosynthetic microbial mat in the Isolated Sinkhole, which is in a deep, aphotic environment of Lake Huron. For comparison, we also analyzed a white mat in an artesian fountain that is fed by groundwater similar to Isolated Sinkhole, but that sits in shallow water and is exposed to sunlight...

Throughout human evolution, infectious diseases have been a primary cause of death. Detection of subtle cues indicating sickness and avoidance of sick conspecifics would therefore be an adaptive way of coping with an environment fraught with pathogens. This study determines how humans perceive and integrate early cues of sickness in conspecifics sampled just hours after the induction of immune system activation, and the underlying neural mechanisms for this detection. In a double-blind placebo-controlled crossover design, the immune system in 22 sample donors was transiently activated with an endotoxin injection [lipopolysaccharide (LPS)]...

Leptospirosis is an important worldwide zoonosis. While human leptospirosis remains rare in Switzerland, the incidence of canine leptospirosis is unusually high compared to other European countries. The aims of this cross-sectional study were to determine the exposure of asymtomatic dogs to pathogenic Leptospira in Switzerland, to characterise risk factors associated with seropositivity and to determine the prevalence of urinary shedding. Sampling was stratified to cover the whole of Switzerland. Sera were tested by microscopic agglutination test for antibodies against a panel of 12 serovars...
