Bronchial carcinoid tumors (BCTs) represent a subgroup of bronchopulmonary neuroendocrine tumors which have the ability to produce neuropeptides. Merely 2% of BCTs secrete ACTH and less than 1% of patients with Cushing's syndrome (CS) have a BCT. Typical BCTs rarely metastasize. We here present a patient with ectopic CS caused by a typical BCT, which metastasized into a lymph node. This case suggests that the diagnostic work up of CS should be wide and include ectopic ACTH-secreting BCT, and that ACTH secretion can be correlated to a more aggressive type of typical BCTs...

BACKGROUND: Pulmonary metastasectomy (PM) is a standard procedure in the treatment of stage IV colorectal cancer (CRC). In most centers the indication for PM is solely based on clinical factors without taking the tumor biology into account. This results in diverse outcomes ranging from long-term remission to early recurrence. Inflammation is considered a hallmark of cancer development and progression. On the other hand the accessibility of CRC cells to the immune system reflects the grade of tumor aggressiveness...

REVIEW
Meike Vogler, Harriet S Walter, Martin J S Dyer
The B-cell lymphoma 2 (BCL2) family of proteins comprise key regulators of apoptosis and are implicated in the pathogenesis of many malignancies, including lymphomas and leukaemias. Targeting of BCL2 proteins can be directly toxic to tumour cells or render them more sensitive to chemotherapy. Inhibition of the anti-apoptotic functions of BCL2 proteins using structure-based design to produce specific inhibitors of protein-protein interactions has been achieved for BCL2, MCL1 and BCL-XL (also termed BCL2L1), providing an armamentarium of new targeted therapies called BH3-mimetics...

Clinical neurosurgery has been practiced in the US capital for just over 100 years. As former residents and fellows of Drs. Harvey Cushing and Walter Dandy moved to the region, hospitals at Georgetown and George Washington Universities became early adopters of this new surgical discipline. Later academic neurosurgery programs were established at the National Institutes of Health, Walter Reed Medical Center, and Children's National Medical Center. Neurosurgical pioneers at these institutions developed new technologies and diagnostic procedures which continue to inform our current practice...

Background: Higher fruit consumption is associated with lower risk of cardiovascular disease (CVD). Substantial uncertainties remain, however, about the associations of fruit consumption with all-cause mortality and mortality from subtypes of CVD and major non-vascular diseases, especially in China. Methods: In 2004-08, the nationwide China Kadoorie Biobank Study recruited > 0.5 million adults aged 30-79 years from 10 diverse localities in China. Fresh fruit consumption was estimated using an interviewer-administered electronic questionnaire, and mortality data were collected from death registries...

OBJECTIVES: Surgery for thymic epithelial tumours (TETs) with pleural involvement is infrequently performed. Thus, the value of surgical therapy for primary or recurrent TETs with pleural involvement is not sufficiently defined yet. METHODS: Twelve institutions contributed retrospective data on 152 patients undergoing surgery (1977-2014) on behalf of the ESTS Thymic Working group. Outcome measures included overall (OS), cause-specific (CSS) and disease-free (DFS) survival as well as freedom from recurrence (FFR)...

The Sleeping Cupid, by Italian painter Caravaggio is a masterpiece painted in 1608. Signs of an endocrine disease are hidden among the shadows of the painting. We decided to conduct a survey among endocrinologists practicing in Italy and asked them if they could identify a specific disease condition in Caravaggio's Sleeping Cupid. A total of 86 members from two Italian endocrine societies completed the survey, 67 from the Society of Endocrinology and 19 from the Society of Paediatric Endocrinology and Diabetology...

Writing is often used as a tool for learning. However, empirical support for the benefits of writing-to-learn is mixed, likely because the literature conflates diverse activities (e.g., summaries, term papers) under the single umbrella of writing-to-learn. Following recent trends in the writing-to-learn literature, the authors focus on the underlying cognitive processes. They draw on the largely independent writing-to-learn and cognitive psychology learning literatures to identify important cognitive processes...

Mean cell size at division is generally constant for specific conditions and cell types, but the mechanisms coupling cell growth and cell cycle control with cell size regulation are poorly understood in intact tissues. Here we show that the continuously dividing fields of cells within the shoot apical meristem of Arabidopsis show dynamic regulation of mean cell size dependent on developmental stage, genotype and environmental signals. We show cell size at division and cell cycle length is effectively predicted using a two-stage cell cycle model linking cell growth and two sequential cyclin dependent kinase (CDK) activities, and experimental results concur in showing that progression through both G1/S and G2/M is size dependent...

A multifunctional smart supramolecular platform based on a lanthanide-organic hydrogel is presented. This platform, which provides unique biocompatibility and tunable optical properties, is synthesized by a simple, fast and reproducible eco-friendly microwave-assisted route. Photoluminescent properties enable the production of coated light-emitting diodes (LED), unique luminescent barcodes dependent on the excitation wavelength and thin-films for use in tamper seals. Moreover, piroxicam entrapped in hydrogel acts as a transdermal drug release device efficient in inhibiting edemas compared to a commercial reference...

Nitrogen (N) is a key macronutrient representing a limiting factor for plant growth and development and affects productivity in wheat. In this study, durum wheat response to N chronic starvation during grain filling was investigated through a transcriptomic approach in roots, leaves/stems, flag leaf and spikes of cv. Svevo. Nitrogen stress negatively influenced plant height, tillering, flag leaf area, spike and seed traits, and total N content. RNA-seq data revealed 4,626 differentially expressed genes (DEGs)...

Although several different flaviviruses may cause encephalitis, Japanese encephalitis virus is the most significant, being responsible for thousands of deaths each year in Asia. The structural and molecular basis of this encephalitis is not fully understood. Here, we report the cryo-electron microscopy structure of mature Japanese encephalitis virus at near-atomic resolution, which reveals an unusual "hole" on the surface, surrounded by five encephalitic-specific motifs implicated in receptor binding. Glu138 of E, which is highly conserved in encephalitic flaviviruses, maps onto one of these motifs and is essential for binding to neuroblastoma cells, with the E138K mutation abrogating the neurovirulence and neuroinvasiveness of Japanese encephalitis virus in mice...

Rationale: The relative actions and synergism between distinct myocardial-derived stem cell populations remains obscure. Ongoing debates regarding optimal cell population(s) for treatment of heart failure prompted implementation of a protocol for isolation of multiple stem cell populations from a single myocardial tissue sample to develop new insights for achieving myocardial regeneration. Objective: Establish a robust cardiac stem cell isolation and culture protocol to consistently generate three distinct stem cell populations from a single human heart biopsy...

Background Adequate polyp detection is crucial to colonoscopy; however, detection can be impaired. In particular, flat polyps located behind folds or near the colonic flexures appear to be a problem. We present a cheap and easily adjustable 3D-printed tool to enhance the view of a standard colonoscope using additional commercially available sideoptics. Materials and methods A cap adjustable to a standard endoscope was printed by a 3 D printer and had two microcameras fixed to offer two additional views...

Children with neurofibromatosis type 1 (NF1) cancer predisposition syndrome are prone to the development of low-grade brain tumors (gliomas) within the optic pathway (optic gliomas). One of the key obstacles to developing successful therapeutic strategies for these tumors is the striking lack of information about the mechanical properties that characterize these tumors relative to non-neoplastic optic nerve tissue. To study the physical changes that may occur when an optic nerve glioma is present, we employed atomic force microscopy to measure the stiffness of healthy versus tumor-bearing optic nerve tissue...

Human monocytes have been grouped into classical (CD14++CD16-), non-classical (CD14dimCD16++), and intermediate (CD14++CD16+) subsets. Documentation of normal function and variation in this complement of subtypes, particularly their differentiation potential to dendritic cells (DC) or macrophages, remains incomplete. We therefore phenotyped monocytes from peripheral blood of healthy subjects and performed functional studies on high-speed sorted subsets. Subset frequencies were found to be tightly controlled over time and across individuals...
