<br>Pancreatic neuroendocrine neoplasias (pNEN) are the most common cause of death in adult patients with multiple endocrine neoplasia type 1 (MEN1). So far, only few chemopreventive strategies (e.g. with somatostatin analogues) have been evaluated for MEN1 associated pNENs. In this experimental study on 75 Men1(+ /T) knockout mice, the effect of aspirin (n=25) and an inhibitor of angiotensin-I converting enzyme (enalapril, n=25) compared to controls (n=25) were evaluated as single chemopreventive strategies for pNENs after 6,9,12,15 and 18 months...

JAK2-V617F-positive chronic myeloproliferative neoplasia (CMN) is marked by dysfunction of integrins and adhesion molecules expressed on platelets, erythrocytes and leukocytes. However, the mechanism by which the two major leukocyte integrin chains, β1 and β2, mediate CMN pathophysiology remained unclear. β1 (α4β1; VLA-4) and β2 (αLβ2; LFA-1) integrins are essential regulators for attachment of leukocytes to endothelial cells. We here show enhanced adhesion of granulocytes from JAK2+/VF knock-in mice to vascular cell adhesion molecule 1 (VCAM1) and intercellular adhesion molecule 1 (ICAM1) coated surfaces...

PURPOSE: Human papillomavirus (HPV) infection in women is known to promote the development of cervical neoplasia. Specific HPV genotypes are more highly associated with disease, and therefore detection and genotyping of HPV infection is critical for preventing and effectively treating cervical cancer. Consequently, various assays using diverse technologies have been developed to detect HPV genotype. Recently the OmniPlex-HPV and GeneFinder HPV methods, based on PCR and Luminex xMAP liquid bead microarray technologies, were developed for the detection of 40 and 32 HPV genotypes, respectively...

Background: Accurate staging of superficial esophageal squamous cell cancer (ESCC) for endoscopic therapy is challenging. Optical coherence tomography (OCT) has been shown to be superior to high-resolution endoscopic ultrasound (EUS). Volumetric Laser Endomicroscopy (VLE), a second-generation OCT, has recently become commercially available. Objective: To assess if VLE can determine which patients with superficial ESSC can undergo endoscopic therapy. Methods: This is a multi-center retrospective study...

Kaposi Sarcoma-associated herpesvirus (KSHV) KSHV induces B cell hyperplasia and neoplasia such as multicentric Castleman's disease (MCD) and primary effusion lymphoma (PEL). To explore KSHV-induced B cell reprogramming in vivo , we expressed the KSHV latency locus, inclusive of all viral miRNAs, in B cells of transgenic mice in the absence of the inhibitory FcγRIIB receptor. The BALB/c strain was chosen as this is the preferred model to study B cell differentiation. The mice developed hyperglobulinemia, plasmacytosis, and B lymphoid hyperplasia...

Menin (MEN1) is a critical modulator of tissue development and maintenance. As such, MEN1 mutations are associated with multiple endocrine neoplasia type 1 (MEN1) syndrome. Although menin is abundantly expressed in the nervous system, little is known with regard to its function in the adult brain. Here, we demonstrate that neuron-specific deletion of Men1 (CcKO) affects dendritic branching and spine formation, resulting in defects in synaptic function, learning, and memory. Furthermore, we find that menin binds to the p35 promoter region to facilitate p35 transcription...

After 8 years, the WHO has now published the updated version of the 4th edition of the classification of hematopoietic and lymphoid tumors. This update provides a conceptual rewrite of existing entities as well as some new provisional entities and categories, particularly among the aggressive B‑cell lymphomas. Important new diagnostic categories include the high-grade B‑cell lymphomas, the large B‑cell lymphoma with IRF4 rearrangement, and the Burkitt-like lymphoma with 11q aberrations. Of particular importance, new concepts concerning the taxonomy and classification of early lymphoid lesions or precursor lesions are included, such as the in situ follicular neoplasia or the in situ mantle cell neoplasia...

INTRODUCTION: The aim was to assess cost-effectiveness of expanding the Swedish HPV-vaccination program to include preadolescent boys, by comparing health-effects and costs of HPV-related disease, with a sex-neutral vaccination program versus only vaccinating girls. METHODS: We used a dynamic compartmental model to simulate the burden of HPV16/18-related disease in Sweden, accounting for indirect effects of vaccination through herd-immunity. The model accounted for sexual behaviour, such as age preferences and men who have sex with men...

BACKGROUND: Human papillomavirus (HPV) vaccination is safe and effective in preventing cervical cancer in females. As HPV infections can also induce cancers of the anus, penis and oral cavity, male vaccination is also advocated, but systematic reviews on efficacy and safety in males are lacking. METHODS: We performed a systematic review on the efficacy, effectiveness and safety of HPV vaccination in males of any age. MEDLINE, Embase, the Cochrane Central Register of Controlled Trials and ClinicalTrials...

Pancreatic cancer is the third leading cause of cancer deaths in the United States with more than 53,000 expected to be diagnosed with the disease in 2018. The median survival time after diagnosis is four to six months. The poor survival statistics are due in part to the fact that pancreatic cancer is typically asymptomatic until it reaches advanced stages of the disease. Although surgical resection provides the best chance of survival, pancreatic cancer is rarely detected when surgery is still possible due, in part, to lack of effective biomarkers for early detection...
