BACKGROUND: During observation of the Necker cube perception becomes unstable and alternates repeatedly between a from-above-perspective ("fap") and a from-below-perspective ("fbp") interpretation. Both interpretations are physically equally plausible, however, observers usually show an a priori top-down bias in favor of the fap interpretation. Patients with Autism spectrum disorder are known to show an altered pattern of perception with a focus on sensory details. In the present study we tested whether this altered perceptual processing affects their reversal dynamics and reduces the perceptual bias during Necker cube observation...

Cribriform morular variant of PTC (CMV-PTC) frequently shows activation of the CTNNB1/Wnt pathway with nuclear accumulation of beta catenin. The utility of LEF-1, also in the CTNNB1/WNT pathway, in the diagnosis of CMV-PTC has not been previously studied. LEF-1 immunohistochemistry was performed on seven CMV-PTC, 52 benign cases and 101 malignant thyroid neoplasms. LEF-1 was scored by stain intensity (0 = no nuclear stain, 1 = weak nuclear stain, less than lymphocyte and 2 = strong nuclear stain, intense as lymphocyte) and percentage of positive cells at each intensity, for a maximum total score of 200...

<p>Reconstruction of defects of the lower lip can be very challenging. The aim of this review is to analyze the unique characteristics of lower lip anatomy and provide a systematic approach for lower lip reconstruction. A review of current literature was performed using the PubMed database. Articles analyzing the anatomic and histologic characteristics of the lower lip, mechanics of local faps, and different lower lip recon-struction techniques were included. Articles focused on lower lip reconstruction with free faps were excluded...

BACKGROUND: Familial adenomatous polyposis (FAP) is a rare, autosomal dominant disease clinically characterized by the early onset of many adenomatous polyps throughout the colon, which turn into colon cancer, if left untreated. In FAP patients, polyps can also occur in the upper gastrointestinal (GI) tract, especially in the duodenum. Adenomas beyond duodenum are rare and mostly located in the proximal jejunum and distal ileum. The management of such polyps can be either surgical or endoscopic, depending on the features of the polyp, Spigelman stage and patient's clinical conditions...

Objective To estimate the global prevalence of transthyretin familial amyloid polyneuropathy (ATTR-FAP). METHODS: Prevalence estimates and information supporting prevalence calculations was extracted from records yielded by reference-databases searches (2005-2016), conference proceedings, and non-peer reviewed sources. Prevalence was calculated as prevalence rate multiplied by general-population size, then extrapolated to countries without prevalence estimates but with reported cases...

Therapeutic strategies aiming for the induction of an effective immune response at the tumor site can be severely hampered by the encounter of an immunosuppressive microenvironment. We investigated here the potential of concerted costimulation by tumor-directed antibody-fusion proteins with B7.1, 4-1BBL and OX40L to enforce bispecific antibody-induced T cell stimulation in presence of recognized immunosuppressive factors including IL-10, TGF-β, indoleamine 2,3-dioxygenase (IDO), PD-L1 and regulatory T cells...

We report a case of double domino liver transplantation in a 32-year-old woman who was diagnosed with familial amyloid polyneuropathy (FAP) and liver dysfunction. A two-stage surgical plan was designed, and one domino graft was implanted during each stage. During the first stage, an auxiliary domino liver transplantation was conducted using a domino graft from a 4-year-old female child with Wilson's disease. After removing the right lobe of the FAP patient's liver, the graft was rotated 90 degrees counterclockwise and placed along the right side of the inferior vena cava (IVC)...

Fibroblast activation protein-α (FAP-α) is a cell surface serine protease of the post-prolyl peptidase family, and stromal FAP-α expression may serve important functions in tumor occurrence and progression. In recent years, FAP-α expression in tumor cells has been detected in a number of types of tumor, and its roles in tumor growth and metastasis have been reported. However, the presence of FAP-α in colorectal cancer (CRC) cells lacks sufficient evidence and its role in angiogenesis remains unknown. The present study confirmed FAP-α expression in CRC cells at the tissue and cellular level, using immunohistochemistry and western blot analysis, respectively; it additionally identified that FAP-α in CRC cells was positively associated with vascular endothelial growth factor (VEGF)-A expression and microvessel density in stained tissue samples for the first time...

Familial adenomatous polyposis (FAP) is a genetic disorder characterized by the development of hundreds of polyps throughout the colon. Without prophylactic colectomy, most individuals with FAP develop colorectal cancer at an early age. Treatment with eicosapentaenoic acid (EPA) in the free fatty acid form (EPA-FFA) has been shown to reduce polyp burden in FAP patients. Since high-purity EPA-FFA is subject to rapid oxidation, a stable form of EPA compound has been developed in the form of magnesium l-lysinate bis-eicosapentaenoate (TP-252)...

BACKGROUND: The potential to reduce child mortality by preventing folic acid-preventable spina bifida and anencephaly (FAP SBA) is inadequately appreciated. To quantify possible reduction in FAP SBA-associated child mortality in low- and middle-income countries, we conducted an analysis to demonstrate in India, a country with more than 25 million births and 1.2 million under-five deaths each year, the decrease in neonatal, infant, and under-five mortality that would occur through total prevention of FAP SBA...

The management of duodenal and colorectal tumours is important in patients with familial adenomatous polyposis (FAP). Endoscopic resection (ER) should be carefully performed because the risk of complications during or after (ER) of nonampullary duodenal tumours is higher than that of stomach or colorectal lesions in general. Thus, we evaluated the feasibility of endoscopic resection using bipolar snare (ERB) for nonampullary duodenal tumours in FAP patients. Eleven FAP patients who underwent ERB for nonampullary duodenal tumours at our hospital between October 2013 and December 2016 were retrospectively analysed based on clinicopathological features...

Familial adenomatous polyposis (FAP) is one of the most common hereditary colorectal cancers. Its intestinal and extra-intestinal manifestations are correlated with mutation sties of the APC gene. Potential gene modulation sites in patients who have typical clinical manifestations but with unidentified APC mutations are also discussed, which included MUTYH gene, AXIN gene and certain epigenetic changes. With the generalization of Precision Medicine, to offer individualized treatment and surveillance strategy based on the genotype-phenotype correlation will be of great value for FAP patients...

Background: In addition to the presence of neoplasia in the colon and rectum, patients with familial adenomatous polyposis (FAP) may develop numerous polyps and carcinoma within the upper gastrointestinal tract. Methods: The aim of the present paper was to review the incidence advanced duodenal polyposis or cancer and their surgical outcomes. A retrospective review of patients' records from our department was performed. Information was retrieved from a prospective collected data, including clinical (gender, age, family history), endoscopic [association with colorectal cancer (CRC), polyposis severity, age at diagnosis] and surgical management (age, time from the index surgery, type of procedure, morbidity)...

Gastric cancer and colorectal cancer are two common malignant tumors in digestive tract. 1% to 3% of gastric cancer and 5% to 15% of colorectal cancer are definitely hereditary cancer caused by germline gene mutation. Hereditary gastric cancer includes hereditary diffuse gastric cancer(HDGC) and hereditary intestinal gastric cancer (HIGC). CDH1 gene mutation is the main reason to cause HDGC, so the first degree and the second degree family members of HDGC patients are recommended to receive CDH1 mutation detection, endoscopic examination every year and undergo preventive total gastrectomy...

BACKGROUND: Transanal total mesorectal excision (taTME) is a minimally invasive technique which was developed to overcome the difficulties associated with the "top-down" pelvic dissection by enabling a "bottom-up" dissection in patients with mid- and low rectal cancer. While this technique was primarily designed to manage tumors in the mid- and lower rectum, its spectrum of indications has been broadened to include benign colorectal pathologies. The aim of the present study was to assess our initial experience with taTME in patients undergoing restorative proctocolectomy for familial adenomatous polyposis (FAP)...

BK channels are critical regulators of neuronal activity, controlling firing, neurotransmitter release, cerebellar function, and BK channel mutations have been linked to seizure disorders. Modulation of BK channel gating is well characterized, regulated by accessory subunit interactions, intracellular signaling pathways, and membrane potential. In contrast, the role of intracellular trafficking mechanisms in controlling BK channel function, especially in live cells, has been less studied. Fluorogen-activating peptides (FAPs) are well-suited for trafficking and physiological studies due to the binding of malachite green (MG)-based dyes with sub-nanomolar affinity to the FAP, resulting in bright, photostable, far-red fluorescence...

Inhibitors of the Wingless-related Integration site (WNT)/β-catenin pathway have recently been under consideration as potential chemopreventive agents against Familial Adenomatous Polyposis (FAP). This autosomal-dominant syndrome is caused by germline mutations in the gene coding for the protein APC and leads to hyperactivation of the WNT/β-catenin signaling pathway, uncontrolled intestinal cell proliferation and formation of adenocarcinomas. The aim of the present work was to: (i) test, on in vitro cultures of cells carrying FAP mutations and on ex vivo biopsies of FAP patients, the WNT inhibitory activity of extracts from two common southern Italian apples, Malus pumila Miller cv...
