PURPOSE: The AMPK-activator AICAR recently raised great interest for its anti-cancer properties. With specific regard to thyroid cancer, AICAR reduces cancer cell growth, invasion and metastasis. CXCL8, a chemokine with several recognized tumorigenic effects, is abundantly secreted in thyroid cancer microenvironment. The aim of this study was to investigate if AICAR could inhibit the basal and the TNFα-induced CXCL8 secretion in normal human thyroid cells (NHT) and in thyroid cancer cell lines TPC-1 and BCPAP (RET/PTC and BRAFV600e mutated, respectively)...

AIMS: The presence of cold agglutinin in blood samples can cause a spontaneous agglutination of red blood cells (RBCs) when low temperature occurs. This phenomenon causes a spurious lowering of RBC count on the automated haematological analysers that are detected by incongruous values (≥370 g/L) of the mean cellular haemoglobi concentration (MCHC). A preheating at 37°C can remove the RBC agglutination generally resulting in a reliable count. It has been reported that the same result can be reached by using the optical reticulocyte (RET) channel of Sysmex analysers where the RBC count is not influenced by the presence of cold agglutinin...

Medullary thyroid carcinoma (MTC) is a neuroendocrine tumor hereditary in 35% of cases. The most common syndromic form is in the context of the multiple endocrine neoplasia type 2 (MEN 2) syndromes in association with other tumors and due to germline RET mutations. We describe a 57-year-old female patient diagnosed with sporadic MTC. The patient had a history of other neoplasias, such as acute myeloid leukemia, for which she had received chemotherapy, and two other solid tumors, peritoneal mesothelioma and meningioma...

Purpose: Medullary Thyroid Cancer (MTC) whose pathogenesis is strictly related to RET proto-oncogene alterations, has been shown to have a heterogenic RET mutation profile in subpopulations of MTC. The aim of our study was to investigate the RET somatic mutation profile in primary MTC and in the corresponding metastatic tissues in a series of advanced metastatic cases. Results: This study demonstrated that in about 20% of cases a different RET mutation profile can be found when comparing primary tumor and its corresponding metastases...

Diverse cell types can be reprogrammed into pluripotent stem cells by ectopic expression of Oct4 (Pou5f1), Klf4, Sox3, and Myc. Many of these induced pluripotent stem cells (iPSCs) retain memory, in terms of DNA methylation and histone modifications (epigenetic memory), of their cellular origins, and this may bias subsequent differentiation. Neurons are difficult to reprogram, and there has not been a systematic side-by-side characterization of reprogramming efficiency or epigenetic memory across different neuronal subtypes...

BACKGROUND: Carotid body tumor (CBT) is a form of head and neck paragangliomas (HNPGLs) arising at the bifurcation of carotid arteries. Paragangliomas are commonly associated with germline and somatic mutations involving at least one of more than thirty causative genes. However, the specific functionality of a number of these genes involved in the formation of paragangliomas has not yet been fully investigated. METHODS: Exome library preparation was carried out using Nextera® Rapid Capture Exome Kit (Illumina, USA)...

INTRODUCTION: Medullary thyroid cancer (MTC) is a rare tumour of neuroendocrine origin with a more aggressive profile than differentiated thyroid cancer. Familial cases of MTC are associated with RET mutations whilst RAS mutations appear to be a frequent finding in RET negative tumours. The aims of this study were to analyse survival outcomes in MTC and to evaluate the role of RAS immunohistochemistry in the identification of sporadic disease. MATERIALS AND METHODS: A retrospective cohort study of consecutive patients with MTC was undertaken...

Dipole-bound molecular anions are often envisioned as unperturbed neutral, polar molecules with single excess electrons. Here, we report the observation of intra-molecular structural distortions within silatrane molecules due to the formation of their dipole-bound anions. The combination of Rydberg electron transfer-anion photoelectron spectroscopy (RET-PES) and ab-initio computational methodologies (CCSD and MP2) was used to study 1-hydro- (HS) and 1-fluoro- (FS) silatranes and their dipole bound anions, HS- and FS-...

Regenerative endodontic procedures (REPs) are biologically based procedures planned to replace damaged tissues, including dentinee and root structures, as well as cells of the pulp-dentine complex. Effective sterilization of the root canal is essential in REPs, and antibiotics have been widely used to disinfect root canals. The aim of this paper was to review the scientific literature on 1) Effectiveness of antibiotics used in REPs against bacteria implicated in endodontic disease; 2) Scientific evidence supporting the use of topical antibiotics in REPs; 3) Clinical implications of the use of antibiotics in REPs and the possible side effects; 4) Effect of antibiotics on dental pulp stem cells; and 5) Ongoing research on the use of antibiotics in REPs...
