Lorenzo Alibardi
The ultrastructural immunolocalization of telomerase and hyaluronate has been studied in a case of oropharyngeal squamous carcinoma. Immunofluorescence shows that telomerase immunolabeling is present in the cytoplasm and in nuclei of some keratinocytes during their migration into the underlying connective tissue. The electron microscope shows that the nuclear localization of telomerase mainly occurs in the large nucleoli and in likely Cajal bodies, the sites of assembling and maturation of proteins forming the telomerase complex...

Primary aneurysmal bone cyst (ABC) is a cystic bone neoplasm characterized by disease-defining gene fusions involving the USP6/Tre2 gene. The literature describing gnathic ABC is limited. This case report describes a 27-year-old man presenting with a long-standing left-sided facial asymmetry. Multi-detector computed tomography imaging demonstrated a large expansile lesion positioned within the left condylar head. The lesion was biopsied and resected. The specimen showed a giant cell-rich cystic neoplasm, with fibrous tissue lined by multinucleated giant cells...

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is a progressive chronic disease leading to obstructive lung airways and airflow limitations. The background of COPD is extensive cytopathology and histopathology orchestrated by mostly chronic inflammation with the local release of inflammatory, anti-inflammatory and regulatory mediators, as well as further remodeling and shaping of local architecture. Inflammatory mechanisms are provided by complex intercellular signalling networks and regulation of locally occurring immune responses...

Genetic screening for BRCA mutations should be offered to all women diagnosed with epithelial ovarian, fallopian tube, and/or peritoneal cancers given the implications for treatment options and cancer risk assessments. Yet, while germline breast cancer susceptibility gene 1 (BRCA1) and breast cancer susceptibility gene 2 (BRCA2) testing is commonly performed, BRCA1/2 somatic mutations testing is rather challenging since the poor quality of DNA extracted from formalin fixed paraffin embedded (FFPE) samples can significantly impair this process...

Apoptosis in intestinal epithelial cells (IECs) promotes the development of ulcerative colitis (UC), a type of inflammatory bowel disease (IBD). Efficient clearance of apoptotic cells is essential for tissue homeostasis in metazoans. Actin related protein 3 (ARP3) promotes endothelial dysfunction. The expression and function of ARP3 in UC remains unclear. In this study, the expression of apoptotic markers as p53, Bax, Cleaved-Caspease9 and Cleaved-Caspease3 were proved to be increased in the intestinal epithelial cells (IECs) of UC patients and in a mouse disuccinimidyl suberate(DSS)-induced colitis model; meanwhile, ARP3 expression was elevated...

Glioma is the commonest malignant tumor in the central nervous system (CNS), characterized by rapid growth. However, the molecular mechanism underlying the growth remains unclear. Immunity-related GTPase family M protein (IRGM) participates in immune response to pathogen and tumorigenesis. Proliferation and autophagy are two crucial functions contributing to aggressive growth. Therefore, our aims were to probe whether IRGM regulates glioma proliferation and autophagy. In this study, we found that 47 glioma specimens had more IRGM expression than 11 non-cancerous brain tissues with immunohistochemistry...

The clinical role and potential molecular mechanisms of microRNA-449c-5p (miR-449c-5p) in hepatocellular carcinoma (HCC) tissues remains unclear. Combining multiple bioinformatic tools, we studied the miR-449c-5p expression levels in HCC tissues and explored possible target genes and related signaling pathways. First, miR-449c-5p expression data from microarrays provided by publicly available sources were mined and analyzed using various meta-analysis methods. Next, genes that were downregulated after miR-449c-5p mimic transfection into HCC cells were identified, and in silico methods were used to predict potential target genes...

BACKGROUND: Assessment of HER2 status is considered standard of care in the histopathologic workup of breast cancer and conveys prognostic and predictive information used to guide treatment decisions. The assessment is often carried out in a two-step approach where immunohistochemical expression of HER2 protein is first evaluated by conventional microscopy and equivocal cases are further analyzed by in-situ hybridization techniques to assess gene amplification status. In this study we compared conventional manual assessment of immunohistochemical HER2 expression with digital image analysis (DIA) and consensus manual assessment by a panel of three pathologists...

This literature review aims to address the main scientific findings on oxidative stress activity in different gestational disorders, as well as the function and application of melatonin in the treatment of fetal and neonatal changes. Oxidative stress has been associated with the etiopathogenesis of recurrent miscarriages, preeclampsia, intrauterine growth restriction, and stillbirth. Both, the exacerbated consumption of the antioxidant enzymes superoxide dismutase, catalase and glutathione peroxidase, and the increased synthesis of reactive oxygen species, such as superoxide, peroxynitrite, and hydrogen peroxide, induce phospholipid peroxidation and endothelial dysfunction, impaired invasion and death of trophoblast cells, impaired decidualization, and remodeling of maternal spiral arteries...
