The spatial organization of proteins in a cell population or in tissues is an important parameter to study the functionality of biological specimens. In this article, we have focused on tight junctions which form network-like features in immunofluorescence microscopy images. Usually, the organization or disorganization of tight junctions is noticed(More)
OBJECTIVE To assess the etiological role and the clinical characteristics of HRV and HEV infections in pediatric patients hospitalized for acute respiratory tract infections (ARTIs). METHODS RT-qPCR assays and molecular sequencing methods were used to identify HRV and HEV strains in nasopharyngeal aspirates of 309 hospitalized pediatric patients with(More)
Upon chronological aging, human skin undergoes structural and molecular modifications, especially at the level of type I collagen. This macromolecule is one of the main dermal structural proteins and presents several age-related alterations. It exhibits a triple helical structure and assembles itself to form fibrils and fibers. In addition, water plays an(More)
The differential diagnosis between meningioma and others tumors can be challenging. This study aimed to evaluate different immunohistochemical markers for the differential diagnosis between meningioma and their morphological mimics. Immunohistochemistry was performed on tissue microarray with antiepithelial membrane antigen (EMA), progesterone receptor,(More)
Emphysema is the major component of chronic obstructive pulmonary disease (COPD). During emphysema, elastin breakdown in the lung tissue originates from the release of large amounts of elastase by inflammatory cells. Elevated levels of elastin-derived peptides (EP) reflect massive pulmonary elastin breakdown in COPD patients. Only the EP containing the(More)
Medical research projects become increasingly dependent on biobanked tissue of high quality because the reliability of gene expression is affected by the quality of extracted RNA. Hence, the present study aimed to determine if clinical, surgical, histological, and molecular parameters influence RNA quality of normal and tumoral frozen colonic tissues. RNA(More)
Thrombospondin-1 (TSP-1) is a matricellular glycoprotein known for being highly expressed within a tumor microenvironment, where it promotes an aggressive phenotype particularly by interacting with the CD47 cell-surface receptor. While it originates from the stromal compartment in many malignancies, melanoma is an exception as invasive and metastatic(More)
