Verruciform xanthoma is a rare tumor-like lesion, predominantly affecting the oral mucosa. Although several studies of verruciform xanthoma have been reported, the characteristic features and pathogenesis have not been fully clarified. The purpose of the present study is to perform immunohistochemical analysis using markers of proliferative cell activity and cytokeratins, and to perform compara...

This study evaluated the effect of pasteurization followed by storage under different conditions on the sensory attributes of frozen juçara pulp using quantitative descriptive analysis (QDA). Pasteurization of packed frozen pulp was performed by its immersion in stainless steel tank containing water (80°C) for 5 min, followed by storage under refrigerated and frozen conditions. A trained sensor...

Background: The ovarian tumors with functioning stroma are defined by the morphological presence of endocrine active cells in stroma, and the clinical, biochemical or pathological evidence of endocrine function. Case Report: The ovarian endometrioid adenocarcinoma with functioning stroma accompanied with endometrial endometrioid adenocarcinoma was found in 64-year-old post-menopausal woman comp...

To better understand the origins and modes of transmission of HTLV-3 and to search for other retroviral infections (HTLV-1, HTLV-2, foamy viruses), we studied the family of a HTLV-3-infected individual (Pyl43), from Cameroon. Thirty-five persons were included. All adult men were still actively hunting nonhuman primates (NHP). All women were also butchering and cutting-up animals. Five persons r...

The investigation was conducted to elucidate seasonal histomorphological changes of Leydig cells in Japanese Jungle crows (Corvus macrorhynchos). All adult crows (n=12) were killed for H&E staining. Histologic data of Leydig cells regarding their locations in the interstitium, appearance and disappearance of lipoidal materials in their cytoplasm, precursor cells and fibroblasts are studied. In ...

It is well-known that the morphological variability of mucoepidermoid carcinoma (MEC) of the salivary glands may lead to interpretative difficulties on fine-needle aspiration (FNA) diagnosis. In this study we identify morphologic features that may be useful in the FNA diagnosis of MEC. The cohort included 23 cases of MEC; cytology and histology slides were reviewed and assessed for % cystic com...

This work focuses on reactive extrusion to design polypropylene (PP) chains with long and short branching obtain non-linear behavior for the synthesis of low-density foams (<100 kg m?3) using a batch supercritical carbon dioxide (scCO2) foaming process. From maleic anhydride (MA) grafted PP (PP-g-MA), long-branched are performed [MA]/ [OH] reaction (with Sorbitol alcohol). On other hand, branch...

A mouse model was developed to study the virus-host interaction of molecularly cloned human foamy virus (HFV) in vivo. The infectious process was analysed in two mouse strains, CBA/Ca and C57BL/6J, over a period of 24 weeks by PCR on DNAs from various animal tissues; virus serology was examined by immunoblotting. The infection persisted in both mouse strains and did not induce clinical symptoms...

We show that diffusing-wave spectroscopy can be used as a non-invasive probe of the bulk properties of three-dimensional foams. A new picture accounting for the origin of the temporal fluctuations of multiply scattexd light is developed and corroborated with direct observations through a microscope. Our interpretation and measurements yield the growth law for the coarsening of foam bubbles and ...
