Obtaining high cure rates for challenging facial malignancies: A new method for producing rapid, accurate, high-quality frozen sections.
PURPOSE The authors developed a new system to provide rapid, accurate, full-face frozen sections. OBJECTIVE To evaluate the efficacy of the system when applied to the treatment of nonmelanoma cutaneous malignancies using Mohs micrographic surgery (MMS). METHODS Patients undergoing MMS procedures between 2003 and 2007 for nonmelanoma head and neck cutaneous malignancies were prospectively co...

INTRODUCTION This study assessed the microbial quality of clay samples sold on two of the major Ghanaian markets. METHODS The study was a cross-sectional assessing the evaluation of processed clay and effects it has on the nutrition of the consumers in the political capital town of Ghana. The items for the examination was processed clay soil samples. RESULTS Staphylococcus spp and fecal col...
متن کاملThin Sections
Knowledge of the thickness of sections is important for proper interpretation of electron micrographs. Therefore, the thicknesses of sections of n-butyl methacrylate polymer were determined by ellipsometry, and correlated with the color shown in reflected light. The results are: gray, thinner than 60 mmicro; silver, 60 to 90 mmicro; gold, 90 to 150 mmicro; purple, 150 to 190 mmicro; blue, 190 t...
متن کاملA Method of Staining Thin Sections with Lead Hydroxide for Precipitate-free Sections
Staining of thin sections results in greater contrast which facilitates focusing and the observation of fine structure. Lead hydroxide, as suggested by Watson (1), has become increasingly popular as a stain for electron microscopy. However, when lead hydroxide is exposed to the carbon dioxide of air, lead carbonate forms and is deposited on the sections as fine, needle-like crystals, large amor...
متن کاملAnalysis of Thin-Walled Steel Sections Filled with Concrete Using Non-Linear Finite Element Method
Being economical and performing well under cyclic loads, steel sections filled with concrete have been widely used in structural buildings. Extensive studies and experiments have been conducted to investigate the influence of different parameters and loadings on the behavior of these structural components. Based on the data available from previous experiments and studies, this paper discusses t...
