CONTEXT AND OBJECTIVE Fine-needle aspiration biopsy has been accepted worldwide for breast lesions. However, some questions remain, including the appropriateness of the puncture method. The objective of this work was to compare aspirates obtained by the auto-vacuum device and by the syringe pistol holder. DESIGN AND SETTING Randomized trial for validation of diagnostic method, at Hospital das...
In this work, two proteins, Z-domains and bovine casein, were auto-displayed on the outer membrane of the same Escherichia coli cells by co-transformation of two different auto-display vectors. On the basis of SDS-PAGE densitometry, Z-domains and bovine casein were expressed at 3.12 × 10⁵ and 1.55 × 10⁵ proteins/E. coli cell, respectively. The co-auto-displayed Z-domains had antibody-binding ac...
isolated rat hepatocytes in culture were incubated with different concentrations of iron-sorbitol (50, 100, 150, and 200 µm) to assess the changes in reactive oxygen species (ros) and lipid peroxidation leading to apoptotic hepatocyte cell death. the viability of hepatocytes was declined depending on the iron concentration. one hour incubation of the cells with 100 µm iron resulted in decreased...
The recognition that T cell growth factor (TCGF) can maintain T cells in long-term culture offers the opportunity of expanding populations of monoclonal antigen-specific T lymphocytes with helper, suppressor or cytotoxic activity (Fathman & Fitch, 1982). The application of this technology in the generation of tumour reactive T cells for the analysis of tumour antigen recognition and their thera...
introduction: most b-cell malignancies are diagnosed based on morphologic and immunohistochemical criteria. some cases, however, still present a challenge for the pathologist to discriminate between reactive hyperplasia and neoplastic disorders. molecular techniques can be used as a helpful diagnostic tool in these cases. in this study, we assessed the value of polymerase chain reaction (pcr) t...
Direct numerical simulation (DNS) is used to study auto–ignition of turbulent diffusion flames. A novel, all–Mach number algorithm developed by Doom et al is used. The chemical mechanism is a nine species, nineteen reaction mechanism for H2 and Air from Mueller at el. 2 Simulations of three dimensional turbulent diffusion flames are performed. Isotropic turbulence is superimposed on an unstrain...
Bactericidal antibiotics kill by different mechanisms as a result of a specific interaction with their cellular targets. Over the past few years, alternative explanations for cidality have been proposed based on a postulated common pathway, depending on the intracellular production of reactive oxygen species. Detection of hydroxyl radicals relies on staining with specific fluorescent dyes that ...
The relationship between autoimmunity and malaria is not well understood. To determine whether autoimmune responses have a protective role during malaria, we studied the pattern of reactivity to plasmodial antigens of sera from 93 patients with 14 different autoimmune diseases (AID) who were not previously exposed to malaria. Sera from patients with 13 different AID reacted against Plasmodium f...
