Antinuclear antibodies in COVID 19

Antibodies testing, Immunity and immunity passport in Covid-19

The global outbreak of coronavirus disease-2019 (COVID-19) has affected most countries in the world. Our knowledge of diagnostic tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is evolving, and it is important to have a clear understanding of the nature of the tests and the interpretation of their findings. In this paper, the purpose is to interpret the results of two typ...

Antinuclear Antibodies

knowledge of gene regulation, particularly in neoplastic cells, this deficit is striking. With our current understanding of chromosomal translocations, point mutations, and gene amplification in tumor cells, it is surprising to read that there is ". . . no difference between cancer and normal DNA . . ." (p. 130). The author spends a fair amount of time discussing possible mechanisms for the car...

Antinuclear antibodies in rosacea patients

INTRODUCTION Rosacea is a common inflammatory disorder, characterized by a spectrum of facial manifestations. The clinical similarity to other dermatoses, like lupus erythematosus, might lead to misdiagnosis, particularly in patients with elevated antinuclear antibody titers. AIM To assess the frequency, titer and specificity of antinuclear antibodies in rosacea patients and correlate these f...

Antinuclear Antibodies in Rabbit Antisera

Antinuclear antibodies were detected by immunofluorescence in most sera from rabbits immunized with whole human serum emulsified in Freund's complete adjuvant. Four of 14 sera from rabbits immunized with Cohn fractions III, IV-1, or IV-4 also gave positive nuclear fluorescence with human leukocyte nuclei. Other human and animal nuclei gave negative results with these rabbit antisera. Three rabb...
