Abstract

The aim of this work was the study of 88 patients with SLE for clinical, laboratorial and demographical parameters. The patients sera were assayed for the presence of anti-beta-2-microglobulin antibodies by ELISA. These spectrofotometric results were converted in a standard-deviation unity in relation to the average of 29 control individuals values. It was established a cut-off of 2.5 standard-deviation in order to determine the limit of normality as well as the cut-off of 10 standard deviation was chosen in order to defined the higher values. Several statistical significant associations were observed between the anti-beta-2-microgobulin and the clinical and laboratorial parameters. The clinical applications of those associations were determined by the predictive value. It was only considered the values greater then 75%. The negative predictive values found in the lower cut-off were 92% to ANA (homogeneous-peripheral pattern), 89% to high levels CIC, 81% to mucocutaneous vasculitis and 80% to depressed CH50 levels. The positive predictive values found in 88% to high level of mucoprotein, 83% to mucocutaneous vasculitis, 83% to the onset-disease-time lower six years and 78% to limphopenia. Special attention may be paid to the hi...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
