Abstract

Cyfra 21-1 is a recognised marker for epidermoid lung and head and neck carcinomas oriented to the cytokeratin 19 that is expressed particularly in malignant epithelial cells. The aims of this study were to evaluate the importance of the use of this marker in nasopharyngeal carcinoma (NPC). Our prospective study interested 41 patients (33M/8F) with a mean age of 44 years (13 to 70) with 8 of them aged less than 30 years, presenting a nasopharyngeal carcinoma histologically confirmed from September 1999 to March 2000 and 45 healthy controls without evidence neoplasm. Undifferentiated forms represent 90.2% of cases and lesions are staged T2, T3 and T4 in 2.4%, 36.6% and 61% of cases, while N1, N2 and N3 represent 9.8%, 26.8% and 41.5% of cases. A blood sample was collected from each patient and control before any treatment, as well as controls to measure Cyfra 21-1 by immunoenzymatic assay, 2 groups of patients were selected after a period varying from 4 to 37 months with a median of 29 months: 27 patients with favourable evolution (without evidence of disease after initial treatment), 12 patients with non favourable evolution (1 death, 2 cases of loco-regional relapse and 9 patients with metastatic disease). 2 patients were lost...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.
