Abstract

To evaluate the influence of biopsy on cervical intraepithelial neoplasia (CIN). A study was conducted involving 124 women underwent colposcopy-guided biopsy. At the first appointment, the women answered the survey questionnaire, cervical samples were collected for Papanicolaou (Pap) testing and the HPV E6/E7 mRNA test. At the second appointment at three to four months after the first, samples were collected from 81 patients with indications for conization, Pap test, and HPV E6/E7 mRNA testing before they underwent the procedure. PCR was used to detect HPV mRNA. The percentage of negative results before and after the biopsy was evaluated. The agreement between the tests results was evaluated using Cohen's kappa. Sixty-two patients (76.4%) were between 21 and 40 years of age, 35 (43.2%) had four or more pregnancies, 41 (50.5%) had their sexual debut at 16 years of age or more, and 52 patients (64.2%) had undergone five or more Pap tests. The initial biopsy was negative for CIN2/3 in 14 (12.3%) patients; however, all patients were submitted to conization. Among those women with biopsy showing CIN2/3 (66 [81.5%]), 7.41% showed CIN1 and 14.81% were negative in the conization (kappa = 0.2052). The E6/E7 test performed before and aft...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.
