Abstract

To evaluate the effect of human papillomavirus (HPV) L1 capsid protein detection in cervical exfoliated cells as a proper triage for women with high-risk human papillomavirus (hrHPV) genotypes other than HPV 16/18. From January 2013 to June 2015, a total of 513 women aged 30-65 years infected with non-16/18 hrHPV were enrolled into the study. Primary HPV testing, HPV 16/18 genotyping and Papanicolaou (Pap) test were performed in all eligible women. HPV L1 capsid protein was detected by immunocytochemistry in cervical exfoliated cells. All hrHPV positive women underwent colposcopy and further biopsy if indicated. Relationships between HPV L1 capsid protein expression and histologic diagnosis, as well as cytology were analyzed. The positive expression rate of HPV L1 capsid protein in CIN2+ group was significantly lower than that in CIN1 or better group (16.3% vs. 66.7%, P=0.000). Compared with the Pap test, HPV L1 detection achieved higher sensitivity (83.7% vs. 51.2%, P=0.000), higher negative predictive value (NPV) (95.3% vs. 88.6%, P=0.002), and significant lower specificity (66.7% vs.76.1%, P=0.002) while identifying CIN2+. Compared with the Pap test, HPV L1 detection achieved higher sensitivity (89.7% vs. 51.7%, P=0.008), 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.
