Abstract

To investigate the relationship between the recurrent spontaneous abortion and soluble human leukocyte antigen (HLA) DQB1 gene polymorphism. Sixty one cases with recurrent spontaneous abortion were included in study group. Of them, 31 were anticardiolipin antibody (ACA) positive, while 30 were negative. Twenty eight cases were with early abortion, 22 were with late abortion, and 11 were with both early and late abortions. Thirty six women without abnormal pregnancy history were recruited as control group. HLA-DQB1 genotyping was carried out by polymerase chain reaction-restrictive fragment length polymorphism (PCR-RFLP). The frequency of DQB1*0201allele in the study group (16.4%, 20/122) was higher than that in the control group (8.3%, 6/72), but the difference was not statistically significant (P > 0.05). The frequency of 57 site with non Asp in the study group was significantly higher than that in the control group (P < 0.05). The frequencies of both DQB1*0201 and *0303 were significantly different among early abortion, late abortion and both early and late abortion groups (P < 0.05 and P < 0.05). The frequency of DQB1*0201 was significantly higher in the early abortion group than that in the late abortion group (P < 0.01). T...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.
