Abstract

To investigate the polymorphisms and evaluate the value in gene diagnosis of four microsatellites, which are the KG8 that locating in 3'untranslated region of PKD1 and SM6, CW4 and CW2, closely linked to PKD1. The DNAs of some unrelated Chinese Han people were analyzed by using PCR, PAGE and silver staining and the findings were compared with those reported on Caucasian. In Chinese, KG8 included 6 alleles and PIC was 0.312; in Caucasian,8 alleles,PIC 0.545. The number of alleles and PIC of KG8 in Chinese were not so many as those in Caucasian. SM6 included 24 kinds of alleles and PIC was 0.80 in Chinese; in Caucasian,16 alleles, PIC 0. 653. CW4 is 9 alleles in Chinese and PIC of SM6 were more than those in Caucasian. In Chinese CW4, 9 alleles, PIC 0.850; in Caucasian, 9 alleles, PIC 0.782. Although the number of CW4 allele in the two nations was the same, PIC in Chinese was higher than that in Caucasian. In Chinese CW2,7 alleles, PIC 0.814; and in Caucasian, 13 alleles, PIC 0.809. The number of allele of CW2 in Chinese was not so many as that in Caucasian; however,the PIC was about the same. The results indicate that there are differences in the number of allele and distribution of the four microsatellite markers between Chines...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.
