Abstract

Objective: To explore the effects of X-ray repair cross complementing gene 1 (XRCC1) polymorphism and low dose ionizing radiation exposure on radiology professionals' peripheral blood lymphocyte micronucleus. Methods: A matched case-control study was designed. From 2013 to 2015, 1 102 radiology professionals with micronucleus test rusults, and 45 cases with present micronucleus were enroled into case group. 180 diagnostic radiology technicians detecting no micronucleus were chosen as control group, cases and controls were 1∶4 mached on gender, age ≤40 or >40 years old. According to the detection of micronucleus levels (0‰, 1‰, 2‰) , the objects of our study were divided into the reference group, the low detection group and the medium detection group. The form of radiation workers' occupational health examination was used to collect the general baseline of the research objects, history of smoking, drinking, poisonous and harmful material exposure, past medical history, accumulated illuminated dose and lymphocyte micronucleus rates (‰) , etc. Using restriction fragment length polymorphism polymerase chain reaction (RFLP-PCR) technology for genotyping; Compared the baseline data and radiation exposure level between the differentmi...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.
