Abstract

The purpose of this study was to find the frequency distribution ofa SNP rs2297480 of the human FDPS gene and its influences on BMD and bone turnover markers in postmenopausal Thai women who never-use any anti-osteoporotic drugs. One hundred and thirty-five postmenopausal women at the age of 40 or over, and having been menopause for at least 2 years were enrolled in the present study. The patients having chronic medical conditions and having a fracture in any bone within 3 months were excluded. All of the subjects never used any anti-osteoporotic drugs, steroid hormones and warfarin. Bone mineral density and bone turnover markers including N-MID osteocalcin and beta-CTx were performed. Blood samplings for FDPS genotyping were collected and examined for rs2297480 SNP RESULTS: The mean age of the patients was 60.4 (43-79) years old. The mean BMD T-score at all three major sites (Femoral neck, Lumbar spine, and Total hip) fell in the criteria of osteopenia. Twenty-four per cent of patients were diagnosed as osteoporosis (BMD T-score at one of three major sites was equal to or below -2.5 SD). One hundred and thirty-five patients whose data of rs2297480 SNP were defined as follows: AC genotype (45.1%), CC genotype (41.6%) and AA gen...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.
