Abstract

Calcaneus bone mineral density (BMD) of 7428 Chinese (4126 women, 3302 men; aged 22-94 years) was measured using single-energy X-ray absorptiometry (SXA). A reference range of calcaneus BMD values for healthy Chinese men and women was established and the usefulness of this method for screening and diagnosis in osteoporosis was evaluated. The peak BMD occurred at 20-24 years old and peak BMD in women was significantly lower than in men. BMD loss in the calcaneus started at the age of 35 years for women, and at 63 years in men. BMD loss rate was 1.2%/year for women and 0.56%/year for men after 50 years. The young normal reference for calcaneus BMD was 442.1+/-69.6 mg/cm2 for men and 388.3+/-61.7 mg/cm2 for women calculated from the mean BMD value of subjects whose age ranged from 20 to 49 years. The accumulated BMD loss in the calcaneus is similar to that of Ward's triangle. Multiple linear regression showed that both age and weight were important factors. The incidence of osteoporosis in older men and women (> or = 60 years) is 6.6% and 32.1% respectively. We conclude that calcaneus BMD measurement is useful and sensitive for the screening and diagnosis of osteoporosis. A predictive diagnostic model for osteoporosis based on the...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.
