Abstract

To assess the clinical utility of bone mineral density (BMD) of Ward's triangle by dual-energy absorptiometry (DEXA) as an indicator of osteoporosis in comparison with quantitative computed tomography (QCT) of the lumbar spine and DEXA of the lumbar spine and hip sites (trochanter and femoral neck). We conducted a retrospective study of all patients (28 men and 17 women) with decreased BMD by QCT (T-score less than -1.0) who had DEXA BMD performed at the lumbar spine and hip between October 1993 and January 1995 in our Endocrine Clinic. Osteoporosis based on the World Health Organization criteria (T-score less than -2.5) was defined by QCT lumbar spine BMD in 78% of the study subjects and by DEXA of Ward's triangle in 53%, of the femoral neck in 22%, of the trochanter in 7%, and of the lumbar spine in 2%. In the men, the only DEXA BMD measurement that was sensitive for detecting osteoporosis was Ward's triangle. Of the 24 men with osteoporosis by QCT BMD, 14 were defined as having osteoporosis by DEXA exclusively at Ward's triangle. The DEXA lumbar spine BMD measurement was actually above the mean for young normal control subjects in 8 of the 24 men with osteoporosis by QCT BMD. In the 11 women with osteoporosis by QCT BMD, 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.
