Abstract

We investigated the relationships of ulnar varus deformity and the degree of cubitus varus according to the age at injury in patients with cubitus varus. Basic demographic factors were investigated in group 1 (injured at age younger than 5 years) and group 2 (injured at age 5-10 years). The uninjured side ulnar angle (UA) at the time of injury and final follow-up and the humeral-elbow-wrist angle (HEW-A) at final follow-up were measured. ΔUA (injured side - uninjured side UA at final follow-up) and ΔHEW-A (injured side - uninjured side HEW-A at final follow-up) were calculated and compared between the 2 groups. The correlation between ΔUA and ΔHEW-A was analyzed, and the degree of correlation was compared between the groups. Final UA and HEW-A on the injured side were increased more in group 1. ΔUA and ΔHEW-A were also more definitive in group 1. Positive correlations were found in both groups between ΔUA and ΔHEW-A, and the degree of correlation was similar in both groups. Distinct negative correlations were observed in both groups between the uninjured side UA at the time of injury and the ΔUA, but the degree of correlation differed significantly. The degree of ulnar varus correlated well with the degree of cubitus varus. A s...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.
