Abstract

To determine the relationship between femoral notch morphology, femoral notch width index and anterior cruciate ligament tears using magnetic resonance imaging of the knee. This retrospective study was conducted on 560 patients who had magnetic resonance imaging (MRI) examinations of the knee between February 2010 and June 2011. Two morphological changes were investigated: the shape of the femoral notch and its width index. The femoral notch shape was classified into one of three types: Type A, which is a narrow (Stenotic) notch that appears narrowed from the base to the midsection as well as at the apex; Type U, in which the midsection does not taper, allowing for a wider contour to the notch than Type A; and Type W, which has the characteristics of Type U but with two apparent apices. The femoral notch width index was calculated as a ratio of central notch width and transcondylar or intercondylar width; values of 0.270 or more were considered as normal and values of 0.269 or less were considered as below normal. These measurements were correlated with the presence or absence of anterior cruciate ligament (ACL) tears. Of 560 patients, there were 280 cases of ACL tear. Of the 560 patients, 240 had a Type A femoral notch shape a...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.
