Abstract

Many factors affect the outcomes of anterior cruciate ligament (ACL) reconstruction surgery. However, few studies have examined the effects of local bone conditions on the reconstruction of the ACL. This study investigated the changes in the local bone mineral density (BMD) of the knee after rupture of the ACL with the view of using this information to guide treatment options. Patients with ACL rupture treated in our department from January 2017 to April 2019 were enrolled in this study. Prior to surgery, local BMD measurements were obtained from all patients and used to determine the appropriate method of ligament fixation. If the local BMD of the affected knee was not significantly lower than that of the healthy side, extrusion fixation was conducted. If the BMD was significantly lower than that of the healthy knee, suspension fixation was applied. The conditions of tunnel cutting or screw splitting, and tunnel enlargement or screw pull-out were observed during the surgery. The post-surgical function of the knee joint was evaluated regularly by physical examination, imaging data, the IKDC scale score, and the Lysholm score. A total of 80 patients with unilateral ACL rupture were included. There were 64 males and 16 females. D...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.
