Abstract

A retrospective study of 87 patients who underwent posterior lumbar interbody fusion (PLIF) at L4-L5 for L4 degenerative spondylolisthesis. To clarify: 1) the correlation between radiologic degeneration of cranial adjacent segment and clinical results, 2) risk factors for radiologic degeneration of cranial adjacent segment, and 3) preoperative radiologic features of patients who underwent additional surgery with cranial adjacent segment degeneration. Whereas PLIF with pedicle screw fixation has shown satisfactory clinical results, a solid fusion has been reported to accelerate a degenerative change at unfused adjacent levels, especially in the cranial level. Although several authors have reported the adjacent segment degeneration after PLIF, there are no previous reports of risk factors for adjacent segment degeneration after PLIF. Eighty-seven patients who underwent PLIF for L4 degenerative spondylolisthesis and could be followed for at least 2 years were included in this study. We measured lumbar lordosis, scoliosis, laminar inclination angle at L3, facet sagittalization at L3-L4, facet tropism at L3-L4, preexisting disc degeneration at L3-L4, and lordosis at the fused segment. Progression of L3-L4 segment degeneration was de...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.
