Abstract

We sought to compare the clinical and radiological results of instrumented posterior lumbar interbody fusion (PLIF) using unilateral or bilateral polyetheretherketone cages and pedicle screws. One hundred eighty-seven cases of degenerative spine that had been followed for at least 18 months were reviewed retrospectively. In 88 cases (147 levels), one cage was inserted, and in 99 cases (152 levels), two cages were inserted. Visual analog scale, Oswestry disability index, and functional rating indices were measured. Lumbar lordosis, lumbar scoliotic and fusion level scoliotic angles, and stable fixation were determined before surgery and 12 months postoperatively on standing x-rays. Amounts of intra- and postoperative blood loss, total quantities transfused, and operation times were also evaluated. No significant differences were found between the two groups in terms of visual analog scale, Oswestry disability index, functional rating indices, lumbar lordosis, lumbar scoliotic angles, fusion level scoliotic angles, or fixation stabilities. However, the amounts of postoperative blood loss, total blood loss, and total transfusion for two-level PLIF using a unilateral cage were statistically smaller than those for two-level PLIF usi...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.
