Outcomes of Single versus Double Fascicular Nerve Transfers for Restoration of Elbow Flexion in Patients with Brachial Plexus Injuries: A Systematic Review and Meta-Analysis.

Rna, Double-stranded

RNA consisting of two strands as opposed to the more prevalent single-stranded RNA. Most of the double-stranded segments are formed from transcription of DNA by intramolecular base-pairing of inverted complementary sequences separated by a single-stranded loop. Some double-stranded segments of RNA are normal in all organisms.

Dental Restoration, Temporary

A prosthesis or restoration placed for a limited period, from several days to several months, which is designed to seal the tooth and maintain its position until a permanent restoration (DENTAL RESTORATION, PERMANENT) will replace it. (From Jablonski, Dictionary of Dentistry, 1992)

Single-strand Specific Dna And Rna Endonucleases

Enzymes that catalyze the endonucleolytic cleavage of single-stranded regions of DNA or RNA molecules while leaving the double-stranded regions intact. They are particularly useful in the laboratory for producing "blunt-ended" DNA molecules from DNA with single-stranded ends and for sensitive GENETIC TECHNIQUES such as NUCLEASE PROTECTION ASSAYS that involve the detection of single-stranded DNA and RNA.

Apobec-3g Deaminase

An APOBEC deaminase that functions as an inhibitor of RETROVIRIDAE replication and inhibits the mobility of RETROTRANSPOSONS via deaminase-dependent and independent mechanisms. It is selective for SINGLE-STRANDED DNA and does not deaminate double-stranded DNA or single or DOUBLE-STRANDED RNA. It exhibits potent antiviral activity against VIF PROTEIN deficient HIV-1 through the creation of hypermutations in the VIRAL DNA. It also has anti-viral activity against SIMIAN IMMUNODEFICIENCY VIRUSES and HEPATITIS B VIRUS.

Nerve Fibers, Unmyelinated

A class of nerve fibers as defined by their structure, specifically the nerve sheath arrangement. The AXONS of the unmyelinated nerve fibers are small. The axons to SCHWANN CELLS ratio is greater in the unmyelinated nerve fibers than that in the myelinated fiber (NERVE FIBERS, MYELINATED) which is 1:1. Usually several axons are surrounded by a single Schwann cell in the unmyelinated nerve fibers. Therefore, each unmyelinated fiber is not completely covered by the MYELIN SHEATH formed by the Schwann cell. Unmyelinated nerve fibers conduct impulses at low velocities. They represent the majority of peripheral sensory and autonomic fibers. They are also found in the spinal cord and brain.
