A conserved non-coding sequence (CNS) is a DNA sequence of noncoding DNA that is evolutionarily conserved. These sequences are of interest for their potential to regulate gene production. [1] CNSs in plants [2] and animals [1] are highly associated with transcription factor binding sites and other cis-acting regulatory elements.
DNA analysis is generally used to determine if parents are carriers of the mutant gene. [27] Prenatal diagnosis through either DNA analysis or determination of NAA in amniotic fluid (which would be increased in an affected pregnancy) can also be used when DNA analysis cannot be performed on parents. [28]
Primary central nervous system lymphoma (PCNSL), also termed primary diffuse large B-cell lymphoma of the central nervous system (DLBCL-CNS), [2] is a primary intracranial tumor appearing mostly in patients with severe immunodeficiency (typically patients with AIDS). It is a subtype and one of the most aggressive of the diffuse large B-cell ...
A central nervous system tumor (CNS tumor) is an abnormal growth of cells from the tissues of the brain or spinal cord. [1] CNS tumor is a generic term encompassing over 120 distinct tumor types. [2] Common symptoms of CNS tumors include vomiting, headache, changes in vision, nausea, and seizures. [3]
Nucleic acid NMR is the use of nuclear magnetic resonance spectroscopy to obtain information about the structure and dynamics of nucleic acid molecules, such as DNA or RNA.It is useful for molecules of up to 100 nucleotides, and as of 2003, nearly half of all known RNA structures had been determined by NMR spectroscopy.
Certain anatomical sites exhibit a heightened risk for CNS relapse due to their proximity to the central nervous system or unique immune properties. The most widely recognized sites are the kidney and adrenal glands, which have already been incorporated into the CNS-IPI score. Breast and testicular involvement show growing significance as well.

Resonance Raman spectroscopy with ultraviolet excitation can be used to examine the chemistry, structure, and intermolecular interactions of nucleic acids, specifically the bases. Interactions between nucleic acids and DNA-binding compounds such as drugs can be examined by selectively exciting either the nucleobases or the drug itself. [8]
CNS metastasis is the spread and proliferation of cancer cells from their original tumour to form secondary tumours in portions of the central nervous system. [ 1 ] The process of tumour cells invading distant tissue is complex and obscure, but modern technology has permitted an enhanced detection of metastasis .
