  2. 1. Telomeres and the brain : an investigation into the relationships of leukocyte telomere length with functional and structural attributes of the brain

    Abstract : Telomeres are the outermost parts of linear chromosomes. They consist of tandemly repeated non-coding short nucleotide sequences (TTAGGG in all vertebrates), in humans spanning over the last 2 to 15 kilobase pairs of the chromosome. Due to the end-replication problem, telomeres shorten with each cellular division. READ MORE

    Abstract : Opinions differ as to whether nocturnal enuresis is caused by high arousal thresholds, nocturnal polyuria or nocturnal bladder instability. In spite of the currently available therapeutic options - the antidiuretic drug desmopressin and alarm treatment - approximately 25% of children suffering from enuresis cannot be successfully treated.
