Although early apoptotic AN+/PI(-) spermatozoa only negatively correlates with sperm motility, the differences in proportion of each subpopulation of spermatozoa (especially, the percentage of AN(-)/PI(-) spermatozoa), and decreased MMP might be significant markers for diagnosing male infertility. They possibly bring additional information to predict the outcome of in vitro fertilization.

ADHD is generally deemed to be a highly heritable disorder with mean heritability of 0.75. The enzyme monoamine oxidase (MAO), which has both A and B types, has long been considered a candidate pathological substrate for ADHD, and more recently, the genes for both MAO enzymes have been examined as mediators of the illness. Previous studies indicated that 30-50% of children with ADHD will experience symptoms that persist into adolescence and will have more significant impairment in social and neuropsychological functioning compared to those whose symptoms have remitted. Genes may also influence these characteristics of the disorder, and in this context MAO genes may also be candidates for moderating the presentation of ADHD. The current study examined the association between adolescent outcome of ADHD and MAO gene polymorphisms, including the 941T > G polymorphism in exon 8 (rs1799835) and 1460C > T polymorphism in exon 14 (rs1137070) of the MAOA gene, and the A > G polymorphism in intron13 (rs1799836), C > T polymorphism in the 3'UTR (rs1040399), and 2327T > C polymorphism in exon15 of the MAOB gene. Significant associations were observed between the MAOA gene polymorphisms and ADHD remission. Due to the small sample size and the possibility of phenotypic and etiologic heterogeneity of ADHD outcomes across ethnic or geographic groups, these results must be replicated before they can be generalized to other populations.

These results support the beneficial effect of fucoidan in 6-OHDA-lesioned rat model of PD. Fucoidan may suppress the Nox1-triggered oxidative stress in the SNc to protect DA neurons from 6-OHDA-induced toxicity and achieve its beneficial effect.
