    “…A 1-month-old girl child, who was found to have hydrocephalus on prenatal ultrasound, was postnatally evaluated with magnetic resonance imaging (MRI) of brain, which showed two classical findings of septo-optic dysplasia (SOD), namely optic nerve hypoplasia and absent septum pellucidum. In addition, the patient was found to have cerebellar hemiagenesis.…”

    Septo-optic Dysplasia with Cerebellar Hemiagenesis
  3. 303
    “…This study demonstrates that capacitation triggers S-nitrosylation and S-glutathionylation (and reverse reactions) of zona-pellucida binding proteins, which may be a new important mechanism that determines the interaction between sperms and oocytes. …”

    A Primary Evaluation of Potential Small‐Molecule Inhibitors of the Astacin Metalloproteinase Ovastacin, a Novel Drug Target in Female Infertility Treatment
  18. 318
    “…Here we show that spermatozoa in gene-edited mice lacking a BTBD18 targeted pachytene piRNA cluster on Chr18 have severe sperm head dysmorphology, poor motility, impaired acrosome exocytosis, zona pellucida penetration and are sterile. The mutant phenotype arises from aberrant formation of proacrosomal vesicles, distortion of the trans-Golgi network, and up-regulation of GOLGA2 transcripts and protein associated with acrosome dysgenesis. …”
