Background: Turner syndrome (TS) has a variety of different karyotypes, with a wide range of phenotypic features, but the specific karyotype may not always predict the phenotype. TS with Y chromosome mosaicism may have mixed gonadal dysgenesis, and the mosaicism is related to the potential for gonadoblastoma.

Case Summary: In this case report, we report two cases of TS with different karyotypes and gonadal dysgenesis.

Objective: The aim of this study was to explore the possibility of creating a toxin, C-CPE-ETA', by fusing C-terminal high affinity binding domain of CPE (C-CPE) with a truncated form of Pseudomonas aeruginosa exotoxin A (ETA') and to examine whether C-CPE-ETA' could specifically target CLDN-3, 4 molecule and the targeted toxin was cytotoxic against CLDN-3,4-overexpressing ovarian cancer.

Methods: CLDN-3 and CLDN-4 expressions were analyzed at the mRNA level in three ovarian cancer cell lines and epithelial ovarian cancer tissues from 20 patients. After transforming an expression plasmid of C-CPE-ETA' into E.

Article Synopsis
  • Lysozymes play a crucial role in the innate immune system of invertebrates, particularly in combating bacterial infections.
  • A lysozyme gene from tiger shrimp was studied, revealing that it has a structure similar to chicken-type lysozymes, characterized by specific catalytic sites and conserved cysteine residues.
  • Despite high similarities among lysozymes in different shrimp species, their phylogenetic relationships do not align perfectly with traditional classifications, indicating more complex evolutionary connections.
