  • association
  • Many genes have been implicated in the disorders of TDS, with genome wide association studies (GWAS) regularly identifying new gene variants that play a role in abnormal testes development. (wikipedia.org)
  • different
  • Importantly, the molecular tweezers have been found to be effective and safe not only in the test tube but also in animal models of different diseases, suggesting that they may be developed as drugs against diseases caused by abnormal protein aggregation, all of which currently have no cure.
