Craniofacial Analysis May Indicate Co-Occurrence of Skeletal Malocclusions and Associated Risks in Development of Cleft Lip and Palate.

Non-syndromic orofacial clefts encompass a range of morphological changes affecting the oral cavity and the craniofacial skeleton, of which the genetic and epigenetic etiologic factors remain largely unknown. The objective of this study is to explore the contribution of underlying dentofacial deformities (also known as skeletal malocclusions) in the craniofacial morphology of non-syndromic cleft lip and palate patients (nsCLP). For that purpose, geometric morphometric analysis was performed using full skull cone beam computed tomography (CBCT) images of patients with nsCLP ( = 30), normocephalic controls ( = 60), as well as to sex- and ethnicity- matched patients with an equivalent dentofacial deformity ( = 30).

Tissue-specific gene delivery via nanoparticle coating.

The use of biomaterials for gene delivery can potentially avoid many of the safety concerns with viral gene delivery. However, the efficacy of polymeric gene delivery methods is low, particularly in vivo. One significant concern is that the interior and exterior composition of polymeric gene delivery nanoparticles are often coupled, with a single polymer backbone governing all functions from biophysical properties of the polymer/DNA particle to DNA condensation and release.

Adeno-associated virus-mediated expression of kallistatin suppresses local and remote hepatocellular carcinomas.

Background: The current treatments for hepatocellular carcinoma (HCC) are poor, particularly for metastatic HCC. Intraportal transfusion of adeno-associated virus (AAV) leads to long-term and persistent transgenic expression in livers. Kallistatin, a novel angiogenesis inhibitor, exhibits anti-tumor activity.
