Evaluation of Secondary Alveolar Bone Grafting for Unilateral Complete Cleft Alveolus: A Retrospective Cone Beam Computed Tomography-Based Study.

In patients with cleft lip and palate (CLP), secondary alveolar bone grafting (SABG) with particulate cancellous bone marrow (PCBM) is recommended. To compare bone graft outcomes in patients with unilateral CLP, when SABG is completed before or after canine tooth eruption (ACE or BCE), as measured by cone beam computed tomography (CBCT). Patients were allocated into two cohorts, ACE and BCE.

Intraoral Scanning Evaluation of Maxillary Arch Changes after Modified Sommerlad Palatoplasty for around Three Years.

Background: The purpose of this study was to investigate dental arch changes after modified Sommerlad palatoplasty in patients with cleft palate by intraoral scanning technique in children with early deciduous dentition.

Methods: This study included 60 patients with nonsyndromic unilateral complete cleft lip with palate or cleft palate only treated by modified Sommerlad palatoplasty without relaxed excision before 18 months of age and 95 healthy controls without cleft. Three-dimensional images of the maxillary dental arches of all participants at age 3 to 4 years were obtained by intraoral scanning technique.

Identification of putative regulatory single-nucleotide variants in NTN1 gene associated with NSCL/P.

Non-syndromic cleft lip with or without cleft palate (NSCL/P) is a common polygenetic disease. Although genome-wide association studies (GWAS) identified NTN1 gene as a high-priority candidate of NSCL/P, the comprehensive genetic architecture of NTN1 weren't yet known. Thus, this study aimed to determine full-scale genetic variants of NTN1 for NSCL/P in Chinese Han people.

Rs9891446 in NTN1 is associated with right-side cleft lip in Han Chinese population.

Objectives: This study aimed to reveal the association between single-nucleotide polymorphism of NTN1 and subtypes of non-syndromic cleft lip with or without cleft palate (NSCL/P) in Han Chinese Population.

Design: Initially, we selected three single-nucleotide polymorphisms (SNP) (rs4791331, rs4791774 and rs9891446) in NTN1 from previous genetic studies. Then we recruited two Han Chinese cohorts (2004 cases and 1823 controls) and divided cases into subgroups: non-syndromic right-side cleft lip, non-syndromic left-side cleft lip, non-syndromic bilateral cleft lip and non-syndromic cleft lip with palate to further evaluate the associations between the subtypes of NSCL/P and SNPs in NTN1.

Underwater Acoustic Sensor Networks Node Localization Based on Compressive Sensing in Water Hydrology.

Groundwater is an important source of human activities, agriculture and industry. Underwater Acoustic Sensor Networks (UASNs) is one of the important technologies for marine environmental monitoring. Therefore, it is of great significance to study the node self- localization technology of underwater acoustic sensor network.
