Rare mutations in IRF6 and GRHL3 cause Van der Woude syndrome, an autosomal dominant orofacial clefting disorder. Common variants in IRF6 and GRHL3 also contribute risk for isolated orofacial clefting. Similarly, variants within genes that encode receptor tyrosine kinase (RTK) signaling components, including members of the FGF pathway, EPHA3 and SPRY2, also contribute risk for isolated orofacial clefting. In the mouse, loss of Irf6 or perturbation of Fgf signaling leads to abnormal oral epithelial adhesions and cleft palate...

In the past decade, medical genetic research has generated multiple discoveries, many of which were obtained via genome-wide association studies (GWASs). A major GWAS finding is that the majority of risk variants for complex traits map to noncoding regions. This has resulted in a paradigm shift in terms of the interpretation of human genomic sequence variation, with more attention now being paid to what was previously termed "junk DNA." Translation of genetic findings into biologically meaningful results requires 1) large-scale and cell-specific efforts to annotate non-protein-coding regions and 2) the integration of comprehensive genomic data sets...

There is a group of lesions in the head and neck region derived from branchial arches and related structures which, when inflamed, are characterized by the formation of cysts lined by squamous or glandular epithelium and surrounded by a heavy inflammatory infiltrate rich in germinal centers. In the thyroid, the main source of various structures which may cause diagnostic dilemma is the ultimobranchial body. To investigate the spectrum of such thyroid lesions, the consultation files were reviewed for thyroid samples containing pathological structures regarded to arise from the ultimobranchial body...

The recognition of anions by designed receptors has attracted much attention in recent days. In particular, the selective binding of sulfate with artificial receptors is important because of its relevance to many biological and environmental applications. However, the development of organized molecular receptors with high-efficiency for sulfate binding still remains a significant challenge. We report a novel para-phenylene-bridged hexafunctional tripodal receptor that contains a urea-based inner cleft and a thiourea-based outer cleft, providing perfect sites for step-wise binding of two anions within a single cavity...

The pig is an important domestic animal that provides a larger amount of meat and serves as a biomedical animal model for human. Head and facial features are closely linked to identity recognition in mammal communication. To uncover the genetic architecture of swine head and facial features, we constructed 5 experimental pig populations and accurately measured 10 traits related to head and facial features, for which genome-wide association studies and meta-analysis were later carried out. As a result, we identified a total of 24 loci harboring 437 SNP on 8 swine chromosomes (SSC) that surpassed suggestively significant levels, of which 17 loci on 6 chromosomes exceeded the 5% genome-wide significance thresholds...

BACKGROUND: Implementation intentions enable individuals to translate good intentions into action. Parents and children can find maintaining oral health difficult, as evidenced by the presence of tooth decay. This is a common condition in children in spite of being preventable through the use of regular tooth brushing, fluoride protection and avoiding sugar intake. Even when parents and children are positive about looking after the teeth, they can face challenges in maintaining consistent habits...

In most types of cancer, overexpression of murine double minute 2 (MDM2) often leads to inactivation of p53. The crystal structure of MDM2, with a 109-residue amino-terminal domain, reveals that MDM2 has a core hydrophobic region to which p53 binds as an amphipathic α helix. The interface depends on the steric complementarity between MDM2 and the hydrophobic region of p53. Especially, on p53's triad, amino acids Phe19, Trp23 and Leu26 bind to the MDM2 core. Results from studies suggest that the structural motif of both p53 and MDM2 can be attributed to similarities in the amphipathic α helix...

RATIONALE: Cyclodialysis cleft is a relatively rare but severe condition with persistent ocular hypotony, which can cause morphologic changes and visual loss. Here we report a case of a traumatic cyclodialysis cleft that was successfully managed with direct cyclopexy via anterior chamber perfusion. During the operation, if there is aqueous humor flowing out of the deep scleral incision, the cleft is not closed, and surgery should continue until there is no aqueous outflow. PATIENT CONCERNS: A 66-year-old man was treated for severe blunt ocular trauma of the left eye and a resultant cyclodialysis cleft, lens subluxation, choroidal detachment and a cataract...

d-xylose, the main building block of plant biomass, is a pentose sugar that can be used by bacteria as a carbon source for bio-based fuel and chemical production through fermentation. In bacteria, the first step for d-xylose metabolism is signal perception at the membrane. We previously identified a three-component system in Firmicutes bacteria comprising a membrane-associated sensor protein (XylFII), a transmembrane histidine kinase (LytS) for periplasmic d-xylose sensing, and a cytoplasmic response regulator (YesN) that activates the transcription of the target ABC transporter xylFGH genes to promote the uptake of d-xylose...

Velopharyngeal insufficiency (VPI) represents an incomplete closure between the soft palate and the posterior pharyngeal wall. Its etiology can be anatomical (cleft palate), neurologic, or iatrogenic (after adenoidectomy). The evaluation of a VPI begins with a through speech and language assessment and can be complemented by instrumental investigations. VPI treatment relies on its early identification, followed by a specific speech therapy management. Surgery is performed in case of no improvement with speech therapy or in case of an anatomical defect not allowing the child to improve...

Cleft palate is among the most common congenital disorders, and can be induced by exposure to all‑trans retinoic acid (atRA) during mice and human embryogenesis. However, the mechanism underlying the implication of atRA in the development of cleft palate has yet to be elucidated. In the present study, atRA administered by gavage resulted in formation of a cleft palate in 99% of treated C57BL/6 mice. Notch2 was revealed to be upregulated in mouse embryonic palate mesenchymal (MEPM) cells in the atRA‑treated group compared with untreated control mice between embryonic day (E)12...

Pierre Robin sequence (PRS) is characterized by the triad micrognathia, glossoptosis, and airway obstruction, commonly associated with cleft palate. This study reports the case of a patient with characteristics consistent with the diagnosis of PRS in the 1(st) week of life. To stabilize the airway, oro-tracheal intubation was performed without success, followed by tracheostomy and glossopexy and after a small improvement in symptoms, it was decided to perform the mandibular distraction osteogenesis (MDO). At the age of 6, her maxillofacial development was within expectations, with patent airway, the presence of deciduous teeth, and without neurological impairment...

BACKGROUND: Triamcinolone acetonide (TAC) (Kenacort*) is a commonly used synthetic glucocorticoid in today's medical practice. The drug is also a potential agent in inducing cleft palates in rats. This drug has been used to induce cleft palate in the fetus of the pregnant rats to bring out a suitable animal model for human cleft lip and palate. The drug was given intraperitoneally to induce congenital cleft palate in pregnant mother rats. AIM: The aim of this study is to induce congenital cleft palate in pregnant Wister albino rats and reconstruct the defect with bone marrow mesenchymal stem cells (BMSCs) isolated from the same species along with PLGA (poly lactic co glycolic acid) scaffold...
