Development of the mammalian secondary palate involves highly dynamic morphogenetic processes, including outgrowth of palatal shelves from the oral side of the embryonic maxillary prominences, elevation of the initially vertically oriented palatal shelves to the horizontal position above the embryonic tongue, and subsequently adhesion and fusion of the paired palatal shelves at the midline to separate the oral cavity from the nasal cavity. Perturbation of any of these processes could cause cleft palate, a common birth defect that significantly affects patients' quality of life even after surgical treatment...

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...

OBJECTIVE: This study aimed to evaluate the craniofacial morphology of unoperated adult submucous cleft palate (SMCP) patients and to explore the possible correlation between the intrinsic growth insufficiency of the maxillofacial complex and the severity of the cleft. MATERIALS AND METHODS: A total of 20 unoperated SMCP patients, 20 unoperated overt cleft palate (OCP) patients, and 32 normal controls, ages between 18 and 30, were included for cephalometric analysis...

Two oxidovanadium(IV) complexes carrying Schiff base ligands obtained from the condensation of 4,5-dichlorobenzene-1,2-diamine and salicylaldehyde derivatives were synthesised and characterised, including their X-ray crystallographic structures. They were evaluated as dipeptidyl peptidase IV (DPP-IV) inhibitors for the treatment of type 2 diabetes. These compounds were moderate inhibitors of DPP-IV, with IC50 values of ca. 40μM. In vivo tests showed that complexes 1 and 2 could lower significantly the level of glucose in the blood of alloxan-diabetic mice at doses of 22...

Cleft palate is a common birth defect caused by disruption of palatogenesis during embryonic development. Although mutations disrupting components of the Wnt signaling pathway have been associated with cleft lip and palate in humans and mice, the mechanisms involving canonical Wnt signaling and its regulation in secondary palate development are not well understood. Here, we report that canonical Wnt signaling plays an important role in Pax9-mediated regulation of secondary palate development. We found that cleft palate pathogenesis in Pax9-deficient embryos is accompanied by significantly reduced expression of Axin2, an endogenous target of canonical Wnt signaling, in the developing palatal mesenchyme, particularly in the posterior regions of the palatal shelves...

First branchial cleft anomalies (FBCA) are rare in the clinical setting, as they account for 1 to 8% of all branchial abnormalities. The purpose of this study is to explore the relationship between the fistula tract and facial nerve and the surgical method of FBCA. This retrospective study included 30 cases of FBCA in children managed from 2009 to 2016. All patients underwent surgery to remove the tract of the FBCA. We reviewed the clinical data of the patients to obtain their demographics and management. Thirty patients (11 male and 19 female) with anomalies of FBCA were diagnosed...

Lysophospholipase_carboxylesterase (LPCE) has highly conserved homologs in many diverse species ranging from bacteria to humans, as well as substantial biological significance and potential therapeutic implications. However, its biological function and catalytic mechanism remain minimally investigated because of the lack of structural information. Here, we report the crystal structure of a bacterial esterase PE8 belonging to the LPCE family. The crystal structure of PE8 was solved with a high resolution of 1...

This study aimed to explore brain activation in patients with cleft lip and palate (CLP) using a Chinese character subvocalization task, in which the stimuli were selected from a clinical articulation evaluation test. CLP is a congenital disability. Individuals with CLP usually have articulation disorder caused by abnormal lip and palate structure. Previous studies showed that primary somatosensory and motor areas had a significant difference in activation in patients with CLP. However, whether brain activation was restored to a normal level after palatoplasty and speech rehabilitation is not clear...

PURPOSE: To assess the feasibility of acoustic rhinometry for the evaluation of velopharyngeal function in preschool children by detecting changes in nasal cavity volume (NV) and minimal cross-sectional area (MCSA) after palatoplasty. MATERIALS AND METHODS: Sixty-one preschool children with incomplete cleft palate who underwent Sommerlad palatoplasty were examined by acoustic rhinometry. MCSA, distance of the MCSA from the nostril (DMCA), NV, and nasopharyngeal volume (NPV) were measured...

BACKGROUND: Orofacial clefts (OFCs) are common human birth defects in China. However, studies on the prevalence of OFCs present inconsistent results. The overall prevalence and geographic distribution of OFCs are poorly described in China. Thus, we conducted a systematic review and meta-analysis to estimate the prevalence of OFCs. METHODS: The systematic review and meta-analysis were conducted on the basis of an established protocol (PROSPERO 2015: CRD42015030198)...

Müller cells maintain retinal synaptic homeostasis by taking up glutamate from the synaptic cleft and transporting glutamine back to the neurons. To study the interaction between Müller cells and photoreceptors, we injected either DL-α-aminoadipate or L-methionine sulfoximine-both inhibitors of glutamine synthetase-subretinally in rats. Following injection, the a-wave of the electroretinogram (ERG) was attenuated, and metabotropic glutamate receptor 5 (mGluR5) was activated. Selective antagonism of mGluR5 by 2-methyl-6-(phenylethynyl)-pyridine increased the ERG a-wave amplitude and also increased rhodopsin expression...

OBJECTIVE: The aims of this study were to propose a new method for volumetric assessment of alveolar bone grafting and to quantitatively assess alveolar bone grafting based on this method. STUDY DESIGN: Cone beam computed tomography images of 18 patients with unilateral cleft alveolus were selected.

Bovine leukemia virus (BLV) infections, causing persistent lymphocytosis and lethal lymphosarcoma in cattle, have reached high endemicity on dairy farms. We observed extensive inter-individual variation in the level of infection (LI) by assessing differences in proviral load in peripheral blood. This phenotypic variation appears to be determined by host genetics variants, especially those located in the BoLA-DRB3 MHCII molecule. We performed an association study using sequencing-based typed BOLA-DRB3 alleles from over 800 Holstein and Holstein × Jersey cows considering LI in vivo and accounting for filial relationships...

BACKGROUND: Xylanases have been widely employed in many industrial processes, and thermophilic xylanases are in great demand for meeting the high-temperature requirements of biotechnological treatments. In this work, we aim to improve the thermostability of XynCDBFV, a glycoside hydrolase (GH) family 11 xylanase from the ruminal fungus Neocallimastix patriciarum, by site-directed mutagenesis. We report favorable mutations at the C-terminus from B-factor comparison and multiple sequence alignment...

Purpose: To determine nasalance scores of Brazilian Portuguese speaking children without evident speech disorders, language delay and orofacial deformities, at age 5 years, and analyze differences between types of speech samples and genders. Methods: Twenty children were analyzed, 11 males, age ranging from 4 years and 10 months to 5 years and 11 months. The Nasometer II 6450 (KayPENTAX) was used for nasalance assessment. Speech samples were eight consonant-vowel syllables and one sequence of nine words...

BACKGROUND: Nonsyndromic orofacial clefts (NSOC) are the most common orofacial congenital defect with a complex etiology. Genome-wide association studies have identified paired box protein 7 (PAX7) and netrin-1 (NTN1) as candidate susceptibility genes for NSOC in both European and Asian populations. Here, possible associations between single-nucleotide polymorphisms (SNPs) in or near PAX7 and NTN1 were investigated in relation to risk of NSOC in a northern Chinese population. METHODS: A total of 602 individuals with NSOC and 510 controls were recruited from northern China...
