Classification and Treatment of Angle Class II Subdivision Malocculsions
<bold>Introduction:</bold> Patients with Class II subdivision malocclusions are a challenge for clinicians because re-establishing symmetry in one or both arches is often a treatment goal. In patients with a mandibular skeletal asymmetry, surgery is often one of the treatment options. However, …

VIRAL MODULATION OF MHC CLASS II-MEDIATED ANTIGEN PRESENTATION
… of antigen presentation cells (APC) perturbs MHC class II-mediated antigen (Ag) presentation. The goals of this project include: 1) to define mechanisms by which VV disrupts class II presentation; and 2) to examine whether disruption of the class II pathway by VV alters T cell responses in vitro …

Defining Mechanisms Contributing to Porcine MHC Class II Diversity
Comparisons of He in domestic and Wild populations revealed significant differences within Europe (P=0.031) at the DRB1 loci, but not the DQB loci (P=0.503). Within Asia, significant differences were observed (DQB: P=0.011 and DRB1: P=0.015) at both MHC loci, between the domestic and Wild boar …

Roles of Class II Histone Deacetylases in the Cardiovascular System
… mechanisms to control gene transcription. Class II histone deacetylases regulate developmental and physiological processes through interaction with and repression of a variety of transcription factors, including myocyte enhancer factor 2 (MEF2). Using gene targeting combined with …

Transcription regulation of the class II alcohol dehydrogenase 7 (ADH7)
The class IV alcohol dehydrogenase (ADH7, µ-ADH, σ-ADH) efficiently metabolizes ethanol and retinol. ADH7 is expressed mainly in the upper gastrointestinal tract with no expression in the liver unlike the other ADHs, and is implicated in various diseases including alcoholism, cancer and fetal …

Total synthesis of Class II and Class III Galbulimima Alkaloids
I. Total Synthesis of All Class III Galbulimima Alkaloids We describe the total synthesis of (+)- and (-)-galbulimima alkaloid 13, (-)-himgaline anad (-)-himbadine. The absolute stereochemistry of natural (-)-galbulimima alkaloid 13 is revised to 2S. Sequential use of catalytic cross-coupling and …

ACTN3 R577X GENOTYPES ASSOCIATE WITH CLASS II AND DEEP BITE MALOCCLUSIONS
… ACTN2 is expressed in slow type I and fast type II fibers whereas ACTN3 is expressed only in fast fibers. ACTN3 homozygosity for the 577X stop codon (i.e. changing 577RR to 577XX - the R577X polymorphism) results in the absence of alpha-actinin-3 in about 18% of Europeans, diminished fast …

The Effectiveness of Tipback Mechanics for Correction of Class II Malocclusion
… root uprighting. Lateral cephalograms of growing class II subjects taken at completion of leveling and aligning, after tipping back the molar, and after uprighting the molar roots were analyzed. The technique resulted in 1.95 mm distalization, 6.55 degrees distal tipping, and 1.4 mm extrusion of …

Computational Insights into the Antimicrobial Mechanism of Action of Class II Bacteriocins.
… work is to elucidate the mechanism of action of class II bacteriocins by employing a variety of computational methods that are built around atomistic molecular dynamics simulations. First, we studied Plantaricin EF, a two-peptide class IIb bacteriocin. This bacteriocin was simulated in different …

Cephalometric Evaluation of Mara Therapy in the Treatment of Class II Malocclusions
… cephalometric analysis of patients with Class II, division 1 malocclusions at the start of treatment. There were 51 children treated by a single clinician with a MARA in combination with Edgewise appliances. The comparison group consisted of subjects treated with fixed Edgewise appliances …

Orthodontic Outcomes in Class II Correction with Elastics: Clear Aligners Versus Fixed Appliances
… hygienic benefits; however, their efficacy in Class II correction with elastics remains under-researched compared to traditional fixed appliances. Specific Aims: This study compares anteroposterior and vertical dentoalveolar, facial, and skeletal changes between clear aligners and fixed …

Intrinsic Specificity of Binding and Regulatory Function of Class II bHLH Transcription Factors
… the shared genome. ASCL1, ASCL2, and MYOD are class II basic Helix-Loop-Helix (bHLH) transcription factors which play crucial roles in lineage specification in the developing embryo. In vivo, these factors bind to distinct genomic sites, and regulate distinct transcriptional programs. The …

Cephalometric Evaluation of Bionator Therapy in the Early Treatment of Class II Malocclusions
<p>Early or two-phase orthodontic treatment of Class II malocclusions is a debated topic in orthodontic circles primarily because the benefits of early intervention have not been consistently reproduced among researchers. The present study was a retrospective analysis of cephalograms from patients …

Changes in Pharyngeal Airway Dimensions Due to MARA Treatment in Class II Malocclusions
… different treatment modalities for correcting Class II malocclusions have on the pharyngeal airway volume. This retrospective study consisted of two groups of Class II patients: 38 patients (15 females, 23 males) treated with the MARA and an Edgewise appliance and 32 patients treated with an …
