INTRODUCTION: For more than seven decades orthodontist used cephalometric analysis as one of the main diagnostic tools which can be performed manually or by software. The use of computers in treatment planning is expected to avoid errors and make it less time consuming with effective evaluation and high reproducibility. AIM: This study was done to evaluate and compare the accuracy and reliability of cephalometric measurements between computerized method of direct digital radiographs and conventional tracing...

The brain processes information through multiple layers of neurons. This deep architecture is representationally powerful, but complicates learning because it is difficult to identify the responsible neurons when a mistake is made. In machine learning, the backpropagation algorithm assigns blame by multiplying error signals with all the synaptic weights on each neuron's axon and further downstream. However, this involves a precise, symmetric backward connectivity pattern, which is thought to be impossible in the brain...

River water-quality studies rarely measure dissolved inorganic carbon (DIC) routinely, and there is a gap in our knowledge of the contributions of DIC to aquatic carbon fluxes and cycling processes. Here, we present the THINCARB model (THermodynamic modelling of INorganic CARBon), which uses widely-measured determinands (pH, alkalinity and temperature) to calculate DIC concentrations, speciation (bicarbonate, HCO3(-); carbonate, CO3(2-); and dissolved carbon dioxide, H2CO3(⁎)) and excess partial pressures of carbon dioxide (EpCO2) in freshwaters...

INTRODUCTION: Obesity is an epidemic in the pediatric population. Childhood obesity in trauma has been associated with increased incidence of long-bone fractures, longer ICU stays, and decreased closed head injuries. We investigated for differences in the likelihood of failure of non-operative management (NOM), and injury grade using a subset of a multi-institutional, prospective database of pediatric patients with solid organ injury (SOI). METHODS: We prospectively collected data on all pediatric patients (<18years) admitted for liver or splenic injury from September 2013 to January 2016...

UNLABELLED: Isolation following a good manufacturing practice-compliant, human islet product requires development of a robust islet isolation procedure where effective limits of key reagents are known. The enzymes used for islet isolation are critical but little is known about the doses of class I and class II collagenase required for successful islet isolation. METHODS: We used a factorial approach to evaluate the effect of high and low target activities of recombinant class I (rC1) and class II (rC2) collagenase on human islet yield...

AIM: The application of high-resolution MS to antibody-drug conjugate (ADC) drug development may provide insight into their safety and efficacy. Quantification of unconjugated cytotoxic drug (payload) and characterization of drug-to-antibody ratio distribution were determined in plasma using orthogonal acceleration quadrupole-time-of-flight MS. RESULTS: Unconjugated payload quantification determined by quadrupole-time-of-flight-based MRM(highresolution) and triple quadrupole-based multiple reaction monitoring were comparable and achieved detection limits of 0...

BACKGROUND: Patient and public involvement (PPI) in studies carried out by the UK Medical Research Council Clinical Trials Unit (MRC CTU) at University College London varies by research type and setting. We developed a series of case studies of PPI to document and share good practice. METHODS: We used purposive sampling to identify studies representing the scope of research at the MRC CTU and different approaches to PPI. We carried out semi-structured interviews with staff and patient representatives...

Context • Telomeres are repeated deoxyribonucleic acid (DNA) sequences (TTAGGG) that are located on the 5' ends of chromosomes, and they control the life span of eukaryotic cells. Compelling evidence has shown that the length of a person's life is dictated by the limited number of times that a human cell can divide. The enzyme telomerase has been shown to bind to and extend the length of telomeres. Thus, strategies for activating telomerase may help maintain telomere length and, thus, may lead to improved health during aging...

OBJECTIVE: To evaluate the influence of Tweed-Merrifield technique in correction of severe bimaxillary protrusion adult patients on the measurement of the dental and skeletal changes after orthodontic treatment by Johnston analysis and the regular cephalomatric analysis. METHODS: Twelve adolescent patients with severe bimaxillary protrusion were included in this self-control retrospective study. Lateral cephalometric radiographs were taken before and after treatments...

Polar tweed was discovered in mechanically stressed LaAlO3. Local patches of strained material (diameter ca. 5 μm) form interwoven patterns seen in birefringence images, Piezo-Force Microscopy (PFM) and Resonant Piezoelectric Spectroscopy (RPS). PFM and RPS observations prove unequivocally that electrical polarity exists inside the tweed patterns of LaAlO3. The local piezoelectric effect varies greatly within the tweed patterns and reaches magnitudes similar to quartz. The patterns were mapped by the shift of the Eg soft-mode frequency by Raman spectroscopy...

BACKGROUND: Sensory impairments increase with age and the majority of older people will experience a sensory impairment if they live long enough. However, the relationships of hearing, visual, and olfactory impairments with mortality are not well understood. METHODS: Epidemiology of Hearing Loss Study participants (n = 2,418) aged 53-97 years (mean = 69 years) were examined in 1998-2000 and hearing, visual acuity, and olfaction were measured. Participants were followed for mortality for up to 17 years (mean = 12...

The Antisocial Process Screening Device (APSD) is a well-supported tool for assessing psychopathic features in youth. However, most research with the APSD has been derived from clinical and forensic samples comprised mainly of male Caucasian and African American adolescents. In this prospective study, the incremental and predictive validity of the self-report APSD for violent and non-violent offending was examined in an ethnically diverse community sample of male and female youth (N = 335) aged 12 to 14. High-school students from a moderate sized city in Western Canada completed the self-report APSD and then completed the Self-Report of Offending 6 months later...

AIM: The study aimed to identify quantitative and relational characteristics of bone, dental and soft tissue structures for Class III malocclusion, according to gender and age range. MATERIAL AND METHODS: 60 conventional lateral cephalograms were divided into two groups according to ANB angle: the group of cases with skeletal Class III (n = 36) and a control group with skeletal Class I (n = 24). There were performed 53 digital cephalometric measurements according to Steiner, Tweed and Jarabak analyzes...
