Class II correction in orthodontic patients utilizing the Mandibular Anterior Repositioning Appliance (MARA)
Authors: Ardeshna Anil , Bogdan Frank , Jiang Shuying 
Published: January 2019

ABSTRACT

Objectives:
To evaluate skeletal and dentoalveolar changes produced by the Mandibular Anterior Repostioning Appliance (MARA) in the treatment of Class II malocclusion in adolescent patients.

Materials and Methods:
Lateral cephalograms of 24 patients, mean age 12.40 years, with a Class II malocclusion consecutively treated with MARA were compared with a historical control group. Changes were evaluated using the Pancherz superimposition and grid analysis pre- and posttreatment. Independent sample t-test, Mann-Whitney U-test, and Pearson correlation coefficient analysis were performed.

Results:
Significant differences were seen between the treatment and control groups during the 12 month period. Improvement in Class II relationship in the MARA group resulted from skeletal and dentoalveolar changes. There was a 7-mm molar correction and a 4.7-mm overjet reduction. There was also an increase in the mandibular base of 3.3 mm with the lower molar and incisor coming forward 2.6 mm and 2.2 mm, respectively. No significant headgear effect was shown on the maxilla. The maxillary incisor position remained unchanged, whereas the molar distalized 1.8 mm. The anterior lower facial height had an overall increase of 2.2 mm.

Conclusions:
The MARA was successful in achieving a Class I molar relationship and reducing the overjet in Class II malocclusions. This was the result of both skeletal and dentoalveolar changes.

Authors: Wu Bin , Zhao Siyu , Shi Haotian , Lu Ruxin , Yan Bin , Ma Songyun , Markert Bernd 
Published: January 2019

ABSTRACT

Objectives:
To determine the viscoelastic properties of the human periodontal ligament (PDL) using dynamic mechanical analysis (DMA).

Materials and Methods:
This study was carried out on three human maxillary jaw segments containing six upper central incisors and four lateral incisors. DMA was used to investigate the mechanical response of the human PDL. Dynamic sinusoidal loading was carried out with an amplitude of 3 N and frequencies between 0.5 Hz and 10 Hz. All samples were grouped by tooth positions and longitudinal locations.

Results:
An increase of oscillation frequency resulted in marked changes in the storage and loss moduli of the PDL. The storage modulus ranged from 0.808 MPa to 7.274 MPa, and the loss modulus varied from 0.087 MPa to 0.891 MPa. The tanδ, representing the ratio between viscosity and elasticity, remained constant with frequency. The trends for storage and loss moduli were described by exponential fits. The dynamic moduli of the central incisor were higher than those of the lateral incisor. The PDL samples from the gingival third of the root showed lower storage and loss moduli than those from the middle third of the root.

Conclusions:
Human PDL is viscoelastic through the range of frequencies tested: 0.5–10 Hz. The viscoelastic relationship changed with respect to frequency, tooth position, and root level.

In this research, it is aimed to analyse the educational messages about goals of social studies lessons in social novels and to show how often they are found.Data source of this research constitutes social novels, and the working group is fifteen (15) social novels on the "100 Temel Eser-100 Main Books" list which are suggested for primary school students by Educational Secretary Minister. Belongs in these list of novels eight (8) are Turkish literature and seven (7) are World literature. Since the written materials to be analysed in the research are novels, a document review was used as the data collection method. The analysis of the data obtained by using the document analysis technique within the context of the qualitative research method has been done through descriptive analysis. In the social novels that constituted the working group, it has been observed that concepts related to social participation skill were found to be involved the most common. It was followed by values and concepts of human rights. And the democracy concepts were found the least. It was followed by concepts of citizenship.
EL IDEAL HUMANISTA DE MEJORAMIENTO HUMANO Y SU INFLUENCIA EN VASCO DE QUIROGA
Authors: Sabido Sánchez Juárez Cecilia Guadalupe 
Published: January 2019

En esta investigación pretendo mostrar los elementos de humanismo presentes en el proyecto de creación de los «hospitales-pueblo» con los que Vasco de Quiroga pretendía responder a las necesidades que encontró al llegar al Nuevo Mundo. Para ello, señalaré una precisión relativa a las características del humanismo renacentista y las peculiaridades que tuvo en la Universidad de Salamanca de su tiempo; asimismo consideraré cómo influye en el proyecto de Vasco de Quiroga la experiencia profesional previa a su llegada a la Nueva España. Después retomaré las consideraciones humanistas de sus principales fuentes de inspiración y el modo en que pudo adecuarlas a las necesidades que detectó en las comunidades indígenas a su cargo. La idea central es que Vasco de Quiroga toma como punto de partida el ideal humanista de «mejoramiento humano», realizable a través de la palabra y la vida comunitaria; si bien este ideal es universal, lo encuentra especialmente viable en tierras americanas, dados sus hábitos y virtudes, a diferencia del estado de corrupción de la sociedad europea. En última instancia, la visión y el proyecto de Vasco de Quiroga contribuirán a instaurar un peculiar humanismo en el pensamiento y la vida práctica del mundo novohispano. Palabras clave: humanismo, humanismo cívico, renacimiento, república, mejoramiento humano, vida comunitaria, conquista.
Evaluation of vaporized hydrogen peroxide sterilization on the in vitro efficacy of meropenem-impregnated polymethyl methacrylate beads
Authors: Durham Myra E. , Elfenbein Johanna R. 
Published: January 2019

Abstract
OBJECTIVE To evaluate the effects of vaporized hydrogen peroxide (VHP) sterilization on the in vitro antimicrobial efficacy of meropenem-impregnated polymethyl methacrylate (M-PMMA) beads.
SAMPLE 6-mm-diameter polymethyl methacrylate beads that were or were not impregnated with meropenem.
PROCEDURES Meropenem-free polymethyl methacrylate and M-PMMA beads were sterilized by use of an autoclave or VHP or remained unsterilized. To determine the antimicrobial efficacy of each bead-sterilization combination (treatment), Mueller-Hinton agar plates were inoculated with 1 of 6 common equine pathogens, and 1 bead from each treatment was applied to a sixth of each plate. The zone of bacterial inhibition for each treatment was measured after 24 hours. To estimate the duration of antimicrobial elution into a solid or liquid medium, 1 bead from each treatment was transferred every 24 hours to a new Staphylococcus aureus–inoculated agar plate or a tube with PBS solution, and an aliquot of the eluent from each tube was then applied to a paper disc on an S aureus–inoculated agar plate. All agar plates were incubated for 24 hours, and the zone of bacterial inhibition was measured for each treatment.
RESULTS In vitro antimicrobial efficacy of M-PMMA beads was retained following VHP sterilization. The duration of antimicrobial elution in solid and liquid media did not differ significantly between unsterilized and VHP-sterilized M-PMMA beads.
CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that M-PMMA beads retained in vitro antimicrobial activity and eluted the drug for up to 2 weeks after VHP sterilization.
Morphometric evaluation of the portal vein by means of abdominal computed tomographic angiography in dogs free of vascular anomalies
Authors: Rossanese Matteo , Ferreira Amy , Maddox Thomas W. 
Published: January 2019

Abstract
OBJECTIVE To determine the mean diameter of the main portal vein (PV) in healthy dogs by use of CT angiography, identify any associations between PV diameter and certain dog characteristics, and validate a clinically valuable ratio for quantifying the size of the PV.
ANIMALS 100 dogs with no hepatic, cardiac, or vascular anomalies that underwent abdominal CT angiography.
PROCEDURES Diameters of the main PV, abdominal aorta (Ao), and caudal vena cava (CVC) were measured by 2 observers at a defined location on postcontrast CT angiographic images in axial, sagittal, and transverse planes. Dog characteristics were evaluated for associations with PV diameter, and a PV:Ao diameter ratio was calculated. Intraclass correlations were calculated to assess intra- and interobserver agreement in vessel diameter measurements.
RESULTS Mean diameter values were 7.9 mm (range, 4.1 to 14.8 mm) for the PV, 8.9 mm (range, 3.7 to 13.7 mm) for the Ao, and 11.4 mm (range, 4.4 to 22.5 mm) for the CVC. The PV:Ao diameter ratio was 0.91 mm. The PV diameter was significantly associated with dog body weight but not with dog age, sex, or neuter status. Intra- and interobserver reliabilities for measurements of all 3 vessels were considered excellent (intraclass correlation coefficients > 0.85).
CONCLUSIONS AND CLINICAL RELEVANCE Findings indicated that the PV:Ao diameter ratio was a repeatable measurement that may be useful for evaluating the size of the portal vasculature in dogs and possibly for distinguishing healthy PVs from abnormal PVs in dogs with hepatic vascular anomalies.

Published: January 2019

Abstract
OBJECTIVE To determine the effects of oral omeprazole administration on the fecal and gastric microbiota of healthy adult horses.
ANIMALS 12 healthy adult research horses.
PROCEDURES Horses were randomly assigned to receive omeprazole paste (4 mg/kg, PO, q 24 h) or a sham (control) treatment (tap water [20 mL, PO, q 24 h]) for 28 days. Fecal and gastric fluid samples were collected prior to the first treatment (day 0), and on days 7, 28, 35, and 56. Sample DNA was extracted, and bacterial 16S rRNA gene sequences were amplified and sequenced to characterize α and β diversity and differential expression of the fecal and gastric microbiota. Data were analyzed by visual examination and by statistical methods.
RESULTS Composition and diversity of the fecal microbiota did not differ significantly between treatment groups or over time. Substantial variation in gastric fluid results within groups and over time precluded meaningful interpretation of the microbiota in those samples.
CONCLUSIONS AND CLINICAL RELEVANCE Results supported that omeprazole administration had no effect on fecal microbiota composition and diversity in this group of healthy adult horses. Small sample size limited power to detect a difference if one existed; however, qualitative graphic examination supported that any difference would likely have been small and of limited clinical importance. Adequate data to evaluate potential effects on the gastric microbiota were not obtained. Investigations are needed to determine the effects of omeprazole in horses with systemic disease or horses receiving other medical treatments.

Published: January 2019

Abstract
OBJECTIVE To identify minimally invasive biomarkers to help differentiate dogs with gastric carcinoma from those with chronic gastritis.
DESIGN Prospective study.
ANIMALS 15 dogs with gastric carcinoma, 29 dogs with chronic gastritis, and 7 healthy dogs.
PROCEDURES Dogs with clinical signs of upper gastrointestinal tract disease for > 14 days that underwent gastroscopy or necropsy for collection of gastric biopsy specimens for histologic evaluation were prospectively enrolled. Gastric carcinoma and chronic gastritis were diagnosed on the basis of histologic findings. Additionally, gastric biopsy specimens were collected endoscopically from 7 healthy (control) dogs while they were anesthetized for a routine neutering procedure. Prior to being anesthetized for gastroscopy or euthanized, all dogs underwent a physical examination, and a blood sample was collected for quantification of select serum biomarker concentrations. Histologic findings, body condition score (BCS), and serum biomarker concentrations were compared among the 3 groups.
RESULTS Dogs with gastric carcinoma were significantly older and had a significantly lower BCS, lower serum folate concentration, and greater serum C-reactive protein (CRP) concentration, compared with dogs with chronic gastritis and control dogs.
CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that age > 8 years, BCS < 4, serum CRP concentration > 25 mg/L, and an abnormally low serum folate concentration might be useful noninvasive biomarkers for identification of dogs with gastric carcinoma. For underweight older dogs with signs of upper gastrointestinal tract disease and high serum CRP and low serum folate concentrations, gastric biopsy specimens should be obtained and evaluated so that a prompt definitive diagnosis can be made and appropriate treatment initiated.
Retrospective study of survival time and prognostic factors for dogs with small intestinal adenocarcinoma treated by tumor excision with or without adjuvant chemotherapy
Authors: Smith Ashley A. , Frimberger Angela E. , Moore Antony S. 
Published: January 2019

Abstract
OBJECTIVE To estimate survival time for dogs with small intestinal adenocarcinoma (SIACA) following tumor excision with or without adjuvant chemotherapy and to identify factors associated with survival time.
DESIGN Retrospective case series with a nested cohort study.
ANIMALS 29 client-owned dogs with surgically resected, histologically diagnosed SIACA.
PROCEDURES Medical records were reviewed and data collected regarding dog signalment; clinical signs; physical examination findings; PCV; serum total solids concentration; diagnostic imaging results; tumor size, location, and histologic characteristics (serosal extension, lymphatic invasion, surgical margins, and lymph node metastasis); type of adjuvant chemotherapy; NSAID administration; and survival time. Variables were assessed for associations with survival time and hazard rate via Kaplan-Meier and Cox proportional hazards analyses.
RESULTS Overall median survival time for dogs with SIACA following tumor excision was 544 days (95% confidence interval, 369 to 719 days). Based on Kaplan-Meier estimates, the 1- and 2-year survival rates were 60% and 36%, respectively. On multivariate analysis, only age category was an independent predictor of survival over the follow-up period. Dogs < 8 years of age had a significantly longer median survival time (1,193 days) than dogs ≥ 8 years (488 days). Lymph node metastasis, adjuvant chemotherapy, NSAID administration, and other assessed variables were not associated with survival time.
CONCLUSIONS AND CLINICAL RELEVANCE Findings suggested that SIACA in dogs carries a fair prognosis following excision, even when lymph node metastasis is present. Prospective studies are warranted to better characterize the effects of adjuvant chemotherapy or NSAID administration on survival time.
Outcome following computed tomographic imaging and subsequent surgical removal of keratomas in equids: 32 cases (2005–2016)
Authors: Katzman Scott A. , Spriet Mathieu , Galuppo Larry D. 
Published: January 2019

Abstract
OBJECTIVE To describe the use of CT in the diagnosis of and presurgical planning for equids with keratomas treated by hoof wall resection and determine postoperative complications and outcome.
DESIGN Retrospective case series.
ANIMALS 29 horses and 3 mules with keratomas treated by partial or complete hoof wall resection following CT imaging of the distal portion of the affected extremity from 2005 through 2016.
PROCEDURES For each equid, physical examination and lameness evaluation were performed, followed by imaging of the distal portion of the affected extremity. A tentative diagnosis of keratoma was made given results of clinical, radiographic, and CT examination, with the definitive diagnosis made on histologic examination. After CT imaging, each equid was treated with hoof wall resection.
RESULTS CT allowed accurate identification of the size and location of 35 keratomas in 33 feet. Thirty equids underwent partial and 2 underwent complete hoof wall resection for keratoma removal. Complications developed in 4 of 31 (13%) equids and included excessive granulation tissue formation at the surgical site (n = 1), excessive granulation tissue formation and worsening lameness (1), incomplete keratoma removal with suspected regrowth (1), and incomplete healing of the surgical site with distal interphalangeal joint sepsis secondary to repeated debridement of abnormal tissue (1). Twenty-eight of 31 (90%) equids returned to their previous activity level.
CONCLUSIONS AND CLINICAL RELEVANCE Preoperative CT examination of the feet was useful in the diagnosis of and surgical planning for keratomas in equids. A low complication rate was achieved with the described techniques.

Published: January 2019

Abstract
OBJECTIVE To describe a minimally invasive 3-portal laparoscopic approach for elective ovariohysterectomy and the outcome of that procedure in a population of goats.
DESIGN Descriptive clinical study.
ANIMALS 16 healthy client-owned goats.
PROCEDURES Food but not water was withheld from all goats for 24 hours before the procedure. Goats were anesthetized and positioned in dorsal recumbency. Three laparoscopic portals were created in the caudoventral portion of the abdomen, and the abdomen was insufflated to a maximum pressure of 10 mm Hg. A blunt-tip vessel sealer and divider device was used to transect the left and right mesovarium and mesometrium and uterus, and the resected tissue was removed from the abdomen. After hemostasis was verified, the portals were closed in a routine manner and anesthesia was discontinued. Goats were discharged from the hospital 24 hours after the procedure, and owners were contacted by telephone or email to obtain short- and long-term follow-up information by use of standardized questions.
RESULTS All procedures were performed by a surgeon and assistant surgeon. The procedure was not complex and was easily learned. No intraoperative complications were reported, and only 1 goat required rescue analgesia post-operatively. No other postoperative complications were recorded. Median surgery time was 43 minutes (range, 20 to 65 minutes). All owners were satisfied with the outcome of the procedure, and several perceived that the procedure improved goat behavior.
CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that laparoscopic ovariohysterectomy was a viable alternative for elective sterilization of female goats.
Factors of selection and quality of wood used for woodcraft in medieval Polish strongholds and early urban centres
Authors: Cywa Katarzyna , Wacnik Agnieszka , Lityńska-Zając Maria 
Published: January 2019

AbstractThis paper discusses various aspects of the use of wood for crafts in the Middle Ages, based on xylological analyses of 4211 crafted items of everyday use discovered at 62 archaeological sites in Poland. Over 1500 items were identified in the authors’ own analyses, and the remaining taxonomic data were taken from the literature. The research showed that the main types of wood used at the time were Pinus sylvestris, Quercus sp., Fraxinus excelsior, Picea sp. vel Larix sp., Taxus baccata, Alnus sp., Abies alba and Euonymus sp. Nineteen other taxa were used to make a much smaller pool of objects.At most of the analysed sites a similar set of materials was used to produce the items, regardless of their age and location. The choice of wood was selective and was based on the characteristics of particular tree and shrub species. Large coopered vessels were primarily made of wood from Quercus sp., Pinus sylvestris and Taxus baccata. The manufacture of turned utensils usually involved Fraxinus excelsior, while stave bowls were made using only Pinus sylvestris and Picea/Larix (mainly Picea abies).To verify the local availability of the source taxa, we used pollen sequences from natural and anthropogenic sites in the vicinity of the places where the examined artefacts were found. The choice of wood was limited by the availability of the trees and shrubs. In north-western Poland the most important taxa used for woodworking in the Middle Ages were Pinus sylvestris, Quercus sp., Fraxinus excelsior and Fagus sylvatica; in the south, Picea/Larix and Abies alba were used most frequently. Some items made of Abies alba, Picea and Larix were imported from other parts of the country.We inferred two stages of the use of wood by medieval Polish craftsmen. In the first stage, from the mid-10th century to the late 12th century, they largely used deciduous taxa; the second stage, from the 13th to the 15th centuries, saw the increased use of conifers.We found that the medieval craftsmen chose high-quality wood without defects. Radial wood with the best technical parameters was preferred. Its share increased in the late Middle Ages; this can be attributed to the craftsmen’s increasing familiarity with carpentry techniques.
