Published: August 2007

Abstract
Objective: To test the null hypothesis that premolar autotransplantation is not successful for orthodontic patients.
Materials and Methods: In the present study, 28 premolar transplants from 24 orthodontic patients were associated with orthodontic treatment. At a routine 3-month appointment, patients underwent a dental radiograph and a chair-side observation for periodontal problems. Three sets of dental radiographs were taken by one dental assistant using a custom holder at: preoperation (T0), 2 year postoperation (T1), and retention (T2) (4- to 14-year follow-up observation) stages. All transplants were conducted in a one-phase operation by one operator (Dr Inoue). Recipient sites were: ten for missing maxillary canines, nine for maxillary centrals and laterals, eight for lower second premolar, and five for other missing premolar sites. All recipients maintained the retained primary tooth with a socket.
Results: The success ratio of all 28 transplants was 100%, although four transplants shorter than a 4-year period of observation were omitted. Two transplant patients, one with a medical history of histiocytosis and the other with a history of osteomyelitis of the maxilla without a recipient socket, were also excluded from this study. Eleven of 22 premolar transplants had a root canal treatment (RCT), four of which had RCT within 2 years after the operation.
Conclusions: The null hypothesis was rejected. The success ratio of premolar transplants was 100%.

Published: August 2007

Abstract
Objective: To investigate which hard and soft tissue factors relate with the amount of buccal corridor area (BCA) during posed smiling.
Materials and Methods: The samples consisted of 92 adult patients (19 men and 73 women; 56 four first bicuspids extraction and 36 nonextraction treatment cases; mean age = 23.5 years), who were treated only with a fixed appliance and finished with Angle Class I canine and molar relationships. To eliminate the crowding effect on the buccal corridor area, lateral cephalograms, dental casts, and standardized frontal posed smile photographs were obtained at debonding stage and 28 variables were measured. Pearson correlation analysis, multiple linear regression analysis, and independent t-test were used to find variables that were related with buccal corridor area ratio (BCAR).
Results: Among the lateral cephalometric and dental cast variables, FMA, lower anterior facial height, upper incisor (U1) exposure, U1 to facial plane, lower incisor (L1) to mandibular plane, L1 to N-B, Sn (subnasale) to soft tissue menton (Me′), Sn to stomodium superius (stms), stms to Me′, and interpremolar width were significantly negatively correlated with BCAR. Occlusal plane inclination and buccal corridor linear ratio did not show any significant correlation with BCAR. Multiple linear regression analysis generated a three-variable model: Sn to Me′, U1 exposure, and sum of tooth material (STM) (R2 = 0.324). There was no significant difference in BCAR between extraction and nonextraction groups.
Conclusions: To control the amount of BCA for achieving a better esthetic smile, it is necessary to observe the vertical pattern of the face, amount of upper incisor exposure, and sum of the tooth material.

Published: August 2007

AbstractObjective: To determine the success rate and the factors related to the success rate of orthodontic miniscrew implants (OMI) placed at the attached gingiva of the posterior buccal region.Materials and Methods: Four hundred eighty OMI placed in 209 orthodontic patients were examined retroactively. The sample was divided into young patients (range 10–18 years, N = 108) and adult patients (range 19–64 years, N = 109). The placement site was divided into three interdental areas from the first premolar to the second molar in the maxilla and mandible. According to soft tissue management, the samples were divided into incision and nonincision groups. Chi-square tests and multiple logistic regression analyses were used.Results: The overall success rate was 83.8%. Dislodgement of the OMI occurred most frequently in the first 1–2 months, and more than 90% of the failures occurred within the first 4 months. Sex, age, jaw, soft tissue management, and placement side did not show any difference in the success rate. Placement site, however, showed a significant difference in the mandible of adult patients. There was no difference in the success rate in the maxilla.Conclusions: Placement site is one of the important factors for success rate of OMI.

Abstract
Objective—To determine trends in urolith composition in cats.
Design—Retrospective case series.
Sample Population—5,230 uroliths.
Procedures—The laboratory database for the Gerald V. Ling Urinary Stone Analysis Laboratory was searched for all urolith submissions from cats from 1985 through 2004. Submission forms were reviewed, and each cat's age, sex, breed, and stone location were recorded.
Results—Minerals identified included struvite, calcium oxalate, urates, dried solidified blood, apatite, brushite, cystine, silica, potassium magnesium pyrophosphate, xanthine, and newberyite. During the past 20 years, the ratio of calcium oxalate stones to struvite stones increased significantly. When only the last 3 years of the study period were included, the percentage of struvite stones (44%) was higher than the percentage of calcium oxa-late stones (40%). The most common location for both types of uroliths was the bladder. The number of calcium oxalate-containing calculi in the upper portion of the urinary tract increased significantly during the study period. The number of apatite uroliths declined sig-nificantly and that of dried solidified blood stones increased significantly, compared with all other stone types. No significant difference in the number of urate stones was detected.
Conclusions and Clinical Relevance—The increasing proportion of calcium oxalate uroliths was in accordance with findings from other studies and could be a result of alterations in cats' diets. However, the decreased percentage of calcium oxalate calculi and increased percentage of struvite calculi observed in the last 3 years may portend a change in the fre-quency of this type of urolith.

Published: August 2007

Abstract
Objective—To determine the incidence of equine herpesvirus-1 (EHV-1) infection among Thoroughbreds residing on a farm on which the virus was known to be endemic.
Design—Prospective cohort study.
Animals—10 nonpregnant mares, 8 stallions, 16 weanlings, 11 racehorses, and 30 pregnant mares and their foals born during the 2006 foaling season.
Procedures—Blood and nasopharygeal swab samples were collected every 3 to 5 weeks for 9 months, and placenta and colostrum samples were collected at foaling. All samples were submitted for testing for EHV-1 DNA with a PCR assay. A type-specific EHV-1 ELISA was used to determine antibody titers in mares and foals at birth, 12 to 24 hours after birth, and every 3 to 5 weeks thereafter.
Results—Results of the PCR assay were positive for only 4 of the 1,330 samples collected (590 blood samples, 590 nasopharyngeal swab samples, 30 placentas, and 30 colostrum samples), with EHV-1 DNA detected in nasal secretions from 3 horses (pregnant mare, stallion, and racehorse) and in the placenta from 1 mare. Seroconversion was detected in 3 of 27 foals during the first month of life.
Conclusions and Clinical Relevance—Results suggested that there was a low prevalence of EHV-1 infection among this population of Thoroughbreds even though the virus was known to be endemic on the farm and that pregnant mares could become infected without aborting. Analysis of nasopharyngeal swab samples appeared to be more sensitive than analysis of blood samples for detection of EHV-1 DNA.

Authors: Thunes Clair , Carpenter Tim E. 
Published: August 2007

Abstract
Objective—To determine biosecurity practices and travel history of individuals exhibiting livestock at the 2005 California State Fair.
Design—Survey.
Study Population—137 individuals exhibiting livestock at the fair.
Procedures—Exhibitors were asked to complete a survey to gather information about the animals they exhibited, the biosecurity practices they used, and the distances they traveled to exhibit their animals.
Results—132 of the 137 (96%) respondents came from California, with respondents representing 40 of California's 58 counties. Median number of livestock exhibitions attended by respondents during the past 12 months was 3 (range, 1 to 7). Respondents indicated that 787 of the 812 (97%) animals they exhibited would be returned home after the fair. Nine (7%) respondents indicated that they did not take any particular biosecurity precautions before arriving at the fair, and 14 (10%) indicated that they did not take any particular biosecurity precautions while at the fair. Only 36 (26%) respondents indicated that they quarantined their animals when returning to their farm of residence after the fair.
Conclusions and Clinical Relevance—Results indicated that there was extensive movement of livestock among exhibitions in California, posing a potential threat for widespread dispersion of disease throughout the state and beyond, particularly given the low percentages of exhibitors who used various biosecurity measures.
Copper toxicosis in a dairy goat herd
Authors: Cornish Jennifer , Angelos John , Puschner Birgit , Miller Grant , George Lisle 
Published: August 2007

Abstract
Case Description—A closed herd of 400 mixed-breed dairy goats was examined because of a decrease in milk production and increase in mortality rate. Nine animals had died within a 1-month period.
Clinical Findings—Clinical signs were evident only in lactating goats and included anorexia and recumbency. In the most severely affected goats, signs progressed to neurologic abnormalities and death. Serum aspartate aminotransferase activity, γ-glutamyltransferase activity, and total bilirubin concentration were high in clinically affected does, but no evidence of hemolysis was found. A diagnosis of copper toxicosis was made on the basis of high liver and kidney copper concentrations and histologic evidence of hepatic necrosis. Goats were found to have been fed a mineral mix containing 3,050 ppm copper for 9 months prior to the onset of copper toxicosis. Overall, there was no consistent relationship between serum hepatic enzyme activities, serum copper concentration, and liver copper concentration.
Treatment and Outcome—Clinically affected goats were treated with penicillamine, ammonium molybdate, sodium thiosulfate, and vitamin E. Penicillamine increased urine copper excretion in treated does versus untreated control animals. An increased incidence of infectious disease was identified in the herd 9 months later. Liver vitamin E concentration was low in 10 of the 12 goats that underwent necropsy.
Clinical Relevance—Findings suggested that penicillamine may be an effective treatment for goats with copper toxicosis. Production losses months after the diagnosis was made suggested that the intoxication had a prolonged animal welfare and economic impacts.

Authors: Venn-Watson Stephanie , Jensen Eric D. , Ridgway Sam H. 
Published: August 2007

Abstract
Objective—To establish reference ranges for hematologic and serum biochemical variables in healthy Atlantic bottlenose dolphins (Tursiops truncatus) of known age and sex that were housed in open ocean water.
Design—Original study.
Sample Population—1,113 blood samples collected from 52 healthy bottlenose dolphins housed in open ocean water during 1998 to 2005.
Procedures—Data obtained from analyses of blood samples that had been collected for routine purposes from dolphins were analyzed with respect to sex and age of the dolphins. Each dolphin was categorized into 1 of 4 groups: 1 to 5 years (calf), > 5 to 10 years (juvenile), > 10 to 30 years (adult), or > 30 years (geriatric). Retrospective ANCOVA was performed for 30 hematologic and serum biochemical variables, with age and sex as cofactors.
Results—Among healthy bottlenose dolphins, age and sex significantly affected 23 of 30 (76.7%) and 11 of 30 (36.7%) hematologic and serum biochemical variables, respectively.
Conclusions and Clinical Relevance—Results indicated that age and sex significantly affected clinicopathologic reference ranges in our healthy bottlenose dolphin population. When assessing clinicopathologic variables in bottlenose dolphins, age and sex should be taken into consideration. The data obtained suggested reference ranges for healthy man-aged bottlenose dolphin populations housed in open ocean water by age and sex.
Cerebrovascular accident in β‐thalassemia major (β‐TM) and β‐thalassemia intermedia (β‐TI)

Published: August 2007

AbstractChronic hypercoagulable state expressed clinically by thromboembolic events has been described in thalassemia. One of the affected organs is the brain where symptomatic and asymptomatic damage has been reported. The present report describes seven cases who presented with the signs of cerebrovascular accident (CVA), five ischemic and two with hemorrhage. Two of them died. All patients were splenectomized, five received regular blood transfusions, and their ferritin levels were between 1,200 and 3,000 mg %. In addition, four patients had congestive heart failure and atrial fibrillation, and three had “Bronze diabetes,” The recommendation on the basis of the results is that well‐designed clinical trials are indicated to monitor asymptomatic brain damage by magnetic resonance imaging in splenectomized patients over the age of 20 years, who are not regularly transfused and have a high risk to develop thromboembolic events. In this subset of patients, anticoagulant and/or antiplatelet therapy should be considered. Moreover, treatment of additional complications resulting from iron overload, which may contribute to the etiology of CVA such as cardiac failure and arrhythmia with or without “bronze diabetes,” is mandatory.

AbstractThe silencing of tumor suppressor genes associated with increased DNA methylation of the promoter regions is a frequent observation in many forms of cancer. Reactivation of these genes using pharmacological inhibitors of DNA methyltransferase such as 5‐aza‐2′‐deoxycytidine (decitabine) is a worthwhile therapeutic goal. The effectiveness and tolerability of low‐dose intravenous and subcutaneous decitabine regimens to demethylate and reactivate expression of the methylated γ‐globin gene in baboons and in patients with sickle cell disease led to successful trials of low‐dose regimens of this drug in patients with myelodysplastic syndrome. Since these low‐dose regimens are well‐tolerated with minimal toxicity, they are suitable for chronic dosing to maintain promoter hypomethylation and expression of target genes. The development of an orally administered therapy using DNA methyltransferase inhibitors would facilitate such chronic approaches to therapy. We tested the ability of decitabine and a new salt derivative, decitabine mesylate, to reactivate the methylated γ‐globin gene in baboons when administered orally. Our results demonstrate that oral administration of these drugs at doses 17–34 times optimal subcutaneous doses of decitabine reactivates fetal hemoglobin, demethylates the ϵ‐ and γ‐globin gene promoters, and increases histone acetylation of these promoters in baboons (Papio anubis).

AbstractObjectiveNipah virus (NiV) is an emerging zoonosis. Central nervous system disease frequently results in high case‐fatality. Long‐term neurological assessments of survivors are limited. We assessed long‐term neurologic and functional outcomes of 22 patients surviving NiV illness in Bangladesh.MethodsDuring August 2005 and May 2006, we administered a questionnaire on persistent symptoms and functional difficulties to 22 previously identified NiV infection survivors. We performed neurologic evaluations and brain magnetic resonance imaging (MRI).ResultsTwelve (55%) subjects were male; median age was 14.5 years (range 6–50). Seventeen (77%) survived encephalitis, and 5 survived febrile illness. All but 1 subject had disabling fatigue, with a median duration of 5 months (range, 8 days–8 months). Seven encephalitis patients (32% overall), but none with febrile illness had persistent neurologic dysfunction, including static encephalopathy (n = 4), ocular motor palsies (2), cervical dystonia (2), focal weakness (2), and facial paralysis (1). Four cases had delayed‐onset neurologic abnormalities months after acute illness. Behavioral abnormalities were reported by caregivers of over 50% of subjects under age 16. MRI abnormalities were present in 15, and included multifocal hyperintensities, cerebral atrophy, and confluent cortical and subcortical signal changes.InterpretationAlthough delayed progression to neurologic illness following Nipah fever was not observed, persistent fatigue and functional impairment was frequent. Neurologic sequelae were frequent following Nipah encephalitis. Neurologic dysfunction may persist for years after acute infection, and new neurologic dysfunction may develop after acute illness. Survivors of NiV infection may experience substantial long‐term neurologic and functional morbidity. Ann Neurol 2007
Controlled Stability of the Triple‐Stranded Helical Structure of a β‐1,3‐Glucan with a Chromophoric Aromatic Moiety at a Peripheral Position

Published: August 2007

AbstractWe synthesized a semiartificial β‐1,3‐glucan, curdlan with dialkylaniline groups (CUR‐DA), that bears chromophoric aromatic groups at its peripheral positions. Spectroscopic studies as well as microscopic observations indicate that CUR‐DA adopts a triple‐stranded helical structure in water‐ or methanol‐rich solutions of dimethyl sulfoxide (DMSO). This triple‐stranded helical structure exhibits high thermal stability and resistance to base, attributes that are similar to those of the triple‐stranded helical structure of native β‐1,3‐glucans such as schizophyllan. Moreover, we found that the stability of the triple‐stranded helical structure can be easily modulated by solvent composition and metal‐ion (Zn2+) binding. As β‐1,3‐glucan polysaccharides are known to serve as “polymeric” hosts, including certain DNA molecules, carbon nanotubes, and conjugated polymers, and complexation occurs only with the single‐stranded structure, this information is very useful for the creation of these attractive polymeric composites, the controlled release of DNA, and so on.
Coexistence of Hydrogen‐Bonded Loop and Extended Tetrapeptide Conformations

Published: August 2007

AbstractThe conformations of a protected tetrathiopeptide have been analysed by isotope labelling and two‐dimensional infrared spectroscopy (2D‐IR). It has been found that Boc‐Ala‐Gly(S)‐Ala‐Aib‐OMe in acetonitrile, as well as its oxopeptide analogue, can adopt a hydrogen‐bonded loop conformation in coexistence with less restricted structures. The two types of conformations interconvert too quickly to be resolved on the nuclear magnetic resonance (NMR) timescale, but give rise to different cross peaks in two‐dimensional infrared spectra. The hydrogen bond between the Boc terminal group and the amide proton of Aib can be broken by photoisomerisation of the thioamide bond.

Published: August 2007

AbstractThe development of a new synthetic approach to acrylates based on the formation of alkyl esters of acrylic acids has been studied. A preformed Pd–COOMe moiety is used as a model system to investigate the insertion of an olefin into the PdC bond. The fast elimination of acrylate is observed. Density functional calculations support the experimental findings and allow the characterization of transition states along the reaction pathway. The first example of olefin/CO2 coupling with facile release of ethyl acrylate is also presented.
