Authors: Dai Tian-Jun , Liu Yu-Chen , Fan Xu-Dong , Liu Xing-Zhao , Xie Dan , Li Yan-Rong
Published: October 2018

The unique structural and physical properties of two-dimensional (2D) atomic layer semiconductors render them promising candidates for electronic or optoelectronic devices. However, the lack of efficient and stable approaches to synthesize large-area thin films with excellent uniformity hinders their realistic applications. In this work, we reported a method involving atomic layer deposition and a chemical vapor deposition chamber to produce few-layer 2H-MoSe2 thin films with wafer-level uniformity. The reduction of MoO3 was found indispensable for the successful synthesis of MoSe2 films due to the low vaporization temperature. Moreover, a metal-semiconductor-metal photodetector (PD) was fabricated and investigated systematically. We extracted an ultrahigh photoresponsivity approaching 101 A/W with concomitantly high external quantum efficiency up to 19,668% due to the produced gain arising from the holes trapped at the metal/MoSe2 interface, the band tail state contribution, and the photogating effect. A fast response time of 22 ms was observed and attributed to effective nonequilibrium carrier recombination. Additionally, the ultrahigh photoresponsivity and low dark current that originated from Schottky barrier resulted in a record-high specific detectivity of up to 2×1013 Jones for 2D MoSe2/MoS2 PDs. Our findings revealed a pathway for the development of high-performance PDs based on 2D MoSe2 that are inexpensive, large area, and suitable for mass production and contribute to a deep understanding of the photoconductivity mechanisms in atomically thin MoSe2. We anticipate that these results are generalizable to other layer semiconductors as well.

Authors: Šķiltere Daina , Bormane Santa
Published: October 2018

The problem of nowadays is that consumers lack information on food products, their composition and quality, nutritional value, packaging, its impact on the human health and environment, reuse and recycling possibilities, etc. Integrated marketing communications (IMC) as a business management tool may not only draw the consumers’ attention and incite a purchase, but also provide information and serve as a facilitator of consumers’ knowledge and competence on products, their nutritional value, use and utilisation. The goal of the research is to assess the impact of IMC for sustainability upon demand at Latvian food retail chains and the impact of the use of IMC for sustainability upon sustainable development. The object of the research is Latvian food retail chains, and the subject of the research is the use of IMC for sustainable development. The authors in 2017 surveyed leading specialists from food retail chains. The research confirmed the hypothesis that IMC for sustainability as an innovative business management tool fosters sustainable development. Based on the results of the research, the authors have drawn up a conceptual model of IMC for sustainable business development, and the results of the research are of both theoretical and practical value.

Published: October 2018

PEMFC needs to be maintained at an appropriate temperature and humidity in a rapidly changing environment for automobile applications. In this study, a pseudo-multi-dimensional dynamic model for predicting the heat and mass transfer performance of a plate-and-frame membrane humidifier for PEMFC vehicles is developed. Based on the developed model, the variations in the temperature and relative humidity at the dry air outlet are investigated according to the air flow acceleration. Moreover, the dynamic response is analyzed as a function of the amplitude and period of the sinusoidal air flow rate at actual operating conditions. The effects of heat transfer on the dynamic response are more dominant than those of mass transfer. The settling time of the temperature and relative humidity at the dry air outlet decrease with the increase in air flow acceleration. In addition, the variations in the temperature and relative humidity at the dry air outlet increase with the increases in the amplitude and period of the sinusoidal air flow rate.
Synchronität der Büromarktzyklen? Dynamiken europäischer Metropolen im Kontext der Finanz- und Wirtschaftskrise
Authors: Musil Robert , Reiner Christian
Published: October 2018

Urbane Büro-Immobilienmärkte sind durch eine zunehmende Internationalisierung gekennzeichnet und werden von Investoren als Anlagemöglichkeit zur Diversifikation ihrer Portfolios genutzt. Angesichts dieser Entwicklung wird in der Literatur die zunehmende Synchronisation der Büro-Immobilienmärkte diskutiert. Vor diesem Hintergrund untersucht der Artikel, ob auch die europäischen Büro-Immobilienmärkte durch eine Synchronisation der Zyklen gekennzeichnet sind. Darüber hinaus wird gefragt, in wie weit Büro-Immobilienmärkte mit nationalen Konjunkturzyklen zusammenhängen und ob es zu einer Konvergenz der Büro-Spitzenrenditen zwischen den europäischen Hauptstädten kommt. Auf Basis von empirischen Untersuchungen mittels parametrischer und nicht-parametrischer Korrelationsanalysen und Konvergenzanalysen kann für Europa eine – wenn auch sehr ungleiche – Tendenz zur Synchronisation festgestellt werden. Weiters zeigt sich, dass der Zusammenhang der Zyklen mit anderen Büromärkten aus dem gleichen Land deutlich höher ist, als der durchschnittliche Zusammenhang mit jenen aus anderen Ländern. Die Büromärkte folgen im Wesentlichen dem Muster der monetären europäischen Integration: Einer Konvergenz der Spitzenrenditen in der Frühphase der Euroeinführung folgt eine markante Divergenz beginnend mit der Wirtschaftskrise im Jahr 2008/2009.
Fatigue Behavior of Roller-Compacted Concrete Pavement Based on Full-Scale Fatigue Test
Authors: Park Jun Young , Lee Seung Woo , Han Seung Hwan , Kim Young Kyu
Published: October 2018

Roller-Compacted Concrete (RCC) has been used widely for construction of pavements. The strength of RCC Pavement (RCCP) can be obtained from not only hydration of binder but also the aggregate interlock resulting from roller compaction. For this reason, RCCP normally achieves strengths greater than conventional concrete pavement with similar cement content. Even though RCCP can provide good structural performance, it has been difficult to verify its long-term performance through actual field construction. Therefore, this study evaluated the fatigue behavior using 1 by 1-m dimensional RCC slab specimens obtained in the field in order to take into consideration field variability. A set of numerical analyses indicated that the failure modes of the specimens for a given loading condition appeared to be four-directional bottom-up cracks. A fatigue equation was developed based on the relationship between the stress level and the number of load repetitions.

Published: October 2018

In this article, the dynamic compressive behavior of asphalt concrete was investigated through the servo-hydraulic compressive test and Split Hopkinson Pressure Bar (SHPB) test. At a given temperature, asphalt concrete deformed slowly and permanently under quasi-static to low strain rate loading. Under higher strain rates loading, it suffered fracture. The failure plane of the asphalt concrete under low strain rates loading occurred at binder, while under high strain rates loading along the binder and aggregates. It was also found that the first branch of Dynamic Increase Factor (DIF) curve performed a smooth increase in strength, while the second branch increased sharply at the strain rate of 100 s−1. The suitability of the input DIF curve for numerical simulation was also discussed. A numerical model of asphalt concrete subjected to the SHPB test was developed and validated. It suggests the obtained compressive DIFs of asphalt concrete should be modified to avoid the duplication of the inertial effects. The modified DIF curve for current asphalt concrete material was also given. This research will be of direct importance to both practitioners and researchers involved with pavement design.

Authors: Qiu Shumao , Bai Mingzhou , Yu Ning , Shi Hai , Li Pengxiang
Published: October 2018

The influence of a single pile on its vertical uplift is tested, and a numerical calculation is conducted through a graded loading method. This study is aimed at investigating the influence of the pile side resistance on soil mass and analyzing the influence of the sensitivity of the soil and pile parameters to lateral resistance. Results show that the influence of the lateral resistance of the pile to the soil in forming silt clay is the first linear attenuation with horizontal distance trend. On the basis of the experiment, the concept of effect radius is presented. The change in pile body and soil parameters is beneficial to increasing the effect radius, thereby increasing the resistance of the pile side and influencing the mobilization range of the micropiles to the surrounding soil. Poisson’s ratio is the most sensitive to the change in the effect radius, followed by the change in the length of the pile. The sensitivity of the remaining parameters to the effect radius is from large to small.

Published: October 2018

The CCCTC-binding factor (CTCF) is a central regulator of chromatin topology recently linked to neurodevelopmental disorders such as intellectual disability, autism, and schizophrenia. The aim of this study was to identify novel roles of CTCF in the developing mouse brain. We provide evidence that CTCF is required for the expression of the LIM homeodomain factor LHX6 involved in fate determination of cortical interneurons (CINs) that originate in the medial ganglionic eminence (MGE). ConditionalCtcfablation in the MGE of mice of either sex leads to delayed tangential migration, abnormal distribution of CIN in the neocortex, a marked reduction of CINs expressing parvalbumin and somatostatin (Sst), and an increased number of MGE-derived cells expressingLhx8and other markers of basal forebrain projection neurons. Likewise,Ctcf-null MGE cells transplanted into the cortex of wild-type hosts generate fewer Sst-expressing CINs and exhibit lamination defects that are efficiently rescued upon reexpression of LHX6. Collectively, these data indicate that CTCF regulates the dichotomy betweenLhx6andLhx8to achieve correct specification and migration of MGE-derived CINs.

SIGNIFICANCE STATEMENTThis work provides evidence that CCCTC-binding factor (CTCF) controls an early fate decision point in the generation of cortical interneurons mediated at least in part by Lhx6. Importantly, the abnormalities described could reflect early molecular and cellular events that contribute to human neurological disorders previously linked to CTCF, including schizophrenia, autism, and intellectual disability.

Published: October 2018

The highly conserved DNA damage response (DDR) pathway monitors the genomic integrity of the cell and protects against genotoxic stresses. The apical kinases, Mec1 and Tel1 (ATR and ATM in human, respectively), initiate the DNA damage signaling cascade through the effector kinases, Rad53 and Chk1, to regulate a variety of cellular processes including cell cycle progression, DNA damage repair, chromatin remodeling, and transcription. The DDR also regulates other cellular pathways, but direct substrates and mechanisms are still lacking. Using a mass spectrometry-based phosphoproteomic screen in Saccharomyces cerevisiae, we identified novel targets of Rad53, many of which are proteins that are involved in RNA metabolism. Of the 33 novel substrates identified, we verified that 12 are directly phosphorylated by Rad53 in vitro: Xrn1, Gcd11, Rps7b, Ded1, Cho2, Pus1, Hst1, Srv2, Set3, Snu23, Alb1, and Scp160. We further characterized Xrn1, a highly conserved 5′ exoribonuclease that functions in RNA degradation and the most enriched in our phosphoproteomics screen. Phosphorylation of Xrn1 by Rad53 does not appear to affect Xrn1’s intrinsic nuclease activity in vitro, but may affect its activity or specificity in vivo.
Mejoramiento del rendimiento y precocidad del frijol (Phaseolus vulgaris L.)

Published: October 2018

Because of the complexity that yield components have, and the advantages that early varieties have for farmers considering actual yield components, genotype evaluation was initiated in 1985 to Identify early maturity types. At the same time, high yielding varieties were evaluated that were not necessarily early. The bulk selection method was used to advance to the F6 generation. Twenty rive populations from crosses among 10 parents with diverse maturities were evaluated. At F6, 458 individual .selections were made considering yield per plant, early maturity and visual characteristics. At F7 aprogeny test was made to evaluate F6 effectiveness Grain yields were reduced which is in part explained by the management given to the individual F6 selections compared to F7. Regarding early maturity, various were found with acceptable grain yields which are not common amongst early maturity varieties in the southeastern region of Guatemala (above 1-5 Mg/ha).

Published: October 2018

A basal mixture containing 35% soybean meal, 64.6% corn and 0.4 % methionine was used to formulate isocaloric and isoproteic diets for initiation, growth and finishing periods of development of native pigs, containing 16, 12 and 10% protein to be fed at8, 16 and 26 weeksof age, respectively. Lathyrus-used as the fiber source- was kept constant in the rations at levels of 16.4 and 32.8% for the three periods studied, reducing the content of the basal mixture in the diets on the basis of the protein contributed by the source of fiber added, and adding starch to maintain protein level constant. Information is presented on the digestibility of the nutrients of the diets for native pigs of 8 weeks of age on diets containing Ipomoea. Digestibility of cellular content decreased with fiber increment, although it improved at 26 weeks of age. Digestibility of acid detergent fiber, lignin and energy improved with age; nevertheless, they decreased between diets. Cellulose digestibility showed statistical differences among diets. Protein digestibility decreased with respect to fiber content, however, no significant differences were detected between age of animals and diets. Digestibility values between Lathyrus show significant differences in acid detergent fiber, lignin and cellulose in favor of Ipomoea.
Efecto de la escarificación química en la calidad de semilla de Centrosema spp. durante el almacenamiento
Authors: Búrbano Edgar A.
Published: October 2018

One of the most important forage legumes for acid and unfertile tropical soils is Centrosema spp. This genus is characterized by extremely hard seeds. Even with optimum conditions, because of its hard seeds, much does not germinate naturally. With this in mind, three species were selected, C. acutifolium, C. macrocarpum and C. brasilianum to evaluate the effect of chemical scarification on germination and emergence. Also, germination and emergence for these three entries were evaluated after having been stored for nineteen months at 18°C and 50 % relative humidity. Seed counts with and without scarification and the associated interaction with the defined treatments. The results indicated germination was lowered more with Centrosema acutifolium than the others when the described treatments were assessed (germination lowered by 40% after five months of storage). The other two species have harder seed which reflects the limited loss In germination observed (maximum of 10%). The emergence results from field trials were substantially different from germination data obtained in the laboratory (approximately 50%). These results indicate that seed stored under the two treatments for forage species such as Centrosema spp. Did not improve hardening significantly. The controlled conditions favored physiological qualities (germination) while maintaining hardness which was the case for C. macrocarpum. AWN scarified seed should not be stored under non controlled conditions as was noted for C. acutifolium which lost hardness rapidly and lacks defense mechanisms to avoid deterioration while stored. If scarification is employed a few days prior to seeding, adequate storage conditions should be employed.

Authors: Córdava Hugo
Published: October 2018

The uniform assay of the PCCMCA involves the evaluation of 30 coro hybrids in 20 contrasting environments in Latin America. The results from 1990 prove the consistency of response of come coro hybrids which have remaines in the first places during three years through 51 localities: HB-85, HB-83 and XH-53, with yields up to 6000 kg/ha (27% over the control). The stability parameters confirm the fitness of this response. New hybrids from private companies and national programmes show a continuous progress in plant breeding.

Published: October 2018

The main objective of this study was to manufacture instant products using whole and decerticated white sorghum (ISIAP-Dorado) with three different humidity contents (12, 15 and 18%). The protein, fat, fiber and ash contents were not affected by the process. The color of the extuded products from the decorticated sorghum showed higher values with respect to those of the whole sorghum. The viscosity properties, absorption indexes and water solubility of these products were modified, rendering them to new and varied uses. The density and degree of extrusion increased along with the increased humidity content of the flours, obtaining a larger extrusion and lower density for the products of decorticated sorghum. The palatability trial conducted with 50 persons showed no significant differences among treatments for the parameters of flavor, texture and overall appearance.

Published: October 2018

Several trials were conducted to evaluate the effectiveness of new insecticides in controlling the white fly Bemisia tabaci Genn, which is the vector of the Bean Golden Mosaic Virus (BGMV), at the Zapotitlan Valley and at the San Andres Experimental Station at 460 masl, during the dry season, from December 22, 1989 to May, 1990. A complete randomized block experimental design with 4 and 5 replications was used. Four trials were planted with the Rojo de Seda, Sangre de Toro and CENIA-Cuscatleco bean varieties. In the first and second trials, the chemicals bifentrin 100 EC (60 g.ai./ha) and fenpropatrin 375 EC ( 203 g.ai/ha) were efficient in controlling the whitefly, reducing the incidence of BGMV. If B. tabaci Genn is not controlled efficiently and timely, the BGMV incidence reaches 100% between 36 and 32 days after planting (DAP) on the susceptible varieties Rojo de Seda y Sangre de Toro. Seed and soil treatments combined with foliage spraying were also used in the third and fourth trials. The treatments of carbosulpan + bifentrin (1519.9 kg/ha) and acephate + bifentrin (1428 kg/ha) produced the highest yields with the resistent variety CENIA- Cuscatleco. Acephate + fenpropatrin (756.6 kg/ha), acephate + bifentrin (725.1 kg/ha) and carbofuran + fenpropatrin (636.3 g/ha) produced the highest yields with the susceptible variety Rojo de Seda. Of the tested products, fenpropatrin 375 EC showed the lowest populations of eggs and nymphs of B. tabaci Genn. There was a significant correlation between production and the time when the disease symptoms appeared. The largest Net Benefit was obtained with acephate 95% + bifentrin 100 EC treatment, followed by carbofuran 5% + bifentrin 100 EC.

Authors: Jacinto Hernández Carmen , Campos Escuerdo Albino
Published: October 2018

Seven bean varieties of the seed types: Flor de Mayo, Negro, Bayo, and Canario, and the line BAT 104 were included in this study. The objective of this research was to analyze the technological and nutritive characteristics as well as the changes that result from cooking in the digestibility and the activity of the trypsin inhibitor of the materials. Highly significant differences among varieties in weight, volume, coat percentage, cooking time, trypsin inhibitor activity and digestibility were found. The protein content in the materials ranged from 22.6 to 27.3 %. Also, differences were detected among materials in the chemical components such as starch, crude fiber, ash, lysine and tryptophan content. A low activity of the trypsin inhibitor in cooked beans was more correlated with longer cooking time and smaller grains rather than with the inhibitor content in raw beans. Digestibility of the materials was increased 11% on the average as a consequence of cooking.

Twenty eight inter-crosses from a diallel set of 8 Dominican inbred lines of maize were evaluated in 1990. The specific objectives were to determine general(gca) and specific (SCA) combining ability and to predict the best two and three-way hybrids. The inheritance of yield was determined by diaIlel analysis. General and specific (sca) combining ability and specific mean squares were statistically significant in yield, being the additive genetic variation much larger than the non additive variation. The parental T66 and NO3 showed the highest gca values and DK12xT66 (9.02 t/ha),NO2xNO3 (8.57t/ha) and DK12xT66 (8.36 t/ha) the best  sca values. The results partially agree with previous studies. The best three and two way hybrids predictions were (NO3xT66)x NO3 and(NO2xT66) (NO3xDK14) with grain yield of 8.80 and 8.30 t/ha.

Published: October 2018

The INIFAP (Instituto Nacional de Investigaciones Forestales y Agropecuarias) herbarium specimens of Phaseolus spp. collected in Mexico during the period from 1978 to 1991 were examined with the aim of increasing our knowledge on the distribution of the insects and diseases that attack those species. A total of 775 specimens, including 24 different Phaseolus species from different regions of Mexico, were studied. Based on visual symptoms of pathogen damage, a wide geographic distribution of diseases and insects was observed in almost all species; most of them are the same pathogens that attack the cultivated common bean (P. vulgaris). It is possible to find genetic resistance to pathogens in the wild Phaseolus spp., resistance that may be useful to improve the cultivated forms in the genus. However, the utilization of germplasm of wild Phaseolus species will depend upon the thorough characterization of those species, their compatibility with the cultivated beans, and the inheritance of the traits involved.

With the new Seed Law, the Free Trade Agreement, the high price ofhybrid seed and the large area with potential use of improved corn seed, the competence and participation of small seed companies has increased. The Department of Agricultural Engineering of the Universidad Autónoma de México (UNAM) is conducting plant breeding and research on seed technology and production since 1984. Some materials and populations from the Centro Internacional de Mejoramiento de Maíz y Trigo (CIMMYT), and lines from advanced generations of hybrids and local materials released by the UNAM were taken as a source of germplasm. Before combining the materials, a selection for stunting, bud elimination, lodging and disease tolerance was emphasized. The evaluation results show that the hybrids PUMA 1079, PUMA 1073, PUMA 1001 and PUMA 1003 surpass the most widely used hybrid in the High Valleys. Besides, they showed lower plant and ear height than the H-33. The PUMA hybrids are trilineal while the H-33 is a doublecross. The PUMA corns can be used by Small Seed Companies to favor a wideruse of certified seeds.

Published: October 2018

Objectives

Although rare, incidents of broken/dislodged fragment of various angioplasty hardwares, including catheters, guidewires, angioplasty balloons, and stents, are being increasingly reported in recent years. Since these broken fragments may cause life-threatening consequences for a patient, it is vital for an interventional cardiologist to be acquainted with different retrieval techniques. Here, we are reporting our observations of several incidents of device dislodgement/fracture during cardiac interventions and their retrieval using simple balloon method.

Methods

We present a study of eight patients in whom we attempted to retrieve dislodged/fractured cath-lab hardwares during cardiac interventions, using simple balloon method. These cases include two cases of balloon, three cases of stent, and three cases of guidewire dislodgement/fracture.

Results

Fractured/dislodged cath-lab hardwares were successfully retrieved using a simple balloon method in six out of eight cases (75%), without any need of other retrieval hardwares. We observed no major complications in any patient.

Conclusions

The balloon-assisted retrieval method is a simple, safe, and cost-effective way to avoid complications of endothelial injury, myocardial infarction, emergency coronary artery bypass graft, and sudden cardiac death. This study, particularly the context of retrieval technique used in each case, will offer valuable information to fellow interventional cardiologists.

J. A. da; FOLEGATTI, M. V.; CAMPECHE, L. F. de S. M.; SEASONAL VARIATION IN EVAPOTRANSPIRATION OF YOUNG ‘TAHITI’ACID LIME TREES  2 ABSTRACT             The objective of this study was to investigate seasonal variations in hourly and daily evapotranspiration (ETc) of acid lime ‘Tahiti’ trees under field conditions, defining values of crop coefficients. The study was carried out in Piracicaba, Brazil, during the winter of 2003 and the summer of 2004. Aweighing lysimeter of 2.7 mdiameter and 0.8 mdepth was planted with a two-year-old tree that was located at the center of an experimental area with 322 trees. The lysimeter tree was irrigated, like others in the plot, by four pressure compensated emitters. The average ETc was 1.50 mmday-1 in the summer and dropped to 0.66 mm day-1 in winter months. The average seasonal crop coefficient (Kc) was 0.36 and 0.22 for summer and winter, respectively. The maximum Etc time was at noon in the summer and at 2 pm in the winter. Moreover, night soil evaporation represented 17.4% and 13.4% of daily ETc in winter and summer. The soil evaporation curve  (Ke) in both seasons showed similar results.  KEYWORDS: citrus, lysimeter, crop coefficient, water requirements
Robin Sequence: Clearing Nosologic Confusion
Authors: Breugem C.C. , Courtemanche D.J.
Published: October 2018

Objective

To gather evidence surrounding the confusion in the classification of Robin sequence and inform those who have the power to make the changes in defining this symptom complex.

Method

A questionnaire was sent to all participating cleft palate teams (N = 204) of the American Cleft Palate–Craniofacial Association. The questionnaire identified the precise, different characteristics for diagnosing Robin sequence and evaluated whether the difference between a retrognathia and micrognathia influenced the diagnosis process. We subsequently also investigated whether the cleft type (i.e., U-shaped versus V-shaped) had any influence in the decision-making process. A PubMed literature review of the 50 most recent manuscripts about Robin sequence was evaluated also.

Results

Seventy-three questionnaires were received. This 35% response rate revealed 14 different definitions of Robin sequence. A PubMed literature review of 50 consecutive manuscripts revealed 15 different descriptions.

Conclusion

This study confirms that nosologic confusion is widespread with regard to defining Robin sequence. This has implications for evaluating Robin sequence, giving advice about the prognosis and genetic counseling, and refining treatment options.
Oral-Facial-Digital Syndrome Type 1: Oral Features in 12 Patients Submitted to Clinical and Radiographic Examination
Authors: Tagliani Marcela Martini , Gomide Marcia Ribeiro , Carrara Cleide Felício Carvalho
Published: October 2018

Objective

To evaluate the oral features in individuals with oral-facial-digital syndrome type 1 (OFD 1), previously diagnosed by the Genetic Sector of the Hospital of Rehabilitation of Craniofacial Anomalies of the University of São Paulo (HRAC-USP).

Design

Twelve patients with OFD 1 were examined clinically and radio-graphically; their medical files were also evaluated.

Results

Associated oral malformations were observed in all patients (100%). The most frequent findings were tongue hamartomas, multiple buccal frena, asymmetric lips, asymmetric tongue, and bilateral maxillary gingival swelling. Interestingly, atrophy of the maxillary midline frenum was also observed in all the individuals examined.

Conclusions

Several extra and intraoral alterations were observed in patients with OFD 1. The authors suggest the inclusion of atrophy of the maxillary midline frenum as a commonly found characteristic of OFD 1.
Speech Outcome following Late Primary Palate Repair
Authors: Murthy Jyotsna , Sendhilnathan Sunitha , Hussain Syed Altaf
Published: October 2018

Objective

Early palate repair is recommended to minimize the development of disordered speech. We studied the speech outcome of late palate repair in 131 patients. The success of late palate repair is questioned because of the persistence of learned, compensatory misarticulations that are difficult to correct in spite of the establishment of correct palatal anatomy and a competent velopharyngeal mechanism. The objective of this study is to highlight the speech results following late primary repair of the palate.

Settings and Design

Retrospective analysis of speech outcomes in 131 patients with cleft lip and palate who underwent primary palate repair after the age of 10 years between November 2000 and December 2004. None of the patients had received supervised institution-based speech therapy. However, all patients were counseled and oriented and demonstrated the correct place and manner of articulation for the phonemes misarticulated by them. Preoperative and 6- to 12-month postoperative speech samples were assessed within the parameters of articulation, hypernasality, nasal air emission, and speech intelligibility.

Outcome

The analysis indicated improvement in all speech parameters leading to an overall improvement in postoperative intelligibility for most patients.

Conclusion

Although definite improvement occurs in all parameters of speech following late primary palate repair, residual speech problems persist in most patients, requiring further evaluation and appropriate treatment.
Living with Moebius Syndrome: Adjustment, Social Competence, and Satisfaction with Life
Authors: Bogart Kathleen Rives , Matsumoto David
Published: October 2018

Context

Moebius syndrome is a rare congenital condition that results in bilateral facial paralysis. Several studies have reported social interaction and adjustment problems in people with Moebius syndrome and other facial movement disorders, presumably resulting from lack of facial expression.

Objective

To determine whether adults with Moebius syndrome experience increased anxiety and depression and/or decreased social competence and satisfaction with life compared with people without facial movement disorders.

Design

Internet-based quasi-experimental study with comparison group.

Participants

Thirty-seven adults with Moebius syndrome recruited through the United States–based Moebius Syndrome Foundation newsletter and Web site and 37 age- and gender-matched control participants recruited through a university participant database.

Measures

Anxiety and depression, social competence, satisfaction with life, ability to express emotion facially, and questions about Moebius syndrome symptoms.

Results

People with Moebius syndrome reported significantly lower social competence than the matched control group and normative data but did not differ significantly from the control group or norms in anxiety, depression, or satisfaction with life. In people with Moebius syndrome, degree of facial expression impairment was not significantly related to the adjustment variables.

Conclusions

Many people with Moebius syndrome are better adjusted than previous research suggests, despite their difficulties with social interaction. To enhance interaction, people with Moebius syndrome could compensate for the lack of facial expression with alternative expressive channels.
Prenatal Diagnosis of Craniomaxillofacial Malformations: A Characterization of Phenotypes in Trisomies 13, 18, and 21 by Ultrasound and Pathology
Authors: Ettema A.M. , Wenghoefer M. , Hansmann M. , Carels C.E.L. , Borstlap W.A. , Bergé S.J.
Published: October 2018

Objective

To determine the relationship between trisomies 13,18, and 21 and craniofacial malformations detected by prenatal sonography.

Design

During a 29-year period (1976 through 2004), prenatal sonographic findings of 69 fetuses with trisomy 13; 171 fetuses with trisomy 18; 302 fetuses with trisomy 21; and 17 fetuses with other trisomies were evaluated retrospectively, after fetal karyotype identification. Sonographic findings were compared with autopsy results in 209 patients (trisomy 13, n = 39; trisomy 18, n = 64; and trisomy 21, n = 106).

Results

For trisomy 13, cleft deformities were detected prenatally in 65.2%, and of the 39 cases with pathological information, 76.9% were found to have a cleft deformity. Ocular and orbital abnormalities were found in 28%. Malformations of the jaws and abnormal profiles were more frequently diagnosed postnatally than prenatally. For trisomy 18, abnormal profiles (41.5%) and ear abnormalities (5.3%) were the most noticeable ultrasound markers, next to abnormalities of the neurocranium (36.8%) and cranial bone configuration (21.6%). Dysmorphisms of the eye, ear, or nose were detected more frequently in autopsy cases. For trisomy 21, ultrasound showed an aberrant shape of the skull in 14.2% of fetuses. In general, the ocular-orbital and nasal abnormalities in fetuses with trisomy 18 or 21 were more evident in pathological examination than in prenatal ultrasound imaging.

Conclusions

Facial anomalies are common in the major trisomies, and their prenatal sonographic identification should be improved. The above-mentioned facial anomalies provide sufficient reason to consider performing cytogenic evaluation.

Published: October 2018

A 41-year-old man with cleft palate presented with a wide dehiscence and missing teeth. Six implants had been placed for fabrication of an overdenture, which was unsatisfactory. A bar was waxed and cast for connection to the implants; precision attachments were placed laterally for retention. A fixed partial denture was fabricated, and milled crowns were fabricated at the molar region to provide a guiding plane for insertion of a removable palatal obturator. Good swallowing and speech outcomes were achieved. This technique provided functional and esthetic benefits, enhanced oral hygiene, and improved the psychological condition of the patient.
Premaxillary Development in Normal and Cleft Lip and Palate Human Fetuses Using Three-Dimensional Computer Reconstruction
Authors: Mooney Mark P. , Siegel Michael I. , Kimes Kyle R. , Todhunter John
Published: October 2018

As part of an ongoing study of cleft lip and palate fetal morphology, premaxillary development was examined cross-sectionally in a sample of 20 ˵normal˶ fetuses and 9 fetuses with complete clefts of the lip and palate ranging in age from 8 to 21 weeks. The specimens were stained with H and E and sectioned at 20μm in the coronal plane. A computer reconstruction technique was used to produce three-dimensional images of the premaxilla. Premaxillary length and volume were quantified and used to produce fetal growth curves. Qualitatively, normal fetal specimens exhibited symmetrical premaxillary ontogenesis with development of the distinctive perinatal midfacial morphology noted by 14 weeks. In contrast, complete unilateral cleft specimens exhibited severe asymmetry and dysmorphogenesis through 20.5 weeks. Quantitatively, premaxillary length and volume values for the two samples were similar from 8 to 14 weeks and changed in a curvilinear fashion with the steepest Increases seen In normal specimens from 14 to 21 weeks. Cleft specimens exhibited significantly (p < 0.001) reduced premaxillary length and volume rate changes (i.e., slopes of regression lines generated from polynomial and logarithmic regression models) for this time period. Results suggest that premaxillary deficiencies noted clinically in cleft perinates may be related more to early prenatal midfacial growth deficits than initial mesenchymal tissue deficiencies or abnormal growth patterns.
Nasal Dermoid Sinus Cysts: Association with Intracranial Extension and Multiple Malformations
Authors: Wardinsky Terry D. , Pagon Roberta A. , Kropp Robert J. , Hayden Patricia W. , Clarren Sterling K.
Published: October 2018

Nasal dermoid and sinus cysts (NDSC) are uncommon congenital anomalies that may have intracranial extension and can be associated with other anomalies. We identified 22 patients in a retrospective review of cases diagnosed with NDSC at our institution over the past 10 years. Nine (41 percent) had associated anomalies and ten (45 percent) had intracranial extension of the sinus. In half of the patients with intracranial extension, the sinus traversed either the cribriform plate or foramen cecum and attached to the dura; in the other half, the sinus extended to cysts within the falx or other brain structures. Of the patients with multiple anomalies, six (67 percent) had intracranial extension. Presurgical complications occurred in a total of eight patients (36 percent): two had meningitis, two had osteomyelitis, four had periorbital-nasal cellulitis, three had nasal abscess, and four had nose anomalies requiring rhinoplasty.
The Branchio-Oculo-Facial Syndrome
Authors: Lin Angela E. , Losken H. Wolfgang , Jaffe Ronald , Biglan Albert W.
Published: October 2018

We review 13 reported cases and add the evaluations of 2 new patients with the branchio-oculo-facial (BOF) syndrome, a recently delineated autosomal dominant disorder with highly variable expression. This condition has a distinctive phenotype with characteristic craniofacial abnormalities consisting of aplastic or hemanglomatous cervical skin lesions with or without branchial sinuses; malformed, rotated auricles; and ocular abnormalities, which include microphthalmia or anophthalmia, coloboma, and cataract. The term pseudocleft has been used to describe the upper lip and philtrum abnormality found in mild cases, but the expression may extend to that of a complete cleft lip and palate. This unique disorder may go undetected In patients followed in cleft palate or craniofacial clinics and may not be recognized In patients with mild expressions. Genetic counseling for affected individuals is imperative because of the 50 percent recurrence risk. We emphasize the multidisciplinary care required to correct their craniofacial anomalies.
