Purpose: The correlation between the existence of the preoperative condition of ≥10 prism diopters (PD) in patients withbasic type of intermittent exotropia (IXT) and postoperative outcomes was analyzed. Methods: The medical records of patients that underwent surgery for IXT were analyzed retrospectively. The analysis wasconducted by dividing the patients into a group with change of <10 PD (group 1) and ≥10 PD (group 2) before the time of thesurgery. Patients who received at least 6 months of follow-up after surgery were included. The age, sex, angle of deviationand stereoacuity of the patients were studied. Surgical success was defined as exodeviation of <10 PD or esodeviation of <4PD at the final visit after the surgery. The correlation between clinical factors and surgical success rate was analyzed by usingcorrelative analysis. Results: A total of 129 patients participated in the study. There were 108 (83.7%) and 21 (16.3%) patients in groups 1 and 2,respectively. There were 89 (82.4%) and 17 (80.1%) patients with surgical successes in groups 1 and 2, respectively (p = 0.18). Moreover, 13 (12.0%) patients in group 1 and three (14.3%) patients in group 2 required reoperation, showing no significantdifference (p = 0.12). There was no statistically significant correlation between surgical success and preoperative change ofangle of deviation <10 PD (odds ratio, 1.78; p = 0.17). Conclusions: Among the patients with basic type of IXT subjected to the analysis, 16.3% had a change of ≥10 PD before surgery,and there was no significant correlation between surgical success and preoperative change of angle of deviation.

In previous experiment, drying efficiency of infrared and hot air dryers was investigated. On this study, drying rate of sweet potato according to different infrared interval was performed to find the optimal interval range. Steamed sweet potato was cut to a thickness of 0.5cm, the width and length were 1.5*3cm. The condition of infrared drying was 60 to 40°C, which range of interval was adjusted 5 to 20°C. Moisture content, brix, color, and texture were estimated as quality parameters. Drying rate was increased with decreasing temperature range and soluble solid contents were increased as drying time was increased, but there was no difference after 4 hours. Hardness was resulted in highest value at small temperature range and hard texture was affected by drying time. However, there were no significant differences in L, a, b value. In conclusion, small interval range of infrared was indicated highest drying efficiency and the optimal condition of drying time was 4 to 6.

PURPOSE. The accuracy of denture bases was compared among injection molding, milling, and rapid prototyping (RP) fabricating method. MATERIALS AND METHODS. The maxillary edentulous master cast was fabricated and round shaped four notches were formed. The cast was duplicated to ten casts and scanned. In the injection molding method, designed denture bases were milled from a wax block and fabricated using SR Ivocap injection system. Denture bases were milled from a pre-polymerized block in the milling method. In the RP method, denture bases were printed and post-cured. The intaglio surface of the base was scanned and surface matching software was used to measure inaccuracy. Measurements were performed between four notches and two points in the mid-palatal suture to evaluate inaccuracy. The palatine rugae resolution was evaluated. One-way analysis of variance was used for statistical analysis at α=.05. RESULTS. No statistically significant differences in distances among four notches (P>.05). The accuracy of the injection molding method was lower than those of the other methods in two points of the mid-palatal suture significantly (P<.05). The degree of palatine rugae resolution was significantly higher in the injection molding method than that in other methods (P<.05). CONCLUSION. The overall accuracy of the denture base is higher in milling and RP method than the injection molding method. The degree of fine reproducibility is higher in the injection molding method than the milling or RP method. [J Adv Prosthodont 2019;11:55-64] PURPOSE.

Background: An opportunistic intracellular pathogen Mycobacterium avium subsp. hominissuis, a member of the nontuberculous mycobacteria (NTM) cluster, causes respiratory disease in immunosuppressed hosts. In particular, infected companion dogs are a potential role to transmit the agent to children or immunosuppressed peoples. However, an underlying mechanism on the pathogeneses of M. avium hominissuis in dogs is not well known. Therefore, the purpose of this study is to investigate a host-M. avium hominissuis interactome in canine PBMCs and DH82 during the infection. Method: Peripheral blood mononuclear cells were isolated from six healthy beagles buffy coats by density gradient centrifugation. DH82 and PBMCs were stimulated in vitro with M. avium hominissuis strain 104. Total RNAs were extracted from the cells at 2h, 6h, 12h, and 24h after infection and gene expressions were quantified using real-time PCR. Results: M. avium hominissuis induces different gene expression in canine PBMCs and DH82. While PBMCs produced both M1 and M2-associated genes (TNF-α, IL-6, IL-1β, IFN-γ, IL-23, CXCL11, IDO1, IL-10, IL-4, IL-13, and CCL22), DH82 produced an M1-pattern of genes (IL-6 and TNF-α). In particular, M1-related genes expressed in canine PBMCs were increased until 6h after infection, on the other hand, M2-related genes were significantly up-regulated after 12 h infection. Conclusion: This result might reveal a specific interaction between M. avium hominissuis and the immune system in canine. As increasing interaction between human and companion animals, this study would contribute to prevent or treat M. avium subsp. hominissuis infection in dog and human.

Recently, additive-free sweet potato has been commercialized as a healthier snack food. However, these products are producing by semi-dried form to extend shelf-life, hence the products also possesses hard texture during chewing. To produce crispy sweet potato snack, this study was attempted to dry the semi-dried sweet potato instantly by a hot-press (HP) process. Mashed sweet potato was reformed and semi-dried at 65°C for varying time to provide various final moisture contents. The semi-dried samples were subjected to HP at the process temperature of 175-180°C for 2 seconds. As quality parameters, moisture content, brix, color, texture and sensorial test of the products were evaluated. Based on the results, optimal quality of the product was obtained by the semi-dried sample with 15~18% moisture at which the products exhibited good crispiness with bright yellow color. When the moisture content of the sample before HP was lower than 15%, the final products were normally broken during the HP process. In addition, extreme browning appearance was generated in this condition. Conversely, the sample with more than 18% of moisture was not completely dried by HP and the final product did not possess the crispy texture, although this product showed bright yellow appearance. Consequently, this study demonstrated the potential application of HP in sweet potato processing and the best condition was greatly affected by moisture content of sample prior to HP process.

<P>This study attempted to develop an additive-free dried sweet potato snack. To provide a crispy texture, sweet potatoes were dried by a two-stage process. At the first drying stage, steamed sweet potatoes were semi-dried for 6 h using hot-air convection or pulsed infra-red (IR) radiation, and drying rate was compared under varying sample thicknesses and drying temperatures. The IR exhibited enhanced drying speed, particularly the IR radiation at 60 degrees C was favorable for application to the drying of sweet potatoes with large thickness. For the secondary drying, the IR-dried sweet potatoes with varying moisture content were applied to hot-press (HP) drying at 180 degrees C for 2 s. The quality of final products indicated that the crispy texture of the products was generated when the semi-dried sample had a moisture content lower than 0.5 kg/kg dry base (d.b.). When the moisture content of samples prior to HP process was lower than 03 kg/kg d.b., the final product was easily broken with discoloration to dark-brown. Considering the entire processing procedure, the present study demonstrated that IR radiation at 60 degrees C for 5 h followed by HP was an effective combination for the mass production of a crispy sweet potato snack.

<P>Alzheimer’s disease is a neurodegenerative disease characterized by the impairment of cognitive function and loss of memory, affecting millions of individuals worldwide. With the dramatic increase in the prevalence of Alzheimer’s disease, it is expected to impose extensive public health and economic burden. However, this burden is particularly heavy on the caregivers of Alzheimer’s disease patients eliciting neuropsychiatric symptoms that include mood swings, hallucinations, and depression. Interestingly, these neuropsychiatric symptoms are shared across symptoms of bipolar disorder, schizophrenia, and major depression disorder. Despite the similarities in symptomatology, comorbidities of Alzheimer’s disease and these neuropsychiatric disorders have not been studied in the Alzheimer’s disease model. Here, we explore the comprehensive changes in gene expression of genes that are associated with bipolar disorder, schizophrenia, and major depression disorder through the microarray of an Alzheimer’s disease animal model, the forebrain specific PSEN double knockout mouse. To analyze the genes related with these three neuropsychiatric disorders within the scope of our microarray data, we used selected 1207 of a total of 45,037 genes that satisfied our selection criteria. These genes were selected on the basis of 14 Gene Ontology terms significantly relevant with the three disorders which were identified by previous research conducted by the Psychiatric Genomics Consortium. Our study revealed that the forebrain specific deletion of Alzheimer’s disease genes can significantly alter neuropsychiatric disorder associated genes. Most importantly, most of these significantly altered genes were found to be involved with schizophrenia. Taken together, we suggest that the synaptic dysfunction by mutation of Alzheimer’s disease genes can lead to the manifestation of not only memory loss and impairments in cognition, but also neuropsychiatric symptoms.</P>
