Furthermore, even when accounting for the reduced levels of parasitism observed in resistant cultivars, projected population growth rates for C. cinctus were always lower in resistant compared with susceptible wheat cultivars. CONCLUSION Despite some empirical evidence for antagonistic interactions between resistance and biological control, our models suggest that combining these two approaches will always reduce population growth rates to lower levels than implementing either strategy alone. More work focused on integrating biological control into crop resistance breeding programs, and determining how these approaches affect performance of limiting life stages, will be important to optimize sustainable approaches to integrated pest management in this system and more broadly.

Nevertheless, essential oil composition from these species is still little known. This work aimed the analysis of essential oils obtained from different Brazilian Celastraceae species. A total of seventeen oils were obtained using hydrodistillation process and analyzed by gas chromatography/mass spectrometry (GC/MS). Principal component analysis (PCA) allowed the identification of a chemical composition pattern among the analyzed essential oils. Some compounds were more frequent among Celastraceae species, such as cis and trans -oxide linalool (14/17 oil samples), nerylacetone (13/17), linalool (11/17), β -ionone (10/17), α -ionone (9/17), nerolidol (10/17), decanal (10/17) and dodecanoic acid (10/17). These results contribute to the chemophenetics of Celastraceae species. © 2020 WILEY-VCH Verlag GmbH & Co.

This study aimed to show the experiences and challenges of an HLA laboratory in the validation process of the NGS methodology for HLA typing and demonstrate the use of this method for the study of HLA genetic diversity. METHODS We used 115 samples that comprised a comprehensive testing panel for validation of the NGS methodology using the AllType kit (One Lambda, USA) on the Ion Torrent S5 NGS platform. All quality metrics were analyzed. During validation, two new HLA sequences were identified and named by the HLA Nomenclature Committee. RESULTS A total of 1380 alleles from the HLA-A, -B, -C, -DRB1, -DQB1, -DPB1 loci were examined by NGS. This validation panel provided a wide range of HLA sequence variations, including non-CWD HLA alleles, new variants, and homozygous alleles. The concordance rate with Sanger sequencing-based typing was 100.0% for HLA-A, -B, -C, -DRB1, -DQB1 and 99.93% for HLA-DPB1. The newly identified HLA alleles were HLA-B*1469 N and HLA-DQB1*02145. CONCLUSION We have successfully validated NGS HLA typing despite numerous challenges, contributing to the identification of novel alleles that impact on HLA matching and antibody evaluation in organ and tissue transplantation.

There are currently no reproducible simulation models to train this clinical procedure. The purpose of this study was the design, feasibility and evaluation of a 3D printed tooth model for the preclinical teaching of students. MATERIALS AND METHODS A printable tooth was designed and printed by a stereolithographic printer. 48 fourth-year dental students in the first clinical course in prosthodontics were trained in a voluntary hands-on course on 4 similar printed teeth. The students used standard model teeth and real-teeth-models during their education. They had experience in caries removement and root canal treatment on real patients. Selleck SB-297006 Root perforations were counted for every attempt. The different benefits of the 3D printed tooth were evaluated by a questionnaire using german school grades from 1 (best) to 6 (worst). RESULTS The overall rating of the printed tooth was 1.9 ± 0.3. The item "suitable exercise option" was rated 2.0 ± 0.8 and the teeth were "easy to use" 1.9 ± 0.9. The item "realistic approach to dentin post preparation" was rated 2.1 ± 0.8 and the teeth showed the "shortcomings at a root perforation" 1.5 ± 0.6. The students reported to have much more motivation and enthusiasm to improve their skills with the printed teeth 2.1 ± 0.9. They had a strong desire to include these teeth in their preclinical education before the first patient treatment 1.6 ± 0.8. The success rate of the dentin post preparation was significant better for the second 25% (p = 0.047) and fourth 48% (p = 0.04) attempt. CONCLUSIONS The feasibility of this teaching concept was confirmed. The students had the possibility to learn a correct dentin post preparation on a printed tooth model. The learning effect with this tooth model was rated as good to very good by the questionnaire. This article is protected by copyright.

Consequently, the population is highly uniform and has limited human leukocyte antigen (HLA) diversity relative to people from other countries. However, Japan has three ethnolinguistic groups, and HLA distributions differ depending on geographic region. To collect an HLA-rich variety of bone marrow bank donor registrants, it is essential to know the precise distribution of HLA in Japan. We analyzed HLA alleles and haplotypes based on HLA information of 177 041 bone marrow donor registrants. Registrants were grouped depending on the prefecture and region (a group of prefectures) as commonly used in Japan. The prefectures did not show the same distributions, but the tendency was similar for each region. We found that Okinawa Prefecture and the mainland can be clearly divided as haplotypes [A*2402-C*0102-B*5401-DRB1*0405] and [A*2402-C*0102-B*5901-DRB1*0405] were typically found in Okinawa (p = 0.
