    New larval hosts are presented for 152 North American Cerambycidae (Coleoptera). Larval host plants of Aneflus calvatus Horn in Leng, Aneflomorpha arizonica Linsley, Aneflomorpha fisheri Linsley, Ane­flomorpha opacicornis Linsley, Anelaphus magnipunctatus (Knull), Atylostagma glabra Schaeffer, Cacophrissus pauper Bates, Elytroleptus limpianus Skiles and Chemsak, Obrium rubidum LeConte, and Stenelytrana splen­dens (Knull) are reported for the first time. The types of wood utilized by larvae of Leptorhabdium pictum (Haldeman), Sphenostethus taslei (Buquet), Typocerus lugubris (Say), and Xestoleptura octonotata (Say) are discussed. Notes on larval morphology and larval habits of Aneflus spp. and Stenaspis solitaria (Say), includ­ing a correction of a published host plant record for S. solitaria, are provided. Urgleptes sandersoni Gilmour is reported from the United States (Florida) for the first time. The family Cerambycidae is a diverse group of wood boring beetles with over 1000 species in North America alone and tens of thousands worldwide. Host plant associations for North American Cerambycidae have been summarized by Linsley and Chemsak (1997) and many subsequent papers have provided additional information (Swift 2008; Vlasak 2014; Heffern et al. 2018; Maier 2018; Maier 2020 and references therein). Several recent publications attempted to correct erroneous records in the literature and highlighted some questionable ones (Bousquet et al. 2018; Heffern et al. 2018; Maier 2018; Maier 2020). Nevertheless, the biology of about 180 North American species remains unknown and the understanding of host plant associations overall is incomplete. This work is a continuation of efforts to further the knowledge of the natural history of Cerambycidae. Only host plants not previously reported in the literature (summarized in Table 1) are presented unless stated otherwise. Plant taxonomy follows that of Kartesz (2015)

    Juan Amós Comenio, perfil de un filósofo

    Jan Patočka ingresó a la comeniología, en 1941, con un artículo programático titulado Una nueva mirada a Comenio[1]. El título de este artículo es la expresión prístina de lo que Patočka trató en los siguientes treinta años, a lo largo de su carrera científica. Patočka reconoce en su texto a los representantes más destacados de la comeniología del momento; sin embargo, cree que “otro, un nuevo Comenio, se necesita hoy”, que no sería sólo una decocción de comida literaria masticad

    Histone deacetylase inhibitors (HDI) dampen cellular innate immune response by decreasing interferon production and have been shown to increase the growth of vesicular stomatitis virus and HSV. As attenuated tumour-selective oncolytic vaccinia viruses (VV) are already undergoing clinical evaluation, the goal of this study is to determine whether HDI can also enhance the potency of these poxviruses in infection-resistant cancer cell lines. Multiple HDIs were tested and Trichostatin A (TSA) was found to potently enhance the spread and replication of a tumour selective vaccinia virus in several infection-resistant cancer cell lines. TSA significantly decreased the number of lung metastases in a syngeneic B16F10LacZ lung metastasis model yet did not increase the replication of vaccinia in normal tissues. The combination of TSA and VV increased survival of mice harbouring human HCT116 colon tumour xenografts as compared to mice treated with either agent alone. We conclude that TSA can selectively and effectively enhance the replication and spread of oncolytic vaccinia virus in cancer cells

    Factor Validity and Generic Reliability of the Developmental Coordination Disorder Questionnaire in the Czech Population

    The Developmental Coordination Disorder Questionnaire (DCDQ) is widely used as a brief parent questionnaire designed to screen for motor coordination in children, aged 5 to 15 years. There is no validated version of the DCDQ for the Central Europe, which could help for first catch of children with motor difficulties, whose amount has been seriously raised. In addition, the World Health Organization recommends the cross-cultural validation of existing instruments, for Loir costs and time consuming, and the availability of instruments in several languages enables therapists to use validated tools with non-English speaking clients. The aim of this study was to validate the DCDQ in the Czech culture in a population of Czech parents whose children were aged six to ten. Using data from 651 Czech parents of children (six to ten years; 7.8 ± 0.8 years), confirmatory factor analyses (CFA) were used. The goodness-of-fit indices CFI = 0.94, TLI = 0.93, and RMSEA = 0.08 supported the original three-factor model of the DCDQ. In addition, the factor loadings of each question discovered in Czech DCDQ were non-significantly different from the original DCDQ. Furthermore, we also found strong between factor correlation; general coordination and control movement r = 0.87 probably measure the same underlying construct. Even though this is in conformity with original DCDQ structure, we suggest that responses in these two DCDQ factors might have violated the local independency and, therefore, could bias the final score. The generic reliability of the individual factors was acceptable and ranged from McDonald ω 0.83–0.88. Results from this study suggest that cross-validated version of the original DCDQ can be considered as sufficiently valid and reliable clinical screening tool for children who have coordination challenges for Czech children aged six to ten

    BackgroundToday’s diabetes-oriented telemedicine systems can gather and analyze many parameters like blood glucose levels, carbohydrate intake, insulin doses, and physical activity levels (steps). Information collected can be presented to patients in a variety of graphical outputs. Despite the availability of several technical means, a large percentage of patients do not reach the goals established in their diabetes treatment. ObjectiveThe objective of the study was to evaluate the benefits of the Diani telemedicine system for the treatment of patients with type 1 diabetes mellitus. MethodsData were collected during a 24-week feasibility study. Patients responded to the World Health Organization Quality of Life – BREF (WHOQOL-BREF) questionnaire and a system evaluation questionnaire. The level of glycated hemoglobin (HbA1c) and the patient’s body weight were measured, and the patient’s use of the telemedicine system and their daily physical activity level were monitored. All data were sent from the patient’s device to the Diani server using a real-time diabetes diary app. Wilcoxon and Friedman tests and the linear mixed effects method were used for data analysis. ResultsThis study involved 10 patients (men: n=5; women: n=5), with a mean age of 47.7 (SD 19.3) years, a mean duration of diabetes of 10.5 (SD 8.6) years, and a mean HbA1c value of 59.5 (SD 6.7) mmol/mol. The median number of days the patients used the system was 84. After the intervention, the mean HbA1c decreased by 4.35 mmol/mol (P=.01). The patients spent 18.6 (SD 6.8) minutes on average using the app daily. After the intervention, the number of patients who measured their blood glucose level at least 3 times a day increased by 30%. The graphical visualization of the monitored parameters, automatic transmission of measured data from the glucometer, compatibility, and interconnection of individual devices when entering data were positively evaluated by patients. ConclusionsThe Diani system was found to be beneficial for patients with type 1 diabetes mellitus in terms of managing their disease. Patients perceived it positively; it strengthened their knowledge of diabetes and their understanding of the influences of the measured values on the management of their disease. Its use had a positive effect on the HbA1c level
