ObjectiveEntamoeba spp. are globally distributed zoonotic parasites that infect various hosts, among which non-human primates (NHPs) have been identified as one of the most common hosts of these parasites. Consequently, the infections of Entamoeba spp. in captive NHPs from Nanjing Hongshan Forest Zoo in China were investigated in order to assess their zoonotic potential.MethodsA total of 120 fresh fecal samples, including 19 species of NHPs, were collected from four breeding bases of the zoo from May to June 2019. The infections of six species of Entamoeba spp. were detected by PCR using the 16S or 18S rDNA-specific primers, and the positive samples were sequenced and analyzed.ResultsEntamoeba spp. were detected as positive in 59 NHPs fecal samples (49.17%), including five Entamoeba species: Entamoeba histolytica (7.50%), E. dispar (22.50%), E. coli (22.50%), E. chattoni (10.00%) and E. nuttalli (1.67%). Infection with one Entamoeba species was more common (35%) than co-infections (13.33%) or infections with three Entamoeba species (0.83%). There was a significantly higher prevalence rate of Entamoeba spp. in the species Pongo pygmaeus and Macaca mulatta than in Papio sp., Mandrillus sphinx, and Saimiri sciureus.ConclusionEntamoeba spp. are highly prevalent in the NHPs raised in Nanjing Hongshan Forest Zoo. Therefore, attention should be paid to the development of containment strategies of Entamoeba spp. in this zoological garden.

Liver transplantation (LT) for patients with non-resectable colorectal liver metastases (CRLM) offers improved survival and has gained increased interest internationally the last years. The aim of this study was to describe the health-related quality of life (HRQoL) in patients with non-resectable CRLM receiving LT and how baseline HRQoL factors affect overall survival (OS). HRQoL data in the SECA (SEcondary CAncer) LT cohort was compared to data obtained from colorectal cancer patients starting first-line chemotherapy for metastatic disease in a clinical trial and data from a Norwegian normal population. HRQoL data from the QLQ-C30 questionnaire used in the SECA LT study and the NORDIC- VII study were reported. The relationship between patient-reported symptom burden at baseline and OS was investigated. In the SECA study longitudinal HRQoL assessment was used to describe the time until definitive deterioration as well as mean values at different time points. Patients in the SECA and NORDIC-VII studies reported similar baseline HRQoL. The median time until definitive deterioration in the transplanted patients was estimated to 36 months. In the SECA study appetite loss and pain at baseline had negative impact on OS (25.3 versus 71.7 months, p = 0.002 and 39.7 versus 71.7 months, p = 0.038, respectively). Despite a relapse in most of the LT patients the Global Health Score (GHS) remained good. Pain, and especially appetite loss at time of transplantation is associated with poor outcome after LT.

Published: May 2022

Crude oil price volatility impacts the global economy in general, as well as the economies of Europe and the United States in particular; it is supremely difficult to describe its tendency precisely, hence it leads to a forecasting methodology. This study aims to use the autoregressive integrated moving average (ARIMA), and seasonal autoregressive integrated moving average (SARIMA) approaches to cope with this problem in the United States and Europe. The data was gathered from the U.S. Energy Information Administration and federal research economic data (FRED) from January 2017 to September 2021. Simultaneously, values from January 2017 to March 2021, with 51 observations accounting for 90% of the total samples, were employed for the training phase, and the rest were used for the testing phase. The forecast result also indicated that the root mean square error (RMSE) and mean absolute percentage error (MAPE) values, applied by ARIMA models in Europe and the United States, have higher accurate indicators than SARIMA models. As a result, the ARIMA model achieved the best accuracy in both Europe and the USA, with MAPEEurope−ARIMA = 0.05, and MAPEUSA−ARIMA=0.05. Based on these accuracy parameters, the forecasting models appear incredibly reliable; similarly, the study results might assist governing bodies in making significant decisions, thereby accelerating socio-economic development in the world’s two largest economies.

The strengthening effect of a mild temperature treatment on the antimicrobial efficacy of essential oils has been widely reported, often leading to an underestimation or a misinterpretation of the product’s microbial status. In the present study, both a traditional culture-based method and Flow Cytometry (FCM) were applied to monitor the individual or combined effect of Origanum vulgare essential oil (OEO) and mild heat treatment on the culturability and viability of Escherichia coli in a conventional culture medium and in a fruit juice challenge test. The results obtained in the culture medium showed bacterial inactivation with an increasing treatment temperature (55 °C, 60 °C, 65 °C), highlighting an overestimation of the dead population using the culture-based method; in fact, when the FCM method was applied, the prevalence of injured bacterial cells in a viable but non-culturable (VBNC) state was observed. When commercial fruit juice with a pH of 3.8 and buffered at pH 7.0 was inoculated with E. coli ATCC 25922, a bactericidal action of OEO and a higher efficiency of the mild heat at 65 °C for 5′ combined with OEO were found. Overall, the combination of mild heat and OEO treatment represents a promising antimicrobial alternative to improve the safety of fruit juice.

Abstract
Time-resolved photoluminescence and capacitance-voltage measurement were performed on p-type GaN and InGaN films to study the minority carrier recombination mechanism. The minority carrier lifetime (τ
PL) for p-GaN with a Mg concentration of 1.7 × 1019 cm−3 was 46 ps. The non-radiative recombination due to gallium vacancies (V
Ga)-related defects is confirmed to dominate the minority carrier transport process. To suppress the formation of V
Ga defects, the indium atoms were added into p-GaN. As a consequence, the V
Ga-related non-radiative recombination centers were reduced from 8 × 1015 to 5 × 1014 cm−3 and a record long τ
PL of 793 ps was obtained for p-In0.035Ga0.95N film.
Enhancement of focusing properties of Bessel-like beam by metallic surface nanostructure
Authors: Chang Chin-Kai , Hsu Rui-Wen , Lin Ding-Zheng 
Published: May 2022

Abstract
The focusing properties of a Bessel-like beam emitted from a circular slit surrounded by a surface groove (CSSG) were explored using experimental and numerical methods. The optical properties of the light emitted from the CSSG can be enhanced by using the scattered light from the surface groove. Furthermore, different modes of cylindrical surface plasmons in the circular slit are induced by different wavelengths of incident light, and beam shapes with a single spot and doughnut are created under illumination in the ultraviolet and visible regimes, respectively. A versatile beam shape is obtained from the CSSG structure.
Assoggettabilità dei trust non liberali al tributo donativo
Authors: Tarini Federico 
Published: May 2022

Tesi
Nonostante la Corte di cassazione ritenga che i trust non liberali, seppur privi dello «spirito di liberalità» siano ancora soggetti al tributo donativo, questi devono, più correttamente, essere esclusi dal campo dell’applicazione dell’imposta in quanto caratterizzati da una componente esclusivamente a carattere oneroso.
The author’s view
Although the Supreme Court considers that non-liberal trusts, albeit lacking the «spirit of liberality», are still subject to the gift tax, these must, more correctly, be excluded from the scope of application of the tax as they are characterized by an exclusively onerous component.

Published: May 2022

На основе современных достижений по эффективному замещению в системах теплоснабжения ископаемых видов топлива на теплоту возобновляемых и вторичных источников предложена теплонасосная технология хлебобулочных изделий с использованием двухступенчатого парокомпрессионного теплового насоса. Установлены режимы функционирования теплового насоса, обеспечивающие подготовку теплоносителей разного температурного потенциала для энергоэффективной реализации технологического процесса. В соответствии с методологией эксергетического анализа рассмотрено влияние на технологическую систему производства хлебобулочных изделий внутренних и внешних энергетических потерь. В суммарное количество внутренних эк-сергетических потерь, связанных с необратимостью реальных процессов, входили потери от конечной разности температур в результате рекуперативного теплообмена между материальными и тепловыми потоками; электромеханические потери приводов машин; потери при необратимом изменении свойств промежуточных продуктов; гидравлические потери, обусловленные внезапным увеличением удельного объема теплоносителя при его поступлении из трубопровода в рабочие объемы аппаратов. Внешние потери связаны с условиями сопряжения системы с окружающей средой. Эксергетический анализ показал, что эксергетический КПД для тех-нологии получения хлебобулочных изделий с применением теплового насоса составляет 16,35 %, что на 5-7 % выше, чем у традиционных технологий. При переходе технологической системы в состояние равновесия с окружающей средой эта часть энергии полезным образом использована в термодинамических процессах предлагаемой технологии.

В статье рассматривается один из аспектов проблемы – лечение и профилактика сахарного диабета с использованием фитокомпозиции, составленной на базе растений отечественной флоры. Компоненты состава – растения, произрастающие в Таджикистане и имеющие надёжную сырьевую базу. А так как в последнее время вырос интерес к лечению сахарного диабета в связи с появлением коронавирусной инфекции и её последствиями, то актуальность данного фрагмента отчётливо выражена. И особенно привлекательно то обстоятельство, что исследуется с этой целью именно природный состав, который отличается также и новизной. Предлагаемый комплекс в форме сухих экстрактов проявил сахароснижающую активность. В связи с этим были выполнены фитохимические исследования в отношении полифенольного комплекса и витамина С, показавшие положительный результат. Данные исследования были проведены с использованием спектрофотометра. В качестве доминанты по фармакологическим показателям была выбрана солодка: при этом был определен тритерпеновый комплекс с преобладанием глицирризиновой кислоты, влияющий на антидиабетический эффект, который был апробирован и доказан, в свою очередь, на модели сахарного диабета. Оказалось, что содержание глицирризиновой кислоты в сухом экстракте, составляет 6,197 %. Таким образом, было подтверждено наличие в исследуемой фитокомпозиции, состоящей из сухих экстрактов солодки, галеги, липы, крапивы, мяты, шиповника, полифенольного комплекса и витамина С, а также отмечена значимая роль в этом комплексе солодки голой.

Indigofera spicata has been used by Kamba community of Kenya as an herbal medicine over a long period to treat coughs and toothaches. There is scanty information on the phytochemical compounds and the antimicrobial activity of Indigofera spicata plant extracts on Candida albicans, Streptococcus mutans and E. coli, which are known to cause many opportunistic infections to humans. This study aimed at investigating the phytochemical compounds and antimicrobial activity of Indigofera spicata leaves, roots and bark extracts against Candida albicans, Streptococcus mutans and E. coli. Plants were collected and plant parts dried separately and crushed to obtain a fine powder which was used to extract the crude extracts using methanol solvent. Plant samples were subjected to qualitative phytochemical tests for the identification of chemical constituents present using standard qualitative methods. Phytochemical constituents were analyzed by thin layer chromatography (TLC) in appropriate solvents (n-hexane and methanol, 3:1). The plates were observed under UV lamp at wavelength of 540nm, and Rf values were calculated for each spot. 5mm diameter paper discs were each dipped in a known concentration of the extracts of 0% (distilled water), 25%, 50% and 75% methanol extracts for 2 minutes and placed in either PDA or nutrient agar inoculated with the test organisms. Three discs were placed per petri dish and were incubated at 28 degrees and 48 hours for fungi and 37 degrees for 18-24 hours for bacteria. The experiment was arranged in a completely randomized design in the incubator. The growth diameter of inhibition was measured with a ruler. Data obtained on zone of inhibition was subjected to analysis of variance (ANOVA) by use of SAS statistical package. The methanolic extracts of the plants revealed the presence of tannins, sterols, alkaloids, saponins and terpenoids. However cardiac glycosides, phenols and flavonoids were absent in all the plant parts. Terpenoids were present in the stems and roots. Elution of the column with the n-hexane and methanol led to isolation of uncharacterized active compounds, three in leaves and stems, and two in roots. There were significant differences (p<0.05) between the extract concentrations, plant parts and the test microorganisms used. The leaves had the highest inhibitory effects at 75% methanol extract, i.e (5.7+0.2 mm, 6.8+0.2 mm and 8.3+0.7 mm growth diameter of Candida albicans, Streptococcus mutans and Escherichia coli respectively) compared to roots (5.7+0.2 mm, 6.0+0.3 mm and 7.0+0.3 mm growth diameter of Candida albicans, Streptococcus mutans and Escherichia coli respectively) and stem (5.8+0.2 mm, 5.3+0.2 mm and 7.7+0.2 mm growth diameter of Candida albicans, Streptococcus mutans and Escherichia coli respectively). The study suggests the potential of the plant as a source of new antimicrobial agents.

El propósito del estudio es evaluar la influencia de la Arrogancia, la Humildad y la Simpatía, rasgos relevantes y característicos en la cultura latinoamericana, sobre la salud mental; con el fin de enriquecer la teoría de rasgos universales de personalidad con un estudio transcultural. Se conformó una batería de auto-aplicación con las escalas de: Arrogancia, Humildad, Simpatía, Necesidad de Aprobación Social, los rasgos universales considerados en la escala IPIP, la subescala Honestidad/ Humildad de HEXACO y la escala de salud mental para evaluar Ansiedad y Depresión. Participaron voluntariamente 109 personas de Bolivia y 119 de México, seleccionadas por un muestreo no probabilístico porconveniencia. Los resultados mostraron que la necesidad de aprobación social (en su dimensión negativa) tiene una predicción significativa y negativa con Depresión y Ansiedad. La Arrogancia encontró una relación predictiva negativa con Depresión, mientras que Humildad y Simpatía tienen una relación predictiva negativa con Neuroticismo.
