Strategie działalności innowacyjnej w grupach kapitałowych
Authors: Romanowska Maria , Melnarowicz Krzysztof
Published: July 2020

Przedmiotem publikacji są strategie prowadzenia działalności innowacyjnej w grupach kapitałowych i potrzeby informacyjne związane z formułowaniem i realizacją tych strategii. Wyróżniono trzy modelowe strategie prowadzenia działalności innowacyjnej w grupach: skoncentrowaną, rozproszoną synergiczną i rozproszoną niesynergiczną, przypisując każdą z modelowych strategii do określonego typu grup kapitałowych. Przyjęto założenie, że strategie prowadzenia działalności innowacyjnej w różnego typu grupach kapitałowych wymagają różnych podstaw informacyjnych decyzji o zarządzaniu działalnością innowacyjną grupy i dostosowania do tych potrzeb metod diagnostycznych. Dla analizy potrzeb informacyjnych zastosowano autorski model doskonałości innowacyjnej przedsiębiorstwa oraz badanie potrzeb wsparcia spółek podrzędnych w grupie kapitałowej za pomocą wywiadów i ankiet. Autorzy, wykorzystując wyniki badań związane z realizacją ekspertyzy dla właściciela Grupy Alfa, przedstawili metodykę przygotowania podstawy informacyjnej dla decyzji o wsparciu finansowym działalności innowacyjnej spółek podrzędnych w grupie finansowej pokrewnej. Ze zbioru kilkudziesięciu spółek Grupy Alfa wyselekcjonowali 24 spółki mające dostateczny potencjał absorpcji środków wsparcia, równocześnie wskazując na zróżnicowanie tego potencjału i konieczność różnicowania polityki wsparcia w zależności od tego, czy spółka należała do typu „lokomotywa innowacyjności”, „potencjalny innowator” czy „okazjonalny innowator”. Dodatkowo dzięki zbadaniu motywacji, uwarunkowań działania i potrzeb oczekiwań spółek wskazano na preferowane przez nich sposoby wsparcia. Zastosowana w badaniach ekspertów metoda badania zdolności absorpcyjnej spółek za i ich potrzeb w zakresie wsparcia okazała się prostym i trafnym narzędziem zbudowania podstawy informacyjnej do podjęcia decyzji zarządu Grupy w zakresie wsparcia spółek Grupy w ich działalności innowacyjnej. Wydaje się, że procedura badawcza zaprezentowana w artykule może być wykorzystana w szerszym zakresie w budowaniu strategii wspierania innowacyjności spółek w grupie kapitałowej.

FIFTY YEARS OF RYEGRASS RESEARCH IN NEW ZEALAND
Authors: Hunt W.F. , Easton H.S.
Published: July 2020

Ryegrasses have dominated seed mixtures since the inception of pastoral farming in New Zealand largely because perennial ryegrasses are easily established, and persistent under a wide range of climatic and management conditions. Annual ryegrasses have vigorous seedling growth and can provide valuable high quality feed during the cool seasons. These virtues make ryegrass easily thk most important grass in New Zealand agriculture. This review traces the history of ryegrass use and development form the early days of bush burn mixtures to the present day array of bred cultivars Areas of research covered in the review include: (1) The selection and breeding of cultivars (2) Management effects on density and persistence (3) Physiology (responses to light, temperature and mineral nutrition) (4) Ryegrass diseases (5) Ryegrass pests (6) The ryegrass endophyte (7) Ryegrass herbage quality The concluding section examines the role ryegrasses are to play in diverse modern agricultural systems, and hence the goals for breeders.
A REVIEW OF 10 YEARS' RESEARCH WITH RED CLOVERS UNDER GRAZING IN SOUTHLAND
Authors: Hay R.J.M. , Ryan D.L.
Published: July 2020

In a series of trials at Grasslands Gore, over 10 years, the late-flowering tetraploid red clover 'Grassland Pawera' was more productive and persistent than other red clover cultivars. The strong summer growth of Pawera meets the need for heavy-weight lamb feed and high quality forage for conservation in intensive sheep farming systems in Southland. Lenient. infrequent defoliation is necessary to maximise DM production and persistence of Pawera. The most compatible of the grasses evaluated was 'Grasslands Roa' tall fescue. However, 'Grasslands Nui' ryegrass will still be the major grass sown with Pawera owing to its widespread acceptance. In ryegrass mixtures, sowing rates of 5-7 kg/ha of red clover were needed to optimise establishment and subsequent yield. Evidence of oestrogenic activity of Pewera to sheep prompted Grasslands Division to select within Pawera for a low formononetin cultivar. Keywords: red clover, Pawera. Hamua, Turoa. G21. G22, G27. oestrogenic activity, Nui ryegrass, Roa tall fescue, Maru phalaris. Southland, sheep grazing, frequency, intensity, quality. seasonal growth
An on-farm evaluation of white and subterranean clovers in North Island hill country
Authors: Macfarlane M.J. , Mcgowan A.W. , Sheath G.W. , Korte C.J.
Published: July 2020

Five white clover and 5 subterranean clover cultivars were evaluated under 'on-farm' conditions at 21 North Island sites over 5 years. Seedlings were established in the field and their content in the sward followed by point analysis. Grasslands Huia, Grasslands Tahora and Whatawhata Early Flowering established most rapidly. Overall, white clover was not altered by the introduction of any cultivar into existing pastures. White clover content of the sward appear to be determined by factors other than genetic potential, such as other species present, current management practices, and climate. All subterranean clover cultivars established populations, though Tallarook was the most successful. At most sites Tallarook regenerated the best, followed by Mt Barker. The contribution to legume density made by any other subterranean clover cultivar was minimal Keywords white clover, subterranean clover, hill country, point analysis
Effect of superphosphate, lime, and cocksfoot on summer dry hill country pasture production
Authors: Mackay A.D. , Tillmanz R.W. , Parker W.J. , Barker D.J.
Published: July 2020

Two long-term field trials were carried out in the Wairarapa. One, established on a resident ryegrass/browntop pasture in 1981, compared the effect of lime (0, 1.25, 2.50 and 5.00 t/ha) and superphosphate (0,125,250 and 500 kg/ha) in a 4 x 4 factorial design. The second, started in 1985, compared the response of a similar pasture with that of au oversowu 'Grasslands Wana' cocksfoot pasture to 4 rates of lime (0, 1.25, 2.5 and 5.0 t/ha). The major effect of the traditional fertiliser policy was increased spring and, under favourable conditions, increased summer and autumn production. The introduction of cocksfoot guaranteed a more predictable summer supply of feed and improved autumn and winter production. An assessment of 3 methods of designating fertiliser expenditure suggests that continuation with maintenance fertiliser inputs, or a 2.3: 1 substitution of fertiliser expenditure for cocksfoot establishment, would provide greater benefits than discontinuing fertiliser inputs.

Effect of intensity and frequency of defoliation on growth of ryegrass, tall fescue and phalaris
Authors: Kerrisk J.J. , Thomson N.A.
Published: July 2020

Pasture growth rates of ryegrass, tall fescue and phalaris were compared under combinations of 2 defoliation heights and 3 defoliation frequencies in mowing trials run in spring, summer, autumn and winter over 2 years. Lax defoliation gave on average 15%, 20% and 21% higher pasture growth rates than intense defoliation for ryegrass, tall fescue and phalaris pastures respectively over all seasons. Climate had a major influence on the response of all three pastures to defoliation management. In a dry spring, tall fescue produced most from a 15day cutting interval while for ryegrass and phalaris production was greatest from a 30day interval. In a wet spring, cutting frequency had no etfect, but a significant (P
Effect of Microstructure Control on the Mechanical Properties of Hot Worked TiAl Alloy
Authors: Kim Jong-hun , Kim Jae-Kwon , Kim Seong-Woong , Park Yong-Ho , Kim Seung Eon
Published: July 2020

The microstructure and mechanical properties of a newly developed, β-phase containing TiAl alloy have been studied through hot working and post heat treatment to enhance room temperature ductility and strength. The controlled microstructures hadthree types of structure, fully lamellar, nearly lamellar and duplex, and were produced by cyclic heat-treatment in a single α region and (α+γ) region after a hot-forging process in high temperature (α+β) region. As a result of the room temperature tensile test, the fully lamellar structure exhibited a tensile strength of 622 MPa and ductility of 0.62%. The duplex structure had a tensile strength of 787 MPa and ductility of 1.22%, while the nearly lamellar structure showed a tensile strength of 880 MPa and ductility of 1.76%. In the room temperature tensile test, the nearly lamellar structure exhibited excellent tensile strength and ductility. The strength and ductility were increased by decreasing grain size and β / B2 phase fraction. The newly developed TiAl alloy showed higher tensile values compared with the previous TiAl alloys. The relationship between microstructure and room temperature tensile properties of the newly developed β-phase containing TiAl alloy was examined, and the best approach for hot working and post heat-treatment to obtain the most balanced mechanical properties was proposed.
Effect of Co Leaching on the Vertical Turning Lathe Wear Properties of Polycrystalline Diamond Compact Manufactured by High Temperature and High Pressure Sintering Process
Authors: Baek Min-Seok , Kim Ji-Won , Park Bae-Gun , Park Hee-Sub , Lee Kee-Ahn
Published: July 2020

Polycrystalline diamond compact (PDC) has excellent wear resistance, high impact resistance, superior fatigue properties, and has been used in the oil and gas drilling industries. This study investigated the effect of Co leaching on the microstructure, vertical turning lathe (VTL) wear properties of PDCs manufactured by high-temperature and high-pressure (HTHP) sintering. The VTL wear test has the advantage of simulating the actual oil drilling environment by using granite as the workpiece. PDC sintered material that did not receive Co leaching was named HTHP sintered PDC-A, and the material subjected to Co leaching was called Co-leached PDC-B in this study. As a result of XRD analysis of both PDCs, diamond and WC peaks were detected, and only the HTHP sintered PDC-A exhibited some Co peaks. In the HTHP sintered PDC-A, the binder WC and Co were evenly distributed at the diamond interface. However, in the Co-leached PDC-B, some empty spaces were observed at the diamond interface. The HTHP sintered PDCA exhibited a similar or slightly higher VTL wear resistance than the Co-leached PDC-B, but only in the short sliding distance. In the long sliding distance after 9 km, Co-leached PDC-B showed significantly superior wear resistance compared to the HTHP sintered PDC-A. The HTHP sintered PDC-A exhibited both abrasive and adhesive wear behaviors, while the Co-leached PDC-B showed only abrasive wear. Based on the above results, the VTL wear mechanism of PDCs, and ways of improving wear resistance were also discussed.
Correlations Between Alkali and Crystallinity in lyocell-Based ACF Probed with X-Ray Diffraction
Authors: Jin Young Min , Lee Joon Hyuk , Choi Sang Sun
Published: July 2020

This study examined the effect of alkalis on lyocell-based activated carbon fibres (ACFs) with high Brunauer-Emmett-Teller (BET) surface areas, using X-ray diffraction (XRD). Here, alkali treatments were conducted using 10 ~ 25 % NaOH and KOH on lyocell samples for 3 h at ambient room temperature. A secondary treatment with 4 % each of KOH and H3PO4 for an additional 3 h followed. An activated form of the samples was prepared by oxidation (stabilisation), carbonisation, and activation. The final ACF form of the samples showed a porous structure with high BET surface areas (> 1,000 m2 g-1). A 25 % dosage of NaOH produced the highest BET surface area compared to other samples. In terms of crystallinity, a 15 % dosage of KOH was found to be the optimum dosage to secure the highest degree of crystallinity among all samples. Meanwhile, the NaOH was successfully shifted the samples into the most distinct form of cellulose II. 15 % NaOH was found to secure the most stable thermal characteristics, as determined via thermo-gravimetric analysis. The present work demonstrates the various physio-chemistries of ACFs prepared with different proportions and types of alkalis, leading to intriguing potential applications.
21st Century neo-androgyny: A measure of de-gendered androgyny.
Authors: Tannett Bobbi , Samuels Curtis
Published: July 2020

The last 45 years of gender research into the benefits of psychological androgyny have resulted in a mélange of results and the picture for androgyny has not always clearly emerged as positive. One is required to ask whether or not the construct of androgyny as some mystical combination of masculine and feminine characteristics is any longer theoretically defensible. The study of sex and gender should perhaps be charged with offering a new theoretical framework from which a coherent, consistent, and lasting concept of androgyny may be derived, and from which the androgyny hypothesis may be re-examined and perhaps reborn.

Authors: Castillo-Girón Víctor-Manuel , Machuca-Martínez Manuel , Ayala-Ramírez Suhey
Published: July 2020

Si bien antes de los años 1990 ya había participación de grandes empresas minoristas en México, la llegada de empresas transnacionales, como Wal-Mart, generó una reconfiguración en la distribución de alimentos y, con ello, una expectativa del impacto directo sobre algunas variables del sector. Nuestro objetivo es determinar si la presencia de Wal-Mart implica cambios en el rendimiento total de los factores de producción. Para ello se construyó un modelo de regresión de corte transversal, cuyos resultados a escala municipal muestran nulo impacto sobre las unidades económicas pertenecientes a los abarrotes y restaurantes, en tanto que para autoservicios y farmacias se estima una reducción de los rendimientos de los factores de producción dada la presencia de dicha empresa.
Impacto macroeconómico del cóvid-19 en Puerto Rico: un enfoque de equilibrio general dinámico y estocástico
Authors: Rodríguez Carlos A. , Alemar Emanuelle A.
Published: July 2020

Este trabajo evalúa el potencial impacto dinámico del cóvid-19 en Puerto Rico desde la perspectiva del costo indirecto de la enfermedad. Con estos fines, se calibra un modelo de equilibrio general dinámico y estocástico, al cual se le introduce un choque epidémico desarrollado por Torój (2013). Los efectos macroeconómicos de este choque son simulados cuando la enfermedad se propaga de manera anticipada y no anticipada. Los resultados de la simulación indican que la contracción en la producción agregada puede fluctuar entre 1.8% y 5.4% como consecuencia de la propagación del virus. De no contenerse el virus en el mismo periodo, esta caída puede tener una persistencia de sobre ocho trimestres y resultar en contracciones permanentes de hasta 2%, lo que implica un costo indirecto significativo relacionado a la enfermedad de no haberse implementado o de levantarse las medidas de aislamiento actuales y bajo escenarios de contagio conservadores. A su vez, se resalta la importancia de continuar mitigando el impacto económico negativo del aislamiento mediante medidas de política fiscal expansivas.

This study aims to examine the effect of 3 auditor intelligence, that is intellectual intelligence, emotional intelligence and spiritual intelligence on the accuracy of giving opinions with experience as a moderating at KAP in South Jakarta. The population in this study was the auditor at a public accounting firm in the South Jakarta area. The sampling method uses convenience sampling, based on the ease of access and availability of respondents. The number of samples 38 respondents from 5 KAP. The data analysis method uses simple linear regression and MRA.

The results of the research before being moderated showed that intellectual intelligence had a significant effect on the accuracy of giving opinions. emotional intelligence does not significantly influence the accuracy of opinion giving, spiritual intelligence significantly influences the accuracy of giving opinion. Then the results of research after moderation showed that intellectual intelligence is moderated by experience does not effect the accuracy of opinion giving, emotional intelligence is moderated by experience does not effect the accuracy of opinion giving, and Spiritual intelligence moderated by experience does not effect the accuracy of opinion giving. This shows that experience cannot strengthen the effect of auditor intelligence on the accuracy of opinion giving. This shows that the experience of an auditor is not necessarily able to strengthen the auditor's decision making, especially in terms of the accuracy of opinion giving

The phenomenon associated with the occurrence of fraud in BPR is that it is closely related to the role of BPR internal control, which does not systematically oversee leadership in monitoring, evaluating and reporting all processes and stages of activities. As in the case of an error at BPR Nusamba, one of the employees who collects savings and credit installments, must be deposited with client money but extortion occurs on BPR Nusamba cash, with the amount of money reaching Rp 115,429,909. The sample of this study was respondents who received authority in the use of funds in 27 BPR Batam City units. The results of the study stated that partially and simultaneously the application of accounting information systems and internal controls significantly influence accounting fraud.

Sugar beet is an extensive crop of great agronomic value with significant productive and economic returns and Ukraine’s sugar beet accounts for about 5.1% of the overall world production. Sugar beets and the by-products resulting from its manufacturing transformation are a significant renewable energy resource. A new high-quality performance prototype of a sugar beet top harvester, front mounted on a tractor, was built by the authors in Ukraine. The aim of this study is to evaluate the main performance parameters related to the operation of this new machine. Field tests were carried out linking the prototype to a wheel tractor, whilst suitable sensors measured the significant kinematic and dynamic parameters, allowing experimental data collection to assess the machine’s performance parameters. The entire technological process of harvesting and transporting the beet tops to the beet top storage unit required power ranging from 6.42 to 17.65 kW. At the topmost tested forward speed, the required tractor traction force was less than 1.9 kN with the power required by the shaft that drives the screw conveyor ranging from 3.1 to 4.6 kW. This value was the lowest for a speed of the tractor–beet top harvesting machine aggregate ranging from 0.9 to 1.2 m · s − 1 .

Although renewable technologies are progressing fast, there are still challenges such as the reliability and availability of renewable energy sources and their cost issues due to capital intensity that hinder their broad adoption. This research aims at developing a configuration-sizing approach to enhance the cost efficiency and sourcing reliability of renewable energies integrated in microgrids. To achieve this goal, various technologies were considered, such as solar PV, wind turbines, converters, and batteries for system configuration with minimization of net present cost (NPC) as the objective. Grid connection scenarios with up to 100% renewable contribution were analyzed. The results show that the integration of renewable technologies with some grid backup could reduce the levelized cost of energy (LCOE) to about half of the price of the electricity that the university purchases from the grid. Also, different kinds of solar tracker systems were studied. The outcome shows that by using a vertical axis solar tracker, the LCOE of the system could be reduced by more than 50 percent. This research can help the decision-maker to opt for the best scenarios for generating reliable and cost-efficient electricity.

Published: July 2020

Recently, the development in combining point forecasts of electricity prices obtained with different length of calibration windows have provided an extremely efficient and simple tool for improving predictive accuracy. However, the proposed methods are strongly dependent on expert knowledge and may not be directly transferred from one to another model or market. Hence, we consider a novel extension and propose to use principal component analysis (PCA) to automate the procedure of averaging over a rich pool of predictions. We apply PCA to a panel of over 650 point forecasts obtained for different calibration windows length. The robustness of the approach is evaluated with three different forecasting tasks, i.e., forecasting day-ahead prices, forecasting intraday ID3 prices one day in advance, and finally very short term forecasting of ID3 prices (i.e., six hours before delivery). The empirical results are compared using the Mean Absolute Error measure and Giacomini and White test for conditional predictive ability (CPA). The results indicate that PCA averaging not only yields significantly more accurate forecasts than individual predictions but also outperforms other forecast averaging schemes.

Authors: Solomou Ioulia , Constantinidou Fofi
Published: July 2020

Effective management of the global pandemic caused by Severe Acute Respiratory Syndrome Coronavirus 2 (also known as COVID-19), resulted in the implementation of severe restrictions in movement and enforcement of social distancing measures. This study aimed to understand and characterize the psychosocial effects of the COVID-19 pandemic in the general population and to identify risks and protective factors that predict changes in mental health status. In addition, the study investigated compliance with precautionary measures (PM) to halt the spread of the virus. The online anonymous survey collected information on sociodemographic data, compliance with PM, quality of life (QOL), and mental health via the Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9). A total of 1642 adult participants (71.6% women, 28.4% men) completed the survey in the European island country, Cyprus. A large percentage (48%) reported significant financial concerns and 66.7% significant changes in their QOL. About 41% reported symptoms associated with mild anxiety; 23.1% reported moderate-severe anxiety symptoms. Concerning depression, 48% reported mild and 9.2% moderate-severe depression symptoms. Women, younger age (18–29), student status, unemployment status, prior psychiatric history, and those reporting greater negative impact on their QOL, were at higher risk for increased anxiety and depression symptoms (p < 0.05). The youngest age group and males also reported lower levels of compliance with PM. Higher compliance with PM predicted lower depression scores (p < 0.001) but higher anxiety for measures related to personal hygiene. The results of this study provide important data on the effects of the COVID-19 outbreak on mental health and QOL and identify a variety of personal and social determinants that serve as risks and protective factors. Furthermore, it has implications for policy makers demonstrating the need for effective mental health programs and guidance for the implementation of PM as a public health strategy.

Research in preschool children that investigates the impact of different exercise interventions on physical fitness is limited. This pre–post study was aimed at determining if participation in a nine-month structured multisport program (MSG; n = 38) could enhance physical fitness components compared to a formal exercise program (control group (CG); n = 36) among preschool children. Physical fitness was assessed using standardized tests (the standing long jump, sit and reach, 20 m sprint, sit-ups for 30 s, bent-arm hang, medicine ball throw (MBT), grip strength, 4 × 10 m shuttle run, and 20 m shuttle run tests). The structured multisport program involved fundamental/gross and fine motor skills and ball game-based exercises twice a week. The control group was free of any programmed exercise except for the obligatory program in kindergartens. A mixed ANOVA demonstrated significant group-by-time interaction effects for the 4 × 10 m shuttle run, standing long jump, sit-ups, bent-arm hang, grip strength, and sit and reach tests (p < 0.05). There was no significant group-by-time interaction effect for the 20 m sprint test (p = 0.794) or for the 20 m shuttle run test (p = 0.549). Moreover, the MSG and CG performance in the MBT and 20 m shuttle run tests improved to a similar extent from pre- to post-test. Our results indicate that compared to the formal plan, the structured multisport program led to a sustained improvement in physical fitness in healthy 5-to-6-year old children.

Published: July 2020

European chestnut orchards are multifunctional agroforestry systems with a key role in environmental management. Their biodiversity is at risk of erosion and farmers do not have enough tools to protect and valorize traditional ecotypes. In particular, cost effective and reliable molecular markers for cultivar identification are lacking. The aim of this research was to develop a new molecular tool for varietal identification in European chestnuts. A set of cultivars was preliminarily characterized to evaluate the range of genetic diversity using random amplified polymorphic DNA (RAPD) markers. The genetic distances indicated a sufficiently wide variability range among tested genotypes and confirmed they were suitable for our goal. A single nucleotide polymorphism (SNP) mining within 64 expressed sequence tags (EST), covering all the linkage groups, was performed by high-resolution melting (HRM) and validated by target resequencing. Fifty-six SNPs were retrieved by monitoring the variability present on the whole set of considered cultivars in loci uniformly distributed on the genome. A subset of 37 SNPs was finally transformed into kompetitive allele-specific PCR (KASP) markers that were successfully evaluated for varietal discrimination. Three assays (C1083, G0115 and A5096) were identified as necessary and sufficient for distinguishing among the tested cultivars. The developed tools can be effectively exploited by stakeholders for improving the management of the European chestnut genetic resources.

Unraveling the role of cytochrome P450 monooxygenases (CYPs/P450s), heme-thiolate proteins present in living and non-living entities, in secondary metabolite synthesis is gaining momentum. In this direction, in this study, we analyzed the genomes of 203 Streptomyces species for P450s and unraveled their association with secondary metabolism. Our analyses revealed the presence of 5460 P450s, grouped into 253 families and 698 subfamilies. The CYP107 family was found to be conserved and highly populated in Streptomyces and Bacillus species, indicating its key role in the synthesis of secondary metabolites. Streptomyces species had a higher number of P450s than Bacillus and cyanobacterial species. The average number of secondary metabolite biosynthetic gene clusters (BGCs) and the number of P450s located in BGCs were higher in Streptomyces species than in Bacillus, mycobacterial, and cyanobacterial species, corroborating the superior capacity of Streptomyces species for generating diverse secondary metabolites. Functional analysis via data mining confirmed that many Streptomyces P450s are involved in the biosynthesis of secondary metabolites. This study was the first of its kind to conduct a comparative analysis of P450s in such a large number (203) of Streptomyces species, revealing the P450s’ association with secondary metabolite synthesis in Streptomyces species. Future studies should include the selection of Streptomyces species with a higher number of P450s and BGCs and explore the biotechnological value of secondary metabolites they produce.

Published: July 2020

Testicular germ cell tumors (TGCTs) are predominant in young males (15–44 years). Seminomatous and non-seminomatous TGCTs account for about 98% of all TGCTs cases. In this study, we aimed to compare the sperm proteome of patients with seminomatous and non-seminomatous TGCTs to identify possible protein biomarkers that could help distinguish between them in a non-invasive manner. We analyzed semen samples from patients with seminomatous or non-seminomatous TGCTs (n = 15/group) that were cryopreserved before the start of cancer treatment. Quantitative proteomic analysis was conducted on pooled samples (n = 3/group) and a total of 258 differentially expressed proteins (DEPs) were identified. The overexpression of acrosin precursor (ACR) and chaperonin containing TCP1 subunit 6B (CCT6B) as well as the underexpression of S100 calcium-binding protein A9 (S100A9) in the spermatozoa of patients with non-seminomatous TGCTs were validated by western blotting conducted on individual samples (n = 6 for seminomatous group and n = 6 for non-seminomatous group). Our overall results suggest an association between the higher and faster invasiveness of non-seminomatous TGCTs and the altered protein expressions, providing important information for future studies.
Non-Human Primate-Derived Adenoviruses for Future Use as Oncolytic Agents?
Authors: Bots Selas T.F. , Hoeben Rob C.
Published: July 2020

Non-human primate (NHP)-derived adenoviruses have formed a valuable alternative for the use of human adenoviruses in vaccine development and gene therapy strategies by virtue of the low seroprevalence of neutralizing immunity in the human population. The more recent use of several human adenoviruses as oncolytic agents has exhibited excellent safety profiles and firm evidence of clinical efficacy. This proffers the question whether NHP-derived adenoviruses could also be employed for viral oncolysis in human patients. While vaccine vectors are conventionally made as replication-defective vectors, in oncolytic applications replication-competent viruses are used. The data on NHP-derived adenoviral vectors obtained from vaccination studies can only partially support the suitability of NHP-derived adenoviruses for use in oncolytic virus therapy. In addition, the use of NHP-derived adenoviruses in humans might be received warily given the recent zoonotic infections with influenza viruses and coronaviruses. In this review, we discuss the similarities and differences between human- and NHP-derived adenoviruses in view of their use as oncolytic agents. These include their genome organization, receptor use, replication and cell lysis, modulation of the host’s immune responses, as well as their pathogenicity in humans. Together, the data should facilitate a rational and data-supported decision on the suitability of NHP-derived adenoviruses for prospective use in oncolytic virus therapy.

Published: July 2020

Enterobacter sp. LU1, a wild-type bacterium originating from goat rumen, proved to be a potential succinic acid producer in previous studies. Here, the first complete genome of this strain was obtained and analyzed from a biotechnological perspective. A hybrid sequencing approach combining short (Illumina MiSeq) and long (ONT MinION) reads allowed us to obtain a single continuous chromosome 4,636,526 bp in size, with an average 55.6% GC content that lacked plasmids. A total of 4425 genes, including 4283 protein-coding genes, 25 ribosomal RNA (rRNA)-, 84 transfer RNA (tRNA)-, and 5 non-coding RNA (ncRNA)-encoding genes and 49 pseudogenes, were predicted. It has been shown that genes involved in transport and metabolism of carbohydrates and amino acids and the transcription process constitute the major group of genes, according to the Clusters of Orthologous Groups of proteins (COGs) database. The genetic ability of the LU1 strain to metabolize a wide range of industrially relevant carbon sources has been confirmed. The genome exploration indicated that Enterobacter sp. LU1 possesses all genes that encode the enzymes involved in the glycerol metabolism pathway. It has also been shown that succinate can be produced as an end product of fermentation via the reductive branch of the tricarboxylic acid cycle (TCA) and the glyoxylate pathway. The transport system involved in succinate excretion into the growth medium and the genes involved in the response to osmotic and oxidative stress have also been recognized. Furthermore, three intact prophage regions ~70.3 kb, ~20.9 kb, and ~49.8 kb in length, 45 genomic islands (GIs), and two clustered regularly interspaced short palindromic repeats (CRISPR) were recognized in the genome. Sequencing and genome analysis of Enterobacter sp. LU1 confirms many earlier results based on physiological experiments and provides insight into their genetic background. All of these findings illustrate that the LU1 strain has great potential to be an efficient platform for bio-based succinate production.
