Our study provided the LC50 values of these benzoic acids for human cells in vitro and suggested their mild toxicity that should be considered in the industrial and agricultural applications to be within safe limits. © 2020 The Author(s).We use the closure and the theta omega closure operators to introduce θ ω -continuous, ω-θ-continuous, weakly θ ω -continuous and faintly θ ω -continuous as new four classes of functions. We obtain several properties, relationships, examples and counter-examples related to them. © 2020 The Authors.Antibiotics released in the environment have attracted great attention. The environmental emission control of antibiotics should be based on the degree of their negative impacts on the environment and ecology. Here, we conducted a series of soil slurry microcosm experiments to investigate the interactions between antibiotics and the soil bacterial community. In the soil slurry, distinctive behaviors were observed for different antibiotics. Beta-lactams (ampicillin and ceftriaxone) experienced fast biodegradation. Kanamycin was adsorbed on soil particles soon after its addition. Nalidixic acid was stable throughout the experimental period (164 h). The main inactivation mechanism of tetracycline was deduced to be hydrolysis. Bacterial communities in slurries with or without antibiotic-treatment were profiled via high-throughput Illumina sequencing of the 16S rRNA gene. Unstable (ceftriaxone) and adsorbed (kanamycin) antibiotics show minor or negligible influences on the soil bacterial community. Stable antibiotics (nalidixic acid and tetracycline) have significantly affected the structure of the bacterial community. Most of enriched bacterial genera by various antibiotics belong to the same phylum, Proteobacteria. Inhibited bacterial phyla by nalidixic acid are Firmicutes and Bacteroidetes, while those inhibited by tetracycline are Firmicutes, Bacteroidetes and Cyanobacteria. According to the PICRUSt prediction of metagenome, influence of antibiotics on overall metabolic function of the bacterial community is rather limited. This study has provided valuable information, from a phylogenetic viewpoint, about the influence of high concentration of antibiotics on soil bacterial community. © 2020 The Author(s).Malignant cells reprogram metabolic pathways to meet the demands of growth and proliferation. These altered manners of metabolism are now identified as hallmarks of cancer. Studies have revealed tumor cells alter specific pathways such as glycolysis, fatty acid synthesis and amino acid synthesis to support their proliferation. In this review, we provide a theoretical framework to understand metabolic reprogramming and the mechanisms accompanying distorted metabolism to tumor progression. How these alterations will be assisting in cancer diagnostics and advances in standard techniques in marker identification and imagining are also discussed. © 2020 The Authors. Published by Elsevier Ltd.Spreading of manure on agricultural soils is a main source of ammonia emissions and/or nitrate leaching. It has been addressed by the European Union with the Directives 2001/81/EC and 91/676/EEC to protect the environment and the human health. The disposal of manure has therefore become an economic and environmental challenge for farmers. Thus, the conversion of manure via anaerobic digestion in a biogas plant could be a sustainable solution, having the byproducts (solid and liquid digestates) the potential to be used as fertilizers for crops. This work aimed at characterizing and assessing the effect of digestates obtained from a local biogas plant (Biogas Wipptal, Gmbh), either in the form of liquid fraction or as a solid pellet on (i) the fertility of the soils during an incubation experiment; (ii) the plant growth and nutritional status of different species (maize and cucumber). Moreover, an extensive characterization of the pellet was performed via X-ray microanalytical techniques. The data obtained showed that both digestates exhibit a fertilizing potential for crops, depending on the plant species and the fertilizer dose the liquid fraction increases the shoot fresh weight at low dose in cucumber, conversely, the solid pellet increases the shoot fresh weight at high dose in maize. The liquid digestate may have the advantage to release nutrients (i.e. nitrogen) more rapidly to plants, but its storage represents the main constraint (i.e. ammonia volatilization). Indeed, pelleting the digestates could improve the storability of the fertilizer besides enhancing plant nutrient availability (i.e. phosphate and potassium), plant biomass and soil biochemical quality (i.e. microbial biomass and activity). The physical structure and chemical composition of pellet digestates allow nutrients to be easily mobilized over time, representing a possible source of mineral nutrients also in long-term applications. © 2020 Published by Elsevier Ltd.The purpose of this study is to examine the effect of accrual earnings management and business strategy to bankruptcy risk. Multiple Least Square (MLS) regression and robust regression of M-Estimator regression are performed on financial data of 1,068 non-financial firms listed on the Indonesia Stock Exchange (IDX). The result indicates that there is no relationship between earnings management and bankruptcy risk, while firms that implement either one of two generic business strategies of cost leadership or differentiation, significantly mitigate the risk of bankruptcy. The effect of earnings management to bankruptcy risk is essential for external stakeholders, such as investors and creditors, to assess bankruptcy risk, financial capability, and credit worthiness of a firm, while business strategy effect on bankruptcy risk benefits internal stakeholders, such as managers, in formulating strategies to deal with going concern issues. © 2020 The Authors. AZD1152-HQPA in vivo Published by Elsevier Ltd.Urinary dipsticks are often used for the diagnosis of kidney, liver, metabolic, and urogenital diseases in cattle clinical practice for the simplicity of use and ease of access. The aims of the present study were to evaluate the agreement between urinary dipsticks and pH-meter for the urine pH in dairy cattle, and also to compare the urine pH before and after centrifugation from each method. The agreement between urine dipstick and pH-meter methods before and after centrifuge were calculated by Passing-Bablok regression analysis demonstrated constant differences (intercept) at 0.60 and -1.01 and positive proportional differences (slope) at 0.94 and 1.13; respectively. Total bias estimated by Bland-Altman plot analysis before (0.20) and after (0.14) centrifuge were lower than the acceptable bias in urine samples. The regression analysis of this study emphasized that the urinary dipstick can be used to determine the cattle urine. © 2020 The Authors.
