The effects of two digestates split up in liquid and solid fractions were investigated on tomato production. The objectives were (1) to verify if the two digestates different in composition differently affected the growth and the quality of tomato; (2) to assess the effectiveness of the two digestate fractions (liquid and solid) on tomato growth and quality characteristics of the harvested tomato fruit. In short, our results evidenced different effects between the two digestates and also between solid and liquid fractions, suggesting that the type of solid fraction (Uliva or Fattoria) rather than the concentration, or their interaction mainly influenced plant growth parameters. Conversely, the effectiveness of liquid fractions were mostly due to the concentrations rather than to the type of digestate. Results also evidenced positive effects of both digestates on the nutritional values of tomatoes, largely explained by the increase in various health-promoting compounds, including vitamin C, flavonoids, and phenolic compounds. The contemporary increase in these different bio-compounds with a wide range of physiological properties and multi target actions confers to digestate treated tomato a nutraceutical benefit. The use of both fractions of both digestates as fertilizer may represent an effective strategy to obtain, even if in some cases at the expense of growth, high-quality fruit in a sustainable way from an economic and environmental point of view.

Consumption of tomato fruits, like those of many other plant species that are part of the human diet, is considered to be associated with several positive effects on health. Indeed, tomato fruits are an important source of bioactive compounds with known beneficial effects including vitamins, antioxidants, and anticancer substances. In particular, antioxidant metabolites are a group of vitamins, carotenoids, phenolic compounds, and phenolic acid that can provide effective protection by neutralizing free radicals, which are unstable molecules linked to the development of a number of degenerative diseases and conditions. In this review, we will summarize the recent progress on tomatoes nutritional importance and mechanisms of action of different phytochemicals against inflammation processes and prevention of chronic noncommunicable diseases (e.g., obesity, diabetes, coronary heart disease, and hypertension). In addition, we will summarize the significant progress recently made to improve the nutritional quality of tomato fruits through metabolic engineering and/or breeding.

Single Stress

In light of foreseen global climatic changes, we can expect crops to be subjected to several stresses that may occur at the same time, but information concerning the effect of long-term exposure to a combination of stresses on fruit yield and quality is scarce. This work looks at the effect of a long-term combination of salinity and high temperature stresses on tomato yield and fruit quality. Salinity decreased yield but had positive effects on fruit quality, increasing TSS, acidity, glucose, fructose and flavonols. High temperatures increased the vitamin C content but significantly decreased the concentration of some phenolic compounds (hydroxycinnamic acids and flavanones) and some carotenoids (phytoene, phytofluene and violaxanthin). An idiosyncrasy was observed in the effect of a combination of stresses on the content of homovanillic acid O-hexoside, lycopene and lutein, being different than the effect of salinity or high temperature when applied separately. The effect of a combination of stresses may differ from the effects of a single stress, underlining the importance of studying how stress interactions may affect the yield and quality of crops. The results show the viability of exploiting abiotic stresses and their combination to obtain tomatoes with increased levels of health-promoting compounds.

The construction and selection of a suitable bijective function, that is, substitution, is now becoming an important applied task, particularly for building block encryption systems. Many articles have suggested using different approaches to determining the quality of substitution, but most of them are highly computationally complex. The solution of this problem will significantly expand the range of methods for constructing and analyzing scheme in information protection systems. The purpose of research is to find easily measurable characteristics of substitutions, allowing to evaluate their quality, and also measures of the proximity of a particular substitutions to a random one, or its distance from it. For this purpose, several characteristics were proposed in this work: difference and polynomial, and their mathematical expectation was found, as well as variance for the difference characteristic. This allows us to make a conclusion about its quality by comparing the result of calculating the characteristic for a particular substitution with the calculated mathematical expectation. From a computational point of view, the thesises of the article are of exceptional interest due to the simplicity of the algorithm for quantifying the quality of bijective function substitutions. By its nature, the operation of calculating the difference characteristic carries out a simple summation of integer terms in a fixed and small range. Such an operation, both in the modern and in the prospective element base, is embedded in the logic of a wide range of functional elements, especially when implementing computational actions in the optical range, or on other carriers related to the field of nanotechnology.

As bison is characteristically dark in colour, this study was conducted to determine if high-voltage electrical stimulation (HVES) could improve the colour and other quality characteristics in bison, similar to positive effects of HVES previously observed in beef. Forty bison bull carcasses were split and HVES (400 V peak, 5 ms pulses at 15 pulses s−1 for 30 s) was applied to the right sides and subsequently evaluated for grade characteristics, metabolic activity, and quality characteristics. The bison carcasses used in this study had a wide range of lean and fat, with minimal marbling. In the present study, HVES had no effect on bison quality traits, sensory attributes, retail display characteristics, nor the glycolytic metabolites (P > 0.05) except lactate. Inherent differences in muscle fibre type or physical carcass differences may have influenced the response to the electrical parameters used in the present study and merits further investigation.

Improving the nutritional quality of plants has emerged from the fact that macro- and micro- nutrients are limited in various agricultural areas. The aim of our study was the biofortification of broccoli sprouts with selenium nanoparticles (NSePs) and evaluation of growth parameters, assimilator pigments content, total phenols, glucosinolates content along with antioxidant capacity, in order to boost value added output, such as improved nutrition and food functionality. NSePs were prepared by reduction of NaHSeO3 using glucose as reducing agent, and characterized from structural and morphological point of view. The growth of broccoli seedlings was dependent on NSePs concentration. The treatment with 10 and 50 ppm NSePs caused a slight increase in total biomass, by contrast with 100 ppm treatment. Chlorophyll content, total carotenoid and total phenols content was not affected by the treatment of broccoli sprouts with different concentrations of NSePs. Instead, the content of individual glucosinolates varied between the samples, depending on the levels of NSePs. The highest antioxidant capacity was obtained for 100 ppm NSePs concentration. The effective uptake of NSePs was further demonstrated by FTIR spectroscopy and Hyperspectral Microscopy. NSePs did not induce any toxicity on broccoli sprouts. Moreover, broccoli supply with NSePs may target higher nutritional impact and health benefits.   ********* In press - Online First.

SummaryMedical guidelines aim to ensure that care processes take place in an evidence-based and structured manner. They are especially relevant in outpatient primary care due to the wide range of symptoms and clinical pictures. In German-speaking countries, there is a lack of current findings documenting general practitioners’ opinions and experiences regarding guidelines, their expectations and their views on what improvements could be made to increase the use of this type of evidence-based instrument in the primary care setting. Between April and August 2020, a total of 3098 general practitioners were surveyed in the states of Baden–Württemberg, Hesse and Rhineland–Palatinate via an online questionnaire. Alongside the descriptive evaluation, t‑testing was used to determine significant differences between two independent sampling groups. A factor analysis was also used to cluster the expectations of those surveyed regarding the fulfilment of requirements relating to guidelines. A total of 52% of those surveyed have a positive view of guidelines. Overall, guidelines are associated with an increased evidence-based approach (69%), standardisation of diagnosis and treatment (62%) and a reduction in overprovision or underprovision of care (57%). In all, 62% of the physicians who implemented guidelines observed positive effects on the quality of care provided, and 67% reported that the implementation of guidelines improved the quality of their diagnostic or therapeutic skills. However, implementation is often seen as being complicated (43%) and restricting the physician’s ability to act independently (63%). Survey participants suggested that guidelines could be optimised by giving greater consideration to nondrug alternatives (46%), focusing on issues related to quality of life (42%) and offering a comparative assessment of various treatment options (39%). In order to further promote the attractiveness of guidelines for primary care the design of guidelines should be oriented more towards their application; they should be well-presented to make them easier to implement. The scope of action available to the physician should be stressed. The guidelines should provide recommendations on opportunities for the delegation of tasks within practice teams.

Relevance. Public health is one of the key factors in the development of the economy and at the same time an objective indicator of quality of life. Currently, the number of women over 50 years old is progressively increasing, and their growing social inclusion will determine the desire for active and healthy longevity. In this regard, the public health policy in the country should follow the path of increasingly large-scale financing of projects of a healthy lifestyle, not concentrating expenses only on medical care. Aim. Analysis of literature on the feasibility of using vitamin D as a factor that improves the quality of life of women in the perimenopausal period and in menopause. Materials and methods. To write this review, we searched for domestic and foreign publications in Russian and international search engines (PubMed, eLIBRARY, etc.) over the past 20 years. The review included articles from peer-reviewed literature. Results. The review outlines a wide range of biological properties of vitamin D involved in the regulation of many important physiological functions. The negative effect of vitamin D deficiency is presented not only on the development of cancer, cardiovascular diseases, but also on the increase in the severity of menopausal syndrome. It has been established that the use of colecalciferol (vitamin D3) in combination with menopausal hormone therapy contributes to the normalization of carbohydrate, lipid and calcium phosphorus metabolism, improves the neuropsychic state of patients, which makes it possible to actively use colecalciferol in routine clinical practice in menopausal syndrome. Conclusions. Numerous positive effects of colecalciferol (vitamin D3) allow the use of the drug as a means to increase social adaptation, and, consequently, improve the quality of life.

Plant biostimulants are under investigation as innovative products to improve plant production and fruit quality, without resulting in environmental and food contaminations. Here, the effects of the application of Expando, a biostimulant based on seaweed and yeast extracts, on plant productivity, fruit ripening times, and fruit quality of Solanum lycopersicum var. Micro-Tom were evaluated. After biostimulant treatment, a two-week reduction of ripening times and a concomitant enhancement of the production percentage during the earliest ripening times, in terms of both fruit yield (+110%) and size (+85%), were observed. Concerning fruit quality, proximate analysis showed that tomatoes treated with the biostimulant had better nutritional composition compared to untreated samples, since both the quality of unsatured fatty acids (C16:3ω3: +328%; C18:2ω6: −23%) and micronutrients essential for human health (Fe: +14%; Cu: +21%; Zn: +24%) were increased. From a nutraceutical point of view, despite strong changes in bioactive compound profile not being observed, an increase of the antioxidant properties was recorded in fruits harvested by plants treated with the biostimulant (2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS): +38%; 2,2-diphenyl-1-picrylhydrazyl (DPPH): +11%). In conclusion, the biostimulant application was able to reduce the ripening times and fruit size, while slightly increasing nutritional and nutraceutical values, leading to more marketable tomato fruits.

PurposeThe purpose of this paper is to analyse the quality of banking services provided in support of small- and medium-sized enterprises' (SMEs) internationalization from the customers' perspective.Design/methodology/approachCustomer satisfaction of 50 Italian SMEs with the banking services provided for international activities has been evaluated by adopting the Kano model's continuous and discrete analyses.FindingsResults show which banking services provided for business internationalization are necessary to satisfy customers' expectations, which services customers like having and dislike not having and which services are unexpected by customers creating a high increase in satisfaction when provided.Research limitations/implicationsThis work shows the value of the Kano model in evaluating the non-linear relationship between customer satisfaction and quality of banking services for the international activities of companies. The main limitation of this work is the limited geographical context of the investigation.Practical implicationsThis research suggests banks to transform their role in the relationship with SMEs from mere financiers to active partners committed to their growth abroad by offering a wide range of services not just financial, but also counselling and care professional, thus achieving mutual benefits.Originality/valuePrevious works on banking services and business internationalization are focussed on the transaction costs, information asymmetries and the impact of online banking. This work advances available knowledge by analysing the customer's point of view, evaluating the satisfaction of SMEs which, although more dependent on banks for their expansion abroad than large listed companies, are mostly ignored by literature.

The development and use of age and growth studies on New Zealand marine fishes are reviewed. A summary of studies on 62 species is given. In view of the wide range of approaches and variation in the level of validation, the studies are not interpreted in detail, but-where available-age at maturity and maximum recorded age are given. The species for which von Bertalanffy growth parameters are available are listed, but, because of variation in the quality of results, not the values. The direction being taken in ageing studies in New Zealand is discussed: age validation, routine ageing of some major commercial species (leading to modelling), basic age-growth information on little-studied species, and theoretical studies on fish ageing. A comprehensive bibliography is included.
