Published: November 2020

Abstract
Due to its complex biochemical properties, the bee pollen is considered one of the functional foods. Bee pollen collected from pollen grains from different botanical sources offers almost a full diet such as carbohydrates, proteins, amino acids, vitamins, minerals. In this study, methanol extracts of 13 honeybee pollen samples were evaluated for flavonoids, phenolic compounds, and antioxidant capacity. Caffeic acid, chlorogenic acid, vanillic acid, p-coumaric acid, gallic acid, quercetin, rutin, vanillin, and naringin were identified as main phenolic compounds in pollen extracts by High-Performance Liquid Chromatography (HPLC) analysis. The obtained results are: total phenolic content - 379.8 to 915.6 mg GAE/100 g, total flavonoid content - 207.1 to 550 mg QE/100 g, and antioxidant activity - 808.2 to 3311 mg GAE/100 g in bee pollen extracts.

Abstract
The treatment of intestinal inflammation pathologies (also known as Inflammatory Bowel Diseases, IBD) has included a large variety of strategies, from pharmaceutical to traditional medicine and dietary therapies. In the last years, numerous efforts were undertaken to demonstrate the health promoting activities of probiotics in intestinal inflammation and more other pathologic conditions. The aim of our study was to evaluate the effects of a probiotic mixture of Lactobacillus sp. on the inflammatory mediators and signalling pathways as well as nuclear receptors in colonic Caco-2 cells. Human adenocarcinoma Caco-2 cells were challenged in vitro with lipopolysaccharide (LPS) for 4 hours for the induction of inflammation. The LPS-treated cells were cultured for additional 24 hours in the presence of Lactobacillus (Lb) mixture (3 x108 CFU/mL total Lb). Genomic and proteomic array approaches were used to analyse the profile expression of 18 key genes and their proteins involved in intestinal inflammatory response (chemokines, adhesion molecules, growth factors and matrix metalloproteinases inhibitors) as well as signalling markers (Akt, GSK) and nuclear receptors (NF-kB/RELA, Nrf2, AhR). Our study demonstrated that the probiotic Lactobacillus mixture could decrease LPS-induced inflammatory mediator expressions (chemokines, growth factors and matrix metalloproteinases inhibitor) at gene and protein level. This down-regulation exerted by Lb. mix in LPS-treated Caco-2 cells seemed to be regulated through inhibition of both the PI3K/AKT and NF-κB signalling pathways. Additionally, AhR activation induced by LPS was reduced by probiotic mixture under the level of LPS-treated cells. These beneficial effects of Lactobacillus mixture support their use as inflammatory modulators in intestinal disorders.

Published: November 2020

Abstract
For each simple symplectic triple system over the real numbers, the standard enveloping Lie algebra and the algebra of inner derivations of the triple provide a reductive pair related to a semi-Riemannian homogeneous manifold. It is proved that this is an Einstein manifold.
Simultaneous Adsorption of Phenol Derivatives from Water Onto Spherical Activated Carbon
Authors: Kamiński Władysław , Kuśmierek Krzysztof , Świątkowski Andrzej , Tomczak Elwira 
Published: November 2020

Abstract
The paper examines single- and multicomponent adsorption onto granular activated carbon. The quantities adsorbed in the study were determined using HPLC with UV detection. The experimental data were analysed using the Langmuir, the Freundlich and the Sips adsorption isotherms. With a single component being adsorbed, high coefficients of determination and low mean square errors indicated that the Sips isotherm fitted the adsorption equilibrium well. Further experiments were carried out using aqueous solutions containing two or three adsorbed components in different proportions. For these solutions, the literature methods of predicting multicomponent equilibrium using single-component data did not yield positive results. Assuming that in the investigated range of concentrations no competitive adsorption occurred, the authors propose a method for calculating the equilibrium concentrations in the liquid phase using the equations obtained for individual components. The results achieved correspond very well to the experimental data.

Published: November 2020

Abstract
Estimating the interception of radiation is the first and crucial step for the prediction of production for intercropping systems. Determining the relative importance of radiation interception models to the specific outputs could assist in developing suitable model structures, which fit to the theory of light interception and promote model improvements. Assuming an intercropping system with a taller and a shorter crop, a variance-based global sensitivity analysis (EFAST) was applied to three radiation interception models (M1, M2 and M3). The sensitivity indices including main (Si) and total effects (STi) of the fraction of intercepted radiation by the taller (ftaller), the shorter (fshorter) and both intercrops together (fall) were quantified with different perturbations of the geometric arrangement of the crops (10-60 %). We found both ftaller and fshorter in M1 are most sensitive to the leaf area index of the taller crop (LAItaller). In M2, based on the main effects, the leaf area index of the shorter crop (LAIshorter) replaces LAItaller and becomes the most sensitive parameter for fshorter when the perturbations of widths of taller and shorter crops (Wtaller and Wshorter) become 40 % and larger. Furthermore, in M3, ftaller is most sensitive to LAItaller while fshorter is most sensitive to LAIshorter before the perturbations of geometry parameters becoming larger than 50 %. Meanwhile, LAItaller, LAIshorter, and Ktaller are the three most sensitive parameters for fall in all three models. From the results we conclude that M3 is the most plausible radiation interception model among the three models.
The materials to determine the eastern range border of acidophilous oak forestCalamagrostio arundinaceae-Quercetum petraeaein Poland – two new stands of the association in the southern part of Mazovian Voivodeship

AbstractAcidophilous oak forestsCalamagrostio arundinaceae-Quercetum petraeae(hartm. 1934 scam. et Pass. 1959) are mostly known from the western part of Poland, while its eastern border has not been determined accurately. in order to address this issue, we performed a phytosociological analysis of two newly identified stands of acidophilous oak forest located in the southern part of the Mazovian Voivodeship near Kiedrzyn (vicinity of Nowe Miasto nad Pilicą) and Mikówka (vicinity of Białobrzegi). For comparison, we also examined the distribution of known patches in the region (Łódź and Mazovian Voivodeships) against this association’s background of the eastern range border.Within the identified sites, a total of 10 phytosociological relevés were taken and soil samples were collected from a depth of 10 cm. the content of organic matter, soil ph and sieving analysis were performed in the laboratory. the phytosociological material was ordered and numerically classified which gave two groups of relevés: typical for this association (seven relevés) and a degenerated form (three relevés), which has an increased share of pine in the stand. All our relevés were similar to acidophilous oak forests from the Wielkopolska region and thus different from oak-pine forests of eastern Poland. habitat conditions of the patches and the bonitation of oak were analogous to patches of this association from other parts of Poland. Furthermore, the sites we studied are located between known locations from the Bolimowska and Kozienicka Forests and are therefore connecting these two previously known areas of occurrence. this indicates that the range of theCalamagrostio-Quercetumassociation is at least a few dozen kilometers wider in this part of the country than the assumed range.

Can Multinational Corporations be responsible for human rights violation of its outsourcee company? Response of national or international law?
Authors: Suppa Alessandro , Bureš Pavel 
Published: November 2020

Summary
Nowadays, an important role in the world is played by Multinational Corporations (MNCs). They hire, produce, and influence the international economy, but also, they exploit, pollute. Their business activities might have a worldwide effect on human lives. The question of the responsibility of MNCs has drawn the attention of many scholars, mainly from the study field labelled “Business and Human Rights”. The present paper does not examine the topic under the same approach. The authors aim at presenting the issue in a broader perspective, exploring the concept of due diligence both in international and corporate law. In this paper, authors strategically use the uniformity of national legislations as a possible and alternative solution to the issue. They are aware of three fundamental factors: 1) the definition of MNCs needs to be as clear as possible, so to avoid any degree of uncertainty; 2) the outsourcing phenomenon interacts with that definition; 3) in case of no possibility to include outsourcing in the definition of MNC, the original question arises in a significant way.
Joint Tendering in the European Economic Area
Authors: Petr Michal 
Published: November 2020

Summary
The EU regulation of public procurement strives to create a set of rules that would enable the contracting authority to choose the best bid. In order to do so, it also tries to widen the circle of potential bidders by enabling their horizontal (consortia) as well as vertical (subcontracting) cooperation. Such cooperation may enable the participation of undertakings that would not be otherwise in position to bid on their own, thus increasing the number of bidders and promoting competition among them. At the same time, such arrangements may be contrary to competition law which prohibits coordination of competitors. Joint tendering is ubiquitous within the European Economic Area, and yet the case-law on its compliance with competition law is strikingly divergent. This article provides an overview of the current state of play and some suggestions for future practice.

Published: November 2020

Abstract

Background and aims. Aortic sclerosis associates an increased risk of cardiovascular morbidity and mortality. Recent studies suggest that aortic sclerosis is able to produce ventricular remodeling through inflammatory, non-hemodynamic mechanisms. Our study aims to evaluate the correlation between ventricular remodeling and aortic sclerosis severity.

Method. 68 patients with aortic sclerosis without other signifficant associated valvulopathies were examined clinically, biologically and echocardiographic. In 20 patients, we quantiffied the severity of aortic valve calciffication using the backscatter ecographic technique, in parasternal long and short axis view. Backscatter values obtained at the valvular level were calibrated to the blood and pericardium backscatter values.

Results. In the 68 patients group, transvalvular aortic velocity correlates with left ventricular mass (p =0.031), which in turn incline to augment with increasing calciffication severity assessed by backscatter. Calciffication severity assessed by backscatter corellates with transvalvular aortic velocity in parasternal long axis view (p =0.039 for blood calibrated backscatter, p =0.029 for pericardium calibrated backscatter), and tends to augment with increasing transvalvular aortic velocity in parasternal short axis view. Patients with normal ventricular geometry incline to have lower aortic transvalvular velocities and a lower degree of calciffication (evaluated by backscatter) compared to patients with ventricular remodeling.

Conclusions. Aortic sclerosis is not benign, and may lead, in time, to left ventricular remodeling. With the progression of valvular calciffications in aortic sclerosis patients, the prevalence of ventricular remodeling tends to increase.

Abstract

Introduction: The incidence of cardiac arrhythmia is approximately 1% in the neonatal period and 1–3% in late pregnancy. Atrial flutter (AF), a rhythm disorder based on the mechanism of reentry, represents approximately 32% of all neonatal cardiac arrhythmias. In the majority of cases, the flutter is converted to sinus rhythm using antiarrhythmic drugs, transesophageal overdrive pacing, or synchronized electrical cardioversion.

Case presentation: We present a case of a born on term, female infant who was noted to be tachycardic on the fetal monitor. Clinical examination revealed tachypnea and tachycardia with dysrhythmia, at a heart rate of 250 bpm. Electrocardiography showed AF with 2–3 : 1 atrioventricular conduction (atrial and ventricular rates were 350 bpm and 250–275 bpm, respectively). Echocardiography revealed no relevant structural disease. Therapy with amiodarone and prophylactic anticoagulant was initiated. As no control of ventricular rate was obtained and a succession of three ventricular extrasystoles was noted on the surface ECG, propranolol therapy was initiated, without success. Therefore, synchronized electrical cardioversion was applied, with conversion to sinus rhythm at a heart rate of 136 bpm. The neonate was discharged in good condition.

Conclusions: AF is one of the most common high ventricular rate arrhythmias during fetal age. Uncontrolled AF may precipitate heart failure, and prompt restoration to sinus rhythm may require electrical cardioversion in cases refractory to anti-arrhythmic drugs, in order to prevent possible complications.
Transparency dilemma in interpersonal relationships
Authors: Rehman Sharaf 
Published: November 2020

AbstractHumans as social animals move from being strangers to becoming intimate by taking risks of engaging in self-disclosure—from sharing insignificant bits of information to details about their beliefs, opinions, lifestyles, prejudices, and values. Romantic and intimate relationships come about when players peel away their outer layers and allow others to get closer to their core. However, as couples become more familiar, they experience certain tensions known as relational dialectics. These are autonomy versus connection, novelty versus predictability, and openness versus transparency (openness). This paper presents the findings of a survey of the perceptions about these tensions among the Hispanic-America college students (N=108). The subjects rank-order these tensions in terms of their importance, and the level of difficulty in dealing with the tensions.
Does abuse depend on gender? Men as a victim of women’s violence
Authors: Płonka Joanna 
Published: November 2020

Abstract
The aim of this article is an attempt to reflect on what violence is and what effects it can cause. The conventional wisdom has been that women are victims and men are perpetrators of violence and abuse. Social schemes describe women as fragile and vulnerable. However, women can be equally aggressive, dominating and use violence. Each year acts of violence against men increase and it is very important to be aware of this phenomenon. Usually men hide the fact of being abused out of fear of public stigma, felling bashful, being laughed or losing respect of their family. This paper aims to show how important this problem is and explore new ideas and possible solutions for victims of violence, as well as to improve preventive measures for abused men.
African women in search of global identity: An exploration of feminism and Afropolitanism in Chimamanda Adichie’s works
Authors: Eke Gloria Ori , Njoku Anthony 
Published: November 2020

Abstract
Many variants of feminism have been branded over time and that has given feminism a multiple identity. One of the new revelations of feminism in recent times is “Afropolitan Feminism”, a branch of African feminism conceived in this research to deal with the story of African women in the homeland and the Diaspora trying to assume the status of world citizens (Metropolites) to de-emphasize their origins. What is the nature of Afropolitan Feminism? What is the link between Feminism and Afropolitanism? To what extent do Adichie’s characters show the attributes of Afropolitans? This paper illuminates the concepts of feminism and Afropolitanism and the latter’s traits in Adichie’s characters in Americanah and The Thing Around Your Neck. It deals with Diaspora issues and the way African women in literary fictions try to stem the effects of global maladies like African patriarchy, Western racism and sexism. The paper further discusses social awareness and feminist tendencies displayed by the characters. It ends by noting that feminism which assumes the dimension of Afropolitanism in Adichie’s works is a becoming trend rather than a fixed norm.
Cessation of Renin-Angiotensin System Antagonists During the SARS-CoV-2 Pandemic – Do We Have the Evidence?

Published: November 2020

Abstract
The aim of this review is to provide a short update on whether treatment with angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) has beneficial or harmful effects in patients infected with SARS-CoV-2. Epidemiological studies have shown that SARS-CoV-2 infects all age groups, presenting a higher incidence in elderly patients with various comorbidities such as hypertension, diabetes mellitus, and cardiovascular diseases. A large proportion of these patients are treated with ACEIs and ARBs. Since it has been demonstrated that SARS-CoV-2 uses angiotensin converting enzyme type 2 (ACE2) as an entry point into host cells, it is important to know whether ACEIs and ARBs could modify the expression of this enzyme, and thus promote the viral infection. Animal studies and a few studies in humans have shown that renin angiotensin system (RAS) inhibitors increase tissue expression of ACE2, but with potentially beneficial effects. In this context, it is imperative to provide appropriate guidance for clinicians and patients. The major cardiology associations across the world have released statements in which they recommend healthcare providers and patients to continue their treatments for hyper-tension and heart failure as prescribed.

Published: November 2020

Abstract
The novel coronavirus disease first appeared in Wuhan (China) is an infectious disease spreading throughout the world, causing life-threatening conditions in vulnerable or even healthy individuals. The great impact of this virus on healthcare urges physicians to investigate all aspects of the disease in order to overcome its complications. A particularly investigated aspect of the SARS-CoV-2 infection is represented by the coagulation disorders among infected and critically ill patients. Several studies observed modified blood coagulation parameters such as D-dimers, fibrinogen, and coagulation times. Moreover, the severe thrombotic complications, mainly pulmonary embolism, could be responsible for the high mortality and poorer outcomes of COVID-19 infected patients. The aim of this article is to present the current knowledge related to thrombosis predisposition in patients infected with the new coronavirus.

Abstract
We monitored seasonal dynamics of stem water status of four coniferous species (Abies alba, Larix decidua, Picea abies and Pinus sylvestris) planted at the Borová hora Arboretum (300 m a.s.l., Zvolen valley, Central Slovakia) beyond their ecological and production optima, in the region with warmer and drier climate compared to the sites of their origin. Species-specific stem water deficit and maximum daily shrinkage were extracted from diurnal band dendrometer records of stem circumference recorded by digital band dendrometers DRL26 installed on five trees per species, and correlations with environmental variables were analysed. The seasonal stem circumference increment of all tree species was higher in 2017 than in the drier and hotter year of 2018. The greatest seasonal stem circumference increment in the observed periods of 2017 and 2018 was observed for A. alba and P. sylvestris, respectively. The highest and lowest values of daily and seasonal stem water deficit were observed for L. decidua and A. alba, respectively. The analysis of trees' short-term response to extreme climate events seems to be the promising and suitable method for detecting tree species tolerance towards drought.
