The virus spike (S) protein finds its binding site, ACE2, widely distributed in all cells and tissues that potentially proffer CoViD-19 pathology. S consists of two subunits, S1 and S2, which are cleaved by the widely expressed transmembrane protease serine 2 (TMPRSS2) before the virus fuses to the plasma membrane and infects the cell. Current trends show that variant alleles resulting from single nucleotide polymorphisms (SNPs) of ACE2, and genetic variants of TMPRSS2, with putative distinct affinities for S clip, may determine a complex multi-factorial spectrum of SARS-CoV2 virulence across patients, and predict CoViD-19 susceptibility.We correct some numerical results of [Chaos Solitons Fractals 135 (2020), 109846], by providing the correct numbers and plots. The conclusions of the paper remain, however, the same. In particular, the numerical simulations show the suitability of the proposed COVID-19 model for the outbreak that occurred in Wuhan, China. This time all our computer codes are provided, in order to make all computations reproducible. The authors would like to apologize for any inconvenience caused.We propose a Susceptible-Infected-Recovered (SIR) modified model for Coronavirus disease - 2019 (COVID-19) spread to estimate the efficacy of lockdown measures introduced during the pandemic. As input data, we used COVID-19 epidemiological information collected in fifteen European countries either in private surveys or using official statistics. Thirteen countries implemented lockdown measures, two countries (Sweden, Iceland) not.  https://www.selleckchem.com/products/cp2-so4.html  As output parameters, we studied herd immunity level and time of formation. Comparison of these parameters was used as an indicator of effectiveness / ineffectiveness of lockdown measures. In the absence of a medical vaccine, herd immunity may be regarded as a factor of population adaptation to severe acute respiratory syndrome-related coronavirus-2, the viral pathogen causing COVID-19 disease (SARS-CoV-2), and hence COVID-19 spreading stop. We demonstrated that there is no significant difference between lockdown and no-lockdown modes of COVID-19 containment, in terms of both herd immunity level and the time of achieving its maximum. The rationale for personal and business lockdowns may be found in the avoidance of healthcare system overburdening. However, lockdowns do not prevent any virus with droplet transmission (including SARS-CoV-2) from spreading. Therefore, in case of a future viral pathogen emergence, lockdown measures efficiency should not be overestimated, as it was done almost universally in the world during COVID-19 pandemic.
  The increasingly complex treatment options for oncological diseases with multimodal treatment strategies transcend the boundaries of asingle discipline and require multidisciplinary cooperation in order to ensure guideline-based and patient-oriented care.
 
  The implementation of an effective tumour board is required in the goals of the National Cancer Plan of the Federal Ministry of Health and the certification guidelines of the German Cancer Society.
 
  In Germany, specialist competence in the field of oncological nursing has so far rarely been integrated.
 
  The Konferenz Onkologischer Kranken- und Kinderkrankenpflege (KOK), aworking group of SectionB in the German Cancer Society, is working intensively on strengthening the role of oncological nursing so that oncological nurses and advanced practice nurses specialising in oncology, as an integral part of the multidisciplinary team, can contribute valuable nursing aspects, taking into account the individual patient perspective, and thus improve the quality of oncological care.

This happened also, and mainly, within the educational institutions, where students and teachers had to rearrange their teaching/learning dynamics because of the forced education at a distance. In this paper, we present an exploratory qualitative study with secondary school students aimed to investigate how they were experiencing their learning during lockdown and how, in particular, learning of science contributed to rearranging their daily lifetime rituals. In order to design and carry out our investigation, we borrowed constructs coming from a research field rather unusual for science education the field of sociology of time. The main result concerns the discovery of the potential of the dichotomy between alienation from time and time re-appropriation. The former is a construct elaborated by the sociologist Hartmut Rosa to describe the society of acceleration in the "era of future shock". The latter represents an elaboration of the construct of appropriation that the authors had operationally defined, starting from Bakhtin's original idea, to describe the nexus between physics learning and identity. Thanks to the elaboration of the notion of time re-appropriation as feature of the "era of present shock", the study unveils how school science, instead of preparing the young to navigate our fast-changing and complex society, tends to create "bubbles of rituals" that detach learning from societal concern.
  Food systems are associated with severe and persistent problems worldwide. Governance approaches aiming to foster sustainable transformation of food systems face several challenges due to the complex nature of food systems.
 
  In this commentary we argue that addressing these governance challenges requires the development and adoption of novel research and innovation (R&I) approaches that will provide evidence to inform food system transformation and will serve as catalysts for change. We first elaborate on the complexity of food systems (transformation) and stress the need to move beyond traditional linear R&I approaches to be able to respond to persistent problems that affect food systems. Though integrated transdisciplinary approaches are promising, current R&I systems do not sufficiently support such endeavors. As such, we argue, we need strategies that trigger a double transformation - of food systems and of their R&I systems.
 
  Seizing the opportunities to transform R&I systems has implications for how research is done - pointing to the need for competence development among researchers, policy makers and society in general - and requires specific governance interventions that stimulate a systemic approach.
