The aim of the paper is to present green infrastructure planning within the concept of climate-smart cities. In this context the use of Geographic Information Systems (GIS), as part of green infrastructure planning, is stressed in the establishment of climate-smart cities. In addition to presenting international examples of good practice, such as using GIS data, maps and tools for support in the USA, or designing a tool for water management and water infrastructure planning in Chicago, the paper provides an insight into the current status of green infrastructure planning in Serbia. The ?Green regulation of Belgrade? project is presented as a representative example. The conclusions emphasise that the main preconditions for achieving climate-smart and green cities include legal and planning frameworks, as well as appropriate strategic and other programs that will further encourage the creation of GIS for green areas and create the conditions for climate-smart green infrastructure planning.

The COVID-19 pandemic generated a number of changes in the functioning of urban areas all over the world and had a visible impact on the use of green infrastructure, including city parks. The study discusses and compares operation and use of two such parks located in Wellington, New Zealand and Warsaw, Poland by adopting “pandemic urban ethnography”, an approach that includes autoethnography, interviews with users, non-participant observation, and analysis of social media content. As indicated by the findings of the study, the importance of less rigidly designed, multifunctional spaces that give their users freedom of “tactical” adjustments, significantly grows during times of lockdown and “social distancing”. During such a crisis, the management and everyday use of urban parks are highly related to urban policies. The article provides insight into how those policies impact the functional values of green infrastructure confronting it with user-generated adaptations and the landscape design itself. The global health emergency showed how access to green areas becomes a crucial determinant on environmental justice while proving the significance of “tactical pandemic urbanism” as both a design and management method.

Purpose – The purpose of this paper is to consider the understanding and presence of sustainability within entrepreneurship education. The extant literature on sustainability within the entrepreneurship discipline remains extremely limited. Previously, sustainability within an entrepreneurship context has related to economic viability as opposed to sustainability in its broadest sense. This study explores, through a survey of entrepreneurship educators, three key research questions, namely, how entrepreneurship educators believe that entrepreneurs can contribute to solving sustainability problems. Second, to what extent education about sustainability is integrated within existing entrepreneurship curricula. Finally, what considerations are being made to include sustainability within future programmes. Design/methodology/approach – This study represented part of a larger university project exploring the associations between the sustainability and entrepreneurship disciplines. This part of the study involved a web-based survey from entrepreneurship academics drawn from Australia, New Zealand, UK, and the USA which provided 54 completed questionnaires. Findings – The study uncovered much good practice led by “champions” within the entrepreneurship discipline. However, embedded sustainability practice was typically limited and it was more typically regarded as an “add-on” to traditional entrepreneurial teaching. Practical implications – The study proposes three ways in which sustainability might be more meaningfully integrated into entrepreneurship programmes. First, the QAA (2012) guidelines for enterprise and entrepreneurship need to be reconsidered to encapsulate the sustainability agenda. Second, for entrepreneurship educators to reconsider their pedagogical approaches to encapsulate systems thinking as more holistic educational perspective. Finally, the authors call for entrepreneurship educators to revise their programmes to embed the core facets of social, environmental, economic, and more recently ethical sustainability. Originality/value – The study offers a novel insight into entrepreneurship educators attitudes to sustainability and their approach to it within their curricula. This study provides an initial benchmark regarding the levels of sustainability provision within entrepreneurship curricula which will be of interest to the entrepreneurship academic community, the sustainability community, and policy makers.

Background: Biopharmaceuticals such as Biologic medicinal products have been in clinical use over the past three decades and have benefited towards the therapy of degenerative and critical metabolic diseases. It is forecasted that market of biologics will be going to increase at a rate of 20% per year, and by 2025, more than ˃ 50% of new drug approvals may be biological products. The increasing utilization of the biologics necessitates for cost control, especially for innovators products that have enjoyed a lengthy period of exclusive use. As the first wave of biopharmaceuticals is expired or set to expire, it has led to various opportunities for the expansion of bio-similars i.e. copied versions of original biologics with same biologic activity. Development of biosimilars is expected to promote market competition, meet worldwide demand, sustain the healthcare systems and maintain the incentives for innovation. Methods: Appraisal of published articles from peer reviewed journals, PubMed literature, latest news and guidelines from European Medicine Agency, US Food Drug Administration (FDA) and India are used to identify data for review. Results: Main insight into the quality requirements concerning biologics, current status of regulation of biosimilars and upcoming challenges lying ahead for the upgrading of marketing authorization of bio-similars has been incorporated. Compiled literature on therapeutic status, regulatory guidelines and the emerging trends and opportunities of biosimilars has been thoroughly stated. Conclusion: Updates on biosimilars will support to investigate the possible impact of bio-similars on healthcare market.

Selective killing of cancer cells while sparing healthy ones is the principle of the perfect cancer treatment and the primary aim of many oncologists, molecular biologists, and medicinal chemists. To achieve this goal, it is crucial to understand the molecular mechanisms that distinguish cancer cells from healthy ones. Accordingly, several clinical candidates that use particular mutations in cell-cycle progressions have been developed to kill cancer cells. As the majority of cancer cells have defects in G1 control, targeting the subsequent intra‑S or G2/M checkpoints has also been extensively pursued. This review focuses on clinical candidates that target the kinases involved in intra‑S and G2/M checkpoints, namely, ATR, CHK1, and WEE1 inhibitors. It provides insight into their current status and future perspectives for anticancer treatment. Overall, even though CHK1 inhibitors are still far from clinical establishment, promising accomplishments with ATR and WEE1 inhibitors in phase II trials present a positive outlook for patient survival.

AbstractBeef and its products are an important source of nutrition in many human societies. Methods of production vary and include the use of hormonal compounds (‘hormones’) to increase growth and lean tissue with reduced fat deposition in cattle. The hormonal compounds are naturally occurring in animals or are synthetically produced xenobiotics and have oestrogenic (oestradiol-17β and its esters; zeranol), androgenic (testosterone and esters; trenbolone acetate) or progestogenic (progesterone; melengestrol acetate) activity. The use of hormones as production aids is permitted in North American countries but is no longer allowed in the European Union (EU), which also prohibits the importation of beef and its products derived from hormone-treated cattle. These actions have resulted in a trade dispute between the two trading blocs. The major concern for EU authorities is the possibility of adverse effects on human consumers of residues of hormones and metabolites. Methods used to assess possible adverse effects are typical of those used by international agencies to assess acceptability of chemicals in human food. These include analysis of quantities present in the context of known biological activity and digestive, absorptive, post-absorptive and excretory processes. Particular considerations include the low quantities of hormonal compounds consumed in meat products and their relationships to endogenous production particularly in prepubertal children, enterohepatic inactivation, cellular receptor- and non-receptor-mediated effects and potential for interference with growth, development and physiological function in consumers. There is particular concern about the role of oestradiol-17β as a carcinogen in certain tissues. Now subject to a ‘permanent’ EU ban, current evidence suggests that certain catechol metabolites may induce free-radical damage of DNA in cell and laboratory animal test systems. Classical oestrogen-receptor mediation is considered to stimulate proliferation in cells maintaining receptivity. Mathematical models describing quantitative relationships between consumption of small amounts of oestrogens in meat in addition to greater concentrations from endogenous production, chemical stoichiometry at cellular level and human pathology have not been developed. Such an approach will be necessary to establish ‘molecular materiality’ of the additional hormone intake as a component of relative risk assessment. The other hormones, although generally less well researched, are similarly subject to a range of tests to determine potentially adverse effects. The resulting limited international consensus relates to the application of the ‘precautionary principle’ and non-acceptance by the European Commission of the recommendations of the Codex Alimentarius Commission, which determined that meat from cattle, hormone-treated according to good practice, was safe for human consumers. The present review considers the hormone issue in the context of current international social methodology and regulation, recent advances in knowledge of biological activity of hormones and current status of science-based evaluation of food safety and risk for human consumers.
