Antitumor Effect of Cabozantinib in Bone Metastatic Models of Renal Cell Carcinoma
2021
Background: The presence of bone metastases in renal cell carcinoma (RCC) negatively affects patients’ survival. Data from clinical trials has highlighted a significant benefit of cabozantinib in bone metastatic RCC patients. Here, we evaluated the antitumor effect of cabozantinib in coculture models of renal cell carcinoma (RCC) and osteoblasts (OBs) to investigate whether and how its antiproliferative activity is influenced by OBs. Methods: Bone/RCC models were generated, coculturing green fluorescent protein (GFP)-tagged Caki-1 and 786-O cells with human primary OBs in a “cell–cell contact” system. RCC proliferation and the OB molecular profile were evaluated after the cabozantinib treat…
The circular economy for resilience of the agricultural landscape and promotion of the sustainable agriculture and food systems
2022
The agricultural landscape is a public good to be preserved for long-term socio-economic and environmental effects. The agricultural landscape is preserved by the carrying out of agricultural activities. Through a empirical survey we examined how some young farmers in the countryside adopt conservation and resilience strategies. A common feature of the case studies examined is the adoption of photovoltaic energy production necessary for the performance of business activities. The method applied is that of the opportunity cost. The results of the research show that young farmers after graduation have returned to agriculture as they have an advantage in terms of opportunity costs compared to …

Dynamiczna analiza shift share - ocena zmian struktury produkcji zwierzęcej w Polsce
2017
Dynamiczna metoda przesunięć udziałów uwzględnia zmienność wag w kolejnych okresach. Metoda ta została zaproponowana w 1988 przez Barffa i Knighta. Ideą metody jest przeprowadzenie w sposób rekurencyjny obliczeń dla każdych dwóch kolejnych okresów, aby ostatecznie dokonać agregacji wyników cząstkowych. Dodatkowo metoda ta pozwala na określenie tendencji w zakresie przemian gospodarki regionalnej. Celem artykułu jest przedstawienie analizy składników zmiany i możliwości jej wykorzystania do diagnostyki potencjału produkcyjnego rolnictwa regionu, a w szczególności wskazanie obiektów wyspecjalizowanych oraz charakteru zmian strukturalnych w zakresie badanego zjawiska.
Service provision and social cohesion in rural areas: interaction between commuting, mobility and the residential preferences in Latvia
2012
The main issue addressed in this study is interaction of development policy of agricultural and rural areas with the regional and cohesion policies. This paper is based on an empirical study of everyday commuting models and spatial practices of different social groups of rural people in Latvia. This article analyzes data from a survey “Place, capabilities, migration” conducted in 2011 with a total of 1009 respondents in Latvia. The theoretical basis of research is rooted in the mobility studies and sociological and geographical conceptualization of space and place. The main focus is on analysis of relationship between commuting, mobility and the placeattachment. What are the main reasons of…
Bodźce pozacenowe w kontraktach rolnych. Powiązania umowne między grupami producentów rolnych a ich pierwszymi odbiorcami w Polsce
2018
Celem artykułu jest identyfikacja stosowanych bodźców pozacenowych w umowach rolnych, które mogłyby potencjalnie skłaniać agenta do działania zgodnego z interesem kontraktora. Zastosowanie tego typu zachęt może potencjalnie minimalizować problem pokusy nadużycia ze strony agenta jeszcze w trakcie jej obowiązywania, tj. w trakcie produkcji rolnej. Dla realizacji założonego celu wykorzystano badanie własne z użyciem ankiety. Badanie empiryczne przeprowadzono wśród grup producentów rolnych działających na rynku drobiu, a przedmiotem badań były kontrakty rolne podpisane w 2014 roku. Na podstawie przeprowadzonych badań zidentyfikowano bodźce pozacenowe, które mają pomóc monitorować i łagodzić pr…
Combined effect of low-molecular-weight organic acids and creosote on phosphatase activities in sandy soil
2018
This paper assesses the impact of creosote and low-molecular-weight organic acids (LMWOAs) on the activity of acid phosphomonoesterase, alkaline phosphomonoesterase, phosphotriesterase, and inorganic pyrophosphatase in soil. The experiment was carried out on loamy sand samples with organic carbon content of 8.71 g · kg -1 , with the following variable factors: dosages of creosote: 0, 0.5%, and 2.5%; type of LMWOAs: oxalic acid, tartaric acid, and citric acid in the amount of 50 mmol · kg -1 of soil; days of experiment: 1, 7, 14, 28, 56, 112. Obtained results showed that contamination with creosote caused decrease in the activity of soil phosphatases. The observed effect did not always incre…
Scientific productivity and collaboration in viticulture and enology in Latin American countries
2013
[EN] The aim of this study was to analyze the scientific activity of Latin American researchers in viticulture and oenology through bibliometric analyses of articles included in the Science Citation Index Expanded database for the period of 2006 to 2010. A total of 917 research articles were published in 364 domestic and international journals. We highlight the important growth in the number of research papers published during the period, especially in Brazil, Argentina and Chile, as well as an increasing number of international collaborations, mainly with non-American grape- and-wine producing countries. A social network analysis of collaborations between institutions and countries was als…
Towards a framework for assessment and management of cumulative human impacts on marine food webs
2015
Effective ecosystem-based management requires understanding ecosystem responses to multiple human threats, rather than focusing on single threats. To understand ecosystem responses to anthropogenic threats holistically, it is necessary to know how threats affect different components within ecosystems and ultimately alter ecosystem functioning. We used a case study of a Mediterranean seagrass (Posidonia oceanica) food web and expert knowledge elicitation in an application of the initial steps of a framework for assessment of cumulative human impacts on food webs. We produced a conceptual seagrass food web model, determined the main trophic relationships, identified the main threats to the fo…
