The New Urban Agenda (Agenda 2030) adopted at the United Nations Conference related to Sustainable Urban Development (Habitat III) in the year 2016 has the goal of prompting cities to achieve the identified Sustainable Development Goals by the year 2030. In this context, cities can experiment strategies of circular economy for the optimization of resources, waste reduction, reuse, and recycling. The data generated by the components of an Internet of Things (IoT) ecosystem can contribute in two relevant ways to a smart city model: (1) by the generation of a circular economy and (2) by the creation of intelligence to improve the decision-making processes by citizens or city managers. In this context, it is in our interest to understand the most relevant axes of the research related to IoT, particularly those based on the LoRa technology. LoRa has attracted the interest of researchers because it is an open standard and contributes to the development of sustainable smart cities, since they are linked to the concepts of a circular economy. Additionally, the intention of this work is to identify the technological or practical barriers that hamper the development of solutions, find possible future trends that could exist in the context of smart cities and IoT, and understand how they could be exploited by the industry and academy.

Cancer represents a worldwide public health problem, with high incidence and mortality rates in developed and undeveloped countries. Cur-rently, therapeutic alternatives of natural origin are being evaluated with the purpose of establishing more efficient and less invasive treatments. Apoptosis is the type of programmed death cancer cells undergo during treatment with anti-neoplastic drugs. Therefore, the aim of this research was to evaluate in vitro the pro-apoptotic and cytotoxic capacity of valerian extracts on a breast cancer cell line (MCF-7). In this study, MCF7 cells were cultured and treated with different concentrations of the extracts of the root, leaves and stems of Valeriana rígida and Valeriana decussata. Cell viability was assessed by the MTT assay. Quantitative reverse transcription PCR assays were used for the determi-nation of gene expression of anti- and proapoptotic proteins (Bax, Bcl-2, p53). Different concentrations of the extracts (10–8 to 10–1 mg/mL) decreased cell viability (proliferation) in a concentration-dependent manner. These extracts induced gene expression of Bax and Bcl-2 proteins but not of p53. The expres-sion of Bax was higher than that of Bcl-2, causing an elevated Bax/Bcl-2 ratio (proapoptotic condition). In conclusion, it was determined that Valeriana de-cussata and Valeriana rígida extracts have a viability (proliferation) reducing effect on the MCF-7 breast cancer cell line, probably mediated by altering the ratio of Bax and Bcl-2 proteins linked to apoptosis.
