Determination of potentially mycotoxigenic fungi in coffee (Coffea arabica L.) from Nayarit
Paloma Patricia Casas-Junco,Juan Arturo Ragazzo-Sánchez,Felipe de Jesus Ascencio-Valle,Montserrat Calderón-Santoyo 한국식품과학회 2018 Food Science and Biotechnology Vol.27 No.3
A total of fourteen roasted coffee samples were collected from different local markets in Nayarit, Mexico. Twenty-two fungi isolates were related to the genera Aspergillus (54.54%) and Penicillium (4.5%). The strains R16 (0.33 μg/kg), 6N (1.16 μg/kg) and 11 (0.36 μg/kg) tested positive for OTA (ochratoxin A) production in PDA, the other fungi samples were not toxigenic. According to the sequence analysis of their ITS1-5.8S-ITS2 rDNA region, fungi OTA producers correspond to A. niger, A. versicolor and Byssochlamys spectabilis. These three strains were able to produce OTA when inoculated in roasted coffee in concentrations ranging from 75 to 90 μg/ kg, after 21 days. Different production stages of roasted coffee (crop management, postharvest practices and storage) along with environmental conditions do not ensure mycotoxigenic fungi free products. This is the first report of OTA natural occurrence in roasted coffee from Nayarit.
Gender Equality and Sustainable Development
Paloma Duran y Lalaguna,Ekaterina Dorodnykh 연세대학교 빈곤문제국제개발연구원 2018 Journal of Poverty Alleviation and International D Vol.9 No.1
Gender-related constraints have high costs to society in terms of untapped potential in achieving poverty eradication, health, education, food security, environmental and energy sustainability, and economic growth. There is strong evidence that closing gender gap accelerates progress towards the achievement of Sustainable Development Goals. While there has been some progress towards better gender equality, there is much more to be done in abolishing gender discrimination. This paper showcases various approaches and interventions to promote gender equality, implemented by the UN development mechanism, SDG Fund and its precursor the MDG Fund. The case studies represent various geographical regions (Bangladesh, the occupied Palestinian territory, Vietnam, Ethiopia, Bolivia and Nicaragua) and confirm the importance of joint efforts to promote and protect the rights of women and girls with the aim to support sustainable development. Finally, various approaches and interventions to promote gender equality (mainly through capacity development, legislative and policy frameworks, advocacy and communication, increased awareness on gender equality and women empowerment, economic and political empowerment and access to health) confirm that gender equality is a multi-dimensional issue which needs to be addressed by a range of solutions and actors. Sustainable development can never be attained without the empowerment of women and girls. Urgent actions are needed to empower women and girls, ensuring that they have equal opportunities to benefit from development and removing the barriers that prevent them from being full participants in all spheres of society.

Cinema is the “the Seventh Art” and cinema is valued socially for its enormous capacity to evoke feelings, awaken consciences, and represent the most sublime of the human spirit and soul. Cinema stories are elaborate constructs of narrative, technical and aesthetic elements whose result is a final product with the antagonistic ability to entertain in an alienating way or even change the thinking of a society regarding a certain issue. Through movies, generations receive aesthetic educations: the way of behaving is learned, the way of speaking and dressing is imitated, an atmosphere of the past is reproduced, trying to represent the Zeitgeist and evoke the great themes that oscillate in each society. Without a doubt, the arrival of cinema into lives in the 20th century marks the ways generations socialize, while forever changing the transmission of ideas, values, and aesthetics.
Legacy transmission through fashion films: Visual and narrative brand heritage integration
Paloma Díaz Soloaga,Dominguez Gemma Muñoz,Zhou Jing 한국마케팅과학회 2023 Journal of Global Fashion Marketing Vol.14 No.4
On this research, we analyze how fashion houses transmit the spirit of the brands, convey the values that constitute their identity and show their heritage through fashion films. High end luxury brands with a long heritage such as Dior and Chanel, use audiovisual narratives fashion films, a form of visual and artistic communication, where the content establishes an emotional relationship between brand and customers and recreates the origins of the brand. Authors primarily selected, classified, and analyzed all fashion films that Chanel and Dior had published on YouTube, and then study a series of represen- tative samples selected from all those contents created by fashion brands. Based on the number of views, likes and comments of each video, it is possible to see the interaction between the brand and the audience and the engagement among the different fashion films. It also delves into the key of the brand to unearth the inheritance and tradition of its origin, trying to record the history of “Maison” to reach a wider audience and convey a series of values to new digital con- sumers. The combination of heritage and vitality through digital activities is oriented to deliver values that have a significant impact on the audience.

Influence of the cathode catalyst layer thickness on the behaviour of an air breathing PEM fuel cell
Ferreira-Aparicio, Paloma,Chaparro, Antonio M. Techno-Press 2014 Advances in energy research Vol.2 No.2
Fuel cells of proton exchange membrane type (PEMFC) working with hydrogen in the anode and ambient air in the cathode ('air breathing') have been prepared and characterized. The cells have been studied with variable thickness of the cathode catalyst layer ($L_{CL}$), maintaining constant the platinum and ionomer loads. Polarization curves and electrochemical active area measurements have been carried out. The polarization curves are analyzed in terms of a model for a flooded passive air breathing cathode. The analysis shows that $L_{CL}$ affects to electrochemical kinetics and mass transport processes inside the electrode, as reflected by two parameters of the polarization curves: the Tafel slope and the internal resistance. The observed decrease in Tafel slope with decreasing $L_{CL}$ shows improvements in the oxygen reduction kinetics which we attribute to changes in the catalyst layer structure. A decrease in the internal resistance with $L_{CL}$ is attributed to lower protonic resistance of thinner catalyst layers, although the observed decrease is lower than expected probably because the electronic conduction starts to be hindered by more hydrophilic character and thicker ionomer film.

Background/Aims: Surgery is the mainstay of treatment for cholecystitis. However, gallbladder stenting (GBS) has shown promise in debilitated or high-risk patients. Endoscopic transpapillary GBS and endoscopic ultrasound-guided GBS (EUS-GBS) have been proposed as safe and effective modalities for gallbladder drainage. Methods: Data from patients with cholecystitis were prospectively collected from August 2004 to May 2013 from two United States academic university hospitals and analyzed retrospectively. The following treatment algorithm was adopted. Endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy and cystic duct stenting was initially attempted. If deemed feasible by the endoscopist, EUS-GBS was then pursued. Results: During the study period, 139 patients underwent endoscopic gallbladder drainage. Among these, drainage was performed in 94 and 45 cases for benign and malignant indications, respectively. Successful endoscopic gallbladder drainage was defined as decompression of the gallbladder without incidence of cholecystitis, and was achieved with ERCP and cystic duct stenting in 117 of 128 cases (91%). Successful endoscopic gallbladder drainage was also achieved with EUS-guided gallbladder drainage using transmural stent placement in 11 of 11 cases (100%). Complications occurred in 11 cases (8%). Conclusions: Endoscopic gallbladder drainage techniques are safe and efficacious methods for gallbladder decompression in non-surgical patients with comorbidities.
