La filosofía del diálogo intercultural en el pensamiento de Raúl Fornet-Betancourt

En este trabajo se analiza la propuesta del filósofo cubano, Raúl Fornet-Betancourt, acerca del diálogo intercultural. Frente a un mundo cada vez más globalizado por el racionalismo económico y la monoculturalidad, el autor considera que la alternativa es la crítica para un “des-filosofar la filosofía” (logocéntrismo), que no ha permitido el reconocimiento de las otras culturas desde un contexto en el que la polifonía de voces (dialogicidad), sean escuchadas por todos sin menoscabo de ninguna.En este trabajo se analiza la propuesta del filósofo cubano, Raúl Fornet-Betancourt, acerca del diálogo intercultural.

Gen-Z ambassadors: students supporting persons with Alzheimer’s disease and their caregivers in the Rio Grande Valley

Background: Youth participation in policy, research, education and community development initiatives is a right embedded in the United Nations Convention on the Rights of the Child (UNCRC, General Assembly, 1989). However, avenues for youth participation in health promotion and care remains limited. Our Ambassadors program prepares high-school students on the Texas-Mexico border to understand and empathize with persons with Alzheimer’s disease (PwAD) and to empower their family and caregivers, consummating the UNCRC in the service of transformative community change actions. Methods: Our long-term objective is youth participation, defined as practices that involve collaboration between students and various community stakeholders in AD. The initial phase of the program is the design of a curriculum for early high school students to develop the knowledge, skills and attitudes required for that participation. We used a cooperative strategy (a high school students-faculty collaborative), guided by empowerment and ecological theories to achieve optimal youth advancement in the context of the UNCRC social, health and cultural rights of children. Results: The GenZ Ambassadors curricular units were identified through an iterative process in which faculty documented their activities with youth and tested sessions ranging from the biological basis and clinical presentations of AD to family impact, principles of caregiving, youth as change agents, building intergenerational partnerships, and self-reflection exercises. Ambassadors selected settings and strategies designed to empower their peers and to transform communities by skill and confidence building. Discussion: The process implemented and content analysis revealed a variety of themes that benefited persons with AD and their caregivers in the Rio Grande Valley. Several strategies will be tested to generate interactive training materials and culturally and age-competent as well as delivery strategies, including peer-to-peer delivery

Feeding spectra and activity of the freshwater crab Trichodactylus kensleyi (Decapoda: Brachyura: Trichodactylidae) at La Plata basin

Background: In inland water systems, it is important to characterize the trophic links in order to identify the ‘trophic species’ and, from the studies of functional diversity, understand the dynamics of matter and energy in these environments. The aim of this study is to analyze the natural diet of Trichodactylus kensleyi of subtropical rainforest streams and corroborate the temporal variation in the trophic activity during day hours. Results: A total of 15 major taxonomic groups were recognized in gut contents. The index of relative importance identified the following main prey items in decreasing order of importance: vegetal remains, oligochaetes, chironomid larvae, and algae. A significant difference was found in the amount of full stomachs during day hours showing a less trophic activity at midday and afternoon. The index of relative importance values evidenced the consumption of different prey according to day moments. Results of the gut content indicate that T. kensleyi is an omnivorous crab like other trichodactylid species. Opportunistic behavior is revealed by the ingestion of organisms abundant in streams such as oligochaetes and chironomid larvae. The consumption of allochthonous plant debris shows the importance of this crab as shredder in subtropical streams. However, the effective assimilation of plant matter is yet unknown in trichodactylid crabs. Conclusions: This research provides knowledge that complements previous studies about trophic relationships of trichodactylid crabs and supported the importance of T. kensleyi in the transference of energy and matter from benthic community and riparian sources to superior trophic levels using both macro- and microfauna.Fil: Williner, Verónica.

Addressing the disparities in dementia risk, early detection and care in Latino populations: Highlights from the Second Latinos and Alzheimer's Symposium

The Alzheimer's Association hosted the second Latinos & Alzheimer's Symposium in May 2021. Due to the COVID-19 pandemic, the meeting was held online over 2 days, with virtual presentations, discussions, mentoring sessions, and posters. The Latino population in the United States is projected to have the steepest increase in Alzheimer's disease (AD) in the next 40 years, compared to other ethnic groups. Latinos have increased risk for AD and other dementias, limited access to quality care, and are severely underrepresented in AD and dementia research and clinical trials. The symposium highlighted developments in AD research with Latino populations, including advances in AD biomarkers, and novel cognitive assessments for Spanish-speaking populations, as well as the need to effectively recruit and retain Latinos in clinical research, and how best to deliver health-care services and to aid caregivers of Latinos living with AD

Clinical and Non-Clinical Aspects of Distal Radioulnar Joint Instability

Untreated distal radioulnar joint (DRUJ) injuries can give rise to long lasting complaints. Although common, diagnosis and treatment of DRUJ injuries remains a challenge. The articulating anatomy of the distal radius and ulna, among others, enables an extensive range of forearm pronosupination movements. Stabilization of this joint is provided by both intrinsic and extrinsic stabilizers and the joint capsule. These structures transmit the load and prevent the DRUJ from luxation during movement. Several clinical tests have been suggested to determine static or dynamic DRUJ stability, but their predictive value is unclear. Radiologic evaluation of DRUJ instability begins with conventional radiographs in anterioposterior and true lateral view. If not conclusive, CT-scan seems to be the best additional modality to evaluate the osseous structures. MRI has proven to be more sensitive and specific for TFCC tears, potentially causing DRUJ instability. DRUJ instability may remain asymptomatic. Symptomatic DRUJ injuries treatment can be conservative or operative. Operative treatment should consist of restoration of osseous and ligamenteous anatomy. If not successful, salvage procedures can be performed to regain stability

Real-Time Nanoparticle–Cell Interactions in Physiological Media by Atomic Force Microscopy

Particle–cell interactions in physiological media are important in determining the fate and transport of nanoparticles and biological responses to them. In this work, these interactions are assessed in real time using a novel atomic force microscopy (AFM) based platform. Industry-relevant CeO2 and Fe2O3 engineered nanoparticles (ENPs) of two primary particle sizes were synthesized by the flame spray pyrolysis (FSP) based Harvard Versatile Engineering Nanomaterials Generation System (Harvard VENGES) and used in this study. The ENPs were attached on AFM tips, and the atomic force between the tip and lung epithelia cells (A549), adhered on a substrate, was measured in biological media, with and without the presence of serum proteins. Two metrics were used to assess the nanoparticle cell: the detachment force required to separate the ENP from the cell and the number of bonds formed between the cell and the ENPs. The results indicate that these atomic level ENP–cell interaction forces strongly depend on the physiological media. The presence of serum proteins reduced both the detachment force and the number of bonds by approximately 50% indicating the important role of the protein corona on the particle cell interactions. Additionally, it was shown that particle to cell interactions were size and material dependent
