Sources of Community for Older Adults: Findings from the COVID-19 Coping Study
One of the most challenging aspects of the COVID-19 pandemic for individuals has been losing a sense of community and connectedness with others. In this presentation we discuss preliminary findings about the impacts on sources of community for older adult participants in the COVID-19 Coping Study, a national longitudinal study that aims to understand how the pandemic is affecting the mental health and well-being of older adults in America. We have been using a collaborative process to code and qualitatively analyze responses from a randomized subset of 500 participants. We will share overarching themes of sources of community that are important to older adults; how the pandemic has affected their engagement with and interactions in these communities; and feelings expressed by participants regarding what they value, miss, and find challenging about their communities during the pandemic. This study has implications for understanding the most important sources of community for older adults and how to better help support those who are struggling with loss of these sources during a crisis or emergency such as this pandemic
Fragmentation of carbohydrate anomeric alkoxy radicals: a new synthesis of chiral 1-halo-1-iodo alditols
10 pages, 3 tables, 2 schemes.-- PMID: 14673851 [PubMed].-- Supporting information (52-page PDF file) available at: http://www.wiley-vch.de/contents/jc_2111/2003/f5294_s.pdfTreatment of 1,2-fluorohydrins, 1,2-chlorohydrins, 1,2-bromohydrins, and 1,2-iodohydrins of the D-gluco, D-galacto, D-lacto, L-rhamno, D-allo, L-arabino, 3-deoxy-D-gluco, and 3,4-dideoxy-D-gluco families of carbohydrates with the (diacetoxyiodo)benzene/iodine system afforded 1-fluoro-1-iodo, 1-chloro-1-iodo, 1-bromo-1-iodo, and 1,1-diiodo alditols, respectively, in excellent yields. The reaction was achieved by radical fragmentation of the C1bond;C2 bond, triggered by the initially formed anomeric alkoxy radical, and subsequent trapping of the C2-radical by iodine atoms. This methodology is compatible with the stability of the protective groups most frequently used in carbohydrate chemistry. The potential utility of these 1-halo-1-iodo alditols as chiral synthons was evaluated by their transformation into alk-1-enyl iodides and in the Takai E-olefination reaction.This work was supported by the Investigation Programs nos.

Layered zeolitic materials: an approach to designing versatile functional solids
Relevant layered zeolites have been considered in this perspective article from the point of view of the
synthesis methodologies, materials characterization and catalytic implications, considering the unique
physico-chemical characteristics of lamellar materials. The potential of layered zeolitic precursors to
generate novel lamellar accessible zeolites through swelling, intercalation, pillarization, delamination and/
or exfoliation treatments is studied, showing the chemical, functional and structural versatility exhibited by
layered zeolites. Recent approaches based on the assembly of zeolitic nanosheets which act as inorganic
structural units through the use of dual structural directing agents, the selective modification of germanosilicates
and the direct generation of lamellar hybrid organic inorganic aluminosilicates are also considered
to obtain layered solids with well-defined functionalities. The catalytic applications of the layered
zeolites are also highlighted, pointing out the high accessibility and reactivity of active sites present in the
lamellar framework.The authors thank financial support to Spanish Government by Consolider-Ingenio MULTICAT CSD2009-00050, MAT2011-29020-C02-01 and Severo Ochoa Excellence Program SEV-2012-0267.Díaz Morales, UM.; Corma Canós, A.

Understanding Intergenerational Conflict
Understanding Intergenerational Conflict
This presentation will introduce findings of current research being completed here are Western Oregon University. The focus of the research is on patterns of conflict among Latinx that may come from cultural expectations. We will explore if the presence of conflict is perceived differently among those coming from a collectivistic culture and potential conflicts between emerging adults and parents. We discuss with students how these conflicts affect relationships and consequences that may emerge. As well as explore our ethnic cultural norms and experiences with conflict and non-family related issues and challenges. In addition to exploring possible conflicts the Latinx population may experience we will provide psychoeducation and coping skills that can support mental health when facing conflict

Differential effects of serotonin reuptake inhibitors on erectile responses, NO-production, and neuronal NO synthase expression in rat corpus cavernosum tissue
Increased incidence of impotence is associated with some selective serotonin-reuptake-inhibitors (SSRIs), but the pathophysiological mechanism is unknown. Paroxetine and citalopram are extensively used SSRIs, but only paroxetine has been shown to inhibit nitric oxide synthase (NOS) activity. NO is a key mediator of penile erection. Thus, the aim of this study was to determine the effects of paroxetine and citalopram on erectile function and NO production, in a rat model. Application of cavernosal nerve electrical stimulation produced frequency-related intracavernosal pressure (ICP) increases, which were inhibited by the NOS inhibitor, N(G)-nitro-L-arginine (0.3 mg kg(−1)). Acute or chronic (2 weeks) paroxetine-treatment (10 mg kg(−1)) reduced ICP-responses, while citalopram did not. Paroxetine, but not citalopram, significantly reduced nitrite+nitrate plasma levels by 61.4% and inhibited penile neuronal NOS (nNOS) protein expression by 31.2% after chronic treatment. The results show that paroxetine inhibits erectile responses in rats. We propose that this effect is due to reduced NO production and nNOS expression
