Objectives: Retinal ischemia-reperfusion injury (RIRI) is the common pathological basis of many ophthalmic diseases in the later stages, and inflammation is the primary damage mechanism of RIRI. Our study aimed to assess whether electroacupuncture (EA) has a protective effect against RIRI and to elucidate its related mechanisms.

Methods: A high-intraocular pressure (HIOP) model was used to simulate RIRI in Wistar rats. EA was applied to the EA1 group [Jingming (BL1) + Shuigou (GV26)] and the EA2 group [Jingming (BL1) + Hegu (LI4)] respectively for 30 min starting immediately after the onset of reperfusion and repeated (30 min/time) at 12 h …

Intellectual Property, Independent Creation, And The Lockean Commons, Mala Chatterjee

Faculty Scholarship

Copyrights and patents are differently structured intellectual property rights in different kinds of entities. Nonetheless, they are widely regarded by U.S. scholars as having the same theoretical underpinnings. Though scholars have sought to connect philosophical theories of property to intellectual property, with a particular interest in the labor theory of John Locke, these explorations have not sufficiently probed copyrights’ and patents’ doctrinal differences or their philosophical implications for the theories explored. This Article argues that a defining difference between copyrights and patents has normative significance for the framework of Lockean property theory: namely, that copyright law treats independent creation as …

Accommodating Parents, Joshua Gupta-Kagan

Faculty Scholarship

The child protection legal system is supposed to work towards the reunification of parents and children in foster care through individualized services to help parents raise their children safely. But that legal system has long been criticized for frequent and severe invasions into the family integrity rights of parents with disabilities and their children, treating parental disabilities as grounds for permanent separation instead of individual characteristics to be accommodated. Several years ago, it seemed that the law was turning. In 2015, the U.S. Departments of Health and Human Services and Justice issued joint guidance stating that the Americans with Disabilities …

Effects Of Socioeconomic Status, Demographic Characteristics, And Education On Sarcopenic Obesity, Moruf Oladele Olaleye

Walden Dissertations and Doctoral Studies

The general problem is that although the body of research about obesity is robust, there is a lack of research addressing the problem of sarcopenic obesity. Specifically, there is a lack of research examining the statistical significance of the relationship between the independent variables of socioeconomic status, demographic characteristics, and education and the dependent variable of sarcopenic obesity. This research may advance practice and policy by lending support for developing interventions to address factors that have a statistically significant relationship with sarcopenic obesity. The purpose of this quantitative causal-comparative study was to identify independent variables among socioeconomic, demographic, and education …

Numerous studies have revealed the critical role of premature senescence induced by various cancer treatment modalities in the pathogenesis of aging-related diseases. Senescence-associated secretory phenotype (SASP) can be induced by telomere dysfunction. Telomeric DNA damage response induced by some cancer treatments can persist for months, possibly accounting for long-term sequelae of cancer treatments. Telomeric DNA damage-induced mitochondrial dysfunction and increased reactive oxygen species production are hallmarks of premature senescence. Recently, we reported that the nucleus-mitochondria positive feedback loop formed by p90 ribosomal S6 kinase (p90RSK) and phosphorylation of S496 on ERK5 (a unique member of the mitogen-activated protein kinase family …
