Dendrimer And Dendrimer Gel-Derived Drug Delivery Systems: Breaking Bottlenecks Of Topical Administration Of Glaucoma Medications, Juan Wang, Boxuan Li, Uday B. Kompella, Hu Yang

Chemical and Biochemical Engineering Faculty Research & Creative Works

Due to high structural flexibility, multidrug carrying capability, and tunable size, dendrimers have been used as suitable carriers for ophthalmic drug delivery. Drug molecules can be either encapsulated or chemically coupled to dendrimers. the nanoscopic size, spheroidal shape, and cationic surface of Poly amidoamine (PAMAM) dendrimers promote their interaction with the cornea and result in prolonged precorneal retention. Dendrimers could be further cross-linked to produce three-dimensional hydrogel networks or dendrimer hydrogels (DH). the properties of the DH can be readily adjusted to maintain both fluidity and adhesiveness, making them suitable for developing topical ocular drug formulations. Micro-/nano- sized DHs, that …

Finite Element Procedure To Simulate Sandwich Structure With An Auxetic Core Under Impact Loading Using Abaqus/Explicit, Valdo Pratama, Annisa Jusuf, Arief Yudhanto, Bambang Kismono Hadi

Mechanical and Aerospace Engineering Faculty Research & Creative Works

A sandwich structure with an auxetic core is promising in improving the performance of a sandwich structure by implying an auxetic core as its core to combine the advantages of the two structures, e.g., sandwich structure's superior ability in flexural and shear resistance, auxetic structure in localizing damage, and densification phenomena. This paper discusses a finite element modeling procedure to simulate a sandwich structure with a heterogeneous re-entrant auxetic core. The material of the face is a unidirectional carbon fiber reinforced polymer (UD CFRP) and the core is polylactic acid (PLA). The model is subjected to a low-velocity impact loading …

Knockout Of Ace-N Facilitates Improved Cardiac Function After Myocardial Infarction, Hamid Suhail, Hongmei Peng, Jiang Xu, Hani N. Sabbah, Khalid Matrougui, Tang-Dong Liao, Pablo A. Ortiz, Kenneth E. Bernstein, Nour-Eddine Rhaleb

Hypertension and Vascular Research Articles

Angiotensin-converting enzyme (ACE) hydrolyzes N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) into inactive fragments through its N-terminal site (ACE-N). We previously showed that Ac-SDKP mediates ACE inhibitors' cardiac effects. Whether increased bioavailability of endogenous Ac-SDKP caused by knocking out ACE-N also improves cardiac function in myocardial infarction (MI)-induced heart failure (HF) is unknown. Wild-type (WT) and ACE-N knockout (ACE-NKO) mice were subjected to MI by ligating the left anterior descending artery and treated with vehicle or Ac-SDKP (1.6 mg/kg/day, s.c.) for 5 weeks, after which echocardiography was performed and left ventricles (LV) were harvested for histology and molecular biology studies. ACE-NKO mice showed increased plasma …

Is Internet Voting Trustworthy? The Science And The Policy Battles

The University of New Hampshire Law Review

According to clear scientific consensus, no known technology can make internet voting secure. In some applications—such as e-pollbooks (voter sign-in), voter registration, and absentee ballot request—it is appropriate to use the internet, as the inherent insecurity can be mitigated by other means. But the insecurity of paperless transmission of a voted ballot through the internet cannot be mitigated.

The law recognizes this in several ways. Courts have enjoined the use of certain paperless or internet-connected voting systems. Federal law requires states to allow voters to use the internet to request absentee ballots but carefully stops short of internet ballot return …

The Policy Environment Of Self-Care: A Case Study Of The Philippines, Leonardo Jaminola Iii, Jana Marie Negre, Veincent Christian F. Pepito, Arianna Maever Loreche, Manuel M. Dayrit

Ateneo School of Medicine and Public Health Publications

Self-care is the ability and empowerment of individuals to maintain health through informed health-care decisions, with or without the support of a health provider. High-income countries have made advances to their conceptualization, research and institutionalization of self-care, given its reported benefits to patients, the health system and economy. A similar undertaking in low- and middle-income countries (LMICs) with already fragile health systems is warranted as highlighted by the coronavirus disease 2019 pandemic. Our article therefore aimed to describe and analyse the policy environment of self-care using the Philippines as a case study, which may have relevance to other similar countries …

Collaboration And Writing Development In L2 Spanish: A Microanalytic Perspective, Brian Olovson

Dimensions

This case study focuses on how two learners position themselves as partners in a collaborative writing activity in a Spanish Writing course. I utilize a micro-discourse analytic approach (Eskildsen & Markee, 2018; van Compernolle, 2015, 2018) to highlight the situated nature of collaboration and the dynamicity of the collaborative writing process as it unfolds turn-by-turn during their interactions. This type of analysis permits researchers to explore how learners orient to their partners and to the language they are producing, and what learners do with their talk (Markee, 2000), so that researchers can observe their competence-in-action (Pekarek Doehler, 2013). The discursive …

Developing Model Federal Legislation To Advance Safe And Responsible Ocean Carbon Dioxide Removal Research In The United States, Romany M. Webb, Korey Silverman-Roati

Sabin Center for Climate Change Law

This model federal legislation aims to advance safe and responsible ocean carbon dioxide removal (CDR) research in U.S. waters. Controlled field trials and other in-ocean research is critical to improve scientific and societal understanding of CDR techniques that could help the U.S. reach its climate goals. However, existing legal frameworks were not designed to regulate ocean CDR and, in some cases, unnecessarily or inappropriately restrict needed research. The purpose of this proposed model legislation is to establish clear and efficient permitting regime for in-ocean CDR research. At the same time, the model legislation builds in consultation, monitoring, and other safeguards …
