The Effectiveness Of Dental Pulp Stem Cells-Derived Exosomes For Direct Pulp Capping: In Vitro Study, Dina A. Hammouda, Alaa M. Mansour, Mohammed E. Grawish, Ahmed R. Zaher

Mansoura Journal of Dentistry

Objective: This in vitro investigation's goal was to ascertain how well dental pulp stem cell exosomes (DPSC-exo) modulate endogenous dental pulp stem cells (DPSCs) and direct their navigation toward mineralized tissue regeneration, either alone or in conjunction with mineral trioxide aggregate (MTA). Materials and methods: For this investigation, DPSCs were harvested using rat incisors. To extract exosomes from DPSCs, an ultracentrifugation method was employed. Flow cytometry was used for the characterization of DPSCs-exo, and transmission electron microscopy (TEM) was used to measure their size. DPSCs were incubated in standard culture media and split up into three groups. The first one …

The Impact Of Social Media On Charitable Giving For Nonprofit Organization, Namchul Shin

Journal of International Technology and Information Management

Research has extensively studied nonprofit organizations’ use of social media for communications and interactions with supporters. However, there has been limited research examining the impact of social media on charitable giving. This research attempts to address the gap by empirically examining the relationship between the use of social media and charitable giving for nonprofit organizations. We employ a data set of the Nonprofit Times’ top 100 nonprofits ranked by total revenue for the empirical analysis. As measures for social media traction, i.e., how extensively nonprofits draw supporters on their social media sites, we use Facebook Likes, Twitter Followers, and Instagram …

How Does Digitalisation Transform Business Models In Ropax Ports? A Multi-Site Study Of Port Authorities, Yiran Chen, Anastasia Tsvetkova, Kristel Edelman, Irina Wahlström, Marikka Heikkila, Magnus Hellström

Journal of International Technology and Information Management

This article investigates the relationship between digitalisation and business model changes in RoPax ports. The study is based on six RoPax ports in Northern Europe, examining their digitalisation efforts and the resulting changes in their business models, leading to further digital transformation. The paper offers insights by reviewing relevant literature on digitalisation’s role in business model innovation and its application in ports. The findings reveal that digitalisation supports relevant business model changes concerning port operation integration within logistics chains, communication, documentation flow, and cargo flow optimisation. However, exploring digitalisation’s potential for diversifying value propositions is still limited. Most digitalisation efforts …

An Empirical Study To Understand The Role Of Institution-Based Trust And Its Antecedents In Iot Adoption By Individuals, Anupam Kumar Nath, Amit Kumar Nath

Journal of International Technology and Information Management

ABSTRACT

The Internet of Things (IoT) enables the connection between humans, physical objects, and cyber objects, resulting in monitoring, automation, and decision-making capabilities. This connection can be complex and lead to uncertainty for individuals before adopting IoT technology. To address this, we conducted research on the role of Institution-based trust in the context of IoT adoption. Our model for IoT adoption is based on existing literature and includes the components of Institution-based trust and its antecedents. Through empirical testing, we confirmed that Institution-based trust positively affects IoT adoption at the individual level. Additionally, we found that User confirmation/disconfirmation and familiarity …

Medical Expenditures And The Measurement Of Poverty In The United States, Luke Petach, David Wyant

Faculty Scholarship

Using data from the Medical Expenditure Panel Survey (MEPS) we estimate the fraction of the US population that is health poor. A person is health poor if their income prior to paying health insurance premiums and out-of-pocket healthcare costs is above the poverty line, but their income net-of-premiums and out-of-pocket healthcare costs is below the poverty line. Because resources used to finance health insurance premiums and out-of-pocket costs are (A) lexicographically preferred and (B) cannot be used to maintain an individual’s standard of living, they should be excluded from official poverty estimates. Approximately 1% to 2% of the US population …

A Proposal For The Use Of A Fixed Low-Energy Selective Laser Trabeculoplasty For Open Angle Glaucoma, Zachary Sacks, L. Jay Katz, Gus Gazzard, Sarah H. Van Tassel, Eytan Z. Blumenthal, Fabian S. Lerner, Augusto Azuara-Blanco, Gregory John Roy Spooner, Yoram Solberg, Thomas Samuelson, Michael Belkin

Wills Eye Hospital Papers

Selective laser trabeculoplasty (SLT) has been in routine clinical use for over 20 years with millions of patients successfully treated and a low rate of clinically significant complications. The procedure requires the clinician to manually position the laser beam on the trabecular meshwork using a gonioscopy lens and to titrate the SLT laser energy based on the amount of pigmentation in the angle, as well as the observation of small bubbles produced by the laser effect. We propose that SLT energy titration is unnecessary either to achieve intraocular pressure (IOP) reduction or to minimize potential side effects. Ample evidence to …

Image-Based Multiplex Immune Profiling Of Cancer Tissues: Translational Implications. A Report Of The International Immuno-Oncology Biomarker Working Group On Breast Cancer., Shahin Sayed, Chowdhury Arif Jahangir, David Page, Glenn Broeckx, Claudia Gonzalez, Caoimbhe Burke, Clodagh Murphy, Jorge Reis-Filho, Amy Ly, Paul Harms

Pathology, East Africa

Recent advances in thefield of immuno-oncology have brought transformative changes in the management ofcancer patients. The immune profile of tumours has been found to have key value in predicting disease prognosis andtreatment response in various cancers. Multiplex immunohistochemistry and immunofluorescence have emerged aspotent tools for the simultaneous detection of multiple protein biomarkers in a single tissue section, therebyexpanding opportunities for molecular and immune profiling while preserving tissue samples. By establishing thephenotype of individual tumour cells when distributed within a mixed cell population, the identification of clinicallyrelevant biomarkers with high-throughput multiplex immunophenotyping of tumour samples has great potential toguide appropriate treatment …
