Background: Prior clinical trials established the safety, but not the efficacy of bone marrow-derived mesenchymal stromal cells (MSCs) in the acute respiratory distress syndrome (ARDS).

Methods: We conducted a prospective, double-blind, multi-center randomized phase 2b clinical trial of one dose of intravenous MSCs (10 x 106/kg predicted body weight) versus placebo in 120 ventilated patients with ARDS (PaO2/FiO2 < 250 mmHg). The primary endpoint was change in oxygenation index (OI) over 36 hours from baseline.

Findings: Enrollment began in January 2020. Due to the Coronavirus 2019 (COVID-19) pandemic, the majority of subjects (101/120, 84%) developed ARDS from COVID-19. There were no significant baseline differences in severity of illness between patients treated with MSCs and those who received …

Tailoring Hiv/Aids Communication To The Cultural Contexts Of The Borana Pastoral Community In Ethiopia, Dano Olana, Sabihah Moola

Journal of Social, Behavioral, and Health Sciences

The HIV/AIDS health communication approach in sub-Saharan Africa has often overlooked sociocultural specificities. The current approach follows a generalist notion that does not consider the specific contextual domains accordingly. Similarly, the cultural appropriateness of HIV/AIDS health communication among the Borana pastoral community in Ethiopia is not clear. In this study, we aimed to explore whether HIV/AIDS communication among the Borana pastoral community was tailored to the cultural contexts of the community. A qualitative case study was used to unpack the cultural communication contexts for HIV/AIDS. We collected data using three methods, namely, in-depth interviews, focus group discussions, and document analysis …

Synthesis, Characterization, And An Evaluation Of The Biological Activities Of Some New Transition Metal Complexes With Organic Ligand, Ghadeer Alataby, Areej Kamal Assim Aldabbagh

Baghdad Science Journal

The reaction between triethylorthoformate and p-chlorophenyl resulted in formation of N,N'-bis-(p-chlorophenyl)formamidine ligand. Subsequently, this ligand interacted with the following metal ions (Co⁺², Ni⁺², Cu⁺², Cr⁺³ and Ru⁺³) creating air-stable complexes with formula [M(L)₂(H₂O)_n(Cl)_x](X= 0, 1) with distinct octahedral morphologies. The formation of these compounds was identified using mass spectroscopy (MS), which validated the acquired geometries. Fourier transform infrared (FT-IR) spectroscopy analysis demonstrated how the formamidine group formed and how it coordinated with the metal ions.

Sorenson, Evan Cantor, Maria Ghishan, John R. Prensner, Andrea T. Franson, Kevin Ginn, Carl Koschmann, Viveka Nand Yadav

Manuscripts, Articles, Book Chapters and Other Papers

Pediatric high-grade gliomas (pHGGs), particularly diffuse midline gliomas (DMGs), are among the most lethal brain tumors due to poor survival and resistance to therapies. DMGs possess a distinct genetic profile, primarily driven by hallmark mutations such as H3K27M, ACVR1, and PDGFRA mutations/amplifications and TP53 inactivation, all of which contribute to tumor biology and therapeutic resistance. Developing physiologically relevant preclinical models that replicate both tumor biology and the tumor microenvironment (TME) is critical for advancing effective treatments. This review highlights recent progress in in vitro, ex vivo, and in vivo models, including patient-derived brain organoids, genetically engineered mouse models (GEMMs), and …

Virtual Dignitary Torts, Zahra Takhshid

Sturm College of Law: Faculty Scholarship

The emergence of the metaverse and spatial computing, which has enabled immersive digital interactions, raise complex legal questions. This work examines the feasibility of addressing dignitary torts-such as battery and intentional infliction of emotional distress-committed via avatars. The particular challenge for tort law is the nonphysical nature of selfrepresentations in these virtual spaces. Drawing from the historical evolutions of several dignitary torts, such as the law of battery and emotional harm, this article argues that the key in allowing for the recognition of such harms is appreciating the expansion of the protection of physical body within these torts, to the …

Mechanistic Insights Into The Flash Effect: The Role Of Oxygen And Radiation Chemistry In Ultra-High Dose Rate Radiation Therapy, Jacob Pierce Sunnerberg

Dartmouth College Ph.D Dissertations

The development of new cancer therapies focuses on widening the therapeutic ratio between tumor control and normal tissue toxicity. Over the last decade, ultra-high dose rate (UHDR) radiation therapy, commonly known as FLASH radiotherapy (FLASH-RT), has shown promising potential to reduce normal tissue toxicity while maintaining tumor control. However, the underlying mechanisms of the FLASH effect remain poorly understood. This thesis explores the radiation-chemical basis of FLASH-RT, focusing on the role of oxygen and reactive oxygen species in modulating biological outcomes.

A comprehensive set of in vitro studies demonstrated that UHDR delivery significantly alters radiation chemistry compared to conventional dose …

Data Driven Analysis Of Samara Seed Kinematics And Dynamics, Shashwat Sparsh

Master's Theses

Samara Seeds are a class of fruit most famously belonging to the Acer species and are characterized by their single-bladed geometry and their auto-rotation response during descent. This steady-state auto-rotation response is the subject of aerodynamic analysis which aim to quantify the performance. The period prior to the beginning of steady-state auto-rotation is classified as the transition regime and has not been the subject of intense scrutiny.

This thesis employs a data-driven approach to analyzing the kinematic and dynamic response of these seeds during both the transition and auto-rotation stages of flight to quantify the performance with respect to the …

“To Prepare The Mind For Wonder”: Popular Science And Mass Media In The 1920s, Alexander Olson

Journal of 20th Century Media History

This article examines the creation and development of the Science Service, a 1920s initiative aimed at popularizing science through mass media. Founded by biologist William Ritter and newspaper magnate Edward Scripps, the wire service sought to disseminate accurate scientific information to the American public via newspapers, radio, and other popular media. While Scripps favored a commercially viable, accessible style that used entertainment to hook readers, Ritter envisioned science journalism as a tool for democratic education and intellectual empowerment. These conflicting philosophies created lasting tensions within the organization around how to address challenges such as sensationalism, editorial independence, and public skepticism. …

The Great Lakes Entomologist

While specific invertebrate groups have been studied in prairie restorations, there are few studies that look at terrestrial invertebrate assemblages. We surveyed invertebrates in three phases of plant restoration that were part of a larger restoration project. This cross-sectional study of invertebrate recovery at two, four and five years post-restoration shows there was no overall difference in invertebrate taxa richness and diversity between restoration phases. Overall abundance was greatest in the most recently restored area. Richness, diversity and abundance of six functional groups did not differ. The conclusion is that all phases are still characterized by pioneer invertebrate assemblages, and …
