Lyophilized L-PRF enhances the bioactivity and rheological properties of 3D-printed and bioprinted scaffolds containing Dental pulp stem cells

Lina María Anaya-Sampayo · Dabeiba Adriana Garcia-Robayo · Nelly S. Roa · Luis Maria Rodriguez-Lorenzo · y 1 más

Bone tissue engineering requires bioinks that combine suitable rheological properties, printability, and biological activity. Leukocyte and platelet-rich fibrin (L-PRF) is a platelet concentrate providing a sustained release of bioactive molecules involved in angiogenesis and osteogenesis.This study aimed to develop an...

Connectedness of fibers beyond semitoric systems I: the non-degenerate case

Sepe, Daniele · Tolman, Susan

Abstract In this paper, we study the connectedness of the fibers of integrable systems that extend complexity one $T$-spaces with proper moment maps, assuming that every tall singular point is non-degenerate. Our main result states that if there are no tall singular points with a hyperbolic block and connected $T$-stab...

From a network to a networking: The evolution of the Latin American Giant Observatory

C. Sarmiento-Cano · H. Asorey · M. Audelo · A.C. Fauth · y 10 más

The Latin American Giant Observatory (LAGO) is a collaborative initiative that deploys a network of low-cost, autonomous Water Cherenkov Detectors across Latin America and Spain. Initially focused on detecting gamma-ray bursts at high-altitude sites, LAGO has evolved into a multidisciplinary forum for astroparticle phy...

Leaving no one behind – Building inclusive circular economies in the Global South

Calderón Márquez, Ana Julieth; id_orcid 0000-0002-7674-0975

Despite growing interest in circular economy (CE) strategies, Global North research and policy frameworks are often applied to the Global South without adaptation. This limits understanding of how to design inclusive CE transitions that reflect the socioeconomic realities of countries in the Global South. This study ad...

In vivo performance of 5-fluorouracil encapsulated on bacterial nanocellulose in an azoxymethane-dextran sulphate sodium induced colorectal cancer: Drug release profiles, histological and biomarkers analysis

Elizabeth, Correa · Estefanía, Martínez · Marlon, Osorio · Vanesa, Bedoya-Betancur · y 3 más

Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide, largely due to its chronic progression and frequent diagnosis at advanced stages. Although surgical resection remains the gold standard for CRC treatment, adjuvant chemotherapy with 5-fluorouracil (5FU) is commonly required; however, its...

Impact of bilateral oophorectomy on survival among patients undergoing radical hysterectomy for cervical adenocarcinoma: a National Cancer Database analysis

Gabriel Levin · Lucy Gilbert · Rene Pareja · Shuk on Annie Leung · y 3 más

The role of bilateral salpingo-oophorectomy at the time of radical hysterectomy for cervical adenocarcinoma remains controversial. We aim to study the impact of bilateral salpingo-oophorectomy on overall survival of women undergoing radical hysterectomy for treatment of cervical cancer, specifically, with adenocarcinom...

Providing a Gender Perspective on Sustainability Competences and Pedagogical Approaches: Experiences of Students From 17 International Case Studies

Gabriela Ortiz‐Martínez · Maria Barreiro‐Gen · Jordi Segalàs · Alberto Mendoza · y 24 más

ABSTRACT During the last three decades, higher education institutions (HEIs) have integrated sustainability into their curricula. Recent research has focused on sustainability competences and pedagogical approaches, and how the latter foster the development of the former. Previous studies have examined the connections...

From categories to producers: Dual regulatory and Anthropocene-based classification of macrolitter on an uninhabited Caribbean island

Nelson, Rangel-Buitrago · Alex, Paternina-Ramos · Lucio, Brabo · Francisco Jailton Silva, Filho · y 8 más

Marine macrolitter accumulation on islands provides a sensitive indicator of regional transport processes and production-consumption dynamics. In this study, coastal macrolitter assemblages were assessed on Isla Arena, a small uninhabited island in the Colombian Caribbean, using an integrated analytical framework that...
