Extrusion‐Based Bioprinting of Living Bioinks for Tissue and Organ Engineering

Advanced Materials Technologies, EarlyView.
Extrusion‐based bioprinting is presented as the most versatile route for fabricating living, heterogeneous tissues. Its ability to combine diverse bioinks, support matrices, and advanced printhead geometries transforms familiar constraints into powerful biofabrication opportunities.

Pre‐Regenerative Endothelial Cells Empowered by Antler Blood Exosomes Orchestrate Peripheral Nerve Repair

Advanced Science, EarlyView.
The pre‐regenerative vascular niche (PVN) is essential for nerve repair, yet its endothelial blueprint remains unclear. We identified angiogenic ECs (AECs) as the dominant pre‐regenerative subset and found that antler blood–derived exosomes (AB‐EXO) promote repair via IMP3.

A note on umbilic points at infinity

Beiträge zur Algebra und Geometrie / Contributions to Algebra and Geometry
Abstract In this note a definition of umbilic point at infinity is proposed, at least for surfaces that are homogeneous polynomial graphs over a plane in Euclidean 3-space. This is a stronger definition than that of Toponogov in his study of complete convex surfaces, and allows one to distinguish between different umbilic points at infinity ...

Co‐Delivery of Sustained Release Chondroitinase ABC‐37 With Human iPSC‐Derived Neural Progenitors Promotes Transplant Survival and Functional Recovery in a Rodent Model of Stroke

Advanced Science, EarlyView.
A regenerative strategy for stroke combines human stem cell–derived neural progenitor cells with sustained release of a matrix‐modifying, thermostable chondroitinase ABC‐37 enzyme. In a rat model of stroke, co‐delivery enhanced transplanted cell survival and neuronal differentiation, degraded inhibitory extracellular matrix components, and improved ...

Initial closed trocar entry for laparoscopic surgery: Technique, umbilical cosmesis, and patient satisfaction

Gynecology and Minimally Invasive Therapy, 2017
Background/Aims: Despite the benefits of laparoscopic surgery, which is being performed with increasing frequency, complications that do not occur during laparotomy are sometimes encountered.

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

A pedagogical view of migration phenomenology

Encyclopaideia, 2020
Starting from the interpretations of the philosophy of history that have sought a paradigmatic place, capable of representing a nodal point, an umbilical cord between cultures and civilizations, like a reality characterized by crossings and plurality ...

Normal umbilical artery doppler values in 18–22 week old fetuses with single umbilical artery

Scientific Reports, 2023
Umbilical cord with a single umbilical artery (SUA) can carry twice the blood volume of a three-vessel cord (TVC). So, the normal hemodynamics of the fetuses with SUA was different from those with TVC.
