Spatial Patterning of Modular Gelatin‐Peroxide Microspheres in Melt‐Electrowritten Scaffolds Provides Controlled Oxygen Generation and Mitigates Hypoxia and Cytotoxicity

open access: yesAdvanced Healthcare Materials, EarlyView.
A bioassembly approach is described using photo‐crosslinked gelatin‐based microgels containing calcium peroxide (CaO2) to generate oxygen (O2) and enhance cell survival in hypoxic conditions (1% O2). Bioassembly enables spatial patterning of individual CaO2‐laden and mesenchymal stem cell (MSC)‐laden microgels and allows for decoupling and mitigating ...

Il dono e l’offerta

open access: yesM@GM@
Il presente contributo si divide in due parti. Nella prima, si parte dal Saggio sul dono di Marcel Mauss, uscito giusto cent’anni fa, in cui l’autore studia le forme dello scambio nelle società antiche e d’interesse etnologico, comparandole con quelle ...

A Tri‐Culture Heart‐on‐a‐Chip Platform With iPSC‐Derived Cardiac Cells for Predictive Cardiotoxicity Testing

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents the first entirely isogenic heart‐on‐chip, unifying cardiomyocytes, fibroblasts, and endothelial cells from a single iPSC source. The platform reveals a critical biological insight: the endothelium actively shields cardiac tissue from drug‐induced toxicity, challenging the predictive accuracy of conventional, avascular models for ...

L’arte del donare: significanze singolari e plurali

open access: yesM@GM@
Per meglio mettere a fuoco l’aspetto fondamentale del dono e le sue significanze singolari e plurali, non ho potuto che partire da una delle affermazioni dell’Antropologo Marcel Mauss che, nel suo famoso saggio, illustra con estrema chiarezza il come, le

Effect of very low-density lipoproteins on lipid transfer in incubated serum

open access: yesJournal of Lipid Research, 1965
Incubation of human serum solutions low in glyceride content for 16 hr resulted in a net increase of cholesterol esters in all three major human serum lipoprotein classes, namely the very low-density lipoproteins of d < 1.006 (VLDL), low-density ...

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

open access: yesAdvanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

Lipid transfer between human serum high density lipoproteins and egg yolk lipoproteins in incubation mixtures

open access: yesJournal of Lipid Research, 1966
Ultracentrifugally isolated human serum high density lipoproteins of d 1.063-1.21 (HDL) were incubated with egg yolk lipoproteins of d < 1.006 for up to 24 hr at various concentrations. Transfer of HDL cholesterol esters to egg yolk lipoproteins occurred

A Soft Robotic Device for Targeted Massage Therapy of Residual Limbs

open access: yesAdvanced Robotics Research, EarlyView.
Residual limb edema after amputation can hinder recovery and delay prosthetic fitting. This study presents a soft‐robotic wearable device that delivers sequential compression through pneumatic McKibben actuators. By replicating the principles of manual lymphatic drainage, the device generates controlled mechanotherapeutic pressure patterns, providing a

Boron deficiency responses in maize (Zea mays L.) roots

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Boron (B) is an essential micronutrient for plants. Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize (Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet.

Embracing complexity: the post-secular pilgrimage of Eric-Emmanuel Schmitt

open access: yesScripta Instituti Donneriani Aboensis, 2010
This article deals with the phenomenon of pilgrimage as a personal transformative process; an exploration of spiritual space rather than a journey undertaken to a physical place.
