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 ...

Mitigating the water footprint of export cut flowers from the Lake Naivasha Basin, Kenya [PDF]

open access: yes, 2010
Kenya’s cut-flower industry has been praised as an economic success as it contributed an annual average of US$ 141 million foreign exchange (7% of Kenyan export value) over the period 1996-2005 and about US$ 352 million in 2005 alone.

A Biomimetic Buffering Hydrogel Scaffold for Long‐Term Culture of Patient‐Derived Tumor Organoids

open access: yesAdvanced Healthcare Materials, EarlyView.
A biomimetic fibrous buffering hydrogel controls the local acidification at the tumoroid/hydrogel interface at the physiologically relevant level over 21‐day culture. The buffering effect promotes cancer cell proliferation in the tumoroids and supports the structural integrity and mechanical properties of the hydrogel scaffold over long‐term tumoroid ...

A Flower Sanctuary [PDF]

open access: yesNature, 1912
I BEG to thank Mr. Perrycoste for his letter in NATURE of September 19. The county of Somerset has for some time had a by-law similar to that of the county of Cornwall; but you will observe that the by-law does not justify the protection of any particular plant, and that the special flora of Cheddar might easily disappear without any violation of its ...

siRNA Delivery via Cross‐Linked Gelatin Microparticles Enables Targeted Modulation of Osteogenic‐Vascular Cross‐Talk: An Advanced Human 3D in Vitro Test System for Therapeutic siRNA

open access: yesAdvanced Healthcare Materials, EarlyView.
Osteogenic‐angiogenic cross‐talk is a vital prerequisite for vascularized bone regeneration. In this study, we investigated the effects of siRNA‐mediated silencing of two inhibitory proteins, Chordin and WWP‐1, via CaP‐NP‐loaded gelatin microparticles in osteogenically differentiated microtissues.

Two Material Properties from One Wavelength‐Orthogonal Photoresin Enabled by a Monochromatic Laser Integrated Stereolithographic Apparatus (Mono LISA)

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
A single object with dual properties – degradable and non‐degradable – is fabricated in a single print simply by switching the printing colors. The advanced multi‐material printing is enabled by the combination of a fully wavelength‐orthogonal photoresin and a monochromatic tunable laser printer, paving the way for precise multi‐material ...

Fostering Health Education With a Serious Game in Children With Asthma: Pilot Studies for Assessing Learning Efficacy and Automatized Learning Personalization

open access: yesFrontiers in Education, 2018
Coupled with Health Education programs, an e-learning platform—KidBreath—was participatory designed and assessed in situ (Study 1) and was augmented and tested with an Intelligent Tutoring System (ITS) based on Multi-Armed Bandit Methods (Study 2).
