Life after shock: the mission from Mars to Earth [PDF]

open access: yes, 2006
Extract from introduction: The minerals of the Martian meteorites collected so far indicate an exposure to shock waves in the pressure range of 5 to 55 GPa [1].

Soil Microbial Biomass And Activity In A Cork Oak Savanna [PDF]

open access: yes, 2010
Cork oak savannas are composed by a sparse tree canopy (30-70 trees/ha) and a grassland understory predominantly composed of C3 annuals that survive the hot and dry Mediterranean summers as seeds in the soil.

Human Brain Vasculature‐on‐a‐Chip Model Constructed With Microvessels Isolated From Cryopreserved Postmortem Human Brain Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
This manuscript describes the cultivation of viable microvessels from cryopreserved human brain tissue. When embedded in hydrogels and cultured in microfluidic devices, these microvessels exhibit complex architectures reminiscent of arterioles and capillaries, can be perfused, and display intact barrier function. Collectively, these results demonstrate

Characterization of the First “Candidatus Nitrotoga” Isolate Reveals Metabolic Versatility and Separate Evolution of Widespread Nitrite-Oxidizing Bacteria

open access: yesmBio, 2018
Nitrification is a key process of the biogeochemical nitrogen cycle and of biological wastewater treatment. The second step, nitrite oxidation to nitrate, is catalyzed by phylogenetically diverse, chemolithoautotrophic nitrite-oxidizing bacteria (NOB ...

Draft Genome of Janthinobacterium sp. RA13 Isolated from Lake Washington Sediment. [PDF]

open access: yes, 2015
Sequencing the genome of Janthinobacterium sp. RA13 from Lake Washington sediment is announced. From the genome content, a versatile life-style is predicted, but not bona fide methylotrophy.

3D‐Printed Gastrointestinal Stents: In Vivo Evaluation in a Swine Small Bowel Perforation Model

open access: yesAdvanced Healthcare Materials, EarlyView.
Gastrointestinal fistulae and perforations can lead to severe complications including sepsis and patient death. In this work, the efficacy of 3D‐printed gastrointestinal stents composed of poly‐lactic‐acid (PLA) was evaluated in an in vivo swine model.

The Impacts of Triclosan on Anaerobic Community Structures, Function, and Antimicrobial Resistance [PDF]

open access: yes, 1999
Triclosan is a widespread antimicrobial agent that accumulates in anaerobic digesters used to treat the residual solids generated at municipal wastewater treatment plants; there is very little information, however, about how triclosan impacts microbial ...

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

open access: yesAdvanced Healthcare Materials, EarlyView.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Bioreactor Scalability: Laboratory-Scale Bioreactor Design Influences Performance, Ecology, and Community Physiology in Expanded Granular Sludge Bed Bioreactors

open access: yesFrontiers in Microbiology, 2017
Studies investigating the feasibility of new, or improved, biotechnologies, such as wastewater treatment digesters, inevitably start with laboratory-scale trials.

Oxygen and ROS Delivery for Infected Wound Healing and Future Prospects

open access: yesAdvanced Healthcare Materials, EarlyView.
Bacterial infection is a major driver of delayed wound healing and postsurgical readmissions; with rising antibiotic resistance, solid peroxide–releasing biomaterials offer sustained delivery of ROS/O2 for antimicrobial control and microenvironmental modulation.
