Intelligent Continuum Micromachines in Complex Confined Spaces

open access: yesSmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Biomaterial Platforms for Spatiotemporal Control of mRNA Delivery in Tissue Engineering and Regenerative Medicine: Design Rules, Therapeutic Applications, and Translational Roadmap

open access: yesSmall, EarlyView.
Biomaterial platforms can control where and when mRNA‐encoded proteins are expressed to support tissue repair. This Review proposes a cargo–target–timing framework linking therapeutic function, target tissues and cells, and expression profiles with carrier and scaffold design.

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

open access: yesIntegrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Use of combined chemotherapy and immunotherapy improves pulmonary arterial hypertension

open access: yesPulmonary Circulation
Treatment modalities for pulmonary arterial hypertension (PAH) improve quality of life and walk distance. However, none of these therapies alter the structural/functional pulmonary vascular integrity that results in vascular remodeling. PAH smooth muscle

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

open access: yesIntegrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Comparative Genomics and Functional Evidence for Convergent Adaptation to Hypoxia in Mammals

open access: yesIntegrative Zoology, EarlyView.
This study reveals convergent selection in mammals adapted to hypoxia. Functional assays demonstrate that amino acid mutations reduce oxidative stress, attenuate hypoxia‐induced injury, and modulate the hypoxia‐inducible transcription factor (HIF)‐driven hypoxic response.

Non‐canonical PKG1 regulation in cardiovascular health and disease

open access: yesBritish Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

Funktionelle Charakterisierung von Mitgliedern des MicroRNA-17-92-Clusters im Blutgefäßsystem [PDF]

open access: yes, 2011
Almost two decades ago, microRNAs were discovered as novel posttranscriptional regulators of gene expression. Since then, research efforts have uncovered their involvement in the control of various cellular processes including migration, proliferation ...

Endothelial-smooth muscle microgauges for modeling pulmonary arterial vasoregulation. [PDF]

open access: yes
Pulmonary arterial hypertension (PAH) is a devastating disease for which there is no cure. The pathogenesis of PAH involves endothelial dysfunction and dysregulation of vascular tone, resulting in progressively narrowing pulmonary arteries that increase ...
