Grip and Grasp: Lizard Claw Inspired Robotic Manipulators

Advanced Robotics Research, EarlyView.
Our study identifies the most effective lizard claw shape for use as an end effector in a bioinspired robotic manipulator. By examining key geometric features and combining them into comparative indices, the Crotaphytus collaris claw is found to be the best fit.

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

Advanced Science, EarlyView.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

Inhibition of SLC11A1‐Mediated Lysosomal Iron Accumulation in Microglia Promotes Repair Following White Matter Stroke

Advanced Science, EarlyView.
Genetic and pharmacological inhibition of SLC11A1 functioning as an H+/Fe2+ antiporter–mediated lysosomal iron accumulation in microglia promotes lysosomal lumen acidification, increases CTSD expression, enhances lysosomal myelin debris uptake and degradation, and promotes repair following white matter stroke. ABSTRACT White matter stroke (WMS) results

Possibilities of Application of Relative Openness in Secondary Forest Opening of Slope Forests in Croatia

Croatian Journal of Forest Engineering, 2011
For achieving a high-quality and efficient management of forest ecosystems (Pentek et al. 2010), it is necessary to provide an optimally distributed network of primary and secondary forest road infrastructure.

Managing Forests for Water Quality: Forest Roads

, 2004
Access to privately owned forest land is necessary for many reasons: forest management activities such as site preparation, planting, and harvesting; recreational activities such as hunting, fi shing, hiking and camping; fi re suppression; and access to home or cabin sites.

Engineered GM1 Intersects Between Mitochondrial and Synaptic Pathways to Ameliorate ALS Pathology

Advanced Science, EarlyView.
Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease driven by genetic and molecular disruptions affecting energy balance, protein homeostasis, and stress responses in nerve cells. Studies using human and rodent models identified convergent defects in mitochondria and synaptic function.

Targeted Extracellular Vesicles Deliver Asiaticoside to Inhibit AURKB/DRP1‐Mediated Mitochondrial Fission and Attenuate Hypertrophic Scar Formation

Advanced Science, EarlyView.
Hypertrophic scar formation is driven by excessive mitochondrial fission in wound macrophages, which we discover is governed by a novel AURKB‐DRP1(Ser616) axis. The study develops a targeted therapy using cRGD‐decorated extracellular vesicles to deliver the natural compound Asiaticoside specifically to macrophages.

Optimization of the skid roads network

Glasnik Šumarskog Fakulteta Univerziteta u Banjoj Luci
Optimization of the skid roads network is a critical aspect of planning forest harvesting operations, as timber transport (including extraction and long-distance road transport) represents the most expensive stage of timber production. This task entails
