Background: Macrophages play a pivotal role in the development and recovery of acute lung injury (ALI), wherein their phenotypic differentiation and metabolic programming are orchestrated by mitochondria. Specifically, the mitochondrial calcium uniporter (MCU) regulates mitochondrial Ca (Ca) uptake and may bridge the metabolic reprogramming and functional regulation of immune cells. However, the precise mechanism on macrophages remains elusive.

Article Synopsis
  • The study compared the effectiveness and safety of two laser methods, Moses and Raykeen, for treating impacted upper ureteral stones in 72 patients using flexible ureteroscopic lithotripsy.
  • Results showed that the Moses laser had a shorter operative and lithotripsy time, but both methods had similar rates of successful stone removal and no significant complications.
  • The research concluded that both laser modes are effective, but the powdered mode of Raykeen may be more beneficial for treating these types of stones, as the ablation speed was linked to stone volume rather than density.

Microbot collectives can cooperate to accomplish complex tasks that are difficult for a single individual. However, various force-induced microbot collectives maintained by weak magnetic, light, and electric fields still face challenges such as unstable connections, the need for a continuous external stimuli source, and imprecise individual control. Here, we construct magnetic and light-driven ant microbot collectives capable of reconfiguring multiple assembled architectures with robustness.

Untethered miniature soft robots have significant application potentials in biomedical and industrial fields due to their space accessibility and safe human interaction. However, the lack of selective and forceful actuation is still challenging in revolutionizing and unleashing their versatility. Here, we propose a focused ultrasound-controlled phase transition strategy for achieving millimeter-level spatially selective actuation and Newton-level force of soft robots, which harnesses ultrasound-induced heating to trigger the phase transition inside the robot, enabling powerful actuation through inflation.

Currently, clinical practice and scientific research mostly revolve around a single disease or system, but the single disease-oriented diagnostic and therapeutic paradigm needs to be revised. This review describes how transcutaneous auricular vagus nerve stimulation (taVNS), a novel non-invasive neuromodulation approach, connects the central and peripheral systems of the body. Through stimulation of the widely distributed vagus nerve from the head to the abdominal cavity, this therapy can improve and treat central system disorders, peripheral system disorders, and central-peripheral comorbidities caused by autonomic dysfunction.

Inspired by the reverse thrust generated by fuel injection, micromachines that are self-propelled by bubble ejection are developed, such as microrods, microtubes, and microspheres. However, controlling bubble ejection sites to build micromachines with programmable actuation and further enabling mechanical transmission remain challenging. Here, bubble-propelled mechanical microsystems are constructed by proposing a multimaterial femtosecond laser processing method, consisting of direct laser writing and selective laser metal reduction.

Traumatic penumbra (TP) is a secondary injury area located around the core area of traumatic brain injury after brain trauma, and is an important factor affecting the outcome of traumatic brain injury (TBI). The main pathological change caused by TP is brain edema, including (cellular brain edema and vascular brain edema). The formation and development of brain edema in the TP area are closely related to the blood-brain barrier (BBB) and vascular endothelial growth factor (VEGF).
