Wireless In Situ Catalytic Electron Signaling‐Mediated Transcriptomic Reprogramming for Neuron Regeneration via Adaptable Antennas

Advanced Science, EarlyView.
A wireless‐charging sustained oxygen release from conductive microgels (SOCO) served as an antenna and an on‐demand O2 release for nerve regeneration is developed. Introducing “electromagnetic messenger”, using external alternating magnetic field (AMF) to enhance catalytic oxygen release and electrical stimulation to promote the reconstruction of blood

Learning Disease State from Noisy Ordinal Disease Progression Labels [PDF]

arXiv
Learning from noisy ordinal labels is a key challenge in medical imaging. In this work, we ask whether ordinal disease progression labels (better, worse, or stable) can be used to learn a representation allowing to classify disease state. For neovascular age-related macular degeneration (nAMD), we cast the problem of modeling disease progression ...

Effect of Bazi Bushen Capsule on D‐Galactose‐Induced Human Endothelial Cell Senescence Through PI3K/Akt/eNOS Signaling Pathway

AGING MEDICINE, EarlyView.
Bazi Bushen capsule (BZBS) is an over‐the‐counter drug approved by China FDA with the function of nourishing the kidney, replenishing essence, and combating aging. In this study, we concluded that the PI3K/AKT/eNOS signaling pathway contributed to BZBS repair of endothelial dysfunctions induced by D‐galactose.

Nozzle Jamming Granularized Blood‐Derived Proteins for Bioprinting Cell‐Instructive Architectures

Aggregate, EarlyView.
This work describes an innovative strategy to transform blood‐derived materials into highly printable granular materials that can be used as cell‐instructive bioinks by applying nozzle jamming instead of conventional centrifugal jamming. These modular inks allowed for increased microporosity in large 3D‐printed constructs, biocompatibility, and drug ...

Brant-X: A Unified Physiological Signal Alignment Framework [PDF]

SIGKDD 2024
Physiological signals serve as indispensable clues for understanding various physiological states of human bodies. Most existing works have focused on a single type of physiological signals for a range of application scenarios. However, as the body is a holistic biological system, the inherent interconnection among various physiological data should not

Simultaneous Determination of Nitrite and Nitrate in Milk Samples by Ion Chromatography Method and Estimation of Dietary Intake [PDF]

, 2016
The presence of nitrate and nitrite in foods may be considered hazardous after ingestion in the gastrointestinal tract due to their reaction with naturally occurred secondary amines to form potentially carcinogenic nitrosamines.

Hydrogel‐Based Smart Materials for Wound Healing and Sensing

Aggregate, EarlyView.
The graphical abstract illustrates the role of hydrogel‐based flexible materials in advancing biomedical applications, including wound healing, point‐of‐care diagnostics, smart patches, and wearable devices. Hydrogels are particularly promising in modern wound care due to their high‐water content, flexibility, and biocompatibility.

Biocompatibility and healing patterns in experimentally induced canine tibial fractures using Pedicle screw‐Rod external fixation

Animal Models and Experimental Medicine, EarlyView.
This study demonstrates that using a Pedicle screw‐Rod configuration for the external fixation of non‐articular tibial osteotomy aligns well with the principles of biological osteosynthesis, resulting in secondary bone healing characterized by callus formation and neovascularization.

Exploring the Optimal Time Window for Predicting Cognitive Load Using Physiological Sensor Data [PDF]

arXiv
Learning analytics has begun to use physiological signals because these have been linked with learners' cognitive and affective states. These signals, when interpreted through machine learning techniques, offer a nuanced understanding of the temporal dynamics of student learning experiences and processes.
