Neural representation of sensorimotor features in language-motor areas during auditory and visual perception.

Speech processing involves a complex interplay between sensory and motor systems in the brain, essential for early language development. Recent studies have extended this sensory-motor interaction to visual word processing, emphasizing the connection between reading and handwriting during literacy acquisition. Here we show how language-motor areas encode motoric and sensory features of language stimuli during auditory and visual perception, using functional magnetic resonance imaging (fMRI) combined with representational similarity analysis.

Ultrasound localization microscopy in the diagnosis of breast tumors and prediction of relevant histologic biomarkers associated with prognosis in humans: the protocol for a prospective, multicenter study.

Cilia-Mimic Locomotion of Magnetic Colloidal Collectives Enhanced by Low-Intensity Ultrasound for Thrombolytic Drug Penetration.

Rapid thrombolysis is very important to reduce complications caused by vascular blockage. A promising approach for improving thrombolysis efficiency is utilizing the permanent magnetically actuated locomotion of nanorobots. However, the thrombolytic drug transportation efficiency is challenged by in-plane rotating locomotion and the insufficient drug penetration limits further improvement of thrombolysis.

Magnetic nanoparticle-mediated non-invasive imaging and eradication of lymph nodes.

Regional lymph node (LN) dissection is often used for the treatment of deep LNs in tumour surgery; however, the method is prone to incomplete LN dissection, trauma, complications, and other side effects. LN tracers make it easier to visualise and remove LNs. However, the current common LN tracers only have a single function or have radiation hazards related to their use.

IL-10 mediates pleural remodeling in systemic lupus erythematosus.

Background: Interleukin-10 (IL-10), a pivotal anti-inflammatory cytokine, has gotten attention for its involvement in tissue remodeling and organ fibrosis. Pleurisy and subsequent pleural remodeling are recognized as quantifiable indicators of systemic lupus erythematosus (SLE) activity. However, the role of IL-10 in SLE-associated pleural remodeling remains unknown.

Non-invasive ultrasound localization microscopy (ULM) in azoospermia: connecting testicular microcirculation to spermatogenic functions.

Azoospermia is a significant reproductive challenge. Differentiating between non-obstructive azoospermia (NOA) and obstructive azoospermia (OA) is crucial as each type requires distinct management strategies. Testicular microcirculation plays a profound role in spermatogenic functions.

Temporal neural dynamics of understanding communicative intentions from speech prosody.

Understanding the correct intention of a speaker is critical for social interaction. Speech prosody is an important source for understanding speakers' intentions during verbal communication. However, the neural dynamics by which the human brain translates the prosodic cues into a mental representation of communicative intentions in real time remains unclear.

A Multi-Task Transformer With Local-Global Feature Interaction and Multiple Tumoral Region Guidance for Breast Cancer Diagnosis.

Breast cancer, as a malignant tumor disease, has maintained high incidence and mortality rates over the years. Ultrasonography is one of the primary methods for diagnosing early-stage breast cancer. However, correctly interpreting breast ultrasound images requires massive time from physicians with specialized knowledge and extensive experience.

Inhalable cardiac targeting peptide modified nanomedicine prevents pressure overload heart failure in male mice.

Heart failure causes considerable morbidity and mortality worldwide. Clinically applied drugs for the treatment of heart failure are still severely limited by poor delivery efficiency to the heart and off-target consumption. Inspired by the high heart delivery efficiency of inhaled drugs, we present an inhalable cardiac-targeting peptide (CTP)-modified calcium phosphate (CaP) nanoparticle for the delivery of TP-10, a selective inhibitor of PDE10A.

Metainterface Heterostructure Enhances Sonodynamic Therapy for Disrupting Secondary Biofilms.

Super-resolution imaging of urethral vasculature in healthy pre- and post-menopausal females.

Previous studies have postulated that the urethral vasculature (UV) might play an important role in urinary continence for women. The goal of this research was to compare the UV in pre- and post-menopausal women using a super-resolution ultrasound imaging method called Super Ultrasound for Greater Accuracy and Resolution (SUGAR). We found that post-menopausal women exhibited decreased UV parameters such as fractal dimension, vessel proportion, and mean blood vessel diameter than pre-menopausal women.

Lactic acid responsive sequential production of hydrogen peroxide and consumption of glutathione for enhanced ferroptosis tumor therapy.

Ferroptosis is characterized by the lethal accumulation of lipid reactive oxygen species (ROS), which has great potential for tumor therapy. However, developing new ferroptosis-inducing strategies by combining nanomaterials with small molecule inducers is important. In this study, an enzyme-gated biodegradable natural-product delivery system based on lactate oxidase (LOD)-gated biodegradable iridium (Ir)-doped hollow mesoporous organosilica nanoparticles (HMONs) loaded with honokiol (HNK) (HNK@Ir-HMONs-LOD, HIHL) is designed to enhance ferroptosis in colon tumor therapy.

Promoting collateral formation in type 2 diabetes mellitus using ultra-small nanodots with autophagy activation and ROS scavenging.

Background: Impaired collateral formation is a major factor contributing to poor prognosis in type 2 diabetes mellitus (T2DM) patients with atherosclerotic cardiovascular disease. However, the current pharmacological treatments for improving collateral formation remain unsatisfactory. The induction of endothelial autophagy and the elimination of reactive oxygen species (ROS) represent potential therapeutic targets for enhancing endothelial angiogenesis and facilitating collateral formation.
