Neuromodulation techniques for modulating cognitive function: enhancing stimulation precision and intervention effects.

Neuromodulation techniques effectively intervene in cognitive function, holding considerable scientific and practical value in fields such as aerospace, medicine, life sciences, and brain research. These techniques utilize electrical stimulation to directly or indirectly target specific brain regions, modulating neural activity and influencing broader brain networks, thereby regulating cognitive function. Regulating cognitive function involves an understanding of aspects such as perception, learning and memory, attention, spatial cognition, and physical function.

Molecular basis of lipid and ligand regulation of prostaglandin receptor DP2.

Prostaglandin D2 receptor 2 (DP2) is an important anti-inflammatory and antiallergic drug target. While inactive DP2 structures are known, its activation mechanisms and biased signaling remain unclear. Here, we report cryo-EM structures of an apo DP2-Gi complex, a DP2-Gi complex bound to the endogenous ligand Prostaglandin D (PGD), and a DP2-Gi complex bound to indomethacin, an arrestin-biased ligand, at resolutions of 2.

Advanced Piezoelectric Materials, Devices, and Systems for Orthopedic Medicine.

Harnessing the robust electromechanical couplings, piezoelectric materials not only enable efficient bio-energy harvesting, physiological sensing and actuating but also open enormous opportunities for therapeutic treatments through surface polarization directly interacting with electroactive cells, tissues, and organs. Known for its highly oriented and hierarchical structure, collagen in natural bones produces local electrical signals to stimulate osteoblasts and promote bone formation, inspiring the application of piezoelectric materials in orthopedic medicine. Recent studies showed that piezoelectricity can impact microenvironments by regulating molecular sensors including ion channels, cytoskeletal elements, cell adhesion proteins, and other signaling pathways.

A phosphoglycerate mutase 1 allosteric inhibitor restrains TAM-mediated colon cancer progression.

Colorectal cancer (CRC) is a prevalent malignant tumor often leading to liver metastasis and mortality. Despite some success with PD-1/PD-L1 immunotherapy, the response rate for colon cancer patients remains relatively low. This is closely related to the immunosuppressive tumor microenvironment mediated by tumor-associated macrophages (TAMs).

Living biobank: Standardization of organoid construction and challenges.

In multiple areas such as science, technology, and economic activities, it is necessary to unify the management of repetitive tasks or concepts by standardization to obtain the best order and high efficiency. Organoids, as living tissue models, have rapidly developed in the past decade. Organoids can be used repetitively for in vitro culture, cryopreservation, and recovery for further utilization.

π-HuB: the proteomic navigator of the human body.

The human body contains trillions of cells, classified into specific cell types, with diverse morphologies and functions. In addition, cells of the same type can assume different states within an individual's body during their lifetime. Understanding the complexities of the proteome in the context of a human organism and its many potential states is a necessary requirement to understanding human biology, but these complexities can neither be predicted from the genome, nor have they been systematically measurable with available technologies.

Accelerated T2W Imaging with Deep Learning Reconstruction in Staging Rectal Cancer: A Preliminary Study.

Deep learning reconstruction (DLR) has exhibited potential in saving scan time. There is limited research on the evaluation of accelerated acquisition with DLR in staging rectal cancers. Our first objective was to explore the best DLR level in saving time through phantom experiments.

Belumosudil in pediatric patients with chronic graft-versus-host disease after failed multi-line therapy: a case series.

Belumosudil is a selective small molecule inhibitor of Rho-associated coiled-coil kinase 2 (ROCK2) indicated for patients with glucocorticoid-refractory chronic graft-versus-host disease (cGVHD). Despite its approval for ages 12-18, there is limited pediatric data available. This case series presents three 12-year-old patients with severe cGVHD who had failed multiple lines of therapy.

FOLFOX-HAIC combined with targeted immunotherapy for initially unresectable hepatocellular carcinoma: a real-world study.

Background: Hepatic arterial infusion chemotherapy (HAIC) with the FOLFOX regimen has demonstrated efficacy in patients with unresectable hepatocellular carcinoma (HCC). The combined targeted and immunotherapy has emerged as a first-line treatment for liver cancer. In this study, we investigated the clinical efficacy and safety of FOLFOX-HAIC in combination with targeted immunotherapy in patients with untreated, unresectable HCC.

Comparative evaluation of SanAgileSA01 ultrasonic scalpel and Johnson & Johnson GEN11, and HAR36 for efficacy and safety.

Background: The advent of ultrasonic scalpels has remarkably advanced minimally invasive surgery; however, the Chinese market's reliance on imports highlights the urgent need for a cost-effective, efficient, and domestically produced surgical scalpel. This study aimed to compare SanAgileSA01 with the Johnson & Johnson GEN11, and HAR36 surgical devices.

Research Design And Methods: In total, 152 participants requiring urological or general laparoscopic surgery were randomly and equally divided between the two hospitals and randomized to the test and control groups.

Precise Cell Type Electrical Stimulation Therapy Via Force-electric Hydrogel Microspheres for Cartilage Healing.

Electrical stimulation enhances cellular activity, promoting tissue regeneration and repair. However, specific cells and maintaining a stable energy supply are challenges for precise cell electrical stimulation therapy. Here, force-electric conversion hydrogel microspheres (Piezo@CR MPs) is devloped to induce specific stem cell aggregation and promote chondrogenic differentiation through localized electrical stimulation.

Dural metastases in breast cancer: progression pattern, treatment and prognosis-a single center experience.

Background: Dural metastasis (DM) remains one of the most challenging clinical scenarios in breast cancer treatment. To date, no clear standard care of dural metastases has been established. We sought to identify the progression pattern or treatment strategies that could possibly improve prognosis of breast cancer patients with DM.

Prognostic Value of Coronary CT Angiography-Derived Quantitative Flow Ratio in Suspected Coronary Artery Disease.

Background The prognostic value of coronary CT angiography (CTA)-derived quantitative flow ratio (CT-QFR) remains unknown. Purpose To determine the prognostic value of CT-QFR in predicting the long-term outcomes of patients with suspected coronary artery disease (CAD) in comparison with invasive coronary angiography (ICA)/SPECT and to determine the influence of prior percutaneous coronary intervention (PCI) on the prognostic value of CT-QFR. Materials and Methods In this secondary analysis of the prospective international CORE320 study, 379 participants who underwent coronary CTA and SPECT within 60 days before ICA between November 2009 and July 2011 were included for follow-up.

Racial and regional disparities in the risk of noncommunicable disease between sub-Saharan black and European white patients.

Objectives: Greater vulnerability of Black vs. White individuals to cardiovascular disease (CVD) and chronic kidney disease (CKD) is well charted in the United States, but studies involving sub-Saharan blacks are scarce.

Methods: Baseline data (2021-2024) were collected in 168 sub-Saharan Blacks and 93 European Whites in an ongoing clinical trial (NCT04299529), using standardized patient selection criteria.

Biosafety and efficacy evaluation of a biodegradable Zn-Cu-Mn stent: A long-term study in porcine coronary artery.

In this study, biodegradable Zn-Cu-Mn alloy stents were implanted into porcine coronary artery for 18 months, and the in vivo biosafety and efficacy as well as the degradation behavior were systematically studied. Results showed a rapid endothelialization of the target vessel was achieved at 1 month post-implantation. Although the lumen diameter loss and local inflammation were observed at the early stage, the stented blood vessel could gradually recover with time.
