Treatment for moyamoya disease with hyperhomocysteinemia.

This study aimed to investigate the impact of controlling serum homocysteine on improving surgical outcomes in patients with moyamoya disease (MMD) and hyperhomocysteinemia. In this prospective observational cohort study, 477 patients with MMD post-encephaloduroarteriosynangiosis are divided into the HHcy-MMD post-control group (n = 193), HHcy-MMD uncontrolled group (n = 91), and MMD group (n = 193), with the HHcy-MMD post-control group further subdivided into good (homocysteine 0-10 μmol/L, n = 121) and general (homocysteine 10-15 μmol/L, n = 72) control groups. The differences in imaging and long-term clinical prognosis among the three groups were compared.

Huangqi and Danshen improve the chronic nephrotoxicity of cyclosporin A by regulating lipid metabolism.

Background: The clinical application of cyclosporine A (CsA) is limited due to nephrotoxicity. Lipid metabolism disorders play important roles in renal injury, but their role in CsA nephrotoxicity is not yet clear. Huangqi (Astragalus mongholicus Bunge) and Danshen (Salvia miltiorrhiza Bunge) (HD) play roles in ameliorating the nephrotoxicity of CsA, but their mechanisms still need to be fully clarified.

Compatibility of Calycosin-Tanshinone IIA improves Ang II-induced renal artery endothelial cell dysfunction through lncRNA-mRNA co-expression network.

This study aimed to investigate the effect of the compatibility of Calycosin and Tanshinone IIA on dysfunction of rat renal artery endothelial cells (RRAECs) induced by angiotensin II (Ang II) and to elucidate the underlying molecular mechanisms. We utilized cell culture to optimize Calycosin and Tanshinone IIA concentrations and assessed autophagy, apoptosis, ATP levels, and cell migration using MDC staining, Annexin V-FITC/PI staining, ATP assay, and Transwell assays, respectively. RNA-seq identified differentially expressed lncRNAs and mRNAs, which were validated by qRT-PCR.

The gut-kidney axis is regulated by astragaloside IV to inhibit cyclosporine A-induced nephrotoxicity.

Introduction: Chronic nephrotoxicity caused by CNIs (CICN) manifests clinically as chronic kidney disease (CKD). Astragaloside IV (AS-IV) plays a certain role in the treatment of CKD. This study aimed to verify the ameliorative effects of AS-IV on CICN and further explore the mechanisms underlying the modulation of the "gut-transcriptome-metabolome coexpression network" by AS-IV within the context of the "gut-kidney axis" to improve CICN.

New method for cytological evaluation using direct nipple discharge without aspiration.

Conventional smear cytology (CSC) is a specific method used for breast tumor diagnosis in patients with nipple discharge. However, CSC tends to miss diagnose or even misdiagnose due to contaminating blood cells and other impurities. Thus, it is critical to develop more accurate and sensitive methods for clinical evaluation.

An improved U-net and attention mechanism-based model for sugar beet and weed segmentation.

Introduction: Weeds are a major factor affecting crop yield and quality. Accurate identification and localization of crops and weeds are essential for achieving automated weed management in precision agriculture, especially given the challenges in recognition accuracy and real-time processing in complex field environments. To address this issue, this paper proposes an efficient crop-weed segmentation model based on an improved UNet architecture and attention mechanisms to enhance both recognition accuracy and processing speed.

TdCCA with Dual-Modal Signal Fusion: Degenerated Occipital and Frontal Connectivity of Adult Moyamoya Disease for Early Identification.

Cognitive impairment in patients with moyamoya disease (MMD) manifests earlier than clinical symptoms. Early identification of brain connectivity changes is essential for uncovering the pathogenesis of cognitive impairment in MMD. We proposed a temporally driven canonical correlation analysis (TdCCA) method to achieve dual-modal synchronous information fusion from electroencephalogram (EEG) and functional near-infrared spectroscopy (fNIRS) for exploring the differences in brain connectivity between MMD and normal control groups.

2-Acetamidophenol (2-AAP) Suppresses the Progression of Atherosclerosis by Alleviating Hyperlipidemia and Attenuating the Ferroptosis Pathway.

Hyperlipidemia and consequent endothelial inflammation, along with foam cell generation, promote the progression of atherosclerosis (AS). Here, we aimed to investigate the effects of 2-acetamidophenol (2-AAP), which was selected by zebrafish phenotypic screening, in alleviating AS by relieving hyperlipidemia and inhibiting foam cell formation, as well as the underlying mechanisms. In a zebrafish hyperlipidemia model, 2-AAP increased lipid-lowering efficacy; alleviated TC, TG, LDL-C, and MDA levels; elevated HDL-C and T-SOD levels; significantly improved intravascular macrophage aggregation; and improved blood flow.

RRBM-YOLO: Research on Efficient and Lightweight Convolutional Neural Networks for Underground Coal Gangue Identification.

Coal gangue identification is the primary step in coal flow initial screening, which mainly faces problems such as low identification efficiency, complex algorithms, and high hardware requirements. In response to the above, this article proposes a new "hardware friendly" coal gangue image recognition algorithm, RRBM-YOLO, which is combined with dark light enhancement. Specifically, coal gangue image samples were customized in two scenarios: normal lighting and simulated underground lighting with poor lighting conditions.

Wnt5a negatively regulates melanogenesis in primary Arctic fox epidermal melanocytes.

Melanocytes, which are mainly found in the epidermis, are responsible for the melanin of skin and hair, and thereby contribute to the appearance of skin and provide protection from damage by ultraviolet radiation. Our previous study revealed that the Wnt5a, one of the many genes that affect melanin production, might be involved in the coat color seasonal change of the Arctic fox by influencing skin melanogenesis. Although the role of Wnt5a in melanocyte lines and melanoma cells has been extensively studied, its role in primary epidermal melanocytes has not been explored.

C-Reactive Protein Induces Immunosuppression by Activating FcγR2B in Pulmonary Macrophages to Promote Lung Metastasis.

C-reactive protein (CRP) is a liver-derived acute phase reactant that is a clinical marker of inflammation associated with poor cancer prognosis. Elevated CRP levels are observed in many types of cancer and are associated with significantly increased risk of metastasis, suggesting that CRP could have prometastatic actions. In this study, we reported that CRP promotes lung metastasis by dampening the anticancer capacity of pulmonary macrophages in breast cancer and melanoma.

Brain-Controlled Augmented Hearing for Spatially Moving Conversations in Multi-Talker Environments.

Focusing on a specific conversation amidst multiple interfering talkers is challenging, especially for those with hearing loss. Brain-controlled assistive hearing devices aim to alleviate this problem by enhancing the attended speech based on the listener's neural signals using auditory attention decoding (AAD). Departing from conventional AAD studies that relied on oversimplified scenarios with stationary talkers, a realistic AAD task that involves multiple talkers taking turns as they continuously move in space in background noise is presented.

EXPLORING SELF-SUPERVISED CONTRASTIVE LEARNING OF SPATIAL SOUND EVENT REPRESENTATION.

In this study, we present a simple multi-channel framework for contrastive learning (MC-SimCLR) to encode 'what' and 'where' of spatial audios. MC-SimCLR learns joint spectral and spatial representations from unlabeled spatial audios, thereby enhancing both event classification and sound localization in downstream tasks. At its core, we propose a multi-level data augmentation pipeline that augments different levels of audio features, including waveforms, Mel spectrograms, and generalized cross-correlation (GCC) features.
