Electrical conductivity is a critical biomarker for cellular activity and a fundamental parameter in material science. However, achieving label-free, contact-free conductivity measurements with optical-scale resolution remains a challenge. Here, we introduce a magneto-photoacoustic coupling effect that enables conductivity mapping through photoacoustic excitation in the presence of a static magnetic field.

The quality of wine largely depends on the quality of wine grapes, which is determined by their chemical composition. Therefore, measuring parameters related to grape ripeness, such as soluble solids content (SSC), is crucial for harvesting high-quality grapes. Visible-Near-Infrared (Vis/NIR) spectroscopy enables effective, non-destructive detection of SSC in grapes.

Cross-domain image segmentation plays a crucial role in the field of remote sensing. Current approaches often rely on a mean-teacher model that is integrated from student models to guide the training of the student model itself. However, the feature space of the mean-teacher model exhibits significant domain discrepancy and considerable class overlap, which results in suboptimal performance.

The human placenta is a unique organ that forms under specific physiological conditions and plays a crucial role in nutrient and metabolite exchange between the mother and fetus. Research on the placenta is important for understanding maternal-fetal diseases. Traditionally, the placenta was considered "sterile," but advancements in detection techniques have revealed the presence of a low level of microorganisms.

Background: This study aimed to explore the characteristics of appearance-related distress and the relationship between appearance-related distress, anxiety and depression symptoms in Chinese patients with cleft lip (CL).
Methods: The Derriford Appearance Scale 59 (DAS-59), Generalized Anxiety Disorder-7 (GAD-7), and Patient Health Questionnaire-9 (PHQ-9) were used to screen for appearance-related distress, anxiety, and depression symptoms in Chinese patients with CL, respectively.
Results: A total of 63 patients with CL, comprising 43 unilateral and 20 bilateral cases, and 64 individuals without CL in the control group were included in the study.
Proper regulation of intestinal permeability is essential for maintaining the integrity of the intestinal mucosal barrier. An abnormal increase in permeability can significantly contribute to the onset and progression of various diseases, including autoimmune disorders, metabolic conditions, allergies, and inflammatory bowel diseases. The potential connection between intestinal permeability and maternal health during pregnancy is increasingly recognized, yet a comprehensive review remains lacking.

Photoacoustic imaging (PAI) can sensitively detect regions and substances with strong optical absorption, which means that diseased tissue can be imaged with high contrast in the presence of surrounding healthy tissue through the photoacoustic effect. However, its signal intensity and resolution may be limited by background signals generated by endogenous chromophores such as melanin and hemoglobin. A feasible method for practical application of this so-called background-suppressed PAI is still lacking.

In this study, we utilized PP-PAT for the first time, to the best of our knowledge, to monitor the dynamics of oxygen partial pressure (pO) within murine tumors during photodynamic therapy (PDT) with methylene blue (MB). We developed, to our knowledge, a novel two-step fitting method to simultaneously map both the pO and the MB concentrations and implemented it with mexCuda to accelerate the pixel-wise-based calculation.

In this study, the gut microbiota from high-AFD chickens was transplanted into the same strain of 0-day-old chicks via fecal microbiota transplantation (FMT). The FTM from chickens with high AFD had no obvious effects on growth traits, adult body weight, carcass weight, abdominal fat weight, and abdominal fat percentage, but did reduce the coefficient of variation of AFD traits.

Real-time semantic segmentation plays an important role in auto vehicles. However, most real-time small object segmentation methods fail to obtain satisfactory performance on small objects, such as cars and sign symbols, since the large objects usually tend to devote more to the segmentation result. To solve this issue, we propose an efficient and effective architecture, termed small objects segmentation network (SOSNet), to improve the segmentation performance of small objects.

Epigenetic regulations, primarily including DNA and RNA methylation, histone modification and non-coding RNA, have been generally recognized as an essential feature of tumor malignancy, exceedingly contributing to the dysregulation of the core gene expression in neoplastic cells, bringing about the evasion of immunosurveillance by influencing the immune cells in TME. Recently, compelling evidence have highlighted that clinical therapeutic approaches based on epigenetic machinery modulate carcinogenesis through targeting TME components, including normalizing cells' phenotype, suppressing cells' neovascularization and repressing the immunosuppressive components in TME.

Hyperspectral image (HSI) classification methods have made great progress in recent years. However, most of these methods are rooted in the closed-set assumption that the class distribution in the training and testing stages is consistent, which cannot handle the unknown class in open-world scenes. In this work, we propose a feature consistency-based prototype network (FCPN) for open-set HSI classification, which is composed of three steps.

Regeneration of bone defects is a significant challenge today. As alternative approaches to the autologous bone, scaffold materials have remarkable features in treating bone defects; however, the various properties of current scaffold materials still fall short of expectations. Due to the osteogenic capability of alkaline earth metals, their application in scaffold materials has become an effective approach to improving their properties.

The transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) and its negative regulator kelch-like ECH-associated protein 1 (KEAP1) regulate various genes involved in redox homeostasis, which protects cells from stress conditions such as reactive oxygen species and therefore exerts beneficial effects on suppression of carcinogenesis. In addition to their pivotal role in cellular physiology, accumulating innovative studies indicated that NRF2/KEAP1-governed pathways may conversely be oncogenic and cause therapy resistance, which was profoundly modulated by epigenetic mechanism. Therefore, targeting epigenetic regulation in NRF2/KEAP1 signaling is a potential strategy for cancer treatment.
