The production of short-chain fatty acids (SCFAs) through anaerobic fermentation is a significant strategy for the resource utilization of excess sludge (ES). However, the limitations of low temperatures and slow ES hydrolysis rates have resulted in less than optimal volatile fatty acid (VFA) accumulation. This study reports a new method for improving ES low-temperature anaerobic fermentation for VFA production using peracetic acid (PAA) pretreatment and elucidates the underlying mechanisms.

As a crucial element of proteolysis targeting chimeras (PROTACs), the choice of E3 ubiquitin ligase significantly influences degradation efficacy and selectivity. However, the available arsenal of E3 ligases for PROTAC development remains underexplored, severely limiting the scope of targeted protein degradation. In this study, we identify a non-inhibitory aptamer targeting ZYG11B, a substrate receptor of the Cullin 2-RING ligase complex, as an E3 warhead for targeted protein degradation.

Myeloid cells play vital roles in homeostasis and immune responses in vertebrates, but the developmental pathway underlying their lineage diversity remains elusive. Here, we construct a single-cell transcriptional map of myeloid progenitors from mouse bone marrow and conduct cross-species and developmental analyses across human, monkey, mouse, and zebrafish. We uncover a conserved specification program separating the eosinophil-basophil-mast cell (EBM) lineage and neutrophil-monocyte (NM) lineage, reclassifying myeloid cells beyond the conventional granulocytic and monocytic framework.

Deep ultraviolet (DUV) photodetection usually relies on wide-bandgap semiconductors, which however face challenges in material growth and doping processes. In this work, we proposed and validated a photodetection scheme based on tunneling barrier modulation, achieving highly sensitive DUV photodetection. Using a two-dimensional van der Waals heterostructure, the device integrates MoS as the transporting layer for its high carrier mobility and low dark current, few-layered graphene (FLG) as the photon absorption layer, and hexagonal boron nitride (hBN) as the dielectric barrier.

Non-steroidal anti-inflammatory drugs (NSAIDs), widely used for their therapeutic benefits, are associated with significant gastrointestinal complications, including the rare occurrence of colonic diaphragm disease (CDD). Characterized by diaphragm-like fibrotic strictures that narrow the intestinal lumen, CDD often leads to symptoms such as chronic anemia, bowel obstruction, and gastrointestinal bleeding. This report discusses a case of NSAID-induced CDD in a 58-year-old male with a history of prolonged NSAID use for osteoarthritis.

Background: Although successful treatment of papillary craniopharyngiomas (PCPs) with BRAFv600e inhibitors has been reported in clinical trials, studies have shown that approximately 10% of PCPs lack the BRAFv600e mutation and that BRAFv600e inhibitors may not be significantly effective against these tumors. However, no studies have focused specifically on BRAFv600e PCPs.

Methods: Spatial transcriptome sequencing was performed on calcified PCP tissue to identify novel subtypes of PCP cells.

Millimeter-wave (mmWave) radar pointcloud offers attractive potential for 3D sensing, thanks to its robustness in challenging conditions such as smoke and low illumination. However, existing methods failed to simultaneously address the three main challenges in mmWave radar pointcloud reconstruction: specular information lost, low angular resolution, and severe interference. In this paper, we propose DREAM-PCD, a novel framework specifically designed for real-time 3D environment sensing that combines signal processing and deep learning methods into three well-designed components to tackle all three challenges: Non-Coherent Accumulation for dense points, Synthetic Aperture Accumulation for improved angular resolution, and Real-Denoise Multiframe network for interference removal.
