The zinc oxide nanoparticles (ZnO NPs) is one of the most extensively utilized metal oxide nanoparticles in biomedicine, human food, cosmetics and livestock farming. However, growing evidence suggests that there is a potential risk for humans and animals because of the accumulation of ZnO NPs in cells, which leads to cell death through several different pathways. Nevertheless, the effects of ZnO NPs on porcine granulosa cells (PGCs) and how ZnO NPs regulate the follicular cells are unknown.

The escalating threat of healthcare-associated infections highlights the urgent need for biocompatible antibacterial materials that effectively combat drug-resistant pathogens. In this study, we present a novel fabrication method for triple-helical recombinant collagen (THRC)-silver hybrid nanofibers, specifically designed for anti-methicillin-resistant(MRSA) applications. Utilizing a silver-mediated crosslinking strategy, we harness a low-power 38 W lamp to enable silver ions (Ag) to mediate crosslinking across various proteins.

Article Synopsis
  • - The rate of complications is highest in patients with TE (tumor excision) who underwent radiation, followed by those with PI (partial irradiation), and is lowest in patients with AT (the specific type isn't defined).
  • - Using hypofractionation (a radiation therapy method) in patients with any type of IBR (indicating breast reconstruction) does not lead to a higher rate of complications compared to standard fractionation methods.
  • - The study's results could encourage the broader use of hypofractionated radiation therapy after breast reconstruction.

Background: Although the prognosis of triple-negative breast cancer (TNBC) has significantly improved in the era of immunotherapy, many TNBC patients are resistant to therapies, and their disease progresses rapidly. Deciphering the metabolic mechanisms regulating anticancer immunity will provide new insights into therapeutic strategies for TNBC.

Methods: In this study, we performed bioinformatics analysis in our multi-omics TNBC database and identified that a metabolic enzyme, dihydrodiol dehydrogenase (DHDH), might promote the phenotype of "cold tumor" in TNBC.

Trehalose, as a food and feed additive, can regulate physiological and pathological processes by activating autophagy, yet the molecular mechanism of trehalose dominated a rise in autophagy has not been elucidated. This study investigated the mechanisms of trehalose-induced autophagy in porcine granulosa cells (PGCs). Trehalose was internalized into PGCs by endocytosis and caused a temporary change of the lysosome pH, ultimately inducing autophagy.

Article Synopsis
  • * A meta-transcriptomics approach was used to assess virus composition and removal efficiency in two treatment systems, revealing a total of 172 viruses, with the chemical oxidation method (TCO) shown to reduce viral abundance, especially among RNA viruses.
  • * Despite increased efficiency in reducing viral numbers, pathogenic viruses such as PEDV and PRRSV remained present in the effluent, with environmental factors like pond temperature identified as significant influences on viral community variations.

Deep learning-based denoising of low-dose medical CT images has received great attention both from academic researchers and physicians in recent years, and has shown important application value in clinical practice. In this work, a novel two-branch and multi-scale residual attention-based network for low-dose CT image denoising is proposed. It adopts a two-branch framework structure, to extract and fuse image features at shallow and deep levels respectively, to recover image texture and structure information as much as possible.

Heatmap-based cattle pose estimation methods suffer from high network complexity and low detection speed. Addressing the issue of cattle pose estimation for complex scenarios without heatmaps, an end-to-end, lightweight cattle pose estimation network utilizing a reparameterized network and an attention mechanism is proposed to improve the overall network performance. The EfficientRepBiPAN (Efficient Representation Bi-Directional Progressive Attention Network) module, incorporated into the neck network, adeptly captures target features across various scales while also mitigating model redundancy.

Article Synopsis
  • A phase II trial was conducted to evaluate the efficacy and safety of a new neoadjuvant chemoimmunotherapy regimen combining chemotherapy with the PD-1 antibody toripalimab for early-stage triple-negative breast cancer (TNBC).
  • The study included 70 female patients with stage II-III TNBC, who received a combination of standard chemotherapy and immunotherapy, with primary endpoints focusing on total and breast pathological complete response rates.
  • Results showed that over half of the participants achieved tumor response, with some experiencing manageable side effects, indicating that this treatment combination is promising and worthy of further research.

Two-dimensional (2D) hybrid organic-inorganic metal halide perovskites offer enhanced stability for perovskite-based applications. Their crystal structure's soft and ionic nature gives rise to strong interaction between charge carriers and ionic rearrangements. Here, we investigate the interaction of photogenerated electrons and ionic polarizations in single-crystal 2D perovskite butylammonium lead iodide (BAPI), varying the inorganic lamellae thickness in the 2D single crystals.

Background: Zinc oxide nanoparticle (ZnO NP) is one of the metal nanomaterials with extensive use in many fields such as feed additive and textile, which is an emerging threat to human health due to widely distributed in the environment. Thus, there is an urgent need to understand the toxic effects associated with ZnO NPs. Although previous studies have found accumulation of ZnO NPs in testis, the molecular mechanism of ZnO NPs dominated a decline in male fertility have not been elucidated.

Article Synopsis
  • The study aims to evaluate how effective breast MRI is for identifying benign or malignant cases among women with BI-RADS 4A microcalcifications on mammograms, with a goal of reducing unnecessary biopsies.
  • Researchers analyzed data from 139 women and found that 82.4% of cases were benign, with MRI showing a positive predictive value of 44.2% and a specificity of 75.2%.
  • A proposed clinical pathway suggests that premenopausal women without a breast cancer history and with non-clustered microcalcifications could use MRI to avoid unnecessary biopsies, potentially missing only a small percentage of malignant cases.

Conventional food production is restricted by energy conversion efficiency of natural photosynthesis and demand for natural resources. Solar-driven artificial food synthesis from CO provides an intriguing approach to overcome the limitations of natural photosynthesis while promoting carbon-neutral economy, however, it remains very challenging. Here, we report the design of a hybrid electrocatalytic-biocatalytic flow system, coupling photovoltaics-powered electrocatalysis (CO to formate) with five-enzyme cascade platform (formate to sugar) engineered via genetic mutation and bioinformatics, which achieves conversion of CO to C sugar (L-sorbose) with a solar-to-food energy conversion efficiency of 3.

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system (CNS) mediated by immune cells, in which auto-reactive CD4 T cells have been implicated as a major driver in the pathogenesis of the disease. In this study, we aimed to investigate whether the artemisinin derivative TPN10475 could alleviate experimental autoimmune encephalomyelitis (EAE), a commonly used animal model of MS and its possible mechanisms. TPN10475 effectively resisted the reduction of TGF-β signal transduction induced by TCR stimulation, suppressed the activation and function of effector CD4 T cells in vitro, and restricted the differentiation of pathogenic Th1 and Th17 cells.

Triple-negative breast cancer (TNBC) is the most lethal subtype of breast cancer with no targeted therapy. Spermatid perinuclear RNA binding protein (STRBP), a poorly characterized RNA-binding protein (RBP), has an essential role in normal spermatogenesis and sperm function, but whether and how its dysregulation contributing to cancer progression has not yet been explored. Here, we report that STRBP functions as a novel oncogene to drive TNBC progression.

Background: Triple-negative breast cancers display heterogeneity in molecular drivers and immune traits. We previously classified triple-negative breast cancers into four subtypes: luminal androgen receptor (LAR), immunomodulatory, basal-like immune-suppressed (BLIS), and mesenchymal-like (MES). Here, we aimed to evaluate the efficacy and safety of subtyping-based therapy in the first-line treatment of triple-negative breast cancer.
