A core-satellite self-assembled SERS aptasensor used for ultrasensitive detection of AFB.

A surface-enhanced Raman scattering (SERS) aptasensor was developed using gold nanostars (Au NSs) and FeO@Au nanoparticles (NPs) for the highly sensitive detection of aflatoxin B (AFB). Au NSs were modified by the Raman reporter 4-aminothiophenol (PATP) and then coupled with cDNA to act as the capture probes (Au NSs@PATP-cDNA). FeO@Au NPs were modified with the AFB aptamer (AFB Apt) and used as signal probes (FeO@Au NPs-AFB Apt).

Lactate and lactylation in cancer.

Accumulated evidence has implicated the diverse and substantial influence of lactate on cellular differentiation and fate regulation in physiological and pathological settings, particularly in intricate conditions such as cancer. Specifically, lactate has been demonstrated to be pivotal in molding the tumor microenvironment (TME) through its effects on different cell populations. Within tumor cells, lactate impacts cell signaling pathways, augments the lactate shuttle process, boosts resistance to oxidative stress, and contributes to lactylation.

Ultra-processed foods consumption and risk of age-related eye diseases: a prospective cohort study with UK biobank.

Purpose: Consumption of ultra-processed foods (UPF) has been associated with increased risks of various age-related diseases. However, the potential association between UPF consumption and age-related eye diseases (AREDs) remains unclear. We aim to assess the associations between consumption of UPF and risk of AREDs including age-related macular degeneration (AMD), cataract and glaucoma.

Purpose: To investigate the correlation between apparent diffusion coefficient (ADC) histograms and high-risk clinicopathologic features related to uveal melanoma (UM) prognosis.

Methods: This retrospective study included 53 patients with UM who underwent diffusion-weighted imaging (DWI) between August 2015 and March 2024. Axial DWI was performed with a single-shot spin-echo echo-planar imaging sequence.

Novel insights into TCR-T cell therapy in solid neoplasms: optimizing adoptive immunotherapy.

Adoptive immunotherapy in the T cell landscape exhibits efficacy in cancer treatment. Over the past few decades, genetically modified T cells, particularly chimeric antigen receptor T cells, have enabled remarkable strides in the treatment of hematological malignancies. Besides, extensive exploration of multiple antigens for the treatment of solid tumors has led to clinical interest in the potential of T cells expressing the engineered T cell receptor (TCR).

NT5DC2 knockdown suppresses progression, glycolysis, and neuropathic pain in triple-negative breast cancer by blocking the EGFR pathway.

Triple-negative breast cancer (TNBC) is an exceptionally aggressive breast cancer subtype associated with neuropathic pain. This study explores the effects of 5'-nucleotidase domain-containing protein 2 (NT5DC2) on the progression of TNBC and neuropathic pain. Microarray analysis was conducted to identify differentially expressed genes in TNBC and the pathways involved.

The impact of wind energy on plant biomass production in China.

Global wind power expansion raises concerns about its potential impact on plant biomass production (PBP). Using a high-dimensional fixed effects model, this study reveals significant PBP reduction due to wind farm construction based on 2404 wind farms, 108,361 wind turbines, and 7,904,352 PBP observations during 2000-2022 in China. Within a 1-10 km buffer, the normalized differential vegetation and enhanced vegetation indices decrease from 0.

Amino acid metabolism reprogramming: shedding new light on T cell anti-tumor immunity.

Metabolic reprogramming of amino acids has been increasingly recognized to initiate and fuel tumorigenesis and survival. Therefore, there is emerging interest in the application of amino acid metabolic strategies in antitumor therapy. Tremendous efforts have been made to develop amino acid metabolic node interventions such as amino acid antagonists and targeting amino acid transporters, key enzymes of amino acid metabolism, and common downstream pathways of amino acid metabolism.

Adenomas of the ciliary body epithelium: clinics, histopathology and management.

Aims: Adenomas of the ciliary body epithelium, including adenoma of the pigmented ciliary body epithelium (APCE) and adenoma of the non-pigmented ciliary body epithelium (ANPCE), are extremely rare, and most knowledge about them comes from sporadic case reports. The purpose of this study was to provide a comprehensive understanding of adenomas of the ciliary body epithelium and to identify the similarities and differences between APCE and ANPCE.

Methods: This study was a retrospective case series comprising data from 41 patients obtained from retrieved publications and five cases diagnosed at the Shanghai Ninth People's Hospital.

Metformin and cancer hallmarks: shedding new lights on therapeutic repurposing.

Metformin is a well-known anti-diabetic drug that has been repurposed for several emerging applications, including as an anti-cancer agent. It boasts the distinct advantages of an excellent safety and tolerability profile and high cost-effectiveness at less than one US dollar per daily dose. Epidemiological evidence reveals that metformin reduces the risk of cancer and decreases cancer-related mortality in patients with diabetes; however, the exact mechanisms are not well understood.

Correlating somatic copy number alteration in aqueous humour cfDNA with chemotherapy history, eye salvage and pathological features in retinoblastoma.

Unlabelled: BackgroundThis study determined to probe the potential association between somatic copy number alteration (SCNA) in retinoblastoma (RB) aqueous humour (AH) and pathological high-risk factors, clinical features and previous chemotherapy history.

Methods: Single-centre retrospective cohort study from including 58 AH samples collected from 58 patients diagnosed. Among them, 41 samples were collected after enucleation and 17 samples were collected before intravitreal chemotherapy.

Novel insights into RB1 mutation.

Since the discovery of the retinoblastoma susceptibility gene (RB1) decades ago, RB1 has been regarded as a prototype tumor suppressor gene providing a paradigm for tumor genetic research. Constant research has updated the understanding of RB1-related pathways and their impact on tumor and nontumor diseases. Mutation of RB1 gene has been observed in multiple types of malignant tumors including prostate cancer, lung cancer, breast cancer, and almost every familial and sporadic case of retinoblastoma.

Myosin light chain kinase regulates intestinal permeability of mucosal homeostasis in Crohn's disease.

: Researchers have investigated the potential role of intestinal permeability in Crohn's disease pathogenesis. Intestinal permeability is usually mediated by cytoskeleton and intercellular junctions. The myosin light chain kinase (MLCK) is an enzyme that activates the myosin light chain to exert its function related to cytoskeleton contraction and tight junction regulation.

Construction of Hyaluronic Acid-Covered Hierarchically Porous MIL-nanoMOF for Loading and Controlled Release of Doxorubicin.

The porous nano-sized metal-organic framework (nanoMOF) and its proper surface modification could greatly promote the drug loading capability and introduce biocompatibility, biodegradability, and targeting functions into nano-drug delivery systems. Herein, the HACD@ADA-PA/MIL-101_NH (Fe)-P nanoparticle was successfully fabricated through supramolecular and coordination interactions from three building blocks, including hierarchically porous MIL-101_NH (Fe)-P nanoMOF, phosphite-modified adamantane (ADA-PA), and β-cyclodextrin (β-CD)-modified hyaluronic acid (HACD). The obtained HACD@ADA-PA/MIL-101_NH (Fe)-P nanoparticle was nano-sized and highly stable in physiological fluids.

Dissecting Target Toxic Tissue and Tissue Specific Responses of Irinotecan in Rats Using Metabolomics Approach.

As an anticancer agent, irinotecan (CPT-11) has been widely applied in clinical, especially in the treatment of colorectal cancer. However, its clinical use has long been limited by the side effects and potential tissue toxicity. To discriminate the target toxic tissues and dissect the specific response of target tissues after CPT-11 administration in rats, untargeted metabolomic study was conducted.
