Stilbenoid derivatives as potent inhibitors of HIF-1α-centric cancer metabolism under hypoxia.

Hypoxia-inducible factor (HIF)-1α is a crucial transcription factor associated with cancer metabolism and is regarded as a potent anticancer therapeutic strategy within the hypoxic microenvironment of cancer. In this study, stilbenoid derivatives were designed, synthesized, and assessed for their capacity to inhibit HIF-1α-associated cancer metabolism and evaluated for inhibition of cancer cell viability and HIF activation. Through the structure-activity relationship studies, compound 28e was identified as the most potent derivative.

Single-cell RNA sequencing reveals the process of CA19-9 production and dynamics of the immune microenvironment between CA19-9 (+) and CA19-9 (-) PDAC.

Background: Pancreatic ductal adenocarcinoma (PDAC) is one of the main types of malignant tumor of the digestive system, and patient prognosis is affected by difficulties in early diagnosis, poor treatment response, and a high postoperative recurrence rate. Carbohydrate antigen 19-9 (CA19-9) has been widely used as a biomarker for the diagnosis and postoperative follow-up of PDAC patients. Nevertheless, the production mechanism and potential role of CA19-9 in PDAC progression have not yet been elucidated.

Tailoring the taste of cultured meat.

A new protocol can customize the flavor of lab-grown meat by controlling the level of fat deposited between muscle cells.

Limitations and Innovative Application Methods of Surfactants for Solubilization of Poorly Water-Soluble Drugs.

Poor solubility of drugs leads to poor bioavailability and therapeutic efficiency. A large proportion of drugs that are not developed and marketed for use by patients are due to their extremely low solubility. Therefore, improving the solubility of poorly water-soluble drugs is one of the most important aspects of the field of drug research.

Effect of high-dose intravenous iron injection on hepatic function in a rat model of cirrhosis.

Objective: To investigate the hepatic effects of high-dose intravenous (IV) iron, including those on liver function and the degree of fibrosis, in a rat model of cirrhosis.

Methods: We evenly allocated 25 Sprague-Dawley rats into five groups: normal rats (control group), cirrhotic rats receiving IV normal saline (liver cirrhosis [LC] group), and cirrhotic rats receiving 20, 40, or 80 mg/kg IV ferric carboxymaltose (LC-iron20, LC-iron40, and LC-iron80 group, respectively). Biochemical parameters were compared at 0, 7, 14, 21, and 28 days.

Comparative study of optical fiber immunosensors based on traditional antibody or nanobody for detecting HER2.

In this study, we present a novel biomarker detection platform employing a modified S-tapered fiber coated with gold nanoparticle/graphene oxide (GNP/GO) for quantifying human epidermal growth factor receptor-2 (HER2) concentrations, using antibodies as sensing elements. The fabrication of this device involves implementing an in-situ layer-by-layer technique coupled with a chemical adsorption step to achieve the self-assembly of GNP, GO, and antibodies on the STF surface. The detection mechanism relies on monitoring the refractive index changes induced by the adsorption of HER2 onto the immobilized antibodies.

Association Between Preoperative Ocular Parameters and Myopic Shift in Children Undergoing Primary Intraocular Lens Implantation.

Purpose: To evaluate the association between preoperative ocular parameters and myopic shift following primary intraocular lens (IOL) implantation in pediatric cataracts.

Methods: Eyes from pediatric patients undergoing bilateral cataract surgery with primary IOL implantation were included. Eyes were grouped by age at surgery and subdivided into three axial length (AL) subgroups and three keratometry subgroups.

Synchronous liver metastasis at initial diagnosis of adrenal pheochromocytoma by CT: A case report.

Pheochromocytoma is a tumor of the sympathetic nervous system, characterized by atypical symptoms and signs. Pheochromocytoma metastases can be found in various tissues and organs. However, synchronous metastasis at the initial diagnosis of pheochromocytoma is rare.

A prospective randomized controlled clinical trial investigating the efficacy of low-dose olanzapine in preventing nausea and vomiting associated with oxaliplatin-based and irinotecan-based chemotherapy.

Objective: The aim of this study is to assess the clinical efficacy of a 5 mg dosage of olanzapine in preventing chemotherapy-induced nausea and vomiting (CINV) associated with moderately emetogenic chemotherapy (MEC) among female patients diagnosed with gastrointestinal tract tumors.

Methods: Patients undergoing the oxaliplatin/irinotecan chemotherapy regimen were enrolled in this prospective controlled study. The olanzapine group received a 5 mg dosage of olanzapine along with palonosetron and dexamethasone, while the control group received a standard two-combination regimen consisting of dexamethasone and palonosetron.

A single infusion of engineered long-lived and multifunctional T cells confers durable remission of asthma in mice.

Asthma, the most prevalent respiratory disease, affects more than 300 million people and causes more than 250,000 deaths annually. Type 2-high asthma is characterized by interleukin (IL)-5-driven eosinophilia, along with airway inflammation and remodeling caused by IL-4 and IL-13. Here we utilize IL-5 as the targeting domain and deplete BCOR and ZC3H12A to engineer long-lived chimeric antigen receptor (CAR) T cells that can eradicate eosinophils.

Multiomic analyses reveal key sectors of jasmonate-mediated defense responses in rice.

The phytohormone jasmonate (JA) plays a central role in plant defenses against biotic stressors. However, our knowledge of the JA signaling pathway in rice (Oryza sativa) remains incomplete. Here, we integrated multiomic data from three tissues to characterize the functional modules involved in organizing JA-responsive genes.

An Early Cost-Utility Model of mRNA-Based Therapies for the Treatment of Methylmalonic and Propionic Acidemia in the United Kingdom.

Background And Objective: Novel messenger RNA (mRNA)-based therapies, currently in development, are emerging as a promising potential treatment modality for a broad range of life-threatening and life-limiting inherited liver diseases, including methylmalonic acidemia (MMA) and propionic acidemia (PA). However, owing in part to their complexity, they are likely to come at considerable financial cost to healthcare systems. The objective of this research was to synthesize available evidence on the costs and clinical consequences associated with MMA and PA for the purpose of exploratory economic evaluation of novel mRNA-based therapies using an early cost-utility model from the United Kingdom payer perspective.

Apolipoprotein D3 and LOX product play a role in immune-priming of a lepidopteran insect, Spodoptera exigua.

BranchLabelNet: Anatomical Human Airway Labeling Approach using a Dividing-and-Grouping Multi-Label Classification.

Anatomical airway labeling is crucial for precisely identifying airways displaying symptoms such as constriction, increased wall thickness, and modified branching patterns, facilitating the diagnosis and treatment of pulmonary ailments. This study introduces an innovative airway labeling methodology, BranchLabelNet, which accounts for the fractal nature of airways and inherent hierarchical branch nomenclature. In developing this methodology, branch-related parameters, including position vectors, generation levels, branch lengths, areas, perimeters, and more, are extracted from a dataset of 1000 chest computed tomography (CT) images.

Autosomal Dominant Weill-Marchesani-Like Syndrome in a Chinese Family due to Novel Haplotypic Mutations in LTBP2.

Introduction: Weill-Marchesani syndrome (WMS) is a hereditary connective tissue disorder with substantial heterogeneity in clinical features and genetic etiology, so it is essential to define the full mutation spectrum for earlier diagnosis. In this study, we report Weill-Marchesani-like syndrome (WMS-like) change to autosomal dominance inheritance caused by novel haplotypic mutations in latent transforming growth factor beta-binding protein 2 (LTBP2).

Methods: Twenty-five members from a 4-generation Chinese family were recruited from Guangzhou, of whom nine were diagnosed with WMS-like disease, nine were healthy, and seven were of "uncertain" clinical status because of their young age.

Association of serum metal levels with type 2 diabetes: A prospective cohort and mediating effects of metabolites analysis in Chinese population.
