A multicenter, randomized, double-blind, placebo-controlled phase 3 study of Socazolimab or placebo combined with carboplatin and etoposide in the first-line treatment of extensive-stage small cell lung cancer.

This is a randomized, double-blind, placebo-controlled phase 3 clinical trial (ClinicalTrials.gov, NCT04878016) conducted in 54 hospitals in China. Adults who were histologically diagnosed and never treated for extensive-stage small cell lung cancer (ES-SCLC) were enrolled.

Effect of Compound Danshen Dripping Pills on cardiac function after acute anterior ST-segment elevation myocardial infarction: A randomized trial.

The current study aimed to evaluate the efficacy and safety of Compound Danshen Dripping Pills (CDDP) in improving cardiac function among patients with acute anterior ST-segment elevation myocardial infarction (AAMI). Between February 2021 and February 2023, 247 eligible patients with AAMI after primary percutaneous coronary intervention (pPCI) were enrolled and randomly assigned (1∶1) to receive CDDP ( = 126) or placebo ( = 121), with a follow-up of 48 weeks. Compared with the placebo group, the CDDP group demonstrated a significant increase in left ventricular ejection fraction (LVEF) values after 24 weeks of the treatment (least squares mean: 3.

Calcium-magnesium synergy in reducing cadmium bioavailability and uptake in rice plants.

The synergistic application of calcium (Ca) and magnesium (Mg) was investigated to mitigate cadmium (Cd) uptake and translocation in rice grown in Cd-contaminated soil. A pot experiment was conducted using different Ca:Mg molar ratios (Ca1:Mg2, Ca2:Mg1, and Ca1:Mg1) to evaluate their effect on Cd uptake. The results showed that the Ca1:Mg1 treatment achieved the highest reduction in grain Cd content (54.

AYVM to AYMM transition on HER2 exon 20 insertion induces TKI resistance in NSCLC.

Pyrotinib, a novel pan-HER tyrosine kinase inhibitor, has demonstrated substantial anti-tumor activity in non-small cell lung cancer (NSCLC) patients harboring HER2 mutations. However, the inevitable resistance to pyrotinib necessitates an in-depth understanding of the underlying mechanisms. In this study, potential resistance-associated mutations were identified through genomic sequencing of clinically paired samples and were validated using in vitro and in vivo models.

The Combination of Aligned PDA-Fe@PLCL Conduit with Aligned GelMA Hydrogel Promotes Peripheral Nerve Regeneration.

Biomaterial-assisted therapeutic strategies enable precise modulation to direct endogenous cellular responses and harness regenerative capabilities for nerve repair. However, achieving effective cellular engagement during nerve remodeling remains challenging. Herein, a novel composite nerve guidance conduit (NGC), the GelMA/PLys@PDA-Fe@PLCL conduit is developed by combining aligned poly(l-lactide-co-caprolactone) (PLCL) nanofibers modified with polydopamine (PDA), ferrous iron (Fe⁺), and polylysine (PLys) with aligned methacrylate-anhydride gelatin (GelMA) hydrogel nanofibers.

Dramatic Response to Ensartinib in Metastatic Neuroendocrine Tumors With a Novel CEP44-ALK Fusion: A Case Report and Literature Review.

Neuroendocrine tumor (NET) is a deadly malignancy disease that can be found anywhere in the body. The lack of tumor-specific treatment led to the worse prognosis of NET. Anaplastic lymphoma kinase-tyrosine kinase inhibitors (ALK-TKIs), such as alectinib and crizotinib, have been used in the treatment of NET patients with ALK rearrangement.

OsbHLH5 Synergically Regulates Phenolamide and Diterpenoid Phytoalexins Involved in the Defense of Rice Against Pathogens.

Rice () produces phenolamides and diterpenoids as major phytoalexins. Although the biosynthetic pathways of phenolamides and diterpenoids in plants have been revealed, knowledge of their accumulation regulatory mechanisms remains limited, and, in particular, no co-regulatory factor has been identified to date. Here, using a combined co-expression and evolutionary analysis, we identified the basic helix-loop-helix (bHLH) transcription factor as a positive bifunctional regulator of phenolamide and diterpenoid biosynthesis in rice.

Non-Interleaved Shared-Aperture Full-Stokes Metalens via Prior-Knowledge-Driven Inverse Design.

Characterization of electromagnetic wave polarization states is critical in various applications of materials, biomedical, and imaging. The emergence of metasurfaces opens up the possibility of implementing highly integrated full-Stokes imagers. Despite rapid development, prevailing schemes on metasurface-based full-Stokes imagers require interleaved or cascaded designs, inevitably resulting in performance deterioration, bulky size, and complicating the imaging procedure due to misalignment.

Case report: targeted therapy of malignant pleural mesothelioma with anaplastic lymphoma kinase receptor tyrosine kinase gene fusion mutation by crizotinib.

Malignant mesothelioma is a rare highly invasive tumour originating from the mesothelial cells of the pleura, peritoneum and pericardium. Malignant pleural mesothelioma (MPM) is the most common type in all malignant mesothelioma. The onset of MPM is associated with exposure to asbestos and it can have an incubation period of up to 40 years.

Durvalumab Versus Chemotherapy as First-line Treatment for Metastatic NSCLC With Tumor PD-L1 Expression of 25% or Higher: Results From the Randomized Phase 3 PEARL Study.

Introduction: PEARL (NCT03003962) is an open-label, phase 3 study comparing first-line durvalumab monotherapy with chemotherapy in patients with metastatic NSCLC (mNSCLC [EGFR/ALK wild type]) with programmed cell death ligand 1 (PD-L1) tumor cell (TC) membrane expression status of 25% or higher. We report the final analysis of PEARL.

Methods: Adults (N = 669) with previously untreated stage IV mNSCLC were randomized (1:1) to durvalumab 20 mg/kg every four weeks or chemotherapy every three weeks for four to six cycles.

Brief Report: Ivonescimab Combined With Etoposide Plus Carboplatin as First-Line Treatment for Extensive-Stage SCLC: Results of a Phase 1b Clinical Trial.

Introduction: Ivonescimab is a humanized IgG1 bispecific anti-programmed cell death protein 1/vascular endothelial growth factor antibody. This study aimed to evaluate the safety and tolerance of ivonescimab combined with etoposide and carboplatin as first-line treatment in patients with extensive-stage SCLC and to explore the primary efficacy of this regimen.

Methods: Eligible patients received intravenous ivonescimab 3 mg/kg, 10 mg/kg, or 20 mg/kg every 3 weeks combined with etoposide and carboplatin for up to four cycles, followed by ivonescimab as maintenance.

Malassezia gallinae sp. nov., a new basidiomycetous yeast species isolated from skins of chickens.

Species of Malassezia are lipid-dependent yeasts and integral components of the skin microbiome. Most of the currently known species are isolated from mammals. However, the presence and distribution of Malassezia yeasts on the skin of avian species have not been fully understood or elucidated.

CHK1 attenuates cardiac dysfunction via suppressing SIRT1-ubiquitination.

Background: Mitochondrial dysfunction is linked to myocardial ischemia-reperfusion (I/R) injury. Checkpoint kinase 1 (CHK1) could facilitate cardiomyocyte proliferation, however, its role on mitochondrial function in I/R injury remains unknown.

Methods: To investigate the role of CHK1 on mitochondrial function following I/R injury, cardiomyocyte-specific knockout/overexpression mouse models were generated.

Oleogels loaded with lycopene structured using Zein/EGCG/Ca complexes: Preparation, characterization and potential application.

Oleogels have attracted considerable attention due to their excellent viscoelasticity and high content of polyunsaturated fatty acid. This study explored the potential of Zein/(-)-epigallocatechin-3-gallate/Ca complexes oleogels loaded with lycopene as potential substitute for solid fats in biscuit formulations. Utilizing an emulsion-templated method, oleogels were prepared and characterized for visual appearance, droplet size, microstructure, and rheological properties.
