Buparlisib and Paclitaxel in Patients with Head and Neck Squamous Cell Carcinoma: Immunogenomic Biomarkers of Efficacy from the BERIL-1 Study.

Background: BERIL-1 was a randomized phase 2 study that studied paclitaxel with either buparlisib, a pan-class I PIK3 inhibitor, or placebo in patients with recurrent or metastatic (R/M) head and neck squamous cell cancer (HNSCC). Considering the therapeutic paradigm shift with immune checkpoint inhibitors (ICIs) now approved in the first-line setting, we present an updated immunogenomic analysis of patients enrolled in BERIL-1, including patients with immune-infiltrated tumors.

Objective: The objective of this study was to identify biomarkers predictive of treatment efficacy in the context of the post-ICI therapeutic landscape.

Microstructure and Mechanical Properties of Rolled (TiC + Ti1400)/TC4 Composites.

One of the long-standing challenges in the field of titanium matrix composites is achieving the synergistic optimization of high strength and excellent ductility. When pursuing high strength characteristics in materials, it is often difficult to consider their ductility. Therefore, this study prepared a Ti1400 alloy and in situ synthesized TiC-reinforced (TiC + Ti1400)/TC4 composites using low-energy ball milling and spark plasma sintering technology, followed by hot rolling, to obtain titanium matrix composites with excellent mechanical properties.

Genome-Wide Identification and Expression Analysis of Amino Acid/Auxin Permease (AAAP) Genes in Grapes ( L.) Under Abiotic Stress and During Development.

Amino acids in wine grapes function as precursors for various secondary metabolites and play a vital role in plant growth, development, and stress resistance. The amino acid/auxin permease () genes encode a large family of transporters; however, the identification and function of the gene family in grapes remain limited. Consequently, we conducted a comprehensive bioinformatics analysis of all genes in grapes, encompassing genome sequence analysis, conserved protein domain identification, chromosomal localization, phylogenetic relationship analysis, and gene expression profiling.

Spatial transcriptomic characterization of a Carnegie stage 7 human embryo.

Gastrulation marks a pivotal stage in mammalian embryonic development, establishing the three germ layers and body axis through lineage diversification and morphogenetic movements. However, studying human gastrulating embryos is challenging due to limited access to early tissues. Here we show the use of spatial transcriptomics to analyse a fully intact Carnegie stage 7 human embryo at single-cell resolution, along with immunofluorescence validations in a second embryo.

Oral colon-targeted responsive chitosan/pectin-based nanoparticles propels the application of tofacitinib in colitis therapy.

Tofacitinib (Tof), a commercially available pan-Janus kinases inhibitor, is approved for the treatment of moderate to severe ulcerative colitis.

The significant role of vegetation activity in regulating wetland methane emission in China.

Accurate quantifying of methane (CH) emissions is a critical aspect of current research on regional carbon budgets. However, due to limitations in observational data, research methodologies, and an incomplete understanding of process mechanisms, significant uncertainties persist in the assessment of wetland CH fluxes in China. In this study, we developed a machine learning model by integrating measured CH fluxes with related environmental data to produce a high-resolution (1 km) dataset of CH fluxes from China's wetlands for the period 2000-2020.

A carboxymethyl cellulose-based pH-responsive chlorine dioxide release film for strawberry preservation.

Fruit spoilage caused by microorganisms results in huge economic losses and health risks worldwide every year. To develop an intelligent antimicrobial material capable of responding to the physiological activity of postharvest fruits and releasing antibacterial agents on demand, we fabricated a pH-responsive film for the release of chlorine dioxide (ClO) using carboxymethyl cellulose (CMC) and sodium chlorite (NaClO) via the solution casting method, with a CMC:NaClO ratio of 1:2 w/w. An acid environment simulated by 4 % acetic acid activated 43 % of ClO released by the film within 7 days.

Gastrodin protects against sepsis-associated encephalopathy by suppressing ferroptosis.

Background: Sepsis-associated encephalopathy (SAE) represents a severe complication of sepsis, substantially elevating both mortality and healthcare costs for patients. Gastrodin (GAS), a principal bioactive constituent of Gastrodia elata Blume, is neuroprotective in various neurological disorders, including ischemic stroke, epilepsy, Alzheimer's disease, and neuropathic pain. In this study, we sought to investigate whether GAS could serve as a protective agent against SAE.

LGR4 promotes proliferation and homing via activation of the NF‑κB signaling pathway in multiple myeloma.

Multiple myeloma (MM) is a plasma cell malignancy characterized by clonal proliferation in the bone marrow (BM). Previously, it was reported that G‑protein‑coupled receptor 4 (LGR4) contributed to early hematopoiesis and was associated with poor prognosis in patients with MM. However, the mechanism of cell homing and migration, which is critical for MM progression, remains unclear.

IRGM Deficiency Exacerbates Sepsis-Induced Acute Lung Injury by Inhibiting Autophagy Through the AKT/mTOR Signaling Pathway.

Background: Sepsis is a life-threatening condition characterized by organ dysfunction due to an impaired immune response to infection. The lungs are highly susceptible to infection, often resulting in acute lung injury (ALI). The immune-related GTPase M (IRGM) and its murine homolog Irgm1 mediate autophagy and are implicated in inflammatory diseases, yet their roles in sepsis-induced ALI remain unclear.
