Disruption of tumor-intrinsic PGAM5 increases anti-PD-1 efficacy through the CCL2 signaling pathway.

Background: Immunosuppressive phenotype compromised immunotherapy efficacy of hepatocellular carcinoma. Tumor cells intrinsic mitochondria dynamics could pass effects on the extracellular microenvironment through mtDNA stress. PGAM5 anchors at mitochondria and regulates mitochondria functions.

Fiber Vector Light-Field-Based Tip-Enhanced Raman Spectroscopy.

Tip-enhanced Raman spectroscopy (TERS) has been extensively employed to investigate the light-matter interaction at the nanoscale. However, the current TERS strategies lack the ability to excite the low-background inhomogeneous electromagnetic field with significant enhancement of electric field, electric field gradient, and optomagnetic field, simultaneously. To overcome this, we developed a fiber vector light-field-based TERS strategy aimed at exploring the multipole Raman scattering processes of molecules.

Surgery/non-surgery-based strategies for invasive locally-advanced non-small cell lung cancer in the era of precision medicine.

Background: Treatments for invasive T non-small cell lung cancer (NSCLC) tumors have been traditionally individualized and often require multidisciplinary team (MDT) evaluation. Advances in precision medicine may open up new opportunities for these patients.

Methods: This retrospective cohort study, using the Surveillance, Epidemiology, and End Results (SEER) database, identified TNM NSCLC patients with central structure invasion from 2010 to 2020.

Lipids-modified starch: Advances in structural characteristic, physicochemical property, and application.

Starch and lipids, as two important biomacromolecules in nature, can interact with each other to form a unique complex system during processing, leading to the change of the structural and functional characteristics of starch. The complex formed though the biomacromolecules interaction is a new kind of modified starch named as "lipid-modified starch". At present, the lipids-modified starch has attracted much researchers' attention and become a hotspot topic in food field.

Triggering immunogenic death of cancer cells by nanoparticles overcomes immunotherapy resistance.

Immunotherapy resistance poses a significant challenge in oncology, necessitating novel strategies to enhance the therapeutic efficacy. Immunogenic cell death (ICD), including necroptosis, pyroptosis and ferroptosis, triggers the release of tumor-associated antigens and numerous bioactive molecules. This release can potentiate a host immune response, thereby overcoming resistance to immunotherapy.

Effect and mechanism of different exogenous biomolecules on the thermal-induced gel properties of surimi: A review.

Surimi products are favored by domestic and foreign consumers due to their distinctive gelatinous texture, rich nutrition, and convenient consumption. Gel properties are key evaluation indicators for the quality of surimi products, which was mainly determined by the gel-forming ability of the myofibrillar protein (MP). In recent years, the surimi processing industry has faced challenges in product quality that limits the further development, and how to effectively improve the gel properties of surimi products has become one of the key scientific problems to be solved in surimi processing industry.

Construction and validation of a mouse model for studying severe human adenovirus infections.

Human adenoviruses (HAdVs) are highly contagious pathogens with various genotypes implicated in acute respiratory disease (ARD) and linked to fatality, especially in immunosuppressed patients, young children, and military recruits. Currently, no vaccines or specific drugs are approved for clinical use. The hosts of adenoviruses are strictly species-specific, which strongly limits the development of vaccines and drugs against HAdVs.

Engineering hirudin encapsulation in pH-responsive antioxidant nanoparticles for therapeutic efficacy in ischemic stroke model mice.

This study introduces a novel pH-sensitive, hirudin-loaded antioxidant nanoparticle (HD@iNano) aimed at addressing the challenges of hirudin's short half-life and hemorrhagic transformation. HD@iNano was engineered to safeguard and prolong hirudin's bioactivity by encapsulating it within antioxidative nanoparticles, facilitating its gradual release in acidic environments. The efficacy of this approach was validated through both ex vivo and in vivo experiments.

Multi-omics and artificial intelligence predict clinical outcomes of immunotherapy in non-small cell lung cancer patients.

In recent years, various types of immunotherapy, particularly the use of immune checkpoint inhibitors targeting programmed cell death 1 or programmed death ligand 1 (PD-L1), have revolutionized the management and prognosis of non-small cell lung cancer. PD-L1 is frequently used as a biomarker for predicting the likely benefit of immunotherapy for patients. However, some patients receiving immunotherapy have high response rates despite having low levels of PD-L1.

Outer membrane vesicles of avian pathogenic Escherichia coli induce necroptosis and NF-κB activation in chicken macrophages via RIPK1 mediation.

Outer membrane vesicles (OMVs) are soluble mediators secreted by Gram-negative bacteria that are involved in communication. They can carry a variety of harmful molecules, which induce cytotoxic responses and inflammatory reactions in the absence of direct host cell-bacterium interactions. We previously reported the isolation of OMVs from avian pathogenic Escherichia coli (APEC) culture medium by ultracentrifugation, and characterized them as a substance capable of inducing the production of pro-inflammatory cytokines and causing tissue damage.

Quantification of preexisting lung ground glass opacities on CT for predicting checkpoint inhibitor pneumonitis in advanced non-small cell lung cancer patients.

Background: Immune checkpoint inhibitors (ICIs) can lead to life-threatening pneumonitis, and pre-existing interstitial lung abnormalities (ILAs) are a risk factor for checkpoint inhibitor pneumonitis (CIP). However, the subjective assessment of ILA and the lack of standardized methods restrict its clinical utility as a predictive factor. This study aims to identify non-small cell lung cancer (NSCLC) patients at high risk of CIP using quantitative imaging.

First-line treatment of driver gene-negative metastatic lung adenocarcinoma with malignant pleural effusion: Should chemotherapy be combined with an immune checkpoint inhibitor or bevacizumab?

Patients with metastatic lung adenocarcinoma (MLA) and malignant pleural effusion (MPE) without driver gene mutations have a poor prognosis. None of the standard treatment strategies is recommended for such patients. We retrospectively analyzed the efficacy of the first-line treatment for this specific population: standard platinum-based doublet chemotherapy (CT), CT plus an immune checkpoint inhibitor (CT plus ICI), and CT plus bevacizumab (CT plus Bev).

Pathological complete response to neoadjuvant therapy with serplulimab and chemotherapy in stage IIIB small cell lung cancer: a case report and literature review.

Chemotherapy combined with immunotherapy has significantly improved survival in patients with extensive-stage small cell lung cancer (ES-SCLC), and neoadjuvant immunotherapy combined with chemotherapy has emerged as the standard treatment for those with resectable non-small cell lung cancer (NSCLC). However, the potential benefits of surgery following neoadjuvant immunotherapy combined with chemotherapy in locally advanced SCLC remain unclear. Herein, we report a patient diagnosed with stage IIIB SCLC, who was administered five cycles of neoadjuvant serplulimab combined with chemotherapy followed by surgery, and subsequently achieved a pathologic complete response (pCR).

Comprehensive analysis the prognostic and immune characteristics of mitochondrial transport-related gene SFXN1 in lung adenocarcinoma.

Background: Mitochondria, which serve as the fundamental organelle for cellular energy and metabolism, are closely linked to the growth and survival of cancer cells. This study aims to identify and assess Sideroflexin1 (SFXN1), an unprecedented mitochondrial gene, as a potential prognostic biomarker for lung adenocarcinoma (LUAD).

Methods: The mRNA and protein levels of SFXN1 were investigated based on the Cancer Genome Atlas (TCGA) LUAD dataset, and then validated by real-time quantitative PCR, Western Blotting and immunohistochemistry from our clinical samples.

Gray matter covariations in autism: out-of-sample replication using the ENIGMA autism cohort.

Background: Autism spectrum disorder (henceforth autism) is a complex neurodevelopmental condition associated with differences in gray matter (GM) volume covariations, as reported in our previous study of the Longitudinal European Autism Project (LEAP) data. To make progress on the identification of potential neural markers and to validate the robustness of our previous findings, we aimed to replicate our results using data from the Enhancing Neuroimaging Genetics Through Meta-Analysis (ENIGMA) autism working group.

Methods: We studied 781 autistic and 927 non-autistic individuals (6-30 years, IQ ≥ 50), across 37 sites.

Research on Hydrodynamic Characteristics of Electronic Paper Pixels Based on Electrowetting.

In this paper, we propose a driving waveform with a complex ramp pulse for an electrowetting display system. The relationship between the contact angle and viscosity of inks was calculated based on the fluid-motion characteristics of different viscosities. We obtained the suitable range of viscosity and voltage in the liquid-oil-solid three-phase contact display system.

Mechanisms of Serrated Flow and Microstructural Evolution in MarBN Steel.

The mechanisms of serrated flow and microstructural evolution in MarBN steel were studied under two strain rates (5 × 10 s and 5 × 10 s) at room temperature and high temperatures (430 °C and 630 °C). The experimental results show that the type-C serrations occurred at all temperatures under a high strain rate of 5 × 10 s. In contrast, type-B serrations occurred at 430 °C and 630 °C under a low strain rate of 5 × 10 s, indicating that the type of serrated flow was related to the strain rate.

The Low-Cycle Fatigue Behavior, Microstructure Evolution, and Life Prediction of SS304: Influence of Temperature.

To study the fatigue failure and microstructure evolution behavior of SS304, low-cycle fatigue tests are conducted at room temperature (RT), 300 °C, and 650 °C. The results indicate that, because of the influence of the dislocation walls, carbon-containing precipitates, and deformation twins, the cyclic hardening behavior is presented at RT. However, different from the cyclic hardening behavior at RT, the cyclic softening behavior of SS304 can be observed due to the dynamic recovery and recrystallization containing dislocation rearrangement and annihilation at 300 °C and 650 °C.

The quality and clinical translation of radiomics studies based on MRI for predicting Ki-67 levels in patients with breast cancer.

Objective: To evaluate the methodological quality of radiomics literature predicting Ki-67 levels based on MRI in patients with breast cancer (BC) and to propose suggestions for clinical translation.

Methods: In this review, we searched PubMed, Embase, and Web of Science for studies published on radiomics in patients with BC. We evaluated the methodological quality of the studies using the Radiomics Quality Score (RQS).

Isolation of novel simian adenoviruses from macaques for development of a vector for human gene therapy and vaccines.

Adenoviruses are widely used in gene therapy and vaccine delivery. Due to the high prevalence of human adenoviruses (HAdVs), the pre-existing immunity against HAdVs in humans is common, which limits the wide and repetitive use of HAdV vectors. In contrast, the pre-existing immunity against simian adenoviruses (SAdVs) is low in humans.

Clinico-pathological characteristics of IGFR1 and VEGF-A co-expression in early and locally advanced-stage lung adenocarcinoma.

Background: Although targeted therapies and immunotherapy have achieved significant clinical benefits in patients with certain pathological types of lung cancer. However, prognosis for patients with lung adenocarcinoma still remains unsatisfactory. It is of extremely importance to find ideal prognostic indicators to predict the prognosis of lung adenocarcinoma patients, especially for patients with early and locally advanced-stage lung adenocarcinoma.

Linking functional and structural brain organisation with behaviour in autism: a multimodal EU-AIMS Longitudinal European Autism Project (LEAP) study.

Neuroimaging analyses of brain structure and function in autism have typically been conducted in isolation, missing the sensitivity gains of linking data across modalities. Here we focus on the integration of structural and functional organisational properties of brain regions. We aim to identify novel brain-organisation phenotypes of autism.
