Small cell lung cancer (SCLC) is a highly aggressive malignancy that lacks effective targeted therapies, in part due to frequent loss-of-function mutations in tumor suppressors and the absence of recurrent oncogenic drivers. Approximately 15% of SCLCs harbor inactivating mutations in NOTCH1 or NOTCH2, and most neuroendocrine-high SCLCs exhibit low NOTCH activity. Using CRISPR-Cas9 screening in primary cell lines derived from NOTCH1/2-isogenic SCLC genetically engineered mouse models, we identified TRIM28 as a synthetic lethal dependency in NOTCH2-inactivated SCLCs.

Background: The optimal cannulation strategy for acute type A aortic dissection (ATAAD) surgery via a minimally invasive approach remains a topic of debate. This study aimed to compare the feasibility and safety of different aortic arch branch cannulation techniques using a single upper hemisternotomy.
Methods: A retrospective analysis was performed on 207 patients with ATAAD who underwent total arch replacement combined with frozen elephant trunk techniques between December 2019 and July 2023.
Dynamic changes in moisture and volatile organic compounds (VOCs) of green pepper (GP) during hot-air drying (HAD), far-infrared drying (FIRD), and freeze drying (FD) were investigated. Results showed HAD increased terpenoids peak area by 44.72 %, the drying time of FIRD was only 5 h, and the FD piperine retention was 135 %.

In the multifactorial etiology of DED, oxidative stress is at the core, initiating a sequence of inflammatory responses and surface damage via a vicious cycle. However, current therapies merely have a narrow focus on inflammation.

Baicalein, a flavonoid from Scutellaria baicalensis, exhibits anti-inflammatory and immunomodulatory properties. This study evaluates baicalein's therapeutic potential in mitigating URSA via the TLR4/NF-κB signaling pathway.

Ulcerative colitis (UC) is non-specific inflammatory bowel disease. UC development and progression were closely associated with epigenetic modifications. Nevertheless, the specific relationship between N6-methyladenosine (m6A) modification at RNA transcription levels and UC pathogenesis remains unclear.

Background: Mycoplasma pneumoniae (MP) is a major cause of community-acquired pneumonia (CAP), posing diagnostic challenges. This study evaluates novel inflammatory biomarkers, including neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII) and system inflammation response index (SIRI) for MP diagnosis in children.
Methods: Complete blood count (CBC) results of 424 children with MP infection and 150 health children were collected.
Exploring feasible drugs for the treatment of pathological cardiac hypertrophy has always been a focus of cardiovascular disease research. Paeoniflorin (PF) and β-Ecdysterone (β-Ecd) are the main active components of Paeonia lactiflora and Achyranthes bidentata, which can be used for the treatment of cardiovascular diseases, but their mechanism of action remains unclear. This study focused on oxidative stress and ferroptosis to investigate the protective effects of PF and β-Ecd on cardiac hypertrophy in primary cardiomyocytes and C57BL/6 mice, utilizing the integration of CCK8 assays, ROS detection, molecular docking, real-time quantitative PCR, western blot, immunofluorescence, etc.

However, the obscurity of the chemicals and the molecular mechanisms are impediments to their continued growth and globalization. Therefore, new modern medications based on the combination of beneficial TCM components with precise clinical efficacy are required.

During tissue regeneration, adult stem cells coordinately repress retrotransposons and activate lineage genes, but how this coordination is controlled is poorly understood. Here, we observed that dynamic expression of histone methyltransferase SETDB1 (a retrotransposon repressor) closely mirrors stem cell activities in murine skin.

Plasma proteins are considered the most informative source of biomarkers for disease diagnosis and monitoring. Mass spectrometry (MS)-based proteomics has been applied to identify biomarkers in plasma, but the complexity of the plasma proteome and the extremely large dynamic range of protein abundances in plasma make the clinical application of plasma proteomics highly challenging. We designed and synthesized zeolite-based nanoparticles to deplete high-abundance plasma proteins.

Currently, there is a growing interest in using whole grain (WG)-specific phytochemicals to perform WG research, including research on dietary assessment, health mechanisms, and quality control. However, the current approaches used for WG-specific phytochemical analysis cannot simultaneously achieve coverage, specificity, and sensitivity. In the present study, a series of WG-specific phytochemicals (alkylresorcinols (ARs), benzoxazinoids (BXs) and avenanthramides (AVAs)) were identified, and their mass spectrometry (MS) fragmentation mechanism was studied by TOF MS.
