Article Synopsis
  • - The study develops a multi-view learning (MVL) model to better predict the prognosis of diffuse large B-cell lymphoma (DLBCL) patients by leveraging both clinical and imaging data, as current PET/CT imaging practices often overlook prognostic factors.
  • - The methodology includes advanced techniques like feature extraction, recursive feature elimination, and kernel canonical correlation analysis (KCCA) to enhance data analysis, ultimately training a support vector machine (SVM) model named SVM-2view-KCCA (SVM-2 K).
  • - Results show that the SVM-2 K model significantly outperformed existing models, achieving notable improvements in various performance metrics such as AUC (10.5% increase) and sensitivity (11

Storage time is considered to be one of the most important factors affecting the obnoxious odor and microbial spoilage of fresh meat. In this study, volatile organic compounds (VOCs) and bacterial community structure of chilled goose meat during storage were investigated. The results showed that numerous VOCs were produced during the fresh goose meat storage, including aldehydes (nonanal, (E)-2-octenal, hexanal, tetradecanal), alcohol (1-octen-3-ol), furan (2-pentylfuran), and carboxylic acids (methyl diethyldithiocarbamate), which might be a breakdown product during spoilage.

The study aimed to determine the specific relative biological effectiveness (RBE) of various cells in the hippocampus following proton irradiation. Sixty Sprague-Dawley rats were randomly allocated to 5 groups receiving 20 or 30 Gy of proton or photon irradiation.

Background: Ibrutinib and zanubrutinib are Bruton tyrosine kinase inhibitors used to treat mantle cell lymphoma, chronic lymphocytic leukemia, and small lymphocytic lymphoma. Dihydroxydiol ibrutinib (DHI) is an active metabolite of the drug. A liquid chromatography-tandem mass spectrometry method was developed to detect ibrutinib, DHI, and zanubrutinib in human plasma.

Hutchinson-Gilford progeria syndrome (HGPS) is an extremely rare disease characterized by appearance of premature aging, including the skin, bones, heart, and blood vessels caused by LMNA mutation. In this study, the patient presented with congenital micrognathia and progressively aggravated upper airway obstruction as the initial symptom, which required bilateral mandibular distraction osteogenesis (MDO) surgery intervention. This was not commonly described in the literature, and the primary clinical diagnosis of Pierre Robin sequence (PRS) was made.

The programmed death protein 1/programmed cell death ligand 1 (PD-1/PD-L1) pathway plays a significant role in immune evasion. PD-1 or PD-L1 immune checkpoint inhibitors (ICIs) have become a standard treatment for multiple types of cancer. To date, PD-L1 has served as a biomarker for predicting the efficacy of ICIs in several cancers.

Article Synopsis
  • Ibrutinib, orelabrutinib, and zanubrutinib are Bruton's tyrosine kinase inhibitors that have significantly advanced the treatment of B-cell malignancies.
  • A validated LC-MS/MS method was developed to measure the plasma concentrations of these drugs and their metabolites in patients, using Ibrutinib-d5 as an internal standard.
  • The analytical method demonstrated strong performance, with acceptable levels of selectivity, precision, and stability, allowing for accurate quantification of the drugs in clinical settings.

Cycloaddition reactions are among the most widely used reactions in chemical synthesis. Nature achieves these cyclization reactions with a variety of enzymes, including Diels-Alderases that catalyse concerted 4 + 2 cycloadditions, but biosynthetic enzymes with 2 + 2 cyclase activity have yet to be discovered. Here we report that PloI4, a β-barrel-fold protein homologous to the exo-selective 4 + 2 cyclase that functions in the biosynthesis of pyrroindomycins, catalyses competitive 2 + 2 and 4 + 2 cycloaddition reactions.

  • Chickens can maintain good health even with high blood glucose levels, but the specific biomolecules involved in this process are still unknown.
  • Research on chicken serum metabolites showed that treatment reduced blood glucose levels and harmful compounds in rats with Type 2 Diabetes Mellitus (T2DM).
  • DL-arginine emerged as a key metabolite, effectively lowering blood glucose and inflammation markers in these rats, indicating its potential as a treatment for managing hyperglycemia.

  • Melanotic neuro-ectodermal tumor of infancy (MNTI) is a rare tumor that typically occurs in infants under 6 months old, characterized by a rapidly-growing, non-ulcerated soft tissue swelling with pigmented mucosa.
  • A study of four patients revealed distinctive imaging features using ultrasound, CT, and MRI, including osteolytic maxillary bone destruction and specific signal intensities on MRI scans.
  • Recognizing the imaging characteristics along with clinical history is essential for diagnosing MNTI, as there are no signs of metastasis in affected patients.

Cell adhesion and differentiation can be regulated through material engineering, but current methods have low temporal and spatial accuracy to control . Here, we developed an up-conversion nanoparticle (UCNP) substrate to regulate cell adhesion and multidifferentiation in mesenchymal stem cells (MSCs) by near-infrared (NIR) light. First, the cell-adhesive peptide Arg-Gly-Asp (RGD) was conjugated on the surface of UCNPs, and the photocleavage 4-(hydroxymethyl)-3-nitrobenzoic acid (ONA) was connected to RGD.

CPT1C, which is expressed in hippocampus, influences ceramide level, endogenous cannabinoid and oxidation process, as well as plays an important role in various brain functions such as learning. This study aimed to investigate the role of CPT1C in Alzheimer's disease (AD) and its underlying mechanism. We established a model of Alzheimer's disease in vitro by exposing primary hippocampal neurons to beta-Amyloid peptide fragment 25-35 (Aβ).

During the early stages of the pandemic, some coronavirus disease (COVID-19) patients were misdiagnosed as having influenza, which aroused the concern that some deaths attributed to influenza were actually COVID-19-related. However, little is known about whether coinfection with influenza contributes to severity of COVID-19 pneumonia, and the optimal therapeutic strategy for these patients. We retrospectively studied 128 hospitalized patients with COVID-19 pneumonia.

  • Myosin VI is essential for various cellular processes, especially in autophagy, where it helps autophagosomes mature by interacting with specific proteins like Tom1 and autophagy receptors (Optineurin, NDP52, TAX1BP1).
  • The study reveals the high-resolution crystal structure of Myosin VI's C-terminal cargo-binding domain (CBD) in complex with Tom1, detailing how Myosin VI specifically interacts with Tom1 through a unique cargo recognition mechanism.
  • Additionally, Myosin VI acts as a bridging adaptor, connecting Tom1 and autophagy receptors through two distinct interaction sites, offering deeper insights into their roles in autophagy.

Article Synopsis
  • Cisplatin is an effective chemotherapy drug for treating cancer but can cause kidney damage (nephrotoxicity), limiting its use.
  • This study investigates the protective effects of Huaiqihuang (HQH), a Chinese herbal complex, against cisplatin-induced kidney damage in mice, finding that HQH significantly reduces kidney injury markers and cell apoptosis.
  • HQH works similarly to the steroid dexamethasone in protecting kidney function, suggesting it could be a safer alternative adjunct treatment alongside cisplatin for cancer patients.
