Glycosylation is central to the localization and function of biomolecules. We recently discovered that small RNAs undergo N-glycosylation at the modified RNA base 3-(3-amino-3-carboxypropyl) uridine (acpU). However, the functional significance of N-glycosylation of RNAs is unknown.

Methods: Plasma metabolites were measured using untargeted UPLC-MS/MS (n = 94 and 40), with lymphocyte subset tests on 72 patients. BCAA-related subtypes were identified in NSCLC datasets (n = 274, 176, and 196).
Glioblastoma (GB) is a highly aggressive brain tumor resistant to chemoradiotherapy, largely due to glioma stem-like cells (GSCs) with robust DNA damage repair capabilities. Here we reveal that GSCs enhance their DNA repair capacity by activating non-homologous end-joining (NHEJ) through upregulation of the apoptosis antagonizing transcription factor (AATF), thereby promoting therapeutic resistance in GB. AATF interacts with XRCC4, a core NHEJ subunit, preventing its degradation via ubiquitin-mediated proteasomal processes.

To solve the above problems, a two-stage detection method was developed for the automatic detection and identification of blood cells. First, for the blood cell detection task, an improved YOLOv7 blood cell detection model was proposed that integrates multihead attention and the SCYLLA-IoU (SIoU) loss function to accurately locate and classify white blood cells (WBCs), red blood cells (RBCs), and platelets in a full-field image of blood cells.

AML typing traditionally relies on manual microscopy for classifying and counting myeloid cells, which is time-consuming, laborious, and subjective. Therefore, developing a reliable automated model for myeloid cell classification is imperative.

Purpose: The diagnosis and treatment of B-Lineage Acute Lymphoblastic Leukemia (B-ALL) typically rely on cytomorphologic analysis of bone marrow smears. However, traditional morphological analysis methods require manual operation, leading to challenges such as high subjectivity and low efficiency. Accurate segmentation of individual cell nuclei is crucial for obtaining detailed morphological characterization data, thereby improving the objectivity and consistency of diagnoses.

Yeast, identified as a microorganism, boasts a considerable protein content, positioning yeast protein as a highly promising alternative in the quest for sustainable protein sources. The primary aim of this study is to evaluate the protein quality of yeast protein and compare it with animal proteins (whey concentrate/isolate proteins) and plant proteins (soy, wheat, pea proteins). Notably, yeast protein exhibits the highest ratio of indispensable/dispensable amino acids (IAAs/DAAs, 0.

In this study, we propose a model for predicting the dosage of anesthetic drugs based on deep learning to help anesthesiologists better control their dosage during surgical procedures.
Methods: We design a model based on the artificial neural network to predict the dosage of preoperative anesthetic, and use the SELU activation function and the loss function for weighted regularization to solve the problem of unbalanced sample.
Scope: To assess the associations of dietary protein intake from different sources during pregnancy with maternal and umbilical cord plasma amino acid levels.

Objective: This study aims to assess the effectiveness of traditional Chinese exercise therapy in alleviating pain, improving sleep quality, and reducing symptoms of anxiety and depression among fibromyalgia patients.
Methods: We conducted a comprehensive search across various databases, including PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge, VIP database, and Wanfang, to identify randomized controlled trials (RCTs) examining the impact of Traditional Chinese Exercise (TCE) interventions on fibromyalgia. Two independent authors extracted data from the selected studies based on predefined inclusion and exclusion criteria.
The metabolism of polycyclic aromatic hydrocarbons (PAHs) and the elimination kinetics of their mono-hydroxylated metabolites (OH-PAHs) following single exposure to different combinations of four PAHs (PAH4) were studied. Male Sprague-Dawley rats were orally exposed to a single dose of benzo[a]pyrene (B[a]P) or PAH2 (B[a]P + chrysene), PAH3 (B[a]P + chrysene + benz[a]anthracene), and PAH4 (B[a]P + chrysene + B[a]A + benzo[b]fluoranthene) with each combination adjusted to the same dose of individual compound. OH-PAHs including 3-hydroxybenzo[a]pyrene, 3-hydroxychrysene, 3-hydroxybenz[a]anthracene, and 1-hydroxypyrene (1-OHP) were detected in serum and urine samples collected at six intervals over a 72-h period post-dosing.

The communication between glioblastoma stem cells (GSCs) and the surrounding microenvironment is a prominent feature accounting for the aggressive biology of glioblastoma multiforme (GBM). However, the mechanisms by which GSCs proactively drive interactions with microenvironment is not well understood. In this study, we interrogated metabolites that are preferentially secreted from GSCs and found that GSCs produce and secrete histamine to shape a pro-angiogenic tumor microenvironment.
