Scaling Violation in Power Corrections to Energy Correlators from the Light-Ray Operator Product Expansion.

In recent years, energy correlators have emerged as a powerful tool to explore the field theoretic structure of strong interactions at particle colliders. In this Letter we initiate a novel study of the nonperturbative power corrections to the projected N-point energy correlators in the limit where the angle between the detectors is small. Using the light-ray operator product expansion as a guiding principle, we derive the power corrections in terms of two nonperturbative quantities describing the fragmentation of quarks and gluons.

Structural characterization revealed that GDPs-1 was mainly composed of glucose, galactose, and arabinose, with a molecular weight of 55.

Radiolabelled anti-PD-L1 peptide PET/CT in predicting the efficacy of neoadjuvant immunotherapy combined with chemotherapy in resectable non-small cell lung cancer.

Background: This study aimed to evaluate the predictive value of baseline PD-L1 targeted peptide Ga-NOTA-WL12 PET/CT in neoadjuvant immunotherapy combined with chemotherapy of resectable NSCLC.

Methods: Patients with resectable NSCLC (n = 20) enrolled in this prospective study received baseline paired Ga-NOTA-WL12 PET/CT and F-FDG PET/CT. After 2-4 cycles of toripalimab plus nab-paclitaxel and cisplatin, surgery was performed if R0 resection was available.

Fetal hepatocytes protect the HSPC genome via fetuin-A.

The maintenance of genomic integrity in rapidly proliferating cells is a substantial challenge during embryonic development. Although numerous cell-intrinsic mechanisms have been revealed, little is known about genome-protective effects and influences of developmental tissue microenvironments on tissue-forming cells. Here we show that fetal liver hepatocytes provide protection to haematopoietic stem and progenitor cell (HSPC) genomes.

Gene expression profiles of Chinese medaka (Oryzias sinensis) primary hepatocytes in response to estrone (E), 17β-estradiol (E) and estriol (E).

The natural estrogens, including estrone (E), 17β-estradiol (E), and estriol (E), are frequently detected in aquatic environment at relatively high levels. The most commonly used biomarkers for estrogens are mainly expressed in the liver of fish. Analyses of the global gene profiling in fish liver cells under estrogens treatment will provide precise toxicogenomic information of the natural estrogens which is still not well known.

Isolation, characterization, and activity of the polysaccharides in Bulbophyllum kwangtumgense Schltr.

A microwave-assisted method was used to extract the polysaccharide from Bulbophyllumkwangtumgense Schltr, and the optimum extraction conditions were determined by orthogonal experiments. The purified polysaccharide component BKP-1 had an obvious polysaccharide characteristic structure on the infrared spectrum and was mainly composed of xylose and glucuronic acid at a ratio of 0.568:0.

Radioiodinated Nanobody immunoPET probe for in vivo detection of CD147 in pan-cancer.

Background: To develop the extracellular matrix metalloproteinase inducer (CD147)-targeting therapeutic strategies, accurate detection of CD147 expression in tumors is crucial. Owing to their relatively low molecular weights and high affinities, nanobodies (Nbs) may be powerful candidates for cancer diagnosis and therapy. In this study, we developed a novel CD147-targeted nanobody radiotracer, [I]I-NB147, which provides guidance for the noninvasive detection of CD147-overexpressing cancers.

Holmium laser enucleation of the prostate: Modified urethral mucosa pre-dissected technique versus traditional three-lobe technique-A retrospective study.

Objective: The aim of this study is to investigate the effect of modified holmium laser enucleation of the prostrate (HoLEP) on the function of urine control.

Methods: An analysis was conducted on a cohort of 305 elderly patients in a retrospective study spanning from February 2019 to February 2023. The cohort consisted of 150 patients who underwent modified HoLEP and 155 patients who underwent traditional HoLEP.

Separation, purification, structure characterization, and immune activity of a polysaccharide from Alocasia cucullata obtained by freeze-thaw treatment.

In this study, ACP-1, a water-soluble polysaccharide was isolated from the roots of Alocasia cucullata (AC) using freeze-thaw treatment (FTT). Structural characterization revealed ACP-1 (2.10×10 Da) to be a homogeneous heteropolysaccharide primarily consisting of glucose, galactose, and arabinose, and a trace of fucose, rhamnose, and glucuronic acid.

Copper-64 Based PET-Radiopharmaceuticals: Ways to Clinical Translational.

Positron emission tomography (PET) as an advanced noninvasive imaging technique, provides unprecedented insights into the study of physiological and biochemical processes in vivo. Copper-64 (Cu) has a ideal half-life of 12.7 hours, with β+ and β-dual decay modes and abundant coordination chemistry, enabling the development of a wide variety of radiopharmaceuticals for PET imaging and radionuclide therapy.

Novel Peptide-Based Ga-Labeled Radiotracer for Preclinical Studies of TIM3 Expression.

T-cell immunoglobulin and mucin domain-3 (TIM3) is an immune checkpoint that plays a negative regulatory role in the immune response. TIM3-targeted drugs inhibit this negative regulation, thereby modulating the level of immune response activation. In the previous investigation, several peptides targeting TIM3 were identified through screening from a phage peptide library.

Spermidine mediates acetylhypusination of RIPK1 to suppress diabetes onset and progression.

It has been established that N-acetyltransferase (murine NAT1 (mNAT1) and human NAT2 (hNAT2)) mediates insulin sensitivity in type 2 diabetes. Here we show that mNAT1 deficiency leads to a decrease in cellular spermidine-a natural polyamine exhibiting health-protective and anti-ageing effects-but understanding of its mechanism is limited. We identify that mNAT1 and hNAT2 modulate a type of post-translational modification involving acetylated spermidine, which we name acetylhypusination, on receptor-interacting serine/threonine-protein kinase 1 (RIPK1)-a key regulator of inflammation and cell death.

Neutrophil pyroptosis regulates corneal wound healing and post-injury neovascularisation.

Rationale: The cornea is a unique structure that maintains its clarity by remaining avascular. Corneal injuries can lead to neovascularisation (CNV) and fibrosis and are the third most common cause of blindness worldwide.

Objective: Corneal injuries induce an immune cell infiltration to initiate reparative processes.

Next Generation of Solid Target Radionuclide Antibody Conjugates for Tumor Immuno-Therapy.

Immune checkpoint therapy has emerged as an effective treatment option for various types of cancers. Key immune checkpoint molecules, such as cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), programmed cell death protein 1 (PD-1), and lymphocyte activation gene 3 (LAG-3), have become pivotal targets in cancer immunotherapy. Antibodies designed to inhibit these molecules have demonstrated significant clinical efficacy.

Probabilistic health risk assessment of primary aromatic amines in polyamide cooking utensils in China by Monte Carlo simulation.

The migration of primary aromatic amines (PAAs) from food contact materials raises significant public health concerns. In this study, the migration levels of 26 PAAs were analyzed in 242 nylon cooking utensils using ultra-performance liquid chromatography-tandem mass spectrometry. A total of 18 PAAs were detected, of which 14 were quantified, with 4,4'-diaminodiphenylmethane (4,4'-MDA) and aniline being the most prevalent ones.
