- ABSTRACT Violae tianshanicae herba (VTH), a widely used crude drug in Uyghur medicine in China, is renowned for its immunomodulatory, anti-inflammatory, antibacterial, antiviral, and antidiabetic activities, with notable efficacy in treating asthma. However, systematic research on its quality markers (Q-markers) remains limited, underscoring the need to analyze its chemical composition to enable effective quality control. A high-performance liquid chromatography (HPLC) […]

- I didn't know Dr. Amina Woods as well as you'd guess considering the 20+ years we were doing mass spectometry stuff in the same city. We'd spoken a few times, most recently maybe two or three years ago and I was always a fan of her work and presentations of it. What a person she must have been to have inspired […]
- Our library doesn't subscribe to this journal, and I don't have $50 to spend on one paper, so it sure was handy for the authors to put links in the abstract to the -OpenLC Github! There is a repository with .STL files you'll need to print adapters and the code you can use to over-write the original OpenTrons one.There are a […]

- The structural and functional characteristics of membrane proteins can be influenced by the composition of the membrane. Consequently, native membranes are most relevant for the study of receptors and other membrane proteins. In this study, we investigated two types of cell-derived vesicles: natively shed extracellular vesicles (EVs) and mechanically derived vesicles (MVs). To this end, we utilized the human breast […]
- Conventional platinum-based catalysts for alkaline hydrogen evolution reaction (HER) are hindered by the sluggish water dissociation, which is necessary to generate the crucial Pt–H* intermediates. Herein, a distinct mechanism is developed to produce Pt–H* for efficient alkaline HER by diffusing activated lattice hydrogen of the metal hydride supports directly. Meanwhile, water dissociation takes place separately to replenish lattice hydrogen at […]
- ABSTRACT Nanomaterials with amorphous surface have attracted significant attention in the oxygen evolution reaction (OER), which still needs further investigations. In this work, we developed a novel Salt-regulated confinement loading method to prepare amorphous Mn3CoOx support confined FeO microcrystallites at a relatively low-temperature (623 K). The confined FeO microcrystallites showed strong interfacial electronic interactions with Mn3CoOx matrix (abundant defect sites and […]
- ABSTRACT Semaglutide, a glucagon-like peptide-1 receptor agonist, stands as a paradigm of successful peptide drug development. Although absorption, distribution, metabolism and excretion characteristics of semaglutide have been thoroughly studied in both animals and humans, a reliable in vitro screening model for evaluating metabolic behavior of semaglutide and other peptides remains an unmet need in drug development. This study established a novel […]

- Background & Aims: Early identification of decompensation in patients with cirrhosis is important to enable timely detection, management of complications and for effective treatment. This study investigates the biology of decompensation and aim to identify protein biomarkers for identification of high-risk patients. Methods: The primary analysis included plasma samples from 46 patients with metabolic dysfunction associated steatotic liver disease (MASLD) […]
- Pulmonary tuberculosis (PTB) remains a major global public health challenge. Existing diagnostic approaches are generally limited by suboptimal sensitivity, prolonged turnaround times, high costs, and reliance on sputum samples. These constraints hinder large-scale implementation in resource-limited settings and substantially impede early screening and timely intervention. Targeting the characteristic expression of {beta}-lactamase in Mycobacterium tuberculosis, this study employed systematic screening of […]

- I was initially a little appalled by the amount of optimization of diaPASEF windows in this paper, but I read more of it while walking a mean little dog in the rain and there is a lot here. Food science is very different that your run-of-the-mill proteomics samples. Often the thing you're worried about is the allergenic peptidome, and those sure […]

- ABSTRACT Solvent mismatch between the two dimensions is one of the main limitations in two-dimensional liquid chromatography (2D-LC) and presents a significant challenge for method development. Although 2D-LC provides a powerful means to increase peak capacity for oligonucleotides analysis compared to conventional one-dimensional LC, solvent incompatibility remains a major obstacle that discourages broader development of such methods. In this work, […]

- Background: Diabetic vascular complications are driven by endothelial dysfunction, yet the role of 3D genome organization in this process is unknown. We sought to define the alterations in chromatin architecture in diabetic endothelium and identify the key regulators involved. Methods: We generated a high-resolution 3D epigenomic atlas of diabetic endothelial cells from mouse models and human subjects using H3K27ac HiChIP, […]

- Filamentous fungi, such as Aspergillus species, use microtubule transport to move early endosomes. Other cargos, such as peroxisomes and mRNAs, "hitchhike" on early endosomes to move throughout the long hyphae of these organisms. In Aspergillus nidulans, peroxisomes hitchhike on early endosomes using the endosomal protein PxdA and the peroxisomal protein AcbdA. The HookA adaptor protein links endosomes to microtubule motors.
