Recyclable All‐in‐One Organo‐Photo‐Auxiliaries Enabling (sp3)C−(sp3)C Coupling Reactions with Diverse Functionalities

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Photochemical C−C coupling reactions can be tailored to industrial chemical processes and preparations of pharmaceuticals. Recent approaches in this area are limited to using precious transition metal coordination complexes that facilitate light absorption and redox processes with benchtop chemicals. Herein, we propose a paradigm that involves

Control of DNA minor groove width and Fis protein binding by the purine 2-amino group. [PDF]

open access: yes, 2013
The width of the DNA minor groove varies with sequence and can be a major determinant of DNA shape recognition by proteins. For example, the minor groove within the center of the Fis-DNA complex narrows to about half the mean minor groove width of ...

Cancer stem-like properties and gefitinib resistance are dependent on purine synthetic metabolism mediated by the mitochondrial enzyme MTHFD2

open access: yesOncogene, 2018
Tumor recurrence is attributable to cancer stem-like cells (CSCs), the metabolic mechanisms of which currently remain obscure. Here, we uncovered the critical role of folate-mediated one-carbon (1C) metabolism involving mitochondrial ...

Cost‐Effective Hierarchical Cobalt Nanostructured Laser‐Induced Graphene for Enhanced Uric Acid Detection

open access: yesAdvanced Sensor Research, EarlyView.
A one‐step electrochemical strategy is utilized to develop a flexible, enzyme‐free biosensor for the sensitive detection of uric acid (UA). The hierarchical cobalt nanostructures synergistically enhance the performance of the biosensor, resulting in a broad detection range of 5 to 700 µM with a sensitivity of 6.75 µA µM−1 cm−2 and a low detection limit

Deep Supramolecular Language Processing for Co‐Crystal Prediction

open access: yesAngewandte Chemie, EarlyView.
DeepCocrystal is a deep learning model that predicts co‐crystal formation by learning supramolecular interactions from molecular string representations. It achieves high accuracy, estimates uncertainty, and offers interpretable insights into its predictions. Validated prospectively, DeepCocrystal discovered novel diflunisal co‐crystals and is available

Intestinal Inflammation as a Dysbiosis of Energy Procurement: New Insights into an Old Topic

open access: yesGut Microbes, 2021
Inflammatory bowel disease (IBD) coincides with profound shifts in microbiota and host metabolic energy supply and demand. The gastrointestinal epithelium is anatomically positioned to provide a selective barrier between the anaerobic luminal microbiota ...

Emerging Therapeutic Strategies for Hearing Loss

open access: yesAdvanced Therapeutics, EarlyView.
Challenges still exist in treating hearing loss in cases of severe damage to hair cells or spiral ganglion neurons. Here, a schematic diagram of cochlear sensory hair cells and auditory nerves is presented. It is found that in normal Corti organs, hair cells have upright stereocilia at the top and auditory neurons at the base. Ototoxic drugs, noise, or

Purine-pyrimidine symmetry, determinative degree and DNA [PDF]

open access: yesarXiv, 2000
Various symmetries connected with purine-pyrimidine content of DNA sequences are studied in terms of the intruduced determinative degree, a new characteristics of nucleotide which is connected with codon usage. A numerological explanation of CG pressure is proposed. A classification of DNA sequences is given.
