Spectral and molecular insights into the variations of dissolved organic matter in shallow groundwater impacted by surface water recharge.

Dissolved organic matter (DOM) represents one of the most active elements in aquatic systems, whose fraction is engaged in chemical and biological reactions. However, fluorescence, molecular diversity and variations of DOM in groundwater systems with the alteration of surface water recharge remain unclear. Herein, Excitation-emission matrix (EEM) fluorescence spectroscopy and Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) combined with principal component coefficients, parallel factor analyses (PARAFAC) with two‒dimensional correlation spectroscopy (2D-COS) were applied in this study.

Safety and clinical efficacy of neoadjuvant chemoradiation therapy with immunotherapy for organ preservation in ultra-low rectal cancer: preliminary results of the CHOICE-I trial: a prospective cohort study.

Objective: To explore the safety and efficacy of neoadjuvant chemoradiotherapy (nCRT) combined with a PD-1 antibody in improving complete clinical response (cCR) and organ preservation in patients with ultra-low rectal cancer.

Methods: This was a prospective phase II, single-arm, open-label trial. Patients with confirmed pMMR status T1-3aN0-1M0 retcal adenocarcinoma were included.

DKC1-mediated pseudouridylation of rRNA targets hnRNP A1 to sustain IRES-dependent translation and ATF4-driven metabolic adaptation.

The pseudouridine synthase DKC1 regulates internal ribosome entry site (IRES)-dependent translation and is upregulated in cancers by the MYC family of oncogenic transcription factors. We investigated the functional significance of DKC1 in MYCN-amplified neuroblastoma and its underlying mechanisms. A key function of DKC1 is to promote an ATF4-mediated gene expression program for amino acid metabolism and stress adaptation.

Streamlined Access to Peptidoglycan Biosynthesis Terminator GlcNAc-1,6-anhydro-MurNAc.

GlcNAc-1,6-anhydro-MurNAc is a key peptidoglycan elongation terminator of biological and medicinal importance. Herein, we present a concise approach to this molecule in 12 steps with an overall 25% yield using d-glucosamine as the sole starting material. Our synthesis features the formation of a 1,6-anhydro-MurNAc building block by an intramolecular glycosylation and the selective conversion of the phthalimido group of the MurNPhth moiety, paving the way for antibiotics with a new killing mechanism by targeting bacterial transglycosylase.
