Semimicro Determination of COD Employing Microwave Digestion
Environmental Engineering Science, 2003 A modified semimicro method is described for determining chemical oxygen demand (COD) employing microwave (MW) digestion (0.5 min exposure at 1,000 W power, and 10 min exposure at 250 W power) with a titration assessment. Composition of reaction mixture was the same as that of the usual reflux method.

Soil sample preparation using microwave digestion for uranium analysis [PDF]
, 2000 A new sample preparation procedure has been developed for digestion of soil samples for uranium analysis. The technique employs a microwave oven digestion system to digest the sample and to prepare it for separation chemistry and analysis.

ERα–PADI4–CXCL8 Axis Drives MDSC‐Mediated Immune Evasion in Anaplastic Thyroid Carcinoma
Advanced Science, EarlyView.MAPK‐driven ligand‐independent ERα activation drives PADI4 transcription and translation. This enzyme then modifies CXCL8 chemokines through citrullination, generating a potent chemoattractant gradient specifically for myeloid‐derived suppressor cells.

Advanced Science, EarlyView.This study reveals that large tumors secrete more chemokine CXCL3, which recruits immunosuppressive neutrophils to the periphery, thereby impairing the activation and memory of systemic tumor‑reactive CD8+ T cells. CXCL3 antagonism restores systemic immune memory and enhances the antitumor efficacy of anti‑PD‑1 therapy, offering a potential strategy to

Improvement of the digestion of cattle slurry via the process of co-digestion
, 2011 The use of maize (Zea mays) as a co-substrate with cattle slurry for the production of biogas was investigated in detail by running several long term digestion trials under different operational conditions in laboratory scale semi-continuous digesters ...

Advanced Science, EarlyView.Incomplete microwave ablation induces animmunosuppressive microenvironment in tumor‐draining lymph nodes. An albumin‐based lipoprotein nanosystem enables coordinated delivery of immunomodulators to tumor‐draining lymph nodes and residual tumors, reverses post‐ablation immunosuppression, suppresses residual tumor growth, and promotes durable antitumor ...

Molecular Glue Degraders of TEM β‐Lactamases by Periplasmic Protease DegP
Angewandte Chemie, EarlyView.Molecular glues are developed that target TEM‐family β‐lactamases to the bacterial protease DegP for degradation. β‐Lactamase inhibitor tazobactam is identified as accelerating TEM β‐lactamase degradation by DegP, which is further enhanced by linkerless incorporation of dipeptides enriched among DegP substrates.

Comparative study on open system digestion vs. microwave-assisted digestion methods for trace element analysis in agricultural soils [PDF]
, 2014 The aim of this work was to evaluate two different digestion procedures for the determination of the concentration of trace and major elements (As, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, P, Pb, Sb, V, Zn) in five hundred randomly selected soil samples from ...
