FEBS Open Bio, EarlyView.NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Reduction of MTT to formazan by cell-free extracts. [PDF]
, 2019 Mid-log E. coli (OD600 = 0.5) was incubated with or without 5.0 mM histidine for 60 min at 37 oC in PBS/glucose. The cells were washed and disrupted by French press.

Advanced Healthcare Materials, EarlyView.Nanoemulsion delivery of a TLR7 agonist enhances safety and promotes colocalization with Leishmania‐infected macrophages in skin lesions, enabling a ∼2‐log reduction in parasite burden. However, tissue‐level constraints and TLR‐driven regulatory feedback generate a mixed immune response that limits complete parasite clearance.

Advanced Healthcare Materials, EarlyView.An ionic naphthalimide AIE photosensitizer (PS), TPAPV‐NIM‐M, anchors to cellular and bacterial membranes, emits in the far‐red/near‐infrared (NIR) region, and efficiently generates reactive oxygen species (ROS) under white light. Its membrane‐localized photodynamic action drives apoptosis/ferroptosis‐mediated tumor suppression and broad‐spectrum ...

TLC demonstration that NADH and GSH reduce NBT to the same formazan product with different kinetics. [PDF]
, 2022 Arrowheads show the origin and final solvent front; UV light was absorbed in the TLC plate by NADH and NBT at the origin, and by diformazan at the arrow. Reduced formazan had an Rf value ranging from 0.42 to 0.44 [38] depending on whether the lane was in
