Soman induces endoplasmic reticulum stress and apoptosis of cerebral organoids via the GRP78‐ATF6‐CHOP signaling pathway

open access: yesFEBS Open Bio, EarlyView.
Cerebral organoids were employed as a novel model to explore the neurotoxicity of soman. Soman inhibited acetylcholinesterase activity, increased cell apoptosis and upregulated endoplasmic reticulum (ER) stress markers glucose‐regulated protein 78 (GRP78), activating transcription factor 6 (ATF6) and C/EBP homologous protein (CHOP).

Suction conditions for minimizing the production of free hemoglobin during blood salvage using an autotransfusion apparatus [PDF]

open access: yesKorean Journal of Anesthesiology, 2011
BackgroundThree kinds of conditions should be considered to reduce free hemoglobin production using an autologous cell salvage device. They are the negative suction pressure, the size of suction tip, and the air contact during suction. We want to examine

A statistical method for estimating the no-observed-adverse-event-level [PDF]

open access: yesarXiv, 2021
In toxicological risk assessment the benchmark dose (BMD) is recommended instead of the no-observed-adverse effect-level (NOAEL). Still a simple test procedure to estimate NOAEL is proposed here, explaining its advantages and disadvantages. Versatile applicability is illustrated using four different data examples of selected in vivo toxicity bioassays.

Patients' Global Impression of Change (PGIC) Score Compared to Monthly Migraine Days to Evaluate Treatment Persistence With Anti‐CGRP Monoclonal Antibodies

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT This study assessed whether continued treatment with anti‐CGRP monoclonal antibodies (mAbs) is driven more by reductions in monthly migraine days (MMDs) or patients' global impression of change (PGIC), a patient‐reported outcome. Among 169 patients treated with anti‐CGRP mAbs, 21.3% discontinued due to ineffectiveness. PGIC responders (≥ 5) at

Similarity of multiple dose-response curves in interlaboratory studies in regulatory toxicology [PDF]

open access: yesarXiv, 2020
To claim similarity of multiple dose-response curves in interlaboratory studies in regulatory toxicology is a relevant issue during the assay validation process. Here we demonstrated the use of dose-by-laboratory interaction contrasts, particularly Williams-type by total mean contrasts.

Serotonergic and Dopaminergic Function in Neuropsychiatrically Asymptomatic People With HIV on Antiretroviral Therapy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective People with HIV (PWH) on antiretroviral therapy (ART) still experience neurocognitive dysfunction and accelerated brain volume loss. To assess whether the serotonergic and dopaminergic systems are affected, we used [11C]DASB positron emission tomography (PET) to assess presynaptic serotonergic function and [18F]FDOPA PET to measure ...
