Quantification of growth hormone in serum by isotope dilution mass spectrometry [PDF]

, 2009
Inter-assay variation of antibody based routine tests is hampering comparability of measurement results for growth hormone (GH) between different laboratories and decision making in clinical practice. Here it is demonstrated, that quantification of GH by

Mechanistic Learning for Predicting Survival Outcomes in Head and Neck Squamous Cell Carcinoma

CPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 540-550, March 2025.
ABSTRACT We employed a mechanistic learning approach, integrating on‐treatment tumor kinetics (TK) modeling with various machine learning (ML) models to address the challenge of predicting post‐progression survival (PPS)—the duration from the time of documented disease progression to death—and overall survival (OS) in Head and Neck Squamous Cell ...

Comparison of Recycled Polypropylene Sourced From Food and Nonfood Applications for Direct Food Contact Use

Packaging Technology and Science, EarlyView.
Utilisation of postconsumer recycled (PCR) plastic for food contact has safety concerns due to the potential presence of unapproved intentionally/non‐intentionally added substances, which can pose health and environmental risks if not removed during recycling.

Rapid quantification and validation of etomidate and dexmedetomidine blood concentrations in rats using a novel portable mass spectrometer

Frontiers in Veterinary Science
In clinical anesthesia, precise dosing depends on feedback from blood drug concentrations. However, rapid tools for measuring these concentrations are currently limited.

Nanoplastics Impair GnRH Neuron Migration and Neuroendocrine Function: Emerging Players in the Pathogenesis of Reproductive Disorders

Small, EarlyView.
Little is known about the effects of polystyrene nanoplastics (PS‐NPs) on gonadotropin releasing hormone (GnRH) neurons, which control puberty onset and fertility. By applying tailored in vitro GnRH neuron models, this article shows how PS‐NPs are internalized and impact hormone secretion and cell migration, through gene expression changes. Ultimately,

Analytical measuring interval, linearity, and precision of serology assays for detection of SARS-CoV-2 antibodies according to CLSI guidelines

mSphere
Serology testing is commonly used to evaluate the immunogenicity of COVID-19 vaccines and measure antibodies as a marker of previous infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Iowa Population Exposures to Metals and Metalloids in Well Water

Environmental Toxicology, EarlyView.
ABSTRACT Previous Iowa studies suggest low levels and chronic arsenic exposures are associated with prostate cancer. The rural Iowa population heavily relies on private wells for drinking water resources and thus is vulnerable to contaminants such as heavy metals found in well water.

Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

Environmental Toxicology, EarlyView.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.

Mycotoxins‐contaminated wheat matrices bioconversion by Tenebrio molitor larvae (Coleoptera: Tenebrionidae)

Insect Science, EarlyView.
Larval development time, ADG, survival rate and substrate consumption were not negatively affected by the levels of mycotoxins contamination Larvae excreted most of the ingested DON and its derivatives through exuviae and frass The mycotoxin accumulation rates observed in larvae were always below the current legal limits for livestock feed Abstract ...
