Determining the Optimum Number of Ground Control Points for Obtaining High Precision Results Based on UAS Images

open access: yes, 2018
Ground control points (GCPs) are used in the process of indirectly georeferencing Unmanned Aerial Systems (UAS) images. A minimum of three ground control points (GCPs) is required but increasing the number of GCPs will lead to higher accuracy of the ...

A phase 1 evaluation of inhaled oxytocin: Physiologically‐based pharmacokinetic model informed dosing of a novel heat‐stable oxytocin delivery system

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim To develop and validate a physiologically‐based pharmacokinetic (PBPK) model enabling inhaled oxytocin dose selection for clinical evaluation. Subsequently, to conduct a phase 1 study investigating the pharmacokinetics and safety of selected doses of an optimized inhaled oxytocin product in healthy, non‐pregnant female participants.

Preserved Spermatogenesis and Hormonal Function in Men Receiving a Pretomanid Regimen (BPaMZ) for Pulmonary Drug‐Resistant Tuberculosis

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Pretomanid is a component of the World Health Organization‐recommended treatment regimen for drug‐resistant tuberculosis in patients aged ≥ 14 years. While preclinical rodent studies identified testicular toxicity as a potential clinical liability at elevated doses, no corresponding effects were observed in nonhuman primates nor clinical hormone ...
