Ten simple rules for good model-sharing practices.

Computational models are complex scientific constructs that have become essential for us to better understand the world. Many models are valuable for peers within and beyond disciplinary boundaries. However, there are no widely agreed-upon standards for sharing models.

Developing robust quantitative PCR primers for comparative biomass analysis of Tall Fescue (Festuca arundinacea) and its Epichloë endophyte.

Tall fescue ( ) is a widely adopted forage and turf grass. This is partly due to a fungal endophyte, which confers both abiotic and biotic stress tolerance. Although PCR primers exist to test for endophyte presence, these were not designed to quantitatively analyze the amount of fungus in the plant.

Ancient genomes reveal a deep history of treponemal disease in the Americas.

Human treponemal infections are caused by a family of closely related Treponema pallidum that give rise to the diseases yaws, bejel, pinta and, most famously, syphilis. Debates on both a common origin for these pathogens and the history of syphilis itself has weighed evidence for the "Columbian hypothesis", which argues for an American origin, against that for the "pre-Columbian hypothesis", which argues for presence of the disease in Eurasia in the Medieval period and possibly earlier. While molecular data has provided a genetic basis for distinction of the typed subspecies, deep evolution of the complex has remained unresolved due to limitations in the conclusions that can be drawn from the sparse paleogenomic data currently available.

Population Pharmacokinetics of Meropenem Across the Adult Lifespan.

Background And Objective: We conducted an opportunistic pharmacokinetic study to evaluate the population pharmacokinetics of meropenem, an antimicrobial commonly used to treat Gram-negative infections in adults of different ages, including older adults, and determined optimal dosing regimens.

Methods: A total of 99 patients were included. The population pharmacokinetic models used had two compartments: zero-order input and linear elimination.

Utilizing an Opportunistic Clinical Study and Population-Based Pharmacokinetic Models to Identify Rational Empiric Dosing Regimens for Piperacillin-Tazobactam in Critically Ill Patients.

Determining an effective dosing regimen for piperacillin-tazobactam in critically ill patients is challenging due to substantial pharmacokinetic variability caused by complex pathophysiological changes. To address this need, a prospective clinical study was conducted, which enrolled 112 critically ill patients and employed an opportunistic sampling strategy. Population modeling and simulation were performed to characterize the pharmacokinetics (PK) and probability of target attainment (PTA) of piperacillin-tazobactam under various dosing regimens.
