Dosage Optimization Using Physiologically Based Pharmacokinetic Modeling for Pediatric Patients with Renal Impairment: A Case Study of Meropenem.

The pharmacokinetics of renally eliminated antibiotics can be influenced by changes associated with renal function and development in a growing subject. Little is known about the effects of renal insufficiency on the pharmacokinetics of meropenem in pediatric subjects. The aim of this study was to develop a physiologically based pharmacokinetic (PBPK) model of meropenem for pediatric patients that can be used to optimize meropenem dosing in pediatric patients with renal impairment (RI).

Regenerative Functions of Regulatory T Cells and Current Strategies Utilizing Mesenchymal Stem Cells in Immunomodulatory Tissue Regeneration.

Background: Regulatory T cells (Tregs) are essential for maintaining immune homeostasis and facilitating tissue regeneration by fostering an environment conducive to tissue repair. However, in damaged tissues, excessive inflammatory responses can overwhelm the immunomodulatory capacity of Tregs, compromising their functionality and potentially hindering effective regeneration. Mesenchymal stem cells (MSCs) play a key role in enhancing Treg function.

Determinants of Indoor NO and PM Concentration in Senior Housing with Gas Stoves.

Nitrogen dioxide (NO) and particulate matter of 2.5 microns (PM) are air pollutants that impact health, especially among vulnerable populations with respiratory disease. This study identifies factors influencing indoor NO and PM in low-income households of older adults with asthma who use gas stoves in Lowell, Massachusetts.

Comparative Diagnostic Efficacy of Ultrasonography and Radiography for Gas Embolism in Loggerhead () Turtles.

Sea turtles face numerous threats, often stemming from human activities, resulting in high mortality rates. One of the primary risks they encounter is posed by fishing activities. In the South Adriatic Sea, the extensive trawling fleet often impacts sea turtles, and in recent years, a specific disorder, known as gas embolism (GE), and the associated disease known as decompression sickness (DCS), has emerged as a new threat.

Pilot-scale adsorption of pharmaceuticals from municipal wastewater effluent using low-cost magnetite-pine bark: Regeneration/enumeration of viable bacteria with a study on their biotoxicity.

A low-cost and renewable magnetite-pine bark (MPB) sorbent was evaluated in continuous-flow systems for the removal of various pharmaceuticals from municipal wastewater effluent following membrane bioreactor (MBR) treatment. A 33-day small-scale column test (bed volume: 791 cm) was conducted using duplicate columns of biochar (BC, Novocarbo) and activated carbon (AC, ColorSorb) as reference for two columns of BC and MPB in order to compare the efficiency of AC and MPB. After the small-scale column test, the pharmaceutical concentrations were generally below the detection limit.
