Article Abstract
The optimization of conical intersection structures is complicated by the nondifferentiability of the adiabatic potential energy surfaces. In this work, we build a pseudodiabatic surrogate model, based on Gaussian process regression, formed by three smooth and differentiable surfaces that can adequately reproduce the adiabatic surfaces. Using this model with the restricted variance optimization method results in a notable decrease of the overall computational effort required to obtain minimum energy crossing points.

Cefepime (FEP), a fourth-generation cephalosporin combined with tazobactam (TAZ), a β-lactamase inhibitor, is being developed by Wockhardt as a pharmacodynamically optimized fixed dose combination (FEP-2 g + TAZ-2 g) for the treatment of multidrug-resistant Gram-negative infections. To undertake an exposure-response analysis for establishing pharmacokinetic (PK)/pharmacodynamic (PD) targets, it is crucial to characterize the PK profile of compounds in surrogate compartments, such as plasma and lung, in clinically relevant animal infection models used to evaluate efficacy. In the current study, PKs of FEP and TAZ were assessed in plasma and in epithelial lining fluid (ELF) of neutropenic noninfected, lung-infected, and thigh-infected mice.

A rapid and specific liquid chromatography-tandem mass spectrometry method with a wide linear range was developed and validated for the simultaneous quantification of Vitamin K1 (VK1) trans- and cis- isomers in human plasma. Bovine serum albumin solution (15%) served as a surrogate matrix for preparing the calibrators to establish the quantitative curves. After liquid-liquid extraction, VK1 trans- and cis- isomers in plasma samples were separated on a ChromCore C30 column (15 cm × 4.

Purpose: To determine if melatonin-enriched culture media could offset loss of imprinting in mouse concepti.
Methods: Zygotes were cultured to blastocyst stage under optimized conditions in melatonin-supplemented media at either 10 M (MT 10) or 10 M (MT 10), or without supplementation (Culture + embryo transfer, or ET, positive control). Blastocysts were also developed in vivo (ET negative control).

Preclinical animal testing has played a critical role within medical history. Yet it remains an underdiscussed topic within the medical humanities. What might happen, then, if we analyse the animal studies of the lab via the method of cultural critique that is animal studies? This essay responds to this question by exploring the roles that animals play, and are made to play, within the technologies for, debates about and narratives of human reproduction.

Introduction: Traffic signals are the controlling devices aimed to reduce crossing conflicts at intersections. However, rear-end and lane-changing conflicts at signalized intersection approaches are a significant problem. This work aims to proactively assess and spatially map the safety and risk at signalized intersection approaches by field data collection and microsimulation modeling using PTV-VISSIM.
