Ten years of the manufacturing classification system: a review of literature applications and an extension of the framework to continuous manufacture.

The MCS initiative was first introduced in 2013. Since then, two MCS papers have been published: the first proposing a structured approach to consider the impact of drug substance physical properties on manufacturability and the second outlining real world examples of MCS principles. By 2023, both publications had been extensively cited by over 240 publications.

Offline 20 Hz transcranial alternating current stimulation over the right inferior frontal gyrus increases theta activity during a motor response inhibition task.

Objectives: Previous studies have shown that the right inferior frontal gyrus (rIFG) and the pre-supplementary motor area (preSMA) play an important role in motor inhibitory control. The aim of the study was to use theta frequency transcranial alternating current stimulation (tACS) to modulate brain activity in the rIFG and preSMA and to test the effects of stimulation using a motor response inhibition task.

Methods: In four sessions, 20 healthy participants received tACS at 6 Hz over preSMA or rIFG, or 20 Hz over rIFG (to test frequency specificity), or sham stimulation before task processing.

Acute Effects of Air Pollution and Noise from Road Traffic in a Panel of Young Healthy Adults.

Panel studies are an efficient means to assess short-term effects of air pollution and other time-varying environmental exposures. Repeated examinations of volunteers allow for an in-depth analysis of physiological responses supporting the biological interpretation of environmental impacts. Twenty-four healthy students walked for 1 h at a minimum of four separate occasions under each of the following four settings: along a busy road, along a busy road wearing ear plugs, in a park, and in a park but exposed to traffic noise (65 dB) through headphones.

Quantitative X-Ray Microcomputed Tomography Assessment of Internal Tablet Defects.

Physical tablet defects are related to internal structural defects that are not easily assessed by the traditional methods, such as dusting, laminating, or fracturing during appearance, friability, or hardness testing. Also, these methods do not allow objective and quantitative investigation of the role of formulation and process variables, which is essential for quality-by-design drug product development. In this study, an X-ray microcomputed tomography (XμCT) method to analyze internal tablet defects is developed using tablets from a quality-by-design design-of-experiment study.

Tumor cell-specific inhibition of MYC function using small molecule inhibitors of the HUWE1 ubiquitin ligase.

Deregulated expression of MYC is a driver of colorectal carcinogenesis, necessitating novel strategies to inhibit MYC function. The ubiquitin ligase HUWE1 (HECTH9, ARF-BP1, MULE) associates with both MYC and the MYC-associated protein MIZ1. We show here that HUWE1 is required for growth of colorectal cancer cells in culture and in orthotopic xenograft models.

Impulsive-like behavior in differential-reinforcement-of-low-rate 36 s responding in mice depends on training history.

Prior behavioral history in operant conditioning paradigms may induce impulsive-like responding as shown in rats. Little is known to what extent behavioral history influences subsequent behavior in mice, therefore the present study investigated the effects of lever-pressing under a fixed-ratio 5 schedule of reinforcement on subsequent differential-reinforcement-of-low-rate (DRL) 36 s performance in wild type mice compared to the behavior of 5-HT1B receptor knockout mice. Acquisition of both autoshaping and fixed-ratio 5 training was faster in 5-HT1B receptor knockout compared to wild type mice.
