Physiologically Based Pharmacokinetic (PBPK) Models are routinely used in drug development and therefore appear frequently in marketing authorization applications (MAAs) to the European Medicines Agency (EMA). For a model to be a key source of evidence for a regulatory decision, it must be considered qualified for the intended use. Advice on the data expected to allow qualification of a PBPK model or platform is provided in the EMA Guideline on the reporting of PBPK modeling and simulation.

The key recommendation from the conference was for NCI to develop a premiere communication-specific population survey to track health and cancer communication-related phenomena. This led to NCI developing and launching HINTS in 2003.

While a timely diagnosis reduces the risk of complications and improves health outcomes, diagnostic delays (DDs) are common. Our study used narratives and data from patient-reported outcome measures (PROMs) of individuals diagnosed with IBD to examine: (1) What factors helped or hindered achieving a timely diagnosis of IBD? and (2) how do DDs relate to PROMs?
Methods: We conducted a mixed-methods study of 296 individuals diagnosed with IBD in Canada.
Background: The Gender Equity Initiative in Global Surgery organization launched a mentorship program to address the limited opportunities available in low-and-middle-income countries (LMICs). We aimed to evaluate the utility of the virtual program in bridging this critical gap.
Methods: A retrospective review of program surveys containing quantitative and qualitative questions from 2022 to 2023 was performed.
Background: Mycobacterium cell wall fraction (MCWF) is derived from nonpathogenic Mycobacterium phlei and is used as an immunomodulatory compound in clinical practice, yet its mode-of-action requires further research.
Objective: To evaluate the host response to MCWF in canine peripheral blood mononuclear cells (PBMCs) by using enzyme-linked immunosorbent assays (ELISA) and quantitative reverse transcription (qRT)-PCR for assessment of cytokines.
Animals: Eight healthy Labrador retrievers.
Active ghrelin (AG) is produced through the post-translational addition of n-octanoic acid to the amino residue Ser-3, making it the natural ligand for the ghrelin receptor. The synthesis of AG is contingent upon specific dietary fatty acids as substrates for the acylation process. Prior studies have demonstrated that AG infusion can lead to reduced feed intake (FI) in broiler chickens, suggesting that manipulating AG may serve as an alternative to quantitative feed restriction in broiler breeders.

It is crucial we understand how these changes in inequality may affect how people think and behave. We propose that economic inequality threatens the social fabric of society, in turn increasing moralization-that is, the greater tendency to employ or emphasize morality in everyday life-as an attempt to restore order and control.

However, existing studies on friendship patterns often rely on surveys that assess the perspective of relatively few participants on their friendships but do not measure actualized friendship patterns. Here, we used data from a large Slovakian online social network to assess the role of gender, age, and body mass index (BMI) in same-gender online connections among more than 400,000 users.

As a whole, de novo fermentation and synthetic pathway construction for these molecules remain relatively underexplored and could unlock molecules with exciting new applications in industries ranging from textiles to agrochemicals to pharmaceuticals. Here, we report a mix-and-match co-culture platform to de novo generate a large array of halogenated tryptophan derivatives in Escherichia coli from glucose.
View Article and Find Full Text PDFTetracycline destructases (TDases) are flavin monooxygenases which can confer resistance to all generations of tetracycline antibiotics. The recent increase in the number and diversity of reported TDase sequences enables a deep investigation of the TDase sequence-structure-function landscape. Here, we evaluate the sequence determinants of TDase function through two complementary approaches: (1) constructing profile hidden Markov models to predict new TDases, and (2) using multiple sequence alignments to identify conserved positions important to protein function.

Despite decades of investigation, there are no known potent, selective small-molecule inhibitors of this enzyme. Here, we report the preclinical characterization of MZ-101, a small molecule that potently inhibits GYS1 in vitro and in vivo without inhibiting GYS2, a related isoform essential for synthesizing liver glycogen.

However, testing for sputum eosinophilia is impractical in most clinical settings.
Objective: We examined associations between sputum eosinophilia and type 2 inflammatory biomarkers in untreated mild persistent asthma.
