What Is QSP and Why Does It Exist?: A Brief History.

Quantitative systems pharmacology (QSP) is a modeling approach employed in drug research and development that combines mechanistic representations of biological processes with drug pharmacology to deepen biological understanding and predict the responses to novel drugs or protocols. QSP has evolved from and is related to other modeling approaches, but has a number of unique attributes and applications. Here, we clarify the definition of QSP and its key features, trace its evolution, briefly compare it to other approaches, and explain why and how it can be used to reduce risk and improve efficiency in drug research and development.

Autocrine TGF-β1 drives tissue-specific differentiation and function of resident NK cells.

Group 1 innate lymphoid cells (ILCs) encompass NK cells and ILC1s, which have non-redundant roles in host protection against pathogens and cancer. Despite their circulating nature, NK cells can establish residency in selected tissues during ontogeny, forming a distinct functional subset. The mechanisms that initiate, maintain, and regulate the conversion of NK cells into tissue-resident NK (trNK) cells are currently not well understood.

A narrative review of present knowledge and digital approaches in orthognathic surgery.

Introduction: Anomalies of jaw position and shape affect approximately 10 % of the population. They can have a significant impact on quality of life, which is why the continuous improvement of therapeutic approaches is a key concern in oral and maxillofacial surgery. The aim of this narrative review article is to examine the development of orthognathic surgery in the context of traditional and innovative methods.

Inflammatory Waldenström Macroglobulinemia is associated with clonal hematopoiesis: a multicentric cohort.

Inflammation in Waldenström Macroglobulinemia (iWM) predicts outcomes after immuno-chemotherapy and BTK inhibitors, but its origin is unknown. Here, we unravel increased clonal hematopoiesis in iWM patients (61% versus 23% in non-inflammatory WM), suggesting a contribution of environmental cells to iWM.

Mass Spectrometric and Immunologic Detection of Prolactin-Derived Vasoinhibin in Human Serum.

Background: Circulating levels of the antiangiogenic protein, vasoinhibin, derived from the proteolytic cleavage of prolactin (PRL), in prolactinoma are unknown, as is the molecular nature of its isoforms. Dimerization of recombinant vasoinhibin has been reported.

Methods: Vasoinhibin in a human serum sample was identified by using preparative electrophoresis with subsequent SDS-PAGE and Western blot analysis, as well as mass spectrometry (MS) and ELISA.
