Article Synopsis
  • - In vitro assessments for predicting pharmacokinetic (PK) behavior in biotherapeutics help identify potential issues early in drug discovery, reducing excessive animal testing and optimizing resources.
  • - The study highlights the value of integrating in vitro measures, particularly those assessing nonspecific interactions and FcRn interactions, as they correlate well with drug clearance in a specific mouse model.
  • - A computational method is proposed to enhance the correlation to PK by combining various in vitro measurements with multivariate regression, allowing for better prioritization of drug candidates with ideal PK profiles.

Introduction: The tyrosine kinase inhibitors (TKIs) sorafenib and lenvatinib represent the first-line systemic therapy of choice for patients with hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT). Under sorafenib and lenvatinib, HCC patients have shown increasingly improved overall survival in clinical studies over the years. In contrast, data on overall survival for patients with HCC recurrence after LT under TKIs are scarce and limited to small retrospective series.

Oxidative stress in patients suffering from obstructive sleep apnea syndrome (OSAS) is associated with a low-grade systemic inflammation, immune disturbance, and increased invasion of monocytes into the endothelium. Besides continuous positive airway pressure (PAP), hypoglossal nerve stimulation (HNS) has become a promising treatment option for patients with OSAS. We aimed to analyse the influence of HNS therapy on the cellular characteristics relevant for adhesion and immune regulation of circulating CD14/CD16 monocyte subsets.

Obstructive sleep apnea syndrome (OSAS) and obesity go hand in hand in the majority of patients and both are associated with a systemic inflammation, immune disturbance and comorbidities such as cardiovascular disease. However, the unambiguous impact of OSAS and obesity on the individual inflammatory microenvironment and the immunological consequences of human monocytes has not been distinguished yet. Therefore, aim of this study was to investigate the impact of OSAS and obesity related factors on the inflammatory microenvironment by performing flow cytometric whole blood measurements of CD14/CD16 monocyte subsets in normal weight OSAS patients, patients with obesity but without OSAS, and patients with OSAS and obesity, compared to healthy donors.

Article Synopsis
  • African swine fever (ASF) is a deadly viral disease affecting pigs, originating from Africa, and has been spreading in Europe and Asia since its emergence in Georgia in 2007.
  • In Ukraine, the highest number of ASF outbreaks occurred in 2017 and 2018, with a notable spread pattern moving from eastern and northern borders towards western and southern regions.
  • The analysis indicates that while wild boars played a key role in early ASF spread, human activities have become the main driver in recent years, with effective mitigation strategies leading to a decline in outbreaks since 2019, though complete eradication remains a challenge.
