Behavioral Analyses in Dark Agouti Rats Following Repeated Systemic Treatment With Fingolimod (FTY720).

Background: Studies in experimental animals revealed that acute and chronic treatment with small-molecule immunosuppressive drugs lead to neurobehavioral alterations in rodents.

Methods: Against this background, this study investigated behavioral alterations in rats after repeated administration of FTY720, an immunosuppressive drug used for the treatment of multiple sclerosis, employing the open field, elevated plus maze, and dark/light tests.

Results: Compared to controls, repeated FTY720 treatment affected behavior in rats, reflected by a reduction in distance traveled as well as increased time engaged in freezing in the open field and elevated plus maze.

Functional characterization of OR51B5 and OR1G1 in human lung epithelial cells as potential drug targets for non-type 2 lung diseases.

Background: Hypersensitivity to odorants like perfumes can induce or promote asthma with non-type 2 inflammation for which therapeutic options are limited. Cell death of primary bronchial epithelial cells (PBECs) and the release of the pro-inflammatory cytokines interleukin-6 (IL-6) and IL-8 are key in the pathogenesis. Extra-nasal olfactory receptors (ORs) can influence cellular processes involved in asthma.

HBV shows different levels of adaptation to HLA class I-associated selection pressure correlating with markers of replication.

Background & Aims: Immune responses by CD8 T cells are essential for control of HBV replication. Although selection of escape mutations in CD8 T-cell epitopes has been previously described in HBV infection, its overall influence on HBV sequence diversity and correlation with markers of HBV replication remain unclear.

Methods: Whole-genome sequencing was applied to HBV isolates from 532 patients with chronic HBV infection and high-resolution HLA class I genotyping.

A ruptured craniocervical junction perimedullary arteriovenous fistula successfully treated through flow diversion: A case report.

Background: Spinal arteriovenous fistulae (AVF) located at the craniocervical junction (CCJ) are rare and usually present with hemorrhage. Bleeding is usually attributed to arterial feeders arising from the anterior spinal artery (ASA) and aneurysms located on such feeders. Perimedullary AVFs are typically found on the ventral surface of the spinal cord, which makes them difficult to treat through traditional microsurgical methods.

Allogeneic Hematopoietic Stem Cell Transplantation in Refractory Multiple Myeloma-A Retrospective Multicenter Analysis.

A growing list of therapies available for patients with multiple myeloma (MM) results in deep response rates, but eventually almost all patients relapse. Allogeneic hematopoietic cell transplantation (allo-SCT) is a familiar approach for MM, but responses are often short and side effects burdensome. Simultaneously, allo-SCT provides a unique platform on which novel immune therapies can be employed to improve clinical outcomes.

Implementation of socio-economic variables in risk adjustment systems: A quantitative analysis using the example of Germany.

At least in Western Europe, competitive social health insurance systems have implemented systems of morbidity-based risk adjustment to establish a level playing field for insurers. However, insured persons with specific socio-economic characteristics are still underfunded, leaving incentives for risk selection. In Germany, there is an ongoing debate about (re)implementing socio-economic variables to reduce this undercompensation.

Ion Mobility QTOF-MS Untargeted Lipidomics of Human Serum Reveals a Metabolic Fingerprint for GNE Myopathy.

GNE myopathy, also known as hereditary inclusion body myopathy (HIBM), is a rare genetic muscle disorder marked by a gradual onset of muscle weakness in young adults. GNE myopathy (GNEM) is caused by bi-allelic variants in the UDP--acetylglucosamine 2-epimerase (UDP-GlcNAc 2-epimerase)/-acetylmannosamine kinase (ManNAc kinase) gene (), clinically resulting in the loss of ambulation within 10-20 years from the onset of the initial symptoms. The disease's mechanism is poorly understood and non-invasive biomarkers are lacking, hindering effective therapy development.

Real-world characteristics and treatment of cardiac transthyretin amyloidosis: A multicentre, observational study.

Aims: Data on the clinical profiles of patients with transthyretin amyloidosis cardiomyopathy (ATTR-CM) in the post-approval era of tafamidis 61 mg are lacking. Study aims were characterization of contemporary ATTR-CM patients, analysis of potential eligibility for the 'Transthyretin Amyloidosis Cardiomyopathy Clinical Trial' (ATTR-ACT) and identification of factors associated with the decision on tafamidis 61 mg treatment.

Methods And Results: This retrospective study analysed ATTR-CM patients seen at eight University Hospitals in the first year after approval of tafamidis 61 mg for ATTR-CM in Germany (April 2020 to March 2021).

The COSMOS Registry of CytoSorb Hemoadsorption Therapy in Critically Ill Patients: Protocol for an International, Prospective Registry.

Background: Extracorporeal blood purification with CytoSorb has been increasingly used as an adjunctive therapy in several hyperinflammatory critical care conditions, as well as to remove elevated levels of myoglobin or bilirubin in patients with rhabdomyolysis or liver failure. Despite the increasing worldwide use of hemoadsorption, data from large international multicenter studies are still lacking.

Objective: The COSMOS (CytoSorb Treatment Of Critically Ill Patients) registry is a company-sponsored registry by CytoSorbents Corporation and CytoSorbents Medical Inc.

Histidine containing dipeptides protect epithelial and endothelial cell barriers from methylglyoxal induced injury.

Integrity of epithelial and endothelial cell barriers is of critical importance for health, barrier disruption is a hallmark of numerous diseases, of which many are driven by carbonyl stressors such as methylglyoxal (MG). Carnosine and anserine exert some MG-quenching activity, but the impact of these and of other histidine containing dipeptides on cell barrier integrity has not been explored in detail. In human proximal tubular (HK-2) and umbilical vein endothelial (HUVEC) cells, exposure to 200 µM MG decreased transepithelial resistance (TER), i.

Pathogenic mitochondrial DNA mutations inhibit melanoma metastasis.

Mitochondrial DNA (mtDNA) mutations are frequent in cancer, yet their precise role in cancer progression remains debated. To functionally evaluate the impact of mtDNA variants on tumor growth and metastasis, we developed an enhanced cytoplasmic hybrid (cybrid) generation protocol and established isogenic human melanoma cybrid lines with wild-type mtDNA or pathogenic mtDNA mutations with partial or complete loss of mitochondrial oxidative function. Cybrids with homoplasmic levels of pathogenic mtDNA reliably established tumors despite dysfunctional oxidative phosphorylation.

Enhancing treatment approaches for postpneumonectomy empyema: exploring the role of video-assisted thoracic surgery.

Introduction: Postpneumonectomy empyema (PPE) poses a substantial postoperative risk, even in the absence of a bronchopleural fistula, often necessitating surgical intervention for resolution.

Aim: To evaluate the efficacy of video-assisted thoracic surgery (VATS) in managing PPE, supported by a comprehensive review of pertinent literature.

Material And Methods: Six studies were included in this analysis, encompassing 63 PPE cases treated with VATS.
