Salvage Treatment for Extragonadal Germ Cell Tumours: High-Dose Chemotherapy and Autologous Stem Cell Transplantation Outcomes-A Single-Centre Experience.

Extragonadal germ cell tumours have a more unfavourable prognosis than gonadal germ cell tumours. We aimed to evaluate the survival analysis, response rates, and factors affecting responses to high-dose chemotherapy (HDCT) and autologous stem cell transplantation (ASCT) in patients with relapsed/refractory extragonadal germ cell tumours. This study included patients diagnosed with extragonadal germ cell tumours who underwent HDCT + ASCT between November 2016 and January 2023 at Gülhane Training and Research Hospital.

Transcriptomic investigation of NP toxicity on HepaRG spheroids.

Metal nanoparticles (NPs) are commonly used nanomaterials, however concerns have been raised about their toxicity. Although a few studies have reported the toxicity of NPs on cells, they have generally been restricted to a limited variety of NPs, inappropriate cell lines, or culture methods. Thus, the adverse effects remain inadequately understood, necessitating further analysis.

Multimodality Imaging in Cardiomyopathies.

Cardiomyopathy, which is shortly defined as a disease of the myocardium, has a broad definition that includes many different diagnoses. Recent advances in cardiac imaging techniques, including basic and advanced echocardiography, computed tomography, nuclear medicine, and cardiac magnetic resonance, allow for a more accurate evaluation of volumes and thickness of cardiac chambers, systolic and diastolic function of the ventricules, and tissue structure. Multimodality imaging often provides the first clinical suspicion for specific etiologies, especially when the medical and family history is unclear, by identification of red flags of underlying systemic diseases.

Functional and Social Recovery and Outcomes After Extracorporeal Membrane Oxygenation Support in COVID-19 Patients.

With the COVID pandemic, veno-venous (VV) extracorporeal membrane oxygenation (ECMO) was implanted in many patients around the world. Data regarding follow-up and recovery of patients who are placed on ECMO support after COVID-related acute respiratory distress syndrome (ARDS) or ARDS for any other reason are limited. In our study, we share the 1 year follow-up results and cardiopulmonary exercise test results of the discharged patients.

CAP-RNAseq: an integrated pipeline for functional annotation and prioritization of co-expression clusters.

Cluster analysis is one of the most widely used exploratory methods for visualization and grouping of gene expression patterns across multiple samples or treatment groups. Although several existing online tools can annotate clusters with functional terms, there is no all-in-one webserver to effectively prioritize genes/clusters using gene essentiality as well as congruency of mRNA-protein expression. Hence, we developed CAP-RNAseq that makes possible (1) upload and clustering of bulk RNA-seq data followed by identification, annotation and network visualization of all or selected clusters; and (2) prioritization using DepMap gene essentiality and/or dependency scores as well as the degree of correlation between mRNA and protein levels of genes within an expression cluster.

Early Systolic Lengthening Is Associated with SYNTAX Score in Patients with Non-ST-Elevation Acute Coronary Syndrome.

In the present study, we aimed to evaluate the relationship between early systolic lengthening and anatomic SYNTAX score in troponin (-) and (+) groups among patients with non-ST-elevation acute coronary syndrome (ACS).

Methods: A total of 95 patients diagnosed with non-ST-elevation ACS were included in the prospective, non-randomized, single-center study.

Aim: Description of patient characteristics, effectiveness and safety in Turkish patients treated with pazopanib for metastatic soft tissue sarcoma (STS).

Patients And Methods: This multicenter study is based on retrospective review of hospital medical records of patients (≥ 18 years) treated with pazopanib for non-adipocytic metastatic STS at 37 Oncology clinics across Turkey. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS) and overall survival (OS) were evaluated with further analysis of data on the three most common histological subtypes (leiomyosarcoma [LMS], undifferentiated pleomorphic sarcoma [UPS], synovial sarcoma [SS]) in the cohort.

A low dose of RBD and TLR7/8 agonist displayed on influenza virosome particles protects rhesus macaque against SARS-CoV-2 challenge.

Influenza virosomes serve as antigen delivery vehicles and pre-existing immunity toward influenza improves the immune responses toward antigens. Here, vaccine efficacy was evaluated in non-human primates with a COVID-19 virosome-based vaccine containing a low dose of RBD protein (15 µg) and the adjuvant 3M-052 (1 µg), displayed together on virosomes. Vaccinated animals (n = 6) received two intramuscular administrations at week 0 and 4 and challenged with SARS-CoV-2 at week 8, together with unvaccinated control animals (n = 4).

Poxvirus MVA Expressing SARS-CoV-2 S Protein Induces Robust Immunity and Protects Rhesus Macaques From SARS-CoV-2.

Novel safe, immunogenic, and effective vaccines are needed to control the COVID-19 pandemic, caused by SARS-CoV-2. Here, we describe the safety, robust immunogenicity, and potent efficacy elicited in rhesus macaques by a modified vaccinia virus Ankara (MVA) vector expressing a full-length SARS-CoV-2 spike (S) protein (MVA-S). MVA-S vaccination was well tolerated and induced S and receptor-binding domain (RBD)-binding IgG antibodies and neutralizing antibodies against SARS-CoV-2 and several variants of concern.

Ischaemic versus non-ischaemic: how does heart failure aetiology affect pulmonary arterial capacitance and pulmonary artery pulsatility index in end-stage heart failure?

Background: The aetiology of heart failure may have different effects on right ventricular (RV) function, pulmonary pressures and RV afterload. Pulmonary arterial capacitance (PAC) and pulmonary artery pulsatility index (PAPi) are novel haemodynamic indices used in determining RV afterload and RV function, respectively. We aimed to investigate whether there was a difference in PAC and PAPi between ischaemic cardiomyopathy (ICMP) and non-ischaemic cardiomyopathy (NICMP) in patients with end-stage heart failure.
