SU5416, 3-(3,5-dimethyl-1H-pyrrol-2-ylmethylene)-1,3-dihydro-indol-2-one, is a potent inhibitor of vascular endothelial growth factor (VEGF) receptor tyrosine kinase, Flk-1/KDR (fetal liver kinase 1/kinase insert domain-containing receptor), also known as VEGF receptor 2 (VEGFR2). It was the first VEGFR2 inhibitor to enter clinical trials for the treatment of colorectal and non-small cell lung cancers. Pre-clinical evaluation of SU5416 included studies related to the distribution, metabolism and excretion of this compound. These studies have provided information useful in understanding the disposition and metabolism of the indolinone class of chemicals, which has not been studied previously with therapeutic intent. The lessons we learned from SU5416 have been successfully applied in developing next generation indolinone compounds targeting tumor angiogenesis.

Impact of different pathogen classes on the serum -glycome in septic shock.

The morbidity and mortality of sepsis remain high. Clinicians lack effective markers to rapidly diagnose sepsis and identify the underlying pathogen infection particularly for patients with candidaemia or cases of culture-negative sepsis where culture-based diagnostics are inadequate. In our search for new lines of potential sepsis biomarkers, we here explore the impact of various classes of infectious agents on the serum -glycome in a septic shock cohort.

Introduction: Our aim was to investigate the insufficiently understood differences in the immune system between anti-citrullinated peptide antibody (ACPA)-positive (ACPA) and ACPA-negative (ACPA) early rheumatoid arthritis (eRA) patients.
Methods: We performed multiple cytokine assays using sera from drug-naïve ACPA and ACPA eRA patients. Additionally, we conducted single-cell RNA sequencing of CD45 cells from peripheral blood samples to analyze and compare the distribution and functional characteristics of the cell subsets based on the ACPA status.

Background: Screening for diabetes in non-traditional settings like emergency departments (ED) can enhance early detection among patients at higher risk for diabetes. This study aims to assess the reach of an ED-based screening program by examining the characteristics of patients screen-detected for diabetes or prediabetes.
Study Design: Retrospective cross-sectional study.

Introduction: The idea that chronic inflammatory processes may play a role in the etiopathogenesis of both treatment - refractory chronic spontaneous urticaria and cardiovascular diseases is an important research topic.
Aim: Within the scope of this research, we aimed to elucidate a new perspective on the follow-up of chronic urticaria patients by evaluating the 10-year cardiovascular risk and metabolic syndrome in resistant chronic spontaneous urticaria patients who were unresponsive to maximum antihistamine treatment.
Material And Methods: A total of 170 individuals who applied to our institution's Health Science University, Tepecik Education and Research Hospital, allergy and immunology outpatient clinic have been analysed in this retrospective case-control study.

Objective: This study aims to explore the role of estrogen in providing cardioprotective benefits to premenopausal women, examining how hormonal differences between sexes influence the prevalence of cardiovascular diseases (CVDs) in women.
Materials And Methods: Eighteen female Wistar rats were equally distributed into three treatment groups. Animals in Group I (sham-operated) and Group II (ovariectomized [OVX]) received oral saline solution at a dose of 2 mL/kg.
