Background: Apelin, an endogenous peptide, has recently gained attention due to its positive inotropic effects in heart failure physiopathology. We investigated the relationship between serum apelin levels and the severity of calcific aortic stenosis (AS).
Methods: A total of 68 consecutive patients diagnosed with calcific AS and a control group of 32 subjects were included in the study. The subjects were divided into three group as follows: the control group, the mild-moderate AS group and the severe AS group. Blood samples were obtained from all of the subjects, which were used for biochemical comparisons of apelin 36 and high-sensitive C-reactive protein (hsCRP) levels.
Results: Plasma apelin 36 levels were significantly lower in the patients with severe AS [490 (247-1074) pg/ml] compared to both the mild-moderate AS [209 (97-453) pg/ml] and control [660 (378-1200) pg/ml] groups (p < 0.001). Correlation analysis between the left ventricular mass index and apelin concentrations revealed a significant negative correlation between the two parameters (p < 0.001, r = -0.478).
Conclusions: Our study demonstrated decreased apelin levels and increased hsCRP concentrations in patients with severe calcific AS. Our findings may help to clarify the exact pathophysiologic role of apelin in cardiovascular diseases.

This research investigates the interplay between Reactive Oxygen Species (ROS) and Apelin (APLN) in regulating autophagy, with implications for placental cell senescence and apoptosis in pre-eclampsia (PE). We manipulated APLN expression using sgRNA to study its effects on ROS levels and subsequent cellular responses. Our findings reveal that APLN overexpression elevates ROS production, accelerating cellular senescence and apoptosis.

Thromboembolic disorders, including deep vein thrombosis (DVT) and pulmonary embolism (PE), are major global health concerns, causing significant morbidity and mortality. Early diagnosis is crucial for effective treatment and improved patient outcomes. Recent research has identified Apelin-13, a bioactive peptide in the apelin family, as a promising diagnostic biomarker for Thromboembolic disorders.

Objective: To assess whether alterations in maternal serum apelin-13 levels differ between early-onset preeclampsia (EO-PE) and late-onset preeclampsia (LO-PE).
Materials And Methods: A prospective case-control study included 90 preeclamptic cases and 90 normotensive healthy pregnant women as controls. Preeclampsia cases were subclassified as EO-PE and LO-PE.

Background: Hypothyroidism (HT) is associated with numerous well-characterized comorbidities and established biomarkers for subclinical atherosclerosis which may lead to an elevated risk of cardiovascular disease; however, the precise molecular mechanism underlying these pathological features remains elusive. Increased levels of adipokines may have adverse effects on multiple atherosclerotic risk factors in HT. Different studies have evaluated the association between HT and adipokines with conflicting results.

Ischemic-anoxic injury plays an important role in the pathophysiology of diabetes retinopathy, optic neuropathy, even glaucoma and other ocular diseases. It may ultimately cause damage to neuronal death like retinal ganglion cells (RGCs) and subsequent visual loss. RGCs are essential elements of the retina and optic nerve that are crucial to visual formation.
