Background: Heart failure is accompanied by abnormalities in ventricular-vascular interaction due to increased myocardial and arterial stiffness. Galectin-3 is a recently discovered biomarker that plays an important role in myocardial and vascular fibrosis and heart failure progression.
Objectives: The aim of this study was to determine whether galectin-3 is correlated with arterial stiffening markers and impaired ventricular-arterial coupling in decompensated heart failure patients.
Methods: A total of 79 inpatients with acute decompensated heart failure were evaluated. Serum galectin-3 was determined at baseline, and during admission, transthoracic echocardiography and measurements of vascular indices by Doppler ultrasonography were performed.
Results: Elevated pulse wave velocity and low arterial carotid distensibility are associated with heart failure in patients with preserved ejection fraction (p = 0.04, p = 0.009). Pulse wave velocity, carotid distensibility and Young's modulus did not correlate with serum galectin-3 levels. Conversely, raised galectin-3 levels correlated with an increased ventricular-arterial coupling ratio (Ea/Elv) p = 0.047, OR = 1.9, 95% CI (1.0‑3.6). Increased galectin-3 levels were associated with lower rates of left ventricular pressure rise in early systole (dp/dt) (p=0.018) and raised pulmonary artery pressure (p = 0.046). High galectin-3 levels (p = 0.038, HR = 3.07) and arterial pulmonary pressure (p = 0.007, HR = 1.06) were found to be independent risk factors for all-cause mortality and readmissions.
Conclusions: This study showed no significant correlation between serum galectin-3 levels and arterial stiffening markers. Instead, high galectin-3 levels predicted impaired ventricular-arterial coupling. Galectin-3 may be predictive of raised pulmonary artery pressures. Elevated galectin-3 levels correlate with severe systolic dysfunction and together with pulmonary hypertension are independent markers of outcome.

Department of oncology, the First Affiliated Hospital of Zhengzhou University, Zhengzhou, Henan 450052, China.
Purpose: The objective of this study was to explore the relationship among serum levels of the growth-stimulating expressed gene 2 protein (ST2), Galectin-3(GAL-3), N-terminal pro-B-type natriuretic peptide (NT-proBNP) in elderly hypertensive patients and heart failure with preserved ejection fraction (HFpEF).
Materials And Methods: Eighty-five elderly hypertensive patients with HFpEF were registered as the HFpEF group, and 46 hypertensive patients without HF were registered as the Non-HF group. The levels of serum sST2 (soluble ST2), Galectin-3, and NT-proBNP were measured, and related indexes of heart function were performed with echocardiography in two groups, respectively.

The Fontan operation has become the primary palliative treatment for patients with a functionally univentricular heart. The population of patients with Fontan circulation is constantly growing and aging. As the number of Fontan patients surviving into adulthood increases, there is a clear need for research on how best to follow these patients and manage their complications.

Research Question: Does metformin reverse endometriosis-associated infertility?
Design: Endometriosis was induced by transplanting uterus fragments from B6CBAF1 mice into recipients of the same strain. The mice were divided into groups: endometriosis (End, n = 24), sham-operated (Sham, n = 12), endometriosis with metformin (0.5mg/ml) orally administered for 3 months (EndMet, n = 21) and sham-operated metformin-treated (ShamMet, n = 16).

Background: Chronic periodontitis is associated with various systemic inflammatory diseases; however, research on its association with chronic kidney disease (CKD) is relatively limited. Because both conditions share common risk factors, systemic inflammation plays a key role in the progression of these diseases. Galectin-3 (Gal-3) is a proinflammatory cytokine that plays an important role in chronic inflammatory diseases and is a potential biomarker.
