Relationship between autophagy and NLRP3 inflammasome during articular cartilage degradation in oestrogen-deficient rats with streptozotocin-induced diabetes.

Background: Estrogen deficiency and Diabetes mellitus (DM) cause joint tissue deterioration, although the mechanisms are uncertain. This study evaluated the immunoexpression of autophagy and NLRP3-inflammasome markers, in rat articular cartilage with estrogen deficiency and DM.

Methods: Twenty rats were sham-operated (SHAM) or ovariectomized (OVX) and equally allocated into four groups: SHAM and OVX groups administered with vehicle solution; SHAM and OVX groups treated with 60 mg/kg/body weight of streptozotocin, intraperitoneally, to induce DM (SHAM-DM and OVX-DM groups).

Effect of modified citrus pectin on galectin-3 inhibition in cisplatin-induced cardiac and renal toxicity.

This study evaluated the effect of pharmacological inhibition of galectin 3 (Gal-3) with modified citrus pectin (MCP) on the heart and kidney in a model of cisplatin-induced acute toxicity. Male Wistar rats were divided into four groups (n = 6/group): SHAM, which received sterile saline intraperitoneally (i.p.

Effects of melatonin and metformin on the ovaries of rats with polycystic ovary syndrome.

Objective: To study the combined and isolated effects of melatonin and metformin in the ovarian tissue of rats with PCOS.

Design: Experimental study using a rat model of PCOS induced by continuous light exposure.

Intervention(s): Forty adult female rats were divided into 5 groups: physiological estrus phase (Sham); permanente estrus with PCOS induced by continuous lighting exposure for 60 consecutive days (control); with PCOS treated with melatonin; with PCOS treated with metformin; with PCOS treated with melatonin + metformin.

Lack of Annexin A1 Exacerbates Inflammatory Response in Acute Endometritis Model.

Annexin A1 (AnxA1) is a glucocorticoid-inducible protein and an important endogenous modulator of inflammation. However, its effect in the endometrial microenvironment is poorly explained. This study aimed to evaluate the role of endogenous AnxA1 in an endometritis mouse model induced by lipopolysaccharide (LPS).

The Effects of ESC/ESH-Based Written Generic Lifestyle Advice and a Nutraceutical on 24-Hour Blood Pressure in Patients with High-Normal Office Blood Pressure and Low-Moderate Cardiovascular Risk.

(1) Background: Lifestyle changes, eventually coupled with a nutraceutical, are recommended strategies for managing high-normal blood pressure (BP) patients with low-moderate cardiovascular (CV) risk. In a real-life clinical setting, we evaluated the effects of generic written lifestyle advice, extrapolated from the 2018 ESC/ESH guidelines, and a beetroot-based nutraceutical on 24 h BP in a population with a high-normal office BP and low-moderate CV risk. (2) Methods: A longitudinal observational study was conducted in two ESH Hypertension Excellence Centres on 43 consecutive subjects with high-normal BP according to repeated office BP (OBP) measurements and a low-moderate CV risk based on SCORE2/SCORE2-OP.
