Inflammaging and neurodegenerative diseases: Role of NLRP3 inflammasome activation in brain atherosclerotic vascular disease.

The activation of the NLRP3 inflammasome-IL-1β pathway has been clearly shown to be involved in the pathophysiology of cardiovascular diseases, but its role in cerebral atherosclerotic vascular disease has not been fully clarified. Here we provide an overview on the current knowledge about the relevance of the activation of this mechanism in the onset of acute brain atherosclerotic vascular disease and the subsequent tissue damage. Some variants of NLRP3-related genes seem to reduce the susceptibility to acute ischaemic stroke in selected cohorts, although no clear evidence exists either supporting or excluding any role of this pathway in its pathophysiology.

Anti-Müllerian Hormone, Growth Hormone, and Insulin-Like Growth Factor 1 Modulate the Migratory and Secretory Patterns of GnRH Neurons.

Anti-Müllerian hormone (AMH) is secreted by Sertoli or granulosa cells. Recent evidence suggests that AMH may play a role in the pathogenesis of hypogonadotropic hypogonadism (HH) and that its serum levels could help to discriminate HH from delayed puberty. Moreover, the growth hormone (GH)/insulin-like growth factor 1 (IGF1) system may be involved in the function of gonadotropin-releasing hormone (GnRH) neurons, as delayed puberty is commonly found in patients with GH deficiency (GHD) or with Laron syndrome, a genetic form of GH resistance.

Interactions of Oxysterols with Atherosclerosis Biomarkers in Subjects with Moderate Hypercholesterolemia and Effects of a Nutraceutical Combination ( BB536, Red Yeast Rice Extract) (Randomized, Double-Blind, Placebo-Controlled Study).

Background: Oxysterol relationship with cardiovascular (CV) risk factors is poorly explored, especially in moderately hypercholesterolaemic subjects. Moreover, the impact of nutraceuticals controlling hypercholesterolaemia on plasma levels of 24-, 25- and 27-hydroxycholesterol (24-OHC, 25-OHC, 27-OHC) is unknown.

Methods: Subjects ( = 33; 18-70 years) with moderate hypercholesterolaemia (low-density lipoprotein cholesterol (LDL-C:): 130-200 mg/dL), in primary CV prevention as well as low CV risk were studied cross-sectionally.

Hydromethanolic Extracts from L. Edible Parts Positively Modulate Pathophysiological Mechanisms Related to the Metabolic Syndrome.

Metabolic syndrome includes a cluster of risk factors for many pathological conditions, including hyperglycemia, abdominal obesity, hyperlipidemia, and hypertension. L. (also known as baobab) is used in traditional African Medicine and recent studies showed that it improves the metabolism of carbohydrates and lipids.

Oxidative Stress Modulation by Cameroonian Spice Extracts in HepG2 Cells: Involvement of Nrf2 and Improvement of Glucose Uptake.

Oxidative stress plays a relevant role in the progression of chronic conditions, including cardiometabolic diseases. Several Cameroonian plants, including spices, are traditionally used as herbal medicines for the treatment of diseases where oxidative stress contributes to insulin resistance, like type 2 diabetes mellitus. This study evaluated the antioxidant capacity and the effects on oxidative-stress-induced impairment of glucose uptake of 11 Cameroonian spice extracts.
