BACKGROUND: Impairments in cognitive function are difficult to evaluate and measure. In most cases, subjects do not perceive any alteration in their own status, particularly in case of mild cognitive impairment. In case of minimal alterations of cognitive function, no real treatment exists at the moment. Functional and/or temporary alterations in the cerebral microcirculation may be involved in cognitive impairment, and some aspects of MCI may be theoretically caused by perfusional problems...

Beige adipocytes in white adipose tissue (WAT) have received considerable recognition because of their potential protective effect against obesity. Pycnogenol (PYC), extracted from French maritime pine bark, has anti-inflammatory and antioxidant properties and can improve lipid profiles. However, the effect of PYC on obesity has never been explored. In this study, we investigated the effects of PYC on obesity and WAT browning in apolipoprotein E- (ApoE-) deficient mice. The results showed that PYC treatment clearly reversed body weight and the mass of eWAT gain resulting from a high-cholesterol and high-fat diet (HCD), but no difference in food intake...

BACKGROUND: The standardized maritime pine bark extract (Pycnogenol®) has previously shown symptom alleviating effects in patients suffering from moderate forms of knee osteoarthritis (OA). The cellular mechanisms for this positive impact are so far unknown. The purpose of the present randomized pilot controlled study was to span the knowledge gap between the reported clinical effects of Pycnogenol® and its in vivo mechanism of action in OA patients. METHODS: Thirty three patients with severe OA scheduled for a knee arthroplasty either received 100 mg of Pycnogenol® twice daily or no treatment (control group) three weeks before surgery...

Oxidative stress plays a critical task in the biochemical and pathological alteration linked with myocardial ischemic-reperfusion injury (IRI). This warrants identifying agents with a potential for preventing such damage in an effective way. A novel plant based product, Pycnogenol, obtained from the French maritime pine (Pinus pinaster ssp. atlantica) bark extract was known for its tremendous antioxidant potential (both in vivo, in vitro). It was able to attenuate the symptoms of immune dysfunction through restoring a cellular antioxidant status in low micronutrient-induced immune deficient mice...

This review summarizes the effects of the standardized proprietary bark extract of the French maritime pine (Pycnogenol® ) in mild osteoarthritis (OA), stage 1 and 2. The extract exerts antioxidative, anti-inflammatory, and chondroprotective effects in vitro and in vivo. Its phenolic acids as well as catechin and taxifolin are quickly absorbed. Active metabolites, produced by gut microbiota in the intestinal tract from oligomeric procyanidins, appear in blood 6 h following ingestion and remain for at least 14 h, providing a long-lasting flow of anti-inflammatory substances for relief of OA symptoms...

Natural standardized flavonoid extract from the bark of Pinus pinaster, Pycnogenol (Pyc), was recently found to decrease intensively the activity of sarcoplasmic reticulum Ca2+ -ATPase of rabbit skeletal muscle (SERCA1). On the basis of this inhibitory effect in a cell-free system and similarities of SERCA1 to its other isoforms, proapoptotic properties of Pyc may be expected in cellular systems. Pycnogenol (40-100 μg/mL) induced a concentration-dependent decrease of the viability of pancreatic INS-1E β cells associated with induction of apoptosis...

Cardiovascular diseases (CVDs) are one of the major causes of mortality and disability in Western countries. Prevention is known to be the cornerstone to lessen the incidence of CVDs and also to reduce the economic burden of both the citizen and the healthcare system. "Interventional medicine" certainly puts lifestyle modification as the first therapeutic step, including a healthy diet and physical activity. Secondly, a large body of research individuated a number of food and plant bioactives, which are potentially efficacious in preventing and reducing some highly prevalent CV risk factors, such as hypercholesterolemia, hypertension, vascular inflammation and vascular compliance...
