The effect of n-3 long-chain polyunsaturated fatty acids and lipoic acid on the heart in the ovariectomized rat model of menopause.

The effect of n-3 long-chain polyunsaturated fatty acids and lipoic acid on the heart in the ovariectomized rat model of menopause. Free Radic Res. 2019 May 20;:1-231 Authors: Marinho PM, Salomon TB, Andrade AS, Behling CS, Putti JS, Benfato MS, Schäfer Hackenhaar F Abstract Menopause occurs as consequence of ovarian senescence that leads to a drop of oestrogen hormone. The decreased oestrogen levels combined with the impairment of the redox system may contribute to the increased risk of postmenopausal cardiovascular disease. Supplementation with antioxidants may be an alternative to reduce cardiovascular risk. The study evaluated the effect of dietary supplementation with docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA) and alpha-lipoic acid (LA) for a period of 16 weeks on oxidative stress biomarkers in the hearts of ovariectomized 3-months-old rats. Ovariectomy did not increase the level of the damage markers malondialdehyde and carbonyl, and both were decreased by LA supplementation. Ovariectomy increased the levels of the endogenous antioxidants glutathione, vitamin C and H2O2 consumption, after restoration by DHA, EPA and LA supplementation. Vitamin E, glutathione peroxidase, glutathione S-transferase and superoxide dismutase are not altered by ovariectomy. Lipid and protein damage are not increased after ovariectomy and a portion of the endogenous antioxidants concomitantly increased, suggesting that hearts may be protected by thes...

CONCLUSIONS: Since the last version of this review, only a few new relevant studies have provided additional findings with supporting evidence to suggest that infertility drugs may increase the risk of ovarian cancer slightly in subfertile women treated with infertility drugs when compared to the general population or to subfertile women not treated. The risk is slightly higher in nulliparous than in multiparous women treated with infertility drugs, and for borderline ovarian tumours. However, few studies have been conducted, the number of cancers is very small, and information on the dose or type of fertility drugs used i...

ConclusionsWhile AELB is comparable to estradiol in alleviating menopause-like behavior, it has distinct brain-uterus mechanisms in association with the predominant protection of catecholamine synthesis, neurotrophins, and ERβ receptors in brain, but with minor effects on uterus. AELB and its constituents may be novel treatments for menopause.Graphical abstract

ConclusionWe confirm previous studies showing that the PTPN2 protein is lost in half of the breast cancer cases and gene deletion occurs in 15 –18% of the cases. Furthermore, the results suggest that the role of PTPN2 is subtype-related and should be further investigated to assess how this could affect breast cancer prognosis and treatment response.

In conclusion, tamoxifen induces a rise in serum IGFBP-1 suggesting a systemic, possibly hepatic effect, whilst LNG abrogates this in both the liver and endometrium. Impact statement What is already known on this subject? Previous reports of the use of LNG-IUS in women on tamoxifen have provided conflicting evidence as to whether the endometrium exhibited decidualisation or not. These reports were however based solely on histological examination and lacked supporting biochemical data. What do the results of this study add? After 12 months of treatment with LNG-IUS, the endometria of women on tamoxifen show histologi...

Authors: Sparavigna A, Tenconi B, La Penna L Abstract Purpose: Onychoschizia causes lamellar splitting of the nail plate. It is a common problem seen by dermatologists therefore, an effective treatment is needed. The aim of this study was to evaluate the efficacy and tolerability of a biomineral formulation (Biomineral Unghie) applied topically, and/or as an oral supplement, in subjects with onychoschizia. Patients and methods: This single center, randomized, parallel-group, open-label study was conducted between March 2017 and June 2017. Fifty non-menopausal females aged 18 years or over with onychoschizia we...
