Nutrition and Female Fertility: An Interdependent Correlation

Besides ageing, a number of non-modifiable lifestyle-related factors, as smoking, elevated consumption of caffeine and alcohol, stress, agonist sports, chronic exposure to environmental pollutants, and other nutritional habits exert a negative impact on women’s fertility. In particular, metabolic disorders including diabetes, obesity, and hyperlipidemia commonly associated to hypercaloric diets are suspected to promote infertility in women either by direct damage to oocyte health and differentiation, or by indirect interference with the pituitary-hypothalamic axis, resulting in dysfunctional oogenesis. Obese women show decreased insulin sensitivity determining persistent hyperinsulinemia, which may be involved in the pathogenesis of Polycystic Ovary Syndrome. Thus the reduced insulin secretion induced by dietary adjustments is an attractive non-pharmacological treatment for preventing infertility and the Mediterranean diet aimed at maintening normal body mass may be effective in preservation of ovarian health and physiology. Furthermore, in relation to the oxidative stress as a co-factor of defective oocyte maturation, an appropriate intake of proteins, antioxidants and methyl-donor supplements (1-Carbon Cycle) may decrease the bioavailability of toxic oxidants and protect the oocyte differentiation.

CONCLUSIONS Our results highlight that interaction of Nr4a1 and LKB1 can mitigate T2DM by activating the AMPK/SIRT1 signaling pathway and inhibiting NF-kappaB activation. This may offer new insight for T2DM treatment. PMID: 31939452 [PubMed - in process]

Ureaplasma urealyticum (uu) is one of the most common agents of urogenital infections and is associated with complications such as infertility, spontaneous abortion and other sexually transmitted diseases. Here, a DNA sensor based on oligonucleotide target-specific gold nanoparticles (AuNPs) was developed, in which the dispersed and aggregated states of oligonucleotide-functionalised AuNPs were optimised for the colorimetric detection of a polymerase chain reaction (PCR) amplicon of U. urealyticum DNA. A non-cross-linking approach utilising a single Au-nanoprobe specific of the urease gene was utilised and the effect of a ...

This study reported a simple and inexpensive method for determination of 10-hydroxy-2-decenoic acid (10-HDA) and free amino acids in different royal jelly based dietary supplement samples using a purpose-made dual-channeled capillary electrophoresis (CE) system with capacitively coupled contactless conductivity detection (C4D). The objective of the work is to propose a tool for food / quality control activities that can be realizable even with a modest infrastructure. 10-HDA and free amino acids were analyzed using the background electrolyte (BGE) solutions composed of 20 mM Tris(hydroxymethyl)aminomethane adjusted ...

Driving blood glycaemia from hyperglycaemia to euglycaemia as fast as possible while avoiding hypoglycaemia is a major problem for decades for type-1 diabetes and is solved in this study. A control algorithm is designed that guaranties hypoglycaemia avoidance for the first time both from the theory of positive systems point of view and from the most pragmatic clinical practice. The solution consists of a state feedback control law that computes the required hyperglycaemia correction bolus in real-time to safely steer glycaemia to the target. A rigorous proof is given that shows that the control-law respects the positivity ...
