The Role of Sex in the Effects of Smoking and Nicotine in Cardiovascular Function, Atherosclerosis, and Inflammation.

Introduction: Cigarette smoke (CS) invokes an inflammatory response associated with vascular dysfunction and atherosclerosis. The role of sex and nicotine in CS effects on cardiovascular function and atherosclerosis is unexplored.

Methods: Male and female C57Bl/6 WT (wild type) and ApoE-/- mice were exposed to CS and nicotine with access to chow and water ad libitum for 16 weeks to fill this gap.

Effects of Berries, Phytochemicals, and Probiotics on Atherosclerosis through Gut Microbiota Modification: A Meta-Analysis of Animal Studies.

Atherosclerosis is a major cause of death and disability. The beneficial effects of phytochemicals and probiotics on atherosclerosis have gained significant interest since these functional foods can improve inflammation, oxidative stress, and microbiome dysbiosis. The direct effect of the microbiome in atherosclerosis, however, needs further elucidation.

The Impact of Dietary Supplementation of Whole Foods and Polyphenols on Atherosclerosis.

The purpose of this review is to highlight current research on the benefits of supplementation with foods with a diverse polyphenol composition, including fruits, vegetables, nuts, grains, oils, spices, and teas in blunting atherosclerosis. We searched PubMed for publications utilizing whole food or polyphenols prepared from whole foods in Apolipoprotein E (ApoE) or Low-Density Lipoprotein Receptor (LDLR) knockout mice, and identified 73 studies in which plaque was measured. The majority of the studies reported a reduction in plaque.

Nicotine in Senescence and Atherosclerosis.

Cigarette smoke is a known exacerbator of age-related pathologies, such as cardiovascular disease (CVD), atherosclerosis, and cellular aging (senescence). However, the role of nicotine and its major metabolite cotinine is yet to be elucidated. Considering the growing amount of nicotine-containing aerosol use in recent years, the role of nicotine is a relevant public health concern.
