Enhancement of biological effects of oxidised nano- and microplastics in human professional phagocytes.

Micro and nanoplastics are ubiquitous pollutants that can cause adverse health effects even in humans. Effects of virgin and oxidised (simulating the aging processes) polystyrene nano (nPS) and micro particles (mPS) with diameters of 0.1 and 1 µm were studied on human professional phagocytes (i.

Increased long-term bleeding complications in females undergoing endovascular revascularization for peripheral arterial disease.

Objective: Females with peripheral arterial disease (PAD) treated with endovascular interventions have increased limb-based procedural complications compared with males. Little is known regarding long-term bleeding risk in these patients who often require long-term antiplatelet or anticoagulation therapy. We hypothesize that females have a higher incidence of bleeding events compared with males in the year after endovascular intervention for PAD.

Hormone replacement therapy in menopausal women: Past problems and future possibilities.

Oral administration of conjugated equine estrogens (CEE) with and without the synthetic progestin medroxyprogesterone acetate (MPA) in postmenopausal women is associated with side-effects that include increased risk of stroke and breast cancer. The current evidence that transdermal administration of estradiol may provide a safer alternative to orally administered CEE is reviewed. Transdermally administered estradiol has been shown to be an efficacious treatment for hot flushes possibly without the increase in blood clotting that is associated with administration of oral CEE.

The potential of 5-hydryoxytryptophan for hot flash reduction: a hypothesis.

Hormone replacement therapy (HRT) is contraindicated in women with a history of breast cancer or a high risk of breast cancer development. Recent results from large clinical trials, such as the Women's Health Initiative, have demonstrated increased risks of thromboembolic events and a moderate increased risk of breast cancer in women using conjugated estrogens and progestogens. There is a need for viable non-hormonal alternative treatments to HRT, such as nutritional and botanical therapies, in this population of women, who tend to experience more significant vasomotor symptoms.

A pilot study to examine a combination botanical for the treatment of menopausal symptoms.

Objective: Hormone replacement therapy has become a controversial treatment for symptoms of menopause, leading many women and their physicians to search for safer, effective alternatives. Certain botanicals are known to contain phytoestrogenic activity, which may be helpful in alleviating menopausal symptoms. We report the results of a study using a combination botanical supplement to treat menopausal symptoms.
