The use of choline supplementation for the prevention of chemotherapy-related cognitive impairments.

FASEB J 2022 May;36 Suppl 1

University of South Florida, Tampa, FL.

The majority of patients who report chemotherapy-related cognitive deficits are women. Many chemotherapeutic agents suppress ovarian function, decreasing circulating estrogen. Because estrogen regulates high affinity choline uptake (HACU) and HACU is the rate-limiting step for acetylcholine (ACh) synthesis, chemotherapeutic agents may indirectly impair cholinergic mediated cognitive processes.

Chronic Stress Accelerates the Progression of Cerebrovascular Dysfunction with Alzheimer's Disease.

FASEB J 2022 May;36 Suppl 1

West Virginia University, Morgantown, WV.

Vascular contributions to cognitive impairment and dementia are a key pathology associated with Alzheimer's disease (AD). Past work in our lab has shown that chronic stress induces cerebrovascular dysfunction due to a pro-oxidative environment while epidemiological studies suggest a link between chronic stress and dementia. With this in mind, we tested the hypothesis that chronic stress accelerates the vascular pathology associated with AD potentially via the xanthine oxidase pathway. Read More

Sex Differences in Hydrogen Peroxide-Induced K Channel Activation in Arterioles of Ischemic Myocardium after Exercise Training.

FASEB J 2022 May;36 Suppl 1

Texas A&M University, College Station, TX.

The objective of this study was to determine sex differences in potassium (K ) channel contribution to H O -mediated dilation after exercise training in arterioles distal to chronic coronary artery occlusion. We tested the hypothesis that females would have enhanced H O -mediated vasodilation compared to males through enhanced coupling of H O with large-conductance, calcium-dependent K (BKCa; iberiotoxin 100 nM) channels and 4-aminopyridine (4-AP; 1 mM)-sensitive voltage-gated K (Kv). Adult Yucatan miniature swine were surgically instrumented with an Ameroid constrictor around the proximal left circumflex coronary artery, which gradually induced occlusion and created a collateral-dependent vascular bed.

Does hormonal therapy improve sperm retrieval rates in men with non-obstructive azoospermia: a systematic review and meta-analysis.

Hum Reprod Update 2022 May 8. Epub 2022 May 8.

Department of Urology, Imperial Healthcare NHS Trust, Charing Cross Hospital, London, UK.

Background: The beneficial effects of hormonal therapy in stimulating spermatogenesis in patients with non-obstructive azoospermia (NOA) and either normal gonadotrophins or hypergonadotropic hypogonadism prior to surgical sperm retrieval (SSR) is controversial. Although the European Association of Urology guidelines state that hormone stimulation is not recommended in routine clinical practice, a significant number of patients undergo empiric therapy prior to SSR. The success rate for SSR from microdissection testicular sperm extraction is only 40-60%, thus hormonal therapy could prove to be an effective adjunctive therapy to increase SSR rates. Read More
