Rodriguez-Carrillo A, Espinoza-Vargas M, Vargas-Ortiz K, Ibarra-Reynoso L, Olvera-Juarez M, Gomez-Ojeda A, et al.
Nutrients . 2025 Feb; 17(3). PMID: 39940261
Background: Metabolic-dysfunction-associated steatotic liver disease (MASLD) and obesity contribute to vascular dysfunction through oxidative stress, heightening cardiovascular risk. Oral supplementation with L-citrulline (L-cit), a precursor of L-arginine (L-arg) and nitric...

Kang Y, Dillon K, Martinez M, Maharaj A, Fischer S, Figueroa A
Nutrients . 2024 Jun; 16(12). PMID: 38931289
Endothelial dysfunction decreases exercise limb blood flow (BF) and muscle oxygenation. Acute L-Citrulline supplementation (CIT) improves muscle tissue oxygen saturation index (TSI) and deoxygenated hemoglobin (HHb) during exercise. Although CIT...

Martinez M, Dillon K, Kang Y, Maharaj A, Fischer S, Figueroa A
Eur J Appl Physiol . 2024 Apr; 124(9):2603-2613. PMID: 38607608
Purpose: Postmenopausal women experience augmented aortic hemodynamic responses to isometric handgrip (IHG) exercise and metaboreflex activation post-exercise muscle ischemia (PEMI). Relationships between endothelial function brachial artery flow-mediated dilation (FMD) and...

Fischer S, Maharaj A, Kang Y, Dillon K, Martinez M, Figueroa A
Int J Obes (Lond) . 2024 Jan; 48(11):1534-1541. PMID: 38228876
Background: Obesity (OB) is highly prevalent in females after menopause, especially visceral adipose tissue (VAT) accumulation which contributes to endothelial dysfunction. The endothelium assists in regulating blood flow (BF) during...

Dillon K, Kang Y, Maharaj A, Martinez M, Fischer S, Figueroa A
Br J Nutr . 2023 Sep; 131(3):474-481. PMID: 37664994
Postmenopausal women have augmented pressure wave responses to low-intensity isometric handgrip exercise (IHG) due to an overactive metaboreflex (postexercise muscle ischaemia, PEMI), contributing to increased aortic systolic blood pressure (SBP)....

Dellinger J, Figueroa A, Gonzales J
Microvasc Res . 2023 Jun; 149:104569. PMID: 37302468
We investigated the relationship between muscle microvascular responses during reactive hyperemia as assessed using near-infrared spectroscopy (NIRS) with changes in skeletal muscle oxygen saturation during exercise. Thirty young untrained adults...

Figueroa A, Maharaj A, Kang Y, Dillon K, Martinez M, Morita M, et al.
Nutrients . 2023 Apr; 15(7). PMID: 37049398
Postmenopausal women (PMW) may experience endothelial dysfunction associated with arginine (ARG) deficiency relative to asymmetric dimethylarginine (ADMA) caused by oxidative stress. Endothelial dysfunction contributes to increased blood pressure (BP) responsiveness...

Figueroa A, Wong A
Nutrients . 2023 Mar; 15(6). PMID: 36986220
The endothelium is crucial in controlling blood pressure and preventing cardiovascular diseases [...].

Kang Y, Dillon K, Martinez M, Maharaj A, Fischer S, Figueroa A
Nutrients . 2023 Jan; 15(1). PMID: 36615732
Hypertension is highly prevalent in postmenopausal women. Endothelial dysfunction is associated with hypertension and the age-related decreases in muscle mass and strength. L-citrulline supplementation (CIT) and slow velocity low-intensity resistance...

Maharaj A, Fischer S, Dillon K, Kang Y, Martinez M, Figueroa A
Nutrients . 2022 Oct; 14(20). PMID: 36297080
Aging and menopause are associated with decreased nitric oxide bioavailability due to reduced L-arginine (L-ARG) levels contributing to endothelial dysfunction (ED). ED precedes arterial stiffness and hypertension development, a major...
