BACKGROUND Absence of the left circumflex artery (LCX) is an extremely rare congenital anomaly of the coronary circulation. While some coronary circulation anomalies are associated with significant complications, including sudden cardiac death and premature atherosclerosis, absence of the LCX is largely considered benign, though it has been associated with(More)
OBJECTIVES Previous studies indicated that oral estrogen increased C-reactive protein by a first-pass hepatic effect. In this study, we determine whether the route of estrogen administration influences serum amyloid A (SAA), another acute-phase protein produced by the liver, and the SAA content of the high-density lipoprotein (HDL-SAA) in postmenopausal(More)
The peroxisome proliferator-activated receptors (PPARs) are nuclear fatty acid receptors, which contain a type II zinc finger DNA binding motif and a hydrophobic ligand binding pocket. These receptors are thought to play an important role in metabolic diseases such as obesity, insulin resistance, and coronary artery disease. Three subtypes of PPAR receptors(More)
During static exercise, metabolites accumulate in the muscle interstitium where they stimulate chemosensitive afferent nerves that reflexly increase efferent muscle sympathetic nerve activity (MSNA) and blood pressure. In experimental animals, lactic acid potently stimulates the muscle metaboreflex, but its role in humans is more controversial. To determine(More)
Sodium glucose co-transporter 2 (SGLT2) inhibitors are a new class of anti-diabetic medications. Canagliflozin was the first drug approved in this group in 2013 and subsequently dapagliflozin was approved in January 2014 and empagliflozin was approved in August 2014. Preclinical studies have demonstrated safety, tolerability, and efficacy in terms of(More)
Previous studies suggest beta-adrenergic receptor (β-AR) antagonists (β-blockers) decrease breast cancer progression, tumor metastasis, and patient mortality; however the mechanism for this is unknown. Immunohistochemical analysis of normal and malignant breast tissue revealed overexpression of β1-AR and β3-AR in breast cancer. A retrospective(More)
PATIENT Male, 29 FINAL DIAGNOSIS: Myopericarditis Symptoms: Chest pain Medication: Ibuprofen Clinical Procedure: - Specialty: Cardiology. OBJECTIVE Unusual clinical course. BACKGROUND Cannabis is the most commonly used illegal substance worldwide and its consumption portends significant side effects. Nowadays, in order to increase its psychotropic(More)
A compact femtosecond dual-oscillator pump-probe setup with 48 MHz-repetition rate, relying on asynchronous optical sampling, is presented. The relative timing jitter between both lasers over the whole pump-probe delay range is of the order of or lower than 500 fs. We demonstrate that both a picosecond temporal resolution and a 48 MHz spectral resolution(More)
Surface enhanced Raman spectroscopy combined with transposed Orthogonal Partial Least Squares (T-OPLS) was shown to produce chemical images of the natural antibacterial surface-active compound 1,1,3,3-tetrabromo-2-heptanone (TBH) on Bonnemaisonia hamifera. The use of gold colloids functionalised with the internal standard 4-mercapto-benzonitrile (MBN) made(More)
Obesity is thought to lead to sympathetic overactivity as a compensatory adjustment to weight gain. However, most of the experimental support for the hypothesis has been derived from white cohorts. Our previous study in blacks indicated that sympathetic nerve activity (SNA) is closely correlated with body mass index only in women, whereas, in black men, SNA(More)
