Metabolic reprogramming by Acly inhibition using SB-204990 alters glucoregulation and modulates molecular mechanisms associated with aging.

ATP-citrate lyase is a central integrator of cellular metabolism in the interface of protein, carbohydrate, and lipid metabolism. The physiological consequences as well as the molecular mechanisms orchestrating the response to long-term pharmacologically induced Acly inhibition are unknown. We report here that the Acly inhibitor SB-204990 improves metabolic health and physical strength in wild-type mice when fed with a high-fat diet, while in mice fed with healthy diet results in metabolic imbalance and moderated insulin resistance.

Time domain measurement of the vascular and myocardial branches of the baroreflex: A study in physically active versus sedentary individuals.

This study tests the spontaneous sequence method for the evaluation of the cardiac, vasomotor, and myocardial branches of the baroreflex. Systolic blood pressure (SBP), interbeat interval (IBI), stroke volume (SV), preejection period (PEP), and total peripheral resistance (TPR) were continuously recorded in 33 physically active and 25 sedentary participants at rest and during a mental arithmetic task. Sequences of spontaneous covariation between SBP and IBI (for the cardiac branch), SV and PEP (for the myocardial branch), and TPR (for the vasomotor branch) were located.

[Development and validation of the Childhood Perfectionism Inventory (I.P.I.)].

There are a few studies linking children's perfectionism with diverse internalized or externalized disorders. Likewise, in Spanish, there is no scale that measures the diverse aspects that comprise it. This paper presents the Children's Perfectionism Inventory (IPI).

Relationships between baroreceptor cardiac reflex sensitivity and cognitive performance: modulations by gender and blood pressure.

This study aimed at replicating and extending previous results on the association between baroreceptor reflex sensitivity (BRS) and cognitive performance. Thirty men and 31 women performed an arithmetic task. After adjusting for numerical aptitude and effort, no predictors of performance were found in men.

Aberrances in autonomic cardiovascular regulation in fibromyalgia syndrome and their relevance for clinical pain reports.

Objective: To investigate autonomic cardiovascular regulation in fibromyalgia syndrome (FMS).

Methods: In 35 patients and 29 healthy controls, electrocardiography, impedance cardiography, and finger continuous blood pressure measurements were conducted. Assessed parameters comprised blood pressure, R-R interval (RRI), heart rate variability, baroreflex sensitivity (BRS), stroke volume, and left ventricular ejection time (LVET).
