2009
KRAEMER, W. J., D. L. HATFIELD, J. S. VOLEK, M. S. FRAGALA, J. L. VINGREN, J. M. ANDERSON, B. A. SPIERING, G. A. THOMAS, J. Y. HO, E. E. QUANN, M. IZQUIERDO, K. HAKKINEN, and C. M. MARESH. Effects of Amino Acids Supplement on Physiological Adaptations to Resistance Training. Med. Sci. Sports Exerc., Vol. 41, No. 5, pp. 1111-1121, 2009. Introduction: Previous research has demonstrated that ingestion of essential amino acids and their metabolites induce anabolic effects with the potential to augment gains in lean body mass and strength after resistance exercise training. Purpose: The purpose of the present study was to examine the effects of an essential amino acid-based formula (Muscle Armor…
Electrophysiological Investigations of Shape and Reproducibility of Oropharyngeal Swallowing: Interaction with Bolus Volume and Age
2015
Electrophysiological assessment provides valuable information on physiological and pathophysiological characteristics of human swallowing. Here, new electrophysiological measures for the evaluation of oropharyngeal swallowing were assessed: (1) the activation pattern of the submental/suprahyoid EMG activity (SHEMG); (2) the reproducibility of the oral and pharyngeal phases of swallowing, by calculating the similarity index (SI) of the SHEMG (SI-SHEMG) and of the laryngeal-pharyngeal mechanogram (SI-LPM) during repeated swallows; and (3) kinesiological measures related to the LPM. An electrophysiological-mechanical method for measuring the activation pattern of the SHEMG, the SI-SHEMG, and t…
Acute effects of coffee on QT interval in healthy subjects
2011
Abstract The coronary endothelial function is recognized to have an important role in the physiology of the diastolic ventricular relaxation, a phase of the heart cycle that influences the electrocardiographic QT interval. Endothelial function is investigated in vivo by flow mediated dilation (FMD) in the brachial artery and has proven to be a strong predictor of both coronary endothelial function and cardiovascular events. It has been reported that coffee acutely induces FMD changes. In particular, the brachial artery FMD seems to decrease after caffeinated coffee (CC) and to increase after decaffeinated coffee (DC) ingestion. Since the cardiovascular effects of coffee are still a debated …
Dose-dependent effects of decaffeinated coffee on endothelial function in healthy subjects
2009
ackground/Objectives: Coffee is known to contain antioxidant substances whose effects may be blunted because of caffeine that may unfavorably affect the cardiovascular system. This study was designed to investigate the acute dose-dependent effects of decaffeinated coffee (DC) on endothelial function measured by the brachial artery flow-mediated dilation (FMD). Subjects/Methods: A total of 15 (8 men and 7 women) healthy nonobese subjects underwent a single-blind, crossover study. Subjects ingested one and two cups of decaffeinated Italian espresso coffee in random order at 5- to 7-day intervals. Results: In the hour following the ingestion of two cups of DC, FMD increased (mean±s.e.m.): 0 mi…
The Applicability of a Checklist for the Diagnosis and Treatment of Exocrine Pancreatic Insufficiency: Results of the Italian Exocrine Pancreatic Ins…
2020
Objective To evaluate a rapid checklist capable of identifying exocrine pancreatic insufficiency in outpatients. Methods Prospective observational study of a multicenter cohort. Results One hundred and two patients were enrolled; 61.8% of the patients had medically-treated benign or malignant pancreatic disease, and 38.2% had a pancreatic resection. Visual examination of the feces was evaluated in 84 patients and it was related to steatorrhea in 51 patients (50.0%). Receiver operating characteristic curves were evaluated for each symptom or clinical sign and four of them (ie, increase in daily bowel movements, number of bowel movements, fatty stools, >10% weight loss) had a satisfactory …
Gastric emptying of indigestible tablets in relation to composition and time of ingestion of meals studied by metal detector.
1991
Enteric-coated tablets leave the stomach mainly during the interdigestive phase. Composition as well as time of ingestion of meals may influence their gastric emptying considerably. In 12 normal volunteers gastric emptying of a plastic tablet with a metal core was followed by a metal detector in relation to different compositions and various times of ingestion of meals. With an empty stomach and after ingestion of 250 ml water, the mean time for gastric emptying of the tablet was 38 +/- 11 min (mean +/- SEM) and 38 +/- 8 min. Two hundred fifty milliliters of milk (652 kJ) and a formula diet (1000 kJ) delayed gastric emptying time to 128 +/- 14 and 152 +/- 6 min, respectively (P less than 0.…
Retrospective analysis of management of ingested foreign bodies and food impactions in emergency endoscopic setting in adults.
2016
Background: Ingestion of foreign bodies and food impaction represent the second most common endoscopic emergency after bleeding. The aim of this paper is to report the management and the outcomes in 67 patients admitted for suspected ingestion of foreign body between December 2012 and December 2014. Methods: This retrospective study was conducted at Palermo University Hospitals, Italy, over a 2-year period. We reviewed patients’ database (age, sex, type of foreign body and its anatomical location, treatments, and outcomes as complications, success rates, and mortalities). Results: Foreign bodies were found in all of our 67 patients. Almost all were found in the stomach and lower esophagus (…
Protein Ingestion Prior to Strength Exercise Affects Blood Hormones and Metabolism
2005
HULMI, J. J., J. S. VOLEK, H. SELANNE, and A. A. MERO. Protein Ingestion Prior to Strength Exercise Affects Blood Hormones and Metabolism. Med. Sci. Sports Exerc., Vol. 37, No. 11, pp. 1990 -1997, 2005. Purpose: The effects of protein consumption before strength training session on blood hormones, energy metabolites, RER, and excess postexercise oxygen consumption (EPOC) were examined. Methods: Ten resistance-trained young men consumed either a 25 g of whey and caseinate proteins (PROT) or a noncaloric placebo (P) in a liquid form 30 min before a heavy strength training session (STS) in a crossover design separated by at least 7 d. STS lasted 50 min and included 5 1 RM squats, 3 10 RM squat…
Emotional Self-Regulation Therapy: A New and Efficacious Treatment for Smoking
1997
Abstract We describe emotional self-regulation therapy, a recently-developed suggestion technique for the treatment of smoking, and present data attesting to its efficacy. Of the 38 individuals who completed treatment, 82% (47% of the initial sample) stopped smoking altogether and 13% (8%of the initial sample) reduced their smoking. A follow-up at 6 months showed that 66% (38% of the initial sample) of those who had completed the treatment remained abstinent and reported minimal withdrawal symptoms or weight gain. In a no-treatment comparison group, only 8% reduced their smoking or became abstinent.
TRANSCRANIAL DIRECT CURRENT STIMULATION ENHANCES SUCKING OF A LIQUID BOLUS IN HEALTHY HUMANS
2014
Abstract Background Transcranial direct current stimulation (tDCS) is a non-invasive technique used for modulating cortical excitability in vivo in humans. Here we evaluated the effect of tDCS on behavioral and electrophysiological aspects of physiological sucking and swallowing. Methods Twelve healthy subjects underwent three tDCS sessions (anodal, cathodal and sham stimulation) on separate days in a double-blind randomized order. The active electrode was placed over the right swallowing motor cortex. Repeated sucking and swallowing acts were performed at baseline and at 15 and 60 min after each tDCS session and the mean liquid bolus volume ingested at each time point was measured. We also…
