Effects of polymorphisms in endothelial nitric oxide synthase and folate metabolizing genes on the concentration of serum nitrate, folate, and plasma…

2015

Abstract Objectives A number of studies have explored the effects of dietary nitrate on human health. Nitrate in the blood can be recycled to nitric oxide, which is an essential mediator involved in many important biochemical mechanisms. Nitric oxide is also formed in the body from l -arginine by nitric oxide synthase. The aim of this study was to investigate whether genetic polymorphisms in endothelial nitric oxide synthase (eNOS) and genes involved in folate metabolism affect the concentration of serum nitrate, serum folate, and plasma total homocysteine in healthy individuals after folic acid supplementation. Methods In a randomized double-blind, crossover study, participants were given …

Pulmonary function abnormalities in respiratory asymptomatic patients with inflammatory bowel disease

2002

BACKGROUND: There is evidence that pulmonary function abnormalities are present in patients with inflammatory bowel disease (IBD). The aim of this crossover study was to assess the frequency of pulmonary dysfunction in patients with IBD and to define the importance of possible confounding factors. METHODS: We investigated a total of 44 patients with Crohn's disease or ulcerative colitis and no pulmonary symptoms or a history of respiratory diseases by means of pulmonary function testing and chest X-ray. As controls we examined 44 healthy subjects matched for gender, age, and smoking status. RESULTS: A total of 21% of the subjects with ulcerative colitis and 20% with Crohn's disease showed a…

Effect of β-cryptoxanthin plus phytosterols on cardiovascular risk and bone turnover markers in post-menopausal women: a randomized crossover trial.

2014

Abstract Background and aim Post-menopausal women are at higher risk of cardiovascular disease and bone demineralization. Phytosterols (PS) may be used for hypercholesterolemia in some groups and β-cryptoxanthin (β-Cx) displays a unique anabolic effect on bone. Our aim was to assess the changes in cardiovascular and bone turnover markers from the oral intake of β-Cx and PS in post-menopausal women. Methods and results A randomized, double-blind, crossover study with β-Cx (0.75 mg/day) and PS (1.5 g/day), single and combined, was performed in 38 postmenopausal women. Diet was supplemented with 1 × 250 mL milk-based fruit drink/day for 4 weeks with a wash-out period of 4-weeks in between. Ser…

A double-blind, randomized, dose response study testing the pharmacological efficacy of synthetic porcine secretin

2000

Background: Biologically derived porcine secretin has been used as a diagnostic agent in clinical gastrointestinal practice for many years. Pure synthetic porcine secretin is now available for investigational clinical use. Aim: To compare the pharmacology of synthetic porcine secretin and biologically derived porcine secretin in healthy volunteers. Methods: Secretin stimulation tests were performed in 12 volunteer subjects in a double-blind, randomized, Latin square crossover design study comparing three doses of synthetic porcine secretin (0.05, 0.2, and 0.4 μg/kg) with a standard dose of biologically derived porcine secretin (1 CU/kg). Duodenal aspirates were analysed for total volume and…

Cartridge syringe vs computer controlled local anesthetic delivery system: Pain related behaviour over two sequential visits - a randomized controlle…

2015

Background: Local anesthetic injection is one of the most anxiety provoking procedure in dentistry. Knowledge about change in pain related behaviour during consecutive visits helps in and scheduling of treatment procedures and management of children in dental clinic. Aim: To compare the pain perception, behavioural response and the associated change in physiological parameters while receiving local anesthesia injection with cartridge syringe and computer controlled local anesthetic delivery system (CCLAD) over two consecutive visits. Material and Methods: In this randomized controlled cross over trial, 120 children aged 7 – 11 years were randomly divided into group A: receiving injections w…

Effects of a workplace physical exercise intervention on the intensity of low back symptoms in office workers: A cluster randomized controlled cross-…

2006

Objectives. The purpose of the study was to examine the effects of a workplace physical exercise intervention on the intensity of low back symptoms. Methods. The study was a cluster randomized controlled trial with department (n = 4) as the unit of randomization. The subjects were office workers [(n = 36), mean age 47.1 (SD 8.4) years] who self-reported low back symptoms, which restricted their daily activities during the last 12 months. Low back symptoms were measured using the Borg CR10 scale. The cross-over design consisted of one intervention period of light resistance training and guidance and no training and no guidance of 15 weeks duration. Statistical analyses were based on linear m…

PROSPECTIVE, RANDOMIZED, CROSSOVER COMPARISON OF SUBLINGUAL APOMORPHINE (3 mg) WITH ORAL SILDENAFIL (50 mg) FOR MALE ERECTILE DYSFUNCTION

2004

Abstract: Purpose: We established the efficacy and safety of sublingual apomorphine compared with oral sildenafil. in comparable groups of patients with erectile dysfunction (ED). Materials and Methods: This prospective, randomized, crossover study included 77 heterosexual men with ED of various etiologies and severities. A total of 62 men were randomized but only 34 were evaluable for efficacy and tolerability. The study started with a run-in period of 2 to 4 weeks. The first 4 weeks of treatment were followed by a washout period of 4 weeks, after which patients changed to the alternate treatment for an additional 4-week period. The sequence of the 2 treatments was established by a randomi…
