The effect of two low doses of aspirin on whole blood thromboxane and prostacyclin generation in healthy subjects
1983
SummaryThe effects of two low doses of aspirin (20 mg and 100 mg) on prostacyclin and thromboxane formation during whole blood clotting were studied in 8 healthy volunteers.A single 100 mg aspirin dose caused more than 90% reduction of both serum TXB2 and 6-keto-PGF1α; a single 20 mg dose of aspirin inhibited serum TXB2 more than 6-keto-PGF1α but effects on these two products could not be completely dissociated.However, the effect of a single 20 mg aspirin dose on serum TXB2, was of much longer duration than its inhibitory effect on PGI2 synthesis during whole blood clotting.
Prevalence of dyslipidemia and associated risk factors in Turkish adults.
2013
Background and Objectives Dyslipidemia is a modifiable major risk factor for coronary heart disease. The objective of this study was to determine the prevalence of dyslipidemia among Turkish adults and its associations with other cardiovascular risk factors. Methods This study included 4309 people ages 20 to 83 years old from 7 provinces of Turkey. People from the city centers, districts, and villages were selected by a stratified sampling method. Weight, height, and waist and hip circumferences were measured. Blood samples were obtained to determine glucose, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides …
The effects of whey protein with or without carbohydrates on resistance training adaptations.
2015
Background Nutrition intake in the context of a resistance training (RT) bout may affect body composition and muscle strength. However, the individual and combined effects of whey protein and carbohydrates on long-term resistance training adaptations are poorly understood. Methods A four-week preparatory RT period was conducted in previously untrained males to standardize the training background of the subjects. Thereafter, the subjects were randomized into three groups: 30 g of whey proteins (n = 22), isocaloric carbohydrates (maltodextrin, n = 21), or protein + carbohydrates (n = 25). Within these groups, the subjects were further randomized into two whole-body 12-week RT regimens aiming …
Intra-renal hemodynamics and carotid intima-media thickness in the metabolic syndrome.
2009
Aims: Metabolic syndrome (MetS) is associated with increased cardiovascular risk. We hypothesize that early vascular changes are already present at the time of diagnosis of MetS. The relationship of different measures of early vascular impairment with body fat distribution and the natural progression of MetS was examined in newly diagnosed subjects non-pharmacologically treated. Methods: 246 consecutively enrolled subjects were categorized according to the presence of MetS and type 2 diabetes (T2D). Intra-renal Doppler flow was used to ascertain resistive (RI) and pulsatility (PI) indices as markers of vascular resistance. Carotid intima-media thick- ness (IMT), cutis-rectis (CR) and rectis…
Prognostic factors of macrophage activation syndrome, at the time of diagnosis, in adult patients affected by autoimmune disease: Analysis of 41 case…
2016
Macrophage activation syndrome (MAS) is a rare, life-threatening disease in which early diagnosis and aggressive therapeutic strategy may improve the outcome. Due to its rarity, epidemiologic data are still lacking. Hyperferritinemia is frequently associated with MAS and might modulate the cytokine storm, which is involved in the development of multiple organ failure. In this paper, we investigated clinical data, treatments, and outcome of a homogeneous cohort of 41 adult MAS patients, complicating autoimmune rheumatic diseases. MAS-related death occurred in 17 patients (42.5%) during the follow-up, and older age and increased serum ferritin levels, at the time of diagnosis, were significan…
Fatal hypersensitivity reaction to an oral spray of flurbiprofen: a case report
2013
Summary What is known and objective Safety of the anti-inflammatory drug flurbiprofen is comparable with that of other non-steroidal anti-inflammatory drugs of the propionic acid class, which are commonly associated with gastrointestinal and renal side effects. Here we report a case of a fatal hypersensitivity reaction to an oral spray of flurbiprofen taken for sore throat. Case summary A 29-year-old man came to the emergency care unit reporting sore throat with an intense burning sensation associated with fever. Pharyngotonsillitis was diagnosed, and local treatment with oral flurbiprofen spray was prescribed. Immediately after using the spray, the patient experienced a severe reaction cha…
Plasma and fibroblasts of Tangier disease patients are disturbed in transferring phospholipids onto apolipoprotein A-I
1998
Plasmas of patients with Tangier disease (TD) lack lipid-rich α-HDL which, in normal plasma, constitutes the majority of high density lipoprotein (HDL). Residual amounts of apolipoprotein (apo)A-I in TD plasma occur as lipid-poor or even lipid-free preβ-HDL. By contrast to normal plasma, TD plasma does not convert preβ-HDL into α-HDL. Moreover, fibroblasts of TD patients were found to be defective in secreting cholesterol or phospholipids in the presence of lipid-free apoA-I. We have therefore hypothesized that both defective conversion of preβ-HDL into α-HDL and defective lipid efflux from TD cells onto lipid-free apoA-I result from a disturbance in phospholipid transfer occurring in both …
Effect of continuous oestradiol-medroxyprogesterone administration on plasma lipids and lipoproteins
1991
Plasma lipids and lipoproteins were measured in 21 post-menopausal women after 4 and 8 months of continuous treatment with an orally administered combination of oestradiol and medroxyprogesterone acetate. The mean concentrations of cholesterol and low-density-lipoprotein (LDL) cholesterol were reduced by 12% (P less than 0.001) and 11% (P less than 0.01), respectively, after 4 months of treatment and by 9% (P less than 0.05) and 12% (P less than 0.05) after 8 months. The mean level of high-density-lipoprotein (HDL) cholesterol showed an initial fall of 5% (P less than 0.05) after 4 months and then increased by 13% (P less than 0.05) after 8 months of treatment. The plasma triglycerides leve…
Soothing the seizures of children.
2008
Endocannabinoids are versatile molecules, regulating a variety of functions in the body. Daniele Piomelli explores how recent clinical trials testing rimonabant, an inhibitor of endocannabinoid signaling, for weight loss emerged from studies of individuals with schizophrenia; such trials have spurred basic research into how endocannabinoids affect both energy use and mood. Beat Lutz and Krisztina Monory examine how rimonabant might prove useful for preventing the development of adult epilepsy in response to fever-induced seizures in infants and young children.
Milder forms of atherogenic dyslipidemia in ovulatory versus anovulatory polycystic ovary syndrome phenotype
2017
BACKGROUND: Dyslipidemia is common in women with polycystic ovary syndrome (PCOS) but its prevalence in different PCOS phenotypes is still largely unknown. METHODS: We measured plasma lipids and lipoproteins in 35 anovulatory PCOS (age: 25 ± 6 years, BMI: 28 ± 6 kg/m2), 15 ovulatory PCOS (age: 30 ± 6 years, BMI: 25 ± 3 kg/m2) and 27 healthy women (controls) age- and BMI-matched with ovulatory PCOS. PCOS was diagnosed by the presence of clinical or biologic hyperandrogenism associated with chronic anovulation and/or polycystic ovaries at ultrasound. In women with normal menses chronic anovulation was indicated by low serum progesterone levels (<9.54 nmol/l) during midluteal phase (days 21…
