Effects of gemfibrozil on insulin sensitivity and on haemostatic variables in hypertriglyceridemic patients.

2000

In order to assess the efficacy of gemfibrozil on lipid and haemostatic parameters in patients with plurimetabolic syndrome, a multicenter double-blind placebo controlled, parallel study was carried out in 56 patients with primary hypertriglyceridemia and glucose intolerance. These patients had elevated PAI activity and antigen and t-PA antigen levels at rest and after venous occlusion. Gemfibrozil reduced plasma triglyceride levels (P0.001), whereas it increased free fatty acids (P0.05) and high density lipoprotein cholesterol levels (P0.05). In those patients reaching normalization of plasma triglyceride levels (triglyceride reductionor =50%) (n=15), insulin levels (P0.05) as well as the …

Application of tRNS to improve multiple sclerosis fatigue: a pilot, single-blind, sham-controlled study

2019

We evaluated the effects of transcranial random noise stimulation (tRNS) on fatigue in 17 subjects with relapsing–remitting multiple sclerosis with low physical disability. Two different patient groups underwent real or sham stimulation for 10 days, targeting the primary motor cortex of the dominant side or contralateral to the most compromised limb. In the ‘real group’, beneficial effects were observed using the Modified Fatigue Impact Scale (p = 0.04; physical subscale: p = 0.03), the subscales ‘change in health’ (p = 0.006) and ‘role limitations due to physical problems’ (p = 0.001) of the Multiple Sclerosis Quality of Life-54, and by assessing the patient impression of perceived fatigue…

Gemfibrozil reduces small low-density lipoprotein more in normolipemic subjects classified as low-density lipoprotein pattern B compared with pattern…

2005

We tested the hypothesis that gemfibrozil has a differential effect on low-density lipoprotein (LDL) and high-density lipoprotein (HDL) subclass distributions and postprandial lipemia that is different in subjects classified as having LDL subclass pattern A or LDL pattern B who do not have a classic lipid disorder. Forty-three normolipemic subjects were randomized to gemfibrozil (1,200 mg/day) or placebo for 12 weeks. Lipids and lipoproteins were determined by enzymatic methods. The mass concentrations of lipoproteins in plasma were determined by analytic ultracentrifugation and included the S(f) intervals: 20 to 400 (very LDL), 12 to 20 (intermediate-density lipoprotein), 0 to 12 (LDL), an…

Novel LMF1 nonsense mutation in a patient with severe hypertriglyceridemia

2009

Context: Lipase maturation factor 1 (LMF1) gene is a novel candidate gene in severe hypertriglyceridemia. Lmf1 is involved in the maturation of lipoprotein lipase (LPL) and hepatic lipase in endoplasmic reticulum. To date only one patient with severe hypertriglyceridemia and related disorders was found to be homozygous for a nonsense mutation in LMF1 gene (Y439X).Objective: The objective of the study was to investigate LMF1 gene in hypertriglyceridemic patients in whom mutations in LPL, APOC2, and APOA5 genes had been excluded.Results: The resequencing of LMF1 gene led to the discovery of a novel homozygous nonsense mutation in one patient with severe hypertriglyceridemia and recurrent epis…

Habitat Preferences of Breeding Amphibians in Eastern Spain

2018

The aim of this research was to determine the reproductive habitat preferences of several species of amphibians in eastern Spain. We recorded amphibia presence/absence and measured biotic and abiotic variables at 67 ponds in a 43.5 km2 area representing a wide variety of aquatic ecosystems, such as temporary and semipermanent cisterns, drinking troughs, and natural and artificial ponds, all of various sizes and depths. We used this information to predict occupancy using Generalized Linear Models. We built models for the Iberian Ribbed Newt (Pleurodeles waltl), Iberian Green Frog (Pelophylax perezi), Common Midwife Toad (Alytes obstetricans), Natterjack Toad (Epidalea calamita), and Mediterr…

Cation binding resorcinarene bis-crowns: the effect of lower rim alkyl chain length on crystal packing and solid lipid nanoparticles

2012

A group of seven resorcinarene bis-crown ethers (CNBC5) with two polyether bridges at the upper rim and either propyl, butyl, pentyl, heptyl, nonyl, decyl or undecyl groups at the lower rim were synthesized and their binding properties with Cs+ were investigated by NMR titration. The bis-crowns form 1:2 complexes with Cs+ with binding constants of logK 4–5. Crystal structures of bis-crowns and their Cs+ and K+ complexes were studied and different packing motifs were found depending on the alkyl chain length. Short ethyl, propyl and butyl alkyl chains gave a layer or pillar packing where the polar and non-polar regions cannot be distinguished, whereas longer pentyl and decyl chains formed bi…

Do metric fluctuations affect the Higgs dynamics during inflation?

2017

We show that the dynamics of the Higgs field during inflation is not affected by metric fluctuations if the Higgs is an energetically subdominant light spectator. For Standard Model parameters we find that couplings between Higgs and metric fluctuations are suppressed by $\mathcal{O}(10^{-7})$. They are negligible compared to both pure Higgs terms in the effective potential and the unavoidable non-minimal Higgs coupling to background scalar curvature. The question of the electroweak vacuum instability during high energy scale inflation can therefore be studied consistently using the Jordan frame action in a Friedmann--Lema\^itre--Robertson--Walker metric, where the Higgs-curvature coupling …
