Influence of low temperature on bronchodilatation induced by terbutaline administered by metered dose or dry powder inhalers in asthmatics.

2000

Low temperatures may affect dose delivery efficacy and clinical effectiveness of medication aerosols. In this study we examine the effect of cold ambient temperature on the bronchodilatation produced by terbutaline delivered from a chlorofluorocarbon pressurized metered dose inhaler (pMDI) compared to a multi-dose dry powder inhaler (DPI). Fourteen stable asthmatics were studied on two consecutive days. On day 1, after measuring FEV1 at room temperature (22 degrees C), each patient was randomized to receive 500 microg of terbutaline delivered from pMDI or DPI stored for 24 h at 22 degrees C with FEV1 recorded 20 min post-dose; then, patients were placed in a chamber at -10 degrees C, and af…

Sources of human plasma cyclic AMP. Examinations before and after beta 2 adrenergic stimulation.

1981

Plasma cyclic AMP was measured in different vessels in seventeen volunteers before and after stimulation with terbutaline. Differences between arterial blood and blood from the hepatic vein, right ventricle, inferior vena cava and a cubital vein could not be demonstrated. Only in the renal vein was the concentration of cyclic AMP decreased. Our results indicate that cyclic AMP is not generated from any specific isolated organ and that changes in cyclic AMP after subcutaneous injection of terbutaline reflect a general influence of this drug.

Progesterone increases basal 3',5'-cyclic adenosine monophosphate formation and down-regulates the agonist-induced inositol phosphates generation in …

1992

Whether the placenta is a target tissue for estrogens and progesterone, and their putative mechanism of action, is still a controversial question in the literature. The effect of progesterone and estradiol on 3′,5′-cyclic adenosine monophosphate (cAMP) and inositol phosphates generation in human term placenta was investigated. Placental explants were incubated in vitro for up to 48 h in the absence and in the presence of estradiol, progesterone or both steroids (0.1 μmol/l final concentration in all cases), and were stimulated with terbutaline, a β-adrenergic agonist, (0.1 mmol/l) or angiotensin II(1 μmol/l), The cAMP content was measured by a competitive protein binding assay, and the gene…

Regular versus as-needed budesonide and formoterol combination treatment for moderate asthma: A non-inferiority, randomised, double-blind clinical tr…

2015

Summary Background Treatment guidelines for patients with moderate persistent asthma recommend regular therapy with a combination of an inhaled corticosteroid and a longacting β 2 agonist plus as-needed rapid-acting bronchodilators. We investigated whether symptom-driven budesonide and formoterol combination therapy administered as needed would be as effective as regular treatment with this combination plus as-needed symptom-driven terbutaline for patients with moderate asthma. Methods In this non-inferiority randomised clinical trial, we recruited adult patients (18–65 years of age) with stable moderate persistent asthma, according to 2006 Global Initiative for Asthma guidelines. Patients …

Effect of budesonide/formoterol maintenance and reliever therapy on asthma exacerbations

2007

This randomised, double-blind, 6-month study compared budesonide/formoterol for maintenance and relief with salmeterol/fluticasone and a fixed maintenance dose of budesonide/formoterol, both with terbutaline for relief. Following a 2-week run-in, 3335 symptomatic adults and adolescents (mean FEV1 73% predicted, mean inhaled corticosteroid dose 745 μg/day) received budesonide/formoterol 160/4.5 μg one inhalation bid plus additional inhalations as needed, salmeterol/fluticasone 25/125 μg two inhalations bid plus as-needed terbutaline or budesonide/formoterol 320/9 μg one inhalation bid plus as-needed terbutaline. Budesonide/formoterol for maintenance and relief prolonged the time to first sev…

Tannin analysis of chestnut bark samples (Castanea sativa Mill.) by HPLC-DAD-MS.

2014

In the present investigation, an HPLC-DAD/ESI-MS method for the complete analysis of tannins and other phenolic compounds of different commercial chestnut bark samples was developed. A total of seven compounds (vescalin, castalin, gallic acid, vescalagin, 1-O-galloyl castalagin, castalagin and ellagic acid) were separated and quantified, being 1-O-galloyl castalagin tentatively identified and found for the first time in chestnut bark samples. Thus, this method provided information regarding the composition and quality of chestnut bark samples, which is required since these samples are commercialised due to their biochemical properties as ingredients of food supplements.

Characterization of the Epithelial Permeation Enhancing Effect of Basic Butylated Methacrylate Copolymer—In Vitro Studies

2008

Membrane destabilizing properties and increased efflux of doxorubicin from liposomes caused by basic butylated methacrylate copolymer (BBMC), better known under its commercial trade name EUDRAGIT E, have been described in the scientific literature. Here, we investigated the effect of BBMC on suspended and filter-grown Caco2 cells with respect to apical-to-basal transport and membrane permeabilization using transport assays, trypan blue exclusion assay, measurements of transepithelial electrical resistance (TEER), confocal laser scanning microscopy, and transmission electron microscopy. The effect of inhibiting protein phosphatase 2A (PP2A) by okadaic acid was investigated by measuring TEER,…

The Translation Scene in Latvia (Latvian SSR) during the Stalinist Years

2018

[full article, abstract in English; abstract in Lithuanian] In this paper the author continues to explore the translation scene in 20th century Latvia (Veisbergs 2016a). The period under discussion covers 1945–1953, the years of Stalin’s rule after WWII until his death in 1953. The translation situation is described by discussing nationalisation and centralisation of publishers, book liquidation, censorship, ideologisation and politicisation, russification, Latvian émigré translations and other aspects of importance in an attempt to present the translation scene of the period from different angles. At the end of the article an extensive list of references is provided that can serve as an in…

Metalinguistic Development in First-Language Acquisition

1997

At a very early age, the child is able to manipulate language appropriately, both in its comprehension and its production. Later comes the ability to reflect upon and deliberately control its use. The emergence of these metalinguistic abilities must be distinguished from that of ordinary verbal communication. The key questions concerning this topic are: What is metalinguistics? What knowledge do metalinguistic abilities require? Are they conscious activities? And how do they develop? (also see the review by Tunmer in Volume 2 and by Nicholson in this volume.)
