The new radioligand [H-3]-L 748,337 differentially labels human and rat beta(3)-adrenoceptors
2013
As no suitable radioligand exists for the detection of β3-adrenoceptors, we have explored the radioligand binding properties of a tritiated version of the selective β3-adrenoceptor antagonist L 748,337. Kinetic and equilibrium saturation and competition binding experiments were performed with [(3)H]-L 748,337 on membrane fractions of HEK and CHO cells stably transfected with human and rat β-adrenoceptor subtypes. Based on both association/dissociation kinetic and equilibrium saturation binding studies in transfected HEK cells, [(3)H]-L 748,337 exhibited an affinity of approximately 2 nM for human β3-adrenoceptors. Competition studies with agonists and subtype-selective antagonists validated…
Inhibition of Trypanosoma cruzi growth by medical plant extracts
2002
This study describes the screening of extracts obtained from 18 plants and two fungi used in the Chinese and Mediterranean traditional medicines on epimastigote forms of Trypanosoma cruzi. The extracts were tested against epimastigote of T. cruzi Bra C15C2 clone in vitro at 27 degrees C and at a concentration of 250 microg/ml in axenic culture. Angelica dahurica, A. pubescens, A. sinensis, Astragalus membranaceus, Coptis chinensis, Haplophyllum hispanicum, Phellodendron amurense, Poria cocos, Ranunculus sceleratus and Scutellaria baicalensis showed significant effects against the parasite with a percentage of growth inhibition between 20 and 100%. C. chinensis and R. sceleratus showed the g…
Burning mouth syndrome: is acupuncture a therapeutic possibility?
2010
Burning mouth syndrome is a chronic pathology of unknown ethiopathogenesis. The aim of this study was to evaluate whether acupuncture can produce a reduction of the burning sensation by influencing the oral microcirculation. METHODS: Thirty patients (10 male and 20 female; mean age +/- SD = 65.4 +/- 2.17) and 30 healthy subjects (10 male and 20 female; mean age +/- SD = 62.06 +/- 6.72) were recruited for the study. The patients were treated with acupunctural techniques based on traditional Chinese medicine. Microcirculation was observed in vivo using videocapillaroscopy at three different times: t(0)) in the absence of acupuncture; t(1)) 1 minute after the insertion of the needles; and t(2)…
Overweight and obesity are associated with cardiac adverse structure remodeling in Chinese elderly with hypertension
2019
AbstractThere is limited information on the association of overweight and obesity with cardiac remodeling in elderly population. Therefore, we investigated whether overweight and obesity are associated with cardiac geometric structures and function in Chinese elderly. A total of 1183 hospitalized patients (aged 65–99 years) with primary hypertension were collected retrospectively in a cross-sectional study, and divided into underweight, normal weight, overweight and obesity patient groups according to their body mass index (BMI). Cardiac echocardiographic parameters were compared between the groups. BMI was 17.2 ± 1.2, 21.4 ± 1.2, 25.1 ± 1.2, 30.2 ± 2.6 kg/m2 in underweight, normal weight, …
COMPETITIVENESS OF LATVIAN FIRMS IN CHINA
2012
The results of the firms’ performance are one of the key aspects in the research of competitiveness. The competitiveness of firms is a concept that involves many aspects of measurement. There are many models that can be used to assess the international competitiveness of firms, including the competitiveness of foreign firms in the Chinese market. The opportunities of Latvian firms to enter China market and the capabilities of Latvian firms to compete in China have not so far been sufficiently studied. In 2010 the export volume of Latvian firms to China was 25 million EUR and more than half of it was export of raw materials. The model of SME competitiveness is used to research the competitiv…
Supply chain – marketing integration: How do European SMEs go to China via the New Silk Road
2018
Purpose The purpose of this paper is to discuss China’s New Silk Road initiative as an opportunity for European small and medium-sized enterprises (SMEs) to export to Chinese market. It offers research propositions on redefining the business process of European SMEs and Chinese importers in light of the initiative. Design/methodology/approach SMEs’ export barriers, particularly in SCM and marketing, are identified through literature review. Then they are discussed in accordance with the measures that New Silk Road proposed. Findings Logistic infrastructure development under the New Silk Road significantly lowers the supply chain barrier. Marketing remains a challenge for European SMEs to e…
Optimization of Cell Growth on Bacterial Cellulose by Adsorption of Collagen and Poly-L-Lysine
2015
Poly-L-lysine and collagen were separately added to bacterial cellulose (BC) nanofibers. The ionic surface charge had been previously modified in order to promote the adsorption of poly-L-lysine and collagen. Cell adhesion of Chinese hamster ovary (CHO) cells on BC surfaces was confirmed by removing unattached cells from the BC substrates. Cell viability was calculated and it was determined that both poly-L-lysine-BC and collagen-BC substrates are viable for cell growth. The results showed that the cell viability in poly-L-lysine modified BC substrate is similar to the one observed in polystyrene tissue culture plates.
Ricerca educativa in ambienti multiculturali con allievi cinesi: la lingua scritta come ponte per un avvio informale al pensiero algebrico-relazionale
2017
Il contributo, evidenziando l’attuale proble- matica didattica relativa alla multiculturalità nel panorama scolastico nazionale, discute alcuni aspetti chiave della cultura cinese, uti- li ad interpretare il perché di particolari competenze algebriche, evidenziate negli allievi di area confuciana dagli insegnanti di tutti i gradi scolastici, coerenti con le valuta- zioni internazionali PISA e TIMMS. Con questo scopo, il lavoro propone nello specifico una riflessione epistemologica del rapporto tra lingua scritta cinese e avvia- mento informale al pensiero algebrico-rela- zionale e discute i dati sperimentali (di tipo implicativo) di una ricerca-azione condotta in classi di Scuola Primaria c…
Cultural diversity: how can it increases the complexity of teaching mathematics in multicultural class? The case of Chinese students
2015
The paper, examining the increasing presence of different culture students in Italy, discusses the didactical problematic of multiculturalism at School. In particular a possible “comparison” between East (China, Korea and Japan) and West mathematical epistemology is presented through a historical and linguistic cultural approaches. Some evidences of analogies and differences between the cognitive styles of Chinese and Italian learners in mathematics are presented as examples to show the complexity of teaching/learning mathematics in multicultural classroom
