Gag reflex control through acupuncture: a case series.

2014

Background Many patients avoid dental appointments because of severe gagging when they have work performed, such as taking impressions. There are several methods known to alleviate gagging, and some studies have suggested that acupuncture may be effective in reducing gag reflex. The aim of the present study therefore was to evaluate whether acupuncture can produce a reduction of the gag reflex. Methods A total of 20 patients, aged between 19 and 80 years, with history of gag reflex on taking dental impressions, were recruited. All patients fulfilling the inclusion criteria had an upper and lower dental alginate impression taken without acupuncture, and a second upper and lower alginate impr…

Processi cognitivi e soluzioni di problemi matematici con studenti italiani e cinesi

2012

To compare cognitive processes adopted by students with different cultures in solving mathematical problems we have to focus on the Math epistemology through a cultural analysis concerning the fundamental elements of the students different cultural traditions and the philosophical, logic and linguistic bases subtended to the mathematical thought and its historical evolution. The paper describes this theoretical framework, emphasizing a possible comparison between different cognitive styles and mathematical problem solutions in the context of arithmetic and Algebraic thought of Italian and Chinese students in multicultural classes.

Chemical Constituents and Pharmacological Properties ofPoria cocos

2011

Poria cocos (Polyporaceae) is a saprophytic fungus that grows in diverse species of Pinus. Its sclerotium, called fu-ling or hoelen, is used in traditional Chinese and Japanese medicine for its diuretic, sedative, and tonic effects. Various studies of this fungus have demonstrated its marked anti-inflammatory activity in different experimental models of acute and chronic inflammation. It is widely used as a constituent of many preparations in Asian medicine, but the number of research papers on its clinical properties is insufficient for establishing its efficacy and safety from a scientific point of view. In this review, we have compiled all the published data concerning the chemistry, pha…

Pharmacological Properties of Shikonin – A Review of Literature since 2002

2013

The naphthoquinone shikonin is the main active principle of Zicao, a traditional Chinese herbal medicine made from the dried root of Lithospermum erythrorhizon. Studies carried out over the past 30 years have provided a scientific basis for the use of Zicao which has been long employed in folk medicine to treat a variety of inflammatory and infectious diseases. In particular, shikonin has been shown to possess many diverse properties, including antioxidant, anti-inflammatory, antithrombotic, antimicrobial, and wound healing effects. The fact that shikonin shows so many beneficial properties has increased the interest in this molecule dramatically, especially in the past few years. The aim o…

Antologia di racconti postmaoisti (1977-1981)

2017

Il volume, corredato da una prefazione del Prof. Paolo Santangelo, comprende una lunga introduzione sullo sviluppo della letteratura cinese contemporanea incentrata sul racconto, e propone, nella traduzione italiana dell'Autrice stessa dall'originale in cinese, dodici racconti scritti fra il 1977 e il 1981. The volume includes a preface written by Prof. Paolo Santangelo, a long introduction to the contemporary Chinese literature based on the short story, and the translations by the Author herself into Italian from the original in Chinese of twelve short stories written between 1977 and 1981.

Vascular Activity of (-)-Anonaine, (-)-Roemerine and (-)-Pukateine, Three Natural 6a(R)-1,2-Methylenedioxyaporphines with Different Affinities for α1…

2004

We have studied the mechanism of action of three 6a( R)-1,2-methylenedioxyaporphines as vasorelaxant compounds. The alkaloids assayed showed different affinities for the three human cloned alpha (1)-adrenoceptor (AR) subtypes stably expressed in rat-1 fibroblasts, showing lower affinity for alpha(1B)-AR with regard to the alpha(1A)- or alpha(1D)-subtypes. These three natural compounds are more potent inhibitors of [ (3)H]-prazosin binding than of [ (3)H]-diltiazem binding to rat cerebral cortical membranes. As all these alkaloids inhibited noradrenaline (NA)-induced [ (3)H]-inositol phosphate formation in cerebral cortex and rat tail artery, they may be safely viewed as alpha (1)-AR antagon…

A comparison of two different formulations for Arc Routing Problems on Mixed graphs

2006

[EN] Arc routing problems on mixed graphs have been modelled in the literature either using just one variable per edge or associating to each edge two variables, each one representing its traversal in the corresponding direction. In this paper, and using the mixed general routing problem as an example, we compare theoretical and computationally both formulations as well as the lower bounds obtained from them using Linear Programming based methods. Extensive computational experiments, including some big and newly generated random instances, are presented.
