PORTULACA OLERACEA L. IN THE ERA OF GLOBALISATION: A SPECIES OF GREAT NUTRACEUTICAL VALUE
No full textPortulaca oleracea L. is a common ruderal, synanthropic, cosmopolitan taxon, highly polymorphic, typical of warm sites (Danin and Raus, 2012; Danin et al., 2014; Danin et al., submitted). In Italy its status as a native species is doubtful (Pignatti, 1982). It is well known since the antiquity for its medicinal and nutrient qualities (Bosi et al., 2009): all parts of the plant have therapeutic properties (Gastaldo, 1987). It has been used for a long time as an analgesic, anti-inflammatory, antipyretic, diuretic, emollient, lenitive and anaphrodisiac. Many of such properties have been recently confirmed; furthermore, P. oleracea is very rich in omega-3 polyunsaturated fatty acids (Ezekwe et al., 1999), so that its use is recommended to contrast the excess of fatty acids assumed by fast foods (Picchi and Pieroni, 2005) and its seeds are good to counteract diabetes mellitus (El-Sayed, 2011)
The consequences of social movements: taking stock and looking forward
No full textCitizens of both democratic and authoritarian countries seem to become less supportive of those in power and more willing to use non-conventional forms of collective action for putting pressure on authorities. This was the case, for example, during the past few years, with the major upsurges of protest, in Eastern Europe (Coloured Revolutions), in the Middle East (Arab Spring), in Southern Europe (the Indignados in Spain, the Agonaktismenoi in Greece), in the United States (Occupy Wall Street), in Chile (the Pinquinos), as well as anti-government protests in Hong Kong, Thailand, and South Africa. Such waves of mobilization, comparable in their size to those of the 1960s and 1970s, bring to the fore some important questions for social movement research and call for a deeper understanding of social and political change: When and how does mobilization make a difference? When and how do activists achieve their goals? Is protest a necessary and/or sufficient condition for producing social and political change? Do social movements have any long-term legacies on our societies? Do they change the life choices of those participating in protest activities? How does all this vary both across contexts and across different movements?
These and related questions are not new, but until the 1970s scholars paid little attention to the consequences of social movements as protest was mainly regarded as an irrational action with no instrumental goals (Buechler 2004). Since then, also thanks to some pioneering works (Gamson 1990; Piven and Cloward 1979; Schumaker 1975), a new research field emerged slowly and allowed one of the present authors to note as late as in 1998 that “we still lack systematic empirical analyses that would add to our knowledge of the conditions under which movements produce certain effects” (Giugni 1998: 373). The field was revamped, amongst other things, also thanks to two edited collections entirely devoted to the study of different kinds of the effects of social movements (Giugni et al. 1998, 1999). This sudden focus on social movement outcomes could be related not only to the wave of democratization in the Eastern Europe and Latin America in the 1990s, but also to the fact that sufficient time had passed from the mobilization of the 1968 generation in Western Europe and civil rights mobilization in the United States

Abstract
The authors report their experience using carbon dioxide (CO2) therapy for the treatment of 48 female patients presenting adipose accumulations, located on the thighs, knees, and/or abdomen; a Carbomed Programmable Automatic Carbon Dioxide Therapy apparatus was used. In light of the effects of CO2 on the microcirculation recently described in the literature, we expected this gas, which we administered subcutaneously, to positively affect the physiological oxidative lipolytic process. The aim of our study was to evaluate the effect of this therapy on localized adiposities. As such, we describe the method we used and report the results observed in the areas treated (in terms of reduction in maximum circumference) as well as side effects. Furthermore, we assessed the effect of subcutaneous administration of CO2 on the microcirculation by showing changes in the Laser Doppler signal and in the concentration of transcutaneous oxygen tension (tcPO2). Pre- and posttreatment biopsies of tissues were performed in seven patients in order to study the changes induced by the use of CO2 on both adipose and connective tissues. All data obtained were statistically analyzed; values of P < 0.05 were considered significan
The Consequences of Social Movements
No full textSocial movements have attracted much attention in recent years, both from scholars and among the wider public. This book examines the consequences of social movements, covering such issues as the impact of social movements on the life course of participants and the population in general, on political elites and markets, and on political parties and processes of social movement institutionalization. The volume makes a significant contribution to research on social movement outcomes in three ways: theoretically, by showing the importance of hitherto undervalued topics in the study of social movements outcomes; methodologically, by expanding the scientific boundaries of this research field through an interdisciplinary approach and new methods of analysis; and empirically, by providing new evidence about social movement outcomes from Europe and the United States
Mangani-pargasite, NaCa2(Mg4Mn3+)(Si6Al2)O22(OH)2, a new mineral species of the amphibole supergroup
No full textMangani-pargasite, ideally NaCa2(Mg4Mn3+)(Si6Al2)O22(OH)2, is a new mineral species of the calcium amphibole subgroup of the amphibole supergroup. The type specimen was found on the mine dump of the Långban Fe-Mn-(Ba-As-Pb-Sb) deposit in Värmland, Sweden. Crystal chemical analyses resulted in the empirical chemical formula: A(Na0.90Pb0.07K0.03)Σ1.00B(Ca1.93Mn2+0.07)Σ2.00C(Mg4.25Mn3+0.39Al0.26 Fe3+0.10)Σ5.00T(Si6.35Al1.65)Σ8.00O22W(OH)2. In order to complete the description of this newly approved (IMA 2018-151) mineral we report here additional data to those published in papers by Jonsson and Hålenius (2010) and Hålenius and Bosi (2012). Mangani-pargasite is biaxial positive, with a=1.635(5), b=1.645(5), g=1.660(5) and the measured optic angle 2V is 85(5)°. The dispersion is weak (r>v), and the optic orientation is: Y||b; Z^c=25(3)°. Mangani-pargasite is red to brownish red with weak pleochroism; X=pale reddish brown, Y=pale reddish brown and Z=pale brownish red; X≈Y>Z. The unit-cell parameters are a=9.9448(5), b=18.0171(9), c=5.2829(3) Å, b=105.445(3)°, V=912.39(9) Å3, Z=2, space group C2/m. The ten strongest reflections in the X-ray powder diffraction pattern [d-values in Å, I, (h k l)] are: 8.420, 29, (110); 3.368, 17, (131), 3.279, 49, (240); 3.141, 100, (310); 2.817, 44, (33 0); 2.698, 21, (151); 2.389, 18, (350); 1.904, 29, (510); 1.650, 22, (461) and 1.448, 46, (661)
Impact of bioactive substances on the gastrointestinal tract and performance of weaned piglets: a review
No full textThe EU ban on in-feed antibiotics has stimulated research on weaning diets as a way of reducing post-weaning gut disorders and growth check in pigs. Many bioactive components have been investigated but only few have shown to be effective. Amongst these, organic acids (OA) have been shown to exert a bactericidal action mediated by non-dissociated OA, by lowering gastric pH, increasing gut and pancreas enzyme secretion and improving gut wall morphology. It has been postulated that they may also enhance non-specific immune responses and improve disease resistance. In contrast, relatively little attention has been paid to the impact of OA on the stomach but recent data show they can differently affect gastric histology, acid secretion and gastric emptying. Butyrate and precursors of butyric acid have received special attention and although promising results have been obtained, their effects are dependent upon the dose, treatment duration, initial age of piglets, gastrointestinal site and other factors. The amino acids (AA) like glutamine, tryptophan and arginine are supportive in improving digestion, absorption and retention of nutrients by affecting tissue anabolism, stress and (or) immunity. Glutamine, cysteine and threonine are important for maintaining mucin and permeability of intestinal barrier function. Spray-dried plasma (SDP) positively affects gut morphology, inflammation and reduces acquired specific immune responses via specific and a-specific influences of immunoglobulins and other bioactive components. Effects are more pronounced in early-weaned piglets and under poorer health conditions. Little interaction between plasma protein and antibiotics has been found, suggesting distinct modes of action and additive effects. Bovine colostrum may act more or less similarly to SDP The composition of essential oils is highly variable, depending on environmental and climatic conditions and distillation methods. These oils differ widely in their antimicrobial activity in vitro and some components of weaning diets may decrease their activity Results in young pigs are highly variable depending upon the product and doses used. These studies suggest that relatively high concentrations of essential oils are needed for beneficial effects to be observed and it has been assumed that these plant extracts mimic most of the effects of antibiotics active on gut physiology, microbiology and immunology. Often, bioactive substances protective to the gut also stimulate feed intake and growth performance. New insights on the effects of selected OA and AA, protein sources (especially SDP bovine colostrum) and plant extracts with anti-bacterial activities on the gut are reported in this review
Case report: Successful endoscopic removal of a large rectal foreign body
No full textIncidence of emergency access due to retained large rectal foreign bodies is increased in the last years. Such situations are a challenge because often, due to their size and physical characteristics, the large foreign bodies of the rectum cannot be extracted manually or by endoscopy, thus requiring surgery, as reported in the literature. We report a case of a 59-old male with a retention of a large vegetable rectal foreign body (whole eggplant) successfully subjected to endoscopic removal without the need for surgery
