Silvia Minoia, Angelo Petrozza, Olimpia D'Onofrio, Florence Piron, Giuseppina Mosca, Giovanni Sozio, Francesco Cellini, Abdelhafid Bendahmane, Filomena Carriero
BMC Research Notes , 2010, DOI: 10.1186/1756-0500-3-69
Abstract: To apply TILLING to tomato, a new mutant collection was generated in the genetic background of the processing tomato cultivar Red Setter by treating seeds with two different ethylemethane sulfonate doses (0.7% and 1%). An associated phenotype database, LycoTILL, was developed and a TILLING platform was also established. The interactive and evolving database is available online to the community for phenotypic alteration inquiries. To validate the Red Setter TILLING platform, induced point mutations were searched in 7 tomato genes with the mismatch-specific ENDO1 nuclease. In total 9.5 kb of tomato genome were screened and 66 nucleotide substitutions were identified. The overall mutation density was estimated and it resulted to be 1/322 kb and 1/574 kb for the 1% EMS and 0.7% EMS treatment respectively.The mutation density estimated in our collection and its comparison with other TILLING populations demonstrate that the Red Setter genetic resource is suitable for use in high-throughput mutation discovery. The Red Setter TILLING platform is open to the research community and is publicly available via web for requesting mutation screening services.Tomato (Solanum lycopersicum) is one of the most important vegetable plants in the world. Its fruits are end products both for the fresh market and food processing industry. Tomato presents a relatively small genome highly syntenic to others economically important Solanaceae species and was selected as a reference species for sequencing a Solanaceae genome. In addition to the availability of a number of genomic resources, including transcriptome [1-3] and metabolome [4], large collections of genetic resources are available to dissect the biochemical and the metabolic pathways in tomato [5]. Large EMS and fast neutron mutant collections, in the background of M82 tomato cultivar, have been generated and more then 3,000 phenotype alterations catalogued [6].

Evaluating National Socialism as a “True” Fascist Movement  [PDF]
Angelo Nicolaides
Advances in Historical Studies (AHS) , 2013, DOI: 10.4236/ahs.2013.21004
Abstract: The terms “Fascism” and “Nazism” are often linked, and at times they are regarded as one and the same ideology. The question raised is what is the distinction between Fascism and National Socialism or Nazism? A closer look at the ideas of fascism and National Socialism reveals certain affinities and overlaps with other ideologies, like Socialism, Liberalism and Conservatism. Fascism had many contradictory strands and despite deep unresolved tensions between ideas of race, nation and state in both National Socialism and fascism, the former is regarded as a “true” fascist movement. This article strives to ascertain the main differences and similarities between National Socialism and fascism and to ascertain if National Socialism could be considered to be a “true” fascist movement.
A Review of Carbonatite Occurrences in Italy and Evaluation of Origins  [PDF]
Angelo Paone
Open Journal of Geology (OJG) , 2013, DOI: 10.4236/ojg.2013.32011
Abstract:

This review and evaluation seeks to clarify the controversial origins of the Umbria-Latium Ultra-alkaline District (ULUD) and the Vulture carbonatitic occurrence (Intramontane Ultra-alkaline Province, IUP) and their relation to the Roman Comagmatic Province (RCP). Generally, the geochemical and isotopic features of the IUP can be linked to those of the RCP. Hence, the rocks of the ULUD district, together with part of the Tuscan and Roman Province generated in the last 2 Ma can be ascribed to a complex interplay of two subduction events related to magmatism associated with the European and Adria slabs associated with the effect of a slab window below the Italian Peninsular. Carbonate sediments together with pelagic-terrigenous sediment played a major role in the metasomatism of the mantle wedge beneath the IUP, and perhaps all along the transect from southern Italy (Eolian Islands magmatism) to north-central Italy (Tuscan and Umbria magmatism). A diffuse CO2 + H2O metasomatic front produced the condition necessary for the formation of carbonatitic magmatism. However, even where carbonatites are related to continental rift system (i.e., OIB), an origin for MORB-sediment convective recycling melting in the mantle has been hypothesized [i.e., 1].

The Use of Plants and Wildflowers as Bioremediation for Contaminated Soils in the Hong Kong S.A.R.  [PDF]
Angelo Indelicato
Open Journal of Soil Science (OJSS) , 2014, DOI: 10.4236/ojss.2014.49032
Abstract: Heavy metal contamination of the biosphere has increased sharply over the last century. Anthropogenic activities such as industrialisation and demographic growth can be considered as the main causes of it. Soil contamination affects every organism and poses major environmental and human health problems worldwide. The issue has been addressed in the past and a few methodologies have been developed in order to effectively clean up the contaminated areas. However, many of these remedies are very aggressive and can damage the soil. This paper focuses on the use of gentler techniques, which take advantage of the properties of several plants and wildflowers that absorb heavy metals and polycyclic aromatic hydrocarbons, and their potential application in megacities such as Hong Kong.
Pb Isotopes Data from the Campanian Volcanic Province: A Model to Generate These Distinctive Pb Isotopic Variations  [PDF]
Angelo Paone
Open Journal of Geology (OJG) , 2015, DOI: 10.4236/ojg.2015.51001
Abstract: A broad set of samples from the CVP has been analyzing Pb isotopes. Campanian Volcanic Province (CVP) has been produced by various ranges of mixing between three components: 1) MORB, 2) Hercynian basement and 3) upper crust. Anyhow, the upper crust that has modified the Pb isotopic composition also shows trends towards an Achaean upper crust. This is consistent for all Mediterranean area. This is not in contrast with the past plate tectonic reconstruction. Also the surface sediments (GLOSS) may have been a mixing between the Achaean upper crust and a Hercynian component with an implication worldwide due to the rock cycle processes.
Volatiles (S-CO2-H2O-Cl-F) Behavior during the AD 1944 Eruption  [PDF]
Angelo Paone
International Journal of Geosciences (IJG) , 2015, DOI: 10.4236/ijg.2015.63017
Abstract: The AD 1944 is the last vulcanian-effusive eruption of Vesuvius volcano. I have reviewed most of the major and volatile elements in order to better understand the eruptive dynamic of this hazardous volcano. These volcanic products were basically formed by at least two main petrogenetic mechanisms: 1) mixing, 2) crystal fractionation. Crystal fractionation plays a major role in the evolution of the volcanic products of the AD 1944 eruption. According to the major elements data, several fractionation lines can be employed. Volatile data are analyzed in sequence. Indeed, the volatile data allow an insight into the exsolution and degassing processes occur during the growth and eruption of the AD 1944 eruption. Some inferences are also made on the exsolution and degassing depth. The volatile data illustrate a sequential order of exsolution for the AD 1944 eruption: Cl-H2O-CO2-S and finally as volatile phase degassed fluorine. The eruption has not interacted with external water. An early exsolution of Cl in Cl-rich magmas is also confirmed by experimental and geological studies (3 - 4 Kbars) coinciding with the deep magma reservoir.

Abstract: 0.4%–5% of patients with acute myocardial infarction die from sudden and severe mitral regurgitation due to a complete rupture of a papillary muscle [1]. Most commonly, the posteromedial papillary muscle is involved, but in 20% of cases, the anterolateral papillary muscle is involved. The muscle rupture may represent a rare mechanical complication of a blunt chest trauma, or may be due to sepsis [2].Spontaneous rupture of the papillary muscle, secondary to isolated papillary muscle infarction, in the absence of coronary artery disease, is incommon or rare.We describe a case of a spontaneous acute papillary muscle rupture in the absence of a history of ischemic cardiopathy or blunt chest trauma or sepsis.A 48 year old man was transferred to the intensive care unit in June 2008 with signs and symptoms of cardiogenic shock after extreme exercise. He was a farmer and had been lifting a bale of corn. He collapsed immediately after exercise. Past medical history was positive for heavy smoking, severe arterial hypertension and hypercholesterolemia. There was no previous history of chest pain, heart murmurs or drug abuses. Up until the even the patient had appeared to be in good health and had not been on medication. There was no history of trauma to the chest.Physical examination revealed congestive heart failure and a loud pan-systolic apical murmur, radiating posteriorly. The ECG showed sinus tachycardia. Chest X-ray showed pulmonary venous congestion and was suspicion of an infiltrate in the right lower lobe which could be consistent with the patient's pyrexia. An urgent echocardiogram showed normal systolic function, severe left ventricular hypertrophy (14 mm septum wall), an increased end-diastolic diameter of the left ventricle (58 mm) and posterior and anterior mitral valve prolapse with severe mitral valve regurgitation. Coronary angiography and a left ventricular angiogram showed normal coronary arteries and a good left ventricular function with massive mitral reg

Abstract: We describe the case of a 57-year-old Caucasian man who underwent laparoscopic cholecystectomy for the evaluation of a gallbladder polyp that had been incidentally detected by ultasonography. Histologically, his lesion was composed of monomorphic cells that contained small round nuclei and that were organized in small nodular, trabecular, and acinar structures. His cells were positive for chromogranin A and synaptophysin, and a diagnosis of "typical" carcinoid of the gallbladder was made. His post-operative computerized axial tomography, 111In-pentetreotide scintigraphy, and hormone-specific marker results were negative. He is disease-free 45 months after surgical treatment.Characteristic pathological findings of the gallbladder neuroendocrine tumors predict the prognosis. Whereas classical carcinoids of the gallbladder only rarely have a metastatic or invasive phenotype, the "atypical" variants are more aggressive and are associated with a poorer prognosis. Given the difficulty in distinguishing between benign and malignant lesions in the pre-surgical setting, we tend to consider each polypoid-like lesion of the gallbladder to be a high-risk lesion if it is larger than 1 cm and, as a result, to emphasize the need for cholecystectomy in all cases, relying on the pathological and immunohistochemistry analyses for the final diagnosis.Carcinoids are rare neuroendocrine tumors (NETs) derived from enterochromaffin or Kulchitsky cells, which are widely distributed in the body [1,2]. Consequently, NETs can be found in any location of the body, although the sites most commonly affected are the gastrointestinal and bronchopulmonary tracts, representing approximately 67% and 25% of cases, respectively [3]. NETs are histologically varied entities and can range from indolent, unrecognized neoplasms to highly active, metastatic secretory tumors [4]. Prognostic factors include primary tumor site, histological differentiation, tumor size, angioinvasion, infiltrative growth, and pr

Physics , 2013,
Abstract: A functionally graded Al-doped ZnO structure is presented which combines conductivity, visible transparency and light scattering with mechanical flexibility. The nano and meso-architecture, constituted by a hierarchical, large surface area, mesoporous tree-like structure evolving in a compact layer, is synthesized at room temperature and is fully compatible with plastic substrates. Light trapping capability is demonstrated by showing up to 100% improvement of light absorption of a low bandgap polymer employed as the active layer.
MADS Box Transcript Amount is Affected by Ethylene during Abscission  [PDF]

American Journal of Plant Sciences (AJPS) , 2011, DOI: 10.4236/ajps.2011.23035
Abstract: Thinning of young fruit is an important agronomical practice to ensure the maximum economic production. This practice is based on the control of the natural self thinning process occurring during fruit development. At the early stages of fruit development (fruitlet), the vegetative part of the tree is competing with the reproductive part of the tree and within the fruit clusters the different fruitlets are competing with each other. As a result the least fit organ abscises, Ethylene and auxin play a central role in this event but the role of ethylene is not thoroughly understood because in other systems abscission occurs partly with ethylene independent processes. We have followed the early development of fruitlets and studied the transcription patterns of MADS-box and ethylene related transcripts. Furthermore, we verified that ethylene has an effect on the expression of some ethylene related and MADS BOX genes. We propose that the ethylene burst during abscission induction is similar to a stage 2 ethylene system and it is related to fruitlet growth by affecting transcript amount of MADS-BOXes which modulate seed development and cortex growth.
