CONTROLLING YELLOW-BILLED MAGPIES (Pica nuttalli)

The yellow-billed magpie is a little smaller than the American or black-billed magpie, but the difference in size is very slight. The birds look exactly alike, except one has a black beak and the other has a yellow bill and a bit of yellow skin back of the eye.There are concentrated populations in the Los Banos area, Gustine area, and along the course of the Merced River comprising about 19,100 acres. They are occasionally seen in other areas of the County, but only infrequently observed in the southwestern portion of the County. The heaviest populations are in walnut orchards, dairy farms, almond orchards, turkey ranches and areas adjacent to river bottoms.The yellow-billed magpie may represent a dying ancient race. Since scientific interest has been directed toward its habits and distribution, its range has become more restricted. There are reports that 50 or 60 years ago it was common in many places close to the Coast, where the observer would now look for it in vain. It inhabits only the interior of California west of the Sierra Nevada, chiefly in the Sacramento and San Joaquin Valleys. It haunts stock ranches, because food to its liking is usually plentiful in such places. When cattle and sheep are butchered the refuse attracts magpies. They gather about any dead animal. They feed on grasshoppers, worms and grubs, and of course always look for a reasonable supply of eggs.

'Impulsive compulsivity' in obsessive-compulsive disorder: A phenotypic marker of patients with poor clinical outcome

Although traditionally obsessive-compulsive disorder (OCD) and impulse control disorders (ICD) have represented opposing ends of a continuum, recent research has demonstrated a frequent co-occurrence of impulsive and compulsive behaviours, which may contribute to a worse clinical picture of some psychiatric disorders. We hypothesize that individuals with 'impulsive' OCD as characterized by poor insight, low resistance, and reduced control towards their compulsions will have a deteriorative course, greater severity of hoarding and/or symmetry/ordering symptoms, and comorbid ICD and/or substance use disorders (SUD). The sample consisted of 869 individuals with a minimum score of 16 on the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). Of these, 65 had poor insight, low resistance, and reduced control towards compulsions ('poor IRC') and 444 had preserved insight, greater resistance and better control over compulsions ('good IRC'). These two groups were compared on a number of clinical and demographic variables. Individuals with poor IRC were significantly more likely to have a deteriorative course (p < 0.001), longer duration of obsessions (p = 0.017), greater severity of symmetry/ordering (p < 0.001), contamination/cleaning (p < 0.001) and hoarding (p = 0.002) symptoms, and comorbid intermittent explosive disorder (p = 0.026), trichotillomania (p = 0.014) and compulsive buying (p = 0.040). Regression analysis revealed that duration of obsessions (p = 0.037) and hoarding severity (p = 0.005) were significant predictors of poor IRC. In the absence of specific measures for impulsivity in OCD, the study highlights the utility of simple measures such as insight, resistance and control over compulsions as a phenotypic marker of a subgroup of OCD with impulsive features demonstrating poor clinical outcome.

Participative site-specific agriculture analysis for smallholders

Site-specific agriculture has been adopted in a high-tech context using, for instance, in situ sensors, satellite images for remote sensing analysis, and some other technological devices. However, farmers and smallholders without the economic resources and required knowledge to use and to access the latest technology seem to find an impediment to precision agricultural practices. This article discusses the possibility of adopting precision agriculture (PA) principles for site-specific management but in a low technology context for such farmers. The proposed methodology to support PA combines low technology dependency and a participatory approach by involving smallholders, farmers and experts. The case studies demonstrate how the interplay of low technology and a participative approach may be suitable for smallholders for site-specific agriculture analysis.

Towards a post-traumatic subtype of obsessive-compulsive disorder

We evaluated whether traumatic events are associated with a distinctive pattern of socio-demographic and clinical features of obsessive-compulsive disorder (OCD). We compared socio-demographic and clinical features of 106 patients developing OCD after post-traumatic stress disorder (PTSD; termed post-traumatic OCD), 41 patients developing OCD before PTSD (pre-traumatic OCD), and 810 OCD patients without any history of PTSD (non-traumatic OCD) using multinomial logistic regression analysis. A later age at onset of OCD, self-mutilation disorder, history of suicide plans, panic disorder with agoraphobia, and compulsive buying disorder were independently related to post-traumatic OCD. In contrast, earlier age at OCD onset, alcohol-related disorders, contamination-washing symptoms, and self-mutilation disorder were all independently associated with pre-traumatic OCD. In addition, patients with post-traumatic OCD without a previous history of obsessive-compulsive symptoms (OCS) showed lower educational levels, greater rates of contamination-washing symptoms, and more severe miscellaneous symptoms as compared to post-traumatic OCD patients with a history of OCS.

Mutation and genomic amplification of the PIK3CA proto-oncogene in pituitary adenomas

The tumorigenesis of pituitary adenomas is poorly understood. Mutations of the PIK3CA proto-oncogene, which encodes the p110-α catalytic subunit of PI3K, have been reported in various types of human cancers regarding the role of the gene in cell proliferation and survival through activation of the PI3K/Akt signaling pathway. Only one Chinese study described somatic mutations and amplification of the PIK3CA gene in a large series of pituitary adenomas. The aim of the present study was to determine genetic alterations of PIK3CA in a second series that consisted of 33 pituitary adenomas of different subtypes diagnosed by immunohistochemistry: 6 adrenocorticotropic hormone-secreting microadenomas, 5 growth hormone-secreting macroadenomas, 7 prolactin-secreting macroadenomas, and 15 nonfunctioning macroadenomas. Direct sequencing of exons 9 and 20 assessed by qPCR was employed to investigate the presence of mutations and genomic amplification defined as a copy number ≥4. Previously identified PIK3CA mutations (exon 20) were detected in four cases (12.1%). Interestingly, the Chinese study reported mutations only in invasive tumors, while we found a PIK3CA mutation in one noninvasive corticotroph microadenoma. PIK3CA amplification was observed in 21.2% (7/33) of the cases. This study demonstrates the presence of somatic mutations and amplifications of the PIK3CA gene in a second series of pituitary adenomas, corroborating the previously described involvement of the PI3K/Akt signaling pathway in the tumorigenic process of this gland.

Metachronic malignant transformation of small bowel and rectal endometriosis in the same patient

[ES] Background: Malignant transformation of intestinal endometriosis is a rare event with an unknown rate of incidence. Metachronous progression of endometriosis to adenocarcinoma from two distant intestinal foci happening in the same patient has not been previously reported. Case presentation: We describe a case of metachronic transformation of ileal and rectal endometriosis into an adenocarcinoma occurring in a 45-year-old female without macroscopic pelvic involvement of her endometriosis. First, a right colectomy was performed due to intestinal obstruction by an ileal mass. Pathological examination revealed an ileal endometrioid adenocarcinoma and contiguous microscopic endometriotic foci. Twenty months later, a rectal mass was discovered. An endoscopic biopsy revealed an adenocarcinoma. En bloc anterior rectum resection, hysterectomy and bilateral salpingectomy were performed. A second endometrioid adenocarcinoma arising from a focus of endometriosis within the wall of the rectum was diagnosed. Conclusion: Intestinal endometriosis should be considered a premalignant condition in premenopausal women.

Villa Rasponi a Savignano. Progetto di tutela e valorizzazione di un bene culturale complesso tra architettura storica e paesaggi di Pietro Porcinai.

Oggetto della tesi di laurea è il recupero di Villa Rasponi a Savignano sul Rubicone, un bene storico complesso composto da elementi di varia natura: architettonici e vegetali, di differente pregio, dalla residenza settecentesca agli annessi agricoli di servizio, al parco. Le funzioni d’uso attuali rarefatte e strettamente comuni a quelle originarie, non sono più proponibili per poter garantire la sopravvivenza e la conservazione del complesso. Questo da un punto di vista puramente economico, per l’impegno in termini finanziari che un sito di tali dimensioni richiede, a livello gestionale e circostanziale. Come intervenire su un manufatto di questa natura, tutelandolo, riqualificandolo dal punto di vista architettonico e paesaggistico e, nello stesso tempo, reinserendolo in maniera attiva in un contesto urbano e territoriale dal quale negli anni si è progressivamente distaccato e isolato, chiudendosi nell’accezione di residenza privata? Il progetto, lavorando a vari livelli e confrontandosi con differenti campi disciplinari, dal restauro di un parco storico “firmato” da Pietro Porcinai, all’inserimento di nuovi elementi architettonici, all’analisi di fattibilità finanziaria, si pone principalmente due obiettivi: 1) da un lato intervenire materialmente sul manufatto restaurando gli edifici, anche attraverso la definizione di funzioni che ne permettano la sopravvivenza, e manutenendo il parco storico. In questo senso l’aspetto su cui si insiste maggiormente è il rispetto e la valorizzazione del complesso villa–parco–giardino-annessi come unicum, che assume pregio nella sua totalità e integrità; 2) dall’altro, tenuto conto delle dimensioni, dell’importanza storica, architettonica, culturale e paesaggistica del sito, il progetto intende estendere la sua valenza anche a un intorno in primo luogo locale e poi più ampio, diventando punto di riferimento e polo attrattivo, così come lo era stato nel passato, all’epoca nella quale in esso viveva la principessa Luisa Murat. Non ci si limita dunque a considerare il caso isolato, ma si tiene conto del fatto che la Villa Rasponi sorge all’interno di un contesto, quello della Romagna, di straordinaria ricchezza e molteplicità di espressioni artistiche, architettoniche, naturalistiche che costituiscono un patrimonio di valore, in gran parte scarsamente conosciuto e per nulla. Da qui l’idea di utilizzare una porzione di paesaggio come vetrina e contenitore di informazioni su tutta l’eredità culturale romagnola, legata ad un nuovo modo di intendere il luogo, come contesto che incarna la rete di significati all’interno dei quali le azioni degli uomini diventano fatti culturali. Il complesso della Villa Rasponi, per le sue connotazioni storiche, paesaggistiche, fisiche e posizionali, diventa la concretizzazione di tale idea. Dunque, una porzione di paesaggio che si fa strumento fisico e concettuale, di comunicazione, per trasmettere, valorizzare e promuovere il patrimonio naturale, architettonico e culturale di tutto il territorio in cui è inserito, diventandone icona e sintesi.

Il conflitto tra libertà del mercato interno comunitario e diritti fondamentali nel diritto dell'Unione Europea: la posizione della Corte di Giustizia di Lussemburgo quale garante dei diritti fondamentali

Come indica il titolo, questa ricerca studia il conflitto tra libertà fondamentali del mercato interno dell’Unione europea e dei diritti fondamentali e la posizione della Corte in quanto garante dei diritti nella risoluzione di tali conflitti. La Trattazione considera non solo la Giurisprudenza della Corte di Giustizia, che risolve i conflitti tra libertà del mercato e diritti fondamentali; ma anche l'ordinamento europeo, e il suo rapporto con il diritto nazionale, considerando anche la giurisprudenza delle corti costituzionali e supreme degli Stati membri. L’analisi è svolta in una introduzione; in tre capitoli (Capitolo 1, “Integrazione economica e protezzione dei diritti fondamentali”; Capitlo 2, “Conflitto tra libertà fondamentali di mercato e diritti fondamentali”; Capitolo 3, “La tutela dei diritti fondamentali negli stati membri come limiti all’integrazione europea”) e nelle successive conclusioni.

I Gesuiti americani espulsi in Italia e Joaquín Camaño (1767-1814)

Joaquín Camaño fu un gesuita della Provincia del Paraguay, vissuto nell' esilio italiano la maggior parte della sua vita dal 1767 al 1820. Il suo lavoro e la sua fama possono essere considerati di minore importanza se paragonati a molti altri gesuiti esiliati per ordine di Carlo III alla fine del XVIII secolo in Emilia-Romagna. Attraverso la mia ricerca approfondisco il ruolo di J. Camaño quale personaggio minore che entra nella vita degli altri espulsi tramite un dinamico network relazionale di cui è stato uno dei principali artefici. Il mio obiettivo è stato quello di studiare l'impatto che ebbero gli esuli gesuiti americani, attraverso la vita di Joaquin Camaño, sul mondo intellettuale italiano, europeo ed americano dopo l'espulsione del 1767. Egli, con i suoi studi, si inserisce nella rinnovata e vivace retorica del “Mondo Nuovo” che in quegli anni assume un grande dinamismo. Nato nella modesta città di La Rioja, in Argentina, si erge come un brillante cartografo, etnografo e linguista nel contesto dell'Illustrazione europea grazie alla sua particolare vita da missionario. Dopo l'espulsione, Joaquin Camaño, insieme ad altri numerosi confratelli americani, arriverà a Faenza, nello Stato Pontificio, dedicandosi allo studio della cartografia, dell'etnografia e delle lingue americane. Le sue ricerche si collocano in un momento nevralgico per la storia del pensiero linguistico-antropologico, quando l'osservazione diretta e la riflessione teorica dei fenomeni si misuravano con la grande varietà umana ormai riscontrata nel mondo.

New synthetic strategies towards indolizines and pyrroles

Indolizines and pyrroles are considered as “privileged” structures since their skeletons were found in many biologically active natural products and they possess a wide range of pharmaceutical properties. Syntheses of these small drug-like molecules are very important in medicinal chemistry. However, most existent methodologies are usually limited to specific substitution patterns or require impractical starting materials or expensive catalysts. Therefore, developing new methodologies for the synthesis of indolizines and pyrroles from commercially available or readily accessible sources is highly desirable.rnIn this PhD thesis, several methods has been described for the synthesis of indolizines and pyrroles. In the first part, indolizines carrying substituents in positions 1-3 were synthesized via a formal [3+2]-cycloaddition of pyridinium ylides and nitroalkenes. Pyridinium salts were prepared by N-alkylation of pyridines with cyanohydrin triflates which could be prepared from corresponding aldehydes via a Strecker reaction followed by O-triflylation. Nitroalkenes were simply prepared from the corresponding aldehydes and nitroalkanes in a nitroaldol condensation. Overall, this modular approach allows to construct the indolizine framework with various substitution patterns starting from a pyridine, two different aldehydes and a nitroalkane. In contrast to reported methods, the produced indolizines do not have to contain an electron-withdrawing group.rnIt has also been found that nitrile-stabilized 2-alkylpyridinium ylides cyclize to unstable 2-aminoindolizines via an intramolecular 5-exo-dig cyclization. Using an in situ acetylation of the amino group, N-protected 2-aminoindolizines could be synthesized. As a less common substitution pattern, indolizines carrying substituents in positions 5–8 were synthesized from enones and 2-(1H-pyrrol-1-yl)nitriles obtained from α-aminonitriles using a modified Paal-Knorr pyrrole synthesis. The decoration of the pyridine unit in the indolizine skeleton has been achieved by a one-pot conjugate addition/cycloaromatization sequence.rnIn the second part of the thesis, the diversity-oriented synthesis of pyrroles from 3,5-diaryl substituted 2H-pyrrole-2-carbonitriles (cyanopyrrolines) obtained in a cyclocondensation of enones with aminoacetonitrile hydrochloride is being discussed. 2,4-Di-, 2,3,5-trisubstituted pyrroles, pyrrole-2-carbonitriles and 2,2’-bipyrroles were synthesized in a one- or two-step protocol. While the microwave-assisted thermal elimination of HCN from cyanopyrrolines gave 2,4-disubstituted pyrroles, DDQ-oxidation of the same intermediates furnished pyrrole-2-carbonitriles. Furthermore, 2,3,5-trisubstituted pyrroles were obtained via a C-2-alkylation of the deprotonated cyanopyrrolines followed by the elimination of HCN. Finally, it has also been found that tetraaryl substituted 2,2’-bipyrroles could be synthesized by the oxidative dimerization of cyanopyrrolines using copper (II) acetate at 100 °C.rn

American Society of Clinical Oncology/American Society of Hematology clinical practice guideline update on the use of epoetin and darbepoetin in adult patients with cancer

Purpose To update American Society of Clinical Oncology/American Society of Hematology recommendations for use of erythropoiesis-stimulating agents (ESAs) in patients with cancer. Methods An Update Committee reviewed data published between January 2007 and January 2010. MEDLINE and the Cochrane Library were searched. Results The literature search yielded one new individual patient data analysis and four literature-based meta-analyses, two systematic reviews, and 13 publications reporting new results from randomized controlled trials not included in prior or new reviews. Recommendations For patients undergoing myelosuppressive chemotherapy who have a hemoglobin (Hb) level less than 10 g/dL, the Update Committee recommends that clinicians discuss potential harms (eg, thromboembolism, shorter survival) and benefits (eg, decreased transfusions) of ESAs and compare these with potential harms (eg, serious infections, immune-mediated adverse reactions) and benefits (eg, rapid Hb improvement) of RBC transfusions. Individual preferences for assumed risk should contribute to shared decisions on managing chemotherapy-induced anemia. The Committee cautions against ESA use under other circumstances. If used, ESAs should be administered at the lowest dose possible and should increase Hb to the lowest concentration possible to avoid transfusions. Available evidence does not identify Hb levels � 10 g/dL either as thresholds for initiating treatment or as targets for ESA therapy. Starting doses and dose modifications after response or nonresponse should follow US Food and Drug Administration–approved labeling. ESAs should be discontinued after 6 to 8 weeks in nonresponders. ESAs should be avoided in patients with cancer not receiving concurrent chemotherapy, except for those with lower risk myelodysplastic syndromes. Caution should be exercised when using ESAs with chemotherapeutic agents in diseases associated with increased risk of thromboembolic complications. Table 1 lists detailed recommendations. This guideline was developed through a collaboration between the American Society of Clinical Oncology and the American Society of Hematology and has been published jointly by invitation and consent in both Journal of Clinical Oncology and Blood.
