Gender specific data in patients with acute appendicitis: a single center perspective
BackgroundThe influence of sex, socioeconomic status and other factors on outcomes from acute illness has been found recently with an increasing interest; acute appendicitis is the most frequent urgency in pediatric age. The aim of this study is to show any gender differences. Materials and methodsWe retrospectively analysed the medical records of consecutive patients who underwent surgical exploration for acute appendicitis. Inclusion and exclusion criteria were created. Patient data, demographics, characteristics and outcomes were studied and evaluated on a gender perspective. ResultsAfter reviewing medical charts following the inclusion and exclusion criteria, 364 patients were studied; focusing on final outcomes, it was possible to add news from a gender perspective of appendicitis: gangrenous appendicitis was associated with younger female and older female were more likely to have false positive appendicitis; female had less post-operative pain respect to age-match male for all appendicitis and males had more symptoms respect to females especially for phlegmonous and gangrenous appendicitis. ConclusionsThere is a gender difference in appendicitis; as for adults girls appear to be affected less, have fewer symptoms and have better postoperative result

1H- and 13C-NMR spectra of thiocolchicine and derivatives: A complete analysis
Complete and unambiguous assignments of the 1H- and 13C-nmr spectra of thiocolchicine [1], 3-demethylthiocolchicine [2], and the thiocolchicosides [3] and [4] were made through extensive nmr studies, inclusive of homonuclear COSY and COSYLR, BIRDREV, APT, HETCOR, nOe difference, INEPT, and JMODXH experiments
REDUCTIVE DEHALOGENATION OF ALPHA-HALOKETONES PROMOTED BY HYDROIODIC ACID AND WITHOUT SOLVENT
Several alpha-haloketones have been transformed into the corresponding ketones by reaction with aqueous 57% HI, without solvent. The products are obtained in nearly quantitative yields and with high purity (>99%) even in the case of sterically hindered starting materials
Glycosides. Part 1. New synthesis of 1.2-trans O-aryl glycosides, via tributyltin phenoxides
A new method of glycosidation of phenols has been studied. The reaction of tributyltin phenoxides 2 with 1,2,3,4,6-penta-O-acetyl-D-hexopyranosides 3. 7 and 9, in the presence of tin tetrachloride is described. Glycosides 4, 8 and 10 have been isolated in good yields with high 1,2-trans selectivity. The tributyltin phenoxides 2 have been isolated in quantitative yields, starting from phenols 1 and Bu3SnOMe. This simple method starts from the stable peracetylated sugar, an intermediate of easy access
FINKELSTEIN REACTION WITH AQUEOUS HYDROGEN HALIDES EFFICIENTLY CATALYZED BY LIPOPHILIC QUARTERNARY ONIUM SALTS
The rate of halogen metathesis between halogenoalkanes RX 1-4 (X = F, Cl, Br, I) and aqueous concentrated hydrogen halides HY (Y = Cl, Br, I) is strongly accelerated under phase-transfer catalysis conditions, without solvent. The amount and nature of the nucleophilic species in the organic phase were determined
Isothiazoles. Part IV. Cycloaddition reactions of diaryl-oxazolones and munchnones to 3-diethylamino-4-(4-methoxyphenyl)-isothiazole 1,1-dioxide: A new synthesis of triarylpyrroles
3-Diethylamino-4-(4-methoxyphenyl)-isothiazole 1,1-dioxide (3) readily reacts with oxazolones 2 and munchnones 7 affording with satisfactory yield 3-diethylamino-4,6-diaryl-3a,4-dihydro-3a-(4-methoxyphenyl)-6aH-pyrrol o[3,4-d]isothiazole 1,1-dioxides 4 and 3-diethylamino-4,6-diaryl-5-alkyl-3a-(4-methoxyphenyl)-pyrrolo[3,4-d]i sothiazole 1,1-dioxides 8, respectively. The behaviour of the cycloadducts towards elevated temperatures and/or basic conditions was investigated. Under these conditions the primary products lost SO2 and diethylcyanamide affording 1-alkyl-2,3,5-triarylpyrroles 9 and 1H-2,3,5-triarylpyrroles 10. These latter were found to be better obtained through thermal decompression of N-protected cycloadducts 8 and subsequent deprotecting the final pyrroles
Farmers’ participation in territorial planning: a methodological approach for the case study of Huerta de Valencia
Participation in planning has become progressively important in territory management.
As regards Territorial Planning, farmers are among the main stakeholders. In fact multifunctionality
of agriculture admits a new role to primary sector. In particular the management of open areas is
particularly strategic in peri-urban areas, where competition for resources is highest than in other
areas, especially for the land. In this context, the involvement of farmers as privileged stakeholders
to land management is even more important. This paper proposes a methodological approach for the
evaluation of peri-urban land use plans by farmers, by means of direct surveys on a sample of
Spanish farmers. In particular, it has been considered the "Territorial Action Plan of Valencia’s Huerta” (TAPVH)
Susceptibility to entomopathogens and modulation of basal immunity in two insect models at different temperatures.
Abstract In this work, we analysed the efficacy of different commercial bio-insecticides (Steinernema feltiae, Steinernema carpocapsae, Heterorhabditis bacteriophora and Bacillus thuringiensis) by valuating the mortality induced on two insect models, Galleria mellonella (Lepidoptera) and Sarcophaga africa (Diptera) after exposure to different temperatures (10, 20 and 30 °C). Moreover, we investigated the effects of temperature on the basal humoral immunity of the two target insects; particularly, phenoloxidase (PO) and lysozyme activity. Our results show that G. mellonella is susceptible to all bio-insecticides at all the examined temperatures, except when infected at 10 °C with S. carpocapsae and at 30 °C with S. feltiae and B. thuringiensis. S. africa is more susceptible at 30 °C to all bioinsecticides; whereas, when infected at 10 and 20 °C, H. bacteriophora is the most efficient. Temperature modulates PO activity of both G. mellonella and S. africa, otherwise variations in lysozyme activity is observed only in G. mellonella. Except for a possible correlation between the increased lysozyme activity and the delayed Bt efficacy recorded on G. mellonella at 30 °C, a different resistance to bio-insecticides at different temperatures does not seem to be associated to variations of the host basal immunity, probably due to immunoevasive and immunodepressive strategies of these entomopathogens
α-Pyrones. Part V. Structure effects on the intramolecular cyclization of functionalized 6-pyronylacetamides: synthesis of new 2,5,7-trioxo-pyrano[3,2-c]pyridines
Reaction of arylisocyanates 2 with methyl 2-oxo-2H-pyran-6-acetate 1 and with ylide 4 gave two classes of pyronylacetamides 3 and 5, respectively. Phosphoranes 5 were reduced to the corresponding acetamides 6 with zinc and acetic acid. Compounds 6 were alkylated under solid-liquid PTC conditions using anhydrous potassium carbonate as a base to give the Cα-alkyl derivatives 7 in good yields. Intramolecular cyclization with different bases and solvents of acetamides 3,5-7 to give the new 2,5,7-trioxo-pyrano[3,2-c]pyridines has been studied
