Some promising fig cultivars in the Puglia region for breba production
No full textThe fig (Ficus carica L.) is one of the oldest species present in the Mediterranean basin and is currently cultivated in many important countries such as Turkey, Egypt, Morocco, as well as Spain and Italy. In the Puglia region, the presence of several cultivars intended for the production of brebas could complement the already known Petrelli (white-skinned) and Tauro (dark-skinned) cultivars, currently used for both the local and international market. In fact, the Puglia brebas market is characterised by a rather short production calendar based on a very few cultivars and a strong demand from international markets (Germany, UK), which often exceeds product availability. The presence of other cultivars could overcome these difficulties, while providing a product with different organoleptic characteristics. Several surveys to characterise native fig cultivars carried out by the Department of Soil, Plant and Food Science (DiSSPA) – University of Bari have led to the identification and description of some interesting cultivars for breba production. Some of the most promising cultivars are: Fiorone bianco, with light-skinned fruit, high weight (80-90 g) and medium ripeness. Texture is good, and resistance to handling is medium, and the pulp has good acidity and sugars (18.8 °Brix). Among the coloured-skinned accessions, Fiorone della regina has oblong (black-purple) fruit, with high weight (90-100 g), and good sugar content (18.1 °Brix). Because of its low resistance to handling and thin skin with slight cracks, it is recommended for a local market. Troiano Nero produces purple-coloured brebas, high weight (90-110 g), thin pulp and small druplets. Rosso Triggiano has reddish-purple syconia, not very heavy (60-70 g), no cracks, with medium ripening time, light and sweet pulp (18.0 °Brix), and it has good organoleptic and productive characteristics. Rosso comune is an accession that could instead be used for international markets because of its low susceptibility to handling and absence of fruit cracks. Good quality aspects, fine, juicy and sweet pulp (20.0 °Brix) and medium ripening time
Indirect stereoselective determination of enantiomers of furprofen in human plasma by high-performance liquid chromatography
No full textA sensitive and stereoselective liquid chromatographic (HPLC) assay for the S and R enantiomers of furprofen in human plasma has been developed. The assay is based on derivatization with S(−)-1-phenylethylamine with formation of two diastereoisomeric derivatives and on their separation and quantitation using HPLC with uv detection. The method is linear from 25 to 600 ng ml−1 of both enantiomers, with a variation coefficient below 10.8%, and a detection limit of 20 ng ml−1. This procedure is suitable for pharmacokinetic studies
2-aryl-3-phenylamino-4,5-dihydro-2h-benz[g]indazoles with analgesic activity
No full textA series of 2-aryl-3-phenylamino-4,5-dihydro-2H-benz[g]indazoles was synthesized and tested for antiarrhythmic, local
anaesthetic and analgesic activity. The title compounds showed a good antinociceptive activity

Remembering Joseph Anthony Mazzeo
No full textJoseph Anthony Mazzeo, who died on July 6, 1998, is best known to the readers of Dante Studies as the author of two volumes on Dante. Published back to back in 1958 and 1960, these books--Structure and Thought in the 'Paradiso' (Ithaca: Cornell University Press, 1958) and Medieval Cultural Tradition in Dante's 'Comedy' (Ithaca: Cornell University Press, 1960)--bear witness to a white-hot period of meditation on Dante and his cultural matrix that took place in the 1950s, in Mazzeo's scholarly youth
An investigation of drugs abuse in sport performance
No full textDoping in performance sport is a complex and controversial issues. The secrecy that characterizes it hinders the implementation of epidemiological investigations. It involves the entire society. Moreover, the forces that conspire behind doping have always been able not only to identify new substances and new methods but also to steal the new scientific discoveries aimed at the treatment of diseases, for their illegal purposes. The fight against doping has had a strong push, in 2004, with the birth of the first World Anti-doping Code drafted by WADA. The laboratories, the Code, the Biological Passport and the ADAMS are important tools for the fight against doping. The aim study is to show the data relating to the consumption of drugs from 2003 to 2017. A number of the commonly used substances have been discussed and their risks and side effects reviewed
Potential and actual bud fruitfulness: A tool for predicting and managing the yield of table grape varieties
No full textMicroscopic bud dissection can be used to assess grapevine bud fruitfulness prior to winter pruning and long before actual bud fruitfulness can be measured in the vineyard the following spring. Bud dissections should be performed by qualified and trained personnel because inflorescence primordia are difficult to distinguish in some varieties. In the Puglia region, Southeastern Italy, in 2018 and 2019, potential fruitfulness using bud dissection and actual fruitfulness observed in the vineyard were compared for seventeen table grape varieties. The percentage of fertile buds, the number of inflorescence primordia (IP) per node, and the incidence of primary bud necrosis (PBN) were detected with bud dissection to be used either for managing winter pruning or for predicting yield during the successive season. The data were successively compared with fertile buds and actual bud fruitfulness observed in the vineyard during spring. The table grape varieties examined had similar values of fertile buds and fruitfulness both with bud dissection and in the vineyard. The application of longitudinal sections in bud dissections can be an alternative approach (or can be integrated into traditional cross sections) to distinguish IP in some difficult varieties, but the two techniques can be used together for more repeatable results. The bud dissection technique (with both cross and longitudinal sections) can provide useful insights for viticulturist to help guide winter pruning (intensity of pruning and number of canes) and to predict potential yield
Determination of Ofloxacin in Pharmaceutical Forms by High - Performance Liquid Chromatography and Derivative Uvspectrophotometry
No full textA method for the determination of ofloxacin in pharmaceutical forms is described. The procedure is based on the use of the high-performance liquid chromatography, and of the second-derivative ultraviolet spectra, by utilizing the linear relationship between substance concentration and derivative peak amplitude. The minimum concentration detectable by derivative spectrophotometry was 20 ng/ml, and by HPLC 10 ng/ml. The proposed methods, which give thoroughly comparable data, are simple and rapid, and allow precise and accurate results
