Selective flow-injection biamperometric determination of sulfur-containing amino acids and structurally related compounds
2001
Abstract A simple and selective flow-injection method for the determination of cysteine and methionine is proposed. The method is based on the reaction of the amino acid with chloramine-T and the subsequent reaction of the excess of chloramine-T with an acidic solution of iodide producing a stoichiometric amount of tri-iodide (diminution of the flow-injection analysis (FIA) peak) which is determined biamperometrically using two platinum electrodes polarized at 100 mV. The calibration graph is linear up to 10 μg ml−1 of cysteine and 30 μg ml−1 of methionine; the limit of detection is 0.06 and 0.1 μg ml−1; the repeatability (also as percent of a series of 70 continuous FIA peaks of 5 μg ml−1 …
Mesothelial cyst of the round ligament of the uterus A case report of a rare condition
2021
Le cisti mesoteliali del legamento rotondo sono una rara causa di tumefazione inguinale nelle donne, la loro eziopatogenesi rimare poco chiara e i casi riportati in letteratura sono scarsi. Inoltre, quest’ultime sono raramente prese in considerazione nella diagnosi differenziale delle tumefazioni della regione inguinale nelle pazienti di sesso femminile, ragion per cui sono spesso identificate solo in corso di esplorazione chirurgica e correttamente diagnosticate solo dopo esame istopatologico. Una donna di 57 anni (BMI 37 kg / m2) si è presentato nel nostro dipartimento con una massa inguinale sinistra, con storia di 2 mesi, che causava disagio locale e peggioramento progressivo del dolore…
Diagnosis of polycystic ovary syndrome: from NIH criteria to ESHRE-ASRM guidelines.
2004
In the past, the diagnosis of polycystic ovary syndrome (PCOS) was based on National Institute of Health (NIH) criteria (hyperandrogenism and chronic anovulation) or on sonographic findings of polycystic ovaries. Diffe-rences in diagnosis criteria made it difficult to compare the data of studies coming from different countries. Moreover, there was criticism of both the methods used. In 2003, at a joint meeting of the European Society for Human Reproduction (ESHRE) and the American Society of Reproductive Medicine (ASRM), new guidelines for the diagnosis of PCOS were suggested. According to these guidelines, it is possible to reach a diagnosis of PCOS when at least 2 of these 3 elements are …
Taenia asiatica: the Most Neglected Human Taenia and the Possibility of Cysticercosis
2013
Not only Taenia solium and Taenia saginata, but also Taenia asiatica infects humans. The last species is not included in the evaluation of the specificity of the immunodiagnostic techniques for taeniasis/cysticercosis. There is currently no specific immunodiagnostic method for T. asiatica available. Therefore, due to the fact that molecular techniques (the only tool to distinguish the 3 Taenia species) are normally not employed in routine diagnostic methods, the 2 questions concerning T. asiatica (its definite geographic distribution and its ability to cause human cysticercosis), remain open, turning T. asiatica into the most neglected agent of human taeniasis-cysticercosis.

Tectogonotoechia rivasi n. sp. A new lower Pragian Celtiberian (Spain) Ancystrorhynchoidea rhynchonellid brachiopod
2020
A new lower Pragian Ancystrorhynchoidea rhynchonellid, Tectogonotoechia rivasi n. sp. of the Celtiberian region (Eastern Iberian Chain, EIC, and Eastern Guadarrama, EG) is described and figured. The growth of the new species, from the last neanic stage to the senescent one is specially underlined. T. rivasi n. sp. is characterized as the other species of the genus by the occurrence of a pseudoseptum and a pseudoseptalium in the dorsal interior, with a fine connectivum forming a roofed over structure covering most part of the latter. Exteriorly, the species is an entirely costate, strongly dorsibiconvex, uniplicate form lacking of marginal spines. T. rivasi n. sp. is fairly abundant in the u…
Influence of Perioperative cis-Platinum on Breaking Strength of Bowel Anastomoses in Rats
1985
Adjuvant and perioperative chemotherapy is increasingly being used in the treatment of malignant disease. Therefore, the influence of cytostatic drugs is of interest and is being investigated experimentally. The influence of various drugs is well known and has been described elsewhere (Shamberger et al. 1981). Recently, cis-platinum, an inorganic complex that inhibits DNA synthesis by cross-linking DNA strands, has been introduced. In urology it has shown a surprisingly good effect on testicular tumors and has been used in bladder cancer for palliative treatment, being one of the most potent drugs for this purpose (Yagoda 1979). It is now being combined with cystectomy for curative therapy …
Drug combination studies of curcumin and genistein against rhodesain of Trypanosoma brucei rhodesiense
2018
Curcumin and genistein are two natural products obtained from Curcuma longa L. and soybeans, endowed with many biological properties. Within the last years they were shown to possess also a promising antitrypanosomal activity. In the present paper, we investigated the activity of both curcumin and genistein against rhodesain, the main cysteine protease of Trypanosoma brucei rhodesiense; drug combination studies, according to Chou and Talalay method, allowed us to demonstrate a potent synergistic effect for the combination curcumin-genistein. As a matter of fact, with our experiments we observed that the combination index of curcumin-genistein is < 1 for the reduction from 10 to 90% of rhode…
Adjuncts for ovarian stimulation: when do we adopt “orphan indications” for approved drugs?
2009
Several drugs, shown to be safe for other uses, have proven to be highly effective adjuncts for ovarian stimulation. The authors evaluate these "orphan" indications and make recommendations so that more patients will benefit from their use.
Nanocarriers for respiratory diseases treatment: Recent advances and current challenges
2014
Pulmonary delivery of locally-acting drugs encapsulated in nanocarriers provides several advantages for the treatment of respiratory diseases such as asthma, chronic obstructive pulmonary diseases, cystic fibrosis, tuberculosis and lung cancer. These advantages include, among others, sustained drug delivery to the lungs, reduced therapeutic dose and improved patient compliance. The aim of this review is to give an updated overview on recent advances recorded in the last few years in this field as well as on the major challenges still existing and that remain to be overcome before any clinical application. After an outline on the cellular and extracellular barriers affecting drug delivery to…
