Validation of kinetic modeling of progesterone release from polymeric membranes

Asian Journal of Pharmaceutical Sciences 2018年第1期13卷 54-62页

作者： Analia Irma Romero mercedes Villegas Alicia Graciela Cid Mónica Liliana Parentis Elio Emilio Gonzo José María Bermúdez Instituto de Investigaciones para la Industria Química Universidad Nacional de Salta – Consejo Nacional de Investigaciones Científicas y Técnicas Facultad de Ingeniería Universidad Nacional de Salta

Mathematical modeling in drug release systems is fundamental in development and optimization of these systems, since it allows to predict drug release rates and to elucidate the physical transport mechanisms involved. In this paper we validate a novel mathematical model that describes progesterone(Prg) controlled release from poly-3-hydroxybutyric acid(PHB) membranes. A statistical analysis was conducted to compare the fitting of our model with six different models and the Akaike information criterion(AIC) was used to find the equation with best-fit. A simple relation between mass and drug released rate was found,which allows predicting the effect of Prg loads on the release behavior. Our proposed model was the one with minimum AIC value, and therefore it was the one that statistically fitted better the experimental data obtained for all the Prg loads tested. Furthermore, the initial release rate was calculated and therefore, the interface mass transfer coefficient estimated and the equilibrium distribution constant of Prg between the PHB and the release medium was also determined. The results lead us to conclude that our proposed model is the one which best fits the experimental data and can be successfully used to describe Prg drug release in PHB membranes.

Analogs of Antifungal Indoles Isolated from Aporpium Caryae with Activity Against Sudden-Death Syndrome of Soybean

引用

American Journal of Plant Sciences 2011年第2期2卷 245-254页

作者： Brenda Bertinetti mercedes Scandiani Gabriela Cabrera 不详

Based on the precedent discovery of a weak antifungal indole isolated from Aporpium caryae, which increased its activity when changing the N-alkyl chain, nineteen N-alkyl indoles, with alkyl chains from one to ten carbons and one or two hydroxyls, one amine or bromine functional groups, were prepared and fully characterized by spectroscopic methods. The aim of this study is the search for new synthetic agrochemical leads derived from natural products. The antifungal activity of the synthesized compounds against three fungal strains was measured in vitro. Six compounds presented good activity against Fusarium virguliforme, the causal agent of sudden-death syndrome (SDS) in soybean, in a bioautography assay. Four of them were tested in a germination test and in a greenhouse experiment. All tested compounds, applied as seed treatment, showed antifungal properties being effective to control SDS when there was low level of fungal contamination. Results indicate that some of the tested compounds are acting as growth inhibitors and represent new leads for the treatment of SDS for which no specific treatment has been previously reported.

AIM:To evaluate the predictive value of tissue transglutaminase (tTG) antibodies for villous atrophy in adult and pediatric populations to determine if duodenal biopsy can be ***: A total of 324 patients with celiac disease (CD; 97 children and 227 adults) were recruited prospectively at two tertiary centers. Human IgA class anti-tTG antibody measurement and upper gastrointestinal endoscopy were performed at diagnosis. A second biopsy was performed in 40 asymptomatic adults on a gluten-free diet (GFD) and with normal tTG ***: Adults showed less severe histopathology (26% vs 63%, P<0.0001) and lower tTG antibody titers than children. Levels of tTG antibody correlated with Marsh type in both populations (r=0.661, P<0.0001). Multiple logistic regression revealed that only tTG antibody was an independent predictor for Marsh type 3 lesions, but clinical presentation type and age were not. A cut-off point of 30 U tTG antibody yielded the highest area under the receiver operating characteristic curve (0.854). Based on the predictive value of this cut-off point, up to 95% of children and 53% of adults would be correctly diagnosed without biopsy. Despite GFDs and decreased tTG antibody levels, 25% of the adults did not recover from villous atrophy during the second year after ***: Strongly positive tTG antibody titers might be sufficient for CD diagnosis in children. However, duodenal biopsy cannot be avoided in adults because disease presentation and monitoring are different.

Computer-aided sperm analysis： a useful tool to evaluate patient＇s response to varicocelectomy

引用

Asian Journal of Andrology 2017年第4期19卷 449-452页

作者： Julia I Ariagno Gabriela R Mendeluk Maria J Furlan M Sardi P Chenlo Susana M Curi mercedes N Pugliese Herberto E Repetto Mariano Cohen Clinical Biochemistry Department Male Fertility Laboratory Faculty of Pharmacy and Biochemetry University of Buenos Aires Argentina Urology Department "Jose de San Martin" Clinical Hospital University of Buenos Aires Buenos Aires Argentina (CP1120)

Preoperative and postoperative sperm parameter values from infertile men with varicocele were analyzed by computer-aided sperm analysis （CASA） to assess if sperm characteristics improved after varicocelectomy. Semen samples of men with proven fertility （n = 38） and men with varicocele-related infertility （n = 61） were also analyzed. Conventional semen analysis was performed according to WHO （2010） criteria and a CASA system was employed to assess kinetic parameters and sperm concentration. Seminal parameters values in the fertile group were very far above from those of the patients, either before or after surgery. No significant improvement in the percentage normal sperm morphology （P = 0. 10）, sperm concentration （P = 0.52）, total sperm count （P = 0.76）, subjective motility （%）（P = 0.97） nor kinematics （P = 0.30） was observed after varicocelectomy when all groups were compared. Neither was significant improvement found in percentage normal sperm morphology （P = 0.91）, sperm concentration （P =0. 10）, total sperm count （P = 0.89） or percentage motility （P = 0.77） after varicocelectomy in paired comparisons of preoperative and postoperative data. Analysis of paired samples revealed that the total sperm count （P = 0.01） and most sperm kinetic parameters： curvilinear velocity （P = 0.002）, straight-line velocity （P = 0.0004）, average path velocity （P = 0.0005）, linearity （P = 0.02）, and wobble （P = 0.006） improved after surgery. CASA offers the potential for accurate quantitative assessment of each patient＇s response to varicocelectomy.

Measurement of Transcutaneous Bilirubin with Bilicheck as a Jaundice Screening Method in Neonates in Pediatric Emergency Departments

引用

Open Journal of Pediatrics 2015年第3期5卷 240-247页

作者： Concepcion Miguez mercedes Farinas Salto Rafael Maranon Pediatric Emergency Department Hospital General Universitario Gregorio MaranonMadridSpain

Objectives: To study the reliability of a transcutaneous bilirubinometer (Bilicheck) to determine bilirubin levels in neonates consulting for jaundice in a Paediatric Emergency Department (ED), and to evaluate its usefulness as a screening method. Methods: Prospective observational study realized between June of 2005 and December of2005 inneonates consulting at a paediatric emergency department for jaundice, in whom we realized both transcutaneous and total serum bilirubin measurements (TcB and TSB). We collected demographic variables, analytical variables (serum and transcutaneous bilirubin levels), length of stay in the ED, and need for treatment. Results: 66 children were included aged 2 to 31 days (81% of the sample were 2 to 7 days old). There was a close and statistically significant correlation between TcB and TSB (r = 0.81, p < 0.001). The area under the ROC curve was of 0.90, allowing detecting newborns with jaundice susceptible of treatment with TcB levels ≥ 13 mg/dL (sensitivity 92%, specificity 63, 5%, a positive predictive value 39% and a negative predictive value 97%). The number of venous punctures could be reduced in 50%. The medium stay in the ED was of 2 hours when performing serum measurements. Conclusions: A linear correlation exists between TcB-TSB. TcB measurement cannot replace that of TsB, however it could be used as a screening method in an ED to determine which neonates need confirmation by TsB measurement. The use of transcutaneous bilirubinometer would reduce both the number of painful interventions in neonates and the medium length of stay in ED, consequently reducing iatrogenesis.

Assessment of drug-induced hepatotoxicity in clinical practice: A challenge for gastroenterologists

引用

World Journal of Gastroenterology 2007年第3期13卷 329-340页

作者： Raúl J Andrade mercedes Robles Alejandra Fernández-Castaer Susana López-Ortega M Carmen López-Vega M Isabel Lucena Liver Unit Gastroenterology Service "Virgen de la Victoria" University Hospital and School of Medicine Mlaga Spain Clinical Pharmacology Service "Virgen de la Victoria" University Hospital and School of Medicine Mlaga Spain

Currently, pharmaceutical preparations are serious contributors to liver disease; hepatotoxicity ranking as the most frequent cause for acute liver failure and post-commercialization regulatory decisions. The diagnosis of hepatotoxicity remains a difficult task because of the lack of reliable markers for use in general clinical practice. To incriminate any given drug in an episode of liver dysfunction is a step-by-step process that requires a high degree of suspicion, compatible chronology, awareness of the drug’s hepatotoxic potential, the exclusion of alternative causes of liver damage and the ability to detect the presence of subtle data that favors a toxic etiology. This process is time-consuming and the final result is frequently inaccurate. Diagnostic algorithms may add consistency to the diagnostic process by translating the suspicion into a quantitative score. Such scales are useful since they provide a framework that emphasizes the features that merit attention in cases of suspected hepatic adverse reaction as well. Current efforts in collecting bona fide cases of drug-induced hepatotoxicity will make refinements of existing scales feasible. It is now relatively easy to accommodate relevant data within the scoring system and to delete low-impact items. Efforts should also be directed toward the development of an abridged instrument for use in evaluating suspected drug-induced hepatotoxicity at the very beginning of the diagnosis and treatment process when clinical decisions need to be made. The instrument chosen would enable a confident diagnosis to be made on admission of the patient and treatment to be fine-tuned as further information is collected.
