Stabilization of unilamellar catanionic vesicles induced by β-cyclodextrins: A strategy for a tunable drug delivery depot.

2018

The limited stability of catanionic vesicles has discouraged their wide use for encapsulation and controlled release of active substances. Their structure can easily break down to form lamellar phases, micelles or rearrange into multilamellar vesicles, as a consequence of small changes in their composition. However, despite the limited stability, catanionic vesicles possess an attractive architecture, which is able to efficiently encapsulate both hydrophobic and hydrophilic molecules. Therefore, improving the stability of the vesicles, as well as the control on unilamellar structures, are prerequisites for their wider application range. This study focuses on the impact of β-cyclodextrins fo…

Role of leuprolide acetate depot in hysteroscopic surgery: a controlled study.

1993

Objective To evaluate leuprolide acetate (LA) depot (Enantone Depot, Takeda, Italy) when administered preoperatively in hysteroscopic surgery. Design Prospective, comparative study. Setting University Clinic of Obstetrics and Gynecology. Patients One hundred ninety-three patients (114 pretreated with LA depot and 79 controls) who underwent hysteroscopic surgery for uterine septa (group A), submucous fibroids (group B), and abnormal uterine bleeding (group C). Results In groups B and C there was a significant reduction in the operating time, bleeding during the operation, and the amount of distention medium required after LA depot administration, but no significant differences in surgical fe…

In-situ forming gel-like depot of a polyaspartamide-polylactide copolymer for once a week administration of Sulpiride

2015

Abstract Objectives An in-situ forming gel-like depot, prepared by using an appropriate polyaspartamide-polylactide graft copolymer, has been employed to release in a sustained way sulpiride. Methods α,β-poly(N-2-hydroxyethyl)-D,L-aspartamide-g-polylactic acid (PHEA-g-PLA) has been used as a polymer component. Its physicochemical properties make possible to dissolve it in N-methyl-2-pyrrolidone, with the obtainment of a solution able to form a gel-like depot once injected into a physiological medium. Cell compatibility of PHEA-g-PLA depot has been investigated, using murine dermal fibroblasts as cell model. 3-(4,5-Dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazo…

Comparing Long-Acting Antipsychotic Discontinuation Rates Under Ordinary Clinical Circumstances: A Survival Analysis from an Observational, Pragmatic…

2021

Background Recent guidelines suggested a wider use of long-acting injectable antipsychotics (LAI) than previously, but naturalistic data on the consequences of LAI use in terms of discontinuation rates and associated factors are still sparse, making it hard for clinicians to be informed on plausible treatment courses. Objective Our objective was to assess, under real-world clinical circumstances, LAI discontinuation rates over a period of 12 months after a first prescription, reasons for discontinuation, and associated factors. Methods The STAR Network ‘Depot Study’ was a naturalistic, multicentre, observational prospective study that enrolled subjects initiating a LAI without restrictions …

Time-Dependent Multiple Depot Vehicle Routing Problem on Megapolis Network under Wardrop's Traffic Flow Assignment

2018

In this work multiple depot vehicle routing problem is considered in case of variable travel times between nodes on a metropolis network. This variant of the classic multiple depot vehicle routing problem is motivated by the fact that in urban contexts variable traffic conditions play an essential role and can not be ignored in order to perform a realistic optimization. Time-travel matrices corresponding to each period of planning horizon were formed by solving the traffic assignment problem in conjunction with shortest path problem. Routing problem instances include from 20 to 100 customers randomly chosen from a road network of Saint-Petersburg. The results demonstrate that taking into ac…

Endocrine and Clinical Evaluation of 107 Patients With Advanced Prostatic Carcinoma Under Long-Term Pernasal Buserelin or Intramuscular Decapeptyl De…

1988

Three major assumptions emerged from these clinical and endocrine long-term studies. First, buserelin, given pernasally in the conventional doses, and Decapeptyl microcapsules administered intramuscularly in 5-week intervals are equally effective in terms of their long-term castration effect in previously untreated patients with prostatic carcinoma. However, Decapeptyl causes complete LH and subsequent testosterone down-regulation 1 week earlier than buserelin. Furthermore, this treatment is more convenient, and the compliance is better. Both LHRH analogues are equally well tolerated. Second, in groups of prostate cancer patients with far advanced disease treated with palliative intention, …

Data from: Factors associated with first- versus second-generation long-acting antipsychotics prescribed under ordinary clinical practice in Italy

2019

Background. For many years, long-acting intramuscular (LAI) antipsychotics have been prescribed predominantly to chronic and severe patients, as a last resort when other treatments failed. Recently, a broader and earlier use of LAIs, particularly second-generation LAIs, has been emphasized. To date, few studies attempted to frame how this change in prescribing took place in real-world practice. Therefore, this study aimed to describe the clinical features of patients prescribed with LAIs, and to explore possible prescribing differences between first- and second-generations LAIs under ordinary clinical practice in Italy. Methods. The STAR Network "Depot" Study is an observational, longitudin…

Le dépôt de Quitteur (Haute-Saône) et les dépôts de bronzes en contexte d’habitat au Bronze final

2020

Le petit dépôt de bronzes découvert à Quitteur (commune de Beaujeu-Saint-Vallier-Pierrejux et Quitteur ; Haute-Saône - France), sur une moyenne terrasse de la Saône, est composé de trente-deux objets comprenant un assortiment d’éléments de parures (boutons à bélière, pendeloque, anneaux) associés à un couteau à manche massif et une armature de flèche. Le lieu de découverte du dépôt, dans l’espace occupé par les vestiges d’un habitat contemporain du RSFO, s’écarte de la majorité des dépôts de bronzes isolés comme l’archéologie les perçoit habituellement. À l’aide de quelques comparaisons géographiquement proches, il est alors permis de nous interroger sur le caractère apparemment inhabituel …
