Contrast sensitivity after implantation of toric iris-claw lenses in phakic eyes.

2004

Abstract Purpose: To evaluate the change in contrast sensitivity after implantation of the Verisyse toric phakic intraocular lens (IOL) (AMO) for the correction of myopia with astigmatism. Setting: Department of Ophthalmology, Johannes Gutenberg-University, Mainz, Germany. Methods: Eighteen eyes had implantation of an iris-supported toric phakic IOL to correct myopia with astigmatism. The mean preoperative spherical equivalent was −12.65 diopters ± 3.6 (SD). The contrast sensitivity with best spectacle correction was determined before surgery and 3 months after surgery using the CSV-1000 HGT instrument (Vector Vision Inc.). Results: Three months after IOL implantation, the mean contrast sen…

Fetal dose measurements and shielding efficiency assessment in a custom setup of (192)Ir brachytherapy for a pregnant woman with breast cancer.

2015

To assess the radiation dose to the fetus of a pregnant patient undergoing high-dose-rate (HDR) (192)Ir interstitial breast brachytherapy, and to design a new patient setup and lead shielding technique that minimizes the fetal dose.Radiochromic films were placed between the slices of an anthropomorphic phantom modeling the patient. The pregnant woman was seated in a chair with the breast over a table and inside a leaded box. Dose variation as a function of distance from the implant volume as well as dose homogeneity within a representative slice of the fetal position was evaluated without and with shielding.With shielding, the peripheral dose after a complete treatment ranged from 50 cGy at…

Self-Reported Restrictive Eating, Eating Disorders, Menstrual Dysfunction, and Injuries in Athletes Competing at Different Levels and Sports

2021

The purpose of this study was to investigate the prevalence of self-reported restrictive eating, current or past eating disorder, and menstrual dysfunction and their relationships with injuries. Furthermore, we aimed to compare these prevalences and associations between younger (aged 15–24) and older (aged 25–45) athletes, between elite and non-elite athletes, and between athletes competing in lean and non-lean sports. Data were collected using a web-based questionnaire. Participants were 846 female athletes representing 67 different sports. Results showed that 25%, 18%, and 32% of the athletes reported restrictive eating, eating disorders, and menstrual dysfunction, respectively. Higher ra…

Screening of pharmacologic adulterant classes in herbal formulations using voltammetry of microparticles.

2013

A solid state electrochemical method for screening different families of adulterant chemicals illegally added to commercial phytotherapuetic formulations is described. The proposed method, based on the voltammetry of microparticles approach, permits a fast and sensitive way to distinguish between anorexics (amfepramone, fenproporex, sibutramine), benzozodiazepinic anxiolytics (clonazepam, flurazepam, alprazolam, midazolam, medazepam, chlordiazepoxide, diazepam), antidepressants (bupropione, fluoxetine, sertraline, paroxetine), diuretics (hydrochlorothiazide, furosemide, chlortalidone, amiloride, spironolactone), and hypoglycemics (glimepiride, chlorpropamide, glibenclamide) based on charact…

L'affitto d'azienda nel fallimento

La proposta esegetica del presente lavoro si articola su due livelli. Sul primo, l'affitto endofallimentare è visto come strumento di riallocazione del rischio di impresa nell'insolvenza, dai creditori al terzo affittuario, e di ripristino del fisiologico rapporto tra potere gestorio e business risk, tipico dell'impresa in bonis. Sul secondo, l'istituto è inquadrato non come anomalia sistematica, ma come coerente momento di valorizzazione della massa attiva da liquidarsi, in una mutata concezione della fase liquidatoria fallimentare, necessariamente integrante un momento gestionale che, per la res azienda, coincide con la continuazione dell'impresa.

Upgrading cytochrome P450 activity in HepG2 cells co-transfected with adenoviral vectors for drug hepatotoxicity assessment

2011

In a number of adverse drug reactions leading to hepatotoxicity, drug metabolism is thought to be involved by the generation of reactive metabolites from non-toxic drugs. The use of hepatoma cell lines, such as HepG2 cell line, for the evaluation of drug-induced hepatotoxicity is hampered by their low cytochrome P450 expression which makes impossible the study of the toxicity produced by bioactivable compounds. Genetically manipulated cells constitute promising tools for hepatotoxicity applications. HepG2 cells were simultaneously transfected with recombinant adenoviruses encoding CYP1A2, CYP2C9 and CYP3A4 to confer them drug-metabolic competence. Upgraded cells (Adv-HepG2) were highly able…

Unione africana e Nazioni Unite: coordinamento o subordinazione nella gestione delle crisi?

2019

The present chapter deals with the relationship between the United Nations and the African Union in the field of international peace and security. The shifting from the Organization for African Unity to the African Union and the establishment of the Peace and Security Council are the answers of African States to the failure of the United Nations to manage the several crisis scenarios in Africa since the early ’90s. If one considers, in fact, the practice of the Union, as regards enforcement actions, the lack of financial resources is the major obstacle to peace and security in Africa. Consequently, the AU Constitutive Act norms which seem to provide for a unilateral right to intervene of th…

The integration of informal business law in the OHADA framework. Methodological reflections

2021

OHADA represents today a successful example of legal integration that offers a modern and reliable legal environment regarding business law in those countries that have joined it. However, such a modern integrated system of business law appears to be unsuited to the informal business sector that still represents a vital segment of the economy in most of the African countries. The paper discusses the attempts that have been made to integrate the informal business sector in the OHADA framework, trying to understand the reasons why they have been substantially unsuccessful and suggests a possible way forward to make such integration possible.

Modelling terror management theory: computer simulations of the impact of mortality salience on religiosity

2017

ABSTRACTThis article outlines the development – and reports on the experimental findings – of two computational models designed to simulate the dynamic systems and behavioural patterns identified and clarified by research on terror management theory. The causal architectures of these models are informed by empirical research on the effects of mortality salience on “religiosity” (and vice versa). They are also informed by research on the way in which perception of personal and environmental hazards activate evolved cognitive and coalitional precautionary systems that can intensify anxiety-alleviating behaviours such as imaginative engagement with supernatural agents postulated within a relig…
