ECONOMETRIC MODELLING FOR SIMULATING THE ECONOMIC IMPACT OF STRUCTURAL REFORMS IN ROMANIA: A PILOT PROJECT

The aim of this research to set up a system which helps to estimate the impact of public funding from projects. The impact depends on all factors affecting demand for the good or service provided under the structural intervention at stake. Thus, the present research provides a pilot econometric model for simulating the main mechanisms that lead to public investment impact from the perspective of 42 counties for the year 2006. The importance of this time span is due to the fact that it represents the end of the second programming period for European Union funds and it reveals the impact of economic structural measures at microeconomic level. Data observed to estimate the linear regression model contain at least 50 observations and the t test, the F test and the coefficients of determination are used to analyse the worthiness of the model after prior estimation of the parameters. Findings showed that the independent element of the model is unbiased, whilst the regression coefficient is biased.econometric modeling, public spending, evaluation, monitoring, pilot project, micoreconomics

Development and validation of Triticum phytobiological method as an alternative procedure for investigating in vivo acute toxicity on mice

The goal of this study was to validate an alternative method for determining in vivo acute toxicity using vegetal material instead of laboratory animals, starting from the phytobiological method known also as the Triticum technique. We set out to demonstrate that vegetal cells have similar sensitivity to some toxic agents as animal cells, in which case a statistical correlation could be established. A series of new compounds synthesized by the Romanian National Institute for Chemical Pharmaceutical Research and Development as potential β3 adrenergic receptors agonists were tested for their acute toxicity using classic animal exposure models, before investigating possible anti-diabetic and anti-obesity effects. We then determined whether similar conclusions might be reached exposing vegetal material to the same agents. We successfully demonstrated that plants are affected in a very similar way as animals when exposed to some potentially toxic agents, providing new possibilities for ending unethical animal experiments

Synthesis and Pharmacological Research Regarding New Compounds with Quinazolin-4-One Structure

The quinazoline scaffold is found in the chemical structure of many marketed drugs used in CNS disorders as antidepressants, anxiolytics, or hypnotics. Also, the carbamate ester derivatives have different certain therapeutic actions, such as hypnotic or parasympathomimetic ones. We have obtained new 4(3H)-quinazolinones by bringing together in the same structure the quinazoline nucleus and carbamate ester group. The compounds named Q1–Q5 were characterized by measuring the melting points, by determining the infrared and NMR spectra, and by elemental analysis. The pharmacological tests evidenced that the compounds have a very low acute toxicity, lethal doses being >2000 mg/kg bw. The compounds had different actions observed in forced swimming test (FST), tail suspension test (TST), or elevated plus maze (EPM), probably influenced by the presence of different radicals on the nucleus. Thus, Q1 with a nitro group in structure manifested the highest antidepressant effect, showing a reduction of immobilization time in FST and TST. On the other hand, Q3 and Q5, with two groups methoxy, respective ethoxy, had a slight anxiolytic effect, highlighted by an increase of the time spent in open arms and a decrease of the time spent in closed arms of EPM

Specific features of clostridium difficile colitis in patients with inflammatory bowel disease

Through its specific biological, epidemiological, diagnostic and infection management features, Clostridium difficile infection (CDI) can be considered a major health concern, especially in inflammatory bowel disease (IBD) patients. In this particular infection, many IBD risk factors are triggered due to bowel inflammation, antibiotics use, microbiota changes, immunosuppressive therapy use and surgical intervention. Thus, each IBD and diarrhea patient must be tested for CDI. Clinical features show different initial infectious stages such as mild, fulminate and refractory. It has been shown that CDI presents recurrent episodes. CDI treatment consists of metronidazole, vancomycin or fidaxomicin, as well as prophylactic measures. It was recently shown that antibiotic doses must be gradually reduced in order to avoid CDI relapses. Fecal transplantation, effective in CDI management, remains controversial in CDI patients with concurrent IBD
