Applications and Limitations of Dendrimers in Biomedicine
Biomedicine represents one of the main study areas for dendrimers, which have proven to be valuable both in diagnostics and therapy, due to their capacity for improving solubility, absorption, bioavailability and targeted distribution. Molecular cytotoxicity constitutes a limiting characteristic, especially for cationic and higher-generation dendrimers. Antineoplastic research of dendrimers has been widely developed, and several types of poly(amidoamine) and poly(propylene imine) dendrimer complexes with doxorubicin, paclitaxel, imatinib, sunitinib, cisplatin, melphalan and methotrexate have shown an improvement in comparison with the drug molecule alone. The anti-inflammatory therapy focus…
ADVERSE EFFECTS OF GONADOTROPINS USED IN INFERTILITY TREATMENT
Introduction: Infertility represents a problem for more and more couples all over the world, including in Romania. Thus, more and more women need to resort to drugs to treat infertility, treatments which are not without adverse reactions (Boivin et al., 2007). Modern therapy brings significant benefits in the treatment of infertility. Despite all the benefits, the controlled ovarian stimulation treatment does not lack the possibility of adverse reactions to the administered drugs.
 Objectives: The aim of this study was to determine the potential adverse reactions experienced by patients during the treatment with gonadotropins followed by assisted conception
 Methods: A study was d…
An Exploratory Research of 18 Years on the Economic Burden of Diabetes for the Romanian National Health Insurance System
The prevalence of diabetes mellitus (DM) rises constantly each year worldwide. Because of that, the funds allocated for the DM treatment have increased over time. Regarding the number of DM cases, Romania is among the top ten countries in Europe. Based on the National Diabetes Programme (NDP), antidiabetic drugs and other expenditures (Self-monitoring blood glucose (SMBG) test, HbA1c, insulin pumps/insulin pumps supplies) are free of charge. This programme has undergone many changes in drugs supply, in the last two decades: re-organizing the NDP, authorization of new molecules with high prices (e.g., SGLT-2 inhibitors, etc.) or new devices (e.g., insulin pumps, etc.) The main purpose of thi…
Dendrimers as Non-Viral Vectors in Gene-Directed Enzyme Prodrug Therapy.
Gene-directed enzyme prodrug therapy (GDEPT) has been intensively studied as a promising new strategy of prodrug delivery, with its main advantages being represented by an enhanced efficacy and a reduced off-target toxicity of the active drug. In recent years, numerous therapeutic systems based on GDEPT strategy have entered clinical trials. In order to deliver the desired gene at a specific site of action, this therapeutic approach uses vectors divided in two major categories, viral vectors and non-viral vectors, with the latter being represented by chemical delivery agents. There is considerable interest in the development of non-viral vectors due to their decreased immunogenicity, higher…
