Thorough evaluation of OECD principles in modelling of 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine derivatives using QSARINS.
2020
The human immunodeficiency virus is a lethal pathology considered as a worldwide problem. The search for new strategies for the treatment of this disease continues to be a great challenge in the scientific community. In this study, a series of 107 derivatives of 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine, previously evaluated experimentally against HIV-I reverse transcriptase, was used to model antiretroviral activity. A model of linear regression, implemented in the QSARINS software, was developed with a genetic algorithm for variable selection. The fit of its parameters was good and exhaustive validation, according to the OECD regulatory principles, was performed. Also, the applica…
Fluorine-Containing Drugs Approved by the FDA in 2018
2019
Over the last two decades, fluorine substitution has become one of the essential structural traits in modern pharmaceuticals. Thus, about half of the most successful drugs (blockbuster drugs) contain fluorine atoms. In this review, we profile 17 fluorine-containing drugs approved by the food and drug administration (FDA) in 2018. The newly approved pharmaceuticals feature several types of aromatic F and CF3 , as well as aliphatic (CF2 ) substitution, offering advances in the treatment of various diseases, including cancer, HIV, malarial and smallpox infections.
The Potential Role of Medicinal Mushrooms in the Prevention and Treatment of Gynecological Cancers: A Review
2019
A review of scientific information about the potential role of medicinal mushrooms in the prevention and treatment of gynecological cancers, human immunodeficiency virus, and human papillomavirus infections is reported here. The results of in vivo and in vitro experiments on 16 different species of Basidiomycetes and three Ascomycetes, which possess chemopreventive potential and are effective in clinical application in combination with chemotherapy, are also discussed. Medicinal mushroom extracts confirm an evident efficacy on the reduction of tumor cell proliferation and side effects in patients with gynecological tumors who are undergoing chemotherapy treatments. This review, the first on…
Wissen, Verstehen, Glauben? Eine Fallstudie zur patientenzentrierten Kommunikation und partizipativen Entscheidungsfindung
2019
Zusammenfassung Patientenzentrierte Kommunikation und selbstbestimmte Entscheidungen gelten heutzutage als wichtige Aspekte der Arzt-Patienten-Beziehung. Im klinischen Alltag ist die Umsetzung dieser Konzepte jedoch immer wieder erschwert. In diesem Beitrag wird anhand eines Fallbeispiels diskutiert, worin die Grenzen der partizipativen Entscheidungsfindung bestehen und wieso das Vertrauen in die Handlungslogik der Institution insbesondere dann relevant wird, wenn es nur geringe Spielräume für eigene Entscheidungen gibt.
The molecular epidemiology of HIV-1 in the Comunidad Valenciana (Spain): analysis of transmission clusters
2017
AbstractHIV infections are still a very serious concern for public heath worldwide. We have applied molecular evolution methods to study the HIV-1 epidemics in the Comunidad Valenciana (CV, Spain) from a public health surveillance perspective. For this, we analysed 1804 HIV-1 sequences comprising protease and reverse transcriptase (PR/RT) coding regions, sampled between 2004 and 2014. These sequences were subtyped and subjected to phylogenetic analyses in order to detect transmission clusters. In addition, univariate and multinomial comparisons were performed to detect epidemiological differences between HIV-1 subtypes, and risk groups. The HIV epidemic in the CV is dominated by subtype B i…

However, data are lacking on the epidemiology globally. We perfor…
CD3ε Expression Defines Functionally Distinct Subsets of Vδ1 T Cells in Patients With Human Immunodeficiency Virus Infection
2018
Human γδ T cells expressing the Vδ1 T cell receptor (TCR) recognize self and microbial antigens and stress-inducible molecules in a major histocompatibility complex -unrestricted manner and are an important source of innate interleukin-17. Vδ1 T cells are expanded in the circulation and intestines of patients with human immunodeficiency virus (HIV) infection. In the present study, we show that patients with HIV have elevated frequencies, but not absolute numbers, of circulating Vδ1 T cells compared to control subjects. This increase was most striking in the patients with Candida albicans co-infection. Using flow cytometry and confocal microscopy, we identify two populations of Vδ1 T cells, …
Evaluation of HIV transmission clusters among natives and foreigners living in Italy
2020
We aimed at evaluating the characteristics of HIV-1 molecular transmission clusters (MTCs) among natives and migrants living in Italy, diagnosed between 1998 and 2018. Phylogenetic analyses were performed on HIV-1 polymerase (pol) sequences to characterise subtypes and identify MTCs, divided into small (SMTCs, 2&ndash
