PMT: New analytical framework for automated evaluation of geo-environmental modelling approaches

2019

Geospatial computation, data transformation to a relevant statistical software, and step-wise quantitative performance assessment can be cumbersome, especially when considering that the entire modelling procedure is repeatedly interrupted by several input/output steps, and the self-consistency and self-adaptive response to the modelled data and the features therein are lost while handling the data from different kinds of working environments. To date, an automated and a comprehensive validation system, which includes both the cutoff-dependent and –independent evaluation criteria for spatial modelling approaches, has not yet been developed for GIS based methodologies. This study, for the fir…

Persistence of symptoms in primary somatoform vertigo and dizziness: a disorder "lost" in health care?

2013

The aim of this study was to perform a 3-year follow-up of primary somatoform vertigo and dizziness (SVD) regarding health care use and treatment. Ninety-two patients with dizziness underwent detailed vestibular neurophysiological testing and a Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Psychometric assessments comprised the Vertigo Symptom Scale, the Vertigo Handicap Questionnaire, the SCL-90-R, and the Short-Form-36 Health Survey. At the 3-year follow-up, 65 patients with primary SVD (anxiety, n = 29; depression, n = 14; somatoform disorders, n = 22) were reassessed (70.7% response). The patients improved in symptom severity (p…

Extemporaneous formulations in Germany – relevance for everyday clinical practice

2017

Background Extemporaneous formulations broaden the spectrum of therapeutic options for topical treatment in particular and thus improve patient care. The latest amendment to the Regulation on the Operation of Pharmacies issued in 2012 brought about changes in prescribing and manufacturing practices. The aim of the present study was to assess the relevance of extemporaneous formulations in everyday clinical practice. Methods We used data from the German Institute for Drug Use Evaluation (DAPI) to analyze the prescribing practice for compounded preparations in Germany between the fourth quarter of 2011 and the third quarter of 2014. In doing so, we determined the total cost associated with ex…

Hepatocyte cell lines: their use, scope and limitations in drug metabolism studies.

2006

Gaining knowledge on the metabolism of a drug, the enzymes involved and its inhibition or induction potential is a necessary step in pharmaceutical development of new compounds. Primary human hepatocytes are considered a cellular model of reference, as they express the majority of drug-metabolising enzymes, respond to enzyme inducers and are capable of generating in vitro a metabolic profile similar to what is found in vivo. However, hepatocytes show phenotypic instability and have a restricted accessibility. Different alternatives have been explored in the past recent years to overcome the limitations of primary hepatocytes. These include immortalisation of adult or fetal human hepatic cel…

Chemistry and biology of new marine alkaloids from the indole and annelated indole series.

2003

Chemistry and biology of marine natural products from the indole and annelated indole series have become an attractive research field for development of new pharmacological lead substances. In the past years some of the isolated natural organic compounds were synthesized by chemists and evaluated with great enthusiasm to find new lead natural compounds against different diseases. In this review the latest results for new compounds including isolation, biological evaluation, synthetic pathways and some retrosynthetic analyses are summarized.

Advances in Marine Natural Products of the Indole and Annelated Indole Series: Chemical and Biological Aspects

2001

Marine natural products, form a field of scientific endeavour, that has recently grown considerably. The isolation, biological evaluation, chemical properties and synthetic elaborations of products of marine organisms have attracted the attention of organic chemists, medicinal chemists, biologists and pharmacists. In this context a structurally and biologically highly interesting class is represented by the marine natural products containing an indole moiety in a pure substituted form or in an anellated form. The present review summarizes primarily the actual results concerning these products as new pharmacologically attractive lead compounds for drug design. The chemistry, biological evalu…

Fragment- and negative image-based screening of phosphodiesterase 10A inhibitors.

2019

A novel virtual screening methodology called fragment- and negative image-based (F-NiB) screening is introduced and tested experimentally using phosphodiesterase 10A (PDE10A) as a case study. Potent PDE10A-specific small-molecule inhibitors are actively sought after for their antipsychotic and neuroprotective effects. The F-NiB combines features from both fragment-based drug discovery and negative image-based (NIB) screening methodologies to facilitate rational drug discovery. The selected structural parts of protein-bound ligand(s) are seamlessly combined with the negative image of the target's ligand-binding cavity. This cavity- and fragment-based hybrid model, namely its shape and electr…

Las revistas científicas-técnicas españolas de las ciencias de la Actividad Física y el Deporte: inventario y análisis de la calidad de contenido y d…

2003

The first inventory of Spanish scientific journals of Physical Activity and Sport Sciences is developed in this article. Methodological process of inventory development is described and problems related to research group decisions are commented. Basic information and dissemination and content quality indicators of these journals are also analysed. This allows to present the first approach to the current situation of the periodicals in this field of study. En este artículo se presenta el primer inventario de publicaciones periódicas españolas de carácter científico-técnico del campo de las Ciencias de la Actividad Física y el Deporte. Se explica el proceso metodológico seguido para su elabor…
