New quality and quantity indices in science (NewQIS): the study protocol of an international project.

Benchmarking systems are important features for the implementation of efficacy in basic and applied sciences. These systems are urgently needed for many fields of science since there is an imbalance present between funding policies and research evaluation. Here, a new approach is presented with an international study project that uses visualisation techniques for benchmarking processes.

Inter-disease comparison of research quantity and quality: bronchial asthma and chronic obstructive pulmonary disease.

Background: The two obstructive airway diseases bronchial asthma and chronic obstructive pulmonary disease (COPD) represent major global causes of disability and death. Whereas COPD research was largely underfunded in the 1980s and 1990s, increased funding activities have been initiated since the year 2000. However, detailed scientometric data on the development of research for asthma and COPD have not been generated so far.

Is TRPV1 a useful target in respiratory diseases?

This review focuses on the transient receptor potential vanilloid 1 (TRPV1). TRPV1 is a non-selective cation channel predominantly expressed in the cell membranes of sensory afferent fibers, which are activated multi-modally. In the mammalian respiratory system, immunohistochemical and electrophysiological studies have revealed heterogeneous localizations of TRPV1 channels in the airways and their presence in pleural afferents.

Interfield dysbalances in research input and output benchmarking: visualisation by density equalizing procedures.

Background: Historical, social and economic reasons can lead to major differences in the allocation of health system resources and research funding. These differences might endanger the progress in diagnostic and therapeutic approaches of socio-economic important diseases. The present study aimed to assess different benchmarking approaches that might be used to analyse these disproportions.

Models of asthma: density-equalizing mapping and output benchmarking.

Despite the large amount of experimental studies already conducted on bronchial asthma, further insights into the molecular basics of the disease are required to establish new therapeutic approaches. As a basis for this research different animal models of asthma have been developed in the past years. However, precise bibliometric data on the use of different models do not exist so far.

The inhibitor of apoptosis (IAP) survivin is expressed in human testicular germ cell tumors and normal testes.

Deregulated apoptosis of germ cells may contribute to malignant transformation as well as male infertility. We analyzed expression of the inhibitor of apoptosis survivin by polymerase chain reaction (PCR) in testicular germ cell tumors (TGCTs, n=28), normal testes (n=19) and testes with defective spermatogenesis (n=22). In a subset of samples (n=35), survivin transcript levels were quantified using real-time PCR.

Neurogenic mechanisms in bronchial inflammatory diseases.

Neurogenic inflammation encompasses the release of neuropeptides from airway nerves leading to inflammatory effects. This neurogenic inflammatory response of the airways can be initiated by exogenous irritants such as cigarette smoke or gases and is characterized by a bi-directional linkage between airway nerves and airway inflammation. The event of neurogenic inflammation may participate in the development and progression of chronic inflammatory airway diseases such as allergic asthma or chronic obstructive pulmonary disease (COPD).
