Systematic review and meta-analysis of interventions tested in animal models of pulmonary hypertension.

A systematic review and meta-analysis was performed to test candidate therapeutic approaches in pulmonary hypertension (PH). The efficacy of 522 interventions with >200 unregistered drugs was tested on 7254 animals. We propose a modified formula to assess meta-data that concerns the contribution of PH animal model to the denoted efficacy of tested agents.

[Current issues in etiology, diagnostics and management in pulmonary hypertension].

Pulmonary hypertension (PH) is a pathophysiological disorder that may involve multiple clinical conditions characterizing with by an abnormal increase in mean pulmonary arterial pressure. It is a rare, debilitating disease with a poor prognosis. Despite significant progress in diagnosis and management, including disease-targeted therapies as well as development of specialized centres, PH remains a chronic disease without a cure.

Animal models of pulmonary arterial hypertension: A systematic review and meta-analysis of data from 6126 animals.

Numerous animal models of pulmonary hypertension are currently available. A systematic review and meta-analysis was performed of a number of experimental studies of disease induction based on several animal models. A meta-analysis was performed of 291 publications discussing the efficacy of 611 interventions to introduce disease pulmonary hypertension in 6126 animals.

Interactions of fish gelatin and chitosan in uncrosslinked and crosslinked with EDC films: FT-IR study.

Films based on fish gelatin, chitosan and blend of fish gelatin and chitosan before and after cross-linking with EDC have been characterized by FT-IR spectroscopy. The FT-IR spectrum of fish gelatin film showed the characteristic amide I, amide II and amide III bands, and the FT-IR spectrum of chitosan film confirmed that the polymer was only a partially deacetylated product, and included CH3-C=O and NH2 groups, the latter both in their free -NH2 and protonated -NH3(+) form. Analysis of FT-IR spectra of two-component, fish gelatin-chitosan film revealed the formation not only of hydrogen bonds within and between chains of polymers, but also of electrostatic interactions between -COO(-) of gelatin and -NH3(+) of chitosan.
