Comparing natural hydrogels to self-assembling peptides in spinal cord injury treatment: a systematic review
<p><strong>Abstract</strong></p> <p><em><strong>Background:</strong></em><em> </em>In many cases, central nervous system (CNS) injury is unchanging due to the absence of neuronal regeneration and repair capabilities.<strong> </strong>In recent years, regenerative medicine, and especially hydrogels, have reached a significant amount of attention for their promising results for the treatment of spinal cord injury (SCI) currently considered permanent. Hydrogels are categorized based on their foundation: synthetic, natural, and combination. The objective of this study was to compare the properties and efficacy of commonly used hydrogels, like collagen, and other natural peptides with synthetic self-assembling peptide hydrogels in the treatment of SCI. </p> <p><em><strong>Methods</strong></em><em>:</em><em> </em>Articles were searched in PubMed, Scopus, Web of Science, and Embase. All studies from 1985 until January 2020 were included in the primary search. Eligible articles were included based on the following criteria: administering hydrogels (both natural and synthetic) for SCI treatment, soley foucsing on spinal cord injury treatment, and published in a peer-reviewd journal. Data surronding xonal regeneration, revascularization, elasticity, drug delivery efficacy, and porosity were extracted.</p> <p><em><strong>Results:</strong></em> A total of 24 articles were included for full-text review and data extraction. There were only one experimental study directly comparing Collagen I (as natural hydorgel) and PEG (as synthetic hydrogels) in an <em>in vitro </em>setting. The included study suggested PEG’s cell behavior is more expectable in the injury site, which makes it a more reliable scaffold.</p> <p><em><strong>Conclusions:</strong></em> There is limited research comparing and evaluating both types of natural and self-assembling peptides (SAPs) in the same animal or <em>in vitro</em> study, despite its importance. Although we assume that the remodeling of natural scaffolds may lead to a stable hydrogel, there was not a definitive conclusion that synthetic hydrogels are more beneficial than natural hydrogels in neuronal regeneration.</p>

Non-native species drive biotic homogenization, but it depends on the realm, beta diversity facet and study design: A meta-analytic systematic review
<p>While reducing the species richness of invaded communities is a well-known consequence of biological invasions, non-native species can also reduce variability between communities over time (i.e., beta diversity) in a process known as biotic homogenization. Although biotic homogenization due to non-native species is a common topic of theoretical reviews, we believe no global meta-analysis on the effect of non-native species on beta diversity has been carried out yet. Here, we systematically show that non-native species drive biotic homogenization, but it depends on the realm, beta diversity facet and study design. Biotic homogenization was more intense in marine and freshwater ecosystems than in terrestrial ecosystems. We also found that non-native species reduced both taxonomic and phylogenetic beta diversity, but not the functional beta diversity. Finally, we observed more intense effects using "before vs. after invasion" followed by "uninvaded vs. invaded sites" while the effect size of studies using "communities associated with native vs. non-native species" did not differ from zero. Our findings highlight that non-native species contribute to biotic homogenization as a prevalent pattern in communities worldwide, and that biodiversity conservation strategies should go beyond investigating the reduction in the number of species by also taking into account beta diversity in its multiple facets.</p>
