The effects of afforestation on soil bacterial communities in temperate grassland are modulated by soil chemical properties
PeerJ - Tập 7 - Trang e6147
Shuhong Wu, Bing Huang, Jian Gao, Siqi Wang, Pei‐Chun Liao
Grassland afforestation dramatically affects the abiotic, biotic, and ecological function properties of the original ecosystems. Interference from afforestation might disrupt the stasis of soil physicochemical properties and the dynamic balance of microbiota. Some studies have suggested low sensitivity of soil properties and bacterial community to afforestation, but the apparent lack of a ...... hiện toàn bộ
CTLA-4 polymorphisms associate with breast cancer susceptibility in Asians: a meta-analysis
PeerJ - Tập 5 - Trang e2815
Zhiming Dai, Tian Tian, Meng Wang, Xinghan Liu, Shuai Lin, Pengtao Yang, Kang Liu, Yi Zheng, Peng Xu, Meng Liu, Xuewen Yang, Zhijun Dai
Previous studies have investigated the association between cytotoxic T-lymphocyte antigen-4 (CTLA-4) polymorphisms and breast cancer susceptibility, but the results remained inconsistent. Therefore, we evaluated the relationship between four common CTLA-4 polymorphisms and breast cancer risk by a meta-analysis, aiming to derive a compre...... hiện toàn bộ

Effect of dark sweet cherry powder consumption on the gut microbiota, short-chain fatty acids, and biomarkers of gut health in obese db/db mice
PeerJ - Tập 6 - Trang e4195
José F. García-Mazcorro, Nara Nunes Lage, Susanne U. Mertens‐Talcott, Stephen T. Talcott, Boon P. Chew, Scot E. Dowd, Jorge R. Kawas, Giuliana Noratto
Cherries are fruits containing fiber and bioactive compounds (e.g., polyphenolics) with the potential of helping patients with diabetes and weight disorders, a phenomenon likely related to changes in the complex host-microbiota milieu. The objective of this study was to investigate the effect of cherry supplementation on the gut bacterial composition, concentrations of caecal short-chain f...... hiện toàn bộ
Leopard (Panthera pardus) status, distribution, and the research efforts across its range
PeerJ - Tập 4 - Trang e1974
Andrew P. Jacobson, Peter Gerngross, Joseph Lemeris, Rebecca F. Schoonover, Corey Anco, Christine Breitenmoser‐Würsten, Sarah M. Durant, Mohammad S. Farhadinia, Philipp Henschel, Jan F. Kamler, Alice Laguardia, Susana Rostro‐García, Andrew Stein, Luke Dollar
The leopard’s (Panthera pardus) broad geographic range, remarkable adaptability, and secretive nature have contributed to a misconception that this species might not be severely threatened across its range. We find that not only are several subspecies and regional populations critically endangered but also the overall range loss is greater than the average for te...... hiện toàn bộ
Survey of owner motivations and veterinary input of owners feeding diets containing raw animal products
PeerJ - Tập 5 - Trang e3031
Stewart K. Morgan, Susan Willis, Megan Shepherd
BackgroundThe practice of feeding of diets containing raw animal products (RAP) to pets (dogs and cats) is discouraged by veterinary organizations and governmental public health organizations. Nevertheless, the practice of feeding RAP to pets is increasing in popularity. Pet owner motivations for feeding RAP diets to pets have not been explored and the be...... hiện toàn bộ
De novo clustering methods outperform reference-based methods for assigning 16S rRNA gene sequences to operational taxonomic units
PeerJ - Tập 3 - Trang e1487
Sarah L. Westcott, Patrick D. Schloss
Background.16S rRNA gene sequences are routinely assigned to operational taxonomic units (OTUs) that are then used to analyze complex microbial communities. A number of methods have been employed to carry out the assignment of 16S rRNA gene sequences to OTUs leading to confusion over which method is optimal. A recent study suggested that a clustering method should be...... hiện toàn bộ
Detection of stable community structures within gut microbiota co-occurrence networks from different human populations
PeerJ - Tập 6 - Trang e4303
Matthew Jackson, Marc Jan Bonder, Zhana Kuncheva, Jonas Zierer, Jingyuan Fu, Alexander Kurilshikov, Cisca Wijmenga, Alexandra Zhernakova, Jordana T. Bell, Tim D. Spector, Claire J. Steves
Microbes in the gut microbiome form sub-communities based on shared niche specialisations and specific interactions between individual taxa. The inter-microbial relationships that define these communities can be inferred from the co-occurrence of taxa across multiple samples. Here, we present an approach to identify comparable communities within different gut microbiota co-occurrence netwo...... hiện toàn bộ
GMPR: A robust normalization method for zero-inflated count data with application to microbiome sequencing data
PeerJ - Tập 6 - Trang e4600
Li Chen, James Reeve, Lujun Zhang, Nancy Y. Ip, Xuefeng Wang, Jun Chen
Normalization is the first critical step in microbiome sequencing data analysis used to account for variable library sizes. Current RNA-Seq based normalization methods that have been adapted for microbiome data fail to consider the unique characteristics of microbiome data, which contain a vast number of zeros due to the physical absence or under-sampling of the microbes. Normalization met...... hiện toàn bộ
Mammals from ‘down under’: a multi-gene species-level phylogeny of marsupial mammals (Mammalia, Metatheria)
