A taxonomic reassessment of the genus from China.

Molecular analysis of the genus was conducted with ITS and 28S sequences available, including newly gained sequences from Chinese specimens. Combined with the morphological examinations, a new hypogeous species, was described and illustrated from North China, which is morphologically characterized by reddish brown ascomata covered with fine warts, the whitish gleba with numerous small chambers, 3-5 layers peridium with reddish brown polygonal cells and the smooth and regular ellipsoid ascospores with one large oil drop. Two species previously described as were transferred to .

The efficacy of intravenous aminocaproic acid in primary total hip and knee arthroplasty: a meta-analysis.

Background: We conducted a meta-analysis from randomized controlled trials (RCTs) and non-RCTs to assess the efficacy of aminocaproic acid in cases of primary total hip arthroplasty (THA) or total knee arthroplasty (TKA).

Methods: Potentially relevant academic articles were identified from the Cochrane Library, MEDLINE (1966-2017 October 31), PubMed (1966-2017 October 31), EMBASE (1980-2017 October 31), and ScienceDirect (1985-2017 October 31). Secondary sources were identified from the references of the included literature.

Molecular analysis of Chinese truffles resembling Tuber californicum in morphology reveals a rich pattern of species diversity with emphasis on four new species.

In China the species name Tuber californicum is assigned to pale truffles in the genus Tuber that have more or less regularly globose ascospores; however, we recently discovered that the name was misapplied to some specimens collected in China. In the present study we re-examined all available Chinese collections purported to be T. californicum, including herbarium specimens and newly collected materials, with morphological and molecular methods.

Phylogenetic analyses of Chinese Tuber species that resemble T. borchii reveal the existence of the new species T. hubeiense and T. wumengense.

In phylogenetic analyses based on the internal transcribed spacers and 28S nuc rDNA and translation elongation factor 1-α to compare Chinese white truffle specimens that have ascomata resembling the European Tuber borchii, the sequences of Chinese species resembling T. borchii in morphology grouped into seven distinct clusters among three clades: Puberulum, Maculatum and Latisporum No sequences from these Chinese species matched those of the European T. borchii and the occurrence of the European T.
