BACKGROUND Benign vocal fold lesions, including cysts, nodules, polyps, and Reinke's edema, are common causes of hoarseness and subsequent voice disorders. Given the prevalence of these lesions, disease etiology and pathophysiology remain unclear and their microbiota has not been studied to date secondary to the paucity of available biopsies for investigation. We sought to characterize and comp...

The wetlands of the Qinghai-Tibetan Plateau are believed to play an important role in global nutrient cycling, but the composition and diversity of microorganisms in this ecosystem are poorly characterized. An understanding of the effects of geography and microtopography on microbial populations will provide clues to the underlying mechanisms that structure microbial communities. In this study,...

Island plants are frequently used as model systems in evolutionary biology to understand factors that might explain genetic diversity and population differentiation levels. Theory suggests that island plants should have lower levels of genetic diversity than their continental relatives, but this hypothesis has been rejected in several recent studies. In the Azores, the population level genetic ...

Current knowledge of the microbial composition of dental plaque in early gingivitis is based largely on microscopy and cultural methods, which do not provide a comprehensive description of oral microbial communities. This study used 454-pyrosequencing of the V1-V3 region of 16S rRNA genes (approximately 500 bp), and bacterial culture, to characterize the composition of plaque during the transit...

BACKGROUND Canine idiopathic inflammatory bowel disease (IBD) is believed to be caused by a complex interaction of genetic, immunologic, and microbial factors. While mucosa-associated bacteria have been implicated in the pathogenesis of canine IBD, detailed studies investigating the enteric microbiota using deep sequencing techniques are lacking. The objective of this study was to evaluate muco...

The impacts of leaf litter from genetically modified hybrid poplar accumulating high levels of condensed tannins (proanthocyanidins) were examined in soil microcosms consisting of moss growing on sieved soil. Moss preferentially proliferated in microcosms with lower tannin content; DGGE (denaturing gradient gel electrophoresis) detected increased fungal diversity in microcosms with low-tannin l...

Different studies have reported a narrow genetic base for garden asparagus (Asparagus officinalis L.) due to its common origin, diploid population (‘Purple Dutch’). The present study focused on the development of new plant material that may be useful widen crop by using tetraploid landrace ‘Morado de Huétor’ (A. × A. maritimus). With this purpose, pre-breeding (n = 1000) carrying introgressions...

Capirona (Calycophyllum spruceanum Benth.) is a tree species of commercial importance widely distributed in South American forests that traditionally used for its medicinal properties and wood quality. Studies on this have been focused mainly properties, propagation, growth. However, genetic studies capirona very limited to date. Currently, it possible explore diversity population structure fas...

Aims : To describe the compositional and ecological diversity of Mulgedio-Aconitetea communities in Sudetes Mts. their foothills. Study area The (Southwestern Poland). Methods A total 399 vegetation relevés from own field studies literature were sorted into groups that match higher syntaxa EuroVegChecklist associations described literature. Diagnostic species so delimited determined with phi-co...

ABSTRACT Grape and cherry mini tomatoes have been conquering Brazilian consumers due to their sweet taste, practicality of consumption, versatility in culinary use. Therefore, the present work aimed characterize ten grape tomato hybrids based on genetic diversity physical biochemical traits provide information for development new genotypes focused appearance enrichment nutritional factors.
