Mestastatic prostate cancer cells (MPCCs) frequently metastasize to bone, which is a “favorite soil” for colonization and proliferation of MPCCs. Prostate cancer bone mestastasis is tightly associated with tumor-induced bone lesions, most commonly caused from the etiological imbalance between osteoblastic bone formation and osteoclastic bone resorption, and from the anti-tumor immune response. ...
Background: Synthetic biology is an interdisciplinary branch of biology and engineering. As synthetic biology develops into a promising science and engineering field, we need to clarify the purpose and nature of this science in terms of security, ethics and the recognition of the benefits of potential risks. The aim of this study was to evaluate the researchers’ attitudes toward synthetic biolo...
The understanding of soil behavior during the last 300 years has centered on mechanical principles, geological processes, and later on, mineralogy and the relevance of colloidal chemistry. More recently, research in biology and earth science has enabled important advances in understanding the crucial involvement of microorganisms in the evolution of the earth, their ubiquitous presence in near ...
to date there is not progress commercially production and large scale application of pgpr in agriculture. one reason for limited commercial use of pgpr is variability, inconsistency and irreproduciblility of results between laboratory, greenhouse, and field trials. these problems with pgpr arises from variation in crops and cultivars, the physical, chemical and biological composition of soils,...
The use of fertilizers containing heavy metals repeatedly and in the long term can lead to accumulation soil, while functional microbes are used improve fertilization efficiency, fertility soil health. This study aims determine content number found vermicompost agricultural soil. research begins with manufacture worms that feed a mixture chicken manure, banana weevil tofu dregs. had been taken ...
Characterization of hydric soils and the relationship between soil oxidation-reduction processes and wetland plant distribution are critical to the identification and delineation of wetlands and to our understanding of soil processes and plant functioning in wetland ecosystems. However, the information on the relationship between flood response of wetland plants and reducing soil conditions is ...
BACKGROUND Burkholderia pseudomallei is a soil saprophytic bacterium that causes melioidosis. The infection occurs through cutaneous inoculation, inhalation or ingestion. Bacteriophages (phages) in the same ecosystem may significantly impact the biology of this bacterium in the environment, and in their culturability in the laboratory. METHODS/PRINCIPAL FINDINGS The soil samples were analysed...
Climate and litter quality are primary drivers of terrestrial decomposition and, based on evidence from multisite experiments at regional and global scales, are universally factored into global decomposition models. In contrast, soil animals are considered key regulators of decomposition at local scales but their role at larger scales is unresolved. Soil animals are consequently excluded from g...
We tested for soil substrate effects on the movement and infectivity of naturally co-occurring entomopathogenic nematodes Steinernema feltiae and Heterorhabditis marelatus, alone and in combination. We manipulated the presence and bulk density of soil and added Galleria mellonella baits within capped and perforated 15mL centrifuge tubes. Sampling tubes were then deployed in situ into field and ...
