1Microscopy Observations of Habitable Space in Biochar for Colonization by Fungal Hyphae From Soil显示文摘Biochar is a potential micro-environment for soil microorganisms but evidence to support this suggestion is limited. We explored imaging techniques to visualize and quantify fungal colonization of habitable spaces in a biochar made from a woody feedstock. In addition to characterization of the biochar, it was necessary to optimize preparation and observation methodologies for examining fungal colonization of the biochar. Biochar surfaces and pores were investigated using several microscopy techniques. Biochar particles were compared in soilless media and after deposition in soil. Scanning electron microscopy(SEM) observations and characterization of the biochar demonstrated structural heterogeneity within and among biochar particles. Fungal colonization in and on biochar particles was observed using light, fluorescence and electron microscopy. Fluorescent brightener RR 2200 was more effective than Calcofluor White as a hyphal stain. Biochar retrieved from soil and observed using fluorescence microscopy exhibited distinct hyphal networks on external biochar surfaces. The extent of hyphal colonization of biochar incubated in soil was much less than for biochar artificially inoculated with fungi in a soilless medium. The location of fungal hyphae was more clearly visible using SEM than with fluorescence microscopy. Observations of biochar particles colonized by hyphae from soil posed a range of difficulties including obstruction by the presence of soil particles on biochar surfaces and inside pores. Extensive hyphal colonization of the surface of the biochar in the soilless medium contrasted with limited hyphal colonization of pores within the biochar. Both visualization and quantification of hyphal colonization of surfaces and pores of biochar were restricted by two-dimensional imaging associated with uneven biochar surfaces and variable biochar pore structure. There was very little colonization of biochar from hyphae in the agricultural soil used in this study.Noraini M Jaafar Peta L Clode Lynette K Abbott 2014Journal of Integrative Agriculture2014,13,3:10
2Soil Microbial Responses to Biochars Varying in Particle Size,Surface and Pore Properties显示文摘Biochars are known for their heterogeneity, especially in pore and surface structure associated with pyrolysis processes and sources of feedstocks. The surface area of biochar is likely to be an important determinant of the extent of soil microbial attachment, whereas the porous structure of biochar is expected to provide protection for soil microorganisms. Potential interactions between biochars from different sources and with different particle sizes were investigated in relation to soil microbial properties in a short-term incubation study. Three particle size(sieved) fractions(0.5–1.0, 1.0–2.0 and 2.0–4.0 mm) from three woody biochars produced from jarrah wood,jarrah and wandoo wood and Australian wattle branches, respectively, were incubated in soil at 25?C for 56 d. Observation by scanning electron microscopy(SEM) and characterisation of pore and surface area showed that all three woody biochars provided potential habitats for soil microorganisms due to their high porosity and surface areas. The biochars were structurally heterogeneous,varying in porosity and surface structure both within and between the biochar sources. After the 56-d incubation, hyphal colonisation was observed on biochar surfaces and in larger biochar pores. Soil clumping occurred on biochar particles, cementing and covering exposed biochar pores. This may have altered surface area and pore availability for microbial colonisation. Transient changes in soil microbial biomass, without a consistent trend, were observed among biochars during the 56-d incubation.Noraini M.JAAFAR Peta L.CLODE Lynette K.ABBOTT 2015Pedosphere2015,25,5:10
3Clinical utility of Epstein-Barr virus DNA and other liquid biopsy markers in nasopharyngeal carcinoma显示文摘Nasopharyngeal carcinoma(NPC)is a malignant epithelial tumor ubiquitously associated with the Epstein-Barr virus(EBV),which is highly prevalent in South China,Southeast Asia,and North Africa.Despite being a highly radio-sensitive and treatable cancer,a majority of NPC patients are diagnosed in their advanced stage,and locoregional and distant relapses following definitive treatment contribute largely to cancer-specific mortality among these patients.Given that EBV-driven NPC is the predominant variant seen in endemic regions,various EBV detection methods have been developed and are utilized in screening,prognostication,and post-treatment surveillance of NPC patients.While the Immunoglobulin A(IgA)serology assay is the most extensively studied EBV detection method,the detection of plasma EBV DNA released during replication or cellular apoptosis has shown superior outcomes in endemic population screening,prognostication,and detection of distant relapse.Furthermore,there is emerging evidence on the use of circulating tumor cells,microRNAs,DNA hypermethylation,and combination assays in various clinical scenarios.Herein,this paper provides a comprehensive overview of the relevant studies using various EBV detection techniques in the management of NPC.Specifically,the recent advances,clinical evidence,and challenges associated with the clinical application of EBV liquid biopsies in population screening,prognostication,and surveillance of NPC are presented.Rong Tan Sean Kean Ann Phua Yoke Lim Soong Lynette Lin Ean Oon Kian Sing Chan Sasidharan Swarnalatha Lucky Jamie Mong Min Han Tan Chwee Ming Lim 2020Cancer Communications2020,40,11:8

7Biochar-Soil Interactions in Four Agricultural Soils显示文摘Soils in south-western Australia are highly weathered and deficient in nutrients for agricultural production. Addition of biochar has been suggested as a mean of improving soil C storage, texture and nutrient retention of these soils. Clay amendment in sandy soils in this region is a management practice used to improve soil conditions, including water repellence. In this study a woody biochar(Simcoa biochar) was characterised using scanning electron microscopy before, and four weeks after, it was incorporated into each of four soils differing in clay content and organic matter. Scanning electron microscopy of Simcoa biochar after incubation in soil showed different degrees of attachment of soil particles to the biochar surfaces after 28 d. In addition, the effects of three biochars, Simcoa biochar, activated biochar and Wundowie biochar, on soil microbial biomass C and soil respiration were investigated in a short-term incubation experiment. It was hypothesised that all three biochars would have greater potential to increase soil microbial activity in the soil that had higher organic matter and clay. After 28-d incubation in soil, all three biochars had led to a higher microbial biomass C in the clayey soil, but prior to this time, less marked differences were observed in microbial biomass C among the four soils following biochar application.Noraini M.JAAFAR Peta L.CLODE Lynette K.ABBOTT 2015Pedosphere2015,25,5:3

9No association between phosphatase and tensin homolog genetic polymorphisms and colon cancer显示文摘AIM: To investigate the association between single nucleotide polymorphisms (SNPs) in the phosphatase and tensin homolog (PTEN) tumor suppressor gene and risk of colon cancer. METHODS: We utilized a population-based casecontrol study of incident colon cancer individuals (n= 421) and controls (n = 483) aged ≥ 30 years to conduct a comprehensive tagSNP association analysis of the PTEN gene. RESULTS: None of the PTEN SNPs were statistically significantly associated with colon cancer when controlled for age, gender, and race, or when additionally adjusted for other known risk factors (P > 0.05). Haplotype analyses similarly showed no association between the PTEN gene and colon cancer. CONCLUSION: Our study does not support PTEN as a colon cancer susceptibility gene.Lynette S Phillips Cheryl L Thompson Alona Merkulova Sarah J Plummer Thomas C Tucker Graham Case Li Li 2009World Journal of Gastroenterology2009,15,30:2
10Oncogene interactions are required for glioma development and progression as revealed by a tissue specific transgenic mouse model显示文摘The aggressive and invasive nature of brain tumors has hampered progress in the design and implementation of efficacious therapies. The recent success of targeted therapies in other tumor types makes this an attractive area for research yet complicating matters is the ability of brain tumors to circumvent the targeted pathways to develop drug resistance. Effective therapies will likely need to target more than one signaling pathway or target multiple nodes within a given pathway. Key to identifying these targets is the elucidation of the driver and passenger molecules within these pathways. Animal models provide a useful tool with many advantages in the study of these pathways. These models provide a means to dissect the critical components of tumorigenesis, as well as serve as agents for preclinical testing. This review focuses on the use of the RCAS/tv-a mouse model of brain tumors and describes their unique ability to provide insight into the role of oncogene cooperation in tumor development and progression.Lynette M.
