Project description:To effectively monitor microbial populations in acidic environments and bioleaching systems, a comprehensive 50-mer-based oligonucleotide microarray was developed based on most of the known genes associated with the acidophiles. This array contained 1,072 probes in which there were 571 related to 16S rRNA and 501 related to functional genes. Acid mine drainage (AMD) presents numerous problems to the aquatic life and surrounding ecosystems. However, little is known about the geographic distribution, diversity, composition, structure and function of AMD microbial communities. In this study, we analyzed the geographic distribution of AMD microbial communities from twenty sites using restriction fragment length polymorphism (RFLP) analysis of 16S rRNA genes, and the results showed that AMD microbial communities were geographically distributed and had high variations among different sites. Then an AMD-specific microarray was used to further analyze nine AMD microbial communities, and showed that those nine AMD microbial communities had high variations measured by the number of detected genes, overlapping genes between samples, unique genes, and diversity indices. Statistical analyses indicated that the concentrations of Fe, S, Ca, Mg, Zn, Cu and pH had strong impacts on both phylogenetic and functional diversity, composition, and structure of AMD microbial communities. This study provides insights into our understanding of the geographic distribution, diversity, composition, structure and functional potential of AMD microbial communities and key environmental factors shaping them. This study investigated the geographic distribution of Acid Mine Drainages microbial communities using a 16S rRNA gene-based RFLP method and the diversity, composition and structure of AMD microbial communities phylogenetically and functionally using an AMD-specific microarray which contained 1,072 probes ( 571 related to 16S rRNA and 501 related to functional genes). The functional genes in the microarray were involved in carbon metabolism (158), nitrogen metabolism (72), sulfur metabolism (39), iron metabolism (68), DNA replication and repair (97), metal-resistance (27), membrane-relate gene (16), transposon (13) and IST sequence (11).

Project description:The post-mortem interval (PMI) is the time that elapses since the death of an individual until the body is found. Different molecules have been analyzed to better estimate the PMI with variable results. The miRNAs draw attention in the forensic field to estimate the PMI, since they can better support degradation. To find potential biomarkers for PMI estimation, we analyzed the miRNome at early PMI in rat skeletal muscle using the Affymetrix GeneChip™ miRNA 4.0 micoarrays. In this dataset, we include the expression of 1218 rat miRNAs at early postmortem interval.

Project description:To determine what can the transcriptome tell us about populations of free-ranging bottlenose dolphins, Tursiops truncatus. Keywords: health assessment A total of 151 individuals were sampled from 4 different geographic location in U.S. waters between June of 2003 and June of 2006. Of the 151 dolphins, 59 were from Charleston, 35 from Indian River Lagoon, FL, 32 from Sarasota Bay, FL and 25 from St. Josephs Bay FL. Total RNA extracted from blood leukocytes of wild dolphins was analyzed and different sets of genes were used as classifiers in a machine learning approach, Artificial Neural Networks (ANN).

Project description:The pathophysiological mechanism(s) underlying PMI remain controversial. Small non-coding molecules that modulate gene expression may enhance the detection of myocardial injury and provide further mechanistic insight. We profiled plasma exosomal microRNA in patients who sustained PMI after elective non-cardiac surgery

Project description:Bone is a long-lasting biological tissue often used in forensic investigations as it retains vital biomolecular information commonly used for identification purposes. Bone proteins have attracted interest for their potential in estimating post-mortem interval (PMI) and age-at-death (AAD). However, the preservation of such proteins is highly dependent on intrinsic and extrinsic factors, and these have an impact in the potential application of molecular techniques to forensic sciences. The present study aims at investigating the effect that two commonly used types of burial practices (entombment and inhumation) have on bone protein survival. The sample consists in 14 exhumed individuals from cemeteries in south of Italy at with different AADs (29-85 yeas) and PMIs (1-37 years). LC-MS/MS analyses show that 16 proteins are better preserved in the entombed condition and four in the inhumated one, while no clear cluster separation is detected with principal component analysis. Besides the different burial environments, several potential protein markers are identified for PMI and AAD estimation. Overall, preliminary results show that the two burial environments seem to play a marginal role in the differential preservation of non-collagenous proteins and in the accumulation of post-translational modifications, confirming the potential of LC-MS/MS based proteomics in forensic sciences.
