“Bioinformatics” 특집을 내면서

Impatti, adattamento e vulnerabilita Le cause e le responsabilita dei cambiamenti climatici sono state trattate sul numero di ottobre della rivista Cda. Approfondiamo l’argomento presentando il documento: “Cambiamenti climatici 2007: impatti, adattamento e vulnerabilita” votato ad aprile 2007 dal secondo gruppo di lavoro del Comitato Intergovernativo sui Cambiamenti Climatici (Intergovernmental Panel on Climate Change). Si tratta del secondo di tre documenti che compongono il quarto rapporto sui cambiamenti climatici.

Climate Change 2007: Impacts, Adaptation and Vulnerability.

Since the beginning, medical practitioners and veterinarians have employed a vast variety of antimicrobials to treat microbial infectious diseases that were based primarily on past clinical experiences. However, the emergence of resistance among microbial species against traditionally used antimicrobials has made it more difficult for clinicians to empirically select an appropriate antimicrobial agent. As a result, global concern has been deviated toward finding the efficacy of available antimicrobials. Therefore, it is recommended to validate already existing in vitro antimicrobial susceptibility testing (AST) methods. Although a variety of methods exist, the goal of AST is to provide a reliable predictor of how an organism is likely to respond to antimicrobial therapy in the infected host. The selection of a particular AST method is based on many factors such as validation data, practicality, flexibility, automation, cost, reproducibility, accuracy, and individual preference. In the modern methodologies, use of genotypic approaches for detection of antimicrobial resistance genes has also been promoted as a way to increase the speed and accuracy of susceptibility testing. Many DNA-based assays are being developed to detect bacterial antibiotic resistance at the genetic level. These methods, when used in conjunction with phenotypic analysis, offer the promise of increased sensitivity, specificity, and speed in the detection of specific known resistance genes and can be used in tandem with traditional laboratory AST methods. The invention of new molecular technologies in genomics and proteomics is shifting traditional techniques for bacterial classification, identification, and characterization in the twenty-first century toward methods based on the elucidation of specific gene sequences or molecular components of a cell. The new methods can be rapid, offer high throughput, and produce unprecedented levels of discrimination among strains of bacteria and archaea.

Conventional culture-based techniques are imperative in investigating the microbial ecology of natural and anthropogenically impacted environments, but they are tremendously prejudiced and unfair in their evaluation of microbial genetic assortment by selecting a specific inhabitant of microbes. Due to current progresses in genomics and sequencing methodologies, microbial community studies using culture nondependent molecular procedures have begun a new epoch of microbial ecology. Molecular studies of ecological communities have discovered that cultivable microbial segment represents <1 % of whole number of prokaryotic species existing in any sample. Various molecular approaches based on direct isolation and analysis of genetic material, proteins, and lipids from ecological samples have been discovered and shown the structural and functional information about microbial groups. Novel molecular tactics such as genetic fingerprinting, metagenomics, metaproteomics, metatranscriptomics, and proteogenomics are imperative and essential for determining and describing the huge microbial variety along with understanding of their synergistic behavior with biotic and abiotic ecological factors. This chapter recapitulates the latest development in molecular microbial ecology area paying attention to new methods and tactics that suggest novel understandings into phylogenetic, practical, and functional assortment of microbial assemblages. The benefits and drawbacks of normally employed molecular techniques to investigate microbial structures are also discussed along with probable applications of novel molecular approaches and how they can provide a outlook on developing technologies for environmental microbial community profiling.

Omics: Tools for Assessing Environmental Microbial Diversity and Composition

Plant calreticulins (CRTs) are ubiquitously expressed and are similar to animal CRTs in structural organization and basic functioning. Its expression is affected by developmental and environmental stimuli showing its role in the physiology of plants. Though it is an important member of the Ca2+ homeostasis of the endoplasmic reticulum, the underlying mechanism of growth modulation by CRT is still unclear and is an area of recent research.
