genus acomys comprising 14 species from mouse like rodents and substituted in murinae subfamily. the aim of this research was surveying external, cranial and dental character differences among diverse populations of acomys dimidiatus in minab, boushehr and geno biosphere reserve. sampling was performed during summer 2003 and 2005. total of 52 species were collected from mentioned sites. the res...

Blue mussels (Mytilus trossulus) were transplanted in cages for three months in two Swedish coastal areas in the Bothnian Sea (northern Baltic Sea) to investigate the interactions between analysed environmental chemicals and biological responses. A wide array of biological parameters (biomarkers) including antioxidant and biotransformation activity, geno-, cyto- and neurotoxic effects, phagocyt...

INTRODUCTION Environmental exposure to harmful chemicals may produce severe consequences. AIM The aim of the authors was to perform geno- and immune-toxicological monitoring in female employees occupationally exposed to cytostatic agents in hospitals and compare the findings to those obtained from controls. METHOD Altogether 642 women working in hospital who were occupationally exposed to c...

The first reports about pterygium date back to Hippocrates, and this disease still threatens vision health around the world. Pterygium is a formation of fibrous tissue consisting of highly vascularized epithelial and subepithelial tissue that grows excessively and with an abnormal shape on the cornea. Many physical and biological factors are associated with the pathogenesis of pterygium, includ...

People are exposed to an ever-increasing number of chemical compounds that are developed by industry for a wide range of applications. These compounds may harmfully react with different cellular components and activate specific defense mechanisms that provide protection against the toxic, mutagenic, and possibly oncogenic consequences of exposure. Monitoring the activation of specific cellular ...

Bradyrhizobium sp. LMTR 3 is a representative strain of one of the geno(species) of diazotrophic symbionts associated with Lima bean (Phaseolus lunatus) in Peru. Its 7.83 Mb genome was sequenced using the Illumina technology and found to encode a complete set of genes required for nodulation and nitrogen fixation, and additional genes putatively involved in root colonization. Its draft genome s...

Multiplex-PCR assay for identification of Klebsiella pneumoniae isolates carrying gene clusters for biosynthesis of capsular polysaccharide (CPS) types K1 and K2 was developed. Genes wzc and orf10 of the cps cluster were applied as K1 and K2 specific markers respectively. The assay specificity was confirmed using 147 isolates of Klebsiella spp. including 77 K-antigen reference strains. The mult...

Antibiotic resistance is a global threat to human health, wherefore it is crucial to study the mechanisms of antibiotic resistance as well as its emergence and dissemination. One way to analyze the acquisition of de novo mutations conferring antibiotic resistance is adaptive laboratory evolution. However, various evolution methods exist that utilize different population sizes, selection strengt...

Motivation: We present a new technique to recognize remote protein homologies relies on combining probabilistic modeling and supervised learning in high-dimensional feature spaces. The main novelty of our technique is the method of constructing feature vectors using Hidden Markov Model and the combination of this representation with a classifier capable of learning in very sparse high-dimension...

The genetic code of amino acid sequences in proteins does not allow understanding and modeling of inherited processes such as inborn coordinated motions of living bodies, innate principles of sensory information processing, quasi-holographic properties, etc. To be able to model these phenomena, the concept of geno-logical coding, which is connected with logical functions and Boolean algebra, is...
