A method of quantitative comparison of two classi cations rules applied to protein folding problem is presented. Classi cation of proteins based on sequence homology and based on amino acid composition were compared and analyzed according to this approach. The coe cient of correlation between these classi cation methods and the procedure of estimation of robustness of the coe cient are discussed.

We develop a method of calculation for the symplectic Floer homology of composite knots. The symplectic Floer homology of knots defined in [15] naturally admits an integer graded lifting, and it formulates a filtration and induced spectral sequence. Such a spectral sequence converges to the symplectic homology of knots in [15]. We show that there is another spectral sequence which converges to ...

The lipolytic system of Bacillus megaterium 370 was investigated, showing the existence of at least two secreted lipases and a cell-bound esterase. A gene coding for an extracellular lipase was isolated and cloned in Escherichia coli. The cloned enzyme displayed high activity on short to medium chain length (C4^C8) substrates, and poor activity on C18 substrates. On the basis of amino acid sequ...

A method of quantitative comparison of two classifications rules applied to protein folding problem is presented. Classification of proteins based on sequence homology and based on amino acid composition were compared and analyzed according to this approach. The coefficient of correlation between these classification methods and the procedure of estimation of robustness of the coefficient are d...

toxoplasmosis is an infection caused by the protozoan parasite toxoplasma gondii (t.gondii) throughout the world. although usually asymptomatic, the infection can cause serious medical problems in immunocompromised individuals and fetuses. toxoplasmosis also causes considerable economic loss because of abortion in livestock. dna vaccination is a promising approach against intracellular parasite...

objective(s): hypoxia is a serious challenge for treatment of solid tumors. this condition has been manifested to exert significant therapeutic effects on glioblastoma multiform or (who) astrocytoma grade iv. hypoxia contributes numerous changes in cellular mechanisms such as angiogenesis, metastasis and apoptosis evasion. furthermore, in molecular level, hypoxia can cause induction of dna brea...

MOTIVATION Protein sequence alignments have a myriad of applications in bioinformatics, including secondary and tertiary structure prediction, homology modeling, and phylogeny. Unfortunately, all alignment methods make mistakes, and mistakes in alignments often yield mistakes in their application. Thus, a method to identify and remove suspect alignment positions could benefit many areas in prot...
