the κ-casein protein plays a fundamental role in milk production and its composition synthesis in the mammary gland. this protein has an important role in the formation, stabilization, and aggregation of the casein micelles. in this study, we investigated the genetic variability at the exon 4 of the κ-casein gene (also known as csn3) using pcr-sscp analysis and dna sequencing. then a protein se...

Quinones are a class of compounds which have widespread importance in chemistry, biology and medicine. Because of their appropriate performance in electron transferring rate, quinones are among the most applicable mediators in biosensors. Recently, the effects of different non-metal substitutions on redox potential of quinone have been investigated to design suitable mediators for different ele...

We consider substitutions on compact alphabets and provide sufficient conditions for the diffraction to be pure point, absolutely continuous singular continuous. This allows one construct examples which Koopman operator associated function space has specific spectral components. For abelian bijective substitutions, we a dichotomy result regarding type of diffraction. also first example substitu...

The intron-exon structure of Khorasan native fowl interleukin-2 (IL-2) was investigated. For this purpose, twenty chickens were selected from the Native Fowl Breeding Station of Khorasan province, and genomic DNA was extracted using a modified conventional DNA extraction protocol. An 875 bp fragment of IL-2 was successfully amplified, including a small part of the promoter, exon 1, intron 1, an...

Plasmodium vivax apical membrane antigen-1(PvAMA-1) is a surface protein with polymorphic sites. This study was aimed to analyze the polymorphic amino acid residues at PvAMA-1 in different infected age groups. 92 blood samples were collected from south and southeast of Iran. The DNA coding for the domain I (DI), DII, and partial DIII of this antigen was amplified by Nested-PCR, and sequenced. N...

objective mitochondrial dna (mtdna) is considered a candidate modifier factor for neuro-degenerative disorders. the most common type of ataxia is friedreich's ataxia (fa). the aim of this study was to investigate different parts of mtdna in 20 iranian fa patients and 80 age-matched controls by polymerase chain reaction (pcr) and automated dna sequencing methods to find any probable point mutati...

background: emergence klebsiella pneumoniae resistant to quinolone antibiotics due to mutations in gyra and parc genes created problem for treatment of patients in different hospitals in iran. the objective of this study was to determine the amino acid substitutions of gyra and parc proteins in certain clonal lineages of the k. pneumoniae conferring high level quinolone resistance. methods: one...

Many competent speakers initially judge that (i) is true and (ii) is false, though they know that (iii) is true. (i) Superman leaps more tall buildings than Clark Kent. (ii) Superman leaps more tall buildings than Superman. (iii) Superman is identical with Clark Kent. Semantic explanations of these intuitions say that (i) and (ii) really can differ in truthvalue. Pragmatic explanations deny thi...

The -calculus [1] adds explicit substitutions to the -calculus so as to provide a theoretical framework within which the implementation of functional programming languages can be studied. This paper generalises the -calculus to provide a linear calculus of explicit substitutions which analogously describes the implementation of linear functional programming languages.
