Molecular knowledge regarding the primary esophageal achalasia is essential for the early diagnosis and treatment of this neurodegenerative motility disorder. Therefore, there is a need to find the main microRNAs (miRNAs) contributing to the mechanisms of achalasia. This study was conducted to determine some patterns of deregulated miRNAs in achalasia. This case-control study was performed on 52 patients with achalasia and 50 nonachalasia controls. The miRNA expression profiling was conducted on the esophageal tissue samples using the next-generation sequencing (NGS).

In this study, we used traditional methods to isolate and screen for fungal laccases that have potential for use in the textile industry (dye decolorization) and a molecular marker to identify studied samples. Fifteen strains of basidiomycetes were isolated and screened for laccase activities on phenol, guaiacol and RBBR. Five strains showed positive laccase activities on all three substrates.

Understanding the genetic complexity of traits is an important objective of small grain temperate cereals yield and adaptation improvements. Bi-parental quantitative trait loci (QTL) linkage mapping is a powerful method to identify genetic regions that co-segregate in the trait of interest within the research population. However, recently, association or linkage disequilibrium (LD) mapping using a genome-wide association study (GWAS) became an approach for unraveling the molecular genetic basis underlying the natural phenotypic variation.

In this paper the individual markers (COI and 18S rRNA) were successfully used to identify some sponge taxa at the species level. The obtained results showed the congruence of molecular taxonomy using two independent markers. However, our study showed that a combination of the two markers provided more information and supported better for sponge identification.

Diagnostic tests by molecular biology is made for studying the relations among Fusarium species for linking production of proteins, degree of relationship and occurrence of malformation. Determination of proteins for isolates causing-disease by SDS-PAGE explained there’s specific band for each fungus and there are common bands among some isolates of fungi. Since, band with MW 30 KDa represented only in F. proliferatum and F. oxysporum and F. subgluti-nans respectively. This band considered as specific band for these isolates, which released high patho-genisity effect.

Glucose transporters (GLUTs) have been implicated in adaptive and survival responses to hypoxic stress in mam-mals. In fish, the expression and regulation ofGLUT in relation to hypoxia remains unexplored. Here we describe the identification ofa hypoxia-responsive glucose transpor-ter gene (gcGLUT) and the corresponding full-length cDNA from the grass carp. The gene spans
11 kb ofgenomic sequence and consists of12 exons and 11 introns, and an open reading frame (ORF) of 1599 bp encoding a poly-peptide of533 amino acids, with a predictedmolecularmass of
57 kDa and a pI of8.34....

As a first step toward developing a zebrafish model for investigating the role of sulfation in counteracting environ-mental estrogenic chemicals, we have embarked on the identification and characterization of cytosolic sulfotrans-ferases (STs) in zebrafish. By searching the zebrafish expressed sequence tag database, we have identified two cDNA clones encoding putative cytosolic STs. These two zebrafish ST cDNAs were isolated and subjected to nuc-leotide sequencing. Sequence data revealed that the two zebrafishSTs are highlyhomologous, being
82%identical in their amino acid sequences....

Numerous adhesion molecules have been described, and the molecular mechanisms of lymphocyte trafficking across the endothelium is starting to be elucidated. Identification of the molecules involved in the organoselec-tivity of this process would help in the targeting of drug therapy to specific tissues. Adhesion-regulating molecule-1 (ARM-1) is an adhesion-regulating molecule previously identified on T cells. It does not belong to any known families of adhesion molecules.

We report here the identification of a tachykinin-related peptide (TRP) in crustaceans. Direct MALDI-TOF MS withbrainslicesof the crayfishProcambarus clarkiiindicated the presence of a peptide having an MS number of around 934. Quadrupole orthogonal acceleration time-of-flight (Q-TOF) MS/MS analysis implied the sequence to be APSGFLGMRamide, identical to that of CabTRP Ia, isolated previously from the crab Cancer borealis,and Pev-tachykinin, from the shrimpPenaeus vannamei.

Reliable detection and identification of pathogens in complex biological samples, in the presence of contaminating DNA from a variety of sources, is an important and challenging diagnostic problem for the development of field tests. The problem is compounded by the difficulty of finding a single, unique genomic sequence that is present simultaneously in all genomes of a species of closely related pathogens and absent in the genomes of the host or the organisms that contribute to the sample background. ...
