The synthesis and characterization of a resorcinarene-based tetra(imidazole) ligand is reported. The properties of the corresponding ZnII complex are studied in depth, notably by NMR spectroscopy. In MeCN, acid-base titration reveals that one out of the four imidazole arms is hemi-labile and can be selectively protonated, thereby opening a coordination site in the exo position. Quite remarkably, the 4th imidazole arm promotes binding of an acidic molecule (a carboxylic acid, a β-diketone or acetamide), by acting as an internal base, which allows guest binding as an anion to the metal center in the endo position...

Single nucleotide polymorphisms (SNPs) are the main type of variation in genome, enabling them to be associated with traits of economic importance in livestock. Genome-wide association studies (GWAS) have led to the discovery of SNPs associated with desirable traits in sheep. However, in these studies, SNPs are genotyped by high-throughput methods in genome scale, which are expensive and require sophisticated equipment and analysis methods. Therefore, the goal of this study was to develop a reliable, rapid, and inexpensive polymerase chain reaction (PCR)-based method to genotype a medium number of animals for a few candidate SNPs previously associated with desirable phenotypes in sheep by GWAS, using markers associated with gastrointestinal nematode resistance as a model...

Infertility occurs in 10-15% of couples worldwide and close to half of it is caused by male factors. One of the genes that can affect male infertility is CGA. Polymorphisms in CGA gene may affect gene expression, therefore affecting male infertility by disrupting the regulation of this gene. One of the polymorphisms is the substitution of T with A in the miR-1302 binding site in the 3' untranslated region of the CGA gene. In this study, we explored this polymorphism in Isfahan population. In this case-control study, by the use of Tetra primer-ARMS-PCR technique, rs6631 has been investigated in 224 infertile men and 196 controls...

Complex N-glycans of glycoproteins of the zona pellucida (ZP) of human oocytes have been implicated in the binding of spermatozoa. The termini of these unusual bi-, tri-, and tetra-antennary N-glycans consist of the tetrasaccharide sialyl-Lewisx (SLex ), which was previously identified as the minimal epitope for sperm binding. We describe here the chemoenzymatic synthesis of highly complex triantennary N-glycans derived from ZP carrying SLex moieties at the C-2 and C-2' arm and a sialyl-Lewisx -Lewisx (SLex -Lex ) residue at the C-6 antenna and two closely related analogues...

The tetra-primer ARMS-PCR is a rapid, simple and low cost method for single nucleotide polymorphism (SNP) genotyping and has been used to detect SNPs associated with diseases and drug resistance. E198A in the isotype-1 β-tubulin gene is one of the three SNPs associated with benzimidazole resistance in parasitic nematode Haemonchus contortus. However, up to now, only PCR-RFLP method was used to test E198A in H. contortus. In the present study, we developed a tetra-primer ARMS-PCR to detect E198A in H. contortus and the accuracy of the results was compared with that of PCR-coupled sequencing...

It was established that 2-O-benzoyl-3,4,6-tri-O-benzyl protected β-SEt, β-SPh and β-SBox glucosyl donors are not superarmed when using the NIS/TfOH promoter system, but instead have a similar reactivity as their classically armed tetra-O-benzyl protected glucosyl counterparts. The β-SBox 2-O-benzoyl-3,4,6-tri-O-benzyl glucosyl donor, however, was found to be superarmed under DMTST activation. Our studies have shown that the increased reactivity of the β-SBox 2-O-benzoyl-3,4,6-tri-O-benzyl glucosyl donor with DMTST activation could be a unique case, and that the high reactivity of glucosyl donors with the 2-O-benzoyl-3,4,6-tri-O-benzyl protection pattern is not general as earlier suggested...
