RESUMO
Introduction of methylene bridges in aegPNA and apgPNA molecules give rise to cyclic five and six membered ring structures. Synthesis of a new six membered cyclic PNA monomer, aminopipecolyl PNA (pipPNA) is reported. Incorporation of pipPNA into PNA oligomers and comparative binding with target DNA sequences is studied.

In the present investigation, the toxicopathological effects of ochratoxin A of 0.5 ppm on hematobiochemical parameters of broilers were studied with efficacy of dietary concentration of probiotic containing yeast culture Saccharomyces boulardii of 10 mg/kg of feed. One hundred twenty day old chicks were randomly divided into four groups, thirty chicks each. Groups A and C chicks were offered normal feed and that added with probiotic Saccharomyces boulardii respectively. The birds in group B were fed ochratoxin A of 0.5 ppm of feed. Where as, the birds of group D, were fed with ochratoxin A of 0.5 ppm along with probiotic Saccharomyces boulardii of 10 mg/kg of diet. Hematological studies carried revealed significant decrease in the haemoglobin and packed cell volume in birds of group B and reduced effect in birds of group D due to probiotic. Biochemical profiles revealed significant improvement in probiotic treated group D when compared with decreased values of Total protein, albumin, globulin and increased levels of serum creatinine and SGPT in birds of groups B.
