BACKGROUND Patients with oligoasthenoteratozoospermia (OAT) and normal karyotypes have an increased sperm aneuploidy rate. This may be due to an altered intratesticular environment that affects the chromosomal segregation mechanism(s). Alternatively, it may be due to a generalized meiotic and mitotic abnormality. In this case, patients with abnormal spermatogenesis should also have an increased...

The study "Alexander" on bacterial resistance to antibiotics conducted in Poland revealed high sensitivity of bacterial strains to simple and cheap antibiotics. In Poland pharmacoeconomic studies on the safety, effectiveness and costs of treatment are rare. Development of therapeutic standards in bacterial infections on the basis of pharmacoeconomic analyses and clinical studies determining eff...

background and purpose: an important factor involved in infertility is reactive oxygen species (ros). ros can damage sperm dna, and involve lipid per-oxidation. ros elevation is under the influence of leukocyte activation. the objective of this study was to evaluate the level of ros as well as leukocyte, in normozoospermic (no) and ologoasthenoteratozoospermic (oat) ejaculates. materials and me...

in order to study of nitrogen absorb and use efficiency of wheat (triticum aestivum) and wild oat (avena fatua) at vegetative growth stage, a factorial experiment was conducted based on completely randomized block design with three replications in research greenhouse of faculty of agriculture, at ferdowsi university of mashhad in 2008. the first factor was competition between wild oat (densitie...

effect of different planting ratios of oat (avena sativa l.) and vetch (vicia sativa l.) was assessed on quality and quantity of forage and silage in an intercropping system as completely randomized block design (rcbd) with four replications. the treatments were different planting ratios of oat and vetch including 0:100, 20:80, 40:60, 50:50, 60:40, 80:20 and 100:0 (oat-vetch) formed as replacem...

In the current study, macro and microelement contents of oat grains were determined by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). P contents of grains were found between 2428.72 mg/kg (Arslanbey) and 4557.25 mg/kg (TL10). While K contents of oat samples change between 3055.99 mg/kg (TL63) and 5621.12 mg/kg (TL8), Ca contents of oats ranged from 568.50 mg/kg (TL63) to...

molecular experiment was conducted to confirm resistant to aryloxyphenoxypropionate herbicides in winter wild oat (avena ludoviciana duriu.) populations of wheat fields in khuzestan province, at faculty of agriculture of ferdowsi university, during year of 2006. first, 44 wild oat populations from ahvaz, andimeshk, shush, shushtar, ramhormoz, susangerd, and dezful cities with a susceptible popu...
