AIM The purpose of this prospective, randomized, controlled study was the comparison of maximal sterile barrier (consisting of mask, cap, sterile gloves, gown, large drape) vs control precautions (mask, cap, sterile gloves, small drape) and of transparent polyurethan film vs gauze dressing for use on central venous (CVC) nontunneled catheters, inserted via the jugular vein. Skin colonization at...

We applied the RFLP approach to identify the cytoplasmic genotypes of selected onion breeding materials from Poland. For this purpose, mitochondrial DNA from cytoplasmic male-sterile (CMS) and male-fertile onions were hybridized with the probes for the following mitochondrial genes: atpA, atp6, atp9, cob, cox1, nad3, nad4 and nad6. S-, T- or C-cytoplasm was represented in each analyzed sterile ...

The capacity of the released sterile males to survive, disperse, compete with wild males and inseminate wild females is an essential prerequisite to be evaluated in any area-wide integrated pest management (AW-IPM) programs including a sterile insect release method. Adequate quality control tests supported by standardized procedures need to be developed to measure these parameters and to identi...

Three cytoplasmic male-sterile Nicotiana cultivars together with corresponding male-fertile progenitors and restored lines were investigated in order to find possible correlations between respiratory characteristics and male sterility. Oxygen consumption measurements were performed on cells from suspension cultures as well as on mitochondria isolated from green leaves. Inhibitors, which have be...

The development of strategies to improve crop plants by the production of hybrid varieties is a major goal in plant breeding. Hybrid progeny often have a higher yield, increased resistance to disease, and an enhanced performance in different environment compared with the parental lines. Availability of cost effective mechanism/ method to produce large scale hybrid seed utilizing selected parent...
