The effect of N-allyl -N ́-2-pyridyl-thiourea and γ-irradiation on growth, yield and quality of peas and wheat have been studied. The γ-irradiation of peas with 10000 R led to an increase in yield of green mass and grain of peas and treatment with 15000R led to a decrease of yield. These changes also correlate with the protein content in the green mass and(More)
Morbidity and Mortality meetings are an accepted tool for quality management in many hospitals. However, it is not proven whether these meetings increase quality. It was the aim of this study to investigate whether Morbidity and Mortality meetings as part of a PDCA cycle (Plan, Do, Check, Act) can improve the rate of anastomotic failure in colorectal(More)
Ultrastructural morphometric examinations of changes in myocardial cells of two groups of patients were carried out before and after cardioplegic ischaemia. The ACB group (aorto-coronary bypass) comprised patients suffering from chronic The ACB group (aorto-coronary bypass) comprised patients suffering from chronic ischaemic heart disease, whilst the AVR(More)
The effect of 12 derivatives of N-phenyl-N'-aryl- or alkylthiourea, inhibitors of human enteroviruses and foot-and-mouth disease virus, on reproduction of some rhinoviruses (H-17, B-632) in HeLa Bristol cells was studied. As screening methods both the multicylce growth test in roller tube cultures and two variants of plaque inhibition tests were employed.(More)
Inhibition of potato virus X replication can be enhanced by complexation of N-allyl-N'-2-pyridyl-thiourea and of N-phenyl-N'-2-pyridyl-thiourea with Cu+, Zn2+ and Cd2+. The antiphytoviral activity of some complexes with pyridylthiourea can be further augmented by adding small quantities of 2,4-dioxohexahydro-1,3,5-triazine.
The cytokinin activity of a group of derivatives of N-n-butyl-N′-arylthiourea and their effect on the uptake of amino acids and the accumulation of total nitrogen in seven-day barley seedlings have been investigated. It was established that N-n-butyl-N″-2,4-dinitrophenyl-thiosemicarbazide, N-n-butyl-N′-o-,m- andp-chlorophonylthioureas,(More)
BACKGROUND Bariatric surgery is proven to be the most effective therapy for obesity. However, the targeted weight reduction is not always achieved. Reliable predictors for postoperative success are rare. Also, most available predictors, such as gender and socioeconomic status, cannot be influenced. The aim of the study was to assess the reliability of the(More)
The synthesis of the new radioprotective compounds ATB (I, 2-allylthioureidobenzoic acid), PTB (II, 2-phenylthioureidobenzoic acid), A-2-PTU (III, N-allyl-N"-2-pyridylthiourea), and P-2-PTU (IV, N-phenyl-N"-2-pyridylthiourea) and their influence on biological and genetic effects of gamma rays was studied. In result of investigations it must be noted that(More)
