V našem článku prezentujeme případ podkovovité ledviny s jedním sběrným systémem a jediným zkříženým močovodem a pyelolitiázou. V anglickém jazyce byly dosud celosvětově uveřejněny pouze čtyři publikace popisující případ podkovovité ledviny s jediným zkříženým močovodem. Prezentujeme náš postup při léčbě třicetiletého pacienta s touto vzácně se vyskytující vrozenou malformací a objemnou nefrolitiázou, uvádíme přehled dostupné literatury a nabízíme možná vysvětlení., The present study reports a horseshoe kidney with a single collecting system and a crossed single ureter associated with pyelolythiasis. An association of a crossed single ureter and a horseshoe kidney has only been mentioned in four previous reports in the available English literature worldwide. We present our management of a 30‑year‑old patient with this rare congenital malformation and a large stone burden together with a review of the current available literature and suggest explanation., and Sabler I.

This paper presents a new method for the determination of the volume, surface area and depth of skin defects. The method is based on the description of a spatial defect using a pyramid (made, for example, from injection needles), which is placed over the defect. The projection of the pyramid on to the defect is photographed using a digital camera and subsequently compared with the projection of the same pyramid on to a sheet of grid paper. The defect is mathematically reconstructed on a computer, and an optimal body shape describing the defect is found, using a number of simplifications and assumptions. The method was then validated using a plaster mold of a real foot with 19 defects simulating real wounds. These plaster wounds were molded using alginate hydrocolloid, and the volume, surface area and depth were measured and compared with the results of the pyramid projection by means of regression analysis. This method correlates in all variables with correlation coefficients higher than 0.9. It can be concluded that the projection pyramid method correlates well with the reference mold method and can be used with good results for a whole range of variables., J. Růžička, P. Nový, F.

Etiolated oat mesophyll protoplasts and etioplasts released from etiolated protoplasts were able to perform protochlorophyliide (PChlide) reduction but showed a high amount of inactive P633/628» compared with intact leaves. In špite of this, the anabolic reduction charge (ARC, NAPDH+H+/NADP+ + NADPF1+H+) was maintained at 0.66 - 0.77 up to 30 min of irradiation with weak "white light" (10 W m‘2). This indicated a high buffering capacity of the isolated systém to provide NADPF1+H+, only at the expense of intemal reserves. A change in the redox statě of the NADP+/NADPH+H^ couple during protochlorophyliide reduction was not observed in etioplasts. The resulting redox potential was in the range of -330 mV optimal for protochlorophyliide reduction.
Popisujeme zde unikátní zdroj termického plazmatu s kombinovanou stabilizací obloukového výboje vodním vírem a proudem plynu. Vlastnosti vytvořeného proudu plazmatu, především teplota, obsah energie a průtok plazmatu, jsou podstatně odlišné od vlastností bežně používaných systémů se stabilizací oblouku plynem. Plazmatron byl použti v reaktoru pro plazmovou pyrolýzu a zplynování látek. Proces je využitelný pro produkci syntetického plynu vysoké kvality z odpadní biomasy a organických látek., Milan Hrabovský., and Obsahuje bibliografii
Binding kinetics of some photosystem 2 (PS 2)-directed ínhibitors to isolated pea thylakoids during photoinUbition were studied. Changes in the herbicide binding activity were overshadowed by the redox statě of the plastoquinone (PQ) pool. After extraction of the PQ pool from the thylakoids, a correlation between the decline of herbicide binding activity and the electron transfer activity during strong irradiation was found in the presence of oxygen; in anaerobiosis this correlation was absent. The opposite was observed for the binding kinetics of the electron transfer acceptor 2,6-dichlorophenol indophenol, that was affected faster under anaerobic conditions. Following irradiation, a movement of damaged Dj-protein products from the appressed to the non-appressed regions of the membrane was observed. This observation was correlated to the fínding of an increased level of atrazine bound to the non-appressed regions of irradiated membranes.
