    Suprachoroidal hemorrhage is a rare and potentially devastating clinical entity seen in individuals on anticoagulation presenting with severe unilateral eye pain, sudden vision loss, and elevated intraocular pressures. Herein, we report the first case of aseptic orbital cellulitis caused by recurrent spontaneous suprachoroidal hemorrhage. This case highlights an example of non-infectious orbital cellulitis arising from choroidal pathology in the setting of uncontrolled intraocular pressures and recurrent intraocular bleeding. Surgical intervention with blood drainage should be considered to prevent complications and preserve the globe

    Efficiency of different methods and forms of microelements application in function of n fertilizer in apple trees

    In order to achieve a high yield and quality of apple fruit, more effective ways of fertilization are required in the modern, high density apple orchards. The objective of this research was to determine the efficiency (partial nutrient balance, PNB) of different methods (foliar and fertrigation) and forms (chelates and salts) of microelements application in relation to the levels of N fertilization in apple orchard cultivar (‘Golden Delicious’). The combined effects of these fertilizers on the number of apple fruits per tree and on the yield per tree were also studied. Foliar application of Mn, Zn and Fe had significantly higher partial nutrient balance values compared to the soil application in both years of the experiment. However, most of the PNB values were below 10% indicating relatively low efficiency of the applied fertilizers with microelements

    Wpływ kwasu naftenowego (NAS) na reakcję jabłoni ‘Golden Delicious’ i ‘Fuji’ na chemiczne przerzedzanie za pomocą NAA

    NAA (α-naphthylacetic acid) thins apple fruits inconsistently regarding fruit set and weight and may cause small or misshapen fruits occurrence. Considering hormonal activity, surfactant properties and the impact of naphthenic acids (NAs) on the metabolism of auxins in plant tissue, it is assumed that thinning response and fruit size could be improved by adding NAs to NAA for chemical thinning of apple. The purpose of the research was to evaluate thinning efficacy of the mixture of NAA and NAs in two commercially grown apple cultivars, ‘Golden Delicious’ and ‘Fuji’, known to respond differently to the application of NAA. The following treatments were applied during a three-year period, from 2010 to 2012: 10 mg∙L-1 NAA, 10 mg∙L-1 NAA + 1.56 mg∙L-1 NAs, 20 mg∙L-1 NAA, 20 mg∙L-1 NAA + 3.12 mg∙L-1 NAs and an untreated control. The addition of NAs to NAA did not alter the effectiveness of NAA in reducing fruit set, while it significantly increased fruit weight compared to NAA applied alone in two of three years of the experiment. NAs modulated the effect of NAA on fruit weight of apple cultivar ‘Fuji’ by retarding fruit growth and causing a higher number of small fruits to occur compared to NAA applied alone.NAA (kwas naftylooctowy) nierównomiernie przerzedza owoce jabłoni jeśli chodzi o zawiązki i masę oraz może spowodować małe i źle uformowane owoce. Odnosząc się do działania hormonalnego, właściwości substancji powierzchniowo czynnych oraz wpływu kwasu naftenowego (Nas) na metabolizm auksyn w tkance roślinnej, to zakłada się, że reakcję na przerzedzanie oraz rozmiar można polepszyć poprzez dodanie NAs do NAA do chemicznego przerzedzania jabłek. Celem badania była ocena skuteczności przerzedzania mieszaniny NAA i NAs u dwóch komercyjnie hodowanych odmian jabłoni: ‘Golden Delicious’ oraz ‘Fuji’, o których wiadomo, że reagują różnie na zastosowanie NAA. Zastosowano następujące zabiegi podczas 3-letniego okresu badań (2010– 2012): 10 mg∙L-1 NAA, 10 mg∙L-1 NAA + 1,56 mg∙L-1 NAs, 20 mg∙L-1 NAA, 20 mg∙L-1 NAA + 3,12 mg∙L-1 NAs oraz kontrola bez zabiegów. Dodatek NAs do NAA nie zmienił skuteczności NAA w zmniejszaniu zawiązków, natomiast istotnie zwiększył masę owoców w porównaniu z zastosowaniem samego NAA w dwóch z trzech lat doświadczenia. NAs regulował wpływ NAA na masę owoców odmiany ‘Fuji’ poprzez opóźnianie wzrostu owoców i podwyższenie liczby małych owoców w porównaniu z zastosowaniem samego NAA
