Abstract: Sorta Buga je že dolgo razširjena na območju Istre, tako da jo pojmujemo kot domačo sorto. Sorta Buga je v prvih letih počasnejše rasti, v polni rodnosti pa je šibka do srednje bujna, z lepo, gosto krošnjo. Za dobro rodnost potrebuje opraševalne sorte, čeprav je v posameznih letih zaznati boljšo samooploditev od ostalih domačih sort in udomačenih sort z izjemo sorte Istrska belica. Značilna zanjo je izmenična rodnost.

Abstract: Sorta 'Itrana' se uporablja za pridelavo olja kot za pripravo namiznih oljk. Za sorto sta značilna hitra rast in dobro ukoreninjenje. Sorta ima zbito in pokončno krošnjo. Za oploditev potrebuje opraševalne sorte, ki so 'Leccino', 'Pendolino' in 'Olivastro'. Sorta ima delno izmenično rodnost. Olje vsebuje srednje veliko tokoferolov in biofenolov ter velik delež oleinske kisline. Dobro prenaša nizke temperature. Občutljiva je za napad oljčne muhe, neobčutljiva pa za pavje oko.

Abstract: Sorta 'Drobnica' je bila dobro zastopana v Slovenski Istri do pozebe leta 1956. Po pozebi jo je nadomestila sorta 'Istrska belica'. Za sorto 'Drobnica' je bila ugotovljena znotrajsortna raznolikost, saj so bili ugotovljeni štirje različni genotipi. Drevo je srednje bujno in pokončne rasti. Za sorto so značilni kratki, ozki in drobni listi. Za dobro oploditev potrebuje opraševalne sorte, ki trenutno še niso znane. Plodovi neenakomerno dozorevajo. Olje vsebuje srednje veliko biofenolov in tokoferolov. Sorta je malo občutljiva na oljčno muho in nizke temperature, občutljiva pa je na pavje oko in oljčnega molja.

Abstract: Olives affected by active and damaging infestation (olive fruit fly Bactrocera oleae (Rossi)) were assayed for their chemical composition. Biophenols were determined by HPLC, sterols, triterpenic dialcohols, and fatty acids by gas chromatography analysis. The acquired data were statistically analyzed. Oils produced from "Istrska belica" fruit affected by active infestation compared to the oils made from fruit affected by damaging infestation showed higher amounts of total oleuropein biofenols (377.3 versus (vs.) 106.6 mg/kg), total biophenols (755 vs. 377 mg/kg), lignans (85.3 vs. 32.9mg/kg), the dialdehydic formof decarboxymethyl oleuropein aglycone (DMO-AgldA) (148.3 vs. 49.0 mg/kg), its oxidized form (DMO-Agl-dA)ox (35.2 vs. 8.5 mg/kg), the dialdehydic form of oleuropein aglycone (O-Agl-dA) (61.1 vs. 8.0 mg/kg), the dialdehydic form of ligstroside aglycone (L-Agl-dA) (63.5 vs. 28.0 mg/kg), the aldehydic form of oleuropein aglycone (O-Agl-A) (40.6 vs. 8.4 mg/kg), and lower amounts of tyrosol (Tyr) (6.0 vs. 13. 9 mg/kg) and the aldehydic form of ligstroside aglycone (L-Agl-A) (13.8 vs. 40.3 mg/kg). Higher values of stigmasterol (2.99%) and lower values of campesterol (2.25%) were determined in oils affected by damaging infestation; an increase in triterpenic dialcohols was also observed (3.04% for damaging and 1.62% for active infestation). Oils affected by damaging infestation, compared to active infestation, showed lower amounts of oleic acid (73.89 vs. 75.15%) and higher amounts of myristic (0.013 vs. 0.011%), linoleic (7.27 vs. 6.48%), and linolenic (0.74 vs. 0.61%) acids.

Abstract: Background: Urine output is widely used as one of the criteria for the diagnosis and staging of acute renal failure, but few studies have specifically assessed the role of oliguria as a marker of acute renal failure or outcomes in general intensive care unit (ICU) patients. Using a large multinational database, we therefore evaluated the occurrence of oliguria (defined as a urine output < 0.5 ml/kg/h) in acutely ill patients and its association with the need for renal replacement therapy (RRT) and outcome. Methods: International observational study. All adult (> 16 years) patients in the ICON audit who had a urine output measurement on the day of admission were included. To investigate the association between oliguria and mortality, we used a multilevel analysis. Results: Of the 8292 patients included, 2050 (24.7%) were oliguric during the first 24 h of admission. Patients with oliguria on admission who had at least one additional 24-h urine output recorded during their ICU stay (n = 1349) were divided into three groups: transient-oliguria resolved within 48 h after the admission day (n = 390 [28.9%]), prolonged-oliguria resolved > 48 h after the admission day (n = 141 [10.5%]), and permanent-oliguria persisting for the whole ICU stay or again present at the end of the ICU stay (n = 818 [60.6%]). ICU and hospital mortality rates were higher in patients with oliguria than in those without, except for patients with transient oliguria who had significantly lower mortality rates than non-oliguric patients. In multilevel analysis, the need for RRT was associated with a significantly higher risk of death (OR = 1.51 [95% CI 1.19%1.91], p = 0.001), but the presence of oliguria on admission was not (OR = 1.14 [95% CI 0.97%1.34], p = 0.103). Conclusions: Oliguria is common in ICU patients and may have a relatively benign nature if only transient. The duration of oliguria and need for RRT are associated with worse outcome.
