Uticaj razliÄitih nivoa ishrane na karakteristike rasta i teksturu mesa duĆŸiÄaste pastrmke (oncorhynchus mykiss wal.)
Eksperiment je realizovan u laboratoriji za akvakulturu Poljoprivrednog fakulteta Univerziteta u Banjoj Luci. Ukupno je naseljeno 100 jedinki u 5 eksperimentalnih grupa, prosjeÄne individualne mase 91.091.37 g, totalne duĆŸine tijela 20.080.10 cm i duĆŸine tijela do raÄve repnog peraja 19.370.10 cm (MSEM). Cilj rada je bio praÄenje efekata razliÄitih nivoa ishrane na karakteristike rasta i teksturu (tvrdoÄu) mesa duĆŸiÄaste pastrmke (Oncorhynchus mykiss). DuĆŸiÄasta pastrmka u svim eksperimentalnim grupama hranjena je istom hranom, sa razliÄitim nivoima ishrane: 20% (G-20) i 10% manje (G-10) u odnosu na standardni nivo ishrane, standardni nivo ishrane (G100) (preporuka proizvoÄaÄa hrane), 10% (G+10) i 20% viĆĄe (G+20) u odnosu na standardni nivo ishrane. StatistiÄki znaÄajna razlika sredina (p<0.05) mase i duĆŸine tijela izmeÄu posmatranih eksperimentalnih grupa javlja se u drugom periodu. Najmanja potrebna sila (kg) za presijecanje mesa duĆŸiÄaste pastrmke konstatovana je na poÄetku eksperimenta kod jedinki prosjeÄne mase oko 90 g. NajtvrÄe meso je kod riba iz eksperimentalnih grupa G+10 i G-10. IzmeÄu posmatranih eksperimentalnih grupa konstatovana je statistiÄki znaÄajna razlika sredina (p<0.05) potrebne sile za presijecanje mesa
Mineralni sastav razliÄitih sorti viĆĄanja (OblaÄinska i Maraska)
Determination of the mineral composition of two varieties of cherries (oblaÄinska i maraska) in their konzumnoj maturity was the aim of this study. The content of individual elements was in mg / 100g: Na (oblaÄinska cherry 4,7 and maraska 5,1), K (195.6 and 211.3), Mg (15.3 and 17.3), Ca (13.1 and 16.4), P (17.1, 18.6) Fe (0.21 and 0.22), Cu (0.08 and 0.09), Zn (0.1 and 0.1) and Mn ( 0.1 and 0.1). Both of these varieties do not represent a significant source of certain elements in the diet, because when consuming 150 grams of fresh cherries relatively well meet the daily needs of the organism is only for potassium and copper.Cilj ovog rada je da se utvrdi mineralni sastav dvije sorte viĆĄanja (oblaÄinska i maraska) u njihovoj konzumnoj zrelosti. SadrĆŸaj pojedinih elemenata iznosio je u mg/100g: Na (oblaÄinska 4,7 i maraska 5,1), K (195,6 i 211,3), Mg (15,3 i 17,3), Ca (13,1 i 16,4), P (17,1 18,6) Fe (0,21 i 0,22), Cu (0,08 i 0,09), Zn (0,1 i 0,1) i Mn (0,1 i 0,1). Obe ove sorte ne predstavljaju znaÄajan izvor pojedinih elemenata u ishrani, jer pri konzumiranju 150 g svjeĆŸih viĆĄanja relativno dobro zadovoljenje dnevnih potreba organizma je samo za kalijum i bakar
Fractional flow reserve of intermediate lesions on collateral donor coronary arteries after myocardial infarction
Fractional flow reserve (FFR) is the gold standard for the functional assessment of coronary arteries. The aim of this study was to evaluate the relation between angiography, QCA and FFR in borderline lesions on collateral donor coronary arteries. In addition, FFR is compared with the angiographic appearance of collaterals to infarction-related arteries and echocardiographically assessed viability of infarct related the LV wall. In 60 patients with previous IM and occluded IRA, functional assessment of borderline coronary stenosis (30-70% DS) on collaterals donor artery was performed. We have not found statistically significant differences in these parameters between groups with different angiographic appearances of collaterals and different viability of distal myocardium. However, we found higher FFR values in diabetic patients (p=0.018). Higher FFR values in diabetic patients reveal the negative effects of diabetes on collateral growth and myocardial viability
SadrĆŸaj mineralnih materija u sremuĆĄu (Allium ursinum) sa razliÄitih lokaliteta Republike Srpske
Allium ursinum is a plant, more known as sremus, crijemus, wild or bearded onion. In nutrition it is used as a vegetable (salad and spice), and in human medicine, as an auxiliary agent. It is significant due to its nutritional and healing value. Since diet is largely used seasonally and in fresh state, as a salad, it can be a significant source of some nutrients, such as mineral matter, which are of great importance for human health. Considering the polemics about sremus as a "source of health" we decided to analyze content of mineral matter, macro and micro elements in sremus, with four different locations of the northwest part of Repulic of Srpska. Sodium concentrations were determined from 31,065 to 32,905 mg / kg, potassium from 4703.06 to 4803.485mg / kg, calcium from 1532.545 to 1559.095 mg / kg. Microelements included nickel (0.358 to 0.388 mg / kg), cobalt, aluminum. Mineral matter was determined by atomic absorption spectrophotometry ICP OES spectroscopy after wet digestion.Allium ursinum u narodu je poznatiji kao sremuĆĄ, crijemuĆĄ, divlji ili medvjeÄi luk. U ishrani se koristi kao povrÄe (salata i zaÄin), a u humanoj medicini kao pomoÄno sredstvo. ZnaÄajan je zbog svoje nutritivne i ljekovite vrijednosti. PoĆĄto se u ishrani najveÄim dijelom koristi sezonski u vrijeme prispjeÄa i u svjeĆŸem stanju, kao salata, moĆŸe da bude znaÄajan izvor pojedinih hranjivih materija, kao npr. mineralnih materija, koje su od velikog znaÄaja za zdravlje ljudi. Obzirom na dosta polemike o sremuĆĄu kao âizvoru zdravljaâ odluÄili smo da u ovom radu analiziramo sadrĆŸaj mineralnih materija, makro i mikro elemenata u sremuĆĄu, sa Äetiri razliÄite lokacije sjeverozapadnog dijela Republike Srpske. OdreÄene su koncentracije natrijuma od 31,065 do 32,905 mgkg-1, kalijuma od 4703,06 do 4803,485mgkg-1, kalcijuma od 1532,545 do 1559,095 mg/kg. Od mikroelemenata odreÄeni su nikl (0,358 do 0,388 mgkg-1), kobalt, aluminijum. Mineralne materije su odreÄivane atomskom apsorpcionom spektrofotometrijom ICP OES spektroskopijom nakon vlaĆŸne digestije

Fractional Flow Reserve Method in Cardiac Catheterization Laboratory without Cardiosurgical Backup: Initial Experiences
Background: Coronary artery disease is the most common cause of death in a modern world. This dictates the development a network of Catheterization laboratories without cardiosurgical capabilities.Aim: We postulate that the most valuable tool in the decision process on myocardial revascularization is fractional flow reserve (FFR), especially when we deal with borderline coronary lesions.Material and Methods: A total of 72 patients with 94 intermediate coronary stenosis (30%-70% diameter reduction) were included in this study. We tested FFR and angiography based decision model on myocardial revascularization.Results: ĂÂ Mean FFR value on left anterior descending coronary artery (LAD) was lower than in others two arteries (p=0.017). FFR after percutaneous coronary intervention (PCI) was significantly better (p<0.0001). The decision for PCI predominates before FFR diagnostics, but after FFR the decision is quite opposite. There is a weak negative correlation between FFR and diameter of stenosis assessed by angiography (r= - 0.245 p=0.038) and positive correlation between diameter of stenosis assessed by angiography and by quantitative coronary angiography (QCA) (r=0.406 p<0.0005).Conclusion: ĂÂ Our results strongly suggest that FFR is necessary tool in centers without possibilities of heart team onsite consultation and that prevents numerous unnecessary PCI
