We evaluated the microbiological safety, the short-term storability, and the macronutrients of oil seed cake (OSC) obtained from walnut (WnC), linseed (LC), and sunflower seed with hull (SC). The OSCs had 3.6–5.8% moisture content, 0.50–0.60 water activity (aw), 29.9–39.4% protein, 15.5–23.6% fat, and 36.6–48.0% dietary fibre content. The grinded OSCs could be stored in opaque plastic bags for 4 months at temperatures of 4 °C, 14 °C, and 25 °C. Total colony count of mesophilic microorganisms depending on oxygen demand and spore-forming ability, and faecal indicator microorganisms were determined during a 4-month storage term at 4 °C, 14 °C, and 25 °C using traditional culturing methods. The OSCs were free from sulphite-reducing Clostridia and coliforms, including Escherichia coli. Data were analyzed statistically by multifactor analysis of variance. Ascending order of the average contamination of the three products (log10 CFU g−1) was aerobic sporogenic bacteria (2.39), fungal count (2.51), total aerobic microbe count (3.00), anerobic sporogenic bacteria (3.75), and total anaerobic microbe count (4.23). As for the average microbial count, WnC was the least (2.73 log10 CFU g−1) and LC was the highest (3.53 log10 CFU g−1) contaminated material. Regarding the variation of microbial contamination during storage, temperature was indifferent (P=0.191), while storage time (P=0.0033) and the product type were influential (P=0.000).

The surface flavonoid distributions of 20 samples of 12 Salvia species originating from Hungary or Bulgaria were surveyed. The majority of the flavonoids proved to be flavones. The most common constituents of the exudates were apigenin, luteolin and scutellarein 6,7,4'-trimethyl ether (salvigenin). Flavonols were found only in S. ringens. No significant variation in flavonoid profile was observed between the samples with different origins. The flowers of the plants studied were richer than the leaves and stems in flavonoids.

The nutritive value, the microbiological safety of oilseed cake (OSC) obtained from naked pumpkin seed (PuC), sunflower seed (SC), yellow linseed (LC), and walnut (WnC), and their impact on wheat flour (WF) dough and bread sensory characteristics at 5% and 10% addition ratio were investigated. The OSCs had high protein (34–50%), fat (8–15%), total dietary fibre (23–36%) content and high energy value (383–444 kcal/100 g)). The OSC samples with a minimal exception fulfilled the requirements of feed legislation in force. An increased water absorption, dough development time, and reduced elasticity were observed probably due to the enhanced fiber and protein content. Dough stability increased with WnC, and decreased with PuC or SC addition. Enrichment provided the appearance of a brown bread for WnC, of a half-brown bread for LC. PuC gave an unusual look. The appearance of OSC fortified bread similar to daily bread, was an advantage resulting the 1st rank for 10% WnC bread and the 2nd one for 10% LC bread (P=0.05). The studied OSCs are suitable for food enrichment, however, in case of PuC and SC fortified flour blends, hydrocolloid application is recommended. Our data suggest that the newly developed fortified breads could be a valuable source for healthy nutrition.

Hepatic artery complication represents recognized sequel of liver transplantation that carries significant morbidity and mortality. Besides retransplantation, hepatic artery recanalization is provided surgically, or by percutaneous angioplasty and stent placement. This study provides an analysis of a single center experience comparing surgical and interventional treatments in cases of early hepatic artery complications.
In this retrospective single center study, 25 of 365 liver transplant recipients were enrolled who developed early hepatic artery complication after transplantation. Percutaneous intervention was performed in 10 cases, while surgical therapy in 15 cases. Mean follow-up time was not different between the groups (505±377 vs. 706±940 days, respectively).
6 patients in the Intervention Group and 10 patients in the Surgery Group are alive. The retransplantation rate (1 and 3) was lower after interventional procedures, while the development of biliary complications was higher. The mortality rate was higher after operative treatment (2 and 5).
Interventional therapy is a feasible and safe technique for treatment of early hepatic artery complication after transplantation. Being less invasive it is an invaluable alternative treatment having results comparable to surgical methods.
