Novel breads fortified through oilseed and nut cakes

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

Development of clinical simultaneous SPECT/MRI

There is increasing clinical use of combined positron emission tomography (PET) and magnetic resonance imaging (MRI) but to date there has been no clinical system developed capable of simultaneous single photon emission computed tomography (SPECT) and MRI. There has been development of preclinical systems, but there are several challenges faced by researchers who are developing a clinical prototype including the need for the system to be compact and stationary with MRI-compatible components. The limited work in this area is described with specific reference to the Integrated SPECT/MRI for Enhanced stratification in Radio-chemo Therapy (INSERT) project, which is at an advanced stage of developing a clinical prototype. Issues of SPECT/MRI compatibility are outlined and the clinical appeal of such a system is discussed, especially in the management of brain tumour treatment

Classification of mesic grasslands and their transitions of South Transdanubia (Hungary)

Relevés from meadows and pastures of South Transdanubia (Hungary) are evaluated by clustering and ordination methods. The relevé selection focused on the Arrhenatheretalia order but its transitions towards other types were also included. The groups of relevés are delimited and described according to differential, dominant and constant species. Ecological conditions of the groups were compared using indicator values. Nine groups were distinguished, four of them belonging strictly to the order Arrhenatheretalia. Each alliance of Arrhenatheretalia presented in the study area (Cynosurion, Arrhenatherion) was represented by two groups. Groups from these two alliances are separated along a light gradient, while groups of the same alliance differ in nutrient values. Within Cynosurion, the nutrient-poor group cannot be identified unambiguously as any syntaxa previously known from Hungary. The nutrient-rich Cynosurion meadows are similar to Lolio–Cynosuretum, however, they show a stronger relationship with wet meadows. Within Arrhenatherion, Pastinaco–Arrhenatheretum is recognised as a hay meadow of nutrient-rich soils. The other meadow type is similar to Filipendulo–Arrhenatheretum, thus raising syntaxonomical problems. There are transitional groups towards semi-dry and wet meadows, one dynamic phase and one outlier group among the other five clusters

Evaluation of Brain Nuclear Medicine Imaging Tracers in a Murine Model of Sepsis-Associated Encephalopathy

PURPOSE: The purpose of this study was to evaluate a set of widely used nuclear medicine imaging agents as possible methods to study the early effects of systemic inflammation on the living brain in a mouse model of sepsis-associated encephalopathy (SAE). The lipopolysaccharide (LPS)-induced murine systemic inflammation model was selected as a model of SAE. PROCEDURES: C57BL/6 mice were used. A multimodal imaging protocol was carried out on each animal 4 h following the intravenous administration of LPS using the following tracers: [(99m)Tc][2,2-dimethyl-3-[(3E)-3-oxidoiminobutan-2-yl]azanidylpropyl]-[(3E)-3-hyd roxyiminobutan-2-yl]azanide ([(99m)Tc]HMPAO) and ethyl-7-[(125)I]iodo-5-methyl-6-oxo-4H-imidazo[1,5-a][1,4]benzodiazepine-3-carbox ylate ([(125)I]iomazenil) to measure brain perfusion and neuronal damage, respectively; 2-deoxy-2-[(18)F]fluoro-D-glucose ([(18)F]FDG) to measure cerebral glucose uptake. We assessed microglia activity on another group of mice using 2-[6-chloro-2-(4-[(125)I]iodophenyl)-imidazo[1,2-a]pyridin-3-yl]-N-ethyl-N-methyl -acetamide ([(125)I]CLINME). Radiotracer uptakes were measured in different brain regions and correlated. Microglia activity was also assessed using immunohistochemistry. Brain glutathione levels were measured to investigate oxidative stress. RESULTS: Significantly reduced perfusion values and significantly enhanced [(18)F]FDG and [(125)I]CLINME uptake was measured in the LPS-treated group. Following perfusion compensation, enhanced [(125)I]iomazenil uptake was measured in the LPS-treated group's hippocampus and cerebellum. In this group, both [(18)F]FDG and [(125)I]iomazenil uptake showed highly negative correlation to perfusion measured with ([(99m)Tc]HMPAO uptake in all brain regions. No significant differences were detected in brain glutathione levels between the groups. The CD45 and P2Y12 double-labeling immunohistochemistry showed widespread microglia activation in the LPS-treated group. CONCLUSIONS: Our results suggest that [(125)I]CLINME and [(99m)Tc]HMPAO SPECT can be used to detect microglia activation and brain hypoperfusion, respectively, in the early phase (4 h post injection) of systemic inflammation. We suspect that the enhancement of [(18)F]FDG and [(125)I]iomazenil uptake in the LPS-treated group does not necessarily reflect neural hypermetabolism and the lack of neuronal damage. They are most likely caused by processes emerging during neuroinflammation, e.g., microglia activation and/or immune cell infiltration

Successful islet after kidney transplantations in a distance over 1000 kilometres: Preliminary results of the Budapest-Geneva collaboration

To overcome critical islet processing and to ensure patient safety and quality care, we have established an international collaboration between two geographically distant transplant centers for islet transplantation. Four pancreata were harvested and immediately preserved by the two-layer method (oxygenated perfluorocarbon+University of Wisconsin) and subsequently transported for the automated method isolation to Geneva. After purification, the islets were cultured overnight and transported the next day back to Budapest. Three consecutive kidney transplant patients with type 1 diabetes mellitus underwent islet transplantation via percutaneous transhepatic portal embolization using the bag-method. The immunosuppression consisted of daclizumab, sirolimus, and low-dose tacrolimus. Mean donor age was 43.7 years, mean body mass index: 26.5. The islet isolation process began within 8 hours from the donor aorta cross-clamp in all cases. The isolation success rate was 80% (4 of 5). In Budapest, the islets were assessed for viability. No complications occurred during the transplantation, and the portal pressure remained within the normal range. The first patient received 12,000 IU/BW from two donors and the insulin requirement decreased from 40 U/d to 10 U/d. The second patient received 7200 IU/BW from a single donor and became immediately insulin free. The third patient was given 7100 IU/BW; the insulin requirement decreased from 39 U/d to 14 U/d. Posttransplant follow-up for the three patients are 7 months, 4 months, and 2 weeks, respectively. All patients achieved metabolic stability. These preliminary results demonstrate the feasibility of an international collaborative islet transplantation program at a distance over 1000 km
