Fermented and unfermented brown macroalgae as partial salt replacers in sodium-reduced dough and bread

Bread can be a major contributor to sodium intake, but sodium chloride reduction poses difficulties since it influences the functional properties of dough and flavor of bread. This study evaluated dough and bread properties in reduced-sodium systems containing fermented or unfermented macroalgae Saccharina latissima or Alaria esculenta. Recipes contained equal amounts of sodium (4 mg Na+/g flour), where sodium chloride contributed 3 or 3.5 mg Na+/g flour and 8.9–33.3 mg macroalgae/g flour contributed the remaining 0.5 or 1 mg Na+/g flour. A full-salt and three salt-reduced controls (6, 4, 3.5, and 3 mg Na+/g flour) were used for comparison. Empirical dough rheology, stickiness, ratios of polymeric to monomeric proteins, and bread characteristics (specific volume, crumb structure, and firmness) were measured. A trained sensory panel conducted a descriptive sensory analysis. Macroalgae addition increased water absorption and decreased dough development time, dough stability, the polymeric to monomeric protein ratio, and specific volume in a dose-dependent manner. Macroalgae addition increased the perception of saltiness, but also algae flavor and odor. Bread with fermented S. latissima received lower scores for certain undesirable sensory attributes than other bread with algae.publishedVersio

Correlation between Targeted qPCR Assays and Untargeted DNA Shotgun Metagenomic Sequencing for Assessing the Fecal Microbiota in Dogs

DNA shotgun sequencing is an untargeted approach for identifying changes in relative abundances, while qPCR allows reproducible quantification of specific bacteria. The canine dysbiosis index (DI) assesses the canine fecal microbiota by using a mathematical algorithm based on qPCR results. We evaluated the correlation between qPCR and shotgun sequencing using fecal samples from 296 dogs with different clinical phenotypes. While significant correlations were found between qPCR and sequencing, certain taxa were only detectable by qPCR and not by sequencing. Based on sequencing, less than 2% of bacterial species (17/1190) were consistently present in all healthy dogs (n = 76). Dogs with an abnormal DI had lower alpha-diversity compared to dogs with normal DI. Increases in the DI correctly predicted the gradual shifts in microbiota observed by sequencing: minor changes (R = 0.19, DI 2, DI > 5, and DI > 8, respectively), compared to dogs with a normal DI (DI < 0, all targets within the RI), as higher R-values indicated larger dissimilarities. In conclusion, the qPCR-based DI is an effective indicator of overall microbiota shifts observed by shotgun sequencing in dogs

Coumarin anticoagulants and co-trimoxazole: avoid the combination rather than manage the interaction

OBJECTIVE: The objective of our study was to examine the management of the interaction between acenocoumarol or phenprocoumon and several antibiotics by anticoagulation clinics and to compare the consequences of this interaction on users of co-trimoxazole with those for users of other antibiotics. METHODS: A follow-up study was conducted at four anticoagulation clinics in The Netherlands. Data on measurements of the International Normalised Ratio (INR), application of a preventive dose reduction (PDR) of the coumarin anticoagulant, fever and time within or outside the therapeutic INR range were collected. RESULTS: The study cohort consisted of 326 subjects. A PDR was given more often to users of co-trimoxazole PDR than to users of other antibiotics. The PDR in co-trimoxazole users resulted in a significantly reduced risk of both moderate overanticoagulation (INR >4.5) and severe overanticoagulation (INR >6.0) compared with no PDR, with odds ratios (ORs) of 0.06 [95% confidence interval (CI): 0.01-0.51] and 0.09 (95% CI: 0.01-0.92), respectively. In co-trimoxazole users without PDR, the risk of overanticoagulation was significantly increased compared with users of other antibiotics. All co-trimoxazole users spent significantly more time under the therapeutic INR range during the first 6 weeks after the course than users of other antibiotics. CONCLUSION: PDR is effective in preventing overanticoagulation in co-trimoxazole users, but results in a significantly prolonged period of underanticoagulation after the course. Avoidance of concomitant use of co-trimoxazole with acenocoumarol or phenprocoumon seems to be a safer approach than management of the interaction between these drugs

Defining the causes of sporadic Parkinson's disease in the global Parkinson's genetics program (GP2)

The Global Parkinson’s Genetics Program (GP2) will genotype over 150,000 participants from around the world, and integrate genetic and clinical data for use in large-scale analyses to dramatically expand our understanding of the genetic architecture of PD. This report details the workflow for cohort integration into the complex arm of GP2, and together with our outline of the monogenic hub in a companion paper, provides a generalizable blueprint for establishing large scale collaborative research consortia

Multi-ancestry genome-wide association meta-analysis of Parkinson?s disease

Although over 90 independent risk variants have been identified for Parkinson’s disease using genome-wide association studies, most studies have been performed in just one population at a time. Here we performed a large-scale multi-ancestry meta-analysis of Parkinson’s disease with 49,049 cases, 18,785 proxy cases and 2,458,063 controls including individuals of European, East Asian, Latin American and African ancestry. In a meta-analysis, we identified 78 independent genome-wide significant loci, including 12 potentially novel loci (MTF2, PIK3CA, ADD1, SYBU, IRS2, USP8, PIGL, FASN, MYLK2, USP25, EP300 and PPP6R2) and fine-mapped 6 putative causal variants at 6 known PD loci. By combining our results with publicly available eQTL data, we identified 25 putative risk genes in these novel loci whose expression is associated with PD risk. This work lays the groundwork for future efforts aimed at identifying PD loci in non-European populations

Vergleichende klinische und immunhistochemische Charakterisierung keratozystischer odontogener Tumoren und Ameloblastome im Hinblck auf das Rezidivverhalten

Hintergrund: Die �Keratozyste� rückt mit der neuen Bezeichnung keratozystischer odontogener Tumor� (KZOT) auch in der Nomenklatur näher an die differentialdiagnostisch relevante Entität der Ameloblastome (A). Fragestellung: Das Rezidivverhalten von KZOT und Ameloblastomen wird vor dem Hintergrund etablierter Therapieverfahren und immunhistochemischer Marker des Zellzyklus und der Migration oder Strukturumbildung in einer retrospektiven Analyse miteinander verglichen. Patienten und Methoden: Klinische und immunhistochemische Untersuchung von 103 Patienten (88 x KZOT, 15 x Ameloblastome) über einen Zeitraum von 22 Jahren. Histologie: In Paraffin eingebettete chirurgische Bioptate wurden in Multiblocktechnik arrangiert und mit den monoklonalen Antikörpern Cyclin D1, Kollagen IV, p16, Cox-2, Laminin-5, Tenascin-C immunhistochemisch gefärbt. Ergebnisse: Altersdurchschnitt: KZOT 47 Jahre (14-80 Jahre), Ameloblastome 41 Jahre (16-79 Jahre). Geschlechtsverteilung: KZOT: m:w=2:1, Ameloblastome: m:w=3:2. Lokalisation: Im Unterkiefer mit Prädilektionsstelle in der Molarenregion und im aufsteigenden Unterkierferast fanden sich 76 KZOT und 12 Ameloblastome, im Oberkiefer 18 KZOT und 3 Ameloblastome. Multiples Auftreten nur bei 5 KZOT-Patienten. Therapie: Bei primären KZOT: 6 x Zystostomie, 48 x Zystektomie, 17 x Zystektomie und Kürettage, 14 x Zystektomie und marginale Ostektomie, 11 x Resektion. Bei Ameloblastomen: 5 x Enukleation, 10 x Resektion. Rezidivrate: Für KZOT ergab sich eine Rezidivrate von 11,7% nach durchschnittlich 5,4 Jahren, dabei 4 Rezidive nach Zystostomie, 6 nach Zystektomie, 3 nach Zystektomie und Kürettage und 2 nach Zystektomie und marginaler Ostektomie. Bei den Ameloblastomen trat kein Rezidiv auf. Immunhistochemie: Sowohl die Zellzyklus assoziierten als auch die extrazellulären Matrixproteine unterschieden bezüglich ihrer Quantität weder KZOT von den Ameloblastomen noch rezidivierende von nicht rezidivierenden KZOT. Schlussfolgerungen: 1. Die KZOT zeigen im eigenen Untersuchungsgut mehr Rezidive als die Ameloblastome. 2. Das höhere Rezidivverhalten der KZOT kann nicht durch die üblichen Marker des Zellzyklus und der Migration oder Strukturmodulation erklärt werden. 3. Die ungünstige Prognose der KZOT im Vergleich zu den Ameloblastomen im eigenen Untersuchungsgut wird durch eine eingeschränkte Radikalität der Therapie und durch das Auftreten charakteristischer Satellitenzysten erklärt

Att göra kön på ungdomsgårdar : en kvalitativ studie

The purpose of this essay is to describe and analyze how three leisure centers in Örebro county are working with gender issues. Our research questions are: What is Machofabriken? How do leisure centers in Örebro county work with equal treatment? In which way do leisure centers in Örebro county work with Machofabriken’s material? How come the recreation centers in Örebro don’t use Machofabriken’s material to any greater extent? We have focused on masculinity oriented gender projects at three leisure centers. We did semi-structured interviews with three recreation leaders who have all been educated in Machofabriken. The interviews were analyzed based on terms that are central in gender equality and masculinity research. The result demonstrates how they work with gender equality, how they use Machofabriken’s material and their thoughts and opinions about the material.Syftet med denna uppsats är att beskriva och analysera hur tre fritidsgårdar i Örebro kommun arbetar med jämställdhet. Våra frågeställningar är: Vad är Machofabriken? Hur ser jämställdhetsarbetet ut på fritidsgårdar i Örebro kommun? På vilket sätt arbetar fritidsgårdar med Machofabrikens material? Varför används inte Machofabrikens material i någon större utsträckning på fritidsgårdarna i Örebro? Vi har fokuserat på tre fritidsgårdars jämställdhetsarbete, framförallt det riktat mot unga män. Vi har utgått från semistrukturerade intervjuer med tre fritidsledare som alla har gått en utbildning i Machofabriken. Intervjuerna är analyserade utifrån begrepp som är centrala inom jämställdhets- och maskulinitetsforskning. Resultatet visar hur de arbetar med jämställdhet, hur de använder Machofabrikens material och deras tankar och åsikter om materialet

Untersuchungen zu Sequenzvarianten im p12-Gen beim hereditären Pankreaskarzinom

Unter allen Karzinomen rangiert das Pankreaskarzinom in Deutschland bei Männern an fünfter und bei Frauen an sechster Position. Die schlechte Prognose mit einer 5-Jahres-Überlebensrate von etwa 4% resultiert aus einer meist späten Diagnose der Erkrankung mit oft schon bestehenden Metastasen und begrenzten Therapiemöglichkeiten. Das Pankreaskarzinom tritt zum größten Teil sporadisch auf. Jedoch erkranken etwa 3 bis 5% der Pankreaskarzinompatienten mit familiärer Häufung. Es tritt entweder isoliert auf (= familiäres Pankreaskarzinom) oder ist mit so genannten Tumorprädispositionssyndromen assoziiert. Im Gegensatz zu den Tumorprädispositionssyndromen, bei denen Pankreaskarzinome mit den unterschiedlichsten Karzinomen kombiniert auftreten, konnte für das familiäre Pankreaskarzinom bislang keine krankheitsauslösende Mutation und damit eine Genlokalisation identifiziert werden. Eines dieser Tumorprädispositionssyndrome ist das Familial atypical multiple mole melanoma-Syndrom (FAMMM-Syndrom). Verschiedene Mutationen im CDKN2A-Gen (Cyclin dependent kinase 2A) auf dem menschlichen Chromosomenabschnitt 9p21 sind für dieses Tumorsyndrom verantwortlich. Ziel dieser Arbeit war daher, eine 1999 entdeckte alternative Splicevariante des CDKN2A-Genlocus, die ausschließlich in humanen Pankreaszellen exprimiert wird, einerseits auf Mutationen zu untersuchen, die ursächlich für ein familiäres Pankreaskarzinom sein könnten, und andererseits weitere Mutationen zu finden, die Ursache für andere Tumorprädispositionssyndrome sein könnten. Es wurde die genomische DNA von 25 Patienten auf konstitutionelle Mutationen untersucht, die im Rahmen der Deutschen Fallsammlung für familiäres Pankreaskarzinom bereits rekrutiert wurden. Die Ergebnisse aus den Sequenzanalysen zeigten bei einem der 25 untersuchten Indexpatienten in der Gruppe des Pankreaskarzinom-Melanom-Syndroms die nonsense Mutation c.148 C&gt;T (Q50X). Die weiteren 24 untersuchten Patienten zeigten keine Mutationen in der alternativen Splicevariante p12 des CDKN2A-Gens. Bei den untersuchten Mitgliedern der hereditären Pankreassyndrom-Familien konnte in der pankreas-spezifischen Splicevariante p12 des CDKN2A-Gens keine Mutation nachgewiesen werden und damit nicht den Verdacht bestätigen, dass Mutationen in einem pankreas-spezifisch exprimierten Gen zur Entstehung von Tumoren beitragen können. Da bisher keine Screening-Untersuchungen an großen Patientengruppen durchgeführt wurden, war ein weiteres Ziel an 42 Probanden, die in keiner Weise einer der Tumordispositions-Syndrom-Gruppen angehören, eine Untersuchung auf Polymorphismen durchzuführen. Es zeigte sich bei keiner Person eine Veränderung der untersuchten Gensequenz. Die genetischen Untersuchungen des hereditären Pankreaskarzinoms werden durch die relativ niedrigen Fallzahlen beschränkt. Durch die Erforschung des Krankheitsverlaufs, der Pathomechanismen inklusive genetischen Veränderungen von Pankreaskarzinompatienten können Hochrisikopatienten in Früherkennungsprogramme aufgenommen und in frühen Tumorstadien bzw. Vorläuferstadien einer chirurgischen Therapie zugeführt werden, die derzeit die einzig potentiell kurative Maßnahme darstellt. Weiterhin wäre durch die Identifizierung von Gendefekten des Pankreaskarzinoms ein Pankreaskarzinomscreeningprogramm denkbar. Forschungsergebnisse von Vorläuferläsionen und genetischen Mechanismen einer hereditären Tumorerkrankung geben sehr oft auch Aufschluss über das sporadische Karzinom. Aus allen diesen Gründen sind auch in Zukunft weitere Untersuchungen von Pankreaskarzinompatienten und deren Angehörigen in kontrollierten Studien- und Fallsammlungen dringend notwendig
