Experimental investigations about the stability of the spongiosa of the femoral head, a new angle plate in mind

1990

Im Hinblick auf den Trochanter-major-Abbruch bei und nach Winkelplattenosteosynthesen von pertrochanteren Frakturen wurde zu Versuchszwecken eine 130o-Winkelplatte mit lediglich 6 mm breitem Klingenprofil angefertigt, bei der das notwendige Knochenfenster die laterale Femurkortikalis weniger schwacht. Die Fragestellung war, ob diese Plattenklinge hinsichtlich der Tragfahigkeit des Osteosynthesesystems vergleichbar stabil in der Spongiosa des Huftkopfes verankert werden kann wie die herkommliche 130o-Winkelplatte. Dazu wurden an Knochenpraparaten vergleichende Druckbelastbarkeitsversuche, von pertrochanteren Osteotomien durchgefuhrt. Die Ergebnisse zeigen, das die neuartige Klinge mit dem sc…

Entwicklung eines Wachstumsmodells für fetale Kopf- und Rumpfmaße

1987

Head parameters BPD, FOD and HC and abdomen parameters ATD, APD and AC have been ascertained in a prospective cross-sectional study in 515 healthy single fetuses between 13 and 40 weeks of gestation by ultrasound. In all cases ultrasound velocity was 1540 m/sec. From these data, a growth model was achieved for each parameter and corresponding growth curves with 5%, 10%, 50%, 90% and 95% percentiles were established.

Challenges and Solutions for Tracing Storage Systems

2018

IBM Spectrum Scale’s parallel file system General Parallel File System (GPFS) has a 20-year development history with over 100 contributing developers. Its ability to support strict POSIX semantics across more than 10K clients leads to a complex design with intricate interactions between the cluster nodes. Tracing has proven to be a vital tool to understand the behavior and the anomalies of such a complex software product. However, the necessary trace information is often buried in hundreds of gigabytes of by-product trace records. Further, the overhead of tracing can significantly impact running applications and file system performance, limiting the use of tracing in a production system. In…

Strategies for Heading Off is Project Failure

2000

Although investment in information technology and information systems continues to increase, projects continue to fail. As a result, IS projects, particularly software projects, are perceived as high risk. By categorizing types of risk, this article helps IS professionals and all project sponsors to identify classes of risk and choose the appropriate managerial behavior to mitigate each of them.

Effects of dietary administration of fenugreek seeds, alone or in combination with probiotics, on growth performance parameters, humoral immune respo…

2016

The use of immunostimulants is considered a promising preventive practice that may help to maintain animal welfare and a healthy environment, while increasing production and providing higher profits. The purpose of this study was to evaluate the effects on gilthead seabream (Sparus aurata L.) of the dietary administration of fenugreek (Trigonella foenum graecum) seeds, alone or combined with one of the following probiotic strains: Bacillus licheniformis (TSB27), Lactobacillus plantarum or Bacillus subtilis (B46). Gilthead seabream were fed a control or one of the supplemented diets for 3 weeks. The effects of these supplemented diets on growth performance parameters and the humoral immune r…

In vitro cytokine profile revealed differences from dorsal and ventral skin susceptibility to pathogen-probiotic interaction in gilthead seabream

2016

Skin is the first barrier of defense on fish, which is crucial to protection against different stressors, including pathogens. Skin samples obtained from dorsal and ventral part of Sparus aurata specimens were incubated with Photobacterium damselae subsp. piscicida (a pathogen for this fish species), with Shewanella putrefaciens Pdp11 (a probiotic bacteria isolated from healthy gilthead seabream skin) or with both bacteria. The gene expression profile of nine cytokines (il1b, tnfa, il6, il7, il8, il15, il18, il10 and tgfb) was studied by qPCR in all the skin samples. The present findings revealed different patterns of cytokine profile in dorsal and ventral skin of gilthead seabream, which c…

Characterization of PAMP/PRR interactions in European eel (Anguilla anguilla) macrophage-like primary cell cultures

2013

The eel (Anguilla anguilla) has been identified as a vulnerable species with stocks dramatically declining over the past decade. In an effort to support the species from overfishing of wild stocks increased interest in eel aquaculture has been notable. In order to expand the scarce knowledge concerning the biology of this species significant research efforts are required in several fields of biology. The development of cell culture systems to study the immune response is a key step towards an increased understanding of the immune response and to develop resources to support further study in this threatened species. Macrophages are one of the most important effector cells of the innate immun…

cDNA sequence and tissue expression of an antimicrobial peptide, dicentracin; a new component of the moronecidin family isolated from head kidney leu…

2007

A 483-bp cDNA was isolated from sea bass (Dicentrarchus labrax) head kidney leukocytes, dicentracin, using PCR primers designed from conserved moronecidin domains. Gene bank analysis revealed that dicentracin cDNA belongs to the moronecidin family. As deduced from alignment with Morone chrysops moronecidin, the precursor of 79 aa appeared to be composed of a signal peptide of 22 aa, followed by the mature AMP (antimicrobial peptide) of 22 aa named dicentracin, and a C-terminal extension of 35 aa. Dicentracin precursor displayed 3 aa substitutions with other moronecidin sequence but none in the mature peptide sequence. Using in situ hybridization assay, dicentracin gene expression was observ…

Development of Antioxidant Protein Extracts from Gilthead Sea Bream (Sparus aurata) Side Streams Assisted by Pressurized Liquid Extraction (PLE)

2021

The pressurized liquid extraction (PLE) technique was used, for the first time, to obtain protein extracts with antioxidant activity from side streams (muscle, heads, viscera, skin, and tailfins) of gilthead sea bream (Sparus aurata) in order to give added value to these underutilized matrices. Extraction conditions previously optimized for sea bass (Dicentrarchus labrax) side streams were applied. Protein recovery percentages were 22% (muscle), 33% (heads), 78% (viscera), 24% (skin), and 26% (tailfins), which represented an increase of 1.2–4.5-fold compared to control samples (extraction by stirring). The SDS-PAGE profiles revealed that PLE-assisted extraction influenced protein molecular …
