Immunohistochemical investigation of the brain of aged dogs. I. Detection of neurofibrillary tangles and of 4-hydroxynonenal protein, an oxidative da…
2001
In the aging dog brain lesions develop spontaneously. They share some morphological characteristics with those of Alzheimer 's disease in man. Diffuse and primitive plaques are well known, whereas neuritic plaques rarely develop. Neurofibrillary tangles have not been seen in the canine. The aim of the present investigation was to study major age-related changes of the dog's brain using paraffin sections with respect to cross-immunoreactivity of tau, A beta protein and other immunoreactive components including hydroxynonenal protein, which is a marker for oxidative damage. The occurrence of neurofibrillary tangles and of the protein tau therein was studied in serial brain sections of two dog…
Cellular schwannoma of the retroperitoneum with cystic degeneration, mimicking an ovarian cyst, with CKAE1/AE3 and desmin expression.
2014
Schwannoma is an encapsulated benign tumour usually presenting as a solitary mass on the flexor surfaces of the extremities, neck, mediastinum, posterior spinal roots and cerebellopontine angle, an...

Effect of Morphology and Size of Halloysite Nanotubes on Functional Pectin Bionanocomposites for Food Packaging Applications
2017
Pectin bionanocomposite films filled with various concentrations of two different types of halloysite nanotubes were prepared and characterized in this study as potential films for food packaging applications. The two types of halloysite nanotubes were long and thin (patch) (200-30 000 nm length) and short and stubby (Matauri Bay) (50-3000 nm length) with different morphological, physical, and dispersibility properties. Both matrix (pectin) and reinforcer (halloysite nanotubes) used in this study are considered as biocompatible, natural, and low-cost materials. Various characterization tests including Fourier transform infrared spectroscopy, field emission scanning electron microscopy, rele…
Epigenetics in spine curvature disorders
2022
Abstract Scoliosis is a three-dimensional (3D) structural deformity of the spine with a radiological lateral Cobb angle of ≥ 10°. Several classification systems exist, dividing different types regarding the age of onset or the type of etiology. The minority of cases are secondary to congenital, syndromic of neuromosucular diseases. Most of the cases are classified “idiopathic” due to unknown etiology. These were formally divided by the age of onset into “Infantile Idiopathic Scoliosis” (0–3 years), “Juvenile Idiopathic Scoliosis” (JIS—4–10 years), and “Adolescent Idiopathic Scoliosis” (AIS → 10 years). Since the initiative of the Scoliosis Research Society in 2014 all kind of scoliosis with…
The Prevalence of Glaucoma in Young People.
2017
BACKGROUND Earlier information on the prevalence of glaucoma among children in Germany was based solely on estimates. Reported values for congenital glaucoma range from 1 in 10 000 to 1 in 68 000 depending on ethnic origin. The estimate for juvenile glaucoma is 1 in 44 000. METHODS The Gutenberg Health Study is a populationbased, prospective, monocentric cohort study with 15 010 participants aged 35 to 74. To determine the history-based prevalence of childhood glaucoma, participants were asked about the diagnosis of glaucoma, any operations for glaucoma that were performed, regular use of drugs for glaucoma, and the age of onset of glaucoma. The affected individuals were classified in four …
Self-assembled monolayers on a ferromagnetic permalloy surface.
2015
Self-assembled monolayers (SAMs) are nowadays broadly used as surface protectors or modifiers and play a key role in many technological applications. This has motivated the study of their formation in all kind of materials; however, and despite the current interest in molecular spintronics, the study of SAMs on ferromagnetic surfaces remains almost unexplored. In this paper, we report for the first time a methodology for the formation of SAMs of n-alkylphosphonic acids on permalloy in ambient conditions. The formed monolayers have been fully characterized by means of contact angle measurements, atomic force microscopy, X-ray photoelectron spectroscopy, matrix assisted laser desorption ioniz…
Time-resolved X-ray photoemission electron microscopy: imaging magnetodynamics on the 100 ps scale and below
2005
Abstract We present recent results of time-resolved X-ray photoemission electron microscopy (TR-XPEEM) investigations on magnetic systems. Our studies of microstructured permalloy particles employ a magnetic pump XPEEM probe approach. The stroboscopic experiments feature a time resolution of Δ τ ≤ 130 ps and yield magnetic domain images with a surprising richness of details. We observe a strong influence of incoherent magnetization rotation processes, which lead to complicated transient domain structures with a blocked relaxation behavior.
