Direct radiofluorination of [18F]MH.MZ for 5-HT2A receptor molecular imaging with PET

2012

Imaging the serotonin 2A neuroreceptor with positron emission tomography has been carried out with [11C]MDL 100907 and [18F]altanserin for years. Recently, the MDL 100907 analogue [18F]MH.MZ was developed by combining the increased selectivity profile of MDL 100907 and the favourable radiophysical properties of fluorine-18. Here, we want to report the synthesis of [18F]MH.MZ via direct radiofluorination. Unfortunately, the direct radiofluorination did not have any significant benefits over the indirect labelling method. This is mainly because the precursor for the direct labelling approach is not completely stable and slowly decomposes. However, only one HPLC separation is necessary for the…

A methodical 68Ga-labelling study of DO2A-(butyl- l-tyrosine)2 with cation-exchanger post-processed 68Ga: practical aspects of radiolabelling

2011

Positron emission tomography (PET) with 68Ga is a fast-growing field in molecular imaging, both in research and in clinical routine. The availability of 68Ga via the 68Ge/68Ga radionuclide generator facilitates the development and production of radiopharmaceuticals independent of a cyclotron. The presented work shows a complete 68Ga labelling study exemplified on [68Ga]DO2A-(butyl- l-tyrosine)2, a potential tumour tracer for PET. A methodical sequence is followed to optimize the 68Ga-labelling reaction. Practical aspects are described and the different parameters contributing to the labelling yield are demonstrated. The influence of temperature, time, amount of labelling precursor and pH va…

Spatial and temporal variations in cuticle proteins as revealed by monoclonal antibodies. Immunoblotting analysis and ultrastructural immunolocalizat…

1989

A library of monoclonal antibodies (Mabs) against adult cuticle of Tenebrio was used to visualize the secretion of cuticular antigens during metamorphosis. Immunoblots of water- and urea-soluble proteins, and high resolution immunogold labelling has shown that, except in one clone, the Mabs recognize antigens in the three developmental stages. However, the MW of larval and pupal antigens are different from the adult ones, though sharing common epitopes. Blots of cuticle proteins (CPs) bound to different lectins shown few water-soluble glycosylated proteins weakly or not recognized by the Mabs, suggesting that the majority of the Mabs do not recognize glycosylated epitopes. The immunolocaliz…

Control of murine hair follicle regression (catagen) by TGF‐β1in vivo

2000

The regression phase of the hair cycle (catagen) is an apoptosis-driven process accompanied by terminal differentiation, proteolysis, and matrix remodeling. As an inhibitor of keratinocyte proliferation and inductor of keratinocyte apoptosis, transforming growth factor beta1 (TGF-beta1) has been proposed to play an important role in catagen regulation. This is suggested, for example, by maximal expression of TGF-beta1 and its receptors during late anagen and the onset of catagen of the hair cycle. We examined the potential involvement of TGF-beta1 in catagen control. We compared the first spontaneous entry of hair follicles into catagen between TGF-beta1 null mice and age-matched wild-type …

Abordaje multidisciplinar de un carcinoma sebáceo anaplásico palpebral en una paciente de 40 años

2010

Caso clínico: Mujer de 40 años remitida a nuestro servicio por persistencia durante meses de un cuadro de blefaritis anterior de aspecto indolente con aparición de un nódulo indurado en el párpado superior derecho filiado como chalazion refractario al tratamiento convencional, asociado a adenopatía preauricular ipsilateral. La biopsia extemporánea se informó como carcinoma sebáceo. Procedimos a la exéresis completa de dicho párpado y a su reconstrucción con injerto de mucosa palatina y colgajo glabelar. Posteriormente se practicó un vaciamiento cervical radical por la presencia de adenopatías de aspecto necrótico en diversos territorios linfáticos. Se biopsió el párpado inferior que resultó…

S2k guidelines for the treatment of psoriasis in children and adolescents - Short version part 1.

2019

The present guidelines are aimed at residents and board-certified physicians in the fields of dermatology, pediatrics, pediatric dermatology and pediatric rheumatology as well as policymakers and insurance funds. They were developed by dermatologists and pediatric dermatologists in collaboration with pediatric rheumatologists using a formal consensus process (S2k). The guidelines highlight topics such as disease severity, quality of life, treatment goals as well as problems associated with off-label drug therapy in children. Trigger factors and diagnostic aspects are discussed. The primary focus is on the various topical, systemic and UV-based treatment options available and includes recomm…

Enhanced labelling on alcoholic drinks: reviewing the evidence to guide alcohol policy

2013

Background: Consumer and public health organizations have called for better labelling on alcoholic drinks. However, there is a lack of consensus about the best elements to include. This review summarizes alcohol labelling policy worldwide and examines available evidence to support enhanced labelling. Methods: A literature review was carried out in June-July 2012 on Scopus using the key word 'alcohol' combined with 'allergens', 'labels', 'nutrition information', 'ingredients', 'consumer information' and/or 'warning'. Articles discussing advertising and promotion of alcohol were excluded. A search through Google and the System for Grey Literature in Europe (SIGLE) identified additional source…

Magnifying chromoendoscopy for the detection of premalignant gastrointestinal lesions

2006

The prognosis for patients with malignancies of the gastrointestinal tract is strictly dependent on the early detection of premalignant and malignant lesions. At present, endoscopy can be performed with new, powerful high-resolution or magnifying endoscopes. Comparable to the rapid development in chip technology, the optic features of the newly designed endoscopes offer resolutions that allow new mucosal surface details to be seen. In conjunction with chromoendoscopy, the newly discovered tool of video endoscopy is much easier to use and more impressive than previously used fibreoptic endoscopy. This review summarises the value of magnifying endoscopy in the upper and lower gastrointestinal…
