Soft tissue and visceral sarcomas: ESMO-EURACAN-GENTURIS Clinical Practice Guidelines for diagnosis, treatment and follow-up

Soft tissue sarcomas (STSs) comprise ∼80 entities defined by the World Health Organization (WHO) classification based on a combination of distinctive morphological, immunohistochemical and molecular features.1 These ESMO–EURACAN–GENTURIS (European Society for Medical Oncology; European Reference Network for Rare Adult Solid Cancers; European Reference Network for Genetic Tumour Risk Syndromes) Clinical Practice Guidelines (CPGs) will cover STSs, with the exception of gastrointestinal stromal tumours (GISTs) that are covered in the ESMO–EURACAN–GENTURIS GIST CPGs.2 EURACAN and GENTURIS are the European Reference Networks connecting European institutions, appointed by their governments, to cover rare adult solid cancers and genetic cancer risk syndromes, respectively. Extraskeletal Ewing sarcoma, round cell sarcoma with EWSR1-non-ETS fusion and sarcomas with CIC rearrangements and BCOR genetic alterations are covered by the ESMO–EURACAN–GENTURIS–ERN PaedCan (European Reference Network for Paediatric Oncology) bone sarcomas CPG.3 Kaposi's sarcoma, embryonal and alveolar rhabdomyosarcoma are not discussed in this manuscript, while pleomorphic rhabdomyosarcoma is viewed as a high-grade, adult-type STS. Finally, extraskeletal osteosarcoma is also a considered a high-grade STS, whose clinical resemblance with osteosarcoma of bone is doubtful. The methodology followed during the consensus meeting is specified at the end of the manuscript in a dedicated paragraph

Autoradiographic distribution of galanin binding sites in the brain and pituitary of the sea bass (Dicentrarchus labrax).

Specific binding sites for galanin (GAL) were detected in brain and pituitary of a marine teleost fish, the sea bass, after in vitro incubation of tissue sections with [125I]GAL and light microscopic autoradiography. Binding conditions were optimized and as a result the binding was saturable and specific. In the brain, [125I]GAL binding was found to occur in all parts of the dorsal and ventral telencephalon, in the anterior, tuberal and posterior hypothalamus, in the thalamus and in the tectum opticum, in the inferior lobe and in the ventral medulla oblongata. In the pituitary dense [125I]GAL binding was confined to the area occupied by the prolactin cells in the rostral part of the adenohypophysis. These findings provide the first anatomical evidence for the presence of GAL specific binding sites in the teleost brain and pituitary

Characterisation of chicken monocytes, macrophages and interdigitating cells by the monoclonal antibody KUL01

&lt;p&gt;The distribution, function and ontogeny of the mononuclear phagocyte system of the chicken were characterised using the monoclonal antibody (MAb) KUL01. KUL01 specifically recognises chicken monocytes, macrophages and interdigitating cells, as well as activated microglia cells. Its tissue distribution allowed to discriminate KUL01 from all earlier described MAb, reactive with mononuclear phagocytes. The specificity of KUL01 for mononuclear phagocytes was further confirmed in functional assays: KUL01-positive macrophages in spleen and liver actively took up colloidal carbon, while monocytes and spleen and gut macrophages contained non-specific esterase and acid phosphatase activities characteristic for antigen-processing. Further, it was demonstrated that KUL01-reactive peripheral blood monocytes express MHC-II, but not CD4. In all tissues investigated, the same morphological subtypes of macrophages were detected in chicken at similar localisations as in mammals, indicating a high degree of conservation between the mononuclear phagocyte system of the chicken and of mammals.&lt;/p&gt;</p
