Aims. This work reports new experimental radiative lifetimes and calculated oscillator strengths for transitions from 3d84d levels of astrophysical interest in singly ionized nickel. Methods. Radiative lifetimes of seven high-lying levels of even parity in Ni II (98 400-100 600 cm-1) have been measured using the time-resolved laser-induced fluorescence method. Two-step photon excitation of ions pr

Sepsis is a systemic immune response responsible for considerable morbidity and mortality. Molecular modeling of host-pathogen interactions in the disease state represents a promising strategy to define molecular events of importance for the transition from superficial to invasive infectious diseases. Here we used the Gram-positive bacterium Streptococcus pyogenes as a model system to establish a

A novel multi-jet burner was built to provide one-dimensional laminar flat flames with a wide range of variable parameters for multipurpose quantitative optical measurements. The burner is characterized by two independent plenum chambers, one supporting a matrix of 181 laminar jet flames and the other supporting a co-flow from a perforated plate with small holes evenly distributed among the jets.

Malignant melanoma is a heterogeneous, malignant neoplastic disease, most often originating in the skin. Melanoma is characterized by a high mutational load and has a vastly variable prognosis, depending on disease stage. Genetic aberrations in the mitogen-activating protein kinase (MAPK) pathway are important in melanoma, of which mutations in BRAF and NRAS are the most common. Additionally, recu

Aims: Ticagrelor reduces ischaemic events and mortality in acute coronary syndrome (ACS) vs. clopidogrel. We wished to study clinical outcomes in a large real-world population post-ACS. Methods and results: We performed a prospective cohort study in 45 073 ACS patients enrolled into SwedishWeb system for Enhancement and Development of Evidence-based care in Heart Disease Evaluated According to Rec

Soft tissue tumors are highly heterogeneous with more than 100 subtypes. The chapter describes a large number of fibroblastic/myofibroblastic tumor entities. Alveolar rhabdomyosarcomas (ARMS) and embryonal rhabdomyosarcomas (ERMS) show largely similar patterns of genomic imbalances, although most of them occur at higher frequencies among the latter. The chromosome numbers of 70 undifferentiated pl

Chronic myeloid leukemia (CML) is a clonal bone marrow (BM) disease characterized by neoplastic overproduction of, mainly, granulocytes. The treatment of CML has changed dramatically with the introduction of tyrosine kinase inhibitors (TKIs) targeting the product of the underlying cytogenetic and molecular lesion in CML. The Philadelphia chromosome was the first consistent neoplasia-associated chr

This chapter outlines the methods currently employed in cancer cytogenetics, spanning from chromosome banding to array- and sequencing-based techniques. A correct sampling procedure is the basis for correct scientific and diagnostic conclusions. Chromosome preparation requires live cells, whereas in situ hybridization at least requires intact nuclei, and genome arrays as well as sequencing rely on

Bone tumors constitute a heterogeneous group of neoplasms of skeletal origin. Benign cartilage tumors include osteochondroma, subungual exostosis, bizarre parosteal osteochondromatous proliferation (BPOP), chondromas, synovial chondromatosis, chondroblastoma, and chondromyxoid fibroma. Ewing sarcomas, also known as primitive neuroectodermal tumors (PNET), are highly aggressive small cell round cel

Cytogenetic information is available on roughly 600 neoplasms originating from the thyroid, parathyroid, pituitary, and adrenal glands; from the thymus; and from the endocrine pancreas. Trisomy 7 is found in 30% of adenomas with clonal cytogenetic aberrations. In both the benign and malignant tumors, a combination of gains of or from chromosomes 5, 7, 12, 17, 19, and 20 was observed. Almost all pi

According to Boveri's hypothesis, chromosome abnormalities were the cellular changes causing the transition from normal to malignant proliferation. Technical difficulties prevented reliable visualization of mammalian chromosomes, in both normal and neoplastic cells, throughout the entire first half of the 20th century. Nowell and Hungerford's discovery greatly stimulated interest in cancer cytogen

The first three editions of this acclaimed book presented a much-needed conceptual synthesis of this rapidly moving field. Now, Cancer Cytogenetics, Fourth Edition, offers a comprehensive, expanded, and up-to-date review of recent dramatic advances in this area, incorporating a vast amount of new data from the latest basic and clinical investigations. New contributors reflecting broader internatio

This chapter elaborates on human chromosome nomenclature. It provides a brief summary of the most essential cytogenetic terminology related to the description of chromosome aberrations in neoplastic cells. The chapter outlines criteria for designation of regions and bands for chromosome nomenclature. Regions and bands are numbered consecutively from the centromere outward along each chromosome arm

Acute lymphoblastic leukemia (ALL) is classified as B-lineage ALL (B-ALL) and T-lineage ALL (T-ALL). The incidence of ALL is almost three times higher in white than black children. Among adults, ALL is more frequent in younger patients, with a median age of less than 30 years. The morphology-immunology-cytogenetics (MIC) subgroups are associated with nonrandom karyotypic abnormalities in a manner

This chapter discusses neoplastic karyotypes. It emphasizes the difference between primary and secondary changes and address the questions of why, how, when, and where chromosome abnormalities arise; compare numerical and structural aberrations in terms of how they contribute to tumor development; and also touch upon the issues of what causes cancer-associated chromosome abnormalities and whether

Acute leukemia is a worldwide disease with an incidence of approximately 4/100 000 per year; 70% of the cases are acute myeloid leukemia (AML). The salient pathologic feature of AML is the excessive accumulation of immature myeloid blasts in the bone marrow (BM). This maturation arrest, a characteristic of acute leukemias, prevents normal hematopoiesis and leads, directly or indirectly, to a lack
