Venous thromboembolism in patients with hairy cell leukemia.

Background: Hairy cell leukemia (HCL) is rare leukemia of mature B cells, accounting for 2% of all lymphoid neoplasms. Although the association of venous thromboembolism (VTE) with cancer is well established, there is no systematic study describing VTE in HCL.

Aim: To analyze prevalence and risk factors associated with VTE in HCL patients.

Genetic barcodes for species identification and phylogenetic estimation in ghost spiders (Araneae: Anyphaenidae: Amaurobioidinae).

The identification of spider species presents many challenges, since in most cases the characters used are from genital structures that are only fully developed in the adult stage, hence the identification of immatures is most often not possible. Additionally, these structures usually also present some intra-specific variability, which in some cases makes the identification of closely related species difficult. The genetic barcode technique (DNA barcodes), based on sequencing of the mitochondrial marker cytochrome c oxidase subunit I (COI ), has proven a useful, complementary tool to overcome these limitations.

Novel Bragg peak characterization method using proton flux measurements on plastic scintillators.

. Bragg peak measurements play a key role in the beam quality assurance in proton therapy. Used as base data for the treatment planning softwares, the accuracy of the data is crucial when defining the range of the protons in the patient.
