TREC and KREC as prognostic markers of HIV infection and COVID-19

Tuberculosis and Lung Diseases, 2022
In some infectious diseases, the number of T- and B-lymphocytes is significantly reduced which is associated with a high risk of the disease progression. The article reviews the effect of two RNA-containing viruses on the specific immune system: SARS-CoV-2 and HIV, as well as parameters of T- and B-cell neogenesis of TREC and KREC, which are markers of

Probing background ionization: Positive streamers with varying pulse repetition rate and with a radioactive admixture [PDF]

, 2011
Positive streamers need a source of free electrons ahead of them to propagate. A streamer can supply these electrons by itself through photo-ionization, or the electrons can be present due to external background ionization.

Multiscale Modeling and Simulation of Organic Solar Cells [PDF]

, 2012
In this article, we continue our mathematical study of organic solar cells (OSCs) and propose a two-scale (micro- and macro-scale) model of heterojunction OSCs with interface geometries characterized by an arbitrarily complex morphology.

TRIAGEM NEONATAL DE IMUNODEFICIÊNCIAS GRAVES COMBINADAS POR MEIO DE TRECS E KRECS: SEGUNDO ESTUDO PILOTO NO BRASIL [PDF]

Revista paulista de pediatria : orgao oficial da Sociedade de Pediatria de Sao Paulo, 2017
To validate the quantification of T-cell receptor excision circles (TRECs) and kappa-deleting recombination excision circles (KRECs) by real-time polymerase chain reaction (qRT-PCR) for newborn screening of primary immunodeficiencies with defects in T and/or B cells in Brazil.Blood samples from newborns and controls were collected on filter paper.

Lymphocyte Subgroups and KREC Numbers in Common Variable Immunodeficiency: A Single Center Study

Journal of Clinical Immunology, 2020
Common variable immunodeficiency (CVID) results in defective B cell differentiation and impaired antibody production and is the most common symptomatic primary immunodeficiency. Our aim was to evaluate the correlation among B cell subgroups, κ-deleting recombination excision circle (KREC) copy numbers, and clinical and immunological data of the ...

Heavy quark radiation in NLO+PS POWHEG generators [PDF]

, 2017
In this paper we deal with radiation from heavy quarks in the context of next-to-leading order calculations matched to parton shower generators. A new algorithm for radiation from massive quarks is presented that has considerable advantages over the one ...
