Establishing Simultaneous T Cell Receptor Excision Circles (TREC) and K-Deleting Recombination Excision Circles (KREC) Quantification Assays and Laboratory Reference Intervals in Healthy Individuals of Different Age Groups in Hong Kong

Frontiers in Immunology, 2020
The clinical experience gathered throughout the years has raised awareness of primary immunodeficiency diseases (PIDD). T cell receptor excision circles (TREC) and kappa-deleting recombination excision circles (KREC) assays for thymic and bone marrow ...

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

Normal neonatal TREC and KREC levels in early onset juvenile idiopathic arthritis

Clinical Immunology, 2023
Dysregulated central tolerance predisposes to autoimmune diseases. Reduced thymic output as well as compromised central B cell tolerance checkpoints have been proposed in the pathogenesis of juvenile idiopathic arthritis (JIA). The aim of this study was to investigate neonatal levels of T-cell receptor excision circles (TRECs) and kappa-deleting ...

Features of the pre-analytical stage in quantitative determination of TREC/KREC in peripheral blood

Медицинская иммунология, 2023
The use of dried blood spots (DBS) obtained from the heels of infants has many advantages over the collection of whole blood samples. DNA extracted from DBS can be used to detect genetic diseases by PCR, which has contributed to the development of ...

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 ...

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.

Assessment of trec and krec levels in COVID-19 patients with varying disease severity

Инфекция и иммунитет, 2023
According to the WHO data, the number of infected people exceeded 765.2 million people during the COVID-19 pandemic. The severity of patient’s condition is determined by immune system hyperactivation.
