CRISPR-mediated base editing in mice using cytosine deaminase base editor 4

BACKGROUND: Many human genetic diseases arise from point mutations. These genetic diseases can theoretically be corrected through gene therapy. However, gene therapy in clinical application is still far from mature. Nearly half of the pathogenic single-nucleotide polymorphisms (SNPs) are caused by G:C>A:...

Performance of the quantification of adenosine deaminase and determination of the lactate dehydrogenase/adenosine deaminase ratio for the diagnosis of pleural tuberculosis in children and adolescents

J. bras. pneumol; 47 (2), 2021
ABSTRACT Objective: To evaluate the accuracy of determining the adenosine deaminase (ADA) level, the 2'-deoxyadenosine/ADA ratio, and the LDH/ADA ratio in pleural fluid for the diagnosis of pleural tuberculosis (PT) in children and adolescents. Methods: This was a retrospective cross-sectional study co...

Biochemical characterization of adenosine deaminase (CD26 EC 3. 5. 4. 4) activity in human lymphocyte-rich peripheral blood mononuclear cells

Braz. j. med. biol. res; 54 (8), 2021
The conversion of adenosine to inosine is catalyzed by adenosine deaminase (ADA) (EC 3.5.4.4), which has two isoforms in humans (ADA1 and ADA2) and belongs to the zinc-dependent hydrolase family. ADA modulates lymphocyte function and differentiation, and regulates inflammatory and immune responses. This ...

Role of cancer ratio and other new parameters in the differential diagnosis of malignant pleural effusion

Clinics; 76 (), 2021
OBJECTIVES: We compared the diagnostic potential of cancer ratio (CR, serum lactate dehydrogenase [LDH]/pleural fluid adenosine deaminase [pfADA]), cancer ratio plus (CR plus, cancer ratio/pleural lymphocyte percentage), and age/pfADA ratio with pfADA in malignant pleural effusion. METHODS: Data from 10...

Evolution of potential biomarkers of acute muscle injury after physical exercise

Skeletal muscle injury is a frequent event and diagnosis using the classical blood markers sometimes produces unsatisfactory results. Therefore, objective of the study was to detect new biomarkers in plasma, saliva and urine in response to acute muscle damage induced by physical exercise. A cross-section...

Diagnóstico da tuberculose pleural utilizando ensaios de produção de interferon gama, proteína indutora do interferon 10-kD, adenosina deaminase e modelagem de árvores de classificação
Diagnosis of pleural tuberculosis using interferon gamma release assays, inducible protein of interferon gamma 10-kD, adenosine deaminase and classification tree modeling

A entidade nosológica denominada derrame pleural (DP) apresenta mais de 50 etiologias, sendo a insuficiência cardíaca, as neoplasias, a pneumonia e a tuberculose pleural (TBPl) as causas mais frequentes. As dificuldades para se determinar a causa de um DP é uma realidade seja em locais da estrutura b...

Tuberculosis abdominal: patología infrecuente en un paciente joven: reporte de un caso

Rev. chil. cir; 70 (4), 2018
Resumen Introducción: La tuberculosis abdominal es un problema reemergente, y es una de las enfermedades transmisibles más importante en todo el mundo. A pesar de las expectativas acerca de su erradicación en países en desarrollo, ha sido recientemente declarada de nuevo como una patología de emerg...

Tuberculosis pleural en paciente pediátrico: reporte de un caso y revisión de la literatura

Tuberculosis (TB) is a common cause of pleural effusion in young people from endemic areas. Among the forms of extrapulmonary TB in people with immunodeficiencies, the most frequent localization is the pleura. The use of immunological and molecular biology tests for the diagnosis of TB in pleural fluid a...

Acerca de la tuberculosis extrapulmonar
On extrapulmonary tuberculosis

Repert. med. cir; 26 (2), 2017
La tuberculosis es una enfermedad infecciosa de gran prevalencia en países en vía de desarrollo como el nuestro. Aunque el compromiso pulmonar es el más frecuente y de impacto en la salud pública, existen varias formas extrapulmonares con diversas presentaciones clínicas y de difícil diagnóstico, ...

Effects of purine nucleotide administration on purine nucleotide metabolism in brains of heroin-dependent rats

Braz. j. pharm. sci; 52 (4), 2016
ABSTRACT Heroin is known to enhance catabolism and inhibit anabolism of purine nucleotides, leading to purine nucleotide deficiencies in rat brains. Here, we determined the effect of exogenous purine nucleotide administration on purine nucleotide metabolism in the brains of heroin-dependent rats. Heroin ...
