Phylogenetic relationships of the Mangrove Hummingbird, "Amazilia" boucardi (Apodiformes: Trochilidae) of Costa Rica

Rev. biol. trop; 72 (1), 2024
Abstract Introduction: A recent revision of the generic classification of the Trochilidae based on DNA sequences revealed many inconsistencies with the current generic classification, largely based on plumage characters subject to homoplasy, especially in the Trochilini, the largest tribe. A thorough g...

The possibility of early diagnosis of colorectal cancer through expression of Lncrna UCA1, Lncrna LINC00970, and Wnt genes; an in-vitro study

Acta sci., Health sci; 44 (), 2022
Colorectal cancer is the 4thcause of cancer death; with considering the growth process of this cancer and the necessity of early diagnosis, the purpose of the research is to state the LncRNA 00970, LncRNA UCAI,and the Wntgene before and after the treatment by 5-Azacytidine epigenetic medi...

Avaliação do perfil de metilação dos genes LDLR, PCSK9, LDLRAP1 em pacientes portadores de hipercolesterolemia familial

As variabilidades genotípicas que determinam algumas alterações fenotípicas e metabólicas podem ter seu diagnostico falho se baseado apenas nos dados genômicos. Na hipercolesterolemia familial (HF) pode-se observar que os dados de variantes nos genes da LDLR, PCSK9, APOB e LDLRAP1 sugeridos pelos c...

Assessment of cytotoxicity, genotoxicity, and mutagenicity of the dexchlorpheniramine reference standard and pharmaceutical formula in human peripheral blood mononuclear cells

Abstract Dexchlorpheniramine is a first-generation classical antihistamine, clinically used to treat allergies. The main objective of our study was to evaluate the effects of the dexchlorpheniramine reference standard (DCPA Ref. St) and a pharmaceutical formula on DNA in human peripheral blood mononuclea...

Through DNA sensors and hidden mitochondrial effects of SARS-CoV-2

The COVID-19 pandemic brought attention to studies about viral infections and their impact on the cell machinery. SARS-CoV-2, for example, invades the host cells by ACE2 interaction and possibly hijacks the mitochondria. To better understand the disease and to propose novel treatments, crucial aspects of...
