Genomic profiling of Mexican patients with B-cell precursor acute lymphoblastic leukemia reveals clinically significant somatic and potential germline variants. [PDF]

J Pathol Clin Res
Abstract B‐cell precursor acute lymphoblastic leukemia (preB‐ALL) is characterized by pathogenic variants currently used in precision oncology. However, the mutational landscape of Mexican children with preB‐ALL has not yet been thoroughly explored and defined in terms of the clinical significance.

A new, conspicuously pigmented Pyrrhulina (Teleostei: Characiformes: Lebiasinidae) from the Río Tigre, Loreto, Peru. [PDF]

J Fish Biol
Abstract A new species of Pyrrhulina is described based on morphological and molecular evidence. Pyrrhulina punctata is distinguished from all congeners by the presence of a series of 7 to 16 irregular blotches of dark pigmentation on the flanks, equally marked in juveniles and adult specimens, the presence of 26–28 lateral‐line scales, 17–21 maxillary

Cryptic diversity and recent diversification in the Pyrrhulina australis species complex (Characiformes, Lebiasinidae) revealed by mitochondrial DNA. [PDF]

J Fish Biol
Abstract Pyrrhulina australis Eigenmann & Kennedy, 1903, is widely distributed across the main hydrographic basins of South America. The taxonomic integrity of this species is nevertheless challenged by the lack of clear diagnostic characters, its marked geographic variation and the morphological overlap with its congeners. In this context, the present

High‐throughput RNA sequencing of the T cell receptor alpha and beta chains for simultaneous clonality and biological analyses in Sezary syndrome

Journal of Clinical Laboratory Analysis, Volume 37, Issue 23-24, December 2023., 2023
We performed RNA sequencing of TR alpha (TRA) and beta (TRB) in peripheral blood CD4+ T cells from Sezary Syndrome (SS) and psoriasis patients (PS) employed as controls and found correlated (A) and highly expanded predominant TRA and TRB complementarity‐determining regions 3 (CDR3) only in SS patients (B).

SARS‐CoV‐2 infection as cause of in‐utero fetal death: regional multicenter cohort study

Ultrasound in Obstetrics &Gynecology, Volume 62, Issue 6, Page 867-874, December 2023., 2023
ABSTRACT Objective Placental infection with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) can lead to placental insufficiency and in‐utero fetal death (IUFD). The objective of this study was to confirm and quantify the extent to which fetoplacental infection with SARS‐CoV‐2 is a cause of fetal death.

Biogeography and environmental preferences of Butia yatay (Mart.) Becc

Ecology and Evolution, Volume 13, Issue 11, November 2023., 2023
In this study, we focus on the subtropical palm species, Butia yatay, recognized as an endemic flagship taxon within the Chaco Phytogeographical Domain. We determined its current environmental preferences and assess potential shifts in the distribution of B. yatay since the Pleistocene.
