Immunohistochemical Localization of Glucose Transporter GLUT1 and GLUT3 in the Testes of some Mammals

Int. j. morphol; 42 (3), 2024
SUMMARY: Glucose has an essential role in the proliferation and survival of testicular tissue. Glucose transporters (GLUTs) are responsible for glucose uptake across cell membranes. In the present work, two main isoforms GLUT1 and GLUT3 were investigated in the testes of Laboratory mouse (BALB/c), Lesser...

Escenarios lácteos y microbiota intestinal en los primeros 1000 días

Arch. argent. pediatr; 121 (6), 2023
La leche humana es el estándar de oro para la nutrición del bebé y debe iniciarse en la primera hora de vida. La leche de vaca, de otros mamíferos o las bebidas vegetales no se deben ofrecer antes del año de vida. Sin embargo, algunos niños requieren, al menos en parte, de fórmulas infantiles. Aun...

Medium and large-sized mammals of a private protected wetland in the Cerrado-Amazon biological corridor, Brazil

Braz. j. biol; 83 (), 2023
Abstract Brazil is the world's richest country in biodiversity, including mammal species. In the Brazilian Cerrado biome, mammalian diversity is vast, with about 251 species, 32 of them are endemic and 22 listed as threatened species. In this work, we investigated species diversity of medium- and large-s...

Conformational characterization of the mammalian-expressed SARS-CoV-2 recombinant receptor binding domain, a COVID-19 vaccine

Biol. Res; 56 (), 2023
The COVID-19 pandemic has caused a large number of diseases worldwide. There are few vaccines to constrain this disease and the value of them is high. In this sense, the antigens of the vaccine platform Soberana, the receptor binding domain from SARS-CoV-2 Spike protein, both the monomeric (mRBD) and dim...

Zebrafish ambra1b knockout reveals a novel role for Ambra1 in primordial germ cells survival, sex differentiation and reproduction

Biol. Res; 56 (), 2023
BACKGROUND: AMBRA1 is an intrinsically disordered protein, working as a scaffold molecule to coordinate, by protein-protein interaction, many cellular processes, including autophagy, mitophagy, apoptosis and cell cycle progression. The zebrafish genome contains two ambra1 paralogous genes (a and b), both...

Áreas en riesgo para los mamíferos marinos en Colombia

Rev. biol. trop; 70 (1), 2022
Resumen Introducción: Los mamíferos marinos se ven afectados por diversas amenazas que deben identificarse para los esfuerzos de mitigación. Objetivo: Cuantificar visualmente las amenazas a los mamíferos marinos en Colombia e identificar acciones de mitigación. Métodos: Georreferenciamos las amenaz...

Sperm DNA damage compromises embryo development, but not oocyte fertilisation in pigs

Biol. Res; 55 (), 2022
BACKGROUND: The assessment of sperm DNA integrity has been proposed as a complementary test to conventional mammalian semen analysis. In this sense, single-strand (SSB) and double-strand (DSB) DNA breaks, the two types of sperm DNA fragmentation (SDF), have been reported to have different aetiologies and...

The production of the first functional antibody mimetic in higher plants: the chloroplast makes the DARPin G3 for HER2 imaging in oncology

Biol. Res; 55 (), 2022
BACKGROUND: Designed mimetic molecules are attractive tools in biopharmaceuticals and synthetic biology. They require mass and functional production for the assessment of upcoming challenges in the near future. The DARPin family is considered a mimetic pharmaceutical peptide group with high affinity bind...

Anisakidosis diagnosticada tras la expulsión de vermes en deposiciones: forma poco frecuente de diagnóstico en humanos

Rev. chil. infectol; 38 (5), 2021
Resumen La anisakidosis es una zoonosis parasitaria accidental y cosmopolita de los seres humanos, siendo su hospedero definitivo los mamíferos marinos como lobos de mar, focas y delfines, entre otros. El ser humano se infecta por el consumo en estado larvario del nemátodo de la familia Anisakidae pres...

Completitud de inventarios rápidos de diversidad de mamíferos medianos y grandes en la Amazonía noroccidental colombiana
Completeness of rapid assessments of medium and large mammal diversity in the northwestern Amazon in Colombia

Acta amaz; 51 (3), 2021
Las evaluaciones rápidas de biodiversidad son la fuente de información más común sobre biodiversidad en el noroccidente amazónico en Colombia debido a que los recursos y la logística son limitados. Estas evaluaciones son esenciales para tomar decisiones ambientales en esta área que ha sido impac...
