Exploring Hox Genes and Their Temporal Expression in an Embryonic Model of Freshwater Crustaceans.

Hox genes have been investigated in various Arthropod species, resulting in the identification of ten Hox genes, organized in a colinear arrangement within the genome. Among arthropods, crustaceans exhibit a remarkable diversity of body shapes, which are associated with a variety of egg types, embryonic development patterns, and importantly, with the modulation of Hox genes to specify the identity of body segments along the antero-posterior axis of the embryo. Although there are more than 52,000 species of crustaceans described, their genomic resources are relatively limited, making it challenging to employ several molecular tools for studying embryonic development.

Modulation of mitochondrial dynamics genes and mtDNA during embryonic development and under UVB exposure.

Studies using the embryos of the freshwater prawn Macrobrachium olfersii have reported changes in embryonic cells after exposure to ultraviolet B (UVB) radiation, such as DNA damage and apoptosis activation. Considering the importance of mitochondria in embryonic cells, this study aimed to characterize the aspects of mitochondrial morphofunctionality in M. olfersii embryos and mitochondrial responses to UVB radiation exposure.

Diagnostic Efficacy of Bone SPECT Techniques in Differentiating Unilateral and Bilateral Condylar Hyperplasia.

This analytical cross-sectional study evaluates diagnostic approaches for active condylar hyperplasia using bone SPECT techniques. : it was compared the effectiveness of relative activity assessments between condyles and quantitative analysis using the condyle/clivus ratio. : This study's findings reveal that the condyle/clivus ratio method significantly outperforms the relative uptake method, achieving a sensitivity of 90.

¿Donde están? Hispanic/Latine inclusion, diversity and representation in the HEALthy Brain and Child Development Study (HBCD).

The HEALthy Brain and Child Development (HBCD) Study, a multi-site prospective longitudinal cohort study, will examine human brain, cognitive, behavioral, social, and emotional development beginning prenatally and planned through early childhood. Central to its mission of reducing health disparities is the establishment of the Spanish Language and Culture Committee (SLCC) within the HBCD framework, a significant step towards demographic representation and inclusivity in research. By addressing linguistic and sociocultural barriers and embracing the diverse identities of Hispanic/Latine individuals nationwide, the SLCC aims to promote inclusion, equity, and representation of all Hispanic/Latine subgroups, a population that has been historically misrepresented in health research.

infection induces the expression of the chemokine CXCL16 in macrophages to promote chemoattraction of CXCR6 cells.

CXCL16 is a multifaceted chemokine expressed by macrophages and other immune cells in response to viral and bacterial pathogens. However, few studies have investigated its role in parasitic infections. The obligate intracellular parasite () is the causative agent of toxoplasmosis, an infection with potentially deleterious consequences in immunocompromised individuals and the developing fetus of acutely infected pregnant women.
