Resumen
Este reporte de caso detalla el primer rabdomiosarcoma (RMS) digital felino, un cáncer raro. El diagnóstico implicó histopatología e inmunohistoquímica, lo que llevó a la amputación de la extremidad y enfatizó la necesidad de una mayor investigación sobre el RMS felino.
Área de la Ciencia:
- Oncología Veterinaria
- Patología Felina
- Oncología Quirúrgica
Sus antecedentes:
- El rabdomiosarcoma (RMS) es un tumor maligno raro en gatos.
- Los tumores digitales en felinos son poco comunes, presentando desafíos diagnósticos y terapéuticos.
- Se observó resección quirúrgica previa para una masa dorsal interescapular en este paciente.
Objetivo del estudio:
- Reportar el primer caso de rabdomiosarcoma digital en un paciente felino.
- Describir el proceso diagnóstico, incluyendo histopatología e inmunohistoquímica.
- Resaltar la importancia de comprender el RMS felino para mejorar el manejo y el pronóstico.
Principales métodos:
- Biopsia incisional quirúrgica de una masa falángica en la extremidad anterior derecha.
- Análisis histopatológico e inmunohistoquímico del tejido tumoral.
- Amputación de la extremidad anterior derecha como intervención terapéutica.
Principales resultados:
- La inmunohistoquímica confirmó que las células tumorales eran positivas para desmina, vimentina y proteína de determinación de mioblastos 1.
- Las características histológicas fueron consistentes con un subtipo embrionario de rabdomiosarcoma.
- Se estableció el diagnóstico de rabdomiosarcoma digital en un gato.
Conclusiones:
- Este es el primer caso reportado de rabdomiosarcoma digital en un gato.
- Son esenciales estudios adicionales sobre la presentación clínica, el tratamiento y el pronóstico del RMS felino.
- Este caso proporciona información valiosa para el manejo de casos similares de rabdomiosarcoma felino.

Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

01:47Primary Active Transport
197.9K
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

01:20Embryonic Connective Tissues
6.4K
During early development, the embryo forms two types of connective tissues— the mesenchyme and mucoid connective tissue.
The mesenchyme is the first connective tissue that emerges in the developing embryo. It consists of loosely arranged multipotent mesenchymal cells and reticular fibers in the extracellular matrix. This loose arrangement allows easy migration of cells, which is essential for germ layer positioning, patterning, and organ morphogenesis during embryonic development.

176
Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...
