Resumen
Este estudio establece datos normativos para el desarrollo mandibular prenatal, proporcionando curvas de crecimiento para mediciones clave desde etapas embrionarias tempranas hasta fetales tardías. Estos datos ayudan en la detección de anomalías craneofaciales y la estimación de la edad en investigaciones forenses.
Área de la Ciencia:
- Desarrollo craneofacial; Diagnóstico prenatal; Morfometría
Sus antecedentes:
- La evaluación precisa del desarrollo mandibular prenatal es crucial para el diagnóstico de anomalías craneofaciales.; Los datos normativos existentes para la morfometría mandibular durante el desarrollo temprano son limitados.
Objetivo del estudio:
- Establecer datos normativos integrales para mediciones morfométricas clave durante el desarrollo mandibular prenatal.; Crear curvas de crecimiento para evaluar las tendencias de desarrollo en la mandíbula humana.
Principales métodos:
- Análisis de 42 especímenes embrionarios y fetales humanos (8-37 semanas de edad gestacional).; Segmentación mandibular utilizando imágenes histológicas, micro-CT o MDCT.; Anotación de 14 puntos de referencia para extraer mediciones como el ancho bigoniaco, la altura del ramo y el ángulo goníaco.
Principales resultados:
- Se observó osificación mandibular a partir de la etapa Carnegie 19 (8+4 semanas de edad gestacional).; Se encontraron fuertes correlaciones significativas entre la edad gestacional y las mediciones mandibulares lineales (R2>0.95).; Correlación inversa significativa moderada entre el ángulo goníaco y la edad gestacional (R2=0.65).
Conclusiones:
- Proporciona datos de referencia normativos integrales para el desarrollo mandibular prenatal.; Las curvas de crecimiento pueden ayudar en el diagnóstico prenatal más temprano y preciso de anomalías craneofaciales.; Los datos normativos pueden ayudar en la estimación de la edad en contextos forenses y arqueológicos.

00:57Population Growth
28.0K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.

01:42Microtubule Associated Proteins (MAPs)
5.8K
Microtubule function and architecture are regulated by an array of specialized proteins called microtubule-associated proteins or MAPs. These proteins are widespread across different organisms and have conserved protein motifs, like the multi-TOG domain for tubulin binding found in the CLASP family of MAPs. Some MAPs are lineage-specific based on their conserved domains. Their functions depend upon the cytoskeletal architecture and cell type they are located within. In-plant cells, a specific...

01:29Exponential Growth
44
Bacterial populations exhibit exponential growth when conditions such as nutrient availability and temperature are favorable. In this phase, cells reproduce through binary fission, where each cell divides into two identical daughter cells. This process causes the population to double at regular intervals, resulting in a growth rate that is directly proportional to the current number of cells. As the population increases, the number of new cells formed during each generation also grows, creating...

01:29Plotting of Topographic Maps
483
Topographic maps represent the Earth's surface features using contour lines, which connect points of equal elevation to create a two-dimensional representation of three-dimensional terrain. Creating a topographic map requires a systematic approach.Begin by plotting a scaled grid and marking intersections corresponding to the survey's elevation data points. Assign elevation values at these intersections to build the base map. Next, determine contour levels using a consistent contour interval,...

01:29Coordinates and Map Projections
586
Coordinates and map projections are essential tools in accurately representing the Earth's surface for various applications, ranging from navigation to spatial analysis. The latitude and longitude coordinate system is a universally recognized framework for defining locations. Latitude specifies the distance of a point north or south of the equator, measured in degrees from 0° at the equator to 90° at the poles. Longitude indicates a location's position east or west of the prime meridian,...
