Resumen

El bajo peso al nacer aumenta el riesgo de hipertensión en la edad adulta, independientemente de la genética y el entorno compartido. Este gran estudio de gemelos confirma los orígenes fetales de la hipertensión, incluso después de tener en cuenta los factores de riesgo adultos como el IMC.

Área de la Ciencia:

Epidemiología La epidemiología.
Investigación cardiovascular Investigación cardiovascular Investigación cardiovascular Investigación cardiovascular Investigación cardiovascular
La medicina perinatal es una medicina que se desarrolla en el perinatal.

Sus antecedentes:

El bajo peso al nacer está relacionado con la enfermedad cardiovascular en adultos.
Los factores genéticos y socioeconómicos pueden confundir esta asociación.

Objetivo del estudio:

Para investigar la asociación entre el peso al nacer y el riesgo de hipertensión.
Para controlar los factores genéticos y ambientales compartidos utilizando estudios gemelos.

Principales métodos:

Análisis de cohorte de 16.265 gemelos suecos.
Análisis de control de gemelos anidados en gemelos dizigóticos y monozigóticos discordantes para la hipertensión.
Datos recopilados de registros de nacimiento y cuestionarios/entrevistas de adultos.

Principales resultados:

Una disminución de 500 g en el peso al nacer se asoció con un aumento del 42% en el riesgo de hipertensión en el análisis de cohorte.
Los análisis de gemelos mostraron un mayor riesgo de hipertensión con un menor peso al nacer (OR 1,34 para dizigóticos, 1,74 para monozigóticos).

Conclusiones:

La disminución del peso al nacer se asocia de forma independiente con un mayor riesgo de hipertensión.
Los hallazgos sugieren orígenes fetales de la hipertensión, independientemente de los factores genéticos y ambientales compartidos.
La asociación persiste después de controlar los factores de riesgo para adultos como el IMC.

Degree of Curvature and Radius of Curvature

Degree of Curvature and Radius of Curvature

The degree of curvature and the radius of curvature are fundamental concepts in determining the sharpness or smoothness of a curve. The degree of curvature is a measure of how steeply a curve bends and can be determined using the chord basis or the arc basis. In the chord basis method, the degree of curvature is defined as the central angle subtended by a chord of 30.48 meters, helping in the calculation of the radius of the curve. The arc basis method defines the degree of...

Fusion of Secretory Vesicles with the Plasma Membrane

Fusion of Secretory Vesicles with the Plasma Membrane

Proteins and neurotransmitters in secretory vesicles can be released from a cell upon vesicle docking, priming, and fusion with the plasma membrane. Vesicles are docked and primed in preparation for the quick exocytosis of their contents in response to a stimulus. The fusion process is mainly carried out by a SNAP Receptor or SNARE complex, consisting of synaptobrevin, syntaxin-1, and SNAP-25.
In 1993, Jim Rothman proposed that the antiparallel pairing of vesicular and transmembrane SNAREs, or...

Synaptic Signaling

Synaptic Signaling

Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.

Synaptic Signaling

Synaptic Signaling

Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.
The presynaptic neuron fires an action potential that...

SNAREs and Membrane Fusion

SNAREs and Membrane Fusion

Once a transport vesicle has recognized its target organelle, the vesicular membrane needs to fuse with the target membrane to unload the cargo. Transmembrane proteins called SNAREs present on organelle membranes and their vesicles, mediate vesicle fusion.
SNAREs exist in pairs that symmetrically interact and catalyze the fusion of the lipid bilayers in vesicle and target organelle. v-SNARE in the vesicle membrane are single polypeptide chains that bind to a complementary t-SNARE, composed of 2...

Nuclear Fusion

Nuclear Fusion

The process of converting very light nuclei into heavier nuclei is also accompanied by the conversion of mass into large amounts of energy, a process called fusion. The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and ultimately produce one helium nucleus and two positrons.
A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about...
