<span>The ischemic penumbra can maintain metabolic demand with marginal blood flow from collateral circulation for a maximum of 50% before increasing in size. A penumbra is the area where the flow of blood at about 25 - 50% can maintain normal metabolic demands for 6 - 8 hours only. When it continues to increase, the human cells will die and other neurological activity will be suspended causing the person to die slowly.</span>

1. Suppose that you take your boat offshore for a day of deep-sea fishing. You drop anchor at a supposed ‘hot spot’ and you noti
Mashcka [7]

The swim bladder is more or less an oval, soft-walled pouch located in the abdominal cavity, just below the spinal column. Its shape varies greatly, but the volume is constant between species, most often around 5% of body.

<h3>Day of deep-sea fishing</h3>

1. The volume of your swim bladder when you put it back in the water would be 7.5 liters.

2. The time the fish would float on the surface before the oval could restore neutral buoyancy would be a few seconds.

3. If I were a red blood cell that has just delivered its oxygen to the tail musculature of a mako shark, the route through the circulatory system to eventually reach the mako's swim bladder would be the venous route, like other fish, they have a heart with two chambers, an atrium and a ventricle, and closed circulation.

With this information, we can conclude that the volume of her swim bladder when she was put back in the water would be 7.5 liters.

It's considered to be an advantage to have lungs with increased capacity, because with increased capacity
matrenka [14]
<span>Having more lung capacity is advantageous because the lungs can expand more. More air in the lungs will fill all the alveoli (air sacs in the lungs) and allow more oxygen to enter the bloodstream via the capillaries that surround the air sacs. Excess waste (such as carbon dioxide) is also transferred from the blood to the air to be exhaled. As lungs fill, more gas exchange can occur.</span>

What are some of the criteria a pharmaceutical company would want to meet if it is producing a drug for sale to consumers
Fynjy0 [20]

Answer:

Fundamento: La industria farmacéutica a nivel internacional tiene entre sus estrategias la propaganda de medicamentos directa al consumidor, para incrementar sus ganancias.

Objetivo: Valorar cómo puede influir la promoción inadecuada en el uso racional de medicamentos y como se presenta en Cuba.

Metodología: Se realizó una búsqueda de información, en fuentes primarias y secundarias, sobre promoción y uso no adecuado de los medicamentos.

Resultados: Se encontró que la propaganda realizada de manera directa al consumidor genera un aumento de las ventas de los productos anunciados, lo cual hace de la promoción una herramienta esencial de marketing para la industria farmacéutica internacional, situación que no es uniforme, sino que varía de un país a otro con un denominador común: las anomalías mayores presentes en los países en desarrollo. La Organización Mundial de la Salud en 1988 publicó los “Criterios éticos para la promoción de medicamentos”, los cuales sirven de base para elaborar regulaciones sanitarias por parte de las autoridades nacionales de salud que permitan garantizar la calidad, seguridad y eficacia de los medicamentos.

Conclusiones. El trabajo conjunto entre autoridades sanitarias, profesionales de la salud y pacientes permitirá lograr un uso adecuado de los medicamentos sin el sesgo que conllevan los mensajes promocionales.

Palabras clave: Industria farmacéutica y ética; ética farmacéutica; control de la publicidad de productos¸ publicidad de medicamentos; tecnología farmacéutica y ética; preparaciones farmacéuticas; medicamentos sin prescripción.

DeCS: INDUSTRIA FARMACÉUTICA/ética; ÉTICA FARMACÉUTICA; CONTROL DE LA PUBLICIDAD DE PRODUCTOS; TECNOLOGÍA FARMACÉUTICA/ética; PREPARACIONES FARMACÉUTICAS.
