Hello everyone. I was wondering if someone could help me get some names of a few pharmaceutical vademecums softwares. You know, the kind you can find on-line or use in your pc, or install in your poket PC or Palm. I've been told these are quite good to have around once you start your rotations as a medical student. Thanks! :lol:

you guys are loosing the context of this article. Stop talking about what if we could make a perfect copy... the mind... memory and fearless armies. The UN has to give some sort of opinion against or with cloning. the problem most advanced countries pose is that the UN gave an ambigous point of view against cloning. I think cloning a human being is completely uselss, by the other hand cloning organs, gene therapy and all other forms of clinical use with the human genome should be permitted.

the link isnt working. i would love to read that article, it might help me understand about parasites and ther role in ecology.

Hello everyone, i do not post much in hypography forums but i read a lot of news and stuff, but thats not the point, just saying hi, here goes my thread. Last time i was reading something about symbiosis(in english) and then i read something about simbiosis(in spanish). And there seems to be a small difference. I need you guys to define the anglosaxon word of symbiosis for me. What i have understood is that symbiosis means any interaction between 2 species, doesnt matter if its beneficial for both or not. But in simbiosis(spanish word) it means a beneficial interaction between 2 species with physical interaction. Can you guys help me out with that please? Im from Peru, our main language is spanish so i have to use the simbiosis defenition but i talk english a lot so i need to have clear the symbiosis definition too. And the other thing is, are parasites biological regulators? do they help with the cycle of life? do they have a role in energy flow of the ecological systems? do they have a role in the food chain? or are they just there to take advantage of a host and produce pathologies.

is the link still working? when i open it its a blank page :confused: i wanted to read about it too... *sniff*

To complement some of the information posted by CraigD, there are 2 types of hypertension. You can have hypertension detected in the sistolic pressure(maximum) or hypertension detected in the diastolic pressure (minimum). As CraigD said, there are 2 values, e.g 120/80 which is a healthy value. The sistolic is when the heart pumps the blood, and the diastolic is the returning pressure. The sistolic pressure is the one that rises the most, it rises with: when digesting, doing exercise, age, high cholesterol, too much salt in blood, diabetes, even emotional changes can make the sistolic pressure rise, my grandmother has 180 of sistolic and she feels fine, when she is angry she rises to 220! and when she wakes up in the mornings she is down to 160, incredible! The problem comes when the diastolic pressure is high. It will have long-term effects, and probably need help, its caused by diseases and other serious factors. Thanks God my grandma's diastolic pressure stays around 60 (old people diastolic pressure tends to be lower). But dont be fooled by mild hipertension problems like my grandma's, even though you feel fine, hypertension, here in Peru is called invisible public enemy number 1. You can feel just fine for years, and then it strikes. Having high pressure also indicates that you might not live much, and it cannot be cured, i know my grandma wont last longer than other old people with less hypertension issues. One last note: if having hypertension in the diastolic means trouble, having hypotension in the sistolic means quick death.

Hmm.. well, im new to these forums (hey there). also, i dont have evidence for this, but i once saw that there is a certain species of lizard that does not have males. The females can reproduce themselves, they have the ova, and they fertilize it themselves. (though they still make some mating ritual before reproducing, which indicates males existed.) So the hypothesis is the following: many years ago, the Y chromosome was a lot bigger, and it has been observed that it is still getting smaller. What if this Y chromosome was to dissapear? maybe males in the future will be an extinct race, and females would be able to reproduce alone. Sorry for my english, im not native speaker, greetings from Peru to all, these forums are great :Waldo:

whoa! i really think these advance is a major breakthrough. Imagine how many respiratory diseases cn be treated this way. Tuberculosis, fibrosis, cancer and all kinds of damaged and atrophic lungs (which many come from genetic diseases).

Well, actually it is said that the heart will pump blood faster, (you'll feel your pulse rate increasing for a while) because of the lack of O2 in your arteries. Just put it this way: when you are doing exercise, you need more oxigen dilvered and faster to all your cells. When you hold your breath your cells will ask for more O2 and the heart will try to remedy this by pumping faster. Impress your teacher by saying these are some of the side effects of hypoxia (low O2).
