Are relationships necessary for the development of human social behavior?

Are relationships necessary for the development of human social behavior?

Yes: We learn constantly by the environment and by those around us. Without relationships, we would not learn how our actions affect others. It is critical that infants and children have strong, stable relationships with consistent caregivers to promote normal social interactions. ...Read more

Do doctors believe we humans evolved from a common ancestor of apes and humans? Will we evolve into other forms in future?

Do doctors believe we humans evolved
from a common ancestor of apes and humans? Will we evolve into other forms in future?

Some do, some don't: Doctors are like other people, in that some believe we evolved from a more primitive species, but others believe we were created as modern humans. In either case, we have been evolving and will continue to evolve, ever since the days of the first humans. Doctors who believe we were created as humans, see that we are evolving, but just into slightly different humans, not into another species. ...Read more

Difficult question : Was a biased study with avg age of 63 and lots of smokers and heart disease. No surprise there were more cardiovascular events in the first year! Evened out in second year. Study was stopped too early(pushed by the drug co. That sell drugs for osteoporosis, one of main benefits of hrt) to really know if there is any increased breast cancer risk at all. Everything reads. ...Read more

Why are so many studies done on rats? I don’t understand how they relate to humans.

Why are so many studies done on rats? I don’t understand how they relate to humans.

Closely related: Many times, early clinical trials are done to figure out how a drug or treatment will work, etc. There are well-known "models" of various diseases that are in rats, and so, many experiments which would be harmful if done on humans are usually first done on rats.

Whenever a treatment shows promise, however, there are always human trials, with very strict safety guidelines. ...Read more

How come a lot of places say that in a study, humans had 6 grams of melatonin every day for a month and were fine? Where is this study?

How come a lot of places say that in a study, humans had 6 grams of melatonin every day for a month and were fine? Where is this study?

Milligrams not grams: You mean milligrams, not grams. Patients should use the smallest dose of melatonin necessary for symptomatic relief. Many studies have investigated doses of melatonin at a 6 mg/day or greater dose (one example: http://www.ncbi.nlm.nih.gov/pubmed/107392990. Discuss with your sleep specialist before making any medication dose changes. http://www.nlm.nih.gov/medlineplus/druginfo/natural/940.html ...Read more

How did human immunodeficiency virus (hiv) evolve?

How did human immunodeficiency virus (hiv) evolve?

Evolution: It came from a simian precursor transmitted to humans by one of several mechanisms. This virus mutates continuously and the form to which it mutates which is the best capable of surviving under the circumstances is the one which will be reproduced and multiply within infected cells. Unless of course you are a creationist. ...Read more

Did human beings really evolve from apes? And if so, then does that mean were no more special than an average ape?

Yes and no: The evidence favors the hypothesis that we did, indeed, evolve from apes. But with evolution comes special characteristics. A ferrari "evolved" from an oxcart but it certainly is more special than oxcart. Humans are sentient beings and, arguably, have a soul (depending on your faith). There's no doubt that we communicate and reason far in a far more sophisticated way than apes. ...Read more

Why did the medication "Linzess" kill juvenile mice in the clinical studies? Should this be a concerning result?

Why did the medication "Linzess" kill juvenile mice in the clinical studies? Should this be a concerning result?

Let's think: Mouse studies are animal studies, not clinical studies. It is no surprise that an anti-constipation drug in a huge dose caused fatal diarrhea. Two new Big Pharma meds are competing for the chronic constipation market and it's no wonder there's distortion in what you read. For constipation, check for hypothyroidism, porphyria, and practice good hydration and diet first. Best wishes. ...Read more

What may be the possible result if the human stomach reduces in size ten times?

What may be the possible result if the human stomach reduces in size ten times?

Stomach reduction: The stomach is divided into zones, with each zone responsible for a particular action. For example, a region of the stomach is responsible for acid production, another region is responsible for production of Intrinsic Factor, which is responsible for Vitamin B12 absorption. So reducing the surface area of the stomach may eliminate vital regions of the stomach. ...Read more

Recent studies I found on the internet shows humans loses more calcium trying to consume cow's milk than gaining calcium from it. Is this true?

Recent studies I found on the internet shows humans loses more calcium trying to consume cow's milk than gaining calcium from it. Is this true?

Doesn't make sense: Dairy products are an excellent source of calcium that is easily digested. Plant sources of calcium are not as bioavailable. However, some people have challenges with digesting lactose (sugar contained in milk). This is helped by taking lactase tablets when eating dairy products. Cow milk allergy is rare. ...Read more

I study very hard. But in between I get depressed thinking of the result in the future. I am not able to concentrate well in studies due to stress.

I study very hard. But in between I get depressed thinking of the result in the future. I am not able to concentrate well in studies due to stress.

It sounds like you: Are creating anxiety in yourself by forecasting dismal results in the future. This uses up precious energy ; drops your confidence. I have a suggestion. Try not to project what your grades or the outcome will be. Yes, you are capable of this. Focus your attention ; energy on learning the information. Disconnect the action of studying with the imagined result. Good luck. ...Read more

Had a 2d Echo for pvcs and the test result with LVEF (2d): 42 (>55%) where 55 is norm. But under findings says LVEF is 65 & study EF 65. Why diff?

Had a 2d Echo for pvcs and the test result with LVEF (2d): 42 (>55%) where 55 is norm. But under findings says LVEF is 65 & study EF 65. Why diff?

I'd believe the 65: I agree that it seems confusing because I read it as saying that you've got an LVEF of 42 which for a 31-year-old ain't so hot.....but 65% is a heckuva lot better than 42 so I think that's your real number. Why the difference? Beats the PVC heck outta me.... I think you'll want to check with either the doc who ordered the study or whomever READ the study. Good luck! ...Read more
