1. Exocrine glands are glands that retain ducts to body surfaces. Most glands of the body are exocrine types with ducts connecting to anatomical surfaces; salivary, sweat. Endocrine glands are therefore referred to as "ductless" glands. Endocrine glands are the hormone producing structures of the body; pancreas, thyroid. Ugh, only one answer per question ><

It's considered poor form to post a laundry list of your homework questions on Y!A. I suggest you Google each term or look it up in your glossary. You'll be a better person for it. Good luck in your studies, ~ Mitch ~
2 :
I provided as many of the search areas as Yahoo Answers permits (10) at the other area where you placed your question: http://answers.yahoo.com/question/index;_ylt=AiF.VHHg301RYLVdIslr1twjzKIX;_ylv=3?qid=20090806211605AALgfYl I do want to mention that if you are taking this course because it is a requirement for a field other than Health, it is still important to learn how to research for a quick answer. The whole idea of taking a course is to learn something...not just to get unearned credit. Here are some of the best and easiest sites to use: http://health.nih.gov/ Just type in the keyword - disease in the box and you will be given a selection. Try the first and second ones. Another easy site is the Mayo Clinic using the same procedure as above:: http://www.mayoclinic.com/ That said here are the best keywords and other info to use for each question: 26) I provided website information in my previous answer - this is one where you should really read - I'd avoid Wikipedia on this one as it will just confuse you. 27) The answers are in the other answer I provided Type in "Diabetes Type 4" to begin with - you'll find a shorter selection which will lead you to a discussion of all types and therefore your answer. 28) Warning signs of skin cancer or just think logically and then double check. 29) Fatal form of skin cancer "Most dangerous form of skin cancer" or just enter each term provided in the multiple choice 30) Begin at the top of your list and stop when you think you have the answer - If you're not sure, continue to the last 2. 31) Begin at the top of your list and check each term. 32) The search is "atherosclerosis" - very basic 33) Cancer - survival You could also type in "American Cancer Society" http://www.cancer.org/docroot/home/index.asp 34) Begin with Alzheimer's disease move on to Parkinson's disease Paget's Disease Graves disease 35) "Hypertension" and then each of the choices You can do this and you need to do it. Would you want a doctor or nurse who made it through med school by getting the answers at Yahoo Answers?

Can someone be allowed to not keep Roza

Can someone be allowed to not keep Roza?
Asasalam Alaikum everyone! Well, my father has diabetes type 2 and everyone's been telling him that he's excused from observing Roza. And being a Biology student I know that a person suffering from Diabetes Mellitus should not go without food intake for long since their catabolism is quite high. So that means their body burns out food faster. And I know that people travelling or very ill ARE relieved from keeping Roza. So can my father..umm...not keep Roza? Is he excused or not? Thanks!!:) P.S. But he IS keeping them anyway. He might miss a couple of days later if he feels unable to cope. But he always observes all Rozas.

well since i am not that much into biology i just know a few things about it i dont know what i am saying is right or not. but if it is dibaties then why dosent he take the meds in sehri and then in iftari and then before sleeping? that would be a good idea no? though since i am not a medical student i dont know much. but he should try to keep fasts. but if it is fatal to him then he should not observe fasts. and if it is very dangerous for him to take fasts then it might even be not liked according to islam for him to keep fasts. but if he is healthy and can take fasts then he should.

Yes. Allowed. Nothing to force when someone is ill. Allah is kind.

So I read an article type in yahoo "answer"from a user to an asker about Ramadan he/she mentioned according to Islam that if someone is ill and can't fast during Ramadan he/she can skip for only that time but must makeup afterwards when the person is able to... So if he is I'll and can't fast cuz of his illness he can makeup afterwards when he is ready before I think next Ramadan walikum assalam hope I helped:)

Adult diabetes can cause complications, he may need to eat or drink something. He is exempt. The fact that he had intent will get him the rewards either way. He never has to fast. If he takes shots or medicine will also make him exempt. Some people have been know to fast. Perhaps, a medical doctor can convince him not to fast. None is likely to say he should. But who is ill or on a journey shall fast a similar number of days later on. Allah desires your well-being, not your discomfort. (2:183-185)

Same!!! My own father has Diabetes and he has to take medicine to control it, he also keeps it on weekends (When he is not at work) but cannot keep it at work... He is excused as he needs the medicine, I'm sure its okay....x Ramadan Mubara, sister!

Could anyone check my English

Could anyone check my English?
Hi, could someone check the introduction of my thesis, please? I am not an English speaker, and I really want to know whether the grammar and structure of my thesis are matching English-speaker's appetite or not. Thanks! Diabetes mellitus (DM) is a major endocrine disorder which affects approximately 5% of the world’s population. It has a significant impact on the health, quality of life, and life expectancy of patients, as well as on the health care system. Diabetes mellitus is divided into two major categories: type 1 diabetes (formerly known as insulin-dependent diabetes mellitus, or IDDM), and type 2 diabetes (formerly known as non-insulin dependent diabetes mellitus, or NIDDM). In particular, the most common, accounting for 90% of patients is type 2 diabetes. The cause of type 2 diabetes is a combination of resistance to insulin action and an inadequate compensatory insulin-secretory response.    In the past, several studies have been carried out on the potential health effects of soy and soy isoflavones in lowering risk of certain diseases, such as breast cancer and intestinal cancer. Soy intake may improve blood lipid levels in humans and animals and decrease arterial fatty streaks in animals, therefore reducing the risk of developing atherosclerosis. Isoflavones, as the main hypolipidemic agent in soy, was focused on their antioxidative and mild estrogenic activity by considerable research. It also said isoflavone has a role in lowering cholesterol levels. Genistein is one of the main isoflavinoid found in soy beans and is a strong antioxidant.    Agakong, a wild soybean which was bred by means of interspecific cross breeding between Eunhakong (Glycine max) and KLG10084 (Glycine soja), has a green seed-coat color and a very small size. Generally, small seed-sized soybeans have good seed vigor, high hypocotyl elongation, and a high sprout yield. Recent study reported that the total isoflavone contents (9,684.8 μg/g) of Agakong was two or three times more than the proportion of Eunhakong and KLG10084. Agakong3, which was enhanced from Agakong, are expected has a much higher content of total isoflavone comparing to Agakong. In this study, the possible anti-diabetic effects of Agakong3, in db/db mice have been evaluated.

I think you have written your thesis well and put across your ideas quite clearly. There are a few grammatical errors which I have spotted (though I am no expert, but hope it helps improve your thesis). In the second paragraph: " Isoflavones, as the main hypolipidemic agent in soy, were*..." not was because Isoflavones is plural. Also that sentence is not very clear-- were focussed in.. means? "It is* also said that* isoflavone has a role..."-- add a is and that. In third paragraph, remove the coma before and. "A* recent study reported that the total isoflavone content*", not contents. "Agakong3, which was enhanced from Agakong, are to have* a much higher content of isoflavone compared* to Agakong".-- Replace has with "to have" and comparing with "compared". I think the rest is fine. I just gave a cursory glance, so i might have overlooked something, plus I'm not an expert in English, though I think I'm not bad at it. Hope it helps.

2. Why is the serum bicarbonate low? 3. What is the acid-base status of this individual?
A 21 year old noncomplaint male with a history of type I (insulin-dependent) diabetes mellitus was found in a coma. His blood glucose was high, as well as his urine glucose, urine ketones, and serum ketones. His serum bicarbonate was <12 mEq/L. His respiration was exaggerated and his breath had an acetone odor. His blood pressure was 90/60 and his pulse weak and rapid (120).

low bicarb = acidosis
2 :
, he has got a metabolic acidosis, dehidration and coma hiperosmolar
3 :
This is diabetic ketoacidosis. His ketones rose significantly because of a lack of insulin. I think the bicarb is low because the body wastes it (from the kidneys) because in ketoacidosis, the body produces more urine. It's kussmaul respirations, the body is trying to rid carbon dioxide and the ketones produce a fruity smell on the breath. it's a anion gap metabolic acidosis.
