which enzyme is not denatured over 60 degree centigrate?

Answers:
taq polymerase - used in the Polymerase Chain Reaction are from thermophylic microbes which were found in geisers and other hot places.

---

There are lots! For the bacteria and other life forms which have adapted to live at high temperatures, *all* of their enzymes have to be stable at those temperatures. Examples of such organisms would be the bacteria which live in the hot springs in Yellowstone and the life forms around the thermal vents in the ocean floor.The above mentioned polymerase from (I believe) T. thermophilus is an excellent example of how scientists have taken advantage of some of the heat stable enzymes found in nature. Just keep in mind that thermophilic organisms have thousands of other heat stable enzymes as well.

---

Taq Polymerase as one of the answerers said..
I just want to add that it's a DNA polymerase isolated from thermus aquaticus which naturally lives in hot springs.

Which discipline or specialty is known to be the worst for spreading nosocomial infections?

Nurses, radiology technicians, respiratory therapists, occupational therpaists, physical therapists, dieticians, or speech pathologists?
Answers:
I would think it would be respiratory therapists. Since pneumonia is one of the more common nosocomial infections, and RTs are working with nearly all of the critically ill patients who are therefore immunosuppressed already, they probably would be more likely to spread nosocomials.

---

Nurses

---

Nosocomial infection is an infection that refers to hospital-acquired. Anyone staying in the ICU for an extended period of time or anyone staying in the hospital for an extended period of time can develop this infection. My answer is The Hospital.

---

None of the above. I think you'll find it's doctors. If it's gotta be one from your list I choose..respirat. therapist.By the way, I'd love to see the original research to support this.

---

I have to go with "none of the above". In most hospital systems the Nurses Aids (LNA's, CNA's) are the ones in the trenches; the ones in constant contact with the patient. They'd have the most opportunity to spread infection.

Which diagnostic technique is used to detect cancer and osteomyelitis?

Answers:
Usually a CAT scan will detect either of those or x-ray depending on what type of cancer. Usually, blood work also is effective in detecting abnormal values pointing to the possibility of cancer.

you need to look on line there are severial collages here in the us. their aere several thousand collage here. just look on line.

---

My alma mater, UAB (U. of Alabama at Birmingham)
Good luck.

---

WVU has an awesome school of pharmacy. http://www.hsc.wvu.edu/sop/

---

Check out the American Associate of Colleges of Pharmacy at www.aacp.com. Since you are a foreign medical graduate, you'll need some specific information about passing certain requirements which is in the link below.

which classof usually treat people who are suffering from phobias?

Answers:
There is an entire grouping of people who can help with these problems. Psychiatrists, who are medical doctors, are the ones who would prescribe medication to help you deal with your phobia. Psychologists, social workers, licensed clinical social workers, pastoral counselors, psychiatric nurses, psychotherapists, hypnotherapists; all of these can also help you. My personal recommendation would be someone who is licensed in hypnotherapy, as well as being licensed in their particular area of mental health .
There are also nurse practitioners and physician's assistants who are beginning to come into the psychiatric field, who can prescribe medications and treat patients with phobias.

---

Psychologist or psychiatrist

---

a clinical psychologist can usually help people with phobias

---

PSYCHOLOGISTS OR PSYCHIATRISTS.take your pick.

---

If one wants to be treated by a medical doctor he or she should contact a psychiatrist, otherwise a clinical psychologist will do.

Which class of people are generally happier: general surgeons or anesthesiologists?

Answers:
People who are drawn to these fields are inherently different, and once they enter training, they are socialized and indoctrinated in very different ways. Since you cannot randomize twins into the two fields in any meaningful number, you'll never know, even if there IS a happier group, whether it was happy people who initially made the choice or whether they got happy once they arrived.I am a general surgeon and overall a pretty happy person. I can certainly say that I have a higher stress job and more reason to occassionally become angry than an anesthesiologist. I can even become angry at anesthesiologists! However, the operating room is an unbelievably fantastic place to work, and many of my anesthesia colleagues and I are more than pleased to be working on the same case together. At the end of the day, when we all go home, my good days make me feel like I've really accomplished something important, and I really ride those experiences high. However, when I have a bad day, I garuntee there is some poor soul who had the worst day of their life, and very possibly their last. I suffer those days pretty hard. I can feel ill, lose sleep, and sometimes it takes me weeks to recover. Anesthesiologists do not ride that roller coaster at all. Most of them wouldn't want to. Many of them wouldn't be able to handle it, if they tried! Whether or not that tells you which ones of us are generally happier, it at least tells you that my profession admits of higher highs and lower lows. I'd say that the people who gravitate to general surgery are the ones for whom this ride is one of the things that tends to make them happy. Anesthesiologists, who have decided in medical school that they want to work in the OR without a high stress lifestyle, have accurately assessed that a more detatched and less stressful relationship to patient care is what would make them happy. Many of them choose this field based on lifestyle.

---

anesthesiologists :-)

---

I think surgeons, bec they get to see all part of the human body one at a time at their own whims and fancies where as anesthe..get to see the whole person either dead or alive.

---

general surgeons by far. if you look at the 'sources of narcissism' (this based sort of on Heinz Kohut's understanding), generally anaesthesiologists, much as psychiatrists and those in the dental care fiel are the ones with the lowest sources (and thus the lowest 'income' for self-esteem), conversely having the highest suicide rates.Simple explanation: when a surgery goes well everyone congratulates the surgeon but how many congratulate the anaesthesiologist? but then when it goes wrong, the anaesthesiologist definetly has something to do.I the case of the psychiatrists, it's simply because of the lack of results derived from this practice.one day you think there's a big improvement with a major depression- next day the person jumped out of a window.anaesthesiologists study way too much to get so little reward. two people you should never say 'wrong' to in school: anaesthesiologists and internists.

---

I've never seen an anesthesiologist raise his voice. Does that help?

---

an anesthesiologist would be happier because they don't have as much pressure on them as a surgeon. surgeons have a lot more responsiblities for obvious reasons. both physicians do have to be on call.
