differentiation

 [dif″er-en″she-a´shun]
1. the distinguishing of one thing from another.
2. the act or process of acquiring completely individual characteristics, such as occurs in the progressive diversification of cells and tissues in the embryo.
3. increase in morphological or chemical heterogeneity.

dif·fer·en·ti·a·tion

(dif'ĕr-en'shē-ā'shŭn),
1. The acquisition or possession of one or more characteristics or functions different from that of the original type. Synonym(s): specialization (2)
2. Synonym(s): differential diagnosis
3. Partial removal of a stain from a histologic section to accentuate the staining differences of tissue components.

n.
1.
a. The act or process of differentiating.

2. Biology The process by which cells or tissues undergo a change toward a more specialized form or function, especially during embryonic development.

differentiation

[dif′əren′shē·ā′shən]
Etymology: L, differentia, difference
1 (in embryology) a process in development in which unspecialized cells or tissues are systemically modified and altered to achieve specific and characteristic physical forms, physiological functions, and chemical properties. Kinds of differentiation are correlative differentiation, functional differentiation, invisible differentiation, and self-differentiation.
2 progressive diversification leading to complexity.
3 acquisition of functions and forms different from those of the original.
4 distinguishing of one thing or disease from another, as in differential diagnosis.
5 (in psychology) mental autonomy or separation of intellect and emotions so that one is not dominated by reactive anxiety of a family or group emotional system.
6 the first subphase of the separation-individuation phase in Mahler's system of preoedipal development. It generally occurs between 5 and 9 months of age, coinciding with the maturation of partial locomotor functioning and the beginning of the child's viewing the mother as a separate being. differentiate, v.

differentiation

Oncology The degree to which tumor cells resemble normal cells; differentiated cells grow more slowly than undifferentiated tumor cells. See Dedifferentiation.

dif·fer·en·ti·a·tion

(dif'ĕr-en-shē-ā'shŭn)
1. The acquisition or possession of one or more characteristics or functions different from that of the original type.
Synonym(s): specialization (2) .
2. Synonym(s): differential diagnosis.
3. Partial removal of a stain from a histologic section to accentuate the staining differences of tissue components.

differentiation

1. The process by which stem cells acquire the special characteristics of the tissues into which they are developing.
2. The degree to which the cells of a tumour resemble, or fail to resemble, those of the tissue from which it arises. A high degree of differentiation implies low malignancy and vice versa .
3. The distinguishing of one disease from another.

differentiation

in mathematics, the use of calculus to compute the change of one variable with respect to another. Equal to the gradient (slope) of a graph of the one plotted against the other.

Patient discussion about differentiation

Q. How do you differentiate between fluorosis and caries? Both appear as white spots on the teeth, so clinically how do you differentiate between them? I know it has something to do with their appearance while wet and dry, but I am not sure what? please help me I can't find this in any book.

A. Only mild fluorosis is seen as white stop lesion on the tooth. It usually comes with brown spots. Look for them. Another method is trying to stick a dental explorer into it (not the Microsoft one- it’ll only be a portal for viruses..) and because caries is demineralized area it will feel kind of sticky. But I wouldn’t do that…it can harm the teeth. Another way is by an x ray. Fluorosis- you will see it as a whiter spot. Caries- a more translucent spot.

Q. Differentiate Wheezing & Asthma My sister who is 29 years old is suffering from wheezing for the past 7 years. Its not a genetic problem. Some times she uses inhaler for temporary recovery. She tried English medicine, homeo and other treatments. Is it an Asthma? I find very difficult in seeing her struggle when she find hard to breathe. Please help to make her free out of this struggle.

A. i see what scares you...it's frustrating to see your loved ones suffer and you cannot help. if she is has an inhaler- that mean she has been to the Dr. and he prescribed her some kind of medicine. without giving a diagnose first...?

Q. how can i differentiate between normal stomach ache and an Appendicitis? I've been having a strange sharp pain in my stomach lately and a friend of mine told me it could be Appendicitis.

A. When you have Appendicitis, there should be a sharp pain on the right lower Abdomen. but you mustn't forget that Appendicitis is an inflammation. which means you'll have a fever some time in the near future, and it always get worse. not like other Abdominal pains. you'll vomit probably. i had my Appendix removed 2 years ago. don't worry, it's not too bad ;).
