31 Klinefelter syndrome is still the most common chromosomal disease, balanced translocation accounts for largest proportion of autosomal abnormality.

32 Objective To show the impaction of chromosomal abnormalities on abortion, mental retardation, primary amenorrhea by chromosome exam.

33 RESULTS:The results of sperm morphology rates, the sperm chromosomal aberration test and the bone marrow micronucleus rates were negative.

34 Methods: The chromosomal G banded karyotypes of 37 cases with primary amenorrhea were analyzed.

35 Of all the chromosomal aberrations, the appearance of asynapitc univalent and resultant pollen abortion was the major cause of seedless fruits.

36 The chromosomal complement of Bactrian Camel has been studied by means of peripheral blood lymphocytes culture.

37 Intersexuality is the condition of persons born with a significantly atypical development of their sex organs or with certain chromosomal irregularities.

38 Studies on the chromosomal morphology and banding pattern in Beta vulgaris L.

39 Objective:To investigate whether high mobility group box chromosomal protein 1(HMGB1) can activate macrophages to secrete IL-18.

40 The NBS1 is a component of the MRE11/RAD50/NBS1 complex (MRN) and plays a critical role in the DNA double strand break (DSB) repair and the maintenance of chromosomal integrity.

41 Methods The changes of aberration yields induced by different radiators were determined using chromosomal aberration assay in both bone marrow cells and spermatogonia.

42 Objective To observe chromosomal aberrations and micronucleus in peripheral blood lymphocyte.

43 The site is about the some general properties and a chromosomal display of Methanococcus jannaschii DSM2661.

44 Aberrance of the Chromosomal in 20 patients ( 3.7 % in 545 patients ) .

45 Reduction of chromosome number and decrease in chromosomal aberration rate.

46 Mitochondrial Eve is the female counterpart of the Y - chromosomal Adam, the patrilinear most recent common ancestor.

47 Through comparative analysis, the chromosomal aberration rate of 13 Jinnan stud bulls is in normal range in this study.

48 The molecular mechanism for chromosomal aberration and micronuclei induced by holmium ions was most probably DNA breakage to root-tip cells of vicia faba.

49 In mammalian species, a variety of chromosomal rearrangements are known to exist.

50 Conclusion: Long-term and low dose can induce the increase of the rate of chromosomal aberration in radioactive working personnel.

51 Objective : to assess the relationship between azoospermia or severe oligozoospermia and Y chromosomal microdeletions.

52 There have been recent advances in methods aimed at mapping chromosomal regions.

53 Conclusion:Maternal serum PAPP-A might be a marker for predicting fetal chromosomal anomaly.

55 Objective : To study the chromosomal aneuploid incidence of severe oligozoospermia spermatozoa.

56 Objective: To establish a new,[http://sentencedict.com/chromosomal.html] rapid and clinical practical molecular cytogenetic method for diagnosing the chromosomal diseases as well as guiding aristogenesis and prenatal diagnosis.

57 In Ames test, micronucleus and chromosomal aberration assay BaCl 2 showed negative results.

58 No difference was observed in chromosomal number, relative length and chiasma location.

59 There is a weak but fairly convincing association between chromosomal abnormalities such as trisomy 21 (Down syndrome) and echogenic foci in the heart.

60 Methods:In 4 cases of acute radiation injury, radiodosages were estimated, clinical manifestation, laboratory examination results and chromosomal aberration rates were compared and analysed.
