Etiology and Evaluation of Sperm Chromatin Anomalies
Evidence suggests that human sperm chromatin anomalies adversely affect reproductive outcomes and infertile men possess substantially amount of sperm with chromatin anomalies than fertile men. Routine semen analysis evaluates parameters such as sperm motility and morphology, but does not examine the nuclear DNA integrity of spermatozoa. It has been suggested that altered nuclear chromatin struc...
متن کاملSex chromatin of hydatidiform moles.
The placenta is a homograft which is tolerated by the host for an unusually long time. The hydatidiform mole may be said to be even more successful in this respect for it can survive longer and penetrate further in the host even in the absence of a viable foetus. Recent observations that a large number of hydatidiform moles are chromatin positive are of much interest, but so far the reported se...

متن کاملSex Chromatin Positive Cells in the Buccal Smears of Normal Newborn Females
Original Article The present study has been conducted on normal 100 newborn females, born at Umaid Hospital, Dr. S. N. Medical College, Jodhpur (Rajasthan). The aim of the study was to find out frequency of sex chromatin positive cells in buccal smear of normal newborn females and their relation with the birth weight. The slides were prepared from the buccal smears and stained by the Carbol Fus...
متن کاملSex Chromatin Frequency Variation among Breast Cancer Patients and Normal Females of Two Reproductive Stages from Bengalee Hindu Females
Original Article X chromosome inactivation refers to the developmentally regulated process of silencing gene expression from all but one X chromosome per cell in female mammals in order to equalize the levels of X chromosome derived gene expression between the sexes. In females, X chromosome inactivation (XCI) begins with the expression of the XIST gene from the X chromosome destined to be inac...
