the objectives of the present study were to investigate the prevalence of histologic thyroids lesions and the respective thyroid hormones changes of ewes in an endemic goiter region and to find out any impact of this condition on the fetal thyroid structures and serum thyroid hormones. in the present study a total number of 100 pregnant ewes and their fetuses slaughtered at slaughterhouse were ...

Mutant Ts/+ fetuses are developmentally retarded as compared to normal +/+ littermates. Mutant fetuses have less total hemoglobin than do normal fetuses of the same gestational age. However, when compared to +/+ fetuses of similar body weight, Ts/+ fetuses have the appropriate amount of total hemoglobin, suggesting that the apparent anemia observed in mutant fetuses is most likely the result of...

OBJECTIVE The objective of this study is to measure aortic intima-media thickness (aIMT) and aortic diameter (AD) in appropriate for gestational age (AGA) fetuses, small for gestational age (SGA) fetuses, and intrauterine growth restricted (IUGR) fetuses. METHODS Case-control study performed between June 2011 and June 2012. Forty-nine AGA fetuses, 40 SGA fetuses, and 35 IUGR fetuses underwent...

Small fetuses constitute a large heterogenous group that includes healthy small fetuses, chromosomally abnormal fetuses and fetuses suffering from utero-placental insufficiency leading to restriction in fetal growth. This review outlines the diagnosis of intra-uterine growth restriction and describes how to differentiate this group from the group of healthy small fetuses. This is very crucial i...

BACKGROUND: Neospora caninum is an apicomplexan protozoa,which causes abortion in cattle worldwide. OBJECTIVES:The present study was designed to estimate the rate oftransplacental transmission of N.caninum to aborted fetuses inseropositive dams in dairy farms in Mashhad area, Iran.METHODS: Two hundred blood samples of dam with abortedbovine fetuses were collected from dairy farms from 2008 to20...

Objective(s): End-stage hepatic failure is a potentially life-threatening condition for which orthotopic liver transplantation is the only effective treatment. However, a shortage of available donor organs for transplantation each year results in the death of many patients waiting for liver transplantation. Xenotransplantation, or the transplantation of cells, tissues, or organs between differe...

BACKGROUND Tissue Doppler Imaging (TDI) is a sensitive index of myocardial function. Its role in the fetus has not been extensively evaluated. OBJECTIVE To compare myocardial tissue Doppler velocities in fetuses with hypoplastic left heart syndrome (HLHS) to those of normal fetuses (matched for gestational age.) METHODS Cross-sectional retrospective study conducted at 2 large perinatal cent...

conclusion the low prevalence of the nb absence in normal fetuses in the present study is compatible with the larger size of the nb in iranian people compared to other communities. meanwhile, the reference range of the nb length in normal iranian fetuses was established so that basic data could be recorded for further studies regarding the absence or presence of the nb in screening for chromoso...
