background: ovarian immature teratoma is a very rare type of tumor associated with a high relapse rate and mortality. correspondingly, early diagnosis is important for effective treatment. the goal of this study was to retrospectively analyze the ultrasound characteristics of 11 cases of immature teratomas. materials and methods: between january 2002 and december 2010, 11 patients were diagnose...

the objective of this study was evaluation of excessive pregnancy weight gain effect in non-diabetic women with normal pre-pregnancy bmi on macrosomia of neonate. in a descriptive cross-sectional study, neonate weighs of all term pregnancy in non-diabetic women with normal pre-pregnancy bmi delivered from 2002 to 2004 in shaheed sadoughi hospital in yazd, were evaluated. compared with mothers w...

there are now several tests available that can assess fetal status. a series of 164 cases of high risk pregnancies were studied in order to assess predictive value of a nonstress test. the majority (36%) of patients complained about postdate pregnancy. a nonreactive test was identified in 24 of the patients (14.6%). fetal distress, low apgar score in 1 and 10 minutes after birth and mean of apg...

conclusions acupressure at both acupoints reduced anxiety level and increased maternal-fetal attachment. this method can be easily used in the delivery room. results the results revealed no significant difference among the three groups regarding the anxiety level before the intervention (p > 0.05). one hour after the intervention, this measure was significantly lower in the intervention groups ...

Background: Fetal electrocardiography is a developing field that provides valuable information on the fetal health during pregnancy. By early diagnosis and treatment of fetal heart problems, more survival chance is given to the infant.Objective: Here, we extract fetal ECG from maternal abdominal recordings and detect R-peaks in order to recognize fetal heart rate. On the next step, we find a be...

The microenvironment is a key regulator of hematopoietic stem cells (HSCs) and is a likely source of extracellular factors that control stem cell fate. A better understanding of these microenvironmental factors may come from investigations of developmental cell fate determination in which the critical roles of cell-cell interactions of multipotential cells have been shown. The Wnt gene family i...

Gene expression is the most fundamental level at which the genotype leads to the phenotype of the organism. Enabled by ultra-high-throughput next-generation DNA sequencing, RNA-Seq involves shotgun sequencing of fragmented RNA transcripts by next-generation sequencing followed by in silico assembly, and is rapidly becoming the most popular method for gene expression analysis. Poly[A]+ RNA-Seq a...

During development, thymocytes express a number of genes typical for activated peripheral T lymphocytes, including granzymes. We have now analyzed by reverse transcription-polymerase chain reaction (RT-PCR), immunohistochemistry, and cytochemistry fetal liver cells and thymocytes at various developmental stages for the expression of granzyme A-G genes. At days 13-17 of gestation, only granzyme ...
