MicroRNAs comprise a family of small non-coding RNAs that modulate several developmental and physiological processes including pregnancy. Their ubiquitous presence is confirmed in mammals, worms, flies and plants. Although rapid advances have been made in microRNA research, information on stable reference genes for validation of microRNA expression is still lacking. Real time PCR is a widely us...

1-type and biharmonic curves by using laplace operator in lorentzian 3-space arestudied and some theorems and characterizations are given for these curves.

Underwater images often suffer from degradation due to scattering and absorption. With the development of artificial intelligence, fully supervised learning-based models have been widely adopted solve this problem. However, enhancement performance is susceptible quality reference images, which more pronounced in underwater image tasks because ground truths are not available. In paper, we propos...

In order to understand the seismic performance and mechanism of bottom frame seismic wall masonry structure (BFSWMS) and its vulnerability in empirical seismic damage, based on the statistical and numerical analysis of the field seismic damage observation data of 2178 Dujiangyan structures in the Wenchuan great earthquake urban of China on May 12, 2008, a non-linear function model between the s...

background: early detection is a key to survival for gastric cancer. molecular markers such as mirna (microrna) can have great importance in the early diagnosis of gastric cancer. expression of mir-21 and mir-221 are deregulated in many types of human cancers. this study aimed to investigate the differences in mirna expression patterns within the iranian population. methods: total rna was extra...

BACKGROUND Symphysis-fundus measurement is used in pregnancy care to detect poor fetal growth. Symphysis-fundus measurement curves (percentile curves) and prediction of fetuses with a birth weight below the10th percentile have been published previously. The percentile curves show the distribution of symphysis-fundus measurements in the reference population and are recommended as the national st...

Procalcitonin (PCT) levels are elevated early after birth in newborn infants; however, the physiological features and reference of serum PCT concentrations have not been fully studied in preterm infants. The aims of the current study were to establish an age-specific percentile-based reference curve of serum PCT concentrations in preterm infants and determine the features. The PCT concentration...

INTRODUCTION Doppler sonography of the uterine artery (UA) is done to monitor pregnancies, because the detected flow patterns are useful to draw inferences about possible disorders of trophoblast invasion. Increased resistance in the UA is associated with an increased risk of preeclampsia and/or intrauterine growth restriction (IUGR) and perinatal mortality. In the absence of standardized figur...
