The locomotion of Caenorhabditis elegans consists of forward crawling punctuated by spontaneous reversals. To better understand the important variables that affect locomotion, we have described in detail the locomotory behavior of C. elegans and identified a set of parameters that are sufficient to describe the animal's trajectory. A model of locomotion based on these parameters indicates that ...

Abstract Background: Breast cancer is the most common fatal cancer among women worldwide and it has an increasing rate in Iranian women. The aim of this study was to determine the relationship of gravidity with removed lymph nodes and involved lymph nodes after mastectomy surgery in women with breast cancer. Methods: In this ...

Background Pseudoxanthoma elasticum (PXE) is a genetic multisystem disorder characterized by calcified dystrophic elastic fibres in skin, retina and arteries. Much of the earlier literature on pregnancy in PXE contained reports of severe complications, leading some healthcare providers to advise women with PXE against becoming pregnant and some women with PXE to avoid pregnancy. Objectives To e...

A 355 g male fetus was aborted at gestation age of 17 weeks and 6 days by a 31 years old healthy woman with her first gravidity at Haidian Maternal and Children Health Hospital. An ultrasound scan showed no anomaly at 12th gestational weeks (GWs). Down syndrome screening test showed a high risk of open neural tube defects at 16th GW. Three‐dimensional ultrasound scan indicated an irregular anec...

background : adenomyosis is a common benign disorder in premenopausal women. it may be presents with uterus enlargement, pelvic pain, abnormal uterine bleeding and dysmenorrheal. the main objective of this study was to assess prior uterine surgery was a risk factor for adenomyosis. materials and methods: in this cross-sectional study, we reviewed the medical records of all women who underwent h...

Many techniques commonly used by herpetologists for monitoring amphibian populations and communities yield censuses of the total adult population size (N). However, for many studies, e.g., of reproductive output, development of populations and potential for evolutionary changes, the effective population size (Ne) must be known. While modern molecular techniques make it possible to measure Ne, t...
