Plant architecture is commonly defined by the adjacency of organs within the structure and their properties. Few studies consider the effect of endogenous temporal factors, namely phenological factors, on the establishment of plant architecture. This study hypothesized that, in addition to the effect of environmental factors, the observed plant architecture results from both endogenous structur...

Ovarian hyperstimulation syndrome (OHSS) is a severe complication of ovarian stimulation for assisted reproductive techniques. Clinical manifestations are massive extravascular fluid accumulation and haemoconcentration. Vascular endothelial growth factor (VEGF) has been demonstrated to mediate the development of OHSS. Intravenous albumin at the time of oocyte aspiration has been suggested as an...

In female rats, in uteroexposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) during critical periods of organogenesis causes a permanent thread of tissue, consisting of a core of mesenchyme surrounded by keratinized epithelia, across the vaginal opening. The objective of the current study was to determine the earliest time after exposure to TCDD during fetal development that morphological cha...

The objective of this study was to examine the impact of polymorphisms in the acyl-CoA:diacylglycerol acyltransferase (DGAT1), leptin and growth hormone receptor genes on body energy (body condition score, total body energy content and cumulative effective energy balance) and blood metabolic traits (levels of beta-hydroxybutyrate, glucose and non-esterified fatty acids), measured once before th...

In a plant, the progression from vegetative growth to reproductive growth is called the floral transition. Over the past several decades, the floral transition has been shown to be determined not by a single gene but by a complicated gene network. This important biological process, however, has not been investigated at a genome-wide network level. We collected Arabidopsis (Arabidopsis thaliana)...

Assisted reproductive technologies (ARTS) are used for more than 30 years to help infertile couples. Concerns about long-term health of children conceived following ART have led to start follow-up studies. Despite methodological limitations and discrepant results, many of the studies and meta-analyses have reported an increased risk of birth defects after ART. Etiologies may be multiple births,...

Purpose. To investigate whether the addition of antibiotic/antimycotic during human granulosa-lutein cells (GLCs) isolation and cell-plating procedures prevents microbial contamination after 144 h of culture and also evaluate the effects of contamination on GLCs ultrastructure and steroid secretion. Methods. GLCs obtained from five women submitted to assisted reproductive techniques (ARTs) were...

Body size and temperature are the two most important variables affecting nearly all biological rates and times, especially individual growth or production rates. By favoring an optimal maturation age and reproductive allocation, natural selection links individual growth to the mortality schedule. A recent model for evolution of life histories for species with indeterminate growth, which include...
