in order to evaluate the efficiency of biocontrol agents of corn stem borer ,ostrinia nubilalis, experiment was conducted in a randomized complete block by five treatments and four replication, including, indoxacarb (avant)®, trichogrammawasps, bacillus thuringiensis var: kurstaki, integration of trichogramma sp. and bt., and control as treatments number 1 to 5. in treatments with parasitoid re...
Introduction: Angiogenesis is regarded as a complex activity required for physiological process as well as many pathological conditions as solid tumor progression and metastasis. Stachys Lavandulifolia of Laminacea family prossesses antioxidant and anti-apoptosis effects. Therefore, this study aimed to investigate the effect of Stachys Lavandulifolia alcoholic extract on angiogenesis in chorioa...
BACKGROUND While live birth is the principal clinical outcome following in vitro fertilization (IVF) treatment, the number of eggs retrieved following ovarian stimulation is often used as a surrogate outcome in clinical practice and research. The aim of this study was to explore the association between egg number and live birth following IVF treatment and identify the number of eggs that would ...
An experiment was conducted to determine the effect of time of oviposition, generally representing different positions in the normal egg laying sequence, on egg weight loss during storage and incubation, and on fertility and fertile hatchability of eggs from mid-lay (42 wk) and old (67 wk) broiler breeders. A total of 1,800 eggs (900 eggs per flock age) were collected during 10 consecutive days...
the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
Reproductive potential was assessed for stable fly cohorts fed cattle, chicken, or horse blood. Flies provided chicken blood oviposited 20% more eggs per day than did those fed cattle or horse blood. However, flies provided cattle or horse blood were fecund 50% longer. When both egg viability and number of eggs produced were considered, lifetime reproductive potential was almost twice as high f...
Introduction: Angiogenesis is the formation of new vessels from early vessels that has effected in pathologic condition such as growing tumor, metastases, arthritis rheumatoid, diabetes and physiologic condition such as developmental and growing of organ regeneration, wound healing, and reproduction. Otostegia presica is a member of Laminacea family, has antioxidant and anti-apoptosis propertie...
in order to evaluate the waterlogging stress effects on yield and yield components of rapeseed, a pot experiment was conducted at gorgan university of agricultural sciences and natural resources during 2010-2011. the experiment design was completely randomized with factorial arrangement and three replications. examined factors were developmental stage (seedling, stem elongation, flowering and g...
S OF PAPERS 253 145 Effects of Originial XPC on performance of layers. K. E. Anderson1 and J. Frank*2, 1North Carolina State University, Raleigh, 2Diamond V, Cedar Rapids, IA. Laying hens (11 white and 7 brown strains; approximately 17 weeks of age; n = 9594) were utilized in a 16 week study to determine the effect of Saccharomyces cerevisiae fermentation product (Original XPC) on hen day and h...
