rested on sociocultural theory (sct), this study attempted to examine the effect of written corrective feedback (wcf) followed by producing written languaging on developing writing accuracy over new tasks. to this aim, two intact iranian efl classes at the low-intermediate level were randomly assigned to two experimental groups: direct (n = 25) and indirect (n = 25). both groups wrote on a numb...
this study investigated the effects of planning on second-language written production with regard to task type. the participants were 75 iranian learners of english as a foreign language attending a private foreign language institution. they were asked to complete two different types of writing tasks (expository writing task and argumentative writing task) in different planned conditions (indiv...
Progesterone is essential for maintaining pregnancy, and several authors have suggested that low peripheral concentrations of progesterone may be responsible for high rates of embryonic loss. The primary organ involved in the catabolism of progesterone is the liver, and cytochrome P450 2C and 3A sub-families account for a large proportion of this catabolism. Elucidating a mechanism to decrease ...
objective(s)progesterone is a steroid hormone whose biology has been greatly studied within the confines of reproductive function. in recent years, the neuroprotective effects of progesterone have attracted growing interest. glial cell line-derived neurotrophic factor (gdnf), is a neurotrophic factor which plays a crucial role in the development and maintenance of distinct sets of central and p...
Evaluation of a new chemiluminescent enzyme immunoassay, the PATHFAST assay system (PATHFAST), for measurement of circulating progesterone in mares was performed. Five mares at the mid-luteal stage were administrated a single i.m. injection of prostaglandin F2α analog (PGF2α; cloprostenol 250 μg/ml), and then blood samples were collected from the jugular vein at 0, 15, 30 and 45 min, at one-hou...
background: the aim of this study was to evaluate the relationship between ultrasonographic findings and serum progesterone and cancer antigen-125 (ca-125) levels in threatened miscarriage and to predict pregnancy outcome. materials and methods: in a prospective comparative case-control study, serum ca-125 and progesterone levels were measured for 100 pregnant women with threatened miscarriage ...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
introduction: following a traumatic brain injury (tbi), the excessive release of proinflammatory cytokines is major cause of cerebral edema that can cause permanent neuronal loss. this study examined the changes in brain concentrations of proinflammatory cytokines il-1, il-6, tnf-α and tgf- after different doses of estrogen or progesterone treatment in brain-injured rats at 6 and 24 h post-in...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
BACKGROUND Hypoluteoidism in the bitch is characterized by insufficient production and secretion of progesterone by the corpora lutea. It is a rare pathologic condition and during pregnancy, it leads to embryonic resorption or fetal abortion. Supplementary therapy with progestins is indicated during pregnancy to obtain delivery of vital puppies but unwarranted side effects of such treatment are...
