Cesarean delivery is a frequent, easily obtainable, and meaningful event in obstetrics that has frequently been used as a quality indicator. However, its utility as a widespread marker of quality has several limitations. The cesarean delivery rate does not account for variation in levels of maternal care with varying maternal and fetal conditions. Attempts to risk adjust with the nulliparous, s...

Background: Rice seed proteins are lacking essential amino acids (EAAs). Genetic engineering off ers a fast and sustainable method to solve this problem as it allows the specifi c expression of heterologous EAA-rich proteins. The use of selectable marker gene is essential for generation of transgenic crops, but might also lead to potential environmental and food safety problems...

Quality of an oocyte’s cytoplasm is an important factor affecting preand postimplantation development of the future embryo. It can be compromised for example by aging, both maternal (i.e. related to the female's age) and postovulatory (i.e. related to the time between ovulation and fertilization). Recently, we have establish a new non-invasive method to assess cytoplasmic quality of fertilized ...

Tumour markers are substances that are produced either by the tumour itself or by the body in response to the presence of cancer or certain benign conditions that can aid in the diagnosis of cancer. The subject of tumour markers is a broad one, and there is an abundance of data. A literature review of potential molecular markers relevant to oral neoplasia was undertaken in terms of a perspectiv...

background: inhibin is a dimeric glycoprotein that has a depressive effect on the anterior hypophyse secretion. the level of this tumor marker is undetectable in menopause women. in patients with gynecological cancer, especially granulosa and epidermal-type (mucinous), ovarian cancers considerable increase in the serum level of inhibin has been reported. the increased level of inhibin has been ...

a greenhouse experiment was conducted in 2013 in research lab of karaj islamic azad university to determine the yield and activity of chemical markers as the response to different concentrations of cadmium (cd) (0, 5, 10 and 20 mg of cd/kg of soil) in wheat cultivars (karaj 1 and karaj 2). treatments were tested in a factorial experiment with four replications in 7.5 kg plastic pots. the respon...

objective: to evaluate whether systemic inflammatory markers (neutrophil to lymphocyte ratio (nlr), platelet to lymphocyte ratio (plr) and red blood cell distribution width (rdw) to platelet ratio (rpr)) can be used as reliable markers for the diagnosis of premature ovarian insufficiency (poi) and to determine if there is a relationship between these markers and follicle stimulating hormone (fs...

background: the availability of testis specific genes will be of help in choosing the most promising biomarkers for the detection of testicular sperm retrieval in patients with non-obstructive azoospermia (noa). testis specific chromodomain protein y 1 (cdy1) is a histone acetyltransferase which concentrates in the round spermatid nucleus, where histone hyperacetylation occurs and causes the re...

To investigate the effects of sagging shifts of three on-board kV imaging systems (OBI) on the isocenter positioning accuracy and image quality of cone-beam CT (CBCT). A cubical phantom having a metal marker in the center that can be aligned with the radiation isocenter was used to measure sagging shifts and their variation with gantry angle on three Varian linacs with kV on-board imaging syste...
