Association of soybean-based extenders with field fertility of stored ram (Ovis aries) semen: A randomized double-blind parallel group design
(2013)Two consecutive randomized double-blind field fertility experiments were conducted over a 4-month period and aimed at evaluating the association of two commercial soybean lecithin-based extenders (AndroMed [Minitub, ... -
A brief exposure to low pH prior to refrigerated storage reduces the motility and viability of goldfish sperm (Carassius auratus, Linnaeus, 1758)
(2015)Optimal conditions of short-term storage of fish sperm are important for successful artificial reproduction protocols or incubation of sperm in a cryoprotecting medium for successful sperm cryopreservation. The influence ... -
Current and future status of ovulation induction in polycystic ovary syndrome
(1997)Great progress has been achieved during the last 20 years in the field of ovulation induction in patients with polycystic ovary syndrome (PCOS). Clomiphene citrate remains the first line of treatment for all anovulatory ... -
Effect of plasmin, plasminogen activators and a plasmin inhibitor on bovine in vitro embryo production
(2008)In the present study, four experiments were conducted to investigate the possible effects of plasminogen activators (urokinase-type plasminogen activator (u-PA) and tissue-type plasminogen activator (t-PA)), plasmin, and ... -
Effect of porcine and ovine FSH on nuclear maturation of pig oocytes in vitro
(2008)The effect of porcine or ovine FSH on the maturation rate of porcine oocytes and on the time course of meiotic progression was studied. Groups of 20 grade-A cumulus oocyte complexes, aspirated from slaughterhouse cycling-gilt ... -
Estradiol and leptin as conditional prognostic IVF markers
(2005)We studied the concentration of serum estradiol and serum and follicular fluid leptin in 200 women undergoing their first in vitro fertilization with embryo transfer (IVF-ET) program at the time of human chorionic gonadotrophin ... -
How apple responds to boron excess in acidic and limed soil
(2013)Two year-old apple plants (Malus domestica cv. Red Chief Delicious) were grown in an acidic and limed soil, and fertilized with B (0, 1, 3 and 5 mg kg(-1) soil). Fresh matter weight of plants was positively correlated with ... -
Induction of the acrosome reaction in bull spermatozoa with plasmin
(2003)Proteolytic enzymes appear to have an essential role in multiple phases of mammalian fertilization. Plasmin, the active enzyme of the plasminogen activation system that stimulates fibrinolysis and proteolysis has a less ... -
Modulating effect of leptin on basal and follicle stimulating hormone stimulated steroidogenesis in cultured human lutein granulosa cells
(2009)Background: In vitro data have shown conflicting results in terms of the effect of leptin on granulosa cells steroidogenesis. Aim: The aim of the present study was to investigate the effect of low and high doses of leptin ... -
Progesterone concentration as an indicator of ovarian response to superovulation in Chios ewes
(2002)We investigated the prediction of the ovarian response to superovulation using progesterone (P-4) determination in Chios ewes. During the estrus period, estrus synchronization and multiple ovulations were induced in 100 ... -
Ram seminal plasma and fertility: Results from an ongoing field study
(2000)The effects of partial replacement of ram semen diluent with ram seminal plasma on the fertility of ewes were studied. Crossbred Chios ewes (n = 152) were assigned to six groups. The oestrous cycles of the ewes were ... -
Relationships between nitrogen, dry matter accumulation and glucosinolates in Eruca sativa Mills. The applicability of the critical NO3-N levels approach
(2012)Rocket salad (Eruca sativa Mills) is one of the major leafy vegetables produced worldwide and has been characterized as a rich source of chemoprotective glucosinolates (GSL). The relationship between N fertilization and ...
