Location of the future ovulatory follicle and CL in the same ovary (ipsilateral) or opposite ovaries (contralateral) and number of major follicular waves (two or three) per interovulatory interval (IOI) was studied in 14 heifers. Follicle diameter and a blood sample for progesterone (P4) assay were obtained each day throughout an IOI. Heifers were(More)
Colour Doppler ultrasonography was used to compare the ability of preovulatory follicle (POF) blood flow and its dimensions to predict the size, blood flow and progesterone production capability of the subsequent corpus luteum (CL). Cows (n=30) were submitted to a synchronisation protocol. Follicles ≥7mm were measured and follicular wall blood flow(More)
A 3-d extension of the luteal phase occurs in interovulatory intervals (IOIs) with a contralateral relationship between the corpus luteum (CL) and preovulatory follicle with 3 follicular waves (Contra-3W group). Concentrations of FSH, progesterone, LH, and estradiol-17β for the ipsilateral versus contralateral CL and/or follicle relationship and 2 versus 3(More)
In Survey 1, the records for 196 interovulatory intervals (IOIs) from 24 heifers were used to study the frequency and repeatability for number of follicular waves per IOI and to study the ipsilateral and contralateral relationships between the extant corpus luteum and ovulatory follicle. In Survey 2, 96 IOIs were used from the controls of the previous(More)
Blood samples were collected and follicle diameters were determined daily beginning on Day 12 (Day 0 = ovulation) in 35 interovulatory intervals (IOIs) in heifers. A minor follicular wave with maximal diameter (6.0 ± 0.3 mm) on Day -4 was detected in six of seven IOIs that were scanned for follicles 4 mm or greater. The number of IOIs with a CV-identified(More)
Concentrations of circulating hormones after Day 14 (Day 0 = ovulation) were determined daily in 87 interovulatory intervals (IOIs) in heifers. The IOIs were grouped into four permutations according to an ipsilateral (Ipsi) or contralateral (Contra) relationship between the CL and the preovulatory follicle and two (2W) or three (3W) follicular waves per(More)
On Day 16 (Day 0 = ovulation) or before the expected transition into the luteolytic period, heifers were not treated (control group, N = 7) or were treated with a single 0.1-mg dose of estradiol (E2) (E2 group, N = 6) or E2 combined with the GnRH antagonist acyline (E2/Ac group, N = 5). Hourly blood samples were collected from hour of treatment (Hour 0) to(More)
Follicular Wave 1 and 2 and the associated FSH Surge 1 and 2 were used to designate the first two waves and surges of the interovulatory interval in two experiments in heifers. In experiment 1, a group with early (group E, N = 9) and late (group L, N = 5) development of the dominant follicle of Wave 1 were used as natural models to study FSH/follicle(More)
Diameter of follicles was determined every 12 hours and progesterone (P4), FSH, and LH concentrations were determined every 6 hours from Day 12 (Day 0 = ovulation) to the ovulation at the end of the interovulatory interval (IOI). Groups were assigned on the basis of an ipsilateral (Ipsi) versus contralateral (Contra) relationship between the preovulatory(More)
PURPOSE To evaluate the concentration of copper and iron in the aqueous humour of steroid-treated eyes, particularly to study the concentration of these metals in relation to steroid-induced increases in intraocular pressure (IOP). METHODS Adult rabbits of both sexes were selected in order to study the effect of steroids on the concentrations of copper(More)
