follicular dendritic cells or dendritic reticulum cells are important components of the immune system essential for antigen presentation. malignancies arising from these cells are uncommon and the first case was reported in 1986. the most common sites of follicular dendritic cell sarcomas are lymph nodes, especially cervical, axillary and mediastinal regions, but extranodal sites including head...

this study was conducted to evaluate histochemical alterations of river buffalo’s uterine wall acid andalkaline phosphatases (alp and acp), lipase and carbohydrate ratio during follicular and luteal phases.forty apparently healthy and non pregnant river buffalos were considered for removal of the uterus aftersacrifice in slaughterhouse. all dissected uteri were divided into two luteal (by obser...

It is very difficult to differentiate follicular adenoma from follicular carcinoma in thyroid follicular lesions. The authors investigated the biological behavior of these thyroid follicular lesions using immunohistochemical techniques. Specimens taken from normal thyroid, 2 cases; follicular adenoma, 9; atypical adenoma, 7; and follicular carcinoma, 8; were observed. Proliferating cell nuclear...

In recent years chaotic secure communication and chaos synchronization have received ever increasing attention. Unfortunately, despite the advantages of chaotic systems, Such as, noise-like correlation, easy hardware implementation, multitude of chaotic modes, flexible control of their dynamics, chaotic self-synchronization phenomena and potential communication confidence due to the very dynami...

Four patients are described in whom a follicular carcinoma developed following thyroidectomy for a benign follicular neoplasm. It is possible that the initial thyroid neoplasm was a well- differentiated follicular carcinoma which was microscopically indistinguishable from a benign adenoma. Realizing this pathologic pitfall in thyroid diagnosis, the need for meticulous examination of the pa...

The effect of gonadotropin releasing hormone (GnRH) treatment on the time of ovulation and the occurrence of follicular dominance during the non-breeding and breeding seasons (experiment 1), and on fertility after artificial insemination (AI) in the non-breeding season (experiment 2), was examined in Merino ewes. Oestrus was synchronized in 40 nulliparous ewes (experiment 1; n = 20, in the non-...

Two experiments evaluated the influence of altering the concentrations of progesterone during the development of the ovulatory follicle on the composition of the follicular fluid, circulating LH and PGF(2α) metabolite (PGFM), and expression of endometrial progesterone receptor and estrogen receptor-α. In both experiments, the estrous cycles were presynchronized (GnRH and progesterone insert fol...

The aim of the present study was to develop a treatment protocol for the precise synchronization of oestrus that would avoid the development of persistent dominant ovarian follicles. Bos indicus heifers, in which oestrous cycles had been presynchronized, were allocated randomly, according to the day of their oestrous cycle, to one of five treatment groups. All heifers received a subcutaneous ea...

two experiments were performed to determine the effectiveness of different progestogens contained in intravaginal devices, different doses of ecg and subsequent hcg treatment on the reproductive performance of estrus-induced mature lori ewes. in the first experiment, 88 ewes were allocated into two groups, and were treated with either fluorogestone acetate (fga) sponges or controlled internal d...

the aim of this study was to analyze the incidence of stage of embryonic development, embryo quality and the time of transfer on pregnancy rate in embryo transfer program timed. we were worked a total of 23holsteincowsasembryo donors, super-ovulated with gonadotropin of pregnant mare serum (pmsg) (2500 3000ui).69 cows were used as recipients of holstein dairy heifers with an age of20 months and...
