Cut dahlia (Dahlia Cav.) flowers have recently become popular in Japan, but their marketability is limited by poor vase life. During the postharvest period, senescence of petals initiates from outermost whorl and then proceeds into inner petals. We found that drawing resistances ‘Kokuchou’, ‘Nesshou’, ‘Saisetsu’ decreases with time because gradually detach ovaries. A reduction resistance occurr...

Androgen receptor (AR) modulation in human uteri and ovaries of long term androgen-treated transsexual female patients was investigated. Androgen receptor expression was evaluated immunohistochemically in the ovaries of 11 and the endometria and myometria of six androgen-treated transsexual female patients. This was compared with AR expression in the ovaries and uteri of premenopausal and postm...

Differences in the secretion of estrogens by follicular polycystic ovaries of androgen-sterilized rats and by normal follicular ovaries of early proestrous rats were compared. Some rats were injected i.v. with LH 30 min before bleeding. This injection of LH did not influence the secretion of estrogens by normal ovaries, but greatly increased that by polycystic ovaries, suggesting that there was...

The purpose of the study was to examine the occurrence of programmed cell death (apoptosis) in normal and chromosomally aneuploid testis and ovaries during the second trimester of human development. Such information may be useful in understanding normal and abnormal germ cell development and disorders associated with infertility in adult life. Apoptosis was studied by terminal deoxynucleotidyl ...

The uptake and metabolism of the oostatic pentapeptide analogue of trypsin modulating oostatic factor (TMOF), H-Tyr-Asp-Pro-Ala-Pro-OH (5P), in ovaries of Neobellieria bullata (Parker) (Diptera: Sarcophagidae) were analyzed during their developmental stages. During selected stages of yolk deposition, the fate of [3HPro(3)]5P after its in vivo injection was compared to its uptake after in vitro ...

In the present paper comparative study of morpho-histology of ovaries of both WT (HdrR) and P53 (-/-) of medaka (Oryzias latipes) has been done. The ovaries of adult are paired and oval-rounded in shape and are situated ventrolaterally. Histologically the ovaries consist of follicles with various stages of development, such as primodial follicle, large follicle and growing follicle. Also, the o...

background: congenital toxoplasmosis is one cause of abortion. infection can disrupt ovarian cycles and because toxoplasmosis is an infectious disease may have a similar effect on the ovaries. the purpose of this study was to investigate the pathological changes in the ovaries due to toxoplasmosis.   methods: tachyzoites of toxoplasma gondii were harvested from peritoneal fluid of mice, experim...

Introduction: Genital system is important herd in animal's creation. It is necessary for animal reproduction. Mammal has two sex in genital system such as male and female in separated animals. Animal reproduction destroyed by disorder of genital system. In this case, animals cannot produce an animal similar to them. Finally it cause overthrow a species of animals. Methods: Histomorpholog...

According to their toxicity, toxic heavy metals such as arsenic, mercury, cadmium, copper, zinc, and lead are believed be the most harmful humans, fish, environment. Because levels rising due human activities endangering aquatic species people, current study sought ascertain level of in five catfish parts (skin, liver, muscles, gills, ovaries). In northern part Shatt Al-Arab, samples were colle...

BACKGROUND Cryopreservation of whole ovaries followed by vascular transplantation may improve long-term function in comparison to conventional cryopreservation of ovarian cortex and avascular transplantation. The aim of this study was to assess methods for the evaluation of viability and function of frozen-thawed whole ovaries. METHODS Ewe ovaries were flushed with either cryoprotectant (prop...
