Flowering plants possess specialized extracellular matrices in the female organs of the flower that support pollen tube growth and sperm cell transfer along the transmitting tract of the gynoecium. Transport of the pollen tube cell and the sperm cells involves a cell adhesion and migration event in species such as lily that possess a transmitting tract epidermis in the stigma, style, and ovary....

Nodular histiocytic/mesothelial hyperplasia (NHMH) is a very rare condition. It generally thought to be associated with repeated mechanical or chemical stimulation. This study reported NHMH papillary growth pattern in the ovary following high-intensity focused ultrasound (HIFU) treatment for uterine leiomyoma and adenomyosis. A 48-year-old female, who had history of undergoing HIFU 7 times aden...

The 3D internal structure microscopy (3D-ISM) was applied to the equine ovary, which possesses peculiar structural characteristics. Stereolithography was applied to make a life-sized model by means of data obtained from 3D-ISM. Images from serially sliced surfaces contributed to a successful 3D reconstruction of the equine ovary. Photopolymerized resin models of equine ovaries produced by stere...

The ontogeny of Criconema octangulare (Cobb, 1914) Taylor, 1936, is examined and shows ovary development and body length to be of primary importance in differentiating its life-cycle stages. Second-stage juveniles can be identified by body length and ovary length. The third stage can be distinguished from the second by longer body and ovary length, and from the fourth by a shorter ovary. The fo...

Polycystic ovary syndrome is an endocrine disorder affecting 1 in 10 women. Women with polycystic ovary syndrome can experience co-morbidities, including depressive symptoms. This research explores the experience of living with polycystic ovary syndrome and co-morbidities. Totally, 10 participants with polycystic ovary syndrome took part in Skype™ interviews and analysed using thematic analysis...

The constitutive secretory pathway has been reconstituted in mechanically permeabilized Chinese hamster ovary cells using two secretory markers, an acyltripeptide (N-octanoyl-Asn-Tyr-Thr-NH2) that is glycosylated at Asn in the endoplasmic reticulum and a truncated ceramide that is converted to sphingomyelin. Secretion of these bulk phase markers is dependent on cytosolic proteins and ATP. Secre...

Gene dosage plays a critical role in a range of cellular phenotypes, yet most cellular expression systems use heterologous cDNA-based vectors which express proteins well above physiological levels. In contrast, genomic DNA expression vectors generate physiologically-relevant levels of gene expression by carrying the whole genomic DNA locus of a gene including its regulatory elements. Here we de...

The ovary receives a finite pool of follicles during fetal life. Atresia remains the major form of follicular expenditure at all stages since development of ovary. The follicular reserve, however, declines at an exponential rate leading to accelerated rate of decay during the years preceding menopause. We examined if diminished follicle reserve that characterizes ovarian aging impacts the attri...

Recent investigations of sensory and behavioral cues that initiate sexual selection processes in the squid Loligo pealeii have determined that egg capsules deposited on the substrate provide a strong visual and chemotactile stimulus to males, even in the absence of females (1, 2, 3). The visual stimulus of egg capsules attracts males to the eggs, and when the males touch the eggs, they encounte...

This study investigated whether undifferentiated germ and/or somatic stem cells remain in the differentiated ovary of a species that does not undergo sex changes under natural conditions and retain their sexual plasticity. The effect of aromatase inhibitor (AI)-treatment on sexually mature female zebrafish was examined. A 5-month AI treatment caused retraction of the ovaries after which testes-...
