Salivary, mammary and prostate glands are sex hormone-dependent organs sharing common aspects in structure, hormonal responsiveness and tumor histopathology. Salivary tumors (especially the malignant types) are not as ...

Transgenic (TG) mice expressing human chorionic gonadotropin (hCG) beta-subunit under the ubiquitin C promoter, presenting with a moderately elevated level of LH/hCG bioactivity develop multiple neoplasms secondary to the ...

Environmental chemicals may be involved in the etiology of breast cancer. There is substantial evidence that breast cancer risk is associated with prolonged exposure to female hormones. Among these hormonal influences a ...

The postlactational involution of the mammary gland is a complex process. It involves the collapse of the alveoli and the remodeling of the extracellular matrix, which in turn implies a complex set of interrelations between ...

1. The in vivo effect of estradiol and domperidone (a hypophysis stimulator of prolactin secretion) in immature ovariectomized-adrenalectomized and hypophysectomized rat mammary gland was studied. 2. γ-Glutamyltranspeptidase ...

Mammary tumors are very common in female dogs and its prognosis varies significantly according to the tumor invasion degree. Myoepithelial layer destruction is considered a differential diagnosis parameter of in situ from ...

Background: Ultrasound allows the udder evaluation of lactating cattle, through parameters such as the area of the cistern of the mammary gland and teat, and can reveal structures with different echogenicity, indicating ...
