the present study was carried out to characterize the cervical mucus (cm) collected when inseminating holstein cows and to relate the secretion pattern with pregnancy. the mucus was collected from mid-cervix of 64 cows with spontaneus estrus (se) and induced estrus (ie). the quantity, pattern and consistency of the mucus, ph, arborization patterns and the sperm motility were observed. the level...

PURPOSE The prognostic and predictive value of epidermal growth factor receptor (EGFR) expression was evaluated in patients with recurrent breast cancer. EXPERIMENTAL DESIGN The immunohistochemical expression of EGFR was analyzed in 241 patients with recurrent breast cancer. RESULTS EGFR expression was positive in 87 of 241 (36%) patients with recurrent breast cancer, whereas the EGFR expre...

Despite epidemiological evidence supporting a causal relationship between environmental factors and the development of breast and prostatic cancers, direct confirmation is unproven. Differences in hormone profiles in cancer patients and in patients with an increasing number of potential risk factors together with differences n life style and diet, suggest a relationship between diet, hormonal m...

Traumatic brain injury (TBI), typically resulting from vehicle accidents or acts of violence, is a major public health concern. Survivors often face lifelong impairments affecting functional status, memory, cognition, language, and mood, as well as physical functioning and metabolism. Within the past three years, a clear cause and effect has been established – post TBI hormonal deficiency syndr...

OBJECTIVES The aim of this study was to assess the relationship between sex hormones and natriuretic peptide levels in community-based adults. BACKGROUND Women have higher circulating natriuretic peptide concentrations than men, but the mechanisms for these sex-related differences and the impact of hormone therapy are unclear. Experimental studies suggest that androgens may suppress natriuret...

Hormone-dependent disease is an important and prevalent subtype of breast cancer. It is recognized by the presence of a functional estrogen-receptor apparatus, an indolent clinical course, a greater frequency in older women, and clinical responses to the sequential use of hormonal therapies. Antiestrogens, primarily tamoxifen (Nolvadex), have been the mainstay of hormonal therapy for metastatic...

Previous studies suggest that hormonal factors modulate the natural course of psoriasis in women. However, the association of hormonal factors with psoriasis risk has not been assessed using prospective data. We carried out a thorough prospective analysis on the topic in 163,763 women in the Nurses' Health Study I and II. Participants provided information on age at menarche, parity, menopause s...

BACKGROUND The National Institutes of Health (NIH) consensus statement recommends adjuvant therapy for early breast cancer irrespective of age. However, the actual use of such therapy is not well documented among women over 65 years of age. METHODS We studied the frequency of use of adjuvant therapy and report the receipt of this therapy among 200 women aged > or = 65 years diagnosed with ear...

INTRODUCTION In the postmenopausal period, an average of 25% of women will present symptomatic ovarian failure requiring hormonal replacement therapy. Estrogen can relieve vasomotor symptoms. Hormonal replacement therapy is generally not recommended for breast cancer patients due to the potential risk of tumor recurrence. To answer the questions about the safety of hormonal replacement therapy ...
