This suggested the possible protective role of estrogen in ALS. By conducting treatment of 17β-estradiol to
treated mice, scientists found significantly delay of disease progression.
Coumestrol has been shown to decrease bone resorption and promote the mineralization of bone "in vitro" and "in vivo"; daily injections of coumestrol were shown to reduce bone loss in rats who had undergone an
Esterified estrogens (EEs) (brand names Amnestrogen, Estratab, Estratest, Evex, Femogen, Menest) are synthetic, plant-based estrogens that are manufactured from soybeans and yams. They are used in hormone replacement therapy for menopausal symptoms, female hypogonadism,
, and primary ovarian failure and in the treatment of prostate cancer.
Estrogen deprivation therapy is a form of hormone therapy that is used in the treatment of breast cancer. Modalities include antiestrogens such as selective estrogen receptor modulators (SERMs) like tamoxifen, selective estrogen receptor degraders like fulvestrant, and aromatase inhibitors like anastrozole and
Medical attempts to change homosexuality included surgical treatments such as hysterectomy,
, clitoridectomy, castration, vasectomy, pudic nerve surgery, and lobotomy. Substance-based methods included hormone treatment, pharmacologic shock treatment, and treatment with sexual stimulants and sexual depressants. Other methods included aversion therapy, the reduction of aversion to heterosexuality, electroshock treatment, group therapy, hypnosis, and psychoanalysis.
Thomas Howell Crawford (March 1, 1803 – June 17, 1871) was the thirteenth Mayor of Louisville, Kentucky from April 2, 1859 to April 4, 1861. He was born in Rockbridge County, Virginia. His mother was the first woman to undergo an
, in 1809 in Danville, Kentucky to remove a tumor.
The hospital has particular expertise in the areas of gastroenterology, oncology, orthopaedics and neurology and is fully equipped to undertake laparoscopic investigations of the equine abdomen (e.g. for recurrent or chronic colic) and to perform operative procedures via laparoscopy, e.g.
In female dogs and queens a heat or heat cycle occurs despite spaying as in intact animals. Females often develop pseudopregnancy or pyometra. In addition, in female dogs from ovary remains a granulosa cell tumour with Läufigkeitssymptomen, accretion of the mammary glands, skin problems, bone marrow suppression and endometrial hyperplasia develops. Overall, the syndrome is more common in cats than in dogs, and it is almost exclusively due to surgical errors (incomplete
), ectopic tissue is very rare.
West was working quite successfully as a general practitioner and surgeon in Tonbridge. In 1837 West published in "The Lancet" the first surgery of
, describing how he removed an ovarian cyst with a size of about 20 pints (11.3 liters ). The patient recovered well, and the cyst was placed on display at the Museum of Guy's Hospital. His colleague and friend, John Gorham published a couple of years later several of the ovariotomies made by West.
The endocannabinoid system through CB signaling plays a key role in the maintenance of bone mass. CB is expressed in osteoblasts, osteocytes, and osteoclasts. CB agonists enhance endocortical osteoblast number and activity while restraining trabecular osteoclastogenesis. Another important effect is that CB agonists attenuates
-induced bone loss while increasing cortical thickness. These findings suggest CB offers a potential molecular target for the diagnosis and treatment of osteoporosis.
The 40-bed hospital was the first Catholic hospital in New England. In 1877, the first outpatient department in Boston was established by the hospital in two adjacent houses, followed by the first skin clinic in Boston in 1891. The first abdominal surgery in USA was carried out in the hospital by John Homans in 1882. The same year, the first
in Boston was carried out in Carney by Henry I. Bowditch. The first Catholic nursing school in New England was opened in 1892.
In an experiment by Segers I et al. (2015), the overall maturation rate after IVM of oocytes recovered from
specimens in laboratory was 36%. The maturation rate correlated with the age of patient and duration of IVM. With the 8 couples with embryo cryopreservation, there was a 65% fertilisation rate. At least one good quality day 3 embryo was cryopreserved in 7/8 couples. This experiment shows that IVM of oocytes obtained ex vivo during the processing of ovarian cortex prior to cryopreservation is a promising solution for patients at risk for fertility loss.
Gould and her colleagues found that the ovarian steroid estrogen enhances cell proliferation in the dentate gyrus of the adult rat. This effect can be seen following
and hormone replacement as well as under naturally occurring changes in hormone levels. They discovered that cell proliferation peaks during proestrus, a time when estrogen levels are highest. Also and conversely, steroid hormones of the adrenal glands were found to inhibit cell proliferation in the dentate gyrus but do so indirectly via an NMDA receptor-dependent mechanism.
The menopausal transition, and postmenopause itself, is a natural change, not usually a disease state or a disorder. The main cause of this transition is the natural depletion and aging of the finite amount of oocytes (ovarian reserve). This process is sometimes accelerated by other conditions and is known to occur earlier after a wide range of gynecologic procedures such as hysterectomy (with and without
), endometrial ablation and uterine artery embolisation. The depletion of the ovarian reserve causes an increase in circulating follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels because there are fewer oocytes and follicles responding to these hormones and producing estrogen.
One of the most common elective surgical procedures in animals are those that render animals incapable of reproducing. Neutering in animals describes spaying or castration (also please see castration). To spay (medical term:
or ovario-hysterectomy) is to completely remove the ovaries and often the uterus of a female animal. In a dog, this is accomplished through a ventral midline incision into the abdomen. In a cat, this is accomplished either by a ventral midline abdominal incision, or by a flank incision (more common in the UK). With an
ligatures are placed on the blood vessels above and below the ovary and the organ is removed. With an ovariohysterectomy, the ligaments of the uterus and ovaries are broken down and the blood vessels are ligated and both organs are removed. The body wall, subcutis, and skin are sutured. To castrate (medical term: orchiectomy) is to remove the testicles of a male animal. Different techniques are used depending on the type of animal, including ligation of the spermatic cord with suture material, placing a rubber band around the cord to restrict blood flow to the testes, or crushing the cord with a specialized instrument like the Burdizzo.
Ovariectomies, surgeries inducing menopause, or natural menopause cause fluctuating and decreased estrogen levels in women. This in turn can "attenuate the effects" of endogenous opioid peptides. Opioid peptides are known to play a role in emotion and motivation. β-endorphin (β-EP), an endogenous opioid peptide, content has been found to decrease (in varying amounts/brain region), post
, in female rats within the hypothalamus, hippocampus, and pituitary gland. Such a change in β-EP levels could be the cause of mood swings, behavioral disturbances, and hot flashes in post menopausal women.
Oophorectomy (from Greek ᾠοφόρος, "ōophóros", "egg-bearing" + ἐκτομή, "ektomḗ", "a cutting out of") is the surgical removal of an ovary or ovaries. The surgery is also called
, but this term has been traditionally used in basic science research to describe the surgical removal of ovaries in laboratory animals. Removal of the ovaries in women is the biological equivalent of castration in males; the term castration is only occasionally used in the medical literature to refer to oophorectomy in humans. In the veterinary sciences, the complete removal of the ovaries, oviducts, uterine horns, and the uterus is called spaying and is a form of sterilization.
William James West, was an English surgeon and apothecary, who among other things took a prominent role in the local movement of reform of medical practice. He published in 1837 the first article referred to an
performed in England and first described the picture of a kind of infantile spasm (present in his own son, James Edwin West) in an article published by "The Lancet" in 1841. this syndrome is typically characterized by three findings: epileptic spasms, psychomotor retardation and electroencephalogram with a characteristic layout of hypsarrhythmia, although one of the three may not appear.
The properties of E4 have also been investigated in a series of highly predictive, well validated pharmacological "in vivo" rat models. In these models, E4 exhibited estrogenic effects on the vagina, the uterus (both myometrium and endometrium), body weight, bone mass, bone strength, hot flushes and on ovulation (inhibition). All these effects of E4 were dose-dependent with maximal effects at comparable dose levels. Surprisingly, E4 prevented tumour development in a DMBA mammary tumour model to an extent and at a dose level similar to the anti-estrogen tamoxifen and to
. This anti-estrogenic effect of E4 in the presence of E2 has also been observed in "in vitro" studies using human breast cancer cells.
