Ureteral cancerUreteral cancer is cancer of the ureters, muscular tubes that propel urine from the kidneys to the urinary bladder. It is also known as ureter cancer, renal pelvic cancer, and rarely ureteric cancer or uretal cancer. Cancer in this location is rare. Ureteral cancer becomes more likely in older adults, usually ages 70–80, who have previously been diagnosed with bladder cancer. Ureteral cancer is usually a transitional cell carcinoma. Transitional cell carcinoma is "a common cause of ureter cancer and other urinary (renal pelvic) tract cancers.
UrogynecologyUrogynecology or urogynaecology is a surgical sub-specialty of urology and gynecology. In 1893, Howard Kelly, a gynecologist and pioneering urogynecologist, invented an air cystoscope which was simply a handheld, hollow tube with a glass partition. When the American Surgical Society, later the American College of Surgeons, met in Baltimore in 1900, a contest was held between Howard Kelly and Hugh Hampton Young, who is often considered the father of modern urology.
European rabbitThe European rabbit (Oryctolagus cuniculus) or coney is a species of rabbit native to the Iberian Peninsula (Spain, Portugal and Andorra), western France, and the northern Atlas Mountains in northwest Africa. It has been widely introduced elsewhere, often with devastating effects on local biodiversity. Its decline in its native range due to myxomatosis, rabbit hemorrhagic disease, overhunting and habitat loss has caused the decline of the Iberian lynx (Lynx pardinus) and Spanish imperial eagle (Aquila adalberti).
FistulaA fistula (plural: fistulas or fistulae -li,_-lai; from Latin fistula, "tube, pipe") in anatomy is an abnormal connection between two hollow spaces (technically, two epithelialized surfaces), such as blood vessels, intestines, or other hollow organs. Types of fistula can be described by their location. Anal fistulas connect the anal canal and the perianal skin. Anovaginal or rectovaginal fistulas occur when a hole develops between the anus or rectum and the vagina. Colovaginal fistulas occur between the colon and the vagina.
EjaculationEjaculation is the discharge of semen (the ejaculate; normally containing sperm) from the male reproductive tract as a result of an orgasm. It is the final stage and natural objective of male sexual stimulation, and an essential component of natural conception. Ejaculation can occur spontaneously during sleep, and is a normal part of human sexual development (a nocturnal emission or "wet dream"). In rare cases, ejaculation occurs because of prostatic disease. Anejaculation is the condition of being unable to ejaculate.
HydrogelA hydrogel is a biphasic material, a mixture of porous, permeable solids and at least 10% by weight or volume of interstitial fluid composed completely or mainly by water. In hydrogels the porous permeable solid is a water insoluble three dimensional network of natural or synthetic polymers and a fluid, having absorbed a large amount of water or biological fluids. These properties underpin several applications, especially in the biomedical area. Many hydrogels are synthetic, but some are derived from nature.
UrologyUrology (from Greek οὖρον ouron "urine" and -λογία -logia "study of"), also known as genitourinary surgery, is the branch of medicine that focuses on surgical and medical diseases of the urinary-tract system and the reproductive organs. Organs under the domain of urology include the kidneys, adrenal glands, ureters, urinary bladder, urethra, and the male reproductive organs (testes, epididymis, vas deferens, seminal vesicles, prostate, and penis). The urinary and reproductive tracts are closely linked, and disorders of one often affect the other.
Rabbit hemorrhagic diseaseRabbit hemorrhagic disease (RHD), also known as viral hemorrhagic disease (VHD), is a highly infectious and lethal form of viral hepatitis that affects European rabbits. Some viral strains also affect hares and cottontail rabbits. Mortality rates generally range from 70 to 100 percent. The disease is caused by strains of rabbit hemorrhagic disease virus (RHDV), a lagovirus in the family Caliciviridae. Rabbit hemorrhagic disease virus (RHDV) is a virus in the genus Lagovirus and the family Caliciviridae.
Sewage treatmentSewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. Sewage contains wastewater from households and businesses and possibly pre-treated industrial wastewater. There are a high number of sewage treatment processes to choose from.
Stem-cell therapyStem-cell therapy is the use of stem cells to treat or prevent a disease or condition. , the only established therapy using stem cells is hematopoietic stem cell transplantation. This usually takes the form of a bone-marrow transplantation, but the cells can also be derived from umbilical cord blood. Research is underway to develop various sources for stem cells as well as to apply stem-cell treatments for neurodegenerative diseases and conditions such as diabetes and heart disease.
