Dilationand curettage (D&C) refers to the dilation (widening/opening) of the cervix and surgical removal of part of the lining of the uterus and/or contents of the uterus by scraping and scooping (curettage). It is a therapeutic gynecological procedure as well as the most often used method of first trimester miscarriage or abortion.
Neurosurgery, or neurological surgery, is the medical specialty concerned with the prevention, diagnosis, surgical treatment, and rehabilitation of disorders which affect any portion of the nervous system including the brain, spinal cord, peripheral nerves, and extra-cranial cerebrovascular system.
A space elevator is a proposed type of planet-to-space transportation system. The main component would be a cable anchored to the surface and extending into space. The design would permit vehicles to travel along the cable from a planetary surface, such as the Earth's, directly into space or orbit, without the use of large rockets. An Earth-based space elevator would consist of a cable with one end attached to the surface near the equator and the other end in space beyond geostationary orbit. The competing forces of gravity, which is stronger at the lower end, and the outward/upward centrifugal force, which is stronger at the upper end, would result in the cable being held up, under tension, and stationary over a single position on Earth. With the tether deployed, climbers could repeatedly climb the tether to space by mechanical means, releasing their cargo to orbit. Climbers could also descend the tether to return cargo to the surface from orbit.
Lift or LIFT may refer to:
Eye surgery, also known as ocular surgery, is surgery performed on the eye or its adnexa, typically by an ophthalmologist. The eye is a very fragile organ, and requires extreme care before, during, and after a surgical procedure to minimise or prevent further damage. An expert eye surgeon is responsible for selecting the appropriate surgical procedure for the patient, and for taking the necessary safety precautions. Mentions of eye surgery can be found in several ancient texts dating back as early as 1800 BC, with cataract treatment starting in the fifth century BC. Today it continues to be a widely practiced type of surgery, having developed various techniques for treating eye problems.
The Fenelon Place Elevator is a 3 ft narrow gauge funicular railway located in Dubuque, Iowa. Also known as the Fourth Street Elevator, it is claimed to be the shortest and steepest railroad in the world. It was individually listed in the National Register of Historic Places in 1978. It was included as a contributing property in the Cathedral Historic District in 1985, and in the Fenelon Place Residential Historic District in 2015.
An elevator pitch, elevator speech, or elevator statement is a short description of an idea, product or company that explains the concept in a way such that any listener can understand it in a short period of time. This description typically explains who the thing is for, what it does, why it is needed, and how it will get done. Finally, when explaining an individual person, the description generally explains one's skills and goals, and why they would be a productive and beneficial person to have on a team or within a company or project. An elevator pitch does not have to include all of these components, but it usually does at least explain what the idea, product, company, or person is and their value.
A chylothorax is a type of pleural effusion. It results from lymph formed in the digestive system called chyle accumulating in the pleural cavity due to either disruption or obstruction of the thoracic duct.
Geisinger Medical Center is a hospital in Danville, Pennsylvania, serving as the primary hospital for the Danville-based Geisinger Health System, a primary chain of hospitals and clinics which includes the Danville medical center across northeastern and central Pennsylvania.
A retractor is a surgical instrument used to separate the edges of a surgical incision or wound, or to hold back underlying organs and tissues so that body parts under the incision may be accessed. The general term retractor usually describes a simple handheld steel tool possessing a curved, hooked, or angled blade and fitted with a comfortable handle, that when in place maintains the desired position of a given region of tissue. These simple retractors may be handheld, clamped in place, or suspended at the end of a robotic arm. Retractors can also be self-retaining and not need to be held once inserted by having two or more opposing blades or hooks which are separated via spring, ratchet, worm gear or other method. The term retractor is also used to describe distinct, hand-cranked devices such as rib spreaders with which surgeons may forcefully drive tissues apart to obtain exposure. For specialized situations such as spinal surgery, retractors have been fitted both with suction and with fiberoptic lights to keep a surgical wound dry and illuminated.
Butabarbital is a prescription barbiturate sleep aid. Butabarbital has a particularly fast onset of effects and short duration of action compared to other barbiturates, which makes it useful for certain applications such as treating severe insomnia and relieving anxiety before surgical procedures; however it is also relatively dangerous particularly when combined with alcohol, and so is now rarely used, although it is still prescribed in some Eastern European and South American countries. Its intermediate duration of action gives butabarbital an abuse potential slightly lower than secobarbital. Butabarbital can be hydrolyzed to Valnoctamide.
Zagrepčanka is a high-rise office building located in Zagreb, Croatia. The address is Savska 41, on the Savska Road and Vukovar Avenue intersection.
Intuitive Surgical Inc. is an American corporation that develops, manufactures and markets robotic products designed to improve clinical outcomes of patients through minimally invasive surgery, most notably with the da Vinci Surgical System.

As of September 30, 2017, there was an installed base of 4,271 units worldwide – 2,770 in the United States, 719 in Europe, 561 in Asia, and 221 in the rest of the world.
Dental instruments are tools that dental professionals use to provide dental treatment. They include tools to examine, manipulate, treat, restore and remove teeth and surrounding oral structures.
Hypertropia is a condition of misalignment of the eyes (strabismus), whereby the visual axis of one eye is higher than the fellow fixating eye. Hypotropia is the similar condition, focus being on the eye with the visual axis lower than the fellow fixating eye. Dissociated Vertical Deviation is a special type of hypertropia leading to slow upward drift of one or rarely both eyes, usually when the patient is inattentive.
Polycystic liver disease (PLD) usually describes the presence of multiple cysts scattered throughout normal liver tissue. PLD is commonly seen in association with autosomal-dominant polycystic kidney disease, with a prevalence of 1 in 400 to 1000, and accounts for 8–10% of all cases of end stage renal disease. The much rarer autosomal-dominant polycystic liver disease will progress without any kidney involvement.
The Puestow procedure is a surgical technique used in the treatment of chronic pancreatitis. It involves a side-to-side anastomosis of the pancreatic duct and the jejunum.
A dumbwaiter is a small freight elevator or lift intended to carry objects rather than people. Dumbwaiters found within modern structures, including both commercial, public and private buildings, are often connected between multiple floors. When installed in restaurants, schools, hospitals, retirement homes or in private homes, the lifts generally terminate in a kitchen.
An elevator or lift is a type of vertical transportation that moves people or goods between floors of a building, vessel, or other structure. Elevators are typically powered by electric motors that either drive traction cables and counterweight systems like a hoist, or pump hydraulic fluid to raise a cylindrical piston like a jack.
An inclined elevator or inclined lift is a form of a cable railway system for steep gradient.
