Jack Lippes helped begin the increase of IUD use in the United States in the late 1950s. In this time, thermoplastics, which can bend for insertion and retain their original shape, became the material used for first-generation IUDs. Lippes also devised the addition of the monofilament nylon string, which facilitates IUD removal.
In 1964, Ortho bought rights to and marketed the Gynekoil (Margulies Coil) and Lippes Loop inert plastic IUDs in the United States until the mid-1970s and 1985, respectively. In 1968, Ortho introduced RhoGAM Rho(D) immune globulin , the first medication developed to prevent Rh hemolytic disease of the newborn .
A copper intrauterine device (IUD), also known as an intrauterine coil or copper coil or non-hormonal IUD, is a type of intrauterine device which contains copper. [3] It is used for birth control and emergency contraception within five days of unprotected sex . [ 3 ]
The size of the loop determines the volume of liquid an inoculation loop can transfer. An early report of the use of an inoculation loop as an analytical tool was by O'Sullivan et al. [3] in a 1960 published protocol developed to improve methods for culturing urine samples. A 3mm diameter loop was used to deliver a consistent volume of urine ...
Loop-mediated isothermal amplification (LAMP) primers [1] Loop-mediated isothermal amplification (LAMP) product [1]. In LAMP, the target sequence is amplified at a constant temperature of 60–65 °C (140–149 °F) using either two or three sets of primers and a polymerase like Bst Klenow fragment with high strand displacement activity in addition to a replication activity.
A rudimentary form of "dry" enema is the use of a non-medicated glycerin suppository. [1] However, due to the relative hardness of the suppository – necessary for its insertion into the human body – before glycerin can act, it must be melted by the heat of the body, and hence it does not take effect for up to an hour.
How to make non-Newtonian liquid: 2.5 cups of corn starch. 1 cup of water. 1 tablespoons of paint. After all ingredients are in a medium-sized mixing bowl, mix until well incorporated.
Alexander Wood's main contribution was the all-glass syringe in 1851, which allowed the user to estimate dosage based on the levels of liquid observed through the glass. [12] Wood used hypodermic needles and syringes primarily for the application of localized, subcutaneous injection (localized anesthesia) and therefore was not as interested in ...
