The first radical hysterectomy operation was described by John G. Clark, resident gynecologist under Howard Kelly at the Johns Hopkins Hospital in 1895. [2] [3] In 1898, Ernst Wertheim, a Viennese physician, developed the radical total hysterectomy with removal of the pelvic lymph nodes and the parametrium. In 1905, he reported the outcomes of ...
Hysterectomy is the surgical removal of the uterus and cervix. Supracervical hysterectomy refers to removal of the uterus while the cervix is spared. These procedures may also involve removal of the ovaries (oophorectomy), fallopian tubes (salpingectomy), and other surrounding structures. The term “partial” or “total” hysterectomy are ...
An oil diffusion pump is used to achieve higher vacuum (lower pressure) than is possible by use of positive displacement pumps alone. Although its use has been mainly associated within the high-vacuum range, down to 1 × 10 −9 mbar (1 × 10 −7 Pa), diffusion pumps today can produce pressures approaching 1 × 10 −10 mbar (1 × 10 −8 Pa) when properly used with modern fluids and accessories.
The two main types of molecular pumps are the diffusion pump and the turbomolecular pump. Both types of pumps blow out gas molecules that diffuse into the pump by imparting momentum to the gas molecules. Diffusion pumps blow out gas molecules with jets of an oil or mercury vapor, while turbomolecular pumps use high speed fans to push the gas.
The formal name of this operation is radical vaginal trachelectomy (RVT) and also known as the Dargent operation and radical trachelectomy. [citation needed]The word radical is used as, in addition to the cervix (like in radical hysterectomies), the parametria (tissue adjacent to the cervix) and vaginal cuff (the end of the vagina close to the cervix) are also excised as a part of the ...
For example, some people had simple hysterectomy (a procedure that removes a uterus) and then discovered cervical cancer. At this point, upper vaginectomy - along with other suggested procedures such as lymphadenectomy (a procedure that removes lymph nodes) - may be suggested to people who would prefer to keep ovarian function intact.

But if you have a specific need for predictable income in 2025, then I'm going to tell you that it may be time to cash out some of your stocks and pump more of your money into a savings account.
An efflux pump is an active transporter in cells that moves out unwanted material. Efflux pumps are an important component in bacteria in their ability to remove antibiotics. [ 1 ] The efflux could also be the movement of heavy metals, organic pollutants, plant-produced compounds, quorum sensing signals, bacterial metabolites and ...
