Menstrual Cup
A menstrual cup is a feminine hygiene, menstrual hygiene device which is inserted into the vagina during menstruation. Its purpose is to collect menstrual fluid (blood from the uterine lining mixed with other fluids)Menstrual cupsare made of elastomers (silicone rubbers, latex rubbers, or thermoplastic rubbers). A properly fitting menstrual cup seals against the vaginal walls, so tilting and handstand, inverting the body will not cause it to leak. It is impermeable and collects menstrual fluid, unlike tampons and menstrual pads, which absorb it.Elizabeth Gunther Stewart, Paula Spencer: ''The V Book: A Doctor's Guide to Complete Vulvovaginal Health'', Bantam Books, 2002, Seiten 96 und 97, . Menstrual cups come in two types. The older type is bell-shaped, often with a stem, and has walls more than 2mm thick. The second type has a springy rim, and attached to the rim, a bowl with thin, flexible walls. Bell-shaped cups sit over the cervix, like cervical caps, but they are generally ...

Swimming
Swimming is the self-propulsion of a person through water, such as saltwater or freshwater environments, usually for recreation, sport, exercise, or survival. Swimmers achieve locomotion by coordinating limb and body movements to achieve hydrodynamic thrust that results in directional motion. Newborns can instinctively hold their breath underwater and exhibit rudimentary swimming movements as part of a survival reflex. Swimming requires endurance, skill and efficient techniques to maximize speed and minimize energy consumption. Swimming is a popular activity and competitive sport where certain techniques are deployed to move through water. It offers numerous health benefits, such as strengthened circulatory system, cardiovascular health, muscle strength, and increased flexibility. It is suitable for people of all ages and fitness levels. Swimming is consistently among the top public recreational activities, and in some countries, swimming lessons are a compulsory part of the edu ...

Loughborough University
Loughborough University (abbreviated as ''Lough'' or ''Lboro'' for Post-nominal letters, post-nominals) is a public university, public research university in the market town of Loughborough, Leicestershire, England. It has been a university since 1966, but it dates back to 1909, when Loughborough Technical Institute was founded. In March 2013, the university announced it had bought the former broadcast centre at the Queen Elizabeth Olympic Park as a second campus. The annual income of the institution for 2023–24 was £363.2 million, of which £47.8 million was from research grants and contracts, with an expenditure of £251.6 million. In 2024, Loughborough Rankings of universities in the United Kingdom, ranked ninth nationally for undergraduate education. History The university traces its roots back to 1909, when the Loughborough Technical Institute was founded in the town centre. There followed a period of rapid expansion led by principal Herbert Schofield ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Gutta-percha
Gutta-percha is a tree of the genus ''Palaquium'' in the family Sapotaceae, which is primarily used to create a high-quality latex of the same name. The material is rigid, naturally biologically Chemically inert, inert, resilient, electrically nonconductor, nonconductive, and thermoplastic, most commonly sourced from ''Palaquium gutta''; it is a polymer of isoprene which forms a rubber-like elastomer. The word "gutta-percha" comes from the plant's name in Malay language, Malay: translates as 'sticky gum' and () is the name of a less-sought-after gutta tree. The western term therefore is likely a derivative amalgamation of the original native names. Description ''Palaquium gutta'' trees are tall and up to in trunk diameter. The leaves are evergreen, alternate or spirally arranged, simple, entire, long, glossy green above, and often yellow or glaucous below. The flowers are produced in small clusters along the stems, each flower with a white corolla (flower), corolla with f ...

India-rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the Pará rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". Manufacturers refine this latex into the rubber that is ready for commercial processing. Natural rubber is used extensively in many applications and products, either alone or in combination with other materials. In most of its useful forms, it has a large stretch ratio and high resilience and also is buoyant and water-proof. Industrial demand for rubber-like materials began to outstrip natural rubbe ...

Os Uteri
The cervical canal is the spindle-shaped, flattened canal of the cervix which connects the vagina to the main cavity of the uterus in most mammals. Anatomy The cervical canal communicates with the uterine cavity via the internal orifice of the uterus (or internal os) and with the vagina via the external orifice of the uterus (ostium of uterus or external os). The internal orifice of the uterus is an interior narrowing of the uterine cavity. It corresponds to a slight constriction known as the ''isthmus'' that can be seen on the surface of the uterus about midway between the apex and base. The external orifice of the uterus is a small, depressed, somewhat circular opening on the rounded extremity of the cervix, opening to the vagina. Through this aperture, the cervical cavity communicates with that of the vagina. The external orifice is bounded by two lips, an anterior and a posterior. The anterior is shorter and thicker, though it projects lower than the posterior because of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
MRI Imaging
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from computed tomography (CT) and positron emission tomography (PET) scans. MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy. MRI is widely used in hospitals and clinics for medical diagnosis, staging and follow-up of disease. Compared to CT, MRI provides better contrast in images of soft tissues, e.g. in the brain or abdomen. However, it may be perceived as less comfortable by patients, due to the usually longer and louder measurements with the subject in a long, confining tube, although "open" MR ...

Toxic Shock Syndrome
Toxic shock syndrome (TSS) is a condition caused by Exotoxin, bacterial toxins. Symptoms may include fever, rash, skin peeling, and low blood pressure. There may also be symptoms related to the specific underlying infection such as mastitis, osteomyelitis, necrotising fasciitis, or pneumonia. TSS is typically caused by bacteria of the ''Streptococcus pyogenes'' or ''Staphylococcus aureus'' type, though others may also be involved. Streptococcal toxic shock syndrome is sometimes referred to as toxic-shock-like syndrome (TSLS). The underlying mechanism involves the production of superantigens during an invasive streptococcus infection or a localized staphylococcus infection. Risk factors for the staphylococcal type include the use of very absorbent tampons, skin lesions in young children characterized by fever, low blood pressure, rash, vomiting and/or diarrhea, and multiorgan failure. Diagnosis is typically based on symptoms. Treatment includes intravenous fluids, antibiotic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
