IVF in vitro fertilisation in human

In vitro fertilisation (IVF

In vitro fertilisation is a process of fertilisation where an egg is combined with sperm outside the body, in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process, removing an ovum or ova (egg or eggs) from the woman's ovaries and letting sperm fertilise them in a liquid in a laboratory. The fertilised egg (zygote) undergoes embryo culture for 2–6 days, and is then transferred to the same or another woman's uterus, with the intention of establishing a successful pregnancy.

IVF is a type of assisted reproductive technology used for infertility treatment and gestational surrogacy, in which a fertilised egg is implanted into a surrogate's uterus, and the resulting child is genetically unrelated to the surrogate. Some countries banned or otherwise regulate the availability of IVF treatment, giving rise to fertility tourism. Restrictions on availability of IVF include costs and age to carry a healthy pregnancy to term. IVF is mostly attempted if less invasive or expensive options have failed or are unlikely to work.

The first successful birth of a child after IVF treatment, Louise Brown, occurred in 1978. Louise Brown was born as a result of natural cycle IVF where no stimulation was made. The procedure took place at Dr Kershaw's Cottage Hospital (now Dr Kershaw's Hospice) in Royton, Oldham, England. Robert G. Edwards was awarded the Nobel Prize in Physiology or Medicine in 2010, the physiologist who co-developed the treatment together with Patrick Steptoe and embryologist Jean Purdy; Steptoe and Purdy were not eligible for consideration as the Nobel Prize is not awarded posthumously.

Beer production

Brewing  is the production of  beer  by steeping  a  starch  source (commonly cereal  grains, the most popular of which is  barley ) [1]  in water and  fermenting  the resulting sweet liquid with  yeast . It may be done in a  brewery  by a commercial brewer, at home by a  homebrewer , or by a variety of traditional methods such as communally by the  indigenous peoples in Brazil  when making  cauim . [2]  Brewing has taken place since around the 6th millennium BC, and archaeological evidence suggests that emerging civilizations including  ancient Egypt [3] and  Mesopotamia  brewed beer. [4]  Since the nineteenth century the  brewing industry  has been part of most western economies. The basic ingredients of beer are water and a  fermentable  starch source such as  malted barley . Most beer is fermented with a  brewer's yeast  and fl...

What is Insomnia? If you can't sleep, you may be wondering if you have insomnia. Insomnia is a complicated condition. What is the definition of insomnia? According to guidelines from a physician group,  insomnia  is difficulty falling asleep or staying asleep, even when a person has the chance to do so. People with insomnia can feel dissatisfied with their sleep and usually experience one or more of the following symptoms : fatigue, low energy, difficulty concentrating, mood disturbances, and decreased performance in work or at school. How long does insomnia last? Insomnia may be characterized based on its duration.  Acute insomnia  is brief and often happens because of life circumstances (for example, when you can't fall asleep the night before an exam, or after receiving stressful or bad news). Many people may have experienced this type of passing sleep disruption, and it tends to resolve without any treatment. Chronic insomnia  is d...

Ethanol fermentation

Ethanol fermentation Read in another language Watch this page Edit In ethanol fermentation, (1) one glucose molecule breaks down into two pyruvates. The energy from this exothermic reaction is used to bind the inorganic phosphates to ADP and convert NAD+ to NADH. (2) The two pyruvates are then broken down into two acetaldehydes and give off two CO2 as a by-product. (3) The two acetaldehydes are then converted to two ethanol by using the H- ions from NADH, converting NADH back intoNAD+.                     Ethanol fermentation , also called alcoholic fermentation , is a   biological process   which converts   sugars   such as glucose ,   fructose , and   sucrose   into cellular energy , producing   ethanol   and carbon dioxide   as by-products. Because yeasts   perform this conversion in the absence of   oxygen , alcoholic fermentation   is conside...
