Lulu And Nana
The He Jiankui affair is a scientific and Bioethics, bioethical controversy concerning the use of genome editing following its first use on humans by Chinese scientist He Jiankui, who edited the genomes of human embryos in 2018. He became widely known on 26 November 2018 after he announced that he had created the first human genetically edited babies. He was listed in the ''Time (magazine), Time'''s Time 100, 100 most influential people of 2019. The affair led to legal and ethical controversies, resulting in the indictment of He and two of his collaborators, Zhang Renli and Qin Jinzhou. He eventually received widespread condemnation from all over the world. He Jiankui, working at the Southern University of Science and Technology (SUSTech) in Shenzhen, China, started a project to help people with HIV and pregnancy, HIV-related fertility problems, specifically involving HIV-positive people, HIV-positive fathers and HIV-negative mothers. The subjects were offered standard in vitro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

He Jiankui (; ; born 1984) is a Chinese biophysicist who was an associate professor in the Department of Biology of the Southern University of Science and Technology (SUSTech) in Shenzhen, China. Earning his Ph.D. from Rice University in Texas on protein evolution, including that of CRISPR, He learned gene-editing techniques ( CRISPR/Cas9) as a postdoctoral researcher at Stanford University in California. He Jiankui became widely known in November 2018 after he announced that he had created the first human genetically edited babies, twin girls who were born in mid-October 2018 and known by their pseudonyms, Lulu and Nana. The announcement was initially praised in the press as a major scientific advancement. But following scrutiny on how the experiment was executed, He received widespread condemnation. He's research activities were suspended by the Chinese authorities on 29 November 2018, and he was fired by SUSTech on 21 January 2019. On 30 December 2019, Chinese court se ...

CCR5-Δ32
C-C chemokine receptor type 5, also known as CCR5 or CD195, is a protein on the surface of white blood cells that is involved in the immune system as it acts as a receptor for chemokines. In humans, the ''CCR5'' gene that encodes the CCR5 protein is located on the short (p) arm at position 21 on chromosome 3. Certain populations have inherited the ''Delta 32'' mutation, resulting in the genetic deletion of a portion of the CCR5 gene. Homozygous carriers of this mutation are resistant to M-tropic strains of HIV-1 infection. Function The CCR5 protein belongs to the beta chemokine receptors family of integral membrane proteins. It is a G protein–coupled receptor which functions as a chemokine receptor in the CC chemokine group. CCR5's cognate ligands include CCL3, CCL4 (also known as MIP 1''α'' and 1''β'', respectively), and CCL3L1. CCR5 furthermore interacts with CCL5 (a chemotactic cytokine protein also known as RANTES). CCR5 is predominantly expressed on T cells ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genome Editing
Genome editing, or genome engineering, or gene editing, is a type of genetic engineering in which DNA is inserted, deleted, modified or replaced in the genome of a living organism. Unlike early genetic engineering techniques that randomly inserts genetic material into a host genome, genome editing targets the insertions to site-specific locations. The basic mechanism involved in genetic manipulations through programmable nucleases is the recognition of target genomic loci and binding of effector DNA-binding domain (DBD), double-strand breaks (DSBs) in target DNA by the restriction endonucleases ( FokI and Cas), and the repair of DSBs through homology-directed recombination (HDR) or non-homologous end joining (NHEJ). History Genome editing was pioneered in the 1990s, before the advent of the common current nuclease-based gene editing platforms, however, its use was limited by low efficiencies of editing. Genome editing with engineered nucleases, i.e. all three major classes of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Informed Consent
Informed consent is a principle in medical ethics and medical law, that a patient must have sufficient information and understanding before making decisions about their medical care. Pertinent information may include risks and benefits of treatments, alternative treatments, the patient's role in treatment, and their right to refuse treatment. In most systems, healthcare providers have a legal and ethical responsibility to ensure that a patient's consent is informed. This principle applies more broadly than healthcare intervention, for example to conduct research and to disclosing a person's medical information. Definitions of informed consent vary, and the standard required is generally determined by the state. Informed consent requires a clear appreciation and understanding of the facts, implications, and consequences of an action. To give informed consent, the individual concerned must have adequate reasoning faculties and possess all relevant facts. Impairments to reasoning an ...

In Vitro Fertilisation
In vitro fertilisation (IVF) is a process of fertilisation where an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating an individual's ovulatory process, removing an ovum or ova (egg or eggs) from their ovaries and letting sperm fertilise them in a culture medium in a laboratory. After the fertilised egg (zygote) undergoes embryo culture for 2–6 days, it is transferred by catheter into the uterus, with the intention of establishing a successful pregnancy. IVF is a type of assisted reproductive technology used for infertility treatment, gestational surrogacy, and, in combination with pre-implantation genetic testing, avoiding transmission of genetic conditions. A fertilised egg from a donor may implant into a surrogate's uterus, and the resulting child is genetically unrelated to the surrogate. Some countries have banned or otherwise regulate the availability of IVF treatment, giving rise to fertility tourism. Restrictions ...

Chinese Yuan
The renminbi (; symbol: ¥; ISO code: CNY; abbreviation: RMB) is the official currency of the People's Republic of China and one of the world's most traded currencies, ranking as the fifth most traded currency in the world as of April 2022. The yuan ( or ) is the basic unit of the renminbi, but the word is also used to refer to the Chinese currency generally, especially in international contexts. One yuan is divided into 10 jiao (), and the jiao is further subdivided into 10 fen (). The renminbi is issued by the People's Bank of China, the monetary authority of China. Valuation Until 2005, the value of the renminbi was pegged to the US dollar. As China pursued its transition from central planning to a market economy and increased its participation in foreign trade, the renminbi was devalued to increase the competitiveness of Chinese industry. It has previously been claimed that the renminbi's official exchange rate was undervalued by as much as 37.5% against its pur ...
