Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding valuable service in a wide range of useful activities. It comprises five classes of awards across both civil and military divisions, the most senior two of which make the recipient either a Orders, decorations, and medals of the United Kingdom#Modern honours, knight if male or a dame (title), dame if female. There is also the related British Empire Medal, whose recipients are affiliated with the order, but are not members of it. The order was established on 4 June 1917 by King George V, who created the order to recognise 'such persons, male or female, as may have rendered or shall hereafter render important services to Our Empire'. Equal recognition was to be given for services rendered in the UK and overseas. Today, the majority of recipients are UK citizens, though a number of Commonwealth realms outside the UK continue to make appointments to the order. Honorary awards may be made to cit ...

Wolfson College, Cambridge
Wolfson College () is a constituent college of the University of Cambridge in Cambridge, England. The majority of students at the college are postgraduates. The college also admits "mature" undergraduates (aged 21 and above), with around 15% of students studying undergraduate degree courses at the university. The college was founded in 1965 as "University College", but was refounded as Wolfson College in 1973 in recognition of a benefaction of the Wolfson Foundation. Wolfson is located to the south-west of Cambridge city centre. As one of the more modern colleges in Cambridge, Wolfson does not follow all of the traditions of some of the university's older colleges. For example, since the college's founding there has been no " High Table" reserved for Fellows at Formal Hall dinners; students and Fellows mix and dine together, and the tradition of wearing academic gowns to such occasions is encouraged but is not compulsory. Both Fellows and students at the college have acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blood–brain Barrier
The blood–brain barrier (BBB) is a highly selective semipermeable membrane, semipermeable border of endothelium, endothelial cells that regulates the transfer of solutes and chemicals between the circulatory system and the central nervous system, thus protecting the brain from harmful or unwanted substances in the blood. The blood–brain barrier is formed by endothelial cells of the Capillary, capillary wall, astrocyte end-feet ensheathing the capillary, and pericytes embedded in the capillary basement membrane. This system allows the passage of some small molecules by passive transport, passive diffusion, as well as the selective and active transport of various nutrients, ions, organic anions, and macromolecules such as glucose and amino acids that are crucial to neural function. The blood–brain barrier restricts the passage of pathogens, the diffusion of solutes in the blood, and Molecular mass, large or Hydrophile, hydrophilic molecules into the cerebrospinal fluid, while a ...

Nanoparticle
A nanoparticle or ultrafine particle is a particle of matter 1 to 100 nanometres (nm) in diameter. The term is sometimes used for larger particles, up to 500 nm, or fibers and tubes that are less than 100 nm in only two directions. At the lowest range, metal particles smaller than 1 nm are usually called atom clusters instead. Nanoparticles are distinguished from microparticles (1-1000 μm), "fine particles" (sized between 100 and 2500 nm), and "coarse particles" (ranging from 2500 to 10,000 nm), because their smaller size drives very different physical or chemical properties, like colloidal properties and ultrafast optical effects or electric properties. Being more subject to the Brownian motion, they usually do not sediment, like colloid, colloidal particles that conversely are usually understood to range from 1 to 1000 nm. Being much smaller than the wavelengths of visible light (400-700 nm), nanoparticles cannot be seen with ordinary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theranostics
Theranostics, also known as theragnostics, is a technique commonly used in Personalized medicine, personalised medicine. For example in nuclear medicine, one Radiopharmacology, radioactive drug is used to identify (Diagnosis, diagnose) and a second radioactive drug is used to treat (therapy) Cancerous tumor, cancerous tumors. In other words, theranostics combines radionuclide imaging and radiation therapy which targets specific Biological pathway, biological pathways. Technologies used for theranostic imaging include radiotracers, contrast agents, positron emission tomography, and magnetic resonance imaging. It has been used to treat thyroid cancer and Neuroblastoma, neuroblastomas. The term "theranostic" is a portmanteau of two words, ''thera''peutic and diag''nostic'', thus referring to a combination of diagnosis and treatment that also allows for continuing medical assessment of a patient. The first known use of the term is attributed to John Funkhouser, a consultant for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SiRNA
Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of double-stranded non-coding RNA molecules, typically 20–24 base pairs in length, similar to microRNA (miRNA), and operating within the RNA interference (RNAi) pathway. It interferes with the expression of specific genes with complementary nucleotide sequences by degrading messenger RNA (mRNA) after transcription, preventing translation.

Productive Nanosystems
In 2007, productive nanosystems were defined as functional nanoscale systems that make atomically-specified structures and devices under programmatic control, i.e., performing atomically precise manufacturing. As of 2015, such devices were only hypothetical, and productive nanosystems represented a more advanced approach among several to perform Atomically Precise Manufacturing. A workshop on Integrated Nanosystems for Atomically Precise Manufacturing was held by the Department of Energy in 2015. Present-day technologies are limited in various ways. Large atomically precise structures (that is, virtually defect-free) do not exist. Complex 3D nanoscale structures exist in the form of folded linear molecules such as DNA origami and proteins. As of 2018, it was also possible to build very small atomically precise structures using scanning probe microscopy to construct molecules such as FeCO and Triangulene, or to perform hydrogen depassivation lithography. But it is not yet po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desert Island Discs
''Desert Island Discs'' is a radio programme broadcast on BBC Radio 4. It was first broadcast on the BBC Forces Programme on 29 January 1942. Each week a guest, called a " castaway" during the programme, is asked to choose eight audio recordings (usually, but not always, music), a book and a luxury item that they would like to take if they were to be cast away on a desert island, whilst discussing their life and the reasons for their choices. It was devised and originally presented by Roy Plomley. Since 2018, the programme has been presented by Lauren Laverne. More than 3,400 episodes have been recorded, with some guests having appeared more than once and some episodes featuring more than one guest. An example of a guest who falls into both categories is Bob Monkhouse, who appeared with his co-writer Denis Goodwin on 12 December 1955 and in his own right on 20 December 1998. When ''Desert Island Discs'' marked its 75th year in 2017, ''The Guardian'' called the show a radio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
