Self-actualization
Self-actualization is a term that has been used in various psychology theories, often in slightly different ways. The term was originally introduced by the organismic theorist Kurt Goldstein for the motive to realize one's full potential. Expressing one's creativity, quest for spiritual enlightenment, pursuit of knowledge, and the desire to give to society are examples of self-actualization. In Goldstein's view, it is the organism's master motive, the only real motive: "the tendency to actualize itself as fully as possible is the basic drive... the drive of self-actualization. As Abraham Maslow noted, the basic needs of humans must be met (e.g. food, shelter, warmth, security, sense of belongingness) before a person can achieve self-actualization - the need to be good, to be fully alive and to find meaning in life.

Épigénétique
Un article de Wikipédia, l'encyclopédie libre. L'épigénétique est l'ensemble des mécanismes moléculaires concernant le génome ainsi que l'expression des gènes, qui peuvent être influencés par l'environnement et l'histoire individuelle. Ces mécanismes peuvent être potentiellement transmissibles d'une génération à l'autre, sans altération des séquences nucléotidiques (ADN), et avec un caractère réversible. L'existence de phénomènes agissant sur l'expression des gènes se résume dans l'interrogation de Thomas Morgan « Si les caractères de l'individu sont déterminés par les gènes, pourquoi toutes les cellules d'un organisme ne sont-elles pas identiques ? Les différences qui existent entre chaque cellule d'un même organisme ayant le même patrimoine génétique - mis à part quelques rares mutations somatiques - montrent une expression différentielle des gènes. Des phénomènes épigénétiques ont été mis en évidence chez des eucaryotes et des procaryotes. Épigénome[modifier | modifier le code]

Concision
Description[edit] Concision may involve removing redundant or unnecessary phrases or replacing them with shorter ones. It is described in The Elements of Style by Strunk and White as follows:[1] Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts. This requires not that the writer make all his sentences short, or that he avoid all detail and treat his subjects only in outline, but that every word tell. Concision has also been described as "eliminat[ing] words that take up space without saying much An example sentence, with explanation:[2] "It is a fact that most arguments must try to convince readers, that is the audience, that the arguments are true." Example paragraph[edit] The following example is taken from:[3] The author of the poem illustrated various differences between the characters. This can be replaced with:
Control of Gene Expression
Return to The Medical Biochemistry Page © 1996–2013 themedicalbiochemistrypage.org, LLC | info @ themedicalbiochemistrypage.org The controls that act on gene expression (i.e., the ability of a gene to produce a biologically active protein) are much more complex in eukaryotes than in prokaryotes. A major difference is the presence in eukaryotes of a nuclear membrane, which prevents the simultaneous transcription and translation that occurs in prokaryotes. Whereas, in prokaryotes, control of transcriptional initiation is the major point of regulation, in eukaryotes the regulation of gene expression is controlled nearly equivalently from many different points. back to the top In bacteria, genes are clustered into operons: gene clusters that encode the proteins necessary to perform coordinated function, such as biosynthesis of a given amino acid. In bacteria, control of the rate of transcriptional initiation is the predominant site for control of gene expression. back to the top 1. 2. 3. 4. 5.
Xenoglossy
Xenoglossy (/ˈziːnɵɡlɒsi/ or /ˈzɛnɵɡlɒsi/), also written xenoglossia (/ziːnɵˈɡlɒsiə/ or /zɛnɵˈɡlɒsiə/), is the putative paranormal phenomenon in which a person is able to speak or write a language he or she could not have acquired by natural means. For example, a person who speaks Swedish fluently, but who is not a native Swedish speaker, has never studied Swedish, never been to a Swedish-speaking country, and never associated with Swedish speakers or had any other source of exposure to the Swedish language, would be said to exhibit xenoglossy. The existence of xenoglossy is not generally accepted by skeptic linguists such as Samarin (1976) and Thomason (1984, 1987, 1996). However, psychiatrist and paranormal researcher Ian Stevenson documented several cases that he considered authentic (Stevenson, 2001). The words derive from Greek ξένος (xenos), "foreigner"[1] and γλῶσσα (glōssa), "tongue" or "language".[2] In Christianity[edit] Cases subjected to scientific investigation[edit] Sharada
Archaea
The Archaea ( Archaea were initially classified as bacteria, receiving the name archaebacteria (or Kingdom Monera), but this classification is outdated.[1] Archaeal cells have unique properties separating them from the other two domains of life: Bacteria and Eukaryota. The Archaea are further divided into four recognized phyla. Classification[edit] New domain[edit] Current classification[edit] The classification of archaea, and of prokaryotes in general, is a rapidly moving and contentious field. A superphylum - TACK - has been proposed that includes the Aigarchaeota, Crenarchaeota, Korarchaeota and Thaumarchaeota.[18] This superphylum may be related to the origin of eukaryotes. Species[edit] The classification of archaea into species is also controversial. Archaea show high levels of horizontal gene transfer between lineages.
