Do not lose time worrying excessively about what happened in the past, nor about what could happen in the future. They learn from the past and plan for the future, but live in the present intensely. Fully trust in their capacity to solve problems, not hesitating after failures and difficulties. They ask others for help when they need it. Consider themselves equal in dignity to others, rather than inferior or superior, while accepting differences in certain talents, personal prestige or financial standing. Understand how they are an interesting and valuable person for others, at least for those with whom they have a friendship. Resist manipulation, collaborate with others only if it seems appropriate and convenient. Admit and accept different internal feelings and drives, either positive or negative, revealing those drives to others only when they choose. Are able to enjoy a great variety of activities. Are sensitive to feelings and needs of others; respect generally accepted social rules, and claim no right or desire to prosper at others expense. Can work toward finding solutions and voice discontent without belittling themselves or others when challenges arise. Secure vs. defensive
A person can have high self-esteem and hold it confidently where they do not need reassurance from others to maintain their positive self-view, whereas others with defensive high self-esteem may still report positive self-evaluations on the Rosenberg Scale, as all high self-esteem individuals do; however, their positive self-views are fragile and vulnerable to criticism.

Ciclosporin is a cyclic peptide of 11 amino acids; it contains a single D-amino acid, which is rarely encountered in nature. Unlike most peptides, ciclosporin is not synthesized by ribosomes.Ciclosporin is highly metabolized in humans and animals after ingestion. The metabolites, which include cyclosporin B, C, D, E, H, and L, have less than 10% of ciclosporins immunosuppressant activity and are associated with higher kidney toxicity. Individual ciclosporin metabolites have been isolated and characterized but do not appear to be extensively studied. Biosynthesis
Cyclosporin is synthesized by a nonribosomal peptide synthetase, cyclosporin synthetase. The enzyme contains an adenylation domain, a thiolation domain, a condensation domain, and an N-methyltransferase domain. The adenylation domain is responsible for substrate recognition and activation, whereas the thiolation domain covalently binds the adenylated amino acids to phosphopantetheine, and the condensation domain elongates the peptide chain. Cyclosporin synthetase substrates include L-valine, L-leucine, L-alanine, glycine, 2-aminobutyric acid, 4-methylthreonine, and D-alanine, which is the starting amino acid in the biosynthetic process. With the adenylation domain, cyclosporin synthetase generates the acyl-adenylated amino acids, then covalently binds the amino acid to phosphopantetheine through a thioester linkage. Some of the amino acid substrates become N-methylated by S-adenosyl methionine. The cyclization step releases cyclosporin from the enzyme. Amino acids such as D-Ala and butenyl-methyl-L-threonine (Bmt) indicate cyclosporin synthetase requires the action of other enzymes. The racemization of L-Ala to D-Ala by alanine racemase is pyridoxal phosphate-dependent.
