Growth hormones. 1. Polymorphism (minireview).
Pituitary growth hormone (GH) is not a single molecular species, but a whole set of similar molecules, the individual specific characteristics of which constitute the polymorphism of this hormone. The present paper deals mainly with various forms of human GH, called "variants", and touches on this polymorphism in other species as well. The 22 K variant (MW = 22,000 daltons) is the predominant f...
متن کاملArithmetic without Fear *Abridged.
Now why should such things be ? How can we make the rough places plain and the crooked straight, so that all children may enter into their rightful heritage, that fairyland which the realm of number was to Lewis Carroll or A. A. Milne ? The extent of the Arithmetic phobia is not so widespread as it is usually supposed to be. I have repeatedly found that the majority of small children really do ...
متن کاملAbridged Petri Nets
A new graphical framework, Abridged Petri Nets (APNs) is introduced for bottom-up modeling of complex stochastic systems. APNs are similar to Stochastic Petri Nets (SPNs) in as much as they both rely on component-based representation of system state space, in contrast to Markov chains that explicitly model the states of an entire system. In both frameworks, so-called tokens (denoted as small ci...
متن کاملLogical Induction (Abridged)∗
We present a computable algorithm that assigns probabilities to every logical statement in a given formal language, and refines those probabilities over time. For instance, if the language is Peano arithmetic, it assigns probabilities to all arithmetical statements, including claims about the twin prime conjecture, the outputs of long-running computations, and its own probabilities. We show tha...
متن کاملBushbaby growth hormone is much more similar to nonprimate growth hormones than to rhesus monkey and human growth hormones.
Unlike other mammals, Old World primates have five growth hormone-like genes that are highly divergent at the amino acid level from the single growth hormone genes found in nonprimates. Additionally, there is a change in the interaction of growth hormone with its receptor in humans such that human growth hormone functions in nonprimates, whereas nonprimate growth hormone is ineffective in human...
