T h e cell cycle includes interphase, mitosis, cytoplasmic division, and differentiation. Chromosome tips that shorten with each mitosis provide a mitotic clock, usually limiting the number of divisions to fifty. A s a cell grows, its surface area increases to a lesser degree than its volume, and eventually the area becomes inadequate for the requirements of the living material within the cell. W h e n a cell divides, die daughter cells have more favorable surface area-volume relationships. A stem cell divides to yield another stein cell and a progenitor cell that is partially differentiated. Cells that give rise to any differentiated cell type are totipotent, Cells with more restricted fates are pluripotent. Stem cells may be present in adult organs or migrate from the bone marrow to replace damaged cells-or both.

The futile searching for inspiration in the wrong direc tion is the greatest blunder of artistic temperaments skin care 4men wendy zoretanin 10 mg lowest price. Even though it may not always seem to interfere immediately with their artistic expression acneorg purchase zoretanin 20 mg with mastercard, this error is undoubtedly the fore most cause of the fits of melancholy acne 4 year old purchase 20 mg zoretanin otc, the moodiness and lack of balance of which so many artists suffer skin care questionnaire discount 20 mg zoretanin. And these dis turbances within cannot fail to exert a deleterious influence on their art, which as a result in many cases shows a deca dence after a short period of auspicious productivity. If artists could always aspire to inspiration in a truly supersensuous way, free from the lower attractions of the senses, it could be theirs almost continuously. True art can only be produced by one who keeps the channel for inspiration free from sensual obstructions - be it only in preparation for and during the execution of a spe cial work. There are great "artists who feel most fit for work when refraining entirely from sexual intercourse. Gruber, "The Hygienic Significance of Marriage"; in: Senator-kaminer, Health and Disease, 20. But it cannot be of any help while so little of while on an average only tenth of its full ca being used. The mind cannot fulfill its liberating mission so long as people continue to make use of what little in the diffused and untoward way they have available of in which most of them apply it. When applied exclusively to material interests, only concrete lower mind can become manifest this part of the mind which has become blinded by the density of mat its highest mode of expression. When ap ter, and intellect plied to spiritual concerns another part of the mind, ab stract Mind begins to manifest and to open the way to intui tion. In other words, one might say that materialistic-intel lectual man uses the mind, while intuitive-spiritual man uses it, is it it a Mind. In the form of physical instinct this unfailing intelligence un consciously and only partially partaken of by the mindless animal. Through tuition - through allround exercise of his mind, and by gradually developing Mind - he must learn how to acquire intuition, which might be called spiritual in; is; is a 39 is 6o stinct. Man used his mind to excite these impulses con stantly beyond their natural usefulness. Having continued this stimulation of the passions through the ages, the greater part of the race still clings to the habit of using the mind in ordinately in that detrimental way. Thus in the course of time "consciousness and memory have greatly strengthened the hold of sex on mankind. The result is that humanity is over sexed"1, and that the abuse of sex has grown excessive. But in order to be able to cross this thresh old one must first realize that "he who wants to enter into the sanctuary must die to . Even without looking for spiritual attainments the nor mal growth of intellect itself depends upon a strict limitation of sexual expression. For in individual development as well as in the evolution of the race intellectual power is a mani festation of the life force. Whatever amount of this force is trifled away in sex, is lost to the possibility of being trans formed into intellectual energy. This not to say that everybody who refrains from sex ual acts can thereby become highly intellectual. Not every born with the potential capacity out of which intel body lectual genius can be developed. Moreover, many who do not waste part of their life force in sexual activity fritter away in petty personal concerns and in endless small talk. Therefore, "if the human race is to progress in an intellec tual direction it must become. They indicate that "true progress in the individual and in society consists in a growing spiritualization and in the ever more complete mas tery of spirit over matter. The great major ity has always refused to heed the requirements for spiritual unfoldment - with the result that the very meaning of spirituality remains little understood. Some materialists even deny that it can have any meaning, because they have never been able to see or sense or in any way experience it. In the earliest stages of expression of life in form physical bodies had to be built.

It is in this way that religious theodicies have restricted not only the selfhood but the social protest capacity of their believers acne treatment home remedies zoretanin 20 mg sale. In so doing acne out- purchase zoretanin paypal, of course acne quick treatment purchase zoretanin 40 mg with visa, they have also di rectly legitimated the institutional order in question acne under jaw buy discount zoretanin 40 mg on line. As Berger has noted, "the theodicy constitutes an essentially sado-masochistic collusion, on the level of meaning, be tween oppressors and victims. A not-so-incidental by-product of this particular medical theodicy is the enlargement of medical knowledge about manipulating organs of the body which specifically func tion to define biological sex. This, of course, works to the ultimate benefit of the sadistic side of the theodicy, en abling medical research and technology to acquire a spe cialized body of scientific knowledge on the manipulation of human sexuality that probably could not be acquired by any other accepted medical procedure. At least two re 146 the Transsexual Empire searchers have admitted this, although the admissions, of course, are mixed with therapeutic qualifications. Richard Green has stated: To a considerable degree, the medical profession itself is responsible for the limited extent of knowledge which currently exists about transsexualism and sex reassignment. While the current availability of gonadal hormones and the refinement o f surgical techniques have made it possible to partly realize the fantasies and aspirations of the transsexual and have brought about an increasing demand for sex reassignment, medicine, by closing the door to these patients for study and treatment, has cast away a population from whom con siderable information about gender identity and human sexuality could have been obtained. Particularly in the United States, until very recently, sex reassignment has been nearly unobtainable. Consequently, neither pre operative screening nor postoperative evaluations were made. Certainly it offers doctors an unrivaled opportunity to study and understand the dynamics of gender as it relates to human function and self imagery. A third issue to consider is just how informed consent can be attained, especially in the face of so many unknown hazards about the experiment. First of all, a truly in formed consent would highlight, for the transsexual, the 147 Therapy as a Way of Life whole issue of sex roles and gender definitions themselves. It would reveal to him how moving from one stereotype to its opposite does not even minimally alter the social basis of sex-role conformity in this culture and how the transsexual, in undertaking surgery, is reinforcing this con formity. My survey of the literature and first-hand interviews with transsexuals and transsexual clinicians thus far have revealed that these social hazards, or even their possibility, are not explored. Furthermore, it has generally been recognized that the withholding or distortion of any relevant knowledge that bears upon the experiment constitutes a violation of in formed consent. It is questionable whether even the phy sical hazards of transsexual treatment and surgery are explained to the would-be transsexual. Finally, the issue of informed consent enters again in the context of the ethics of experimentation. Discussions on medical experimentation have focused on the question of whether a truly informed consent can ever be obtained from a "captive population. Otto Guttentag has written: It is generally agreed in our culture, experimental subjects must be volunteers. What is meant by the word is, first, that the experimental subjects who agree to volunteer are judged by society as free in the psychological sense, as experiencing themselves ultimately as centers o f autonomy, whatever the contingencies; and second, that they are free in the sociological sense, that is, not dependent upon the ex perimenter to satisfy their spiritual or physical needs. How can they be ultimately "centers of autonomy" if their motivation to choose differently is held captive by a patriarchal society, so that even what they finally do choose. Secondly, how are transsexuals free in the " sociological sense" when in- 148 the Transsexual Empire deed they do depend upon the experimenters to "satisfy" their "spiritual needs" (the conviction and fulfillment of, for example, finally becoming a woman) and "physi cal needs". Much of the litera ture on medical experimentation has focused on the various captive populations of prisoners and mental pa tients, but the most notorious example of unethical medi cal experimentation on a captive population is the Nazi concentration camps. The example of the Nazi camps has often been cited in ethical arguments that attempt to sen sationalize and disparage opposing views. In mentioning the Nazi experi ments, it is not my purpose to directly compare trans sexual surgery to what went on in the camps but rather to demonstrate that much of what did go on there can be of value in surveying the ethics of transsexualism. The specter of unethical medical experimentation loomed large after the publicity that was given to the Nazi concentration camps during World War Two. In fact, one of the first comprehensive codes of medical ethics, specifically dealing with the ethics of experimenta tion, emerged from the Nuremberg trials in the wake of the famous "Doctors Trial" or, as it is sometimes called, the "Trial of the Twenty-Three. High-aititude tests were done on prisoners to observe the point at which they stopped breathing. Inmates of the camps were subjected to freezing experiments to observe the changes that take place in a person during this kind of slow death, and also to deter mine the point of no return.
