Third Response, posted by jim f on September 09, 1998 at 17:19:07: yet, in his lifetime, he was the object of intense opposition by almost the entire biological establishment, because of his own opposition to spontaneous generation and to darwinism. Contrary to what one would gather from Henry morris, pasteur's views on evolution seem to be unknown. He *was* strongly opposed to spontaneous generation, but seems never to have expressed an opinion on evolution. Origins once posted the following from the dictionary of Scientific biography: Pasteur, oeuvres, v, 101; ii, 411. Pasteur only once used Darwin's name in print-while pointing out that the belief in microbial transformism was losing ground by 1876, "in spite of the growing favor of Darwin's system." Ibid., v,. Fourth Response, posted by mockingbird1 on September 09, 1998 at 21:59:48: PK: i've noted a bit of incredulity on your summary. Pasteur, on the part of the evolutionists.

Meyer: As far as spontanious generation and abiogenesis goes, well good science knows it can't happen. Pat: Two report different ideas. The point is that there is evidence for abiogenesis. Not enough yet (IMO) to say for sure, but it looks promising. Response to q, posted by kevin Kamberg on September 09, 1998 at 15:11:24: Q: see, good science wins out in the end. Yes it did, despite the intense opposition thesis of the darwinists! Second Response, posted by lucas on September 09, 1998 at 17:09:07: Assuming the story is entirely as you say it is, without embellishment, what has the story of a nineteenth-century biologist to do with twentieth-century scientific peer review? Response to lucas, posted by mockingbird1 on September 09, 1998 at 19:42:31: PK: How was Pasteur's work received by his peers? PK: The application of his work spoke volumes more then the assent of his peers, and more favorably! Response to mockingbird1, precisely! You get an A for paying attention.
Response to q, posted by meyer on September 09, 1998 at 15:10:13: see, good science wins out in the end. Pasteur's peers didn't help one bit. And he is also a good case for why darwinism means squat to biology. As far as spontaneous generation and abiogenesis goes, well good science knows it can't happen. Bad and misleading science says essay it's a fact, or it could happen. Response to meyer, posted by pat on September 12, 1998 at 19:42:36: meyer: see, good science wins out in the end. It is a case in point of how biased opinions like joe's and yours lose everytime. Biologists overwhelmingly accept the fact of evolution. It's like saying math means squat to engineering.
Pasteur was a strongly religious man, and ever more so as he grew older. When asked about his faith, pasteur would reply: "The more i know, the more does my faith approach that of the Breton peasant. Could I but know all, i would have the faith of a breton peasant woman."-taken from. Men of Science-men of God by henry morris. Isbn copyright (c) 1982, 1988. First Response, posted by q on September 09, 1998 at 14:46:46: see, good science wins out in the end. Scientists did not give up the idea of naturalistic origins of life, what they gave up was the idea of spontaneous generation. You know, flies sprouting from rotted meat for no reason, that sort of thing.

Posted by kevin Kamberg on September 09, 1998 at 14:38:23: louis Pasteur is one of the greatest names in the history of science and medicine, chiefly because of his establishment of the germ theory of disease and his conclusive demolition of the then prevalent evolutionary. He was a physicist and chemist in these fields. He was the first to explain the organic basis and control of fermentation, and as his research led him more and more into bacteriology, he isolated a number of disease-producing organisms and developed vaccines to combat them-notably the dread diseases of rabies, diptheria, anthrax, and. He undoubtedly made the greatest contribution of any one man to the saving of human lives, and most scientists today would say that he was the greatest biologist of all time. Yet, in his lifetime, he was the object of intense opposition by almost the entire biological establishment, because of his own opposition to spontaneous generation and to darwinism. It was only his persistence and sound experimental and analytical procedures that finally compelled most biological and medical scientists to give up their ideas of the naturalistic origin of life and their treatment of disease as based on this notion.
The heads are in close association with Sertoli* cells, and the tails project into the lumen of the seminiferous tubule. Condensed nuclei forming the heads of spermatozoa contain a single set of chromosomes. Spermatozoa are the source of testicular hyaluronidase, an enzyme that may play a role in fertilization. Sertoli cell: These are supporting cells of the testicular epithelium. Tall columnar cells extend from the basement membrane to the lumen. These cells possess ovoid nuclei with a prominent nucleolus (seen here).
Cell borders are not distinguished with light microscopy. Spermatozoa develop in intimate relation with the apical cytoplasmic processes of Sertoli cells. Basement membrane : Surrounds seminiferous tubules, and is augmented by outer layers of connective tissue. Sertoli, was an, italian histologist.

Stratified germinal epithelium, rhesus monkey, helly's fluid, iron hematoxylin and orange g stains,. The germinal epithelium of the seminiferous tubules is composed of several layers of spermatogenic cells disposed between the basement membrane of the tubule and the lumen (see plate 265 about ). Primary spermatocyte: Largest germ cell. Nuclei are large and vesicular and have condensed chromatin. Chromatin may appear as elongated threads. Maturing spermatozoa: Mature germinal cell consisting of a head and a tail.

accepted dogma that the total number of follicles and oocytes is established in human ovaries during the fetal period of life rather than forming de novo in adult ovaries, some new evidence in the field challenges this understanding. Several studies have shown that different populations of stem cells, such as germinal stem cells and small round stem cells with diameters of 2 to 4 µm, that resembled very small embryonic-like stem cells and expressed several genes related to primordial germ cells, pluripotency, and. These small stem cells were pushed into the germinal direction of development and formed primitive oocyte-like cells in vitro. Moreover, oocyte-like cells were also formed in vitro from embryonic stem cells and induced pluripotent stem cells. This indicates that postnatal oogenesis is not excluded. It is further supported by the occurrence of mesenchymal stem cells that can restore the function of sterilized ovaries and lead to the formation of new follicles and oocytes in animal models. Both oogenesis in vitro and transplantation of stem cell-derived oocytes into the ovarian niche to direct their natural maturation represent a big challenge for reproductive biomedicine in the treatment of female infertility in the future and needs to be explored and interpreted with caution, but.
Peer review can be done well or badly or somewhere in between. It depends a lot on how expert are the reviewers, how much time they pay to the work, whether they are good readers, and also, it has to be said, how open they are to someone saying something different than their predispositions. I have sixteen publications in philosophy and have had a very wide range of responses to various articles. Sometimes there is a very careful reading, sometimes the reader shows no knowledge whatsoever of the subject, and sometimes there are egregious mistakes and misreadings, as in a recent paper rejected by the australasian journal of Philosophy (was that the exact title?). When I listed the referee's mistakes, the Editor stated that I had a very good case and that he was essay very disappointed in the extremely senior, famous referee, whom he thought he could trust. A second reading by someone else was very clear, detailed and helpful, if negative and still prey to analytic prejudices that say you need not justify your 'intuitions' about substantive matters. Edited (non peer reviewed) journals can be as or more reliable as peer reviewed journals. In co-editing a special journal issue recently, i gave very careful readings, rewrote what was necessary to make it better, and was an expert on the subject, so i think that there are better and worse ways of dealing with scholarly review, although there. Sometimes editorial decisions in the humanities are dependent less on whether they agree with the article but how wide the readership is likely to be, or how much controversy the articles may engender.
