You noted that the paper used “clinical signs” of HIV as a classification of HIV infection. What the paper actually used was PCR positivity plus signs of HIV. So I asked for you to explain how someone can be PCR positive for a virus and not be infected with the virus.
To any lurkers who might still think these flagrant truth-denialists like "true"skeptic and Roger_Mexico are being at all intellectually honest, fair, and rational, I urge you to compare their incredibly credulous and disingenuous rhetorical ploys with those of the so-called creation “scientists”. Exchange the technical terms and such between them, and they’re virtually identical!
Creationists and denialists both rely entirely on haughty, complex, and deceptive pseudo-science, which can often easily fool non-scientists and non-specialists into falsely believing that their allegedly “scientific” views have some merit and should be considered as rough scientific equals with the mainstream scientific position.
Creationists and denialists are both driven by personal, irrational, anti-science agendas, although of course they always deny this.
Creationists and denialists both rely exclusively on long-outdated and/or completely debunked claims or research, and always utterly refuse to admit that those have been debunked. Instead, they bring up cites and quotations from the obsolete and long-debunked claims/research that favor their anti-science agendas over and over and over again as if they represent something new and credible that hasn’t already been thoroughly debunked (usually many times).
Creationists and denialists both claim that mainstream science is dishonest, mindlessly monolithic, and is deliberately suppressing the “proof” of the “truth” of their bogus and anti-scientific assertions.
Creationists and denialists refuse to debate fairly and honestly. They don’t reply honestly and rationally to the arguments and facts that devastate their assertions, but instead evade them by: deliberately misrepresenting what was said; by pumping up trivialities all out of proportion; by quoting statements out of context; by citing assertions made by people outside of the appropriate field of expertise; by comparing themselves with Galileo and such, and, of course, by lying outright, among other similarly fraudulent rhetorical tactics.
If you think these denialists are sound and honest scientists, then you’ll probably think creationists are, too, and there’s probably nothing any of us can say that will change your minds.
okay.
I Have to admit that I got a little tired of the technical hair-splitting around the middle of page 3.
so, in order to cut to the chase, I offer the following observations/challenges.
Trueskeptic:
If HIV doesn’t cause AIDS, what does?
If HIV diesn’t cause AIDS, would you be willing to have yourself innoculated with live HIV virus?
If, as has been pointed out, there are many people who test positive for HIV antibodies, yet do not present symptoms of aids, and there are people who test negative for HIV antibodies, yet present AIDS-like symptoms, does this mean that cigarette smoking doesn’t cause cancer, inasmuch as there are many smokers who do not develop cancer, and there are many non-smokers who do?
How many times are you denialists going to foist such blatant falsehoods upon us?
From:KOCH’S POSTULATES FULFILLED:
Your “standards” are NOT “more rigorous”! Your “standards” simply consist of ignoring all sound, credible research and data and instead obsessing on obsolete, debunked, crackpot pseudo-science. This has always disqualified you from being taken seriously here, but it sure hasn’t kept you from continuing to deny the truth loudly and desperately.

Edwino, here is the quote again from the paper:
"Definitions
HIV-infected children were those who were seropositive by ELISA and polymerase chain reaction (PCR) positive on
at least two occasions, or were PCR positive on one occasion and had clinical features of AIDS as defined by the revised
World Health Organization (WHO) clinical case definition for pediatric AIDS with the modification of persistent or severe
lower respiratory tract infection as a major sign (11). However, for the purposes of comparing clinical features in the
HIV-infected and uninfected groups, the 1986 WHO definition was used (12). Uninfected children were HIV
seronegative with at least one PCR negative test, or HIV seropositive with at least two negative PCR tests, or those who
subsequently seroreverted (on two different blood samples) and had at least one negative PCR. Indeterminate cases were
HIV seropositive with only one PCR negative test and had no symptoms of AIDS."
Apparently these kids took multiple PCR tests in some instances. I guess PCR tests aren’t 100 percent accurate so they do them more than once. And in cases where there was just one PCR positive they needed to also have clinical symptoms to be admitted to the HIV-infected group. Does that answer your question?
trueskeptic and Roger_Mexico:
Like OliverH, I feel I am not really accomplishing anything here. Every time I address one point, it is ignored and two more invalid points are brought up in its place.
The simple fact of the matter is that there is no current peer reviewed literature for the HIV dissent crowd. 15 year old papers are worthless. 5 year old papers are next to worthless.
You scream isolation. Isolation of HIV is routine. You claim it isn’t a retrovirus because it doesn’t “look” like one. I claim it is a retrovirus because it makes reverse transcriptase (which is the defining feature of retroviruses). You come up with a out-of-the-blue quotation that reverse transcriptase occurs “everywhere in nature.” This, to my knowledge, is false.
Yes, there are thousands of interspersed repeats of retroviral origins in the genome. Last I check, exactly one made a functional protein (syncytin from HERV-W). There is no endogenous reverse transcriptase activity anywhere except from infectious retroviruses, and I challenge you for a citation.
We go in circles about the ELISA. Stop with it already. We already know it is a crap test. But it works. Today you come with nitpicking the dilution of sera. Nearly every antibody test out there depends on a dilution series (to calculate a titer), and 1:300 is not a big dilution when 1:10,000 dilutions are considered positive in some tests, namely influenza.
You don’t like PCR assays, so you produce one study from 1992 or 1997 or whatever that shows it non-reproducible. Never mind the 20 or 30 other studies which have found it reproducible.
(4 since December!)
I have always sung about the protease inhibitors and their utter revolution of the field of HIV medicine. The only rebuttal you have produced to date is a possibly slanted account of comments made in a question and answer session from a Gordon Conference in 1996, before protease inhibitors went into widespread clinical usage. This is not science. This barely qualifies as a conspiracy theory.
I’ll monitor this debate and I will answer directed questions. I will not reply to blocks of text copied and pasted from aliveandwell.org, virusmyth.org, or any other slanted HIV dissent site. I will respond to questions raised in the primary literature and because I am feeling generous, I’ll accept stuff from Duesberg and pals’ reviews published in the scientific journals. That amounts to well over 100 papers, so we shouldn’t be short on discussion topics. Many (like the J Biosci artcile) are available free. If you want to debate science, we will debate science.
Science, above everything, is the practice of evaluating all data with an unbiased eye. To be a scientist, one must approach a set of data without any preconceived notions, and make up one’s mind based on the data. The data must be left to speak for themselves.
The HIV dissent are most emphatically not doing this. They use 4 papers, plus a couple of other contrary findings in isolated reports scattered throughout an ocean of good science to support a very mechanistically tenuous hypothesis. They add to this a large amount of obfuscation and distortion. One report on PCR shows it may or may not be reproducible, never mind the 30 others which show that it is. ELISA cannot be used to rule in HIV but it is quite good at ruling out HIV. The HIV dissenters claim that it is worthless by only looking at the rule-in capability. When all else fails, they cry academic dishonesty and resort to character smears.
This is exactly the course of the creationist people. Sometimes they harp on pieces that evolution people are actively debating. Sometimes they obfuscate and distort the science. Usually, it brings no support for the alternate hypothesis or creationism, but to them any attack on evolution must validate creationism. The HIV people do the same: the ELISA is bad, so drugs cause AIDS. AZT has nasty side effects and was originally designed as an anti-cancer drug, so drugs or malnutrtion causes AIDS.
Like ambushed says. Creationists are idiotic and at worst diminish people’s understanding of science and rot the educational system with their faith presented as science. HIV dissenters do much worse. From the Foo Fighters (convinced by Maggione) telling young fans not to get tested for HIV to Thabo Mbeki and two years of failing to endorse free AZT even for pregnant women, they are directly responsible for people’s deaths.
So unless you come back here with science, not virusmyth or aliveandwell.org, I will ignore you, and I encourage others to do likewise. Like Gallo, Ho, and Montagnier, I will not bring more publicity to your rantings. Without our postings, this thread will hopefully fade away before it puts wrongminded ideas into impressionable people’s heads. All actions have consequences and I will let you live with the blood on your hands.

I’m kind of puzzled by your response (forgot to mention this in the other post). I wrote:
“But I did find that the definition of “HIV-infected” used to group the children INCLUDED checking clinical measures of bad health in some cases. Thus one is not justified in pointing at worse health in the HIV-infected group and saying HIV is the reason. (Which the study wasn’t trying to argue anyway.)”
And I then went on to give the quote.
Note the word INCLUDED above (caps added for emphasis this time). So your statement:
"You noted that the paper used “clinical signs” of HIV as a classification of HIV infection. What the paper actually used was PCR positivity plus signs of HIV. "
is unnecessary. I knew and wrote the definition before. What is your point?
You ask “So I asked for you to explain how someone can be PCR positive for a virus and not be infected with the virus.”
This question is irrelevant to our discussion. What matters is that the researchers in the study you cited felt it necessary to have clinical signs of HIV infection given only one PCR positive result to put the kid in the HIV-infected group. And since they did that they biased the sample of the HIV-infected group torwards being unhealthy.
Looks like you need a literacy 101, since the fact that your reading comprehension is lacking is not an argument.
And your history is sorely lacking, too. Otherwise you would realise that Koch wrote his postulates before the advent of molecular biology.
Hogwash. Diseases have been well-demonstrated to go dormant, a time during which they are extremely hard to detect
Outdated. The genome has been isolated.
So you’re advocating experiments on humans. You volunteer?
Your ignorance of molecular biology is not an argument.
False. But thanks for telling us you don’t have the slightest idea how antibodies are produced.
Since you seem oblivious of that fact: THE HUMAN GENOME HAS BEEN DECODED, IF IT WAS HUMAN, IT WOULD BE ENCODED IN THERE.
Yeah, right. Like your claim that postulating an HIV-AIDS connection was illegal in Germany.
These articles debunk nothing, since they contain no data whatsoever, but merely outdated rants by people who are not actively following the field anymore.
Thanks for proving that your only argument is dishonesty. You claimed that the court decision showed it was illegal to postulate an HIV-AIDS connection. Such is impossible as per the german constitution. No court has the authority to do so.
Second, you knew you lacked expertise in German law. As such, there was no means for you to verify the accuracy of the data. That IS unreliable by any standards.
You are not applying scientific standards of any kind, and frankly, I doubt that you ever published anything, because your methods of data acquisition befit a propaganda minister, not a scientist.
You have been unable to produce any current, accurate data, and are only capable of citing personal opinions that have not been reviewed by anyone else, all the while lacking the expertise of assessing their accuracy yourself. Your claims have repeatedly been debunked, but you simply ignore any evidence to the contrary. You are not applying rigorous scientific standards. You are applying demagogic standards.
**
OliverH, first let me apologize for my tone in some of my posts last night. After a while it’s hard not to start dishing it out.
The paper you sent me to was a link with an image purporting to be of an HIV sequence, with information on the sources. I don’t remember whom I asked the question: which version of HIV is it? since there’ve been disagreements about its length; and how do we know it’s even HIV, given it’s never been isolated - I know, a sore point here.
I am not disputing PCR itself, but how it is used. Even if HIV has been isolated, it has never been used as a gold standard for any HIV diagnostic test, including PCR. bDNA uses QC-PCR as a gold standard; QC-PCR uses PCR as a gold standard; regular PCR uses antibody tests as a gold standard, and antibody tests use each other. Does this strike you as a scientific method?
The results of their study cannot be dismissed simply because “newer” results are available. What is needed - and perhaps this is included in the newer studies - is an explanation of the flaws in the older study.
My point is that fundamental flaws that were pointed out twenty years ago don’t go away just because they are ignored and not pointed out again every month. And the complaint that these criticisms are not published in enough peer-reviewed literature is self-fulfilling, since the industry considers them nuts. (cough - SMON - cough)
To any lurkers who might still think these flagrant truth-denialists like "ambushed are being at all intellectually honest, fair, and rational, I urge you to compare their incredibly credulous and disingenuous rhetorical ploys with those of the so-called SMON “scientists”. Exchange the technical terms and such between them, and they’re virtually identical!

Hmmm. Didn’t take much to correct your post.
Answered previously; some theories here.
Yes (and nothing else, please ;))
- Is the claim “there are many smokers who do not develop cancer” true? Anyone?
- Cigarette smoking is different because it is a risk factor rather than an allegedly killer retro/virus that … er … only sometimes kills. After a long time. Mostly. Well, if we could find it without multiplying some unknown DNA millions of times, the picture would be clearer.
Your quite deliberate obtuseness was never more in evidence than in this gem of a quote. It exposes the fact (as if it was not screamingly evident already) that:
1: You really have no true comprehension of what you are posting about
2: You have no cogent notion of how research in the hard sciences is conducted and the process whereby research hypotheses, theories and paradigms are evaluated and accepted, corrected or discarded.
3: You are essentially relying on rhetorical babble at this point and edwino and OliverH have the patience of saints.
Your insanely silly arguments predicated on obsolete research are being dis-assembled like tinker toys by thread respondents llike edwino and OliverH who have the scientific background to deconstruct the asininity of flogging decade+ old studies in a field where the base of knowledge and power of diagnostic procedures are evolving so fast that 3 years ago is horse and buggy days, 5 years ago is the relative middle ages, and 10 years ago is the age of the dinosaurs. And you’re banging the drum about questions asked 10 and 20 years ago that you deem to be insufficiently answered? Each anthropology or geology article in Scientific American does not preface the introduction with the newsflash that the earth really is more than 6000 years old. It’s simply accepted that new methods and understandings have rendered the old notions non-operational.
In the modern process of conducting scientific research it is (common sensically) generally considered a waste of time, effort and resources to go back and spend a significant effort deconstructing old hypotheses and theories where new research discoveries, using more powerful methods and hardware to yield more accurate results, have rendered the old hypotheses essentially irrelevant by generating more relevant and accurate information about the process of the disease being investigated. The old, less accurate or inaccurate hypotheses and theories are simply considered to be either irrelevant, or to have been corrected and superceded by new information and more powerful and accurate theories and paradigms.
Given in the text.
As I already showed you, the genomes of HIV 1 and HIV 2 indeed differ in length.
It’s funny how patients infected with HIV 1 and HIV 2 happen to have this strange DNA in them which clearly isn’t human, but rather viral, encodes the proteins used in protein-based HIV tests, with closely related, but distinct genomes.
The gold standard for protein based tests nowadays more often than not is a purified protein, or even a purified recombinant protein, which has never seen the organism it originally comes from.
Precisely how do you suppose a DNA based test uses a protein based test as a gold standard?
Again, I don’t think you are familiar with how scientific publication works. Newer studies don’t specifically point out flaws in older ones. They provide THEIR data and show how it fits in the context of other available data. It is up to the authors of the older data to show that their conclusions are not invalidated by the newer data, because their conclusions have to be able to predict the new data. If data is generated that contradicts a previous study, that study is by definition considered inferior pending demonstration that it doesn, in fact, explain the newer data.
And my point is that flaws pointed out for experiments done twenty years ago are rendered moot when new methods have confirmed the old results.
Again, the example of Stanley Prusiner proves you wrong. His claims were much, **much[/b more radical than Duesberg’s. Where Duesberg merely claims there might be compund different sources for AIDS than a virus,
he is still assuming standard ways of pathogenicity. Prusiner did something else: It was commonly accepted that replicating pathogenicity, at its base, always required a nucleid acid. A virus has nucleic acids, bacteria have nucleic acids. Bang, there comes Prusiner and claims that proteins alone can adopt pathogenicity and replicate. Such a claim was totally outrageous, since people didn’t see a way how a protein could ‘replicate’ or increase the number of pathogenic molecules. Yet Prusiner’s data was solid. He DID get published. And even though some critics were still howling, he was awarded the Nobel Prize. Nowadays, only a few years later, prions are pretty much generally accepted, and a lot of researchers who, ten years ago, vehemently denied such a thing could exist, jumped onto the bandwaggon.
Thanks for your vacuous, babbling reply. It’s interesting that this discussion seems to have taken on a religious tenor for you, thus your canonization of edwino and OliverH.
Your frothing emotionalism, however, serves little to advance the discussion, whereas St. edwino and others have actually proferred some interesting rebuttal material. You are, of course, welcome to simmer down and attempt some semblance of rational inquiry.
:rolleyes:
As long as we say “There are many smolers who do not develop smoking-related cancer”, I’d say yes. Atleast inasmuch as it is never diagnosed. Technically, if you’re a man and beyong 65, chances are pretty high that you have cells in your prostate that technically qualify as ‘cancer’, but don’t grow quickly enough to be reason for any concern, and are totally unrelated to smoking. The biggest ‘cause’ of cancer is old age.
A virus in and of itself is also’ only a risk factor’. A virus does not automatically lead to an infection, it all depends on the dosage, the type of contact etc. At the same time, cigarette smoke isn’t ‘only a risk factor’. The substances in cigarette smoke DO damage DNA. However, it needs to damage the right areas in the right DNA to actually push you towards cancer.
Interesting new papers relating the issue of new tests (and virus isolation):

A modified ultrasensitive assay to detect quantified HIV-1 RNA of fewer than 50 copies per milliliter.
Piwowar-Manning EM, Henderson TA, Brisbin L, Jackson JB.
Department of Pathology, Johns Hopkins Medical Institutions, 600 N Wolfe St, Carnegie Bldg, Room 415, Baltimore, MD 21287, USA.
We compared the sensitivity and specificity of versions 1.0 and 1.5 and a modified version 1.5 of the AMPLICOR HIV-1 MONITOR ultrasensitive RNA assay (Roche, Indianapolis, IN) by using a virus stock dilution series and plasma samples from HIV-1-infected and uninfected subjects. The modified assay was linear and consistently positive down to 12 copies per milliliter vs 25 copies per milliliter for the other 2 assays. Versions 1.0, 1.5, and modified 1.5, respectively, detected 9 (23%) of 39, 11 (28%) of 40, and 43 (61%) of 71 replicates of a 4-copy-number and 11 (28%) of 40, 17 (46%) of 37, and 88 (90%) of 98 replicates of a 10-copy-number standard. Of 44 patient samples with undetectable levels using version 1.0, 32 (73%) had detectable levels on the modified assay, and 5 (25%) of 20 had detectable levels on version 1.5. None of the assays detected HIV-1 RNA in HIV-1 antibody-negative samples. The modified version 1.5 of the RNA assay is more sensitive for detecting HIV-1 RNA in significantly more patients than are versions 1.0 and 1.5.

Development of a new less-sensitive enzyme immunoassay for detection of early HIV-1 infection.
Rawal BD, Degula A, Lebedeva L, Janssen RS, Hecht FM, Sheppard HW, Busch MP.
Blood Centers of the Pacific, San Francisco, California 94118, USA.
The sensitive/less-sensitive (S/LS) enzyme immunoassay (EIA) testing strategy for discriminating “early” from “longstanding” HIV infection has been widely applied for detecting recent seroconverters and estimating HIV incidence rates. The originally developed assay (3A11-LS EIA; Abbott Laboratories, Abbott Park, IL) involved performance of LS EIAs using a bead-based assay that required specialized equipment and reagents of limited availability. In contrast, 96-microwell-based EIAs are more universally applied for HIV serodiagnosis throughout the world. The authors report development and preliminary validation of an LS protocol using an EIA in a 96-well format: the Vironostika HIV-1 MicroElisa System (Vironostika-LS EIA; Bio Merieux, Raleigh, NC). The results with samples from recent HIV-1 seroconverters, persons with longstanding HIV-1 asymptomatic infection, patients on highly active antiretroviral therapy, and AIDS patients show a high degree of correlation between the Vironostika-LS EIA and 3A11-LS EIA. The authors also demonstrate that the Abbott 3A11-LS EIA and Vironostika-LS EIA performed comparably on HIV-1-positive samples from persons infected with non-B HIV-1 subtypes. These results support the potential use of the Vironostika-LS EIA for detection of recent HIV-1 infections for incidence projections and for other epidemiologic, clinical, and molecular surveillance applications.

Performance characteristics of the TRUGENE HIV-1 Genotyping Kit and the Opengene DNA Sequencing System.
Kuritzkes DR, Grant RM, Feorino P, Griswold M, Hoover M, Young R, Day S, Lloyd Jr RM Jr, Reid C, Morgan GF, Winslow DL.
Division of Infectious Diseases, University of Colorado Health Sciences Center, Denver, Colorado, USA. dkuritzkes@partners.org
The TRUGENE HIV-1 Genotyping Kit and OpenGene DNA Sequencing System are designed to sequence the protease (PR)- and reverse transcriptase (RT)-coding regions of human immunodeficiency virus type 1 (HIV-1) pol. Studies were undertaken to determine the accuracy of this assay system in detecting resistance-associated mutations and to determine the effects of RNA extraction methods, anticoagulants, specimen handling, and potentially interfering substances. Samples were plasma obtained from HIV-infected subjects or seronegative plasma to which viruses derived from wild-type and mutant infectious molecular clones (IMC) of HIV-1 were added. Extraction methods tested included standard and UltraSensitive AMPLICOR HIV-1 MONITOR, QIAGEN viral RNA extraction mini kit, and QIAGEN Ultra HIV extraction kit, and NASBA manual HIV-1 quantitative NucliSens. Sequence data from test sites were compared to a “gold standard” reference sequence to determine the percent agreement. Comparisons between test and reference sequences at the nucleotide level showed 97.5 to 100% agreement. Similar results were obtained regardless of extraction method, regardless of use of EDTA or acid citrate dextrose as anticoagulant, and despite the presence of triglycerides, bilirubin, hemoglobin, antiretroviral drugs, HIV-2, hepatitis C virus (HCV), HBV, cytomegalovirus, human T-cell leukemia virus type 1 (HTLV-1), or HTLV-2. Samples with HIV-1 RNA titers of >or=1,000 copies/ml gave consistent results. The TRUGENE HIV-1 Genotyping Kit and OpenGene DNA Sequencing System consistently generate highly accurate sequence data when tested with IMC-derived HIV and patient samples.
And as far as treatment effectivity is concerned:

Dynamics of viral load rebound in plasma and semen after stopping effective antiretroviral therapy.
Liuzzi G, D'Offizi G, Topino S, Zaccarelli M, Amendola A, Capobianchi MR, Perno CF, Narciso P, Antinori A.
National Institute for Infectious Diseases L. Spallanzani, Rome, Italy.
A rebound in the plasma and seminal viral load was detected in 12 patients after the interruption of effective highly active antiretroviral therapy. The viral rebound was generally higher in plasma, although the highest level observed during interruption was higher in semen in two patients. The reintroduction of therapy was followed by an overall decrease in HIV-RNA in plasma and semen. One to 2 months after restarting treatment, four out of seven patients showed undetectable HIV-RNA in semen.
Let’s take a trip to a few days ago where you started out here -
Your agenda is as transparent as is your apparent inability to grasp the current relevant data regarding the disease process being discussed. Your desperate and disengenous handwaving exercises to distract attention from the point that you have no real clue or understanding what you posting about and referencing, are becoming so frantic you are about to take flight.
You present the distasteful sight of a cornered, poo flinging con man, oddly compelling to observe and yet reasonable people are compelled to keep their distance for fear of spatter.
Thanks, O., certainly some food for thought. Might be a while to get back to you on these.
