Successes vs. Failures

It can again be asked, if plants and herbs and nutrition are said to be so successful in some cancer cases, or in even some few cancer cases, why are they not successful in all cancer cases A conjecture of course is that these plants or plant-derived substances somehow trigger the immune system, and every individual is different. Furthermore, a person s immune system does not ordinarily recognize that person s own cancer cells. In other words, the cancer cells mimic the normal cells. Only if cancerous cells from another person are introduced does an attack by the immune system occur. This is why immune suppressants must be used for organ transplants. Research is proceeding, however, on how to make cancerous cells reeognizable to the person s own immime system. There has been limited success against melanoma, as previously described in the Stephen S. Hall references. 

The subject of plant and herbal treatments for cancer, and most of the other options for that matter, can be viewed as remaining mostly a gray area, with as yet no large-scale groundswell of pnblic opinion demanding a no-nonsense, definitive resolution for, say, plant or herbal nsage and other alternatives. 

As for hard figures for success rates, or remission rates, the facts mostly seem in abeyance. A quote by Patriek MeGrady, founder of CANHELP, is perhaps enlightening (Walters, 1993, p. 5ff) Most alternative therapies are almost totally useless — just like the conventional therapies.  

Michael Lemer (1994) reported similar impressions. After traveling worldwide visiting doctors and clinics, Lemer gives the impression that alternative cancer therapies and conventional therapies have about the same overall success rates, although alternative treatments have an element of secrecy and a dearth of records. 

Another interesting piece of information is that a stndy showed that where there was a so-called spontaneons remission of cancer, most of the patients (88%) had made major dietary changes, for example, to vegetarianism (Walters, 1993, p. 3). However, statistically speaking within the totality of cases, Walters makes the observation that the overall survival rates are about the same, with or without treatment.

A criterion of mechanism based on the Hammett acidity function, H0 (Section 3.2, p. 130),has long been used to decide the type of question raised by the choice between Mechanisms I and II in Scheme 8. Since in strongly acidic media the concentration of the protonated substrate should be proportional to h0, the reaction rate for a unimolecular decomposition of this protonated substrate (Mechanism I) should also be proportional to h0, whereas if a water molecule is required (Mechanism II), the rate should follow H30+ concentration instead. This test, known as the Zucker-Hammett hypothesis,76 when applied to acetal and ketal hydrolysis, appears to confirm the A-l mechanism, since a linear relationship is found between rate constant and h0 at high acidity.77 Inconsistencies have nevertheless been found in application of the Zucker-Hammett hypothesis, for example failure of the plots of log k vs. — H0 to have the theoretical slope of unity in a number of cases, and failure to predict consistent mechanisms for forward and reverse reactions the method is therefore now considered to be of doubtful validity.78 Bunnett has devised a more successful treatment (Equation 8.45), in which the parameter to measures the extent of... 

Without the need of completeness, we discuss the most state-of-the art structure-based VS that are generally used at pharmaceutical industries during the drug discovery process. Our attempt was also to give a picturesque overview on the structure-based VS process and show its effectiveness or its failures through a case study and some success stories during the CADD processes.

Flex Life n Informally, the number of bending-reversal cycles causing a part to fail in a particular service. Most specifically, the number of cycles to failure of a test specimen repeatedly bent in a prescribed manner. The ASTM test for plastics is D 671. The specimen, molded or cut from sheet, is subjected to load reversal at 30 Hz at a predetermined level of outer-fiber stress until it either fails or the test is discontinued. By setting up different stresses for successive specimens, one can develop a graph of stress at failure vs number of cycles to failure (usually plotted on semilogarithmic coordinates), i.e., the flex-life curve of fatigue curve. 

In a retrospective study of 319 patients, multivariate analysis identified shock on ICU admission day as the only independent predictor for PMV (>21 days) (47). In a prehminaty study of 111 patients, increased duration of MV and need for transfer to a long-term ventilator care facility was associated with a creatinine elevation of 1.3 mg/dL anytime during the ICU stay (48). In another study, none of the 52 patients with PMV and renal failure were successfully weaned (49). Chao and colleagues reviewed >1000 patients transferred to their regional weaning center and identified 63 with renal dysfunction, with creatinine >2.5 mg/dL (40 on renal replacement therapy) (50). When compared to those with creatinine <2.5 mg/dL, patients with renal dysfunction were less likely to wean from MV (13% vs. 58%).
