Research 8 Development sample

The authors would like to thank all companies, which presented the samples for tests Dr. Igor Barsukov (Superior Graphite Co.) for his efforts in providing of our participation in the conference U. S. Civilian Research Development Foundation (CRDF) for financial support of our trip. 

As shown in Figure 7.2, most assays involve a common series of steps that must be completed in order to report results. These steps include sample receipt, method development, sample preparation, analysis, data processing, and data reporting. While most researchers focus on speeding the analysis step, any of these steps can become bottlenecks. Thus it is important to optimize the whole process. 

The research programme of the European Institute for Transuranium Elements was, from its very beginning, devoted to both basic research on advanced plutonium containing fuel and to fundamental research on actinide elements. Non-fuel actinide research in Europe started more than 20 years ago with the reprocessing of irradiated actinide samples. Since the first isolation and purification of transplutonium elements, actinide research developed steadily in close contact and cooperation with specialised laboratories in Western Europe and in the United States. 

O. K. Doolen, Instrument Development Division, Gulf Research Development Co., largely devised the multiple sample apparatus. P. Ross and W. Frazier obtained the experimental data discussed. 

Several FCC Research groups have made changes to the standard method, resulting in many different test methods (4). For instance, at Akzo Research we introduced the Ketjen-MAT test for the evaluation of production and development samples (5). 

In a 12-week, double-blind, randomized, placebo-controlled study in 40 patients with treatment-resistant schizophrenia (funded by Johnson Johnson Pharmaceutical Research Development), the addition of risperidone to clozapine improved overall symptoms and positive and negative symptoms (49). The adverse events profile of clozapine + risperidone was similar to that of clozapine + placebo. Clozapine + risperidone did not cause additional weight gain, agranulocytosis, or seizures compared with clozapine + placebo. All the patients completed 12 weeks of treatment however, the small sample size precluded definitive conclusions. 

As an example, an experimental rice herbicide (ERH-1), 2,2-dimethyl-l-(4mthylthio-5-pyrimidinyljindane, was advanced to phase 2 along with a request for a 3 kg sample. Typically expeditious delivery of the sample was required to meet a rapid development strategy, therefore the s)mthetic route (Scheme 1) developed by the discovery group would be utilized to fulfill the sample requirement The synthetic detail of the chemistry was published in the journal Organic Process Research Development, therefore the chemistry will not be discussed in this transcript... 

P. Chu (Mobil Research Development Corp., Paulsboro, N. J. 08066) I am very interested in the way you prepared the H-Y sample. Why did weakly acidic organic exchange resins have to be used What degree of exchange can you achieve without damage to the zeolite structure How stable thermally is the final H-Y sample ...

The sample that draws the greatest interest is human plasma, but other physiological human fluids, such as urine and bile, have also been the subject of analysis. To cover the needs of in vivo preclinical studies, many researchers developed methods for the determination of paclitaxel/docetaxel and their metabolites in samples from animal models such as rat and mouse. 

Research developing environmental methods might consider the use of AA detection. Perhaps some of the more interesting are detectors that use inductively coupled plasma (ICP) as an energy source and either atomic emission (AE) or mass spectrometry (MS) as the detector. ICP-AE and ICP-MS are well-developed analytical tools. Once of the major advantages of these techniques is that mixture of metals can be analyzed without the need for separation. Thus, workers who use these instruments normally do not think about their use as detectors. However, ICP-AE and ICP-MS cannot determine the oxidation or chemical state of a particular metal ion. Some samples are quite important from a toxicological and environmental standpoint since the... 

Development of chiral additives for asymmetric reduction is an on-going area of research. A sampling of some newer reagents include the reduction of acetophenone with a 227-borane complex, giving 228 in 88%... 

Once a product has been imported, it should be entered into the company s import system, either as a commercial product or a research and development sample, designating which type of certification is required, and whether it is subject to TSCA but exempt from the PMN requirements. While the same positive certification applies whether or not the product is required to be on the Inventory, make sure the company s systems distinguish between products that can be imported for commercial purposes and products that cannot. This is important for ensuring compfiance with the PMN requirements. 

As discussed in the PMN Exclusions and Exemptions Chapter, 5(h)3 of the Toxic Substances Control Act (TSCA) exempts from TSCA 5(a) and (b) (the PMN and Significant New Use rules, respectively) small quantities of new chemicals or chemicals subject to a Significant New Use Rule (SNUR), if used solely for research and development (R D) purposes underspecified circumstances. R D substances are often sampled for outside testing to laboratories or to customers. If the product is not on the TSCA Inventory, or is the subject of a SNUR, the R D substance must be sampled in a way that meets the TSCA exemption requirements for research and development samples. TSCA s PMN rules apply to manufacturers and importers SNURs apply to processors as well as manufacturers and importers.
