Abstract The growth of the Lithium Polymerization Catalysts system has been an interesting and intriguing study. Abraham Lincoln, in one of his addresses, indicated that no one would long remember what was said or done there on that occasion. Thus unwittingly, he may have forecast the insignificance of this paper in its effect on the scientific world. It is presumed that none of you here, unless he may have been a Charles Goodyear medalist, can recall many of the important statements or thoughts expressed on this occasion by prior Charles Goodyear Medalists. Therefore, you need not recall anything that is said here today. When one starts a research project, the first thing that is done is to review the literature to find out what has already been done in that field. Thus, we find that in 1826, Faraday published his first analysis of rubber latex. He found that it contained water, rubber, vegetable matter rich in nitrogen and extractable material. He also established that rubber contained the elements of Carbon and Hydrogen. His was the first significant publication about rubber since that of de la Condamine in 1751 to the Academie of Science in Paris. There were several other publications prior to the end of that century, but they did not seem too significant from a scientific standpoint. A German scientist, Frederich Karl Himly, had been studying in Göttingen for a year and a half, about rubber and its destructive distillation products, and he discussed his findings in his Doctors dissertation in 1835. Himly's thesis was published in a small paper back booklet but it did not get wide distribution, possibly due to the fact that it was written in Latin, as was often the case in those days. A copy of this publication was found in the Research Library of The Firestone Tire & Eubber Company about 1922. Imprinted on the cover was the name of M. J. Sehleiden and written on the outside, the name of M. Prinzhom. Also there was the name of C. C. Goodrich, and H. W. Kugler, who later became the Chief Chemist of The Firestone Tire & Rubber Company.

Coronavirus Disease 19 (COVID-19), due to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has become an on-going global health emergency affecting over 94 million cases with more than 2 million deaths globally. Primarily identified as atypical pneumonia, it has developed into severe acute respiratory distress syndrome (ARDS), a multi-organ dysfunction with associated fatality. Ever since its emergence, COVID-19 with its plethora of clinical presentations has signalled its dynamic nature and versatility of the disease process. Being a disease with droplet transmission has now assumed the proportion of a suspected airborne nature which, once proved, poses a Herculean task to control. Because of the wide distribution of the human angiotensin-converting enzyme-2 (hACE2) receptors, known for its transmission, we envisage its multiorgan spread and extensive disease distribution. Thus, an extensive review of the extrapulmonary organotropism of SARS-CoV-2 with organ-specific pathophysiology and associated manifestations like dermatological complications, myocardial dysfunction, gastrointestinal symptoms, neurologic illnesses, hepatic and renal injury is needed urgently. The plausible mechanism of site-specific viral invasion is also discussed to give a comprehensive understanding of disease complexity, to help us to focus on research priorities and therapeutic strategies to counter the disease progression. A note on the latest advancements in vaccine research will enlighten the scientific world and equip it for better preparedness.

In 1968, Sugimura and Yanagawa described a small 25 nm virus like particle in association with the Matsuda strain of infectious canine hepatitis virus (ICHV). Domoto and Yanagawa showed that this particle was dependent on ICHV for its replication in primary dog kidney cell cultures (PDK) and was resistant to heating at 70°C for 10 min, and concluded that it was a canine adeno-associated virus (CAAV). Later studies by Onuma and Yanagawa compared CAAV with the known human serotypes (AAV 1, 2, 3) and AAV-4, known to be associated with African Green Monkeys. Using the complement fixation (CF) test, they found that CAAV was serologically related to AAV-3 and had wide distribution in the dog population of Japan.

Based on the experiences of three research groups using and evaluating the Cognitive Interviewing Reporting Framework (CIRF), we draw conclusions about the utility of the CIRF as a guide to creating cognitive testing reports. Authors generally found the CIRF checklist to be usable, and that it led to a more complete description of key steps involved. However, despite the explicit direction by the CIRF to include a full explanation of major steps and features (e.g., research objectives and research design), the three cognitive testing reports tended to simply state what was done, without further justification. Authors varied in their judgments concerning whether the CIRF requires the appropriate level of detail. Overall, we believe that current cognitive interviewing practice will benefit from including, within cognitive testing reports, the 10 categories of information specified by the CIRF. Future use of the CIRF may serve to direct the overall research project from the start, and to further the goal of evaluation of specific cognitive interviewing procedures.
