| certificate of analysis sigma aldrich: PET Chemistry P.A. Schubiger, L. Lehmann, M. Friebe, 2007-01-19 Personalized medicine employing patient-based tailor-made therapeutic drugs is taking over treatment paradigms in a variety of ?elds in oncology and the central nervous system. The success of such therapies is mainly dependent on ef?cacious therapeutic drugs and a selective imaging probe for identi?cation of potential responders as well as therapy monitoring for an early bene?t assessment. Molecular imaging (MI) is based on the selective and speci?c interaction of a molecular probe with a biological target which is visualized through nuclear, magnetic resonance, near infrared or other methods. Therefore it is the method of choice for patient selection and therapy monitoring as well as for speci?c e- point monitoring in modern drug development. PET (positron emitting tomography), a nuclear medical imaging modality, is ideally suited to produce three-dimensional images of various targets or processes. The rapidly increasing demand for highly selective probes for MI strongly pushes the development of new PET tracers and PET chemistry. ‘PET chemistry’ can be de?ned as the study of positron-emitting compounds regarding their synthesis, structure, composition, reactivity, nuclear properties and processes and their properties in natural and - natural environments. In practice PET chemistry is strongly in?uenced by the unique properties of the radioisotopes used (e. g. , half-life, che- cal reactivity, etc. ) and integrates scienti?c aspects of nuclear-, organic-, inorganic- and biochemistry. |
| certificate of analysis sigma aldrich: Transmutations--alchemy in Art Lawrence Principe, Lloyd DeWitt, 2002 Alchemy is one of the most evocative subjects in the history of science. Alchemy made important contributions to the development of modern science while firing popular imagination so strongly that portrayals of the alchemist at work pervaded the arts. The more celebrated goals of alchemy, like transmutation of base metals into gold, still tease and tantalize. Transmutations offers a thoughtful look at the role of the alchemist in the 17th and 18th centuries, as depicted in a selection of paintings from the Eddleman and Fisher Collections housed at the Chemical Heritage Foundation. This beautiful full-color book reveals much about the beginnings of chemistry as a profession. |

| certificate of analysis sigma aldrich: Stem Cell and Biologic Scaffold Engineering Panagiotis Mallis, 2019-10-04 Tissue engineering and regenerative medicine is a rapidly evolving research field which effectively combines stem cells and biologic scaffolds in order to replace damaged tissues. Biologic scaffolds can be produced through the removal of resident cellular populations using several tissue engineering approaches, such as the decellularization method. Indeed, the decellularization method aims to develop a cell-free biologic scaffold while keeping the extracellular matrix (ECM) intact. Furthermore, biologic scaffolds have been investigated for their in vitro potential for whole organ development. Currently, clinical products composed of decellularized matrices, such as pericardium, urinary bladder, small intestine, heart valves, nerve conduits, trachea, and vessels, are being evaluated for use in human clinical trials. Tissue engineering strategies require the interaction of biologic scaffolds with cellular populations. Among them, stem cells are characterized by unlimited cell division, self-renewal, and differentiation potential, distinguishing themselves as a frontline source for the repopulation of decellularized matrices and scaffolds. Under this scheme, stem cells can be isolated from patients, expanded under good manufacturing practices (GMPs), used for the repopulation of biologic scaffolds and, finally, returned to the patient. The interaction between scaffolds and stem cells is thought to be crucial for their infiltration, adhesion, and differentiation into specific cell types. In addition, biomedical devices such as bioreactors contribute to the uniform repopulation of scaffolds. Until now, remarkable efforts have been made by the scientific society in order to establish the proper repopulation conditions of decellularized matrices and scaffolds. However, parameters such as stem cell number, in vitro cultivation conditions, and specific growth media composition need further evaluation. The ultimate goal is the development of “artificial” tissues similar to native ones, which is achieved by properly combining stem cells and biologic scaffolds and thus bringing them one step closer to personalized medicine. The original research articles and comprehensive reviews in this Special Issue deal with the use of stem cells and biologic scaffolds that utilize state-of-the-art tissue engineering and regenerative medicine approaches. |

| certificate of analysis sigma aldrich: Conference Research Topic: 16th International Symposium on Schistosomiasis Roberta Lima Caldeira, Thiago Almeida Pereira, Cristina Toscano Fonseca, Marina Moraes Mourão, 2024-08-28 Schistosomiasis is a major health problem in many tropical areas in the world. This neglected tropical disease is endemic in 78 countries and affects over 250 million worldwide. In 2021 the World Health Organization published the document “Ending the neglect to attain the Sustainable Development Goals: a road map for neglected tropical diseases 2021−2030”, which established as goals for schistosomiasis (i) elimination of the disease as a public health problem in 78 affected countries by 2030, and (ii) elimination of transmission in 25 endemic countries by 2030. However, to achieve these goals, it is necessary to better understand the disease and its dynamics, the parasite's immunobiology, and its relationship with the definitive and intermediate hosts. This will allow for the development of vaccines, more effective/alternative drugs, precise diagnostic methods, and improved strategies to prevent, control, and eventually even eliminate this devastating disease. Since 1987 the Oswaldo Cruz Foundation (Fiocruz, Brazilian Ministry of Health) has organized the International Symposium on Schistosomiasis on a biennial basis. Historically, this symposium brings together approximately 350 people, accounting for world-renowned scientists, public health managers, students, and policymakers, to translate the knowledge generated in research institutions into actions and tools to improve the quality of life of the population affected by schistosomiasis. Unfortunately, due to the COVID-19 pandemic, the symposium had to be postponed. In order to continue the discussion on schistosomiasis in these difficult times, the organizing committee of the event launched a Pre-conference Research topic (Pre-Conference Research Topic: 16th International Symposium on Schistosomiasis) where scientists could share their latest discoveries with the community. With the advent of vaccines and other public health strategies implemented across the globe, we are pleased to announce that The 16th edition of the International Symposium on Schistosomiasis will be held in person between 21 and 23 November 2022, in Ouro Preto, Minas Gerais, Brazil. We would like to invite our colleagues that intend to attend the Symposium to submit their contributions. In addition, submissions from scientists that would not be able to join us in Ouro Preto in November are also welcome. |

| certificate of analysis sigma aldrich: Manual of Standard Operating Procedures for Selected Chemical Residue and Contaminant Analysis Food and Agriculture Organization of the United Nations, International Atomic Energy Agency, 2021-09-15 Food safety is an important global public health and trade matter, with chemical hazards occupying centre stage due to associated acute and chronic health outcomes. There is also an increasing need to address antimicrobial resistance concerns. While food remains a major vehicle for exposure to these hazards, related matrices cannot be ignored. Animal feed for instance may contain drug or pesticide residues as well as mycotoxins that could carry-over to food either as parent compounds or their metabolites of toxicological relevance. Contaminated water is also another medium of potential exposure to food hazards. A concerted effort is required to address the need for a safe food supply and one critical stakeholder is the testing laboratory. While this requires trained and capable analysts as well as reliable instrumentation, analytical methods are a major need. Development and validation – to ensure fitness of purpose – and availability of these methods is a necessity. This manual, consisting of several Standard Operating Procedures (SOPs), presents another opportunity for laboratories to address gaps in analytical methods and/or expand their options. The manual contains techniques for analyzing certain mycotoxins such as aflatoxins, fumonisin and ochratoxin in matrices that include milk, edible vegetable oil and animal feed etc. A range of veterinary drug residues including permitted and prohibited substances in animal matrices including fish, are also addressed. Several pesticide residues in cereals, fruits and vegetables are also covered. A couple of methods for analysis of selected metals are also presented. |

Glycerol enhancement has therefore become a priority to improve the sustainability of the biodiesel industry. Nevertheless, the multifunctionality of glycerol makes it a promising precursor for different types of production (fuel/biofuel, chemical products). This conversion has therefore become a subject of multifaceted research that requires an exchange of knowledge across many sectors. In this book, different disciplines (chemistry, biology, engineering, etc.) have been taken into consideration to propose an interdisciplinary point of view on different aspects. |
