A bold exposé of how the very foundation of toxicology has been contaminated by sexist and racist ideologies The first critical understanding of the field of toxicology from a feminist and antiracist perspective, Toxic Sexual Politics asserts that the science of toxicants must be held accountable for the uneven distribution of toxic pollution along racial and sexual lines. Drawing upon in-depth interviews and extensive ethnographic and archival research, including participant observations in toxicology classrooms, conferences, and laboratories, Melina Packer urges environmental health advocates to place toxicant science within its masculinist, militarist, and eugenicist history. Toxic Sexual Politics shows how the founding fathers of U.S. toxicology were ideologically aligned with the chemical industry, inventing a science that could "make chemicals safe," as opposed to one that could adequately protect planetary health from toxicants' hazards. While many toxicologists today are critical of the chemical industry, they continue to rely on the highly limited tools of toxicology as accurate measures of toxicity, as do government regulators, the courts, and environmental advocates. Unlike most critiques of the chemical industry and narratives of environmental health movements, Toxic Sexual Politics refuses to take the science at face value. By focusing on the sexist, racist, and ableist biases reinforced by toxicology, Packer powerfully argues that this scientific discipline reproduces the very same white supremacist and heterosexist logics that generated environmental injustices in the first place. The field of toxicology can explicitly confront chemical corporate power by building from queer, feminist, anti-ableist, and antiracist movements for environmental and reproductive justice.

This book provides an overview of Data Monitoring Committees(DMC) - what was done in the past, what is currently being done, and thoughts on improvements for the future. Previous works focused primarily on large cardiovascular studies (where DMCs originated more than 30 years ago) but updated references are needed that discuss smaller, more flexible studies in areas such as oncology. The authors have attended ~800 DMC meetings from ~200 distinct studies across all areas of clinical studies (oncology, rheumatology, rare diseases, cardiology, immunology, etc.) This wide range of expertise will be used, as well as the expertise that comes from working with virtually every large biotechnology and pharmaceutical company and CRO for DMC work. The reader of the book will know when DMCs are needed or helpful, how to form the DMC, how to work with external CROs and with sponsor teams and the DMC to create needed DMC outputs, how the DMC meetings are conducted, and - especially for DMC members - what are considerations within the Closed Session to review safety/efficacy outputs to assess risk/benefit to make appropriate recommendations that protect the patient safety and trial integrity.This is a practical hands-on book on how to decide if a DMC is necessary, how to form the DMC, how to expertly create the necessary materials for the DMC and have smooth running DMC meetings. There is no specialized training in school about how DMCs work - frequently people may have been in industry for many years without ever needing to work with a DMC. This book is the helpful reference for those new to these DMCs. The DMC work is critical to be correctly implemented as the impact of DMC activity on safeguarding the trial is so important.This book provides the following:Provides thorough instructions on the steps needed to form and implement a Data Monitoring Committee for clinical trial evaluation;Includes practical and hands-on information on DMC implementation;Discusses a wide range of clinical trial - by phase and therapeutic area.

Zwischen Orient und Okzident, zwischen Iran und Bundesrepublik, zwischen Wissenschaft und Unternehmertum - Djamshid Hossein Pour blickt zurück auf ein Leben, das im Iran unter dem Schah begann und ihn nach Deutschland führte. Dabei fasst er die Erkenntnisse zusammen, die ihn geleitet haben. Seine Grundthemen sind der Schutz des Lebens, eine kritische und weltoffene Haltung als Naturwissenschaftler, Bildung als entscheidende Ressource und ein Beheimatetsein in mehreren Kulturen.Als Spezialist für die Analyse hochtoxischer Substanzen und Experte des UN-Umweltprogramms UNEP erkannte er, wie sehr die Zukunft unseres Planeten von der kulturübergreifenden Zusammenarbeit der Wissenschaften und der Menschheit abhängt. Seine Geschichte beginnt in den Gassen Teherans und den umgebenden Bergen und ist mehr als nur eine erfolgreiche Migrationsgeschichte - es ist eine Geschichte darüber, wie wir uns gegenseitig bereichern, uns am Leben halten, von toxischen Stoffen und Ideologien fernhalten und den Wert der Freiheit würdigen.Die Autobiografie eines erfolgreichen iranisch-deutschen Wissenschaftlers und Unternehmers ist zugleich ein Debattenbuch, das angesichts neuer globaler Spannungen lange nachhallen wird.

Das Führen von Kraftfahrzeugen im Straßenverkehr unter dem Einfluss von Drogen ist eine Thematik, die vor dem Hintergrund aktueller Statistiken zu Fahrten unter dem Einfluss von berauschenden Mitteln von Jahr zu Jahr brisanter wird. Insbesondere vor dem Hintergrund der im April 2024 erfolgten Teillegalisierung von Cannabis und der im August 2024 eingeführten neuen Tatbestände des StVG spielt nicht nur das weiterhin verbesserungsfähige polizeiliche Erkennen der sogenannten "folgenlosen Drogenfahrten" eine Rolle, sondern vielmehr auch die steigende Relevanz des Konsums "anderer berauschender Mittel" als polizeilich erkannte Unfallursache.Die Problematik berührt insbesondere die mit dem Rechtssachverhalt "drogenbeeinflusster Fahrer" praktisch und juristisch befassten Behörden und Institutionen. Eine Aktualisierung und Vertiefung der Aus- und Fortbildung ist für alle Beteiligten dringend notwendig.Der vorliegende Leitfaden betritt auf diesem nur interdisziplinär zu begreifenden Gebiet in seiner inhaltlichen Konzeption und Gestaltung Neuland. Die Autoren zeichnen aufgrund ihrer fachlichen Expertise für die polizeiliche, verkehrsmedizinische, verkehrspsychologische, toxikologische, technische und juristische Seite der Gesamtproblematik verantwortlich, sodass mit diesem Buch eine Gesamtschau entsteht, die praktische Synergieeffekte im fachlichen Verständnis ebenso erhoffen lässt wie eine qualitativ verbesserte Arbeit mit effzienteren Arbeitsergebnissen.Die Neuauflage berücksichtigt neben den aktuellen Rechtsänderungen im StVG und in der FeV auch die streitig geführte Fachdiskussion um die Auslegung der neuen Tatbestände.

For decades, Mendelian inheritance - the idea of single genes causing specific diseases - was the cornerstone of genetics. However, Genome-Wide Association Studies (GWAS) have revealed a more intricate story. This article delves into the world of GWAS and how they are revolutionizing our understanding of disease genes.We'll explore how GWAS analyze vast amounts of genetic data to identify subtle variations associated with increased disease risk. These variations often lie in non-coding DNA, which doesn't directly code for proteins, making their impact less obvious.Understanding complex genetic architecture, where multiple genes and environment play a role, is crucial for developing better diagnostics and targeted therapies.Join us as we explore the exciting world of GWAS, unveiling the complexities of disease genes and paving the way for a future of personalized medicine.

This book addressed an in-depth comprehension of the classifications and characterizations of POPs, which have become global issues due to bioaccumulation, persistency, and toxicity. It represents the milestones of the development of pesticide application, industry, and management. Banned SC-POPs have special investigations. It discusses air-sea exchange, ocean currents, phase distribution, speciation, adsorption, desorption, and degradation as the key processes that control POP's fate. The book explores several aspects of POP chemistry that have a direct influence on their biochemical and toxicological consequences. The book illustrates the dynamic equilibriums influencing the proportion of a POP's gaseous, liquid, and solid phases. The book discussed POP migration by referring to the grasshopper effect. It also explores the impacts of climate change on emissions and the fate of POPs through a global-scale multimedia fate model. Additionally, it displays the impact of potential global change scenarios on POP bioaccumulation patterns. The book is directed at giving a deep discussion of the method's QA/QC process for POP determination and has verified the accuracy and precision of the procedures. As a distinctive point, it discusses many aspects concerning the toxicity of POPs. It reports mechanisms describing the toxicity of POPs on immune systems, carcinogenesis, endocrine, neural, and reproductive systems. The book keeps an eye on a model describing the global distribution and toxicity of PAHs. Among the exclusive points in the book is the evaluation of the recent ecological status in Egypt relative to POPs through a time-scale overview and recent case studies. It provides thematic literature related to DDC research in Africa through the WoS and Scopus databases from 1949 to 2021. The book emphasizes models for predicting the annual contribution rate of POPs as a way to raise public awareness about POPs. The greatest challenge for the book is how to motivate the audience to be aware of these hazardous materials in marine ecosystems. Moreover, this book will be of great interest to academics, professionals, practitioners, post-graduate students, and undergraduates because it gives a clear overview of POPs in the marine environment. It also provides decision-makers with a realistic perspective of the environmental file, allowing them to address environmental issues and directing stockholders to safer locations for environmental activity. From a future perspective, the regulation of pervasive POPs, with special reference to recently evaluated harmful substances (PFASs), has faced significant challenges in the wake of pressure from regulators.

This open access book reviews the trends of persistent organic pollutants (POPs) in human milk and discusses the main findings of five global surveys that were coordinated by the World Health Organization (WHO) and the United Nations Environment Programme (UNEP) from 2000 to 2019. Human milk was selected as core matrix for human exposure under the Global Monitoring Plan for effectiveness evaluation of the Stockholm Convention on Persistent Organic Pollutants. Milk from well-defined groups of mothers was collected and mixed to form a representative sample per country. Datasets collected represent the largest global human tissues survey with a harmonized protocol, carried out in a uniform format for more than two decades. Altogether 69 countries participated in these studies between 2000 and 2015, and more than 40 countries participated in the study from 2016 to 2019.Divided into 5 parts, the book offers an authoritative overview of human milk biomonitoring; collates the harmonized sampling requirements and analytical methods for the identification and quantification of contaminants in human milk; examines the results of the WHO/UNEP-coordinated exposure studies, including the identification of selected chlorinated pesticides, dioxin-like compounds, industrial chemicals like polychlorinated biphenyls (PCB) and chlorinated paraffins, polybrominated POPs and PFAS, among others; and traces geographic, temporal and cross-substance trends and correlations, and human health risks. The book finishes by providing the reader with the summary of the main findings and outlook from these studies, in which the comparison of concentrations found for the wide range of POPs listed in the Stockholm Convention allowed the identification of possible needs for actions and follow-ups in different countries/regions.This book contributes to the understanding of exposure to hazardous chemicals and pollution as addressed by the UN Sustainable Development Goals onGood Health and Well-being (SDG 3) and will appeal to environmental and analytical chemists, researchers, professionals, and policymakers interested in learning more about contaminants in human milk. Given its breadth, this book will also appeal to a broader audience interested in maternal and child health.
