Leishmaniases are a group of tropical diseases that affect millions of people worldwide. They are considered neglected diseases prevalent in emerging countries in Latin America, West Africa, and Southeast Asia and still occurring in Mediterranean countries. There is no human vaccine available to prevent and control the disease infection. For the last 70 years, the available chemotherapy has been constituted by first-line (pentavalent antimonials) and second-line drugs (amphotericin B, pentamidine, paramomycin, and miltefosine). Its route of administration is difficult, the treatment is long, and its efficiency varies depending on the parasite species and clinical manifestations, which results in the emergence of resistant cases. Moreover, they present high toxicity to patients, and even some less toxic formulations available, are still expensive for the poorest countries’ vulnerable populations. This often leads to abandonment and failure of treatment. The medical-scientific community is facing difficulties to overcome these issues with new suitable therapies, and the identification of new drug targets. So, it means that efforts to identify new strategies must continue.
Sterols and other isoprenoids are of great interest for their molecular structure and function in cell architecture and evolution, as well as for their importance in medicine and agriculture. Molecules’ 2019 Festschrift Special Issue in honor of the 65th birthday of Prof. W. David Nes, an internationally recognized chemical biologist and recipient of the George Schroepher medal for sterol research, focuses on recent developments in the chemistry, biosynthesis, and function of these polycyclic natural products. This volume of Molecules contains 16 leading-edge review articles and original research contributions from an international cast of scientists. This volume is grouped into three sections: (i) isoprenoid metabolome and diversity, (ii) clinical evaluation of sterol and triterpene structures and biosynthesis, and (iii) methods and synthesis of steroids and other compounds. The volume will be a valuable reference tool for those who study medicinal chemistry, protein chemistry, and biochemistry of isoprenoid lipids.

This book presents the most relevant articles selected from the annals of the symposium. In the last few years, Brazilian Geomorphology has experienced a series of epistemological and methodological innovations expressed by the incorporation of the complexity paradigm, by the progressive break with the climate paradigm, by the emergency role of new theories, and by the advances in methodological fields favored by the adherence to geochronological techniques and in function of the increasingly widespread use of geotechnologies. Furthermore, the Anthropocene/Technogene emerge claims to be more than only a temporal cuts, but as conceptions of a science engaged with social and environmental issu...
This work focuses on the experience of a Brazilian cassava starch agro-industry in developing its technological capabilities since 1917, when it was first established. Its main purpose is to explore how the process of technological progress which occurred along with that industrialization, especially regarding the starch industry, has been determined by the following variables: I) the pattern of capital accumulation, II) the capability of the related technical base to both the promotion or absorption of technological changes, and III) firms' strategies towards innovation.
Recent decades of neoliberal rule have seen authoritarian turns in many governments, and these decades have also been marked by increasing violence against women. The systematic killing of women in Ciudad Juárez, Mexico, has given way to a violent surge that is worldwide in its scope, concentrated in places where the state’s traditional, sovereign functions have broken down. Femicide is no longer just an intimate event: it has become anonymous and systematic, a crime of power. An intensified form of capitalism, the product of a colonial modernity that is still with us, now fuels new wars on women, which destroy society while targeting women’s bodies. Understanding this new, violent turn within patriarchy—which Rita Segato considers the primal form of human domination—means moving patriarchy from the margins to the center of our social analysis. According to Segato, it is only by revitalizing community and repoliticizing domestic space that we can redirect history towards a different destiny. At stake is nothing less than the future of humanity.
Organizadores: Daniel de Mello Ferraz, Ana Paula Martinez Duboc We don’t know what the future holds among so much polarization, hybrid wars, movements to disassemble public education, but the role of a teacher educator who is engaged and aware of its representation in the society cannot be denied and vanished. On the contrary, a teacher educator in the complexity of his/her role will inevitably be reference of resistance: creating discursive and theoretical opportunities, legitimizing knowledge other than those which comes top down. Certainly, this book will trigger other similar projects and contribute meaningfully to critical teacher education (Fabrício Ono).

The book brings to light the most recent findings on the biogeography, biodiversity, host plant induction and natural history of gall inducing insects in the Neotropical region. We attempt to summarize the work done so far in the region, promote several syntheses on many aspects such as host induction, host specialization, distribution among the several vegetation types and zones, the origin of super hosts and the mechanisms leading to geographical patterns in their distribution. Furthermore, the book constructs new perspectives for deeper understanding of galling insect evolutionary ecology and biogeopgraphy in the region.
