This book was released on 2024-05-15 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Drug Resistance in Leishmania Parasites written by Alicia Ponte-Sucre and published by Springer Science & Business Media. This book was released on 2012-09-04 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main problems concerning therapeutic tools for the treatment of parasitic diseases, including leishmaniasis, is that some field parasites are naturally resistant to the classical drugs; additionally, current therapies may select parasites prone to be resistant to the applied drugs. These features are (at least partially) responsible for the disappointing persistence of the disease and resultant deaths worldwide. This book provides a comprehensive view of the pathology of the disease itself, and of parasitic drug resistance, its molecular basis, consequences and possible treatments. Scientists both from academic fields and from the industry involved in biomedical research and drug design, will find in this book a valuable and fundamental guide that conveys the knowledge needed to understand and to improve the success in combating this disease worldwide.

Download or read book Public Health Significance of Urban Pests written by Xavier Bonnefoy and published by World Health Organization. This book was released on 2008 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second half of the 20th century and the beginning of the 21st century witnessed important changes in ecology, climate and human behaviour that favoured the development of urban pests. Most alarmingly, urban planners now face the dramatic expansion of urban sprawl, in which city suburbs are growing into the natural habitats of ticks, rodents and other pests. Also, many city managers now erroneously assume that pest-borne diseases are relics of the past. All these changes make timely a new analysis of the direct and indirect effects of present-day urban pests on health. Such an analysis should lead to the development of strategies to manage them and reduce the risk of exposure. To this end, WHO invited international experts in various fields - pests, pest-related diseases and pest management - to provide evidence on which to base policies. These experts identified the public health risk posed by various pests and appropriate measures to prevent and control them. This book presents their conclusions and formulates policy options for all levels of decision-making to manage pests and pest-related diseases in the future. [Ed.]

Download or read book Innovation in Pharmacy Advances and Perspectives September 2018 written by Organizer Committee IPAP18 – Salamanca and published by Ediciones Universidad de Salamanca. This book was released on 2018-09-21 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the summaries of the "Innovation in Pharmacy: Advances and Perspectives" that took place in Salamanca (Spain) in September 2018. The early science of chemistry and microbiology were the source of most drugs until the revolution of genetic engineering in the mid 1970s. Then biotechnology made available novel protein agents such as interferons, blood factors and monoclonal antibodies that have changed the modern pharmacy. Over the past year, a new pharmacy of oligonucleotides has emerged from the science of gene expression such as RNA splicing and RNA interference. The ability to design therapeutic agents from genomic sequences will transform treatment for many diseases. The science that created this advance and its future promise will be discussed. Phillip Allen Sharp is an American geneticist and molecular biologist who co-discovered RNA splicing. He shared the 1993 Nobel Prize in Physiology or Medicine with Richard J. Roberts for “the discovery that genes in eukaryotes are not contiguous strings but contain introns, and that the splicing of messenger RNA to delete those introns can occur in different ways, yielding different proteins from the same DNA sequence. He works in Institute Professor Koch Institute for Integrative Cancer Research, Massachusetts Institute of Technology (MIT), Cambridge, MA, US. Este libro recoge los resúmenes de la «Innovation in Pharmacy: Advances and Perspectives» que tuvo lugar en Salamanca (España) en septiembre de 2018. La ciencia primitiva de la química y la microbiología fue la fuente de la mayoría de las drogas hasta la revolución de la ingeniería genética a mediados de la década de 1970. Luego, la biotecnología puso a disposición agentes proteínicos novedosos como interferones, factores sanguíneos y anticuerpos monoclonales que han cambiado la farmacia moderna. Durante el año pasado, surgió una nueva farmacia de oligonucleótidos a partir de la ciencia de la expresión génica, como el empalme de ARN y la interferencia de ARN. La capacidad de diseñar agentes terapéuticos a partir de secuencias genómicas transformará el tratamiento de muchas enfermedades. La ciencia que creó este avance y su promesa futura será discutida. Phillip Allen Sharp es un genetista y biólogo molecular estadounidense que co-descubrió el empalme de ARN. Compartió el Premio Nobel de 1993 en Fisiología o Medicina con Richard J. Roberts por "el descubrimiento de que los genes en eucariotas no son cadenas contiguas, sino que contienen intrones, y que el empalme del ARN mensajero para eliminar esos intrones puede ocurrir de diferentes maneras, produciendo diferentes proteínas de la misma secuencia de ADN.
