    Ultrastructural aspects of cranial and peripheric nerves of cronically diabetic and malnourished rats: a short biochemical panorama

    Diabetes Mellitus is one of the most common causes of neuropathies, which can be caused by molecular imbalances that impair metabolic pathways. Studies in rats showed the importance of sirtuins (SIRT), deacetylases that use NAD+ as a cofactor, which have a widespread function in metabolism, and their relation when food deprived or calorie restricted. Additionally, diabetic neuropathy presents different structural biomarkers that cause morphological alterations in fibers that can be partially treated. SIRT1 is the principal sirtuin, which acts on hypothalamus, liver, kidney, among other organs, up regulating or down regulating the expression of some genes or enzymes crucial in the process of glucose absorption

    Ebola: an international public health emergency

    The outbreak of Ebola in West Africa could become one of the worst infectious-disease-driven humanitarian crises of recent times. With more than 3000 deaths since the first case was confirmed in March 2014, the international community has recognized Ebola as a public health emergency of international concern and a clear threat to global health security. The complexity of dealing with this Ebola outbreak has highlighted the need for traditional actors, such as WHO and the CDC, to embrace the wider health and humanitarian community. The epidemic reinforces the need for nations to investment in health infrastructure and disease surveillance to keep pace with other developments in Africa. If Ebola arrives in high-income and middleincome nations, it should be contained quickly. The crisis shows the importance of sufficient levels of multilateral funding for WHO. The world needs a strong WHO, with the financing and political influence to fulfil its historic mission

    Plagiarism as another ethical issue in scientific research

    Get PDF
    The excessive demand for publications results in high plagiarism and duplicate numbers by scientists who take over existing texts into new publications. In addition to serious ethical problems, this practice hinders the generation of original material. In order to reduce the problem, softwares such as eTBLAST are being used to detect plagiarism and repeated papers. Despite the persistence of fraudsters, these tools have helped to reduce these problems; however, the ideal solution would be the basic ethical establishment principles. Therefore, plagiarism has always been a foible that could lead to fraudulent and dishonorable development of science

    Progress on Phage Display Technology: Tailoring Antibodies for Cancer Immunotherapy

    The search for innovative anti-cancer drugs remains a challenge. Over the past three decades, antibodies have emerged as an essential asset in successful cancer therapy. The major obstacle in developing anti-cancer antibodies is the need for non-immunogenic antibodies against human antigens. This unique requirement highlights a disadvantage to using traditional hybridoma technology and thus demands alternative approaches, such as humanizing murine monoclonal antibodies. To overcome these hurdles, human monoclonal antibodies can be obtained directly from Phage Display libraries, a groundbreaking tool for antibody selection. These libraries consist of genetically engineered viruses, or phages, which can exhibit antibody fragments, such as scFv or Fab on their capsid. This innovation allows the in vitro selection of novel molecules directed towards cancer antigens. As foreseen when Phage Display was first described, nowadays, several Phage Display-derived antibodies have entered clinical settings or are undergoing clinical evaluation. This comprehensive review unveils the remarkable progress in this field and the possibilities of using clever strategies for phage selection and tailoring the refinement of antibodies aimed at increasingly specific targets. Moreover, the use of selected antibodies in cutting-edge formats is discussed, such as CAR (chimeric antigen receptor) in CAR T-cell therapy or ADC (antibody drug conjugate), amplifying the spectrum of potential therapeutic avenues
