Therapeutic antibodies are recombinant proteins used in the treatment of cancer. There is a new generation of monoclonal antibodies with activity against cancer cells, known as antibody-drug conjugates. ⋯ After recognizing its antigen, the antibody-drug conjugate is endocytosed by the target cells, where the protein fraction is degraded into lysosomes, releasing the cytotoxic drug. This article reviews antibody-drug conjugates general characteristics and describes the clinical evidence of efficacy and safety of the first four approved by regulatory agencies in the United States and Europe.

Adipose tissue is an endocrine organ with high metabolic activity. Countless adipose tissue-secreted adipokines and lipokines, as well as peptides and lipids with biological activity have thus far been discovered. ⋯ The purpose of this review is to report on the most recent findings related to adipose tissue according to its color and its relationship with metabolic alterations associated with obesity. After a review of the specialized literature, white, brown and beige adipocyte populations were identified to be able to coexist within the same structure, and to modify global metabolic state in physiological or pathological situations.

The relationship between the social covenant, ethics and scientific research is highly important for society. Economic prosperity and better health are two of the main reasons why society supports science, without society itself being able to determine the nature of the research that is to be implemented; this is decided by Research Committees (RCs) and Research Ethics Committees (RECs). This article analyzes how the work of RCs and RECs must have a social covenant and represent the interests of society in order to promote its trust in research.

From 1990 to 2012, the Sanitary and Tropical Diseases Institute experienced the most important changes. In 1989, its name and orientation were modified to become the National Institute of Epidemiological Diagnosis and Reference. Shortly before, it had been formalized as the apex of the National Network of Public Health Laboratories and had incorporated laboratories for preventive programs such as exfoliative cytology and rabies, malaria and tuberculosis diagnosis; subsequently, it would incorporate other networks that emerged as part of the response to major epidemic outbreaks and to the new epidemiological outlook. ⋯ In 2001, the Institute started working with pathogens related to bioterrorism. By then, space restrictions of the headquarter's building were evident; in 2008, starting the construction of new facilities was decided. The Institute and its diagnostic networks constitute a milestone in Latin American public health of the 21st century.
