Eduardo Mazzaroppi Barao Pereira
Health has become a priority issue on the agenda in relation to Brazilian international technical cooperation in the last decade. This applies to Mozambique which is a strategic partner of Brazil's when one takes into consideration the volume of projects that have been undertaken between the two countries and the available resources on offer. There has been a shift in the foreign policy paradigm which has resulted in a new Brazilian foreign policy posture that promotes bilateral agreements and international cooperation...

The aim of this paper is twofold. First, it aims to investigate the increased interest in health as an important dimension of the foreign policy and diplomatic concerns together with the emergence of a new framework for regional health integration and regional health diplomacy. Second, it seeks to understand the role and practices of new regional blocs in the field of health and whether they are conducting to the emergence of new strategies for addressing health regional policies in South America. The regional policy process relates to health as a right...

The paper analyzes formulations in the area of international health at the time of the International Conference on Primary Health Care, held in Alma Ata, Kazakhstan, in 1978. It is set within the context of the broader debate on development and international cooperation throughout the 1970s. Three sets of concepts and prescriptive formulations were examined namely: the New International Economic Order (NIEO), the Dag Hammarskjöld Report (DHR) and the Basic Human Needs Approach (BHN). They were compared with the proposals in documents from the World Health Organization and in the statements from Halfdan Mahler, its director...

CONTEXT: Androgen deprivation therapy (ADT) is the backbone of treatment for advanced prostate cancer. However, castration-resistant prostate cancer (CRPC) nearly invariably develops through a range of different molecular mechanisms accompanied by progression to a more aggressive phenotype. OBJECTIVE: To understand the key molecular mechanisms leading to CRPC and the functional implications of this progression. Understanding molecular evolutionary mechanisms in CRPC is essential for the development of novel curative therapeutic approaches...

Rhabdomyosarcoma (RMS) is a soft tissue sarcoma that arises from muscle precursors affecting predominately children and young adults. It can be divided into two main classes: embryonal (eRMS) and alveolar rhabodomyosarcomas (aRMS). Despite the expression of early muscle specific genes, RMS cells fail to complete myogenesis even in differentiation conditions. We previously demonstrated that Enhancer Zeste of Homolog 2 (EZH2), the catalytic subunits of PRC2 complex, contributes to inhibit muscle differentiation in eRMS and its down-regulation causes a partial recovery of myogenesis...

There has been a dramatic increase in the emergence of antibiotic resistant bacterial strains, which has made antibiotic choices for infection control increasingly limited and more expensive. In the U.S. alone, antibiotic resistant bacteria cause at least 2 million infections and 23,000 deaths a year resulting in a $55-70 billion per year economic impact. Antibiotics are critical to the success of surgical procedures including orthopaedic prosthetic surgeries, and antibiotic resistance is occurring in nearly all bacteria that infect people, including the most common bacteria that cause orthopaedic infections, such as Staphylococcus aureus (S...

The Food and Drug Administration in the United States issued a much-awaited draft guidance on 'Multiple Endpoints in Clinical Trials' in January 2017. The draft guidance is well written and contains consistent message on the technical implementation of the principles laid out in the guidance. In this commentary, we raise a question on applying the principles to studies designed from a safety perspective. We then direct our attention to issues related to multiple co-primary endpoints. In a paper published in the Drug Information Journal in 2007, Offen et al...

Zhanlong Shen, Yingjiang Ye, Shan Wang
Total mesorectal excision (TME) is a mile-stone procedure in the history of rectal cancer surgery, but the exposure of surgical field of distal rectum is usually poor in patients with male, obese and narrow pelvis, which may lead to tumor residue and relative complications. Recently, a new technique called transanal TME (taTME) is considered to solve the above problems, but most medical centers are still in the learning curve of this procedure. Therefore, anatomical planes and landmarks of taTME for rectal cancer and prophylaxis of intraoperative complications are induced in this paper, which includes posterior plane: angle of anus and distal mesorectum and bleeding of mesorectum; rectosacral fascia and presacral bleeding; lateral and posterior-lateral plane: posterior branches of pelvic plexus and damage of anal function; anterior plane: vessel branches of neurovascular bundle and bleeding...

INTRODUCTION AND OBJECTIVES: Management of temporomandibular joint (TMJ) ankylosis is a challenging and rather daunting task owing to complex abnormal anatomy and its sequel to craniofacial structures. Various autogenous grafts and alloplastic materials have been tried with variable success for creation of a near-normal joint. In recent years, neocondyle distraction has added a new dimension to the management of TMJ ankylosis. The aim of this paper is to describe the role of neocondyle distraction in TMJ ankylosis...

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that predominately affects women. It is characterised by a broad spectrum of clinical manifestations, however, its course and organ involvement are unpredictable. Although over the last few decades an improvement in survival for SLE patients has been observed, pathogenic mechanisms underlying this disease are still unclear. Comorbidities, due to both disease and treatment, as well as multiple aspects of SLE, are under intensive investigation...

Christian William Callaghan
In light of dramatic advances in big data analytics and the application of these advances in certain scientific fields, new potentialities exist for breakthroughs in aging research. Translating these new potentialities to research outcomes for aging populations, however, remains a challenge, as underlying technologies which have enabled exponential increases in 'big data' have not yet enabled a commensurate era of 'big knowledge,' or similarly exponential increases in biomedical breakthroughs. Debates also reveal differences in the literature, with some arguing big data analytics heralds a new era associated with the 'end of theory' or which makes the scientific method obsolete, where correlation supercedes causation, whereby science can advance without theory and hypotheses testing...

Engaging recent social science work examining the truth making claims of science and biomedicine, this paper explores how biology is being localised in Brazilian cancer genetics. It draws from ethnographic fieldwork in urban regions of southern Brazil working with and alongside patients, families and practitioners in cancer genetic clinics. It examines how different sorts of 'local biologies' are articulated in the context of research, clinical practice and among implicated patient communities and the way these can 'recursively' move across different spheres and scales of social action to extend and transform the meaning of the biological...

Ion mobility coupled with mass spectrometry was proven to be an efficient way to characterize complex mixtures such as petroleum samples. However, the identification of isomeric species is difficult owing to the molecular complexity of petroleum and no availability of standard molecules. This paper proposes a new simple indicator to estimate the isomeric content of highly complex mixtures. This indicator is based on the full width at half maximum (FWHM) of the extracted ion mobility peak measured in millisecond or square angstrom that is corrected for instrumental factors such as ion diffusion...

This paper discusses the life and scientific work of José Vicente Barbosa du Bocage (1823-1907), a nineteenth-century Portuguese naturalist who carved a new place for zoological research in Portugal and built up a prestigious scientific career by securing appropriate physical and institutional spaces to the discipline. Although he was appointed professor of zoology at the Lisbon Polytechnic School, an institution mainly devoted to the preparatory training of military officers and engineers, he succeeded in creating the conditions that allowed him to develop consistent research in zoology at this institution...

In this paper, we consider a direct protein transfer process between cells in co-culture. Assuming that cells continually encounter each other, and from some hypotheses on cell-to-cell rules of transfer, we derive discrete and continuous Boltzmann-like integro-differential equations. The novelty of this model is to take into account multiple transfer rules. This new transfer model is used to fit the experimental data of cell-to-cell protein transfer in breast cancer.

Parylene C is a well-known polymer and it has been mainly employed as a protective layer for implantable electronics. In this paper, we propose a new approach to use Parylene C as a versatile template for patterning soft materials potentially applicable as scaffolds in cardiac tissue engineering (TE). Parylene C substrates were anisotropically patterned through standard lithographic process with hydrophilic channels separating raised hydrophobic strips. Ridges and grooves of the template are 10 µm width and depth ranging from 1 to 17 µm...

BACKGROUND: Systematic reviews of complex interventions can vary widely in purpose, data availability and heterogeneity, and stakeholder expectations. RATIONALE: This article addresses the uncertainty that systematic reviewers face in selecting methods for reviews of complex interventions. Specifically, it lays out parameters for systematic reviewers to consider when selecting analytic approaches that best answer the questions at hand, and suggests analytic techniques that may be appropriate in different circumstances...

Given the poor bioavailability of curcumin, its antinociceptive effects are produced after chronic intravenous administration of high doses, while poly (d,l-lactide-co-glycolide)-loaded vesicles (PLGA) can improve drug delivery. This paper investigates the antinociceptive effects of curcumin-loaded PLGA nanovesicles (PLGA-CUR) administered via intravenous (i.v.) or intrathecal (i.t.) routes at low and high doses. The following models of pain were used: formalin test, zymosan-induced hyperalgesia and sciatic nerve ligation inducing neuropathic allodynia and hyperalgesia...

In recent years, safer and more reliable biometric methods have been developed. Apart from the need for enhanced security, the media and entertainment sectors have also been applying biometrics in the emerging market of user-adaptable objects/systems to make these systems more user-friendly. However, the complexity of some state-of-the-art biometric systems (e.g., iris recognition) or their high false rejection rate (e.g., fingerprint recognition) is neither compatible with the simple hardware architecture required by reduced-size devices nor the new trend of implementing smart objects within the dynamic market of the Internet of Things (IoT)...

Social media has exploded in popularity in recent years. It is a powerful new tool for networking, collaborating, and for the communication and evolution of ideas. It has been increasingly used for business purposes and is now being embraced by physicians including pathologists. Pathology professional organizations and even peer-reviewed pathology journals are now beginning to use social media, as well. There are multiple social media platforms, including Twitter, Facebook, Instagram, LinkedIn, and others. Each platform has different audiences and different ways to share content and interact with other users...
