Introduction: It is estimated that there are nearly 40 million people with the human immunodeficiency virus (HIV) worldwide. Due to the advent of antiretroviral drugs, it has been observed increasing in obesity and metabolic rates among patients undergoing treatment. Thus, numerous surgical therapies for weight loss are proposed for continuous improvement in health of patients with HIV, being the vertical gastrectomy an option for intact intestinal transit. Objective: To evaluate the applicability of the vertical gastrectomy in patients with morbid obesity and HIV...

Bladder cancer (BC) is the second most common malignancy of the genitourinary system, characterized by the highest recurrence rate of all cancers. Treatment options are limited; thus a thorough understanding of the underlying molecular mechanisms is needed to guide the discovery of novel therapeutic targets. Profilins are actin binding proteins with attributed pleiotropic functions to cytoskeletal remodeling, cell adhesion, motility, even transcriptional regulation, not fully characterized yet. Earlier studies from our laboratory revealed that decreased tissue levels of Profilin-1 (PFN1) are correlated with BC progression to muscle invasive disease...

Visceral leishmaniasis (VL) is azooanthroponosis affecting both rural and peri-urban areas, and can also spread into urban areas. Although more than 90% of new cases are reported from six countries: Bangladesh, Brazil, Ethiopia, India, South Sudan and Sudan, VL has emerged in many countries in the world, presenting new cases in new countries of occurrence. Thus, studies concerning epidemiological aspects in different world regions are very meaningful.In this purpose, this study aimed analyze 89 cases of VL, treated between June 2006 and June 2014 at Eduardo de Menezes Hospital (HEM), a Reference Center of Infectious Diseases situated in Belo Horizonte, in Minas Gerais state, Brazil...

The impact of human immunodeficiency virus (HIV) infection on innate and adaptive immune activation occurs in the context of host factors, which serve to augment or dampen the physiologic response to the virus. Independent of HIV infection, nutritional status, particularly body composition, affects innate immune activation through a variety of conditions, including reduced mucosal barrier defenses and microbiome dysbiosis in malnutrition and the proinflammatory contribution of adipocytes and stromal vascular cells in obesity...

Cardiovascular diseases (CVDs) are the leading cause of mortality worldwide. Coronary heart disease (CHD) is the main cause of mortality in heart patients following stroke, rheumatic heart disease and myocardial infarctions. Approximately 80% of individuals succumb to CVDs, due to poor living conditions in low and middle income families and malnutrition. Infectious diseases, human immunodeficiency, tuberculosis, malaria, high blood pressure or hypertension, obesity and overweight, and nutritional disorders including smoking, excessive alcohol consumption, high salt and sugar intake, as well as other factors are responsible for CVDs and CHDs in young as well as elderly individuals...

Despite the great progress in breast cancer research and treatment, measures for efficient targeting of triple‑negative breast cancer (TNBC) are still lacking. The well‑established dependency of cancer cells on their microenvironment suggests that targeting the tumor niche might form a novel therapeutic approach. We identified the tumor‑associated macrophage (TAM) infiltration in breast cancer tissues by immunohistochemistry, and analyzed overall survival (OS). U937 co‑cultures with MDA‑MB‑231, MDA‑MB‑468 and MCF‑7, respectively, to simulate in vivo cellular interactions were assessed...

Human CD34(+) hematopoietic stem and progenitor cells (HSPCs) can reconstitute a human hemato-lymphoid system when transplanted into immunocompromised mice. While fetal liver- and cord blood-derived CD34(+) cells lead to high engraftment levels, engraftment of mobilized, adult donor-derived CD34(+) cells has remained poor. We generated so-called MSTRG and MISTRG hu-manized mice on a Rag2(-/-)Il2rg(-/-) background carrying a transgene for human SIRPα and human homologues of the cytokines macrophage-colony stimulating factor, thrombopoietin, with or without interleukin-3 and granulocyte-macrophage colony stimulating factor under murine promotors...

Docosahexaenoic acid-acylated phloridzin (PZ-DHA), a novel polyphenol fatty acid ester derivative, was synthesized through a regioselective acylation reaction with the aim of increasing the bioactivity of phloridzin (PZ) and docosahexaenoic acid (DHA). In this study, PZ-DHA's cytotoxic activity was explored using in vitro and in vivo models of mammary carcinoma. PZ-DHA was selectively cytotoxic for mammary carcinoma (MDA-MB-231, MDA-MB-468, 4T1, MCF-7 and T-47D) cells compared to non-malignant human mammary epithelial cells (HMEC and MCF-10A) and fibroblasts by MTS assay and Annexin-V-FLUOS/propidium iodide staining...

Intrauterine infection is one of the most frequent causes of miscarriage. CpG oligodeoxynucleotide (CpG ODN) can mimic intrauterine infection. CpG ODN-induced embryo-resorption was observed consistently in the NK-cell deficient non-obese diabetic (NOD) mice but not in the wild-type (WT) mice. To elucidate the molecular mechanisms of differential pregnancy outcomes, differentially expressed genes (DEGs) in the placenta and decidua basalis was revealed by RNA-Seq with CpG ODN or control ODN treatment. Common DEGs in the WT and NOD mice were enriched in antimicrobial/antibacterial humoral responses that may be activated as a primary response to bacterial infection...

Building on the initial successful optimization of a novel series of tetraindoles, a second generation of the compounds with changes in the core phenyl ring was synthesized to improve anticancer properties. 17 new compounds with different rigidity, planarity, symmetry and degree of conjugation of their core structures to 5-hydroxyindole units were synthesized. All the compounds were fully characterized and tested against breast cancer cell line (MDA-MB-231). The results revealed that the core structure is required for activity and it should be aromatic, rigid, planar, symmetrical and conjugated for optimal activity...

Here we characterize a new animal model that spontaneously develops chronic inflammation and fibrosis in multiple organs, the non-obese diabetic inflammation and fibrosis (N-IF) mouse. In the liver, the N-IF mouse displays inflammation and fibrosis particularly evident around portal tracts and central veins and accompanied with evidence of abnormal intrahepatic bile ducts. The extensive cellular infiltration consists mainly of macrophages, granulocytes, particularly eosinophils, and mast cells. This inflammatory syndrome is mediated by a transgenic population of natural killer T cells (NKT) induced in an immunodeficient NOD genetic background...

Tracking lymphocyte migration is an emerging strategy for non‑invasive nuclear imaging of allografts; however, its clinical application remains to be fully demonstrated. In the present study, the feasibility of using rapamycin‑treated 18F‑fluorodeoxyglucose (18F‑FDG)‑labeled splenocytes for the in vivo imaging of allografts was evaluated. C57BL/6 skin was heterotopically transplanted onto non‑obese diabetic/severe combined immunodeficient recipient mice. BALB/c 18F‑FDG‑labeled splenocytes with or without rapamycin pretreatment (designated as FR and FC cells, respectively) were transferred into recipient mice 30 days later...

With the rapid development of stem cell-based gene therapies against HIV, there is pressing requirement for an animal model to study the hematopoietic differentiation and immune function of the genetically modified cells. The humanized Bone-marrow/Liver/Thymus (BLT) mouse model allows for full reconstitution of a human immune system in the periphery, which includes T cells, B cells, NK cells and monocytes. The human thymic implant also allows for thymic selection of T cells in autologous thymic tissue. In addition to the study of HIV infection, the model stands as a powerful tool to study differentiation, development and functionality of cells derived from hematopoietic stem cells (HSCs)...

BACKGROUND: The Internet is an increasingly popular platform for public health interventions due to its distinct ability to communicate with, engage, and educate communities. Given the widespread use of the Internet, these interventions could be a means of equalizing access to information to address health disparities in minority populations, such as Hispanics. Hispanics are disproportionately affected by poor health outcomes, including obesity, diabetes, and human immunodeficiency virus/acquired immune deficiency syndrome...
