INTRODUCTION: In the 1990s, Brazil adopted a public policy that allowed for universal, free access to antiretroviral therapy (ART). Since then, treatment adherence has become a new challenge for administrators of sexually transmitted disease/acquired immunodeficiency syndrome (STD/AIDS) policies. This study quantified adherence to ART and verified whether there is an association between sociodemographic variables and clinical/laboratory data in human immunodeficiency virus (HIV)-infected patients...

Tumor genetics and escape from immune surveillance concur in the poor prognosis of PDAC. In this study an experimental model was set up to verify whether SMAD4, deleted in about 55% PDAC and associated with poor prognosis, is involved in determining immunosuppression through Exosomes (Exo). Potential mechanisms and mediators underlying SMAD4-dependent immunosuppression were evaluated by studying intracellular calcium (Fluo-4), Exo-miRNAs (microarray) and Exo-proteins (SILAC). Two PDAC cell lines expressing (BxPC3-SMAD4+) or not-expressing (BxPC3) SMAD4 were used to prepare Exo-enriched conditioned media, employed in experiments with blood donors PBMCs...

Hypoxia is the basis of many myocardial conditions, and it can initiate cell death programs, among which apoptosis is well-known. Connexin 43 (Cx43), the major component of cardiomyocyte Gap Junctions, is important in cardioprotection. Cx43is involved in ischemia/reperfusion injury and ischemic preconditioning's protection in vitro; however, its role on cardiomyocyte under hypoxia is still unclear. Reports have shown that Cx43 is also located at the inner membrane of mitochondria where it has been implicated in enhanced ischemic preconditioning response...

Recent research has started to show the key role of daily food provision practices in affecting household food waste. Building on and extending these previous contributions, the objective of this paper is to investigate how individuals' everyday practices regarding food (e.g., shopping, cooking, eating, etc.) lead to food waste, and how policy makers and the food industry can implement effective strategies to influence such practices and ultimately help consumers reduce food waste. The research performs three Studies; a critical incident qualitative study (Study 1) and a quantitative, survey-based study (Study 2) to identify and examine relevant food management behaviors associated with domestic waste...

The aim of this study was to evaluate the incremental benefit of biomarkers for prediction of Alzheimer's disease dementia (ADD) in mild cognitive impairment (MCI) when added stepwise in the order of their collection in clinical routine. The model started with cognitive status characterized by the ADAS-13 score. Hippocampus volume (HV), cerebrospinal fluid (CSF) phospho-tau (pTau), and the FDG t-sum score in an AD-meta region-of-interest were compared as neurodegeneration markers. CSF-Aβ1-42 was used as amyloidosis marker...

BACKGROUND: LMTM is being developed as a treatment for AD based on inhibition of tau aggregation. OBJECTIVES: To examine the efficacy of LMTM as monotherapy in non-randomized cohort analyses as modified primary outcomes in an 18-month Phase III trial in mild AD. METHODS: Mild AD patients (n = 800) were randomly assigned to 100 mg twice a day or 4 mg twice a day. Prior to unblinding, the Statistical Analysis Plan was revised to compare the 100 mg twice a day as monotherapy subgroup (n = 79) versus 4 mg twice a day as randomized (n = 396), and 4 mg twice a day as monotherapy (n = 76) versus 4 mg twice a day as add-on therapy (n = 297), with strong control of family-wise type I error...

Leishmania is a single-celled eukaryotic parasite afflicting millions of humans worldwide, with current therapies limited to a poor selection of drugs that mostly target elements in the parasite's cell envelope. Here we determined the atomic resolution electron cryo-microscopy (cryo-EM) structure of the Leishmania ribosome in complex with paromomycin (PAR), a highly potent compound recently approved for treatment of the fatal visceral leishmaniasis (VL). The structure reveals the mechanism by which the drug induces its deleterious effects on the parasite...

We validated 2 assays for the measurement of adenosine deaminase (ADA) activity in the saliva of pigs: the Giusti-Galanti manual method (ADA-GG) and a commercial automated assay (Diazyme Laboratories; ADA-D). Intra-assay coefficients of variation (CVs) were <7 and 9%, and interassay CVs were <12 and 5%, for ADA-GG and ADA-D, respectively. Accuracy was measured by 2 methods: recovery and linearity-under-dilution. Recovery was 82.4-106.8% for ADA-GG, and 92.8-107.9% for ADA-D. Serial dilutions showed R(2) > 0...

SAGA (Spt-Ada-Gcn5-Acetyltransferase) and TFIID (transcription factor IID) have been previously shown to facilitate the PIC (pre-initiation complex) formation at the promoters of two distinct sets of genes. Here, we demonstrate that TFIID and SAGA differentially participate in stimulation of the PIC formation (and hence transcriptional initiation) at the promoter of PHO84, a gene for high affinity inorganic phosphate (Pi) transporter for crucial cellular functions, in response to nutrient signaling. We show that transcriptional initiation of PHO84 occurs predominantly in the TFIID-dependent manner in the absence of Pi in the growth medium...

Due to its ability to compensate for signals lost following therapeutic MAPK-inhibition, insulin-like growth factor type 1 receptor (IGF-1R) co-targeting is a rational approach for melanoma treatment. However IGF-1R conformational changes associated with its inhibition can preferentially activate MAPK-pathway in a kinase-independent manner, through a process known as biased signaling. We explored the impact of biased IGF-1R signaling, on response to MAPK inhibition in a panel of skin melanoma cell lines with differing MAPK and p53 mutation statuses...

The HDAC inhibitory activity of valproic acid (VPA) has led to on-going evaluation of it as an anticancer agent. The histone deacetylase (HDAC) inhibitor AN446, a prodrug of VPA, releases the acid upon metabolic degradation. AN446 is >60 fold more potent than VPA in killing cancer cells in vitro. Herein, we compare the activities of AN446, as an anticancer agent, to those of representative types from each of the four major classes of HDAC inhibitors (HDACIs): vorinostat, romidepsin, entinostat and VPA. AN446 exhibited the greatest selectivity and HDAC inhibitory activity against cancer cells...

AIMS: The tissue inhibitor of metalloproteinase TIMP3 is a stromal protein that restrains the activity of both protease and receptor in the extracellular matrix and has been found to be down-regulated in diabetic nephropathy (DN), the leading cause of end-stage renal disease in developed countries. METHODS: In order to gain deeper insights on the association of loss of TIMP3 and DN, we performed differential proteomic analysis of kidney and blood metabolic profiling of wild-type and Timp3-knockout mice before and after streptozotocin (STZ) treatment, widely used to induce insulin deficiency and hyperglycemia...

BACKGROUND: RG7667, a novel combination of two anti-cytomegalovirus (CMV) monoclonal IgG1 antibodies (MCMV5322A and MCMV3068A), was designed to block CMV entry into host cells. It was developed as a potential therapy for preventing CMV infection and disease in transplant recipients. METHODS: In a Phase 2a trial in CMV-seronegative recipients of kidney transplants from CMV-seropositive donors, RG7667 was assessed for preventing CMV infection. Patients received 4 intravenous doses of RG7667 (10 mg/kg of each antibody, n=60) or placebo (n=60) at time of transplant, and 1, 4, and 8 weeks post transplant...

Small molecules that modulate biological functions are targets of modern day drug discovery efforts. In a common discovery platform-fragment based drug discovery, two fragments are identified that bind to adjacent sites on a target, and are then linked together using different linkers to identify the linkage for optimum activity. What is not known from these studies is the effects these linkers, that typically contain C, H, and O atoms, have on the properties of the individual fragment. Herein, we investigate such effects in a bisbenzimidazole fragment whose derivatives have a wide range of therapeutic applications in nucleic acid recognition, sensing, photodynamic therapy and as cellular probes...

Sandra Garcês, Jocelyne Demengeot
Virtually all therapeutic proteins (biologics) elicit an immune response with the consequent production of anti-drug antibodies (ADA). The majority of ADA to therapeutic monoclonal antibodies (mAbs) are directed against the antigen-binding site of the therapeutic mAb, and hence are neutralizing. This nature of the ADA response explains why fully human antibodies can still be highly immunogenic. The detection of ADA is technically challenging and all assays have limitations, namely a limited capacity in detecting ADA in the presence of a drug due to immune complex (IC) formation, which may underestimate the ADA incidence...
