The enzyme Zmp1 is a zinc-peptidase having a critical role in M. tuberculosis pathogenicity. Here we describe the identification of a small set of Zmp1 inhibitors based on a novel 8-hydroxyquinoline-2-hydroxamate scaffold. Among the synthesized compounds, 1c was the most potent Zmp1 inhibitor known to date, and its binding mode was analysed both through kinetic studies and molecular modelling, identifying critical interactions of 1c with the zinc-ion and residues in the active site. Effect of 1c on intracellular Mycobacterium survival was assayed in J774 murine macrophages infected with M...

Horner syndrome is characterized by the following triad of clinical signs: miosis, ptosis and facial anhidrosis. In addition, iris heterochromia, conjunctival injection, facial erythema, congestive nasal mucosa and apparent enophthalmos secondary to the reduction of the palpebral fissure can appear. It is caused by an interruption of the sympathetic pathway that extends from the hypothalamus to the orbit. Because there is no decussation, the signs are homolateral to the lesion. Traditionally, it is classified as congenital and acquired...

OBJETIVE: The aim of this study was to estimate the prevalence of low physical activity levels and to identify related factors (sociodemographic, lifestyle and body weight status) in adolescents. METHODS: The study included 1103 students aged 14-19 years from city of São José/SC, Brazil. Physical activity was assessed using a questionnaire that classified adolescents into those who meet recommendations and those who do not meet recommendations. Independent variables were gender, age, monthly household income, maternal education, balanced diet, number of physical education classes, sleep/day, tobacco use, excessive alcohol use, screen time and weight status...

BACKGROUND: Bioelectrical impedance analysis (BIA) has commonly been used to assess the body composition of children and adolescents. BIA validation studies have found distinct correlation values with reference methods. OBJECTIVES: To assess the reproducibility, correlation and mean differences in body composition estimated by BIA and reference methods, we systematically reviewed the literature in the pediatric population. METHOD: The search for articles was conducted in March 2016 and was limited to articles published from 2005 to 2015 in the PubMed, Embase, EBSCO, Web of Science, Scopus and SciELO databases...

PURPOSE: To perform a systematic review to explore the clinical relevance of hTERT polymorphisms for breast cancer (BC). METHODS: Twenty-nine polymorphic regions were evaluated after comprehensive searching of 1236 articles, and selection of 9 publications (total of 12986 cases and 16758 controls). RESULTS: About the influence of hTERT variants in BC risk, 3 studies showed that the variant rs2736098 was associated with increasing risk. The variants rs10069690 and rs2853676 were also described as risk factors for BC...

BACKGROUND: Major Depressive Disorder (MDD) is a complex disease characterized by emotional, physical and cognitive symptoms. We explored the efficacy of vortioxetine versus placebo on outcomes of cognition, functioning and mood symptoms in working patients with depression, using paroxetine as an active reference. METHODS: Gainfully employed patients (18-65 years, N = 152) with MDD were randomized 1:1:1 to 8 weeks' double-blind, parallel treatment either with vortioxetine (10mg/day) or paroxetine (20mg/day), or with placebo...

REVIEW
Daniel G Dillon, Diego A Pizzagalli
Depressed individuals typically show poor memory for positive events, potentiated memory for negative events, and impaired recollection. These phenomena are clinically important but poorly understood. Compelling links between stress and depression suggest promising candidate mechanisms. Stress can suppress hippocampal neurogenesis, inhibit dopamine neurons, and sensitize the amygdala. We argue that these phenomena may impair pattern separation, disrupt the encoding of positive experiences, and bias retrieval toward negative events, respectively, thus recapitulating core aspects of memory disruption in depression...

This work proposes the variational determination of two-electron reduced density matrices corresponding to the ground state of N-electron systems within the doubly occupied-configuration-interaction methodology. The P, Q, and G two-index N-representability conditions have been extended to the T1 and T2 (T2') three-index ones and the resulting optimization problem has been addressed using a standard semidefinite program. We report results obtained from the doubly occupied-configuration-interaction method, from the two-index constraint variational procedure and from the two- and three-index constraint variational treatment...

Ancymidol inhibits the incorporation of cellulose into cell walls of maize cell cultures in a gibberellin-independent manner, impairing cell growth; the reduction in the cellulose content is compensated with xylans. Ancymidol is a plant growth retardant which impairs gibberellin biosynthesis. It has been reported to inhibit cellulose synthesis by tobacco cells, based on its cell-malforming effects. To ascertain the putative role of ancymidol as a cellulose biosynthesis inhibitor, we conducted a biochemical study of its effect on cell growth and cell wall metabolism in maize cultured cells...

IFNL3 is the strongest predictor of spontaneous resolution (SR) of hepatitis C virus (HCV), however, consideration of IFNL3 genotype alone is of limited clinical value for the prediction of SR or chronic HCV infection. The objective of this study was to analyze the impact of HLA-B, HLA-C and KIRs on SR, as well as their additive effects on the predictive value of the IFNL3 genotype. We conducted a retrospective study of HIV patients that included both SR and chronic HCV patients. In our study, 61.6% of patients with IFNL3 CC achieved SR, and 81...

BACKGROUND: Current meningococcal prime-boost vaccination schedules include separate vaccines for serogroups ACWY and B. An investigational combined serogroups ABCWY vaccine (MenABCWY) was developed to protect against clinically important Neisseria meningitidis serogroups. METHODS: In this phase 2, randomized, observer-blind, extension study (NCT01272180), participants aged 10-25 years received 1 booster dose of MenABCWY vaccine at 24 months (M) post-primary series of either MenABCWY (2 doses), 4CMenB (2 doses) or MenACWY-CRM vaccine (1 dose)...

trans-Aconitic acid (TAA) is an abundant constituent in the leaves of Echinodorus grandiflorus, a medicinal plant used to treat rheumatoid arthritis in Brazil. Esterification was explored as a strategy to increase lipophilicity and biopharmaceutical properties of TAA, a highly polar tricarboxylic acid. We herein report the synthesis of TAA esters via Fischer esterification with ethanol, n-butanol and n-octanol. The reaction kinetics was investigated to produce mono-, di- and tri- derivatives. Mono- and diesters of TAA were obtained as a mixture of positional isomers, whereas the triesters were recovered as pure compounds...

INTRODUCTION: The endoscopic endonasal approach has been recently proposed for cranio-vertebral junction lesions. The more common indication for this sagittal extension of the endonasal route is represented by odontoidectomy for irreducible ventral brainstem compression due to congenital or degenerative conditions. However, in an increasing number of studies its adoption for tumors involving the cranio-cervical junction has been reported. The aim of this study is to consider retrospectively our surgical series, focusing on the advantages and limits of this approach...

We studied the prevalence and genetic diversity of malaria parasites in the poorly investigated spotless starling (Sturnus unicolor) breeding in central Spain, aiming to describe the phylogenetic relationships among them and with other haemosporidians infecting the genus Sturnus. A total of 180 nestlings and 180 adult individuals from four different breeding seasons were screened for haemosporidian parasites using a nested PCR approach for the genera Plasmodium and Haemoproteus. Although the malaria prevalence ranged between years, the overall prevalence was 6...

Despite the evolution of runner performance in athletes with cerebral palsy (CP), little is known about neuromuscular parameters of sprinters from different classes, especially related to power output, muscular imbalances and asymmetry indexes in lower limbs. The aim of this study was to assess muscle power, muscular imbalance and asymmetry in sprinters with CP. Four male sprinters with CP (age, 18 to 27 years; body mass, 58.5 to 72.8 kg; height, 161.5 to 174 cm) classified as T38, T37, T36, T35 according to International Paralympic Committee functional classification, performed vertical counter movement jump and squat jump on force plate and isokinetic torque evaluations in both limbs...
