Characterization of two family AA9 LPMOs from Aspergillus tamarii with distinct activities on xyloglucan reveals structural differences linked to cleavage specificity.

PLoS One 2020 8;15(7):e0235642. Epub 2020 Jul 8.

Faculty of Chemistry, Biotechnology and Food Science, Norwegian University of Life Sciences (NMBU), Ås, Norway.

Aspergillus tamarii grows abundantly in naturally composting waste fibers of the textile industry and has a great potential in biomass decomposition. Amongst the key (hemi)cellulose-active enzymes in the secretomes of biomass-degrading fungi are the lytic polysaccharide monooxygenases (LPMOs). By catalyzing oxidative cleavage of glycoside bonds, LPMOs promote the activity of other lignocellulose-degrading enzymes. Read More

Conditional Cash Transfer Program and Leprosy Incidence: Analysis of 12.9 Million Families From the 100 Million Brazilian Cohort.

Am J Epidemiol 2020 Jul 8. Epub 2020 Jul 8.

Centro de Integração de Dados e Conhecimentos para Saúde (Cidacs), Fundação Oswaldo Cruz, Salvador, Brazil.

Leprosy is a neglected tropical disease predominately affecting poor and marginalized populations. To test the hypothesis that poverty-alleviating policies may be associated with reduced leprosy incidence, we evaluated the association between the Brazilian Bolsa Familia conditional cash transfer Program (BFP) and new leprosy case detection using linked records from 12,949,730 families in the 100 Million Brazilian Cohort (2007-2014). After propensity score matching BFP beneficiary to non-beneficiary families, we used Mantel-Haenszel tests and Poisson regressions to estimate incidence rate ratios (IRRs) for new leprosy case detection and secondary endpoints related to operational classification and leprosy-associated disabilities at diagnosis.

Differential modulation of the contextual conditioned emotional response by CB1 and TRPV1 receptors in the ventromedial prefrontal cortex: Possible involvement of NMDA/nitric oxide-related mechanisms.

J Psychopharmacol 2020 Jul 8:269881120928201. Epub 2020 Jul 8.

Department of Pharmacology, Medical School of Ribeirão Preto, University of São Paulo, Ribeirao Preto, São Paulo, Brazil.

Background: Blockade of cannabinoid CB1 or vanilloid TRPV1 receptors in the ventromedial prefrontal cortex of rats respectively increases or decreases the conditioned emotional response during re-exposure to a context previously paired with footshocks. Although these mechanisms are unknown, they may involve local modulation of glutamatergic and nitrergic signaling.

Aim: We investigated whether these mechanisms are involved in the reported effects of CB1 and TRPV1 modulation in the ventromedial prefrontal cortex. Read More

Assessment of Gene Flow to Wild Relatives and Nutritional Composition of Sugarcane in Brazil.

Front Bioeng Biotechnol 2020 19;8:598. Epub 2020 Jun 19.

Evolution Laboratory, Department of Genetics, "Luiz de Queiroz" Agricultural College, University of São Paulo, Piracicaba, Brazil.

The commercial release of genetically modified organisms (GMO) requires a prior environmental and human/animal health risk assessment. In Brazil, the National Biotechnology Technical Commission (CTNBio) requires a survey of the area of natural occurrence of wild relatives of the GMO in the Brazilian ecosystems to evaluate the possibility of introgressive hybridization between sexually compatible species. Modern sugarcane cultivars, the focus of this study, derive from a series of hybridization and backcrossing events among species. Read More

Invasive Home Mechanical Ventilation: 10-Year Experience of a Pediatric Home Care Service.

Respir Care 2020 Jul 7. Epub 2020 Jul 7.

Faculty of Physical Education and Physical Therapy, Federal University of Uberlândia, Uberlândia, Brazil.

Background: Children dependent on invasive home mechanical ventilation (HMV) represent a growing population worldwide. The objective of this study was to assess the experience of 10 years of medical assistance given to pediatric patients on continuous invasive HMV at a Brazilian Home Care Service (HCS), specifically patient characteristics and predictors of outcome (ie, hospital readmission, death, and location of death).

Methods: Medical records for children on invasive HMV at the HCS between 2007 and 2016 were evaluated to collect the following data: age at admission to HCS, sex, principal diagnosis, length of hospital admission and home care period, number and cause of hospital readmissions, number of procedures, death and location of death.

[SBA 2020: Regional anesthesia safety recommendations update].

Rev Bras Anestesiol 2020 May 12. Epub 2020 May 12.

Hospital Geral do Estado 2 and of Hospital Roberto Santos, Salvador, BA, Brazil.

The purpose of the Brazilian Society of Anesthesiology's (SBA) Regional Anesthesia Safety Recommendations Update is to provide new guidelines based on the current relevant clinical aspects related to safety in regional anesthesia and analgesia. The goal of the present article is to provide a broad overview of the current knowledge regarding pre-procedure asepsis and antisepsis, risk factors, diagnosis and treatment of infectious complications resulting from anesthetic techniques. It also aims to shed light on the use of reprocessed materials in regional anesthesia practice to establish the effects of aseptic handling of vials and ampoules, and to show cost-effectiveness in the preparation of solutions to be administered continuously in regional blockades.
