1. Bimetallic Au-Pd/α-MoO3 Catalyst with High Oxygen Vacancies for Selective Oxidation of Cinnamyl Alcohol
Supported Au-Pd nanoparticles (NPs) have been extensively studied in alcohol oxidation reactions. However, few studies use reducible metal oxides as support, which can activate oxygen molecules and boost the selectivity of the reaction. In this work, Au-Pd NPs were supported on α-MoO3 and evaluated in the selective oxidation of cinnamyl alcohol without solv

4. Boosting the Photocurrent of the WO3/BiVO4 Heterojunction by Photoelectrodeposition of the Oxy-Hydroxide-Phosphates Based on Co, Fe, or Ni
Here we investigated the photoelectrodeposition of oxygen-evolving catalysts (OECs) based on oxy-hydroxides-phosphates of Co, Fe, or Ni (CoPi, FePi, and NiPi) on the WO3/BiVO4 heterojunction and their activity in water oxidation. The OECs were deposited by cycles of (i) open-circuit potential (OCP) and (ii) applying a potential positive enough to oxidize the

5. Recombinant gonadotropin therapy to improve spermatogenesis in nonobstructive azoospermic patients – A proof of concept study
ABSTRACT Purpose: Nonobstructive azoospermia (NOA) associated with primary spermatogenic failure is a common cause of male infertility usually considered untreatable; however, some reports have suggested that hormonal stimulation to boost the intra-testicular testosterone level and spermatogenesis might increase the chance of achieving pregnancy using homol

6. Effects of Hyperthyroidism on Contractility and Na+/Ca2+ Exchanger Activity in the Isolated Papillary Muscle of Rats
Abstract Background: Hyperthyroidism (Hy) is an endocrine disorder, in which the thyroid hormones markedly alter the cardiac function. Increased myocardial contractility and cardiac output, improvement in diastolic relaxation, changes in electrical activity, increments in ventricular mass, and arrhythmias have been reported. However, the influences of thyro

9. Advances in the knowledge of the natural history of aquatic plants in the Neotropics
ABSTRACT Until the mid-XX century, little awareness on the ecological services or socio-environmental problems and benefits related to aquatic plants culminated in bottlenecks on their natural history, especially for the Neotropics. In this context, Acta Botanica Brasilica (ABB) organized this special issue to promote the advancement of knowledge on this eco

10. Diffusion and adaptation of the regulatory agency model in Brazil
Resumo Este artigo examina a difusão de agências reguladoras independentes no Brasil, demonstrando de que forma a interação entre variáveis relacionadas ao contexto local e mecanismos tradicionais de difusão levaram a um expressivo processo de agencificação. Embora mecanismos top-down, bottom-up e horizontais tenham desempenhado um papel importante n

11. Neonatal sepsis with neutropenia: granulocyte-colony stimulating factor (G-CSF)
RESUMO O alvo cp1002_RS01850 de Corynebacterium pseudotuberculosis foi utilizado para construir uma vacina recombinante de subunidade e de DNA contra a linfadenite caseosa. A proteína recombinante rCP01850 foi expressa em Escherichia coli usando o vetor pAE, e a vacina de DNA foi construída com o vetor pTARGET. Camundongos BALB/c foram divididos em grupos
