Anti-Inflammatory Activity of Limonene in the Prevention and Control of Injuries in the Respiratory System: A Systematic Review.

Introduction: The pulmonary inflammatory response results from exposure to injurious factors and is associated with oxidative stress, which intensifies the pathological reaction. In this context, limonene, a monoterpene found in citrus fruits, can be a therapeutic alternative for the treatment of this pathology, as it presents known anti-inflammatory and antioxidant actions.

Objective: The purpose of this article is to provide an overview of the anti-inflammatory activity of limonene and its capacity to prevent and control respiratory system injuries.

[Mixed drink consisting of guava (Psidium guajava. L) and forrageira palm (Opuntia fícus-indica): development and acceptability].

Nowadays, in the beverage industry, the mixture of products became an alternative to increase the nutritional value or even to develop new flavors in the formulation of mixed drinks. The objective of this work was to develop a mixed drink of forrageira palm with guava. Four formulations with different palm concentrations and soluble solids were evaluated, keeping the concentration of guava stable.

Schistosoma mansoni: Heterologous complementation of a yeast null mutant by SmRbx, a protein similar to a RING box protein involved in ubiquitination.

The SCF (Skp1-Cul1-F-box) complex is one of the several E3 ligase enzymes and it catalyzes protein ubiquitination and degradation by the 26S proteasome. Rbx1 is a member of the SCF complex in humans and HRT1 is its yeast orthologue. A cDNA encoding a Schistosoma mansoni Rbx1 homolog was cloned and functionally characterized.

Functional complementation of a yeast knockout strain by Schistosoma mansoni Rho1 GTPase in the presence of caffeine, an agent that affects mutants defective in the protein kinase C signal transduction pathway.

In a previous study, the Schistosoma mansoni Rho1 protein was able to complement Rho1 null mutant Saccharomyces cerevisiae cells at restrictive temperatures and under osmotic stress (low calcium concentration) better than the human homologue (RhoA). It is known that under osmotic stress, the S. cerevisiae Rho1 triggers two distinct pathways: activation of the membrane 1,3-beta-glucan synthase enzymatic complex and activation of the protein kinase C1 signal transduction pathway, promoting the transcription of response genes.

Cloning and molecular characterization of the Schistosoma mansoni genes RbAp48 and histone H4.

The human nuclear protein RbAp48 is a member of the tryptophan/aspartate (WD) repeat family, which binds to the retinoblastoma (Rb) protein. It also corresponds to the smallest subunit of the chromatin assembly factor and is able to bind to the helix 1 of histone H4, taking it to the DNA in replication. A cDNA homologous to the human gene RbAp48 was isolated from a Schistosoma mansoni adult worm library and named SmRbAp48.
