Newsletter - Annals of the Brazilian Academy of SciencesISSUE 54 |
||
With great pleasure I am introducing the volume 94-2 of the Annals of the Brazilian Academy of Sciences (AABC) with a record number of articles: 70! As everyone knows, the present time has been quite hard for periodicals in Brazil and, therefore, to have this large number of papers demonstrates the indisputable commitment of the Brazilian Academy of Sciences (ABC) to the dissemination of science. Again, almost all main scientific fields covered by the AABC are represented: Health Sciences (HeSci - 14), Ecosystems (Ecosy - 10), Crop Science (CrSci - 10), Cellular and Molecular Biology (CeMoBio - 9), Biomedical Sciences (BmSci - 7), Microbiology (Mcbio - 5), Animal Science (AnSci - 4), Soil Science (SoiSci - 2), Geosciences (Geosci - 2), Engineering Sciences (EnSci - 2), Social Sciences (SocSci - 2), Forestry Science (FoSci - 1), Chemical Sciences (ChSci - 1), and Mathematical Sciences (MaSci - 1). As usual, it is very difficult to point out the highlights since more than ever, tough decisions must be made to accept manuscripts in this journal. This issue presents several papers regarding the effects of COVID-19 (HeSci), such as numbers of deaths in Brazil and influences of the pandemic in respect to other diseases, the impact in southern Brazil, risks of miscarriages, and the potential of vitamin D to cope with this viral infection. There are also several interesting papers on cancer. In the field of CeMoBio, there is an article on the effect of commercial Atrazine and a study of new molecular data of a specific anuran and its diversification in several regions of Brazil. BmSci shows contributions focusing on yellow fever in urban areas and the use of nanocrystals in healing wounds. Other interesting articles deal with the reaction of microbiological communities in areas of toxic disposals (Mcbio), fisheries resources and the patent system (Ecosy), silver nanoparticles to study invasive plant species (CrSci), and the feeding ecology of endemic frogs that live in the Atlantic Forest (AnSci). Lastly, there is an article concerning the perception of harassment in universities (SocSci) and the influence of seismic hazards on cultural heritage (Geosci). Please have a quick look at the editorial as well, which provides some discussions about the bicentennial commemoration of Brazilian independence. Again, I would like to point out that since 2000 all manuscripts published by the AABC can be downloaded free of charge at the SciELO site. Furthermore, I would like to invite you to access previous editions of the Newsletter at the ABC website. We are now inviting you to scroll through the text and click on the title of the article that interests you! Alexander W. A. Kellner |

3- Alterations in the testicular parenchyma of Foxn1+/- and Foxn1-/- adult miceFERNANDA C.R. DIAS, SÉRGIO L.P. MATTA, MICHELLE B. SOARES, ELIZABETH L. OLIVEIRA, FABIANA C.S.A. MELO, NIVALDO A. PARIZOTTO, ANGELICA O. GOMES & MARCOS L.M. GOMESNude mice carry a mutation in the Foxn1 gene and therefore are homozygous recessive animals (Foxn1-/-). This strain is commonly used in scientific studies, however its fertility rate is low. Thus, the aim of this study was to describe the reason of such alteration. After testicular analyzes we have concluded that Foxn1+/- and Foxn1-/- mice showed reduced sperm count, sperm transit, and spermatogenic yield, affecting the fertility rate of such strain. Since the number of Leydig cells, which produce testosterone, were also lower, the overall androgen production could also be affected by the lack of Foxn1 gene. Read here |

4- Gait analysis with muscular fibrosis and treatment with Alpinia zerumbet essential oil in immobilized ratsTHAISA S.C. BATISTA, AMANDA F.R. OLIVEIRA, LUANA B. SANTANA, VÍTOR NASCIMENTO, EDNA A.F. CÂNDIDO & MARCUS V.A. BATISTAThis study evaluated the use of the essential oil of Alpinia zerumbet (EOAz) in the treatment of muscle fibrosis in rats with immobilized paws, condition that affects gait functionality. The use of EOAz was effective in reversing the changes in the gait of rats caused by the immobilization process. The results showed that EOAz has the potential to be a non-invasive and low-cost alternative to assist in the treatment of post-immobilization muscles, serving as the basis for further tests in humans, as this is a very common situation in several human pathologies that require immobilization or develop muscle fibrosis Read here |

7- TiO2 Nanocrystals and Annona crassiflora Polyphenols Used Alone or Mixed Impact Differently on Wound RepairFRANCYELLE B.R. DE MOURA, BRUNO ANTONIO FERREIRA, ELUSCA HELENA MUNIZ, RINARA A. SANTOS, JOSÉ AUGUSTO L. GOMIDE, ALLISSON B. JUSTINO, ANIELLE CHRISTINE A. SILVA, NOELIO O. DANTAS, DANIELE L. RIBEIRO, FERNANDA A. ARAÚJO, FOUED S. ESPINDOLA & TATIANA CARLA TOMIOSSOWe evaluated the healing effect of three ointments: TiO2 nanocrystals (TiO2-NCs), polyphenol enriched fractions obtained from Annona crassiflora fruit peel (PFAC) and a combination of these (PFAC + TiO2-NCs). The results demonstrate that although TiO2-NCs and PFACs have a healing effect, with anti-inflammatory activity, increase in collagen deposition and accelerated wound closure, the results with PFAC + TiO2-NCs showed opposite effects, with increased wound area and intensified inflammation. We suggest that although recent studies have shown promising effects of associations of nanocompounds and natural compounds, these are not always positive, varying according to the interaction between the molecules evaluated.

9- Neuroprotection of Triptolide against Amyloid-Beta1-42-induced toxicity via the Akt/mTOR/ p70S6K-mediated Autophagy PathwayPENGJUAN XU, ZIXUAN WU, YANFEI PENG, JING GAO, FANG ZHENG, JUNZHEN TAN, JING XU & TAO WANGIn this study, we investigated the effect and potential mechanism of the triptolide on neuronal death caused by amyloid-Beta1-42 (Aβ1-42). The results indicated that triptolide treatment exhibited a cytoprotective effect against cell injury induced by Aβ1-42. Meanwhile, triptolide reduced apoptosis and enhanced cell survival by decreasing autophagosome accumulation and inducing autophagic degradation. Furthermore, our results also showed that activating the Akt/mTOR/p70S6K mechanism induced triptolide protection. In conclusion, triptolide decreased autophagosome accumulation and induces autophagic degradation in Aβ-treated PC12 cells. And these results indicated that activating the Akt/mTOR/p70S6K pathway induced the protective effect of triptolide. Read here |

10- Protective effect by low-intensity downhill running training against muscle damage and oxidative stress after high-intensity downhill running in ratsAYSEL YILDIRIM, MUAZ BELVİRANLI & NİLSEL OKUDANToday, many interventions have been developed to prevent or reduce eccentric exerciseinduced muscle damage. Low-intensity eccentric exercise training or preconditioning exercises applied before high-intensity eccentric exercise are among these recommendations. This study aimed to examine the effects of low-intensity eccentric exercise training before high-intensity eccentric exercise on muscle damage markers, oxidative stress and antioxidant defense in rats. According to the findings we obtained from the study, low-intensity eccentric exercise training performed before high-intensity eccentric exercise has a protective effect against muscle damage and decreases the formation of oxidative damage by increasing antioxidant levels, especially in the vastus intermedius muscle.

CHAVES, MASSIMO LODA, ANDRÉIA BUFFON, RUY C.R. BECK & DIOGO A. PILGERCervical cancer is the fourth most common cancer in women and is associated with HPV infection. It is well known that tumor cells need a greater amount of energy and one way to obtain it is from fatty acids. FASN enzyme regulates the speed of fatty acids production in cancer cells. In this study, we demonstrate that FASN is present in greater amounts in cervical cells in more advanced stages of cancer than in normal cells and that this enzyme may be an important therapeutic target for new treatments for this cancer type.

23- Vitamin D: a potentially important secosteroid for coping with COVID-19THAYANNE S.S. ARAÚJO, COSME S. SANTOS, JULIANA K.B. SOARES & JULIANO C.R. FREITASCOVID-19 is a disease that has caused a high number of deaths in the world, and despite being controlled, it requires attention and the search for new quick and economical therapeutic strategies. In this sense, vitamin D stands out, an immunomodulator that has shown beneficial effects in decreasing the risk and severity of acute respiratory tract infections, possibly including COVID-19. Therefore, this review brings together a set of evidence on the role of vitamin D against viral infections with an emphasis on COVID-19, in addition to highlighting its general characteristics and importance to the organism.

26- Hepatotoxicity and Mutagenicity assessment during chronic in vivo exposure to aqueous extracts from Peperomia pellucidaYU-WEN HUANG, ARIANNE JAN TUOZO & ROGER S. TANStudies on herbal medicine have exposed some toxic effects on humans. In this study, the effects of subchronic in vivo exposure to Peperomia pellucida (L.) HBK (P. pellucida) was investigated by administering two (2) concentrations (60 mg/kg and 30 mg/kg) of P. pellucida aqueous extracts to mice for nine (9) weeks. Results showed no sufficient evidence that subchronic exposure to the aqueous extracts incurred hepatotoxicity. Furthermore, higher concentrations may be mutagenic. This study suggests that with prolonged consumption, users are advised to take precautions and moderations of its use due to the possibility of potential mutagenic effects. Read here |

DA SILVA, KARINA S. UTSUNOMIYA, PEDRO LUIZ CASTRO, JOANA D’ARC M. ROCHA, JESUI V. VISENTAINER, ELIANE GASPARINO & RICARDO P. RIBEIROThe data provide important scientific information that contributes to a better understanding of fish nutrition, about the use of an ingredient in the diet as a source of nutrients in addition to better animal health. The data can benefit the aquaculture sector, especially the area of nutritional and food management, the industry of natural products (essential oils), the scientific community of interest. The data can be used to improve the formulation of fish diets, to encourage new studies seeking to identify nutraceutical foods with potential for use and to improve the information base with scientific data inherent to the area.In the next three points you may like to explain how these data could potentially make an impact on society and highlight any other additional value of these data. With the discovery of the data it is possible to offer a food (fish) with more nutritional value to society. Read here |

59- Estimating the light conversion efficiency by sugarcane: the segmented approachLARISSA P. CRUZ, EDUARDO C. MACHADO & RAFAEL V. RIBEIROThe light conversion efficiency (εc) is one of the fundamental variables defining the biomass production. The long-standing and classical method estimates a single εc value for the whole growing season. Using this approach, we estimated theoretical εc values for sugarcane from 1.91 to 2.84 g MJ-1. The segmented approach proposed herein considers the variation of εc along the crop cycle and revealed that it can be almost three times higher than the single εc value estimated by using the classical method. Such segmentation of εc allows us to capture more insightful information about the crop dynamics in a changing environment. Read here |

61- Do biofertilizers affect nodulation ability and pod production in peanut genotypes?ANA KELLY S. JULIÃO, LUCAS N. DA LUZ, MARYSSOL T. GADELHA, MATHEUS L. OLIVEIRA, MARIA V.S. SILVEIRA, SAMUEL F.A.O. CASTRO & LENIN P. BARROSPeanut is a much appreciated oilseed plant in the world. In the northeast of Brazil, it is consumed a lot at some times of the year. The present study aimed to evaluate the effect of biofertilizer doses on peanut nodulation and production components, to define the best dose and genotype. Generally, low crop productivity is caused by the absence of appropriate technological packages. We believe that easy-to-use, low-cost technological packages, such as the use of biofertilizers, are able to increase productivity and make production more profitable to the producer. Read here |
