Quality Of Life In Patients With Parkinson's Disease And Their Caregivers' Stress Levels

Introduction. The quality of life in patients with Parkinson's disease (PD) is related to the disease level, which also indicates the caregiver's quality of life. Methods. This study comprised 43 patients with PD (31 male) and their respective caregivers (35 female) in order to evaluate if these disease symptoms may change their quality of life. Results. There was a statistically significant correlation between quality of life and the disease level and caregiver stress. The higher the score of disease level, the worse the patients and caregivers' quality of life. Conclusion. The disease control improves the patients' quality of life and, consequently, the caregivers' quality of life.162113117Quagliato, L.B., Viana, M.A., Quagliato, E.M.A.B., Simis, S., Alterações do olfato na doença de Parkinson (2007) Arq Neuropsiq, 65 (3 A), pp. 647-652Anderson, R., Bury, M., (1988) Living with chronic illness: The experience of patients and their families, pp. 88-116. , London: Allen & UnwinJacoby, A., Backer, G.A., Smith, D.F., Dewey, M.E., Chadwick, D.W., Measuring the impact of epilepsy: The development of a novel scale (1993) Epi Res, 16, pp. 83-88Price, B., Illness cares: The chronic illness experience (1996) J Adv Nurs, 24, pp. 275-279Lima, S.S.P., Quagliato, E.M.A.B., Cagliari, L.C., Souza, E.A.P., (1997) Linguagem e isolamento social no Mal de Parkinson, 1 (2), pp. 5-13. , Rev Soc Bras FonoaudiolGray, A., McNamara, I., Aziz, T., Gregory, R., Bain, P., Wilson, J., Quality of life outcomes following surgical treatment of Parkinson's disease (2002) Mov Disord, 17 (1), pp. 68-75Silva EG, Viana MA, Quagliato EMAB.

Transcriptome analysis reveals putative genes involved in the lipid metabolism of chaulmoogra oil biosynthesis in Carpotroche brasiliensis (Raddi) A.Gray, a tropical tree species

Chaulmoogra oil is found in the seeds of Carpotroche brasiliensis (Raddi) Endl. (syn. Mayna brasiliensis Raddi), an oil tree of the Achariaceae family and native to Brazil’s Atlantic Forest biome, which is considered the fifth most important biodiversity hotspot in the world. Its main constituents are cyclopentenic fatty acids. Chaulmoogra oil has economic potential because of its use in the cosmetics industry and as a drug with anti-tumor activity. The mechanisms related to the regulation of oil biosynthesis in C. brasiliensis seeds are not fully understood, especially from a tissue-specific perspective. In this study, we applied a de novo transcriptomic approach to investigate the transcripts involved in the lipid pathways of C. brasiliensis and to identify genes involved in lipid biosynthesis. Comparative analysis of gene orthology, expression analysis and visualization of metabolic lipid networks were performed, using data obtained from high-throughput sequencing (RNAseq) of 24 libraries of vegetative and reproductive tissues of C. brasiliensis. Approximately 10.4 million paired-end reads (Phred (Q) > 20) were generated and re-assembled into 107,744 unigenes, with an average length of 340 base pairs (bp). The analysis of transcripts from different tissues identified 1131 proteins involved in lipid metabolism and transport and 13 pathways involved in lipid biosynthesis, degradation, transport, lipid bodies, and lipid constituents of membranes. This is the first transcriptome study of C. brasiliensis, providing basic information for biotechnological applications of great use for the species, which will help understand chaulmoogra oil biosynthesis

Genome sequence and effectorome of Moniliophthora perniciosa and Moniliophthora roreri subpopulations

Background: The hemibiotrophic pathogens Moniliophthora perniciosa (witches' broom disease) and Moniliophthora roreri (frosty pod rot disease) are among the most important pathogens of cacao. Moniliophthora perniciosa has a broad host range and infects a variety of meristematic tissues in cacao plants, whereas M. roreri infects only pods of Theobroma and Herrania genera. Comparative pathogenomics of these fungi is essential to understand Moniliophthora infection strategies, therefore the detection and in silico functional characterization of effector candidates are important steps to gain insight on their pathogenicity. Results: Candidate secreted effector proteins repertoire were predicted using the genomes of five representative isolates of M. perniciosa subpopulations (three from cacao and two from solanaceous hosts), and one representative isolate of M. roreri from Peru. Many putative effectors candidates were identified in M. perniciosa: 157 and 134 in cacao isolates from Bahia, Brazil; 109 in cacao isolate from Ecuador, 92 and 80 in wild solanaceous isolates from Minas Gerais (Lobeira) and Bahia (Caiçara), Brazil; respectively. Moniliophthora roreri showed the highest number of effector candidates, a total of 243. A set of eight core effectors were shared among all Moniliophthora isolates, while others were shared either between the wild solanaceous isolates or among cacao isolates. Mostly, candidate effectors of M. perniciosa were shared among the isolates, whereas in M. roreri nearly 50% were exclusive to the specie. In addition, a large number of cell wall-degrading enzymes characteristic of hemibiotrophic fungi were found. From these, we highlighted the proteins involved in cell wall modification, an enzymatic arsenal that allows the plant pathogens to inhabit environments with oxidative stress, which promotes degradation of plant compounds and facilitates infection. Conclusions: The present work reports six genomes and provides a database of the putative effectorome of Moniliophthora, a first step towards the understanding of the functional basis of fungal pathogenicity. © 2018 The Author(s).This work was done in the frame of the International Consortium in Advanced Biology (CIBA; https://www.ciba-network.org).

CUBES: a UV spectrograph for the future

In spite of the advent of extremely large telescopes in the UV/optical/NIR range, the current generation of 8-10m facilities is likely to remain competitive at ground-UV wavelengths for the foreseeable future. The Cassegrain U-Band Efficient Spectrograph (CUBES) has been designed to provide high-efficiency (>40%) observations in the near UV (305-400 nm requirement, 300-420 nm goal) at a spectral resolving power of R>20,000, although a lower-resolution, sky-limited mode of R ~ 7,000 is also planned. CUBES will offer new possibilities in many fields of astrophysics, providing access to key lines of stellar spectra: a tremendous diversity of iron-peak and heavy elements, lighter elements (in particular Beryllium) and light-element molecules (CO, CN, OH), as well as Balmer lines and the Balmer jump (particularly important for young stellar objects). The UV range is also critical in extragalactic studies: the circumgalactic medium of distant galaxies, the contribution of different types of sources to the cosmic UV background, the measurement of H2 and primordial Deuterium in a regime of relatively transparent intergalactic medium, and follow-up of explosive transients. The CUBES project completed a Phase A conceptual design in June 2021 and has now entered the Phase B dedicated to detailed design and construction. First science operations are planned for 2028. In this paper, we briefly describe the CUBES project development and goals, the main science cases, the instrument design and the project organization and management

Zooterapia amazônica: uso de gordura de sucuri ( Eunectes murinus ) como cicatrizante natural

Zootherapy (the use of the therapeutic potential of animals) is at least 6,000 years old, and has been kept active throughout generations until modern days. Animal fat is commonly used in the zootherapeutic folk medicine from South America, specially the green anaconda's fat, which is widely promoted as a natural medicine to treat wounds, even though there is no scientific evidence showing its efficacy. In this study we compared the total healing time and the proportional daily reduction of dorsal epithelial incisions in adult male Wistar rats treated with nitrofural (a commercial cicatrizing ointment) and with anaconda fat. We applied the treatments every two days and measured the incision diameter daily, during ten consecutive days. Differences among the groups in the total healing time and in the proportional daily reduction of the incision consistently showed that the fat-based treatment resulted in a faster healing process compared to the commercial ointment tested. The literature suggests that the efficacy of animal fat on healing may be primarily related to the presence of fatty acids, which have been widely demonstrated to be important for biochemical reactions involved in healing processes. Our findings are widely socially relevant, considering that traditional Amazonian communities that use anaconda fat in folk medicine do not have easy access to pharmacies and hospitals.Práticas ancestrais de zooterapia (uso das potencialidades terapêuticas da fauna) existem há pelo menos 6000 anos, e têm sido mantidas ao longo de gerações até os tempos modernos. Gordura de animais é comumente utilizada na zooterapia tradicional da América do Sul, e a gordura de serpentes sucuris é amplamente comercializada como cicatrizante natural, embora não existam evidências científicas que mostrem sua eficácia terapêutica. Neste estudo comparamos o tempo de cicatrização epitelial total e a redução proporcional diária de uma incisão dorsal em ratos Wistar machos adultos, entre um grupo controle, um grupo tratado com nitrofural (uma pomada cicatrizante comercial) e um grupo tratado com gordura de sucuri. Nós aplicamos os tratamentos a cada dois dias e medimos o diâmetro da incisão diariamente por dez dias consecutivos. Diferenças entre os grupos no tempo de cicatrização total e na redução proporcional diária da incisão consistentemente mostraram que gordura de sucuri teve ação cicatrizante mais eficiente que a pomada comercial testada. A literatura sugere que a eficácia de gordura animal em processos de cicatrização pode estar principalmente relacionada à presença de ácidos graxos, os quais têm sido amplamente demonstrados como importantes para reações bioquímicas envolvidas em processos de cicatrização. Os resultados têm ampla relevância social, considerando que as comunidades tradicionais amazônicas que utilizam a gordura de sucuris como zooterápico não têm acesso fácil a farmácias e hospitais
