Polygenic Profile and Magnitude Impact of Inflammatory Response in Soccer Athletes

Open journal of Genetics 2024年第3期14卷 47-76页

作者： Tane Kanope Caleb Guedes Miranda dos Santos Christiano Eduardo Veneroso Andre Fornazieiro Miller Gomes de Assis Eduardo mendonça Pimenta UFMG Soccer Science Center Program in Sport Sciences School of Physical Education Physiotherapy and Occupational Therapy Federal University of Minas Gerais Belo Horizonte MG Brazil Army Institute of Biology IBEX Rio de Janeiro Brazil Graduate Program in Physical Education Federal University of Maranho So Lus MA Brazil

The practice of soccer involves carrying-out actions of high intensity, which demand a great generation of eccentric strength, which in turn results in an increase in the inflammatory response after training practice and game matches. The study aimed to investigate, in combination and individually, the association of 28 polymorphisms with the inflammatory responses of soccer athletes. The sample consisted of 47 male under-20 soccer athletes who belong to clubs in the first division of Brazilian soccer. Blood samples were collected at Pre, and 03, 24, and 48 hours after the training session to evaluate the inflammatory responses (hematological analyzes (hemogram), creatine phosphokinase (CK), high sensitivity quantitative C-reactive protein (CRP), tumor necrosis factor-alpha, (TNFα), interleukin 6 (IL-6) and insulin-like growth factor 1 (IGF-1)). DNA was obtained through scraping of buccal cells, where a sterile swab was rubbed on the inner side of the mouth of each participant 06 times. The database was built using the TruSeq DNA PCRFree kit (Illumina®) and the Covaris equipment for shearing genomic DNA (gDNA) by ultrasound. Of the analyzed SNPs, 09 (ACTN3 rs1815739, COL5A1 rs12722, COL5A1 rs3196378, HGF rs5745697, IGF1 rs35767, IL-6 rs1800795, MMP3 rs679620, SLC30A8 rs13266634, SOX15 rs4227) were individually associated with biomarkers and 07 SNPs, (COL5A1 rs12722, COL5A1 rs3196378, COL5A1 rs1800012, HGF rs5745697, IGF1 rs35767, IL-6 rs1800795 and MMP3 rs679620) analyzed in combination, explained 16% to 40% of the variation of inflammatory responses in soccer athletes. The results suggest that the genotypic profile can be taken into account for a more individualized distribution of the training load, along with the elaboration of recovery strategies for high-level athletes between training sessions and games of high physical and physiological demand.

A comparison of the management models of protected areas between China and the southern Africa region

Forestry Studies in China 2010年第3期12卷 151-157页

作者： Claudino DA VEIGA mendonA College of Science of Nature Conservation Beijing Forestry University

A comparison of the management models of protected areas between China and the African south region allows reading and evaluating the similarities and differences in the use of management model as a management tool for protected areas and specifi- cally some positive and negative features of the management approaches in these two regions. Previous to this study it verified the designation of protected areas as increasing at a faster rate than ever before, comparatively much faster now in China than southern Africa regions. With the aim of evaluating similarities and differences in the use of management model as a management tool for pro- tected areas in China and southern Africa Region, both qualitative and quantitative data were collected. Qualitative data were mainly from policy documents, scientific articles and magazine reports, whereas quantitative （secondary data） statistical data from Interna- tional Union for Conservation of Nature Resources （IUCN） and World Database on Protected Areas （WDPA）. In view of the data sources above, the study found that in China all the protected areas are state owned whilst in southern Africa regions there are some protected areas that are privately owned; also that the models or typology of governance applied are successful for the fact that they both combine co-management or collaborative management, community-conserved areas and private protected areas that are subject to greater success and can help design planning and management than those who use exclusively government management. To this, the study concluded that the use of management model is influenced by the type of governance a country applies to its reserved areas.

Current aspects of therapeutic reduction mammaplasty for immediate early breast cancer management: An update

引用

World journal of Clinical Oncology 2014年第1期5卷 1-18页

作者： Alexandre mendona Munhoz Eduardo Montag Rolf Gemperli Division of Plastic Surgery Hospital Sírio Libanês Sao Paulo 01239-040 Brazil Breast Reconstruction Group University of Sao Paulo School of Medicine Sao Paulo 01239-040 Brazil Department of Plastic Surgery University of Sao Paulo School of Medicine Sao Paulo 01239-040 Brazil

Breast-conservation surgery(BCS) is established as a safe surgical treatment for most patients with early breast cancer. Recently, advances in oncoplastic techniques are capable of preserving the breast form and quality of life. Although most BCS defects can be managed with primary closure, the aesthetic outcome may be unpredictable. Among technical options, therapeutic reduction mammaplasty(TRM) remains a useful procedure since the BCS defect can be repaired and the preoperative appearance can be improved, resulting in more proportional breasts. As a consequence of rich breast tissue vascularization, the greater part of reduction techniques have based their planning on preserving the pedicle of the nipple-areola complex after tumor removal. Reliable circulation and improvement of a conical shape to the breast are commonly described in TRM reconstructions. With an immediate approach, the surgical process is smooth since both procedures can be carried out in one operative setting. Additionally,it permits wider excision of the tumor, with a superior mean volume of the specimen and potentially reduces the incidence of margin involvement. Regardless of the fact that there is no consensus concerning the best TRM technique, the criteria is determined by the surgeon's experience, the extent/location of glandular tissue resection and the size of the defect in relation to the size of the remaining breast. The main advantages of the technique utilized should include reproducibility, low interference with the oncological treatment and long-term results. The success of the procedure depends on patient selection, coordinated planning and careful intra-operative management.

Brazilian spotted fever and bartonellosis are zoonotic, emerging and under diagnosed diseases. Pets may be co-infected by multiple pathogens and become transmissions sources to humans. The study reports the first case of active co-infection by Brazilian spotted fever and bartonellosis based on serological evidence. The authors aim to demonstrate the importance of performing systematic syndromic investigations on nonspecific febrile syndromes, guided by the epidemiological history and considering the possibility of co-infection by zoonosis sharing the same ecological niche.
