Objective: The aim of this study was correlation proliferative activity, markers express stem cells, and lipid peroxides of undifferentiated stem cells of human adult dental follicle (DF) following culture. Methods: For this study, we used 8 samples from DF of impacted third molars to maintain culture conditions and evaluated the growth curve, cell viability, production of lipid peroxidation, cell cycle phases, and proliferative index during 25 days of culture. Results: Cells after culture showed characteristics of fibroblast-like type following 25th day of culture. The results of lipid peroxidation showed that stem cells in culture produce 13 nmoles/ml malondialdehyde at the start of culture, increasing until the 12th day and then began a decline that lasted until the 25th day. We revealed that DFSCs presented a significantly higher percentage of cells in S + G2/M phases by the 15th day of culture compared with cells at the start of culture. Cell surface markers revealed that cell lines were negative for HLA-DR and positive for CD90, CD44, and CD105. The expression of p21 protein, involved in the regulation of the cell cycle, showed a significant increase from the 15th to 25th day of culture. Results of cell division rates show a significant increase between the 6th and 15th day of culture. Conclusions: We conclude that the culture remained stable during the 25 days of culture, presenting the markers of stem cells and markers of control, progression, and cell proliferation that there was an increased production of lipid peroxides between the 6th and 12th days;this increase is related to the increased numbers of cells that also occurs during this period. Then, there is a significantly decline in the production of lipid peroxides and the number of cells, which is accompanied by an increase in cell unviability.

Background: Accessibility enables the effective participation of disabled persons in public and private areas and the use of urban equipment and street furniture. Objective: This study aimed to analyze the physical accessibility of toilet facilities in urban and rural primary health care units. Methods: It was a quantitative descriptive study conducted in 157 Primary Health Care Units of 16 municipalities in the Baturité Massif region, Ceará, Brazil. The study took place from August 2014 to May 2015, with a checklist type form, designed from the Technical Standard 9050 of the Brazilian National Standards Organization, specifying the ideal access conditions established by law to allow mobility of persons with physical disabilities. Data were processed through the Statistical Package for the Social Sciences software and organized into tables. Results: Toilets designed for physically disabled people were accessible as the location and signs (59.9%), identified with symbols for males and females (57.3%);however, the doorway width was smaller than needed to accommodate a wheelchair (77.7%). Inside the bathroom, only the forward approach was possible (59.9%). Grab bars positioned on the side and rear walls were inadequate or nonexistent (67.6%);toilet seats (91.1%) and toilet paper dispensers (96.2%) were mostly in inaccessible heights;flush controls in appropriate height (59.2%) and activated by light pressure (58%). Sinks without pedestal (51%), but higher than recommended (80.3%) and without single handle faucets (95.6%). It was verified that the toilets of basic health units located in urban areas had better accessibility conditions compared to those in rural areas. Conclusion: Results showed that the analyzed units presented physical inaccessibility in some toilet facilities, making it difficult or even impossible the accessibility for the disabled. The inclusion of accessibility features in health services for this clientele provides equal opportunities and social i

A quantitative descriptive study aimed to evaluate the physical structure accessibility of gynecological nursing clinics and their bathrooms in basic health units for users with motor disabilities. A checklist tool/instrument was applied for analyzing 16 items in the bathroom and four in the nursing clinic. 157 basic health units were evaluated. In the nursing clinic, counters and tables (79.6%) were accessible, but stretchers (93%), seats (93.6%) and doors (87.3%) were inaccessible;moreover, 17.8% of the units examined proved totally inaccessible. In the bathroom, the items with the best evaluation were the height of the toilet flusher (47%) with operation by slight pressure (44.6%) and the wall-mounted sink (42.7%). Bathroom doors and turning area/space for wheelchairs were inaccessible. No bathroom reached full accessibility, and 31.2% were entirely inaccessible. Non-compliance was evident of the standard 9050:2004 of the Brazilian Association of Technical Standards. Raising the awareness of health and engineering professionals is recommended to learn technical accessibility standards and implement them.

Corneal stem cells and tissue engineering: Current advances and future perspectives

Major advances are currently being made in regenerative medicine for cornea. Stem cell-based therapies represent a novel strategy that may substitute conventional corneal transplantation, albeit there aremany challenges ahead given the singularities of each cellular layer of the cornea. This review recapitulates the current data on corneal epithelial stem cells, corneal stromal stem cells and corneal endothelial cell progenitors. Corneal limbal autografts containing epithelial stem cells have been transplanted in humans for more than 20 years with great successful rates, and researchers now focus on ex vivo cultures and other cell lineages to transplant to the ocular surface. A small population of cells in the corneal endothelium was recently reported to have self-renewal capacity, although they do not proliferate in vivo. Two main obstacles have hindered endothelial cell transplantation to date: culture protocols and cell delivery methods to the posterior cornea in vivo. Human corneal stromal stem cells have been identified shortly after the recognition of precursors of endothelial cells. Stromal stem cells may have the potential to provide a direct cell-based therapeutic approach when injected to corneal scars. Furthermore, they exhibit the ability to deposit organized connective tissue in vitro and may be useful in corneal stroma engineering in the future. Recent advances and future perspectives in the field are discussed.

Advances in Health Promotion for People with Disabilities and the Laws of Brazil

Brazilian laws guarantee the protection to the rights of the citizenship of people with disabilities and their participation in various social sectors which influence health promotion. One aimed at reflecting about the health promotion actions contemplated in Brazilian laws directed to people with physical, hearing and visual disabilities. Through the website of the National Secretariat for the Promotion of the Rights of People with Disabilities, one selected 14 laws whose content was articulated to the Health Promotion Charts in the process of discussion. The laws had as their main objective, the accessibility of people with disabilities to urban spaces, health, income, education, transportation and leisure, i.e. to public services that are essential for the establishment of health. It is concluded that there was a progress in the elaboration of laws that guarantee the rights and integration of this population. However, it is observed that the non-compliance of the laws makes the promotion of health impossible.
