Photodynamic therapy (PDT) is considered to be a promising method for treating various types of cancer. A homogeneous and reproducible illumination during clinical PDT plays a determinant role in preventing under- or over-treatment. The development of flexible light sources would considerably improve the homogeneity of light delivery. The integration of optical fiber into flexible structures could offer an interesting alternative. This paper aims to describe different methods proposed to develop Side Emitting Optical Fibers (SEOF), and how these SEOF can be integrated in a flexible structure to improve light illumination of the skin during PDT...

Social-historical study conducted to examine the contribution of the American Nurses of Project HOPE to the configuration of the professional identity of the first trained nurses in Alagoas, in the period of 1973-1977. The theoretical framework was the "Civilizing Process" of Norbert Elias. Primary sources were official documents and personal files of 13 respondents by oral history; the secondary sources were authors of the History of Brazil/Alagoas. Data analysis showed that the configuration of the professional identity of the first trained nurses in Alagoas was a civilizing process, with all the nuances that make up the power relations...

Tissue engineering of an anterior cruciate ligament (ACL) implant with functional enthesis requires site-directed seeding of different cell types on the same scaffold. Therefore, we studied the suitability of self-assembled three-dimensional spheroids generated by lapine ACL ligament fibroblasts for directed scaffold colonization. The spheroids were characterized in vitro during 14 days in static and 7 days in dynamic culture. Size maintenance of self-assembled spheroids, the vitality, the morphology and the expression pattern of the cells were monitored...

In July 1974, a 72 old woman had been a patient for forty years in Sainte-Anne Hospital, Ward C. As she had again a violent brawl with her neighbour patient, she revealed being a tremendous artist. She had been confined on account of dementia paralytica in the Mecca of malariotherapy, and passionately devoted herself to embroidery. Her fancy work was rather a matter for Jean Dubuffet's art through its perfect expression and deserved being known.

Embroidery techniques and patterns used for scaffold production allow the adaption of biomechanical scaffold properties. The integration of collagen into embroidered polylactide-co-caprolactone [P(LA-CL)] and polydioxanone (PDS) scaffolds could stimulate neo-tissue formation by anterior cruciate ligament (ACL) cells. Therefore, the aim of this study was to test embroidered P(LA-CL) and PDS scaffolds as hybrid scaffolds in combination with collagen hydrogel, sponge or foam for ligament tissue engineering. ACL cells were cultured on embroidered P(LA-CL) and PDS scaffolds without or with collagen supplementation...

BACKGROUND: Noise prediction is considered to be the best method for evaluating cost-preventative noise controls in industrial workrooms. One of the most important issues is the development of accurate models for analysis of the complex relationships among acoustic features affecting noise level in workrooms. In this study, advanced fuzzy approaches were employed to develop relatively accurate models for predicting noise in noisy industrial workrooms. METHODS: The data were collected from 60 industrial embroidery workrooms in the Khorasan Province, East of Iran...

It is highly important to analyze the acoustic properties of workrooms in order to identify best noise control measures from the standpoint of noise exposure limits. Due to the fact that sound pressure is dependent upon environments, it cannot be a suitable parameter for determining the share of workroom acoustic characteristics in producing noise pollution. This paper aims to empirically analyze noise source characteristics and acoustic properties of noisy embroidery workrooms based on special parameters. In this regard, reverberation time as the special room acoustic parameter in 30 workrooms was measured based on ISO 3382-2...

A poster-sized piece of embroidery, completed in the 1960s, hangs in the Glore Psychiatric Museum, a testament to the daily experience of a woman who rarely spoke and was diagnosed with schizophrenia. The embroidery document was analyzed by three researchers who came to agreement on themes via triangulation and constant comparison. The woman's lived experience was considered. The analysis found that although the patient was silent, she was connected in interesting ways to the environment around her. Implications for nursing care include awareness of the importance of milieu to patients, that silence should not be inferred to be detachment, and nurses should continue to develop creative ways to engage patients who may communicate in nontraditional ways...
