Purpose: This scoping review identified scientific evidence on basic human needs (BHNs) in the elderly receiving palliative care. Methods: Systematic searches were conducted using six electronic databases (PubMed, CINAHL, Scopus, Lilacs, IBECS, and Web of Science). The initial search resulted in 1,227 articles, of which 104 were identified as potentially relevant. Fifty-three articles that met the inclusion criteria were identified and included in the final analysis. Results: Using the three hierarchical dimensions of the BHN model, 17 needs were organised, with five in the psychobiological dimension, 10 in the psychosocial dimension, and two in the psychospiritual dimension. These needs reflect the importance of care with dignity and relief from suffering for the elderly in palliative care. Conclusion: Recognising impaired BHNs in elderly people receiving palliative care will contribute to better care plans for the elderly, considering the multiple bio-psycho-social-spiritual dimensions of BHNs. This review points to a predominance of psychosocial needs.

Cold tolerance at germination and seedling stage is one of the most seeked traits in Southern Brazilian rice (Oryza sativa L.) cultivars, thus, the availability of improved methods for germplasm assessment is of high importance for breeding programs. The aim of this study was to validate an optimized Average Tolerance Index (ATI) for rice germplasm assessment under cold at germination and early seedling stage. A diverse panel composed by 124 rice accessions was assayed. Four genotypes with known performance under cold were used as controls (two tolerant and two sensitive). The genotypes were sown in roll papers, and evaluated at 13 °C for 28 days (cold stress) and 25 °C for seven days (control). Four traits were measured, germination percentage, coleoptile length, root length and shoot length, which were converted in terms of relative perfor‑ mance (cold/control). A PCA analysis was carried out. The ATI was calculated as a linear combination of all trait’s relative performance, weighted by the importance of each trait in explaining the genetic variability in the set, through including the PC1 vectors as trait coefcients. K means was applied for genotype classifcation. The panel showed expressive genetic variability for performance under low temperature. The ATI successfully distinguished the controls regarding their cold tolerance and allowed the formation of four classes of genotypes, sensitive, moderately sensitive, moderately tolerant and tolerant. The assessment of rice germplasm for cold tolerance at germination and seedling stage through ATI is a viable alternative for the identifcation of tolerant genotypes.
Photoacoustic imaging of occlusal incipient caries in the visible and near-infrared range

Purpose: This study aimed to demonstrate the presence of dental caries through a photoacoustic imaging system with visible and near-infrared wavelengths, highlighting the differences between the 2 spectral regions. The depth at which carious tissue could be detected was also verified. Materials and Methods: Fifteen permanent molars were selected and classified as being sound or having incipient or advanced caries by visual inspection, radiography, and optical coherence tomography analysis prior to photoacoustic scanning. A photoacoustic imaging system operating with a nanosecond pulsed laser as the light excitation source at either 532 nm or 1064 nm and an acoustic transducer at 5 MHz was developed, characterized, and used. En-face and lateral(depth) photoacoustic signals were detected. Results: The results confirmed the potential of the photoacoustic method to detect caries. At both wavelengths, photoacoustic imaging effectively detected incipient and advanced caries. The reconstructed photoacoustic images confirmed that a higher intensity of the photoacoustic signal could be observed in regions with lesions, while sound surfaces showed much less photoacoustic signal. Photoacoustic signals at depths up to 4 mm at both 532 nm and 1064 nm were measured. Conclusion: The results presented here are promising and corroborate that photoacoustic imaging can be applied as a diagnostic tool in caries research. New studies should focus on developing a clinical model of photoacoustic imaging applications in dentistry, including soft tissues. The use of inexpensive light-emitting diodes together with a miniaturized detector will make photoacoustic imaging systems more flexible, user-friendly, and technologically viable.

This study aimed at demonstrating the effects of fermentation time (24, 48, 72, 96, and 120 h) and water activity (0.943, 0.970, and 0.985) on the production of cellulolytic enzymes by solid-state fermentation of purple mombin (Spondias purpurea L.) residue using Aspergillus niger. The fermentation was carried out at 35oC and the enzyme production was measured as endoglucanase and total cellulose activities. The optimum condition for endoglucanase was water activity 0.974 and 93.8 h of fermentation, reaching a production of 3.21 U/g of residue;whereas for total cellulase it was 0.958 and 79.4 h achieving 12.1 U/g of residue. Fermentation time had a greater effect on the endoglucanase activity, while water activity had a more significant influence on the total cellulase activity. Endoglucanase had optimum activity at temperature of 50oC and pH 5.0. Although cellulase total optimum activity was also at pH 5.0, the maximum activity was at 60oC.
