    Benchtop testing and on-body field studies of measurements of sweat loss and chloride concentration under imposed mechanical stresses and impacts demonstrate the key features of these platforms.

    Ageing is a process involving physical, social, psychological, spiritual and cultural changes. The elderly’s personal characteristics may change, and the place where they live can lead to differences in their individual life expectations. Nursing home or community dwelling, where the elderly live can affect their psychological and spiritual well-being and their search for meaning in life. This study aimed to determine mental health symptoms, spiritual well-being and meaning in life among older adults living in nursing homes and community dwellings.

    This cross-sectional study was conducted in three provinces of Turkey with the highest population of elderly people aged 60 and above. A total of 144 elderly people (71 living in nursing homes and 73 in community dwellings) participated in the study. The Descriptive Information Form, Brief Symptom Inventory (BSI), Spiritual Well-Being Scale and Meaning in Life Questionnaire were used for data collection. For the statistical analysis, the Kruskal-Wallis test, Mais very important in helping the elderly make sense of the changes they experience. Moreover these healthcare workers should undergo systematic training to help the elderly prepare for old age by making sense of preserving mental integrity and seeking meaning in their lives.The Cadmium (Cd)-polluted soils are is an increasing concern worldwide. Phytoextraction of Cd pollutants by high biomass plants, such as sweet sorghum, is considered an environmentally-friendly, cost-effective and sustainable strategy for remediating this problem. Nitrogen (N) is a macronutrient essential for plant growth, development and stress resistance. Nevertheless, how nitrate, as an important form of N, affects Cd uptake, translocation and accumulation in sweet sorghum is still unclear. In the present study, a series of nitrate levels (N1, 0.5 mm; N2, 2 mm; N3, 4 mm; N4, 8 mm and N5, 16 mm) with or without added 5 μm CdCl2 treatment in sweet sorghum was investigated hydroponically. The results indicate that Cd accumulation in the aboveground parts of sweet sorghum was enhanced by optimum nitrate supply, resulting from both increased dry weight and Cd concentration. Although root-to-shoot Cd translocation was not enhanced by increased nitrate, some Cd was transferred from cell walls to vacuoles in leaves. Intriguingly, expression levels of Cd uptake and transport genes, SbNramp1, SbNramp5 and SbHMA3, were not closely related to increased Cd as affected by nitrate supply. The expression of SbNRT1.1B in relation to nitrate transport showed an inverted ‘U’ shape with increasing nitrate levels under Cd stress, which was in agreement with trends in Cd concentration changes in aboveground tissues. Based on the aforementioned results, nitrate might regulate Cd uptake and accumulation through expression of SbNRT1.1B rather than SbNramp1, SbNramp5 or SbHMA3, the well-documented genes related to Cd uptake and transport in sweet sorghum.

    To investigate tooth ultrastructure and mutation of two patients in a family affected with osteogenesis imperfecta (OI) type IV and dentinogenesis imperfecta (DGI).

    Mutations were detected by whole exome and Sanger sequencing. The permanent second molar obtained from the proband (DGI1) and the primary first molar from his affected son (DGI2) were studied for their color, roughness, mineral density, hardness, elastic modulus, mineral content, and ultrastructure, compared to the controls.

    Two novel missense COL1A2 variants, c.752C>T (p.Ser251Phe) and c.758G>T (p.Gly253Val), were identified in both patients. The c.758G>T was predicted to be the causative mutation. Pulp cavities of DGI1 (permanent teeth) were obliterated while those of DGI2 (primary teeth) were wide. CQ211 The patients’ teeth had darker and redder colors; reduced dentin hardness; decreased, disorganized, and scattered dentinal tubules and collagen fibers; and irregular dentinoenamel junction (DEJ), compared to controls. Lacunae-like structures were present in DGI2.

    We reported the novel causative mutation, c.758G>T (p.Gly253Val), in COL1A2 for OI type IV and DGI. The DGI dentin demonstrated inferior mechanical property and ultrastructure, suggesting severe disturbances of dentin formation. These could contribute to fragility and prone to infection of DGI teeth. This study expands phenotypic and genotypic spectra of COL1A2 mutations.

The umbilical cord serum contains various biomolecules that have protective impacts on the damaged tissues. The aim of this study was to gauge the protective effect of human umbilical cord blood serum (hUCBS) on GM-induced hepatotoxicity. In this experimental study, 28 male Wistar rats, weighing 220 ± 20 g, were randomly categorized into 4 groups including control, GM (100 mg/kg), hUCBS at doses of 1 and 2% along with GM (100 mg/kg) for 10 days, intraperitoneally. Twenty-four hours after the last injection, direct blood sampling was taken from the heart to obtain blood serum and liver enzymes, inflammatory cytokines and liver tissue were examined for histology. GM causes necrosis and inflammation in liver tissue. Liver enzyme and inflammatory cytokine levels were significantly increased in the GM group. Human umbilical cord blood serum significantly decreased liver enzyme and inflammatory cytokines levels in the experimental groups compared to the GM group. GM causes liver damage such as the inflammation and necrosis in liver tissue. Treating the animals with hUCBS reduced the toxic effects of GM in the liver.
