H-1 and K-39 spin-lattice relaxation, ionic motion and Raman processes in the proton conducting KHSeO4 single crystal
The spin-lattice relaxation rates of H-1 and K-39 nuclei in KHSeO4 crystals were studied in the temperature range 160-400 K. The spin-lattice relaxation recovery of H-1 nucleus in this crystal can be represented with a single exponential function, and the relaxation T-1(-1) curve of H-1 can be represented with the Bloembergen-Purcell-Pound (BPP) function. The relaxation process of K-39 with dominant quadrupole relaxation can be described by a linear combination of two exponential functions. T-1(-1) for the K-39 nucleus was found to have a very strong temperature dependence, T-1(-1) = beta T-7. Rapid variations in relaxation rates are associated with critical fluctuations in the electronic spin system. The T-7 temperature dependence of the Raman relaxation rate is shown here to be due to phonon-magnon coupling. (c) 2005 Elsevier Ltd. All rights reserved
Four and a half LIM protein 1C (FHL1C)
Four-and-a-half LIM domain protein 1 isoform A (FHL1A) is predominantly expressed in skeletal and cardiac muscle. Mutations in the FHL1 gene are causative for several types of hereditary myopathies including X-linked myopathy with postural muscle atrophy (XMPMA). We here studied myoblasts from XMPMA patients. We found that functional FHL1A protein is completely absent in patient myoblasts. In parallel, expression of FHL1C is either unaffected or increased. Furthermore, a decreased proliferation rate of XMPMA myoblasts compared to controls was observed but an increased number of XMPMA myoblasts was found in the G(0)/G(1) phase. Furthermore, low expression of K(v1.5), a voltage-gated potassium channel known to alter myoblast proliferation during the G(1) phase and to control repolarization of action potential, was detected. In order to substantiate a possible relation between K(v1.5) and FHL1C, a pull-down assay was performed. A physical and direct interaction of both proteins was observed in vitro. In addition, confocal microscopy revealed substantial colocalization of FHL1C and K(v1.5) within atrial cells, supporting a possible interaction between both proteins in vivo. Two-electrode voltage clamp experiments demonstrated that coexpression of K(v1.5) with FHL1C in Xenopus laevis oocytes markedly reduced K(+) currents when compared to oocytes expressing K(v1.5) only. We here present the first evidence on a biological relevance of FHL1C
Essential oil fragrances positively affect menopausal depressive and anxiety symptoms: An EEG study for mid-life women
Perimenopausal women used to suffer from psychological menopausal symptoms such as mood fluctuation, anxiety, depressive symptoms. In order to check whether fragrances alleviate these psychological menopausal symptoms, we examined the menopausal symptom-dependent brain signals.
Twenty-eight perimenopausal women (age: 43–56) participated in this study. We did EEG recording in six odor conditions. We examined the effects of essential oil fragrances including lavender (L), olibanum (O), palmarosa (P) and couple of custom mixtures named olibanum29 (O29) and palmarosa12 (P12). As a control, no odorant condition (dipropylene glycol (DPG) solvent only) was applied.
We found that these fragrances could ameliorate brain responses of severe symptoms toward brain responses of light symptoms. Under no odorant condition, we could observe different brain response depend on menopausal symptoms severity (KI score) when negative emotion was evoked. The severity of symptoms showed a significantly negative correlation with alpha power (r = −0.41) and significantly positive correlation with beta/alpha ratio (r = 0.39) which is widely used as an arousal index. These EEG characteristics showed only in psychological symptoms category: depressive symptoms, anxiety, not in physiological symptoms. On the other hands, these significant correlations were disappeared with fragrance treatments. That is, fragrance treatments sufficiently modulate alpha power and beta/alpha ratio of severe symptoms until vanishing significant correlations.
Our study showed acute fragrance effects depend on KI score using EEG analysis. It helps us to understand brain signals while fragrances alleviate psychological menopause symptoms. In addition, we could compare numerous fragrances under the same condition for industrial applications. In summary, our study may contribute to well-being life for perimenopausal women by fragrance stimulation to alleviate psychological menopause symptoms.1
aE Journal 2015/2016: aE/INTECTURE innovating architecture
The graduation studio of Architectural Engineering focuses on the integration of (new) technology in architecture. For this purpose, the name aE/ INTECTURE® was devised, which will be developed further as a brand in the coming years. Students start with a technical fascination and translate this into an architectural concept, finally being able to implement this within the environment in a responsible way. ‘If technology is the answer, what is the question?‘ Under the guidance of a team of enthusiastic (guest) lecturers, students search for the dot on the horizon that is necessary for coming up with solutions that improve the quality of the built environment and make it more sustainable. In addition, either the ‘making‘ (make) or ‘the energy and material flow’ (flow) is used and applied as a basis in different contexts.Architectural Engineerin
