Abstract
BACKGROUND The loss of structural elastin due to intrinsic and extrinsic ageing results in the skin's inability to stretch and recoil (decrease in elasticity) and manifests as loss of skin firmness and sagging. While other extracellular matrix (ECM) components such as collagen and hyaluronic acid are continually synthesized and assembled through life, elastic fibres are not. Elastic fibre assembly and functionality require fibre cross-linking, induced by the lysyl oxidase-like (LOXL) enzymes, which sharply decrease during ageing. OBJECTIVE To evaluate the enhanced elastogenic effect of a blackberry-dill extract combination, which was hypothesized to induce elastin fibre component synthesis, fibre cross-linking and reduce elastin fibre degradation. METHODS The blackberry and the dill extracts were tested separately and in combination to confirm single ingredient bioactivity and synergistic benefits. Human skin explants, dermal fibroblasts, elastase assays, ELISAs, quantitative real-time PCRs and spectrofluorometer measurements were used. Moreover, a double-blinded, placebo-controlled clinical study was carried out to assess skin elasticity using Cutometer and histologically from biopsies. RESULTS The blackberry extract induced elastin gene expression, elastin promoter activity and inhibited elastic fibre degradation by matrix metalloproteinases (MMPs) 9 and 12. The dill extract induced elastin, collagen and LOXL1 gene expression, resulting in enhanced fibre cross-linking in human skin explants. Clinically, the blackberry and dill combination treatment displayed synergistic pro-elasticity activity as compared to each ingredient alone and placebo. CONCLUSION Taken together, these results demonstrated the two multimodal plant-based extracts complemented each other in terms of bioactivity and resulted in a synergistic elastogenesis induction.

Abstract
UNLABELLED We report the long-term results of a single-stage reduction procedure for the treatment of macrodactyly. Six patients (eight cases) were included. These patients underwent a single-stage operation that included debulking with resection of the hypertrophied digital nerve and distal interphalangeal joint fusion or corrective osteotomy. Plain radiographs and functional parameters were assessed. Aesthetic improvement was achieved in all patients. The mean ratios of the lengths and circumference differences between the affected digit and the corresponding normal digit on the other hand were 1:1 and 1:1, respectively. The mean range of motion in the proximal interphalangeal joint was 76°. A sensory deficit in the lateral pulp of the distal phalangeal area was observed in three fingers. The Disabilities of the Arm, Shoulder and Hand score ranged from 0 to 9 (mean 4). The long-term results of the single-stage reduction procedure were satisfactory, as demonstrated by the excellent adjustment of the length and acceptable circumference of the affected digits. LEVEL OF EVIDENCE IV.

Abstract
A new time-saving method has been developed to produce artificial crowns without using the casting process. Plastic mixtures of gallium and other metal particles are kneaded into desired shape and then heated for hardening. By this method, the time required for hardening and producing restorative materials has been shortened greatly. In the present experiment, gallium was triturated with powdered gold, silver and copper to make binary alloy samples. The dimensional change was measured between heat treatment. After heat treatment, the test piece was examined for compressive strength, compressive shrinkage, hardness, tarnishing and difference in phase. Non-heated and heated alloy specimens (Au-Ga, Ag-Ga, Cu-Ga) expanded to form the new phase. The ability of Au-Ga samples to bear compressive strength, when heated at 300 degrees C or more (AuGa2----AuGa), became 2.6 times greater than that of non-heat-treated specimens. The compressive strength of Ag-Ga samples dropped briefly at 350 degrees C (Ag0.72Ga0.28----Ag3Ga) but increased at 450 degrees C (Ag3Ga----AgGa). The strength of Cu-Ga pieces fell by half at 475 degrees C and upward (CuGa2----unknown phase). A compression test showed that the contraction percentage of Au and Ag specimens became large as a result of heat treatment, while that of Cu alloys remained almost unchanged. The results of a hardness test (HV) were comparable to those of the compressive strength test. The Au-Ga alloys increased in hardness after high-temperature treatment. In the Ag-Ga alloys, hardness declined at 350 degrees C and increased at 450 degrees C. There was no difference in hardness between Cu specimens after heat treatment and those allowed to stand at room temperature. A tarnishing test revealed that Au-Ga samples turned slightly yellowish. In the case of Ag-Ga samples, the reflectivity Y (%) dipped slightly but discoloration was not recognizable. However, the Cu-Ga samples which were heated at temperatures of up to 280 degrees C showed a slight drop in reflectivity, but those heated at temperatures higher than 280 degrees C decreased to 50-66% in reflectivity and turned black.

Abstract
Frequency doubling of an Er:YAG laser beam is observed by using a vinylidene cyanide/vinyl acetate copolymer. The nonlinear susceptibility chi((2))(eff) is evaluated to be 5.6 x 10(-7) esu, which is 2.8 times larger than that of LiNbO(3) crystal. The dependence of the measured chi((2))(eff) on the poling process is analyzed based on a theoretical model.

Abstract
Magnetic resonance imaging (MRI) in nine children with neuroblastoma showed that MRI can effectively demonstrate primary and metastatic disease and aid in predicting tumor resectability. MRI can show changes in tumor size and intensity in response to chemotherapy or radiation therapy. Neuroblastomas have an image intensity much lower than that of liver and muscle on inversion-recovery scans. On spin-echo 500/30 scans, the tumors have a greater intensity than muscle and a similar or slightly greater intensity than liver. On spin-echo 1000/60 scans, they are always of greater intensity than liver or muscle. At this stage, the overall accuracy of MRI as compared with other imaging methods is not known.

Abstract
A new computerized apparatus was constructed to measure the resonant frequency of human ulna in vivo with high sensitivity and reproducibility. Experimental studies using aluminum bar and dried human bone revealed the importance of the ulna being positioned parallel to the radius, approximately 90 degree flexion of the elbow joint, and minimal muscle activity in order to demonstrate maximum resonant frequency of ulna. Measurement of bone resonance in monkeys in vivo and after removal of the bone in vitro showed good agreement. Product of F (maximum resonant frequency in Hz) and L (ulnar length in cm), FL, indicating the speed of propagation of sound wave through the ulna, showed a significant positive correlation with bone mineral content/bone width (BM/BW) measured by Norland-Cameron apparatus and age-bound decline in both sexes. Patients with osteomalacia and primary hyperparathyroid bone disease tended to have higher FL values than expected from BM/BW. Two-dimensional display of FL and BM/BW thus appears to be useful in distinguishing osteoporosis from osteomalacia better than the use of BM/BW alone.

Abstract
(201)TI myocardial scintigraphy was performed on 25 cases of prior myocardial infarction, and based upon phantom experiments, the infarct size was quantitatively analyzed as a defect segment percentage (DS%). DS% was compared to the left cardiac function obtained from myocardial scintigrams, RI angiocardiograms, and chest X-ray films, and the results were examined. There was a high degree of correlation between DS% and LVEF and LVEDV/ m(2) (R=-0.72, 0.84). Where DS% was less than 25%, the left ventricular function was almost normal, and where DS% was greater than 25%, deterioration could clearly be seen. There was a correlation between left ventricular volume from myocardial scintigrams and heart volume from chest X-ray films. The (201)TI uptake in the lung field from myocardial scintigrams increased as the infarct size increased, and the uptake in the upper lungs also increased.

Tc-99m-stannous pyrophosphate myocardial imaging has been one of the most effective and sensitive procedures for detection of acute myocardial infarction since Bonte et al introduced it in 1974. However, many causes of false-positive studies have also been reported since then. Presented here is an abnormal case of a patient with aortic and mitral valve replacement.
