    Notes: The onset of schooling behaviour and brain growth in larval yellowtail Seriola quinqueradiata larvae fed on Artemia enriched with oleic acid (OA), eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA) for 10 days was investigated. Larvae from the DHA groups schooled with parallel orientation while those of the EPA groups showed only aggregation. Larvae of the OA groups were dispersed. DHA and EPA groups showed significantly smaller nearest neighbour distance compared with OA groups, and DHA groups showed significantly smaller values of nearest neighbour angle compared with the other groups. The relative volume of the tectum opticus (TO) of the DHA group was significantly larger in two experiments and also the relative volume of the cerebellum (CE) of that group was significantly larger in one experiment. Dietary DHA is probably critically important for the development of the brain, particularly TO, during the larval stages, and that development of TO may be the key factor of the ontogeny of schooling behaviour.

    Notes: Using a fatigue-testing method by which a fatigue crack can be propagated in a film adhered to cover an elliptical through-hole in a base plate, annealed rolled copper films have been fatigued. The effects of rolling textures and annealing twin boundaries on fatigue crack propagation behaviour are discussed. The fatigue crack propagates in a large zigzag pattern in the TC specimen (crack perpendicular to the rolling direction), while the crack propagation path in the RC specimen (crack parallel to the rolling direction) is nearly straight. Further, the fatigue cracks propagate slower toward the perpendicular direction than toward the parallel direction. After fatigue testing, the crystallographic characteristic of rolling textures around the fatigue crack in the annealed film is analysed using the EBSD (electron backscatter diffraction) system. Because the annealing twin boundary is in the same plane as the slip of the face-centred-cubic metal, the fatigue crack tends to propagate along the slip line initiated along the annealing twin boundary.

    Management and subsequent 13-year progress of a mandibular fracture with malocclusion in a child – case report (1991)

    Notes: Under acute conditions, maxillofacial injuries may be treated without the opportunity for an assessment of occlusal irregularities, even when there are mandibular fractures, because life-threatening injuries have priority over occlusion. Consequently, mandibular fractures may result in post-trauma malocclusion and facial deformity.The case history reported is of amale patient who had been involved in a traffic accident in childhood and suffered mandibular fractures. The initial incomplete man- agement resulted in persistent deformation of the mandible, disturbance of dental occlusion and difficulty in mastication. These irregularities were corrected during childhood by non-operative orthodontic treatment.When the patient reached adulthood, some permanent teeth were malformed because the fractures had damaged some tooth germs. However, the permanent dentition in general was almost normal as a result of the corrected primary dentition. Although the alveolar deformity due to the injury remained, the mandibular base was satisfactorily remodelled.The case reported supports the view that early restoration of normal dental occlusion before the eruption of permanent teeth contributes to the establishment of good functional dental occlusion of the permanent teeth.

    Notes: The aim of this study was to make a longitudinal analysis of the forces transmitted from denture base to retainers of lower free-end saddle dentures with Aker's clasps using a newly developed transducer. The experimental apparatus consisted of two components, a metal framework and a denture base embedded with a force-detecting unit. This device was the transducer, which could detect changes in lateral and vertical forces transmitted from denture base to retainers at the same time. Forces were measured on several separate occasions from the insertion of new dentures to about 4 months afterwards. The result are summarized as follows: (i) the maximal mean value of vertical forces transmitted from denture base to retainers was decreased after 1 week of insertion of new dentures, then increased and reached a constant level (about ION) 4–6 weeks after the insertion of new dentures; (ii) there were large differences in the maximal mean value of lateral forces between subjects.

    Notes: The relationship between isotonic jaw-opening and jaw-closing muscle function was studied using a newly developed apparatus which enables load and velocity to be detected simultaneously. The following results were obtained from 17 male adults(age range 22–23 years) without any occlusal dysfunction.(i) The force-velocity relationship in jaw-opening and jaw-closing muscles was represented by a hyperbolic curve, which fitted well with Hill's equation.(ii) The theoretical maximum force obtained by extrapolation from regression was 32.55±4.98 kg for jaw opening and 35.74±4.52 kg for jaw closing.(iii) The theoretical maximum velocity obtained by extrapolation from regression was 456.70±183.27 mm s−1 for jaw opening and 372.77±141.67 mm s−1 for jaw closing.(iv) The maximum mechanical power (Pmax) calculated from the product of the force and velocity was 772.20±182.65 kg.mm s−1 for jaw opening and 708.68±128.14 kg.mm s−1 for jaw closing.(v) The Pmax exerted by individual subjects was approximately 12–34% of the maximum possible force (Fmax) calculated from the force and velocity, in both jaw opening and jaw closing.There were no statistically significant differences between jaw opening and jaw closing with regard to any isotonic muscle functions. In other words, the results of this study strongly indicated a substantial balance between isotonic jaw-opening and jaw-closing muscle function in the subjects who were investigated.

    Notes: The purpose of this study was to examine longitudinal changes of the occlusal force distribution in lower distal-extension removable partial dentures with the conus crown telescopic system. Occlusal force applied to the denture and forces transmitted to the retainers were measured on several separate occasions from the insertion of new dentures to about 3 months after. The occlusal force distribution ratio to the retainers was calculated when a load of 20N was applied to the denture.The results are summarized as follows:〈list xml:id="l1" style="custom"〉(i) The more posterior the loading point of occlusal force, the smaller was the ratio. When the occlusal force was applied to the most anterior artificial tooth, the ratio was 65-100% of the occlusal force.(ii) As the denture wearing time proceeded, the ratio was decreased. The smaller the ratio, the greater was the rate of its decrease.

    The effect of sofalcone on indomethacin-induced gastric ulcers in a Helicobacter pylori-infected gnotobiotic murine model (2000)

    Notes: Background: Sofalcone has been reported to exert anti-ulcer and gastroprotective actions, but its exact mechanism of action remains unknown. In our laboratory, we found that indomethacin-induced gastric ulcers become worse when associated with Helicobacter pylori infection. Methods: We employed the H. pylori-infected gnotobiotic murine model to examine the effect of sofalcone on indomethacin-induced gastric ulcers in the presence of H. pylori infection. In vitro experiments were also done to evaluate the effects of sofalcone on H. pylori growth, adherence of H. pylori to the MKN45 cells (a human gastric epithelial cell line), and these cells' IL-8 production in the presence of H. pylori. Results: We found that sofalcone produced a significant improvement in ulcer size as well as a substantial reduction in the number of H. pylori colonies in H. pylori-infected gnotobiotic mice. In vitro sofalcone has a significant bacteriocidal effect against H. pylori and can also significantly prevent adherence of this bacterium to MKN45 cells, thus remarkably reducing IL-8 production of these cells in response to stimulation by H. pylori. Conclusion: Our results suggest that sofalcone can improve ulcer healing by the mechanisms mentioned above.

    Notes: Summary Background  Annular erythema (AE) in Sjögren's syndrome (SS) usually develops on areas of sun-exposed skin and is exacerbated during summer. Objectives  To evaluate photosensitivity in SS and to investigate the involvement of ultraviolet (UV) radiation in the development of AE in SS. Methods  Phototesting with UVA and UVB was performed on 14 SS patients, including 10 with primary SS. Clinical and histological features as well as expression of inducible nitric oxide synthase (iNOS) in the evoked skin lesions were compared with those of lupus erythematosus (LE). Eleven SS patients had a history of photosensitive AE ( n  = 4), papules ( n  = 3) or other types ( n  = 4) of lesions on their sun-exposed skin that were induced or aggravated by sunlight exposure. Results  Phototesting induced a prolonged erythematous response ( n  = 8), infiltrated erythema (IE) ( n  = 4) and/or papules ( n  = 3) in 11 of 14 SS patients, including one with primary SS without a history of photosensitivity. Histologically, the induced IE and papules showed coat-sleeve-like or sparse perivascular infiltration of lymphocytes similar to that in primary skin lesions of AE in SS. No epidermal changes characteristic for LE were found except for partial and mild liquefaction degeneration in three cases. In contrast, two cases were indistinguishable from the papular type of polymorphic light eruption in several aspects, including their primary skin lesions and early response to a photoprovocation test. Immunohistochemistry revealed diffuse expression of iNOS throughout the epidermis, which is characteristic for LE, in the three SS patients with minimal liquefaction degeneration, while the remaining seven SS patients examined exhibited no iNOS staining or a normal expression pattern. Conclusions  Our results indicate that photosensitivity exists in certain primary SS patients, and that UV is critical to the development of AE in SS, probably through a pathological mechanism distinct from that in LE.

    Notes: This paper reviews the role of alloying elements in aluminium and alloy fabrication on performance during surface treatment and surface finishing. Such elements may be present in solid solution as fine segregates, strengthening phase and equilibrium phases. For surface treatment and finishes, which generally proceed in the presence of alumina film, knowledge of the processes proceeding at the alloy/film and film/electrolyte interfaces, and those within anodic alumina films, gives rise to the possibility of controlling features of nanoscale dimensions, for improved performance, arises. Its influence on nanotextures at treated surfaces and compositionally and morphologically modified films is explained briefly.

    Notes: Abstract Roles of the blocking layer that we named the layer which separates Cu−O2 layers more than 6Å have been studied by comparing two kinds of highT c copperoxide superconductors such as Bi(2212) and La(2126) compound. These following results have been obtained. The hole concentration decreases when Sr is substituted by La and increases when Bi is substituted by Pb in Bi(2212), and it can be optimized by these substitution. In La(2126)T c becomes up to 43K and the hole concentration (p;[Cu−O]+p) increases to 0.09 by the substitution of Ca for La and heat treatment under high oxygen partial pressure. The distance between Cu−O2 layers in both Bi(2212) and La(2126) are not changed by these substitution and heat treatment. We have found that the blocking layer has not direct roles for the maximumT c value of the material though by supplying carriers to Cu−O2 layers, it affects the actualT c value.
