The purpose of the present study was to examine visual search strategies employed by batters during a pitcher's pre-release motion. Eye movement, response time, and response accuracy were measured and analyzed while subjects were asked to observe images of pitches thrown by a pitcher edited using spatial occlusion techniques and to press a pushbutton switch when they decided to swing the bat. The results showed that the batters gazed at the pitcher's pitching wrist, elbow, and arm during the final period. When the pitcher's pitching arm was selectively occluded, the response time was significantly delayed compared with when the pitcher's other body parts were occluded. The findings suggest the importance of strategies for acquiring visual cues for batting by watching a pitcher's pitching arm during the final period. When the pitching wrist and wrist plus elbow were selectively presented during the final period, the response time was significantly delayed compared with when the pitcher's pitching wrist plus elbow plus arm, upper body, and lower body were shown. These results indicate that experts set their visual pivot on the pitcher's elbow and predict cues of the pitching arm from the whole pitcher's motion.

Nasal administration of macromolecular drugs (peptides, nanoparticles) has a possibility to enable a drug delivery system beyond the blood brain barrier via olfactory nerve transport. Basic research on nasal drug delivery to the brain has been well studied. However, evaluation of the olfactory nerve transport function in patients with olfactory disorders has yet to be done, although such an evaluation is important in selecting candidates for clinical trials. Current olfactory function tests are useful for the analysis of olfactory thresholds in olfaction-impaired patients. However, the usefulness of using the increase in olfactory thresholds in patients as an index for evaluating olfactory nerve damage has not been confirmed because of the difficulty in directly evaluating the viability of the peripheral olfactory nerves. Nasally administered thallium-201 migrates to the olfactory bulb, as has been shown in healthy volunteers. Furthermore, transection of olfactory nerve fibers in mice significantly decreases migration of nasally administered thallium-201 to the olfactory bulb. The migration of thallium-201 to the olfactory bulb is reduced in patients with impaired olfaction due to head trauma, upper respiratory tract infections, and chronic rhinosinusitis, relative to the values in healthy volunteers. Nasally administrating thallium-201 followed by single photon emission computed tomography, X-ray computed tomography and magnetic resonance imaging might be useful in choosing candidates for clinical trials of nasal drug delivery methods to the brain.

Pollutants are emitted into the atmosphere by human activity and are later deposited partly in the hydrosphere such as in ponds and lakes. Sediments in the hydrosphere retain the environmental pollutants over a long time. Using this property of sediments, many studies have revealed the historical changes in environmental pollution by sampling columnar sediment cores from the hydrosphere and estimating the deposition age of the core materials.The sources of lead can be determined using lead isotope ratios, which vary depending on the source mine. The measurement of lead isotope ratios in sediment cores is therefore very useful for identification of the historical source of environmental lead pollution.Lead in sediments is however derived from both anthropogenic sources and natural input and the lead isotope ratios of the sediment therefore consist of values averaged from the two sources. The present review describes a useful method of extracting anthropogenic lead from sediment and estimating its isotope ratios. This method can be used to estimate the isotope ratios of anthropogenic lead at the time of deposition in the environment of the sampling site. It also enables comparison of the isotope ratios of anthropogenic lead in one sediment with those in other sediments.

We compared wedged hepatic venous pressure (WHVP), splenic pulp pressure (SPP) and trans-splenic portal vein pressure (TSPVP) in healthy dogs. We found that portal blood pressure could be measured in dogs using any of these techniques. The WHVP, SPP and TSPVP were 7.8 ± 1.0, 6.2 ± 0.8 and 6.8 ± 1.2 mmHg, respectively. Measuring SPP using ultrasound is most simple and minimally invasive, and it might be useful for evaluating portal hypertension in dogs with liver diseases.

It is thought that differences in conception rate between feline epididymal sperm and ejaculate sperm occur because, unlike ejaculated sperm, caudal epididymal sperm have not been sensitized with seminal plasma (SP). In this study, we investigated whether collection of feline epididymal sperm with SP influences sperm qualities after freezing-thawing. Sperm were sensitized with SP for 10 min at room temperature. As a result, the motility of caudal epididymal sperm sensitized with SP immediately after collection was significantly lower than that of ejaculate sperm, and no difference was noted in sperm qualities after freezing-thawing. This shows that the qualities of caudal epididymal sperm cannot be improved to a level higher than those of ejaculate sperm by sensitization with SP.

The goal of this study was to prove the possibility of using silicone stents broadly used for human medicine in canine obstructive tracheal disease. A silicone stent anatomically designed for canine trachea was tested on 5 beagle dogs for 8 weeks. The stent was carefully inserted using a newly developed delivery device under fluoroscopic guidance. There were no technical difficulties in placing the stent during the procedure. Previously reported complications of airway stenting such as stent migration or granulation tissue formation did not occur in any of the cases. In addition, removal of the stent was as simple as inserting it, and complications were absent. The stent introduced in this study could possibly be applied to various canine obstructive tracheal diseases.

Simple ectopic kidney was diagnosed in three dogs by means of radiography and ultrasonography. A 2-year-old castrated male Schnauzer, a 13-year-old female Schnauzer and a 9-year-old male Jindo were referred with vomiting, hematuria and ocular discharge, respectively. In all three dogs, oval-shaped masses with soft tissue density were observed in the mid to caudal abdomen bilaterally or unilaterally, and kidney silhouettes were not identified at the proper anatomic places on abdominal radiographs. Ultrasonography confirmed the masses were malpositioned kidney. The ectopic kidneys had relatively small size, irregular shape and short ureter but showed normal function on excretory urography.

The purpose of this study was to assess the normal distribution of 18F-fluoro-2-deoxy-D-glucose (FDG) uptake of canine brain structures using a high-resolution research tomography-positron emission tomography (HRRT-PET) and 7 T-magnetic resonance imaging (MRI) fusion system. FDG-PET and T2-weighted MRI of the brain were performed on 4 healthy laboratory beagle dogs. On MRI, regions of interests (ROIs) were manually drawn over 51 intracranial structures, including nine gross structures and 42 detailed structures. Relative standard uptake value ratio (rSUV=SUV of ROI/SUV of whole brain) was calculated for each ROI. The HRRT-PET and 7 T-MRI fusion imaging system demonstrated significant differences in glucose metabolism among various intracranial structures. Among gross structures, the midbrain and the pons and medulla oblongata had the highest uptake (rSUV: 1.12 ± 0.03) and lowest uptake (rSUV: 0.90 ± 0.06) of FDG, respectively. When rSUVs were calculated on detailed regions, the caudal colliculus and the longitudinal fibers of pons had the highest (rSUV: 1.62 ± 0.05) and the lowest (rSUV: 0.63 ± 0.03) glucose metabolism, respectively. Because the high resolution of PET-MRI fusion images provided clearly identifiable metabolic activities of canine brain, the HRRT-PET and 7 T-MRI fusion imaging might be a good tool for evaluation of intracranial diseases in canines.

In this study, we conducted a survey of the cytochrome b (cytb) gene of Babesia gibsoni (B. gibsoni) isolated from clinical cases to determine the prevalence of potential atovaquone (ATV)-resistant variants. Ninety-two blood samples were collected from naturally B. gibsoni infected dogs. The cytb nucleotide sequence was determined by direct sequencing. Twelve non-synonymous amino acid substitutions were identified in cytb. The principal ATV-resistant substitution, M121I, was detected in three cases. This survey determined that potentially ATV-resistant B. gibsoni strains are present in dogs in Japan.

A seven-year-old spayed female domestic short-haired cat presented with dysuria and hematuria having been unresponsive to medical therapy. Some imaging tests such as ultrasonography, urethrocystography and computed tomography revealed the pelvic mass compressing urethra. Based on histological examination of the mass following surgical resection, the cat was diagnosed squamous cell carcinoma (SCC) derived from uterine remnant. After surgery, dysuria was resolved, but on instead, urine and fecal incontinence were observed. Then, about four months after surgery, recurrence of the mass and the symptoms was observed. Consequently, the cat was ultimately euthanized. This is the first report of SCC arising from the uterine remnant in a spayed female cat.

This paper describes a new quantification method of a product's emotional quality, which we call kansei quality, with attention paid to its diversity to support the affective design. The customer's sensitivity towards such a quality differs from person to person due to perception gaps and ambiguity. The proposed method helps the designer to grasp such diverse sensitivities of customers. In contrast to the conventional approach that aims to generalize human sensitivity using average results of sensory tests, the proposed method divides an emotional quality based on differences among the customers' sensitivity. We apply the proposed method for designing a machine sound in which the designer deals with the sound quality as a kansei quality. We carry out an impression evaluation experiment on human subjects using existing product sounds. To demonstrate the effectiveness of the method, we compare the proposed method with the conventional approach using experimental results. The comparison results show the advantages of the method, such as the avoidance of meaningless average data caused by canceling out multiple different sensitivities. Based on the proposed method, we developed a prototype system that enables the designer to evaluate the kansei qualities of created sound without conducting a sensory test.

This paper describes the design and development of softening deformable structure which enables robots to have high shape adaptability. This structure is made of a low-melting-point alloy and can be made soft and deformable through a phase change induced by heating. In the soft deformable state, it can be changed their shape by pressing themselves against objects and by using their own weight. On the other hand, in the hard state, it is enough stiff to be a part of a robot. Using this structure, we have developed two types of legged robots which have softening deformable legs. The first robot can reconstruct its original shape through reheating. The second robot has higher deformation ability and realize grasping objects, walking on a pillar and going up a ladder, which are difficult to do with its original shape, by deforming the shapes of the legs.
