DEVELOPMENT OF EQUIPMENT FOR ESTIMATING SWIMMING POWER

INTRODUCTION: In previous studies on this topic, the methods of measuring swimming power during swimming were examined. Costill et al. (1983) developed the method of evaluating swimming power by improvement of the biokinetic swim bench. It was suggested that swimming power is one of the more important components of the sprint swimming performance. However, it was difficult to apply the equipment for measuring swimming power to the swimming training, because the equipment for measuring this was complex. Therefore the purpose of this study is to develop simple equipment for estimating swimming power

We develop a multi-channel probe system and a scanning probe system for a near-infrared spectroscopy imaging. The multi-channel probe system is composed of one light source module and eight photodetector modules. To obtain a photon path from the light source to the detector using the multi-channel probe system, we utilize a phantom containing a movable absorber in a liquid light scattering medium. The scanning probe system is composed of a nearinfrared light source, a detector, and a light source indicating a position. The probe position is detected by a camera. We realize an isotropic spatial response by use of an improved probe containing two source-and-detector pairs in a cross arrangement

Selective arterial embolization with gelatin particles for refractory knee hemarthrosis

PURPOSEWe aimed to evaluate the feasibility and safety of selective arterial embolization for refractory knee hemarthrosisMATERIALS AND METHODSTranscatheter arterial embolization for refractory knee hemarthrosis was performed on five female patients (median age, 77 years; range, 71–80 years) between May 2009 and September 2012. Selective arterial embolization of the feeding artery was performed using a 2.5 F microcatheter coaxially advanced from a 5 F catheter with its tip positioned in the superficial femoral artery. One- or two-millimeter gelatin particles were used as embolic agents.RESULTSIn all patients, transarterial embolization performed successfully after arteriography showed nontumorous staining around the knee joint. The feeding arteries were the lateral superior genicular artery in all five patients, the lateral inferior genicular artery in four patients, the medial superior genicular artery in one patient, the medial inferior genicular artery in one patient, the middle genicular artery in one patient, and the descending genicular artery in one patient. In all five patients, staining was remarkably diminished around the knee joint after the embolization procedure. No complication was observed. The hemarthrosis improved after the embolization, and the postoperative course has been uneventful with no recurrence in any patient.CONCLUSIONThese results suggest that selective arterial embolization for refractory hemarthrosis of the knee is safe and useful

Full-Length Sequence of Mouse Acupuncture-Induced 1-L (Aig1l) Gene Including Its Transcriptional Start Site

We have been investigating the molecular efficacy of electroacupuncture (EA), which is one type of acupuncture therapy. In our previous molecular biological study of acupuncture, we found an EA-induced gene, named acupuncture-induced 1-L (Aig1l), in mouse skeletal muscle. The aims of this study consisted of identification of the full-length cDNA sequence of Aig1l including the transcriptional start site, determination of the tissue distribution of Aig1l and analysis of the effect of EA on Aig1l gene expression. We determined the complete cDNA sequence including the transcriptional start site via cDNA cloning with the cap site hunting method. We then analyzed the tissue distribution of Aig1l by means of northern blot analysis and real-time quantitative polymerase chain reaction. We used the semiquantitative reverse transcriptase-polymerase chain reaction to examine the effect of EA on Aig1l gene expression. Our results showed that the complete cDNA sequence of Aig1l was 6073 bp long, and the putative protein consisted of 962 amino acids. All seven tissues that we analyzed expressed the Aig1l gene. In skeletal muscle, EA induced expression of the Aig1l gene, with high expression observed after 3 hours of EA. Our findings thus suggest that the Aig1l gene may play a key role in the molecular mechanisms of EA efficacy

柔道投技の分析 : ある金メダリストのきめ技について

Objective of this paper is to compare techniques and reveal characteristics used in Ohsotogari done by world-clss Korean and a Japanese judoists in order to assist inexperienced judoists in better mastering this offensive technique. 1) The Ohsotogari technique of H. A., a worlud-class Korean judoist, was revealed to be a throw type Ohsotogari that consists of a [CHIKAMA] stance close to the opponent, a jump inward, and momentary seizure of a leg to forcefully make the opponent bend forward. 2) In comparison, the Ohsotogari technique of T. S., a Japanese judoist, was a set-up technique that starts with considerably more distance from the opponent, a large sliding step (nearly the length of a tatami mat) inward with the pivot leg, and an extension of the active leg. 3) It was found that both judoiste carried out a Ohsotogari techniqus employing the neck reflex. 4) Whether at the time of being thrust forward or at the time of the throw down, speed of the active foot used directy in the throw was found to be faster for H. A. Especially, speed of this foot when being brought down on the Y axis had a large difference of 2.819m/sec

Case report: Cerebellar swelling and hydrocephalus in familial hemophagocytic lymphohistiocytosis

Familial hemophagocytic lymphohistiocytosis (FHL) is a severe inborn error of immunity caused by a genetic defect that impairs the function of cytotoxic T and NK cells. There are only a few reported cases of FHL with diffuse swelling of the cerebellum and obstructive hydrocephalus. We report a case of FHL3 with neurological symptoms associated with cerebellar swelling and obstructive hydrocephalus. A male patient was hospitalized several times due to fever and decreased feeding, hepatosplenomegaly, and cytopenia since the first month of life. At 7 months of age, disturbance of consciousness was seen. Brain magnetic resonance imaging revealed signal intensity in the bilateral cerebellar hemispheres, diffusely increased periventricular white matter, and ventriculomegaly. Although he was treated with methylprednisolone pulse therapy, he was unresponsive to the treatment. He was then transferred to a local hospital after tracheotomy but died. Targeted clinical sequencing revealed a homozygous splice-site mutation in UNC13D. Pediatric hemophagocytic lymphohistiocytosis (HLH) includes some cases of central nervous symptom (CNS)-isolated HLH or CNS HLH preceding systemic lesions, which often do not initially meet the diagnostic criteria for FHL. Patients with FHL initiated by cerebellar symptoms may present with an atypical clinical course for HLH, leading to delayed diagnosis and poor outcomes. Despite the usefulness of a combination of a high percentage of lymphocytes in the peripheral leukocytes, a low lactate dehydrogenase level, and a high sIL-2R/ferritin ratio for identifying FHL, the diagnosis may be missed due to the absence of these results. Presymptomatic diagnosis of FHL by screening of newborns and subsequent early treatment of patients with a predicted poor prognosis may contribute to better outcomes
