Aftereffect of motion-in-depth based on binocular cues: Effects of adaptation duration, interocular correlation, and temporal correlation.

There are at least two possible binocular cues to motion-in-depth, namely disparity change over time and interocular velocity differences. There has been significant controversy about their relative contributions to the perception of motion-in-depth. In the present study, we used the technique of selective adaptation to address this question.

Reward prediction-related increases and decreases in tonic neuronal activity of the pedunculopontine tegmental nucleus.

The neuromodulators serotonin, acetylcholine, and dopamine have been proposed to play important roles in the execution of movement, control of several forms of attentional behavior, and reinforcement learning. While the response pattern of midbrain dopaminergic neurons and its specific role in reinforcement learning have been revealed, the roles of the other neuromodulators remain elusive. Reportedly, neurons in the dorsal raphe nucleus, one major source of serotonin, continually track the state of expectation of future rewards by showing a correlated response to the start of a behavioral task, reward cue presentation, and reward delivery.

Statistical method for detecting phase shifts in alpha rhythm from human electroencephalogram data.

We developed a statistical method for detecting discontinuous phase changes (phase shifts) in fluctuating alpha rhythms in the human brain from electroencephalogram (EEG) data obtained in a single trial. This method uses the state space models and the line process technique, which is a Bayesian method for detecting discontinuity in an image. By applying this method to simulated data, we were able to detect the phase and amplitude shifts in a single simulated trial.

Swine to human transmission of reassortants of pandemic (H1N1) 2009 and endemic swine influenza viruses: Abstract.

To gain insight into the possible origin of a new reassortant influenza A virus between pandemic (H1N1) 2009 and endemic swine viruses that has jumped the species barrier and caused a few infections among humans in Indiana and Pennsylvania recently, we analyzed all full genome sequences related to this virus and report its evolutionary history, but failed to determine how the virus had emerged simultaneously in two geographically distinct areas.

Fundamental wire technique and current standard strategy of percutaneous intervention for chronic total occlusion with histopathological insights.

Currently, successful treatment of chronic total occlusion (CTO) seems markedly improved, due to several new techniques and dedicated device developments. However, this improved success rate is often limited to procedures performed by skilled, highly experienced operators. To improve the overall success rate of percutaneous coronary intervention of CTO from a worldwide perspective, a deeper understanding of CTO histopathology might offer insights into the development of new techniques and procedural strategies.

A newly cloned pig dolichyl-phosphate mannosyl-transferase for preventing the transmission of porcine endogenous retrovirus to human cells.

Porcine endogenous retrovirus (PERV) is a major problem associated with successful clinical xenotransplantation. In our previous study, reducing the high mannose type of N-glycan content proved to be very effective in downregulating PERV infectivity. In this study, dolichyl-phosphate mannosyltransferase (D-P-M), an enzyme related to the early stages of N-linked sugar synthesis was studied.

Inhibitory function of adapter-related protein complex 2 alpha 1 subunit in the process of nuclear translocation of human immunodeficiency virus type 1 genome.

The transfection of human cells with siRNA against adapter-related protein complex 2 alpha 1 subunit (AP2alpha) was revealed to significantly up-regulate the replication of human immunodeficiency virus type 1 (HIV-1). This effect was confirmed by cell infection with vesicular stomatitis virus G protein-pseudotyped HIV-1 as well as CXCR4-tropic and CCR5-tropic HIV-1. Viral adsorption, viral entry and reverse transcription processes were not affected by cell transfection with siRNA against AP2alpha.

Transcriptional regulation of nephrin gene by peroxisome proliferator-activated receptor-gamma agonist: molecular mechanism of the antiproteinuric effect of pioglitazone.

The renoprotective potential of the peroxisome proliferator-activated receptor-gamma (PPAR-gamma) agonist pioglitazone was explored in an immune model of progressive nephropathy, passive Heymann nephritis (PHN), compared with that of an angiotensin II receptor antagonist, taken as standard therapy for renoprotection. PHN rats received orally vehicle, pioglitazone (10 mg/kg twice daily), or candesartan (1 mg/kg twice daily) from months 2 to 8. Pioglitazone reduced proteinuria as effectively as candesartan and limited renal functional and structural changes.

White adipose tissue and cardiovascular disease.

Adipocytes have recently been shown to secrete a variety of bioactive substances called 'adipocytokines', and have been recognized as endocrine cells. Tumour necrosis factor (TNF)-alphaalpha, plasminogen activator inhibitor-1 (PAI-1) and heparin-binding epidermal-growth-factor-like growth factor (HBEGF) are among these adipocytokines, and they contribute to the development of vascular diseases. Visfatin is a visceral fat-specific protein that may be related to the development of obesity-related diseases such as diabetes mellitus and cardiovascular disease.

Brasilicardin A. A Novel Tricyclic Metabolite with Potent Immunosuppressive Activity from Actinomycete Nocardiabrasiliensis.

A novel tricyclic metabolite, brasilicardin A (1), with potent immunosuppressive activity has been isolated from the cultured broth of the actinomycete Nocardia brasiliensis IFM 0406, and the structure including absolute stereochemistry was established on the basis of spectroscopic data, chemical means, and X-ray analysis. Brasilicardin A (1) is the first tricyclic compound consisting of an anti/syn/anti-perhydrophenanthrene skeleton with a rhamnose, an N-acetylglucosamine, and an amino acid moiety.

Intramuscular haemangioma adjacent to the bone surface with periosteal reaction. Report of three cases and review of the literature.

We present three cases of intramuscular haemangioma adjacent to bone in the lower limb. All patients had local pain during the third decade. Plain radiographs showed an irregular or hypertrophic periosteal reaction on the shaft of the fibula and an intramuscular mass adjacent to the bone with inhomogeneous high signal intensity on MRI.

IFN regulatory factor-1-mediated transcriptional activation of mouse STAT-induced STAT inhibitor-1 gene promoter by IFN-gamma.

STAT-induced STAT inhibitor-1 (SSI-1), also referred to as suppressor of cytokine signaling-1 and JAK-binding protein, is a member of a new family, the members of which are negative regulators of cytokine signals. SSI-1 is induced by various cytokines; however, the transcriptional mechanism of the SSI-1 gene is not fully understood. Here, we showed that transcription of the mouse SSI-1 gene was initiated from six adjoining sites accompanying three GC boxes and a single GC box-like element near them, but not from the TATA box or an initiator sequence.

Strabismus surgery using the intraoperative adjustable suture method under anesthesia with propofol.

Purpose: To evaluate the feasibility and efficacy of using the intraoperative adjustable suture method with anesthesia induced by intravenously administered propofol for strabismus surgery.

Methods: Seven adult patients (mean age, 29.7 +/- 18.

Pyloric motor abnormality in patients with infantile hypertrophic pyloric stenosis.

There are no published data of manometric studies of pyloric motor function in patients with infantile hypertropic pyloric stenosis (IHPS). The present study attempted to examine the characteristics of motor abnormality of the pylorus in five children with IHPS. Using a transducer-built-in manometric catheter cannulated through the pylorus under fluoroscopy, the pressure in the pyloric canal was recorded continuously over 3 h during fasting.

A new bromopyrrole alkaloid and the optical resolution of the racemate from the marine sponge homaxinella sp.

A new bromopyrrole alkaloid (1) along with (+/-)-2 and (+/-)-longamide (3) has been isolated from the Japanese marine sponge Homaxinella sp. The structures of the compounds were proposed on the basis of spectroscopic data. The optical resolution of (+/-)-2 by chiral HPLC was successful and afforded the two enantiomers, (+)-2 and (-)-2.

Development of the Simulation Model InPest for Prediction of the Indoor Behavior of Pesticides.

The objective was to develop a computer software package (to be registered as InPest) that runs under Microsoft Excel on a personal computer to help in the risk assessment of indoor-use pesticides for both applicators and indoor occupants for various methods of application including space spraying, electric vaporizing, broadcast spraying, and residual spraying. For space spraying, the movement of the pesticide in a sprayed room including droplet settlement, permeation into the floor, degradation, transference, and discharge by ventilation were described as precisely as possible by various physicochemi-cal equations. The equations thus obtained were then incorporated into the Fugacity model (Level IV).

Influence of local recurrence on the prognosis of soft-tissue sarcomas.

We have investigated the significance of local recurrence on survival in 173 patients with localised soft-tissue sarcomas of the limbs and of the trunk. The overall survival rates at five and ten years were 75.2% and 68.

Skeletal metastases from soft-tissue sarcomas. Incidence, patterns, and radiological features.

We reviewed 277 patients with soft-tissue sarcoma (STS) treated between 1975 and 1995 to study the incidence, distribution, time of appearance, and radiological findings of skeletal metastases. Of these, 28 (10.1%) had metastases within a mean period of 18.
