Tunnel motion: Pupil dilations to optic flow within illusory dark holes.

We showed to the same observers both dynamic and static 2D patterns that can both evoke distinctive perceptions of motion or optic flow, as if moving in a tunnel or into a dark hole. At all times pupil diameters were monitored with an infrared eye tracker. We found a converging set of results indicating stronger pupil dilations to expansive growth of shapes or optic flows evoking a forward motion into a dark tunnel.

Illusory motion and vection induced by a printed static image under flickering ambient light at rates up to 100 Hz.

Visual motion signals can produce self-motion perception known as vection in observers. Vection can be generated by illusory motions in the form of global expantion in still images as well as by visual motion signals. The perception of vection can be enhanced by flickering images at a rate of 5 Hz.

A novel treatment based on powder jet deposition technique for dentin hypersensitivity: a randomized controlled trial.

Background: This study aimed to evaluate the efficacy and safety of dentin hypersensitivity (DH) treatment using a newly developed device based on a powder jet deposition (PJD) technique that creates a hydroxyapatite (HAP) layer on the dentin surface, thereby alleviating the hypersensitivity. The effect of the PJD treatment was compared with that of conventional treatment using Teethmate Desensitizer (TMD; calcium-phosphate containing material with TTCP (Ca(PO)O) and DCPA (CaHPO)), which has been used clinically in Japan with well-confirmed effectiveness.

Materials And Methods: A randomized controlled trial was conducted including 35 patients who had symptoms of DH in two or more quadrants.

The zooming-speed illusion: A meta illusion?

A movie taken from the front window of a running train, with zooming in and out, has been popularly acknowledged as a perceptual illusion such that the train motion is perceived as much slower when zoomed in. This is, however, not a real illusion because the image speed varies as a function of the focal length of the lens. This could be a meta-illusion, that is, an illusory sense of illusion, that might reflect a lack of understanding of how zooming changes the geometrical structure of the image.

Successful Surgical Treatment of a Recurrent Pelvic Solitary Fibrous Tumor of Uterine Origin Accompanied by Doege-Potter Syndrome: A Case Report.

BACKGROUND Solitary fibrous tumors (SFT), rare soft-tissue neoplasms, are usually found in the thoracic cavity, and a uterine origin is extremely rare. SFTs with insulin-like growth factor-II (IGF-II) production induce non-islet cell tumor-induced hypoglycemia (NICTH), referred to as Doege-Potter syndrome. CASE REPORT A 70-year-old woman presented with urinary retention, and imaging revealed a huge mass occupying almost the entire pelvic space.

Effects of Calcium Polystyrene Sulfonate Formulation Change from Dry Syrup to Oral Solution in Patients with Chronic Kidney Disease.

Calcium polystyrene sulfonate, a cation exchange resin preparation, is used to treat hyperkalaemia. The effects of switching from dry syrup to oral solution forms have been rarely evaluated. We investigated changes in serum potassium levels, incidence of adverse events, and patients' perception and satisfaction associated with the change in calcium polystyrene sulfonate dosage forms from dry syrup to oral solution in chronic kidney disease patients.

Simple Assumptions to Improve Markov Illuminance and Reflectance.

Murray recently introduced a novel computational lightness model, Markov illuminance and reflectance (MIR). MIR is a promising new approach that simulates human lightness processing using a conditional random field (CRF) where natural-scene statistics of reflectance and illumination are implemented. Although MIR can account for various lightness illusions and phenomena, it has limitations, such as the inability to predict reverse-contrast phenomena.

Safety of linezolid, rifampicin, and clindamycin combination therapy in patients with prosthetic joint infection.

We investigated adverse events in patients with prosthetic joint infections receiving combination therapy with linezolid, rifampicin, and clindamycin for ≥ 7 days. Twenty-two patients were evaluated. The combination therapy was administered for 15.

The Eye Pupil Adjusts to Illusorily Expanding Holes.

Some static patterns evoke the perception of an illusory expanding central region or "hole." We asked observers to rate the magnitudes of illusory motion or expansion of black holes, and these predicted the degree of dilation of the pupil, measured with an eye tracker. In contrast, when the "holes" were colored (including white), i.

Usefulness of conventional glass ionomer cements in an environment of insufficient moisture exclusion.

Purpose: Moisture exclusion while treating dental caries can be challenging, and the glass ionomer cements (GICs) used for these procedures are susceptible to water. Few studies have examined the effects of the powder/liquid ratio (PLR) on the physical properties of GICs exposed to water. In this study, the hardness and thickness of the water-susceptible surface layer of three GICs were evaluated.

Motion illusion-like patterns extracted from photo and art images using predictive deep neural networks.

In our previous study, we successfully reproduced the illusory motion perceived in the rotating snakes illusion using deep neural networks incorporating predictive coding theory. In the present study, we further examined the properties of the network using a set of 1500 images, including ordinary static images of paintings and photographs and images of various types of motion illusions. Results showed that the networks clearly classified a group of illusory images and others and reproduced illusory motions against various types of illusions similar to human perception.

Successful treatment with metronidazole and paromomycin for fulminant amoebic colitis during cytotoxic chemotherapy in a patient with small-cell lung cancer.

We report the case of a 64-year-old man with advanced small-cell lung cancer who developed fulminant amoebic colitis during cytotoxic chemotherapy. During the first cycle of carboplatin/etoposide treatment, febrile neutropenia and grade 4 neutropenia developed. Because diarrhea, abdominal pain, and bloody stool were observed, abdominal computed tomography was performed, showing intussusception, and extensive colectomy and colostomy were performed.

Bronchial Artery Aneurysm: Prevalence, Clinical Characteristics, and Long-Term Prognosis Following Bronchial Artery Embolization.

Purpose: To investigate the prevalence, clinical characteristics, and long-term prognosis of bronchial artery aneurysm (BAA) following bronchial artery embolization (BAE).

Materials And Methods: The medical records of consecutive patients who underwent bronchial artery angiography between August 2013 and December 2019 were retrospectively reviewed. Patients who were diagnosed with BAA during this period were included in this study.

Efficacy and safety of tedizolid in a patient with linezolid-induced neutropenia: A case report.

Linezolid is used to treat prosthetic joint infection after total hip arthroplasty. Here, we present a case of linezolid-induced severe neutropenia, which improved after switching to tedizolid. Grade 3 neutropenia developed 5 days after linezolid injection (1,200 mg/day) and 33 days after oral administration of the same dose.

Bronchoscopic Surgery for a Solitary Tracheal Tumor of Tracheobronchopathia Osteochondroplastica.

Tracheobronchopathia osteochondroplastica is a rare benign condition in which multiple cartilaginous or bony submucosal nodules project into the trachea or bronchi. A 71-year-old man complained of cough for 3 months. Computed tomography scanning revealed a calcified tracheal tumor near the tracheal bifurcation.

Cross-modal size-contrast illusion: Acoustic increases in intensity and bandwidth modulate haptic representation of object size.

Changes in the retinal size of stationary objects provide a cue to the observer's motion in the environment: Increases indicate the observer's forward motion, and decreases backward motion. In this study, a series of images each comprising a pair of pine-tree figures were translated into auditory modality using sensory substitution software. Resulting auditory stimuli were presented in an ascending sequence (i.

Reversed Phi and the "Phenomenal Phenomena" Revisited.

Reversed apparent motion (or reversed phi) can be seen during a continuous dissolve between a positive and a spatially shifted negative version of the same image. Similar reversed effects can be seen in stereo when positive and spatially shifted negative images are presented separately to the two eyes or in a Vernier alignment task when the two images are juxtaposed one above the other. Gregory and Heard reported similar effects that they called "phenomenal phenomena.

Blindness to Curvature and Blindness to Illusory Curvature.

We compare two versions of two known phenomena, the and the illusions, to highlight how similar manipulations lead to blindness to curvature and blindness to illusory curvature, respectively. The critical factor is a change in luminance polarity; this factor interferes with the computation of curvature along the contour, for both real and illusory curvature.

Illusory Motion Reproduced by Deep Neural Networks Trained for Prediction.

The cerebral cortex predicts visual motion to adapt human behavior to surrounding objects moving in real time. Although the underlying mechanisms are still unknown, predictive coding is one of the leading theories. Predictive coding assumes that the brain's internal models (which are acquired through learning) predict the visual world at all times and that errors between the prediction and the actual sensory input further refine the internal models.

Clinical Evaluation of Monolithic Zirconia Crowns: A Short-Term Pilot Report.

Purpose: This study aimed to prospectively evaluate the clinical performance of monolithic zirconia crowns made of yttria-stabilized tetragonal zirconia polycrystal.

Materials And Methods: A total of 26 crowns placed on premolar or molar teeth in 18 patients were evaluated at the time of crown placement and at 2 weeks, 6 months, 1 year, and 2 years after placement.

Results: Twenty-five crowns rated as satisfactory according to the California Dental Association quality evaluation system.

Kitaoka's Tomato: Two Simple Explanations Based on Information in the Stimulus.

Kitaoka's Tomato is a color illusion in which a semitransparent blue-green field is placed on top of a red object (a tomato). The tomato appears red even though the pixels would appear green if viewed in isolation. We show that this phenomenon can be explained by a high-pass filter and by histogram equalization.

Manual on the proper use of lutetium-177-labeled somatostatin analogue (Lu-177-DOTA-TATE) injectable in radionuclide therapy (2nd ed.).

Here we present the guideline for the treatment of neuroendocrine tumors using Lu-177-DOTA-TATE on the basis of radiation safety aspects in Japan. This guideline was prepared by a study supported by Ministry of Health, Labour, and Welfare, and approved by Japanese Society of Nuclear Medicine. Lu-177-DOTA-TATE treatment in Japan should be carried out according to this guideline.
