A Multi-aperture Coaxial Projector Balancing Shadow Suppression and Deblurring.

This paper proposes a projection system that optically removes the cast shadow in projection mapping. Specifically, we realize the large-aperture (LA) projection using a large-format Fresnel lens to suppress cast shadows by condensing the projection light from a wide viewing angle. However, the resolution and contrast of the projected results are significantly degraded by defocus blur, veiling glare, and stray light caused by the aberration of an LA Fresnel lens.

Projection Mapping under Environmental Lighting by Replacing Room Lights with Heterogeneous Projectors.

Projection mapping (PM) is a technique that enhances the appearance of real-world surfaces using projected images, enabling multiple people to view augmentations simultaneously, thereby facilitating communication and collaboration. However, PM typically requires a dark environment to achieve high-quality projections, limiting its practicality. In this paper, we overcome this limitation by replacing conventional room lighting with heterogeneous projectors.

A single 2 g oral dose of extended-release azithromycin for treatment of gonococcal urethritis.

Objectives: We treated gonococcal urethritis in men with a single 2 g dose of azithromycin extended-release formulation (azithromycin-SR) to determine its microbiological outcomes and tolerability.

Patients And Methods: We enrolled 189 Japanese men with gonococcal urethritis between April 2009 and December 2013. The patients were given a single 2 g dose of azithromycin-SR.

Evaluation of the effects of acupuncture on blood flow in humans with ultrasound color Doppler imaging.

Color Doppler imaging (CDI) can be used to noninvasively create images of human blood vessels and quantitatively evaluate blood flow in real-time. The purpose of this study was to assess the effects of acupuncture on the blood flow of the peripheral, mesenteric, and retrobulbar arteries by CDI. Statistical significance was defined as P values less than 0.

Report on disaster medical operations with acupuncture/massage therapy after the great East Japan earthquake.

The Great East Japan Earthquake inflicted immense damage over a wide area of eastern Japan with the consequent tsunami. Department of Traditional Asian Medicine, Tohoku University, started providing medical assistance to the disaster-stricken regions mainly employing traditional Asian therapies.We visited seven evacuation centers in Miyagi and Fukushima Prefecture and provided acupuncture/massage therapy.

Extracorporeal shock wave lithotripsy and xanthine calculi in Lesch-Nyhan syndrome.

We report a case of Lesch-Nyhan syndrome (LNS) with urinary xanthine calculi. At eight years of age calculi in the renal pelvis were successfully disintegrated by extracorporeal shock wave lithotripsy (ESWL) without any complications. Follow-up sonography is very useful for management of patients with LNS, particularly when they are on allopurinol therapy.

[Effect of extracorporeal shock wave lithotripsy on renal function-an experience with the new type piezoelectric lithotripter, Therasonic].

Seventeen patients with renal stones and 17 patients with ureteral stones were treated using the newly developed piezoelectric shock wave lithotripter, THERASONIC. To determine the effect of shock wave on renal function, urinary N-acetyl-beta-D-glucosaminidase (NAG) activity, urinary beta 2 microglobulin (BMG) concentration, serum BMG concentration and creatinine clearance (Ccr) were measured. Urinary NAG activity and urinary BMG concentration in renal stone patients were significantly elevated immediately after the treatment and returned to the pretreatment value within 24 hours.

[Treatment of urinary stones with Therasonic, the third generation piezoelectric shock wave lithotripter].

The THERASONIC lithotripsy treatment system, a newly developed piezoelectric lithotripter, uses both an X-ray and ultrasound system and enables stone localization effective. Treatment of urinary stones with THERASONIC was begun in June, 1989 and 57 treatments have already been performed on 38 patients. Successful treatment, defined as either stone free or with a residual stone less than 4 mm in diameter on flat X-ray film, was accomplished in 95% of the renal stones and over 50% of the ureteral stones.

[A case of advanced prostatic cancer in a 44-year-old treated effectively with combination chemo-endocrine therapy].

In a 44-year-old man with persistent back-pain for 3 months duration, radiological and echological investigations revealed prostatic mass lesion with multiple osteoblastic involvements. Transrectal biopsy to the prostate demonstrated pathohistologically poorly differentiated adenocarcinoma (Gleason's score 4-4:8). Serum ACP, ALP and IAP were elevated at the initial diagnosis pathologically.

[Lung metastases of prostatic cancer vanished by early combined hormonal and chemotherapy: report of a case].

A 69-year-old man initially came to our hospital with the chief complaint of dysuria and hematuria. On rectal examination, the prostate gland was found to be grossly enlarged and rock hard in consistency. Abnormal laboratory data included: lactate dehydrogenase, alkaline phosphatase, acid phosphatase and prostatic acid phosphatase.

[A case of giant obsolete hydrocele testis].

A 58-year-old man visited the urological clinic in Prefectural Tohkamachi Hospital with complaint of swelling of bilateral scrotal contents. He had no history of fever, pain or difficulty of urination. Physical examination revealed a giant mass of adult-head size in right scrotum and left inguinal hernia of fist growth.

[Histologic grading of primary prostatic carcinoma--study of Gleason histologic grading].

Gleason histologic grading for prostatic carcinoma was evaluated in a retrospective analysis. The present study comprises 98 cases of prostatic adenocarcinoma followed from January, 1973 to December, 1985. Histological materials were obtained by needle biopsy, transurethral resection or by suprapubic prostatectomy.

[Bilateral simultaneous upper urothelial tumors--6 and a half years postoperative follow-up study].

A 67-year-old man was admitted with the chief complaint of asymptomatic intermittent gross hematuria on June 22, 1978. No tumor was found cystoscopically. But urinary cytology indicated class IV.

[Prostate cancer].

The incidence of prostate cancer has recently increased in Japan. Since Huggins demonstrated the dramatic effect of antiandrogenic treatment, patients with prostate cancer are widely treated by bilateral orchiectomy and high dose estrogen. As the incidence of cardiovascular disease has also gradually increased in patients of prostate cancer treated by estrogen in Japan, radiotherapy, radical prostatectomy, antiandrogen such as chlormadinone acetate, cyproterone acetate and anticancer chemotherapy are now sought and tested clinically.

[Chemotherapy of metastatic urothelial carcinoma. cis-Diamminedichloroplatinum combination chemotherapy for patients with decreased renal function].

Cis-diamminedichloroplatinum (CDDP) combination chemotherapy has induced a high response rate in the treatment of metastatic urothelial carcinoma at our clinic. However, due to the risks of renal failure, renal function manifested by creatinine clearance (Ccr) of more than 50 ml/min is suggested to be the requirement for CDDP therapy. Unfortunately, some patients do not meet this requirement.

[Diagnosis and treatment of carcinoma of the prostate].

The incidence of carcinoma of the prostate has recently increased in Japan, but it is still considerably less frequent than in other countries. The highest incidence of carcinoma of the prostate occurs at around 70 years of age, and more than half of all cases are in stage C and D when detected in Japan. Antiandrogenic treatment is still widely used, but unfortunately, results are unsatisfactory in terms of control and survival rates.
