In this study, a spindle-type nozzle was designed to accelerate poly-L-lactic acid (PLLA) microparticles to supersonic velocities for the transdermal delivery of these microparticles to rats. This approach is needle- and pain-free and enhances skin collagen regeneration. The addition of PLLA microparticles at a concentration of 2 mg/mL did not hinder the growth of 3 T3 fibroblasts and Raw264.

Purpose: Thallium-201 (201Tl) is a recognized tumor-imaging agent; however, the usefulness of 201Tl in prostate cancer has not been studied. The purpose of this preliminary study was to evaluate the efficacy of 201Tl single-photon emission computed tomography (SPECT) imaging for differentiating prostate cancer from benign prostatic hyperplasia (BPH).

Methods: 201Tl pelvic SPECT was performed in 10 patients (aged 64-78 years) with biopsy-proven BPH before transurethral resection of the prostate and 15 patients (aged 65-81 years) with biopsy-proven prostate cancer prior to any therapeutic modality or invasive surgical procedures for treatment of their prostate cancer.

Purpose: Torsion of the testis is a urologic emergency that requires early diagnosis and prompt surgical treatment for testicular survival. However, the early differential diagnosis of acute testicular torsion from epididymitis or orchitis is often difficult. The aim of this retrospective study was to evaluate and compare the value of Tc-99m pertechnetate radionuclide imaging and ultrasonography in the differentiation of acute testicular torsion and inflammatory testicular diseases.
