Thin Film TaFe, TaCo, and TaNi as Potential Optical Hydrogen Sensing Materials.

This paper studies the structural and optical properties of tantalum-iron-, tantalum-cobalt-, and tantalum-nickel-sputtered thin films both ex situ and while being exposed to various hydrogen pressures/concentrations, with a focus on optical hydrogen sensing applications. Optical hydrogen sensors require sensing materials that absorb hydrogen when exposed to a hydrogen-containing environment. In turn, the absorption of hydrogen causes a change in the optical properties that can be used to create a sensor.

Computer-aided identification of prostatic adenocarcinoma: Segmentation of glandular structures.

Background: Identification of individual prostatic glandular structures is an important prerequisite to quantitative histological analysis of prostate cancer with the aid of a computer. We have developed a computer method to segment individual glandular units and to extract quantitative image features, for computer identification of prostatic adenocarcinoma.

Methods: TWO SETS OF DIGITAL HISTOLOGY IMAGES WERE USED: database I (n = 57) for developing and testing the computer technique, and database II (n = 116) for independent validation.

Addisonian crisis and tuberculous epididymo-orchitis.

Objective: To describe a case of acute primary adrenal insufficiency in which tuberculosis was subsequently detected as the etiologic factor when the patient presented with tuberculous epididymo-orchitis.

Methods: A case of acute primary adrenal insufficiency associated with bilaterally enlarged adrenal glands is reported, along with the subsequent finding of a scrotal mass diagnosed as tuberculous epididymo-orchitis. Diagnosis, adrenal function, and results of imaging studies after institution of antituberculous treatment are discussed.

Adenovirus-mediated tumor-specific combined gene therapy using Herpes simplex virus thymidine/ganciclovir system and murine interleukin-12 induces effective antitumor activity against medullary thyroid carcinoma.

The present treatment of advanced and metastatic medullary thyroid carcinoma (MTC) is unsatisfactory. Tissue-specific cancer gene therapy is a novel alternative approach. We developed a recombinant adenovirus expressing Herpes simplex type 1 thymidine kinase (HSVtk) driven by a modified CALC-I promoter TCP (AdTCPtk).
