Intraoperative Mitomycin C Bladder Instillation During Radical Nephroureterectomy Is Feasible and Safe.

Background: Bladder recurrence after radical treatment of upper urinary tract urothelial cancer (UTUC) is frequent, and patients are required to undergo surveillance cystoscopies following surgery. The use of intravesical adjuvant chemotherapy is an accepted method to prevent bladder recurrence, but the timing of this method is not standardized and the concept of intraoperative use is unexplored.

Objective: The objective of the study is to examine the feasibility and safety of intraoperative intravesical mitomycin C (MMC) instillation using a closed-circuit system following bladder cuff excision and bladder closure.

The discovery of bacterial biofilm in patients with muscle invasive bladder cancer.

The carcinogenic effects of microorganisms have been discovered in multiple cancer types. In urology, the development of squamous cell carcinoma of the bladder due to the parasitic infection with Schistosoma Mansoni is widely accepted. The oncogenic potential of biofilms has been studied in colorectal cancer and experimental studies have shown that bacteria such as Escherichia coli drive the development of colorectal cancer.

The Perceived Impact of Sequential Intercept Mapping on Communities Collaborating to Address Adults with Mental Illness in the Criminal Justice System.

Sequential intercept mapping is an approach to address the overrepresentation of adults with mental illness in the criminal justice system. This approach follows the sequential intercept model, a nationally recognized framework conceptualizing the linear movement of people with mental illness through the criminal justice system. During the sequential intercept mapping process, community stakeholders identify service and policy gaps and opportunities to address the needs of this target population.

Pavlovian to instrumental transfer of control in a human learning task.

Pavlovian learning tasks have been widely used as tools to understand basic cognitive and emotional processes in humans. The present studies investigated one particular task, Pavlovian-to-instrumental transfer (PIT), with human participants in an effort to examine potential cognitive and emotional effects of Pavlovian cues upon instrumentally trained performance. In two experiments, subjects first learned two separate instrumental response-outcome relationships (i.

Subdivision of the mitotic cycle into eleven stages, on the basis of the chromosomal changes observed in mouse duodenal crypt cells stained by the DNA-specific Feulgen reaction.

The Feulgen reaction has been utilized to localize DNA in nuclei throughout the cycle of mouse duodenal crypt cells using Epon-embedded 1 micron thick sections. The observed changes indicate that the 12.3 h long mitotic cycle of these cells can be subdivided into eleven stages, seven of which take place during the interphase.

Role of apical tubules in endocytosis in nonciliated cells of the ductuli efferentes of the rat: a kinetic analysis.

The apical region of nonciliated cells of the ductuli efferentes of the rat contains tubular coated pits (TCP) connected to the apical plasma membrane, apical tubules (AT) which occasionally show a partial coat, and endosomes which are often continuous with one or more apical tubules. To investigate the formation and fate of TCP and AT, a quantitative analysis was performed on the labeling indices of these structures at various time intervals (0.5-120 min) after a single injection of a tracer, cationic ferritin (CF), into the lumen of the rete testis.

Cyclic endocytic activity and kinetics of lysosomes in Sertoli cells of the rat: a morphometric analysis.

Native ferritin was injected into the rete testis of rats, and seminiferous tubules infused with the tracer were collected 6 h later and prepared for electron microscopic analysis. As a result of internalization of the tracer by Sertoli cells, label was found within 12-66% of the secondary lysosomes, depending on the stage of the cycle of the seminiferous epithelium. The Zeiss MOP-3 instrument was used on selected electron microscope photographs to measure a number of morphometric parameters.

Analysis of gland cell behavior: appendix to the dynamic histology of the antral epithelium in the mouse stomach.

The origin, route of migration, and ultimate fate of mucous gland cells in mouse antral units have been described in the preceding article. Three regions of the mucous gland, consisting of gland neck cells, mid-gland cells, and gland base cells, respectively were defined; and the renewal events in each of these regions were studied. In this article, the data obtained by Lee and Leblond (1985) were subjected to a mathematical analysis to obtain additional information about the rate of loss of cells.

Assessment of resolution by half distance values for tritium and radioiodine in electron microscopic radioautographs using Ilford L4 emulsion developed by "solution physical" or D-19b methods.

Half distance values for electron microscopic (EM) radioautographs with the isotopes 3H and 125I were determined using Ilford L4 emulsion processed with either fine grain, solution physical development, or filamentous grain, chemical development with D-19b. 3H- and 125I-line sources, obtained by cutting perpendicular sections from sections of 3H-labeled methacrylate or 125I-labeled thyroid glands, were processed for EM radioautography. The distribution of silver grains around a line source was determined by measuring their distance from the source in photographs of EM radioautographs.

Quantitation and resolution in electron microscope radioautography.

Electron microscopy can resolve structures with accuracy of the order of 0.2-0.3 nm, but the radioautographic technique is able to locate radioactive label with much less certainty, at best 50 nm.

Polypeptide hormone binding sites in vivo: initial localization of 125I-labeled insulin to hepatocyte plasmalemma as visualized by electron microscope radioautography.

The rationale of the specific-binding assay was applied to the detection of the liver insulin receptor in vivo. Quantitative electron microscope radioautography indicated that, 3 min after an intraportal injection, 125I-insulin was exclusively located to the hepatocyte plasmalemma.

Absence of an alpha two-macroglobulin-protease complex in cystic fibrosis.

The present study using immunologic methodology confirms previous observations from this laboratory of an absence of a protease component with arginine esterase activity in plasma of patients with cystic fibrosis. In this study, the pooled plasma from control individuals was activated and partially purified after adsorption on columns of soybean trypsin inhibitor conjugated to Sepharose 4B followed by elution with benzamidine. The fraction was further purified by isoelectrofocusing on polyacrylamide gels.

Renewal of the epithelium in the descending colon of the mouse. IV. Cell population kinetics of vacuolated-columnar and mucous cells.

Proliferation and migration of cells in the vacuolated-columnar and mucous cell lines were studied in the descending colon of adult female mice given a single injection or a continuous infusion of 3H-thymidine and killed at various intervals from one hour to 12 days. This investigation was carried out using one mum-thick Epon sections which were radioautographed after staining with the periodic acid-Schiff technique and iron-hematoxylin. In the normalized crypts with ten equal segments, labeled vacuolated cells at one hour after injection of 3H-thymidine were encountered in the lower four segments and in decreasing numbers in segments 5 through 7.

[Thyroid pigments in Gunn rats].

The structural and histochemical characteristics of the thyroid pigment in homozygous Gunn rats were examined. The pigment occurs in the form of numerous yellow granules in the cytoplasm of the follicular cells. The focal depositions of the pigment were also seen in the central part of the luminal colloid.

Radioautographic study of in vivo and in vitro incorporation of fucose-3H into thyroglobulin by rat thyroid follicular cells.

The incorporation of fucose-(3)H in rat thyroid follicles was studied by radioautography in the light and electron microscopes to determine the site of fucose incorporation into the carbohydrate side chains of thyroglobulin, and to follow the migration of thyroglobulin once it had been labeled with fucose-(3)H. Radioautographs were examined quantitatively in vivo at several times after injection of fucose-(3)H into rats, and in vitro following pulse-labeling of thyroid lobes in medium containing fucose-(3)H. At 3-5 min following fucose-(3)H administration in vivo, 85% of the silver grains were localized over the Golgi apparatus of thyroid follicular cells.
