The extent of damage surrounding an implanted electrode in the cerebral cortex is a question of significant importance with regard to attaining consistency and validity of physiological recordings. In order to determine the extent of such tissue changes, 150 micron diameter platinum electrodes were implanted in the cortex of four adult baboons, and after eight days the animals were sacrificed by whole body perfusion with a 3% glutaraldehyde in 0.1M phosphate fixative.The calvarium was carefully removed and the electrode tracts were readily discernible in the firm, glutaraldehyde fixed tissue.Careful dissection of the zone of the electrode tract resulted in a small block which was further sectioned into tip, mid-tract and surface areas. Ultrastructurally, damage extended from the electrode sheath to the greatest extent of from 0.2 to 3.5 mm.

Connective Tissue Stroma

The differentiation and maintenance of many specialized epithelial structures are dependent on the underlying connective tissue stroma and on an intact basal lamina. These requirements are especially stringent in the development and maintenance of the skin and oral mucosa. The keratinization patterns of thin or thick cornified layers as well as the appearance of specialized functional derivatives such as hair and teeth can be correlated with the specific source of stroma which supports these differentiated expressions.

BACKGROUND: Checkpoint inhibitors and receptor tyrosine kinase inhibitors (RTKIs) have changed the standard of care for metastatic renal cell carcinoma (mRCC). Anecdotal evidence suggests these therapies may be less effective for treating bone than soft-tissue metastases. PURPOSE: We performed a retrospective review evaluating the relative clinical responses in soft-tissue and bone metastases in patients undergoing therapy using RTKIs and anti-programmed death-1 (PD-1) agents for mRCC. METHODS: Of the 2,212 patients in our institutional cancer registry with renal cell carcinoma (1997–2017), 68 (82 disease courses) were identified with measurable bone and soft-tissue metastases treated with RTKIs and/or PD-1s. Extent of metastasis was quantified at the time of therapy initiation (baseline) and at 3 months, 6 months, and 1 year. Changes in disease status were categorized as complete response, partial response, stable, mixed, or progression of disease according to RECIST v1.1 and MD Anderson criteria. These categories were further organized into “response to treatment” or “evidence of progression” to generate a generalized linear effects model with soft-tissue response as the independent variable and bone response as the dependent variable. Alpha = 0.05. RESULTS: Soft-tissue response correlated with bone response at 3 months (76 disease courses, p = 0.005) and 6 months (48 disease courses, p = 0.017). Of the patients with controlled soft-tissue disease, only 14 (19%) and 15 (32%) had progression in bone at 3 and 6 months, respectively. CONCLUSION: Contrary to anecdotal reports, osseous metastases do not appear to respond worse than soft-tissue metastases to treatment with these agents.

AbstractCarbon nanofibers possess excellent conductivity properties, which may be beneficial in the design of more effective neural prostheses, however, limited evidence on their cytocompatibility properties exists. The objective of the present in vitro study was to determine cytocompatibility and material properties of formulations containing carbon nanofibers to predict the gliotic scar tissue response. Poly-carbonate urethane was combined with carbon nanofibers in varying weight percentages to provide a supportive matrix with beneficial bulk electrical and mechanical properties. The substrates were tested for mechanical properties and conductivity. Astrocytes (glial scar tissue-forming cells) were seeded onto the substrates for adhesion. Results provided the first evidence that astrocytes preferentially adhered to the composite material that contained the lowest weight percentage of carbon nanofibers. Positive interactions with neurons, and, at the same time, limited astrocyte functions leading to decreased gliotic scar tissue formation are essential for increased neuronal implant efficacy.
