Unusual case of intraluminal cecal recurrence of a low grade appendiceal mucinous neoplasm (LAMN)-Case report and brief literature review.

Introduction: Appendiceal mucinous neoplasms exhibit a wide spectrum of clinical behavior, ranging from neoplasms which are relatively slow-growing but with considerable risk for recurrence and eventual death and those neoplasms that are highly aggressive with increased likelihood of early death. Clinical behavior depend mainly on mucinous neoplasms grading and staging.

Presentation Of Case: We present the incidental finding of a mucinous appendiceal neoplasm in a 52 years old woman during her follow up for an operated breast carcinoma.

Antioxidant activity in rat models of nociceptive stress.

Unlabelled: Pain is an important problem and has been the subject of many studies in recent years.

Material And Method: The present study has investigated the response of the antioxidant defense systems in contention stress, which mimics nociceptive stress. Contention stress was made by immobilizing the rat, Wistar rats, on an operating table in a specific position with paws tied, for thirty minutes.

Experimental data regarding the implications of certain minimum structure enkephalin-like peptides in nociceptive processing.

The aim of this study was to investigate the importance of the amino acidic sequence at N-terminal end of certain minimum structure enkephalin-like peptides for the analgesic activity. Different groups of mice or rats were treated with 1) L-tyrosine (i.p.

New technical approaches in stereotaxic catheterization of cerebral ventriculi: implications for the L-arginine/NO synthase/nitric oxide cascade.

In order to study the actions of certain substances at cerebral level, a stereotactic device for ensuring a precise catheterization of points in certain cerebral areas was used. For the operation technique was used a stereotaxic atlas specifically designed for rat brain (G. Paxinos, C.
