[Retroperitoneoscopic resection of the calyceal diverticulum wall in an 8-year-old child].

A renal calyceal diverticulum is a cystic cavity within the renal parenchyma, which is lined by transitional epithelium and communicates with the calyx or, more rarely, the renal pelvis. In children, this anomaly is extremely rare. The article describes the resection of the middle calyceal diverticulum in an 8-year-old child using retroperitoneoscopic access.

It is well known that aging is the natural growing multisection biological process inevitably leading to limitation of body adaptive capabilities. The body ageing is the result of self-regulation mechanism limitation, reduction of their potential capabilities at molecular-genetic, energetic, cellular and general-regulatory levels. It should be noted that due to lack of the unified theory of aging the importance of nutrition factor has been acknowladged particularly initiation and intensity of the process, and the role of antioxidants is discussed much in detail.

Ex vivo laser thermoplasty of whole costal cartilages.

Background And Objective: To examine the possibilities of laser thermoplasty of whole costal cartilages for correction the human congenital chest wall deformities.

Study Design/materials And Methods: Ex vivo the samples of porcine costal cartilages were heated with lasers of differing wavelengths, including a 0.97-μm diode laser, a 1.
