Retention of Approximal Guiding Plane Surfaces in Removable Partial Skeletal Prosthesis.

Background: The morphology of the retention tooth often does not correspond with the required design; hence there is often an indication for enamel recontouring or other restorative procedures.

Aim: The study aimed to determine the impact of changing the path of insertion of the prosthesis by reshaping the anatomical and morphological structures of the natural teeth predetermined for the retention of the prosthesis.

Material And Methods: The group of 40 patients with Class II, Subclass 1 according to Kennedy was formed, and 120 approximal surfaces of retention teeth were obtained.

Free Gingival Graft versus Mucograft: Histological Evaluation.

Introduction: The correction of the gingival recession is of esthetical and functional significance, but the tissue regeneration can only be confirmed by a histological examination.

Aim: This study aims to make a comparison between the free gingival graft and the autograft.

Material And Methods: This study included 24 patients with single and multiple gingival recessions.

Colovaginal anastomosis: A totally unacceptable surgical error.

Introduction: The low anterior rectal resection and double stapling technique are well-established surgical procedures with well-known pitfalls, potential complications, and preventive measures. Colovaginal anastomosis is a surgical error which should not occur.

Presentation Of Case: A 39-year old woman underwent low anterior resection with double stapling technique, for rectal carcinoma in the City Hospital.

Identification of an atypical lipoprotein-binding protein from human aortic smooth muscle as T-cadherin.

We have previously described an atypical lipoprotein-binding protein of about 105 kDa (p105) in membranes of vascular smooth muscle cells (VSMCs) that is distinct from currently known lipoprotein receptors. In the present work we have developed a procedure for purification of p105 from human aortic media. Partial sequencing of purified protein has revealed identity of p105 with human T-cadherin.

Bioartificial liver using hepatocytes on biosilon microcarriers: treatment of chemically induced acute hepatic failure in rats.

An artificial liver support procedure based on hemoperfusion via hepatocytes cultured on microcarriers is described. The efficiency of the system was assessed by the survival rate of rats treated with either lethal dosage of 7% CCl4 [30 ml/kg body weight (b.w.
