Fundamental principles in periodontal plastic surgery and mucosal augmentation - a narrative review

submitted by: Rino
Aim: To provide a narrative review of the current literature elaborating on fun- damental principles of periodontal plastic surgical procedures. Methods: Based on a presumptive outline of the narrative review, MESH terms have been used to search the relevant literature electronically in the PubMed and Cochrane Collaboration databases. If possible, systematic reviews were included. The review is divided into three phases associated with periodontal plastic sur- gery: a) pre-operative...

Science Behind the News: Influenza & Flu Vaccines

submitted by: nsf

Every flu season, Americans battle coughs, fevers and body aches. The flu is a respiratory illness caused by a virus, a pathogen that causes disease in the human body. To understand how the flu is caught, spread and treated, Duke University's Katia Koelle explains the biology of a virus and how it is transmitted.

Health effect of the New Nordic Diet in adults with increased waist circumference: a 6-mo randomized controlled trial.

submitted by: skp
BACKGROUND: The regional Mediterranean Diet has been associated with lower risk of disease. OBJECTIVE: We tested the health effects of the New Nordic Diet (NND), which is a gastronomically driven regional, organic, and environmentally friendly diet, in a carefully controlled but free-living setting. DESIGN: A total of 181 centrally obese men and women, with a mean (range) age of 42 y (20-66 y), body mass index (in kg/m(2)) of 30.2 (22.6-47.3), and waist circumference of 100 cm (80-138...

Silencing the Menkes Copper-Transporting ATPase (Atp7a) Gene in Rat Intestinal Epithelial (IEC-6) Cells Increases Iron Flux via Transcriptional Induction of Ferroportin 1 (Fpn1)

submitted by: jfcollins
The Menkes copper-transporting ATPase (Atp7a) gene is induced in rat duodenum during iron deficiency, consistent with copper accumulation in the intestinal mucosa and liver. To test the hypothesis that ATP7A influences intestinal iron metabolism, the Atp7a gene was silenced in rat intestinal epithelial (IEC-6) cells using short hairpin RNA (shRNA) technology. Perturbations in intracellular copper homeostasis were noted in knockdown cells, consistent with the dual roles of ATP7A in pumping...

The addition of soft tissue replacement grafts in plastic periodontal and implant surgery: critical elements in design and execution

submitted by: Otto Zuhr
Soft tissue replacement grafts have become a substantial element to increase tissue volume in plastic periodontal and implant surgery. Autogenous subepithelial connective tissue grafts are increasingly applied in aesthetic indications like soft tissue thickening, recession treatment, ridge preservation, soft tissue ridge augmentation and papilla reconstruction. For the clinical performance of connective tissue graft harvesting and transplantation, a fundamental understanding of the anatomy...
