Linear No-Threshold Model May Not Be Appropriate for Estimating Cancer Risk from CT

Linear No-Threshold Model VS. Radiation Hormesis.

The atomic bomb survivor cancer mortality data have been used in the past to justify the use of the linear no-threshold (LNT) model for estimating the carcinogenic effects of low dose radiation. An analysis of the recently updated atomic bomb survivor cancer mortality dose-response data shows that the data no longer support the LNT model but are consistent with a radiation hormesis model when a...

AdipoRon may be benefit for atherosclerosis prevention

Atherosclerosis has serious role in coronary arteries disease,so it is important to establish effective strategies for prevention or even treatment of atherosclerosis. Adiponectin, as one of the most abundant adipokines, has insulin sensitivity, anti-inflammatory and anti-atherogenic properties. Disturbed adiponectin actions through its receptor, (AdipoR1 and AdipoR2) may be involved in atheros...

Increased Crown-To-Implant Ratio May Not Be a Risk Factor for Dental Implant Failure under Appropriate Plaque Control

OBJECTIVE The aim of this study was to evaluate whether increased crown-to-implant (C/I) ratio influences implant stability or not under proper healthy control of peri-implant mucosa. The hypothesis of this study is that implant stability can be maintained despite High C/I, under appropriate plaque control. MATERIALS AND METHODS Five male Beagle-Labrador hybrid dogs (2 years old) were used. T...

Diets high in carbohydrate may not be appropriate for rs328 G carriers with the metabolic syndrome.

The objective of this study was to test how the genetic polymorphisms located within the lipoprotein lipase (LPL) locus would modulate the relationship between a diet high in carbohydrate and insulin resistance related traits in metabolic syndrome adults. A one year nutritional intervention study focusing on education to increase dietary intake of whole grain, vegetable and fruit, and to reduce...
