Stress fractures are overuse injuries of bone that affect elite athletes and military recruits. One response of cortical bone to stress fracture is to lay down periosteal callus. The objectives of this study were to determine if material properties are different among bones with different stages of stress fracture callus, at both a callus site and at a distal site. Cortical specimens were mecha...

INTRODUCTION The treatment of bone fracture is an important public health problem in an ageing population. Healing involves a series of biological events that restores the tissue to its original shape and mechanical properties. It has been shown that the mechanical environment can modulate tissue differentiation. Several mechanoregulatory algorithms have been proposed to predict tissue differen...

Abstract The method for micro-propagation of rubber ( Hevea brasiliensis Muell. Arg ) by somatic embryo has been conducted. aim the research will describe effect media used callus induction on formation plants. Embryonic had in 3 media, i.e.; MH1, MH2, and MH3. After induction, all were induced expression. Maturation cotyledons was performed using liquid with filter paper as a bridge to absorb ...

In this study, studies were conducted to optimize callus and suspension culture methods for in vitro mutation breeding purple orange carrots. Following this, the developed mutant lines subjected salt stress selection. The study determined optimal agar dose. first germination, 50% root-cotyledon formation genuine leaf carrot seedlings analyzed daily which was continued with 7g/L cotyledon hypoco...

Previous studies have shown substantial effect thermal damage can have on new bone formation following osteotomy. In this study we evaluated the extent of thermal damage which occurs in four different methods of osteotomy and the effects it can have on bone healing. We further wanted to test whether a special osteotomy plate we constructed can lead to diminished heat generation during osteotomy...

Plant cells have a remarkable ability to induce pluripotent cell masses and regenerate whole plant organs under the appropriate culture conditions. Although the in vitro regeneration system is widely applied to manipulate agronomic traits, an understanding of the molecular mechanisms underlying callus formation is starting to emerge. Here, we performed genome-wide transcriptome profiling of wil...

Among the flowering plants, the members of cucurbitaceae are duly useful for human being that is agood source of vegetables and also a better resource for phytochemical compounds. The present study was aimed to induce the callus from in vitro grown seedling explants. The effect of BAP and NAA have been investigated, the combination of BAP and NAA results in the higher callus induction. The call...

A mutagenesis programme was carried out using physical mutagens (gamma rays) on Cucumis melo cv. Bathasa. In irradiated seeds the number of shoots formed in the lower doses was significantly higher than the controls. Decrease in the number of shoots and shoot bud formation was observed with higher doses in all the explants studies. There was complete lethality in the 10, 15 and 20 kR doses. In ...
