Homozygous mice with a null mutation in the MMP-9/gelatinase B gene exhibit an abnormal pattern of skeletal growth plate vascularization and ossification. Although hypertrophic chondrocytes develop normally, apoptosis, vascularization, and ossification are delayed, resulting in progressive lengthening of the growth plate to about eight times normal. After 3 weeks postnatal, aberrant apoptosis, ...

Stott’s Abalone Postlarval Production System (SAPPS) was developed to replace livefood as the primary means of settling and growing out abalone seed. Culture plates are initially sprayed with microalgal powder/agar gel solution to induce larval settlement. Abalone seed are then raised on an artificial diet/agar gel solution which is sprayed directly onto the culture plates. This study was condu...

All possible haploid and diploid genotypes were created for each pair of four beneficial mutations (one in each of ERG3, ERG5, ERG6 and ERG7, main text Table 5). Each mutation was initially isolated in the BY4741 haploid background (MATa his3Δ1 leu2Δ0 met15Δ0 ura3Δ0) and given a Beneficial Mutation Nystatin (BMN) strain number [1]. Each BMN strain was mated to BY4739 (MATα leu2Δ0 lys2Δ0 ura3Δ0)...

BACKGROUND Children need physical activity and generally do this through the aspect of play. Active play in the form of organized sports can appear to be a concern for parents. Clinicians should have a general physiological background on the effects of exercise on developing epiphyseal growth plates of bone. The purpose of this review is to present an overview of the effects of physical activit...

Tibial dyschondroplasia (TD) is one of the most common problems in the poultry industry and leads to lameness by affecting the proximal growth plate of the tibia. However, due to the unique environmental and geographical conditions of Tibet, no case of TD has been reported in Tibetan chickens (TBCs). The present study was designed to investigate the effect of high altitude hypoxia on blood para...

Bovine lactoferrin (bLf) is an iron-binding secretory protein present in breast milk, mucosal secretions, and the secondary granules of neutrophils. Although bLf has multiple functions, including antimicrobial and immunomodulatory activities, its effect on neuronal cells is not fully understood. We report that bLf prevents cell adhesion of PC12 cells and allows them to be cultivated in suspensi...

conclusions bacterial resistance against chlorhexidine is increasing. sub-mic doses of chlorhexidine digluconate can stimulate the formation of biofilm strains. materials and methods forty clinical isolates of escherichia coli, salmonella serotypes, staphylococcus. aureus and streptococcus agalactiae (10 isolates for each) were examined for chlorhexidine digluconate effects on biofilm formation...

We investigate the feasibility of cohesive theories of fracture, in conjunction with the direct simulations of shear-load dominated fracture, to numerically reproduce the inter-sonic crack propagation in unidirectional graphite-epoxy composite plates [1]. The particular configuration contemplated in this study refers to the experiments performed by Coker and Rosakis [2, 3]. The numerical simula...

Surface growth of Escherichia coli cells on a membrane filter placed on a nutrient agar plate under various conditions was studied with a mathematical model. The surface growth of bacterial cells showed a sigmoidal curve with time on a semilogarithmic plot. To describe it, a new logistic model that we presented earlier (H. Fujikawa et al., Food Microbiol. 21:501-509, 2004) was modified. Growth ...
