The diamondback moth (DBM), Plutella xylostella (L.), remains a major pest of brassica crops worldwide. DBM has been estimated globally to cost US$ 1 billion in direct losses and control costs. Chemical control of this pest remains difficult due to the rapid development of resistance to insecticides and to their effect on natural enemies. These problems are especially severe in South Asia and A...

BACKGROUND Delayed union of fractured bone is one of the main problems of orthopedics and traumatology practice. It was hypothesized that the beneficial effects of allogeneic platelet-rich plasma (PRP) would be valuable in the treatment of segmental bone defects. This study is a comparison of the effects of demineralized bone matrix (DBM) and PRP in a segmental bone defect model. METHODS Tota...

AIMS the aim of the Di Bella Method (DBM) is to try to overcome the high toxicity level and the limited efficacy of the current medical treatments for cancer. METHOD using Melatonin, Retinoids, and vitamins E, D3, and C, components of the extracellular matrix, the DBM reinforces those means that Physiology considers essential for life. Acting together, these differentiating molecules also hav...

The encapsulation of [Eu(dbm)3phen] into functionalized mesoporous silica nanoparticles (MSN) has been carried out to study the effect of chemical environments on the photoluminescence properties of the rare-earth complex. Surface functionalization was achieved by the reaction of the silanol groups on the surface of mesoporous silica with different organosilylating agents such as (3-aminopropyl...

PURPOSE The aim of this study was an experimental evaluation of the effectiveness of demineralized bone matrix (DBM) and collagenated heterologous bone graft (CHBG) used alone or in combination with platelet-rich fibrin on bone healing in sinus floor augmentation procedures. MATERIALS AND METHODS In this study, 36 New Zealand rabbits were used. The bilateral sinus elevation was performed, and...

The repair of bone defects that result from periodontal diseases remains a clinical challenge for periodontal therapy. β-tricalcium phosphate (β-TCP) ceramics are biodegradable inorganic bone substitutes with inorganic components that are similar to those of bone. Demineralized bone matrix (DBM) is an acid-extracted organic matrix derived from bone sources that consists of the collagen and matr...

INTRODUCTION: Bone fusion, such as in spinal surgeries, may be accelerated through the use of a bone graft substitute (BGS). While autograft was considered the gold standard of treatment, it can be undesirable for use by surgeons due to donor site morbidity and limited availability. As an alternate method of treatment, human allograft Demineralized Bone Matrix (DBM) can be used by surgeons eith...

The purpose of this study was to compare the osteogenic potential of a synthetic and a demineralized bone matrix (DBM) putty using a cranial defect model in New Zealand white rabbits. Paired, bilateral critical-size defects (10 mm) were prepared in the frontal bones of 12 rabbits and filled with either OsteoSelect DBM Putty or NovaBone calcium-phosphosilicate putty. At days 43 and 91, 6 rabbits...

The diamondback moth (DBM), Plutella xylostella (L.), costs the Chinese economy US$0.77 billion annually, and considerable research has focused on its biology, ecology, and management. Much of this research has been published locally and is inaccessible outside China. Since 1990 Brassica vegetable production has increased 20-fold and production practices have intensified, but losses continue to...

Our density functional theory (DFT)/time-dependent DFT calculations for the fluoride anion sensor, 5,7-dibromo-8-tert-butyldimethylsilyloxy-2-methylquinoline (DBM), suggested a different sensing mechanism from the experimentally proposed one (Chem. Commun., 2011, 47, 7098). Instead of the formation of fluoride-hydrogen-bond complex (DBMOHF) and excited-state proton transfer mechanism, the theor...
