STATEMENT OF PROBLEM Root surface contamination or infection can potentially change the consequences of regenerative periodontal therapies and therefore the modification and disinfection of the contaminated root surfaces are necessary. OBJECTIVES This study aimed to compare the surface characteristics of the extracted human teeth after exposure to four root conditioners in different time peri...

To determine the effect on new connective tissue attachment of citric acid conditioning and fibronectin-laminin application in treating naturally occurring periodontitis, all 4 quadrants in each of 2 Beagle dogs were used. Each quadrant included: P2, P3, P4, and M1 teeth. 2 treatment modalities were employed and comparatively analyzed for differences in histological healing respponses at 120 da...

Abstract Aims Drought events can alter the composition of plant and soil communities, are becoming increasingly common severe due to climate change. However, how droughts affect plant-soil feedbacks is still poorly understood. Plants accumulate species-specific rhizosphere may have varying impacts across species biota. We therefore tested hypothesis that drought alters differently among closely...

The evolutionarily ancient α/β hydrolase DWARF14-LIKE (D14L) is indispensable for the perception of beneficial arbuscular mycorrhizal (AM) fungi in rhizosphere, and a range developmental processes. Variants D14L recognise natural strigolactones smoke constituent karrikin, both classified as butenolides, additional unknown ligand(s), critical symbiosis development. Recent advances understanding ...

introduction: allogeneic hematopoietic cell transplantation (hsct) is the only therapeutic modality capable of correcting the hematologic manifestations of fanconi anemia (fa). the development  of well  tolerated,  immunosuppressive  conditioning  regimens  for fa patients  undergoing hsct has proven to be a rather challenging task for hematologists. methods: we analyzed the outcome of 30 fa pa...

objective(s) single injection of naloxone, a selective antagonist of morphine, prior to the drug conditioning testing was used to investigate on morphine dependence. materials and methods conditioning to morphine (2.5-10 mg/kg, s.c.) was established in adult male wistar rats (weighing 200-250 g) using an unbiased procedure. nitric oxide agents were microinjected into the central amygdala prior ...

sludge drying bed is preferred to mechanical methods due to the need for very simple technology. due to restriction of natural dewatering, we tried to eliminate some of these limitations by the tests and studies of assumptions. in this study, the effect of hydrostatic suction and sludge chemical conditioning has been studied in the natural sludge dewatering optimization. at first, hydrostatic s...

today air conditioning systems have been considered by all people as one of welfarerequirements in buildings and closed environments. since a considerable part of energy lossoccurs in ordinary modern systems, new strategies and solutions are developed in the field inorder to save amount of energy consumption and observe environmental considerations. fuzzycontrol is one of these methods which pr...

the first and second laws of thermodynamics have been employed to evaluate energy and exergetic efficiency of the single effect absorption chiller which is used for air conditioning purpose. the performance analysis has been carried out by developing a computer program in ees and modeling the chiller and its components. to evaluate entropy of the water/lithium bromide solution at any point, an ...
