Recent tendencies in concrete technology have been towards to high- performance concrete with a low water-cement ratio. However, high performance concretes have some problems. One of the problems is early-age cracking due to autogenous shrinkage. This study presents the results of an experimental investigation carried out to evaluate the autogenous shrinkage of high-strength concrete. Accordi...

The maintenance and repair of concrete infrastructure covers an increasing portion the annual construction budget. For this reason, self-healing cementitious materials have been investigated thoroughly in literature. One way to achieve effective composite is by promoting their inherent ability through inclusion superabsorbent polymers (SAPs). Thanks large absorption capacity upon contact with w...

The main aim of this study was to perform an integrative review on the enhanced bone healing by combining a flowable (injectable) platelet-rich fibrin (PRF) and graft porous materials. A bibliographical search carried out several databases (PubMed, Embase, Cochrane, Scopus, Web Science) for relevant studies combined effect substitutes healing. chemical, biologic, physical properties PRF with bi...

The effects of alumina nano-fibres are investigated in this paper on the mechanical performance Ultra High Performance Fibre Reinforced Cementitious Concrete and their efficacy enhancing durability cementitious composite when exposed to extremely aggressive conditions, with main reference stimulated autogenous crack sealing self-healing capacity. A tailored characterization flexural tensile beh...

PURPOSE The aim of the present study was to evaluate retrospectively both the results of using a mixture of bovine hydroxyapatite (BHA) and fibrin glue as the only grafting material in the floor of the maxillary sinus and the outcome of nonsubmerged implants placed later. MATERIALS AND METHODS A total of 50 consecutive patients (71 maxillary sinuses) were augmented with a mixture of BHA and f...

OBJECTIVE The adipose tissue represents an important reservoir of stem cells. There are few studies in the literature with which to histologically evaluate whether or not the adipose tissue graft is really a safe option to achieve bone repair. This study histologically analyzed the effect of fragmented autogenous adipose tissue grafts on bone healing in surgically created, critical-size defects...

INTRODUCTION For access-challenged patients with bilateral upper extremity central venous stenosis, solutions include the Hemodialysis Reliable Outflow (HeRO) device or an autogenous AV fistula in the lower limb. We evaluated HeRO grafts and transpositions of the femoral vein in maintaining primary and secondary patency. METHODS We retrospectively analyzed 40 patients with a HeRO device and 1...

BACKGROUND: Dental disease, trauma and maxillofacial surgeries can cause alveolar bone defects. Among different kinds of treatment, autogenous bone grafts is accepted as a golden standard. On the other hand, because of limitation of treatment with autogenous bone grafts, osteogenic cells derived from stem cells are suggested. OBJECTIVES: The aim of this study was to compare the mean density of ...
