A serine protease with preference for fibrin protein was purified and characterized from B.amyloliquefaciens MCC2606, isolated from dosa batter. The protease was purified using ammonium sulphate precipitation, ion-exchange and gel filtration chromatography. The degradation activity of the protease towards the fibrin was significantly higher compared with other protein substrates in the study. The molecular weight of the CFR15-protease was estimated to be 32 kDa based on SDS-PAGE. The purified enzyme exhibited both fibrinolytic and fibrinogenolytic activity...

Clinicians commonly contend that the screw-retained, implant-supported fixed dental prosthesis (FDP) should be fabricated with all nonengaging abutments to allow for the inherent nonparallelism of the implants and the inability of the abutment connections to draw together during insertion and removal. The problem with a fully nonengaging FDP is difficulty in handling and more strain on the abutment screws, ultimately leading to increased rates of breakage and loosening. The hemi-engaging FDP design regains much of the advantage afforded by the internal connection and improves prosthetic handing both clinically and in the laboratory...

The use of the direct fiber-reinforced fixed dental prosthesis (FDP) restorative technique presented in this article will result in an ideal restoration considering both esthetics and function in a single appointment. Although indirect techniques are available and may be used, they are time-consuming, resulting in higher cost; therefore, a simplified approach combining a prebonded fiber-reinforced mesh with a sculptable micro-hybrid composite will deliver an acceptable esthetic result with proper function.

Cases of Clostridium perfringens septicemia, such as liver abscess, often develop a rapidly progressive intravascular hemolysis and coagulation; the mortality rate with current standard care including antibiotics and surgery is high. Herein, we firstly investigated the effects of gas gangrene antitoxin (GGA) (antitoxin against C. perfringens) and recombinant human soluble thrombomodulin (rTM) on the hemolysis, coagulation status, inflammatory process, and mortality in α-toxin-treated rats. Male 11-week-old Sprague Dawley rats were randomly divided into five groups: control group, α-toxin group, GGA group, rTM group, and combined GGA and rTM (combination group)...

Breeding strawberry (Fragaria x ananassa) with enhanced fruit flavour is one of the top breeding goals of many strawberry-producing countries. Although several genes involved in the biosynthetic pathways of key aroma compounds have been identified, the development and application of molecular markers associated with fruit flavour remain limited. This study aims to identify molecular markers closely linked to genes controlling strawberry aroma. A purpose-built Subtracted Diversity Array (SDA) known as Fragaria Discovery Panel (FDP) was used for marker screening...

Children's drawings have previously been found to reflect their representations of family relationships. The present study examined whether evidence-based parent training for child conduct problems impacts on representations of family functioning using the Family Drawing Paradigm (FDP). N = 53 clinic-referred children (aged 3-15) with conduct problems and their families were assessed pre-treatment and at 6-month follow-up on a modified version of the FDP. Analyses of changes in the FDP revealed improvements in family functioning but not tone of language (as indicated by written descriptors) following treatment...

In spite of numerous studies on the involvement of fibrinogen in transendothelial migration of leukocytes and thereby inflammation, there is still no clear understanding of which fibrin(ogen) species can stimulate leukocyte transmigration. Although we have previously proposed that interaction of fibrin with the VLDL receptor (VLDLR) promotes leukocyte transmigration, there is no direct experimental evidence for the involvement of fibrin in this process. To address these questions, we performed systematic studies of interaction of VLDLR with fibrinogen, fibrin, and their isolated recombinant BβN- and βN-domains, respectively, and the effect of various fibrin(ogen) species on transendothelial migration of leukocytes...

OBJECTIVES: The inferior vena cava (IVC) diameter is associated with shock and increased mortality in trauma patients. However, there are no reports examining the association between the IVC diameter and massive transfusion (MT) requirements in trauma patients. The aim of this study was to evaluate the association between IVC diameter and MT requirements in patients with blunt trauma. METHODS: We retrospectively reviewed all patients who were consecutively hospitalized with blunt trauma (Injury Severity Score [ISS] ≥16) between from November 1, 2011 to March 30, 2016...

Suboptimal adaptation of fixed dental prostheses (FDPs) can lead to technical and biological complications. It is unclear if the computer-aided design/computer-aided manufacturing (CAD/CAM) technique improves adaptation of FDPs compared with FDPs made using the lost-wax and metal casting technique. Three-unit FDPs were manufactured by CAD/CAM based on digital impression of a typodont model. The FDPs were made from one of five materials: pre-sintered zirconium dioxide; hot isostatic pressed zirconium dioxide; lithium disilicate glass-ceramic; milled cobalt-chromium; and laser-sintered cobalt-chromium...
