Studies on the Mechanism of the Mechanical Enlargement of Root Canals

The Journal of Nihon University School of Dentistry, 1965
As the consumption of reamers is much greater than that of files in Japan [1], it can be safely assumed that most dental clinicians use some kind of reamer for the purpose of root canal enlargement in their daily practice.In his survey on 659 instruments fractured in root canal HIGAKI [2] reported 592 of them to be reamers with a percentage as high as ...

“We Cannot Talk as a Family”: Complexities of Survivorship Communication Among Hispanic/Latino Young Adult Survivors of Childhood Cancer, Parents, and Clinicians

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Young adult childhood cancer survivors (YA‐CCS) have an increased risk of treatment‐related health complications throughout their lives. Lifelong survivorship care is recommended, yet many YA‐CCS experience disruptions in care during pediatric‐to‐adult transitions and do not receive recommended survivorship care.

Identifying Patterns of Hospitalizations Among Childhood Cancer Survivors: A Population‐Based Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Childhood cancer survivors (CCSs) experience more hospitalizations than the general population. We aimed to identify distinct hospitalization patterns among Queensland CCSs and the associated characteristics. Methods Cases (aged ≤14 years) diagnosed between 1995 and 2019 while residents of Queensland were identified through the ...

Quantum-Mechanical Study on the Catalytic Mechanism of Alkaline Phosphatases

Journal of Chemical Information and Modeling, 2017
Alkaline phosphatases (APs) catalyze the hydrolysis and transphosphorylation of phosphate monoesters. The catalytic mechanism was examined by quantum-mechanical calculations using an active-site model based on the X-ray crystal structure of the human placental AP.

Laser etching effect and enhanced chemical degradation of epoxy resin in dry-type transformer windings

Materials Research Express
Dry-type transformers are essential power equipment components. Traditional disposal methods for their windings, such as mechanical destruction, landfill, and incineration, face limitations in terms of environmental sustainability and degradation ...

Classical Complement Pathway Inhibition in a Pediatric Patient With Refractory Immune Thrombocytopenia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric refractory immune thrombocytopenia (rITP) is generally characterized by persistent thrombocytopenia and failure to achieve a sustained response to multiple standard therapies. We report a 4‐year‐old female with congenital tufting enteropathy, post‐intestinal transplant patient on immunosuppressants, who developed severe rITP ...

Structural analysis of a third-class ten-link mechanism with two complex links

Trudy Odesskogo Politehničeskogo Universiteta
The basis of a technological machine is a mechanism whose main task is to convert the predetermined mechanical motion of the moving link of the initial mechanism into the motion of the driven link required to perform a technological operation, with the ...

An efficient synthesis of novel triazoles incorporating barbituric motifs via [3+2] cycloaddition reaction: An experimental and theoretical study [PDF]

Journal of the Serbian Chemical Society, 2018
In this work, the synthesis of novel triazole derivatives with barbituric motifs in good yields is described. The alkyne was prepared through the Knoevenagel reaction of barbituric derivatives with ortho and para O-propargylated hydroxybenzaldehyde.
