This paper reviews recent research on the application of an engineered cementitious composite (ECC) as overlay in the repair of deteriorated concrete structures. ECC is an ultra-ductile fiber reinforced cement based composite, that has metal-like features when loaded in tension. The uniaxial tensile stress-strain curve shows a ‘yield’ point, followed by strain-hardening up to several percent st...
Extracorporeal circulation (ECC) is necessary for conventional cardiac surgery and life support, but it often triggers systemic inflammation that can significantly damage tissue. Studies of ECC have been limited to large animals because of the complexity of the surgical procedures involved, which has hampered detailed understanding of ECC-induced injury. Here we describe a minimally invasive mo...
OBJECTIVE A genetic component in early childhood caries (ECC) is theorized, but no genome-wide investigations of ECC have been conducted. This pilot study is part of a long-term research program aimed to: (1) determine the proportion of ECC variance attributable to the human genome and (2) identify ECC-associated genetic loci. METHODS The study's community-based sample comprised 212 children ...
BACKGROUND Early childhood caries (ECC) is a marker of social inequalities worldwide because disadvantaged children are more likely to develop caries than their peers. This study aimed to define the ECC prevalence among children living in French-speaking Switzerland, where data on this topic were scarce, and to assess whether ECC was an early marker of social inequalities in this country. MET...
Purpose. The purpose of this study was to compare the effects of load and intensity of effort-matched concentric and eccentric knee extension training on isometric strength. Methods. Unilateral isometric torque was measured using a MedX knee extension after which eleven recreationally trained females performed both concentric-only (CONC) and eccentric-only (ECC) unilateral knee extension exerci...
An engineered cementitious composite (ECC) suitable for wet-mixture shotcreting (sprayable ECC) in the fresh state, while maintaining tensile strain-hardening behavior in the hardened state, has been developed by employing a parallel control of micro-mechanics-and rheology-based design. In the development concept of sprayable ECC, micromechanics is adopted to properly select the matrix, fiber, ...
BACKGROUND Early childhood caries (ECC) is an aggressive condition that can affect teeth of young children. This study aimed to evaluate genotypic diversity and phenotypic traits of S. mutans isolated from dental biofilms of children with different caries status in comparison with caries free (CF) children. METHODS Streptococcus mutans strains were isolated from supragingival biofilm samples ...
INTRODUCTION Concentric (CON) and eccentric (ECC) contractions may involve different mechanisms related to changes in sarcolemma status and the consequent alteration of action potential transmission along muscle fibers. METHODS Muscle conduction velocity (CV), surface electromyography signal (sEMG), muscle quality, and blood lactate concentrations were analyzed during CON and ECC actions. R...
Background and purpose: Severe early childhood caries (S-ECC) are amongst the major problems of oral health in children. The purpose of this study was to determine any relationship between S-ECC and body mass index (BMI) in children (2-4 years of age). Materials and methods: In this case-control study, 300 S-EEC infected and 300 S-ECC free children were randomly selected from Tehran kinderga...
OBJECTIVE To estimate the diagnostic yield of endocervical curettage (ECC) when performed as part of a colposcopic procedure in the multicenter ASCUS-LSIL Triage Study (ALTS), a randomized trial of management strategies for women with equivocal or mildly abnormal cytology. METHODS A total of 1,119 women in ALTS had colposcopic examinations that included an ECC performed at the discretion of t...
