conclusions both l-prp and l-prf could be used to effectively promote the healing of articular cartilage defects of the knee. results mean macroscopic scores of the treated defects were higher than the controls at all sampling times with significant differences (p < 0.05) observed between l-prf treated and control defects (10.13 vs. 8.37) and l-prp treated and control defects (10 vs. 8.5) at 4 ...

Several deficient steel structural members require to be strengthened all over the world. In this article, horizontal defects were generated at three locations (top, middle, and bottom) on the middle element and the middle of the side element. Consequently, the effects of the location of such defects on axial behavior of Carbon Fiber Reinforced Polymer (CFRP) strengthened steel Square Hollow Se...

aortopulmonary window (apw) is a rare congenital malformation. it results from an incomplete division between the ascending aorta and the pulmonary artery. we describe a 26-year-old male, who presented with a grade ii exertional dyspnea and palpitations. echocardiography revealed an apw with an ascending aorta aneurysm. he underwent surgery under cardiopulmonary bypass without aortic cross-clam...

abstract objective neural tube defects including anencephaly, encephalocele, and spina bifida are major congenital malformations with multifactorial etiology, and with a great variation in their prevalence in different populations. the study on the prevalence of these malformations may be helpful in planning strategies for their prevention. the aim of this epidemiologic descriptive study was to...

statement of problem: there are limited histomorphometric studies on biologic efficacy of high density tetrafluoroethylen (d-ptfe) membrane. objectives: to investigate the healing of surgically induced grade ii furcation defects in dogs following the use of dense polytetrafluoroethylene as the barrier membrane and to compare the results with the contra lateral control teeth without the applicat...

in the present study, the effects of growth defects and chromium content loss on the degradation of corrosion andpassivation of cathodic arc evaporation (cae-pvd) of stainless steel coating were investigated in 2 m sulphuricacid solution. eds analysis indicated that the micro-particles were obtained during the coating growth. in addition,it was detected that the growth defects had poor adhesion...

abstract a 49-year-old man with lutembacher&apos;s syndrome associated with frontal meningioma referred to our hospital. he also suffered from exertional dyspnea. transthoracic echocardiography demonstrated mitral valve area of 1.48 cm2, moderate mitral stenosis, and left atrial dimension (lad) of 5.6 cm with no clot. tee revealed severe mitral stenosis, mitral valve area of 1.05 cm2 with wilki...

there is a number of syndromes, associated with proptosis, micrognathia, low-set ear and chest deformity. herein, we report a 9-year-old female with such phenotype who was presented with a vaginal neuroma. the result of karyotype showed 47xx, with extra marker chromosome 22. although such a manifestation had not been reported in the literature, it should be considered as a very rare manifestati...

background:  levels of anti-inflammatory cytokines in blood have a positive relationship with congenital heart disease (chd). we sought to assess the difference in serum cytokines levels between children with and without chd.  methods:  we recruited 60 patients with chd and 30 healthy children, from 2013 to 2014. patients with primary pulmonary hypertension; metabolic diseases; renal, endocrine...

this study aimed to compare the efficacy of mta and cem cement in class ii furcation defects in human mandibular molars.forty furcation defects were treated in 16 patients with chronic periodontitis. the clinical parameters of probing depth (pd), vertical and horizontal clinical attachment levels (vcal and hcal), open vertical and horizontal furcation depths (ovfd and ohfd), and gingival margin...
