the relationship between congenital heart disease (chd) and growth retardation is well documented. we investigated the growth condition of iranian children with several types of congenital heart disease (chd) and compared it with worldwide researches. growth condition was investigated in 469 patients with important chd aged from 1 month to 18 years. the patients were divided into two groups; in...

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...

In focus of this report are the mechanisms formation, propagation, and interaction growth defects in heteroepitaxial diamond films along with their impact on optical emission properties N- Si-vacancy (NV SiV) color centers. Here, we analyze discuss incoherent grain boundaries (IGBs) extended a nitrogen- boron-doped heterodiamond nucleated grown Ir(001) via bias-enhanced nucleation chemical vapo...

Primary growth hormone (GH) resistance describes growth failure in the presence of normal, or even elevated, GH secretion. In its classic form, the phenotype is identical to that of GH deficiency, and was originally described in association with defects of the GH receptor. With increasing understanding of the GH-insulin-like growth factor (IGF) axis, it has become apparent that GH resistance ca...

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 ...

Longitudinal growth is primarily influenced by the GH-IGF-I axis, which is a mixed endocrine-paracrine-autocrine system. Further, classical hormones such as thyroxine, glucocorticosteroids and sex steroids play a role, as well as primarily paracrine systems. In the GH-IGF-I axis, seven disorders can be differentiated: (1) GH deficiency; (2) GHR defects; (3) defects in the GH signal transduction...

We study stripe formation in two-dimensional systems under directional quenching a phase-diffusion approximation including nonadiabatic boundary effects. find through simple traveling waves for all angles relative to the line using an analytic continuation procedure. also present comprehensive analytical asymptotic formulas limiting cases of small and large as well rates. Of particular interest...

background: alcohol is a potent teratogen and alcohol use in pregnancy and the periconception period can cause many complications in mother, fetus and neonate.  discussion: alcohol in the mother's blood passes through the placenta to the baby through the umbilical cord. drinking alcohol during pregnancy can cause miscarriage, stillbirth, and a range of lifelong disorders. alcohol-related birth ...
