introduction: langerhans cell histiocytosis (lch) is a rare disease characterized by clonal prolifera-tion of histiocytosis in different tissues. permanent consequences (pc) described among subjects with langerhans cell histiocytosis (lch).in this study we report the prevalence of permanent sequel among long – term survivors of lch in our center. methods: we had 30 cases of lch from 1989 – 2001...
Search results for nucleon decays p→e^{+}X, p→μ^{+}X, n→νγ (where X is an invisible, massless particle) as well as dinucleon decays np→e^{+}ν, np→μ^{+}ν, and np→τ^{+}ν in the Super-Kamiokande experiment are presented. Using single-ring data from an exposure of 273.4 kton·yr, a search for these decays yields a result consistent with no signal. Accordingly, lower limits on the partial lifetimes...
the aim of this study was to examine the effect of 12 weeks of concurrent training on rbp4 andinsulin resistance levels in obese middle-age men. for this purpose, 20 obese middle-age men voluntarily participated in this study and were assigned to concurrent training group (n=10, mean age 51.2 ± 2.25 yr and bmi 31.44 ± 0.81 kg/m²) and control group (n=10, mean age 50.3 ± 2.11 yr and bmi 30.32 ± ...
conclusions the vitamin d levels of children aged more than 2 years are lower than those of children aged less than 2 years. thus, prescribing vitamin d-containing supplements in children older than 2 years may be beneficial. results the final study consisted of 286 children, 140 males and 146 females, with a mean age of 4.46 ± 2.82 yr. of these, 218 (76.22%) children, with a mean age of 5.09 ±...
the present research aimed to study the growth and reproductive parameters of common kilka clupeonella caspia in southern caspian sea in 2010. after measuring the length and weight of 3774 samples, they were dissected, sex determined and female gonads were weighed. sexual maturity classification was carried out based on six stages. age was determined using sagitta otoliths. length-weight relati...
Visual fixation of a small, stationary target was measured in 12 young observers (mean age = 22 yr) and in 12 older observers (mean age = 70 yr). The two groups' fixation behavior did not differ on various dimensions of fixation stability: mean fixation area, intra-subject variability, or changes in fixation over successive test periods. Connections between these results and age-related changes...
background: a growing body of investigations demonstrated the essence role of zinc on growing and maintaining bone tis sue .the idea that zinc could enhance bone content and adjourn or prevent osteoporosis in men, has been experimented as a hy pothesis. methods: six hundred healthy men (age 20-69 yr) through iranian multicenter osteoporosis study (imos) which is a na tional project running in 5...
C lassically, the normal chronological age for pubertal onset is between 8 and 13 years in girls and 9 and 14 years in boys based on data from epidemiological studies from the 60’s (1). However, the age limit for pubertal timing is still a challenge (2,3). It is well known that puberty is a complex and multi factorial process that involves genetic, metabolic, socio economic, nutritional and eth...
This study aimed to clarify the role of blood lead level (Pb-B) as one of the cardiovascular risk factors. To evaluate the cardiovascular risk the second derivative finger photoplethysmogram (SDPTG) was used. The subjects comprised of 420 male bus drivers in Thailand. The subjects' age ranged from 20 to 60 yr. Mean age (+/- standard deviation) were 41.6 (+/- 7.7) yr. Mean working years was 8.8 ...
Backgrounds: Envenomation is common in Asia including Iran that induces morbidity and mortality. This study investigated the epidemiological characteristics of cases with snake, spider and scorpion bites. Methods: In this cross-sectional design, epidemiologic data of admitted cases to the Toxicology Department of Imam Reza Hospital of Mashhad, Iran were analyzed across a 7-yr period, from 2004...
