Fatemeh Nikkhou,Saeid Hasanzadeh,Gholamali Afrooz
Audiology , 2012,
Abstract: Background and Aim: In different language approaches, reading is considered as a major skill. Language skills comprising listening, speaking, reading and writing are completely interlinked with each other. Thus, providing active application of listening and speaking skills, children will learn reading and writing skills easily. The aim of this research was to compare reading skills of hearing-loss students studying at exceptional schools with normal students of different degrees.Methods: The research was conducted post-traumatically using standardized 2006 PIRLS test. 80 students in fifth grade of exceptional primary schools, and first and fourth grade of exceptional high schools in Tehran City who had severe and or profound hearing loss were randomly selected along with 80 normal students in ordinary schools who were selected using available sampling method.Results: There were significant differences between reading comprehension of hearing-loss and normal students of all three grades (p<0.001). Reading comprehension in female students was significantly higher than the male ones (p<0.001). There were not any significant differences in mean reading comprehension scores of hearing-loss students in different grades which demonstrate that their reading skills had not developed in tandem with their age and school educations.Conclusion: This study shows that one of the significant concerns regarding hearing-loss students is their reading comprehension ability. Considering reading ability as one of the most important acquisitive abilities which students learn at school, evaluation of reading skills of hearing loss students as well as recognition of their strengths and weaknesses in this field is indispensable.

Abstract: Background and Aim: Low weight at birth is one of the main health indexes in evaluating pregnancy period care, and recognizing its related factors is very important. The aim of this study was a comparison of pregnancy age, height, the distance between two pregnancies, gaining weight during pregnancy, economical condition, nutrition, general health of the mothers with low and normal birth weight. Materials and Methods: The research method was casual-comparative conducted as field-work. From all newborns born since (Jan 2008 to Nov 2009) 168 low birth weight babies with their mother and 157 newborns with normal weight from 20 maternity center at Guilan province were randomly selected. Mothers filled general health questionnaire with the reliability of 0.82. The data were analyzed using SPSS Software. Results: There was a significant difference among mothers (case and control ) in terms of pregnancy age, height ,distance between two pregnancies, increasing weight during pregnancy, economical condition, nutrition condition and general health (mental), (p 0.01). Conclusion: Various factors affected newborns weight at birth. Therefore, decreasing the rate of low weight will be one of the main social health indexes requiring cooperation of counter- groups and different organizations such as the Ministry of Health and treatment, psychotherapy, counseling centers and radio/television.
Android Shape Independent of Aerobic Fitness: A Risk Factor for Low Bone Mineral Content in Overweight and Obese Latina Women

Clinical Medicine Insights: Women's Health , 2012, DOI: 10.4137/CMWH.S10979
Abstract: Objective: The link between central adiposity and osteopenia has not been extensively studied in Latina women. In particular, the association between abdominal weight and bone mineral content (BMC) and bone mineral density (BMD), independent of total weight and aerobic capacity, remains uncertain, especially in overweight and obese individuals. Methods: Trunk weight, total body fat mass, fat-free mass, BMC, and BMD of 33 premenopausal Latina women age 22 to 51 years from Los Angeles, California were measured using dual-energy X-ray absorptiometry (DXA). Waist circumference (WC) was measured without clothing at the smallest circumference of the torso. Peak aerobic capacity (peak VO2) was determined by treadmill ergometry with direct measurement of oxygen consumption. Results: Partial correlations controlling for total body fat mass, fat-free mass, and peak VO2 revealed a significant inverse relationship between BMC and WC (r = -0.54, P , 0.05) but not between BMD and WC (r = -0.18, P = 0.41). Similarly, while controlling for total body fat, fat-free mass, and peak VO2, BMC was inversely associated with trunk fat (r = -0.75, P , 0.001), with trunk lean (r = -0.61, P , 0.05) and with total trunk weight (r = -0.75, P , 0.001); results were non-significant for BMD. When these analyses were repeated separately in overweight (n = 10) versus in the obese (n = 18) women, inverse relationships between BMC and trunk fat as well as between BMC and total trunk weight became stronger in the obese compared with the overweight women. Conclusion: Although general obesity may prevent osteoporosis, these findings suggest that abdominal obesity (ie, trunk weight) specifically and independently may adversely influence bone mass.

Pakistan Journal of Biological Sciences , 2009,
Abstract: The aim of this study is evaluation of procalcitonin role in the diagnosis of infectious and non infectious inflammation. This cross-sectional study was conducted in one hundred patients in Baqiyatallah Hospital of Iran in 2008. Patients suspected to infection were recruited to study. They were divided to four groups as: systemic inflammatory response syndrome, sepsis, sepsis syndrome and septic shock. Procalcitonin quantitative was assayed by immunoluminometric kit manufactured in Germany. Procalcitonin level was divided to four groups in <0.5 ng mL-1 compatible for SIRS, 0.5-2 ng mL-1 for sepsis and 2-10 ng mL-1 for sepsis syndrome and >10 ng mL-1 for septic shock. Data was analyzed by SPSS 13 for window software; T student test, ANOVA and Chi-square were used. In this study 53(53%) of subjects were men with mean age of 56.16 ± 19.5 years old. The diagnosis was SIRS in 36%, sepsis in 38%, sepsis syndrome in 14% and septic shock in 12% of cases. Procalcitonin level was less than 0.5 ng mL-1 in 61% and more than 10 ng mL-1 in 10% of patients. Procalcitonin level showed significant association with septic shock, positive blood culture and mental dysfunction. Ultimately this study showed that high level of procalcitonin can differentiate septic shock from SIRS and other stages of infection. Dysfunction of mental status and high level of procalcitonin can determine septic shock.

Maejo International Journal of Science and Technology , 2008,
Abstract: Oyster mushroom [Pleurotus ostreatus var. sajor caju (Fr.) Singer] was grown on five substrates: rice straw, rice straw + oilseed rape straw (75:25, 50:50, and 25:75 dw/dw), and oilseed rape straw alone. Rice straw + oilseed rape straw (25:75) and oilseed rape straw were best for fruit body production of P. ostreatus. The time to fruiting for P. ostreatus was also shorter on oilseed rape straw. Protein content of the fruit bodies obtained with oilseed rape straw was highest among all substrates. Oilseed rape straw thus appears to be a suitable substrate for oyster mushroom production.

Pakistan Journal of Biological Sciences , 2007,
Abstract: The antimicrobial activities of four different extracts (ethanol, methanol, distilled water and 2-Methylbutan-1-01) obtained from different parts of broad bean (Vicia faba L.) such as flowers, leaves, seeds and seed hulls and were tested against Bacillus subtilis, Serratia marcescens, Staphylococcus aureus, Escherichia coli, Klebsiella peneumoniua, Shigella sp. and Micrococcus pyogenes. Better antimicrobial activity was observed with the leaves of broad bean sterile distilled water extract with a zone of inhibition in between 13-32 mm. Flower and seed hull showed by Escherichia coli, Shigella sp., Bacillus subtilis, Serratia marcescens, Staphylococcus aureus and Micrococcus pyogenes a zone of inhibition in between 15-29 and 14-19 mm, respectively. Leaves, seed hulls and flowers of broad bean with ethanol extract showed by Escherichia coli a zone of inhibition in between 25-34, 15-17 and 15 mm, respectively. Flower with ethanol extract had a zone of inhibition in between 15-16 mm by Bacillus subtilis and Micrococcus pyogenes, respectively. Different parts of Broad Bean with methanol and 2-Methylbutan-1-01 extract did not shown any antimicrobial affects.

Physiology and Pharmacology , 2010,
Abstract: Introduction: Recent increase of endocrine disorders may be correlated to the increased exposure to electromagnetic fields from various instruments. Radiation leakage from microwave oven may be harmful for users. Ladies have the highest levels of contact with microwave ovens. This study was carried out to evaluate the effect of radiation leakage from microwave oven on body weight, cortisol and thyroid hormones. Methods: Radiation leakage of microwave oven was measured by RF measuring instrument. For this study, 20 adult two-month-old female mice weighing 25-28 g were randomly divided in control and test groups. Test group was exposed to 2450 MHZ microwaves produced by a microwave oven 3 times a day, 30 minutes each time. After 60 days, body weights of both groups were determined and blood was collected by heart puncture. Cortisol and thyroid levels were evaluated in serum by an RIA method. Results: radiation leakage from oven showed variation and ranged from 6.5 to 57.5 mW/cm2. Mean body weight changes in test and control groups were 0 and 4.54 grams, respectively. Cortisol (23.6 ± 2.24 vs. 13.6 ± 1.47 ng/ml) and T4 (98.4 ± 7.3 vs. 67.0 ± 5.9 nmol/L) levels were significantly increased in the test group compared to the control group, respectively. Level of T3 did not alter significantly. Conclusion: We found that microwaves leaked from oven decrease body weight and increase T4 and cortisol levels, and therefore have deleterious health effects.
