Research Paper: Using Subpubic Angle in Sex Determination and Stature Estimation: An Anthropometric Study on Iranian Adult Population

Background: Pelvic bone has important sex determining features. However, anthropometric reference values vary by study population. This study aimed to determine the accuracy of subpubic angle for sex determination and height estimation in Iranian adults.Methods: In this study, the subpubic angle in the digital pelvic radiographs of 325 Iranian adults (199 males and 126 females) and their standing heights were measured. Then, the relation of subpubic angle with sex and stature was evaluated. Results: The mean(SD) subpubic angle of the studied population was 116.3 (23.7) degrees. Subpubic angle was significantly wider (P<0.001) in females [140.5(14.3) degrees] compared to males [101.0(13.3) degrees]. Moreover, we observed a significant decrease (P<0.001) in females’ subpubic angle with an increase in age. A significant reverse correlation (P<0.01) was also observed between the subpubic angle and height (r=0.416). Conclusion: This study showed that the mean subpubic angle in Iranian adults is different from the average in other populations. Our reference values can be used in forensic identification

The Effect of Home based Exercise on Treatment of Women with Poly Cystic Ovary Syndrome; a single-Blind Randomized Controlled Trial

Background: The most common reproductive endocrine disorder of reproductive age women is a Poly cystic ovary syndrome (PCOS) Metabolic syndrome has been more reported in patients with PCOS in comparison to general population. Few investigations have been performed to evaluate the independent effect of exercise on biochemical and clinical symptoms of patients with PCOS. The aim of the study was to find the effect of home base aerobic-strengthening exercises on anthropometric and hormonal variables of patients with PCOS.MaterialsandMethods:In this randomized controlled trial twenty women in the exercise group performed aerobic, strengthening exercises; the other 20 participants in the control group were advised to continue their previous physical activity pattern. Blood pressure, Waist to Hip ratio (WHR), BMI along with hormonal variables(including insulin related factors, sexual hormones and inflammatory factors) were assessed at baselineand after the 12 week intervention).Results:16patients in the exercise group and 14 patients in control group finished the study. TheWHR (p<0.001) along with the blood level of insulin (p=0.016), FBS (p=0.044), Prolactine (p=0.022) and hsCRP (p=0.035) and HOMA index (p=0.009) were decreased significantly in the exercise group compared with the control group. No significant differences were found in lipid profile and sexual hormones between groups at the end of the study.Conclusion:We can conclude that 12 weeks combined aerobic-strengthening exercise program in women with poly cystic ovary syndrome can lead to a reduction of waist to hip ratio (WHR) and some cardiovascular risk factors (including insulin, FBS, HOMA index and HsCRP) along with an increase of prolactine level in these patients

Study of Pluto's Atmosphere Based on 2020 Stellar Occultation Light Curve Results

On 6 Jun 2020, Pluto's stellar occultation was successfully observed at a ground-based observatory and Pluto's atmospheric parameters were investigated. We used an atmospheric model of Pluto (DO15), assuming a spherical and transparent pure N2 atmosphere. Using ray-tracing code the stellar occultation light curve was satisfactorily fitted to this model. We found that Pluto's atmospheric pressure at the reference radius of 1215 km is 6.72+_0.21 {\mu}bar. Our estimated pressure shows a continuation of the increasing pressure studied in 2016 consistent with a seasonal volatile transport model. We concluded that the N2 condensation processes in the Sputnik Planitia glacier are increasing due to the heating of the N2 ice in this basin. This study's result was shown on the diagram of the annual evolution of atmospheric pressure.Comment: 4 figures, 2 table

The diapriid genus, Miota Foerster (Hymenoptera: Diapriidae) is discovered from the first time from the Middle East area, represented by four species in Iran. The specimens were collected using Malaise traps during 2011-2018 in northern Iran. Four newly recorded species were Miota fungorum (Kieffer, 1910), M. monilicornis (Kieffer, 1910), M. polita (Thomson, 1858) and M. thomsoni Wall, 1998. Diagnostic characters, illustrations, geographical distributions, and a key to Iranian species are provided

Comparison of the Effectiveness of Pharmacological and Non-Pharmacological Methods in Reducing the Pain of Retinopathy of Prematurity Examination

Background: Retinopathy of prematurity (ROP) is one of the common complications in premature neonates. ROP examination is one of the most important examinations for premature babies, which is associated with pain and can be very annoying. This study aimed to compare the effectiveness of pharmacological and non-pharmacological methods in reducing the pain of ROP examination. Materials and Methods: This study was conducted as a double-blind, randomized control trial on 300 ROP examinations of patients who were hospitalized in the NICU department of Mahdieh Hospital in Tehran. The neonates were randomly selected into three groups, and ketamine 2mg/kg nasally, fentanyl two µg/kg nasally10minutes before an examination, and acetaminophen 2drop/kg orally 30 minutes before each examination were given to each neonate as two pharmacological groups. In the non-pharmacological group, infants received saddling-pacifier oral sucrose 25% 0.5cc 2 minutes before examination. Pain was assessed based on PIPP (premature infant pain index). Results: The amount of pain after using oral sucrose was significantly lower than the ketamine-acetaminophen (P-value=0.011) and fentanyl-acetaminophen (P-value=0.027) groups, but there was not a statistically significant difference between the two groups of ketamine-acetaminophen and fentanyl-acetaminophen (P-value=0.953). The hypoxia was more prevalent in the ketamine-acetaminophen group (18.8%), and the least hypoxia occurred in the oral sucrose treatment group (7%) (P-value=0.028). Conclusion: It is concluded that the effect of non-pharmacological drugs is greater than pharmacological drugs in reducing the pain of neonates during ROP examination. The effect of oral sucrose in reducing pain was more significant than ketamine-acetaminophen and fentanyl-acetaminophen. However, there was no significant difference between the two groups of ketamine-acetaminophen and fentanyl-acetaminophen

Research Paper: Sex Determination Based on Radiographic Examination of Metatarsal Bones in Iranian Population

Background: In forensic medicine, sex can be determined by studying human skeletal remains. This study aimed to evaluate the reliability of metatarsal bones in sex determination in Iranian population. Methods: A total of 184 healthy individuals (103 males and 81 females) were enrolled in the study. The sample was divided into three age groups: 20-34, 35-49, and ≥50 years. The length, width, length to width ratio (L/W), and length by width (L×W) product of sample’s right foot metatarsal bones were measured using their radiographic images.Results: The differences of length, width, L/W ratio, and L×W between two sexes were significant in all age groups (P<0.001). First metatarsal L×W had sensitivity and specificity of 85.4% and 88.8%, respectively, but the mean total L×W value of metatarsal bones had sensitivity and specificity of 94.2% and 78%, respectively. Conclusion: The first and the mean L×W values of all metatarsal bones had the highest accuracy for discriminating sexes (86.9% and 85.2%). The first metatarsal width and mean width of all metatarsal bones had an accuracy of 82.6% and 84.2%, respectively. In forensic medicine, these indexes can be used for sex-differentiation

BVRI photometric observations, light curve solutions and orbital period analysis of BF Pav

A new ephemeris, period change analysis and light curve modeling of the W UMa-type eclipsing binary BF Pav are presented in this study. Light curves of the system taken in BVRI filters from two observatories, in Australia and Argentina, were modeled using the Wilson-Devinney code. The results of this analysis demonstrate that BF Pav is a contact binary system with a photometric mass ratio q = 1.460 ± 0.014, a fillout factor f = 12.5%, an inclination of 87.97 ± 0.45 deg and a cold spot on the secondary component. By applying the distance modulus formula, the distance of BF Pav was calculated to be d = 268 ± 18 pc which is in good agreement with the Gaia EDR3 distance. We obtain an orbital period increase at a rate of 0.142 s century−1 due to a quadratic trend in the O − C diagram. Also, an alternative sudden period jump probably occurred which could be interpreted as a rapid mass transfer from the lower mass star to its companion of about ∆M = 2.45×10−6 M. Furthermore, there is an oscillatory behavior with a period of 18.3 ± 0.3 yr. Since BF Pav does not seem to have significant magnetic activity, this behavior could be interpreted as the light-time effect caused by an undetected third body in this system. In this case, the probability for the third body to be a low mass star with M ≥ 0.075 M or a brown dwarf is 5.4% and 94.6% respectively. If we assume i0 = 90◦, a3 = 8.04 ± 0.33 AU. The mass of the secondary component was also determined following two different methods which result close to each other.Fil: Poro, Atila.
