Electrophysiological Assessment of Injury to the Infra-patellar Branch(es) of the Saphenous Nerve during Anterior Cruciate Ligament Reconstruction Using Medial Hamstring Auto-grafts: Vertical versus Oblique Harvest Site Incisions

Background: It was suggested that the direction of incision for medial hamstring tendons harvesting\n influences the incidence of injury to the infrapatellar branch of the saphenous nerve\n (IPBSN), a common complication following arthroscopically-assisted anterior cruciate\n ligament reconstruction (ACLR). Objectives: The main purpose of current study was to compare the incidence of IPBSN injury between\n vertical and oblique incisions utilizing electrophysiological evaluation. Patients and Methods: There were 60 patients underwent arthroscopically-assisted ACLR assigned to two equal\n vertical or oblique incision groups, randomly. One year postoperatively, the patients\n were electrophysiologically examined to detect whether IPBSN is injured. The Lysholm\n score was completed. The patients' satisfaction with surgical outcomes determined\n utilizing visual analogue scale (VAS). Finally, two groups were compared and the effect\n of IPBSN injury on function and satisfaction was investigated. Results: The incidence of IPBSN injury was higher in the vertical group (4 patients vs. 10\n patients), but the difference was not statistically significant. The mean of Lysholm and\n VAS scores were the same. Also, the mean of Lysholm score was the same in patients with\n and without IPBSN injury. However, patients without IPBSN injury were more satisfied\n (8.9 ± 9 vs. 7.4 ± 1.1; P < 0.001). Conclusions: IPBSN injury is a common complication following arthroscopically-assisted ACLR and, if\n not significant, oblique direction of the incision is associated with decreased\n incidence of the injury. IPBSN injury has no effect on the function but because of the\n disturbance with patients' satisfaction, authors believe the oblique incision is\n preferable to avoid the nerve injury during medial hamstring tendons harvesting

Genetic relationships of Iranian coastline ship sturgeon (Acipenser nudiventris) samples and Ural population based on microsatellite DNA

Genetic relationships among 96 specimens of ship sturgeon, Acipenser nudiventris, collected from six locations along the Iranian coastline as well as 8 specimens from northern population (Ural River) were analysed by the restricted maximum likelihood method, as well as two distance analysis method (Nei's and Cavalli-Sforza's distance) of gene frequencies. We have used four SSR markers that produced three polymorphic and two monomorphic loci. Overall results showed that Iranian coastline samples form a monophyletic group (clade) which was different from the northern (Ural) samples. Iranian coastline samples are divided into two groups (clades): Anzali-Kiashahr clade and Sefidrud-Babolsar-Noushahr-Gorgan clade. Bootstrapping test showed monophyleticity of Sefidrud, Babolsar, Noushahr, Gorgan with high (Bootstrap support=93) and Anzali-Kiashahr with middle (Bootstrap support=65) confirmation. Topology of reconstructed trees was in correspondence with geographical distributions of samples

Sexual dimorphism and morphometric study of Caspian pond turtle, Mauremys caspica (Testudines : Geoemydidae) in Golestan Province, southeast of the Caspian Sea

The Caspian pond turtle, Mauremys caspica, is a terrapin belonging to family Geoemydidae. Totally, 130 specimens (67 males and 63 females) were collected manually and by net from different aquatic habitats in Golestan Province from 2016 through 2017. Morphometric characteristics such as length were measured using digital caliper and weight by electronic weighting scale. Skin of this turtle was dark olive green in color and had rows of longitudinal yellow stripes around the head and neck. Their carapace was relatively flat, the bridges between the dorsal and ventral shells were bony, and the ends of anal scutes were found to be pointed. Fingers and toes had swimming membranes. Sexes were identified using the location of vent on the tail. Sex ratios of males to females were nearly 1:1. The maximum straight carapace length (SCL2) was 80.66-230.16 (156.72 ± 42.93) and 56.96-236.84 (147.02 ± 50.76) in males and females, respectively. Ratios of SCL2 to maximum plastron length (PL2) were found to be 1.013- 1.32 (1.15 ± 0.04) in males and 1.01-1.15 (1.08 ± 0.03) in females; ratios of SCL2 to straight carapace width (SCW) were 1.24-2.60 (1.40 ± 0.16) in males and 1.20-1.47 (1.35 ± 0.07) in females; ratios of SCL2 to carapace height (CH) were 2.28-3.55 (2.79 ± 0.22) in males and 2.05-8.78 (2.87 ± 1.11) in females; ratios of SCL2 to tail length2 (TL2) were 2.33-7.59 (3.76 ± 0.91) in males and 2.34-4.78 (3.06 ± 0.62) in females. Ratios of straight width of femuro-anal suture (FASW) to anal seam length (AnSL) were 2.95–5.89 (3.78 ± 0.54) in males and 2.65-4.13 (3.23 ± 0.40) in females. The ratio of TL2 to TL1 and TL1 to RBrL are found to be the fast and simple grouping index to determine sex of the specimens

The Effect of Eight Weeks Sahrmann's Present and Virtual Corrective Exercise Program on ‎the Upper Cross Syndrome of Female Teachers During the COVID-19 Pandemic‎

Purpose:Considering the high prevalence of upper cross syndrome among teachers, it is necessary to always provide selected corrective exercises to increase productivity. One of the methods of providing corrective exercises in special conditions is virtual education. The purpose of the current research was to compare the effect of a course Sahrmann's corrective exercises at Present and virtual on the upper cross syndrome of femalee Teachers.Methods:The present study was a randomized clinical trial with a pre-test and post-test design. The number of 60 volunteer teachers who had the conditions to participate in the study according to the entry criteria were randomly divided into three groups of 20 people for present (with an average age of 45.90±3.07), virtual corrective exercises (with an average age of 43.30±4.84) and control group (with an average age of 42.70±5.11). Neck pain and disability were measured by scale questionnaire (NPDS), shoulder pain and disability by index questionnaire (SPADI), forward head angle, forward shoulder angle and uneven shoulder angle by photography method and AutoCAD software and kyphosis angle by Kyphometer. In the statistical analysis, after confirming the normality of the data, the parametric ANOVA test and in case of significance Bonferroni's post hoc test were used. \The nonparametric Kruskal-Wallis test and  U-Man-Whitney test with Bonferroni correction were used if the condition of normality has not been met.Results:The results of the research showed a significant difference between the control and two present and virtual training groups in all evaluation variables: angles of forward head, shoulder forward on the right side and left side, uneven shoulder on the right side and left side, neck pain and disability, kyphosis angle and shoulder pain and disability (p=0.001). There was a significant difference in the kyphosis angle and shoulder pain and disability variables in the comparison between the two present and virtual training groups (p=0.001). However, no significant difference was observed in other variables.Conclusion:Virtual corrective exercises using the various solutions presented achieved a result close to the present exercises. Considering the importance of teachers' health and the priority of rehabilitation goals in them, it is possible to recommend the use of virtual training in emergency cases that prevent present training

The Effects of Folic Acid Supplementation on Recurrence and Metabolic Status in Endometrial Hyperplasia: A Randomized, Double-Blind, Placebo-Controlled Trial

Abstract: Background: Data on the effects of folic acid supplementation on clinical symptoms and metabolic profiles of patients with endometrial hyperplasia (EH) are limited. This investigation was performed to evaluate the effects of folic acid supplementation on clinical symptoms and metabolic status of patients with EH. Methods: This randomized, double-blind, placebo-controlled trial was conducted among 60 women diagnosed with EH. Diagnosis of EH was made based on biopsy results. Participants were randomly allocated to 2 groups to take 5 mg/d folic acid supplements (n = 30) or placebo (n = 30) for 12 weeks. Results: After the 12-week intervention, folic acid supplementation significantly decreased fasting plasma glucose (β -3.99 mg/ dL; 95% CI, -7.39, -0.59; P = 0.02), serum insulin levels (β -2.82 µIU/mL; 95% CI, -4.86, -0.77; P = 0.008), homeostasis model assessment for insulin resistance (β -0.68; 95% CI, -1.20, -0.17; P = 0.009), triglycerides (β -16.47 mg/dL; 95% CI, -28.72, -4.22; P = 0.009) and very-low-density lipoprotein (VLDL) cholesterol (β -3.29 mg/dL; 95% CI, -5.74, -0.84; P = 0.009), and significantly increased the quantitative insulin sensitivity check index (β 0.01; 95% CI, 0.004, 0.03; P = 0.01) compared with the placebo. Additionally, folic acid intake resulted in a significant reduction in serum high sensitivity C-reactive protein (hs-CRP) (β -0.36 mg/L; 95% CI, -0.52, -0.21; P &lt; 0.001) compared with the placebo. Folic acid supplementation did not affect other metabolic parameters. Conclusion: In conclusion, we found that folic acid administration for 12 weeks to subjects with EH improved glycemic control, triglycerides, VLDL-cholesterol and hs-CRP levels, but did not influence recurrence and other metabolic profiles

Threshold Based Skin Color Classification

In this paper, we presented a new formula for skin classification. The proposed formula can overcome sensitivity to noise. Our approach was based multi-skin color Hue, Saturation, and Value color space and multi-level segmentation. Skin regions were extracted using three skin color classes, namely the Caucasoid, Mongolid and Nigroud. Moreover, in this formula, we adopted Gaussian-based weight k-NN algorithm for skin classification. The experiment result shows that the best result was achieved for Caucasoid class with 84.29 percent fmeasure

Evidence of American Martens Populating the Turtle Mountains of North Dakota

American martens (Martes americana) were native to northeastern North Dakota but were considered extirpated by the early 1800s. Although there is no historic evidence of martens occurring beyond the northeast, forested habitat potentially suitable for martens exists in the Turtle Mountains region of northcentral North Dakota and southwestern Manitoba. From 1989– 1991, the Turtle Mountain Trappers Association translocated 59 martens into the Canadian portion of the Turtle Mountains. During summer 2007, we used covered track-plates and/or remotely-triggered cameras placed at 123 survey sites distributed among 41 1-km2 grid cells (a GIS-generated layer imposed on electronic maps of the study region) to determine if martens occupied the Turtle Mountains in North Dakota. Martens were detected at 26 (21%) sites, representing 20 of the 41 sample cells (49%) widely dispersed throughout the study area. Our study provided the first evidence of martens occurring in North Dakota since the early 1800s

Analyzing utilization of biomass in combined heat and power and combined cooling, heating, and power systems

Nowadays, ever-increasing energy demands and the depletion of fossil fuels require efficient and environmentally friendly technologies for energy generation. In this context, energy systems integration makes for a very strong proposition since it results in energy saving, fuel diversification, and the supply of cleaner energy. To this end, it is of the utmost importance to realize the current developments in this field and portray the state of the art of renewable generation in integrated energy systems. This review evaluates the utilization of bioenergy in cogeneration and trigeneration systems. The statistical reports of bioenergy and combined heat and power deployments in 28 countries of the European Union are discussed. Then, the most common research objectives of biomass-fueled combined heat and power systems are classified into three primary performance analyses, namely, energy and exergy analysis, thermo-economic optimization, and environment assessment. The influencing parameters of biomass utilization on each type of assessment are discussed, and the basic principles for carrying out such analyses in energy systems are explained. It is illustrated that the properties of feedstock, selection of appropriate conversion technology, associated costs with the biomass-to-bioenergy process, and sustainability of biomass are the primary influencing factors that could significantly affect the results of each assessment
