- چکیده:
- چکیده انگلیسی: Three-dimensional reconstruction of objects is one of the key elements in production processes. Stereo vision is one of the robost techniques in this field. Accuracy of the reconstruction is influenced by several parameters that mainly determined through the calibration process. Besides, symetring of two accquired images effects on the accuracy. In the present research, a three-dimensional model reconstruction system based on stereo vision technique included a camera, a robot, a lightening system, a cubic object, and IMAQ Image Processing and LabVIEW Softwares. The inactive stereo vision was considered such that the images were acquired by the same camera in two different positions. The cuboid model was implemented after camera calibration. The corners of the object were considered to remove the symmetry problems. After comparing the dimensions of the reconstructed model with those of real objects, the maximum error value of the system was obtained as 0.75 mm and the error variance as 0.09 mm.

- چکیده:
- چکیده انگلیسی: Sarabi cattle are found in Iran and Azerbaijan. They are used for both dairy and meat production. A histological study was carried out on the teat of Sarabi cattle for the first time in Iran. A total number of five adult and healthy cows were selected and after slaughtering, tissue samples were taken from different parts of the teat skin. After fixation in 10% formalin, they were transferred into the tissue processor. Paraffin blocks were made and thin sections of 6µ, were cut. The sections were subjected to stain by Hematoxylin and Eosin. They were studied under the light microscope and photo micrographs were taken. The results show that the teat consists of teat sinus, teat wall, teat canal and teat orifice. Teat wall includes three separable strata: skin, middle layer and mucosal layer.Teat skin contains an epidermis and dermis, but there is no evidence of hypodermis existence in contrast with the other parts of the body. Dermis is formed from networks of collagen fibers, blood vessels, circular smooth muscle and nerve fibers. Meissner’s corpuscles are found in the dermal papillae particularly in the connective tissue of teat canal. Myelinated nerve fibers are also seen in this region.

- چکیده:
- چکیده انگلیسی: Rutilus frisii kutum is a cyprinid fish, distributing along the Caspian Sea, from Atrak River (Turkmenistan) to Kura River (Azerbaijan). This fish is one of the commercially important fishes in the south of the Caspian Sea. This species is normally a medium-sized fish, typically reaching 45-70 cm in length, weighing up to 5 kg. The kidney of the vertebrate is the main organ which balances the body fluid homeostasis. A histological study was carried out on the nephron of Rutilus frisii kutum for the first time. A total number of ten adult fish from the southern Caspian Sea fishing region were subjected to this investigation. The kidneys were removed and immediately fixed in 10% buffered formalin for 24 hours. Then, they were transferred into the tissue processor. Paraffin blocks were made and thin sections of five microns were cut. The sections were subjected to staining by Haematoxylin & Eosin. They were studied under the light microscope and photomicrographs were taken. The different parts of nephron were renal corpuscles, two types of proximal convoluted tubules, an intermediate segment and collecting ducts. There were no evidence for distal convoluted tubules and henle loops.

- چکیده:
- چکیده انگلیسی: Urinary tract infections are one of the most common infectious diseases that lead to significant health problems in the world. Urinary tract infections are referred to any infection in any part of the renal system. Uropathogenic Escherichia coli, Proteus mirabilis, and Klebsiella are main organisms that are involved in these infections.
After identifying same protective and conserved virulence sequences in these microorganisms with similarity upper than 80%, sequences of synthetic gene was provided by bioinformatics techniques and ordered from Thermo Fisher Scientific Company. PCR amplification of this gene was performed by specific primers designed for this purpose. Construction of gene was performed by overlap PCR. The synthetic gene was cloned into pET28a vector. Our gene was amplified in E. coli Top10 tested.
To confirm cloning, three methods including colony PCR, digestion and sequencing were used. First, two techniques were performed using horizontal electrophoresis, and also the synthetic gene showed significant homology with the sequence (99% Identified) in sequencing. Sequencing of this gene showed that fusion was constructed correctly. Determination of biochemical properties such as 3D structure, Ramachandran and comparison of Non-redundant Set of PDB structure was done by bioinformatic software and had exact and expectable results.
A large part of the health system in the world is occupied by a urinary tract infection and governments spend a huge amount of money for the treatment and recovery of patients with these infections. On the other hands, antibiotic resistance in the not-far future will be a disaster for medical societies. This is the most important reason for the emergence of vaccine production against urinary tract infections.- انتشار مقاله: 30-05-1396

- چکیده:
- چکیده انگلیسی: Background: The aim of this study was to assess the relationship between hypertension and aldosterone-renin ratio (ARR) with the severity of coronary artery disease (CAD). Methods: This cross-sectional study was performed on non-diabetic patients who were candidate for coronary angiography in Shafa hospital in Kerman in 2017. The levels of active renin and aldosterone were measured by the radioimmunoassay (RIA) method before angiography. All patients underwent coronary angiography to determine the severity of CAD. The CAD severity was described by the Gensini score. Results: Of the 306 patients, 174 (55.1%) were hypertensive. The overall prevalence of CAD in hypertensive and normotensive groups was not statistically different (39.7% versus 38.9%, p = 0.898). In groups with and without hypertension, normal coronary arteries were found in 60.3% and 60.8%, single-vessel disease in 15.5% and 17.7%, two-vessel disease in 14.4% and 11.5%, and three-vessel disease in 9.8% and 10.0%, respectively. The differences were not significant (p = 0.880). The average Gensini scores in hypertensive and normotensive groups were 29.27 ± 28.42 and 33.74 ± 33.05, respectively with no significant differences (p = 0.370). The mean ARR in those with normal coronaries, one, two, and three-vessel diseases was 3.17 ± 7.63, 2.51 ± 4.21, 1.93 ±1.57, and 1.20 ± 0.68, respectively with no significant difference (p = 0.696). We did not observe any association between the Gensini score and ARR (r = -0.126, p = 0.263). In multivariable linear regression model (Table 3), ARR could not predict the severity of CAD assessed by determining the Gensini score (Beta = -0.463, p = 0.636). Conclusion: There was no significant relation between hypertension and ARR to the severity of CAD.

- چکیده انگلیسی: Background: Diabetes is a global health problem that its prevalence is increasing rapidly. Rosa damascena extract has shown to have an intensive non-competitive inhibitory effect on α-glucosidase in an animal study. The aim of this study was to assess the safety and efficacy of Rosa damascena (RD) Mill in diabetic patients and healthy subjects. Methods: In a triple-blind, placebo and Acarbose-controlled randomized trial in Kerman in the south-east of Iran, we randomly allocated diabetic patients (n=32) and healthy volunteers (n=28) to 100mg Acarbose, 200 mg RD-methanolic extract, 400mg RD-methanolic extract and placebo groups. Over 15 days, the participants were followed up to monitor the changes in blood biochemical parameters and apparent symptoms. Analyses were carried out by intention to treat. Results:RD extract decreased postprandial blood glucose levels comparable to the effects of Acarbose, demonstrating its α-glucosidase inhibitory activity. Besides, fasting plasma glucose levels significantly decreased in patients treated with 400 mg/day RD-methanolic extract compared to the 200 mg RD-methanolic extract (127.6±26.8vs. 165.5±27.1, p=0.041), suggesting that Rosa damascena Mill is effective in a dose dependent manner. No major or minor hypoglycemic event was observed. NO adverse event was observed in the RD treatment groups in comparison with Acarbose or placebo groups. Serum levels of biochemical parameters did not fluctuate significantly in RD treatment groups compared to Acarbose and placebo controls. Conclusion:Rosa damascena not only decreases blood glucose levels, but also is safe to be used for the purpose of controlling blood glucose levels in drug naïve patients with type II diabetes.

- چکیده:
- چکیده انگلیسی: Background: A majority of people widely use acetaminophen as a sedative. Overusing the drug for prolonged periods of time can lead to acute liver damage. Mumijo, as a strong antioxidant and anti-inflammatory drug, could possibly reduce some of the acetaminophen-induced side effects on the liver. Thus, the aim of this study is to evaluate the effect of Mumijo on the liver damage caused by the use of acetaminophen. Methods: 40 male Wistar rats were randomly divided into five groups: sham, acetaminophen, low and high doses of mumijo, and vehicle. All groups except the sham group received a single dose of 500 mg/kg acetaminophen via ip injection. Then the groups that were under treatment received 150 mg/kg (low dose) and 250 mg/kg (high dose) of mumijo, and the vehicle group received distilled water as vehicle. After 24 hours, blood samples were taken for biochemical tests, and a part of the liver was extracted for histopathological examination. Results: acetaminophen increases the activities of functional liver enzymes including alanine amino transferase (ALT), aspartate aminotransferase (AST), and gamma glutamine transferase (GGT). In groups under treatment, values of the mentioned enzymes were significantly reduced in comparison with the acetaminophen and vehicle groups (P <0.05), and on the other hand, malondialdehyde (MDA), nitric oxide (NO), and protein carbonyl (PC) increase caused by acetaminophen were reduced by mumijo. Furthermore, the amount of glutathione (GPX) was increased by mumijo (P <0.05). From a histopathological point of view, necrosis and liver damage caused by acetaminophen was decreased by mumijo. Conclusion:The findings showed that mumijo is salient in preventing liver damage caused by consumption of high doses of acetaminophen probably through reducing oxidant activities and also through increasing anti-inflammatory and antioxidant activities.

- چکیده:
- چکیده انگلیسی: Background & aim: Despite the advantages of natural childbirth and complications associated with cesarean section, rate of cesarean delivery has increased dramatically in recent years. Therefore, appropriate training is essential to reducing this trend. This study aimed to evaluate the effects of training about the benefits of natural childbirth on the attitude and intention to select the mode of delivery in nulliparous women.
Methods: This randomized clinical trial was conducted on 64 nulliparous women with normal pregnancy at 30-34 weeks of gestation without indication for cesarean section referring to the health centers of Mashhad, Iran in 2014. Participants were randomly divided into two groups of intervention (training) and control. Training was focused on the benefits of natural delivery and performed in four sessions (60 minutes) using videos and slides. In both groups, pre-test and post-test were carried out using valid and reliable questionnaires. Data analysis was performed in SPSS V.22 using Fisher's exact test, Chi-square, Wilcoxon test, T-test, and Mann-Whitney U test.
Results: Mean score of attitude toward natural delivery had a significant difference in the intervention group before and after training (P<0.001). Mean difference in the score of attitude toward cesarean section was significantly higher in the intervention group compared to control group (P<0.001). Moreover, frequency of intentions to select the mode of delivery was significantly different in the intervention group before and after training (P=0.004).
Conclusion: According to the results of this study, training on the benefits of natural childbirth could positively influence the attitude of pregnant women toward natural delivery and reduce the rate of elective cesarean section.- انتشار مقاله: 15-04-1395
