Male NMRI mice weighing 20-25g were dividedinto five groups: negative control, positive control and three experimental groups, being injectedintraperitoneally by 250, 500 and 1000 mg/kg of hydroalcoholic extracts of Thymus carmanicus . The most effective dose of the extract was selected for the possible involvement of opioidergic systems. Animalsubjects were studied by pretreatment of opioid antagonist, naloxone. The data were analyzed throughANOVA and Tukey's test.Results indicated that in the formalin test,  thedoses of 500 and 1000 mg/kg of theextract significantly reduced the score of analgesic in experimental groups(P<0.001).Meanwhile, pretreatment with naloxone inhibited some of the extract induced antinociceptive effects in comparison to controlgroup.In writhing and hot tail immersion tests,all doses of theextract significantly alleviatedpain in experimental groups(P<0.01).  Moreover, the xylene-induced ear edema (P<0.001)as well asfoot edema in mercury immersion method was considerably reduced(P<0. 05). This study not onlyshowedthathydroalcoholic extract of areal parts of Thymus c armanicus hasanalgesic and anti-inflammatory effects but also indicated that some of the antinociceptive properties of Thymus carmanicus are mediated by opioidergic mechanism, which in turn validated the traditional uses of the plant in the treatment of pain.","PeriodicalId":16663,"journal":{"name":"Journal of paramedical sciences","volume":"46 1","pages":"36-44"},"PeriodicalIF":0.0,"publicationDate":"2018-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83411808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prognostic biomarkers could be valuable for predicting the relapsed ALL patients and may therefore contribute to improving ALL outcome. Presently, there are little data on the role of prognostic biomarkers in the risk stratification of ALL. The aim of the present systematic review is to survey the identified prognostic biomarkers of chALL. In this study, protein-protein interaction of identified biomarkers was evaluated to reveal the biological pathways related to high risk chALL. To pursue this goal, firstly all relevant studies were collected through the PubMed and Google Scholar databases with no restrictions. Then, the biomarkers of high risk patients were recorded and finally protein-protein interaction of biomarkers was analyzed through using the STRING database. After screening 82 abstracts, three studies were included with 36 high risk and 33 low risk B-ALL participants. Totally, 142 biomarkers were investigated in this study. Protein interaction network analysis of biomarkers revealed two main pathways, namely ribosome and spliceosome. Dysregulation of two key pathways, ribosome and spliceosome can be associated with the high risk phenotype of childhood acute lymphoblastic leukemia.","PeriodicalId":16663,"journal":{"name":"Journal of paramedical sciences","volume":"69 1","pages":"50-55"},"PeriodicalIF":0.0,"publicationDate":"2018-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88209536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present experimental study, the effects of dopamine, kisspeptin and the GPR54 receptor signaling pathway role in the mediating the dopamine effects  was determined on ghrelin secretion. Forty Wistar male rats weighing 220-250g in 8 groups received saline, 1nmol kisspeptin, 5, 15 or 45 microgram dopamine hydrochloride, simultaneous injections of 1nmol peptide 234 and kisspeptin, 15microgram dopamine and kisspeptin or peptide234 and 15microgram dopamine via third cerebral ventricle respectively. Blood samples were collected via tail vein. Mean serum ghrelin concentrations were determined by rat ghrelin kit and ELISA method. Kisspeptin significantly decreased mean serum concentration compared to saline group, while 15 or 45 microgram dopamine significantly increased mean serum ghrelin level compared to saline group. Kisspeptin significantly blocked the stimulatory effects of dopamine on ghrelin secretion compared to dopamine group. Dopaminergic and kisspeptin/GPR54 signaling pathways may interact to control the ghrelin secretion at hypothalamic level. Stimulatory effects of dopamine on ghrelin secretions could exert partly via decreasing the activity of hypothalamic kisspeptin neurons.","PeriodicalId":16663,"journal":{"name":"Journal of paramedical sciences","volume":"7 1","pages":"29-35"},"PeriodicalIF":0.0,"publicationDate":"2018-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81673706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Localization, classification, prediction and connectivity are the most common issues. Functional connectivity is a branch of fMRI that focuses on connectivity between voxels and ROIs. There are several methods for investigating functional connectivity such as correlation analysis. In any field, it is very important that results of any research have reliability according to the experiment. Any methods and measurement instruments need to be reliable. Without reliability, results are meaningless and our research is not trustworthy. Brain imaging can be used as a valuable tool for pre-surgical planning, so the results should be highly reproducible. Test-retest reliability can be explored using the intra-class correlation coefficient (ICC). I2C2 is an extent of ICC to verify the reliability in high-dimensional data as imaging studies. 13 subjects of test-retest resting-state fMRI are used to investigate reliability. I2C2 of four ROIs are also computed (Caudate, Cingulate, Cuneus and Precentral regions). Functional connectivity is found to have moderate reliability ranging 0.6244 to 0.6941. 95% confidence interval of I2C2 is calculated by nonparametric bootstrap in which CI of Caudate region I2C2 has the shortest length.","PeriodicalId":16663,"journal":{"name":"Journal of paramedical sciences","volume":"16 1","pages":"16-20"},"PeriodicalIF":0.0,"publicationDate":"2018-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73023383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inappropriate follow up after discharge will increase the risk of re-admission and re-hospitalization which leads to the poor performance of the health system. The aim of this study was to determine the effect of physician's caring after discharge on re-admission and referral to doctors.This study was conducted as a clinical trial on patients with early intervention for educational instruction. The clinical trial was conducted at a later stage on 120 patients with heart failure who were hospitalized in Taleghani Hospital, Tehran. For a period of five months after discharge, using block randomization, the subjects were divided into two groups, including intervention and control groups. At the time of discharge, the patients in the intervention group received instructions and were trained by physicians, while no intervention was applied for the subjects in the control group . In addition to demographic questions, the patients were asked about two main outcomes, i.e. \"re-admission\" and \"referral to doctors\".  To collect the required data, the subjects in both groups were contacted via telephone calls (nine times) every week in the first month after discharge and two times per week in the following two months. Generalized linear mixed effects model method was used for evaluating the effect of physicians caring after discharge on re-admission and re-hospitalization.The results of this study showed that with the passage of time (weekly) after discharge, there was a significant increase in the rate of re-admission in the control group, while there was no significant increase in re-hospitalization. There was no statistical evidence showing a significant difference between the rates of re-admission along with the time in the treatment intervals. In other words, the patients in the control group experienced a significant increase in the odds ratio of re-admission over the time.","PeriodicalId":16663,"journal":{"name":"Journal of paramedical sciences","volume":"17 1","pages":"7-15"},"PeriodicalIF":0.0,"publicationDate":"2018-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73895767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Essentially, one of the important ways for bacteria such as P. aeruginosa  to survive in the presence of antibiotics is biofilm formation. In the current report, we have focused on inhibiting the microbial biofilm formation of P. aeruginosa  through combining glutathione (GSH) coated silver nanoparticles (AgNPs) and Ciprofloxacin (Cip). Materials and Methods: AgNPs were biosynthesized using Eucalyptus Camaldulensis leaf extracts and surface modification of AgNPs was done, using glutathione.  Synthesized nanoparticles were characterized by FTIR, XRD, DLS, SEM, and CHN tests. Then, 50 isolates of P. aeruginosa were originated from different samples of hospitalized patients from Sina hospital and 24 isolates were selected as a strong biofilm producer using microtiter plate method for further studies. Finally, the synergistic effect of GSH-coated AgNPs and Cip was investigated on biofilm formation of P. aeruginosa . Result: The images of SEM represent the spherical structure of silver nanoparticles with a smooth surface. Also, the results of FTIR, XRD, DLS, SEM, and CHN of AgNPs before and after surface coating confirmed the formation of GSH-coated AgNPs. GSH-coated AgNPs and Cip at a concentration of 1/2 and 1/4 MIC had an inhibitory activity on biofilm formation of 87.5% and 83.4% of P. aeruginosa isolates respectively.
