Abstract

Introduction: Iron  deficiency  anemia  is  the  most  common  type  of  anemia  in  the  world  and  the  most  important  disease  which  has  overlapping  diagnosis  with  it  is  &  thalassemia  minor.  For  diagnosis  of  theses  two  diseases, serum  ferritin  measurement  and  hemoglobin  laboratories  throughout  the  country  now, finding  some  tests  which  are  easier. More available  and  cheaper  for  different  of  these  two  mentioned  diseases, are  useful.  Therefore  in  this  article, reticulocyte  counting  test, after  a  short  period  of  iron  consumption, was  evaluated.
Material  and  Method: This  study  is  descriptive  and  cross-sectional. The  sample  population  consists  of  69  patient  with  hypochromic  microcytic  anemia  which  serum  ferritin  measurement, reticulocyte  counting  and  hemoglobin  electrophoresis  for  each  of  there  were  done.  After  7  days  treatment  with  oral  iron  tablet, reticulocyte  counting  test  for  each  of  them  was  done.  If  reticulocyte  counting  test  had  increased, the  patient  was  considered  as  iron  deficiency  anemia, on  the  other  hand, the  results  of  reticulocyte  count  test  was  compared  with  serum  ferritin  test  and  hemoglobin  electrophoresis  results  and  then, sensitivity  as  well  as  specificity  of  mentioned  test, were  analysised.
Results: Sensitivity  and  specificity  of  mentioned  test  for  iron  deficiency  anemia  were  82  and  67  percent  and  in  B  thalassemia  minor  were  64  and  78  percent, respectively. These  results  show  high  sensitivity  of  this  test  for  iron  deficiency  anemia  and  high  specificity  for  B  thalassemia  minor.
Conclusion:  It  seems  that, in  circumstance  which  serum  ferritin  measurement  and  hemoglobin  electrophoresis  aren’t  available, applying  reticulocyte  count  test  for  deferenciation  of  these  two  diseases, is  helpful.

Abstract

Introduction: Nearly, 6% of recently diagnosed cancer in the United States was upon to lymphoproliferate and leukemia and 9% of fatality in cancerous people was upon to these two illnesses. Using some simple, cheap and in-hand tests and special consideration to clinical inspections in suspected subjects provide a faster diagnostic and suitable treatment. It may ultimately promote the quality of life and decline the fatality among patients.
Materials and methods: This was a cross-sectional investigation which carried out during a 1.5 years in the form of forward direction. Forty-two lymphoproliferate (28 lymphoblast and 14 Hotchkin) and 21 acute lymphoblastic leukemia (10 acute lymphoblast leukemia and 11 miloid acute leukemia) subjects were evaluated. ESR, LDH and ALP levels were measured in all patients. In clinical examinations, oversizing of lymph nodes, spleen and liver were exactly considered.
Results: According to our results the best tests to rule in and rule out acute leukemia from lymphoprolifeatives were ESR and LDH, respectively. Additionally, The most sensitive and specific evaluations to rule out these two diseases were LDH and oversizing of liver inspection. It was also determined that LDH is the best screening test to rule out leukemia from lymphoproliferate.
Conclusion: Using of simple examinations such as ALP, LDH, ESR and more consideration to oversized spleen, liver and lymph nodes in each suspected patients, we could easily differentiate lymphoproliferate and acute leukemia from each other.

Abstract

Introduction: different  isotypes  of  antibody  can  be  produced  by  immune  system  after  antigen  contact.  Detection  and  measurement  of  different  classes  of  antibody  against  the  antigen  is  very  important  in  some  cases.  The  aim  of  this  study  is  designing  of  an  ELISA  method  on  the  basis  of  inhibition  of  enzyme  activity  by  using  a  non-competitive  inhibitor.  Therefore  in  this  study  rheumatoid  factor  is  used  as  a  model  for  the  detection  of  different  other  classes  of  antibodies  against  the  antigen.
Materials  and  Methods:  In  this  cross  sectional  analytical  study, we  measured  IgM  and IgA   rheumatoid  factors  in  sera  of  10  patients  with  rheumatoid  arthritis  and  positive  latex  test , by  mixed  and  routine  ELISA.  In  mixed  ELISA  the activity  of  the  first  conjugated  enzyme  was  blocked  by  a  non-competitive  inhibitor  after  adding  the  substrate. Then  the  next  conjugated  antibody, which  was  specific  for  another  isotype, was  added. By  optical  density, results  was  comparisoned  with  routine  ELISA.
Results:  The  obtained  results  showed  that  the  average  optical  density  is  lower  when  compared  with  routine  ELISA , but  the  difference  is   not  statistically  significant.  however  these  two  methods  did  not  show  any  significant  difference  in  quantifying  antibody  isotypes. Also  there  is  a  positive  association  between  mixed  and  routine  ELISA (r=0.9, p=0.001).
Discussion: Lower  optical  density  in  mixed  ELISA  is  probably  because  of  stick  hindrance  by  the  first  conjugate. So, because  there  is  no significant  difference  between  the  results  of  these two  types  of  ELISA, and  also  no  need  to  repeat  the  test  for  each  isotype  in  this  method, it  is  recommended  to  use the  new  method  instead  of  the  routine  one  to  save  time  and  reagents.

Abstract

Background: Major depression is one of the most prevalent psychiatric diseases, whereas schizophrenia is one of the worst human diseases. Therefore, finding low-cost treatment methods with few side effects can be of great help to patients. The present study was done to compare the serum levels of vitamin D, parathyroid hormone, calcium, and phosphorous in individuals with major depression and schizophrenics with healthy subjects. Materials and Methods: In this cross-sectional study, serum levels of vitamin D, parathyroid hormone, calcium, and phosphorous were assessed in 100 major depressive, 100 schizophrenic, and 100 healthy subjects. Subjects with a history of renal failure, hepatic failure, parathyroid disease, and consumption of vitamin D, parathyroid hormone, calcium, and phosphorous supplements were excluded from the study. SPSS software version 15 was used for data analysis. Results: Depression was accompanied with decreased serum levels of vitamin D and increased serum levels of parathyroid hormone (p>0.001, p=0.01), but there was not a significant difference between depression and healthy subjects in calcium and phosphorous serum levels (p=0.69, p=0.15). Schizophrenia presented a significant correlation with decreased serum levels of vitamin D and phosphorous (p>0.001, p=0.01), but there was not a significant difference between schizophrenic and healthy subjects in calcium and parathyroid hormone serum levels (p=0.47, p=0.67). Conclusion: Since depression and schizophrenia are accompanied by decreased serum level of vitamin D, consumption of supplementary vitamin D can be helpful in the treatment of these patients.

Abstract

Background: Immune thrombocytopenic purpurais an acquired disorder. Conventional treatment of immune thrombocytopenic purpuraincludes prednisolone (1mg/kg/day). Customarily, steroidsareadministered for about 3-6 weeks however,steroids have several side effects. The aim of this study was to compare theefficacy of two and three-week prednisolone therapy in patients with immune thrombocytopenic purpura Materials and Methods: In this randomized clinical trial, 66 patients with confirmed immune thrombocytopenic purpurawho had referred to KhansariHospital, Arak, were randomly selected and administered prednisolone (1mg/kg/day) for two and three weeks alternatively. Patients’ platelet count and complications associated with the treatment (diabetes and hypertension) were compared. Results: At the end of the treatment course, there was not a significant difference in mean platelet count between the two groups (p=0.748). Side effects in two and three-week protocols were 15.2% and 18.2%, respectively however, distribution of the complications (side effect) in the two groups was equal (p=0.9). Conclusion: Considering the absence of significant differencesin mean platelet count between the two groups at the end of the two treatment protocols and the higherpercentageof side effects in the patients that had received the three-week prednisolone therapy protocol, it seems that the two-week course of immune thrombocytopenic purpuratreatment is as effective as the three-week protocol.

Abstract

Background: Since nearly 90% of patients with acute promyelocytic leukemia (APL) have high telomerase activity and significant shortened telomere length, these patients have, therefore, been suggested to be good candidates for the therapeutic intervention with telomerase inhibitors. This study was done to investigate the effects of BIBR1532, a non-nucleoside inhibitor of telomerase, on APL cells. Materials and Methods: In this experimental study, for investigating the effect of BIBR1532, NB4 leukemic cells were cultured in the presence of various concentrations of BIBR1532. Succeeding apoptosis assay, Caspase-3 activity assay, and quantitative real-time PCR were applied to examine the effect of this drug on apoptosis percenage, enzymatic activity of Caspase-3, and quantitative expression of genes mRNA involved in apoptosis. Results: The results showed that BIBR1532 induced apoptosis in NB4 cells in a dose-dependent maner. Moreover, real time PCR results showed that BIBR1532 led to a significant decrease in mRNA of Bcl-2 gene and signficant increases in transcription of Bax, PUMA, and Caspase-3. Conclusion: Since treatment with BIBR1532 could exert rapid apoptotic cell death in NB4 cells andactivate cellular apoptosis route, anti-telomerase-based therapy can regarded as a suitable strategy for APL treatment. Patients with progressive shortening of telomere length and high levels of telomerase activity are suitable candidates for treatment with telomerase inhibitors.

Abstract
Background: Oxidative Stress and mitochondrial dysfunction leading to apoptotic death of neurons play key role in the pathogenesis of the Parkinson's disease. On the other hand، misregulation of microRNAs can cause several neurodegenerative diseases. Sirt1 and Bcl2 as two key genes, regulate pathogenic processes in neurodegenerative diseases such as mitochondrial dyfunction, oxidative stress and apoptosis.
 Materials and Methods: To investigate the role of microRNAs in model of Parkinson's disease, miRWalk 2.0 and TargetScan (v7) databases were served to predict microRNA-target interactions.
Results: Possible targeting effects of different microRNAs on Bcl2 and Sirt1 genes in Rat organism were analyzed. Merging data from databases has shown that rno-miR-449a, rno-miR-182, rno-miR-211, rno-miR-34b, rno-miR-34c, rno-miR-448, rno-miR-466b and rno-miR-96 with strong possibility can inhibit expression of Bcl2 gene. Also, rno-miR-181, rno-miR-211, rno-miR-27a, rno-miR-449a, rno-miR-34c, rno-miR-30, rno-miR-200a and rno-miR-448can inhibit Sirt1 gene with high possibility.
Conclusion: According to the findings, it can be predicted that regarding to high interaction scores of rno-miR-211, rno-miR-34c and rno-miR-448 and 449awith Bcl2 and Sirt1 genes in above-mentioned databases, these microRNAs probably can have critical role in disease process. Thus, these microRNAs can be introduced as appropriate candidates for investigations in in vitro model of Parkinson's disease.

Abstract

Background:
 
This study aimed to compare the effect of cold eye irrigation solution (BSS) and viscoelastic gel with their combination in room temperature on the dosage of sedative drugs which we use in Phacoemulsification cataract surgery.
 
Material and methods:
 
190 patients scheduled for cataract surgery under sedation were randomly divided into two equal groups. During surgery we used cold (4c) and warm (room temperature) BSS and viscoelastic gel in the first and second group respectively. For all patients we started sedation with Midazolam and Fentanyl and in case we needed additional drug we used Sodium Thiopental till we reached desired sedation level. Ramsay sedation scores (before, during and after surgery) and total sedative drug consumption   were evaluated   and compared between two groups and at the end of the surgery we checked the satisfaction score of patients and surgeon about the quality of sedation.
 
Results:
The average dosage of Midazolam wasn’t significantly different between the two groups, while the average dosage of Sodium Thiopental was significantly lower in Cold group. Also the average time of which we reached desired Ramsay sedation score and the level of Ramsay score were significantly different between the two groups.
 Conclusion:
Using cold BSS and viscoelastic gel in cataract surgery in comparison of their combination in room temperature will reduce the dosage of sedative drugs which we use during surgery and help us getting a more effective sedation and gaining both a satisfied patient and surgeon.

Abstract

Background and Aim: Human papillomavirus (HPV) infection is a prevalent, life-threatening disease and cause of cancer among women. Therefore, in recent years, developing novel anti-HPV agents is highly regarded. The study was planned to bioinformatic screening for E1 and E2 potential inhibitors of HPV serotypes including 16,18,31,33 and 45 types from medicinal plants.
Materials and Methods: This is a descriptive-analytic study. In the first step, three-dimension structure of phytochemicals were retrieved from PubChem database and then the cell cytotoxicity and mutagenesis potential of them were evaluated. In the next step, the amino acid sequences of two key proteins of mentioned types of HPV including E1 and E2 were obtained from Uniprot database. Furthermore, the conserved and variable regions of the protein sequences were predicted using multiple sequence alignment method. Finally, the three-dimension structure of mentioned proteins was determined by homology modeling method and potential interactions of the phytochemicals with the proteins were investigated using molecular docking method through Autodock 4.2.6 software.
Findings: The results demonstrated that ursolic acid has no cytotoxicity and mutagenesis potential with appropriate physicochemical properties. Results also showed that mentioned compound had strong interaction with both E1 and E2 of all studied serotypes. Furthermore, the evaluation of ursolic acid and E1 and E2 interactions showed that amino acid is involved in conserved regions of mentioned serotypes.
Conclusion: Based on the obtained results of present study ursolic acid could be good candidate for more in vitro and in vivo studies of its anti HPV activity.

Abstract

Background and Aim PBK is a mitogen-activated protein kinase (MAPKK) among MEK1/2 and MEK7 and can phosphorylate P38, JNK, and ERK in many cellular functions. The E2F transcription factor family also belongs to a class of cellular regulators acting as oncogenes and tumor suppressors. This study aims to investigate the expression of PBK and E2F7 in the early stages of colorectal cancer (CRC) compared to advanced stages based on the experimental and TCGA (The Cancer Genome Atlas) database.
Methods & Materials A total of 32 tissue samples of patients with CRC with the approval of a pathobiologist were collected according to the examination and criteria reported from different stages. After RNA extraction and cDNA synthesis, the RT-qPCR technique was used to evaluate the expression of the desired genes in the study groups. A receiver operating characteristic (ROC) curve analysis was also used to determine the ability of each of the selected genes to differentiate the two populations: stage I+II and stage III+IV.
Ethical Considerations In all stages of this research, codes of ethics of research and publication were observed.
Results In this study, it was shown that the expression of PBK and E2F7 significantly increased in stage I+II samples compared to stage III+IV. These data were confirmed by laboratory results and information extracted from the TCGA database. Also, based on the area under curve obtained from the ROC curves, these two genes are significantly distinguishable between stage I+II and III+IV populations in CRC.
Conclusion According to the results of this study, PBK and E2F7 genes are good markers in the diagnosis of CRC.
