Methods: Paraffin blocks of colonic
adenocarcinoma tissue from 30 patients were
collected from the Pathology Department of Khatam Al Anbia Hospital in Zahedan, Iran.
Sections, 5-7μm thick, were prepared and stained
using hematoxylin and eosin. Sections were graded histopathologically and then stained
using the lectin Ulex europaeus agglutinin (UEA, 10μm/mL), which binds specifically to
L-fucose, and Alcian blue (pH=2.5). Sections were graded blindly according to lectin
staining intensity on a scale of 0-3. Collected data were analyzed using Kruskall-Wallis
and Mann Whitney nonparametric tests with SPSS.
Results: Our results show that there is a
significant difference in the staining intensity for L-fucose between tumoral
cells of different grades of colon carcinoma (p<0.001). Results show that the degree of UEA lectin binding to cancer cells is lower in the
cytoplasm and nucleus and higher in the extracellular matrix in tumors, with the
degree increasing with histopathological grade. Furthermore, staining intensity
differs in different portions of cancer cells.
Conclusions: The increased staining intensity of L-fucose in the
extracellular matrix of colon carcinoma is a reflection of the aberrant protein
glycosylation pathway in neoplasia.

Background: With respect to the importance of hepatitis B
vaccination of high-risk groups such as prisoners, this study was performed to assess
the comparability of a short-course double-dose vaccination schedule with the
standard 3-dose schedule.
Methods : Within a randomized clinical trial, a short-course vaccination (at months 0
and 1) with 20
microgram (double-dose) doses of the vaccine was compared to the standard
method of hepatitis B vaccination (at
months 0, 1 and 6,
with 10-microgram doses) in 100
prisoners in Zahedan city in Iran in 2009.
We made sure the sera from all the individuals were negative for markers of
previous hepatitis B infection. Subsequently
serum from all the participants was tested for anti-HBs
antibody 1, 2 and 7
months after the first dose of vaccination.
Results : Seroconversion rates (HBsAb>10
mIU/ml) 1, 2
and 7 months after the first dose of vaccination
were similar in the routine (11%, 79% and 94%,
respectively) relative to the double-dose group (26%, 95% and
93 %, respectively). The mean values of anti-HBs
antibody titers were similar in the 1st and 2nd
months for the two groups but it was significantly higher (P=0.002)
in the routine dose (514 mIU/ml)
versus the double-dose group (130 mIU/mL),
in the 7th month.
Conclusion: Demonstrating
comparable results with the standard 3-dose
schedule, it seems that short-term double-dose vaccination for hepatitis B is
a safe and acceptable method for use in high-risk groups such as prisoners.

Background: Maternal mortality is one of the most important indicators of women health standard in developing countries. This study aimed to determine the prevalence of risk factors and etiology of maternal mortality in a geographic region of Iran. Methods: This descriptive- analytic cross sectional study included all pregnant women who died during pregnancy and six weeks after delivery due to pregnancy related fac-tor. The study was done in Sistan region in the north of Sistan and Baluchestan Prov-ince of Iran from April 2002 to March 2014. The immigrant women were excluded. Data were collected using 3 parts questionnaire. The validity and reliability of ques-tioner were approved by experts in this field. Data were analyzed using the statistical software SPSS version 18, Chi-square test and ANOVA analysis were performed. Results: The total number of deliveries during this time period was 60496. The total number of maternal mortality was 57 patients which means 94.2 out of 100.000 live births. Most of the dead mothers had more than 35 years old (46.9%), gestational age was more than 22 weeks (77.2%), gravidity more than 4 (21.1%), pregnancy interval lower than two years (46.9%) and 75.4% of death was in post-partum. The main cause of mortality was post-partum hemorrhage (19.3%). Conclusion: Based on our findings, some factors including multiparity, pregnancy his-tory more than 4 times, short interval between pregnancies lower than 2 years and ma-ternal age more than 35 years were some risk factors for maternal death. Maternal mortality in the postpartum period was more than pre-delivery period. Bleeding was the main cause of maternal mortality. Therefore monitoring of vital signs in the post-partum period and the proper management of bleeding are very important. It is sug-gested that risk assessment should be done for pregnant women in delivery ward for detecting high risk pregnant women. Suitable management for these women especially for patients with postpartum hemorrhage plays an important role to decrease the ma-ternal mortality.

Methods: In this cross-sectional study, 200 pseudomonas aeruginosa isolations (from 86 males and 114 females) were collected from different samples such as urine, blood, wound, catheter and other samples from teaching hospitals in Zahedan City during nine-month period in 2017. After conducting biochemical tests and confirming bacterium type, based on Clinical Laboratory Standards Institute (CLSI), the antibiotic resistance of strains for 10 antibiotics was determined using disk diffusion method. In addition, the minimum inhibitory concentration of three antibiotics such as imipenem, piperacillin/tazobactam and ceftazidime were determined through E-test. The Chi-square test was used for statistical analysis through the SPSS software, version 16 (IBM SPSS, Armonk, NY, USA).
Results: Out of 200 pseudomonas aeruginosa isolations (from 86 males and 114 females), the maximum resistance was related to ciprofloxacin (37%) and gentamicin (28.5%). The minimum resistance was related to piperacillin/tazobactam (6.5%) and ceftazidime (6%). The highest separated strain was from urine sample (54%), blood sample (23.5%) and wound sample (10.5%). Additionally all strains were sensitive to colistin. In this study, the percentage of multidrug-resistance (MDR) and extensively drug-resistant (XDR) strains were investigated, which were 13% and 5.5%, respectively.
Conclusion: In this study, pseudomonas aeruginosa isolates had the lowest resistance to ceftazidime which this antibiotic could be the main treatment option. The high prevalence of MDR strains is a serious warning.

Methods: This study compared the experimental and control groups of pregnant women who were referred to Zabol health centers and it was performed from May 2017 to November 2017. The statistical population included 70 pregnant women of which 35 cases were selected as the experimental group and 35 cases as the control group. For the experimental group, 8 sessions of counseling and training for natural childbirth were held. Data in two stages were collected. Up until the end of pregnancy, both groups were followed and the method of delivery was evaluated. Data was analyzed by using descriptive statistics and Chi-square test in SPSS software, version 23 (SPSS Inc., Chicago, IL, USA).
|
Results: Based on the obtained data, it was observed that out of the participants in the training classes, 5 cases (14.3%) had cesarean section and and 30 cases (85.7%) had a normal delivery. 18 cases (51.4%) of the control group had the natural method and 17 cases (48.6%) were delivered by cesarean section. It was observed that there was a significant difference between the control and intervention groups in the type of delivery method, therefore, 85.7% of the intervention groups had a normal delivery (P=0.002).
Conclusion: The results of this study showed that participation in childbirth preparation classes were influenced for the choice of delivery. |

Methods: The present study is a clinical trial without a control group. 119 women referred to Shahid Beheshti and Al-Zahra hospitals in Isfahan, aged 28-49 years, with rectocele and cystocele, uterine prolapse and a candidate for perineal surgery and anterior-posterior vaginal repair, entered the study from October 2020 to August 2021. Data collection tools were three questionnaires on Female Sexual Function Index (FSFI), Multidimensional Body–Self Relations Questionnaire (MBSRQ), and Short-Form Health Survey (SF-36) that were completed before and 6 months after surgery by interviewing individuals. All surgeries were performed by a Fellowship in pelvic floor disorder, and the type of surgery was the same in all patients. Data were analyzed using a dependent t-test.
Results: Data of 119 women with rectocele, second and third-degree cystocele with maximal grade 1 apex prolapse, and candidates for perineorrhaphy and anterior-posterior vaginal repair were evaluated. The mean age of the study samples was 36.40±6.39 years and the age range was 28 to 49 years (before menopause).
In the postoperative stage; perineorrhaphy and anterior-posterior vaginal repair affect body image, improvement of sexual function, and quality of life in women (P<0.001).
Conclusion: It seems that perineorrhaphy and anterior-posterior vaginal repair affect the body image, Improving sexual function and quality of life, and can be effective in improving the quality and improving the relationship between couples who need this surgery.

Methods: The present study was carried out from April 2019 to August 2019 in Mashhad University of Medical Sciences. In this study, two decellularization protocols were compared using sections of human kidney tissue. Therefore, two human kidneys which collected from Ghaem and Imam Reza hospitals were used. In the first protocol, detergents such as 1% Triton X-100 (1A) and 1% SDS (Sodium Dodecyl Sulfate) (1B) were employed, followed by the application of DNase I. The second protocol utilized 0.5% SDS (2A) and 1% SDS (2B). The effectiveness of these techniques was evaluated using hematoxylin and eosin (H&E) staining, 4',6-diamidino-2-phenylindole (DAPI), DNA quantification, and immunohistochemistry (IHC).
|
Results: Based on H&E staining results, comparison of the decellularized and native human kidney tissues showed a successful elimination of cell nuclei and the ameliorate extracellular matrix preservation in triton-treated scaffolds (1A) in comparison with the SDS-treated scaffolds (1B) at all times protocols. Furthermore, DNA quantification illustrated triton X-100 in removing DNA was more effective in eliminating DNA from kidney tissues compared to other protocols in renal tissues. In addition, IHC staining demonstrated that the expression of collagen IV and laminin was preserved throughout the decellularization process with Triton X-100 on day fifth. Also, IHC staining indicated human leukocyte antigen (HLA) was completely eliminated in the cortex-medulla of human scaffolds treated with Triton X-100 within day fifth.
Conclusion: Our results demonstrated that triton X-100 outperformed SDS as a detergent for decellularizing human kidneys. Meanwhile these results indicate suitable method for decellularization of human kidneys to produce functional kidneys. |

Background: Nonalcoholic fatty liver disease (NAFLD) is one of the most prevalent chronic liver diseases worldwide and is closely associated with metabolic syndrome and insulin resistance. Growing evidence suggests a link between NAFLD and cardiovascular diseases, independent of traditional risk factors. Coronary computed tomography angiography (CCTA) is a reliable noninvasive method for evaluating coronary artery disease (CAD) and identifying high-risk coronary plaque characteristics. However, data regarding the association between NAFLD and high-risk coronary plaques remain limited, particularly in Iran. This study aimed to evaluate the prevalence of NAFLD in patients with high-risk coronary plaques detected by CCTA. Methods: In this cross-sectional study, 200 patients who underwent CCTA for the evaluation of coronary plaques in outpatient clinics or the emergency department of Golestan Hospital in ahvaz ,1403 ,were enrolled. Demographic data, including age, sex, weight, and body mass index (BMI), along with clinical characteristics and cardiovascular risk factors such as hypertension, diabetes mellitus, dyslipidemia, smoking status, and medical history were collected. Patients with a history of alcohol consumption or known liver disease were excluded. NAFLD was assessed based on imaging findings. Statistical analyses were performed to compare variables between patients with and without NAFLD. Results: The mean age of patients with NAFLD was 57.89 ± 9.72 years, compared with 55.77 ± 8.97 years in patients without NAFLD, with no statistically significant difference. The prevalence of NAFLD was slightly higher in women than men; however, this difference was not significant. Patients with NAFLD had a significantly higher mean weight than those without NAFLD (85.21 ± 12.12 kg vs. 79.62 ± 11.85 kg; p = 0.001). Additionally, the prevalence of NAFLD increased significantly with higher BMI categories, particularly in obese individuals. Conclusion: Age and gender were not significantly associated with NAFLD prevalence in patients with high-risk coronary plaques. In contrast, increased body weight and higher BMI, especially obesity, were independently associated with a higher risk of NAFLD in this population. |
