Abstract
ABSTRACT
Background and Objectives: The incidence rate of esophageal cancer (EC) is high in north and northeast of Iran. Taurine is a sulfur-containing amino acid with a wide range of vital biological functions. The aim of this study was to compare plasma levels of taurine between patients with EC and healthy controls.
Methods: Plasma samples from 36 recently diagnosed cases of EC and 36 healthy adults were analyzed by high-pressure liquid chromatography. Data analysis was done using SPSS (version 16). The t-test was used to evaluate significant differences in the level of taurine between the two groups. P-values less than 0.05 were considered statistically significant.
Results: Patients with EC had significantly higher levels of plasma taurine compared with the controls (P<0.05).
Conclusion: Patients with EC have significantly higher levels of plasma taurine compared with healthy individuals. This finding suggests that the measurement of plasma taurine in patients with EC could be useful for the early diagnosis of the disease.
Keywords: Esophageal Cancer, Taurine, HPLC.

Abstract
Background and objectives: Intraoperative blood transfusion is a common medical intervention worldwide. Although mostly lifesaving when indicated, inappropriate administration of intraoperative can be potentially life-threatening. The aim of this study was to analyze the most common surgery/invasive procedures requiring intraoperative transfusion and to determine indications for intraoperative transfusion as well as the outcome of the patients after intraoperative transfusion.
Methods: A retrospective review of the electronic database of medical records was done for surgical patients who received intraoperative transfusion from June 2019 to December 2019. Preoperative hemoglobin values, associated comorbidities, and physiological triggers including hypotension and tachycardia were recorded. Descriptive statistics were used to summarize the data.
Results: A total of 36 patients (age range: 9-80 years) were studied. Orthopedic surgeries (53%) were the most common surgeries that required intraoperative transfusion. Preoperative anemia (hemoglobin <10 g/dl) was the predominant reason for intraoperative transfusion. Type 2 diabetes mellitus (36.3%) was the most frequent comorbidity among the cases of intraoperative transfusion. Half the cases received two units of packed red blood cell (pRBC), while 39% of the cases received one unit of pRBC. The remaining 11.1% received more than two units of pRBC. Furthermore, 77.7% of the patients were discharged to home within a week, while 16.6% of the patients were discharged after a prolonged hospital stay (> one week). The remaining 5.5% died in the hospital within a week of the procedure/surgery.
Conclusion: Transfusion practices vary among physicians, hospitals, and countries. The findings highlight that the hospital might be the most important determinant of the number of administered transfusions, with some adopting programs to reduce transfusions for elective surgery.

Abstract
Background: Cardiovascular diseases, especially coronary artery problems, are the main causes of death. The aim of this study was to evaluate the expression of NOs and NOX2 in coronary artery patients after aerobic exercise and omega-3 intake.
Methods: The present study was a quasi-experimental study in which 32 men with coronary artery disease in the age range of 55 to 65 years were selected and randomly divided into 4 groups: control, exercise, omega-3, and omega-3 + exercise. The training program consisted of 8 weeks of intermittent running training, 3 sessions per week, with an intensity of 55 to 65% of the subjects' heart rate reserve and with an emphasis on gradual overload. Subjects consumed 1000 mg of omega-3 daily.
Results: There was a significant increase (P <0.0001) in the mean expression of the NOS gene in the exercise + omega-3 group compared to the control group. The mean ratio of NOX gene expression changes in the exercise group, omega-3, and the combination of exercise + omega-3 was significantly reduced compared to the control group (P <0.0001).
Conclusion: According to the results of the present study, the ability of exercise and omega-3 supplementation to reduce the level of oxidant stress and increase homeostasis control in coronary artery insufficiency shows an important molecular mechanism that underlies the benefits of these interventions.

Abstract
Background: Vulvovaginal candidiasis (VVC) remains one of the most common infections of the female genital tract. This local study was conducted to identify the spectrum of Candida species associated with VVC and recurrent vulvovaginal candidiasis (RVVC) using different phenotypic and genotypic methods and assess their fluconazole susceptibility.
Methods: High vaginal swabs were collected from 576 patients with VVC. Swabs were subjected to KOH 10% and cultured on Sabouraud dextrose agar. The species identification of Candida isolates was made using phenotypic methods, including the germ tube test, corn meal agar (CMA), CHROMagar Candida, and PCR-RFLP as the best genotypic methods for confirmation of Candida species in vulvovaginal candidiasis. Fluconazole susceptibility testing was performed using the disk diffusion method.
Results: The data were analyzed using the chi-square test. The prevalence of candidiasis was 61%. The socio-demographic profile corresponded to a woman aged 29.14 ± 4.8 years on average, pregnant (77%), diabetic (19%), with hypertension (10%), recurrent (9%), a history of fluconazole use (4%), and under 30 years of age (73%).
Vaginal swab cultures yielded Candida growth in 352 cases (61%). Candida albicans was the predominant isolated species (78%), while the most common non-albicans species were C. glabrata (14.7%), C. parapsilosis (4.2%), C. tropicalis (2.8%), and C. krusei (0.56%). Isolates of C. glabrata and C. krusei exhibited the highest rate of DDS resistance among all isolates tested.
Conclusion: C. albicans was the most common species. Careful periodical surveillance is needed to identify any changes in the susceptibility patterns to fluconazole with the increased use of this antifungal agent in Sayad Shirazi tertiary care hospital, Iran.

Abstract
Background: Human papillomaviruses (HPVs) are DNA viruses from the Papillomaviridae family. These viruses are linked to about 5% of human cancers, with a significant association with cervical cancer. Infection with this virus can be screened in women to prevent cervical cancer.
Methods: This review analyzes articles published over the last two decades regarding self-sampling, papillomavirus, and cervical cancer. The search for articles was conducted using various scientific databases, with selections based on their relevance to the topic and their contribution to understanding and comparing methods. Key results were examined, focusing on social aspects, economic savings, and participants' satisfaction with the self-sampling method.
Results: One of the most common and effective methods for HPV screening is sampling from the cervix using the Pap smear method and molecular techniques, widely used in various countries. Currently, HPV screening methods in different countries are primarily limited to clinical sampling, which cannot cover all urban and rural populations. The World Health Organization has recommended and supported self-sampling for HPV screening as a new strategy.
Conclusion: This mini-review discusses the self-sampling method for HPV screening, its advantages, and its application in different countries. As self-sampling can address the needs of both rural and urban areas, it is more economically viable and helps minimize cultural barriers and public opinion challenges compared to clinical sampling. The HPV self-sampling strategy offers an effective and efficient method for HPV screening, aiming to cervical cancer caused by the HPV virus in various countries.

Abstract
Introduction: DNA Glycation damages DNA by inducing breaks of strands, mutations, and finally changes in gene expression, which is assumed as a main factor in pathogenesis of diabetes and its complications. Therefore, antiglycation agents have been focused recently for preventing and alleviating diabetes complications. According to the reported antidiabetic effects of Tamarix aphylla (T. aphylla) leaves extract, this study was aimed to determine the effect of T. aphylla on glucose-mediated DNA glycation for the first time.
Methods: DNA incubated with glucose for 4 weeks and the inhibitory or fascilitatory effects of T. aphylla on DNA structural changes were studied by various techniques. These techniques were included UV–Vis, fluorescence spectroscopy, circular dichroism (CD) and agarose gel electrophoresis.
Results: The findings of UV–Vis and fluorescence spectroscopy showed that T. aphylla decreased the DNA-AGE (advanced glycation end products) formation. Based on the CD and agarose gel electrophoresis results, the structural changes of glycated DNA was decreased in the presence of T. aphylla.
Conclusion: Thus T. aphylla has beneficial effects against DNA glycation and could be a promising agent for ameliorate the adverse effects of glycation in the presence of glucose and conditions of raised blood glucose after confirming in further studies.
