Abstract
Background & Objectives: Different types of diets and several chemical and herbal drugs are used for decreasing the fasting blood glucose, glycosylated hemoglobin and insulin resistance in type II diabetic patients. New herbal medicines including cinnamon have been considered for controlling diabetes. Since few reports have been presented in other countries and many studies have been done in animal models in laboratory condition, this study was aimed to investigate cinnamon supplementation effects on fasting blood glucose, glycosylated hemoglobin and insulin resistance among type II diabetic patients . Methods: In a clinical trial study, 60 male and female patients with type II diabetes mellitus (30 patients in control and 30 patients in treatment group) were selected in Tabriz city, during 1388. The intervention group received 1.5 g of cinnamon (as a capsule containing 500 mg powder, three times daily) for 60 days and control group received placebo. Blood samples obtained from patients to determine the levels of fasting blood glucose, the glycosylated hemoglobin and insulin, before and after cinnamon consumption. Insulin resistance was measured by HOMA score and data were expressed as Mean ± SD and analyzed statistically by Student t-test. p<0.05 was considered as significant . Results: After 60 days, the fasting blood glucose levels, the glycosylated hemoglobin and the insulin resistance decreased significantly in the intervention group compared to controls (p<0.05). There was no significant change in the fasting blood glucose levels, the glycosylated hemoglobin and the insulin resistance in the control group at the end of 60 days. Conclusion: This study showed the consumption of cinnamon can be useful in the fasting blood glucose, the glycosylated hemoglobin and the insulin resistance control among type II diabetic patients .

Abstract
Background: Co-inheritance of hemoglobin gene defects is a rare important status that can lead to double heterozygote or homozygote with significant clinical manifestations. Such conditions can be observed in co-inheritance of alpha-thalassemia with beta-thalassemia or hemoglobinopathy. The aim of this study was to evaluate the prevalence of alpha-thalassemia with beta-thalassemia and hemoglobinopathy co-inheritance in a considerable number of Iranian. Methods: This descriptive study was performed on patients with abnormal hematological findings in favor of alpha-thalassemia, beta-thalassemia or beta-hemoglobinopathies. Patients with low MCV and MCH levels and high HbA2 (>3.5) and those with low MCV and MCH and normal or low HbA2 were candidate for molecular analysis for beta and alpha thalassemia respectively. Abnormal Hb electrophoresis was diagnostic criteria for molecular analysis of beta-hemoglobinopathies. Results: Study revealed that more than half of the patients with alpha-thalassemia affected simultaneously by beta-thalassemia and about thirty percent inherited beta-hemoglobinopathies. Among patients with beta-thalassemia, HbSCd6 (A-T) was the most common mutation and in alpha-thalassemic patients α 3.7 was the commonest mutation. Conclusion: Relatively high prevalence of co-inheritance of alfa-thalassemia with beta-thalassemia and hemoglobinopathies reflect the necessity of genetic consulting and molecular analysis in diagnosis of such conditions.

Abstract
Background & objectives: This study was designed to compare the effect of general and spinal anesthesia on hemoglobin and hematocrit values in women following cesarean section.
Methods: This clinical trial study performed on 88 ASA class 1 pregnant women who were candidate for elective cesarean. Forty six patients received general anesthesia with isoflorane 0.75, N2O 50% and O2 and also 42 patients received spinal anesthesia with 12 mg of bupivacaine. The patients with a systemic disease or other causes of intraoperative excessive bleeding were excluded. All the operations were performed by same surgeon. Pre- and post-operative Hb and HCT values and Apgar score were recorded in both groups.
Results: Previous cesarean section history was the cause of surgery in 21 patients in group one and 22 patients in group two. Both groups were similar in age, weight, height and parity. The preoperative mean Hb or HCT values did not differ significantly between two groups. In both groups, postoperative mean Hb and HCT values were decreased significantly. Postoperative Hb and Hct reduction was significantly higher in general anesthesia group (p<0.05). There was no significant difference between two groups regarding Apgar score.
Conclusion: This study showed higher postoperative Hb and Hct reduction in general anesthesia than spinal anesthesia.

Abstract
Background & objectives: Zinc sulfate binds to the R group of some amino acids, such as histidine and cysteine, resulting in protein precipitation. In an ELISA and colorimetric experiments, we determined the optimal concentration of zinc sulfate to precipitate hemoglobin, which in turn affects the level and activity of Caspase 3 in red blood cells.
Methods: Osmotic stress was induced on red blood cells under hypertonic and hypotonic conditions. An isotonic condition was used as a control without osmotic stress. The cells were incubated at 37oC for 15 min and 24 hrs. Different concentrations of zinc sulfate were set up experimentally, stepwise after the lysis of RBC samples with ultrasound waves and removal of cell membranes by centrifugation. Zinc sulfate was allowed to bind to hemoglobin at different time intervals at room temperature. Afterward, hemoglobin was precipitated at various time intervals through centrifugation. The supernatants were then measured by ELISA and colorimetric methods for Caspase 3 level and activity.
Results: The optimal conditions were found to be 6 mM zinc sulfate, 10 min incubation at room temperature to bind zinc sulfate to hemoglobin, and 30 min centrifugation at 3000 rpm to precipitate hemoglobin.
Conclusion: This study showed that zinc sulfate with a concentration of 6 mM precipitates and removes hemoglobin without affecting the level or activity of Caspase 3.

Abstract
Background: Diabetes is a significant risk factor for postoperative complications and mortality. However, there are different opinions about the relationship between the increase in glycosylated hemoglobin (HbA1c) level and the incidence of surgical complications.
Methods: In this retrospective study, 189 diabetic patients referred to Sabalan Hospital in Ardabil who were admitted for surgery were examined in 2021. The data related to demographic information, HbA1c test, postoperative complications, and the outcome of patients’ hospitalization were extracted from the records and entered into the researcher-made checklist. Patients were divided into two groups of uncontrolled diabetes with HbA1c of 7 and above and the controlled diabetes group with HbA1c below 7.
Results: Out of 189 patients included in the study, 97 patients were in the uncontrolled diabetes group, and 92 patients were in the controlled diabetes group. The average age of diabetic patients in uncontrolled and controlled diabetes groups was 58.18±8.91 and 61.84±5.52, respectively. According to the results, surgical site infection and the need for re-surgery during hospitalization showed a significant relationship with an HbA1c level (p≤0.05). Other postoperative complications were not significantly different between the two groups.
Conclusion: It seems logical that elective surgeries should be postponed in HbA1c levels higher than 7% because the presence of high HbA1c levels indicates that the patient’s diabetes is not under control, and as a result, there is a higher probability of chronic complications of diabetes as well as a higher risk for post-operative complications.

Abstract
Background: Determining the concentration of hydrogen peroxide in liquids and biological samples is very important because of its effects on human health. This study aimed to design a new electrochemical biosensor based on hemoglobin to detect hydrogen peroxide in serum samples.
Methods: In this study, a basic science, a biosensor based on modifying the glassy carbon electrode surface with a nanocomposite consisting of cobalt oxide nanoparticles and multi-walled carbon nanotube functionalized with a carboxyl group (MWCNT/Co3O4) and hemoglobin stabilized on this nanocomposite was made as a biological recognition element.
Results: In optimal conditions, the biosensor was used to measure different concentrations of hydrogen peroxide. The designed biosensor showed a wide linear response range from 10 μM to 500 μM, a detection limit of 0.512 μM, and high reproducibility and stability.
Conclusion: In this innovative research work, MWCNTs/Co3O4 nanocomposite was used to make a diagnostic biosensor. The presented biosensor showed an acceptable performance in the measurement of hydrogen peroxide in serum samples and laboratory solutions.
