Considering the increasing incidence and prevalence of coronary heart disease and the increasing emphasis of health researchers on the association and relationship of psychosocial factors with the occurrence and persistence of cardiovascular disease, the need to identify the desired factors and determine each of the personality and psychological factors. The effect is felt more than ever in patients who are also the target of the present study. The main purpose of this study was to determine the predictors of coronary heart disease based on personality types. Among cardiovascular patients, men and women aged 25-60 years in Shahid Madani and 29 Bahman hospitals in Tabriz, who were admitted to surgical wards for coronary angiography in 2015, 50 people were selected who met the inclusion criteria. Also, 50 patients were selected from the patients' companions and answered the questionnaires of Denollet type D personality and Ratus personality pattern questionnaire. Findings showed that the variables of negative emotions, social inhibition of the personality type D subscale were predictors of coronary heart disease. But the role of personality type A in predicting coronary heart disease is not significant. Social inhibition was also the strongest predictor of coronary heart disease. The present study showed that personality factors are predictors of coronary heart disease. Full article

Acute subdural hemorrhage caused by a ruptured intracranial aneurysm is a well-known association but usually linked to dismal outcome. We briefly reviewed the clinical and imaging features, surgical management and outcome of 45 patients with subdural bleeding related to intracranial aneurysm. Forty-two reports were encountered in the literature between 1981-2015 and three additional patients were identified in the author personal archives. A total of three patients had bilateral acute subdural hemorrhage, and the epidural hematoma was not present in any of the 45 reports. Coma was identified in 32/45 (71%) patients at admission. Only seven of 45 cases reported were managed by endovascular approach. A good clinical outcome was observed in 23/45 (51%) and early mortality occurred in 10/45 (22%) of the patients analysed. Neurosurgical management has evolved tremendously in recent years leading to more comprehensive understanding about this association. Factors leading to natural history, mechanisms, imaging aspects and improvement of clinical results of aneurysmatic subdural bleeding merit further studies.Full article

Introduction: Hypospadias repair is a challenging technique in pediatric urology with a long learning curve. This study presents the results of urethroplasty performed by a single surgeon to repair hypospadias in children and compares the surgical outcomes at different periods. Materials and Methods: From January 2009 to February 2016, patients who were less than 18 years old and were operated for hypospadias were retrospectively reviewed and divided into two groups: group I (from January 2009 to February 2012) and group II (from March 2012 to February 2016). All operations were performed by the same pediatric surgeon, and surgical outcomes of the two periods were compared. Results: This study considered150 patients (69 in group I/81 in group II). The Mean operative age was 30.4±32.7 months in group I and 33.6±43.3 months in group II(p=0.309). The selected procedures mainly depended on the subjective anatomical analysis in the operating room and the surgeon’s preference. The mean follow-up duration was 21.7±28.31 months in group I and 13.6±16.6 months in group II (p=0.033).The overall complication rate was 44.9% in group I and 35.8% in group II (p=0.316). The incidence of glanular disruption significantly decreased from 21.7% to 6.2% (p=0.007) because of the wide dissection of the glanular wings and the deep incision of the urethral plate, which led to tension-free sutures for glanular reconstruction. Conclusions: One-stage repair of hypospadias may achieve satisfactory outcomes in cosmetic appearance and voiding function. Surgical outcomes could be improved by increasing practice.Full article

Introduction: Liver and kidney affection is a life-threatening disease caused by factors including drug-based treatment. Treatment based on methotrexate could result in liver and kidney damages. The study evaluates the preventive effects of Sorindeia juglandifolia leaves on methotrexate-induced liver and kidney impairment in rat. Methods: Healthy rats divided into 6 groups daily received distilled water, methotrexate (20 mg/kg), sub-cutaneous injection of L-carnitin (500 mg/kg) and methotrexate and the plant extract doses of 150, 250 and 350 mg/kg and methotrexate for 10 days. During treatment, body weight was recorded. At the end of the treatment, animals were sacrificed; venous blood were collected for haematological and biochemical analysis. Liver and kidney were collected for oxidative markers and histological examination. Results: The consecutive treatment of animals with plant extract and methotrexate showed a significant prevention of the body weight decrease and enhancement of the relative weight of liver and kidney. Sorindeia. juglandifolia extract also protected from the significant increase in transaminase activities, bilirubin and protein level, hypercholesterolemia, atherogenic index, and in the kidney from hypercreatininemia and the increase in serum urea level. The extract prevented the decrease of sodium level and glomerular filtration. Plant extract improved reactive oxygen species detoxification agents and protected from the histological disorganization of the liver and kidney tissues, observed in the MTX control. Conclusion: Sorindeia juglandifolia leaves extract expressed hepatorenal protective properties and could be useful to prevent liver and kidney damage induce by methotrexate.Full article

Background and objective: Glioblastoma (GBM) is one of the malignant tumors causing death worldwide. Most patients were found in the middle and late stages and had poor prognosis. The purpose of this study was to investigate the expression and significance of CTSC in GBM. Methods: The information about CTSC in Oncomine database was collected and analyzed twice. The role of CTSC in GBM was meta-analyzed. The expression of CTSC in glioma cell lines was retrieved by CCLE database, and the survival of patients was analyzed by TCGA database. Results: A total of 1,459 different types of CTSC were collected in Oncomine database, 134 of which had statistical differences in CTSC expression, 89 of which had increased CTSC expression and 45 of which had decreased CTSC expression. A total of 50 studies involving the expression of CTSC in GBM cancer and normal tissues included 1,189 samples. Compared with the control group, CTSC was highly expressed in GBM (P < 0.05). Moreover, CTSC was highly expressed in glioma cell lines. There was a correlation between the expression of CTSC and the overall survival rate of GBM. The overall survival rate of patients with high expression of CTSC was worse, while the prognosis of patients with low expression of CTSC was better (P < 0.05). Conclusion: Through the in-depth mining of oncomine gene chip database, we propose that CTSC is highly expressed in GBM tissues and is related to the prognosis of GBM, which may provide an important theoretical basis for the treatment of glioma..Full article

Abiotic stress especially due heavy metals is one of the major environmental problems that threatens food security and pose greater risks to human health worldwide. In this research, greenhouse hydroponic experiments were carried out to study the morphological and biochemical responses of Sorghum bicolor L.M to different Zinc (Zn) levels. Two-week-old seedlings transplanted in hydroponic solutions were treated with different doses of Zn in the concentration ranges of 5, 25, 50, 100 and 200 mg/L supplied as ZnSO4. 5H2O. After 21 day of culture, the plants were harvested, blotted to dryness and separated into roots and shoots. The root and shoot lengths, dry weights and non-enzymatic biochemical parameters such as proline, Chlorophyll a, b, Carotenoids (pigments) were determined. The results indicate that Zn applications significantly (P<0.05) depressed the lengths of root and shoot, dry weights and pigment contents compared to untreated plants (control). The effects were more pronounced with increased Zn dosage. The accumulation of the metal and proline contents in treated plants however, increase gradually with increasing Zn concentrations (P<0.05). The changes in these parameters had resulted in toxicity symptoms and overall growth retardation especially at elevated concentrations and the estimated critical toxicity thresholds in both solution and tissue concentrations suggest that sorghum bicolor L.M should not be grown beyond Zn concentration of above 3.2 mg/L.Full article

Objective: This study aimed to determine whether perioperative antiviral treatment is facilitate for patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) and Child-Pugh grade A cirrhosis in perioperative recovery of liver function and HBV activation. Methods: The study included 115 patients with HBV-related HCC and Child-Pugh grade A cirrhosis who underwent resection. Patients were prospectively assigned to a preoperative antiviral treatment group (n = 51) or postoperative antiviral treatment group (n = 52); twelve patients who had not received antiviral treatment before and after surgery were designated a non-treatment group (n = 12). HBV reactivation during a month after the operation was defined as a HBV DNA value tenfold over preoperative values. Postoperative liver dysfunction was defined as prothrombin activity <50% and serum bilirubin >50 mmol/L on postoperative day 5. Results: Postoperatively, liver dysfunction was present in 1 of 51 (1.96%) patients who received preoperative antiviral therapy, 1 of 52 (1.92%) who received postoperative therapy, and 3 of 12 (25%) who received no antiviral therapy. HBV reactivation postoperatively occurred at similar rates. Conclusions: Preoperative and postoperative antiviral treatment of patients with Child-Pugh grade A cirrhosis and high levels of HBV DNA undergoing hepatic resection for HCC are both facilitate in preventing perioperative liver dysfunction and reactivation of HBV. Thus, in this population with high levels of HBV DNA, perioperative antiviral treatment is important.Full article

Human immunodeficiency virus (HIV) infection is associated with an increased risk for Viral infections such as Epstein-Barr virus (EBV)infections also known as Human Herpes Virus Type 4 (HHV-4) and their related diseases which frequently cause malignancy related diseases resulting to poor treatment and health outcomes. In this study, we determined the seroprevalence of EBV VCA IgM antibodies among HIV patients attending Plateau Specialist Hospital, Jos, Nigeria and to evaluate their association with age, sex as well as other demographic factors. A total of 92 HIV positive patients were enrolled and serum samples were screened for antibodies using the ELISA kit. The prevalence of EBV VCA IgM was 6/92(6.53%), and mean age of 37.48 ±1.01 years. This study has contributed to baseline data, and suggest the need for larger studies and importance of screening and treatment of EBV among HIV patients.Full article
