These instruments are highly sensitive, and the gender of surgical instruments plays a critical role in how a surgeon performs in the operating room. Choosing the right type of instrument for each instrument requires considering many factors, including the type of surgery, the physical and chemical properties of the material, and the compatibility with the patient's body.

This study aimed to investigate the social support of patients, caregivers’ burden and their impact on the clinical course of the disease. Methods: The study included 85 patients with bipolar disorder type I and II (in the recovery phase of the disease) and their caregivers in the age range of 18 to 60 years. It was conducted in Shafa psychiatry Hospital in Rasht (Guilan, Iran, 2020). To assess social support and burden, patients and caregivers completed the Multidimensional Perceived Social Support Scale (MSPSS) and Caregiver Burden Inventory (CBI), respectively. Clinical variables were also obtained from patients’ medical records; Then ANOVA, MANOVA, Independent T-test were used to compare the data and Regression Analysis and Spearman correlation coefficient were used to find the relationships between variables. Results: It was showe...

Objective: The present study aims to investigate the prevalence of self-harm and deliberate self-cutting in high school students in northern Iran, and its relationship with anxiety, depression, and stress. Materials and Methods: In this analytical cross-sectional study, participants were 617 high school students in Rasht, Iran in 2018 who were selected through multistage cluster random sampling. Data collection tools were a demographic form, the Self-Harm Inventory (SHI), and the 21-item Depression, Anxiety, and Stress Scale (DASS-21). Data analysis was done by independent t-test, Kruskal–Wallis test, one-way analysis of variance, chi-square test, Fisher’s Exact test, and linear and logistic regression. Results: The mean age of students was 16.11±1.35 years, and the majority of them were male (64.2%). The prevalence of self-harm behaviors was 54....

For this disorder, weneed a proper assessment tool based on our indigenous culture. Objective: This study assesses the factor structure and psychometric properties of 10-item and 20-item Persian versions of Drug Abuse Screening Tests (DAST-10 and DAST-20). Materials and Methods: In this cross-sectional study, we randomly selected 200 participants referred to addiction treatment centers in Rasht City, Iran. After translation to Persian and back-translation to English, the face and content validity of DAST-10 and DAST-20 Persian versions were evaluated using the opinions of a panel of expertsand calculatingthe content validity ratio and content validity index. Then, the construct validity was evaluated by Confirmatory Factor Analysis(CFA), the Cronbach α coefficient was used for assessing internal consistency, and the Intraclass Correlation Coefficient (ICC) was used for assessing test-retest rel...

This was an in vitro study, in which the extraction of DNA from 30 samples of brain tissue was performed by phenol-chloroform protocols. After polymerase chain reaction (PCR) amplification of exon 8 of p53 genes, screening by single strand conformation polymorphism (SSCP) was performed to detect the shift. In this study, three malignant novel missense mutations in one sample with grade 4 of astrocytoma were detected. Also one synonymous mutation in grade 4 of astrocytoma was detected. The findings were indicated that mutations in exon 8 of the P53 gene mostly were in malignant astrocytoma brain tumor type, which is important in diagnosis and gene therapy of brain tumors.

To date, there is no known treatment to eradicate the disease and treatment strategies are often symptomatic. In this study, we review a medical report of a patient with HD and severe psychiatric symptoms treated by electroconvulsive therapy [ECT] Case report The patient is a 36-year-old man with Choreoathetoid movements and Psychiatric symptoms. As pharmacotherapy, had not significant effect Psychiatric and motor symptoms progressed. He treated with bitemporal ECT, Tetrabenazine and aripiprazole. Sessions of ECT had significant effect in treating psychiatric and movement symptoms. within 6 months’ follow-up, mood and psychiatric symptoms were controlled and motor symptoms were not worse. Conclusion ECT as an effective treatment in motor and psychiatric symptoms can be considered as first-line therapy that don’t have significant side effects and doesn’t ...

One therapeutic approach for diabetes treatment is decreasing postprandial glucose. Alpha-glucosidase and alpha-amylase Inhibitors normally use for controlling post prandial hyperglycemia in type 2 diabetic patients. Although acarbose and viglibose currently are used as αamylase and α-glucosidase inhibitors in the treatment of diabetes mellitus, but their side effects such as flatulence and diarrhea cause limitations for usage of these drugs. The aim of present study was to evaluate the α-glucosidase and alpha-amylase inhibitory potentials of Phoenix dactylifera, Capparis spinosa, Quercus brantii and Falcaria vulgaris. The most inhibitory effect on αglucosidase was detected by Q. branti with IC50=7.19 mg/ml. This plant also showed a significant effect on α-amylase inhibition with IC50=7.54 mg/ml. The most inhibitory effect on α-amylase was by P.dactylifera pollen grains with IC50=1.7 ...

On the other hand high blood pressure is a risk factor for stroke, heart disease, peripheral vascular disease and heart failure. There are several classes of pharmacological agents which have been used in the treatment of hypertension. Angiotensin I converting enzyme (ACE) Inhibitors are the important anti-hypertensive drugs. ACE catalyzes angiotensin I to angiotensin II and inactivates bradykinin. The synthetic ACE inhibitors are used widely to treat cardiovascular disorders. Because of their adverse effects such as cough, allergic reactions and skin rashes investigation for new natural sorces could be helpful. ACE inhibitory activity was measured according to the methods of Cushman and Cheung with some modifications. Hydroalcoholic extract of Ziziphora tenuior, Allium akaka, Allium haemanthoides, Allium hirtifolium were used. Captopril was use as positive control. ...
