Two new sesquiterpene coumarins, named szowitsiacoumarin A (1) and szowitsiacoumarin B (2), and a phenylpropanoid derivative, 2-epihelmanticine (3), together with nine known compounds, auraptene (4), umbelliprenin (5), galbanic acid (6), methyl galbanate (7), farnesiferol B (8), farnesiferol C (9), persicasulfide A (10), beta-sitosterol and stigmasterol(More)
Monitoring of myoglobin (Mb) in human blood serum is highly in demand for early diagnosis of acute myocardial infarction (AMI). Here, a novel electrochemical aptasensor was developed for ultrasensitive and selective detection of Mb, based on Y-shape structure of dual-aptamer (DApt)-complementary strand of aptamer (CS) conjugate, gold electrode and(More)
AIM Single-walled carbon nanotubes (SWNTs) have been already used as drug carriers. In this study, we introduced sgc8c aptamer (this aptamer targets leukemia biomarker protein tyrosine kinase-7) to complex between Dau (daunorubicin) and SWNT to enhance targeted delivery of Dau to acute lymphoblastic leukemia T-cells (Molt-4). MATERIAL AND METHODS(More)
The objective of this study was to evaluate the relationship between Enterobius vermicularis and the occurrence of acute appendicitis. Over a ten year period of time, all appendix specimens received by the department of pathology were reviewed for pathologic changes and the existence of E. vermicularis. Logistic regression was carried out to determine the(More)
Antinociceptive, anti-inflammatory and acute toxicity of the aqueous infusion and ethanolic maceration extracts of the aerial parts of Zataria multiflora Boiss were studied in mice and rats. Antinociceptive activity was done using hot-plate and writhing tests. The effect of the extracts against acute inflammation was studied by vascular permeability(More)
BACKGROUND The aim of this study was to determine the cumulative prevalence rate of every sexual dysfunctions (SDs) in Iranian population. METHODS We searched international database such as: PubMed/Medline, Scopus, PsychNET, and Scholar Google and Iranian database such as Iran Psych, IranDoc, IranMedex, and SID. Search duration was between 1990 and 2013.(More)
In this study, a series of alkyl-oligoamine derivatives of low-toxicity 10 kDa polyethylenimine (PEI) were synthesized to enhance the hydrophobicity of PEI while preserving most of its primary amine content. PEI was reacted with a series of omega-bromoalkylcarboxylic acids with different chain lengths (2-bromoacetic, 6-bromohexanoic, 10-bromodecanoic and(More)
The antinociceptive effect of different Elaeagnus angustifolia fruit seed extractives was studied in mice using hot-plate and writhing tests. Following intraperitoneal injection, the decoction (EaDE), the ethanol extract (EaEE), the aqueous and n-butanol fractions (EaAF, and EaBF, respectively) of a polyphenolic fraction, and two flavonoid-enriched(More)
Every year a large number of new cases of colorectal cancer are diagnosed in the world. Application of Epirubicin (Epi) in treatment of cancer has been limited due to its cardiotoxicity. Specific delivery of chemotherapy drugs is an important factor in reducing the side effects of drugs used in chemotherapy. Enhanced permeability, retention effect and(More)
To determine the relationship between socioeconomic status (SES) and cardiovascular disease (CVD) risk factors. A representative sample of adult populations living in three cities in Iran was studied. The demographic and subjective data were collected by questionnaires prepared and validated for this study; physical examination and laboratory tests were(More)
