The prevalence of allergic rhinitis and atopic eczema is on the rise in recent decades. Many factors can be related to the development of these diseases. We aimed to investigate the association between socioeconomic status (SES), environmental risk factors and these conditions. In this study, the International Study of Asthma and Allergies in Childhood(More)
Human genome sequencing revealed that only ~1.5% of the DNA sequence coded for proteins. More and more evidence has uncovered that a substantial part of the 98.5% so-called "junk" DNAs actually code for noncoding RNAs. Two milestones, chemical drugs and protein drugs, have already appeared in the history of drug development, and it is expected that the(More)
New resveratrol (RES) analogs were developed by replacing the aromatic 'core' of our initial naphthalene-based RES analogs with pseudo-heterocyclic (salicylaldoxime) or heterocyclic (benzofuran, quinoline, and benzothiazole) scaffolds. The resulting analogs were tested for their antiproliferative and vasorelaxing effect, two typical properties shown by RES.(More)
BACKGROUND Hemorrhoid is one of the most common surgical diseases occurring in the anorectal region. In this study, we evaluated the effect of ischiorectal fossa block on alleviating post hemorrhoidectomy pain. METHODS In this study, 90 patients suffering from hemorrhoids were evaluated. They were randomly divided into 3 groups. The first group had no(More)
Dimethyl-5-acetyl-4-methyl-6-(4-methylphenylimino)-6H-thiopyran-2,3-dicarboxylate (4) has been synthesized and its antiproliferative activity is reported here. Compound 4 inhibited the growth of human colon cancer cell line HCT-15 with an IC(50) value of 3.5 μM and of breast cancer cell line MCF-7 with an IC(50) value of 1.5 μM in a dose/time-dependent(More)
N(6)-Isopentenyladenosine (iPA), a member of the cytokinin family of plant hormones, exerts remarkable inhibition on tumor cell proliferation and apoptosis in several tumor cell lines. In this study, we report that iPA is able to inhibit the proliferation and promotes apoptosis in HCT-15 human colon cancer cells in a dose-dependent manner with a(More)
The antiproliferative activity of 2-(3,5-Dihydroxyphenyl)-6-hydroxybenzothiazole (DHB) is reported here. DHB inhibits the growth of human colon cancer HCT-15 with a 50% cell growth inhibition value of 23 μM and breast cancer MCF-7 with a 50% cell growth inhibition value of 41 μM in a dose/time dependent manner by using sulforhodamine B assay. Cell cycle(More)
N(6)-Isopentenyladenosine (iPA) is a member of the cytokinins, a family of plant hormones that regulate plant cell growth and differentiation. iPA is present in mammalian cells in a free form, as a mononucleotide in the cytoplasm, or in a tRNA-bound form. Its antiproliferative activity against cancer cells lines has been reported by several authors. We show(More)
Flavonoids have recently attracted a great interest as potential therapeutic drugs against a wide range of free-radical-mediated diseases. The anticancer and antiviral activities of these natural products are implicated in their mechanism of actions. While the antioxidant activity of these natural polyphenolic compounds is well known, their bindings to DNA(More)
Resistance to antibiotics is a major public-health concern and antibiotic use is being ever more recognized as the main discriminatory pressure driving this resistance. The aim was to assess the outpatient usage of antibiotics in teaching hospitals in various parts of capital city of Iran, Tehran and its association with resistance. 600 outpatient(More)
