Effective DNA repair enables cancer cells to survive DNA damage induced by chemotherapeutic or radiotherapeutic treatments. Therefore, inhibiting DNA repair pathways is a promising therapeutic strategy for increasing the efficacy of such treatments. In this study, we found that dihydrocoumarin (DHC), a flavoring agent, causes deficiencies in double-stand break (DSB) repair and prolonged DNA dam...

Smith-Lemli-Opitz syndrome (SLOS) is a metabolic and developmental disorder caused by mutations in the gene encoding the enzyme 7-dehydrocholesterol reductase (Dhcr7). This reductase catalyzes the last step in cholesterol biosynthesis, and levels of 7-dehydrocholesterol (7-DHC), the substrate for this enzyme, are elevated in SLOS patients as a result of this defect. Our group has previously sho...

Faced with inherent inefficiencies built into transfer of a patient from emergency department (ED) to an inpatient bed, we determined that the timely availability of an inpatient bed was essential to improving efficiency and flow. Lack of beds early in the day was a major cause for delays and backup in the ED, which in turn placed the ED at risk for overcrowding and diversion. Review of the dis...

The formation of lipid electrophile-protein adducts is associated with many disorders that involve perturbations of cellular redox status. The identities of adducted proteins and the effects of adduction on protein function are mostly unknown and an increased understanding of these factors may help to define the pathogenesis of various human disorders involving oxidative stress. 7-Dehydrocholes...

زمینه و هدف: با توجه به افزایش تعداد سالمندان جامعه در سالهای اخیر و با در نظرگرفتن اینکه سلامت دهانی جزء تفکیک ناپذیری از سلامت عمومی این گروه از جامعه میباشد، در این مطالعه به ارزیابی وضعیت بهداشت دهان و دندان سالمندان مراجعه کننده به کلینیک خاتم الانبیاء (ص) شهر یزد در سال 1393 پرداخته شد. روش کار: در این مطالعه توصیفی مقطعی 251 نفر سالمندان بالای 60 سال مراجعه کننده به روش تصادفی ساده انتخا...

AIM Our previous works have demonstrated that Chinese herb medicine yanhusuo (Corydalis yanhusuo W. T. Wang) has strong anti-cancer proliferation effect in MDA-MB-231 cells. The goal of this study was to find out the synergic cytotoxicity effect of three natural compounds, tetrahydropalmatine (THP), berberine (Ber), and dehydrocorydaline (DHC), isolated from C. yanhusuo W. T. Wang. MATERIALS ...

5,8-Dihydroxycoumarin (5,8-DHC) was isolated from aerial parts of sweet grass (Hierochloë odorata L.) and screened for antioxidant and genotoxic activities. A clear linear dependency of radical scavenging capacity in DPPH• and ABTS•+ assays was determined. 5,8-DHC was very efficient in retarding rapeseed oil oxidation (Oxipress test). TPC (total phenols content) and FRAP (the ability to reduce ...

The hippocampus has a central role in learning and memory. Although once considered a relatively homogenous structure along the longitudinal axis, it has become clear that the rodent hippocampus can be anatomically and functionally divided into a dorsal component generally associated with spatial navigation, and a ventral component primarily associated with non-spatial functions that involve an...

1 2 The rodent hippocampus can be divided into dorsal (DHC) and ventral domains (VHC) 3 based on behavioral, anatomical, and biochemical differences. Recently, we reported 4 that CA1 pyramidal neurons from the VHC were intrinsically more excitable than DHC 5 neurons, but the specific ionic conductances contributing to this difference were not 6 determined. Here, we investigated the hyperpolariz...
