dashte-mashhad reservoir provides the water supply needed for irrigating 120 acres of agricultural lands and also the soft water for people living in mashhad, chenaran, golbahar and a number of villages in the region. the deep wells of the region have been using the water stored in this reservoir since 1350 in a rate which exceeds that of water being imported to it, hence the decrement of the w...

the improvement in survival and local control measures in children with neoplasm in the head and neck region may lead to increased iatrogenic adverse effects of treatment. the aim of this study was to report a new case of the long-term effects of chemoradiotherapy on oral health and dental development in a patient treated for hodgkin's disease at an early age. in this case report, a 26-year-old...

statement of problem: microleakage is the most important factor in composite restorations failure, resulting in marginal degradation, marginal staining, secondary caries and pulp damage. one of the factors that influence microleakage is the method of caries removal. convention rotary instrumentation generates smear layer on the dental surface, whereas chemo-mechanical caries removal increases s...

background and objective: esophageal cancer especially squamous cell carcinoma (scc) is one of the most common gastro intestinal malignancies in north part of iran (khorasan). the standard treatment for esophageal cancer is surgical resection, but its outcome remains poor. then, the oncologists try to treat this cancer with sandwich protocols especially neo-adjuvant chemo-radiotherapy. several ...

Mesothelioma is inherently chemo-resistant with only 50% of patients responding to the standard of care treatments, and consequently it has a very grim prognosis. The aim of this study was to establish a panel of chemo-resistant mesothelioma models with clinically relevant levels of resistance as tools for investigating chemo-resistance and identifying new treatments for mesothelioma. Chemo-res...

In this researchsaccharomyces cerevisiae (baker’s yeast) was used as a cheap, readily accessible, selective, efficient, and green bio-catalyst in a chemo selective reduction of carbonyl group to hydroxyl group. In this green procedure three substrates e.g. (3-(3-nitrophenyl)aziridin-2-yl)-1-phenyl-methanone, pyruvate ester, and 2-acetyl-γ-butyrolactone were r...

In HIV-positive patients with non-Hodgkin lymphoma (NHL), no benefit of adding rituximab to chemotherapy was seen in a randomized controlled trial (RCT). We performed a meta-analysis of prospective studies to ascertain outcomes in HIV-positive NHL patients treated with chemotherapy (chemo) versus rituximab and chemo (R-chemo). A literature search through September 2011 was performed using the k...

Chemo—optical micro-sensing systems, whether based on fiber optics or integrated optics show promising prospects. The physical principles underlying chemo—optical waveguide sensors are discussed with the accent on linear evanescent field sensors. The role of the chemo-optical transduction layer is emphasized. Restriction of the freedom of design by technological uncertainties is briefly dealt w...
