Predicting Factors of Complete Pathological Response in Locally Advanced Rectal Cancer.

: Current treatment of choice for locally advanced rectal cancer is neoadjuvant chemoradiotherapy (neo-CRT) followed by surgical resection and adjuvant chemotherapy. Some patients may experience complete pathological response (cPR) after the neoadjuvant treatment. However, the predicting factors are still debated.

Nano-hydroxyapatite could Compensate the Adverse Effect of soft carbonated Drinks on Enamel.

Introduction: Since one of the most important disadvantages of soft drinks includes their adverse effect on mineral content of enamel because of their low pH, this study examined the microhardness of enamel before and after exposure to a soft drink containing different concentrations of nano-hydroxyapatite (nano-HA) as an additive.

Materials And Methods: Sixty caries free human premolars were mounted in epoxy resin. After polishing, the baseline micro-hardness was recorded three times for each specimen using a Vickers indenter at 50 gm load.

Assessment of a Hospital Palliative Care Unit (HPCU) for Cancer Patients; A Conceptual Framework.

Introduction: The first hospital palliative care unit (HPCU) in Iran (FARS-HPCU) has been established in 2008 in the Cancer Institute, which is the largest referral cancer center in the country. We attempted to assess the performance of the HPCU based on a comprehensive conceptual framework. The main aim of this study was to develop a conceptual framework for assessment of the HPCU performances through designing a value chain in line with the goals and the main processes (core and support).

Effect of Nano-Tricalcium Phosphate and Nanohydroxyapatite on the Staining Susceptibility of Bleached Enamel.

Objective. This study was designed to evaluate the effect of nano-tricalcium phosphate (n-TCP) and nanohydroxyapatite (n-HAP) on prevention of restaining of enamel after dental bleaching. Methods.

Situation analysis of the National Comprehensive Cancer Control Program (2013) in the I. R. of Iran; assessment and recommendations based on the IAEA imPACT mission.

Introduction: Iran was engaged in the Program of Action for Cancer Therapy (PACT) in 2012, and delegates from the International Atomic Energy Agency (IAEA), and the World Health Organization (WHO) evaluated the National Cancer Control Program (NCCP) status (the imPACT mission), based on which they provided recommendations for improvements of NCCP in the I.R. of Iran.
