| 1 | Inoperable esophageal cancer and outcome of palliative care显示文摘AIM:To determine the outcome of esophageal cancer patients referred for palliative care,in Gorgan and Gonbad gastrointestinal clinics,northeast of Iran. METHODS:This cross-sectional study was done on inoperable esophageal cancer cases referred to gastrointestinal clinics in Gorgan and Gonbad city(2005-2006) . Demographic data were collected during the procedure and cases were followed up every one month. Improvement proportion was calculated with 95% confidence interval,to determine the rate of improvement. Survival analysis and Kaplan-Meier methods were used to estimate the duration of palliative care effectiveness. RESULTS:We recruited 39 cases into the study. Squamous cell carcinoma was the most prevalent(92.3%) . The middle third of the esophagus was involved predominantly(51.3%) . Dilation was the most preferred method(89.7%) and stenting was done in 4 cases. Decreasing dysphagia score was not related to palliation method or pathology type of carcinoma. Age of the patients was significantly related to the improvement of dysphagia score. Mean survival time was 137.6 d and median was 103 d. CONCLUSION:Results of this study showed a low survival rate after palliative care in esophageal cancer cases despite dysphagia scores' improvement after dilating or stenting. | Sima Besharat Ali Jabbari Shahryar Semnani Abbasali Keshtkar Jeran Marjani | 2008 | World Journal of Gastroenterology2008，14，23： | 5 |
| 2 | Spin-preserving chiral photonic crystal mirror显示文摘Chirality refers to a geometric phenomenon in which objects are not superimposable on their mirror image.Structures made of nanoscale chiral elements can exhibit chiroptical effects,such as dichroism for left-and right-handed circularly polarized light,which makes these structures highly suitable for applications ranging from quantum information processing and quantum optics to circular dichroism spectroscopy and molecular recognition.At the same time,strong chiroptical effects have been challenging to achieve even in synthetic optical media,and chiroptical effects for light with normal incidence have been speculated to be prohibited in thin,lossless quasi-two-dimensional structures.Here,we report an experimental realization of a giant chiroptical effect in a thin monolithic photonic crystal mirror.Unlike conventional mirrors,our mirror selectively reflects only one spin state of light while preserving its handedness,with a near-unity level of circular dichroism.The operational principle of the photonic crystal mirror relies on guided-mode resonance(GMR)with a simultaneous excitation of leaky transverse electric(TE-like)and transverse magnetic(TM-like)Bloch modes in the photonic crystal slab.Such modes are not reliant on the suppression of radiative losses through long-range destructive interference,and even small areas of the photonic crystal exhibit robust circular dichroism.Despite its simplicity,the mirror strongly outperforms earlier reported structures and,contrary to a prevailing notion,demonstrates that near-unity reflectivity contrast for opposite helicities is achievable in a quasi-two-dimensional structure. | Behrooz Semnani Jeremy Flannery Rubayet Al Maruf Michal Bajcsy | 2020 | Light(Science & Applications)2020，9，1： | 2 |
