in this study, cross linked chitosan resin (ccr) was prepared by cross linking chitosan with glutaraldehyde, and then î±-ketoglutaric acid-modified chitosan resin (kcr) was obtained by modifying ccr with î±-ketoglutaric acid. the sorption behavior of methylene blue (mb) on kcr and ccr from aqueous solution was investigated. the effect of various experimental parameters (e.g. initial ph, sorbent...

BACKGROUND Children who stutter (CWS) are at a high-risk of being teased and bullied in primary school because of negative peer attitudes and perceptions towards stuttering. There is little evidence to determine if classroom-based interventions are effective in changing peer attitudes towards stuttering. The primary objective is to determine the effect of the Classroom Communication Resource (C...

Background: Gastric cancer patients usually suffer from skeletal muscle depletion. The serum creatinine/cystatin C ratio (CCR) is a new, simple tool that could serve as biomarker of mass. This study explored the ability preoperative CCR to predict postoperative complications in with gastric cancer.

This paper introduces a new methodology ensuring units invariant slack selection in radial DEA models and incorporating the slacks into an overall efficiency score. The CCR and BCC models are units invariant in their radial component, but not in their slack component, thus changing the units of measurement of one or more variables can change the models’ solution. The proposed Full Proportional ...

Aflibercept, an intravenously administered anti-VEGF and antiplacental growth factor (PlGF) agent, has recently been approved by the U.S. Food and Drug Administration in combination with 5-fluorouracil, leucovorin, and irinotecan (FOLFIRI) for the treatment of patients with metastatic colorectal cancer who have previously received an oxaliplatin-containing chemotherapy regimen. In the phase III...

I introduce yet another way to associate a C*-algebra to a graph and construct a simple nuclear C*-algebra that has irreducible representations both on a separable and a nonseparable Hilbert space. Kishimoto, Ozawa and Sakai have proved in [8] that the pure state space of every separable simple C*-algebra is homogeneous in the sense that for every two pure states φ and ψ there is an automorphis...

Download creatic cancer (PC) is a highly lethal disease with complex etiology involving both environmental netic factors. Although cigarette smoking is known to explain 25% of cases, data from recent studies sugat obesity and long-term type II diabetes are twomajor modifiable risk factors for PC. Furthermore, obed diabetes seem to affect the clinical outcome of patients with PC. Understanding t...

Sepsis is a common post-operative complication, which may account for one-third of all cases of sepsis.1 Patients who develop sepsis during or after surgery can progress to multiple organ dysfunction, and have a signifi cantly greater mortality rate during their hospital stay.2-4 The cost of treating such patients was estimated as three times higher than treating surgical patients without posto...
