A biodegradable poly(L-lactic acid) (PLLA) macroporous scaffold with a regular and highly interconnected structure in the size range from 50 to 150 mu m was fabricated PLLA--dioxane--water ternary system use of thermally induced phase separation (TIPS) process. The diagram PLLA molecular weight above 200,000 measured. It found that small change water content solvent caused large shift cloud-point temperature. porous morphology closely related quenching route formulation parameters, including...
Abstract The pristine lignin molecules contain multiple reactive hydroxyl [OH] groups, some of which undergo limited polymerization depending on their configuration (aromatic or aliphatic) conformation. key issue in lignin-polymerization is to quantify the number groups for subsequent activation specific lignin-polymer chain lengths degree grafting. In this study, using ε-caprolactone (CL) as a solvent, we successfully polymerized CL sites kraft macromonomers (LM, M w = 1,520 g mol −1 ),...
In Brief Background This study aimed to evaluate risk factors and postoperative clinical outcome associated with myocardial injury detected by an elevated high-sensitivity cardiac troponin I (hs-cTnI) immediately after living donor liver transplantation (LDLT). Methods Between January 2011 December 2016, 313 adult recipients undergoing LDLT, normal preoperative hs-cTnI were selected. Hs-cTnI level above 0.04 ng/mL according 99th percentile reference limit was defined as injury. The divided...
Background There is a need for investigating the analgesic method as part of early recovery after surgery tailored laparoscopic colorectal cancer (LCRC) surgery. In this randomized trial, we aimed to investigate efficacy an inverse 'v' shaped bilateral, subfascial ropivacaine continuous infusion in LCRC Methods Forty two patients undergoing elective were randomly allocated one groups receive either 0.5% at plane (n = 20, R group) or fentanyl intravenous patient controlled analgesia (IV PCA)...
The solvation free energy density (SFED) model was modified to extend its applicability and predictability. parametrization process performed with a large, diverse set of energies that included highly polar ionic molecules. mean absolute error for 1200 the 379 neutral molecules in 9 organic solvents water 0.40 kcal/mol, 90 hydration ions 1.7 kcal/mol. Overall, calculated wide range solute functional groups were consistent experimental data.
Placing a double-lumen endobronchial tube (DLT) in an appropriate position to facilitate lung isolation is essential for thoracic procedures. The novel ANKOR DLT developed with three cuffs newly added carinal cuff designed prevent further advancement by being blocked the carina when inflated. In this prospective study, direction and depth of initial placement were compared those conventional DLT. Patients undergoing surgery (n = 190) one-lung ventilation (OLV) randomly allocated into either...
The most common method of monitoring cardiac output (CO) is thermodilution using pulmonary artery catheter (PAC), but this associated with complications. Impedance cardiography (ICG) a non-invasive CO technique. This study compared the accuracy and efficacy ICG as function technique to those arterial pressure contour.Sixteen patients undergoing liver transplantation were included. Cardiac index (CI) was measured by PAC, waveform analysis, simultaneously in each patient. Statistical analysis...
Green discoloration of the urine after propofol administration is a rare clinical phenomenon. Although exact incidence propofol-induced green not known, reported thought to be less than 1%. In most cases urine, effects were benign and reversible. However, many clinicians are unfamiliar with this side effect propofol. Here, we present case patient who showed following two-staged repair thoracoabdominal aortic aneurysm infusion. His had normal yellowish color first operation, but appeared...

Background With the increasing demand for general anesthesia endoscopic esophageal procedures, anesthesiologists should understand clinical characteristics of post-procedural complications (PPCs). Methods We retrospectively investigated incidence and risk factors associated with PPCs procedures performed under from July 2013 to November 2016. The final analysis included 129 patients; 114 who underwent dissection tumors 15 cases peroral myotomy achalasia. Frank perforation during procedure...
We developed inverted red quantum dot light-emitting diodes (QLEDs) with ZnO nanoparticles synthesized in open and closed systems. Wurtzite-structured were using potassium hydroxide zinc acetate dihydrate at various temperatures the The particle size increases increasing synthesis temperature. 50, 60, 70 °C system have an average of 3.2, 4.0, 5.4 nm, respectively. is larger compared to as methanol solvent evaporates during process. surface defect-induced emission shifts a longer wavelength...
In the recent semiconductor industry, as device shrinks, spin-on dielectric (SOD) has been adopted a widely used material because of its excellent gap-fill, efficient throughput on mass production and highly competitive initial cost ownership. Among various applications, SOD is especially valued suitable gap-fill for shallow trench isolation (STI), previously technology, high density plasma chemical vapor deposition (HDP-CVD), significant problem with void-free patterns aspect ratios. As...
Endoscopic submucosal dissection (ESD) is widely performed these days as the standard procedure for treatment of early gastric cancer. During ESD, insertion and rotation scope, air insufflation, incision hemostasis may provoke pain, which commonly requires either general anesthesia or moderate to deep sedation. Deep sedation precludes need anesthesia, can help endoscopists speed up compared light But, there are risks respiratory complication. We report a case compromise caused by...
