    Abstract: In order to minimize pollution problems and to conserve limited natural resources, a hydrometallurgical procedure was developed in this study to recover the valuable resources of silicon (Si), silver (Ag) and aluminum (Al) from scrap silicon solar battery cells. In this study, several methods of leaching, crystallization, precipitation, electrolysis and replacement were employed to investigate the recovery efficiency of Ag and Al from defective monocrystalline silicon solar battery cells. The defective solar battery cells were ground into powder followed by composition analysis with inductively coupled plasma-atomic emission spectrometry. The target metals Ag and Al weight percentage were found to be 1.67 and 7.68 respectively. A leaching process was adopted with nitric acid (HNO 3 ), hydrochloric acid, sulfuric acid (H 2 SO 4 ) and sodium hydroxide as leaching reagent to recover Ag and Al from a ground solar battery cell. Aluminum was leached 100% with 18N H 2 SO 4 at 70°C and Ag was leached 100% with 6N HNO 3 . Pure Si of 100% was achieved from the leaching solution after the recovery of Ag and Al, and was analyzed by scanning electron microscope-energy dispersive spectroscopy. Aluminum was recovered by crystallization process and silver was recovered by precipitation, electrolysis and replacement processes. These processes were applied successfully in the recovery of valuable metal Ag of 98–100%.

    Abstract: This study aimed to compare the characteristics of patients with hematologic malignancies and solid cancers who received palliative care. A total of 124 patients with hematologic malignancy and 3032 patients with solid cancer, who received palliative care consultation services between 2006 and 2010 in a medical center in Taiwan, were retrospectively analyzed. Higher prevalence of oral stomatitis, diarrhea, and hematologic symptoms including infection, fever, severe anemia, and bleeding, and lower prevalence of constipation, abdominal distension, and pain were observed in patients with hematologic malignancies compared to that in patients with solid cancer. The interval from hospital admission to palliative care referral was longer for patients with hematologic malignancy than that for patients with solid cancer. Hematologists should refer patients earlier, and palliative care specialists should understand the specific needs of patients with hematologic malignancy.

    Abstract: There is controversy about the appropriate timing for renal replacement therapy in patients with acute kidney injury (AKI). We are interested in the appropriate timing for initiation of continuous renal replacement therapy in critically ill surgical patients with postoperative acute kidney injury. Seventy-three critically ill surgical patients with postoperative AKI who received continuous renal replacement therapy (CRRT) were enrolled. Indications for CRRT were: 1) AKI with hyperkalemia, 2) metabolic acidosis, 3) pulmonary edema refractory to diuretics, and 4) oliguria with progressive azotemia, especially in unstable hemodynamics. Using RIFLE (Risk, Injury, Failure, Loss, End stage) classification, patients who received CRRT in the “Risk” stage were defined as early group, whereas those in the “Injury/ Failure” stage were labeled as late group. We used continuous veno-venous hemofiltration as CRRT in this series. There were 20 patients in the early group and 53 patients in the late group. The mean ages were 61.5 ± 21.8 years versus 60.8 ± 17.5 years. The mortality rate was 50 per cent versus 84.9 per cent. There were no significant differences in demographic characteristics or type of surgery or physiological scores. Our data show that late initiation of CRRT is associated with a lower survival rate in critically ill surgical patients with postoperative AKI; however, further studies are required.

    Abstract: We retrospectively analyzed ABCG2 expression levels in patients with metastatic colorectal cancer (CRC) to investigate the interaction between ABCG2 expression and the tumor response to oxaliplatin and 5-fluorouracil (FOLFOX). Methods Forty-three patients with CRC with liver metastasis who received first-line FOLFOX treatment at our institution between 2008 and 2010 were enrolled. ABCG2 expression was assessed by immunohistochemistry. Tumor response was determined using the modified Response Evaluation Criteria in Solid Tumors criteria. Results At least 50% tumor shrinkage was observed in 16/43 patients (37.2%), including a complete response in 1 patient. According to the intensity of ABCG2 expression and the percentage of tumor cells expressing ABCG2, 21 tumors displayed high ABCG2 expression. Among these tumors, only 2 (9.5%) exhibited partial responses to FOLFOX; conversely, 63.6% of tumors with low ABCG2 expression (14/22) responded to FOLFOX. Primary and corresponding metastatic samples were available for 15 patients, and 13 of the metastatic tumors had higher ABCG2 expression than the corresponding primary tumors, but only 1 of these tumors responded to FOLFOX (7.7%). Conclusions ABCG2 expression is associated with the tumor response to FOLFOX in patients with metastatic CRC. ABCG2 may be a selective marker for the efficacy of FOLFOX in treating CRC.

    Abstract: Functional and structural disruptions to the pain matrix, which may involve changes in white matter (WM) pathways connecting the pain-processing system and hypothalamus, have been implicated in the pathophysiology of cluster headache (CH). However, previous studies have obtained inconclusive results regarding WM changes in CH, and WM variations between “in-bout” and “out-of-bout” periods of CH remain to be determined. Methods Multiple diffusivity indices obtained by diffusion tensor imaging (DTI) and post-hoc probabilistic tractography were used to elucidate CH pathophysiology. Results Compared to healthy participants, in-bout CH patients showed regionally higher absolute (radial and mean) diffusivities in the left medial frontal gyrus and frontal sub-gyrus and lower absolute (axial, radial and mean) diffusivities in the right parahippocampal gyrus of the limbic lobe. These changes during the in-bout period generally persisted in the out-of-bout period, except for the left cerebellar tonsil. Post-hoc probabilistic tractography showed highly consistent anatomical connections between these altered areas and the hypothalamus across participants. Conclusions Distinct WM changes were observed in episodic CH. Connections between the pain-modulation areas and hypothalamus may be involved in CH pathophysiology.

    SAGE Publications ; 2014

    Abstract: Silicon-based solar applications have tended towards the use of large, thin cells. However, an increased loss of materials occurs due to a high rate of destruction during the soldering and packaging processes. In this study, the effects of the presence of cracks on the thermal stress and stress intensity factor of the cells were explored for different aspect ratios of the soldering rods using an established finite element method. It was found that the residual stress in the cell was concentrated near the ends of the soldering rods, which coincided with the typical positions where breakage tended to occur on the cell. The residual stress on the cell increased with an increasing aspect ratio of the soldering rod. Cell damage due to cracking can be avoided by controlling the magnitude of the soldering rod’s aspect ratio.

    Abstract: Laparoscopic surgery is frequently applied in the operative management of appendicitis and symptomatic cholelithiasis because it is a minimally invasive procedure. There are, however, some complications of laparoscopic cholecystectomy (LC) and laparoscopic appendectomy (LA) that result in the need for reoperation. In the current study, we examine the effects of repeat laparoscopic surgery on the treatment of complications arising from LC/LA. From April 2005 to March 2011, we examined a cohort of patients who had received LC or LA and experienced complications that required reoperations. We focused on patients with postoperative hemorrhages, postoperative peritonitis, early postoperative small bowel obstructions (EPSBO), and biliary complications (after LC) who were treated through a repeat laparoscopic approach. The general demographics of the patients, their postoperative complications, procedures for selecting the appropriate reoperation method, and repeat laparoscopic findings are described in detail. During the 6-year period examined, 1608 patients received LC and 1486 patients received LA at the hospitals participating in this study. In patients with complications requiring reoperation, the repeat laparoscopic approach was performed successfully (without the need for further laparotomy) in 50 per cent of the patients with postoperative hemorrhage (2 of 4), 50 per cent of the patients with postoperative peritonitis (2 of 4), 75 per cent of the EPSBO patients (3 of 5), and 50 per cent the of patients with biliary complications (1 of 2). The repeat laparoscopic approach is an appropriate method for the management of complications arising from laparoscopic surgery. In patients with postoperative hemorrhage, laparoscopic hemostasis and hematoma evacuations can be performed while maintaining stable hemodynamics. In addition, laparoscopic approaches are also feasible for selective post-LC ductal injuries, EPSBO, and unconfirmed diagnoses of peritonitis after laparoscopic surgery.

    Abstract: The incidence of acute appendicitis in elderly patients is increasing due to prolonged life span. The associated morbidity and mortality related to perforation of acute appendicitis continue to present challenges to physicians. The role of laparoscopic appendectomy is still controversial. This study aimed to compare the postoperative outcomes of elderly patients who received either a laparoscopic or an open appendectomy. We retrospectively reviewed charts of patients with acute appendicitis between January 2005 and February 2009. Elderly patients who received laparoscopic or open appendectomies were enrolled. The demographics, preoperative condition, operating time, intraoperative blood loss, and postoperative course were analyzed. A total of 150 patients were enrolled in this study. On average, patients who received a laparoscopic appendectomy had fewer hospital days and lower rates of postoperative ventilator dependence than patients who received an open appendectomy. In the management of elderly patients with acute appendicitis, laparoscopic appendectomy provides better outcomes than open appendectomy.

    Abstract: Agomelatine is a new antidepressant with unique melatonin receptor type 1A (MTNR1A) and 1B ( MTNR1B) agonism and serotonergic receptor 5-hydroxytryptamine receptor 2C (5-HT-2C) antagonism. Several studies of patients with major depressive disorder (MDD) have confirmed the superior efficacy and safety of agomelatine in comparison with established treatments, such as selective serotonin reuptake inhibitors (SSRIs) or serotonin–norepinephrine reuptake inhibitors (SNRIs). This meta-analysis comprehensively shows the efficacy, acceptability, and safety of agomelatine in comparison with SSRIs and SNRIs used as antidepressants in MDD. Method: Comprehensive electronic database searches were performed to identify reports of head-to-head randomized controlled trials that have compared agomelatine with SSRIs or SNRIs in terms of efficacy/effectiveness in treating MDD. Response and remission rates at both acute (6–12 weeks) and follow-up (24 weeks) phases, Clinical Global Impression-Improvement Scale response and remission rates, changes in depression scale scores, improvements in subjective sleep, dropout rates, and side effect rates were extracted and analysed. Results: The meta-analysis included six head-to-head trials involving 1871 patients. In the acute phase, agomelatine had higher response rates (relative risk (RR) 1.08, 95% confidence interval (CI) 1.02–1.15) compared to SSRIs and SNRIs. In the remission analysis, only acute remission rates (RR 1.12, 95% CI 1.01–1.24) significantly differed. The action of agomelatine was superior on the Leeds Sleep Evaluation Questionnaire-Quality of Sleep score (mean difference 4.05, 95% CI 0.61–7.49). Discontinuation due to inefficacy did not differ between agomelatine and SSRIs/SNRIs (RR 0.74, 95% CI 0.42–1.28). Compared to SSRIs and SNRIs, however, agomelatine revealed a lower rate of discontinuation due to side effects (RR 0.38, 95% CI 0.25–0.57). Conclusions: Agomelatine has significantly higher efficacy and potential acceptability compared to SSRIs and SNRIs when treating MDD. However, the difference in efficacy is not considered clinically relevant. Because of its unique chronobiotic effects, agomelatine may be useful for the management of some MDD patients with circadian disturbance.
