Background: It is reported that the percentage of smudge cells in the blood smear could be a prognostic indicator in chronic lymphocytic leukemia. However, the clinical significance of smudge cells in other hematological malignancies, solid tumors or non-malignant diseases is less clear. Hence, this study was conducted to survey the clinical significance of smudge cells in hematological cancers and other disorders. Materials and Methods: From January to November, 2015, the clinical data of patients who received blood examination with differential counts for clinical purpose and were found to have smudge cells in the peripheral blood film in Far Eastern Memorial Hospital were selected. The percentage of smudge cells and patient outcomes were evaluated for further univariate and survival analyses. Results: A total of 102 patients with smudge cells in their blood smears were included. Smudge cells were frequently presented in out-of-hospital cardiac arrest (OHCA; n=30), infections (n=23), hematological cancers (n=23) and solid cancers (n=10). There was no relationship between the percentage of smudge cells and the patient mortality in all diseases (OR: 1.08, 95% CI: 0.47-2.48, P=1.000) as well as the OHCA group (OR: 1.91, 95% CI: 0.38-9.60, P=0.694). It was observed that in patients with all cancers with the percentage of smudge cells less than 50% had a lower mortality rate in comparison with those who had the percentage of smudge cells of 50% or more (OR: 22.29, 95% CI: 2.38-208.80, P<0.001). Additionally, it was seemingly that patients with smudge cells of 50% or more had a lower survival rate than those with smudge cells less than 50% in all cancers with follow-up at 2-month intervals, but without statistical significance (P=0.064). Conclusions: Our survey indicated that in all cancers, those who had higher percentage of smudge cells were prone to have poor outcomes when compared with the subjects with lower percentage of smudge cells. This finding was quite different from the results of previous studies in which the race-ethnicity of most study populations was non-Asian; hence, further investigations are required. Besides, there was no apparent association of the percentage of smudge cells with patient outcomes in all diseases, including OHCA.

A series of Fe-Cr-C hardfacing alloys is deposited by gas tungsten arc welding and subjected to abrasive wear testing. Pure Fe with various amounts of CrC (Cr:C=4:1) powders are mixed as the fillers and used to deposit hardfacing alloys on low carbon steel. Depending on the various CrC additions to the alloy fillers,the claddings mainly contain hypoeutectic, near eutectic, or hypereutectic microstructures of austenite γ-Fe phase and (Cr,Fe)7C3 carbides on hardfacing alloys, respectively. When 30% CrC is added to the filler, the finest microstructure is achieved, which corresponds to the γ-Fe+(Cr,Fe)7C3 eutectic structure. With the addition of 35% and 40% CrC to the fillers, the results show that the cladding consists of the massive primary (Cr,Fe)7C3 as the reinforcing phase and interdendritic Fe+(Cr,Fe)7C3 eutectics as the matrix. The (Cr,Fe)7C3 carbide-reinforced claddings have high hardness and excellent wear resistance under abrasive wear test conditions. Concerning the abrasive wear feature observable on the worn surface, the formation and fraction of massive primary (Cr,Fe)7C3 carbides predominates the wear resistance of hardfacing alloys. Abrasive particles result in continuous plastic grooves when the cladding has primary γ-Fe phase in a hypoeutectic structure.

Effect of gelatin nano-coating containing Gardenia pigment on the preservation of pork slices
Yong Liu,Zi-Hao Liu,Chang-Qi Luo,Chun-Tao Xiao,Wen-Yu Zhou,Wen-Jin Xie 한국식품과학회 2022 Food Science and Biotechnology Vol.31 No.4
The nano-coating composed of gelatin and Gardenia pigment (GP) was successfully prepared and showed strong antioxidant activity. The average particle sizes of the nano-coating containing 0.1% and 0.3% GP were 269.58 and 394.13 nm, respectively. The pork slices uncoated and coated with the nano-coating were preserved at 4 C for 15 days. The pork slices’ pH, total volatile basic nitrogen (TVB-N), total viable counts (TVC), water-bind- ing capacity (WHC), and thiobarbituric acid reactive sub- stances (TBARS) were measured to assess the preservation effect of the nano-coating. The results showed that the pork coated with the nano-coating had lower pH, TVC, TVB-N, TBARS, and higher WHC, significantly different (p \ 0.05) than the uncoated pork. It is suggested that the proposed nano-coating can be used to effectively improve the pork’s quality and shelf life during refrigeration storage.

( Hung-hsu Yen ),( Chun-hao Chang ) 세계문화관광학회 2014 International Journal of Culture and tourism Resea Vol.7 No.1
Cultural tourism is one of the most popular types of tourism nowadays; however, the mass tourism travel behavior can easily be seen in many cultural attractions. The main purposes of this study were to explore: 1) What are the tourists’ motivations while traveling in Anping area. 2) Would the tourists’ behavior in Anping area act with in-depth and learning behavior. 3) Exploring tourists’ perception differences in Anping area. 4) Exploring different tourists’behavior within different cultural involvement groups. This study applied the convenience sampling to collect 295 valid questionnaires. The results showed: 1) Tourists’ motivations in Anping area tended to like mass tourism motivations. 2) Most tourists’ information searching, visiting, and consuming behaviors in Anping area acted like mass tourism travel type. 3) Anping area’s main cultural concept could not be properly delivered to the tourists. 4) Information searching, tourist guide, and cultural related products consuming were less used by high involvement cultural tourists. This study suggested the government should enhance the cultural elements, the historic story, the design of cultural related products and the planning of whole environment. Moreover, the improvement of self-guide system, the training of commentator, and the promotion of the usage of guiding system were still need to be done. Finally, this study suggested the Tourism Bureau should develop a guiding book to encourage and guide the tourists how to enjoy/explore the true culture of each attractions. Moreover, the proper behavior and perception in cultural attractions should also be educated in future education system or promotion activities. To let tourists know the proper perception, behavior, manner and rules in cultural tourism will enhance the future development of cultural tourism in Taiwan.Keywords:Tourism Motivation, Tourism Behavior, Cultural Tourism Perception.

To meet future demands for cutting-edge wearable electronics, flexible supercapacitors must possess many features, such as eco-friendly processing, aesthetic appeal and no health hazards, in addition to have lightweight, robust and excellent cycling stability. We proposed a biomimetic and scalable method to fabricate an all-solid-state flexible supercapacitor (assFSC) using bioinspired clay/polymer nanocomposites as electrode materials and a gel electrolyte. Experimental results from X-ray techniques (tomography, scattering and diffraction) showed that the electrode’s structure features a 3D ant-nest-like framework composed of 2D nacre-like clay nanosheets, i.e. hierarchical layers-within-networks structure. Accordingly, the structural electrodes exhibit high tensile strength of 62 MPa, Young’s modulus of 4.4 GPa, and torsional strength of 165 MPa. Under a large operating potential of 4.0 V, the assFSC exhibited ultrahigh energy density (233.3 W h kg<SUP>-1</SUP> at 2 kW kg<SUP>-1</SUP>), ultrahigh power density (125 kW kg<SUP>-1</SUP> at 55.5 W h kg<SUP>-1</SUP>), and outstanding static cyclability (less than 10% loss after 5,000 cycles). We also performed a cycle-life test under dynamic deformation and demonstrated that the assFSC had charging and discharging abilities during motion, according to particle applications of wearable electronics. Thus stable and superior electrochemical performance can be attributed to the biomimetic layers-within-networks structure, which not only provided robust framework but also induced 3D conducting networks with increasing ion channels and shortening charge transports. The shapeable electrodes made by a molding process could, therefore, be used to meet the demands for fashionable, wearable electronics.

Background: The objective of this study was to investigate antioxidant and anti-inflammatory activity of cabbage phytochemicals. Materials and Methods: Color coordinates were evaluated by colorimetry, and the antioxidant and anti-inflammatory activities were analyzed by spectrophotometer for some common cabbage varieties. Results: Red heads had the highest total antioxidant contents followed by Savoy, Chinese and green heads. The Chinese variety had the highest ABTS (2,2-azino-di-(3-ethylbenzthiazoline-sulfonic acid) antioxidant activity, was 5.72 ${\mu}mol$ TE/g fw (Trolox equivalent). The green variety had the highest DPPH (free radical scavenging activity) antioxidant activity, which was 91.2 ${\mu}mol$ TE/g fw. The red variety had the highest FRAP (ferric reducing antioxidant power) antioxidant activity, which was 80.8 ${\mu}mol$ TE/g fw. The total phenol amounts were 17.2-32.6 mM trolox equivalent antioxidant capacity (TEAC) and the total flavonoid amounts were 40.0-74.2 mg quercetin per gram. Methanolic extracts of different cabbage heads showed different anti-inflammatory activity values. Chinese, Savoy and green heads had the highest anti-inflammatory activity, while red heads had the lowest. Conclusions: The results suggest that these varieties of cabbage heads could contribute as sources of important antioxidant and anti-inflammatory related to the prevention of chronic diseases associated to oxidative stress, such as in cancer and coronary artery disease.

Eosinophilia in Pleural Effusions: a Speculative Negative Predictor for Malignancy
Chu, Fang-Yeh,Liou, Ching-Biau,Sun, Jen-Tang,Bei, Chia-Hao,Liou, Tse-Hsuan,Tan, N-Chi,Yu, Yun-Chieh,Chang, Chih-Chun,Yen, Tzung-Hai,Su, Ming-Jang Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.3
Background: Eosinophilic pleural effusion (EPE) is an eosinophil count more than 10% on cytology of pleural samples. Recently, it was reported that malignancy had been the most prevalent cause inducing EPE. Therefore, we conducted an analysis on the prevalence and etiology of EPE and investigated the relationship between EPE and malignancy. Materials and Methods: Data for pleural cell differential count from patients receiving thoracentesis during the period from January 2008 to December 2013 were compared with clinical data and established diagnosis of patients obtained via electronic chart review. Results: A total of 6,801 requests of pleural cytology from 3,942 patients with pleural effusion who had received thoracentesis were available at Far Eastern Memorial Hospital from 2008 to 2013, and of these subjects, 115 (2.9%) were found to have EPE. The most frequent cause of EPE was malignancy (33.0%, n=38), followed by parapneumonic effusions (27.8%, n=32), tuberculosis pleuritis (13.9%, n=16), transudate effusions (12.2%, n=14) and the presence of blood or air in pleural space (10.4%, n=12). Additionally, an inverse relationship of eosinophilia in pleural fluid was identified in patients with malignancy and EPE. The cut-off eosinophil count in pleural fluid was 15% for the most accurate discrimination between malignancy and benign disorders in patients with EPE. At the cut-off level, the sensitivity and specificity were 65.8% and 67.5%, respectively. Conclusions: Pleural fluid eosinophilia was a speculative negative predictor for malignancy, despite the fact that cancers, including lung cancers and metastatic cancers to lung, were the most leading cause of pleural fluid eosinophilia. An inverse correlation was observed between the pleural eosinophil percentage and the likelihood of malignancy in patients with EPE.
