Yu, Chi-Yuang,Hsu, Yau-Wen,Chung, Yi-Chan,Tsai, Chih-Hung The Korean Society for Quality Management 2004 The Asian Journal on Quality Vol.5 No.2
The purpose of this study was to analyze the prevalence of self-reported musculoskeletal symptoms among the three Taiwan's traditional industries as lathe, electronics and food by the Nordic Musculoskeletal Questionnaire (NMQ). Moreover, the study was also to make a comparison among the aforesaid industries for revealing their differences. The result of the questionnaire indicated that the symptoms appeared on the three industries were all originated from four parts as neck, shoulders, elbows, and wrists/hands. More than 68% of the interviewers thought that their symptoms might be related to their work. However, the rate of harmful influence resulted from life or job was over 50%. As to the respect of the interviewers' attitude in treating their symptoms, more than 80% of them neglected or just treated the symptoms by massaging or cold/hot compressing and resting. From the questionnaire, the proportion of symptoms discussed in each item indicated that the distribution, in perceiving symptom, of interviewers were not quite identical; however the Chi-square test discovered majority did not reach 0.05 levels, hence the difference among industries were not significant.

Hung, Yu-Shin,Chou, Wen-Chi,Chen, Tai-Di,Chen, Tse-Ching,Wang, Po-Nan,Chang, Hung,Hsu, Hung-Chih,Shen, Wen-Chi,Cheng, Wei-Hong,Chen, Jen-Shi Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.1
Background: Solid cancers with bone marrow metastases are rare but lethal. This study aimed to identify clinical factors predictive of survival in adult patients with solid cancers and bone marrow metastases. Methods: A total of 83 patients were enrolled consecutively between January 1, 2000 and December 31, 2012. Bone marrow metastases were confirmed by biopsies. Patient clinical features and laboratory data were analyzed for associations. Results: The median age of the patients was 54 years (range, 23-88 years), and 58% were male. The 3 most common primary tumor locations were the stomach (32 patients, 39%), prostate (16 patients, 19%), and lungs (12 patients, 15%). The median overall survival was 49 days (range, 3-1423 days). Patients with Eastern Cooperative Oncology Group performance status 1, cancers of prostate origin, platelet counts over 50,000/ml, and undergoing antitumor therapies had a significantly better prognosis in the multivariate analysis. The median survival times were 173 and 33 days for patients with 2-3 more favorable parameters (n=24) and those with 0-1 (n=69), respectively (hazard ratio 0.30; 95% CI 0.17-0.52, p<0.001). Conclusions: Solid cancers with bone marrow metastases are dismal and incurable diseases. Understanding prognostic factors to these diseases helps medical personnel to provide appropriate treatments and better inform patients about outcomes. Antitumor therapies may improve outcomes in selected patient cohorts.

Background/Aims: Spontaneous bacterial peritonitis (SBP) contributes to poorer short-term mortality in cirrhotic patients with ascites. However, it is unknown how long the effect of the first SBP event persists in these patients. Methods: The National Health Insurance Database, derived from the Taiwan National Health Insurance Program, was used to identify and enroll 7,892 cirrhotic patients with ascites who were hospitalized between January 1 and December 31, 2007. All patients were free from episodes of SBP from 1996 to 2006. Results: The study included 1,176 patients with SBP. The overall 30-day, 90-day, 1-year, and 3-year mortality rates in this group were 21.8%, 38.9%, 57.5%, and 73.4%, respectively. The overall 30-day, 90-day, 1-year, and 3-year mortality rates in the non-SBP group were 15.7%, 32.5%, 53.3%, and 72.5%, respectively. After adjusting for gender, age, and other medical comorbidities, the adjusted hazard ratios of SBP for 30-day, 30- to 90-day, 90-day to 1-year, and 1- to 3-year mortality were 1.49 (95% confidence interval [CI], 1.30 to 1.71), 1.19 (95% CI, 1.02 to 1.38), 1.04 (95% CI, 0.90 to 1.20), and 0.90 (95% CI, 0.77 to 1.05), respectively, compared with the non-SBP group. Conclusions: The effect of SBP on the mortality of cirrhotic patients with ascites disappeared in those surviving more than 90 days after the first SBP event. (Gut Liver 2016;10:803-807)

The Phalaenopsis violacea complex includes two species: P. violacea Witte and Phalaenopsis bellina (Rchb.f.) E. A. Christ. However, three forms of P. violacea have been found in different areas, including Sumatra, the Malay Peninsula, and Mentawai Island. The phylogenetic tree inferred from the internal transcribed spacer (ITS)region of nuclear ribosomal DNA (nrDNA), the trnL intron,and the atpB-rbcL spacer of plastid DNA were used to clarify the phylogenetics and biogeography of the P. violacea complex. Analyses of the trnL intron sequences and of the atpB-rbcL spacer did not allow for apparent discrimination among these three species of the P. violacea complex. Based on the phylogenetic tree inferred from the ITS sequence, P. bellina cannot be separated from populations of P. violacea, with the exception of the population distributed on Mentawai Is., Indonesia. Based on morphological characteristics, P. violacea distributed on Mentawai Is. has a long and roundish rachis and is separate from the other groups of the P. violacea complex described by Christenson (Timber, Portland, OR, 2001). Therefore,the results of this study show a trend that supports the conclusion that the population of the P. violacea complex on Mentawai Is. is a separate species from P. violacea. Based on the biogeography of the P. violacea complex,Mentawai plants of this complex might be descended from those on the Sumatra/Malay Peninsula.

Background: Echocardiography is a primary tool used by veterinarians to evaluate heart diseases. In recent years, various studies have targeted standard echocardiographic values for different breeds. Reference data are currently lacking in Maltese dogs and it is important to fill this gap as this breed is predisposed to myxomatous mitral valve disease, which is a volume overload disease. Objectives: To establish the normal echocardiographic parameters for Maltese dogs. Methods: In total, 23 healthy Maltese dogs were involved in this study. Blood pressure measurements, thoracic radiography, and complete transthoracic echocardiography were performed. The effects of body weight, age and sex were evaluated, and the correlations between weight and linear and volumetric dimensions were calculated by regression analysis. Results: The mean vertebral heart size was 9.1 ± 0.4. Aside from the ejection fraction, fractional shortening, and the left atrial to aorta root ratio, all the other echocardiographic parameters were significantly correlated with weight. Conclusion: This study describes normal echocardiographic parameters that may be useful in the echocardiographic evaluation of Maltese dogs.
Concrete compressive strength identification by impact-echo method

A clear correlation exists between the compressive strength and elastic modulus of concrete. Unfortunately, determining the static elastic modulus requires destructive methods and determining the dynamic elastic modulus is greatly complicated by the shape and size of the specimens. This paper reports on a novel approach to the prediction of compressive strength in concrete cylinders using numerical calculations in conjunction with the impact-echo method. This non-destructive technique involves obtaining the speeds of P-waves and S-waves using correction factors through numerical calculation based on frequencies measured using the impact-echo method. This approach makes it possible to calculate the dynamic elastic modulus with relative ease, thereby enabling the prediction of compressive strength. Experiment results demonstrate the speed, convenience, and efficacy of the proposed method.

Inflammation alters the neural stem cell (NSC) lineage from neuronal to astrogliogenesis. However, the underlying mechanism is elusive. Autophagy contributes to the decline in adult hippocampal neurogenesis under E. coli lipopolysaccharide (LPS) stimulation. SRY-box transcription Factor 2 (SOX2) is critical for NSC self-renewal and proliferation. In this study, we investigated the role of SOX2 in induced autophagy and hippocampal adult neurogenesis under LPS stimulation. LPS (5 ng•100 g-1•hour-1 for 7 days) was intraperitoneally infused into male Sprague–Dawley rats (8 weeks old) to induce mild systemic inflammation. Beclin 1 and autophagy protein 12 (Atg12) were significantly upregulated concurrent with decreased numbers of Ki67- and doublecortin (DCX)-positive cells in the dentate gyrus. Synchronically, the levels of phospho(p)-mTOR, the p-mTOR/mTOR ratio, p-P85s6k, and the p-P85s6k/P85s6k ratio were suppressed. In contrast, SOX2 expression was increased. The fluorescence micrographs indicated that the colocalization of Beclin 1 and SOX2 was increased in the subgranular zone (SGZ) of the dentate gyrus. Moreover, increased S100β-positive astrocytes were colocalized with SOX2 in the SGZ. Intracerebroventricular infusion of 3-methyladenine (an autophagy inhibitor) effectively prevented the increases in Beclin 1, Atg12, and SOX2. The SOX2+-Beclin 1+ and SOX2+-S100β+ cells were reduced. The levels of p-mTOR and p-P85s6k were enhanced. Most importantly, the number of DCX-positive cells was preserved. Altogether, these data suggest that LPS induced autophagy to inactivate the mTOR/P85s6k pathway, resulting in a decline in neural differentiation. SOX2 was upregulated to facilitate the NSC lineage, while the autophagy milieu could switch the SOX2-induced NSC lineage from neurogenesis to astrogliogenesis.
