Prevalence of Hematuria among Emergency Department Healthcare Workers  [PDF]
Ho-Hsing Lin, Chi-Wen Juan, Li-Ya Lin, Chi-Wei Lee, Chien-Jen Huang
International Journal of Clinical Medicine (IJCM) , 2014, DOI: 10.4236/ijcm.2014.519154
Abstract: Background: In Taiwan, emergency departments are so busy that it is not uncommon for staffs (doctors and nurses) to be deprived of their lunch breaks or breaks to go to the restroom. As a consequence, during their busy shifts some emergency department healthcare workers choose to limit their water intake and no time to micturate which are both risk factors of urinary tract infection or urolithiasis. Hematuria is a common laboratory finding due to urinary tract infection and urolithiasis. Objective: To assess the prevalence of hematuria among the emergency department healthcare workers, we conducted a retrospective study in a district hospital in Taiwan. Documented data included those of healthcare workers who worked in the emergency department, as well as other departments of the same hospital. Methods: We reviewed the three-year records of general body checkup of hospital staffs who served in the emergency room and other departments of the same hospital between January 1, 2009 and December 31, 2011. Statistical software SPSS statistical analysis of survey data recovery is applied; data and test results by the questionnaire analysis patterns are associated with the urinary system abnormalities to ANOVA analysis to explore the hospital group whether there is a significant sex differences, and the other to analyze and verify the correlation analysis to the Scheffe post-hoc comparison method. Results: A higher prevalence of hematuria was observed among emergency department healthcare workers when compared with their colleagues who work in other departments of the same hospital. Female workers have higher risk of urinary system abnormalities than male workers. Nurses in the urinary system abnormalities are higher than other positions category. Shift work system has a negative effect on the urinary system. Conclusion: In conclusion, hematuria is more prevalent among emergency department healthcare workers than healthcare workers working in the inpatient wards. Hematuria might well be due to urinary tract infection which in turns caused by the overwhelmingly busy nature of the emergency department duty that deprived the emergency department healthcare workers from frequent voiding and sufficient intake of fluid.
Two-dimensional electron gas in uniform magnetic and electric fields
Choon-Lin Ho,V. R. Khalilov,Chi Yang
Physics , 1996,
Abstract: The thermodynamic potential of an ideal nonrelativistic gas of two-dimensional electrons in crossed uniform magnetic and electric fields is constructed. For low temperatures and very weak electric fields, it is shown that the Hall conductance is always quantized at integral multiples of $e^2/h$ over a large range of strong magnetic fields. This could be viewed as a quantum statistical explanation of the integral quantum Hall effect. Magnetic properties of the system at high temperatures are briefly discussed.
Effect of Strong Magnetic Fields on the Equilibrium of a Degenerate Gas of Nucleons and Electrons
Choon-Lin Ho,V. R. Kahlilov,Chi Yang
Physics , 1996, DOI: 10.1142/S0217984996001309
Abstract: We obtain the equations that define the equilibrium of a homogeneous relativistic gas of neutrons, protons and electrons in a constant magnetic field as applied to the conditions that probably occur near the center of neutron stars. We compute the relative densities of the particles at equilibrium and the Fermi momentum of electrons in the strong magnetic field as function of the density of neutrons and the magnetic field induction. Novel features are revealed as to the ratio of the number of protons to the number of neutrons at equilibrium in the presence of large magnetic fields.
Multi-indexed Extensions of Soliton Potential and Extended Integer Solitons of KdV Equation
Choon-Lin Ho,Jen-Chi Lee
Physics , 2014,
Abstract: We calculate infinite set of initial profiles of higher integer KdV solitons, which are both exactly solvable for the Schrodinger equation and for the Gel'fand-Levitan-Marchenko equation in the inverse scattering transform method of KdV equation. The calculation of these higher integer soliton solutions is based on the recently developed multi-indexed extensions of the reflectionless soliton potential.
The Effects of Social Interaction and Psychological Bias on Trading Behavior: Evidence from a Laboratory Experiment  [PDF]
Chi Ming Ho
Journal of Mathematical Finance (JMF) , 2018, DOI: 10.4236/jmf.2018.81014
Abstract: This paper details an experiment designed to explore the trading behaviors of investors that result from psychological biases and social interactions. In total, 88 investors were tracked for 6 months and 40,795 transactions were recorded. The research conducted an experimental survey and estimated a system analysis model to generate several important conclusions. First, the degree of regret bias and the disposition effects are unrelated, probably because the professional training of investors and the disposition effects are not significantly related. Second, if investors are affected by contradictions arising from their decisions, then the likelihood that they will sell a stock will decrease as the investor relationships in the community improve and the regret bias increases. Third, male investors prefer to trade derivatives, and even after controlling for the degree of regret bias, this preference is still significant.
Ecto-Nucleoside Triphosphate Diphosphohydrolase 2 Modulates Local ATP-Induced Calcium Signaling in Human HaCaT Keratinocytes
Chia-Lin Ho, Chih-Yung Yang, Wen-Jie Lin, Chi-Hung Lin
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0057666
Abstract: Keratinocytes are the major building blocks of the human epidermis. In many physiological and pathophysiological conditions, keratinocytes release adenosine triphosphate (ATP) as an autocrine/paracrine mediator that regulates cell proliferation, differentiation, and migration. ATP receptors have been identified in various epidermal cell types; therefore, extracellular ATP homeostasis likely determines its long-term, trophic effects on skin health. We investigated the possibility that human keratinocytes express surface-located enzymes that modulate ATP concentration, as well as the corresponding receptor activation, in the pericellular microenvironment. We observed that the human keratinocyte cell line HaCaT released ATP and hydrolyzed extracellular ATP. Interestingly, ATP hydrolysis resulted in adenosine diphosphate (ADP) accumulation in the extracellular space. Pharmacological inhibition by ARL 67156 or gene silencing of the endogenous ecto-nucleoside triphosphate diphosphohydrolase (NTPDase) isoform 2 resulted in a 25% reduction in both ATP hydrolysis and ADP formation. Using intracellular calcium as a reporter, we found that although NTPDase2 hydrolyzed ATP and generated sustainable ADP levels, only ATP contributed to increased intracellular calcium via P2Y2 receptor activation. Furthermore, knocking down NTPDase2 potentiated the nanomolar ATP-induced intracellular calcium increase, suggesting that NTPDase2 globally attenuates nucleotide concentration in the pericellular microenvironment as well as locally shields receptors in the vicinity from being activated by extracellular ATP. Our findings reveal an important role of human keratinocyte NTPDase2 in modulating nucleotide signaling in the extracellular milieu of human epidermis.

Abstract:

Seizures can lead to different injuries ranging from minor lacerations to serious head injuries or bony fractures. We report a rare case of a male patient presenting with a history of a distended abdomen and gross hematuria following a seizure attack. After catheterization, the drained urine was bloodstained. On clinical suspicion of an acute abdomen, computed tomography was conducted, which showed intraperitoneal rupture of the bladder. At laparotomy, we found and repaired a laceration in the dome of the bladder in 3 layers. The postoperative period was uneventful. Our case shows that a complete abdominal examination is needed on patients following a generalized seizure episode. We also suggest that certain drugs for treating schizophrenia have anticholinergic effects, which may induce chronic urine retention. Chronic urine retention, especially in elderly male patients, may contribute to the risk of a spontaneous rupture of the bladder.

Research on the allelopathic potential of wheat  [PDF]
Yau Lam, Cho Wing Sze, Yao Tong, Tzi Bun Ng, Sydney Chi Wai Tang, James Chung Man Ho, Qiaoqing Xiang, Xiao Lin, Yanbo Zhang
Agricultural Sciences (AS) , 2012, DOI: 10.4236/as.2012.38119
Abstract: Objective: This paper mainly discusses the Allelopathic potential of Wheat. Methods: This paper is prepared by reviewing the latest academic literatures. Result: The green revolution in the 1960s caused an increase in the demand for food. The agricultural sector and farmers tended to spend more time on the agricultural work but the crop yield was suppressed by the weeds. Hence, the usage of herbicide insecticides, fungicides and others chemicals had been increased. Although herbicides are efficient for weed controls, the continuous uses had gradually stimulated the weeds developing an effecttive resistance to the chemicals. Wheat (Triticum aestivum L.) is known as allelopathic against crops and weeds. Allelopathy of wheat (Triticum aestivum L.) has been extensively examined for its potentials in weeds management. The allelopathic activity of wheat has been attributed to hydroxamic acids, the related compounds and phenolic acids. Therefore, it could effectively reduce herbicide uses in order to maintain an eco-friendly environment and a cost-effective weed control.

Analytical and Experimental Study of Recycling Baffled Double-Pass Solar Air Heaters with Attached Fins
Chii Dong Ho,Hsuan Chang,Rei Chi Wang,Chun Sheng Lin
Energies , 2013, DOI: 10.3390/en6041821
Abstract: The study of the heat transfer of solar air heaters with a new design using an absorbing plate with fins and baffles, which facilitate the recycling of flowing air, is reported. The mathematical formulation and analytical analysis for such a recyclic baffled double-pass solar air heater were developed theoretically. The performance of the device was studied experimentally as well. The theoretical predicted and experimental results were compared with another design, i.e., a downward-type single-pass solar air heater without recycle and double-pass operations reported in our previous work. Significant improvement in heat-transfer efficiency is achieved with the baffle and fin design due to the recycling heating and the extended heat transfer area. The effects of mass flow rate and recycle ratio on the heat-transfer efficiency enhancement as well as on the power consumption increment are also discussed.
