MicroRNAs (miRNAs) are involved in tumorigenecity by regulating specific oncogenes and tumor suppressor genes, and their roles in breast cancer stem cells (BCSCs) are becoming apparent. Distinct from the CD44 /CD24 /low sub-population, we have isolated a novel PROCR /ESA BCSC sub-population. To explore miRNA-regulatory mechanisms in this sub-population, we performed miRNA expression profiling and found miR-495 as the most highly upegulated miRNA in PROCR /ESA cells. Coincidently, high upregulation of miR-495 was also found in CD44+ /CD24 /low BCSCs, reflecting its potential importance in maintaining common BCSC properties. Ectopic expression of miR-495 in breast cancer cells promoted their colony formation in vitro and tumorigenesis in mice. miR-495 directly suppressed E-cadherin expression to promote cell invasion and inhibited REDD1 expression to enhance cell proliferation in hypoxia through post-transcriptional mechanism. miR-495 expression was directly modulated by transcription factor E12/E47, which itself is highly expressed in BCSCs. These findings reveal a novel regulatory pathway centered on miR-495 that contributes to BCSC properties and hypoxia resistance. © 2011 Macmillan Publishers Limited All rights reserved.

Two microbial fuel cells with different oxygen supplies in the cathodic chamber were constructed. Electrogenic capabilities of both cells were compared under the same operational conditions. Results showed that binary quadratic equations can express the relationships between chemical oxygen demand degradation rate and chemical oxygen demand loading and between chemical oxygen demand removal rate and chemical oxygen demand loading in both cells. Good linear relationships between power output (voltage or power density) and flow rate and between power output and chemical oxygen demand degradation rate were only found on the cell with mechanical aeration in the cathodic chamber, but not on the cell with algal photosynthesis in the cathodic chamber. The relationships between power output and chemical oxygen demand removal rate and between power output and effluent chemical oxygen demand concentration on both cells can be expressed as binary quadratic equations. The optimum flow rates to obtain higher power density and higher Coulombic efficiency in the cell with mechanical aeration in the cathodic chamber (=0.85 mW/m 2 and 0.063%) and in the cell with algal photosynthesis in the cathodic chamber (=0.65 mW/m 2 and 0.05%) are about 1000 and 1460 μL/min, respectively. The optimum chemical oxygen demand removal rates to obtain higher power density and higher Coulombic efficiency in the cell with mechanical aeration in the cathodic chamber (=1.2 mW/m 2 and 0.064%) and in the cell with algal photosynthesis in the cathodic chamber (=0.81 mW/m 2 and 0.051%) are about 40.5 and 36.5%, respectively. © 2012 CEERS, IAU.

BACKGROUND: Refinements in microsurgery have made distal finger replantation an established technique with high success rates and good functional and aesthetic outcomes. However, it still represents a technically demanding procedure due to the small vessel caliber and frequent lack of vessel length, requiring the use of interpositional venous grafts in some instances. We describe a new technique for anastomosis in fingertip replantation, whereby the need for venous grafts is eliminated. METHODS: Applying the reverse distal transverse palmar arch technique, 11 cases of distal digital replantation were performed between January 2011 and July 2016. The described procedure was used for arterial anastomosis in 10 cases and arteriovenous shunting for venous drainage in 1 case. A retrospective case review was conducted. The technical description and clinical outcome evaluations are presented. RESULTS: Ten of the 11 replanted digits survived, corresponding to an overall success rate of 91%. One replant failed due to venous insufficiency. Blood transfusions were not required for any of the patients. Follow-up (range, 1.5–5 months) revealed near-normal range of motion and good aesthetic results. All of the replanted digits developed protective sensation. The average length of hospital admission was 5 days. All patients were satisfied with the results and were able to return to their previous work. CONCLUSIONS: The use of the reverse distal transverse palmar arch is a novel and reliable technique in distal digital replantation when an increase in vessel length is required, allowing for a tension-free arterial repair without the need for vein grafts.

OBJECTIVE: Gastrointestinal bleeding scintigraphy (GIBS) offers the advantage of continuous monitoring of patients to localize the site of gastrointestinal bleeding. In this study, a modified in vivo labeling method with sedimentation of the labeled red blood cells (RBC) was applied to remove free technetium-99m (99mTc) and increase labeling efficiency.PATIENTS AND METHODS: Four patients were studied. A modified in vivo RBC labeling method was used. After 10 minutes of RBC sedimentation, patients' blood plasma in the upper part of the syringe was removed, and the erythrocytes labeled with 99mTc were re-administered to the patient. Serial dynamic scintiphotos were taken during the first 60 minutes. Delayed static images were acquired up to 22 hours after injection.RESULTS: The labeling efficiency of 99mTc-RBC increased up to 93%. GIBS can be performed after 20 hours post-injection and provide accurate diagnosis of gastrointestinal bleeding. No false positive findings due to free 99mTc accumulation were observed for the four patients.CONCLUSION: The modified in vivo method with sedimentation is a simple and effective way to increase the labeling efficiency and thus the diagnosis for the detection of gastrointestinal bleeding.

Objectives: To explore the magnitude of nonemergent emergency department visits under the Taiwan National Health Insurance program and to identify significant factors associated with these visits. Methods: A cross-sectional analysis of the 2002 Taiwan National Health Insurance Research Database was used to identify nonemergent emergency department conditions according to the New York University algorithm. The data contained 43,384 visits, of which 83.89% could be classified. Multivariate logistic regression identified individual and contextual factors associated with nonemergent emergency department visits. Results: Nearly 15% of all emergency department visits were nonemergent; an additional 20% were emergent-preventable with primary care. Patients likely to make nonemergent emergency department visits were older, female, categorized as a Taiwan National Health Insurance Category IV beneficiary, and without major illness. Hospital accreditation level, teaching status, and location were associated with an increased likelihood of nonemergent emergency department visits. Conclusion: Understanding the factors leading to nonemergent emergency department visits can assist in evaluating the overall quality of a health care system and help reduce the use of the emergency department for nonemergent conditions. Policy makers desiring cost-effective care should assess emergency department visit rates in light of available resources for specific populations. © 2010 Elsevier Ireland Ltd.

Four microbial fuel cells (MFCs) inoculated with different bacterial species were constructed. The species were Pseudomonas putida, Comamonas testosteroni, Corynebacterium gultamicum, and Arthrobacter polychromogenes. The MFCs were operated under identical continuous flow conditions. The factors affecting the capabilities of the MFCs for treating organic matter and generating power were evaluated and compared. The factors include microbial species type, organic loading, and substrate degradation rate. For all four MFCs, power output increased with the organic loading rate. Power density also increased with the substrate degradation rate. These findings implied that more organic matter was utilized for power generation at higher organic loading and substrate degradation rates. However, coulombic efficiency increased with decreased organic loading and substrate degradation rates. Apparently, all four MFCs had low efficiencies in generating power from organic matter. These low efficiencies are attributed to the long distance between the anode and the cathode, as well as to the small ratio of the proton exchange membrane surface area to the anode chamber surface area. These features may have caused most of the protons produced in the anode chamber to leave the chamber with the effluent, which led to the low power generation performance of the MFCs. © 2011 Springer Science+Business Media B.V.

In this study, time-domain cross-correlation function was applied to evaluate the relationship between blood pressure and cerebral blood flow velocity signals acquiring from healthy subjects and stroke patients both in supine and head-up tilt positions to evaluate the effect of posture change. 10 stroke patients and 11 healthy subjects were included in this study. Results revealed that the mean arterial blood pressure (MABP) values of stroke patients in response to posture changes were reduced. However, MABP values in healthy subjects were become higher in head-up tilt position. Both of MABP values of healthy subjects in supine and head-up tilt were significantly lower than those in stroke patients (p<0.05). On the other hand, mean cerebral blood flow velocity (MCBFV) in healthy subjects remain constant. However, the values in stroke patients reduced in response to headup tilt. In the results of cross-correlation function (CCF) analysis, max CCF values in healthy subjects were significantly higher than those in stroke patients (p<0.05) in both supine and head-up tile positions. It might indicate correlation of MABP and MCBFV was higher in healthy subjects. The max CCF index in stroke patients were close to 0 second in both positions (supine: - 0.35±3.36 sec; head-up tilt:-0.29±3.20 sec). In healthy subjects, max CCF values should be around 2 seconds. Hence, it indicated the phase difference almost did not exist between MABP and MCBFV. This reveals the buffer function of CA were lower in stroke patients. Therefore, CA in stroke patients might be impaired by the results in response to posture changes.

Negative pressure pulmonary edema (NPPE) or postobstructive pulmonary edema (POPE) is a form of noncardiogenic pulmonary edema that results from the generation of high negative intrathoracic pressure needed to overcome upper airway obstruction 1. It typically develops rapidly and can be life-threatening if not diagnosed promptly. Following an episode of acute airway obstruction or the relief of chronic upper airway obstruction, patients with NPPE develop sudden, unexpected and often severe pulmonary edema. Awareness of this uncommon condition is crucial if the physician is to make an early diagnosis and initiate successful treatment. NPPV may develop in several clinical situations follows a sudden, severe episode of upper airway obstruction, such as postanesthetic laryngospasm, postextubation laryngospasm, epiglottitis, croup, choking and strangulation. It also develops after surgical relief of chronic upper airway obstruction.

Molecular diagnostic tests have greatly increased our understanding of the role of viruses in pneumonia, and findings indicate that the incidence of viral pneumonia has been underestimated. The most commonly identified viruses in community-acquired pneumonia (CAP) are influenza, rhinovirus, respiratory syncytial virus (RSV), and human metapneumovirus (hMPV). Viral infections are common in adults with CAP, ranging from 10-30% of diagnosed cases. Polymicrobial infections involving bacterial and viral pathogens are frequent and may be associated with severe pneumonia. Besides, cytomegalovirus, herpes simplex and herpes zoster virus may cause severe respiratory illness and life-threatening pneumonia in immunocomromised adults (neoplasm, organ-transplantation, acquired immunodeficiency syndrome, AIDS).
