MiR-106b promotes cell proliferation via targeting RB in laryngeal carcinoma
MiR-106b is frequently up-regulated in various types of human cancer including laryngeal carcinoma. However the underlying mechanism of miR-106b involved in laryngeal carcinoma remains elusive. Here we showed that reduction of miR-106b induced cell cycle G0/G1 arrest by targeting tumor suppressor RB in human laryngeal carcinoma cells. Further, Introducing RB cDNA without 3'UTR abrogated miR-106b-induced cell proliferation. Finally, there was an inverse relationship between RB and miR-106b expression in laryngeal carcinoma tissues. To our knowledge, these data indicate for the first time that miR-106b directly regulate cell cycle by targeting RB in laryngeal carcinoma and that miR-106b could be potential therapeutic approaches for laryngeal carcinoma

Biosensing Technologies for Mycobacterium tuberculosis Detection: Status and New Developments
Biosensing technologies promise to improve Mycobacterium tuberculosis (M. tuberculosis) detection and management in clinical diagnosis, food analysis, bioprocess, and environmental monitoring. A variety of portable, rapid, and sensitive biosensors with immediate “on-the-spot” interpretation have been developed for M. tuberculosis detection based on different biological elements recognition systems and basic signal transducer principles. Here, we present a synopsis of current developments of biosensing technologies for M. tuberculosis detection, which are classified on the basis of basic signal transducer principles, including piezoelectric quartz crystal biosensors, electrochemical biosensors, and magnetoelastic biosensors. Special attention is paid to the methods for improving the framework and analytical parameters of the biosensors, including sensitivity and analysis time as well as automation of analysis procedures. Challenges and perspectives of biosensing technologies development for M. tuberculosis detection are also discussed in the final part of this paper
Increased plasma renin by vasodilators promotes the progression of abdominal aortic aneurysm
Background: It is well-accepted that antihypertensive therapy is the cornerstone of treatment for abdominal aortic aneurysm (AAA) patients with hypertension. Direct-acting vasodilators were used in the treatment of hypertension by directly relaxing vascular smooth muscle but may have destructive effects on the aortic wall by activating the renin–angiotensin system axis. Their roles in AAA disease remain to be elucidated. In this study, we used hydralazine and minoxidil, two classical direct-acting vasodilators, to investigate their influence and potential mechanisms on AAA disease.Methods and results: In this study, we investigated the plasma renin level and plasma renin activity in AAA patients. Simultaneously, age and gender ratio-matched patients diagnosed with peripheral artery disease and varicose veins were selected as the control group using a ratio of 1:1:1. Our regression analysis suggested both the plasma renin level and plasma renin activity are positively associated with AAA development. In view of the well-established relationship between direct-acting vasodilators and increased plasma renin concentration, we established a porcine pancreatic elastase-infused AAA mouse model, followed by oral administration of hydralazine (250 mg/L) and minoxidil (120 mg/L) to investigate effects of direct-acting vasodilators on AAA disease. Our results suggested both hydralazine and minoxidil promoted the progression of AAA with increased aortic degeneration. Mechanistically, the vasodilators aggravated aortic inflammation by increased leukocyte infiltration and inflammatory cytokine secretion.Conclusion and relevance: The plasma renin level and plasma renin activity are positively associated with AAA development. Direct vasodilators aggravated experimental AAA progression, which raised cautionary concerns about their applications in AAA disease
A Multistep Extending Truncation Method towards Model Construction of Infinite-State Markov Chains
The model checking of Infinite-State Continuous Time Markov Chains will inevitably encounter the state explosion problem when constructing the CTMCs model; our method is to get a truncated model of the infinite one; to get a sufficient truncated model to meet the model checking of Continuous Stochastic Logic based system properties, we propose a multistep extending advanced truncation method towards model construction of CTMCs and implement it in the INFAMY model checker; the experiment results show that our method is effective
Fluorescent Nanoparticle-Based Indirect Immunofluorescence Microscopy for Detection of Mycobacterium tuberculosis
A method of fluorescent nanoparticle-based indirect immunofluorescence microscopy
(FNP-IIFM) was developed for the rapid detection of Mycobacterium tuberculosis.
An anti-Mycobacterium tuberculosis antibody was used as primary antibody to recognize
Mycobacterium tuberculosis, and then an antibody binding protein (Protein A) labeled with
Tris(2,2-bipyridyl)dichlororuthenium(II) hexahydrate (RuBpy)-doped silica nanoparticles was
used to generate fluorescent signal for microscopic examination. Prior to the detection, Protein A was immobilized on RuBpy-doped silica nanoparticles with a coverage of ∼5.1×102 molecules/nanoparticle. With this method, Mycobacterium tuberculosis in bacterial mixture as
well as in spiked sputum was detected. The use of the fluorescent nanoparticles reveals amplified
signal intensity and higher photostability than the direct use of conventional fluorescent dye as
label. Our preliminary studies have demonstrated the potential application of the FNP-IIFM
method for rapid detection of Mycobacterium tuberculosis in clinical samples
Clinical application of CT-guided 125I seed interstitial implantation for local recurrent rectal carcinoma
<p>Abstract</p> <p>Purpose</p> <p>The present study aimed to explore the safety profile and clinical efficacy of CT-guided radioactive seed implantation in treating local recurrent rectal carcinoma.</p> <p>Materials and methods</p> <p>CT-guided <sup>125</sup>I seed implantation was carried out in 20 patients with locally recurrent rectal carcinoma. 14 of the 20 patient had prior adjuvant external-beam radiation therapy (EBRT). The treatment planning system (TPS) was used preoperatively to reconstruct three dimensional images of the tumor and to calculate the estimated seed number and distribution. The median matched peripheral dose (MPD) was 120 Gy (range, 100-160 Gy).</p> <p>Results</p> <p>Of the 20 patients, 12 were male, 8 were female, and ages ranged from 38 to 78, with a median age of 62. Duration of follow-up was 3-34 months. The response rate of pain relief was 85% (17/20). Repeat CT scan 2 months following the procedure revealed complete response (CR) of the tumor in 2 patients, partial response (PR) in 13 patients, stable disease (SD) in 3 patients, and progressive disease (PD) in 2 patients. 75% of patients had either CR or PR. Median survival time was 18.8 months (95% CI: 3.5-22.4 months). 1 and 2 year survival rates were 75% and 25%, respectively. 4 patients died of recurrent tumor; 4 patients died of distant metastases; 9 patients died of recurrent tumor and distant metastases. 3 patients survived after 2 year follow up. Two patients were found to have mild hematochezia, which was reversible with symptomatic management.</p> <p>Conclusion</p> <p>CT-guided <sup>125</sup>I seed implantation appeared to be a safe, useful and less complicated interventional treatment option for local recurrent rectal carcinoma.</p
