AIMS We aimed to obtain pyloric measurements of our patients with infantile hypertrophic pyloric stenosis (IHPS) using ultrasonography (US) and to evaluate the correlations between age, weight and pyloric size, pyloric ratio (PR). MATERIAL AND METHODS We designed a retrospective study including 20 term infants with surgically proven IHPS and studied the ultrasonographically obtained pyloric m...

OBJECTIVE We applied a modified pharmacomechanical thrombolysis (PMT) technique to endovascular treatment of thrombosed arteriovenous (AV) grafts without the use of any mechanical thrombectomy devices. The aim of this study was to evaluate the efficacy of the PMT technique in the treatment of thrombosed AV grafts by analyzing the long-term patency. MATERIALS AND METHODS Eighty-two patients wi...

Malignant pleural mesothelioma (MPM) is a lethal disease with poor prognosis. The combination of cisplatin and pemetrexed has been confirmed as the standard of care for nonoperable MPM. Data have shown that the adoption of pemetrexed maintenance therapy (PMT) following first-line treatment appears extremely promising.We describe a 57-year-old man diagnosed as advanced MPM. We treated this patie...

In order to develop a long-lifetime MCP-PMT under high rates of circumstance, we investigated the degradation of the quantum efficiency (QE) of PMT’s with a multialkali photocathode. We found that not only positive ions, but also neutral residual gases would damage the photocathode resulting in an enhancement of the work function; their countermeasures were established in newly manufactured squ...

To examine the lifetime of a micro-channel plate photo-multiplier tube, we measured its basic performance, gain, quantum efficiency (QE), transit time spread and dark counts as a function of the integrated amount of irradiated photons up to 2:8 10 photons=cm, corresponding to a 14-year time duration under supposed super-KEKB experimental conditions. The effect of the ion-feedback protection lay...

At Drexel University, I was testing the 8-inch, 13 stages, R1408 PMTs which will be used for the inner vetos of the Double Chooz experiment [1]. These PMTs were used in the IMB [2] and SuperKamiokande [3] experiments. This testing allowed a better understanding of their working. In this paper I propose a model inspired from observations during the testing period. The first aim of this model is ...

The sensitivity of a possible future 1 Megaton water Cherenkov detector for proton decay searches was studied. For p e π0 decay mode, the detection efficiency and the number of atmospheric neutrino backgrounds were estimated by using a detailed Monte Carlo simulation program. Moreover, their dependence on the number density of the photomultiplier tube (PMT) was investigated. With the PMT densit...

Pseudomembranous tracheitis (PMT) is a rare condition most commonly caused by fungal or bacterial infection that is characterized by a pseudomembrane that partially or completely covers the tracheobronchial tree. PMT is most commonly found in immunocompromised patient populations, such as post-chemotherapy, AIDS, post-transplant and hematological malignancies. Due to its rarity, PMT is often no...

6to4 Provider Managed Tunnels (6to4-PMT) provide a framework that can help manage 6to4 tunnels operating in an anycast configuration. The 6to4-PMT framework is intended to serve as an option for operators to help improve the experience of 6to4 operation when conditions of the network may provide sub-optimal performance or break normal 6to4 operation. 6to4-PMT supplies a stable provider prefix a...

Pasteurella multocida produces a 146-kDa protein toxin (Pasteurella multocida toxin, PMT), which stimulates diverse cellular signal transduction pathways by activating heterotrimeric G proteins. PMT deamidates a conserved glutamine residue of the α-subunit of heterotrimeric G proteins that is essential for GTP-hydrolysis, thereby arresting the G protein in the active state. The toxin substrates...
