TY - JOUR. T1 - Urinary leukotriene E4 excretion during the first month of life and subsequent bronchopulmonary dysplasia in premature infants. AU - Sheikh, Shahid. AU - Null, Donald. AU - Gentile, Deborah. AU - Bimle, Colleen. AU - Skoner, David. AU - McCoy, Karen. AU - Guthrie, Robert. PY - 2001/1/1. Y1 - 2001/1/1. N2 - Background: Inflammation plays an important role in the pathogenesis of bronchopulmonary dysplasia (BPD), but the exact nature of this inflammatory process is incompletely understood. Older infants with established BPD have higher levels of urinary leukotriene E4 (LTE4) compared to healthy infants of the same age. This suggests that cysteinyl leukotrienes may play a role in the abnormalities seen in BPD. Objectives: To measure urinary LTE4 levels during the first month of life in premature infants, and to determine whether there are significant differences in premature infants who develop BPD, as compared to those who do not develop BPD. Design: Prospective, blinded, controlled ...

Background Anaphylaxis is a life-threatening syndrome resulting from the sudden release of mast cell- and basophil-derived mediators into the circulation. However, pathological evidence of the association between inflammatory mediators and human anaphylaxis is insufficient.. Objective The aim of this study was to better understand the relationship between in vivo production of inflammatory mediators and the pathogenesis of anaphylaxis. We also sought to evaluate mast cell activation in anaphylaxis.. Methods We measured the concentrations of various inflammatory mediators in urine samples, which were collected from 32 anaphylactic patients during the onset of anaphlaxis and during clinical remission, 21 patients with asthma on acute exacerbation and 15 healthy control subjects. Blood and urine specimens were collected from the patients after provocation test. Urinary leukotriene E4 (LTE4), 9α, 11β-prostaglandin F2 (9α, 11β-PGF2), eosinophil-derived neurotoxin (EDN) and leukotriene B4 ...
© 2015 American Academy of Allergy, Asthma & Immunology. Background Prostaglandin D 2 (PGD 2 ) and cysteinyl leukotrienes (cysLTs) are lipid mediators derived from mast cells, which activate T H 2 cells. The combination of PGD 2 and cysLTs (notably cysteinyl leukotriene E 4 [LTE 4 ]) enhances T H 2 cytokine production. However, the synergistic interaction of cysLTs with PGD 2 in promoting T H 2 cell activation is still poorly understood. The receptors for these mediators are drug targets in the treatment of allergic diseases, and hence understanding their interaction is likely to have clinical implications. Objective We aimed to comprehensively define the roles of PGD 2 , LTE 4 , and their combination in activating human T H 2 cells and how such activation might allow the T H 2 cells to engage downstream effectors, such as neutrophils, which contribute to the pathology of allergic responses. Methods The effects of PGD 2 , LTE 4 , and their combination on human T H 2 cell gene expression were

Background: The 5-lipoxygenase inhibitor VIA-2291 effectively lowers production of leukotriene metabolites. This study investigates the relations between inflammation, coronary plaque characteristics and left ventricular function in response to treatment with VIA-2291 (Atreleuton) in patients after an acute coronary syndrome (ACS).. Methods: Fifty six post-ACS patients who participated in a randomized trial evaluating the effects of VIA-2291 vs. placebo and underwent cardiac computed tomography angiography were studied. Leukotriene E4 (LTE4), high-sensitivity C-reactive protein (hs-CRP), coronary plaque volume (PV) with vulnerable characteristics (Necrotic Core) and left ventricular ejection fraction (LVEF) were measured at baseline and at 6-month follow-up. The relation of changes in LTE4, hs-CRP, PV and LVEF in response to VIA-2291 was analyzed using conditional logistic regression analyses.. Results: From baseline to 6 months, after adjustment for risk factors, significant reductions in LTE4, ...
BACKGROUND: Inhalation of swine house dust induces acute airway inflammation and increased bronchial responsiveness in healthy subjects. OBJECTIVE: The aim of the study was to investigate whether 5-lipoxygenase products such as leukotrienes may have a role in this reaction. METHODS: Twenty-three healthy subjects were randomised into two groups receiving treatment with either zileuton (600 mg) or placebo four times a day. After 5 days of treatment, all subjects were exposed for 3h in a swine barn. Bronchial responsiveness, exhaled nitric oxide (NO), and mediators in nasal lavage (NAL), blood and urine were measured before and after the exposure. RESULTS: The exposure induced an increased bronchial responsiveness to methacholine in both groups with 2-3 doubling concentration steps, no significant difference between treatments. Leukotriene E(4) in urine increased significantly following exposure in the placebo group from 37.3 (29.1-45.6) (mean (95% confidence interval)) ng/mmol creatinine to 47.7 ...
Eoxin E4, also known as 14,15-leukotriene E4, is an eoxin. Cells make eoxins by metabolizing arachidonic acid with a 15-lipoxygenase enzyme to form 15(S)-hydroperoxyeicosapentaenoic acid (i.e. 15(S)-HpETE). This product is then converted serially to eoxin A4 (i.e. EXA4), EXC4, EXD4, and EXE4 by LTC4 synthase, an unidentified gamma-glutamyltransferase, and an unidentified dipeptidase, respectively, in a pathway which appears similar if not identical to the pathway which forms leukotreines, i.e. LTA4, LTC4, LTD4, and LTE4. This pathway is schematically shown as follows: Arachidonic acid + O2 → 15(S)-HpETE → EXA4 → EXC4 → EXD4 → EXE4 EXA4 is viewed as an intracellular-bound, short-lived intermediate which is rapidly metabolized to the down-stream eoxins. The eoxins down stream of EXA4 are secreted from their parent cells and, it is proposed but not yet proven, serve to regulate allergic responses and the development of certain cancers (see Eoxins).

We have demonstrated presence of the P2Y12 purinergic receptor on human bronchial epithelial cells (HBEC). Apart from acting as an alternative receptor for leukotriene E4, neither its function nor regulation on HBEC is known, not to mention its role in airway remodelling. In this context, we hypothesized that transforming growth factor-β (TGF-β) could affect expression of the P2Y12 receptor on HBEC.. To test the hypothesis, cultured HBEC were exposed to TGF-β1 (0-10 ng/mL) for 1-24 h. The expression of P2Y12 mRNA was evaluated with use of RT-qPCR.. A slight decrease in the expression of P2Y12 not reaching significance was observed at 1-3 h. TGF-β1 significantly suppressed the expression of P2Y12 in HBEC at 12 h (3.5-5.9-fold decrease from control; p=0.001 and p=0.001 at 2 ng/mL and 10 ng/mL, respectively). This decrease persisted by 24 h (3.2-4.0-fold decrease from baseline; p=0.013 and p,0.001 with concentrations of 2 ng/mL and 10 ng/mL, respectively). The decrease was clearly ...
Back in September of 2011, Verizon introduced a new initiative called Network Optimization that only affected unlimited data customers. What is Network Optimization? Well, its a little bit like throttling in that Verizon can slow down your data connection if you meet a list of factors, because they dont want you to ruin the data experience for the rest of their customers.. The thing is, up until now, Network Optimization only affected the 3G connection of those with unlimited data plans. Since most of you are all on 4G LTE now, it really didnt matter much. But according to sources of ours, along with at least one reader who has been notified of the change, LTE will become a part of the "optimization" starting October 1. Like before, this only affects unlimited data customers.. This is what we know. On October 1, Verizon will expand its existing Network Optimization policy to include unlimited data customers who use 4G LTE devices and "have fulfilled their minimum contract term." That ...

Competitor AT&T Mobility plans to cover 150 million POPs with LTE by year-end, with 250 million by the end of 2013, expanding its LTE network to 300 million covered POPs by the end of 2014. Sprint, which began their FD-LTE service in the middle of 2012, expects to cover some 100 markets by the end of the year and 250 by the end of 2013. Sprint is currently limited to 2 X 5 MHz on the PCS band for LTE, which is about half the bandwidth that Verizon and AT&T use on the 700 MHz band which also provides those carriers with increased LTE range. Sprint on Wednesday announced the company will purchase spectrum and 585,000 subscribers from U.S. Cellular for $480 million. Sprint will acquire 20 MHz of PCS spectrum in the 1900 MHz band in several Midwestern markets, including Chicago, and 10 Mhz of PCS spectrum in the St. Louis market ...

TY - JOUR. T1 - Behavior and clinical relevance of histamine and leukotrienes C4 and B4 in grass pollen-induced rhinitis. AU - Miadonna, A.. AU - Tedeschi, A.. AU - Leggieri, E.. AU - Lorini, M.. AU - Folco, G.. AU - Sala, A.. AU - Qualizza, R.. AU - Froldi, M.. AU - Zanussi, C.. PY - 1987. Y1 - 1987. N2 - The release kinetics of histamine and leukotriene C4 (LTC4) and B4 (LTB4) were investigated in nasal secretions of 10 patients with hay fever after antigen challenge. High levels of biologically active histamine were found in nasal washes from asymptomatic allergic and normal subjects. With repeated lavages, the amount of histamine recovered dropped markedly. Grass pollen challenge was followed by a significant (p ,0.05) dose-dependent and time-limited (5 min) increase in histamine level in 7 of 10 patients; these values, however, were lower than those found in basal conditions. In 8 of 10 patients with hay fever, antigen challenge induced a significant (p ,0.05) dose-dependent increase in ...
In the current study, we showed a link between tobacco use and increased levels of urinary PGE-M. Elevated urinary PGE-M levels were found in healthy male tobacco quid chewers. By contrast, a nonstatistically significant increase in urinary PGE-M was observed in healthy female tobacco quid chewers. One likely explanation for the observed increase in urinary PGE-M in men is tobacco quid-related periodontitis or other inflammatory conditions in the oral cavity (42). COX-2 is overexpressed in periodontitis (17). Notably, some studies have suggested a link between periodontitis and increased risk of OSCC (18). Possibly, the observed elevation in urinary PGE-M reflects an increased risk of OSCC in tobacco quid chewers. Why the effect of tobacco quid on urinary PGE-M levels was less dramatic in women is uncertain. Based on history alone, we cannot exclude the possibility that tobacco quid exposure in women was less than in men. In this context, we also note that estrogen possesses anti-inflammatory ...

Later today, Sprint will finally shut down its iDEN network, making room for a wider launch of LTE. No longer will you be able to push-to-talk using your old iDEN device with Sprint suggesting users to pick-up some CDMA Direct Connect phone, instead. Even 911 calls wont work as the network infrastructure is shutting down.. Sprint has been announcing this for quite some time. Starting 2012, visitors to the Now Network stores were no longer being able to buy an iDEN device.. At one time, iDEN was used by some 6 million subscribers many of whom were inherited when Sprint acquired Nextel, which is today officially going to history.. So if you still own an iDEN handset, its time to recycle it and get some more-modern device. There are push-to-talk phones available from a number of carriers - its just finding the one that works best for you.. [Via: TheVerge] ...

Be advised that Cricket doesnt offer the same coverage as regular AT&T. You are on the AT&T prepaid network, not the postpaid network, which excludes partner roaming. Same as GoPhone. That may or may not be a big deal to you, but there are some locales where you cant get reception without partner roaming coverage. Check the prepaid coverage maps to see where those areas are. If you want the same exact coverage as AT&T with 4G-LTE and partner roaming, you should check out Consumer Cellular. Theyre the only ones who offer it, as far as I know. But you may pay more especially if youre a heavy data user, and youll also pay taxes and fees. I checked LTE download speeds and got up to 20 Mb/s so I guess its not capped. You are right though, since I really cant notice any practical difference between HSPA+ speed at about 5 Mb/s and LTE at 20, at least in terms of what I do. So not sure if its worth that much to me to pay extra for LTE. I care more about the coverage when Im travelling. Have run ...

So how does that work? The spec list doesnt say, but I would assume that the Nexus 7 LTE takes microSIM cards, which are the same cards found in almost all phones today outside of the iPhone 5. You could essentially do two things - 1) take the SIM card out of your current phone and drop it into the tablet to get data from day 1, or 2) add the tablet to your current data plan and get its own SIM card. Verizon and AT&T allow you to add on tablets to shared data plans for $10 per month.. "OMG, that means the next Nexus will work on Verizon!" Not so fast. While this single LTE chip is something to get excited about, this doesnt mean that the next Nexus will work on Verizons network. Keep in mind that tablets can do this neat little unlocked LTE trick because they are using data only. If you want a phone to work on Verizons network - at this time - you need it to connect to their 3G CDMA network as well, to you know, make calls. And since CDMA networks are about as locked down as youll find, ...
Results Of 1372 pts entering the LTE, 1134 (82.7%) remained on therapy at time of reporting. Mean baseline RA duration was 8 yrs, TJC and SJC were 30 and 20, respectively, and HAQ-DI was 1.7. Median (range) ABA exposure was 33 (8-44) mths. The incidence rate (IR; events/100 pt-yrs) of serious adverse events for pts treated with SC ABA in the LTE (8.76 [95% CI: 7.71-9.95]) was comparable with that for SC ABA in the DB period (9.02 [6.31-12.90]) and did not increase with increasing exposure. The IR of overall and serious infections in the LTE (44.80 [41.81-48.01] and 1.72 [1.30-2.27], respectively) did not increase vs the DB period (84.62 [74.50-96.11] and 1.48 [0.62-3.56], respectively). Bacterial, viral and hospitalised infections occurred at IRs of 27.28 (25.16-29.57), 18.25 (16.61-20.06) and 1.55 (1.16-2.07) during the LTE. The IR of malignancy did not increase in the LTE (1.19 [0.86-1.66]) vs the DB period (0.59 [0.15-2.36]). Injection-site reactions occurred in 27 (2.0%) pts in the LTE (none ...

Thats right folks, the Droid Bionic is back with another leaked appearance. This time it stars in a video clip that reveals the phones boot sequence, which is followed by an all-important thrill ride / speed test on Verizons LTE network. As if you needed further proof, this Moto reveals itself to pack dual cores, and as you might expect, it sports Motorolas animation-laden skin. What about the LTE test, you ask? It pulls in respectable numbers -- approximately 4.5Mbps down and 1.9Mbps up -- but as youre likely aware, these speeds pale in comparison to what weve seen on the Droid Charge and Revolution. Its entirely possible the test is simply an outlier, so well hope for better scores as the phone approaches its September arrival. Curious for the sneak peak? Youll find the full video after the break ...
When it was first rooted, the HTC EVO 4G LTE had a lot going for it. If you chose to unlock using HTC Dev, kernel flashing was actually possible. While S-Off is like the holy grail of unlocking on any HTC phone, the fact that people could flash whatever they wanted really made it unnecessary for the average ROM flasher. Unfortunately, with the latest set of updates, HTC updated the HBoot and locked it down. Now, EVO LTE users dont have the freedom to flash whatever they want.. Thankfully, theres already a fix for that. XDA Forum Moderator and Recognized Developer xHausx has ported an old favorite from the HTC EVO 3D. Essentially, its a way to modify an update.zip to trick the phone into flashing the kernel anyway.. The method is relatively simple, and xHausx keeps the steps short and sweet. You place the kernel you want to flash in the update.zip, modify the updater-script accordingly, and then sign it. Once done, itll flash the kernel you want it to. Additionally, Xhausx has included a ...
