The 7th International Workshop on Space Solar Cell Calibration and Measurement was held on September 25-27, 2000 in Girdwood, Alaska. Representatives from eight countries discussed international standards for single and multijunction solar cell measurement and calibration methods, round robin intercomparisons, and irradiation test methods for space solar cells. Progress toward adoption of an ISO standard on single junction cells was made. Agreement was reached to begin work on new standards for multijunction cells and irradiation testing. Progress on present single junction round robin measurements was discussed and future multijunction round robins were planned. The next workshop will be held in Germany in October 2001.

Intro Suppressing both androgens and estrogens may circumvent hormone receptor resistance in breast cancer by reducing androgen receptor stimulation. Selective inhibition of the 17, 20-lyase enzyme by orteronel leads to decreased androgen production in men and would be anticipated to reduce estrogen and androgen production in women. Thus, we conducted a phase 1b study of orteronel in postmenopausal women with hormone-receptor positive (HR+) metastatic breast cancer. Methods The primary objective was to identify the recommended phase 2 dose (R2PD) of orteronel in women; escalation was via standard 3+3 design. The initial dose was 300 mg BID and escalated to 400 mg BID. Cycle length was 28 days. Enrolled patients had HR+ metastatic breast cancer and were evaluated every 8 weeks for disease progression. Results Eight heavily pre-treated women enrolled [median age: 57 yo (range 47–73)]. Four received 300 mg BID at dose level 1; 4 received 400 mg BID at dose level 2. No dose limiting toxicities (DLTs) were observed. Adverse events (AE) at least possibly related to orteronel included grade 1–2 nausea (n=4) and bone pain (n=3), and grade 1 hypokalemia, hot flashes, myalgia and AST elevation (n=2). The only grade 3 AE was hypertension (n=2) with 8 patients receiving 34 cycles of treatment. No objective responses were seen; clinical benefit was seen in 2 patients with stable disease for more than 6 months. Serum estrogens and testosterone were suppressed from baseline on both doses of orteronel. Conclusions Orteronel 400 mg BID is well tolerated in postmenopausal women, and significantly suppresses serum estrogens and testosterone. Clinical benefit was seen among heavily pretreated postmenopausal women with HR+ metastatic breast cancer. PMID:27826831

Objective To assess the short‐term tolerability of lorcaserin alone or with two dose regimens of phentermine. Methods This was a 12‐week, randomized, double‐blind, pilot safety study of N = 238 nondiabetic patients with obesity or overweight with ≥1 comorbidity randomized to lorcaserin 10 mg twice daily (BID; LOR BID) alone or with phentermine 15 mg once daily (QD; LOR BID+PHEN QD) or 15 mg twice daily (LOR BID+PHEN BID). Patients reporting ≥ 1 of 9 potentially serotonergic adverse events (AEs), mean weight loss (WL), and ≥5% WL are reported. Results N = 238 were randomized, and N = 235 were treated. N = 94 reported potentially serotonergic AEs: 37.2% LOR BID, 42.3% LOR BID+PHEN QD, and 40.5% LOR BID+PHEN BID. AEs leading to discontinuation were reported approximately twice as often in the LOR BID+PHEN BID group versus the LOR BID group. Mean WL was 3.5 kg/3.3%, 7.0 kg/6.7%, and 7.6 kg/7.2% for LOR BID, LOR BID+PHEN QD, and LOR BID+PHEN BID, respectively. At least 5% WL was achieved by 28.2% LOR BID, 59.0% LOR BID+PHEN QD (P = 0.0002 vs. LOR BID), and 70.9% LOR BID+PHEN BID (P < 0.0001 vs. LOR BID) patients. Conclusions Phentermine added to lorcaserin enhanced short‐term weight loss but did not increase incidence of potentially serotonergic AEs; however, phentermine twice daily increased discontinuation compared to both lorcaserin alone and lorcaserin plus phentermine once daily.

As part of the Healthy, Hunger-Free Kids Act, snacks, and desserts sold in K-12 schools as of the 2014-2015 school year are required to meet the "Smart Snacks" nutritional guidelines. Although studies exist in tracking progress in local and national efforts, the proportion of snack food procured by school districts compliant with the Smart Snacks standard prior to its full implementation is unknown. We repurposed a previously untapped database, Interflex, of public bid records to examine the nutritional quality of snacks and desserts procured by school districts. We selected 8 school districts with at least 90% complete data each year during 2011-2012, 2012-2013, and 2013-2014 school years and at locations across different regions of the United States. We quantified the amount of calories and sugar of each product contained in the won bids based on available online sources and determined whether the produce complied with Smart Snack guidelines. In all 8 districts (snack expenditure analyzed ranging from $152,000 to $4.4 million), at least 50% of snack bids were compliant with the US Department of Agriculture Smart Snacks standard during the 2013-2014 school year. Across sampled districts, we observed a general trend in lower caloric density (kcal per product) and sugar density (grams of sugar per product) over a 3-year period. Many districts across the country have made headway in complying with the Smart Snack guidelines, though gaps remain. © 2016, American School Health Association.

Cleavage by Caspase 8 and Mitochondrial Membrane Association Activate the BH3-only Protein Bid during TRAIL-induced Apoptosis*

The BH3-only protein Bid is known as a critical mediator of the mitochondrial pathway of apoptosis following death receptor activation. However, since full-length Bid possesses potent apoptotic activity, the role of a caspase-mediated Bid cleavage is not established in vivo. In addition, due to the fact that multiple caspases cleave Bid at the same site in vitro, the identity of the Bid-cleaving caspase during death receptor signaling remains uncertain. Moreover, as Bid maintains its overall structure following its cleavage by caspase 8, it remains unclear how Bid is activated upon cleavage. Here, Bid-deficient (Bid KO) colon cancer cells were generated by gene editing, and were reconstituted with wild-type or mutants of Bid. While the loss of Bid blocked apoptosis following treatment by TNF-related apoptosis inducing ligand (TRAIL), this blockade was relieved by re-introduction of the wild-type Bid. In contrast, the caspase-resistant mutant BidD60E and a BH3 defective mutant BidG94E failed to restore TRAIL-induced apoptosis. By generating Bid/Bax/Bak-deficient (TKO) cells, we demonstrated that Bid is primarily cleaved by caspase 8, not by effector caspases, to give rise to truncated Bid (tBid) upon TRAIL treatment. Importantly, despite the presence of an intact BH3 domain, a tBid mutant lacking the mitochondrial targeting helices (α6 and α7) showed diminished apoptotic activity. Together, these results for the first time establish that cleavage by caspase 8 and the subsequent association with the outer mitochondrial membrane are two critical events that activate Bid during death receptor-mediated apoptosis.

Disclosed herein are representative embodiments of methods, apparatus, and systems for distributing a resource (such as electricity) using a resource allocation system. One of the disclosed embodiments is a method for operating a transactive thermostatic controller configured to submit bids to a market-based resource allocation system. According to the exemplary method, a first bid curve is determined, the first bid curve indicating a first set of bid prices for corresponding temperatures and being associated with a cooling mode of operation for a heating and cooling system. A second bid curve is also determined, the second bid curve indicating a second set of bid prices for corresponding temperatures and being associated with a heating mode of operation for a heating and cooling system. In this embodiment, the first bid curve, the second bid curve, or both the first bid curve and the second bid curve are modified to prevent overlap of any portion of the first bid curve and the second bid curve.

Liarozole (R75251) in hormone-resistant prostate cancer patients.

PubMed

Dijkman, G A; Fernandez del Moral, P; Bruynseels, J; de Porre, P; Denis, L; Debruyne, F M

1997-09-15

Liarozole is an imidazole derivative that has been identified as an inhibitor of the cytochrome P450-dependent all-trans retinoid acid (RA) breakdown. RA is one of the principal endogenous compounds that controls growth and differentiation of epithelial tissues in mammals. Fifty-five patients with hormone-resistant prostate cancer in progression, following at least first-line androgen ablation therapy, were evaluated. Thirty-one patients were treated with liarozole 300 mg b.i.d., while 24 patients started with 150 mg b.i.d., which was increased to 300 mg b.i.d. after 4 or 8 weeks. Two patients were not evaluable because they withdrew after initial consent. The WHO performance status was 0 (n = 18), 1 (n = 22), 2 (n = 17), and 3 (n = 6). Most patients (80%) used analgesics. For 11 out of the 53 patients, treatment lasted less than 1 month (they were therefore not evaluable for response) due to: poor compliance (n = 1); early death (n = 3); side-effects (n = 2); and decline of physical condition and continuous progression (n = 4). One patient refused to report for follow-up. In all responders, except one, the dose was increased to 300 mg b.i.d. In 23 of the 42 patients evaluable for response, the pain score improved. In 5 patients the pain score had reduced from 2 or 3 to 0. In 11 out of the 42 patients there was a 1-point improvement of WHO performance status. The prostatic-specific antigen (PSA) response rate was 41%; 15 out of 42 evaluable patients presented a decrease of > or = 50%, whereas PSA normalized in 2 further patients. Most of the side effects mimicked retinoid acid toxicity: cutaneous manifestations (such as dry skin, dry lips, sticky skin, brittle nails, erythema, or itch). All patients experienced one or more of these side effects. Other side effects include nausea, fatigue, and slight alopecia. Liarozole can be an enrichment of the therapeutic armamentarium for treatment of hormone-resistant prostate cancer patients after first-line androgen ablation therapy without serious toxicity.

Prevention and control of major non-communicable diseases in China from 1990 to 2009: results of a two-round Delphi survey.

The aim of this study was to learn about the progress of the prevention and control of major non-communicable diseases (NCDs) in China from 1990 to 2009 and to determine what prevention and control gaps remain based on the opinions of a group of panellists. Sixty-four panellists, who are members of the Subcommittee of the Non-Communicable Diseases, the Expert Committee on Disease Control and Prevention established by China's Ministry of Health in 2010, were invited to participate in an email-based, two-round Delphi survey. In each round, a structured questionnaire was given to participants, who were asked to rate the importance and practical implementation of items relevant to the prevention and control of NCDs over two periods, 1990-1999 and 2000-2009, on a 10-point scale. Of the 64 panellists invited, 20 (31.3%) completed the first-round survey, and, of those, 14 (70.0%) completed the second-round survey. Of the 237 common variables in the two survey rounds, there were 161 (67.9%) and 209 (88.2%) with an interquartile range ≤2 in the first round and second round, respectively. These results indicated a better expert consensus in the second round. There were 92 items in total in the second round of the questionnaire, 88 (95.7%) of which had median importance rating scores of equal to or greater than 7.00. The median scores for the practical implementation items during 2000-2009 were greater than those for the 1990-1999 period. The results indicate improved implementation in the recent decade. China has made progress in the prevention and control of NCDs during the 21st century. However, these intuitive rating results indicate that there are still large action gaps in the fight against epidemic NCDs in China.

Rounded-amoeboid cancer cells use actomyosin contractility driven by Rho-ROCK and JAK-STAT3 to migrate efficiently. It has been suggested that rounded-amoeboid cancer cells do not require matrix metalloproteinases (MMPs) to invade. Here we compare MMP levels in rounded-amoeboid and elongated-mesenchymal melanoma cells. Surprisingly, we find that rounded-amoeboid melanoma cells secrete higher levels of several MMPs, including collagenase MMP-13 and gelatinase MMP-9. As a result, rounded-amoeboid melanoma cells degrade collagen I more efficiently than elongated-mesenchymal cells. Furthermore, using a non-catalytic mechanism, MMP-9 promotes rounded-amoeboid 3D migration through regulation of actomyosin contractility via CD44 receptor. MMP-9 is upregulated in a panel of rounded-amoeboid compared with elongated-mesenchymal melanoma cell lines and its levels are controlled by ROCK-JAK-STAT3 signalling. MMP-9 expression increases during melanoma progression and it is particularly prominent in the invasive fronts of lesions, correlating with cell roundness. Therefore, rounded-amoeboid cells use both catalytic and non-catalytic activities of MMPs for invasion. PMID:24963846

China hones plans for ambitious x-ray probe

NASA Astrophysics Data System (ADS)

Normile, Dennis

2018-03-01

China is raising the stakes in its bid to become a major player in space science. At a kick-off meeting in Beijing last week, China's National Space Science Center began detailed design studies for a satellite that would round out an array of orbiting platforms for probing x-rays from the most violent corners of the cosmos. The enhanced X-Ray Timing and Polarimetry (eXTP) mission would be China's most ambitious space science satellite yet—and its most expensive, with an estimated price tag of $473 million. To pull it off, China is assembling a collaboration involving more than 200 scientists so far from dozens of institutions in 20 countries. If the eXTP mission passes a final review next year, it would launch around 2025.

This article reports the success, or otherwise, of strategies implemented to sustain nursing grand rounds in a large regional health service in North Queensland, Australia. Nursing grand rounds had been introduced in late 2010 to increase nurses' engagement with research and evidence-based practice. Although the format, topics, and purpose of grand rounds have changed, attendees continue to positively evaluate each presentation. However, after 5 years, the initiative has expanded and somewhat modified its focus. This article describes these changes and proposes options for the future progression of this professional development activity. J Contin Educ Nurs. 2016;47(7):316-320.

Urbanisation results in changes to runoff behaviour which, if not addressed, inevitably degrade receiving waters. To date, most stormwater management has focussed on the streetscape and public open space. Given that much of the catchment imperviousness is located on private land, we developed and tested a novel economic instrument (a uniform price auction) for encouraging allotment-scale stormwater retention. We evaluated bids using an integrated environmental benefit index (EBI), based on the ability of the proposed works to reduce runoff frequency, pollutant loads and to reduce potable water demand. The uniform price auction resulted in 1.4 ha of impervious areas being effectively 'disconnected' from the stormwater system. The EBI provided an objective and transparent method of comparing bids, which varied in the type of works proposed (e.g. rainwater tank, rain-garden), the cost and the resulting environmental benefit. Whilst the pilot auction was a success, the public subsidy of works undertaken was around 85%, meaning that property owners a relatively small private benefit in the works. Future auction rounds will be revised to (i) test an EBI which is more focussed on the protection of streams (assessing changes to runoff frequency, baseflow volumes and water quality) and (ii) provide an auction process which is simpler to understand, and provides greater practical support for landholders who wish to undertake works.

Pancreatic cancer is one of the leading causes of cancer-related deaths worldwide. The median survival of locally advanced nonoperable disease is approximately 9 months. 5-FU-based chemoradiotherapy has been the standard treatment. However, the survival benefit of this approach is modest. To improve the efficacy of 5-FU-based chemoradiation therapy, we evaluated the safety and feasibility of the combination of capecitabine and erlotinib with radiotherapy in this group of patients. A traditional "3 + 3" dose escalation design was adopted in the study. A total of four dose levels were designed. For safety purpose, a minus I dose level (-I) was also planned. The -I level consisted of capecitabine 600 mg/m² and erlotinib 50 mg daily, and the remaining four dose levels were as follows: level I: capecitabine 600 mg/m² bid (twice daily); level II: 700 mg/m² bid; level III: 825 mg/m² bid; and level IV: 925 mg/m² bid. Erlotinib was administered at 100 mg daily at all dose levels. Erlotinib and capceitabine were given continuously Monday through Friday concurrent with radiotherapy (50.4 Gy in 28 fractions). A total of 18 patients were consented. Fifteen patients were enrolled and completed therapy. No dose-limiting toxicity was observed. The most frequent side effects were lymphopenia, nausea, vomiting, diarrhea, electrolyte imbalances, and skin rashes. The majority of the toxicities were grade 1 and 2. No objective response was observed. The median progression-free survival was 0.59 years (95 % CI 0.31-1.1), and the median overall survival was 1.1 years (95 % CI 0.62-1.59). The combination of capecitabine and erlotinib with radiotherapy in locally advanced pancreatic cancer is well tolerated and feasible at the dose level of capecitabine 925 mg/m² bid and erlotinib 100 mg daily.

Health information sources accessed by college females: differences between body-image distorted and non-body-image distorted.

PubMed

Nustad, Jill; Adams, Troy; Moore, Monique

2008-01-01

This study examined and compared sources of health-related information accessed by female college students with and without body image distortions, and the believability of those sources. Survey data from the American College Health Association, National College Health Assessment were studied retrospectively (N = 27,648). Body image distorted (BID) and non-BID students' most frequent health information sources were parents (76.1% BID; 77.1% non-BID) and internet (70.3% BID; 69.5% non-BID). Believability was greatest for health educators (90.6% BID; 91.1% non-BID) and lowest for television (14.4% BID; 14.5% non-BID). Health intervention strategies for college women should market to parents and teach recognition of credible internet sources of health information.

Dynamic imaging of interaction between protein 14-3-3 and Bid in living cells

NASA Astrophysics Data System (ADS)

2006-02-01

The 14-3-3 proteins are known to sequester certain pro-apoptotic members of this family. BH3- interacting domain death agonist (Bid) may contribute to tumor necrosis factor α(TNF-α)-induced neuronal death, although regulation by 14-3-3 has not been reported. In this study we examined whether 14-3-3 proteins interact with Bid/tBid during TNF-α-induced cell death. The TNF-αtriggered Bid cleavage and tBid translocated to mitochondria. Human lung adenocarcinoma cells were co-transfected with both CFP-Bid and 14-3-3-YFP plasmids, and the dynamical interaction between the Bid/tBid and 14-3-3 were performed on laser confocal fluorescence microscope in single living cell during TNF-α-induced cell apoptosis. The Bid distribute equally only in the cytoplasm of healthy cells, and the 14-3-3 protein distribute not only in the cytoplasm but also in the nucleus of healthy cells. Our data showed that the tBid aggregate, but the 14-3-3 protein does not aggregate as the tBid, and the 14-3-3 protein separate from the aggregated tBid, implying that the 14-3-3 proteins do not interact with the aggregated tBid after TNF-αtreatment.

To achieve expert consensus on the content of an exercise training program (known as FootyFirst) to prevent lower-limb injuries. Three-round online Delphi consultation process. Community Australian Football (AF). Members of the Australian Football Leagues' Medical Officers (n = 94), physiotherapists (n = 50), and Sports Science (n = 19) Associations were invited to participate through e-mail. Five people with more general expertise in sports-related lower-limb injury prevention were also invited to participate. The primary outcome measure was the level of agreement on the appropriateness of the proposed exercises and progressions for inclusion in FootyFirst. Consensus was reached when ≥75% of experts who responded to each item agreed and strongly agreed, or disagreed and strongly disagreed, that an exercise or its progressions were appropriate to include in FootyFirst. Fifty-five experts participated in at least 1 Delphi round. In round 1, consensus was achieved that the proposed warm-up (run through and dynamic stretches) and the exercises and progressions for hamstring strength and for balance, landing, and changing direction were appropriate to include in FootyFirst. There was also consensus in round 1 that progressions for hip/core strength should be included in FootyFirst. Consensus was reached in round 2 that the revised groin strength and hip strength exercises should be included in FootyFirst. Consensus was reached for the progression of the groin strength exercises in round 3. The formal consensus development process has resulted in an evidence-informed, researcher-developed, exercise-based sports injury prevention program that is expert endorsed and specific to the context of AF. Lower-limb injuries are common in running, kicking, and contact sports like AF. These injuries are often costly to treat, and many have high rates of recurrence, making them challenging to treat clinically. Reducing these injuries is a high priority for players, teams, and medical staff. Exercise programs provide a method for primary prevention of lower-limb injuries, but they have to be evidence based, have currency with sports practitioners/clinicians, and utility for the context in which they are to be used. However, the comprehensive methods and clinical engagement processes used to develop injury prevention exercise programs have not previously been described in detail. This study describes the results of engaging clinicians and sport scientists in the development of a lower-limb sports injury prevention program for community AF, enabling the development of a program that is both evidence informed and considerate of expert clinical opinion.

Study on Comparison of Bidding and Pricing Behavior Distinction between Estimate Methods

NASA Astrophysics Data System (ADS)

Morimoto, Emi; Namerikawa, Susumu

The most characteristic trend on bidding and pricing behavior distinction in recent years is the increasing number of bidders just above the criteria for low-price bidding investigations. The contractor's markup is the difference between the bidding price and the execution price. Therefore, the contractor's markup is the difference between criteria for low-price bidding investigations price and the execution price in the public works bid in Japan. Virtually, bidder's strategies and behavior have been controlled by public engineer's budgets. Estimation and bid are inseparably linked in the Japanese public works procurement system. The trial of the unit price-type estimation method begins in 2004. On another front, accumulated estimation method is one of the general methods in public works. So, there are two types of standard estimation methods in Japan. In this study, we did a statistical analysis on the bid information of civil engineering works for the Ministry of Land, Infrastructure, and Transportation in 2008. It presents several issues that bidding and pricing behavior is related to an estimation method (several estimation methods) for public works bid in Japan. The two types of standard estimation methods produce different results that number of bidders (decide on bid-no bid strategy) and distribution of bid price (decide on mark-up strategy).The comparison on the distribution of bid prices showed that the percentage of the bid concentrated on the criteria for low-price bidding investigations have had a tendency to get higher in the large-sized public works by the unit price-type estimation method, comparing with the accumulated estimation method. On one hand, the number of bidders who bids for public works estimated unit-price tends to increase significantly Public works estimated unit-price is likely to have been one of the factors for the construction companies to decide if they participate in the biddings.

Procurement of construction services: a case study on bidding competition in Singapore public sector contracts

NASA Astrophysics Data System (ADS)

Oo, B. L.; Yan, Y.

2018-04-01

There are many variables that public clients need to consider in their bidding procedure to enhance efficiency in their procurement for construction services. This paper focusses on the competitive bidding process for public sector procurement of construction services in Singapore. A distinctive feature of the Singapore government competitive bidding process is that full bidding feedback information is released to all competing bidders (and public). The specific objectives are: (i) to examine the degree of competition in the construction markets; and (ii) to examine the bidding performance of competing bidders. Based on a collection of bidding data for a 15-month period, the results show the market environment of the Singapore public sector construction contracting is highly competitive with long bidder lists. In selection of contractors, only 50% of the contracts were awarded to lowest bidders. The results also show that the competing contractors can be broadly classified into three groups based on their bidding performance in terms of number of bidding attempts, bidding success rate and bidding competitiveness. These results provide a useful insight into the bidding competition in the Singapore public sector construction contracting, especially to new market entrants and foreign contractors who want to bid for jobs in Singapore.

COMPETITIVE BIDDING IN MEDICARE ADVANTAGE: EFFECT OF BENCHMARK CHANGES ON PLAN BIDS

PubMed Central

Song, Zirui; Landrum, Mary Beth; Chernew, Michael E.

2013-01-01

Bidding has been proposed to replace or complement the administered prices in Medicare pays to hospitals and health plans. In 2006, the Medicare Advantage program implemented a competitive bidding system to determine plan payments. In perfectly competitive models, plans bid their costs and thus bids are insensitive to the benchmark. Under many other models of competition, bids respond to changes in the benchmark. We conceptualize the bidding system and use an instrumental variable approach to study the effect of benchmark changes on bids. We use 2006–2010 plan payment data from the Centers for Medicare and Medicaid Services, published county benchmarks, actual realized fee-for-service costs, and Medicare Advantage enrollment. We find that a $1 increase in the benchmark leads to about a $0.53 increase in bids, suggesting that plans in the Medicare Advantage market have meaningful market power. PMID:24308881

Competitive bidding for Medicare Part B clinical laboratory services.

PubMed

Kautter, John; Pope, Gregory C

2014-06-01

The traditional Medicare fee-for-service program may be able to purchase clinical laboratory test services at a lower cost through competitive bidding. Demonstrations of competitive bidding for clinical laboratory tests have been twice mandated or authorized by Congress but never implemented. This article provides a summary and review of the final design of the laboratory competitive bidding demonstration mandated by the Medicare Modernization Act of 2003. The design was analogous to a sealed bid (first price), clearing price auction. Design elements presented include covered laboratory tests and beneficiaries, laboratory bidding and payment status under the demonstration, composite bids, determining bidding winners and the demonstration fee schedule, and quality under the demonstration. Expanded use of competitive bidding in Medicare, including specifically for clinical laboratory tests, has been recommended in some proposals for Medicare reform. The presented design may be a useful point of departure if Medicare clinical laboratory competitive bidding is revived in the future.

An apoptosis targeted stimulus with nanosecond pulsed electric fields (nsPEFs) in E4 squamous cell carcinoma.

PubMed

Ren, Wei; Beebe, Stephen J

2011-04-01

Stimuli directed towards activation of apoptosis mechanisms are an attractive approach to eliminate evasion of apoptosis, a ubiquitous cancer hallmark. In these in vitro studies, kinetics and electric field thresholds for several apoptosis characteristics are defined in E4 squamous carcinoma cells (SCC) exposed to ten 300 ns pulses with increasing electric fields. Cell death was >95% at the highest electric field and coincident with phosphatidylserine externalization, caspase and calpain activation in the presence and absence of cytochrome c release, decreases in Bid and mitochondria membrane potential (Δψm) without apparent changes reactive oxygen species levels or in Bcl2 and Bclxl levels. Bid cleavage was caspase-dependent (55-60%) and calcium-dependent (40-45%). Intracellular calcium as an intrinsic mechanism and extracellular calcium as an extrinsic mechanism were responsible for about 30 and 70% of calcium dependence for Bid cleavage, respectively. The results reveal electric field-mediated cell death induction and progression, activating pro-apoptotic-like mechanisms and affecting plasma membrane and intracellular functions, primarily through extrinsic-like pathways with smaller contributions from intrinsic-like pathways. Nanosecond second pulsed electric fields trigger heterogeneous cell death mechanisms in E4 SCC populations to delete them, with caspase-associated cell death as a predominant, but not an unaccompanied event.

Cherubism with multiple dental abnormalities: a rare presentation

PubMed Central

Misra, Satya Ranjan; Mishra, Lora; Mohanty, Neeta; Mohanty, Susant

2014-01-01

Cherubism is a progressive, hereditary fibro-osseous lesion exclusively affecting the jaw bones. It is caused by the abnormal functioning of osteoblasts and osteoclasts, leading to replacement of normal bone by cellular fibrous tissue and immature bone, which produces painless progressive growth of the jaw, with a round facial appearance. It was first described in 1933 by Jones as ‘familial multilocular cystic disease of the jaws’. The term ‘cherubism’ was later coined to describe the rounded facial appearance resulting from jaw hypertrophy that was reminiscent of cherubs depicted throughout Renaissance art. The bony lesions generally occur at an early age, affect one or both jaws symmetrically, and grow progressively until puberty. Spontaneous regression is seen in most cases, although surgical re-contouring may be required for others for aesthetic reasons. PMID:25301429

Real-time single cell analysis of Bid cleavage and translocation in cisplatin-induced apoptosis

NASA Astrophysics Data System (ADS)

Liu, Lei; Xing, Da; Pei, Yihui; Chen, Wei R.

2007-02-01

Cancer cell apoptosis can be induced by cisplatin, an efficient anticancer agent. However, its mechanism is not fully understood. Bcl-2 homology domain (BH) 3-only proteins couple stress signals to mitochondrial apoptotic pathways. Calpain-mediated cleavage of the BH3-only protein Bid into a 14 kD truncated protein (tBid) has been implicated in cisplatin-induced apoptotic pathway. We utilized a recombinant fluorescence resonance energy transfer (FRET) Bid probe to determine the kinetics of Bid cleavage during cisplatin-induced apoptosis in ASTC-a-1 cells. The cells were also co-transfected with Bid-CFP and DsRed-Mit to dynamically detect tBid translocation. Cells showed a cleavage of the Bid-FRET probe occurring at about 4-5 h after treated with 20 µM cisplatin. Cleavage of the Bid-FRET probe coincided with a translocation of tBid from the cytosolic to the mitochondria, and the translocation lasted about 1.5 h. Using real-time single-cell analysis, we first observed the kinetics of Bid cleavage and translocation to mitochondria in living cells during cisplatin-induced apoptosis.

Bid purchasing of pharmaceuticals.

Swift, R G; Ryan, M R

1978-11-01

The effects of bid purchasing of drug products by hospitals and the factors to consider in bid purchasing of pharmaceuticals are reviewed; further, the prices available with bid purchasing to a specific hospital in 1974 and 1977 are presented. Factors important for a successful bid purchasing system of pharmaceuticals are: (1) use of a formulary policy, (2) an effective procedure for handling bid purchasing and (3) criteria for evaluation of drug products. Significant differences were found between prices available with and without bid purchasing for 50 nonproprietary drug products in 1974 and for 19 products in 1977. Although monetary savings to hospitals do exist with bid purchasing of pharmaceuticals, the degree of savings is dependent upon the drug usage for that hospital.

Bid Participates in Genotoxic Drug-Induced Apoptosis of HeLa Cells and Is Essential for Death Receptor Ligands' Apoptotic and Synergistic Effects

PubMed Central

Concannon, Caoimhin G.; Rehm, Markus; Kögel, Donat; Prehn, Jochen H. M.

2008-01-01

Background The BH3-only protein Bid is an important component of death receptor-mediated caspase activation. Bid is cleaved by caspase-8 or -10 into t-Bid, which translocates to mitochondria and triggers the release of caspase-activating factors. Bid has also been reported to be cleaved by other proteases. Methodology/Principal Findings To test the hypothesis that Bid is a central mediator of stress-induced apoptosis, we investigated the effects of a small molecule Bid inhibitor on stress-induced apoptosis, and generated HeLa cells deficient for Bid. Stable knockdown of bid lead to a pronounced resistance to Fas/CD95- and TRAIL-induced caspase activation and apoptosis, and significantly increased clonogenic survival. While Bid-deficient cells were equally sensitive to ER stress-induced apoptosis, they showed moderate, but significantly reduced levels of apoptosis, as well as increased clonogenic survival in response to the genotoxic drugs Etoposide, Oxaliplatin, and Doxorubicin. Similar effects were observed using the Bid inhibitor BI6C9. Interestingly, Bid-deficient cells were dramatically protected from apoptosis when subtoxic concentrations of ER stressors, Etoposide or Oxaliplatin were combined with subtoxic TRAIL concentrations. Conclusions/Significance Our data demonstrate that Bid is central for death receptor-induced cell death and participates in anti-cancer drug-induced apoptosis in human cervical cancer HeLa cells. They also show that the synergistic effects of TRAIL in combination with either ER stressors or genotoxic anti-cancer drugs are nearly exclusively mediated via an increased activation of Bid-induced apoptosis signalling.

Dynamic Interaction of cBid with Detergents, Liposomes and Mitochondria

PubMed Central

Bleicken, Stephanie; García-Sáez, Ana J.; Conte, Elena; Bordignon, Enrica

2012-01-01

The BH3-only protein Bid plays a key role in the induction of mitochondrial apoptosis, but its mechanism of action is still not completely understood. Here we studied the two main activation events of Bid: Caspase-8 cleavage and interaction with the membrane bilayer. We found a striking reversible behaviour of the dissociation-association events between the Bid fragments p15 and p7. Caspase-8 cleavage does not induce per se separation of the two Bid fragments, which remain in a stable complex resembling the full length Bid. Detergents trigger a complete dissociation, which can be fully reversed by detergent removal in a range of protein concentrations from 100 µM down to 500 nM. Incubation of cBid with cardiolipin-containing liposomes leads to partial dissociation of the complex. Only p15 (tBid) fragments are found at the membrane, while p7 shows no tendency to interact with the bilayer, but complete removal of p7 strongly increases the propensity of tBid to become membrane-associated. Despite the striking structural similarities of inactive Bid and Bax, Bid does not form oligomers and reacts differently in the presence of detergents and membranes, highlighting clear differences in the modes of action of the two proteins. The partial dissociation of cBid triggered by the membrane is suggested to depend on the strong and specific interaction between p15 and p7. The reversible disassembly and re-assembly of the cBid molecules at the membrane was as well proven by EPR using spin labeled cBid in the presence of isolated mitochondria. The observed dynamic dissociation of the two Bid fragments could allow the assistance to the pore-forming Bax to occur repeatedly and may explain the proposed “hit-and-run" mode of action of Bid at the bilayer.

VS-6063 (also known as defactinib or PF-04554878) is a second-generation inhibitor of focal adhesion kinase and proline-rich tyrosine kinase-2. This phase 1 study evaluated the safety and tolerability, pharmacokinetics, and clinical activity of VS-6063 in Japanese subjects with advanced solid tumor malignancies in a first-in-Asian study setting. VS-6063 was administered orally twice daily (b.i.d.) in 21-day cycles to cohorts of three subjects each with a standard 3 + 3 dose-escalation design until disease progression or unacceptable toxicity. Blood samples for pharmacokinetics were collected on Day 1 and 15. The assessments were performed using CTCAE v4.0 for adverse events (AEs), and the Response Evaluation Criteria In Solid Tumors, version v1.1 (RECIST v1.1) for tumor response. Nine patients were treated across three dose levels (200-600 mg BID). No dose-limiting toxicities were observed at any dose level. Most frequent treatment-related AEs were Grade 1/2 unconjugated hyperbilirubinemia, fatigue, decreased appetite, and diarrhea. Only one subject in the 200 mg BID cohort experienced reversible and transient Grade 3 unconjugated hyperbilirubinemia. PK analyses confirmed that the exposure at the recommended Phase 2 dose (RP2D) of 400 mg BID was comparable with exposures previously reported in non-Japanese subjects. Durable stable disease of approximately 24 weeks was confirmed in two subjects (malignant mesothelioma and rectal cancer). VS-6063 was well tolerated at all dose levels investigated in this first-in-Asian study. These data support the administration of VS-6063 to Japanese subjects at the RP2D in clinical trials involving solid tumor malignancies.

Designing a Successful Bidding Strategy Using Fuzzy Sets and Agent Attitudes

NASA Astrophysics Data System (ADS)

Ma, Jun; Goyal, Madhu Lata

To be successful in a multi-attribute auction, agents must be capable of adapting to continuously changing bidding price. This chapter presents a novel fuzzy attitude-based bidding strategy (FA-Bid), which employs dual assessment technique, i.e., assessment of multiple attributes of the goods as well as assessment of agents' attitude (eagerness) to procure an item in automated auction. The assessment of attributes adapts the fuzzy sets technique to handle uncertainty of the bidding process as well use heuristic rules to determine the attitude of bidding agents in simulated auctions to procure goods. The overall assessment is used to determine a price range based on current bid, which finally selects the best one as the new bid.

In order to select the optimal quasi-bidding project for an investment enterprise, a bidding decision-making model for international PPP projects was established in this paper. Firstly, the literature frequency statistics method was adopted to screen out the bidding decision-making indexes, and accordingly the bidding decision-making index system for international PPP projects was constructed. Then, the group decision-making characteristic root method, the entropy weight method, and the optimization model based on least square method were used to set the decision-making index weights. The optimal quasi-bidding project was thus determined by calculating the consistent effect measure of each decision-making index value and the comprehensive effect measure of each quasi-bidding project. Finally, the bidding decision-making model for international PPP projects was further illustrated by a hypothetical case. This model can effectively serve as a theoretical foundation and technical support for the bidding decision-making of international PPP projects.

Bidding Agents That Perpetrate Auction Fraud

NASA Astrophysics Data System (ADS)

Trevathan, Jarrod; McCabe, Alan; Read, Wayne

This paper presents a software bidding agent that inserts fake bids on the seller's behalf to inflate an auction's price. This behaviour is referred to as shill bidding. Shill bidding is strictly prohibited by online auctioneers, as it defrauds unsuspecting buyers by forcing them to pay more for the item. The malicious bidding agent was constructed to aid in developing shill detection techniques. We have previously documented a simple shill bidding agent that incrementally increases the auction price until it reaches the desired profit target, or it becomes too risky to continue bidding. This paper presents an adaptive shill bidding agent which when used over a series of auctions with substitutable items, can revise its strategy based on bidding behaviour in past auctions. The adaptive agent applies a novel prediction technique referred to as the Extremum Consistency (EC) algorithm, to determine the optimal price to aspire for. The EC algorithm has successfully been used in handwritten signature verification for determining the maximum and minimum values in an input stream. The agent's ability to inflate the price has been tested in a simulated marketplace and experimental results are presented.

Competitive Bidding in a Certain Class of Auctions

NASA Astrophysics Data System (ADS)

Johansson, Mathias

2006-11-01

We consider the problem of determining the amount to bid in a certain type of auctions in which customers submit one sealed bid. The bid reflects the price a customer is willing to pay for one unit of the offered goods. The auction is repeated and at each auction each customer requests a certain amount of goods, an amount that we call the capacity of the customer and that varies among customers and over time. At each auction, only the customer with the largest bid-capacity product obtains any goods. The price paid by the winner equals his/her bid-capacity product, and the amount of goods obtained in return equals the winner's capacity. The auction is repeated many times, with only limited information concerning winning bid-capacity products being announced to the customers. This situation is motivated in for example wireless communication networks in which a possible way of obtaining a desired service level is to use dynamic pricing and competitive bidding. In this application, the capacity is typically uncertain when the bid is made. We derive bidding rules and loss functions for a few typical service requirements.

Multi-scale computational study of the mechanical regulation of cell mitotic rounding in epithelia

PubMed Central

Xu, Zhiliang; Zartman, Jeremiah J.; Alber, Mark

2017-01-01

Mitotic rounding during cell division is critical for preventing daughter cells from inheriting an abnormal number of chromosomes, a condition that occurs frequently in cancer cells. Cells must significantly expand their apical area and transition from a polygonal to circular apical shape to achieve robust mitotic rounding in epithelial tissues, which is where most cancers initiate. However, how cells mechanically regulate robust mitotic rounding within packed tissues is unknown. Here, we analyze mitotic rounding using a newly developed multi-scale subcellular element computational model that is calibrated using experimental data. Novel biologically relevant features of the model include separate representations of the sub-cellular components including the apical membrane and cytoplasm of the cell at the tissue scale level as well as detailed description of cell properties during mitotic rounding. Regression analysis of predictive model simulation results reveals the relative contributions of osmotic pressure, cell-cell adhesion and cortical stiffness to mitotic rounding. Mitotic area expansion is largely driven by regulation of cytoplasmic pressure. Surprisingly, mitotic shape roundness within physiological ranges is most sensitive to variation in cell-cell adhesivity and stiffness. An understanding of how perturbed mechanical properties impact mitotic rounding has important potential implications on, amongst others, how tumors progressively become more genetically unstable due to increased chromosomal aneuploidy and more aggressive.

Overexpression of BID in thyroids of transgenic mice increases sensitivity to iodine-induced autoimmune thyroiditis

PubMed Central

2014-01-01

Background BID functions as a bridge molecule between death-receptor and mitochondrial related apoptotic pathways to amplify apoptotic signaling. Our previous studies have demonstrated a substantial increase in BID expression in primary normal thyroid epithelia cells treated with inflammatory cytokines, including the combination of IFNγ and IL-1β or IFNγ and TNFα. The aim of this study was to determine whether an increase in BID expression in thyroid can induce autoimmune thyroiditis. Methods A transgenic mouse line that expresses human BID in thyroid cells was established by fusing a mouse thyroglobulin (Tg) promoter upstream of human BID (Tg-BID). We tested whether the increased expression of pro-apoptotic BID in thyroid would induce autoimmune thyroiditis, both in the presence and absence of 0.3% iodine water. Results Our data show that Tg-BID mice in a CBA/J (H-2 k) background do not spontaneously develop autoimmune thyroiditis for over a year. However, upon ingestion of iodine in the drinking water, autoimmune thyroiditis does develop in Tg-BID transgenic mice, as shown by a significant increase in anti-Tg antibody and mononuclear cell infiltration in the thyroid glands in 30% of mice tested. Serum T4 levels, however, were similar between iodine-treated Tg-BID transgenic mice and the wild type mice. Conclusions Our data demonstrate that increased thyroid expression of BID facilitates the development of autoimmune thyroiditis induced by iodine uptake. However, the overexpression of BID itself is not sufficient to initiate thyroiditis in CBA/J (H-2 k) mice. PMID:24957380

Mechanical control of mitotic progression in single animal cells

Cattin, Cedric J.; Düggelin, Marcel; Martinez-Martin, David; Gerber, Christoph; Müller, Daniel J.; Stewart, Martin P.

2015-01-01

Despite the importance of mitotic cell rounding in tissue development and cell proliferation, there remains a paucity of approaches to investigate the mechanical robustness of cell rounding. Here we introduce ion beam-sculpted microcantilevers that enable precise force-feedback–controlled confinement of single cells while characterizing their progression through mitosis. We identify three force regimes according to the cell response: small forces (∼5 nN) that accelerate mitotic progression, intermediate forces where cells resist confinement (50–100 nN), and yield forces (>100 nN) where a significant decline in cell height impinges on microtubule spindle function, thereby inhibiting mitotic progression. Yield forces are coincident with a nonlinear drop in cell height potentiated by persistent blebbing and loss of cortical F-actin homogeneity. Our results suggest that a buildup of actomyosin-dependent cortical tension and intracellular pressure precedes mechanical failure, or herniation, of the cell cortex at the yield force. Thus, we reveal how the mechanical properties of mitotic cells and their response to external forces are linked to mitotic progression under conditions of mechanical confinement. PMID:26305930

We present a significant extension of the Brain Imaging Data Structure (BIDS) to support the specific aspects of magnetoencephalography (MEG) data. MEG measures brain activity with millisecond temporal resolution and unique source imaging capabilities. So far, BIDS was a solution to organise magnetic resonance imaging (MRI) data. The nature and acquisition parameters of MRI and MEG data are strongly dissimilar. Although there is no standard data format for MEG, we propose MEG-BIDS as a principled solution to store, organise, process and share the multidimensional data volumes produced by the modality. The standard also includes well-defined metadata, to facilitate future data harmonisation and sharing efforts. This responds to unmet needs from the multimodal neuroimaging community and paves the way to further integration of other techniques in electrophysiology. MEG-BIDS builds on MRI-BIDS, extending BIDS to a multimodal data structure. We feature several data-analytics software that have adopted MEG-BIDS, and a diverse sample of open MEG-BIDS data resources available to everyone. PMID:29917016

Research on bidding quotation game of international project

NASA Astrophysics Data System (ADS)

Lin, Tao; Xu, Xin

2017-04-01

Bidding competition of international projects is more and more fierce currently. However, China started late relatively in the field, it is still lack of experience in the aspect of participation in bidding of international projects, and more effective bidding quotation system is not formed till present. Therefore, China can not win through systemic bidding quotation methods compared with many powerful bidding enterprises in the international field. Research on the field is also focused by many aspects as a result. It is urgent to solve related problems. Game theory is combined for analyzing the effectiveness and operability of bidding quotation models mainly based on current situation of bidding market in China international projects during research process in the paper. The research starts with the perspective of bidders for analyzing their game with tenderers and other bidders. The results have operational value aiming at bidders.

Preliminary Study on Bidding Price Ratio Pattern of Public Works in Taiwan - a Case Study of Bridges, Elevated Highways, Tunnels and Subways

NASA Astrophysics Data System (ADS)

Tseng, Paoshan; Wang, Hanhsiang; Chen, Pingfu; Yeh, Lihsu

2018-01-01

Commonly seen tender bid price information of the public works in Taiwan are the budget amount, floor price, awarding price and so on. The ratio of the awarding price to the floor price or budget price is the so-called bidding price ratio. This ratio is influenced by multifaceted factor interactions and is significant to decision making management in engineering projects. Low bidding price ratio may imply that the budget allocation by the tendering agency is inconsiderate or due to the improper market competition of low price bid rigging. High bidding price ratio in turn may indicate that the allocated budget is relatively low, bidder risks in increased contract execution uncertainty or even exclusive bidding scenario. Therefore, the correlation between the bidding price ratio and the aforementioned tender award information is the key issue of this study. This study gathered the tender information of the civil engineering projects in Taiwan within the past seven years. By performing statistical analysis and clustering the gathered data by bidding price ratio, this study investigated the influencing factors and regulations of bidding price ratio using data mining approach.

1997-01-01

Competitive bidding to derive Medicare fees promises several advantages over administered fee systems. The authors show how incentives for cost savings, quality, and access can be incorporated into bidding schemes, and they report on a study of the clinical laboratory industry conducted in preparation for a bidding demonstration. The laboratory industry is marked by variable concentration across geographic markets and, among firms themselves, by social and economic heterogeneity. The authors conclude that these conditions can be accommodated by available bidding design options and by careful selection of bidding markets. PMID:10180003

Progress on youth reproductive health.

PubMed

1998-06-01

The first round table meeting to review progress in implementing the Programme of Action of the 1994 International Conference on Population and Development was convened in April 1998 to consider progress on adolescent reproductive health and rights. The 30 participants from 24 countries concluded that while many countries have made progress, attitudes still need to be changed among those who continue to believe that provision of reproductive health services to adolescents leads to promiscuity. The topics considered during the meeting included: 1) improving accessibility and quality of information and services; 2) creating an "enabling environment" for adolescent reproductive health; 3) enhancing the role of parents and schools in providing sex education; 4) using national laws and policies to protect youth health and rights; and 5) mobilizing private sector and private foundation resources. The round table recommended that adolescent reproductive health programs 1) involve diverse groups of young people in the development of programs, services, and materials; 2) cooperate with a wide variety of other agencies; 3) encourage open discussions of sexuality; 4) train youth as peer counselors; 5) hire youth as paid staff; 6) use a range of quality communication resources; 7) train health care professionals who deal with adolescents; 8) develop evaluation indicators for social and emotional well-being; 9) increase youth access to the formal health sector; and 10) use the visibility of women's groups to promote young women's interests. The round table also asked UN agencies to strengthen their support for youth programs.

Competitive bidding in Medicare: who benefits from competition?

PubMed

Song, Zirui; Landrum, Mary Beth; Chernew, Michael E

2012-09-01

To conduct the first empirical study of competitive bidding in Medicare. We analyzed 2006-2010 Medicare Advantage data from the Centers for Medicare and Medicaid Services using longitudinal models adjusted for market and plan characteristics. A $1 increase in Medicare's payment to health maintenance organization (HMO) plans led to a $0.49 (P <.001) increase in plan bids, with $0.34 (P <.001) going to beneficiaries in the form of extra benefits or lower cost sharing. With preferred provider organization and private fee-for-service plans included, higher Medicare payments increased bids less ($0.33 per dollar), suggesting more competition among these latter plans. As a market-based alternative to cost control through administrative pricing, competitive bidding relies on private insurance plans proposing prices they are willing to accept for insuring a beneficiary. However, competition is imperfect in the Medicare bidding market. As much as half of every dollar in increased plan payment went to higher bids rather than to beneficiaries. While having more insurers in a market lowered bids, the design of any bidding system for Medicare should recognize this shortcoming of competition.

The Mock LISA Data Challenge Round 3: New and Improved Sources

NASA Technical Reports Server (NTRS)

Baker, John

2008-01-01

The Mock LISA Data Challenges are a program to demonstrate and encourage the development of data-analysis capabilities for LISA. Each round of challenges consists of several data sets containing simulated instrument noise and gravitational waves from sources of undisclosed parameters. Participants are asked to analyze the data sets and report the maximum information they can infer about the source parameters. The challenges are being released in rounds of increasing complexity and realism. Challenge 3. currently in progress, brings new source classes, now including cosmic-string cusps and primordial stochastic backgrounds, and more realistic signal models for supermassive black-hole inspirals and galactic double white dwarf binaries.

Marginal Bidding: An Application of the Equimarginal Principle to Bidding in TAC SCM

NASA Astrophysics Data System (ADS)

Greenwald, Amy; Naroditskiy, Victor; Odean, Tyler; Ramirez, Mauricio; Sodomka, Eric; Zimmerman, Joe; Cutler, Clark

We present a fast and effective bidding strategy for the Trading Agent Competition in Supply Chain Management (TAC SCM). In TAC SCM, manufacturers compete to procure computer parts from suppliers (the procurement problem), and then sell assembled computers to customers in reverse auctions (the bidding problem). This paper is concerned only with bidding, in which an agent must decide how many computers to sell and at what prices to sell them. We propose a greedy solution, Marginal Bidding, inspired by the Equimarginal Principle, which states that revenue is maximized among possible uses of a resource when the return on the last unit of the resource is the same across all areas of use. We show experimentally that certain variations of Marginal Bidding can compute bids faster than our ILP solution, which enables Marginal Bidders to consider future demand as well as current demand, and hence achieve greater revenues when knowledge of the future is valuable.

Investigate the pharmacokinetics of once-daily (QD; 900 mg) and twice-daily (BID; 450 mg) regimens of eslicarbazepine acetate (ESL) and BID (450 mg) regimen of oxcarbazepine (OXC) at steady state in healthy volunteers. Single-center, open-label, randomized, three-way (n = 12) crossover studies in healthy volunteers. Mean eslicarbazepine Cmax,ss (in μm) following ESL QD (87.3) was 33.3% higher (p < 0.05) compared to ESL BID (65.5) and 82.1% higher (p < 0.05) compared to OXC BID (48.0). The mean area under the curve (AUC)ss,0-τ (in μmol h/L) following the last dose of an 8-day repeated dosing was 1156.3, 1117.6, and 968.4 for ESL QD, ESL BID, and OXC BID, respectively. The ratio eslicarbazepine plasma exposure (μmol h/L) to ESL daily-dose (μmol) was 0.381 (1156.3:3037.3), 0.368 (1117.6:3037.3), and 0.271 (968.4:3567.6) for ESL-QD, ESL-BID, and OXC-BID, respectively, which translates into a 40.6% increase in the ability of ESL-QD compared to OXC-BID to deliver into the plasma their major active entity eslicarbazepine. The extent of plasma exposure to ESL minor metabolites: (R)-licarbazepine and oxcarbazepine after ESL-QD was 71.5% and 61.1% lower, respectively, than after OXC-BID. Twenty, 24 and 38 treatment emergent adverse events were reported with ESL-QD, ESL-BID, and OXC-BID, respectively. ESL-QD resulted in 33.3% higher peak plasma concentration (Cmax,ss ) of eslicarbazepine and similar extent of plasma exposure (AUCss,0-τ ) when compared to ESL-BID, which may contribute to the efficacy profile reported with once-daily ESL. In comparison to OXC-BID, administration of ESL-QD resulted in 40.6% increase in the delivery of eslicarbazepine into the plasma as well as a significantly lower systemic exposure to (R)-licarbazepine and oxcarbazepine.

Competitive Bidding in Medicare: Who Benefits From Competition?

PubMed Central

Song, Zirui; Landrum, Mary Beth; Chernew, Michael E.

2012-01-01

Objectives To conduct the first empirical study of competitive bidding in Medicare. Study Design and Methods We analyzed 2006–2010 Medicare Advantage data from the Centers for Medicare & Medicaid Services using longitudinal models adjusted for market and plan characteristics. Results A $1 increase in Medicare's payment to health maintenance organization (HMO) plans led to a $0.49 (P <.001) increase in plan bids, with $0.34 (P <.001) going to beneficiaries in the form of extra benefits or lower cost sharing. With preferred provider organization and private fee-for-service plans included, higher Medicare payments increased bids less ($0.33 per dollar), suggesting more competition among these latter plans. Conclusions As a market-based alternative to cost control through administrative pricing, competitive bidding relies on private insurance plans proposing prices they are willing to accept for insuring a beneficiary. However, competition is imperfect in the Medicare bidding market. As much as half of every dollar in increased plan payment went to higher bids rather than to beneficiaries. While having more insurers in a market lowered bids, the design of any bidding system for Medicare should recognize this shortcoming of competition. PMID:23009305

Monitoring trends in HIV prevalence among young people, aged 15 to 24 years, in Manicaland, Zimbabwe

PubMed Central

2011-01-01

Background In June 2001, the United Nations General Assembly Special Session (UNGASS) set a target of reducing HIV prevalence among young women and men, aged 15 to 24 years, by 25% in the worst-affected countries by 2005, and by 25% globally by 2010. We assessed progress toward this target in Manicaland, Zimbabwe, using repeated household-based population serosurvey data. We also validated the representativeness of surveillance data from young pregnant women, aged 15 to 24 years, attending antenatal care (ANC) clinics, which UNAIDS recommends for monitoring population HIV prevalence trends in this age group. Changes in socio-demographic characteristics and reported sexual behaviour are investigated. Methods Progress towards the UNGASS target was measured by calculating the proportional change in HIV prevalence among youth and young ANC attendees over three survey periods (round 1: 1998-2000; round 2: 2001-2003; and round 3: 2003-2005). The Z-score test was used to compare differences in trends between the two data sources. Characteristics of participants and trends in sexual risk behaviour were analyzed using Student's and two-tailed Z-score tests. Results HIV prevalence among youth in the general population declined by 50.7% (from 12.2% to 6.0%) from round 1 to 3. Intermediary trends showed a large decline from round 1 to 2 of 60.9% (from 12.2% to 4.8%), offset by an increase from round 2 to 3 of 26.0% (from 4.8% to 6.0%). Among young ANC attendees, the proportional decline in prevalence of 43.5% (from 17.9% to 10.1%) was similar to that in the population (test for differences in trend: p value = 0.488) although ANC data significantly underestimated the population prevalence decline from round 1 to 2 (test for difference in trend: p value = 0.003) and underestimated the increase from round 2 to 3 (test for difference in trend: p value = 0.012). Reductions in risk behaviour between rounds 1 and 2 may have been responsible for general population prevalence declines. Conclusions In Manicaland, Zimbabwe, the 2005 UNGASS target to reduce HIV prevalence by 25% was achieved. However, most prevention gains occurred before 2003. ANC surveillance trends overall were an adequate indicator of trends in the population, although lags were observed. Behaviour data and socio-demographic characteristics of participants are needed to interpret ANC trends. PMID:21609449

Pro-apoptotic Bid induces membrane perturbation by inserting selected lysolipids into the bilayer.

PubMed

Goonesinghe, Alexander; Mundy, Elizabeth S; Smith, Melanie; Khosravi-Far, Roya; Martinou, Jean-Claude; Esposti, Mauro D

Bid is a BH3-only member of the Bcl-2 family that regulates cell death at the level of mitochondrial membranes. Bid appears to link the mitochondrial pathway with the death receptor-mediated pathway of cell death. It is generally assumed that the f.l. (full-length) protein becomes activated after proteolytic cleavage, especially by apical caspases like caspase 8. The cleaved protein then relocates to mitochondria and promotes membrane permeabilization, presumably by interaction with mitochondrial lipids and other Bcl-2 proteins that facilitate the release of apoptogenic proteins like cytochrome c. Although the major action may reside in the C-terminus part, tBid (cleaved Bid), un-cleaved Bid also has pro-apoptotic potential when ectopically expressed in cells or in vitro. This pro-apoptotic action of f.l. Bid has remained unexplained, especially at the biochemical level. In the present study, we show that f.l. (full-length) Bid can insert specific lysolipids into the membrane surface, thereby priming mitochondria for the release of apoptogenic factors. This is most effective for lysophosphatidylcholine species that we report to accumulate in mitochondria during apoptosis induction. A Bid mutant that is not pro-apoptotic in vivo is defective in lysophosphatidylcholine-mediated membrane perturbation in vitro. Our results thus provide a biochemical explanation for the pro-apoptotic action of f.l. Bid.

Improving the design of competitive bidding in Medicare Advantage.

PubMed

Cawley, John H; Whitford, Andrew B

2007-04-01

In 2003, Congress passed the Medicare Prescription Drug, Improvement, and Modernization Act, which required that in 2006 the Centers for Medicare and Medicaid Services (CMS) implement a system of competitive bids to set payments for the Medicare Advantage program. Managed care plans now bid for the right to enroll Medicare beneficiaries. Data from the first year of bidding suggest that imperfect competition is limiting the success of the bidding system. This article offers suggestions to improve this system based on findings from auction theory and previous government-run auctions. In particular, CMS can benefit by adjusting its system of competitive bids in four ways: credibly committing to regulations governing bidding; limiting the scope for collusion, entry deterrence, and predatory behavior among bidders; adjusting how benchmark reimbursement rates are set; and accounting for asymmetric information among bidders.

2012-09-01

To evaluate the inherent value of breast cancer therapy a willingness-to-pay (WTP) study was conducted in Korean patients with metastatic breast cancer. Patients were prospectively enrolled from four study centers and completed quality of life questionnaires to reflect their status pre-cancer and their current health status. Clinical and socioeconomic data were collected to characterize the population and utilize during modeling. Patients' WTP for breast cancer treatment was assessed using an open-ended question following three rounds of bidding to better hone in on their maximal WTP, starting with one of three randomly assigned start bids. Predictors of patient WTP was evaluated using linear regression models. Associations between WTP and other parameters were evaluated with correlations. Korean metastatic breast cancer patients were WTP an average of KRW 8 696 329 (US$7555) per month to return to their pre-cancer health state, with those who were recently diagnosed as WTP the most (KRW 12 955 000 [$11 254]). WTP was closely associated with the patient's education level, income, personal financial difficulties, Eastern Cooperative Oncology Group performance status, and their experience of arm symptoms. The results suggest that patients are WTP significant amounts per month for treatment. Breast cancer patients are heavily burdened physically, mentally and financially, and the present study indicated this significant financial burden by disclosing its relationship with WTP. Providing a better understanding of the inherent value of treatment will allow Koreans to better evaluate treatment in the coming era of personalized medicine. © 2012 Wiley Publishing Asia Pty Ltd.

Despite public health efforts, folate deficiency is still largely prevalent in poor, rural populations and continues to cause a large burden of disease. The present paper determines and compares consumer preferences for two folate strategies: folic acid supplementation v. folate biofortification, i.e. the enhancement of the folate content in staple crops. Experimental auctions with non-repeated information rounds are applied to rice in order to obtain willingness-to-pay for folate products. Thereby, GM or non-GM folate-biofortified rice (FBR) is auctioned together with rice that is supplemented with free folic acid pills (FAR). Shanxi Province (China) as a high-risk region of folate deficiency. One hundred and twenty-six women of childbearing age, divided into a school (n 60) and market sample (n 66). Despite differences according to the targeted sample, a general preference for folate biofortification is observed, regardless of the applied breeding technology. Premiums vary between 33·9 % (GM FBR), 36·5 % (non-GM FBR) and 19·0 % (FAR). Zero bidding behaviour as well as the product choice question, respectively, support and validate these findings. The targeted sample, the timing of the auction, the intention to consume GM food and the responsibility for rice purchases are considered key determinants of product choice. A novel ex-post negative valuation procedure shows low consistency in zero bidding. While the low attractiveness of FAR provides an additional argument for the limited effectiveness of past folic acid supplementation programmes, the positive reactions towards GM FBR further support its potential as a possible complementary micronutrient intervention.

Central Gulf of Mexico lease sale draws weak industry response

DOE Office of Scientific and Technical Information (OSTI.GOV)

Koen, A.D.

This paper reports that interest in oil and gas leases in the Gulf of Mexico continued spiraling downward at the latest Minerals Management Service offshore sale. Companies participating in Outer Continental Shelf Sale 139 last week in New Orleans offered 196 bids for 151 blocks in the central Gulf of Mexico. MMS offered 5,213 blocks for lease. The number of tracts receiving bids was the fewest at a central gulf lease sale since 114 tracts garnered high bids totaling $146.4 million at Sale 104 in April 1986. Apparent high bids in Sale 139 totaled $56,195,552, and all bids offered totaledmore » just $65,300,864. Both bidding totals were the lowest in a Gulf of Mexico lease sale since MMS began area-wide gulf leasing at Sale 72 in May 1983. Only 64 of 93 qualified companies participated in Sale 139. Fifty-five companies offered apparent winning bids. By comparison, 123 companies at central gulf lease Sale 131 in March 1991 offered 637 bids totaling $320.5 million for 464 tracts. Apparent high bids last spring totaled $259.9 million. At central gulf lease Sale 123 in March 1990, high bids totaled $427.4 million for 538 tracts. In that sale, BP Exploration Inc. led all bidders, exposing $78 million in 79 high bids, including 60 for deepwater tracts. Since then, interest in deepwater tracts has waned in part because of sagging oil and gas prices as U.S. operators sought bigger prospects outside the U.S. Ironically, Sale 139 was dominated by the U.S. subsidiary of an Italian holding company.« less

To evaluate the efficacy of antimicrobial susceptibility-guided therapy before first-line treatment for infection in patients with dual or triple antibiotic resistance. A total of 1034 patients infected by Helicobacter pylori ( H. pylori ) during 2013-2014 were tested for antimicrobial susceptibility. 157 of 1034 (15%) patients showed resistance to two (127/1034; 12%) and to three (30/1034; 3%) antibiotics. Sixty-eight patients with dual H. pylori -resistance (clarithromycin, metronidazole or levofloxacin) were treated for 10 d with triple therapies: OAL (omeprazole 20 mg b.i.d., amoxicillin 1 g b.i.d., and levofloxacin 500 mg b.i.d.) 43 cases, OAM (omeprazole 20 mg b.i.d., amoxicillin 1 g b.i.d., and metronidazole 500 mg b.i.d.) 12 cases and OAC (omeprazole 20 mg b.id., amoxicillin 1 g b.i.d., and clarithromycin 500 mg b.i.d.) 13 cases based on the antimicrobial susceptibility testing. Twelve patients showed triple H. pylori -resistance (clarithromycin, metronidazole and levofloxacin) and received for 10 d triple therapy with OAR (omeprazole 20 mg b.id., amoxicillin 1 g b.i.d., and rifabutin 150 mg b.i.d.). Eradication was confirmed by 13C-urea breath test. Adverse effects and compliance were assessed by a questionnaire. Intention-to-treat eradication rates were: OAL (97.6%), OAM (91.6%), OAC (92.3%) and OAR (58.3%). Cure rate was significantly higher in naïve patients treated with OAR-10 compared to patients who had two or three previous treatment failures (83% vs 33%). Adverse events rates for OAL, OAM, OAC and OAR were 22%, 25%, 23% and 17%, respectively, all of them mild-moderate. Antimicrobial susceptibility-guided triple therapies during 10 d for first-line treatment leads to an eradication rate superior to 90% in patients with dual antibiotic H. pylori resistance.

Helicobacter pylori is the most important etiologic agent for development of peptic ulcer, chronic gastritis and gastric carcinomas. It is now well established that H. pylori eradication treatment is more cost-effective than acid suppressing therapies alone for the treatment of peptic ulcer disease. However, the comparative cost-effectiveness of various H. pylori eradication regimens is still not clear. This study was designed to make a pharmacoeconomic comparison of different H. pylori eradication regimens in patients with peptic ulcer disease or chronic gastritis, using real-world cost and effectiveness data. Istanbul University Hospital and Marmara University Hospital. A total of 75 patients diagnosed as H. pylori (+) by endoscopy were randomized to receive one of the seven H. pylori treatment protocols. These protocols were as follows: (LAC) = 'lansoprazole 30 mg bid + amoxicillin 1 g bid + clarithromycin 500 mg bid' for 7 days and (OCM) = 'omeprazole 20 mg bid + clarithromycin 250 mg bid + metronidazole 500 mg bid'; (OAM) = 'omeprazole 40 mg qd + amoxicillin 500 mg tid + metronidazole 500 mg tid'; (MARB) = 'metronidazole 250 mg tid + amoxicillin 500 mg qid + ranitidine 300 mg hs + bismuth 300 mg qid'; (OAC) = omeprazole 20 mg bid + amoxicillin 1 g bid + clarithromycin 500 mg bid'; (OCA) = omeprazole 40 mg bid + clarithromycin 500 mg bid + amoxicillin 1 g bid'; (OAB) = 'omeprazole 20 mg bid + amoxicillin 500 mg tid + bismuth 300 mg qid' each for 14 days. Only direct costs were included in the analysis. Effectiveness was measured in terms of "successful eradication". The cost-effectiveness ratios of the regimens were calculated using these effectiveness and cost data. The perspective of the study was assumed as the Government's perspective. Cost-effectiveness ratios of eradication regimens. MARB and OCA regimens were found to be more cost-effective than the other treatment regimens. The eradication rates and cost-effectiveness ratios calculated for these protocols were 90% (158.7 euros) for MARB and 90% (195.8 euros) for OCA regimen. This study confirms the importance of using local pharmacoeconomic data. Analyses such as this give decision-makers the tools to choose a better treatment option which is both highly effective yet and has a low cost.

The Progression of Cell Death Affects the Rejection of Allogeneic Tumors in Immune-Competent Mice – Implications for Cancer Therapy

Large amounts of dead and dying cells are produced during cancer therapy and allograft rejection. Depending on the death pathway and stimuli involved, dying cells exhibit diverse features, resulting in defined physiological consequences for the host. It is not fully understood how dying and dead cells modulate the immune response of the host. To address this problem, different death stimuli were studied in B16F10 melanoma cells by regulated inducible transgene expression of the pro-apoptotic active forms of caspase-3 (revCasp-3), Bid (tBid), and the Mycobacterium tuberculosis-necrosis inducing toxin (CpnTCTD). The immune outcome elicited for each death stimulus was assessed by evaluating the allograft rejection of melanoma tumors implanted subcutaneously in BALB/c mice immunized with dying cells. Expression of all proteins efficiently killed cells in vitro (>90%) and displayed distinctive morphological and physiological features as assessed by multiparametric flow cytometry analysis. BALB/c mice immunized with allogeneic dying melanoma cells expressing revCasp-3 or CpnTCTD showed strong rejection of the allogeneic challenge. In contrast, mice immunized with cells dying either after expression of tBid or irradiation with UVB did not, suggesting an immunologically silent cell death. Surprisingly, immunogenic cell death induced by expression of revCasp-3 or CpnTCTD correlated with elevated intracellular reactive oxygen species (ROS) levels at the time point of immunization. Conversely, early mitochondrial dysfunction induced by tBid expression or UVB irradiation accounted for the absence of intracellular ROS accumulation at the time point of immunization. Although ROS inhibition in vitro was not sufficient to abrogate the immunogenicity in our allo-immunization model, we suggest that the point of ROS generation and its intracellular accumulation may be an important factor for its role as damage associated molecular pattern in the development of allogeneic responses.

Alptekin, Orkun; Alptekin, Nesrin

2017-10-01

Selection of the most suitable contractor is an important process in public construction projects. This process is a major decision which may influence the progress and success of a construction project. Improper selection of contractors may lead to problems such as bad quality of work and delay in project duration. Especially in the construction projects of public buildings, the proper choice of contractor is beneficial to the public institution. Public procurement processes have different characteristics in respect to dissimilarities in political, social and economic features of every country. In Turkey, Turkish Public Procurement Law PPL 4734 is the main regulatory law for the procurement of the public buildings. According to the PPL 4734, public construction administrators have to contract with the lowest bidder who has the minimum requirements according to the criteria in prequalification process. Public administrators are not sufficient for selection of the proper contractor because of the restrictive provisions of the PPL 4734. The lowest bid method does not enable public construction administrators to select the most qualified contractor and they have realised the fact that the selection of a contractor based on lowest bid alone is inadequate and may lead to the failure of the project in terms of time delay Eand poor quality standards. In order to evaluate the overall efficiency of a project, it is necessary to identify selection criteria. This study aims to focus on identify importance of other criteria besides lowest bid criterion in contractor selection process of PPL 4734. In this study, a survey was conducted to staff of Department of Construction Works of Eskisehir Osmangazi University. According to TOPSIS (Technique for Order Preference by Similarity to the Ideal Solution) for analysis results, termination of construction work in previous tenders is the most important criterion of 12 determined criteria. The lowest bid criterion is ranked in rank 5.

Hospital materials managers need to be aware of actions that constitute legal acceptance.

PubMed

Decker, R

1990-12-01

A hospital invited bids for building materials for a hospital construction project. A supplier submitted a bid which asked the hospital to sign and return a trade association form contract. The hospital didn't return the form but used the supplier's bid as part of the general contract for the entire project and notified the supplier and the general contractor. Later, the supplier submitted a higher bid for the same material contending that the hospital hadn't accepted the first bid as they hadn't followed the instructions. The hospital materials manager feels that the bid was properly accepted. In this dialogue, Dr. Decker reviews the legal issues involved in the different ways of accepting an offer.

Atrial fibrillation (AF) requires arrhythmogenic changes in atrial ion channels/receptors and usually altered atrial structure. AF is commonly treated with antiarrhythmic drugs; the most effective block many ion channels/receptors. Modest efficacy, intolerance, and safety concerns limit current antiarrhythmic drugs. We hypothesized that combining agents with multiple anti-AF mechanisms at reduced individual drug doses might produce synergistic efficacy plus better tolerance/safety. HARMONY tested midrange ranolazine (750 mg BID) combined with 2 reduced dronedarone doses (150 mg BID and 225 mg BID; chosen to reduce dronedarone's negative inotropic effect-see text below) over 12 weeks in 134 patients with paroxysmal AF and implanted pacemakers where AF burden (AFB) could be continuously assessed. Patients were randomized double-blind to placebo, ranolazine alone (750 mg BID), dronedarone alone (225 mg BID), or one of the combinations. Neither placebo nor either drugs alone significantly reduced AFB. Conversely, ranolazine 750 mg BID/dronedarone 225 mg BID reduced AFB by 59% versus placebo (P=0.008), whereas ranolazine 750 mg BID/dronedarone 150 mg BID reduced AFB by 43% (P=0.072). Both combinations were well tolerated. HARMONY showed synergistic AFB reduction by moderate dose ranolazine plus reduced dose dronedarone, with good tolerance/safety, in the population enrolled.

Objective We examine the mediating role of body image dissatisfaction (BID) on the association between obesity and depression and the variation of this association as a function of years of education among a population-based sample of women aged 40–65 years. Methods A series of sample-weighted logistic regression models were used to estimate the associations between obesity, BID, and depression, stratified by educational attainment. Data were obtained from a structured telephone interview of 4543 female health plan enrollees, including self-reported height and weight, the Patient Health Questionnaire assessment of depression, and a single-item measure of BID. Results Among those with <16 years of education, in both the unadjusted and adjusted models, obesity and BID were significantly associated with depression. Similarly, among those with ≥16 years of education, obesity and BID were significantly associated with depression in the unadjusted models. However, in the adjusted model, only BID was associated with depression. A formal test for mediation suggests that the association between obesity and depression was mediated by BID regardless of level of education. Conclusions Our data suggest that BID-mediated the obesity-depression association. In addition, obesity and BID may be salient risk factors for depression among middle-aged women as a function of the level of education. PMID:21109045

Evolutionary Dynamics of Biological Auctions

Chatterjee, Krishnendu; Reiter, Johannes G.; Nowak, Martin A.

2011-01-01

Many scenarios in the living world, where individual organisms compete for winning positions (or resources), have properties of auctions. Here we study the evolution of bids in biological auctions. For each auction n individuals are drawn at random from a population of size N. Each individual makes a bid which entails a cost. The winner obtains a benefit of a certain value. Costs and benefits are translated into reproductive success (fitness). Therefore, successful bidding strategies spread in the population. We compare two types of auctions. In “biological all-pay auctions” the costs are the bid for every participating individual. In “biological second price all-pay auctions” the cost for everyone other than the winner is the bid, but the cost for the winner is the second highest bid. Second price all-pay auctions are generalizations of the “war of attrition” introduced by Maynard Smith. We study evolutionary dynamics in both types of auctions. We calculate pairwise invasion plots and evolutionarily stable distributions over the continuous strategy space. We find that the average bid in second price all-pay auctions is higher than in all-pay auctions, but the average cost for the winner is similar in both auctions. In both cases the average bid is a declining function of the number of participants, n. The more individuals participate in an auction the smaller is the chance of winning, and thus expensive bids must be avoided. PMID:22120126

This double-blind, placebo-controlled phase 3 study was designed to compare efficacy and safety of abiraterone acetate + prednisone (abiraterone) to prednisone alone in chemotherapy-naïve, asymptomatic or mildly symptomatic metastatic castration-resistant prostate cancer (mCRPC) patients from China, Malaysia, Thailand and Russia. Adult chemotherapy-naïve patients with confirmed prostate adenocarcinoma, Eastern Cooperative Oncology Group (ECOG) performance status (PS) grade 0-1, ongoing androgen deprivation (serum testosterone <50 ng/dL) with prostate specific antigen (PSA) or radiographic progression were randomized to receive abiraterone acetate (1000 mg, QD) + prednisone (5 mg, BID) or placebo + prednisone (5 mg, BID), until disease progression, unacceptable toxicity or consent withdrawal. Primary endpoint was improvements in time to PSA progression (TTPP). Totally, 313 patients were randomized (abiraterone: n  = 157; prednisone: n  = 156); and baseline characteristics were balanced. At clinical cut-off (median follow-up time: 3.9 months), 80% patients received treatment (abiraterone: n  = 138, prednisone: n  = 112). Median time to PSA progression was not reached with abiraterone versus 3.8 months for prednisone, attaining 58% reduction in PSA progression risk (HR = 0.418; p  < 0.0001). Abiraterone-treated patients had higher confirmed PSA response rate (50% vs. 21%; relative odds = 2.4; p  < 0.0001) and were 5 times more likely to achieve radiographic response than prednisone-treated patients (22.9% vs.  4.8%, p  = 0.0369). Median survival was not reached. Most common (≥10% abiraterone vs.  prednisone-treated) adverse events: bone pain (7% vs. 14%), pain in extremity (6% vs. 12%), arthralgia (10% vs. 8%), back pain (7% vs. 11%), and hypertension (15% vs. 14%). Interim analysis confirmed favorable benefit-to-risk ratio of abiraterone in chemotherapy-naïve men with mCRPC, consistent with global study, thus supporting use of abiraterone in this patient population.

The effect of business improvement districts on the incidence of violent crimes

2010-01-01

Objective To examine whether business improvement districts (BID) contributed to greater than expected declines in the incidence of violent crimes in affected neighbourhoods. Method A Bayesian hierarchical model was used to assess the changes in the incidence of violent crimes between 1994 and 2005 and the implementation of 30 BID in Los Angeles neighbourhoods. Results The implementation of BID was associated with a 12% reduction in the incidence of robbery (95% posterior probability interval −2 to 24) and an 8% reduction in the total incidence of violent crimes (95% posterior probability interval −5 to 21). The strength of the effect of BID on robbery crimes varied by location. Conclusion These findings indicate that the implementation of BID can reduce the incidence of violent crimes likely to result in injury to individuals. The findings also indicate that the establishment of a BID by itself is not a panacea, and highlight the importance of targeting BID efforts to crime prevention interventions that reduce violence exposure associated with criminal behaviours.

Diagnosis and Management of Iliac Artery Endofibrosis: Results of a Delphi Consensus Study.

PubMed

2016-07-01

Iliac endofibrosis is a rare condition that may result in a reduction of blood flow to the lower extremity in young, otherwise healthy individuals. The data to inform everyday clinical management are weak and therefore a Delphi consensus methodology was used to explore areas of consensus and disagreement concerning the diagnosis and management of patients with suspected iliac endofibrosis. A three-round Delphi questionnaire approach was used among vascular surgeons, sports physicians, sports scientists, radiologists, and clinical vascular scientists with experience of treating this condition to explore diagnosis and clinical management issues for patients with suspected iliac artery endofibrosis. Analysis is based on 18 responses to round 2 and 14 responses to round 3, with agreement reported when 70% of respondents were in agreement. Initially there was agreement on the typical symptoms at presentation and the need for an exercise test in the diagnosis. Round 3 clarified that duplex ultrasound was a useful tool in the diagnosis of endofibrosis. There was consensus on the most appropriate type of surgery (endarterectomy and vein patch) and that endovascular interventions were inadvisable. The final round helped to inform aspects of the natural history and post-operative surveillance. Progression of the disease was likely with continued exercise but cessation may prevent progression. Surveillance after surgery is generally recommended yearly with at least a clinical assessment. There is broad agreement about the presenting symptoms and the investigations required to confirm (or exclude) the diagnosis of iliac endofibrosis. There was consensus on the surgical approach to repair. Disagreement existed about the specific diagnostic criteria that should be applied during non-invasive testing and about post-operative care and resumption of exercise.

A comparison of pay-as-bid and marginal pricing in electricity markets

NASA Astrophysics Data System (ADS)

Ren, Yongjun

This thesis investigates the behaviour of electricity markets under marginal and pay-as-bid pricing. Marginal pricing is believed to yield the maximum social welfare and is currently implemented by most electricity markets. However, in view of recent electricity market failures, pay-as-bid has been extensively discussed as a possible alternative to marginal pricing. In this research, marginal and pay-as-bid pricing have been analyzed in electricity markets with both perfect and imperfect competition. The perfect competition case is studied under both exact and uncertain system marginal cost prediction. The comparison of the two pricing methods is conducted through two steps: (i) identify the best offer strategy of the generating companies (gencos); (ii) analyze the market performance under these optimum genco strategies. The analysis results together with numerical simulations show that pay-as-bid and marginal pricing are equivalent in a perfect market with exact system marginal cost prediction. In perfect markets with uncertain demand prediction, the two pricing methods are also equivalent but in an expected value sense. If we compare from the perspective of second order statistics, all market performance measures exhibit much lower values under pay-as-bid than under marginal pricing. The risk of deviating from the mean is therefore much higher under marginal pricing than under pay-as-bid. In an imperfect competition market with exact demand prediction, the research shows that pay-as-bid pricing yields lower consumer payments and lower genco profits. This research provides quantitative evidence that challenges some common claims about pay-as-bid pricing. One is that under pay-as-bid, participants would soon learn how to offer so as to obtain the same or higher profits than what they would have obtained under marginal pricing. This research however shows that, under pay-as-bid, participants can at best earn the same profit or expected profit as under marginal pricing. A second common claim refuted by this research is that pay-as-bid does not provide correct price signals if there is a scarcity of generation resources. We show that pay-as-bid does provide a price signal with such characteristics and furthermore argue that the price signal under marginal pricing with gaming may not necessarily be correct since it would then not reflect a lack of generation capacity but a desire to increase profit.

Therapeutic efficacy of improved α-fetoprotein promoter-mediated tBid delivered by folate-PEI600-cyclodextrin nanopolymer vector in hepatocellular carcinoma

SNPs in human AFP promoter are associated with serum AFP levels in hepatocellular carcinoma (HCC), suggesting that AFP promoter variants may generate better transcriptional activities while retaining high specificity to AFP-producing cells. We sequenced human AFP promoters, cloned 15 different genotype promoters and tested their reporter activities in AFP-producing and non-producing cells. Among various AFP variant fragments tested, EA4D exhibited the highest reporter activity and thus was selected for the further study. EA4D was fused with tBid and coupled with nano-particle vector (H1) to form pGL3-EA4D-tBid/H1. pGL3-EA4D-tBid/H1 could express a high level of tBid while retain the specificity to AFP-producingmore » cells. In a HCC tumor model, application of pGL3-EA4D-tBid/H1 significantly inhibited the growth of AFP-producing-implanted tumors with minimal side-effects, but had no effect on non-AFP-producing tumors. Furthermore, pGL3-EA4D-tBid/H1 could significantly sensitize HCC cells to sorafenib, an approved anti-HCC agent. Collectively, pGL3-EA4D-tBid/H1, a construct with the AFP promoter EA4D and the novel H1 delivery system, can specifically target and effectively suppress the AFP-producing HCC. This new therapeutic tool shows little toxicity in vitro and in vivo and it should thus be safe for further clinical tests. - Highlights: • The nano-particle vector H1 has advantages in mediating gene therapy construct pGL3-EA4D-tBid for HCC treatment. • pGL3-EA4D-tBid/H1, a construct with the AFP promoter EA4D, can specifically target the AFP-producing HCC. • pGL3-EA4D-tBid/H1effectively suppresses the proliferation and growth of AFP-producing HCC. • This novel pGL3-EA4D-tBid/H1 therapeutic tool shows little toxicity in vitro and in vivo.« less

Twice-daily dosing of a repaglinide/metformin fixed-dose combination tablet provides glycaemic control comparable to rosiglitazone/metformin tablet.

To assess the use of a new repaglinide/metformin fixed-dose combination (FDC) tablet for the treatment of type 2 diabetes. In this 26-week, multicentre, open-label, parallel-group trial, subjects poorly controlled with mono- or dual-oral antidiabetic therapy were randomized 1 : 1 : 1 to receive a repaglinide/metformin FDC tablet either two times daily (BID) or three times daily (TID) or a rosiglitazone/metformin FDC tablet BID. The primary objective comprised two hypotheses tested in a hierarchical order: (i) that treatment with the repaglinide/metformin FDC BID is non-inferior to that of a rosiglitazone/metformin FDC tablet BID as measured by changes in haemoglobin A1c (HbA1c) (results presented here) and (ii) if true, that treatment with the repaglinide/metformin FDC BID was non-inferior to that of the repaglinide/metformin FDC TID as measured by changes in HbA1c (results presented in a companion paper). Additional efficacy and safety end-points were also assessed. Of the 561 subjects randomized, 383 completed the study. Reductions in HbA1c values became apparent at earlier times for repaglinide/metformin FDC BID treatment than rosiglitazone/metformin FDC BID, and final changes in HbA1c were not significantly different between treatment arms (p = 0.8186); thus, the predefined statistical criterion for non-inferiority was met. Overall adverse event profiles were comparable between treatment groups, and no major hypoglycaemic episodes were reported during the study. The repaglinide/metformin FDC BID regimen showed efficacy that was non-inferior to that of the rosiglitazone/metformin FDC BID regimen currently in clinical use and a more rapid reduction of HbA1c values. Thus, repaglinide/metformin FDC BID is a clinically feasible alternative to rosiglitazone/metformin FDC BID.

Human islet cells are killed by BID-independent mechanisms in response to FAS ligand.

Cell death via FAS/CD95 can occur either by activation of caspases alone (extrinsic) or by activation of mitochondrial death signalling (intrinsic) depending on the cell type. The BH3-only protein BID is activated in the BCL-2-regulated or mitochondrial apoptosis pathway and acts as a switch between the extrinsic and intrinsic cell death pathways. We have previously demonstrated that islets from BID-deficient mice are protected from FAS ligand-mediated apoptosis in vitro. However, it is not yet known if BID plays a similar role in human beta cell death. We therefore aimed to test the role of BID in human islet cell apoptosis immediately after isolation from human cadaver donors, as well as after de-differentiation in vitro. Freshly isolated human islets or 10-12 day cultured human islet cells exhibited BID transcript knockdown after BID siRNA transfection, however they were not protected from FAS ligand-mediated cell death in vitro as determined by DNA fragmentation analysis using flow cytometry. On the other hand, the same cells transfected with siRNA for FAS-associated via death domain (FADD), a molecule in the extrinsic cell death pathway upstream of BID, showed significant reduction in cell death. De-differentiated islets (human islet-derived progenitor cells) also demonstrated similar results with no difference in cell death after BID knockdown as compared to scramble siRNA transfections. Our results indicate that BID-independent pathways are responsible for FAS-dependent human islet cell death. These results are different from those observed in mouse islets and therefore demonstrate potentially alternate pathways of FAS ligand-induced cell death in human and mouse islet cells.

To explore the new mechanisms of tamoxifen (TAM) in the treatment for patients with idiopathic oligoasthenospermia-antioxidation. In a prospective, randomized, controlled clinical trial, 120 cases of idiopathic oligoasthenospermia were enrolled and randomly assigned to the indomethacin group (n = 60) treated with indomethacin (25 mg, bid) and TAM group (n = 60) treated with TAM (10 mg, bid) for 3 months. Before and after treatment, we evaluated semen parameters, serum malondialdehyde (MDA) and total antioxidant capacity (TAC), seminal plasma MDA and TAC, spermatozoa intracellular reactive oxygen species (ROS), sperm succinate dehydrogenase (SDH) activity, sperm mitochondrial membrane potential (MMP), and sperm adenosine triphosphate (ATP) content. The independent t test and one-way repeated measures analysis of variance were used to compare the variables between and within two groups. In the indomethacin group, the percentage of progressive motile sperms, total motility, sperm MMP, and ATP content were increased significantly after 3-month treatment (P < 0.05). In the TAM group, total sperm count, sperm concentration, the percentage of progressive motile sperms, total motility, serum and seminal plasma TAC, sperm MMP, and ATP content were significantly improved or increased (P < 0.05), while spermatozoa intracellular ROS was significantly decreased (P < 0.05). Compared to the indomethacin group, TAM treatment showed better improvement in total sperm count, sperm concentration, serum TAC, seminal plasma TAC, spermatozoa intracellular ROS, and sperm SDH activity. TAM treatment can significantly improve sperm quality, which is achieved through alleviating oxidative stress, improving sperm mitochondrial functionality, and subsequently increasing sperm motility.

Alzheimer's disease (AD) is a neurodegenerative disorder highlighted by progressive declines in cognitive and functional abilities. Our objective was to assess the general public's maximum willingness to pay ((M)WTP) for an increase in annual personal income taxes to fund unrestricted access to AD medications. We randomly recruited 500 Canadians nationally and used computer-assisted telephone interviewing to administer a questionnaire. The questionnaire contained four 'efficacy' scenarios describing an AD medication as capable of symptomatically treating cognitive decline or modifying disease progression. The scenarios also described the medication as having no adverse effects or a 30% chance of adverse effects. We randomized participants to order of scenarios and willingness-to-pay bid values; (M)WTP for each scenario was the highest accepted bid for that scenario. We conducted linear regression and bootstrap sensitivity analyses to investigate potential determinants of (M)WTP. Mean (M)WTP was highest for the 'disease modification/no adverse effects' scenario ($Can130.26) and lowest for the 'symptomatic treatment/30% chance of adverse effects' scenario ($Can99.16). Bootstrap analyses indicated none of our potential determinants (e.g. age, sex) were associated with participants' (M)WTP. The general public is willing to pay higher income taxes to fund unrestricted access to AD (especially disease-modifying) medications. Consequently, the public should favour placing new AD medications on public drug plans. As far as we are aware, no other study has elicited the general public's willingness to pay for AD medications.

The BH3 interacting-domain death agonist (BID) is a pro-apoptotic protein involved in death receptor-induced and mitochondria-mediated apoptosis. Recently, it has also been suggested that BID is involved in the regulation of inflammatory responses in the central nervous system. We found that BID deficiency protected organotypic hippocampal slice cultures in vitro from neuronal injury induced by oxygen-glucose deprivation. In vivo, BID-knockout (KO) mice and wild type (WT) mice were subjected to 60 min of transient middle cerebral artery occlusion (tMCAO) to induce focal cerebral ischemia, and allowed to recover for 24 h. Infarct volumes and functional outcome were assessed and the inflammatory response was evaluated using immunofluorescence, Western blotting, quantitative PCR (qPCR) and Mesoscale multiplex analysis. We observed no difference in the infarct volume or neurological outcome between BID-KO and WT mice. The inflammatory response was reduced by BID deficiency as indicated by a change in microglial/leukocyte response. In conclusion, our data suggest that BID deficiency is neuroprotective in an in vitro model and modulates the inflammatory response to focal cerebral ischemia in vivo. However, this is not translated into a robust neuroprotection in vivo. PMID:26869884

Body Image Disturbance in 1000 Male Appearance and Performance Enhancing Drug Users

Body image disturbance (BID) among men has only recently become a phenomenon of clinical significance with noted heterogeneity in the behavioral consequences of these disturbances. The degree of heterogeneity among appearance and performance enhancing drug (APED) users is unknown and an empirically derived framework for studying BID is necessary. 1000 APED users were recruited via the Internet and they completed a comprehensive online assessment APED use patterns, motivations, consequences, and BID. Data were evaluated using latent trait, latent class, and factor mixture models. Model results were validated using a range of covariates including cycle characteristics, age, APED history, and APED risk. A 1-Factor, 4-Class model provided the best fit to the data with Class 1 scoring the highest on all measures of BID and Class 4 the lowest on all measures. Class 2 differed in their preference for being lean over muscular and Class 3 preferred adding mass and size. Each class was associated with unique risks, APED history, and training identity. Not all APED users suffer from significant BID and there are unique profiles for those with elevated BID. Future research on male BID should account for this structure in order to better define relevant diagnostic categories and evaluate the clinical significance of BID. PMID:20110092

A Robust Open Ascending-price Multi-unit Auction Protocol against False-name Bids

NASA Astrophysics Data System (ADS)

Iwasaki, Atsushi; Yokoo, Makoto; Terada, Kenji

This paper develops a new ascending-price multi-unit auction protocol that has following characteristics: (i) it has an open format, (ii) sincere bidding is an equilibrium strategy even if the marginal utilities of each agent can increase and agents can submit false-name bids. False-name bids are bids submitted under fictitious names such as multiple e-mail addresses, which can be done easily in the Internet. This is the first protocol that has these two characteristics. We show that our new protocol outperforms an existing protocol, which satisfies (ii), with respect to the social surplus and the seller's revenue.

In professional sporting events, rating competitors before tournament start is a well-known approach to distinguish the favorite team and the weaker teams. Various methodologies are used to rate competitors. In this paper, we explore four ways to rate competitors; least squares rating, maximum likelihood strength ratio, standing points in large round robin simulation and previous league rank position. The tournament metric we used to evaluate different types of rating approach is tournament outcome characteristics measure. The tournament outcome characteristics measure is defined by the probability that a particular team in the top 100q pre-tournament rank percentile progress beyond round R, for all q and R. Based on simulation result, we found that different rating approach produces different effect to the team. Our simulation result shows that from eight teams participate in knockout standard seeding, Perak has highest probability to win for tournament that use the least squares rating approach, PKNS has highest probability to win using the maximum likelihood strength ratio and the large round robin simulation approach, while Perak has the highest probability to win a tournament using previous league season approach.

Welfare Impact of Virtual Trading on Wholesale Electricity Markets

NASA Astrophysics Data System (ADS)

Giraldo, Juan S.

Virtual bidding has become a standard feature of multi-settlement wholesale electricity markets in the United States. Virtual bids are financial instruments that allow market participants to take financial positions in the Day-Ahead (DA) market that are automatically reversed/closed in the Real-Time (RT) market. Most U.S. wholesale electricity markets only have two types of virtual bids: a decrement bid (DEC), which is virtual load, and an increment offer (INC), which is virtual generation. In theory, financial participants create benefits by seeking out profitable bidding opportunities through arbitrage or speculation. Benefits have been argued to take the form of increased competition, price convergence, increased market liquidity, and a more efficient dispatch of generation resources. Studies have found that price convergence between the DA and RT markets improved following the introduction of virtual bidding into wholesale electricity markets. The improvement in price convergence was taken as evidence that market efficiency had increased and many of the theoretical benefits realized. Persistent price differences between the DA and RT markets have led to calls to further expand virtual bidding as a means to address remaining market inefficiencies. However, the argument that price convergence is beneficial is extrapolated from the study of commodity and financial markets and the role of futures for increasing market efficiency in that context. This viewpoint largely ignores details that differentiate wholesale electricity markets from other commodity markets. This dissertation advances the understanding of virtual bidding by evaluating the impact of virtual bidding based on the standard definition of economic efficiency which is social welfare. In addition, an examination of the impacts of another type of virtual bid, up-to-congestion (UTC) transactions is presented. This virtual product significantly increased virtual bidding activity in the PJM interconnection market since it became available to be used by financial traders in September 2010. Stylized models are used to determine the optimal bidding strategy for the different virtual bids under different scenarios. The welfare analysis shows that the main impact of virtual bidding is surplus reallocation and that the impact on market efficiency is small by comparison. The market structure is such that it is more likely to see surplus transfers from consumers to producers. The results also show that outcomes with greater price convergence as a result of virtual bidding activity were not necessarily more efficient, nor do they always correct surplus distribution distortions that result from bias in the DA expectation of RT load. Compared to INCs and DECs, the UTC analysis showed that UTCs do not have the same self-corrective incentives towards price convergence and are less likely to lead to nodal price convergence or correct for surplus distribution distortions caused by uncertainty and bias in the DA expectation of RT load. Additionally, the analysis showed that UTCs allow financial traders to engage in low risk high volume trading strategies that, while profitable, may have little to no impact on price convergence or market efficiency.

Smarter than others? Conjectures in lowest unique bid auctions.

Research concerning various types of auctions, such as English auctions, Dutch auctions, highest-price sealed-bid auctions, and second-price sealed-bid auctions, is always a topic of considerable interest in interdisciplinary fields. The type of auction, known as a lowest unique bid auction (LUBA), has also attracted significant attention. Various models have been proposed, but they often fail to explain satisfactorily the real bid-distribution characteristics. This paper discusses LUBA bid-distribution characteristics, including the inverted-J shape and the exponential decrease in the upper region. The authors note that this type of distribution, which initially increases and later decreases, cannot be derived from the symmetric Nash equilibrium framework based on perfect information that has previously been used. A novel optimization model based on non-perfect information is presented. The kernel of this model is the premise that agents make decisions to achieve maximum profit based on imaginary information or assumptions regarding the behavior of others.

To receive pharmacokinetics, safety, and anti-tumor activity of icotinib, a novel epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI), in patients with advanced non-small-cell lung cancer (NSCLC). Patients (n=40) with advanced NSCLC were enrolled to receive escalating doses of icotinib, which was administrated on Day 1 followed by 28-day continuous dosing starting from Day 4. Four dosing regimens, 100mg b.i.d., 150 mg b.i.d., 125 mg t.i.d., and 200mg b.i.d. were studied. Pharmacokinetics (PK), safety, and efficacy of icotinib were evaluated. Icotinib was well tolerated in Chinese patients with refractory NSCLC. No toxicity with >3 grades were reported in more than 2 patients under any dose levels. One complete response (3%) and 9 partial responses (23%) were received. Total disease control rate could reach at 73% and median progress-free survival (range) was 154 (17-462) days. PK exposure of icotinib increased with increase of dose in NSCLC patients. Food was suggested to increase PK exposure by ∼30%. Mean t1/2β was within 5.31-8.07 h. No major metabolite (>10% plasma exposure of icotinib) was found in NSCLC patients. Icotinib with up to 400 mg/day exhibited good tolerance and preliminary antitumor activity in Chinese NSCLC patients. Pharmacokinetics of icotinib and 5 major metabolites were fully investigated in NSCLC patients. Optimized biologic dose (OBD) was finally recommended to be 125 mg t.i.d. for the later clinical study.

Minimizing forced outage risk in generator bidding

NASA Astrophysics Data System (ADS)

Das, Dibyendu

Competition in power markets has exposed the participating companies to physical and financial uncertainties. Generator companies bid to supply power in a day-ahead market. Once their bids are accepted by the ISO they are bound to supply power. A random outage after acceptance of bids forces a generator to buy power from the expensive real-time hourly spot market and sell to the ISO at the set day-ahead market clearing price, incurring losses. A risk management technique is developed to assess this financial risk associated with forced outages of generators and then minimize it. This work presents a risk assessment module which measures the financial risk of generators bidding in an open market for different bidding scenarios. The day-ahead power market auction is modeled using a Unit Commitment algorithm and a combination of Normal and Cauchy distributions generate the real time hourly spot market. Risk profiles are derived and VaRs are calculated at 98 percent confidence level as a measure of financial risk. Risk Profiles and VaRs help the generators to analyze the forced outage risk and different factors affecting it. The VaRs and the estimated total earning for different bidding scenarios are used to develop a risk minimization module. This module will develop a bidding strategy of the generator company such that its estimated total earning is maximized keeping the VaR below a tolerable limit. This general framework of a risk management technique for the generating companies bidding in competitive day-ahead market can also help them in decisions related to building new generators.

Developing cancer gene therapy constructs based on transcriptional targeting of genes to cancer cells is a new and promising modality for treatment of cancer. Introducing truncated Bid (tBid), a recently known member of the Bcl-2 family, eradicates cancer cells efficiently. For transcriptional targeting of tBid, two dual-specificity promoters, combining cancer specific core promoters and response modules, were designed. These two core promoter modules contained cancer specific promoters of MUC1 and Survivin genes accompanied by hypoxia-responsive elements and estrogen responsive elements (microenvironment condition of breast cancer cells) which were employed to achieve a higher and more specific level of tBid expression in breast cancer cells. Correlation of the level of tBid expression in normal and cancer cell lines with promoter activity was measured by RT-PCR after treatment with hypoxia and estrogen. The level of tBid expression under control of new hybrid promoters was compared with its expression under control of cytomegalovirus (CMV) promoter as a control. Our data revealed that the level of tBid expression in breast cancer cells were nearly 11 times more than normal cells because of the cancer specific promoters, although tBid expression under control of CMV promoter was almost the same in normal and cancer cell lines. Increased apoptosis was detected in the transfected breast cancer cell lines by the Caspase-3 activity assay. The application of these promoters may prove to have the advantage of tumor selective gene therapy in breast cancer cells and low-potential toxicity for normal tissues.

Significant partial response of metastatic intra-abdominal and pelvic round cell liposarcoma to a small-molecule VEGFR-2 tyrosine kinase inhibitor apatinib: A case report.

2016-08-01

Myxoid/round cell liposarcoma is the second most common subtype of liposarcoma. Chemotherapy and radiotherapy have a limited efficacy for treating advanced myxoid/round cell liposarcoma, with relatively serious side effects. We herein present a 68-year-old Chinese woman initially diagnosed with advanced multiple intra-abdominal and pelvic round cell liposarcoma.She refused to receive cytotoxic chemotherapy and received apatinib as the first-line therapy, a novel tyrosine kinase inhibitor of vascular endothelial growth factor receptor-2 that has been used in the treatment of patients with metastatic gastric cancer who progressed with 2 or more chemotherapy regimens. This patient was partially responsive to apatinib with a dose of 500 mg daily. No serious drug-related side effects were observed. Our findings indicate that some cases of liposarcoma may be responsive to antiangiogenic agent apatinib. Randomized clinical studies are needed to further confirm the efficacy and safety of apatinib in the clinical treatment of liposarcoma.

The effects of exenatide twice daily compared to insulin lispro added to basal insulin in Latin American patients with type 2 diabetes: A retrospective analysis of the 4B trial.

Socioeconomic changes in Latin American countries have led to an increased prevalence of type 2 diabetes (T2D). We examined the effects of exenatide twice daily (BID) or insulin lispro, each added to insulin glargine, in Latin American patients with T2D. This was a subgroup analysis of patients from Argentina and Mexico in the 4B study (N=114). Patients with glycated hemoglobin (HbA1c) of 7.0-10.0% (53-86mmol/mol) after 12weeks of intensive basal insulin optimization were randomized to exenatide BID or thrice-daily insulin lispro added to insulin glargine and metformin. After 30weeks, addition of exenatide BID or insulin lispro resulted in significant (P<0.0001) reductions in HbA1c (exenatide BID: -0.9% [-10mmol/mol]; insulin lispro: -1.2% [-13mmol/mol]). Weight was stable in the exenatide BID group (-0.1kg) and increased significantly (+3.4kg; P<0.0001) with insulin lispro. Major and minor hypoglycemia occurred less frequently (40 vs. 253 events) with exenatide BID compared with insulin lispro. Gastrointestinal adverse events of nausea, diarrhea, and vomiting occurred more frequently with exenatide BID than with insulin lispro. Both exenatide BID and prandial insulin lispro, each added to basal insulin glargine, were effective at reducing HbA1c in Latin American patients. Treatment with exenatide BID resulted in stable weight but more gastrointestinal adverse events. Treatment with insulin lispro resulted in weight gain and an increased risk of hypoglycemia. These findings support the addition of exenatide BID to insulin glargine as an option for Latin American patients unable to achieve glycemic control on basal insulin alone.

The most common malignancies of the female genital tract are endometrial carcinomas, whose are generally proceeded by hyperplasia. The maintenance of tissue homeostasis is to great extent governed by apoptosis, whose defects can lead to the preneoplastic and/or cancerous changes. Endometrial apoptosis involves among others three groups of proteins of the Bcl-2 family. First group contains anti-apoptotic proteins (e. g. Bcl-2, Bcl-xL). The other two groups belong to the pro-apoptotic proteins with three (e. g. Bax, Bak) or one (e. g. Bad, Bid) so-called BH domains. Bad and Bid trigger the oligomerization of Bak and Bax protein, which permeabilize the outer mitochondrial wall. Unlike Bid, Bad cannot directly trigger apoptosis. Instead, Bad lowers the threshold at which apoptosis is induced, by binding anti-apoptotic Bcl-2 proteins. However, their mutual counterbalance or synergism in the human endometrium has not been reported yet.In this study, the levels of Bid and Bad were measured using SDS-PAGE and Western blotting with specific antibodies, with the aim to analyse expression of Bid and Bad proteins in normal (NE), hyperplastic (HE) and cancerous (CE) endometrium. We demonstrated that Bid expression in CE reached only 47% and 50% of this observed in NE and HE. Conversely, Bad expression in HE reached only 40% and 36% of this observed in NE and CE, respectively. We detected no significant changes of Bid expression between HE and NE, and levels of Bad protein were not different between CE and NE.Trend of Bid and Bad protein expression is clearly opposite in HE and CE. We hypothesise that disrupted apoptotic program in CE seems to be reduced further by lowering levels of direct apoptotic trigger protein Bid. We suggest that the adenocarcinoma tissue of human endometrium thus tries to strengthen its apoptotic effort by lowering the apoptotic threshold via higher Bad levels.

[Body image dissatisfaction as a mediator of the association between BMI, self-esteem and mental health in early adolescents: a multiple-group path analysis across gender].

PubMed

Jang, Mi Heui; Lee, Gyungjoo

2013-04-01

This study was done to examine not only the relationships between body mass index (BMI), self-esteem, body image dissatisfaction (BID) and mental health, according to gender, but the mediating role of BID on mental health in relation to BMI and self-esteem among early adolescents. Data from 576 (296 boys and 280 girls) elementary school students in grades 5 to 6 were collected. A multiple-group path analysis was utilized to examine the relationships between BMI, self-esteem, BID and mental health by gender. In the path analysis for all students, poor mental health was related directly to BID, while it was indirectly related to BMI and self-esteem. In the multiple-group path analysis of both genders, BID was found to have a significant direct and indirect effect on mental health for girls alone. The findings suggested that BID should be examined early to prevent poor mental health in early adolescent girls. This study helps to elucidate the role of early adolescent BID on mental health and provides insight for further prevention and intervention programs in school and community mental health settings.

Switch from type II to I Fas/CD95 death signaling upon in vitro culturing of primary hepatocytes

Fas/CD95-induced apoptosis of hepatocytes in vivo proceeds through the so-called type II pathway, requiring the pro-apoptotic BH3-only Bcl-2 family member Bid for mitochondrial death signaling. Consequently, Bid-deficient mice are protected from anti-Fas antibody injection induced fatal hepatitis. Here we report the unexpected finding that freshly isolated mouse hepatocytes, cultured on collagen or Matrigel™, become independent of Bid for Fas-induced apoptosis, thereby switching death signaling from type II to type I. In such in vitro cultures, FasL activates caspase-3 without Bid cleavage, Bax/Bak activation or cytochrome c release, and neither Bid ablation nor Bcl-2 overexpression is protective. The type II to type I switch depends on extracellular matrix adhesion, as primary hepatocytes in suspension die in a Bid-dependent manner. Moreover, the switch is specific for FasL-induced apoptosis as collagen-plated Bid-deficient hepatocytes are protected from TNFα/ActD-induced apoptosis. Conclusion Our data suggest a selective crosstalk between extracellular matrix and Fas-mediated signaling which favours mitochondria-independent type I apoptosis induction. PMID:19003879

[Brain activitivation of euthymic patients with Type I bipolar disorder in resting state Default Mode Network].

PubMed

Vargas, Cristian; Pineda, Julián; Calvo, Víctor; López-Jaramillo, Carlos

2014-01-01

As there are still doubts about brain connectivity in type I bipolar disorder (BID), resting-state functional magnetic resonance imaging (RS-fMRI) studies are necessary during euthymia for a better control of confounding factors. To evaluate the differences in brain activation between euthymic BID patients and control subjects using resting state- functional-magnetic resonance imaging (RS-fMRI), and to identify the lithium effect in these activations. A cross-sectional study was conducted on 21 BID patients (10 receiving lithium only, and 11 non-medicated) and 12 healthy control subjects, using RS fMRI and independent component analysis (ICA). Increased activation was found in the right hippocampus (P=.049) and posterior cingulate (P=.040) within the Default Mode Network (DMN) when BID and control group were compared. No statistically significant differences were identified between BID on lithium only therapy and non-medicated BID patients. The results suggest that there are changes in brain activation and connectivity in BID even during euthymic phase and mainly within the DMN network, which could be relevant in affect regulation.

Tofacitinib is an oral, small-molecule Janus kinase inhibitor being investigated for ulcerative colitis (UC). In OCTAVE Induction 1 and 2, patients with moderately to severely active UC received placebo or tofacitinib 10 mg twice daily (BID) for 8 weeks. Clinical responders in OCTAVE Induction were re-randomized to 52 weeks' therapy with placebo, tofacitinib 5 mg BID, or tofacitinib 10 mg BID. We conducted post-hoc efficacy and safety analyses of East Asian patients in OCTAVE Induction 1 and 2 and OCTAVE Sustain. A total of 121 East Asian (Japan, Korea, and Taiwan) patients were randomized in OCTAVE Induction 1 and 2 (placebo, n=26; tofacitinib 10 mg BID, n=95), and 63 in OCTAVE Sustain (placebo, n=20; tofacitinib 5 mg BID, n=22; tofacitinib 10 mg BID, n=21). At week 8 of OCTAVE Induction 1 and 2, 18.9% of patients (18/95) achieved remission with tofacitinib 10 mg BID versus 3.8% (1/26) with placebo. In OCTAVE Sustain, the week 52 remission rates were 45.5% (10/22), 47.6% (10/21), and 15.0% (3/20) with 5 mg BID, 10 mg BID, and placebo, respectively. Adverse event rates were similar between groups in OCTAVE Induction and numerically higher with tofacitinib in OCTAVE Sustain. Serious adverse event rates were similar across groups in all studies. Infections were numerically more frequent with tofacitinib than placebo. Increases in serum lipid levels were observed with tofacitinib. In East Asian patients with UC, tofacitinib demonstrated numerically greater efficacy versus placebo as induction and maintenance therapy, with a safety profile consistent with the global study population.

Prior real-world studies have shown that apixaban is associated with a reduced risk of stroke/systemic embolism (stroke/SE) and major bleeding versus warfarin. However, few studies evaluated the effectiveness and safety of apixaban according to its dosage, and most studies contained limited numbers of patients prescribed 2.5 mg twice-daily (BID) apixaban. Using pooled data from 4 American claims database sources, baseline characteristics and outcomes for patients prescribed 5 mg BID and 2.5 mg BID apixaban versus warfarin were compared. After 1:1 propensity-score matching, 31,827 5 mg BID apixaban-matched warfarin patients and 6600 2.5 mg BID apixaban-matched warfarin patients were identified. Patients prescribed 2.5 mg BID apixaban were older, had clinically more severe comorbidities, and were more likely to have a history of stroke and bleeding compared with 5 mg BID apixaban patients. Compared with warfarin, 5 mg BID apixaban was associated with a lower risk of stroke/SE (hazard ratio [HR]: 0.70, 95% confidence interval [CI]: 0.60-0.81) and major bleeding (HR: 0.59, 95% CI: 0.53-0.66). Compared with warfarin, 2.5 mg BID apixaban was also associated with a lower risk of stroke/SE (HR: 0.63, 95% CI: 0.49-0.81) and major bleeding (HR: 0.59, 95% CI: 0.49-0.71). In this real-world study, both apixaban doses were assessed in 2 patient groups differing in age and clinical characteristics. Each apixaban dose was associated with a lower risk of stroke/SE and major bleeding compared with warfarin in the distinct population for which it is being prescribed in United States clinical practice.

Rationality, irrationality and escalating behavior in lowest unique bid auctions.

Radicchi, Filippo; Baronchelli, Andrea; Amaral, Luís A N

2012-01-01

Information technology has revolutionized the traditional structure of markets. The removal of geographical and time constraints has fostered the growth of online auction markets, which now include millions of economic agents worldwide and annual transaction volumes in the billions of dollars. Here, we analyze bid histories of a little studied type of online auctions--lowest unique bid auctions. Similarly to what has been reported for foraging animals searching for scarce food, we find that agents adopt Lévy flight search strategies in their exploration of "bid space". The Lévy regime, which is characterized by a power-law decaying probability distribution of step lengths, holds over nearly three orders of magnitude. We develop a quantitative model for lowest unique bid online auctions that reveals that agents use nearly optimal bidding strategies. However, agents participating in these auctions do not optimize their financial gain. Indeed, as long as there are many auction participants, a rational profit optimizing agent would choose not to participate in these auction markets.

Issues in bidding for contracts for occupational therapy services.

PubMed

Harms, S; Law, M

2001-06-01

There is an increasing number of occupational therapists in Canada who are involved in bidding for contracts to deliver occupational therapy services. Occupational therapists working in an institutional or community-based setting may not have had the responsibility of developing a proposal or a marketing plan for bidding purposes. However, the responsibility of developing a bid to compete for a service delivery contract often rests on occupational therapists who are sole practitioners in a private practice setting. The purpose of this paper is to highlight issues in the literature such as service delivery plans, marketing strategies and costing of services that can assist the occupational therapist in the development of a contractual bid. A specific clinical example, school therapy services, has been used to illustrate how these strategies can be applied to practice. Success in contractual bids appears to be primarily influenced by cost of the service, the expertise of the service provider, ability to provide coordinated care, ease of access for clients, and inclusion of methods to measure client outcome.

This study evaluated the effect of lorcaserin 10 mg twice daily (LOR BID), or with phentermine 15 mg once daily (LOR BID + PHEN QD) and 15 mg twice daily (LOR BID + PHEN BID), in conjunction with energy restriction on food cravings. Two hundred and thirty-five patients without diabetes but with obesity or overweight and ≥ 1 comorbidity received LOR BID, LOR BID + PHEN QD, or LOR BID + PHEN BID for 12 weeks in a randomized double-blind study. The Food Craving Inventory (FCI) and the Control of Eating Questionnaire (COEQ) were administered over 12 weeks. The FCI total score and the subscale scores reduced from baseline in all groups. The least squares means (95% confidence intervals) for the total scores were -0.65 (-0.75 to -0.55), -0.75 (-0.84 to -0.65), and -0.84 (-0.95 to -0.74) in the LOR BID, LOR BID + PHEN QD, and LOR BID + PHEN BID groups, respectively. Cravings assessed by COEQ reduced from baseline in all groups. In general, the combination treatments were more effective than lorcaserin alone. At week 12, except for fruit juice and dairy products, general and specific cravings reduced in LOR BID + PHEN BID compared with LOR BID (P < 0.05). Lorcaserin in combination with phentermine improves control of food cravings during short-term energy restriction. © 2018 The Obesity Society.

Evaluation of a novel helium ionization detector within the context of (low-)flow modulation comprehensive two-dimensional gas chromatography.

The present research is focused on the use and evaluation of a novel helium ionization detector, defined as barrier discharge ionization detector (BID), within the context of (low-)flow modulation comprehensive two-dimensional gas chromatography (FM GC×GC). The performance of the BID device was compared to that of a flame ionization detector (FID), under similar FM GC×GC conditions. Following development and optimization of the FM GC×GC method, the BID was subjected to fine tuning in relation to acquisition frequency and discharge flow. Moreover, the BID performance was measured and compared to that of the FID, in terms of extra-column band broadening, sensitivity and dynamic range. The comparative study was carried out by using standard compounds belonging to different chemical classes, along with a sample of diesel fuel. Advantages and disadvantages of the BID system, also within the context of FM GC×GC, are critically discussed. In general, the BID system was characterized by a more limited dynamic range and increased sensitivity, compared to the FID. Additionally, BID and FID contribution to band broadening was found to be similar under the operational conditions applied. Particular attention was devoted to the behaviour of the FM GC×GC-BID system toward saturated and aromatic hydrocarbons, for a possible future use in the field of mineral-oil food contamination research.

Competition in the economic crisis: Analysis of procurement auctions.

PubMed

Gugler, Klaus; Weichselbaumer, Michael; Zulehner, Christine

2015-01-01

We study the effects of the recent economic crisis on firms׳ bidding behavior and markups in sealed bid auctions. Using data from Austrian construction procurements, we estimate bidders׳ construction costs within a private value auction model. We find that markups of all bids submitted decrease by 1.5 percentage points in the recent economic crisis, markups of winning bids decrease by 3.3 percentage points. We also find that without the government stimulus package this decrease would have been larger. These two pieces of evidence point to pro-cyclical markups.

Competitive bidding for home care under the channeling demonstration

Christianson, Jon B.

1987-01-01

Competitive bidding is a relatively new strategy for setting rates and choosing providers for public medical care programs. In this article, the experience in competitive bidding by home health care providers and homemaker agencies in the National Long-Term Care Channeling Demonstration is described. Particular attention is paid to contrasting approaches that select a single winning bidder with those that select multiple winning bidders for the same service. Results are discussed with respect to bid prices, characteristics of winning bidders, administrative demands, and service delivery. PMID:10312190

AIM: To compare the effectiveness of standard triple, bismuth pectin quadruple and sequential therapies for Helicobacter pylori (H. pylori) eradication in a randomized, double-blinded, comparative clinical trial in China. METHODS: A total of 215 H. pylori-positive patients were enrolled in the study and randomly allocated into three groups: group A (n = 72) received a 10-d bismuth pectin quadruple therapy (20 mg rabeprazole bid, 1000 mg amoxicillin bid, 100 mg bismuth pectin qid, and 500 mg levofloxacin qd); group B (n = 72) received the sequential therapy (20 mg omeprazole bid, 1000 mg amoxicillin bid, in 5 d, followed by 20 mg omeprazole bid, 500 mg tinidazole bid, 500 mg clarithromycin bid, for another 5 d); group C (n = 71) received a standard 1-wk triple therapy (20 mg omeprazole bid, 1000 mg amoxicillin bid, 500 mg clarithromycin bid). After all these treatments, 20 mg omeprazole bid was administrated for 3 wk. H. pylori status was assessed by histology, 13C-urea breath test and rapid urease test at baseline and 4-6 wk after completion of treatment. Ulcer cicatrization was assessed by gastroscopy. χ2 test (P < 0.05) was used to compare the eradication rates and ulcer cicatrisation rates among the three groups. RESULTS: The eradication rate was 83.33% (60/72) in group A, 88.89% (64/72) in group B, and 80.56% (58/71) in group C. The ulcer cicatrisation rate was 86.44% (51/59) in group A, 90.16% (55/61) in group B, and 84.91% (45/53) in group C. The sequential therapy yielded a higher eradication rate and ulcer cicatrisation rate than the standard triple and bismuth pectin quadruple therapies. Statistically, the eradication rate of group B was significantly different from groups A and C (P < 0.05), but the difference of ulcer cicatrisation rate and side effects was not statistically significant among the three groups (P > 0.05). The three protocols were generally well tolerated. CONCLUSION: The sequential therapy has achieved a significantly higher eradication rate, and is a more suitable first-line alternative protocol for anti-H. pylori infection compared with the standard triple and bismuth pectin quadruple therapies.

Sequential steps in DNA replication are inhibited to ensure reduction of ploidy in meiosis

Meiosis involves two successive rounds of chromosome segregation without an intervening S phase. Exit from meiosis I is distinct from mitotic exit, in that replication origins are not licensed by Mcm2-7 chromatin binding, but spindle disassembly occurs during a transient interphase-like state before meiosis II. The absence of licensing is assumed to explain the block to DNA replication, but this has not been formally tested. Here we attempt to subvert this block by expressing the licensing control factors Cdc18 and Cdt1 during the interval between meiotic nuclear divisions. Surprisingly, this leads only to a partial round of DNA replication, even when these factors are overexpressed and effect clear Mcm2-7 chromatin binding. Combining Cdc18 and Cdt1 expression with modulation of cyclin-dependent kinase activity, activation of Dbf4-dependent kinase, or deletion of the Spd1 inhibitor of ribonucleotide reductase has little additional effect on the extent of DNA replication. Single-molecule analysis indicates this partial round of replication results from inefficient progression of replication forks, and thus both initiation and elongation replication steps may be inhibited in late meiosis. In addition, DNA replication or damage during the meiosis I–II interval fails to arrest meiotic progress, suggesting absence of checkpoint regulation of meiosis II entry. PMID:23303250

Cytotoxicity of diacetoxyscirpenol is associated with apoptosis by activation of caspase-8 and interruption of cell cycle progression by down-regulation of cdk4 and cyclin B1 in human Jurkat T cells

2007-07-15

To understand the mechanism underlying T-cell toxicity of diacetoxyscirpenol (DAS) from Fusarium sambucinum, its apoptogenic as well as growth retardation activity was investigated in human Jurkat T cells. Exposure to DAS (0.01-0.15 {mu}M) caused apoptotic DNA fragmentation along with caspase-8 activation, Bid cleavage, mitochondrial cytochrome c release, activation of caspase-9 and caspase-3, and PARP degradation, without any alteration in the levels of Fas or FasL. Under these conditions, necrosis was not accompanied. The cytotoxicity of DAS was not blocked by the anti-Fas neutralizing antibody ZB-4. Although the DAS-induced apoptotic events were completely prevented by overexpression of Bcl-xL, the cells overexpressingmore » Bcl-xL were unable to divide in the presence of DAS, resulting from the failure of cell cycle progression possibly due to down-regulation in the protein levels of cdk4 and cyclin B1. The DAS-mediated apoptosis and activation of caspase-8, -9, and -3 were abrogated by either pan-caspase inhibitor (z-VAD-fmk) or caspase-8 inhibitor (z-IETD-fmk). While the DAS-mediated apoptosis and activation of caspase-9 and caspase-3 were slightly suppressed by the mitochondrial permeability transition pore inhibitor (CsA), both caspase-8 activation and Bid cleavage were not affected by CsA. The activated normal peripheral T cells possessed a similar susceptibility to the cytotoxicity of DAS. These results demonstrate that the T-cell toxicity of DAS is attributable to not only apoptosis initiated by caspase-8 activation and subsequent mitochondrion-dependent or -independent activation of caspase cascades, which can be regulated by Bcl-xL, but also interruption of cell cycle progression caused by down-regulation of cdk4 and cyclin B1 proteins.« less

Axitinib, an antiangiogenic multikinase inhibitor (MKI), was evaluated in the compassionate use programme (CUP) in Spain (October 2012-November 2014). 47 patients with advanced radioactive iodine (RAI)-refractory differentiated thyroid cancer (DTC, n  = 34) or medullary thyroid cancer (MTC, n  = 13) with documented disease progression were treated with axitinib 5 mg b.i.d. The primary efficacy endpoint was objective response rate (ORR) by Response Evaluation Criteria In Solid Tumors (RECIST) v1.1. Progression-free survival (PFS) and adverse events (AEs) were secondary objectives. Regulatory authorities validated the CUP, and all patients signed informed consent form. Axitinib was administered as first-line therapy in 17 patients (36.2%), as second-line in 18 patients (38.3%) and as third/fourth-line in 12 patients (25.5%). With a median follow-up of 11.5 months (0-24.3), ORR was 27.7% (DTC: 29.4% and MTC: 23.1%) and median PFS was 8.1 months (95% CI: 4.1-12.2) (DTC: 7.4 months (95% CI: 3.1-11.8) and MTC: 9.4 months (95% CI: 4.8-13.9)). Better outcomes were reported with first-line axitinib, with an ORR of 53% and a median PFS of 13.6 months compared with 16.7% and 10.6 months as second-line treatment. Twelve (25.5%) patients required dose reduction to 3 mg b.i.d. All-grade AEs included asthenia (53.2%), diarrhoea (36.2%), hypertension (31.9%) and mucositis (29.8%); grade 3/4 AEs included anorexia (6.4%), diarrhoea (4.3%) and cardiac toxicity (4.3%). Axitinib had a tolerable safety profile and clinically meaningful activity in refractory and progressive thyroid cancer regardless of histology as first-line therapy. To our knowledge, this is the first time that cross-resistance between MKIs is suggested in thyroid cancer, highlighting the importance of prospective sequential clinical studies. © 2017 European Society of Endocrinology.

Influence of successive badminton matches on muscle strength, power, and body-fluid balance in elite players.

The aim was to analyze the influence of competitive round on muscle strength, body-fluid balance, and renal function in elite badminton players during a real competition. Body mass, jump height during a countermovement jump, handgrip force, and urine samples were obtained from 13 elite badminton players (6 men and 7 women) before and after the 2nd-round and quarterfinal matches of the national Spanish badminton championship. Sweat rate was determined by using prematch-to-postmatch body-mass change and by weighing individually labeled fluid bottles. Sweat rates were 1.04 ± 0.62 and 0.98 ± 0.43 L/h, while rehydration rate was 0.69 ± 0.26 and 0.91 ± 0.52 L/h for the 2nd round and quarterfinals, respectively. Thus, dehydration was 0.47% ± 1.03% after the 2nd round and 0.23% ± 0.43% after the quarterfinals. There were no differences in prematch-to-postmatch jump height, but jump height was reduced from 37.51 ± 8.83 cm after the 2nd-round game to 34.82 ± 7.37 cm after the quarterfinals (P < .05). No significant differences were found in handgrip force when comparing prepost matches or rounds, although there were significant differences between dominant and nondominant hands (P < .05). The succession of rounds caused the appearance of proteinuria, hematuria, glycosuria, and higher nitrite and ketone concentrations in urine. Rehydration patterns during a real badminton competition were effective to prevent dehydration. A badminton match did not affect jump height or handgrip force, but jump height was progressively reduced by the competitive round. Badminton players' renal responses reflected diminished renal flux due to the high-intensity nature of this racket sport.

To assess the efficacy and safety of a new repaglinide/metformin fixed-dose combination (FDC) tablet administered either twice a day (BID) or three times a day (TID) for the management of type 2 diabetes. This was a 26-week, multicentre, open-label parallel trial in which subjects poorly controlled with mono- or dual-oral antidiabetic therapy were randomized 1 : 1 : 1 to instead receive repaglinide/metformin FDC either BID or TID or a rosiglitazone/metformin FDC BID. Two primary hypotheses were tested in a hierarchical manner: (i) treatment with the repaglinide/metformin FDC BID is non-inferior to that of the rosiglitazone/metformin FDC BID as measured by changes in haemoglobin A1c (HbA1c) (results presented in companion paper) and (ii) repaglinide/metformin BID is non-inferior to repaglinide/metformin TID (as measured by changes in HbA1c). Additional efficacy and safety end-points were also assessed. A total of 561 subjects were randomized; 383 completed the study. Repaglinide/metformin FDC BID was non-inferior to repaglinide/metformin FDC TID with respect to HbA1c. Additionally, changes in mean fasting plasma glucose values from baseline to end of study were not significantly different between the BID and the TID dose groups. There were no major hypoglycaemic episodes reported in either group during the trial, and overall adverse event profiles were similar. The efficacy of twice-daily dosing of a repaglinide/metformin FDC tablet was non-inferior to that of three-times-daily dosing.

Susceptibility of Hep3B cells in different phases of cell cycle to tBid.

tBid is a pro-apoptotic molecule. Apoptosis inducers usually act in a cell cycle-specific fashion. The aim of this study was to elucidate whether effect of tBid on hepatocellular carcinoma (HCC) Hep3B cells was cell cycle phase specific. We synchronized Hep3B cells at G0/G1, S or G2/M phases by chemicals or flow sorting and tested the susceptibility of the cells to recombinant tBid. Cell viability was measured by MTT assay and apoptosis by TUNEL. The results revealed that tBid primarily targeted the cells at G0/G1 phase of cell cycle, and it also increased the cells at the G2/M phase. 5-Fluorouracil (5-FU), on the other hand, arrested Hep3B cells at the G0/G1 phase, but significantly reduced cells at G2/M phase. The levels of cell cycle-related proteins and caspases were altered in line with the change in the cell cycle. The combination of tBid with 5-FU caused more cells to be apoptotic than either agent alone. Therefore, the complementary effect of tBid and 5-FU on different phases of the cell cycle may explain their synergistric effect on Hep3B cells. The elucidation of the phase-specific effect of tBid points to a possible therapeutic option that combines different phase specific agents to overcome resistance of HCC.

Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). This post hoc analysis investigated the effect of methotrexate (MTX) dose on the efficacy of tofacitinib in patients with RA. ORAL Scan (NCT00847613) was a 2-year, randomized, Phase 3 trial evaluating tofacitinib in MTX-inadequate responder (IR) patients with RA. Patients received tofacitinib 5 or 10 mg twice daily (BID), or placebo, with low (≤12.5 mg/week), moderate (>12.5 to <17.5 mg/week), or high (≥17.5 mg/week) stable background MTX. Efficacy endpoints (at months 3 and 6) included American College of Rheumatology (ACR) 20/50/70 response rates, and mean change from baseline in Clinical Disease Activity Index (CDAI), Disease Activity Score in 28 joints (DAS28)-4(erythrocyte sedimentation rate [ESR]), Health Assessment Questionnaire-Disability Index (HAQ-DI), and modified Total Sharp score. 797 patients were treated with tofacitinib 5 mg BID (N = 321), tofacitinib 10 mg BID (N = 316), or placebo (N = 160); 242, 333, and 222 patients received low, moderate, and high MTX doses, respectively. At months 3 and 6, ACR20/50/70 response rates were greater for both tofacitinib doses vs placebo across all MTX doses. At month 3, mean changes from baseline in CDAI and HAQ-DI were significantly greater for both tofacitinib doses vs placebo, irrespective of MTX category; improvements were maintained at month 6. Both tofacitinib doses demonstrated improvements in DAS28-4(ESR), and less structural progression vs placebo, across MTX doses at month 6. Tofacitinib plus MTX showed greater clinical and radiographic efficacy than placebo in MTX-IR patients with RA, regardless of MTX dose.

Sorafenib in advanced melanoma: a critical role for pharmacokinetics?

Background: Inter-patient pharmacokinetic variability can lead to suboptimal drug exposure, and therefore might impact the efficacy of sorafenib. This study reports long-term pharmacokinetic monitoring of patients treated with sorafenib and a retrospective pharmacodynamic/pharmacokinetic analysis in melanoma patients. Patients and methods: Heavily pretreated patients with stage IV melanoma were started on sorafenib 400 mg twice daily (bid). In the absence of limiting toxicity, dose escalation of 200 mg bid levels was done every 2 weeks. Plasma sorafenib measurement was performed at each visit, allowing a retrospective pharmacodynamic/pharmacokinetic analysis for safety and efficacy. Results: In all, 19 of 30 patients underwent dose escalation over 400 mg bid, and 28 were evaluable for response. The overall disease control rate was 61% (95% confidence interval (CI): 42.6–78.8), including three confirmed responses (12%). Disease control rate and progression-free survival (PFS) were improved in patients with high vs low exposure (80% vs 32%, P=0.02, and 5.25 vs 2.5 months, P=0.005, hazard ratio (HR)=0.28 (95% CI: 0.11–0.73)). In contrast, drug dosing had no effect on PFS. In multivariate analysis, drug exposure was the only factor associated with PFS (HR=0.36 (95% CI: 0.13–0.99)). Diarrhoea and anorexia were correlated with drug dosing, while hypertension and hand–foot skin reaction were correlated with drug exposure. Conclusions: Although sorafenib had modest efficacy in melanoma, these results suggest a correlation between exposure and efficacy of sorafenib. Therefore, dose optimisation in patients with low exposure at standard doses should be evaluated in validated indications. PMID:22767146

Arrhythmias in horses may require long-term anti-arrhythmic therapy. Unfortunately, oral anti-arrhythmic drugs for use in horses are currently scarce. In human patients and small animals, sotalol, a β-blocker with class III anti-arrhythmic properties, is often used for long-term treatment. To determine the pharmacokinetics of sotalol at multiple oral dosages in unfasted horses, as well as the effects on electro- and echocardiographic measurements, right atrial and ventricular monophasic action potential (MAP) and effective refractory period (ERP). Placebo controlled, double-blinded experiment. Six healthy, unfasted Warmblood horses were given either 0, 2, 3 or 4 mg/kg bodyweight (bwt) sotalol orally (PO) twice daily (bid) for 9 days in a randomised cross-over design. Echocardiography and surface electrocardiography were performed and plasma concentrations of sotalol and right atrial and right ventricular MAPs and ERPs were determined at steady-state conditions. Statistical analysis was performed using a repeated measures univariate analysis with post hoc Bonferroni corrections. Calculated mean steady-state plasma concentrations determined by nonlinear mixed-effect modelling were 287 (range 234-339), 409 (359-458) and 543 (439-646) ng/mL for 2, 3 and 4 mg/kg bwt sotalol PO bid respectively. Sotalol significantly increased the QT interval and ERPs, but, despite increasing plasma concentrations, higher dosages did not result in a progressive increase in QT interval or ERPs. Echocardiographic and other electrocardiographic measurements did not change significantly. MAP durations at 90% repolarisation were not significantly different during sotalol treatment. Besides transient local sweating, no side effects were noted. Study size and ad libitum feeding of hay. Sotalol at a dose of 2, 3 and 4 mg/kg bwt PO bid increases the QT interval and ERP and might be a useful drug for long-term anti-arrhythmic therapy in horses. © 2017 EVJ Ltd.

Mithramycin A (Mith) is an aureolic acid-type polyketide produced by various soil bacteria of the genus Streptomyces. Mith inhibits myeloid cell leukemia-1 (Mcl-1) to induce apoptosis in prostate cancer, but the molecular mechanism underlying this process has not been fully elucidated. The aim of this study was therefore to investigate the detailed molecular mechanism related to Mith-induced apoptosis in prostate cancer cells. Mith decreased the phosphorylation of mammalian target of rapamycin (mTOR) in both cell lines overexpressing phospho-mTOR compared to RWPE-1 human normal prostate epithelial cells. Mith significantly induced truncated Bid (tBid) and siRNA-mediated knock-down of Mcl-1 increased tBid protein levels. Moreover, Mith also inhibited the phosphorylation of mTOR on serine 2448 and Mcl-1, and increased tBid protein in prostate tumors in athymic nude mice bearing DU145 cells as xenografts. Thus, Mith acts as an effective tumor growth inhibitor in prostate cancer cells through the mTOR/Mcl-1/tBid signaling pathway. PMID:24062605

We report a phase 1 study to examine the safety and recommended dose of the oral protein kinase C-beta inhibitor (anti-angiogenic) enzastaurin in combination with single-agent temozolomide. The study was conducted in patients with recurrent glioblastoma or newly diagnosed disease that was not treatable with standard (chemo)radiotherapy. Patients were treated with standard dose temozolomide (200 mg/m2 for 5 days every 4 weeks) together with daily oral enzastaurin. Three dose levels of enzastaurin were investigated: 250 mg daily (OD), 500 mg OD, and 250 mg twice daily (BID). Dose-limiting toxicity was determined in the first 2 cycles, but treatment continued until limiting toxicity or disease progression was identified. Twenty-eight patients were enrolled. No dose-limiting toxicity was noted at 250 mg OD or 500 mg OD. However, at 250 mg BID, 2 dose-limiting episodes of thrombocytopenia were noted. The recommended dose for enzastaurin in combination with standard 4-weekly temozolomide is therefore 500 mg OD. The pharmacokinetics of enzastaurin in combination with temozolomide was evaluated. Temozolomide did not appear to effect enzastaurin exposures at the 250 mg or 500 mg OD dose levels. PMID:22291006

Prior real-world studies have shown that apixaban is associated with a reduced risk of stroke/systemic embolism (stroke/SE) and major bleeding versus warfarin. However, few studies evaluated the effectiveness and safety of apixaban according to its dosage, and most studies contained limited numbers of patients prescribed 2.5 mg twice-daily (BID) apixaban. Using pooled data from 4 American claims database sources, baseline characteristics and outcomes for patients prescribed 5 mg BID and 2.5 mg BID apixaban versus warfarin were compared. After 1:1 propensity-score matching, 31,827 5 mg BID apixaban-matched warfarin patients and 6600 2.5 mg BID apixaban-matched warfarin patients were identified. Patients prescribed 2.5 mg BID apixaban were older, had clinically more severe comorbidities, and were more likely to have a history of stroke and bleeding compared with 5 mg BID apixaban patients. Compared with warfarin, 5 mg BID apixaban was associated with a lower risk of stroke/SE (hazard ratio [HR]: 0.70, 95% confidence interval [CI]: 0.60–0.81) and major bleeding (HR: 0.59, 95% CI: 0.53–0.66). Compared with warfarin, 2.5 mg BID apixaban was also associated with a lower risk of stroke/SE (HR: 0.63, 95% CI: 0.49–0.81) and major bleeding (HR: 0.59, 95% CI: 0.49–0.71). In this real-world study, both apixaban doses were assessed in 2 patient groups differing in age and clinical characteristics. Each apixaban dose was associated with a lower risk of stroke/SE and major bleeding compared with warfarin in the distinct population for which it is being prescribed in United States clinical practice.

Objective: Huperzine A is a natural cholinesterase inhibitor derived from the Chinese herb Huperzia serrata that may compare favorably in symptomatic efficacy to cholinesterase inhibitors currently in use for Alzheimer disease (AD). Methods: We assessed the safety, tolerability, and efficacy of huperzine A in mild to moderate AD in a multicenter trial in which 210 individuals were randomized to receive placebo (n = 70) or huperzine A (200 μg BID [n = 70] or 400 μg BID [n = 70]), for at least 16 weeks, with 177 subjects completing the treatment phase. The primary analysis assessed the cognitive effects of huperzine A 200 μg BID (change in Alzheimer's Disease Assessment Scale–cognitive subscale [ADAS-Cog] at week 16 at 200 μg BID compared to placebo). Secondary analyses assessed the effect of huperzine A 400 μg BID, as well as effect on other outcomes including Mini-Mental State Examination, Alzheimer's Disease Cooperative Study–Clinical Global Impression of Change scale, Alzheimer's Disease Cooperative Study Activities of Daily Living scale, and Neuropsychiatric Inventory (NPI). Results: Huperzine A 200 μg BID did not influence change in ADAS-Cog at 16 weeks. In secondary analyses, huperzine A 400 μg BID showed a 2.27-point improvement in ADAS-Cog at 11 weeks vs 0.29-point decline in the placebo group (p = 0.001), and a 1.92-point improvement vs 0.34-point improvement in the placebo arm (p = 0.07) at week 16. Changes in clinical global impression of change, NPI, and activities of daily living were not significant at either dose. Conclusion: The primary efficacy analysis did not show cognitive benefit with huperzine A 200 μg BID. Classification of evidence: This study provides Class III evidence that huperzine A 200 μg BID has no demonstrable cognitive effect in patients with mild to moderate AD. PMID:21502597

Evaluate the efficacy and safety of asenapine 2.5 mg twice daily (bid; n=97) or 5 mg bid (n=113) versus placebo (n=101) in adults with acute exacerbation of schizophrenia. Adults with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) schizophrenia diagnosis were randomized to asenapine 2.5 mg bid, 5 mg bid, placebo, or olanzapine 15 mg once daily. The primary objective was to test superiority of asenapine versus placebo as measured by the change from baseline to day 42 in the Positive and Negative Syndrome Scale (PANSS) total score. The key safety objective was to evaluate weight change in asenapine versus olanzapine at day 42. The primary efficacy endpoint was met; the difference in least squares mean change from baseline to day 42 in PANSS total score between asenapine 5 mg bid and placebo was -5.5 points (unadjusted 95% CI: -10.1, -1.0; multiplicity adjusted P=0.0356). Neither asenapine 2.5 mg bid nor olanzapine 15mg were superior to placebo. Both asenapine groups demonstrated significantly less weight gain than olanzapine at day 42. Significantly higher incidences of oral hypoesthesia and dysgeusia (combined) for asenapine 2.5 mg bid (5.2% vs 0.0%; P=0.0217) and 5 mg bid (7.1% vs 0.0%; P=0.0033) were observed versus placebo. There were no significant differences between asenapine and placebo for insomnia, extrapyramidal symptoms, akathisia, dizziness, or combination of somnolence/sedation/hypersomnia. This study supports previous efficacy and safety findings of asenapine; asenapine 5 mg bid is the lowest effective dose in adults with schizophrenia. Asenapine was associated with significantly less weight gain than olanzapine at day 42.

Imepitoin was tested as a combination treatment with phenobarbital in an open-label mono-centre cohort study in dogs with drug-resistant epilepsy. Diagnosis of idiopathic epilepsy was based on clinical findings, magnetic resonance imaging and cerebrospinal fluid analysis. Three cohorts were treated. In cohort A, dogs not responding to phenobarbital with or without established add-on treatment of potassium bromide or levetiracetam were treated add-on with imepitoin, starting at 10 mg/kg BID, with titration allowed to 30 mg/kg BID. In cohort B, the only difference to cohort A was that the starting dose of imepitoin was reduced to 5 mg/kg BID. In cohort C, animals not responding to imepitoin at >20 mg/kg BID were treated with phenobarbital add-on starting at 0.5 mg/kg BID. The add-on treatment resulted in a reduction in monthly seizure frequency (MSF) in all three cohorts. A reduction of ≥50% was obtained in 36-42% of all animals, without significant difference between cohorts. The lower starting dose of 5 mg/kg BID imepitoin was better tolerated, and an up-titration to on average of 15 mg/kg BID was sufficient in cohort A and B. In cohort C, a mean add-on dose of 1.5 mg/kg BID phenobarbital was sufficient to achieve a clinically meaningful effect. Six dogs developed a clinically meaningful increase in MSF of ≥ 50%, mostly in cohort A. Neither imepitoin nor phenobarbital add-on treatment was capable of suppressing cluster seizure activity, making cluster seizure activity an important predictor for drug-resistance. A combination treatment of imepitoin and phenobarbital is a useful treatment option for a subpopulation of dogs with drug-resistant epilepsy, a low starting dose with 5 mg/kg BID is recommended.

Making the decision to participate in the tender is subject to a number of factors, affects the health of the company and is an important aspect in its quest for success. Efforts to select bidding factors have been repeatedly undertaken in various countries and in numerous construction markets. Researchers usually give a long list of factors, also called criteria, which in their opinion may significantly influence the bidding decision. The paper presents an attempt to reduce a proposed set of bidding factorsdefined in Poland with the use of thePrincipal Component Analysis.

The power market trading technical analysis refers to a method that takes the bidding behavior of members in the power market as the research object, sums up some typical market rules and price trends by applying mathematical and logical methods, and finally can effectively assist members in the power market to make more reasonable trading decisions. In this paper, the following four indicators have been proposed: bidding price difference scale, extreme bidding price rate, dispersion of bidding price and monthly transaction satisfaction of electricity trading, which are the core of the index system.

Loss of BID Delays FASL-Induced Cell Death of Mouse Neutrophils and Aggravates DSS-Induced Weight Loss.

Neutrophils are key players in the early defense against invading pathogens. Due to their potent effector functions, programmed cell death of activated neutrophils has to be tightly controlled; however, its underlying mechanisms remain unclear. Fas ligand (FASL/CD95L) has been shown to induce neutrophil apoptosis, which is accelerated by the processing of the BH3-only protein BH3 interacting domain death agonist (BID) to trigger mitochondrial apoptotic events, and been attributed a regulatory role during viral and bacterial infections. Here, we show that, in accordance with previous works, mouse neutrophils underwent caspase-dependent apoptosis in response to FASL, and that this cell death was significantly delayed upon loss of BID. However, pan-caspase inhibition failed to protect mouse neutrophils from FASL-induced apoptosis and caused a switch to RIPK3-dependent necroptotic cell death. Intriguingly, such a switch was less evident in the absence of BID, particularly under inflammatory conditions. Delayed neutrophil apoptosis has been implicated in several auto-inflammatory diseases, including inflammatory bowel disease. We show that neutrophil and macrophage driven acute dextran sulfate sodium (DSS) induced colitis was slightly more aggravated in BID-deficient mice, based on significantly increased weight loss compared to wild-type controls. Taken together, our data support a central role for FASL > FAS and BID in mouse neutrophil cell death and further underline the anti-inflammatory role of BID.

Some reference opioids containing the Dmt-Tic pharmacophore, especially the delta agonists H-Dmt-Tic-Gly-NH-Ph (1) and H-Dmt-Tic-NH-(S)CH(CH2-COOH)-Bid (4) (UFP-512) were evaluated for the influence of the substitution of Gly with aspartic acid, its chirality, and the importance of the -NH-Ph and N(1)H-Bid hydrogens in the inductions of delta agonism. The results provide the following conclusions: (i) Asp increases delta selectivity by lowering the mu affinity; (ii) -NH-Ph and N(1)H-Bid nitrogens methylation transforms the delta agonists into delta antagonists; (iii) the substitution of Gly with L-Asp/D-Asp in the delta agonist H-Dmt-Tic-Gly-NH-Ph gave delta antagonists; the same substitution in the delta agonist H-Dmt-Tic-NH-CH2-Bid yielded more selective agonists, H-Dmt-Tic-NH-(S)CH(CH2-COOH)-Bid and H-Dmt-Tic-NH-(R)CH(CH2-COOH)-Bid; (iv) L-Asp seems important only in functional bioactivity, not in receptor affinity; (v) H-Dmt-Tic-NH-(S)CH(CH2-COOH)-Bid(N(1)-Me) (10) evidenced analgesia similar to 4, which was reversed by naltrindole only in the tail flick. 4 and 10 had opposite behaviours in mice; 4 caused agitation, 10 gave sedation and convulsions.

Minority business bidding for local government contracts: the complexity of availability.

PubMed

Bangs, Ralph L; Murrell, Audrey; Constance-Huggins, Monique

2007-01-01

While minority-business enterprises (MBEs) have gained some access to local government contracts during the last three decades, these firms continue to receive a small share of local government contract spending relative to the number of available firms. Researchers have suggested two general explanations for the low representation of MBEs in contract awards: (1) lack of qualifications and capacity among MBEs, and (2) public and private discrimination against MBEs in contracting processes. This study on prime contract opportunities in a Northern central city and county with a large minority population finds that low bid rates greatly contribute to the low MBE shares of prime contracts and that bidding is reduced by both local government processes and characteristics of the firms. Some implications of these findings are that local governments need to: (1) monitor MBE shares of prime contract bids by size of contract and use share of bids as one measure of program and organizational effectiveness; (2) identify MBEs that are qualified for prime contracts and encourage and help interested firms to submit competitive bids; and (3) ensure that local government policies and practices do not diminish access to information about prime contract opportunities for qualified and interested minority firms. Another implication is that bidders lists should not be a primary basis for determining MBE availability, since many qualified and interested MBEs do not bid because of perceived barriers in local government.

Significant partial response of metastatic intra-abdominal and pelvic round cell liposarcoma to a small-molecule VEGFR-2 tyrosine kinase inhibitor apatinib

Abstract Introduction: Myxoid/round cell liposarcoma is the second most common subtype of liposarcoma. Chemotherapy and radiotherapy have a limited efficacy for treating advanced myxoid/round cell liposarcoma, with relatively serious side effects. Case presentation: We herein present a 68-year-old Chinese woman initially diagnosed with advanced multiple intra-abdominal and pelvic round cell liposarcoma. She refused to receive cytotoxic chemotherapy and received apatinib as the first-line therapy, a novel tyrosine kinase inhibitor of vascular endothelial growth factor receptor-2 that has been used in the treatment of patients with metastatic gastric cancer who progressed with 2 or more chemotherapy regimens. This patient was partially responsive to apatinib with a dose of 500 mg daily. No serious drug-related side effects were observed. Conclusion: Our findings indicate that some cases of liposarcoma may be responsive to antiangiogenic agent apatinib. Randomized clinical studies are needed to further confirm the efficacy and safety of apatinib in the clinical treatment of liposarcoma. PMID:27495042

To compare the safety and efficacy, in treating acute otitis media (AOM) in children, of a new formulation of amoxicillin/clavulanate potassium (Augmentin) oral suspension providing 45/6.4 mg/kg/day and administered twice daily (bid) for 5 and 10 days, respectively, with the safety and efficacy of the original formulation providing 40/10 mg/kg/day and administered three times daily (tid) for 10 days. Eight hundred sixty-eight children ages 2 months to 12 years with AOM were randomly assigned to one of the three treatment groups. Stringent criteria were used for the diagnosis of AOM and for determinations of "cure" and "improvement." Subjects were reexamined on Days 12 to 14 and 32 to 38. Among subjects whose treatment and follow-up conformed fully to protocol, the proportion of treatment successes (clinically cured or improved) on Days 12 to 14 was 78.8% (149 of 189) in the tid 10-day group, 86.5% (154 of 178) in the bid 10-day group and 71.1% (140 of 197) in the bid 5-day group. Corresponding values on Days 32 to 38 were 64.2% (95 of 148) in the tid 10-day group, 63.1% (94 of 149) in the bid 10-day group and 57.8% (93 of 161) in the bid 5-day group. None of the differences between the tid 10-day regimen and either of the 2 bid regimens were statistically significant, but the bid 10-day regimen was significantly more effective than the bid 5-day regimen in younger subjects. In the study population as a whole, results were similar to those in per protocol subjects. Overall the incidence of protocol-defined diarrhea was 26.7% (74 of 277) in the tid 10-day group, compared with 9.6% (27 of 280) in the bid 10-day group (P < 0.0001) and 8.7% (25 of 286) in the bid 5-day group (P < 0.0001). In comparison with the original formulation of Augmentin administered tid for 10 days in the treatment of AOM in children, the new formulation administered bid for 10 days provides at least equivalent efficacy and causes substantially less diarrhea. Administration for 5 days appears not to provide equivalent efficacy, but the difference appears limited to younger children and the margin of difference is small.

Objective Evaluate safety/tolerability/efficacy of MK-8242 in subjects with refractory/recurrent AML. Methods MK-8242 was dosed p.o. QD (30–250 mg) or BID (120–250 mg) for 7on/7off in 28-day cycle. Dosing was modified to 7on/14off, in 21-day cycle (210 or 300 mg BID). Results 26 subjects enrolled (24 evaluable for response); 5/26 discontinued due to AEs. There were 7 deaths; 1 (fungal pneumonia due to marrow aplasia) possibly drug-related. With the 7on/7off regimen, 2 subjects had DLTs in the 250 mg BID group (both bone marrow failure and prolonged cytopenia). With the 7on/14off, no DLTs were observed in 210 mg BID or 300 mg BID (doses >300 mg not tested). Best responses were: 1/24 PR (11 weeks;120 mg QD, 7on/7off); 1/24 CRi (2 weeks;210 mg BID, 7on/14off); 1/24 morphologic leukemia-free state (4 weeks; 250 mg BID, 7on/7off). PK on Day7 at 210 mg BID revealed AUC0-12hr 8.7 μM*hr, Cmax 1.5 μM (n=5, Tmax, 2–6 hr), T1/2 7.9 hr, CLss/F 28.8 L/hr, and Vss/F 317 L. Conclusions The 7on/14off regimen showed a more favorable safety profile; no MTD was established. Efficacy was seen using both regimens providing impetus for further study of HDM2 inhibitors in subjects with AML. PMID:27544076

Apremilast, an oral phosphodiesterase 4 inhibitor, downregulates intracellular inflammatory mediator synthesis by elevating cyclic adenosine monophosphate levels. The PALACE 2 trial evaluated apremilast efficacy and safety in patients with active psoriatic arthritis (PsA) despite prior conventional disease-modifying antirheumatic drugs and/or biologic therapy. Eligible patients were randomized (1:1:1) to placebo, apremilast 20 mg BID, or apremilast 30 mg BID. At Week 16, patients with swollen and tender joint count improvement < 20% entered early escape, with placebo patients rerandomized (1:1) to apremilast 20 mg BID or 30 mg BID while apremilast patients continued on their initial apremilast dose. At Week 24, patients remaining on placebo were rerandomized to apremilast 20 mg BID or 30 mg BID. The primary endpoint was the proportion of patients achieving > 20% improvement in American College of Rheumatology response criteria (ACR20) at Week 16. In the intent-to-treat population (N = 484), ACR20 at Week 16 was achieved by more patients receiving apremilast 20 mg BID [37.4% (p = 0.0002)] and 30 mg BID [32.1% (p = 0.0060)] versus placebo (18.9%). Clinically meaningful improvements in signs and symptoms of PsA, physical function, and psoriasis were observed with apremilast through Week 52. The most common adverse events were diarrhea, nausea, headache, and upper respiratory tract infection. Diarrhea and nausea generally occurred early and usually resolved spontaneously with continued treatment. Laboratory abnormalities were infrequent and transient. Apremilast demonstrated clinical improvements in PsA for up to 52 weeks, including signs and symptoms, physical function, and psoriasis. No new safety signals were observed.

The wisdom of the crowd playing The Price Is Right.

PubMed

Lee, Michael D; Zhang, Shunan; Shi, Jenny

2011-07-01

In The Price Is Right game show, players compete to win a prize, by placing bids on its price. We ask whether it is possible to achieve a "wisdom of the crowd" effect, by combining the bids to produce an aggregate price estimate that is superior to the estimates of individual players. Using data from the game show, we show that a wisdom of the crowd effect is possible, especially by using models of the decision-making processes involved in bidding. The key insight is that, because of the competitive nature of the game, what people bid is not necessarily the same as what they know. This means better estimates are formed by aggregating latent knowledge than by aggregating observed bids. We use our results to highlight the usefulness of models of cognition and decision-making in studying the wisdom of the crowd, which are often approached only from non-psychological statistical perspectives.

Network analysis of online bidding activity

NASA Astrophysics Data System (ADS)

Yang, I.; Oh, E.; Kahng, B.

2006-07-01

With the advent of digital media, people are increasingly resorting to online channels for commercial transactions. The online auction is a prototypical example. In such online transactions, the pattern of bidding activity is more complex than traditional offline transactions; this is because the number of bidders participating in a given transaction is not bounded and the bidders can also easily respond to the bidding instantaneously. By using the recently developed network theory, we study the interaction patterns between bidders (items) who (that) are connected when they bid for the same item (if the item is bid by the same bidder). The resulting network is analyzed by using the hierarchical clustering algorithm, which is used for clustering analysis for expression data from DNA microarrays. A dendrogram is constructed for the item subcategories; this dendrogram is compared to a traditional classification scheme. The implication of the difference between the two is discussed.

Multi-Objective Bidding Strategy for Genco Using Non-Dominated Sorting Particle Swarm Optimization

NASA Astrophysics Data System (ADS)

Saksinchai, Apinat; Boonchuay, Chanwit; Ongsakul, Weerakorn

2010-06-01

This paper proposes a multi-objective bidding strategy for a generation company (GenCo) in uniform price spot market using non-dominated sorting particle swarm optimization (NSPSO). Instead of using a tradeoff technique, NSPSO is introduced to solve the multi-objective strategic bidding problem considering expected profit maximization and risk (profit variation) minimization. Monte Carlo simulation is employed to simulate rivals' bidding behavior. Test results indicate that the proposed approach can provide the efficient non-dominated solution front effectively. In addition, it can be used as a decision making tool for a GenCo compromising between expected profit and price risk in spot market.

Robust Multi-unit Auction Protocol against False-name Bids

NASA Astrophysics Data System (ADS)

Yokoo, Makoto; Sakurai, Yuko; Matsubara, Shigeo

This paper presents a new multi-unit auction protocol (IR protocol) that is robust against false-name bids. Internet auctions have become an integral part of Electronic Commerce and a promising field for applying agent and Artificial Intelligence technologies. Although the Internet provides an excellent infrastructure for executing auctions, the possibility of a new type of cheating called false-name bids has been pointed out. A false-name bid is a bid submitted under a fictitious name. A protocol called LDS has been developed for combinatorial auctions of multiple different items and has proven to be robust against false-name bids. Although we can modify the LDS protocol to handle multi-unit auctions, in which multiple units of an identical item are auctioned, the protocol is complicated and requires the auctioneer to carefully pre-determine the combination of bundles to obtain a high social surplus or revenue. For the auctioneer, our newly developed IR protocol is easier to use than the LDS, since the combination of bundles is automatically determined in a flexible manner according to the declared evaluation values of agents. The evaluation results show that the IR protocol can obtain a better social surplus than that obtained by the LDS protocol.

A Bidding Methodology by Nash Equilibrium for Finite Generators Participating in Imperfect Electricity Markets

NASA Astrophysics Data System (ADS)

Satyaramesh, P. V.

2014-01-01

This paper presents an application of finite n-person non-cooperative game theory for analyzing bidding strategies of generators in a deregulated energy marketplace with Pool Bilateral contracts so as to maximize their net profits. A new methodology to build bidding methodology for generators participating in oligopoly electricity market has been proposed in this paper. It is assumed that each generator bids a supply function. This methodology finds out the coefficients in the supply function of generators in order to maximize benefits in an environment of competing rival bidders. A natural choice for developing strategies is Nash Equilibrium (NE) model incorporating mixed strategies, for solving the bidding problem of electrical market. Associated optimal profits are evaluated for a combination of set of pure strategies of bidding of generators, and payoff matrix has been constructed. The optimal payoff is calculated by using NE. An attempt has also been made to minimize the gap between the optimal payoff and the payoff obtained by a possible mixed strategies combination. The algorithm is coded in MATLAB. A numerical example is used to illustrate the essential features of the approach and the results are proved to be the optimal values.

Group search optimiser-based optimal bidding strategies with no Karush-Kuhn-Tucker optimality conditions

NASA Astrophysics Data System (ADS)

Yadav, Naresh Kumar; Kumar, Mukesh; Gupta, S. K.

2017-03-01

General strategic bidding procedure has been formulated in the literature as a bi-level searching problem, in which the offer curve tends to minimise the market clearing function and to maximise the profit. Computationally, this is complex and hence, the researchers have adopted Karush-Kuhn-Tucker (KKT) optimality conditions to transform the model into a single-level maximisation problem. However, the profit maximisation problem with KKT optimality conditions poses great challenge to the classical optimisation algorithms. The problem has become more complex after the inclusion of transmission constraints. This paper simplifies the profit maximisation problem as a minimisation function, in which the transmission constraints, the operating limits and the ISO market clearing functions are considered with no KKT optimality conditions. The derived function is solved using group search optimiser (GSO), a robust population-based optimisation algorithm. Experimental investigation is carried out on IEEE 14 as well as IEEE 30 bus systems and the performance is compared against differential evolution-based strategic bidding, genetic algorithm-based strategic bidding and particle swarm optimisation-based strategic bidding methods. The simulation results demonstrate that the obtained profit maximisation through GSO-based bidding strategies is higher than the other three methods.

Shipping and natural environmental conditions determine the distribution of the invasive non-indigenous round goby Neogobius melanostomus in a regional sea

NASA Astrophysics Data System (ADS)

Kotta, Jonne; Nurkse, Kristiina; Puntila, Riikka; Ojaveer, Henn

2016-02-01

Introductions of non-indigenous species (NIS) are considered a major threat to aquatic ecosystems worldwide. While it is valuable to know the distributions and ranges of NIS, predictive spatial models along different environmental gradients are more useful for management of these species. In this study we modelled how external drivers and local environmental conditions contribute to the spatial distribution of an invasive species using the distribution of the round goby Neogobius melanostomus in the Baltic Sea as an example. Using the collected distribution data, an updated map on the species distribution and its invasion progress in the Baltic Sea was produced. The current range of the round goby observations is extensive, covering all major sub-basins of the Baltic Sea. The most recent observations appeared in the northern regions (Northern Baltic Proper, the Gulf of Bothnia and the Gulf of Finland) and on the eastern and western coasts of southern Sweden. Modelling results show that the distribution of the round goby is primarily related to local abiotic hydrological conditions (wave exposure). Furthermore, the probability of round goby occurrence was very high in areas in close proximity to large cargo ports. This links patterns of the round goby distribution in the Baltic Sea to shipping traffic and suggests that human factors together with natural environmental conditions are responsible for the spread of NIS at a regional sea scale.

Mutations in the superoxide dismutase 1 (SOD1) gene contribute to motoneuron degeneration and are evident in 20% of familial amyotrophic lateral sclerosis cases. Mutant SOD1 induces microglial activation through a stimulation of Toll-like receptors 2 and 4 (TLR2 and TLR4). In the present study, we identified the proapoptotic Bcl-2 family protein Bid as a positive regulator of mutant SOD1-induced TLR-nuclear factor-κB (NF-κB) signaling in microglia. bid-deficient primary mouse microglia showed reduced NF-κB signaling in response to TLR4 activation or exposure to conditioned medium derived from SOD1 (G93A) expressing NSC-34 cells. Attenuation of NF-κB signaling in bid-deficient microglia was associated with lower levels of phosphorylated IKKα/β and p65, with a delayed degradation of IκBα and enhanced degradation of Peli1. Upstream of IKK, we found that Bid interacted with, and promoted, the K63-linked polyubiquitination of the E3 ubiquitin ligase tumor necrosis factor receptor associated factor 6 (TRAF6) in microglia. Our study suggests a key role for Bid in the regulation of TLR4-NF-κB proinflammatory signaling during mutant SOD1-induced disease pathology. Bid promotes TLR4-NF-κB signaling by interacting with TRAF6 and promoting TRAF6 K63-linked polyubiquitination in microglia.
