[Breaking bad news].  

PubMed

Breaking bad news is one of the most stressful duties of the physician in oncology. Among other issues, it includes discussion of cancer diagnosis or the failure of therapy. The oncologist is often puzzled by an apprehension regarding the delivery of bad news. The fear to be exposed to unexpected strong emotional reactions by the patient, such as aggression or despair, may cause the oncologist to adopt unproductive coping strategies such as discussion about technical details while avoiding to deliver the main message. However, good communication skills are the key for a satisfying conversation with the patient. The oncologists' discomfort induced by the above mentioned apprehension is one of the most important barriers for a successful conversation. PMID:15991627

Giving Bad News: A Qualitative Research Exploration  

PubMed Central

Background: The manner in which healthcare professionals deliver bad news affects the way it is received, interpreted, understood, and dealt with. Despite the fact that clinicians are responsible for breaking bad news, it has been shown that they lack skills necessary to perform this task. Objectives: The purpose of this study was to explore Iranian mothers’ experiences to receive bad news about their children cancer and to summarize suggestions for improving delivering bad news by healthcare providers. Materials and Methods: A qualitative approach using content analysis was adopted. Semi-structured interviews were conducted with 14 mothers from two pediatric hospitals in Iran. Results: Five major categories emerged from the data analysis, including dumping information, shock and upset, emotional work, burden of delivering bad news to the family members, and a room for multidisciplinary approach. Conclusions: Effective communication of healthcare team with mothers is required during breaking bad news. Using multidisciplinary approaches to prevent harmful reactions and providing appropriate support are recommended.

Breaking bad news--a flow diagram.  

PubMed

Breaking bad news is neither an easy nor a popular task. Properly handled, however, it can be given in a positive way that the individual can both accept and understand. There may be a range of emotions and concerns following the telling of bad news. These need to be explored and worked through with each individual. This flow diagram describes the steps in this important process. PMID:8081554

Breaking bad news: issues relating to nursing practice.  

PubMed

The breaking of bad news was traditionally regarded to be the time when a doctor and nurse sat down with a patient and family members to provide information about, for example, a life-limiting diagnosis or a poor prognosis. However, breaking bad news is now generally accepted as a process, not a one-off event, and is considered to refer to any bad, sad or difficult information that alters patients' perceptions of their present and future. Nurses have an important role in the process of providing information and helping patients prepare for, receive, understand and cope with the bad news they have been given. This article aims to help nurses understand the process of breaking bad news and discuss the challenges and difficulties that nurses can face when they are involved with patients who have been given bad news. It also provides guidance with regard to preparing for breaking bad news, giving difficult information, responding to possible reactions, and supporting patients and their relatives after they have received bad news.

Breaking bad news: a Chinese perspective.  

PubMed

The amount of information received by terminal cancer patients about their illness varies across different countries. Many Chinese families object to telling the truth to the patient and doctors often follow the wish of the families. However, a population study in Hong Kong has shown that the majority wanted the information. To address this difference in attitudes, the ethical principles for and against disclosure are analysed, considering the views in Chinese philosophy, sociological studies and traditional Chinese medicine. It is argued that the Chinese views on autonomy and nonmaleficence do not justify non-disclosure of the truth. It is recommended that truth telling should depend on what the patient wants to know and is prepared to know, and not on what the family wants to disclose. The standard palliative care approach to breaking bad news should be adopted, but with modifications to address the 'family determination' and 'death as taboo' issues. PMID:12822851

Is it possible to improve residents breaking bad news skills? A randomised study assessing the efficacy of a communication skills training program  

PubMed Central

Background: This study aims to assess the efficacy of a 40-h training programme designed to teach residents the communication skills needed to break the bad news. Methods: Residents were randomly assigned to the training programme or to a waiting list. A simulated patient breaking bad news (BBN) consultation was audiotaped at baseline and after training in the training group and 8 months after baseline in the waiting-list group. Transcripts were analysed by tagging the used communication skills with a content analysis software (LaComm) and by tagging the phases of bad news delivery: pre-delivery, delivery and post-delivery. Training effects were tested with generalised estimating equation (GEE) and multivariate analysis of variance (MANOVA). Results: The trained residents (n=50) used effective communication skills more often than the untrained residents (n=48): more open questions (relative rate (RR)=5.79; P<0.001), open directive questions (RR=1.71; P=0.003) and empathy (RR=4.50; P=0.017) and less information transmission (RR=0.72; P=0.001). The pre-delivery phase was longer for the trained (1?min 53?s at baseline and 3?min 55?s after training) compared with the untrained residents (2?min 7?s at baseline and 1?min 46?s at second assessment time; P<0.001). Conclusion: This study shows the efficacy of training programme designed to improve residents' BBN skills. The way residents break bad news may thus be improved.

To Tell the Truth Delivering Bad News to Patients  

NSDL National Science Digital Library

This case was developed to teach first-year medical students about medical ethics as they apply to patient communication. Students receive an introductory lecture covering the basics of giving bad news and then are asked to apply what they have learned to a real-life medical situation they read about. The case describes a man who, recently retired, is looking forward to a cruise trip with his wife, but he hasn’t been feeling well. Medical tests show he has colon cancer. Assuming the role of the physician, students must decide when and how to break the bad news. To prepare for their role, students learn the six-step protocol for breaking bad news developed by medical oncologist Dr. Robert Buckman, which they then apply to the case.

Medical training for communication of bad news: A literature review  

PubMed Central

In recent years, medical guidelines for communicating bad news to patients have been published. Training for this task was included in the curricula of undergraduate medical courses, specialization, and continuing medical education. The objective of this review is to evaluate the existing evidence in the literature on the effectiveness of such training. Only seven controlled trials were found, four of which were randomized, and these four indicate an improvement in the trainees. These findings suggest that training undergraduate and postgraduate doctors in skills for communicating bad news may be beneficial but there are important limitations to reach a definitive conclusion. These limitations are discussed in this article.

Human development of the ability to learn from bad news  

PubMed Central

Humans show a natural tendency to discount bad news while incorporating good news into beliefs (the “good news–bad news effect”), an effect that may help explain seemingly irrational risk taking. Understanding how this bias develops with age is important because adolescents are prone to engage in risky behavior; thus, educating them about danger is crucial. We reveal a striking valence-dependent asymmetry in how belief updating develops with age. In the ages tested (9–26 y), younger age was associated with inaccurate updating of beliefs in response to undesirable information regarding vulnerability. In contrast, the ability to update beliefs accurately in response to desirable information remained relatively stable with age. This asymmetry was mediated by adequate computational use of positive but not negative estimation errors to alter beliefs. The results are important for understanding how belief formation develops and might help explain why adolescents do not respond adequately to warnings.

Wrapping up the bad news - HIV assembly and release  

PubMed Central

The late Nobel Laureate Sir Peter Medawar once memorably described viruses as ‘bad news wrapped in protein’. Virus assembly in HIV is a remarkably well coordinated process in which the virus achieves extracellular budding using primarily intracellular budding machinery and also the unusual phenomenon of export from the cell of an RNA. Recruitment of the ESCRT system by HIV is one of the best documented examples of the comprehensive way in which a virus hijacks a normal cellular process. This review is a summary of our current understanding of the budding process of HIV, from genomic RNA capture through budding and on to viral maturation, but centering on the proteins of the ESCRT pathway and highlighting some recent advances in our understanding of the cellular components involved and the complex interplay between the Gag protein and the genomic RNA.

Preparing prelicensure and graduate nursing students to systematically communicate bad news to patients and families.  

PubMed

Communicating bad news, otherwise known as difficult conversations, is a complex communication skill that requires didactic learning and practical application. Students learn that what may be interpreted as bad news is determined by the recipient and not by the person who is delivering the news. Learning a systematic approach, such as the SPIKES (Setting, Perception, Invitation, Knowledge, Empathy, Strategy/Summary) mnemonic, prepares prelicensure and graduate nursing students for difficult conversations with patients and families in the clinical setting. Role-playing commonly includes clinical scenarios, and using video recording and playback of the encounters in such scenarios is one method of learning the systematic approach to communicating bad news. Follow-up practice after application in the clinical setting and feedback from faculty and mentors are essential for nursing students to achieve competence in this complex set of communication skills.

The development of a structured rating schedule (the BAS) to assess skills in breaking bad news  

PubMed Central

There has been considerable interest in how doctors break bad news, with calls from within the profession and from patients for doctors to improve their communication skills. In order to aid clinical training and assessment of the skills used in breaking bad news there is a need for a reliable, practical and valid, structured rating schedule. Such a rating schedule was compiled from agreed criteria in the literature. Video-taped recordings of simulated consultations breaking bad news were independently assessed by three raters using the schedule and compared to three experts who gave global ratings. The primary outcome measures were internal consistency of the schedule and level of agreement between raters. The internal consistency was high with a Cronbach's alpha of 0.93. Agreement between raters using the schedule was moderate to good. The majority of the variation in scores was due to the differences in skills demonstrated in the interviews. The agreement between raters not using the schedule was poor. The BAS provides a simple to use, reliable, and consistent rating schedule for assessing skills used in breaking bad news. It could be a valuable aid to teaching this difficult task. © 1999 Cancer Research Campaign

A Synthesis of the Literature on Breaking Bad News or Truth Telling: Potential for Research in India  

PubMed Central

The high incidence of fatal diseases, inequitable access to health care, and socioeconomic disparities in India generate plentiful clinical bad news including diagnosis of a life-limiting disease, poor prognosis, treatment failure, and impending death. These contexts compel health care professionals to become the messengers of bad news to patients and their families. In global literature on breaking bad news, there is very little about such complex clinical interactions occurring in India or guiding health care providers to do it well. The purpose of this article is to identify the issues for future research that would contribute to the volume, comprehensiveness, and quality of empirical literature on breaking bad news in clinical settings across India. Towards this end, we have synthesized the studies done across the globe on breaking bad news, under four themes: (a) deciding the amount of bad news to deliver; (b) attending to cultural and ethical issues; (c) managing psychological distress; and (d) producing competent messengers of bad news. We believe that robust research is inevitable to build an indigenous knowledge base, enhance communicative competence among health care professionals, and thereby to improve the quality of clinical interactions in India.

Preferences and attitudes of the Saudi population toward receiving medical bad news: A primary study from Riyadh city  

PubMed Central

Background: Breaking bad news is one of the most stressful and difficult things a physician has to do. Good communication skills are required in order to ensure that bad news is delivered in a humane but effective way. Objectives: This study was designed to explore the preferences and attitude of the Saudi population toward receiving bad news. Second, it was to identify the associations between preferences, attitudes, and sociodemographic characteristics. Materials and Methods: This was a cross-sectional study conducted during the month of April 2009 in Riyadh. Data were collected from 1013 adult Saudis. Stratified random sampling technique was used through a self-administered questionnaire. Results: In this study, 474 (46.8%) were males and 539 (53.2%) were females. Almost two-third of the participants preferred to be the first to receive the bad news. A majority of the participants 695 (68.6%) preferred to be told the bad news at a private place, whereas, 441 (43.5%) preferred to be told by the head of the medical team. Moreover, almost half of the participants would like the one who breaks the bad news to remain with them to give them some more information about the disease. Significant associations were observed between participants' perception and attitude with age, marital status, gender, and education (P < 0.001), respectively. Conclusion: Factors such as marital status, age, and gender, and education play significant roles in how bad news is received. Understanding what is important in the process of breaking bad news may help in determining how best to perform this challenging task.

Breaking bad news of cancer diagnosis - Perception of the cancer patients in a rural community in Malaysia  

PubMed Central

Context: Breaking of bad news is an important component in the management of cancer patients. Aims: This study aimed to assess the perceptions of breaking bad news of cancer diagnosis. Settings and Design: It was a cross-sectional study using Breaking Bad News Assessment Schedule (BAS) questionnaire on cancer patients in Serian district. Materials and Methods: Using snowballing sampling method, a total of 134 patients were interviewed face-to-face after the consent was obtained from each of the respondents. Statistical Analysis Used: Data was entered and analyzed using SPSS version 19.0. Results: Majority were comfortable with the current method of breaking bad news. The main aspects found to be the areas of concern were the importance of the usage of body language, management of time and identifying patients’ key area of concerns. There were significant difference between sex and “information giving” (P = 0.028) and “general consideration” (P = 0.016) and also between “the age and setting the scene” (P = 0.042). Significant difference was also found between the types of cancer and “the setting of scene” (P = 0.018), “breaking bad news technique” (P = 0.010), “eliciting concerns” (P = 0.003) and “information giving” (P = 0.004). Conclusion: Good and effective communication skill of breaking bad news is vital in the management of cancer patients. As the incidence of new cases of cancer increase every year, breaking of bad news has become a pertinent to the medical professionals’ role. Specific aspects of communication skills based on local characteristics should be more emphasized in the formulation of training for doctors.

Patient communication in radiology: current status of breaking bad news among radiologists and radiology trainees in Pakistan.  

PubMed

Breaking bad news can be an intimidating task for any physician. The aim of this study was to record the practices of breaking bad news to the patients by Pakistani radiologists and trainees. The radiologists and trainees attending the 26th National Radiological Conference in October 2010 in Karachi, Pakistan, were surveyed. The response rate was 76%. The respondents included residents (51%), private practicing radiologists (28%), academic radiologists (13%), and other trainees (8%). Most of the academic radiologists communicated with their patients. The daily frequency of breaking bad news by residents was noted, which was highest in the public teaching hospitals (71%). For severe abnormalities such as malignancy, 50% residents, 55% of the academic radiologists and 74% of the private practicing radiologists were very uncomfortable in disclosure of results. Differences in frequency of communication with patients were noticed with both different training levels, and different settings of practice in a developing country. PMID:24112271

Perceptions of Receiving Bad News about Cancer among Bone Cancer Patients in Sarawak General Hospital - A Descriptive Study  

PubMed Central

Background: This study aimed to determine the perceptions and expectations of bone cancer patients with respect to their doctors and the breaking of bad news as well as the environment in which the news was delivered. Methods: A cross-sectional study using a pretested 41-item questionnaire was conducted using convenience sampling among bone cancer patients in Sarawak General Hospital. Face-to-face interviews were conducted after consent was obtained. Data were analysed using SPSS version 16 (SPSS Inc., IL, US). Results: A total of 30 patients were interviewed. The majority of the respondents were younger than 40-years-old, Malays, and female. All of the respondents perceived that they received news in a comfortable place, agreed that the doctor used simple language and appropriate words during the interaction, and believed that the way the doctor delivered the news might influence their life. The majority of the respondents reported that their news was received without interruption, that the doctor was sitting close but without making physical contact, and time was given for patient to ask questions and they were informed accordingly. Conclusion: Delivering bad news regarding cancer is an important communication skill and a complex task that can be learned and acquired. Specially tailored training is proposed to improve medical practice in this area.

Considering Patients' Mental Capacity When Giving Them Bad News May Help Their Well-Being: A Case of Suicide Attempt after Being Informed of Lung Cancer Diagnosis  

PubMed Central

Mental capacity is a central determinant of patients' ability to make autonomous decisions about their care and deal with bad news. Physicians should be cognizant of this when giving patients bad news in efforts to help them to cope with the illness and to avoid a deterioration of their mental well-being. To show the importance of this concept, a case of suicide attempt with lung cancer is exemplified. A 76-year-old woman attempted suicide after receiving a diagnosis of lung cancer. Her recent life had been emotionally turbulent and she did not have sufficient mental capacity to accept and cope with this truth. She developed depression before attempting suicide.

Progress toward the 1990 objectives for sexually transmitted diseases: good news and bad.  

PubMed Central

The problem of sexually transmitted diseases (STDs) in the United States has been growing, in both scope and complexity, at an alarming rate. As evidence of the emergence of these diseases as a primary national concern, the Surgeon General has designated them as 1 of 15 priority areas in which further actions are required to improve the health of the American people. The key targets for the 1990 objectives for the nation in the STD area include reducing the incidence of gonorrhea; gonococcal pelvic inflammatory disease; and primary, secondary, and congenital syphilis. This report updates progress toward these objectives. There is good news with respect to the continuing success of proven methods in preventing and controlling both gonorrhea and syphilis. However, the picture is less bright with respect to control of other STDs that have gained new prominence--Chlamydia, herpesvirus, human papillomavirus, and human T-cell lymphotropic virus type III infections. Escalating interest in STDs reflects more recent appreciation of their relation to reproductive outcomes. STD organisms clearly have a far-reaching effect on the nation's population, including the capacity to reproduce, the rate of perinatal infection, the incidence of genital cancers, and the occurrence of acquired immune deficiency syndrome (AIDS).(ABSTRACT TRUNCATED AT 250 WORDS)

Breaking the "bad" news to patients and families: preparing to have the conversation about end-of-life and hospice care.  

PubMed

The ability to compassionately communicate difficult or "bad news" to a patient and family is essential to the provision of quality care at the end-of-life. Preparing to have these conversations requires a deliberate multilevel approach that includes: 1) becoming comfortable with end-of-life issues; 2) understanding the scope of the experiences from the patient's and family's perspectives; 3) understanding the full range of choices and options you can offer patients and families regarding their care (including hospice care); 4) developing a "can do" approach toward your involvement with end-of-life care; and 5) learning to effectively share and receive information in a compassionate manner. The following article explores this multilevel approach in an effort to assist physicians and other health care professions in supporting patients and families in their transition from curative care to hospice and palliative care.

Ocean acoustics at BBN and beyond  

NASA Astrophysics Data System (ADS)

Earlier known exclusively as underwater acoustics, ocean acoustics was pursued almost from BBN's beginning, the firm created by Richard Bolt and Leo Beranek. Ship noise, including that of submarines, and also sonar detection performance are perhaps still classified as underwater acoustics, while sound propagation and noise in the ocean have come to be classified as ocean acoustics. Given its creators, it is no surprise that contributions at BBN to ocean acoustics to about 1970 were based on fundamental concepts in architectural acoustics. These are in essence a set of geometrical ideas within which complicated multi-mode waves propagating in rooms can be reduced to simple theoretical and measurable aggregates expressing the mean-square wave motion. Thus, ray-averaged theories of propagation, wave coherence, and noise in the ocean were developed and used at BBN, as they were elsewhere, and are still in use today. By about 1970 it became clear that improved measurement tools, and increased understanding of the ocean state, including the bottom, could be exploited by theories and measurements of the phase as well as the mean-square motion. This story is traced from the perspective of those at BBN in the early years, to the present state of ocean acoustics.

Good news, bad news on proliferation  

SciTech Connect

While Argentina and Brazil now seem less likely to acquire nuclear weapons, Indian and Pakistani intentions remain uncertain. The Israeli nuclear program and recent allegations of black-marketing are even more disturbing. The author notes the positive developments in Latin America and some hopeful signs in South Asia, despite uncertainties over their final outcome. He finds Israel's program the most disturbing because of the deployment of Jericho II missiles and indications that Israel possesses a fully militarized nuclear force which was developed by illegal means. These activities could politicize the Non-Proliferation Treaty review conference. 14 references.

BAD Times  

NSDL National Science Digital Library

The Black Americans for Democracy (BAD) Times started publication in 1971, growing out of the activist efforts and movement started in the late 1960s on the campus of the University of Arkansas. The BAD organization started life in 1970 in the old student union building on campus, and became well known for their activism and calls for greater integration of student life, university programs, and athletics. The newspaper can claim at least one student who became very well-known, the author E. (Everett) Lynn Harris, who was the BAD treasurer. This digital collection offers interested parties access to twenty issues of newspapers published by the group from 1971 to 1977.

Bad aorta.  

PubMed

As its outcomes improve, cardiac surgery has been performed on more and more cases which were previously considered to be difficult to deal with. However, there are still a number of problems to be solved regarding surgery on patients with severe sclerotic lesions in the ascending aorta, which we collectively call "bad aorta". Concerning a preoperative assessment of the ascending aorta, our report revealed no relationship between the severity of calcification detected with a preoperative non-enhanced CT and the aortic lesion found during the surgery. Meanwhile, an intraoperative epiaortic ultrasound enables us to make high-quality evaluations of the aorta without imposing much burden on the patient. This modality may be essential for cardiac surgery. As for surgical management for bad aorta, quite a few methods have been reported to this point, but the overall operative mortality rate and cerebrovascular accident rate are relatively high, at a little <10 %, respectively. With the recent cross-clamping method under short-term total circulatory arrest (TCA), however, the results are much better; these rates total around 5 %. Further improvement is expected in the outcome of cardiac surgery on bad aorta cases by establishing a modality to evaluate sclerotic lesions in the ascending aorta with epiaortic ultrasound and by selecting a proper procedure for each case.

BBN and the CMB constrain light, electromagnetically coupled WIMPs  

NASA Astrophysics Data System (ADS)

In the presence of a light weakly interacting massive particle (WIMP; m??30 MeV), there are degeneracies among the nature of the WIMP (fermion or boson), its couplings to the standard-model particles (electromagnetic or to neutrinos only), the WIMP mass m?, and the number of equivalent neutrinos beyond the standard model ?N? (including possible sterile neutrinos). These degeneracies cannot be broken by the cosmic microwave background (CMB) constraint on the effective number of neutrinos, Neff. However, big bang nucleosynthesis (BBN) is affected by the presence of a light WIMP and equivalent neutrinos, so the combination of BBN and CMB constraints can help to break some of these degeneracies. Here, the BBN predictions for the primordial abundances of deuterium and He4 (along with He3 and Li7) in the presence of a light WIMP and equivalent neutrinos are explored, and the most recent estimates of their observationally determined relic abundances are used to limit the light-WIMP mass, the number of equivalent neutrinos, and the present Universe baryon density (?Bh2). These constraints are explored here for Majorana and Dirac fermion WIMPs, as well as for real and complex scalar WIMPs that couple to electrons, positrons, and photons. In a separate paper, this analysis is repeated for WIMPs that couple only to the standard-model neutrinos, and the constraints for the two cases are contrasted. In the absence of a light WIMP, but allowing for ?N? equivalent neutrinos, the combined BBN and CMB constraints favor Neff=3.46±0.17, ?Bh2=0.0224±0.0003, and ?N?=0.40±0.17 (all at a 68% C.L.). In this case, standard BBN (?N?=0) is disfavored at ˜98% confidence, and the presence of one sterile neutrino (?N?=1) is disfavored at ?99% confidence. Allowing for a light WIMP and ?N? equivalent neutrinos together, the combined BBN and CMB data provide lower limits to the WIMP masses (m??0.5-5 MeV) that depend on the nature of the WIMP, favor m?˜8 MeV (with small variations depending on the WIMP type) slightly over standard BBN, and loosen the constraints on the allowed number of equivalent neutrinos, ?N?=0.65-0.35+0.46. As a result, while ?N?=0 is still disfavored at ˜95% confidence when there is a light WIMP, ?N?=1 is now allowed.

Solar neutrino constraints on the BBN production of Li  

NASA Astrophysics Data System (ADS)

Using the recent WMAP determination of the baryon-to-photon ratio, 1010?=6.14 to within a few percent, big bang nucleosynthesis (BBN) calculations can make relatively accurate predictions of the abundances of the light element isotopes which can be tested against observational abundance determinations. At this value of ?, the 7Li abundance is predicted to be significantly higher than that observed in low metallicity halo dwarf stars. Among the possible resolutions to this discrepancy are (1) 7Li depletion in the atmosphere of stars, (2) systematic errors originating from the choice of stellar parameters—most notably the surface temperature, and (3) systematic errors in the nuclear cross sections used in the nucleosynthesis calculations. Here, we explore the last possibility, and focus on possible systematic errors in the 3He(?,?)7Be reaction, which is the only important 7Li production channel in BBN. The absolute value of the cross section for this key reaction is known relatively poorly both experimentally and theoretically. The agreement between the standard solar model and solar neutrino data thus provides additional constraints on variations in the cross section (S34). Using the standard solar model of Bahcall, and recent solar neutrino data, we can exclude systematic S34 variations of the magnitude needed to resolve the BBN 7Li problem at the ?95% C.L., or more strongly, depending on the Li observations used. Additional laboratory data on 3He(?,?)7Be will sharpen our understanding of both BBN and solar neutrinos, particularly if care is taken in determining the absolute cross section and its uncertainties. Nevertheless, it is already clear that this “nuclear fix” to the 7Li BBN problem is unlikely; other possible solutions are briefly discussed.

The triple-alpha reaction and the A=8 gap in BBN and Population III stars .  

NASA Astrophysics Data System (ADS)

We investigated the effect of a variation of fundamental constants on primordial element production in Big Bang nucleosynthesis (BBN) and primordial stellar evolution. We focused on the effect of a possible change in the nucleon-nucleon interaction on nuclear reaction rates involving A = 8 and 5 unstable nuclei. While the triple-alpha process 4He(alpha alpha ,gamma )12C is normally not effective in BBN, its rate is very sensitive to the position of the ``Hoyle state" and could in principle be drastically affected if 8Be were stable during BBN.

BadAds  

NSDL National Science Digital Library

The creators of BadAds believe that advertising has become far too intrusive in American lives. Along with TV, magazine, radio ads, and billboards, advertisements and commercials are popping up in movie theatres, schools, public bathrooms, and even on stickers on fruit. Four criteria determine whether advertising is intrusive: an inability to turn the ad off; its entrance into your home without your consent; your lack of choice whether or not to watch it; and ads that don't support anything in particular and may actually cost you money. Rather than just venting about intrusive advertising, BadAds urges visitors to become active in the fight against bad ads by writing complaint letters to a host of venues that support intrusive advertising including movie theaters, sporting venues, television networks, and the heads of educational institutions. BadAds offers instructions on writing complaint letters as well as many suggestions as to who should receive these letters.

Breaking the News in Spinal Cord Injury  

PubMed Central

Summary: Breaking the bad news in terms of prognosis for significant motor recovery following a neurologically complete spinal cord injury (SCI) is one of the most difficult tasks for the spinal cord medicine specialist. Learning the skills to facilitate this communication is extremely important to better assist patients to understand their prognosis as well as foster hope for their future. If bad news is delivered poorly it can cause confusion and long-lasting distress and resentment; if done well, it may assist understanding, adjustment, and acceptance. This article provides the physician who cares for patients with SCI with some concepts to consider when discussing prognosis with patients and their families.

It is argued that many synthetic metals, including high temperature superconductors are ``bad metals`` with such a poor conductivity that the usual mean-field theory of superconductivity breaks down because of anomalously large classical and quantum fluctuations of the phase of the superconducting order parameter. Some consequences for high temperature superconductors are described.

Chemoprevention of BBN-Induced Bladder Carcinogenesis by the Selective Estrogen Receptor Modulator Tamoxifen1  

PubMed Central

Bladder cancer is the fifth most frequent tumor in men and ninth in women in the United States. Due to a high likelihood of recurrence, effective chemoprevention is a significant unmet need. Estrogen receptors (ERs), primarily ER?, are expressed in normal urothelium and urothelial carcinoma, and blocking ER function with selective ER modulators such as tamoxifen inhibits bladder cancer cell proliferation in vitro. Herein, the chemoprotective potential of tamoxifen was evaluated in female mice exposed to the bladder-specific carcinogen, N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN). Carcinogen treatment resulted in a 76% tumor incidence and increased mean bladder weights in comparison to controls. In contrast, mice receiving tamoxifen concurrent (8–20 weeks) or concurrent and subsequent (8–32 weeks) to BBN administration had no change in bladder weight and only 10% to 14% incidence of tumors. Non-muscle-invasive disease was present in animals treated with tamoxifen before (5–8 weeks) or after (20–32 weeks) BBN exposure, while incidence of muscle-invasive bladder carcinoma was reduced. ER? was present in all mice and thus is a potential mediator of the tamoxifen chemoprotective effect. Surprisingly, ER? expression, which was detected in 74% of the mice exposed to BBN alone but not in any controlmice, was correlated with tumor incidence, indicating a possible role for this receptor in carcinogen-induced urothelial tumorigenesis. Thus, these data argue that both ER? and ER? play a role in modulating carcinogen-induced bladder tumorigenesis. Administration of tamoxifen should be tested as a chemopreventive strategy for patients at high risk for bladder cancer recurrence.

Big Black Holes Mean Bad News for Stars (diagram)  

NASA Technical Reports Server (NTRS)

[figure removed for brevity, see original site] Poster Version Suppression of Star Formation from Supermassive Black Holes

This diagram illustrates research from NASA's Galaxy Evolution Explorer showing that black holes -- once they reach a critical size -- can put the brakes on new star formation in elliptical galaxies.

In this graph, galaxies and their supermassive black holes are indicated by the drawings (the black circle at the center of each galaxy represents the black hole). The relative masses of the galaxies and their black holes are reflected in the sizes of the drawings. Blue indicates that the galaxy has new stars, while red means the galaxy does not have any detectable new stars.

The Galaxy Evolution Explorer observed the following trend: the biggest galaxies and black holes (shown in upper right corner) are more likely to have no observable star formation (red) than the smaller galaxies with smaller black holes. This is evidence that black holes can create environments unsuitable for stellar birth.

The white line in the diagram illustrates that, for any galaxy no matter what the mass, its black hole must reach a critical size before it can shut down star formation.

In this study, a new combination of bimodal 188Re-(DXR)-liposome-BBN radiochemotherapeutics was designed and studied for treating solid pancreatic tumor by intravenous administration. The in vivo nuclear microSPECT/CT imaging of tumor targeting, prolonged survival time and therapeutic efficacy were evaluated in AR42J malignant pancreatic solid tumor-bearing nude mice. MicroSPECT/CT imaging of 188Re-liposome-BBN pointed to significant targeting in tumors at 24 h after intravenous injection (SUV=2.13 ± 0.98). Co-injection of a blocking dose of cold BBN (4 mg/kg) inhibited the accumulation of 188Re-liposome-BBN in tumors (SUV=1.82 ± 0.31). For therapeutic efficacy, inhibition of tumor growth in mice treated with 188Re-DXR-liposome-BBN was precisely controlled [mean growth inhibition rate (MGI) = 0.092] and had longer survival time [life-span (LS) = 86.96%] than those treated with anticancer drug 188Re-liposome-BBN (MGI = 0.130; LS = 75%), Lipo-Dox-BBN (MGI = 0.666; LS = 3.61%) and untreated control mice. An additive tumor regression effect was observed (CI 0.946) for co-delivery of 188Re-DXR-liposome-BBN radiochemotherapeutics. These results point to the potential benefit of the 188Re-(DXR)-liposome-BBN radiochemotherapeutics for adjuvant cancer treatment with applications in oncology. PMID:22922965

Good news-bad news: the Yin and Yang of immune privilege in the eye  

PubMed Central

The eye and the brain are prototypical tissues manifesting immune privilege (IP) in which immune responses to foreign antigens, particularly alloantigens are suppressed, and even completely inhibited. Explanations for this phenomenon are numerous and mostly reflect our evolving understanding of the molecular and cellular processes underpinning immunological responses generally. IP is now viewed as a property of many tissues and the level of expression of IP varies not only with the tissue but with the nature of the foreign antigen and changes in the limited conditions under which privilege can operate as a mechanism of immunological tolerance. As a result, IP functions normally as a homeostatic mechanism preserving normal function in tissues, particularly those with highly specialized function and limited capacity for renewal such as the eye and brain. However, IP is relatively easily bypassed in the face of a sufficiently strong immunological response, and the privileged tissues may be at greater risk of collateral damage because its natural defenses are more easily breached than in a fully immunocompetent tissue which rapidly rejects foreign antigen and restores integrity. This two-edged sword cuts its swathe through the eye: under most circumstances, IP mechanisms such as blood–ocular barriers, intraocular immune modulators, induction of T regulatory cells, lack of lymphatics, and other properties maintain tissue integrity; however, when these are breached, various degrees of tissue damage occur from severe tissue destruction in retinal viral infections and other forms of uveoretinal inflammation, to less severe inflammatory responses in conditions such as macular degeneration. Conversely, ocular IP and tumor-related IP can combine to permit extensive tumor growth and increased risk of metastasis thus threatening the survival of the host.

Universal thermopower of bad metals  

NASA Astrophysics Data System (ADS)

``Bad metals" are known to have a large linear resistivity at high T that is universally seen near the Mott-Hubbard insulating phase. Less well known is that the thermopower ? (T) of the Mott-Hubbard systems also exhibits simple universal features: (i) close to the insulating phase, where the resistivity has a low-temperature upturn, ? (T) has a pronounced low-T peak that shifts to higher T with doping; (ii) when the resistivity is nearly linear, which occurs at moderate doping, ? (T) has a small low-T peak that shifts to lower T with doping and has a high-T sign change; and (iii) at the highest doping, where the resistivity acquires a T2 term, ? (T) is negative and depends monotonically on T. The universality ? (T) can be understood using the Kelvin formula and the fact that the chemical potential for doped Mott insulators displays similar behavior at high T. The universality is illustrated with the exact solution of the simplest model for a doped Mott insulator at high T.

Guidelines for Submission The Journal's current Guide to Submissions can be found on pages 29-30 of this issue. They have been streamlined a bit and also include a handy check list. This information is also available on JCE Online at http://jchemed.chem.wisc.edu/Journal/Authors/. Wanted: Demo Checkers The Tested Demonstrations column needs people who like to try out demos. Column editor Ed Vitz is looking for additional volunteers to serve as "checkers" for manuscripts that have been submitted to the Journal for possible publication as Tested Demonstrations. A checker is expected to perform two functions: to review the manuscript for accuracy and novelty, and to attempt to perform the demonstration according to the procedure supplied by the author. Checkers may suggest important improvements in demonstration procedures, and for their efforts they are cited in the byline when the manuscript is published. For instance, the demo showing the yellow cascading precipitates (lead iodide) made from potassium iodide and lead nitrate was submitted by Wobbe de Vos and checked by Kim Kostka. The (yellow) cascading precipitates are from "Using Large Glass Cylinders To Demonstrate Chemical Reactions" that appeared in the April 1999 issue of JCE. We prefer that checkers begin the review process (which may in some cases involve procuring supplies) very soon after being contacted so that their review can be completed in the timely manner that authors deserve. Checkers are usually teachers who routinely present lecture demonstrations in their classes in either high school or colleges. We try not to call on checkers more often than once a year, which is one of the reasons for this request. Another is that we lose many highly valued, experienced checkers to retirement or other endeavors. Prospective checkers may want to look at a copy of the JCE Tested Demonstration Evaluation Form. It can be found on the Web at http://www.kutztown.edu/ vitz/TD/TDhome.html. This site also has links to JCE guidelines for prospective authors. Volunteers should contact Vitz by the medium of their preference: Ed Vitz, Editor, Tested Demonstrations, Journal of Chemical Education, Department of Chemistry, Kutztown University, Kutztown, PA 19530; phone: 610/683-4443; fax: 610/683-1352; email: vitz@kutztown.edu.

News from Journal House Perspective on JCE Online Recently a reader asked us for a perspective on JCE Onlinehow the chemical education community is receiving it and how the Journal staff itself views it. We share our responses below. Subscriber Numbers How many people subscribe to JCE Online+? As of June 1, 1999, our records show that 13% of individual JCE subscriptions in the USA include JCE Online+. This percentage has increased significantly during the past year- in June 1998 it was approximately 4% and December 1998 about 7%. Almost all subscribers to JCE Online subscribe to print as well. Since JCE Online has only very recently been made available to institutional subscribers, there are no numbers to report. There has been considerable interest in online from libraries. Given that JCE Online+ is a fairly recent subscriber option and that many subscribers have a wait-and-see approach to any new option, we feel that the numbers above are quite high. The steady growth is encouraging. Online Usage How many people visit our Web site? Statistics for the period January 1, 1999, through May 31, 1999, that may be of interest include:

Total Pages Served 361,115

Total Visits 138,377

Total Unique Visitors 51,744

Total Repeat Visitors 11,536

Average Visit Length 03:05

Average Requests/Visit 10.8

Average Pages/Visit 2.6

Average Daily Visits 916 Online Rationale and Expectations JCE Online is a very important part of the whole Journal, but we do not expect it to supplant print: online and print are very different media. Usage of JCE Online is growing steadily; our subscribers are realizing what we have learned: it is not possible to deliver the Journal in the print medium alone- print is no longer adequate to accomplish our mission. Examples of things not possible in print include:

·JCE Index to all 76 years of Journal issues, available all the time with responses within seconds.

·Supplementary materials that are important to only a limited number of our subscribers; materials that augment laboratory experiments are a good example.

·Supplementary videos, such as the videos, still images, and excerpts from interviews with nuclear chemists that give fuller meaning to the Viewpoints article "Chemistry of the Heaviest Elements- One Atom at a Time" referred to below.

·Internet feature columns are more effective in a dynamic medium. Two that are in place are Mathcad in the Chemistry Curriculum (edited by Theresa Zielinski) and Conceptual Questions and Challenge Problems (edited by William Robinson and Susan Nurrenbern).

·Buyers Guides have their content updated often and link to other useful sites. There is one for books and software and another for supplies and equipment. Elements Added to Periodic Table Two new transuranic elements have been added to the list in the Viewpoints article "Chemistry of the Heaviest ElementsOne Atom at a Time" by Darleane C. Hoffman and Diana M. Lee (JCE, 1999, 76, 331). The new elements have atomic numbers 118 and 116. The path to the discovery of these elements was predicted by Robert Smolanczuk, a young Polish theorist whose calculations led him to conclude that a lead-krypton collision technique could produce element 118, which then decays to element 116. Others questioned his results, but Hoffman invited him to join the team at the Lawrence Berkeley National Laboratory and a decision was made to try out his ideas. The result was almost complete verification of Smolanczuk's calculations. The experimental team was headed by Kenneth E. Gregorich; Darleane Hoffman is one of 15 codiscoverers of element 118. Aw

Bad apples, bad cases, and bad barrels: meta-analytic evidence about sources of unethical decisions at work.  

PubMed

As corporate scandals proliferate, practitioners and researchers alike need a cumulative, quantitative understanding of the antecedents associated with unethical decisions in organizations. In this meta-analysis, the authors draw from over 30 years of research and multiple literatures to examine individual ("bad apple"), moral issue ("bad case"), and organizational environment ("bad barrel") antecedents of unethical choice. Findings provide empirical support for several foundational theories and paint a clearer picture of relationships characterized by mixed results. Structural equation modeling revealed the complexity (multidetermined nature) of unethical choice, as well as a need for research that simultaneously examines different sets of antecedents. Moderator analyses unexpectedly uncovered better prediction of unethical behavior than of intention for several variables. This suggests a need to more strongly consider a new "ethical impulse" perspective in addition to the traditional "ethical calculus" perspective. Results serve as a data-based foundation and guide for future theoretical and empirical development in the domain of behavioral ethics. PMID:20085404

If by chance you were a Journal Ambassador in 1999 but your name was not included, just let us know so that you can be recognized in a future column. Gift Subscription Awards As spring, the season of awards, approaches, we remind you of our handy Gift Certificates (a replica is shown on page 142). A gift of the Journal is not only affordable (gift subscriptions are 37/year (U.S.), 50/year (non-U.S.), but has lasting value. This is a really good way to help someone just starting out on a teaching career. An idea worth sharing comes from Carl Minnier of Essex Community College in Baltimore. He is chair of the Student Awards Committee of the Maryland Section of the ACS. This section has asked for 25 certificates because they honor annually an outstanding student from each of the two-year and four-year colleges within the territory of the Maryland Section.

Classroom Activities for Outreach Many of our readers are involved with outreach programsindividually in their child's class, in a regional group that visits schools, in a van program, or as a demonstrator at their local science museum. Many readers have enthusiastically reported that our Classroom Activities series is a great resource for such programs. Since the Activities are designed for a high school classroom or lab (Activity 24 in this continuing series can be found in this issue), they are purposely not demanding of equipment, facilities, or time. But outreach activities often take place in very restricted environments, perhaps without sinks or electricity, sometimes with limited table space.

A new (68)Ga-labeled BBN peptide with a hydrophilic linker for GRPR-targeted tumor imaging.  

PubMed

Bombesin (BBN) is a peptide exhibiting high affinity for the gastrin-releasing peptide receptor (GRPR), which is overexpressed on several types of cancers. Various GRPR antagonists and agonists have been labeled with radiometals for positron emission tomography (PET) imaging of GRPR-positive tumors. However, unfavorable hepatobiliary excretion such as high intestinal activity may prohibit their clinical utility for imaging abdominal cancer. In this study, the modified BBN peptide with a new hydrophilic linker was labeled with (68)Ga for PET imaging of GRPR-expressing PC-3 prostate cancer xenograft model. GRPR antagonists, MATBBN (Gly-Gly-Gly-Arg-Asp-Asn-D-Phe-Gln-Trp-Ala-Val-Gly-His-Leu-NHCH2CH3) and ATBBN (D-Phe-Gln-Trp-Ala-Val-Gly-His-Leu-NHCH2CH3), were conjugated with 1,4,7-triazacyclononanetriacetic acid (NOTA) and labeled with (68)Ga. Partition coefficient and in vitro stability were also determined. GRPR binding affinity of both tracers was investigated by competitive radioligand binding assay. The in vivo receptor targeting potential and pharmacokinetic of (68)Ga-NOTA-MATBBN were also evaluated in PC-3 prostate tumor model and compared with those of (68)Ga-NOTA-ATBBN. NOTA-conjugated BBN analogs were labeled with (68)Ga within 20 min with a decay-corrected yield ranging from 90 to 95 % and a radiochemical purity of more than 98 %. The specific activity of (68)Ga-NOTA-MATBBN and (68)Ga-NOTA-ATBBN was at least 16.5 and 11.9 GBq/?mol, respectively. The radiotracers were stable in phosphate-buffered saline and human serum. (68)Ga-NOTA-MATBBN was more hydrophilic than (68)Ga-NOTA-ATBBN, as indicated by their log P values (-2.73 ± 0.02 vs. -1.20 ± 0.03). The IC50 values of NOTA-ATBBN and NOTA-MATBBN were similar (102.7 ± 1.18 and 124.6 ± 1.21 nM). The accumulation of (68)Ga-labeled GRPR antagonists in the subcutaneous PC-3 tumors could be visualized via small animal PET. The tumors were clearly visible, and the tumor uptakes of (68)Ga-NOTA-MATBBN and (68)Ga-NOTA-ATBBN were determined to be 4.19 ± 0.32, 4.00 ± 0.41, 2.93 ± 0.35 and 4.70 ± 0.40, 4.10 ± 0.30, 3.14 ± 0.30 %ID/g at 30, 60, and 120 min, respectively. There was considerable accumulation and retention of (68)Ga-NOTA-ATBBN in the liver and intestines. In contrast, the abdominal area does not have much retention of (68)Ga-NOTA-MATBBN. Biodistribution data were in accordance with the PET results, showing that (68)Ga-NOTA-MATBBN had more favorable pharmacokinetics and higher tumor to background ratios than those of (68)Ga-NOTA-ATBBN. At 1 h postinjection, the tumor to liver and intestine of (68)Ga-NOTA-MATBBN were 8.05 ± 0.56 and 21.72 ± 3.47 and the corresponding values of unmodified counterpart were 0.85 ± 0.23 and 3.45 ± 0.43, respectively. GRPR binding specificity was demonstrated by reduced tumor uptake of radiolabeled tracers after coinjection of an excess of unlabeled BBN peptides. (68)Ga-NOTA-MATBBN exhibited GRPR-targeting properties both in vitro and in vivo. The favorable characterizations of (68)Ga-NOTA-MATBBN such as convenient synthesis, specific GRPR targeting, high tumor uptake, and satisfactory pharmacokinetics warrant its further investigation for clinical cancer imaging.

The prevalence of hospital health promotion and disease prevention services: good news, bad news, and policy implications.  

PubMed

In recent years, American health care has shifted toward an emphasis on population health in communities. National data from the American Hospital Association Annual Survey of Hospitals are used to describe the prevalence of 26 services provided by general hospitals that could contribute to health promotion and disease prevention (HPDP). Cross-sectional descriptive analyses, based on national data sources, linked HPDP services to hospital characteristics, and factor analysis identified significant categories of HPDP activities. The results showed that many specific HPDP services are offered by thousands of hospitals, but prevalence, distribution, and availability of the services are uneven across the size and ownership of hospitals and their communities. Policy initiatives could increase the prevalence of hospitals' health promotion and disease prevention services, thereby improving the health status of their communities. PMID:10834083

[64Cu-NOTA-8-Aoc-BBN(7-14)NH2] targeting vector for positron-emission tomography imaging of gastrin-releasing peptide receptor-expressing tissues  

PubMed Central

Radiolabeled peptides hold promise as diagnostic/therapeutic targeting vectors for specific human cancers. We report the design and development of a targeting vector, [64Cu-NOTA-8-Aoc-BBN(7-14)NH2] (NOTA = 1,4,7-triazacyclononane-1,4,7-triacetic acid, 8-Aoc = 8-aminooctanoic acid, and BBN = bombesin), having very high selectivity and affinity for the gastrin-releasing peptide receptor (GRPr). GRPrs are expressed on a variety of human cancers, including breast, lung, pancreatic, and prostate, making this a viable approach toward site-directed localization or therapy of these human diseases. In this study, [NOTA-X-BBN(7-14)NH2] conjugates were synthesized, where X = a specific pharmacokinetic modifier. The IC50 of [NOTA-8-Aoc-BBN(7-14)NH2] was determined by a competitive displacement cell-binding assay in PC-3 human prostate cancer cells using 125I-[Tyr4]-BBN as the displacement ligand. An IC50 of 3.1 ± 0.5 nM was obtained, demonstrating high binding affinity of [NOTA-8-Aoc-BBN] for the GRPr. [64Cu-NOTA-X-BBN] conjugates were prepared by the reaction of 64CuCl2 with peptides in buffered aqueous solution. In vivo studies of [64Cu-NOTA-8-Aoc-BBN(7-14)NH2] in tumor-bearing PC-3 mouse models indicated very high affinity of conjugate for the GRPr. Uptake of conjugate in tumor was 3.58 ± 0.70% injected dose (ID) per g at 1 h postintravenous injection (p.i.). Minimal accumulation of radioactivity in liver tissue (1.58 ± 0.40% ID per g, 1 h p.i.) is indicative of rapid renal-urinary excretion and suggests very high in vivo kinetic stability of [64Cu-NOTA-8-Aoc-BBN(7-14)NH2] with little or no in vivo dissociation of 64Cu2+ from the NOTA chelator. Kidney accumulation at 1 h p.i. was 3.79 ± 1.09% ID per g. Molecular imaging studies in GRPr-expressing tumor models produced high-contrast, high-quality micro-positron-emission tomography images.

Comparative study of 64Cu/NOTA-[D-Tyr6,?Ala11,Thi13,Nle14]BBN(6-14) monomer and dimers for prostate cancer PET imaging  

PubMed Central

Background Gastrin-releasing peptide receptors [GRPR] are highly over-expressed in multiple cancers and have been studied as a diagnostic target. Multimeric gastrin-releasing peptides are expected to have enhanced tumor uptake and affinity for GRPR. In this study, a 64Cu-labeled 1,4,7-triazacyclononane-1,4,7-triacetic acid [NOTA]-monomer and two NOTA-dimers of [D-Tyr6,?Ala11, Thi13, Nle14]bombesin(6-14) ] [BBN(6-14)] were compared. Methods Monomeric and dimeric peptides were synthesized on solid phase support and radiolabeled with 64Cu. NOTA-dimer 1 consists of asymmetrically linked BBN(6-14), while NOTA-dimer 2 has similar spacer between the two BBN(6-14) ligands and the chelator. In vitro GRPR-binding affinities were determined with competitive binding assays on PC3 human prostate cancer cells. In vivo stability and biodistribution of radiolabeled compounds were assessed in Balb/c mice. Cellular uptake and efflux were measured with radiolabeled NOTA-monomer and NOTA-dimer 2 on PC3 cells for up to 4 h. In vivo biodistribution kinetics were measured in PC3 tumor-bearing Balb/c nude mice by ?-positron emission tomography [?PET] imaging and confirmed by dissection and counting. Results NOTA-monomer, NOTA-dimers 1 and 2 were prepared with purity of 99%. The inhibition constants of the three BBN peptides were comparable and in the low nanomolar range. All 64Cu-labeled peptides were stable up to 24 h in mouse plasma and 1 h in vivo. 64Cu/NOTA-dimer 2 featuring a longer spacer between the two BBN(6-14) ligands is a more potent GRPR-targeting probe than 64Cu/NOTA-dimer 1. PC3 tumor uptake profiles are slightly different for 64Cu/NOTA-monomer and 64Cu/NOTA-dimer 2; the monomeric BBN-peptide tracer exhibited higher tumor uptake during the first 0.5 h and a fast renal clearance resulting in higher tumor-to-muscle ratio when compared to 64Cu/NOTA-dimer 2. The latter exhibited higher tumor-to-blood ratio and was retained longer at the tumor site when compared to 64Cu/NOTA-monomer. Lower ratios of tumor-to-blood and tumor-to-muscle in blocking experiments showed GRPR-dependant tumor uptake for both tracers. Conclusion Both 64Cu/NOTA-monomer and 64Cu/NOTA-dimer 2 are suitable for detecting GRPR-positive prostate cancer in vivo by PET. Tumor retention was improved in vivo with 64Cu/NOTA-dimer 2 by applying polyvalency effect and/or statistical rebinding.

Is It Really News?  

NSDL National Science Digital Library

A leading national newspaper has stated that the majority of the information contained in its pages is in the form of advertisements. To investigate this, portions of the local newspaper are distributed to students working in groups. The class first reaches consensus on their definitions of "news" and other general headings (sports, entertainment, etc.). Students then express the ratio of the area of each category to the area of the page as a fraction and decimal. After analyzing the entire newspaper, students decide how much of it is really news.

Caspase Cleavage Enhances the Apoptosis-Inducing Effects of BAD  

PubMed Central

The function of BAD, a proapoptotic member of the Bcl-2 family, is regulated primarily by rapid changes in phosphorylation that modulate its protein-protein interactions and subcellular localization. We show here that, during interleukin-3 (IL-3) deprivation-induced apoptosis of 32Dcl3 murine myeloid precursor cells, BAD is cleaved by a caspase(s) at its N terminus to generate a 15-kDa truncated protein. The 15-kDa truncated BAD is a more potent inducer of apoptosis than the wild-type protein, whereas a mutant BAD resistant to caspase 3 cleavage is a weak apoptosis inducer. Truncated BAD is detectable only in the mitochondrial fraction, interacts with BCL-XL at least as effectively as the wild-type protein, and is more potent than wild-type BAD in inducing cytochrome c release. Human BAD, which is 43 amino acids shorter than its mouse counterpart, is also cleaved by a caspase(s) upon exposure of Jurkat T cells to anti-FAS antibody, tumor necrosis factor alpha (TNF-?), or TRAIL. Moreover, a truncated form of human BAD lacking the N-terminal 28 amino acids is more potent than wild-type BAD in inducing apoptosis. The generation of truncated BAD was blocked by Bcl-2 in IL-3-deprived 32Dcl3 cells but not in Jurkat T cells exposed to anti-FAS antibody, TNF-?, or TRAIL. Together, these findings point to a novel and important role for BAD in maintaining the apoptotic phenotype in response to various apoptosis inducers.

GCM (general circulation model)-data intercomparison: The good news and the bad  

SciTech Connect

General circulation models (GCMs) are being actively used to assess possible climate change due to increasing greenhouse gas concentrations. Because such simulations provide detailed climatic predictions at a wide range of scales, they are of particular interest to those making regional assessments of climatic change. It is especially important that workers using the results of such simulations be aware of some of the limitations of these results. In this study some of the positive results from these model simulations will be shown and some of the deficiencies will also be highlighted. Following an introductory section describing the nature of GCM climate simulations the issue of the spatial scales of such simulations is examined. A comparison of the results of seven GCM simulations of the current climate and the predictions of these models for the changes due to a doubling of CO{sub 2} will be discussed. In these intercomparisons, the spatial scale over which the results are compared varies from global to zonal (longitudinally averaged at a given latitude) to individual slices through the data along specified latitudes or longitudes. Finally, the dangers and pitfalls of relying on simple averages will be highlighted. 19 refs., 9 figs., 1 tab.

First, once one moves past the very smallest stocks, the profitability of momentum strategies declines sharply with firm size. Second, holding size fixed, momentum strategies work better among stocks with low analyst coverage. Finally,

U.s. Farm dilemma: the global bad news is wrong.  

PubMed

World agricultural production is at an all-time high and is climbing fast, especially in the developing countries. Even Africa has ample land and technology to feed its population, given more effective national policies. Higher agricultural output has been stimulated primarily by new technology, but also by investments and improved government policies. Constraints such as cropland shortage, soil erosion, and higher oil prices have been readily surmounted. High-technology agriculture has even overcome some major "systems breaks." Thus U.S. farmers will continue to face commercial surpluses of farm products in world markets in the years ahead. PMID:17816064

PNRS: personalized news retrieval system  

NASA Astrophysics Data System (ADS)

Personal News Retrieval System is a client-server application that delivers news segments on demand in a variety of information networks. At the server side, the news stories are segmented out from the digitized TV broadcast then classified and filtered based on consumers' preferences. At the client side, the user can access the preferred video news through the Web and watch stored video news in preferred order. Browsing preferences can be set based on anchorperson, broadcaster, category, location, top- stories and keywords. This system can be used to set up a news service run by content providers or independent media distribution companies. However, in the news era of enhanced PC/TV appliances, it is foreseeable that the whole system can run in the living room on a personal device. This paper describes the chosen server architecture, limitation of the system and solutions that can be implemented in the future.

NO news is no new news  

USGS Publications Warehouse

In the paper 'NO News', Preston et al. (2004) make a number of erroneous assumptions regarding nitrogen oxide chemistry. These authors also present some very significant misinterpretations of previous research into the effects of various nitrogen oxides on germination of post-fire followers. Methodological differences between the study by Preston et al. (2004) and previous work are also problematic, such as using NO-donors in solution versus the use of direct application of various nitrogen oxides in the gaseous phase. A closer review of these studies, with the proper understanding of nitrogen oxide chemistry, and interpretations of the available literature, would lead to the conclusion that, contrary to the authors' assertions, the Preston et al. (2004) study supports, rather than refutes, earlier findings by Keeley and Fotheringham (1997, 1998a, b, 2000). ?? CAB International 2005.

Meta-analysis of the Alpha/Beta Ratio for Prostate Cancer in the Presence of an Overall Time Factor: Bad News, Good News, or No News?  

SciTech Connect

Purpose: To present a novel method for meta-analysis of the fractionation sensitivity of tumors as applied to prostate cancer in the presence of an overall time factor. Methods and Materials: A systematic search for radiation dose-fractionation trials in prostate cancer was performed using PubMed and by manual search. Published trials comparing standard fractionated external beam radiation therapy with alternative fractionation were eligible. For each trial the {alpha}/{beta} ratio and its 95% confidence interval (CI) were extracted, and the data were synthesized with each study weighted by the inverse variance. An overall time factor was included in the analysis, and its influence on {alpha}/{beta} was investigated. Results: Five studies involving 1965 patients were included in the meta-analysis of {alpha}/{beta}. The synthesized {alpha}/{beta} assuming no effect of overall treatment time was -0.07 Gy (95% CI -0.73-0.59), which was increased to 0.47 Gy (95% CI -0.55-1.50) if a single highly weighted study was excluded. In a separate analysis, 2 studies based on 10,808 patients in total allowed extraction of a synthesized estimate of a time factor of 0.31 Gy/d (95% CI 0.20-0.42). The time factor increased the {alpha}/{beta} estimate to 0.58 Gy (95% CI -0.53-1.69)/1.93 Gy (95% CI -0.27-4.14) with/without the heavily weighted study. An analysis of the uncertainty of the {alpha}/{beta} estimate showed a loss of information when the hypofractionated arm was underdosed compared with the normo-fractionated arm. Conclusions: The current external beam fractionation studies are consistent with a very low {alpha}/{beta} ratio for prostate cancer, although the CIs include {alpha}/{beta} ratios up to 4.14 Gy in the presence of a time factor. Details of the dose fractionation in the 2 trial arms have critical influence on the information that can be extracted from a study. Studies with unfortunate designs will supply little or no information about {alpha}/{beta} regardless of the number of subjects enrolled.

Contact: Releasing the news  

NASA Astrophysics Data System (ADS)

The problem of mass behavior after man's future contacts with other intelligences in the universe is not only a challenge for social scientists and political leaders all over the world, but also a cultural time bomb as well. In fact, since the impact of CETI (Contact with Extraterrestrial Intelligence) on human civilization, with its different cultures, might cause a serious socio-anthropological shock, a common and predetermined worldwide strategy is necessary in releasing the news after the contact, in order to keep possible manifestations of fear, panic and hysteria under control. An analysis of past studies in this field and of parallel historical situations as analogs suggests a definite "authority crisis" in the public as a direct consequence of an unexpected release of the news, involving a devastating "chain reaction" process (from both the psychological and sociological viewpoints) of anomie and maybe the collapse of today's society. The only way to prevent all this is to prepare the world's public opinion concerning contact before releasing the news, and to develop a long-term strategy through the combined efforts of scientists, political leaders, intelligence agencies and the mass media, in order to create the cultural conditions in which a confrontation with ETI won't affect mankind in a traumatic way. Definite roles and tasks in this multi-level model are suggested.

64Cu-NO2A-RGD-Glu-6-Ahx-BBN(7-14)NH2: a heterodimeric targeting vector for positron emission tomography imaging of prostate cancer  

PubMed Central

Introduction The present study describes the design and development of a new heterodimeric RGD-bombesin (BBN) agonist peptide ligand for dual receptor targeting of the form 64Cu-NO2A-RGD-Glu-6-Ahx-BBN(7-14)NH2 in which Cu-64=a positron emitting radiometal; NO2A=1,4,7-triazacyclononane-1,4-diacetic acid; Glu=glutamic acid; 6-Ahx=6-aminohexanoic acid; RGD=the amino acid sequence [Arg-Gly-Asp], a nonregulatory peptide that has been used extensively to target ?v?3 receptors up-regulated on tumor cells and neovasculature; and BBN(7-14)NH2=Gln-Trp-Ala-Val-Gly-His-Leu-Met-NH2, an agonist analogue of bombesin peptide for specific targeting of the gastrin-releasing peptide receptor (GRPr). Methods RGD-Glu-6-Ahx-BBN(7-14)NH2 was manually coupled with NOTA (1,4,7-triazacyclononane-1,4,7-triacetic acid), and the resulting conjugate was labeled with 64Cu to yield 64Cu-NO2A-RGD-Glu-6-Ahx-BBN(7-14)NH2. Purification was achieved via reversed-phase high-performance liquid chromatography and characterization confirmed by electrospray ionization–mass spectrometry. Results Competitive displacement binding assays displayed single-digit nanomolar IC50 values showing very high binding affinities toward the GRPr for the new heterodimeric peptide analogues. In vivo biodistribution studies showed high uptake and retention of tumor-associated radioactivity in PC-3 tumor-bearing rodent models with little accumulation and retention in nontarget tissues. The radiolabeled conjugate also exhibited rapid urinary excretion and high tumor-to-background ratios. Micro-positron emission tomography (microPET) molecular imaging investigations produced high-quality, high-contrast images in PC-3 tumor-bearing mice 15 h postinjection. Conclusions Based on microPET imaging experiments that show high-quality, high-contrast images with virtually no residual gastrointestinal radioactivity, this new heterodimeric RGD-BBN conjugate can be considered as a promising PET tracer candidate for the diagnosis of GRPr-positive tumors in human patients.

Tech News Collection  

NSDL National Science Digital Library

The Illinois Institute of Technology (IIT) started life in 1893 as the Armour Institute, courtesy of funding from Philip Danforth, Sr. who gave $1 million to start a school that would offer courses in engineering, chemistry, architecture, and library science. In 1940, the school merged with the Lewis Institute and received its current name. This intriguing digital collection offers a look into the school's history via the Technology News, which has been the student newspaper since 1928. Visitors can browse past issues from that year up to the current day. The Features area is quite interesting, as it includes direct links to April Fools issues and topical coverage of swine flu outbreaks in 1976 and 2009. The April Fools issue from 1942 is quite a pip, as it includes articles titled "Surrealist Ginks Gab" and "Tennis Toddlers Tersely Terrorize Tirty-Tird Toughs."

Radiation hormesis: the good, the bad, and the ugly.  

PubMed

Three aspects of hormesis with low doses of ionizing radiation are presented: the good, the bad, and the ugly. The good is acceptance by France, Japan, and China of the thousands of studies showing stimulation and/or benefit, with no harm, from low dose irradiation. This includes thousands of people who live in good health with high background radiation. The bad is the nonacceptance of radiation hormesis by the U. S. and most other governments; their linear no threshold (LNT) concept promulgates fear of all radiation and produces laws which have no basis in mammalian physiology. The LNT concept leads to poor health, unreasonable medicine and oppressed industries. The ugly is decades of deception by medical and radiation committees which refuse to consider valid evidence of radiation hormesis in cancer, other diseases, and health. Specific examples are provided for the good, the bad, and the ugly in radiation hormesis. PMID:18648595

Of course, this wasn't recent by human standards - the Eocene epoch during which these temperatures were the norm occurred about 55 to 48 million years ago. However, this finding may provide insight into how Earth's climate responds to variable levels of atmospheric carbon dioxide. In addition, it allows us to imagine a world very different from the one we know: one in which palm trees flourished at latitudes that today reach summer highs of about 8 C and sink to lows of -50 C.The first link takes visitors to a blog entry outlining some of the article's discoveries, including detailed descriptions of the ecosystem.

Risk factors for a bad split during sagittal split osteotomy.  

PubMed

One of the operative complications during sagittal split osteotomy (SSO) in orthognatic surgery is a bad split, meaning an undesired fracture of the mandible during osteotomy. The aim of this study was to find out if there is a relation between the occurrence of bad splits during SSO and the presence of third molars, the patient's age, or the surgeon's experience. Clinical notes of 110 consecutive patients who had had a total of 220 SSOs using the Obwegeser/Dal Pont technique were evaluated and divided into three groups: 1 missing third molar (n=168); 2 retained or impacted third molar that was removed during the SSO (n=23); and 3 third molar left in place during SSO (n=29). There were a total of 12 (6%) bad splits. 9 (5%) in group 1, two (9%) in group 2, and one (3%) in group 3. There were no significant differences between groups 1-3, in particular the surgeon's qualification had no influence on the incidence. Older patients seemed more at risk of a bad split than younger ones. PMID:18063456

Hollywood Science: Good for Hollywood, Bad for Science?  

NASA Astrophysics Data System (ADS)

Like it or not, most science depicted in feature films is in the form of science fiction. This isn't likely to change any time soon, if only because science fiction films are huge moneymakers for Hollywood. But beyond that, these films are a powerful cultural force. They reach millions as they depict scientific ideas from DNA and cloning to space science, whether correctly or incorrectly; reflect contemporary issues of science and society like climate change, nuclear power and biowarfare; inspire young people to become scientists; and provide defining images -- or stereotypes -- of scientists for the majority of people who've never met a real one. Certainly, most scientists feel that screen depictions of science and scientists are badly distorted. Many are, but not always. In this talk, based on my book Hollywood Science [1], I'll show examples of good and bad screen treatments of science, scientists, and their impact on society. I'll also discuss efforts to improve how science is treated in film and ways to use even bad movie science to convey real science.

Pigeons can discriminate "good" and "bad" paintings by children.  

PubMed

Humans have the unique ability to create art, but non-human animals may be able to discriminate "good" art from "bad" art. In this study, I investigated whether pigeons could be trained to discriminate between paintings that had been judged by humans as either "bad" or "good". To do this, adult human observers first classified several children's paintings as either "good" (beautiful) or "bad" (ugly). Using operant conditioning procedures, pigeons were then reinforced for pecking at "good" paintings. After the pigeons learned the discrimination task, they were presented with novel pictures of both "good" and "bad" children's paintings to test whether they had successfully learned to discriminate between these two stimulus categories. The results showed that pigeons could discriminate novel "good" and "bad" paintings. Then, to determine which cues the subjects used for the discrimination, I conducted tests of the stimuli when the paintings were of reduced size or grayscale. In addition, I tested their ability to discriminate when the painting stimuli were mosaic and partial occluded. The pigeons maintained discrimination performance when the paintings were reduced in size. However, discrimination performance decreased when stimuli were presented as grayscale images or when a mosaic effect was applied to the original stimuli in order to disrupt spatial frequency. Thus, the pigeons used both color and pattern cues for their discrimination. The partial occlusion did not disrupt the discriminative behavior suggesting that the pigeons did not attend to particular parts, namely upper, lower, left or right half, of the paintings. These results suggest that the pigeons are capable of learning the concept of a stimulus class that humans name "good" pictures. The second experiment showed that pigeons learned to discriminate watercolor paintings from pastel paintings. The subjects showed generalization to novel paintings. Then, as the first experiment, size reduction test, grayscale test, mosaic processing test and partial occlusion test were carried out. The results suggest that the pigeons used both color and pattern cues for the discrimination and show that non-human animals, such as pigeons, can be trained to discriminate abstract visual stimuli, such as pictures and may also have the ability to learn the concept of "beauty" as defined by humans.

AIDS, conflict and the media in Africa: risks in reporting bad data badly  

PubMed Central

Background Conflict, poverty and HIV disproportionately affect people in sub-Saharan Africa. The manner in which governments, national and international organisations and the media report on the HIV epidemic in situations of conflict, post-conflict and reconstruction can have unintended and negative consequences for those affected populations. The media in particular has a huge influence on how the world observes and reacts to the HIV epidemic among conflict-affected and displaced populations. Discussion Three case studies focused on Sudan, Uganda and Guinea describe what the media reported and why the reports were incomplete, misleading or incorrect. The exploration of possible ways to ensure that the media do not unwittingly inflame delicate and complicated situations of HIV among conflict-affected and displaced populations is then undertaken using epidemiological and journalistic principles. The discussion is divided into four sections: 1) Avoid stigmatising statements and ensure a balanced view; 2) Avoid accurate but misleading statements; 3) Avoid inaccurate statements by clearly stating sources and verifying their credibility; and 4) Do not repeat data and conclusions from other news sources without checking their accuracy. The aim of this manuscript is to stimulate awareness and debate among persons and organisations working on HIV/AIDS as well as the media in order to improve dialogue and ultimately to reduce stigma and discrimination amongst an already vulnerable group – conflict-affected and displaced persons. Summary The media and humanitarian organisations have published misleading and inaccurate HIV data and statements on conflict-affected and displaced populations in Sudan, Uganda and Guinea. Given the unique characteristics of the HIV epidemic and conflict-affected and displaced populations, the media have a special obligation to report in a balanced and non-discriminatory manner that may go beyond the accepted standards of journalism. The media may wish to have the HIV data and their interpretation reviewed by technical experts before going to press. Specific training for reporters and editors regarding ethical issues and basic epidemiological methods may help them to better understand the complexity of the situation and report more accurately; similar training for media watch groups and human rights organisations may improve the monitoring of such situations and possibly reduce misreporting and subsequent discrimination. More rigorous HIV biological and behavioural surveillance should be undertaken in situations of conflict and displacement and humanitarian guidelines should be integrated with guidance on media relations and reporting responsibilities of humanitarian agencies. Finally, humanitarian agencies must ensure the data they release are sound and that any biases are clearly stated. Improved communication with the media will help to ensure more accurate reporting and interpretation.

Supplementary Materials The number of supplementary materials that accompany print articles has grown and also become more varied. The new guidelines for lab experiments call for supplementary materials in most cases, so that the actual materials used in lab can be made available. The From Past Issues column edited by Kathryn Williams and many of the technology columns frequently have supplements for JCE Online. An especially interesting supplement that we would like to call to the attention of readers is a collection of videos from the E. O. Lawrence Berkeley National Laboratory, based on interviews with nuclear chemists who have discovered and studied the heaviest elements. These movies accompany the Viewpoints article, "Chemistry of the Heaviest Elements-One Atom at a Time" by Darleane C. Hoffman and Diana M. Lee. The titles of the movies are listed below; illustrative stills are shown at the bottom of the page. Researchers involved with the segments about Lawrencium include Robert Silva, Torbjorn Sikkeland, Matti Nurmia, Robert Latimer, and Albert Ghiorso, all of whom are from the Lawrence Berkeley Laboratory.

People: Glenn Seaborg Glenn Seaborg, frequent contributor and faithful supporter of this Journal, died February 25, 1999, at his home in Lafayette, California, at the age of 86. At the Fall 1998 ACS Meeting in Boston he suffered a serious fall following a stroke, from which he never recovered. One of his last photographs, taken the previous day at a Journal luncheon, appears on page 1360 of the November 1998 issue. His commentary on his long career in chemistry and education appears on page 1520 of the December 1998 issue. Seaborg was a Nobel laureate, discoverer of elements, scientific advisor to presidents, former chancellor of the University of California, former chairman of the Atomic Energy Commission, chairman of the steering committee of the CHEM Study project, founder of Lawrence Hall of Science, , the list goes on and on. He was at the same time a passionate supporter of education. Seaborg published fourteen articles in the Journal between 1951 and 1998. He was interviewed in 1975 by David Ridgway as part of the Impact series (JCE 1975, 52, 70), and that interview is highly recommended reading (see supplement to this article). He received the 1994 ACS George C. Pimentel Award in Chemical Education; his award address was published in the ACS Division of Chemical Education's CHED Newsletter, Fall 1995. Memorial articles with details of his life and his scientific contributions have appeared in The New York Times (Saturday, February 27, 1999, page 1) and Chemical & Engineering News (March 8, 1999, page 29). But there is also the spirit of the man, what he believed in, what he tried to do, what he hoped he had accomplished. A sense of that can be gained from the excerpts that are reprinted below, taken first from the Impact interview and then from the award address. Ridgway: On reflection, now, out of your many contributions to chemistry, is there one that you feel has had more of an impact than others? Seaborg: The discovery of plutonium would answer that question. The impact th

Restoration of badly broken, endodontically treated posterior teeth  

PubMed Central

It is generally agreed that the successful treatment of a badly broken tooth with pulpal disease depends not only on good endodontic therapy, but also on good prosthetic reconstruction of the tooth after the endodontic therapy is complete. Often, we come across an endodontically treated tooth with little or no clinical crown in routine clinical cases. In such cases, additional retention and support of the restoration are difficult to achieve. Two case reports are discussed here where structurally compromised, endodontically treated, posterior teeth were restored using the Richmond crown in the first case, and by the use of two nonparallel cast posts in the second case.

[Historical study on traditional Chinese formulations and crude drugs used for bad breath].  

PubMed

Bad breath is a topic of general interest. In this study, the treatment for bad breath in traditional Chinese medicine was reviewed with a special focus on pathologic diagnosis and crude drug prescriptions. It was shown that bad breath developed based on both systemic and local diseases. Some systemic conditions, including nasal, paranasal, pulmonary and digestive diseases, are considered to cause bad breath. The morbid state of a patient with bad breath has been recognized as being based on "heat syndrome" and "Qi-stagnation syndrome." Bad breath based on "heat syndrome" is manifested as thirst and ulceration of the oral cavity, and has been treated with crude drugs such as Coptis rhizome, Scutellaria root and gypsum. One case study reported that bad breath resulting from a dry mouth was treated with byakkokaninjinto, a Kampo formulation containing gypsum. "Qi" is considered to be the vital energy of all life forms including for the functioning of organs and mental and emotional activity. "Qi-stagnation syndrom," referring to the dysfunction of organs, is manifested as psychosomatic symptoms such as irritability, a flushed face and restlessness. Bad breath based on "Qi-stagnation syndrome" has been treated with crude drugs such as Cnidium rhizome, clove and cinnamon bark. Modern dental and medical treatment both accept the participation of psychogenic agents in the development of bad breath. Bad breath also develops based on periodontal and oral diseases. This type of bad breath has been treated with mouth-wash (collutorium) containing Asiasarum root, Angelica dahurica root and Cnidium rhizome. This historical evidence regarding crude drug prescriptions contributes to the development of mouth care products for preventing and treating bad breath. PMID:22164685

Reversing one's fortune by pushing away bad luck.  

PubMed

Across cultures, people try to "undo" bad luck with superstitious rituals such as knocking on wood, spitting, or throwing salt. We suggest that these rituals reduce the perceived likelihood of anticipated negative outcomes because they involve avoidant actions that exert force away from one's representation of self, which simulates the experience of pushing away bad luck. Five experiments test this hypothesis by having participants tempt fate and then engage in avoidant actions that are either superstitious (Experiment 1, knocking on wood) or nonsuperstitious (Experiments 2-5, throwing a ball). We find that participants who knock down (away from themselves) or throw a ball think that a jinxed negative outcome is less likely than participants who knock up (toward themselves) or hold a ball. Experiments 3 and 4 provide evidence that after tempting fate, engaging in an avoidant action leads to less clear mental representations for the jinxed event, which, in turn, leads to lower perceived likelihoods. Finally, we demonstrate that engaging in an avoidant action-rather than creating physical distance-is critical for reversing the perceived effect of the jinx. Although superstitions are often culturally defined, the underlying psychological processes that give rise to them may be shared across cultures.

Endothelial H2O2 A Bad Guy Turning Good?  

PubMed Central

About a decade ago everyone who read, at least occasionally, the science part of the local newspapers or followed popular science broadcasts “knew” that reactive oxygen species (ROS) are dangerous. They were thought to be bad, really bad, and many looking for a healthier lifestyle took action against these nasty small molecules accused of harming lipids and proteins by taking antioxidants like vitamin E. Food industry teamed up with pharmaceutical companies and brought up functional food enriched or supplemented with trustful antioxidants in the fight against ROS, which seemed to be produced under pathological conditions with just one mission: to damage the body. Things have changed during recent years, and there is emerging evidence that ROS are not only continuously produced even in healthy individuals but also exert important physiological functions. While we are still in-between a period that provides exciting new findings on the physiology of ROS, one can already summarize our present knowledge rather accurately by citing Paracelsus’ adage of “Dosis (sola) facit venenum” (tertio defensio, 1538).

Cult film director Takashi Miike's hybrid homage Sukiyaki Western Django (2007) can be critiqued in terms of its derivative nature, its overstated affect, and its lack of psychological and thematic nuance – characteristics that are associated with ‘bad film’ genres such as the spaghetti western that Miike emulates and valorizes. The classification of texts as ‘bad film’ is often related

Reconsiderations: We Got the Wrong Gal--Rethinking the "Bad" Academic Writing of Judith Butler  

ERIC Educational Resources Information Center

It is hard to think of a writer whose work has been more prominently upheld as an example of bad academic writing than the philosopher and literary theorist Judith Butler. In 1998, Butler was awarded first prize in the annual Bad Writing Contest established by the journal "Philosophy and Literature," and early in 1999, was lampooned in an…

Detecting Bad Smells in Object Oriented Design Using Design Change Propagation Probability Matrix  

Microsoft Academic Search

Object oriented software systems are subject to frequent modifications either during development (iterative, agile software development) or software evolution. For such systems which have large number of classes, detection of design defects is a complex task. Bad smells are used to identify design defects in object oriented software design. Identification of bad smells allows us to apply appropriate refactorings to

Design, analysis, and fabrication of a really bad lens  

NASA Astrophysics Data System (ADS)

Many practical singlet lenses (with one aspheric and one planar surface) can be designed analytically without resorting to iterative optimization. "Good" lenses that precisely focus or collimate monochromatic light are covered first. Then a less important but more interesting "bad" case is discussed. An unusual application required a singlet lens whose axial caustic is an order-of-magnitude greater than its paraxial focal length. A lens with a radial spline surface was designed using the CodeV and ASAP macro languages. The near-field on-axis diffraction irradiance produced by the lens was verified using the ASAP software's beamlet decomposition/summation capability. Specification of the surface for manufacture seemed straightforward but became problematic due to limitations at the time in the software used by the computer-controlled grinding and polishing machines. Eventually the lens was manufactured successfully but only after fitting the spline to a standard radial polynomial (including odd terms).

Entropy, the Second Law and the Concept of `Bad' Energy!  

NASA Astrophysics Data System (ADS)

Thermodynamics continues to mystify and instill a sense of dread in many students. Instruction continues to follow the tortuous historic development. To counter this the author adopts a teaching method that allows the majority of students to quickly be brought up to a level where they are able to tackle a multitude of non-standard and hence non-coached problems not normally associated with conventional thermodynamic courses. The method makes extensive use of the Reynolds transport equation in conjunction with a novel derivation of entropy and the liberal use of basic accounting principles. In the definition of entropy, the confusing traditional use of the path function of heat transfer at the numerator is replaced by a `bad' energy property, that the students find more intuitive.

Can't control yourself? Monitor those bad habits.  

PubMed

What strategies can people use to control unwanted habits? Past work has focused on controlling other kinds of automatic impulses, especially temptations. The nature of habit cuing calls for certain self-control strategies. Because the slow-to-change memory trace of habits is not amenable to change or reinterpretation, successful habit control involves inhibiting the unwanted response when activated in memory. In support, two episode-sampling diary studies demonstrated that bad habits, unlike responses to temptations, were controlled most effectively through spontaneous use of vigilant monitoring (thinking "don't do it," watching carefully for slipups). No other strategy was useful in controlling strong habits, despite that stimulus control was effective at inhibiting responses to temptations. A subsequent experiment showed that vigilant monitoring aids habit control, not by changing the strength of the habit memory trace but by heightening inhibitory, cognitive control processes. The implications of these findings for behavior change interventions are discussed. PMID:20363904

Pluto behaving badly: false beliefs and their consequences.  

PubMed

We exposed college students to suggestive materials in order to lead them to believe that, as children, they had a negative experience at Disneyland involving the Pluto character. A sizable minority of subjects developed a false belief or memory that Pluto had uncomfortably licked their ear. Suggestions about a positive experience with Pluto led to even greater acceptance of a lovable ear-licking episode. False beliefs and memories had repercussions; those seduced by the bad suggestions were not willing to pay as much for a Pluto souvenir. These findings are among the first to demonstrate that false beliefs can have repercussions for people, meaning that they can influence their later thoughts, beliefs, and behaviors. PMID:19105582

Applications and benefits of "perfectly bad" optical surfaces  

NASA Astrophysics Data System (ADS)

The design and manufacture of most optical systems revolves around the use of ideal optical surfaces. "Perfect" spheres or flats are optimally combined and toleranced during the design phase, and the manufacturers attempt to get as close as possible to these perfect optical surfaces during fabrication. One reason for this stems from the inherent capabilities of the industry's oldest and most pervasive polishing tool: the full-aperture lap. The shape and motion of these tools naturally produce spherical or flat geometries. More recently, a number of new manufacturing technologies based on sub-aperture polishing tools have become available. Sub-aperture tools enable local, preferential removal: a controlled way to polish more material at some locations and less at others. Magnetorheological Finishing (MRF(R) ) is one such sup-aperture polishing technology, and when combined with an accurate measurement, can offer a precise method for converging to the perfect surface: local removal based directly on measured surface height. This capability, however, can also be leveraged in other, more creative, ways. For example, by replacing the typical surface-error measurement by a transmitted wavefront measurement of an entire low-field optical system, a hitmap can be created for one surface in the system that will perfectly compensate for errors of all the other surfaces. This paper will explore a number of examples where "perfectly bad" surfaces have been exploited in actual optical systems to improve performance, improve manufacturability, or reduce cost. In addition, we will ask the question: if making a "perfectly bad" surface was as easy as making a perfectly good one, would this capability be used more widely by the precision optics industry?

Space Shuttle Status News Conference  

NASA Technical Reports Server (NTRS)

Richard Gilbech, External Tank "Tiger Team" Lead, begins this space shuttle news conference with detailing the two major objectives of the team. The objectives include: 1) Finding the root cause of the foam loss on STS-114; and 2) Near and long term improvements for the external tank. Wayne Hale, Space Shuttle Program Manager, presents a chart to explain the external tank foam loss during STS-114. He gives a possible launch date for STS-121 after there has been a repair to the foam on the External Tank. He further discusses the changes that need to be made to the surrounding areas of the plant in New Orleans, due to Hurricane Katrina. Bill Gerstemaier, NASA Associate Administrator for Space Operations, elaborates on the testing of the external tank foam loss. The discussion ends with questions from the news media about a fix for the foam, replacement of the tiles, foam loss avoidance, the root cause of foam loss and a possible date for a new external tank to be shipped to NASA Kennedy Space Center.

The NEWS Water Cycle Climatology  

NASA Technical Reports Server (NTRS)

NASA's Energy and Water Cycle Study (NEWS) program fosters collaborative research towards improved quantification and prediction of water and energy cycle consequences of climate change. In order to measure change, it is first necessary to describe current conditions. The goal of the first phase of the NEWS Water and Energy Cycle Climatology project was to develop "state of the global water cycle" and "state of the global energy cycle" assessments based on data from modern ground and space based observing systems and data integrating models. The project was a multi-institutional collaboration with more than 20 active contributors. This presentation will describe the results of the water cycle component of the first phase of the project, which include seasonal (monthly) climatologies of water fluxes over land, ocean, and atmosphere at continental and ocean basin scales. The requirement of closure of the water budget (i.e., mass conservation) at various scales was exploited to constrain the flux estimates via an optimization approach that will also be described. Further, error assessments were included with the input datasets, and we examine these in relation to inferred uncertainty in the optimized flux estimates in order to gauge our current ability to close the water budget within an expected uncertainty range.

Cancer News Coverage and Information Seeking  

PubMed Central

The shift toward viewing patients as active consumers of health information raises questions about whether individuals respond to health news by seeking additional information. This study examines the relationship between cancer news coverage and information seeking using a national survey of adults aged 18 years and older. A Lexis-Nexis database search term was used to identify Associated Press (AP) news articles about cancer released between October 21, 2002, and April 13, 2003. We merged these data to the Health Information National Trends Survey (HINTS), a telephone survey of 6,369 adults, by date of interview. Logistic regression models assessed the relationship between cancer news coverage and information seeking. Overall, we observed a marginally significant positive relationship between cancer news coverage and information seeking (p < 0.07). Interaction terms revealed that the relationship was apparent only among respondents who paid close attention to health news (p < 0.01) and among those with a family history of cancer (p < 0.05). Results suggest that a notable segment of the population actively responds to periods of elevated cancer news coverage by seeking additional information, but they raise concerns about the potential for widened gaps in cancer knowledge and behavior between large segments of the population in the future.

Evaluation of Combined 177Lu-DOTA-8-AOC-BBN(7-14)NH2 GRP Receptor Targeted Radiotherapy and Chemotherapy in PC-3 Human Prostate Tumor Cell Xenografted SCID Mice  

PubMed Central

The focus of this study was to evaluate the therapeutic benefit of combined gastrin releasing peptide (GRP) receptor targeted-radiotherapy (TRT) with chemotherapy using the PC-3 xenograft SCID mouse model. 177Lu-DOTA-8-AOC-BBN(7-14)NH2 is a radiotherapeutic peptide which specifically targets the gastrin releasing peptide receptor over-expressed on primary and metastatic prostate cancer. The chemotherapeutic agents docetaxel and estramustine, were administered as single agents or in combination with the receptor targeted radiotherapeutic agent. Combination receptor TRT/chemotherapy studies were begun 21 days post xenografting and were conducted as multiple dose trials. The GRP receptor TRT agent was administered every 14 days and single and combination chemotherapy dose regimens were given weekly. Tumor size, body weight, and body condition score were evaluated twice weekly and a hematology profile once weekly. Therapy study tumor volumes were evaluated by way of a repeated measures analysis of variance. Tumor volume measurements at 12 days post dose administration demonstrated a statistically significant (two-tailed p value < 0.05) tumor growth suppression in all experimental groups receiving GRP receptor targeted radiotherapy, when compared to the control group. The two combined GRP receptor TRT/chemotherapy treatment groups demonstrated the greatest tumor growth suppression of all treatment groups. In comparing the two combined GRP receptor TRT/chemotherapy groups to the GRP receptor TRT alone group, a statistically significant difference was demonstrated for the combined groups by day 30, post dose administration. These data demonstrate that GRP receptor targeted radiation therapy using 177Lu-DOTA-8-AOC-BBN(7-14)NH2, employed either alone, or in combination with conventional chemotherapy can suppress the growth of androgen independent prostate cancer.

Good days and bad days in dementia: a qualitative chart review of variable symptom expression.  

PubMed

ABSTRACT Background: Despite its importance in the lived experience of dementia, symptom fluctuation has been little studied outside Lewy body dementia. We aimed to characterize symptom fluctuation in patients with Alzheimer's disease (AD) and mixed dementia. Methods: A qualitative analysis of health records that included notations on good days and bad days yielded 52 community-dwelling patients (women, n = 30; aged 39-91 years; mild dementia, n = 26, chiefly AD, n = 36). Results: Good days/bad days were most often described as changes in the same core set of symptoms (e.g. less/more verbal repetition). In other cases, only good or only bad days were described (e.g. no bad days, better sense of humor on good days). Good days were typically associated with improved global cognition, function, interest, and initiation. Bad days were associated with frequent verbal repetition, poor memory, increased agitation and other disruptive behaviors. Conclusions: Clinically important variability in symptoms appears common in AD and mixed dementia. Even so, what makes a day "good" is not simply more (or less) of what makes a day "bad". Further investigation of the factors that facilitate or encourage good days and mitigate bad days may help improve quality of life for patients and caregivers. PMID:24565377

Collective bads: The case of low-level radioactive waste compacts  

SciTech Connect

In low-level radioactive waste (LLW) compact development, policy gridlock and intergovernmental conflict between states has been the norm. In addition to the not-in-my-backyard (NIMBY) phenomenon, LLW compacts must content with myriad political and ethical dilemmas endemic to a particular collective bad. This paper characterizes the epistemology of collective bads, and reviews how LLW compacts deal with such bads. In addition, using data from survey questionnaires and interviews, this paper assesses the cooperative nature of LLW compacts in terms of their levels of regional autonomy, regional efficacy, allocation of costs and benefits, and their technocentric orientation.

Ionizing Radiation: The Good, the Bad, and the Ugly  

PubMed Central

Skin changes from ionizing radiation have been scientifically documented since 1902 (Hymes et al., 2006). Ionizing radiation is a widely accepted form of treatment for various types of cancer. Despite the technological advances, radiation skin injury remains a significant problem. This injury, often referred to as radiation dermatitis, occurs in about 95% of patients receiving radiation therapy for cancer and ranges in severity from mild erythema to moist desquamation and ulceration (McQuestion, 2011; Salvo et al., 2010). Ionizing radiation is not only a concern for cancer patients, but also a public health concern due to the potential for and reality of a nuclear and/or radiological event. Recently, the United States has increased efforts to develop medical countermeasures to protect against radiation toxicities from acts of bioterrorism, as well as cancer treatment. Management of radiation dermatitis would improve the therapeutic benefit of radiation therapy for cancer and potentially the mortality expected in any “dirty bomb” attack (Benderitter et al., 2010; Muller and Meineke, 2010). Currently, there is no effective treatment to prevent or mitigate radiation skin injury. This review summarizes “the good, the bad and the ugly” of current and evolving knowledge regarding mechanisms of and treatments for radiation skin injury.

Since 2007 I have been using NYTimes current News articles rich in graphics and physics variables for developing edited one page web (http://CisePhysics.homestead.com/files/NYT.htm) physics questions based on current events in the news. The NYTimes home page listed above contains currently ten pages with about 40 one page current edited News related physics articles per page containing: rich graphics, graphic editions by the author, edited articles, introduction to a question, questions, and answers. I use these web pages to introduce new physics concepts to students with current applications of concepts in the news. I also use these one page physics applications as pop quizzes and extra credit for students. As news happens(e.g. the 2010 Vancouver Olympics) I find the physics applications in the NYTimes articles and generate applications and questions. These new one page applications with questions are added to the home page: http://CisePhysics.homestead.com/files/NYT.htm The newest pages start with page 10 and work back in time to 9, 8, etc. The ten web pages with about 40 news articles per page are arranged in the traditional manner: vectors, kinematics, projectiles, Newton, Work & Energy, properties of matter, fluids, temperature, heat, waves, and sound. This site is listed as a resource in AAPT's Compadre site.

BAD-Dependent Regulation of Fuel Metabolism and KATP Channel Activity Confers Resistance to Epileptic Seizures  

PubMed Central

Summary Neuronal excitation can be substantially modulated by alterations in metabolism, as evident from the anticonvulsant effect of diets that reduce glucose utilization and promote ketone body metabolism. We provide genetic evidence that BAD, a protein with dual functions in apoptosis and glucose metabolism, imparts reciprocal effects on metabolism of glucose and ketone bodies in brain cells. These effects involve phospho-regulation of BAD and are independent of its apoptotic function. BAD modifications that reduce glucose metabolism produce a marked increase in the activity of metabolically sensitive KATP channels in neurons, as well as resistance to behavioral and electrographic seizures in vivo. Seizure resistance is reversed by genetic ablation of the KATP channel, implicating the BAD-KATP axis in metabolic control of neuronal excitation and seizure responses.

Fragrance in rice (Oryza sativa), known to be primarily associated with grain 2-Acetyl-1-Pyrroline (2AP) concentration, is a highly valued trait. It has previously been determined that a non-functional betaine aldehyde dehydrogenase (BAD2) encoding gene homologue is responsible for fragrance in rice. It is hypothesized that in non-fragrant rice BAD2 catalyses the breakdown of a precursor to 2AP while the presence

Porphyromonas gingivalis infection sequesters pro-apoptotic Bad through Akt in primary gingival epithelial cells  

PubMed Central

SUMMARY Porphyromonas gingivalis, a self-limiting oral pathogen, can colonize and replicate in gingival epithelial cells (GECs). P. gingivalis-infected GECs are protected from mitochondrion-dependent apoptosis, partially through activation of phosphatidyl inositol 3-kinase/Akt signaling. Biochemical events associated with P. gingivalisinduced inhibition of apoptosis include the blocking of mitochondrial membrane permeability and cytochrome-c release. We studied functional importance of Akt and the status of associated key mitochondrial molecules, pro-apoptotic Bad and caspase-9, during infection of GECs. We found that P. gingivalis infection caused significant phosphorylation of Bad progressively, while messenger RNA levels for Bad slowly decreased. Fluorescence microscopy showed translocation of the mitochondrial Bad to the cytosol post-infection. Conversely, P. gingivalis lost the ability to promote phosphorylation and translocation of Bad in Akt-deficient GECs. Caspase-9 activation induced by a chemical inducer of apoptosis was significantly inhibited by infection over time. However, Akt depletion by small interfering RNA did not reverse inhibition of caspase-9 activation by infection. Hence, P. gingivalis inactivates pro-apoptotic Bad through Akt. The inhibition of caspase-9 activation appears to be independent of Akt. Overall, our findings suggest that Akt is a key component of anti-apoptotic pathways stimulated by P. gingivalis. The P. gingivalis uses other mitochondrial pathways to protect host cells from cell-death and to ensure its survival in gingival epithelium.

Functional and radiographic long-term results after bad split in orthognathic surgery.  

PubMed

Bilateral sagittal split osteotomy (BSSO) is a standard procedure in orthognathic surgery. The aim of the present study was to perform a matched pair analysis (bad sagittal split versus regular sagittal split) regarding the functional and radiographic long-term results after BSSO. Of 110 cases of mandibular hypoplasy treated with BSSO, 7 cases of bad sagittal splits (Group A) were selected, clinically examined and matched to 7 cases where no bad split occurred (Group B). The Research Diagnostic Criteria for Temporo Mandibular Disorders (RDC/TMD), condylar morphology scale (CMS) and ramus height measurements using orthopantomograms were carried out in the follow-up period to observe the clinical and functional status and condylar resorbtion or remodelling. The mean follow-up time was 28.6 months. The RDC/TMD examination did not show a higher incidence of temporomandibular dysfunction, including pain or clicking in the bad split group. Patients without a bad split showed statistically significant (p<0.05) better mouth opening. The CMS measurements were comparable in both groups. When compared with regular splits, bad splits, if treated in an appropriate manner, have a good chance of functional success, although, some mandibular movements can be compromised. PMID:18515045

The Caudate Signals Bad Reputation during Trust Decisions  

PubMed Central

The ability to initiate and sustain trust is critical to health and well-being. Willingness to trust is in part determined by the reputation of the putative trustee, gained via direct interactions or indirectly through word of mouth. Few studies have examined how the reputation of others is instantiated in the brain during trust decisions. Here we use an event-related functional MRI (fMRI) design to examine what neural signals correspond to experimentally manipulated reputations acquired in direct interactions during trust decisions. We hypothesized that the caudate (dorsal striatum) and putamen (ventral striatum) and amygdala would signal differential reputations during decision-making. Twenty-nine healthy adults underwent fMRI scanning while completing an iterated Trust Game as trusters with three fictive trustee partners who had different tendencies to reciprocate (i.e., likelihood of rewarding the truster), which were learned over multiple exchanges with real-time feedback. We show that the caudate (both left and right) signals reputation during trust decisions, such that caudate is more active to partners with two types of “bad” reputations, either indifferent partners (who reciprocate 50% of the time) or unfair partners (who reciprocate 25% of the time), than to those with “good” reputations (who reciprocate 75% of the time). Further, individual differences in caudate activity related to biases in trusting behavior in the most uncertain situation, i.e. when facing an indifferent partner. We also report on other areas that were activated by reputation at p < 0.05 whole brain corrected. Our findings suggest that the caudate is involved in signaling and integrating reputations gained through experience into trust decisions, demonstrating a neural basis for this key social process.

Measuring the Interestingness of News Articles  

SciTech Connect

An explosive growth of online news has taken place. Users are inundated with thousands of news articles, only some of which are interesting. A system to filter out uninteresting articles would aid users that need to read and analyze many articles daily, such as financial analysts and government officials. The most obvious approach for reducing the amount of information overload is to learn keywords of interest for a user (Carreira et al., 2004). Although filtering articles based on keywords removes many irrelevant articles, there are still many uninteresting articles that are highly relevant to keyword searches. A relevant article may not be interesting for various reasons, such as the article's age or if it discusses an event that the user has already read about in other articles. Although it has been shown that collaborative filtering can aid in personalized recommendation systems (Wang et al., 2006), a large number of users is needed. In a limited user environment, such as a small group of analysts monitoring news events, collaborative filtering would be ineffective. The definition of what makes an article interesting--or its 'interestingness'--varies from user to user and is continually evolving, calling for adaptable user personalization. Furthermore, due to the nature of news, most articles are uninteresting since many are similar or report events outside the scope of an individual's concerns. There has been much work in news recommendation systems, but none have yet addressed the question of what makes an article interesting.

Molecular modeling of human BAD and its interaction with PKAc or PP1c.  

PubMed

To build up the structure of human BAD (Bcl-2 antagonist of cell death), subsequently combined with PKAc or PP1c (protein phosphatase 1), to investigate the interaction relationship between BAD and its kinase/PTPese at the molecular level. Additionally, it is concerned with the search for all optimal positions and orientations of a set of amino acid residues of BAD, while its binding sites include N-termini (Glu19, Ala27, and Ser34-Lys35), BH3-located helical domain (Arg98-Lys126), and C-termini (Trp154-Ser163 and Ser167-Gln168). The related sites of PKAc are mainly assembled in C-terminal alpha/beta-domain of PKAc, which comprises the KTL motif (47-49), Glu203 residue, a helical region (Asp241-Arg256), and the span from 328 to 333; while the interaction sites with BAD converge at C-terminal beta-domain of PP1c, which includes the DEK motif (166-168), the stretch from 179 to 197 including a helix (Glu184-Arg188), Glu230-Asp242 segment containing Val232-His237 helix, and Glu287-Leu289 loop. In conclusion, analysis of the complex between BAD and PKAc or PP1c provides a novel viewpoint on the structural origins of molecular recognition. And the complex models suggest that BH3 domain of BAD interact with PKAc or PP1c by electrostatic, van der Waals contacts, hydrogen bond and salt bridge. This is helpful for our development and research of some new drugs, especially mimetic BH3 peptides and inspires scientists with BAD complex and molecular mechanism of its integrating glycolysis and apoptosis.

Photographs cause false memories for the news.  

PubMed

What is the effect on memory when seemingly innocuous photos accompany false reports of the news? We asked people to read news headlines of world events, some of which were false. Half the headlines appeared with photographs that were tangentially related to the event; others were presented without photographs. People saw each headline only once, and indicated whether they remembered the event, knew about it, or neither. Photos led people to immediately and confidently remember false news events. Drawing on the Source Monitoring Framework (Johnson, Hashtroudi, & Lindsay, 1993), we suggest that people often relied on familiarity and other heuristic processes when making their judgments and thus experienced effects of the photos as evidence of memory for the headlines.

Tipping news in information accumulation system  

NASA Astrophysics Data System (ADS)

As a continuous opinion dynamics model, the information accumulation system (IAS) includes three basic mechanisms of the news, the inheritance and the diffusion as contributing to the information accumulation process of a system. A system is composed of agents who diffuse information through internal interaction, while each of them has incomplete memory or inheritance rate. The news comes from external sources of information, such as mass media. Previously the model IAS was studied only for the small news problems. In this study, a tipping news problem is considered. A key question of the problem is: what is the minimum strength of advertisement that can tip the minority opinion to a majority one? Dynamics of the IAS is briefly revisited with a special interest on nonlinear behavior of the model. In particular, it is shown that a discrete map of the IAS for a single color problem can be transformed into a logistic map, from which the dynamics of the IAS can be better understood. To show the applicability of the IAS model, the result is applied to explain the concept of the critical population size, which claims that there is a minimum population size for a social knowledge system to be continuously inherited without being lost. And critical size of the tipping news is found analytically in terms of IAS parameters. Some of the key results from the present study are compared in detail with the results from the Brownian particle model, which is believed to be the most similar model to the IAS. The concept of tipping news is used to show that a traditional society can tip at an exceptionally low inter-community exposure. Finally, the result was applied to the language competition problem.

Measuring nightmare and bad dream frequency: impact of retrospective and prospective instruments.  

PubMed

Studies on nightmare frequency have yielded inconsistent results. We compared the frequency of nightmares and bad dreams obtained with retrospective methods (annual and monthly estimates) and with two types of prospective measures (narrative and checklist logs). Four hundred and eleven participants completed retrospective estimates of nightmare and bad dream frequency and recorded their dreams in either narrative or checklist logs for 2-5 weeks. When measured prospectively with narrative logs, nightmare frequency was marginally higher than the 1-year estimate (P = 0.057) but not significantly different from the 1-month estimate (P > 0.05). Prospective bad dream frequency was significantly greater than the two retrospective estimates (ps < 0.0005). There were no significant differences in the frequency of nightmares and bad dreams reported prospectively with narrative versus checklist logs (ps > 0.05). However, checklist logs yielded a significantly greater number of everyday dreams per week (P < 0.0001). Taken together, the results provide partial support for the idea that when compared to daily logs, retrospective self-reports significantly underestimate current nightmare and bad dream frequency. Prospective studies of dream recall and nightmare frequency should take into account the type of log used, its duration, and the participants' level of motivation over time. PMID:18482103

Thus, a specific structural video such as news video is parsed, because it is included both temporal and spatial characteristics that the news event with an anchor-person is iteratively appeared, a news icon and a caption are involved in some frame, respectively. To extract automatically the key frames by using the structured knowledge of news, the model used in this paper is consisted of the news event segmentation, caption recognition and search browser module. The following are three main modules represented in this paper: (1) The news event segmentation module (NESM) for both the recognition and the division of an anchor-person shot. (2) The caption recognition module (CRM) for the detection of the caption-frames in a news event, the extraction of their caption region in the frame by using split-merge method, and the recognition of the region as a text with OCR software. 3) The search browser module (SBM) for the display of the list of news events and news captions, which are included in selected news event. However, the SBM can be caused various searching mechanisms.

Cohesiveness in Financial News and its Relation to Market Volatility  

PubMed Central

Motivated by recent financial crises, significant research efforts have been put into studying contagion effects and herding behaviour in financial markets. Much less has been said regarding the influence of financial news on financial markets. We propose a novel measure of collective behaviour based on financial news on the Web, the News Cohesiveness Index (NCI), and we demonstrate that the index can be used as a financial market volatility indicator. We evaluate the NCI using financial documents from large Web news sources on a daily basis from October 2011 to July 2013 and analyse the interplay between financial markets and finance-related news. We hypothesise that strong cohesion in financial news reflects movements in the financial markets. Our results indicate that cohesiveness in financial news is highly correlated with and driven by volatility in financial markets.

Efficient Tracking of News Topics Based on Chronological Semantic Structures in a Large-Scale News Video Archive  

NASA Astrophysics Data System (ADS)

Recent advance in digital storage technology has enabled us to archive a large volume of video data. Thanks to this trend, we have archived more than 1,800 hours of video data from a daily Japanese news show in the last ten years. When considering the effective use of such a large news video archive, we assumed that analysis of its chronological and semantic structure becomes important. We also consider that providing the users with the development of news topics is more important to help their understanding of current affairs, rather than providing a list of relevant news stories as in most of the current news video retrieval systems. Therefore, in this paper, we propose a structuring method for a news video archive, together with an interface that visualizes the structure, so that users could track the development of news topics according to their interest, efficiently. The proposed news video structure, namely the “topic thread structure”, is obtained as a result of an analysis of the chronological and semantic relation between news stories. Meanwhile, the proposed interface, namely “mediaWalker II”, allows users to track the development of news topics along the topic thread structure, and at the same time watch the video footage corresponding to each news story. Analyses on the topic thread structures obtained by applying the proposed method to actual news video footages revealed interesting and comprehensible relations between news topics in the real world. At the same time, analyses on their size quantified the efficiency of tracking a user's topic-of-interest based on the proposed topic thread structure. We consider this as a first step towards facilitating video authoring by users based on existing contents in a large-scale news video archive.

Over-expression of proteins using a modified pBAD24 vector in E. coli expression system.  

PubMed

A modified pBAD24 vector (pBAD24M) was constructed with the araBAD promoter of the arabinose operon along with T7g10 sequence elements and a modified Shine-Dalgarno sequence. While both green fluorescent protein and granulocyte colony stimulating factor showed negligible expression under the original pBAD24 vector, they were expressed at >35% of total cellular protein with the modified vector. Similar results were obtained for staphylokinase wherein the pBAD24-SAK construct yielded 8 ng/10(6) c.f.u. of E. coli induced cells while the pBAD24M-SAK vector showed nearly 55 ng/10(6) c.f.u. induced bacterial cells as tested by ELISA. Interestingly, the expression levels using modified pBAD24 vector matched that achieved with T7 promoter based vector system. The modified pBAD24 vector therefore represents a simple and a useful prokaryotic expression system for efficient repression, modulation and elevated protein expression levels. PMID:19330488

Bad dream frequency in older adults with generalized anxiety disorder: prevalence, correlates, and effect of cognitive behavioral treatment for anxiety.  

PubMed

This study investigated the relation between generalized anxiety disorder (GAD) and frequency of bad dreams in older adults. A secondary analysis from a randomized clinical trial comparing cognitive behavioral therapy (CBT) for anxiety to enhanced usual care (EUC) assessed bad dream frequency at baseline, post treatment (3 months), and at 6, 9, 12, and 15 months. Of 227 participants (mean age = 67.4), 134 met GAD diagnostic criteria (CBT = 70, EUC = 64), with the remaining 93 serving as a comparison group. Patients with GAD had significantly more bad dreams than those without, and bad dream frequency was significantly associated with depression, anxiety, worry, and poor quality of life. CBT for anxiety significantly reduced bad dream frequency at post treatment and throughout follow up compared to EUC. PMID:23470116

Science versus News: On the Cutting Edge  

NASA Astrophysics Data System (ADS)

This session is to aid communication between scientists and journalists, to motivate astronomers to be active in communicating their science to the public via the press, and to help both astronomers and journalists to understand the constraints under which the other group is operating. The session consists of two talks of about 20 minutes, followed by a panel discussion. The first talk is "What Makes a Topic News?" This segment, by Miles O'Brien of CNN News, takes the AAS audiences behind the scenes in the world of producing science news stories. --- What drives selection of assignments? How does the science reporter convince their editor to cover a story? What factors about television producing help and also hurt getting science subjects across to the public? The second talk is "Public Knowledge on Science: The Growing Gap Between Scientists and the Taxpayer." This presentation by Jon Miller, a public opinion expert will emphasize the problems scientists and society, face in communicating to the public. --- What does the public know about science and scientific method? How much translation is required to communicate with the public to engage their interest without unacceptable compromise of scientific accuracy? The final segment is a panel of both science journalists and astronomers moderated by Steve Maran. Together they will tackle a question that gets to the heart of the Science-Vs-News controversies, "When Should Results Go Public?" Published too soon, science is called "hype"; Published too late, it is no longer "news." Should all results be peer reviewed first, and is that a satisfactory prerequisite? Do scientists take self-serving advantage of the public interest by making announcements before results appear in journals? How do we address the public desire to experience science unfolding and to see real-time data such as planetary science missions? The panelists are Dr. David Helfand, from Columbia University, Dr. Bruce Margon, from the University of Washington, Mr. Thomas Siegfried, from The Dallas Daily News, Ms. Kathy Sawyer, from The Washington Post, Mr. John Noble Wilford from The New York Times, and Ms. Ann Kellan from CNN.

Evaluation of the Pharmacokinetic Effects of Various Linking Group Using the 111In-DOTA-X-BBN(7-14)NH2 Structural Paradigm in a Prostate Cancer Model  

PubMed Central

The high incidence of BB2 receptor (BB2r) expression in various cancers has prompted investigators to pursue the development of BB2r-targeted agents for diagnostic imaging, chemotherapy and radiotherapy. Development of BB2r-targeted agents, based on the bombesin (BBN) peptide, has largely involved the use of the bifunctional chelate approach in which the linking group serves several key roles including pharmacokinetic modification. Understanding the in vivo properties of the various pharmacokinetic modifying linking groups is crucial for developing BB2r-targeted agents with improved targeting and clearance characteristics. The goal of this study was to systematically evaluate the pharmacokinetic profile of aliphatic hydrocarbon, aromatic and polyethylene glycol (ether) functional groups in order to obtain a better understanding of the in vivo properties of these pharmacokinetic modifiers. Specifically, we synthesized six radioconjugates with the structure 111In-DOTA-X-BBN(7-14)NH2, where X = 8-aminooctanoic acid (8-AOC), 5-amino-3-oxapentyl-succinamic acid (5-ADS), 8-amino-3,6-dioxaoctyl-succinamic acid (8-AOS), p-aminobenzoic acid (AMBA), Gly-AMBA and Gly-p-aminomethylbenzoic acid (Gly-AM2BA). All of the natIn-conjugates demonstrated nanomolar binding affinities to the BB2r. In CF-1 mice, the BB2r uptake in the pancreas of radioconjugates containing aromatic linking groups was found to be significantly higher at 1 hr post-injection than the radioconjugates with ether linker moieties. For PC-3 tumor bearing SCID mice, the tumor uptake was found to be 6.66 ± 2.00, 6.21 ± 1.57, 6.36 ± 1.60, 4.46 ± 0.81 and 7.76 ± 1.19 %ID/g for the 8-AOC, 8-ADS, AMBA, Gly-AMBA and Gly-AM2BA radioconjugates, respectively, at 15 min post-injection. By 24 hr post-injection, the radioconjugates containing aromatic groups exhibited the highest percentage tumor retention with 11.4, 19.8, 26.6, 25.8 and 25.5% relative to the 15 min values remaining in the tumor tissue for the 8-AOC, 8-ADS, AMBA, Gly-AMBA and Gly-AM2BA radioconjugates, respectively. Fused Micro-SPECT/CT imaging studies performed at 24 hr post-injection revealed substantial accumulation of radioactivity in the tumor tissue for all radioconjugates. In both biodistribution and Micro-SPECT/CT imaging studies, the radioconjugates containing aromatic linking groups typically exhibited significantly higher G.I. tract retention than the hydrocarbon or ether linking moieties. In conclusion, our studies indicate that radioconjugates incorporating aromatic linking groups, of the type investigated, generally demonstrated enhanced retention in BB2r expressing tissues in comparison to either the hydrocarbon or ether linking moieties. Furthermore, this investigation clearly demonstrates the significance of the linking group upon not only the in vivo clearance of the radiopharmaceutical, but on the in vivo uptake and retention of the BB2r-targeted agent in tumor tissue. Future designs of BB2r-targeted agents should include a careful consideration of the effect linking group functionality has upon tumor targeting and retention.

Autophagy inhibits chemotherapy-induced apoptosis through downregulating Bad and Bim in hepatocellular carcinoma cells  

PubMed Central

The tumor microenvironment, including ischemia, has been increasingly recognized as a critical factor in the process of tumor development. Hypoxia and nutrient deficiency resulting from ischemia widely exist in solid tumors. Recent studies have shown that hypoxia and nutrient deficiency contribute to chemoresistance by inducing autophagy, but the underlying mechanism remains unknown. This study aimed to explore the role of autophagy induced by low glucose and hypoxia (LH) in the chemoresistance of hepatocellular carcinoma cells. Our results demonstrated that LH induced autophagy and downregulated Bad and Bim in hepatocellular carcinoma cells. The inhibition of autophagy reversed the reduction of these pro-apoptotic factors during the LH treatment. Furthermore, Bad and Bim were also significantly downregulated by autophagy during the process that LH promoted the chemoresistance of hepatocellular carcinoma cells. In addition, RNAi or the overexpression of Bad and Bim can significantly reduce or increase chemotherapy-induced cell death, respectively. Taken together, these data indicate that the downregulation of Bad and Bim plays a significant role in the autophagy-induced chemoresistance of hepatocellular carcinoma cells.

An Effective News Recommendation Method for Microblog User  

PubMed Central

Recommending news stories to users, based on their preferences, has long been a favourite domain for recommender systems research. Traditional systems strive to satisfy their user by tracing users' reading history and choosing the proper candidate news articles to recommend. However, most of news websites hardly require any user to register before reading news. Besides, the latent relations between news and microblog, the popularity of particular news, and the news organization are not addressed or solved efficiently in previous approaches. In order to solve these issues, we propose an effective personalized news recommendation method based on microblog user profile building and sub class popularity prediction, in which we propose a news organization method using hybrid classification and clustering, implement a sub class popularity prediction method, and construct user profile according to our actual situation. We had designed several experiments compared to the state-of-the-art approaches on a real world dataset, and the experimental results demonstrate that our system significantly improves the accuracy and diversity in mass text data.

Tumor necrosis factor induces phosphorylation and translocation of BAD through a phosphatidylinositide-3-OH kinase-dependent pathway.  

PubMed

Tumor necrosis factor (TNF) induced the phosphorylation of BAD at serine 136 in HeLa cells under conditions that are not cytotoxic. BAD phosphorylation by TNF was dependent on phosphatidylinositide-3-OH kinase (PI3K) and was accompanied by the translocation of BAD from the mitochondria to the cytosol. Blocking the phosphorylation of BAD and its translocation to the cytosol with the PI3K inhibitor wortmannin activated caspase-3 and markedly potentiated the cytotoxicity of TNF. Transient transfection with a PI3K dominant negative mutant or a dominant negative mutant of the serine-threonine kinase Akt, the downstream target of PI3K and the enzyme that phosphorylates BAD, similarly potentiated the cytotoxicity of TNF. By contrast, transfection with a constitutively active Akt mutant protected against the cytotoxicity of TNF in the presence of wortmannin. Phosphorylation of BAD prevents its interaction with the antiapoptotic protein Bcl-XL. Transfection with a Bcl-XL expression vector protected against the cytotoxicity of TNF in the presence of wortmannin. The mechanism by which the inhibition of the phosphorylation of BAD is likely linked to the induction of lethal mitochondrial damage in TNF-intoxicated cells is discussed. PMID:10383455

Efficient generation of holographic news ticker in holographic 3DTV  

NASA Astrophysics Data System (ADS)

News ticker is used to show breaking news or news headlines in conventional 2-D broadcasting system. For the case of the breaking news, the fast creation is need, because the information should be sent quickly. In addition, if holographic 3- D broadcasting system is started in the future, news ticker will remain. On the other hands, some approaches for generation of CGH patterns have been suggested like the ray-tracing method and look-up table (LUT) method. However, these methods have some drawbacks that needs much time or needs huge memory size for look-up table. Recently, a novel LUT (N-LUT) method for fast generation of CGH patterns of 3-D objects with a dramatically reduced LUT without the loss of computational speed was proposed. Therefore, we proposed the method to efficiently generate the holographic news ticker in holographic 3DTV or 3-D movies using N-LUT method. The proposed method is largely consisted of five steps: construction of the LUT for each character, extraction of characters in news ticker, generation and shift of the CGH pattern for news ticker using the LUT for each character, composition of hologram pattern for 3-D video and hologram pattern for news ticker and reconstruct the holographic 3D video with news ticker. To confirm the proposed method, moving car in front of the castle is used as a 3D video and the words 'HOLOGRAM CAPTION GENERATOR' is used as a news ticker. From this simulation results confirmed the feasibility of the proposed method in fast generation of CGH patterns for holographic captions.

Good features of this practice include: pore water is a key exposure route for some organisms associated with sediments; pore water testing eliminates particle size effects; pore water analyses and tests can provide useful information regarding contamination and pollution. Bad features include: pore water is not the only exposure route; pore water tests lack chemical or biological realism: their "sensitivity" relative to other tests may be meaningless due to manipulation and laboratory artifacts; many sediment and surface dwelling organisms are not directly influenced by pore water. Bad features can become ugly if: other exposure pathways are not considered (for toxicity or bioaccumulation); manipulation techniques are not appropriate; pore water tests are inappropriately linked to population-level effects. Pore water testing and analyses can be effective tools provided their limitations are well understood by researchers and managers. PMID:12146818
