Humiliation lacks an empirically derived definition, sometimes simply being equated with shame. We approached the conceptualisation of humiliation from a prototype perspective, identifying 61 features of humiliation, some of which are more central to humiliation (e.g. losing self-esteem) than others (e.g. shyness). Prototypical humiliation involved feeling powerless, small, and inferior in a situation in which one was brought down and in which an audience was present, leading the person to appraise the situation as unfair and resulting in a mix of emotions, most notably disappointment, anger, and shame. Some of the features overlapped with those of shame (e.g. looking like a fool, losing self-esteem, presence of an audience) whereas other features overlapped with those of anger (e.g. being brought down, unfairness). Which specific features are present may determine whether the humiliation experience becomes more shame- or anger-like (or a combination thereof).

Affective dimensions of intergroup humiliation.
Directory of Open Access Journals (Sweden)
Bernhard Leidner
Full Text Available Despite the wealth of theoretical claims about the emotion of humiliation and its effect on human relations, there has been a lack of empirical research investigating what it means to experience humiliation. We studied the affective characteristics of humiliation, comparing the emotional experience of intergroup humiliation to two other emotions humiliation is often confused with: anger and shame. The defining characteristics of humiliation were low levels of guilt and high levels of other-directed outrage (like anger and unlike shame, and high levels of powerlessness (like shame and unlike anger. Reasons for the similarities and differences of humiliation with anger and shame are discussed in terms of perceptions of undeserved treatment and injustice. Implications for understanding the behavioral consequences of humiliation and future work investigating the role of humiliation in social life are discussed.

Toward a psychology of humiliation in asymmetric conflict.
McCauley, Clark
2017-04-01
Humiliation is often cited in attempts to understand the origins of asymmetric conflicts, especially conflicts involving terrorism. This article reviews common usage, expert opinion, and experiences in interpersonal and intergroup conflicts to suggest a construct definition of humiliation as a combination of anger and shame. Following appraisal theory, this definition distinguishes between the situational appraisals associated with humiliation (insult and injury; failure to retaliate) and the emotional experience of humiliation (in which the combination of anger and shame may be more synergism than summation). Research on humiliation has barely begun and focuses on interpersonal relations; a crucial issue is whether interpersonal humiliation is the same experience as the intergroup humiliation salient in accounts of terrorism and terrorists. Also important is the prediction that the targets of terrorist attack will experience humiliation if the terrorists are unknown or unreachable; thus failure to retaliate may humiliate the strong as well as the weak in asymmetric conflict. Better understanding of humiliation may be useful for understanding both terrorist violence and government reactions to this violence. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Human dignity, humiliation, and torture.
Luban, David
2009-09-01
Modern human rights instruments ground human rights in the concept of human dignity, without providing an underlying theory of human dignity. This paper examines the central importance of human dignity, understood as not humiliating people, in traditional Jewish ethics. It employs this conception of human dignity to examine and criticize U.S. use of humiliation tactics and torture in the interrogation of terrorism suspects.

Outpatient clinics in Korea usually have local DUR (drug utilisation review) systems, which are integrated with EMRs or health insurance claims submission systems. Whenever, the government announces a list of drug contraindications, each local DUR system loads the list and applies it in practice. In December 2010, a nationwide DUR system was introduced. This study is to investigate the impact of the nationwide DUR system on prescribing practices where local DUR systems are already operating. Between January 2009 and December 2012 the monthly number of drugs per prescription was retrieved from the health insurance claims data warehouse at the Health Insurance Review and Assessment (HIRA). The monthly proportions of 3 DDI (drug-drug interaction) pairs, 6 drug-age contraindications, and 3 drug-pregnancy contraindications from January 2007 to December 2012, at the outpatient clinic level, were also retrieved. An interrupted time series analysis was used for controlling government announcements of drug contraindications. There was no difference in the number of drugs per prescription before and after the introduction of the nationwide DUR system. Most proportions of the 3 DDI pairs, 6 drug-age contraindications, and 3 drug-pregnancy contraindications, were significantly reduced following the government announcement of drug contraindications in the short term and/or long term. The number of drugs per prescription was not related to the nationwide DUR introduction in places where local DUR systems are operating. The introduction of duplicate guidelines, in locations where the guidelines were already well followed, is considered to be the main reason for this. Furthermore, the Doctor's ignorance of alerts, and their continued substitution of regulated drugs, for non-regulated drugs, likely played a role in nullifying the effectiveness of the nationwide DUR system.

To demonstrate that the intraocular pressure (IOP)-lowering effect of travoprost 0.004% preserved with polyquaternium-1 (travoprost benzalkonium chloride [BAK]-free) is non-inferior to that of travoprost 0.004% preserved with benzalkonium chloride (travoprost BAK) in patients with ocular hypertension or open-angle glaucoma. A total of 371 patients randomly received travoprost BAK-free (n=185) or travoprost BAK (n=186) dosed once daily in the evening for 3 months. Patients were evaluated at 9 am, 11 AM, and 4 PM at baseline, weeks 2 and 6, and month 3. Intraocular pressure was also evaluated 36 and 60 hours after the month 3 visit. Travoprost BAK-free is non-inferior to travoprost BAK. The 95% upper confidence limits for the difference in mean IOP at month 3 (primary efficacy) were 0.5 mmHg, 0.6 mmHg, and 0.5 mmHg, at 9 AM, 11 AM, and 4 PM, respectively. Mean IOP reductions from baseline ranged from 7.6 to 8.7 mmHg in the travoprost BAK-free group and from 7.7 to 9.2 mmHg in the travoprost BAK group. At 36 and 60 hours after the last dose, mean IOP remained 6.8 mmHg and 5.7 mmHg below baseline in the travoprost BAK-free group, vs 7.3 mmHg and 6.0 mmHg in the travoprost BAK group, respectively. The safety profile of travoprost BAK-free was similar to that of travoprost BAK. Travoprost BAK-free safely and effectively lowers IOP in eyes with open-angle glaucoma or ocular hypertension. This BAK-free formulation has comparable safety, efficacy, and duration of IOP-lowering effect to travoprost preserved with BAK. Travoprost BAK-free is an effective option for IOP reduction while avoiding BAK exposure.

Avoiding humiliations in the clinical encounter.
Malterud, Kirsti; Hollnagel, Hanne
2007-06-01
To explore potentials for avoiding humiliations in clinical encounters, especially those that are unintended and unrecognized by the doctor. Furthermore, to examine theoretical foundations of degrading behaviour and identify some concepts that can be used to understand such behaviour in the cultural context of medicine. Finally, these concepts are used to build a model for the clinician in order to prevent humiliation of the patient. Empirical studies document experiences of humiliation among patients when they see their doctor. Philosophical and sociological analysis can be used to explain the dynamics of unintended degrading behaviour between human beings. Skjervheim, Vetlesen, and Bauman have identified the role of objectivism, distantiation, and indifference in the dynamics of evil acts, pointing to the rules of the cultural system, rather than accusing the individual of bad behaviour. Examining the professional role of the doctor, parallel traits embedded in the medical culture are demonstrated. According to Vetlesen, emotional awareness is necessary for moral perception, which again is necessary for moral performance. A better balance between emotions and rationality is needed to avoid humiliations in the clinical encounter. The Awareness Model is presented as a strategy for clinical practice and education, emphasizing the role of the doctor's own emotions. Potentials and pitfalls are discussed.

To compare the toxicological profile of a new formulation of travoprost 0.004% ophthalmic solution (travoprost PQ), containing the preservative polyquaternium-1(PQ, polyquad), with the commercially available formulation of benzalkonium chloride (BAK)-preserved travoprost 0.004% ophthalmic solution (travoprost BAK) and BAK-preserved latanoprost 0.005% ophthalmic solution (latanoprost BAK). Human conjunctival epithelial cells were incubated with phosphate-buffered saline (PBS), BAK 0.015%, BAK 0.020%, PQ 0.001%, travoprost PQ preserved with PQ 0.001%, travoprost preserved with BAK 0.015%, or latanoprost preserved with BAK 0.020%. Six toxicological assays were used to assess: cell viability (neutral red, Alamar blue), apoptosis (YO-PRO-1, Hoechst 33342), and oxidative stress (H(2)DCF-DA, hydroethidine). Apoptosis and oxidative stress were each reported according to cell viability as observed with neutral red and Alamar blue for a total of 10 analyses per treatment depending on the cell viability test used to interpret apoptosis and oxidative stress responses. There were no significant differences in toxicity between cells exposed to PBS and cells exposed to travoprost PQ (10/10 analyses) or PQ 0.001% (9/10 analyses). Ten out of 10 analyses revealed that travoprost PQ produced significantly less cytotoxicity than latanoprost BAK (p solution in 9 of 10 analyses (p < 0.0001). A panel of in vitro toxicity analyses supports the safety of travoprost PQ. Travoprost PQ may be better for ocular surface health than BAK-preserved formulations of latanoprost or travoprost but clinical studies are required to validate these comparisons.

To compare the duration of action of travoprost ophthalmic solution 0.004% (Travatan Z) formulated without benzalkonium chloride (BAK) to travoprost ophthalmic solution 0.004% formulated with BAK (Travatan). This was a prospective, randomized, double-masked study. Patients with open-angle glaucoma or ocular hypertension were randomized to receive 2 weeks of once-daily therapy with travoprost BAK-free or travoprost with BAK. Patients received the last dose of medication on day 13 and then intraocular pressure (IOP) was assessed every 12 hours for 60 hours. Statistical analysis included change in IOP from baseline for each group and comparison of mean IOP between groups. Of the 109 patients enrolled, 106 patients completed the study. Untreated mean baseline IOP at 8 AM was 26.9 mm Hg in the travoprost BAK-free group and 27.1 mm Hg in the travoprost with BAK group. At 12, 24, 36, 48, and 60 hours after the last dose, mean IOP in the travoprost BAK-free group was 18.7, 17.2, 19.5, 18.7, and 20.8 mm Hg, respectively; whereas mean IOP in the travoprost with BAK group was 18.5, 16.8, 19.7, 18.0, and 20.8 mm Hg, respectively. Mean IOP at all time points after the last dose of medication was >6 mm Hg lower than the 8 AM baseline in both groups. Between-group differences were within +/-0.6 mm Hg at all postdose time points. There were no statistically significant differences between the 2 treatment groups at baseline or at any postdose time point. Drug-related side effects were uncommon, mild in intensity, and comparable between groups. Travoprost without BAK has similar IOP-lowering efficacy and safety compared with travoprost preserved with BAK. Both formulations of travoprost have a prolonged duration of action, with statistically and clinically significant reductions from baseline persisting up to 60 hours after the last dose.

Seeing and being seen: narcissistic pride and narcissistic humiliation.
Steiner, John
2006-08-01
Seeing and being seen are important aspects of narcissism, where self-consciousness is always a feature, and one which becomes acute when a patient loses the protection of a narcissistic relationship and is obliged to tolerate a degree of separateness. Having felt hidden and protected, he now feels conspicuous and exposed to a gaze which makes him vulnerable to humiliation. This often has a devastating and unbearable quality to it, particularly when it is felt to arise in retaliation to the patient's own use of gaze to establish a superiority which allowed the patient to look down on others. The need to avoid or cut short such humiliation may be so acute that the patient cannot deal with guilt and other emotions connected with loss which might otherwise be bearable. The author argues that development is impeded unless the patient is able to gain support to make the humiliation better understood and hence better tolerated. He describes some sessions from an analysis to illustrate how, in some analytic situations, much of the patient's concern and many of his defensive manoeuvres aim to reduce or to reverse experiences of humiliation. An understanding of the mechanisms involved seemed to enable some development to proceed.

Full Text Available The backs of dump trucks have transformed to not only as a transportation mechanism, but also as visual communication media. This phenomena goes along with the many advertisements that utilizes this kind of medium in promoting certain products. But the backs of dump trucks become a promotional medium because of the already many paintings painted on them, which they are originally plain on the right, left, and the back sides. Women become figures that many portray as their painted subjects. This article focuses more on the painting phenomena that uses the female figures through a gender study, to see whether woman representations in the paintings of the backs of trucks are signified as having imbalanced gender relations. Abstract in Bahasa Indonesia: Bak truk telah menjelma tidak saja menjadi alat transportasi namun juga media komunikasi visual seiring dengan semakin banyaknya iklan yang memanfaatkan media ini dalam mempromosikan suatu produk. Namun perjalanan bak truk menjadi media promosi diawali oleh bertebarannya lukisan yang memanfaatkan bak truk yang semula kosong di sisi kanan, kiri maupun belakang truk. Perempuan menjadi figur yang banyak dipakai sebagai objek lukis. Tulisan ini lebih menyoroti fenomena lukisan yang banyak mengambil figur perempuan dalam kajian gender, untuk melihat apakah representasi perempuan dalam lukisan di bak truk tersebut dimaknai sebagai adanya ketimpangan dalam relasi gender. Kata kunci: representasi, perempuan, bak truk, lukisan, relasi gender.

The novel Candida albicans transporter Dur31 Is a multi-stage pathogenicity factor.
Directory of Open Access Journals (Sweden)
François L Mayer
Full Text Available Candida albicans is the most frequent cause of oral fungal infections. However, the exact pathogenicity mechanisms that this fungus employs are largely unknown and many of the genes expressed during oral infection are uncharacterized. In this study we sought to functionally characterize 12 previously unknown function genes associated with oral candidiasis. We generated homozygous knockout mutants for all 12 genes and analyzed their interaction with human oral epithelium in vitro. Eleven mutants caused significantly less epithelial damage and, of these, deletion of orf19.6656 (DUR31 elicited the strongest reduction in pathogenicity. Interestingly, DUR31 was not only involved in oral epithelial damage, but in multiple stages of candidiasis, including surviving attack by human neutrophils, endothelial damage and virulence in vivo. In silico analysis indicated that DUR31 encodes a sodium/substrate symporter with 13 transmembrane domains and no human homologue. We provide evidence that Dur31 transports histatin 5. This is one of the very first examples of microbial driven import of this highly cytotoxic antimicrobial peptide. Also, in contrast to wild type C. albicans, dur31Δ/Δ was unable to actively increase local environmental pH, suggesting that Dur31 lies in the extracellular alkalinization hyphal auto-induction pathway; and, indeed, DUR31 was required for morphogenesis. In agreement with this observation, dur31Δ/Δ was unable to assimilate the polyamine spermidine.

When Is Humiliation More Intense? The Role of Audience Laughter and Threats to the Self
Directory of Open Access Journals (Sweden)
Agneta H. Fischer
2017-04-01
Full Text Available In personal accounts, humiliation is often reported as a very intense, painful, negative emotion. We report two scenario studies in which we explored two factors that may contribute to the intense character of humiliation: (1 unwanted, negative public exposure, and (2 a threat to central aspects of one's identity. Study 1 (N = 115 assessed emotional reactions to a public insult when an audience responded with either laughter or not and when someone from the audience offered support after the insult or no support was offered. Results showed that the intensity of humiliation increased when people laughed after the insult. However, support offered after the insult had no effect on reported humiliation. Study 2 (N = 99 focused on threats to different self-related values and showed stronger reports of humiliation when central self-related values were threatened than when less central self-related values were threatened. Study 2 also replicated the audience-effect from Study 1, but only when central self-related values were threatened and not when less central self-related values were threatened. Limitations of these studies (e.g., the use of scenarios and potential avenues for future research, such as the (long-term consequences of humiliation and humiliation in the context of social media, are discussed.

Enhanced tocopherol levels during early germination events in Chamaerops humilis var. humilis seeds.
Siles, Laura; Alegre, Leonor; Tijero, Verónica; Munné-Bosch, Sergi
2015-10-01
Most angiosperms accumulate vitamin E in the form of tocopherols in seeds, exerting a protective antioxidant role. However, several palm trees principally accumulate tocotrienols, rather than tocopherols, in seeds, as it occurs in other monocots. To unravel the protective role of either tocopherols or tocotrienols against lipid peroxidation during seed germination in Chamaerops humilis var. humilis; seed viability, natural and induced germination capacity, seed water content, malondialdehyde levels (as an indicator of the extent of lipid peroxidation) and vitamin E levels (including both tocopherols and tocotrienols) were examined at various germination phases in a simulated, natural seed bank. At the very early stages of germination (operculum removal), malondialdehyde levels increased 2.8-fold, to decrease later up to 74%, thus indicating a transient lipid peroxidation at early stages of germination. Tocopherol levels were absent in quiescent seeds and did not increase during operculum removal, but increased later presumably dampening malondialdehyde accumulation. Thereafter, tocopherols continued increasing, while lipid peroxidation levels decreased. By contrast, tocotrienols levels remained constant or even decreased as germination progressed, showing no correlation with lipid peroxidation levels. We hypothesize that despite their high tocotrienol content, seeds synthesize tocopherols during germination to protect lipids from peroxidation events. Copyright © 2015 Elsevier Ltd.

Disappearing population of Betula humilis Schrk. on the Maliszewskie Lake, NE Poland
Directory of Open Access Journals (Sweden)
Chrzanowska Agnieszka
2015-03-01
Full Text Available Betula humilis Schrk. is an endangered glacial relict inhabiting wet meadows, natural and drained fens. One of its declining populations is located on the Maliszewskie Lake (the Wizna swamp, north-eastern Poland. The goal of the present study was to estimate the number of B. humilis individuals in this locality. In the Maliszewskie Lake population, 59 ramets, grouped into three clusters, were found. Twelve nuclear microsatellite loci were chosen to genotype 52 ramets. The analysis revealed that all the shoots within the single cluster had the same genotypes at the loci considered. This means that each cluster constituted one genetically distinct individual; thus, there were only three individuals of B. humilis in the studied population. The maintenance of the B. humilis population in the Maliszewskie Lake area requires urgent active protection involving removal of the shading vegetation. In fact, the entire Maliszewskie Lake is worthy of protection because of its hitherto unexplained origin and the occurrence of many endangered bird species.

"Teaching by humiliation" and mistreatment of medical students in clinical rotations: a pilot study.
Scott, Karen M; Caldwell, Patrina Hy; Barnes, Elizabeth H; Barrett, Jenny
2015-08-17
To generate a contemporary understanding of "teaching by humiliation" as experienced by medical students in Australia. In this pilot study, we surveyed final-stage medical students from two Australian medical schools about their experiences of teaching by humiliation during their adult and paediatric clinical rotations. The students were invited to complete the anonymous survey at the end of their paediatric rotation in Semester 2 of 2013. We used descriptive statistics to analyse quantitative data, and a grounded theory approach to analyse qualitative data. Student reports of experiencing or witnessing teaching by humiliation during their adult and paediatric clinical rotations. Of 151 students invited to participate, 146 (96.7%) completed the survey. Most students reported experiencing (108; 74.0%) or witnessing (118; 83.1%) teaching by humiliation during adult clinical rotations. Smaller but still sizeable proportions had experienced (42; 28.8%) or witnessed (64; 45.1%) it during their paediatric clinical rotation. The humiliating and intimidating behaviours students experienced were mostly more subtle than overt and included aggressive and abusive questioning techniques. The students' responses to these practices ranged from disgust and regret about entering the medical profession to endorsement of teachers' public exposure of a student's poor knowledge. Practices associated with humiliating medical students persist in contemporary medical education. These practices need to be eradicated, given the evidence that they affect students' learning and mental health and are dissonant with formal professionalism curricula. Interventions are needed to interrupt the transgenerational legacy and culture in which teaching by humiliation is perpetuated.

BAK overexpression mediates p53-independent apoptosis inducing effects on human gastric cancer cells
Directory of Open Access Journals (Sweden)
Liu Jun
2004-07-01
Full Text Available Abstract Background BAK (Bcl-2 homologous antagonist/killer is a novel pro-apoptotic gene of the Bcl-2 family. It has been reported that gastric tumors have reduced BAK levels when compared with the normal mucosa. Moreover, mutations of the BAK gene have been identified in human gastrointestinal cancers, suggesting that a perturbation of BAK-mediated apoptosis may contribute to the pathogenesis of gastric cancer. In this study, we explored the therapeutic effects of gene transfer mediated elevations in BAK expression on human gastric cancer cells in vitro. Methods Eukaryotic expression vector for the BAK gene was constructed and transferred into gastric cancer cell lines, MKN-45 (wild-type p53 and MKN-28 (mutant-type p53. RT-PCR and Western Blotting detected cellular BAK gene expression. Cell growth activities were detected by MTT colorimetry and flow cytometry, while apoptosis was assayed by electronic microscopy and TUNEL. Western Blotting and colorimetry investigated cellular caspase-3 activities. Results BAK gene transfer could result in significant BAK overexpression, decreased in vitro growth, cell cycle G0/G1 arrest, and induced apoptosis in gastric cancer cells. In transferred cells, inactive caspase-3 precursor was cleaved into the active subunits p20 and p17, during BAK overexpression-induced apoptosis. In addition, this process occurred equally well in p53 wild-type (MKN-45, or in p53 mutant-type (MKN-28 gastric cancer cells. Conclusions The data presented suggests that overexpression of the BAK gene can lead to apoptosis of gastric cancer cells in vitro, which does not appear to be dependent on p53 status. The action mechanism of BAK mediated apoptosis correlates with activation of caspase-3. This could be served as a potential strategy for further development of gastric cancer therapies.

A ground penetrating radar (GPR) survey was done across the Bok Bak Fault zone in Baling, Kedah in order to investigate the shallow subsurface geology of the Bok Bak fault zone, its extension and associated weak zones within the study area. GPR data acquisition was compared with visual inspection on the slope of the outcrop. Ten GPR profiles were acquired using 250 MHz GPR frequency. Basic data processing and filtering to reduce some noise and unwanted signal was done using MALA RAMAC Ground Vision software. The data penetrate around 2 meters in depth for all survey lines. In most lines shows clear images of shallowest Bok Bak Fault (NW trending) as detected at distance of 28 m horizontal marker. It also exhibits several sets of faults as a result of Bok Bak Fault deformation, including the conjugate NE trending fault (Lubok Merbau Fault). Active seismicity encompasses the Malay-Thai Peninsular trigger the changes of Bok Bak Fault dipping direction, steeper dips of conjugate faults and faults or fractures rotational movement. (author)

The Problem of Humiliation in Peer Review
Comer, Debra R.; Schwartz, Michael
2014-01-01
This paper examines the problem of vituperative feedback from peer reviewers. We argue that such feedback is morally unacceptable, insofar as it humiliates authors and damages their dignity. We draw from social-psychological research to explore those aspects of the peer-review process in general and the anonymity of blind reviewing in particular…

Drought (Water deficit, WD) poses a serious threat to extensively economic losses of trees throughout the world. Chinese dwarf cherry ( Cerasus humilis ) is a good perennial plant for studying the physiological and sophisticated molecular network under WD. The aim of this study is to identify the effect of WD on C. humilis through physiological and global proteomics analysis and improve understanding of the WD resistance of plants. Currently, physiological parameters were applied to investigate C. humilis response to WD. Moreover, we used two-dimensional gel electrophoresis (2DE) to identify differentially expressed proteins in C. humilis leaves subjected to WD (24 d). Furthermore, we also examined the correlation between protein and transcript levels. Several physiological parameters, including relative water content and Pn were reduced by WD. In addition, the malondialdehyde (MDA), relative electrolyte leakage (REL), total soluble sugar, and proline were increased in WD-treated C. humilis . Comparative proteomic analysis revealed 46 protein spots (representing 43 unique proteins) differentially expressed in C. humilis leaves under WD. These proteins were mainly involved in photosynthesis, ROS scavenging, carbohydrate metabolism, transcription, protein synthesis, protein processing, and nitrogen and amino acid metabolisms, respectively. WD promoted the CO 2 assimilation by increase light reaction and Calvin cycle, leading to the reprogramming of carbon metabolism. Moreover, the accumulation of osmolytes (i.e., proline and total soluble sugar) and enhancement of ascorbate-glutathione cycle and glutathione peroxidase/glutathione s-transferase pathway in leaves could minimize oxidative damage of membrane and other molecules under WD. Importantly, the regulation role of carbohydrate metabolisms (e. g. glycolysis, pentose phosphate pathways, and TCA) was enhanced. These findings provide key candidate proteins for genetic improvement of perennial plants metabolism under

BAK is a key effector of mitochondrial outer membrane permeabilization (MOMP) whose molecular mechanism of action remains to be fully dissected in intact cells, mainly due to the inherent complexity of the intracellular apoptotic machinery. Here we show that the core features of the BAK-driven MOMP pathway can be reproduced in a highly simplified in vitro system consisting of recombinant human BAK lacking the carboxyl-terminal 21 residues (BAKΔC) and tBID in combination with liposomes bearing an appropriate lipid environment. Using this minimalist reconstituted system we established that tBID suffices to trigger BAKΔC membrane insertion, oligomerization, and pore formation. Furthermore, we demonstrate that tBID-activated BAKΔC permeabilizes the membrane by forming structurally dynamic pores rather than a large proteinaceous channel of fixed size. We also identified two distinct roles played by mitochondrial lipids along the molecular pathway of BAKΔC-induced membrane permeabilization. First, using several independent approaches, we showed that cardiolipin directly interacts with BAKΔC, leading to a localized structural rearrangement in the protein that "primes" BAKΔC for interaction with tBID. Second, we provide evidence that selected curvature-inducing lipids present in mitochondrial membranes specifically modulate the energetic expenditure required to create the BAKΔC pore. Collectively, our results support the notion that BAK functions as a direct effector of MOMP akin to BAX and also adds significantly to the growing evidence indicating that mitochondrial membrane lipids are actively implicated in BCL-2 protein family function.

This study assessed the association between exposure to political violence over a 25-year period and adult functioning among a population that has experienced protracted and severe political conflict. Instead of aggregating exposure to political violence across time and type of exposure, as is commonly done, the event history calendar pioneered in this study assessed exposure to five forms of political violence annually from 1987 to 2011 in a representative sample of 1788 adults, aged 37 on average, in the occupied Palestinian territories (West Bank, East Jerusalem, and the Gaza Strip). This method allowed for the identification of trajectories of exposure to political violence from childhood to adulthood using latent profile analysis. We then correlated the trajectories of exposure to measures of economic, political, community, family, psychological, and health functioning. As expected, being shot at, having one's home raided, being hit or kicked, being verbally abused, and witnessing someone close being humiliated were all elevated during periods of heightened political conflict (the first intifada (1987-1993) and, less so, the second intifada (2000-2005)). In addition, 12% of women and men reported high and persistent levels of exposure to humiliation (being verbally abused and/or witnessing someone close being humiliated) across the entire 25-year period. These individuals lived predominantly in neighborhoods with a high Israeli military presence. Compared to those who experienced periodic exposure to political violence, persistently humiliated men and women reported significantly lower health, economic, political, and psychological functioning, as well as higher social cohesion and political expression. Relevant literatures are reviewed when concluding that persistent humiliation is a neglected form of political violence that is best represented as a direct (versus structural), acute (versus chronic), macro (versus micro), and high-grade (versus low

A BAX/BAK and cyclophilin D-independent intrinsic apoptosis pathway.
Directory of Open Access Journals (Sweden)
Sebastián Zamorano
Full Text Available Most intrinsic death signals converge into the activation of pro-apoptotic BCL-2 family members BAX and BAK at the mitochondria, resulting in the release of cytochrome c and apoptosome activation. Chronic endoplasmic reticulum (ER stress leads to apoptosis through the upregulation of a subset of pro-apoptotic BH3-only proteins, activating BAX and BAK at the mitochondria. Here we provide evidence indicating that the full resistance of BAX and BAK double deficient (DKO cells to ER stress is reverted by stimulation in combination with mild serum withdrawal. Cell death under these conditions was characterized by the appearance of classical apoptosis markers, caspase-9 activation, release of cytochrome c, and was inhibited by knocking down caspase-9, but insensitive to BCL-X(L overexpression. Similarly, the resistance of BIM and PUMA double deficient cells to ER stress was reverted by mild serum withdrawal. Surprisingly, BAX/BAK-independent cell death did not require Cyclophilin D (CypD expression, an important regulator of the mitochondrial permeability transition pore. Our results suggest the existence of an alternative intrinsic apoptosis pathway emerging from a cross talk between the ER and the mitochondria.

Full Text Available Braya humilis is a member of the Euclidieae tribe within the family Brassicaceae. This species exhibits a broad range of adaptations to different climatic zones and latitudes as it has a distribution that ranges from northern Asia to the arctic-alpine regions of northern North America. In China, B. humilis is mainly found on the Qinghai-Tibetan Plateau (QTP and in adjacent arid regions. In this study, we sequenced a sample from an arid region adjacent to the QTP using the Illumina platform generating a total of 46,485 highly accurate unigenes, of which 78.41% were annotated by BLASTing versus public protein databases. The B. humilis transcriptome is characterized by a high level of sequence conservation compared with its close relative, Arabidopsis thaliana. We also used reciprocal blast to identify shared orthologous genes between B. humilis and four other sequenced Brassicaceae species (i.e. A. thaliana, A. lyrata, Capsella rubella, and Thellungiella parvula. To enable precise characterization of orthologous genes, the early-diverging basal angiosperm Amborella trichopoda was also included. A total of 6,689 orthologous genes were identified before stricter criteria for the determination of e-values, amino acid hit lengths, and identity values was applied to further reduce this list. This led to a final list of 381 core orthologous genes for B. humilis; 39 out of these genes are involved in salt and osmotic stress responses and estimations of nonsynonymous/synonymous substitution ratios for this species and A. thaliana orthologs show that these genes are under purifying selection in B. humilis. Expression of six genes was detected in B. humilis seedlings under salt and osmotic stress treatments. Comparable expression patterns to their counterparts in Arabidopsis suggest that these orthologous genes are both sequence and functional conservation. The results of this study demonstrate that the environmental adaptations of B. humilis are mainly the

So far there exists no corresponding quality test procedures and grading standards for the seed of Prunus humilis, which is one of the important source of base of semen pruni. Therefor we set up test procedures that are adapt to characteristics of the P. humilis seed through the study of the test of sampling, seed purity, thousand-grain weight, seed moisture, seed viability and germination percentage. 50 cases of seed specimens of P. humilis tested. The related data were analyzed by cluster analysis. Through this research, the seed quality test procedure was developed, and the seed quality grading standard was formulated. The seed quality of each grade should meet the following requirements: for first grade seeds, germination percentage ≥ 68%, thousand-grain weight 383 g, purity ≥ 93%, seed moisture ≤ 5%; for second grade seeds, germination percentage ≥ 26%, thousand-grain weight ≥ 266 g, purity ≥ 73%, seed moisture ≤9%; for third grade seeds, germination percentage ≥ 10%, purity ≥ 50%, thousand-grain weight ≥ 08 g, seed moisture ≤ 13%.

In plants, urea derives either from root uptake or protein degradation. Although large quantities of urea are released during senescence, urea is mainly seen as a short-lived nitrogen (N) catabolite serving urease-mediated hydrolysis to ammonium. Here, we investigated the roles of DUR3 and of urea in N remobilization. During natural leaf senescence urea concentrations and DUR3 transcript levels showed a parallel increase with senescence markers like ORE1 in a plant age- and leaf age-dependent manner. Deletion of DUR3 decreased urea accumulation in leaves, whereas the fraction of urea lost to the leaf apoplast was enhanced. Under natural and N deficiency-induced senescence DUR3 promoter activity was highest in the vasculature, but was also found in surrounding bundle sheath and mesophyll cells. An analysis of petiole exudates from wild-type leaves revealed that N from urea accounted for >13% of amino acid N. Urea export from senescent leaves further increased in ureG-2 deletion mutants lacking urease activity. In the dur3 ureG double insertion line the absence of DUR3 reduced urea export from leaf petioles. These results indicate that urea can serve as an early metabolic marker for leaf senescence, and that DUR3-mediated urea retrieval contributes to the retranslocation of N from urea during leaf senescence.

Plasma membrane-localized pattern recognition receptors (PRRs) such as FLAGELLIN SENSING2 (FLS2), EF-TU RECEPTOR (EFR), and CHITIN ELICITOR RECEPTOR KINASE1 (CERK1) recognize microbe-associated molecular patterns (MAMPs) to activate pattern-triggered immunity (PTI). A reverse genetics approach on genes responsive to the priming agent β-aminobutyric acid (BABA) revealed IMPAIRED OOMYCETE SUSCEPTIBILITY1 (IOS1) as a critical PTI player. Arabidopsis thaliana ios1 mutants were hypersusceptible to Pseudomonas syringae bacteria. Accordingly, ios1 mutants showed defective PTI responses, notably delayed upregulation of the PTI marker gene FLG22-INDUCED RECEPTOR-LIKE KINASE1, reduced callose deposition, and mitogen-activated protein kinase activation upon MAMP treatment. Moreover, Arabidopsis lines overexpressing IOS1 were more resistant to bacteria and showed a primed PTI response. In vitro pull-down, bimolecular fluorescence complementation, coimmunoprecipitation, and mass spectrometry analyses supported the existence of complexes between the membrane-localized IOS1 and BRASSINOSTEROID INSENSITIVE1-ASSOCIATED KINASE1 (BAK1)-dependent PRRs FLS2 and EFR, as well as with the BAK1-independent PRR CERK1. IOS1 also associated with BAK1 in a ligand-independent manner and positively regulated FLS2-BAK1 complex formation upon MAMP treatment. In addition, IOS1 was critical for chitin-mediated PTI. Finally, ios1 mutants were defective in BABA-induced resistance and priming. This work reveals IOS1 as a novel regulatory protein of FLS2-, EFR-, and CERK1-mediated signaling pathways that primes PTI activation. PMID:27317676

BIM-Mediated Membrane Insertion of the BAK Pore Domain Is an Essential Requirement for Apoptosis
Directory of Open Access Journals (Sweden)
Kathrin Weber
2013-10-01
Full Text Available BAK activation represents a key step during apoptosis, but how it converts into a mitochondria-permeabilizing pore remains unclear. By further delineating the structural rearrangements involved, we reveal that BAK activation progresses through a series of independent steps: BH3-domain exposure, N-terminal change, oligomerization, and membrane insertion. Employing a “BCL-XL-addiction” model, we show that neutralization of BCL-XL by the BH3 mimetic ABT-737 resulted in death only when cells were reconstituted with BCL-XL:BAK, but not BCL-2/ BCL-XL:BIM complexes. Although this resembles the indirect model, release of BAK from BCL-XL did not result in spontaneous adoption of the pore conformation. Commitment to apoptosis required association of the direct activator BIM with oligomeric BAK promoting its conversion to a membrane-inserted pore. The sequential nature of this cascade provides multiple opportunities for other BCL-2 proteins to interfere with or promote BAK activation and unites aspects of the indirect and direct activation models.

Experimental effect of temperature and sedimentation on bleaching of the two Red Sea corals Stylophora pistillata and Acropora humilis. Nusantara Bioscience 5: 73-83. At 26°C (the control sample, the loss of zooxanthellae by each of the two studied corals Stylophora pistillata and Acropora humilis was very low. Cell viability of the two studied corals was similar at 26 and 29°C, but depicted a sharp decline of zooxanthellae lost at 31°C through time. As the temperature increased to 35°C, the loss of zooxanthellae from each host increased both with time and temperature elevation. The coral A. humilis had a higher decrease in its zooxanthellae densities than S. pistillata at the same treatment. Bleaching temperature threshold was 33°C or less for the two species S. pistillata and A. humilis where 51% of their zooxanthellae were lost after 24 h of exposure. In samples exposed to sediment concentration of 0.1 mg/cm2/L, zooxanthellae densities of A. humilis and S. pistillata did not show any decrease after 1 day. However, after 1 days of exposure to 0.5 mg/cm2/L, zooxanthellae densities were significantly different from those of the controls. Increases in sediment concentration to 1 mg/cm2/L caused a decrease in zooxanthellae densities that vary greatly over time. Measurements of zooxanthellae densities of A. humilis and S. pistillata at this stage revealed a highly significant difference between exposed and control sample. At 1 g/cm2/L, the number of zooxanthellae lost from A. humilis was higher than those lost from S. pistillata at same time. It is suggested that, the normal sedimentation rate for A. humilis and S. pistillata to be in an order of 1 mg/cm2/L or less.

Full Text Available Apoptosis mediated by Bax or Bak is usually thought to be triggered by BH3-only members of the Bcl-2 protein family. BH3-only proteins can directly bind to and activate Bax or Bak, or indirectly activate them by binding to anti-apoptotic Bcl-2 family members, thereby relieving their inhibition of Bax and Bak. Here we describe a third way of activation of Bax/Bak dependent apoptosis that does not require triggering by multiple BH3-only proteins. In factor dependent myeloid (FDM cell lines, cycloheximide induced apoptosis by a Bax/Bak dependent mechanism, because Bax-/-Bak-/- lines were profoundly resistant, whereas FDM lines lacking one or more genes for BH3-only proteins remained highly sensitive. Addition of cycloheximide led to the rapid loss of Mcl-1 but did not affect the expression of other Bcl-2 family proteins. In support of these findings, similar results were observed by treating FDM cells with the CDK inhibitor, roscovitine. Roscovitine reduced Mcl-1 abundance and caused Bax/Bak dependent cell death, yet FDM lines lacking one or more genes for BH3-only proteins remained highly sensitive. Therefore Bax/Bak dependent apoptosis can be regulated by the abundance of anti-apoptotic Bcl-2 family members such as Mcl-1, independently of several known BH3-only proteins.

Dysregulation of the “intrinsic” apoptotic pathway is associated with the development of cancer and autoimmune disease. Bak and Bax are two proapoptotic members of the Bcl-2 protein family with overlapping, essential roles in the intrinsic apoptotic pathway. Their activity is critical for the control of cell survival during lymphocyte development and homeostasis, best demonstrated by defects in thymic T-cell differentiation and peripheral lymphoid homeostasis caused by their combined loss. Because most bak−/−bax−/− mice die perinatally, the roles of Bax and Bak in immunological tolerance and prevention of autoimmune disease remain unclear. We show that mice reconstituted with a Bak/Bax doubly deficient hematopoietic compartment develop a fatal systemic lupus erythematosus-like autoimmune disease characterized by hypergammaglobulinemia, autoantibodies, lymphadenopathy, glomerulonephritis, and vasculitis. Importantly, these mice also develop a multiorgan autoimmune disease with autoantibodies against most solid glandular structures and evidence of glandular atrophy and necrotizing vasculitis. Interestingly, similar albeit less severe pathology was observed in mice containing a hematopoietic compartment deficient for only Bak, a phenotype reminiscent of the disease seen in patients with point mutations in BAK. These studies demonstrate a critical role for Bak and an ancillary role for Bax in safeguarding immunological tolerance and prevention of autoimmune disease. This suggests that direct activators of the intrinsic apoptotic pathway, such as BH3 mimetics, may be useful for treatment of diverse autoimmune diseases. PMID:23349374

Conjunctiva-associated lymphoid tissue (CALT) is closely associated with ocular surface immunity. This study investigated the effects of antiglaucoma prostaglandin analogs with or without benzalkonium chloride (BAK) preservative on organized CALT using an acute toxic model. A total of 48 albino rabbits were used and seven groups of treatments were constituted. Solutions (50 µl) of PBS, 0.02%BAK, 0.02%BAK+latanoprost, 0.015%BAK+travoprost, 0.005%BAK+bimatoprost, BAK-freetravoprost preserved with the SofZia® system or BAK-freetafluprost were instilled 15 times at 5-min intervals in both eyes. CALT changes were analyzed using in vivo confocal microscopy (IVCM), immunohistology in cryosections for detecting MUC-5AC+ mucocytes and CD45+ hematopoietic cells. Antiglaucoma eye drops stimulated inflammatory cell infiltration in the CALT, and seemed to be primarily related to the concentration of their BAK content. The CALT reaction after instillation of BAK-containing eye drops was characterized by inflammatory cell infiltration in the dome and intrafollicular layers and by cell circulation inside the lymph vessels. CD45 was strongly expressed in the CALT after instillation of all BAK-containing solutions at 4 h and decreased at 24 h. The number of MUC-5AC+ mucocytes around the CALT structure decreased dramatically after instillation of BAK-containing solutions. This study showed for the first time the in vivo aspect of rabbit CALT after toxic stimuli, confirming the concentration-dependent toxic effects of BAK. IVCM-CALT analysis could be a pertinent tool in the future for understanding the immunotoxicologic challenges in the ocular surface and would provide useful criteria for evaluating newly developed eye drops.

Full Text Available The plasma membrane-localized BRI1-ASSOCIATED KINASE1 (BAK1 functions as a co-receptor with several receptor kinases including the brassinosteroid (BR receptor BRASSINOSTEROID-INSENSITIVE 1 (BRI1, which is involved in growth, and the receptors for bacterial flagellin and EF-Tu, FLAGELLIN-SENSING 2 (FLS2 and EF-TU RECEPTOR (EFR, respectively, which are involved in immunity. BAK1 is a dual specificity protein kinase that can autophosphorylate on serine, threonine and tyrosine residues. It was previously reported that phosphorylation of Tyr-610 in the carboxy-terminal domain of BAK1 is required for its function in BR signaling and immunity. However, the functional role of Tyr-610 in vivo has recently come under scrutiny. Therefore, we have generated new BAK1 (Y610F transgenic plants for functional studies. We first produced transgenic Arabidopsis lines expressing BAK1 (Y610F-Flag in the homozygous bak1-4 bkk1-1 double null background. In a complementary approach, we expressed untagged BAK1 and BAK1 (Y610F in the bak1-4 null mutant. Neither BAK1 (Y610F transgenic line had any obvious growth phenotype when compared to wild-type BAK1 expressed in the same background. In addition, the BAK1 (Y610F-Flag plants responded similarly to plants expressing BAK1-Flag in terms of brassinolide (BL inhibition of root elongation, and there were only minor changes in gene expression between the two transgenic lines as monitored by microarray analysis and quantitative real-time PCR. In terms of plant immunity, there were no significant differences between plants expressing BAK1 (Y610F-Flag and BAK1-Flag in the growth of the non-pathogenic hrpA- mutant of Pseudomonas syringae pv. tomato DC3000. Furthermore, untagged BAK1 (Y610F transgenic plants were as responsive as plants expressing BAK1 (in the bak1-4 background and wild-type Col-0 plants toward treatment with the EF-Tu- and flagellin-derived peptide epitopes elf18- and flg22, respectively, as measured by reactive

N-(1-Pyrenyl Maleimide Induces Bak Oligomerization and Mitochondrial Dysfunction in Jurkat Cells

2015-01-01
Full Text Available N-(1-pyrenyl maleimide (NPM is a fluorescent reagent that is frequently used as a derivatization agent for the detection of thio-containing compounds. NPM has been shown to display a great differential cytotoxicity against hematopoietic cancer cells. In this study, the molecular mechanism by which NPM induces apoptosis was examined. Here, we show that treatment of Jurkat cells with NPM leads to Bak oligomerization, loss of mitochondrial membrane potential (Δψm, and release of cytochrome C from mitochondria to cytosol. Induction of Bak oligomerization appears to play a critical role in NPM-induced apoptosis, as downregulation of Bak by shRNA significantly prevented NPM-induced apoptosis. Inhibition of caspase 8 by Z-IETD-FMK and/or depletion of Bid did not affect NPM-induced oligomerization of Bak. Taken together, these results suggest that NPM-induced apoptosis is mediated through a pathway that is independent of caspase-8 activation.

Overview of the [corrected] travoprost /timolol BAK-free fixed combination.
Konstas, Anastasios G P; Quaranta, Luciano; Realini, Tony
2012-04-01
Glaucoma is the second leading cause of blindness globally, representing a significant public health concern. More than 60 million people are affected by glaucoma worldwide; as this population ages, the number is expected to increase. Glaucoma is a collection of heterogeneous diseases sharing common clinical characteristics. The goal of treatment is to prevent significant visual dysfunction through reduction of intraocular pressure (IOP). This is a review of the current literature about combination therapeutic regimens for the reduction of IOP, focusing on the risk : benefit profile of a fixed-combination therapy using travoprost and timolol. Since the debut of prostaglandin analogues in the 1990s, only modest innovation has occurred in glaucoma pharmacology. A growing body of research has established that the preservative benzalkonium chloride (BAK) might not be the benign contributor expected of excipient ingredients. Thus, BAK-free treatments were developed, with the goal of IOP reduction without furthering ocular surface disease symptoms.

Aberrant apoptosis can lead to acute or chronic degenerative diseases. Mitochondrial outer membrane permeabilization (MOMP) triggered by the oligomerization of the Bcl-2 family proteins Bax/Bak is an irreversible step leading to execution of apoptosis. Here, we describe the discovery of small-molecule inhibitors of Bax/Bak oligomerization that prevent MOMP. We demonstrate that these molecules disrupt multiple, but not all, interactions between Bax dimer interfaces thereby interfering with the formation of higher-order oligomers in the MOM, but not recruitment of Bax to the MOM. Small-molecule inhibition of Bax/Bak oligomerization allowed cells to evade apoptotic stimuli and rescued neurons from death after excitotoxicity, demonstrating that oligomerization of Bax is essential for MOMP. Our discovery of small-molecule Bax/Bak inhibitors provides novel tools for the investigation of the mechanisms leading to MOMP and will ultimately facilitate development of compounds inhibiting Bax/Bak in acute and chronic degenerative diseases.

Full Text Available Braya humilis (Brassicaceae is a widely distributed plant in arid and semi-arid regions of northern Asia. This plant is well adapted to extremely arid conditions and is a promising candidate species to discover novel drought tolerance strategies. However, not much information about the mechanism(s mediating drought resistance in this species is currently available. Therefore, the present study aimed to characterize the physiological traits and expression patterns of a polyethylene glycol (PEG-responsive gene in B. humilis responding to different levels of osmotic stress induced by PEG-6000. Several important physiological parameters were examined, including the levels of relative water content, soluble protein, malondialdehyde, and antioxidant enzyme activity. A tolerance threshold between 20 and 30% PEG-6000 was identified for B. humilis. The water status and oxidative damage below this threshold were maintained at a relatively constant level during the 12 h of treatment. However, once the threshold was exceeded, the water status and oxidative damage were obviously affected after treatment for 4 h. The soluble protein results suggest that B. humilis maintains a vigorous resistance to osmotic stress and that it may play a greater role in osmotic regulation at late stages of stress. Moreover, superoxide dismutase and catalase may be important at preventing oxidative damage in plants at early stages of stress, while peroxidase may be more involved in some biological processes that resist osmotic stress at the late stage, especially in severely damaged plants. Furthermore, a PEG-responsive gene, BhCIPK12, was identified by differential display reverse transcription-polymerase chain reaction (PCR, cloned, and characterized by quantitative real-time PCR. We hypothesized that this gene may play an important role in mediating osmotic stress or drought resistance in plants. Altogether, these results provide valuable insights into the mechanism

2015-01-01
In silico analysis predicts interaction between Na-K-ATPase (NKA) and Bcl-2 protein canonical BH3- and BH1-like motifs, consistent with NKA inhibition by the benzo-phenanthridine alkaloid chelerythrine, a BH3 mimetic, in fetal human lens epithelial cells (FHLCs) (Lauf PK, Heiny J, Meller J, Lepera MA, Koikov L, Alter GM, Brown TL, Adragna NC. Cell Physiol Biochem 31: 257-276, 2013). This report establishes proof of concept: coimmunoprecipitation and immunocolocalization showed unequivocal and direct physical interaction between NKA and Bcl-2 proteins. Specifically, NKA antibodies (ABs) coimmunoprecipitated BclXL (B-cell lymphoma extra large) and BAK (Bcl-2 antagonist killer) proteins in FHLCs and A549 lung cancer cells. In contrast, both anti-Bcl-2 ABs failed to pull down NKA. Notably, the molecular mass of BAK1 proteins pulled down by NKA and BclXL ABs appeared to be some 4-kDa larger than found in input monomers. In silico analysis predicts these higher molecular mass BAK1 proteins as alternative splicing variants, encoding 42 amino acid (aa) larger proteins than the known 211-aa long canonical BAK1 protein. These BAK1 variants may constitute a pool separate from that forming mitochondrial pores by specifically interacting with NKA and BclXL proteins. We propose a NKA-Bcl-2 protein ternary complex supporting our hypothesis for a special sensor role of NKA in Bcl-2 protein control of cell survival and apoptosis.

Full Text Available Benzalkonium chloride (BAK is a cationic detergent with a very slow turnover. Because of its strong antibacterial activities, BAK is widely used especially in dentistry and ophthalmology. It is the most commonly used preservative in topical ophthalmic medications. Due to chronicity and widespread use of such treatments, BAK’s side effects are of great importance. BAK toxicity for adherent cells, probably related to its pro-oxidative activities, is time- and dose-dependent. Although lymphocytes often infiltrate superficial eye tissues, the BAK influence on them is yet to be established. The aim of this study was to check BAK cytotoxicity on T lymphocytic Jurkat line cells and to verify the suggestion that BAK can induce G2M cell blocks. A dose- and time-dependent cytotoxic effect of BAK on lymphoid cells in relatively low concentrations was shown in this study. In lower concentrations, it shows a moderate apoptotic and minimal antiproliferative effect on Jurkat cells, while in higher concentrations it shows a rapid necrotic effect. No G2M cell blocks were observed. Our findings could suggest lymphoid dysfunction during intensive, prolonged topical BAK treatment, even at dosages relatively non-toxic to epithelial eye cells.

Paclitaxel-induced apoptosis is BAK-dependent, but BAX and BIM-independent in breast tumor.
Directory of Open Access Journals (Sweden)
Anna V Miller
Full Text Available Paclitaxel (Taxol-induced cell death requires the intrinsic cell death pathway, but the specific participants and the precise mechanisms are poorly understood. Previous studies indicate that a BH3-only protein BIM (BCL-2 Interacting Mediator of cell death plays a role in paclitaxel-induced apoptosis. We show here that BIM is dispensable in apoptosis with paclitaxel treatment using bim(-/- MEFs (mouse embryonic fibroblasts, the bim(-/- mouse breast tumor model, and shRNA-mediated down-regulation of BIM in human breast cancer cells. In contrast, both bak (-/- MEFs and human breast cancer cells in which BAK was down-regulated by shRNA were more resistant to paclitaxel. However, paclitaxel sensitivity was not affected in bax(-/- MEFs or in human breast cancer cells in which BAX was down-regulated, suggesting that paclitaxel-induced apoptosis is BAK-dependent, but BAX-independent. In human breast cancer cells, paclitaxel treatment resulted in MCL-1 degradation which was prevented by a proteasome inhibitor, MG132. A Cdk inhibitor, roscovitine, blocked paclitaxel-induced MCL-1 degradation and apoptosis, suggesting that Cdk activation at mitotic arrest could induce subsequent MCL-1 degradation in a proteasome-dependent manner. BAK was associated with MCL-1 in untreated cells and became activated in concert with loss of MCL-1 expression and its release from the complex. Our data suggest that BAK is the mediator of paclitaxel-induced apoptosis and could be an alternative target for overcoming paclitaxel resistance.

Icons of Just Is: Justice, Suffering, and the Artwork of Samuel Bak
Directory of Open Access Journals (Sweden)
Gary A. Phillips
2017-06-01
Full Text Available This paper examines select paintings by Holocaust survivor and painter Samuel Bak from his recent Just Is series. The essay explores ways Bak’s art bears witness to suffering. He creatively interrogates and reanimates the iconic figure of Lady Justice and the biblical principle of the lex talionis (“eye for an eye” in order to fashion alternative icons fit for an age of atrocity and loss. Bak’s artwork gives visual expression to Theodor Adorno’s view of the precariousness of art after Auschwitz. It is art’s responsibility to attend to the burden of real suffering experiences (the burden of the empirical and to think in contradictions, which renders art both adequate and inadequate in standing up against the injustice of other’s suffering. Through inventive juxtaposition of secular and sacred symbols, Bak displays the paradox of representation after the Holocaust and art’s precarious responsibility giving voice to suffering. Bak fashions visual spaces in which barbarity and beauty coincide and collide. He invites viewers into this space and into dialogue about justice’s standing and promises. Do Bak's remade icons of Just Is lament a permanent loss of justice and peace, or do they point tentatively to possibilities of life lived in a damaged world with an alternative Just Is? Bak’s artwork prompts such vexing questions for his viewers to contemplate and leaves them to decide what must be done.

Marina Ariza
2017-01-01
Full Text Available On the basis of 12 in-depth interviews with Dominican immigrant workers in the low reproductive sectors in Madrid in 2014 (domestic service and care, a description is provided of the place occupied by shame, pride and humiliation as key social emotions. From a sociological perspective, these emotions constitute a kind of gyroscope that reports on the status of social ties, as well as the quality of structurally-rooted social interaction. Humiliation, a darker version of shame, has been linked to migration due to the socially degraded jobs immigrants often perform. Although in contexts of acute social asymmetry, the condition of service inherent to domestic and care work often entails painful feelings, the success of the family economic project as well as small achievements in the field of employment constitute a source of deep satisfaction for immigrant women.

Sugars function as signal molecules to regulate growth, development, and gene expression in plants, yeasts, and animals. A coordination of sugar availability with phytohormone signals is crucial for plant growth and development. The molecular link between sugar availability and hormone-dependent plant growth are largely unknown. Here we report that BRI1 and BAK1 are involved in sugar-responsive growth and development. Glucose influences the physical interactions and phosphorylations of BRI1 and BAK1 in a concentration-dependent manner. BRI1 and BAK1 physically interact with G proteins that are essential for mediating sugar signaling. Biochemical data show that BRI1 can phosphorylate G protein β subunit and γ subunits, and BAK1 can phosphorylate G protein γ subunits. Genetic analyses suggest that BRI1 and BAK1 function in a common pathway with G-protein subunits to regulate sugar responses. Thus, our findings reveal an important genetic and molecular mechanism by which BR receptors associate with G proteins to regulate sugar-responsive growth and development.

Purpose: To address in vivo the issue of whether Bax and Bak are functionally redundant in signaling apoptosis, capable of substituting for each other. Methods and Materials: Mice were exposed to whole-body radiation, and endothelial cell apoptosis was quantified using double immunostaining with TUNEL and anti-CD31 antibody. Crypt survival was determined at 3.5 days after whole-body radiation by the microcolony survival assay. Actuarial animal survival was calculated by the product-limit Kaplan-Meier method, and autopsies were performed to establish cause of death. Results: Radiation exposure of Bax- and Bak-deficient mice, both expressing a wild-type acid sphingomyelinase (ASMase) phenotype, indicated that Bax and Bak are both mandatory, though mutually independent, for the intestinal endothelial apoptotic response. However, neither affected epithelial apoptosis at crypt positions 4-5, indicating specificity toward endothelium. Furthermore, Bax deficiency and Bak deficiency each individually mimicked ASMase deficiency in inhibiting crypt lethality in the microcolony assay and in rescuing mice from the lethal gastrointestinal syndrome. Conclusions: The data indicate that Bax and Bak have nonredundant functional roles in the apoptotic response of the irradiated intestinal endothelium. The observation that Bax deficiency and Bak deficiency also protect crypts in the microcolony assay provides strong evidence that the microvascular apoptotic component is germane to the mechanism of radiation-induced damage to mouse intestines, regulating reproductive cell death of crypt stem cell clonogens

To assess the efficacy and tolerability of benzalkonium chloride (BAK)-free travoprost after transition from BAK-preserved latanoprost. This was a prospective, open-label, multicenter study in patients with open-angle glaucoma or ocular hypertension who had been treated with latanoprost monotherapy for at least 3 months. The main outcome measures were superficial punctate keratopathy (SPK), hyperemia, and intraocular pressure (IOP). At baseline, 1, 3, and 12 months, hyperemia, SPK, and IOP were consecutively assessed. Hyperemia was assessed using a 4-grade scale. SPK was assessed by fluorescence staining observed by Area-Density classification. The IOP was measured by Goldmann applanation tonometry. One hundred and fourteen patients participated in this study. Twenty-eight patients discontinued medications by 1 month. Sixty-seven patients completed the study. Transition from latanoprost to BAK-free travoprost showed no significant effect on hyperemia at 1 month, but showed significant decreases at 3 and 12 months compared with baseline (Preduction after the change in regimen compared with baseline (P<0.05). Treatment for 12 months with BAK-free travoprost after BAK-preserved latanoprost resulted in fewer ocular surface complications, as indicated by the reduced prevalence of SPK and decreased hyperemia, and no clinically relevant changes in IOP. BAK-free travoprost may have beneficial effects on the ocular surface while showing IOP-lowering efficacy comparable with BAK-preserved eye drops.

The Injured Body: Humiliation and Fragmentation

Full Text Available Simone de Beauvoir’s nouvelles and Titus Andronicus by Shakespeare present us opposite and complementary corporeal nature. In the first case, two women about their sixties are in front of the personal drama of their lost which happen through the years of ageing. It is a kind of fragmentation of existence. Ageing is the most authentic state of the human condition because the human being can only hang on to himself. In Titus Andronicus, are shown mutilations, murderers as fragmentation of biological body and social body. Individualism of modernity doesn’t forgive the bodies deteriorated by the years. In the early modernity, in the times of Elizabeth the First, like in the Ancient Rome, it wasn’t spared humiliations and violence towards the enemy body in order to impose power and authority. In this Shakespeare’s play, the fragmentation of the other’s body and murder are the emergence of social and individual violence.

The cytoplasmic domain of BRI1-associated kinase 1 from A. thaliana has been overexpressed in E. coli, purified and crystallized. Diffraction data were collected to 2.6 Å resolution. BRI1-associated kinase 1 (BAK1) is a member of the plant receptor-like kinase (RLK) superfamily. BAK1 has been shown to initiate brassinosteroid (BR) signalling and innate immune responses in plants by forming receptor complexes with both brassinosteroid-insensitive 1 (BRI1) and flagellin-sensing 2 (FLS2). To gain a better understanding of the structural details and the mechanism of action of the BAK1 kinase domain, recombinant BAK1 cytoplasmic domain has been expressed, purified and crystallized at 291 K using PEG 3350 as a precipitant.

To understand the molecular mechanisms that underlie radiation pneumonitis, we examined whether knockout of the tumor necrosis factor (TNF) or the interleukin (IL)-6 gene could give mice an inherent resistance to radiation in the acute phase of alveolar damage after thoracic irradiation. The temporal expression of inflammation (CD44) and apoptosis (Bak) markers in lung after thoracic irradiation was measured to determine the degree of alveolar damage. At 4 weeks post-irradiation (10 Gy), small inflammatory foci were observed in all mice, but there were no obvious histological differences between control (C57BL/6JSlc), TNF-alpha knockout (TNF KO), and IL-6 knockout (IL-6 KO) mice. However, immunohistochemical analysis of CD44 and Bak expression over a time course of 2 weeks highlighted significant differences between the three groups. C57BL/6JSlc and TNF KO mice had increased numbers of both CD44-positive and Bak-positive cells after irradiation, while the IL-6 KO mice showed stable levels of CD44 and Bak. In conclusion, the radioresistant status of IL-6 KO mice in the acute phase of alveolar damage after irradiation suggested an important role for IL-6 in radiation pneumonitis. (author)

To understand the ecology and physiology of metal-accumulating lichens growing in Cu-polluted sites, we investigated lichens near temple and shrine buildings with Cu roofs in Japan and found that Stereocaulon japonicum Th. Fr. and Cladonia humilis (With.) J. R. Laundon grow in Cu-polluted sites. Metal concentrations in the lichen samples collected at some of these sites were determined by inductively coupled plasma mass spectroscopy (ICP-MS). UV-vis absorption spectra of pigments extracted from the lichen samples were measured, and the pigment concentrations were estimated from the spectral data using equations from the literature. Secondary metabolites extracted from the lichen samples were analyzed by high-performance liquid chromatography (HPLC) with a photodiode array detector. We found that S. japonicum and C. humilis are Cu-hyperaccumulating lichens. Differences in pigment concentrations and their absorption spectra were observed between the Cu-polluted and control samples of the 2 lichens. However, no correlation was found between Cu and pigment concentrations. We observed a positive correlation between Al and Fe concentrations and unexpectedly found high negative correlations between Al and pigment concentrations. This suggests that Al stress reduces pigment concentrations. The concentrations of secondary metabolites in C. humilis growing in the Cu-polluted sites agreed with those in C. humilis growing in the control sites. This indicates that the metabolite concentrations are independent of Cu stress. Copyright © 2013 Elsevier Inc. All rights reserved.

Giant clams live in nutrient-poor reef waters of the Indo-Pacific and rely on symbiotic dinoflagellates ( Symbiodinium spp., also known as zooxanthellae) for nutrients. As the symbionts are nitrogen deficient, the host clam has to absorb exogenous nitrogen and supply it to them. This study aimed to demonstrate light-enhanced urea absorption in the fluted giant clam, Tridacna squamosa , and to clone and characterize the urea active transporter DUR3-like from its ctenidium (gill). The results indicate that T. squamosa absorbs exogenous urea, and the rate of urea uptake in the light was significantly higher than that in darkness. The DUR3-like coding sequence obtained from its ctenidium comprised 2346 bp, encoding a protein of 782 amino acids and 87.0 kDa. DUR3-like was expressed strongly in the ctenidium, outer mantle and kidney. Twelve hours of exposure to light had no significant effect on the transcript level of ctenidial DUR3-like However, between 3 and 12 h of light exposure, DUR3-like protein abundance increased progressively in the ctenidium, and became significantly greater than that in the control at 12 h. DUR3-like had an apical localization in the epithelia of the ctenidial filaments and tertiary water channels. Taken together, these results indicate that DUR3-like might participate in light-enhanced urea absorption in the ctenidium of T. squamosa When made available to the symbiotic zooxanthellae that are known to possess urease, the absorbed urea can be metabolized to NH 3 and CO 2 to support amino acid synthesis and photosynthesis, respectively, during insolation. © 2018.

Apoptosis of cochlear cells is an important factor in animal models of ARHI. As these cells cannot regenerate, their loss leads to irreversible hearing impairment. Identification of molecular mechanisms can facilitate disease prevention and effective treatment. In this study, we compared the expression of the genes BAK1 and BCL2 as two arms of the intrinsic apoptosis pathway between patients with ARHI and healthy subjects. ARHI and healthy subjects were selected after an ear nose throat examination, otoscopic investigation, and pure tone audiometry. RNA was extracted from peripheral blood samples, and relative gene expression levels were measured using quantitative real-time polymerase chain reaction. BAK1 and the BAK1/BCL2 ratio were statistically significantly upregulated in the ARHI subjects. The BAK1/BCL2 ratio was positively correlated with the results of the audiometric tests. Our results indicate that BAK-mediated apoptosis may be a core mechanism in the progression of ARHI in humans, similar to finding in animal models. Moreover, the gene expression changes in peripheral blood samples could be used as a rapid and simple biomarker for early detection of ARHI.

Medical miracles and the longue durée.
Duffin, Jacalyn
2005-01-01
The hematologist-historian author became interested in the nature 'medical miracles', following a request to write a report on a set of bone marrows that was sent to the Vatican as a possible miracle cure in a cause for canonization. She questioned the prevalence of medical miracles, their structure, and relationship to other 'official' miracles that are recognized by the Church. Evidence was drawn from a variety of sources: oral testimony of pilgrims at feast day celebrations, ex voto paintings, and 160 miracle files in 67 canonization records of the Vatican Archives. Some changes can be detected through time, but the results also testify to remarkable longue durée in the healing experience: the patterns of suffering and despair, the gestures of pleading, the presence of beds and dreams, the astonishment of the caregivers, and above all the simultaneous recourse to medicine and religion both.

The first layer of plant immunity is activated by cell surface receptor-like kinases (RLKs) and proteins (RLPs) that detect infectious pathogens. Constitutive interaction with the SUPPRESSOR OF BIR1 (SOBIR1) RLK contributes to RLP stability and kinase activity. As RLK activation requires transphosphorylation with a second associated RLK, it remains elusive how RLPs initiate downstream signaling. We employed live-cell imaging, gene silencing and coimmunoprecipitation to investigate the requirement of associated kinases for functioning and ligand-induced subcellular trafficking of Cf RLPs that mediate immunity of tomato against Cladosporium fulvum. Our research shows that after elicitation with matching effector ligands Avr4 and Avr9, BRI1-ASSOCIATED KINASE 1/SOMATIC EMBRYOGENESIS RECEPTOR KINASE 3 (BAK1/SERK3) associates with Cf-4 and Cf-9. BAK1/SERK3 is required for the effector-triggered hypersensitive response and resistance of tomato against C. fulvum. Furthermore, Cf-4 interacts with SOBIR1 at the plasma membrane and is recruited to late endosomes upon Avr4 trigger, also depending on BAK1/SERK3. These observations indicate that RLP-mediated resistance and endocytosis require ligand-induced recruitment of BAK1/SERK3, reminiscent of BAK1/SERK3 interaction and subcellular fate of the FLAGELLIN SENSING 2 (FLS2) RLK. This reveals that diverse classes of cell surface immune receptors share common requirements for initiation of resistance and endocytosis. © 2016 The Authors.

Six parenteral third generation cephalosporins have been introduced into clinical use in the past 10 years. The 3 most frequently available agents are cefotaxime, ceftriaxone and ceftazidime. These 3 third generation cephalosporins are characterised by a broad spectrum of activity and increased stability to beta-lactamases compared with the first and second generation cephalosporins. However, there are growing numbers of reports of resistance to these agents with increasing use. The major differences in the properties of the 3 agents are the long half-life of ceftriaxone and its dual route of elimination. Ceftazidime is best restricted to Pseudomonas aeruginosa infections where other agents are contraindicated or ineffective. Cefotaxime and ceftriaxone can be used in nosocomial Gram-negative infections where P. aeruginosa can be ruled out. The types and incidences of adverse drug reactions are not different for the 3 agents. A number of drug utilisation review (DUR) studies of these agents in the hospital setting have reported a considerable incidence of inappropriate use and substantial avoidable costs. There are methodological problems with most of the DUR studies, especially the criteria and the methods of cost estimation. The use of pharmacoeconomic methodology could ensure more realistic cost estimation; however, outcome data are, in most cases, not available.

Benzalkonium chloride (BAK), a common preservative in eye drops, can induce ocular surface toxicity that may decrease glaucoma therapy compliance. The ocular hypotensive effect, pharmacokinetic (PK) profiles, and local tolerance of a preservative-free latanoprost 0.005% cationic emulsion (Catioprost(®)), and a BAK-preserved latanoprost 0.005% solution (Xalatan(®)), were compared. The ocular hypotensive effect was evaluated in monkeys with elevated intraocular pressure (IOP) induced by laser photocoagulation of the trabecular meshwork. Each monkey (n=8) received both latanoprost formulations once daily for 5 consecutive treatment days in a crossover design with at least a 2-week washout period between treatments. IOP was measured at baseline (on day 1, no instillation), on vehicle treatment day (day 0), and on treatment days 1, 3, and 5 before drug instillation and then hourly for 6 h. In rabbits, the ocular and systemic concentrations of latanoprost free acid were determined following a single instillation and the local tolerance of twice daily instillations over 28 days was assessed. Both the preservative-free and BAK-preserved latanoprost formulations shared the same efficacy profile with the maximum IOP reduction occurring 2 h after each morning dose (-15%, -20%, and -26%; -15%, -23%, and -23% on days 1, 3, and 5, respectively) and lasting through 24 h. The equivalence in efficacy was confirmed by the PK data demonstrating similar area under the curves (AUCs). While both formulations were well tolerated, the incidence of conjunctival hyperemia was reduced by 42% with the BAK-free latanoprost cationic emulsion. In animal models, a preservative-free latanoprost cationic emulsion was as effective as Xalatan(®) for lowering IOP with an improved ocular tolerance profile.

Full Text Available Objective: To evaluate the pesticidal activity of antifeedant, oviposition deterrent, ovicidal and larvicidal activities of benzene, dichloromethane, diethylether, ethylacetate and methanol extracts of Rivina humilis at different concentrations against agricultural polyphagous pest Spodoptera litura (Lepidoptera: Noctuidae (S. litura. Methods: Antifeedant activities of the selected plant extract were studied as described by Isman et al. (1990, with slight modifications. For oviposition deterrent activity, ten pairs of (adult moths S. litura were subjected in five replicates. After 48 h, the numbers of eggs masses laid on treated and control leaves were recorded and the percentage of oviposition deterrence was calculated. The ovicidal activity was determined against the eggs of S. litura. Twenty five early fourth instar larvae of S. litura were exposed to various concentrations and was assayed by using the protocol of Abbott’s formula (1925; the 24 h LC50 values of the Rivina humilis leaf extract was determined by probit analysis. Results: All the extracts showed moderate antifeedant activitiy; however, significant antifeedant, ovicidal, oviposition deterrent and larvicidal activities were observed in methanol extract. Conclusions: This study showed that the selected plant can be a potent source of natural antifeedant, oviposition deterrent, ovicidal and larvicidal activities against field pest S. litura.

Abstract In newly invaded communities, interspecific competition is thought to play an important role in determining the success of the invader and its impact on the native community. In southern Australia, the native Polistes humilis was the predominant social wasp prior to the arrival of the exotic Vespula germanica (Hymenoptera: Vespidae). Both species forage for similar resources (water, pulp, carbohydrate and protein prey), and concerns have arisen about potential competition between them. The aim of this study was to identify the protein foods that these wasps feed on. As many prey items are masticated by these wasps to the degree that they cannot be identified using conventional means, morphological identification was complemented by sequencing fragments of the mitochondrial 16S rRNA gene. GenBank searches using blast and phylogenetic analyses were used to identify prey items to at least order level. The results were used to construct complete prey inventories for the two species. These indicate that while P. humilis is restricted to feeding on lepidopteran larvae, V. germanica collects a variety of prey of invertebrate and vertebrate origin. Calculated values of prey overlap between the two species are used to discuss the implications of V. germanica impacting on P. humilis. Results obtained are compared to those gained by solely 'conventional' methods, and the advantages of using DNA-based taxonomy in ecological studies are emphasized.

Full Text Available Non-native ascidians are important members of the fouling community associated with artificial substrata and man-made structures. Being efficient fouling species, they are easily spread by human-mediated transports (e.g., with aquaculture trade and maritime transports. This is exemplified by the ascidian Asterocarpa humilis which displays a wide distribution in the Southern Hemisphere and has been recently reported in the Northern Hemisphere (NW Europe. In continental Chile, its first report dates back from 2000 for the locality of Antofagasta (23°S. Although there was no evidence about the vectors of introduction and spread, nor the source, some authors suggested maritime transport by ship hulls and aquaculture devices as putative introduction pathways and vectors. In the present study, we report for the first time the presence of A. humilis on the hull of an international ship in a commercial port in Concepción bay (36°S, south central Chile. We also found one individual associated to a seashell farm, 70 km far from Concepción bay. Further individuals were subsequently identified within Concepción bay: one juvenile settled upon international harbor pilings and a dozen individuals along aquaculture seashell longlines. For the first specimens sampled, species identification was ascertained using both morphological criteria and molecular barcoding, using the mitochondrial gene cytochrome c oxidase subunit I (COI and a nuclear gene (ribosomal RNA 18S. The nuclear 18S gene and the mitochondrial gene COI clearly assigned the specimens to A. humilis, confirming our morphological identification. Two haplotypes were obtained with COI corresponding to haplotypes previously obtained with European and Northern Chilean specimens. The present study thus reports for the first time the presence of A. humilis in the Araucanian ecoregion, documenting the apparent expansion of this non-native tunicate in Chile over 2,000 km, spanning over three ecoregions

Disruption of protein folding in the endoplasmic reticulum (ER) causes ER stress. Activation of the unfolded protein response (UPR) acts to restore protein homeostasis or, if ER stress is severe or persistent, drive apoptosis, which is thought to proceed through the cell intrinsic, mitochondrial pathway. Indeed, cells that lack the key executioner proteins BAX and BAK are protected from ER stress-induced apoptosis. Here we show that chronic ER stress causes the progressive inhibition of the extracellular signal-regulated kinase (ERK1/2) signalling pathway. This is causally related to ER stress since reactivation of ERK1/2 can protect cells from ER stress-induced apoptosis whilst ERK1/2 pathway inhibition sensitises cells to ER stress. Furthermore, cancer cell lines harbouring constitutively active BRAFV600E are addicted to ERK1/2 signalling for protection against ER stress-induced cell death. ERK1/2 signalling normally represses the pro-death proteins BIM, BMF and PUMA and it has been proposed that ER stress induces BIM-dependent cell death. We found no evidence that ER stress increased the expression of these proteins; furthermore, BIM was not required for ER stress-induced death. Rather, ER stress caused the PERK-dependent inhibition of cap-dependent mRNA translation and the progressive loss of pro-survival proteins including BCL2, BCLXL and MCL1. Despite these observations, neither ERK1/2 activation nor loss of BAX/BAK could confer long-term clonogenic survival to cells exposed to ER stress. Thus, ER stress induces cell death by at least two biochemically and genetically distinct pathways: a classical BAX/BAK-dependent apoptotic response that can be inhibited by ERK1/2 signalling and an alternative ERK1/2- and BAX/BAK-independent cell death pathway.

Many Haitian migrants live and work as undocumented laborers in the Dominican Republic. This study examines the legacy of anti-Haitian discrimination in the Dominican Republic and association of discrimination with mental health among Haitian migrants. This study used mixed methods to generate hypotheses for associations between discrimination and mental health of Haitian migrants in the Dominican Republic. In-depth interviews were conducted with 21 Haitian and 18 Dominican community members and clinicians. One hundred and twenty-seven Haitian migrants participated in a pilot cross-sectional community survey. Instruments included culturally adapted Kreyòl versions of the Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) and a locally developed function impairment scale. Haitian migrants described humiliation (imilyasyon) as a reason for mental distress and barrier to health care. Dominicans reported that discrimination (discriminación) was not a current social problem and attributed negative social interactions to sociocultural, behavioral, and biological differences between Dominicans and Haitians. These qualitative findings were supported in the quantitative analyses. Perceived discrimination was significantly associated with depression severity and functional impairment. Perceived mistreatment by Dominicans was associated with a 6.6-point increase in BDI score (90% confidence interval [CI]: 3.29, 9.9). Knowing someone who was interrogated or deported was associated with a 3.4-point increase in BAI score (90% CI: 0.22, 6.64). Both qualitative and quantitative methods suggest that perceived discrimination and the experience of humiliation contribute to Haitian migrant mental ill-health and limit access to health care. Future research should evaluate these associations and identify intervention pathways for both improved treatment access and reduction of discrimination-related health risk factors.

In Mediterranean-type ecosystems plants are exposed to several adverse environmental conditions throughout the year, ranging from drought stress during the warm and dry summers to chilling stress due to the typical drop in temperatures during winters. Here we evaluated the ecophysiological response, in terms of photoinhibition and photoprotection, of the dioecious Mediterranean palm, Chamaerops humilis to seasonal variations in environmental conditions. Furthermore, we considered as well the influence of plant size, maturity, and sexual dimorphism. Results showed evidence of winter photoinhibition, with a marked decrease of the F v /F m ratio below 0.7 between January and March, which was coincident with the lowest temperatures. During this period, the de-epoxidation state of the xanthophyll cycle and zeaxanthin levels increased, which might serve as a photoprotection mechanism, owing the full recovery from winter photoinhibition during spring. Furthermore, mature plants showed lower chlorophyll levels and higher β-carotene levels per unit of chlorophyll than juvenile plants, and females displayed lower leaf water contents and higher photoinhibition than males during summer, probably due to increased reproductive effort of females. However, neither low temperatures during winter nor reproductive events in females during the summer led to irreversible damage to the photosynthetic apparatus. We conclude that (i) the Mediterranean dwarf palm, C. humilis, suffers from photoinhibition during winter, but this is transient and does not lead to irreversible damage, and (ii) females from this plant species are more sensitive than males to photoinhibition during reproductive events.

Seventeen Chinese (Beijing) and 24 Japanese (Osaka) lung cancer cases were analyzed for mutations of p53, K-ras, β-catenin, c-kit and bak genes by PCR-SSCP analysis followed by direct sequencing. Significantly higher mutation frequency of p53 gene, one of key genes for radiation sensitivity, was found in Chinese cases (11/17; 64.7 %) than Japanese cases (8/24; 33.3 %) (p< O.O5). Fourteen of the 16 mutations found in the Chinese cases were transitions at exon 4,5 and intron 4. In the Japanese cases, of the total of 11 mutations, 5 were transitions and 5 were transversions and one was deletion. Six β-catenin mutations were found in 6 Chinese cases (35.3 % ) at codon 53 and 58, and 4 were found in 3 Japanese cases (12.5 %). C-kit mutations were detected in 5 Chinese cases (29.4 %), while no mutations were found in Japanese cases (p< O.O5). No K-ras mutation was found in both Chinese and Japanese cases. For the first time, we report on bak mutation in human lung cancer in Chinese (2/17; 11.8% ) and Japanese cases (2/24; 8.3% ). C-kit and bak genes are also definitive factors to radiosensitivity. These data thus suggest that there were apparent differences in frequency and/or mutational types of p53, β-catenin and c-kit? genes between Chinese and Japanese cases. The differences can be attributed to factors such as lifestyles including smoking and racial and/or environmental factors, and also to the prediction of the response to radiotherapy. (author)

Forms of Religious Glocalization: Orthodox Christianity in the Longue Durée
Directory of Open Access Journals (Sweden)
Victor Roudometof
2014-10-01
Full Text Available This article advocates a “glocal turn” in the religion–globalization problematic. It proposes a model of multiple glocalizations in order to analyze the historically constituted relationship between world religions and local cultures. First, the conceptual evolution from globalization to glocalization is discussed with special reference to the study of the religion. Second, the necessity for adopting the perspective of the longue durée with regard to the study of Eastern Orthodox Christianity is explained. Third, an outline of four forms of religious glocalization is proposed. Each of these forms is presented both analytically as well as through examples from the history of Eastern Christianity (from the 8th to the 21st century. It is argued that this approach offers a model for analyzing the relation between religion, culture and society that does not succumb to the Western bias inherent in the conventional narrative of western modernization and secularization.

Full Text Available Abstract: Education which emphasized on cognition domain should be changed by balancing it with skills (psychomotor and attitudes (affective. It is intended that education is able to produce savvy generations who have high moral standards. To that end, KH Abdurrahman Wahid -or better known as Gus Dur- had a concept of character building in education by promoting morality in education. Character building in education is the education which is based on local wisdom. Local wisdom is social norms and values contained in tradition and customs as well as in Islamic teachings that govern how a balance should be established between carrying capacity of the natural environment, lifestyle, and the needs of human beings. In the language of Gus Dur, local wisdom was called the indigenization of Islam in which the teachings of Islam and local traditions were used as a moral basis in the real life of people. Because the cultivation of moral values could be done through education, the local wisdom should be the basic concept of education process. Customs become an integral part in daily life, while religion becomes a way of life to conform to the guidance of Allah. Local wisdom formed from local traditions and locality of religious teachings was able to provide life lessons that were useful for the development process of maturity through the educational process. الملخص: إن التربية المفضّلة الجانب المعرفي – كما يقع الآن - لابد من تركها، ويكون البديل هو الموازنة بين الجانب المعرفي والجانب النفسحركي والمهني. والهدف من هذا تخريج الطلاب أو الأجيال الأذكياء المتأدّبين المتخلّقين. وفي هذا كان لكياهي الحاج عبد الرحمن وحيد المعروف بغوسدور فكرة عن التربية الخلقية وهي التربية التي

Pan-pan Girls: Humiliating Liberation in Postwar Japanese Literature
Directory of Open Access Journals (Sweden)

Full Text Available This paper looks at some literary representations of the ‘pan-pan girls’ in postwar Japan. ‘Pan-pan’ is a derogatory term for street prostitutes who (mostly served the soldiers of the occupying forces. Immediately after World War II, the Japanese government established the RAA (Recreation Amusement Association and employed several thousand women to provide sexual services for foreign soldiers, ostensibly to protect Japanese women of middle and upper classes from rape and other violence. When the RAA was closed down in 1946 due to the US concern over widespread VD, many of the women who lost their jobs went out on the street and became private and illegal prostitutes – the pan-pan girls. With their red lipstick, cigarettes, nylon stockings and high-heel shoes, often holding onto the arms of tall, uniformed American GIs, the ‘pan-pan girls’ became a symbol of the occupation, and have been textually reproduced throughout the postwar period. This paper analyses the images and representations of the ‘pan-pan girls’ in postwar Japanese literature, to consider how the ‘pan-pan girls’ have functioned as a metaphor for the occupation and contributed to the public memory construction of the occupation. I identify some major codes of representations (victimisation, humiliation, and national trauma; eroticism and decadence; sexual freedom and materialism and argue that the highly gendered and sexualised bodies of the ‘pan-pan girls’ have continued to allow simplistic and selective remembering of the occupation at the expense of recalling the pivotal role of Japanese patriarchy in the postwar period.

The structural motifs responsible for activation and regulation of eukaryotic protein kinases in animals have been studied extensively in recent years, and a coherent picture of their activation mechanisms has begun to emerge. In contrast, non-animal eukaryotic protein kinases are not as well understood from a structural perspective, representing a large knowledge gap. To this end, we investigated the conformational dynamics of two key Arabidopsis thaliana receptor-like kinases, brassinosteroid-insensitive 1 (BRI1) and BRI1-associated kinase 1 (BAK1), through extensive molecular dynamics simulations of their fully phosphorylated kinase domains. Molecular dynamics simulations calculate the motion of each atom in a protein based on classical approximations of interatomic forces, giving researchers insight into protein function at unparalleled spatial and temporal resolutions. We found that in an otherwise "active" BAK1 the αC helix is highly disordered, a hallmark of deactivation, whereas the BRI1 αC helix is moderately disordered and displays swinging behavior similar to numerous animal kinases. An analysis of all known sequences in the A. thaliana kinome found that αC helix disorder may be a common feature of plant kinases. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

Full Text Available Alonso Xuárez was no minor composer in the musical field of his time. The quality and effectiveness of his compositions makes them deserving of a leading place in Spanish and European music of the 17th century. In spite of this almost nothing is known about this composer prior to his being appointed to teach in the chapel of Cuenca cathedral. Virtually all the currently available data is of a secondary and collateral nature and arises from research into his disciple the organist Sebastián Durón, the renowned opera composer and teacher at the Capilla Real of Charles II.
Alonso Xuárez no fue un compositor menor dentro del panorama musical de su tiempo. La calidad y eficacia de su música merece estar en primera línea de la música española y europea del siglo XVII. Sin embargo, el desconocimiento de este músico es casi completo con anterioridad a su nombramiento en el magisterio de capilla de la catedral de Cuenca. Prácticamente todos los datos expuestos hasta el momento han sido restos secundarios y colaterales desprendidos de otras investigaciones realizadas sobre la figura de su discípulo, el reputado compositor de teatro lírico y maestro de la Capilla Real de Carlos II, el organista Sebastián Durón. -

A critical hallmark of cancer cell survival is evasion of apoptosis. This is commonly due to overexpression of anti-apoptotic proteins such as Bcl-2, Bcl-XL, and Mcl-1, which bind to the BH3 α-helical domain of pro-apoptotic proteins such as Bax, Bak, Bad, and Bim, and inhibit their function. We designed a BH3 α-helical mimetic BH3-M6 that binds to Bcl-XL and Mcl-1 and prevents their binding to fluorescently labeled Bak- or Bim-BH3 peptides in vitro. Using several approaches, we demonstrate that BH3-M6 is a pan-Bcl-2 antagonist that inhibits the binding of Bcl-XL, Bcl-2, and Mcl-1 to multi-domain Bax or Bak, or BH3-only Bim or Bad in cell-free systems and in intact human cancer cells, freeing up pro-apoptotic proteins to induce apoptosis. BH3-M6 disruption of these protein-protein interactions is associated with cytochrome c release from mitochondria, caspase-3 activation and PARP cleavage. Using caspase inhibitors and Bax and Bak siRNAs, we demonstrate that BH3-M6-induced apoptosis is caspase- and Bax-, but not Bak-dependent. Furthermore, BH3-M6 disrupts Bcl-XL/Bim, Bcl-2/Bim, and Mcl-1/Bim protein-protein interactions and frees up Bim to induce apoptosis in human cancer cells that depend for tumor survival on the neutralization of Bim with Bcl-XL, Bcl-2, or Mcl-1. Finally, BH3-M6 sensitizes cells to apoptosis induced by the proteasome inhibitor CEP-1612. PMID:21148306

The Bak-Sneppen model is an abstract representation of a biological system that evolves according to the Darwinian principles of random mutation and selection. The species in the system are characterized by a numerical fitness value between zero and one. We show that in the case of five species the steady-state fitness distribution can be obtained as a solution to a linear differential equation of order five with hypergeometric coefficients. Similar representations for the asymptotic fitness distribution in larger systems may help pave the way towards a resolution of the question of whether or not, in the limit of infinitely many species, the fitness is asymptotically uniformly distributed on the interval [fc, 1] with fc ≳ 2/3.

The present study is the first to report inhibition of breast cancer cell growth in vitro and in vivo and suppression of self-renewal of breast cancer stem cells (bCSC) by a pine bark component (leelamine). Except for a few recent publications in melanoma, anticancer pharmacology of this interesting phytochemical is largely elusive. Leelamine (LLM) dose-dependently inhibited viability of MDA-MB-231 (triple-negative), MCF-7 (estrogen receptor-positive), and SUM159 (triple-negative) human breast cancer cells in association with apoptotic cell death induction. To the contrary, a normal mammary epithelial cell line derived from fibrocystic breast disease and spontaneously immortalized (MCF-10A) was fully resistant to LLM-mediated cell growth inhibition and apoptosis induction. LLM also inhibited self-renewal of breast cancer stem cells. Apoptosis induction by LLM in breast cancer cells was accompanied by a modest increase in reactive oxygen species production, which was not due to inhibition of mitochondrial electron transport chain complexes. Nevertheless, ectopic expression of manganese superoxide dismutase conferred partial protection against LLM-induced cell death but only at a lower yet pharmacologically relevant concentration. Exposure of breast cancer cells to LLM resulted in (a) induction and/or activation of multidomain proapoptotic proteins Bax and Bak, (b) caspase-9 activation, and (c) cytosolic release of cytochrome c. Bax and Bak deficiency in immortalized fibroblasts conferred significant protection against cell death by LLM. Intraperitoneal administration of LLM (7.5 mg/kg; 5 times/wk) suppressed the growth of orthotopic SUM159 xenografts in mice without any toxicity. In conclusion, the present study provides critical preclinical data to warrant further investigation of LLM. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

A transient rise in cytosolic calcium ion concentration is one of the main signals used by plants in perception of their environment. The role of calcium in the detection of abiotic stress is well documented; however, its role during biotic interactions remains unclear. Here, we use a fluorescent calcium biosensor (GCaMP3) in combination with the green peach aphid (Myzus persicae) as a tool to study Arabidopsis thaliana calcium dynamics in vivo and in real time during a live biotic interaction. We demonstrate rapid and highly localized plant calcium elevations around the feeding sites of M. persicae, and by monitoring aphid feeding behavior electrophysiologically, we demonstrate that these elevations correlate with aphid probing of epidermal and mesophyll cells. Furthermore, we dissect the molecular mechanisms involved, showing that interplay between the plant defense coreceptor BRASSINOSTEROID INSENSITIVE-ASSOCIATED KINASE1 (BAK1), the plasma membrane ion channels GLUTAMATE RECEPTOR-LIKE 3.3 and 3.6 (GLR3.3 and GLR3.6), and the vacuolar ion channel TWO-PORE CHANNEL1 (TPC1) mediate these calcium elevations. Consequently, we identify a link between plant perception of biotic threats by BAK1, cellular calcium entry mediated by GLRs, and intracellular calcium release by TPC1 during a biologically relevant interaction.

Since apoptosis is impaired in malignant cells overexpressing pro-survival Bcl-2 proteins, drugs mimicking their natural antagonists, BH3-only proteins, might overcome chemoresistance. Of seven putative BH3 mimetics tested, only ABT-737 triggered Bax/Bak-mediated apoptosis. Despite its high affinity for Bcl-2, Bcl-xL and Bcl-w, many cell types proved refractory to ABT-737. We show that this resistance reflects its inability to target another pro-survival relative, Mcl-1. Down-regulation of Mc...

Background : People with non-epileptic seizures (NES) describe challenging relationships with health professionals, and explain negative interactions as common and expected. Despite these difficulties, little is known about how people with NES experience difficult healthcare encounters. Methods : Using a thematic discourse analysis approach, we analysed the free-text survey responses of 135 people with NES and asked: what kind of challenges do people living with this condition encounter when interacting with health professionals, and how do they experience the consequences of difficult interactions? We explore their experiences by interpreting the latent meaning of participants' texts from a social-constructionist perspective on health and illness. Results : The overarching narrative depicts a fundamental breakdown in patient-provider relationships. According to our data, the negative experiences of study participants emerge from more than practitioners' lack of awareness of NES and access to information about the condition - to the extent that it is available. In examining the challenges people with NES encounter when interacting with health professionals, their main experiences centre on blame and humiliation. When exploring their experiences, theories of stigma serve as a useful theoretical framework. Conclusions : Normative judgements arising from psychogenic understandings of NES are stigmatising and restrict professional displays of respectful (patient-centred) care. Those with the condition depict being negatively stereotyped, illegitimated and held morally culpable by health professionals. Perceived to lack medical, moral and credible status, participants describe practitioners who treat them with disrespect, and some recount conduct that defies all ethical and professional obligations and standards. These encounters can have wide-ranging adverse consequences for patients: emotionally, physically, and for their future healthcare. The quality of healthcare

From the results of the title study it appears that households in the Netherlands consumed 120 million m 3 natural gas more in 1995 than in 1994. The averaged consumption, however, was a little bit lower in 1995 than in 1994. The consumption of natural gas for cooking purposes and for water heating was the same. The small decrease of the average consumption was caused by space heating. BAK is an annual survey among circa 3,300 households in the Netherlands. Next to data on consumption, also appliances are inventorized as well as consumption patterns and behavioral aspects. 3 figs., 4 tabs

Full Text Available The essay examines the preoccupation with information technologies as a dominant theme of German poetry in the 1980s and 1990s. Outlining the historical shift from a critique of mass media to the ironic affirmation of hi-tech media, the investigation seeks an understanding of its driving forces. The analysis of Enzensberger's polemical essays on the culture industry shows the parallels and the difference in attitude between him and younger poets of the 1980s. A concise account of their publications illuminates the development of an aesthetically demanding poetry that kept aloof from the mass media. In their rejection of a common quotidian or sentimental tone, poets such as Thomas Kling and Durs Grunbein created new idioms and challenging forms while concentrating on hi-tech media as an epochal phenomenon. The sober reflection and technical terminology originate in a materialistic attitude, driven by the desire to regain the power of sophisticated aesthetic expression and to compensate for the loss of experience caused by the simulation of the past.The essay closes with a critical interpretation of the "mediamania" of the 1990s by giving heed to the fashionable remixing of poetic idioms that leaves the false impression of a new school of media poets.

We present extensive numerical simulations of Bak-Tang-Wiesenfeld (BTW) sandpile model on the hypercubic lattice in the upper critical dimension Du=4 . After re-extracting the critical exponents of avalanches, we concentrate on the three- and two-dimensional (2D) cross sections seeking for the induced criticality which are reflected in the geometrical and local exponents. Various features of finite-size scaling (FSS) theory have been tested and confirmed for all dimensions. The hyperscaling relations between the exponents of the distribution functions and the fractal dimensions are shown to be valid for all dimensions. We found that the exponent of the distribution function of avalanche mass is the same for the d -dimensional cross sections and the d -dimensional BTW model for d =2 and 3. The geometrical quantities, however, have completely different behaviors with respect to the same-dimensional BTW model. By analyzing the FSS theory for the geometrical exponents of the two-dimensional cross sections, we propose that the 2D induced models have degrees of similarity with the Gaussian free field (GFF). Although some local exponents are slightly different, this similarity is excellent for the fractal dimensions. The most important one showing this feature is the fractal dimension of loops df, which is found to be 1.50 ±0.02 ≈3/2 =dfGFF .

Full Text Available Ginsenoside Rh2 (G-Rh2 has been shown to induce apoptotic cell death in a variety of cancer cells. However, the details of the signal transduction cascade involved in G-Rh2-induced cell death is unclear. In this manuscript we elucidate the molecular mechanism of G-Rh2-induced apoptosis in human hepatoma SK-HEP-1 cells by demonstrating that G-Rh2 causes rapid and dramatic translocation of both Bak and Bax, which subsequently triggers mitochondrial cytochrome c release and consequent caspase activation. Interestingly, siRNA-based gene inactivation of caspase-8 effectively delays caspase-9 activation and apoptosis induced by G-Rh2, indicating that caspase-8 also plays an important role in the G-Rh2-induced apoptosis program. Taken together, our results indicate that G-Rh2 employs a multi pro-apoptotic pathway to execute cancer cell death, suggesting a potential role for G-Rh2 as a powerful chemotherapeutic agent.

Full Text Available The following discussion offers a panorama of the hermeneutical horizon from which the philological annotation apparatus of the Libro de los ritos critical edition was created. The book, written by the Dominican friar Diego Durán in 1579, describes the religious life of the Nahua people with emphasis in the Mexicas or Aztecs of the postclassical period. Also, this work offers some considerations about the ethnohistorical value of the Libro de los ritos and explains how this idea was used as a hypothesis to create the philological annotation apparatus of the critical edition. The value of the analysis of this experience is the contribution that it offers to the discussion between philologists about the proper methodology that must be used for the critical annotation of the Indian chronicles, documents that conserve the memory of the Native American people.

We define an activity-dependent branching ratio that allows comparison of different time series Xt . The branching ratio bx is defined as bx=E[ξx/x] . The random variable ξx is the value of the next signal given that the previous one is equal to x , so ξx={Xt+1∣Xt=x} . If bx>1 , the process is on average supercritical when the signal is equal to x , while if bxmarket hypothesis.” For stock volumes, solar x-ray flux intensities, and the Bak-Tang-Wiesenfeld (BTW) sandpile model, bx is supercritical for small values of activity and subcritical for the largest ones, indicating a tendency to return to a typical value. For stock volumes this tendency has an approximate power-law behavior. For solar x-ray flux and the BTW model, there is a broad regime of activity where bx≃1 , which we interpret as an indicator of critical behavior. This is true despite different underlying probability distributions for Xt and for ξx . For the BTW model the distribution of ξx is Gaussian, for x sufficiently larger than 1, and its variance grows linearly with x . Hence, the activity in the BTW model obeys a central limit theorem when sampling over past histories. The broad region of activity where bx is close to one disappears once bulk dissipation is introduced in the BTW model—supporting our hypothesis that it is an indicator of criticality.

small scaled buildings,they don't raise anything new, they are both important in order toclosely trail the architectural line of the period. Bakü’de bugün İçeri Şeher adıyla anılan eski Bakü yerleşiminde küçük ölçeklerde inşa edilmiş çok sayıda mescit bulunmaktadır. Bu makalede Selçuklular’ın Anadolu dışında Azerbaycan Bakü’de bıraktığı maddi kültür izlerinden en erken tarihli iki örnek ele alınmıştır. Çalışmada Türk dünyasında az bilinen bu iki eserin tarih, bani, plân, mimari ve bezeme gibi yönleriyle ayrıntılı biçimde ele alınması amaç edinilmiştir. Bu sebeple Bakü ve çevresindeki yapılarda: gerekli ölçümler, teknik çizimler ve fotoğraflama işlemleri yapılmıştır. Bunun ardından Bakü Berpa Arşivi’nde, Ahundov Kütüphanesi’nde ve Türkiye kütüphanelerinde kaynak araştırmaları ile çalışma tamamlanmıştır1. Türkler Anadolu’yu iskân edinmeleri ile başlattıkları süreçte elde ettikleri siyasi/askeri başarılarının yanında; belleklerinde getirdikleri estetik hissi, mimari anlayışı ve sanat biçimlerini de yeni yurtlarında uygulamışlardır. Bu hareketlilik boyunca geçtikleri güzergahlarda meydana getirdikleri kentlerde bıraktıkları izlerden, Anadolu öncesindeki kültürel mirasın örneklerini bulmak mümkündür.Her iki yapının da Selçuklular’dan günümüze ulaşabilmiş en erken tarihli iki eser olması Türk mimarisindeki gelişimin izlenmesi bakımından önemlidir. Selçuklular’ın Bakü’ye gelmesinden sonra inşa edilen ilk yapı olan Sınıg Gala Mescidi statik problemleri olan, sert kaba görüntülü ve yapıdan bağımsız büyük minaresiyle dikkat çekmektedir. Aşur Mescidi ise, çift katlı cephe düzenlemesi ve harimi bölen bezemeli destek kemeriyle az daha gelişmiş mimari arayışın bir ürünüdür. Ancak her iki kübik yapıda göze çarpan kusur; ağır, basık/karanlık başarısız bir mekan uygulamasıdır. Sonuç olarak, k

We define an activity-dependent branching ratio that allows comparison of different time series X(t). The branching ratio b(x) is defined as b(x)=E[xi(x)/x]. The random variable xi(x) is the value of the next signal given that the previous one is equal to x, so xi(x)=[X(t+1) | X(t)=x]. If b(x)>1, the process is on average supercritical when the signal is equal to x, while if b(x)efficient market hypothesis." For stock volumes, solar x-ray flux intensities, and the Bak-Tang-Wiesenfeld (BTW) sandpile model, b(x) is supercritical for small values of activity and subcritical for the largest ones, indicating a tendency to return to a typical value. For stock volumes this tendency has an approximate power-law behavior. For solar x-ray flux and the BTW model, there is a broad regime of activity where b(x) approximately equal 1, which we interpret as an indicator of critical behavior. This is true despite different underlying probability distributions for X(t) and for xi(x). For the BTW model the distribution of xi(x) is Gaussian, for x sufficiently larger than 1, and its variance grows linearly with x. Hence, the activity in the BTW model obeys a central limit theorem when sampling over past histories. The broad region of activity where b(x) is close to one disappears once bulk dissipation is introduced in the BTW model-supporting our hypothesis that it is an indicator of criticality.

Combined knowledge of the pelagic larval duration of coral species and coral recruitment patterns can provide evidence of inter-reef connectivity and indicate a reef’s ability to recover. We attempted to determine the maximum pelagic larval duration of Acropora humilis. Larvae were reared in a controlled environment unfavorable for settlement. The larvae lived in a pelagic state for a maximum of 29 days, although this is probably an underestimate of actual longevity for this species. Given the information available from the literature with respect to larval dispersal rates, it is not expected that larvae with this longevity will disperse further than 10-20 km from their natal reef, if at all. A long-term recruitment monitoring project was also set up on Abu Shosha Reef, which suffered nearly complete coral loss due to a bleaching event in summer of 2010. In April 2011, 60 settlement plates were placed on the reef. In July, a total of 102 living scleractinian recruits were counted on the plates. While pocilloporids were the most dominant recruits on the reef (57.8%), about 20.6% of living recruits belonged to Acroporidae, a family whose live cover on the reef is extremely low (0.67%). However, the overall mean density of recruits was very low (1.7 living recruits/100cm2) compared to similar studies around the world despite the spawning season having just ended. Fish surveys showed herbivore biomass to be very low compared to other reef systems in the world, but densities were significantly higher than another reef in the Red Sea with about 10 times more live coral cover. Recovery from bleaching for Abu Shosha and similar reefs in the region may be very slow relative to rates observed in other parts of the world if recruitment rates and herbivore communities remain low.

Testicular cancer is the most common form of solid cancer in young men. Testicular cancer is represented by testicular germ cell tumors (TGCTs) derived from embryonic stem cells with different degrees of differentiation in about 95% of cases. The development of these tumors is related to the formation of a pool of male germ cells and gametogenesis. Clinical factors that are predisposed to the development of germ-cell tumors include cryptorchidism and testicular microlithiasis, as well as infertility associated with the gr/gr deletion within the AZFс locus. KITLG, SPRY4, and BAK1 genes affect the development of the testes and gametogenesis; mutations and polymorphisms of these genes lead to a significant increase in the risk of the TGCT development. To determine the relationship between gene polymorphisms and the development of TGCTs, we developed a system for detection and studied the allele and genotype frequencies of the KITLG (rs995030, rs1508595), SPRY4 (rs4624820, rs6897876), and BAK1 (rs210138) genes in fertile men, patients with TGCTs, and patients with infertility that have the AZFс deletion. A significant association of rs995030 of the KITLG gene with the development of TGCTs (p = 0.029 for the allele G, p = 0.0124 for the genotype GG) was revealed. Significant differences in the frequencies of the studied polymorphisms in patients with the AZFc deletion and the control group of fertile men were not found. We showed significant differences in the frequencies for the combination of all high-risk polymorphisms in the control group, patients with the AZFc deletion and patients with TGCTs (p (TGCTs-AZF-control) = 0.0207). A fivefold increase in the frequency of the combination of all genotypes in the TGCT group (p = 0.0116; OR = 5.25 [1.44-19.15]) and 3.7-fold increase was identified in patients with the AZFc deletion (p = 0.045; OR = 3.69 [1.11-12.29]) were revealed. The genotyping of patients with infertility caused by the AZFc deletion can be used to

Local toxicity of benzalkonium chloride in ophthalmic solutions following repeated applications.
Okahara, Akihiko; Kawazu, Kouichi
2013-01-01
We performed repeated toxicity studies of benzalkonium chloride (BAK)-containing vehicles of ophthalmic solutions in monkeys and rabbits to assess the local toxicity of BAK after repeated applications on the ocular surface. Local toxicity of BAK was evaluated by toxicity studies in which a 0.01% BAK-containing vehicle was applied twice/day for 52 weeks, 4 times/day for 39 weeks, or 6 times/day for 13 weeks, or in which a 0.005% BAK-containing vehicle was applied 6 times/day for 52 weeks or twice/day for 4 weeks in monkeys. Local toxicity of BAK was also evaluated where a 0.01% BAK-containing vehicle was applied 6 times/day for 6 weeks, or a 0.005% BAK-containing vehicle was applied twice/day for 39 weeks or 8 times/day for 4 weeks in rabbits. These doses were chosen because BAK is generally used at concentrations up to 0.01% in ophthalmic solutions. The BAK-containing vehicle did not cause ophthalmological changes suggestive of irritation, allergy, or corneal damage. We also did not observe any histopathological changes in the eyeball, eyelid, lacrimal gland, and nasal cavity, with repeated applications of BAK for up to 52 weeks, up to 8 times/day, or at concentrations up to 0.01%, in monkeys and rabbits. Our results suggest that BAK in concentrations up to 0.01% in ophthalmic solution is non-toxic to the eyeball, its accessory organs, and the nasal cavity after long repeated applications.

Full Text Available Oestrogenic effects of macerated aqueous extracts of the leaves of Holarrhena fl oribunda (G. Don Dur & Schinz on ovariectomized rat. Estrogenic effects of aqueous extracts of leaves of Holarrhena fl oribunda have been evaluated by uterotrophic assay. Ovariectomized mice were used and treated subcutaneously during seven days with 50, 100, 200 mg.kg-1 doses of Holarrhena fl oribunda and with 100, 200 mg.kg-1 doses of Holarrhena fl oribunda plus 25 mg.kg-1 of oestradiol 17-β. Estrogenic activity was analysed by uterine dry and wet weight, surrenal gland wet weight, vaginal opening, protein and cholesterol level in uteri horn. Administration of extracts to the doses of 100 and 200 mg.kg-1 exhibits increase of uterine dry and wet weight, surrenal gland wet weight, vaginal opening, protein levels and decrease of level of cholesterol in uterine horn. The results suggest that, aqueous extracts of Holarrhena fl oribunda possesses estrogenic type effect. But when 100 and 200 mg.kg-1 of Holarrhena fl oribunda were given alone with 25 mg.kg-1 of estradiol 17-β, the estrogenic effect was slight. These results supposed that H. fl oribunda is a weak phytoestrogen and the aqueous extracts of the leaves behad as partial agonistic

We evaluated the in vitro cytotoxicity of benzalkonium chloride (BAK)-containing antiglaucoma eyedrops. We prepared cell cultures of SIRC, BCE C/D-1b, RC-1, and Chang conjunctiva. The viability of cell cultures was determined using the MTT and neutral red assays. The cell viability score (CVS) was used to compare the toxicity of test solutions. %CVS50 and %CVS40/80 of each eyedrop solution were 71 and 26 for Lumigan(®) (0.002% bimatoprost with 0.005% BAK), 100 and 99 for Tapros(®) (0.0015% tafluprost, a new formula from 2010 with 0.001% BAK), 39 and -29 for 2% Trusopt(®) (2% dorzolamide with 0.0075% BAK), 28 and -43 for Xalacom(®) (latanoprost/0.5% timolol with 0.02% BAK), 88 and 66 for DuoTrav(®) (travoprost/0.5% timolol with no BAK), 36 and -35 for Cosopt(®) (2% dorzolamide/0.5% timolol with 0.0075% BAK) and 53 and -1 for Combigan(®) (0.15% brimonidin/0.5% timolol with 0.005% BAK). Only Xalacom(®) and Tapros(®) did not show an apparent decrease in %CVS as compared to the corresponding concentration of BAK. In conclusion, the cytotoxicity of tested eyedrops was dependent on BAK. Only the eyedrops containing latanoprost or tafluprost showed a reduction in the cytotoxicity of BAK.

We investigated the potential short and long-term effects in cultured human trabecular meshwork (TM) cells of various topical glaucoma formulations containing different preservatives. We tested the fixed combination medications 0.004% travoprost plus 0.5% timolol preserved with either 0.015% benzalkonium chloride (BAK; DuoTrav®), or with 0.001% polyquad (PQ; DuoTrav(®) BAK-free); and 0.005% latanoprost plus 0.5% timolol preserved with 0.020% BAK (Xalacom(®)). Also tested was a range of BAK concentrations (0.001%-0.020%) in balanced salt solution (BSS). Cells were treated for 25 min at 37 °C with solutions diluted 1:10 and 1:100 to mimic the reduced penetration of topical preparations to the anterior chamber. The percentage of live cells was determined immediately after treatment through the uptake of the fluorescent vital dye calcein-AM. To determine any long-term effects, we assayed release of matrix metalloproteinase 9 (MMP-9) and apoptosis 24 h after treatments. BAK demonstrated a dose-dependent reduction in TM cell viability, ranging from 71±5% live cells at 0.001% BAK (diluted 1:10) to 33±3% live cells at 0.020% BAK (diluted 1:10). Travoprost (0.004%) plus 0.5% timolol preserved with 0.015% BAK had statistically fewer live TM cells (79±7%) than the same preparation preserved with 0.001% polyquad® (PQ; 93±1%; p<0.001). Latanoprost plus timolol preserved with 0.020% BAK (29±9% live cells) was similar to the 0.020% BAK (33±3%) treatment. However, travoprost plus timolol preserved in 0.015% BAK had significantly more live cells (83±12%) than the 1:10 dilution of 0.015% BAK (49±10%). We also found 0.020% BAK (diluted 1:100) resulted in elevated levels of extracellular MMP-9 at 24 h. These results demonstrate that the substitution of the preservative BAK from topical ophthalmic drugs results in greater in vitro viability of TM cells. Travoprost with timolol, but not latanoprost with timolol, countered some of the toxic BAK effects. BAK treatment

Full Text Available The Perspective of Muslim Consumers on Extravagance: A Cross-Cultural Comparative Study in Turkey, Qatar and Indonesia Abstract Islam encourages people to earn halal -or lawful- and sets certain rules on spending. In Quran spending in the way of Allah is praised (57:7 and besides this, eating, drinking and spending extravagantly is forbidden (6:141; 4:6; 7:31; 17:29. In Quran the term “extravagance” refers to various meanings (10:12; 3:146-147; 10:83; 5:32; 7:80-81; 7:31; 17:29. In daily life it means excessive or unnecessary expenditure or outlay of resources. In this regard the viewpoint of Muslim individuals on such phenomena which is forbidden in Quran becomes more crucial.

Full Text Available Abstract Background Drug utilization review (DUR programs are being conducted in Canadian hospitals with the aim of improving the appropriateness of prescriptions. However, there is little evidence of their effectiveness. The objective of this study was to assess the impact of both a retrospective and a concurrent DUR programs on the quality of in-hospital prescribing. Methods We conducted an interrupted time series quasi-experimental study. Using explicit criteria for quality of prescribing, the natural history of cisapride prescription was established retrospectively in three university-affiliated hospitals. A retrospective DUR was implemented in one of the hospitals, a concurrent DUR in another, whereas the third hospital served as a control. An archivist abstracted records of all patients who were prescribed cisapride during the observation period. The effect of DURs relative to the control hospital was determined by comparing estimated regression coefficients from the time series models and by testing the statistical significance using a 2-tailed Student's t test. Results The concurrent DUR program significantly improved the appropriateness of prescriptions for the indication for use whereas the retrospective DUR brought about no significant effect on the quality of prescribing. Conclusion Results suggest a retrospective DUR approach may not be sufficient to improve the quality of prescribing. However, a concurrent DUR strategy, with direct feedback to prescribers seems effective and should be tested in other settings with other drugs.

Full Text Available Resumo Novas tendências em gestão da cadeia de suprimentos têm fomentado grandes discussões na área, incluindo os paradigmas de alinhamento dinâmico e de gestão sustentável de cadeias. O primeiro prega que se deve gerenciar dinamicamente diferentes tipologias de cadeias (e.g. totalmente flexíveis, ágeis, enxutas e de reabastecimento contínuo a fim de responder adequadamente a comportamentos específicos dos clientes. O segundo preconiza que o projeto e a gestão dessas cadeias devem considerar questões ambientais e sociais, em complementação aos aspectos econômicos. Recentemente, alguns autores têm combinado essas tendências em um novo modelo conceitual visando melhor gerenciar trade-offs de sustentabilidade quando do projeto de cadeias de suprimentos. O objetivo deste trabalho é testar algumas das hipóteses levantadas por tal modelo em cadeias ágeis. Por meio de simulações em uma multinacional de bens de consumo não duráveis, foi possível verificar que o modelo proposto possui coerência e potencial para ajudar as empresas a projetar cadeias ágeis e verdes.

Residual oxygen time model for oxygen partial pressure near 130 kPa (1.3 atm).
Shykoff, Barbara E
2015-01-01
A two-part residual oxygen time model predicts the probability of detectible pulmonary oxygen toxicity P(P[O2tox]) after dives with oxygen partial pressure (PO2) approximately 130 kPa, and provides a tool to plan dive series with selected risk of P[O2tox]. Data suggest that pulmonary oxygen injury at this PO2 is additive between dives. Recovery begins after a delay and continues during any following dive. A logistic relation expresses P(P[O2tox]) as a function of dive duration (T(dur)) [hours]: P(P[O2tox]) = 100/[1+exp (3.586-0.49 x T(dur))] This expression maps T(dur) to P(P[O2tox]) or, in the linear mid-portion of the curve, P(P[O2tox]) usefully to T(dur). For multiple dives or during recovery, it maps to an equivalent dive duration, T(eq). T(eq) was found after second dives of duration T(dur 2). Residual time from the first dive t(r) = T(eq) - T(dur2). With known t(r), t and T(dur) a recovery model was fitted. t(r) = T(dur) x exp [-k x((t-5)/T(dur)2], where t = t - 5 hours, k = 0.149 for resting, and 0.047 for exercising divers, and t represents time after surfacing. The fits were assessed for 1,352 man-dives. Standard deviations of the residuals were 8.5% and 18.3% probability for resting or exercise dives, respectively.

To compare efficacy (intraocular pressure (IOP) reduction) and safety of preservative-free latanoprost (T2345) to benzalkonium chloride (BAK)-preserved latanoprost (BPL; Xalatan) in ocular hypertension (OHT) or primary open angle glaucoma (POAG) patients. Prospective, international, multicentre, randomised, investigator-masked, parallel-group trial. After a wash-out period, POAG or OHT patients, previously managed by BPL monotherapy, randomly received T2345 or BPL (one drop into the affected eye(s)) once daily from D0 to D84. Change in IOP was measured at 09:00 (±1 h) from D0 to D84 in the worse eye. Mean IOP reduction (D0-D84) was -8.6±2.6 mm Hg (-36%) on T2345 and -9.0±2.4 mm Hg (-38%) on BPL, confirming non-inferiority of T2345 to BPL. Non-inferiority of T2345 was observed from D15. The most frequent ocular adverse event, drug intolerance, was reported in 1 (0.5%) patient on T2345 versus 4 (2.1%) patients on BPL. Moderate to severe conjunctival hyperaemia was less frequent on T2345 than on BPL at D42 (20.2% vs 30.6%; p=0.003) and D84 (21.4% vs 29.1%; p=0.02). Upon instillation, the global subjective ocular symptom score was significantly lower on T2345 than BPL on D42 (0.15 vs 0.41; p=0.001) and D84 (0.18 vs 0.46; p=0.001). Preservative-free latanoprost has the same efficacy as BPL, with improved local tolerance.

Benzalkonium chloride (BAK), included as a preservative in many topical treatments for glaucoma, induces significant toxicity and alters tear breakup time (TBUT). BAK-containing latanoprost, an ester prodrug of prostaglandin F2α, can cause ocular adverse events (AEs) associated with BAK. The purpose of this study was to evaluate the efficacy and safety of BAK-free latanoprost. A prospective, open-label, single-arm, multicenter, 8-week study in patients with primary open-angle glaucoma or ocular hypertension taking BAK-containing latanoprost for ≥12 months was performed. Patients were switched to BAK-free latanoprost ophthalmic solution 0.005% administered once daily, and eyes were assessed after 28 and 56 days. Primary efficacy and safety variables were TBUT and treatment-emergent AEs, respectively. At day 56, 40 eyes were evaluable. Mean TBUT increased significantly from baseline (3.67±1.60 seconds) to 5.03±2.64 and 6.06±3.39 seconds after 28 and 56 days of treatment with BAK-free latanoprost (Preduction in conjunctival hyperemia and intraocular pressure was observed at both time points. No treatment-related serious AEs were evident and 12 (26.08%) treatment-emergent AEs occurred in seven patients, with eye pain and irritation being the most frequent. No clinically significant changes in vital signs or slit lamp examinations were observed. Results indicate that switching from BAK-containing latanoprost to BAK-free latanoprost resulted in significant improvements in TBUT, OSDI(©) score, and inferior corneal staining score, and measurable reductions in conjunctival hyperemia score. Furthermore, BAK-free latanoprost was well tolerated with only mild-to-moderate and self-limiting AEs. BAK-free latanoprost appears to be effective in protecting ocular surface integrity in glaucoma patients but further studies are needed to confirm this beneficial effect.

Benzalkonium chloride (BAK) is the most commonly used eye drop preservative. Benzalkonium chloride has been associated with toxic effects such as "dry eye" and trabecular meshwork degeneration, but the underlying biochemical mechanism of ocular toxicity by BAK is unclear. In this study, we propose a mechanistic basis for BAK's adverse effects. Mitochondrial O2 consumption rates of human corneal epithelial primary cells (HCEP), osteosarcoma cybrid cells carrying healthy (control) or Leber hereditary optic neuropathy (LHON) mutant mtDNA [11778(G>A)], were measured before and after acute treatment with BAK. Mitochondrial adenosine triphosphate (ATP) synthesis and cell viability were also measured in the BAK-treated control: LHON mutant and human-derived trabecular meshwork cells (HTM3). Benzalkonium chloride inhibited mitochondrial ATP (IC50, 5.3 μM) and O2 consumption (IC50, 10.9 μM) in a concentration-dependent manner, by directly targeting mitochondrial complex I. At its pharmaceutical concentrations (107-667 μM), BAK inhibited mitochondrial function >90%. In addition, BAK elicited concentration-dependent cytotoxicity to cybrid cells (IC50, 22.8 μM) and induced apoptosis in HTM3 cells at similar concentrations. Furthermore, we show that BAK directly inhibits mitochondrial O2 consumption in HCEP cells (IC50, 3.8 μM) at 50-fold lower concentrations than used in eye drops, and that cells bearing mitochondrial blindness (LHON) mutations are further sensitized to BAK's mitotoxic effect. Benzalkonium chloride inhibits mitochondria of human corneal epithelial cells and cells bearing LHON mutations at pharmacologically relevant concentrations, and we suggest this is the basis of BAK's ocular toxicity. Prescribing BAK-containing eye drops should be avoided in patients with mitochondrial deficiency, including LHON patients, LHON carriers, and possibly primary open-angle glaucoma patients.

Full Text Available The proposal of the present work is to approach the theme of humiliation, defined as moral degradation. It is about the intention of making someone feel inferior, of diminishing someone. It is therefore, a theme of moral interest. We divided this article into three big sections. On the first one, we shall mention some examples of humiliation and we shall emphasize the importance of studying this theme. On the second one, we shall deal with some theoretical concepts related to the pertaining theme, that is: the notion of respect, kinds of humiliation as to their form and content and, finally, the relationship of the concept of humiliation with that of shame and honor. On the third section, our objective was to present a review on the literature of researches made in Brazil related to the theme in question. Finally, the sequence which finalizes this work, deals with some characteristics which can be analyzed on studies about humiliation. In a preliminary but instigating way we make evident the need for new researches.

Seven isolates (DUR2, DUR4, DUR5, DUR8, DUR12, DUR18, and DUR20 out of 44 were able to produce EPS, and exhibited resistance to acid and bile salt compared to the reference strains Lactobacillus rhmnosus (ATCC53103 and L. plantarum (ATCC8014. The seven isolated strains belonged to five different species—L. plantarum, L. fermentum, L. crispatus, L. reuteri, and L. pentosus—which were identified using API 50 CHL and 16S rRNA gene sequences (Polymerase chain reaction, PCR – based. The seven strains displayed different ability to produce EPS (100–850 mg/L. Isolates exhibited a high survivability to acid (pH 3.0, bile salts (0.3%, and gastrointestinal tract model (<70%. Results showed that the auto-aggregation and cell surface hydrophobicity ranged from 39.98% to 60.09% and 50.80% to 80.53%, respectively, whereas, the highest co-aggregation value (66.44% was observed by L. fermentum (DUR8 with Pseudomonas aeruginosa. The isolates showed good inhibitory activity against tested pathogens, high antioxidant activity (32.29% to 73.36%, and good ability to reduce cholesterol (22.55% to 75.15%. Thus, the seven tested strains have value as probiotics.

We investigated the potential cytotoxicity of various topical ophthalmic glaucoma formulations containing different preservatives in cultured human trabecular meshwork (TM) and non-pigmented ciliary epithelial (NPCE) cell lines. We tested 0.004% travoprost preserved with either 0.015% benzalkonium chloride (BAK), sofZia or 0.001% Polyquad (PQ); and 0.005% latanoprost preserved with 0.020% BAK. We also tested a range of BAK concentrations in balanced salt solution (BSS). TM cells were treated for 10 min at 37°C with solutions diluted 1:10 to mimic the reduced penetration of topical preparations to the anterior chamber. Viability was determined by the uptake of the fluorescent vital dye calcein-AM (n = 6). BAK solutions (diluted 1:10) demonstrated a dose-dependent reduction in cell viability in both cell types (TM and NPCE). With a 1:10 dilution of 0.020% BAK, there were significantly more living NPCE cells (89 ± 6%) than TM cells (57 ± 6%; p < 0.001). In TM cells, travoprost + BAK had statistically fewer live cells (83 ± 5%) than both travoprost + sofZia (97 ± 5%) and travoprost + PQ (97 ± 6%; p < 0.05). Compared with BSS-treated NPCE cells, travoprost had statistically fewer live cells (p < 0.05) when preserved with BAK (85 ± 16%), sofZia (91 ± 6%) or PQ (94 ± 2%). These results demonstrate that substitution of BAK from topical ophthalmic drugs results in greater viability of cultured TM cells, the cells involved in the conventional outflow pathway. Cultured NPCE, responsible for aqueous inflow, appear more resilient to BAK.

This report is designed to dissect the detail molecular mechanism by which dihydroartemisinin (DHA), a derivative of artemisinin, induces apoptosis in human hepatocellular carcinoma (HCC) cells. DHA induced a loss of the mitochondrial transmemberane potential (ΔΨm), release of cytochrome c, activation of caspases, and externalization of phosphatidylserine indicative of apoptosis induction. Compared with the modest inhibitory effects of silencing Bax, silencing Bak largely prevented DHA-induced ΔΨm collapse and apoptosis though DHA induced a commensurable activation of Bax and Bak, demonstrating a key role of the Bak-mediated intrinsic apoptosis pathway. DHA did not induce Bid cleavage and translocation from cytoplasm to mitochondria and had little effects on the expressions of Puma and Noxa, but did increase Bim and Bak expressions and decrease Mcl-1 expression. Furthermore, the cytotoxicity of DHA was remarkably reduced by silencing Bim, and modestly but significantly reduced by silencing Puma or Noxa. Silencing Bim or Noxa preferentially reduced DHA-induced Bak activation, while silencing Puma preferentially reduced DHA-induced Bax activation, demonstrating that Bim and to a lesser extent Noxa act as upstream mediators to trigger the Bak-mediated intrinsic apoptosis pathway. In addition, silencing Mcl-1 enhanced DHA-induced Bak activation and apoptosis. Taken together, our data demonstrate a crucial role of Bim in preferentially regulating the Bak/Mcl-1 rheostat to mediate DHA-induced apoptosis in HCC cells.

The aim of this study was to determine and characterize the effect of topical application of benzalkonium chloride (BAK) on corneal nerves in vivo and in vitro. Thy1-YFP+ neurofluorescent mouse eyes were treated topically with vehicle or BAK (0.01% or 0.1%). Wide-field stereofluorescence microscopy was performed to sequentially image the treated corneas in vivo every week for 4 weeks, and changes in stromal nerve fiber density (NFD) and aqueous tear production were determined. Whole-mount immunofluorescence staining of corneas was performed with antibodies to axonopathy marker SMI-32. Western immunoblot analyses were performed on trigeminal ganglion and corneal lysates to determine abundance of proteins associated with neurotoxicity and regeneration. Compartmental culture of trigeminal ganglion neurons was performed in Campenot devices to determine whether BAK affects neurite outgrowth. BAK-treated corneas exhibited significantly reduced NFD and aqueous tear production, and increased inflammatory cell infiltration and fluorescein staining at 1 week (P reduction in neurites occurred after BAK addition to compartmental cultures of dissociated trigeminal ganglion cells. Although both BAK doses (0.0001% and 0.001%) reduced nerve fiber length, the reduction was significantly more with the higher dose (P < 0.001). Topical application of BAK to the eye causes corneal neurotoxicity, inflammation, and reduced aqueous tear production.

The purpose of this study is to compare the safety and intraocular pressure (IOP)-lowering efficacy of travoprost/timolol in a benzalkonium chloride (BAK)-free fixed combination preserved with polyquaternium-1 (TRA/TIM BAK-free), with travoprost/timolol-fixed combination preserved with BAK (TRA/TIM), in patients with open-angle glaucoma or ocular hypertension. In this prospective randomized controlled trial, subjects with IOP of at least 22 mm Hg in one or both eyes at 0900 h, and IOP of at least 21 mm Hg in one or both eyes at 1100 h and 1600 h at two eligibility visits were randomly assigned to receive either TRA/TIM BAK-free (n=195) or TRA/TIM (n=193), dosed once daily in the morning (0900 h) for 6 weeks. IOP was assessed at 0900 h, 1100 h, and 1600 h at each scheduled visit (baseline, 2 and 6 weeks after randomization). Mean IOP reduction across all visits and time points was 8.0 mm Hg in the TRA/TIM BAK-free group and 8.4 mm Hg in the TRA/TIM group (P=0.0943). The difference in mean IOP between groups ranged from 0.2 to 0.7 mm Hg across visits and time points, with a mean pooled difference of 0.4 mm Hg (95% CI: -0.1 to 0.8), demonstrating equivalence of the two formulations. The most common drug-related adverse event was hyperemia of the eye (ocular hyperemia and conjunctival hyperemia combined), occurring in 11.8% of the TRA/TIM BAK-free group and 13.0% of the TRA/TIM group. Travoprost/timolol BAK-free demonstrated equivalence to travoprost/timolol preserved with BAK in efficacy. No clinically relevant differences in the safety profiles of travoprost/timolol BAK-free and travoprost/timolol preserved with BAK were identified.

Long-term antiglaucomatous drug administration may cause irritation, dry eye, allergy, subconjunctival fibrosis, or increased risk of glaucoma surgery failure, potentially due to the preservative benzalkonium chloride (BAK), whose toxic, proinflammatory, and detergent effects have extensively been shown experimentally. We hypothesize that BAK also influences trabecular meshwork (TM) degeneration. Trabecular specimens were examined using immunohistology and reverse transcriptase-polymerase chain reaction. A trabecular cell line was stimulated by BAK and examined for apoptosis, oxidative stress, fractalkine and SDF-1 expression, and modulation of their receptors. An experimental model was developed with BAK subconjunctival injections to induce TM degeneration. Mass spectrometry (MS) imaging assessed BAK penetration after repeated instillations in rabbit eyes. Trabecular specimens showed extremely low densities of trabecular cells and presence of cells expressing fractalkine and fractalkine receptor and their respective mRNAs. Benzalkonium in vitro induced apoptosis, oxidative stress, and fractalkine expression and inhibited the protective chemokine SDF-1 and Bcl2, also inducing a sustained intraocular pressure (IOP) increase, with dramatic apoptosis of trabecular cells and reduction of aqueous outflow. MS imaging showed that BAK could access the TM at measurable levels after repeated instillations. BAK enhances all characteristics of TM degeneration typical of glaucoma-trabecular apoptosis, oxidative stress, induction of inflammatory chemokines-and causes degeneration in acute experimental conditions, potentially mimicking long-term accumulation. BAK was also shown to access the TM after repeated instillations. These findings support the hypothesis that antiglaucoma medications, through toxicity of their preservative, may cause further long-term trabecular degeneration and therefore enhance outflow resistance, reducing the impact of IOP-lowering agents.

The relationship between movement speed and duration during soccer matches

The relationship between the time duration of movement (t(dur)) and related maximum possible power output has been studied and modeled under many conditions. Inspired by the so-called power profiles known for discontinuous endurance sports like cycling, and the critical power concept of Monod and Scherrer, the aim of this study was to evaluate the numerical characteristics of the function between maximum horizontal movement velocity (HSpeed) and t(dur) in soccer. To evaluate this relationship, GPS data from 38 healthy soccer players and 82 game participations (≥30 min active playtime) were used to select maximum HSpeed for 21 distinct t(dur) values (between 0.3 s and 2,700 s) based on moving medians with an incremental t(dur) window-size. As a result, the relationship between HSpeed and Log(t(dur)) appeared reproducibly as a sigmoidal decay function, and could be fitted to a five-parameter equation with upper and lower asymptotes, and an inflection point, power and decrease rate. Thus, the first three parameters described individual characteristics if evaluated using mixed-model analysis. This study shows for the first time the general numerical relationship between t(dur) and HSpeed in soccer games. In contrast to former descriptions that have evaluated speed against power, HSpeed against t(dur) always yields a sigmoidal shape with a new upper asymptote. The evaluated curve fit potentially describes the maximum moving speed of individual players during the game, and allows for concise interpretations of the functional state of team sports athletes.

The study used a validated acute in vivo model to compare a new formulation of travoprost 0.004% ophthalmic solution(travoprost PQ), preserved with polyquaternium-1 (PQ), with commercially available formulations of benzalkonium-chloride(BAK)-preserved travoprost 0.004% ophthalmic solution(travoprost BAK) and BAK-preserved latanoprost 0.005%ophthalmic solution (latanoprost BAK). Adult male New Zealand albino rabbits (n = 36) were randomly divided into 6 groups. Phosphate-buffered saline (PBS), 0.001% PQ, 0.015% BAK, travoprost PQ, travoprost BAK or latanoprost BAK were applied onto rabbit eyes as 1 drop, for 15 times at 5-min intervals.The ocular surface reactions were investigated at hour 4 and day 1 using slitlamp examination; in vivo confocal microscopy (IVCM) for cornea, limbus and conjunctiva/conjunctiva-associated lymphoid tissue, conjunctival impression cytology and standard immunohistology in cryosections for detecting CD45+ infiltrating cells and MUC-5AC-labeled cells. PBS, PQ and travoprost PQ did not induce obvious irritation by clinical observation, changes in microstructures of the whole ocular surface as measured by IVCM analysis,inflammatory infiltration or cell damage as measured by impression cytology, altered levels of goblet cell counts or numerous CD45+ cells in the cornea. In contrast, all BAK-containing products induced diffuse conjunctival hyperemia and chemosis, abnormal changes in the ocular surface microstructure,significant total ocular surface toxicity scores,damaged epithelial cells, inflammatory cell infiltration and decreased goblet cell density. Travoprost PQ did not elicitocular surface toxicity when administered to rabbit eyes.These results suggest a greater safety advantage for the ocular surface of patients receiving chronic glaucoma treatment with PQ-preserved drugs.

Full Text Available The rearing method under controlled conditions known for Bombus terrestris was successful in initiating egg-laying for 83% of B. pascuorum queens. After larvae had hatched, fresh pollen pellets needed to be inserted into brood pockets daily. After the first workers had emerged, colony development was advanced by placing them outdoors and supplying them with a sugar solution and pollen. The bees were able to use tightly pressed pollen from small plastic pots inserted near the brood. This feeding resulted in large colonies that produced dozens of young queens. In contrast, colonies managed in the laboratory were unable to utilize pollen in a similar manner. They raised only a few workers and several queens. Mating young queens was easy. It was stimulated by daylight, but in the case of B. humilis by direct sunshine. Several B. pascuorum and B. sylvarum queens were overwintered and began the new generation under artificial conditions. However, a lack of fresh pollen limited the development of colonies outside of the vegetation period.

The irritative effects of preservatives found in ophthalmologic solution, or of antiseptics used for skin disinfection is a consistent problem for the patients. The reduction of the toxic effects of these compounds is desired. Brilliant Blue G (BBG) has shown to meet the expected effect in presence of benzalkonium chloride (BAK), a well known preservative in ophthalmic solutions, and octenidine dihydrochloride (Oct), used as antiseptic in skin and wound disinfection. BBG shows a significant protective effect on human corneal epithelial (HCE) cells against BAK and Oct toxicity, increasing the cell survival up to 51 % at the highest BAK or Oct concentration tested, which is 0.01 %, both at 30 min incubation. Although BBG is described as a P2x7 receptor antagonist, other selective P2x7 receptor antagonists, OxATP (adenosine 5'-triphosphate-2',3'-dialdehyde) and DPPH (N'-(3,5-dichloropyridin-4-yl)-3-phenylpropanehydrazide), did not reduce the cytotoxicity of neither BAK nor Oct. Therefore we assume that the protective effect of BBG is not due to its action on the P2x7 receptor. Brilliant Blue R (BBR), a dye similar to BBG, was also tested for protective effect on BAK and Oct toxicity. In presence of BAK no significant protective effect was observed. Instead, with Oct a comparable protective effect was seen with that of BBG. To assure that the bacteriostatic effect is not affected by the combinations of BAK/BBG, Oct/BBG and Oct/BBR, bacterial growth inhibition was analyzed on different Gram-negative and Gram-positive bacteria. All combinations of BAK or Oct with BBG hinder growth of Gram-positive bacteria. The combinations of 0.001 % Oct and BBR above 0.025 % do not hinder the growth of B. subtilis. For Gram-negative bacteria, BBG and BBR reduce, but do not abolish, the antimicrobial effect of BAK nor of Oct. In conclusion, the addition of BBG at bacterial inhibitory concentrations is suggested in the ready-to-use ophthalmic preparations and antiseptic solutions.

The Medicaid Drug Utilization Review (DUR) program is a 2-phase process conducted by Medicaid state agencies. The first phase is a prospective DUR and involves electronically monitoring prescription drug claims to identify prescription-related problems, such as therapeutic duplication, contraindications, incorrect dosage, or duration of treatment. The second phase is a retrospective DUR and involves ongoing and periodic examinations of claims data to identify patterns of fraud, abuse, underutilization, drug-drug interaction, or medically unnecessary care, implementing corrective actions when needed. The Centers for Medicare & Medicaid Services requires each state to measure prescription drug cost-savings generated from its DUR programs on an annual basis, but it provides no guidance or unified methodology for doing so. To describe and synthesize the methodologies used by states to measure cost-savings using their Medicaid retrospective DUR program in federal fiscal years 2014 and 2015. For each state, the cost-savings methodologies included in the Medicaid DUR 2014 and 2015 reports were downloaded from Medicaid's website. The reports were then reviewed and synthesized. Methods described by the states were classified according to research designs often described in evaluation textbooks. In 2014, the most often used prescription drugs cost-savings estimation methodology for the Medicaid retrospective DUR program was a simple pre-post intervention method, without a comparison group (ie, 12 states). In 2015, the most common methodology used was a pre-post intervention method, with a comparison group (ie, 14 states). Comparisons of savings attributed to the program among states are still unreliable, because of a lack of a common methodology available for measuring cost-savings. There is great variation among states in the methods used to measure prescription drug utilization cost-savings. This analysis suggests that there is still room for improvement in terms of

Despite the conflicting evidence, BAK is the most commonly used preservative in ophthalmic products largely due to its proven antimicrobial efficacy. This study was designed to characterize the antimi...

Full Text Available Bu derlemede omega-3 yağ asitlerinin insan sağlığına faydaları üzerinde durulmuştur. Beslenme canlıların büyümeleri, gelişmeleri ve yaşamlarını sürdürebilmeleri için gerekli olan gıdaları dış ortamdan alıp kullanmaları süreci olarak tanımlanırken; sağlıklı beslenme, besinlerin yeterli ve dengeli olarak alınması şeklinde tanımlanmaktadır. Son yıllarda yeterli ve dengeli beslenmenin önemi anlaşılmış ve beslenme alışkanlıkları değişmeye başlamıştır. Yağlar, insan organizması için gerekli olan en önemli unsurlardan bir tanesidir. Bunlar yüksek enerji kaynağı olmayıp aynı zamanda yağda çözünen vitaminleri bulundurmaları, proteinlerle birleşerek lipoproteinleri oluşturmaları ve kan lipit düzeylerinde rol oynamaları bakımından oldukça önemlidir. Doymuş yağ asitleri oda sıcaklığında katı halde bulundukları için vücutta birikebilirler. Çoklu doymamış yağ asitleri ise oda sıcaklığında sıvı haldedirler ve aynı zamanda insan hayatının devamlılığı için de çok önemlidirler. Bundan dolayı temel yağ asitleri olarak adlandırılarak omega- 6, omega-3 yağ asitleri olmak üzere iki gruba ayrılırlar, omega-6'ların ana kaynağı yüksek oranda linoleik asit içeren mısır ve soya fasülyesi yağıdır. Omega-3 ise keten tohumu, ceviz ve özellikle planktonlar ile yağlı balıklarda bol miktarda bulunur, keten tohumu ve cevizde alfa-linoleik asit, balık yağlarında ise eikosapentaenoik asit (EPA ve dekosahegzaenoik asit (DHA en önemli yağ asitleridir.

To investigate the effect of differently preserved ophthalmic solutions on the viability and barrier function of human corneal epithelial cells (HCEC) using fluorescent dyes. HCEC monolayers were exposed to the ophthalmic solutions containing benzalkonium chloride (BAK), edetate disodium, polyquad, stabilized oxychloro complex (Purite), sodium perborate, or sorbic acid for 5 min, 15 min, and 1 h. At 24 h after exposure, the cultures were assessed for metabolic activity using alamarBlue. The enzyme activity, membrane integrity, and apoptosis were evaluated using confocal microscopy. Barrier function was assessed using sodium fluorescein. The metabolic assay showed that the BAK-preserved ophthalmic solutions significantly reduced cell viability after a 5-min exposure compared to the phosphate buffered saline treated control (POphthalmic solutions with new preservatives had varying time-dependent adverse effects on cell viability, and the preservative-free solution had the least effect on HCEC. Sodium fluorescein permeability showed that HCEC monolayers treated with BAK-preserved solutions were more permeable to sodium fluorescein than those treated by the other ophthalmic solutions (Psolutions had greater adverse effects on metabolic activity, enzyme activity, membrane integrity, cell viability, and barrier function than the solutions that were not preserved with BAK. Our study suggests that BAK-free especially, preservative-free ophthalmic solutions are safer alternatives to BAK-preserved ones.

Few studies have evaluated the effectiveness of cyberbullying prevention/intervention programs. The goals of the present study were to develop a Theory of Reasoned Action (TRA)-based video program to increase cyberbullying knowledge (1) and empathy toward cyberbullying victims (2), reduce favorable attitudes toward cyberbullying (3), decrease positive injunctive (4) and descriptive norms about cyberbullying (5), and reduce cyberbullying intentions (6) and cyberbullying behavior (7). One hundred sixty-seven college students were randomly assigned to an online video cyberbullying prevention program or an assessment-only control group. Immediately following the program, attitudes and injunctive norms for all four types of cyberbullying behavior (i.e., unwanted contact, malice, deception, and public humiliation), descriptive norms for malice and public humiliation, empathy toward victims of malice and deception, and cyberbullying knowledge significantly improved in the experimental group. At one-month follow-up, malice and public humiliation behavior, favorable attitudes toward unwanted contact, deception, and public humiliation, and injunctive norms for public humiliation were significantly lower in the experimental than the control group. Cyberbullying knowledge was significantly higher in the experimental than the control group. These findings demonstrate a brief cyberbullying video is capable of improving, at one-month follow-up, cyberbullying knowledge, cyberbullying perpetration behavior, and TRA constructs known to predict cyberbullying perpetration. Considering the low cost and ease with which a video-based prevention/intervention program can be delivered, this type of approach should be considered to reduce cyberbullying. © 2015 Wiley Periodicals, Inc.

Impact of doctors' resistance on success of drug utilization review system.
Choi, Jong Soo; Yun, Seong Hyeon; Kim, Dongsoo; Park, Seung Woo
2014-04-01
The drug utilization review (DUR) system, which checks any conflict event of medications, contributes to improve patient safety. One of the important barriers in its adoption is doctors' resistance. This study aimed to analyze the impacts of doctors' resistance on the success of the DUR system. This study adopted an augmented the DeLone and McLean Information System (D&M IS) Success Model (2003), which used doctors' resistance as a socio-technological measure. This study framework is the same as that of the D&M IS Success Model in that it is based on qualities, such as system, information, and services. The major difference is that this study excluded the variable 'use' because it was not statistically significant for mandatory systems. A survey of doctors who used computers to enter prescriptions was conducted at a Korean tertiary hospital in February 2012. This study is very meaningful in that it is the first study to explore the success factors of the DUR system associated with doctors' resistance. Doctors' resistance to the DUR system was not statistically associated with user usefulness, whereas it affected user satisfaction. The results indicate that doctors still complain of discomfort in using the DUR system in the outpatient clinical setting, even though they admit that it contributes to patient safety. To mitigate doctors' resistance and raise user satisfaction, more opinions from doctors regarding the DUR system have to be considered and have to be reflected in the system.

Benzalkonium chloride (BAK), the most commonly used preservative in eye drops, is known to induce ocular irritation symptoms and dry eye in long-term treated patients and animal models. As tear film hyperosmolarity is diagnostic of some types of dry eye disease, we determined in vitro on conjunctival epithelial cells the cytoxicity of BAK in hyperosmolar conditions through cell viability, apoptosis, and oxidative stress assays. The Wong Kilbourne derivative of Chang conjunctival epithelial cells were cultured for 24 h or 48 h either in NaCl-induced hyperosmolar conditions (400-425-500 mOsM), in low concentrations of BAK (10(-4)%, 3.10(-4)%, and 5.10(-4)%), or in combination of both. We investigated cell viability through lysosomal integrity evaluation, cell death (cell membrane permeability and chromatin condensation), and oxidative stress (reactive oxygen species, superoxide anion) using spectrofluorimetry. Immunohistochemistry was performed for cytoskeleton shrinkage (phalloidin staining), mitochondrial permeability transition pore (cytochrome c release), the apoptosis effector active caspase-3, and the caspase-independent apoptosis factor AIF. We also observed early effects induced by the experimental conditions on the conjunctival cell layers using phase contrast imaging of live cells. As compared to standard culture solutions, hyperosmolar stress potentiated BAK cytotoxicity on conjunctival cells through the induction of oxidative stress; reduction of cell viability; cell membrane permeability increase; cell shrinkage with cell blebbing, as shown in phase contrast imaging of live cells; and chromatin condensation. Like BAK, but to a much lesser extent, hyperosmolarity increased cell death in a concentration-dependent manner through a caspase-dependent apoptosis characterized by a release of cytochrome c in the cytoplasm from mitochondria and the activation of caspase-3. Moreover, the caspase-independent apoptosis factor AIF was found translocated from

To evaluate and compare the toxicological profiles of two quaternary ammonium compounds (QAC), benzalkonium chloride (BAK), and cetalkonium chloride (CKC), in standard solution or cationic emulsion formulations in rabbit eyes using newly developed in vivo and ex vivo experimental approaches. Seventy eyes of 35 adult male New Zealand albino rabbits were used in this study. They were randomly divided into five groups: 50 microl of phosphate-buffered saline (PBS), PBS containing 0.02% BAK or 0.002% CKC (BAK Sol and CKC Sol, respectively), and emulsion containing 0.02% BAK or 0.002% CKC (BAK Em and CKC Em, respectively) were applied to rabbit eyes 15 times at 5-min intervals. The ocular surface changes induced by these eye drops were investigated using slit-lamp examination, flow cytometry (FCM), impression cytology (IC) on conjunctiva, and corneal in vivo confocal microscopy (IVCM). Standard immunohistology in cryosections was also examined for cluster of differentiation (CD) 45+ infiltrating and terminal deoxynucleotidyl transferase-mediated dUTP-nick end labeling (TUNEL)+ apoptotic cells. Clinical observations and IVCM showed that the highest toxicity was induced by BAK Sol, characterized by damaged corneal epithelium and a high level of inflammatory infiltration. BAK Em and CKC Sol presented moderate effects, and CKC Em showed the lowest toxicity with results similar to those of PBS. Conjunctival imprints analyzed by FCM showed a higher expression of RLA-DR and TNFR1 markers in BAK Sol-instilled eyes than in all other groups, especially at 4 h. Immunohistology was correlated with in vivo and ex vivo findings and confirmed this toxicity profile. A high level of infiltration of CD45+ inflammatory cells and TUNEL+ apoptotic cells was observed in limbus and conjunctiva, especially in QAC solution-receiving eyes compared to QAC emulsion-instilled eyes. The acute administration of 15 instillations at 5 min intervals was a rapid and efficient model to assess quaternary

To analyze the effect of preserved antiglaucoma eye drops on the expression of extracellular matrix (ECM) metalloproteinase inducer (EMMPRIN) in conjunctival epithelial cells. A total of 18 patients treated for primary open-angle glaucoma with benzalkonium chloride (BAK) preserved eye drops and eight age-matched controls were included in this study. Glaucoma patients were divided into two groups according to their daily exposure to BAK: high-exposure (HE) group and low-exposure (LE) group. HLA-DR and EMMPRIN were quantified on conjunctival impression cytology specimens using flow cytometry. In parallel, IOBA-NHC conjunctival epithelial cells were exposed to different BAK concentrations, in the presence or absence of cyclosporine A (CsA), and their total and surface expressions of EMMPRIN were assessed by flow cytometry and results are given in relative fluorescence intensities (RFIs). Compared to the control group (1.71 ± 0.39 RFI), EMMPRIN was significantly increased in the HE (4.19 ± 1.50 RFI, p EMMPRIN (R(2) = 0.875, p EMMPRIN, which was proportional to the concentration of BAK. The surface expression of EMMPRIN was inhibited by CsA. The increased expression of EMMPRIN in patients topically treated with multiple antiglaucoma BAK-preserved eye drops suggests a matrix metalloproteinase-related modification of conjunctival ECM remodeling. In vitro results suggest that CsA has the potential to limit BAK effects on EMMPRIN.

Cosmetic products, such as mascara, eye shadow, eyeliner and eye makeup remover are used extensively to highlight the eyes or clean the eyelids, and typically contain preservatives to prevent microbial growth. These preservatives include benzalkonium chloride (BAK) and formaldehyde (FA)-releasing preservatives. We hypothesize that these preservatives, at concentrations (BAK = 1 mg/ml; FA = 0.74 mg/ml) approved for consumer use, are toxic to human ocular surface and adnexal cells. Accordingly, we tested the influence of BAK and FA on the morphology, survival, and proliferation and signaling ability of immortalized human meibomian gland (iHMGECs), corneal (iHCECs) and conjunctival (iHConjECs) epithelial cells. iHMGECs, iHCECs and iHConjECs were cultured with different concentrations of BAK (5 μg/ml to 0.005 μg/ml) or FA (1 mg/ml to 1 μg/ml) under basal, proliferating or differentiating conditions up to 7 days. We used low BAK levels, because we found that 0.5 mg/ml and 50 μg/ml BAK killed iHMGECs within 1 day after a 15 min exposure. Experimental procedures included analyses of cell appearance, cell number, and neutral lipid content (LipidTox), lysosome accumulation (LysoTracker) and AKT signaling in all 3 cell types. Our results demonstrate that BAK and FA cause dose-dependent changes in the morphology, survival, proliferation and AKT signaling of iHMGECs, iHCECs and iHConjECs. Many of the concentrations tested induced cell atrophy, poor adherence, decreased proliferation and death, after 5 days of exposure. Cellular signaling, as indicated by AKT phosphorylation after 15 (FA) or 30 (BAK) minutes of treatment, was also reduced in a dose-dependent fashion in all 3 cell types, irrespective of whether cells had been cultured under proliferating or differentiating conditions. Our results support our hypothesis and demonstrate that the cosmetic preservatives, BAK and FA, exert many toxic effects on cells of the ocular surface and adnexa

Full Text Available The filamentous oomycete plant pathogen Phytophthora infestans causes late blight, an economically important disease, on members of the nightshade family (Solanaceae, such as the crop plants potato and tomato. The related plant Nicotiana benthamiana is a model system to study plant-pathogen interactions, and the susceptibility of N. benthamiana to Phytophthora species varies from susceptible to resistant. Little is known about the extent to which plant basal immunity, mediated by membrane receptors that recognise conserved pathogen-associated molecular patterns (PAMPs, contributes to P. infestans resistance.We found that different species of Phytophthora have varying degrees of virulence on N. benthamiana ranging from avirulence (incompatible interaction to moderate virulence through to full aggressiveness. The leucine-rich repeat receptor-like kinase (LRR-RLK BAK1/SERK3 is a major modulator of PAMP-triggered immunity (PTI in Arabidopsis thaliana and N. benthamiana. We cloned two NbSerk3 homologs, NbSerk3A and NbSerk3B, from N. benthamiana based on sequence similarity to the A. thaliana gene. N. benthamiana plants silenced for NbSerk3 showed markedly enhanced susceptibility to P. infestans infection but were not altered in resistance to Phytophthora mirabilis, a sister species of P. infestans that specializes on a different host plant. Furthermore, silencing of NbSerk3 reduced the cell death response triggered by the INF1, a secreted P. infestans protein with features of PAMPs.We demonstrated that N. benthamiana NbSERK3 significantly contributes to resistance to P. infestans and regulates the immune responses triggered by the P. infestans PAMP protein INF1. In the future, the identification of novel surface receptors that associate with NbSERK3A and/or NbSERK3B should lead to the identification of new receptors that mediate recognition of oomycete PAMPs, such as INF1.

Quaternary ammonium salts (QUATS), such as cetylpyridinium chloride (CPC) and benzalkonium chloride (BAK), are frequently used in antiseptic formulations, including toothpastes, mouthwashes, lozenges, throat and nasal sprays, and as biocides. Although in a recent ruling, the U.S. Food and Drug Administration (FDA) banned CPC from certain products and requested more data on BAK's efficacy and safety profile, QUATS, in general, and CPC and BAK, in particular, continue to be used in personal health care, food, and pharmaceutical and cleaning industries. We aimed to assess CPC's effects on mitochondrial toxicity and endocrine disruption in vitro . Mitochondrial O 2 consumption and adenosine triphosphate (ATP) synthesis rates of osteosarcoma cybrid cells were measured before and after CPC and BAK treatment. Antiestrogenic effects of the compounds were measured by a luciferase-based assay using recombinant human breast carcinoma cells (VM7Luc4E2, ERalpha-positive). CPC inhibited both mitochondrial O 2 consumption [half maximal inhibitory concentration (IC 50 ): 3.8μM] and ATP synthesis (IC 50 : 0.9μM), and additional findings supported inhibition of mitochondrial complex 1 as the underlying mechanism for these effects. In addition, CPC showed concentration-dependent antiestrogenic activity half maximal effective concentration [(EC 50 ): 4.5μM)]. BAK, another antimicrobial QUATS that is structurally similar to CPC, and the pesticide rotenone, a known complex 1 inhibitor, also showed mitochondrial inhibitory and antiestrogenic effects. In all three cases, there was overlap of the antiestrogenic activity with the mitochondrial inhibitory activity. Mitochondrial inhibition in vitro occurred at a CPC concentration that may be relevant to human exposures. The antiestrogenic activity of CPC, BAK, rotenone, and triclosan may be related to their mitochondrial inhibitory activity. Our findings support the need for additional research on the mitochondrial inhibitory and

Agp2 is a plasma membrane protein of the Saccharomyces cerevisiae amino acid transporter family, involved in high-affinity uptake of various substrates including L-carnitine and polyamines. The discovery of two high affinity polyamine permeases, Dur3 and Sam3, prompted us to investigate whether Agp2 directly transports polyamines or acts instead as a regulator. Herein, we show that neither dur3? nor sam3? single mutant is defective in polyamine transport, while the dur3? sam3? double mutant exhibits a sharp decrease in polyamine uptake and an increased resistance to polyamine toxicity similar to the agp2? mutant. Studies of Agp2 localization indicate that in the double mutant dur3? sam3?, Agp2-GFP remains plasma membrane-localized, even though transport of polyamines is strongly reduced. We further demonstrate that Agp2 controls the expression of several transporter genes including DUR3 and SAM3, the carnitine transporter HNM1 and several hexose, nucleoside and vitamin permease genes, in addition to SKY1 encoding a SR kinase that positively regulates low-affinity polyamine uptake. Furthermore, gene expression analysis clearly suggests that Agp2 is a strong positive regulator of additional biological processes. Collectively, our data suggest that Agp2 might respond to environmental cues and thus regulate the expression of several genes including those involved in polyamine transport. © 2013 Aouida et al.

About 70% of eyedrops contain benzalkonium chloride (BAK) as a preservative to prevent the growth of microorganisms. While preservatives are mandated to maintain sterility, many patients exhibit irritation and toxicity to such compounds. We propose to mitigate the ocular toxicity in the ocular formulations without compromising sterility by designing a device that can be incorporated into an eyedrops bottle to selectively remove the preservatives during the process of drop instillation. Here, we specifically focus on macroporous poly(2-hydroxyethyl methacrylate) (pHEMA) gel due to its excellent biocompatibility and high partition coefficient for BAK. In addition to specific selectivity for BAK, the device also requires high hydraulic permeability to allow drop dispensing without excessive pressure drop. The pHEMA monolith can remove nearly 100% of contained BAK from a 25 ml, 0.012% BAK solution with negligible uptake of the hydrophilic drugs such as timolol and dorzolamide. The filter, however, had to be pre-equilibrated with hydrophobic drugs to reach a high separation of BAK without reducing the concentration of the active drug. The average hydraulic permeability of the filter was 0.025 Darcy, which is about 5-fold lower than the ideal value. Incorporation of a pHEMA macroporous gel into an eyedrops bottle can virtually eliminate the exposure of the eyes to the preservatives without compromising the sterility. Our novel design can eliminate the preservative induced toxicity from eyedrops thereby impacting hundreds of millions of patients with chronic ophthalmic diseases such as glaucoma and dry eyes.

Ocular surface disease (OSD) is relatively common in glaucoma patients. OSD symptoms could be linked to prolonged exposure to preservatives in anti-glaucoma medications, especially benzalkonium chloride (BAK). The OBSERVE clinical audit was designed to track the impact of intraocular pressure lowering medications in patients with evidence of OSD to test the hypothesis that BAK-free anti-glaucoma preparations offer clinical advantages over BAK-containing products. Prospective clinical audit from March 2012 to April 2013, open to ophthalmologists practising in Australia. There were 375 patients enrolled, with a completion rate of 64%. The cohort was predominantly female (68%) with an average age of 71 years. Patients were screened for inclusion during a routine consultation. If eligible, they were enrolled. At the ophthalmologist's discretion, some patients were switched to BAK-free anti-glaucoma products. Data were collected via an online survey completed by the ophthalmologist during three appointments over a 16- to 30-week period for all patients. Intraocular pressure, tear-film breakup time, McMonnies Dry Eye Questionnaire score and reported lubricant use. Patients who switched to BAK-free preparations reported a significant fall in the use of lubricants (P = reduction in some OSD symptoms, but more research is needed. © 2014 Royal Australian and New Zealand College of Ophthalmologists.

What is dignity in prehospital emergency care?
Abelsson, Anna; Lindwall, Lillemor
2017-05-01
Ethics and dignity in prehospital emergency care are important due to vulnerability and suffering. Patients can lose control of their body and encounter unfamiliar faces in an emergency situation. To describe what specialist ambulance nurse students experienced as preserved and humiliated dignity in prehospital emergency care. The study had a qualitative approach. Data were collected by Flanagan's critical incident technique. The participants were 26 specialist ambulance nurse students who described two critical incidents of preserved and humiliated dignity, from prehospital emergency care. Data consist of 52 critical incidents and were analyzed with interpretive content analysis. Ethical considerations: The study followed the ethical principles in accordance with the Declaration of Helsinki. The result showed how human dignity in prehospital emergency care can be preserved by the ambulance nurse being there for the patient. The ambulance nurses meet the patient in the patient's world and make professional decisions. The ambulance nurse respects the patient's will and protects the patient's body from the gaze of others. Humiliated dignity was described through the ambulance nurse abandoning the patient and by healthcare professionals failing, disrespecting, and ignoring the patient. It is a unique situation when a nurse meets a patient face to face in a critical life or death moment. The discussion describes courage and the ethical vision to see another human. Dignity was preserved when the ambulance nurse showed respect and protected the patient in prehospital emergency care. The ambulance nurse students' ethical obligation results in the courage to see when a patient's dignity is in jeopardy of being humiliated. Humiliated dignity occurs when patients are ignored and left unprotected. This ethical dilemma affects the ambulance nurse students badly due to the fact that the morals and attitudes of ambulance nurses are reflected in their actions toward the patient.

To evaluate the role of nuclear factor-κB (NF-κB) activation in eye drop preservative toxicity and the effect of topical NF-κB inhibitors on preservative-facilitated allergic conjunctivitis. Balb/c mice were instilled ovalbumin (OVA) combined with benzalkonium chloride (BAK) and/or NF-κB inhibitors in both eyes. After immunization, T-cell responses and antigen-induced ocular inflammation were evaluated. Nuclear factor-κB activation and associated inflammatory changes also were assessed in murine eyes and in an epithelial cell line after BAK exposure. Benzalkonium chloride promoted allergic inflammation and leukocyte infiltration of the conjunctiva. Topical NF-κB inhibitors blocked the disruptive effect of BAK on conjunctival immunological tolerance and ameliorated subsequent ocular allergic reactions. In line with these findings, BAK induced NF-κB activation and the secretion of IL-6 and granulocyte-monocyte colony-stimulating factor in an epithelial cell line and in the conjunctiva of instilled mice. In addition, BAK favored major histocompatibility complex (MHC) II expression in cultured epithelial cells in an NF-κB-dependent fashion after interaction with T cells. Benzalkonium chloride triggers conjunctival epithelial NF-κB activation, which seems to mediate some of its immune side effects, such as proinflammatory cytokine release and increased MHC II expression. Breakdown of conjunctival tolerance by BAK favors allergic inflammation, and this effect can be prevented in mice by topical NF-κB inhibitors. These results suggest a new pharmacological target for preservative toxicity and highlight the importance of conjunctival tolerance in ocular surface homeostasis.

Full Text Available Abstract Background Although in vitro and in vivo laboratory studies have suggested that benzalkonium chloride (BAK in topical ophthalmic solutions may be detrimental to corneal epithelial cells, multiple short- and long-term clinical studies have provided evidence supporting the safety of BAK. Despite the conflicting evidence, BAK is the most commonly used preservative in ophthalmic products largely due to its proven antimicrobial efficacy. This study was designed to characterize the antimicrobial performance of two commonly used topical ocular hypotensive agents that employ different preservative systems: latanoprost 0.005% with 0.02% BAK and travoprost 0.004% with sofZia, a proprietary ionic buffer system. Methods Each product was tested for antimicrobial effectiveness by European Pharmacopoeia A (EP-A standards, the most stringent standards of the three major compendia, which specify two early sampling time points (6 and 24 hours not required by the United States Pharmacopeia or Japanese Pharmacopoeia. Aliquots were inoculated with between 105 and 106 colony-forming units of the test organisms: Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Candida albicans and Aspergillus brasiliensis. Sampling and enumeration were conducted at protocol-defined time points through 28 days. Results BAK-containing latanoprost met EP-A criteria by immediately reducing all bacterial challenge organisms to the test sensitivity and fungal challenges within the first six hours while the preservative activity of travoprost with sofZia did not. Complete bacterial reduction by travoprost with sofZia was not shown until seven days into the test, and fungal reduction never exceeded the requisite 2 logs during the 28-day test. Travoprost with sofZia also did not meet EP-B criteria due to its limited effectiveness against Staphylococcus aureus. Both products satisfied United States and Japanese pharmacopoeial criteria.

Full Text Available Arabidopsis, 7-transmembrane Regulator of G signaling protein 1 (AtRGS1 modulates canonical G protein signaling by promoting the inactive state of heterotrimeric G protein complex on the plasma membrane. It is known that plant leucine-rich repeat receptor-like kinases (LRR RLKs phosphorylate AtRGS1 in vitro but little is known about the in vivo interaction, molecular dynamics, or the cellular consequences of this interaction.Therefore, a subset of the known RLKs that phosphorylate AtRGS1 were selected for elucidation, namely, BAK1, BIR1, FLS2. Several microscopies for both static and dynamic protein-protein interactions were used to follow in vivo interactions between the RLKs and AtRGS1 after the presentation of the Pathogen-associated Molecular Pattern, Flagellin 22 (Flg22. These microscopies included Förster Resonance Energy Transfer, Bimolecular Fluoresence Complementation, and Cross Number and Brightness Fluorescence Correlation Spectroscopy. In addition, reactive oxygen species and calcium changes in living cells were quantitated using luminometry and R-GECO1 microscopy.The LRR RLKs BAK1 and BIR1, interact with AtRGS1 at the plasma membrane. The RLK ligand flg22 sets BAK1 in motion toward AtRGS1 and BIR1 away, both returning to the baseline orientations by 10 minutes. The C-terminal tail of AtRGS1 is important for the interaction with BAK1 and for the tempo of the AtRGS1/BIR1 dynamics. This window of time corresponds to the flg22-induced transient production of reactive oxygen species and calcium release which are both attenuated in the rgs1 and the bak1 null mutants.A temporal model of these interactions is proposed. flg22 binding induces nearly instantaneous dimerization between FLS2 and BAK1. Phosphorylated BAK1 interacts with and enables AtRGS1 to move away from BIR1 and AtRGS1 becomes phosphorylated leading to its endocytosis thus leading to de-repression by permitting AtGPA1 to exchange GDP for GTP. Finally, the G protein complex

Although in vitro and in vivo laboratory studies have suggested that benzalkonium chloride (BAK) in topical ophthalmic solutions may be detrimental to corneal epithelial cells, multiple short- and long-term clinical studies have provided evidence supporting the safety of BAK. Despite the conflicting evidence, BAK is the most commonly used preservative in ophthalmic products largely due to its proven antimicrobial efficacy. This study was designed to characterize the antimicrobial performance of two commonly used topical ocular hypotensive agents that employ different preservative systems: latanoprost 0.005% with 0.02% BAK and travoprost 0.004% with sofZia, a proprietary ionic buffer system. Each product was tested for antimicrobial effectiveness by European Pharmacopoeia A (EP-A) standards, the most stringent standards of the three major compendia, which specify two early sampling time points (6 and 24 hours) not required by the United States Pharmacopeia or Japanese Pharmacopoeia. Aliquots were inoculated with between 10(5) and 10(6) colony-forming units of the test organisms: Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Candida albicans and Aspergillus brasiliensis. Sampling and enumeration were conducted at protocol-defined time points through 28 days. BAK-containing latanoprost met EP-A criteria by immediately reducing all bacterial challenge organisms to the test sensitivity and fungal challenges within the first six hours while the preservative activity of travoprost with sofZia did not. Complete bacterial reduction by travoprost with sofZia was not shown until seven days into the test, and fungal reduction never exceeded the requisite 2 logs during the 28-day test. Travoprost with sofZia also did not meet EP-B criteria due to its limited effectiveness against Staphylococcus aureus. Both products satisfied United States and Japanese pharmacopoeial criteria. Latanoprost with 0.02% BAK exhibited more effective microbial protection than

The benzalkonium chloride (BAK) content of tafluprost ophthalmic solution (Tapros(®): tafluprost) has been reduced to balance corneal safety and preservative effectiveness (old formulation: 0.01%; new formulation: 0.001%). However, no reports have been published on its clinical effect. Therefore, we conducted a clinical research study to compare the safety of BAK-reduced tafluprost on the ocular surface with other prostaglandin ophthalmic solutions. This clinical study included 28 glaucoma patients (28 eyes) with a treatment history of latanoprost ophthalmic solution (Xalatan(®)) or travoprost ophthalmic solution (Travatan Z(®)), who presented with corneal epithelial disorders. The subjects were switched to BAK-reduced tafluprost, and its effect on the ocular surface was examined after 1 and 2 months of treatment [using fluorescein staining score, hyperemia, tear film breakup time, and intraocular pressure (IOP) lowering]. In all analyzed subjects (N=27), the fluorescein staining score was significantly improved after switching to BAK-reduced tafluprost (P<0.0001). Conversely, the IOP-lowering effect was not notably changed. The subjects switched from latanoprost (n=10) showed significant improvement in fluorescein staining score (P<0.05) as well as in IOP lowering (P<0.01). The subjects switched from travoprost (n=17) also showed significant improvement in fluorescein staining score (P<0.001), but without a significant change in IOP lowering. Tafluprost with reduced BAK has potential as a superior antiglaucoma drug, not only for its IOP-lowering effect, but also for its good corneal safety profile.

Full Text Available During the year 1692 there was a shortage of cereals and the became too expensive. On Sunday; June the eighth; the corn was finished and the functionaries responsible of the distribution beat the Indian women that protested. Very soon a lot of people congregated and started a riot. The viceroyal palace and the «cabildo» houses were burned and many shops plundered. The repression was very hard; specially against the Indian people; but the Indians weren’t the only ones involved. Blacks and mestee population were the «plebe»; the populace of the city; offended by the injustices of the government and the humiliations of the proud rich Spaniards. The Spanish population started feeling fear of their neighbors; not only Indians but poor people.
En 1692 hubo escasez y carestía de cereales en la ciudad de México. Un domingo del mes de junio se acabó el maíz en la alhóndiga y los encargados de repartirlo golpearon a las indias que protestaban. Muy pronto llegó mucha gente y se inició un alboroto que duró varias horas y durante el cual se incendiaron el palacio de los virreyes y las casas del cabildo; muchas tiendas fueron saqueadas. La represión fue muy dura y se dirigió contra los indios; pero no fueron sólo indios los que participaron en el motín, sino la «plebe» de la ciudad, mezcla de todos los grupos resentidos por las injusticias del gobierno y las humillaciones de los ricos españoles. La población española comenzó a sentir miedo de sus vecinos, que ya no se identificaban con los indios. -

We investigated in a rabbit model, the eye distribution of topically instilled benzalkonium_(BAK) chloride a commonly used preservative in eye drops using mass spectrometry imaging. Three groups of three New Zealand rabbits each were used: a control one without instillation, one receiving 0.01%BAK twice a day for 5 months and one with 0.2%BAK one drop a day for 1 month. After sacrifice, eyes were embedded and frozen in tragacanth gum. Serial cryosections were alternately deposited on glass slides for histological (hematoxylin-eosin staining) and immunohistological controls (CD45, RLA-DR and vimentin for inflammatory cell infiltration as well as vimentin for Müller glial cell activation) and ITO or stainless steel plates for MSI experiments using Matrix-assisted laser desorption ionization time-of-flight. The MSI results were confirmed by a round-robin study on several adjacent sections conducted in two different laboratories using different sample preparation methods, mass spectrometers and data analysis softwares. BAK was shown to penetrate healthy eyes even after a short duration and was not only detected on the ocular surface structures, but also in deeper tissues, especially in sensitive areas involved in glaucoma pathophysiology, such as the trabecular meshwork and the optic nerve areas, as confirmed by images with histological stainings. CD45-, RLA-DR- and vimentin-positive cells increased in treated eyes. Vimentin was found only in the inner layer of retina in normal eyes and increased in all retinal layers in treated eyes, confirming an activation response to a cell stress.

Studies of the resistance and accumulation ability of different plant species to uranium (U) has important influence on the bioremediation of U contaminated soil. The resistance and enrichment ability of high concentrations of U (500 mg · kg"-"1 soil) in fourteen plant species were investigated and evaluated in this study in order to screen remediation plants for governance soil U contamination. The results showed that: (1) high concentrations of U stress had different effects on the emergence and survival of the different plants. The seed emergence of Hibiscus esculentus was reduced by 2/3, but the seed emergence of Gynura cusimbua (D. Don) S. Moore, Chenopodium album L. and Phaseolus vulgaris var. humilis Alef were not reduced. Under the contaminated soil, all the sesamum indicum died within a month after the emergence and the survival number of Amaranth and Iresine herbstii 'Aureo-reticulata' reduced by about 80%. But the survival number of Alternanthera philoxeroides (Mart.) Griseb., Chenopodium album L. and Phaseolus vulgaris var. humilis Alef were not influenced. (2) The biomass of the plants would be reduced by 8-99% in the uranium-contaminated soil. The anti-stress ability of Phaseolus vulgaris var. humilis Alef was the strongest in the fourteen plants, and Cucurbita pepo L., Sorghumbicolor (L.) Moench, Ipomoea aquatica Forsk, Helianthus annuus, Chenopodium album L. and Alternanthera philoxeroides (Mart.) Griseb. showed some the anti-stress ability. (3) Significant differences were found in the capacity of plants to absorb uranium between under high-uranium contaminated soil and under the non-uranium contaminated soil were. The plants with higher uranium content in thenon-contaminated soil were Gomphrena globosa, and Cucurbita pepo L., which were 2.249 mg · kg"-"1 DW and 1.620 mg · kg"-"1 DW, respectively. But the plants with higher uranium content in the high uranium contaminated soil were Cichorium intybus L., Amaranth and Ipomoea aquatica Forsk, which

Full Text Available Peanut, Arachis hypogaea (Linnaeus, 1753 is an allotetraploid cultivated plant with two subgenomes derived from the hybridization between two diploid wild species, A. duranensis (Krapovickas & W. C. Gregory, 1994 and A. ipaensis (Krapovickas & W. C. Gregory, 1994, followed by spontaneous chromosomal duplication. To understand genome changes following polyploidy, the chromosomes of A. hypogaea, IpaDur1, an induced allotetraploid (A. ipaensis × A. duranensis4x and the diploid progenitor species were cytogenetically compared. The karyotypes of the allotetraploids share the number and general morphology of chromosomes; DAPI+ bands pattern and number of 5S rDNA loci. However, one 5S rDNA locus presents a heteromorphic FISH signal in both allotetraploids, relative to corresponding progenitor. Whilst for A. hypogaea the number of 45S rDNA loci was equivalent to the sum of those present in the diploid species, in IpaDur1, two loci have not been detected. Overall distribution of repetitive DNA sequences was similar in both allotetraploids, although A. hypogaea had additional CMA3+ bands and few slight differences in the LTR-retrotransposons distribution compared to IpaDur1. GISH showed that the chromosomes of both allotetraploids had preferential hybridization to their corresponding diploid genomes. Nevertheless, at least one pair of IpaDur1 chromosomes had a clear mosaic hybridization pattern indicating recombination between the subgenomes, clear evidence that the genome of IpaDur1 shows some instability comparing to the genome of A. hypogaea that shows no mosaic of subgenomes, although both allotetraploids derive from the same progenitor species. For some reasons, the chromosome structure of A. hypogaea is inherently more stable, or, it has been at least, partially stabilized through genetic changes and selection.

Comparison of interbody fusion approaches for disabling low back pain.
Hacker, R J
1997-03-15
This is a study comparing two groups of patients surgically treated for disabling low back pain. One group was treated with lumbar anteroposterior fusion (360 degrees fusion), the other with posterior lumbar interbody fusion and an interbody fixation device. To determine which approach provided the best and most cost-effective outcome using similar patient selection criteria. Others have shown that certain patients with disabling low back pain benefit from lumbar fusion. Although rarely reported, the costs of different surgical treatments appear to vary significantly, whereas the patient outcome may vary little. Since 1991, 75 patients have been treated Starting in 1993, posterior lumbar interbody fusion BAK was offered to patients as an alternative to 360 degrees fusion. The treating surgeon reviewed the cases. The interbody fixation device used (BAK; Spine-Tech, Inc., Minneapolis, MN) was part of a Food and Drug Administration study. Patient selection criteria included examination, response to conservative therapy, imaging, psychological profile, and discography. North American Spine Society outcome questionnaires, BAK investigation data radiographs, chart entries, billing records and patient interviews were the basis for assessment. Age, sex compensable injury history and history of previous surgery were similar. Operative time; blood loss, hospitalization time, and total costs were significantly different. There was a quicker return to work and closure of workers compensation claims for the posterior lumbar interbody fusion-BAK group. Patient satisfaction was comparable at last follow-up. Posterior lumbar interbody fusion-BAK achieves equal patient satisfaction but fiscally surpasses the 360 degrees fusion approach. Today's environment of regulated medical practice requires the surgeon to consider cost effectiveness when performing fusion for low back pain.

The purpose of this investigation was to determine the effect of a sodium hypochlorite-surfactant combination on the removal of Enterococcus faecalis from infected teeth. Sixty-four extracted human single canal anterior teeth were prepared with rotary instrumentation and sterilized. Teeth were divided into 4 groups, N = 16. Three experimental groups were inoculated with E. faecalis and cultured for 21 days before use: positive control group, no irrigation; NaOCl group, irrigated with 5 mL 6% NaOCl; and NaOCl/BAK group, irrigated with 5 mL 6% NaOCl/0.008% benzalkonium chloride (BAK). The negative control group received medium only and no inoculate. Paper point sampling of the canals was obtained before irrigation (S1) for all 4 groups and for 2 groups after irrigation (S2) to determine remaining colony-forming units. After sampling, all teeth were split in half and evaluated for bacterial viability colony-forming units and penetration of dentinal tubules by using fluorescent vital dye staining and confocal laser scanning microscopy. Comparison of pre-irrigation and post-irrigation paper point samples from the 2 irrigated groups showed a significant reduction in bacterial canal load (P < .001, Kruskal-Wallis), with a significantly lower load in the NaOCl/BAK group than in the NaOCl group (P = .001, Mann-Whitney U test); 68.8% of the NaOCl/BAK samples gave no recoverable counts. In contrast, no significant difference between these groups was found for counts recovered from dentin. Confocal laser scanning microscopy showed no differences in tubule penetration. The addition of BAK to NaOCl significantly reduced the number of remaining bacteria within the canal after irrigation compared with NaOCl alone. Published by Elsevier Inc.

The accumulation of protein-bound toxins in dialyzed patients is strongly associated with their high morbidity and mortality. The bioartificial kidney device (BAK), containing proximal tubule epithelial cells (PTEC) seeded on functionalized synthetic hollow fiber membranes (HFM), may be a powerful solution for the active removal of those metabolites. In an earlier study, we developed an upscaled BAK containing conditionally immortalized human PTEC (ciPTEC) with functional organic cationic transporter 2 (OCT2). Here, we first extended this development to a BAK device having cells with the organic anionic transporter 1 (OAT1), capable of removing anionic uremic wastes. We confirmed the quality of the ciPTEC monolayer by confocal microscopy and paracellular inulin-FITC leakage, as well as, by the active transport of anionic toxin, indoxyl sulfate (IS). Furthermore, we assessed the immune-safety of our system by measuring the production of relevant cytokines by the cells after lipopolysaccharide (LPS) stimulation. Upon LPS treatment, we observed a polarized secretion of pro-inflammatory cytokines by the cells: 10-fold higher in the extraluminal space, corresponding to the urine compartment, as compared to the intraluminal space, corresponding to the blood compartment. To the best of our knowledge, our work is the first to show this favorable cell polarization in a BAK upscaled device. This article is protected by copyright. All rights reserved.

Resident physicians in Mexico: tradition or humiliation
Directory of Open Access Journals (Sweden)
Donovan Casas Patiño
2013-08-01
Full Text Available Mexico has a great history and tradition in relation to the training of resident physicians, but what we find behind this process?, Power relations implied and not implied, unnoticed or ignored for convenience by the academic and health institutions, with the aggravation of forgetting its commitment to the training of men and women "professionals" and limited to meet another indicator of "human resources for health." The resident physician in academic and scientific training is immersed in this dehumanized maelstrom and ends up becoming a character for the domain of knowledge as power, forgetting that his act and its rationale lies in the principle of "primum non nocere" to that we would add: nor your person, nor your fellowman, much less whom you have the moral, ethical and civic responsibility to convey some of your knowledge and your experience, that is, part of your essence”.

Full Text Available Çalışmamızda ülkemizde üniversite gençliği ve mezunlarına yönelik olarak kadınlarda hangi oranlarda cinsel şiddet eylemlerinin gerçekleştiği, kimler tarafından, nerede, ne zaman uygulandığı, adli makamlara ne derece yansıdığı, yansımıyorsa nedenleri ve mağdurların etkilenme dereceleri araştırılmıştır. Araştırmamıza üniversite öğrencisi ve mezunu toplam 700 kadın katılmıştır. İddia ettiğimiz veriler literatürlerle uyumlu olarak kadınların bu eylemlere yüksek oranlarda maruz, kaldığını ve özellikle temas içeren cinsel şiddet türlerinin sanılanın aksine yabancılar tarafından değil, çoğunlukla tanıdık kişilerce gerçekleştirildiği, çok büyük oranının adli makamlara yansımadığını ortaya koymuştur. Sözel, görsel ve dokunsal cinsel şiddet türlerinden herhangi birine maruz kalma oranı kadınlarda % 84 tür. Basit cinsel içerikli dokunuştan zorla cinsel ilişkiye kadar uzanan dokunsal cinsel şiddet türlerine maruz kalma oranı ise % 44.8 olarak bulunmuştur. Mağduriyet oranının yüksekliğinin yanı sıra adli makamlara iletilme oranlarının düşük olması, özellikle adli tıp açısından olayı ispatlama zorluğunu aşacak çalışmaların (etkin muayene ve delillerin değerlendirilmesi önemini ortaya koymaktadır.

üzündeki varlığını, toplumsal bir mutabakat ile mümkün kılmıştır. Bu mutabakatın belli görüngüleri vardır ve bunlar daha çok kültürel formlarla karşımıza çıkar. Milletlerin toplumsal varlıklarını ortaya koymada karşımıza çıkan ilk verileri ve anlam yüklenmelerini destanlar temerküz eder. Bu bakımdan, destanlara milletlerin toplumsal hafızasının kodları olarak odaklanmak gerekir. İnsanoğlunun ilk atasından bu yana yeryüzünde ortaya koyduğu çabanın birtakım ana amaçlar ve temalar etrafında söz konusu olduğu bir gerçektir. Bu yüzden, barındırdığı arketipler bakımından destanların önemi büyüktür. Bu arketiplerin sadece geçmişi okumakla kalmayıp günümüze de ışık tutacak birtakım içermelere sahip olduğu bilinmektedir. Bu da, milletlerin ve toplumların kültürel görüngülerinin köklerine ulaşmak açısından bazı imkânlar oluşturmaktadır. Türk destanlarına bakıldığında, milletleşme yolunda önemli bir adım sayılacak Oğuz Kağan Destanı’nın bizleri karşıladığı görülür. Destanları anlamak ve anlamlandırmak için bazı farklı yöntemler söz konusu edilmektedir. Bu yöntemlerden birini, Tarihi-Coğrafi Fin Okulunun yöntemlerinden biri olan Axel Olrik’in “Epik Kanunlar Teorisi” oluşturmaktadır. Bu teori, mitolojik ürünlere evrensel bir standardizasyonla yaklaşmaya çalışmakta ve onları belli ilkeler çerçevesinde değerlendirmektedir. Bu makale, Türk tarihinin mitolojik uzantıları açısından sembolik olarak oldukça yüklü olan Oğuz Kağan Destanı’nı, Axel Olrik’in söz konusu epik yasaları ışığında okumayı amaçlamakta olup elde edilen bulguları, destan ve mahiyeti bağlamında tartışmaya çalışmaktadır.

Full Text Available Human lysosomal-associated protein multispanning membrane 5 (LAPTM5 was identified by an ordered differential display-polymerase chain reaction (ODD-PCR as an up-regulated cDNA fragment during 12-O-tetradecanoylphorbol 13-acetate (TPA-induced differentiation of U937 cells into monocytes/macrophages. After TPA-treatment, the levels of LAPTM5 mRNA and protein increased and reached a maximum at 18-36 h. In healthy human tissues, LAPTM5 mRNA was expressed at high levels in hematopoietic cells and tissues, at low levels in the lung and fetal liver, and was not detected in other non-hematopoietic tissues. LAPTM5 mRNA was detected in immature malignant cells of myeloid lineage, such as K562, HL-60, U937, and THP-1 cells, and in unstimulated peripheral T cells, but was absent or barely detectable in lymphoid malignant or non-hematopoietic malignant cells. The LAPTM5 level in HL-60 cells increased more significantly during TPA-induced monocyte/macrophage differentiation than during DMSO-induced granulocyte differentiation. Ectopic expression of GFP-LAPTM5 or LAPTM5 in HeLa cells exhibited the localization of LAPTM5 to the lysosome. In HeLa cells overexpressing LAPTM5, the Mcl-1 and Bid levels declined markedly and apoptosis was induced via Bak activation, Δψm loss, activation of caspase-9, -8 and -3, and PARP degradation without accompanying necrosis. However, these LAPTM5-induced apoptotic events except for the decline of Bid level were completely abrogated by concomitant overexpression of Mcl-1. The pan-caspase inhibitor (z-VAD-fmk could suppress the LAPTM5-induced apoptotic sub-G1 peak by ~40% but failed to block the induced Δψm loss, whereas the broad-range inhibitor of cathepsins (Cathepsin Inhibitor I could suppress the LAPTM5-induced apoptotic sub-G1 peak and Δψm loss, by ~22% and ~23%, respectively, suggesting that the LAPTM5-mediated Δψm loss was exerted at least in part in a cathepsin-dependent manner.

Dora Bruder and the Longue Durée

Susan Weiner
2007-06-01
Full Text Available Modiano's methods in Dora Bruder recall the Annales historiographer's rejection of the history of events in favor of the "long duration," but with human history as its object. Modiano's long duration draws out repetitions and variations between his own life and Dora's as he reconstructs and imagines it, between Dora and fictional characters, between Dora's story and the lives of Holocaust victims and survivors known and unknown. Moreover, the author encourages the reader to take part in the uncanny connections the novel makes, through movements of the imagination not unlike Modiano's own. In so doing, we approach Dora and those who shared her fate through their lives rather than their death, restoring to them the everyday freedom of their thoughts and actions alongside our own.

Imaging of uretero-pelvic junction obstruction with stimulated diuresis
International Nuclear Information System (INIS)
Ebel, K.D.; Bliesener, J.A.; Gharib, M.
1988-01-01
Eighty-nine kidneys of 81 infants and children with uretero-pelvic junction obstruction were investigated using ultrasonography (US), diuretic urography (DUR) and diuretic renography (DREN). Results of the US were false-negative in 14%. This can be avoided by ensuring that the patients get an amount of fluid appropriate to their age before the examination or by performing diuretic ultrasonography with frusemide. False-positive results were found with US in 15%, but obstruction was excluded by using the DUR and/or the DREN. During post-operative follow-up the DUS is useful and after 6 months the clearance with 123-iodine hippurate combined with the DREN should be performed. The administration of the Whitaker-test is unnecessary. (orig.)

Full Text Available BACKGROUND: Owing to their important function in regulating cell death, pharmacological inhibition of Bcl-2 proteins by dubbed BH3-mimetics is a promising strategy for apoptosis induction or sensitization to chemotherapy. However, the role of Apaf-1, the main protein constituent of the apoptosome, in the process has yet not been analyzed. Furthermore as new chemotherapeutics develop, the possible chemotherapy-induced toxicity to rapidly dividing normal cells, especially sensitive differentiated cells, has to be considered. Such undesirable effects would probably be ameliorated by selectively and locally inhibiting apoptosis in defined sensitive cells. METHODOLOGY AND PRINCIPAL FINDINGS: Mouse embryonic fibroblasts (MEFS from Apaf-1 knock out mouse (MEFS KO Apaf-1 and Bax/Bak double KO (MEFS KO Bax/Bak, MEFS from wild-type mouse (MEFS wt and human cervix adenocarcinoma (HeLa cells were used to comparatively investigate the signaling cell death-induced pathways of BH3-mimetics, like ABT737 and GX15-070, with DNA damage-inducing agent cisplatin (cis-diammineplatinum(II dichloride, CDDP. The study was performed in the absence or presence of apoptosis inhibitors namely, caspase inhibitors or apoptosome inhibitors. BH3-mimetic ABT737 required of Apaf-1 to exert its apoptosis-inducing effect. In contrast, BH3-mimetic GX15-070 and DNA damage-inducing CDDP induced cell death in the absence of both Bax/Bak and Apaf-1. GX15-070 induced autophagy-based cell death in all the cell lines analyzed. MEFS wt cells were protected from the cytotoxic effects of ABT737 and CDDP by chemical inhibition of the apoptosome through QM31, but not by using general caspase inhibitors. CONCLUSIONS: BH3-mimetic ABT737 not only requires Bax/Bak to exert its apoptosis-inducing effect, but also Apaf-1, while GX15-070 and CDDP induce different modalities of cell death in the absence of Bax/Bak or Apaf-1. Inclusion of specific Apaf-1 inhibitors in topical and well

Biotechnological challenges of bioartificial kidney engineering.
Jansen, J; Fedecostante, M; Wilmer, M J; van den Heuvel, L P; Hoenderop, J G; Masereeuw, R
2014-11-15
With the world-wide increase of patients with renal failure, the development of functional renal replacement therapies have gained significant interest and novel technologies are rapidly evolving. Currently used renal replacement therapies insufficiently remove accumulating waste products, resulting in the uremic syndrome. A more preferred treatment option is kidney transplantation, but the shortage of donor organs and the increasing number of patients waiting for a transplant warrant the development of novel technologies. The bioartificial kidney (BAK) is such promising biotechnological approach to replace essential renal functions together with the active secretion of waste products. The development of the BAK requires a multidisciplinary approach and evolves at the intersection of regenerative medicine and renal replacement therapy. Here we provide a concise review embracing a compact historical overview of bioartificial kidney development and highlighting the current state-of-the-art, including implementation of living-membranes and the relevance of extracellular matrices. We focus further on the choice of relevant renal epithelial cell lines versus the use of stem cells and co-cultures that need to be implemented in a suitable device. Moreover, the future of the BAK in regenerative nephrology is discussed. Copyright © 2014 Elsevier Inc. All rights reserved.

The purpose of this study was to find differences in general life satisfaction in adolescents with mild intellectual disability (MID) with respect to exhibiting a prosocial or an antisocial coping style. According to the ecological approach, using the antisocial style in a competitive school environment (a zero-sum game) may increase personal satisfaction, while in the family, which operates on the principles of 'common good' or 'common failure' (a non-zero-sum game), the antisocial style may reduce general satisfaction of the individual. However, according to the self-regulatory approach, antisocial coping in interactions with parents and teachers in adolescence may increase life satisfaction as it heightens the individual's sense of autonomy. The differences between the two approaches in the hypothesised influence of a particular coping style on life satisfaction led us to conduct empirical research. A total of 151 students with MID were qualified for the final study (75 females and 76 males). The age of the examined group varied from 18 to 22 years. The study was conducted using the R-PDPI test, which is based on the Strategic Approach to Coping Scale by Hobfoll (). The test measures coping with domination and humiliation from parents and teachers as well as isolation and humiliation from peers (Kurtek ). Next, the Index of General Affect by Campbell et al. () was used to assess general life satisfaction. Generally, a positive relationship between the indirect prosocial style and life satisfaction was found. Also, the results indicate that using the prosocial coping style to deal with humiliating acts of the mother and dominant acts of the father was connected with increased general life satisfaction, whereas the antisocial coping style employed in these situations - with a lower level of satisfaction. Moreover, it was found that general life satisfaction was positively related to passive and suppressive coping styles but negatively correlated with the

Profiles in the offending process of nonserial sexual murderers.
Beauregard, Eric; Proulx, Jean
2002-08-01
The aim of this study was to investigate specific pathways in the offending processes of nonserial sexual murderers and to examine possible relationships with different precrime, per-crime, and postcrime factors. Included in this study were 36 offenders who have committed at least one sexual murder against a female victim and they were classified using cluster analysis. Participants using the sadistic pathway planned their offenses and used physical restraints during the offenses. Furthermore, they mutilated and humiliated their victims. Finally, they hid the bodies of the victims. Participants using the anger pathway had not premeditated the homicide. Mutilation, humiliation, and physical restraints were less predominant with these participants than with those using the sadistic pathway. Moreover, these offenders were more likely to leave the bodies at the crime scenes after the killings occurred. These two profiles are compared with empirical studies addressing sexual homicide.

We investigated the inhibitory effects of antibacterial, biocidal, and antifungal agents against Fusarium spp. Seven Fusarium spp: four F. falciforme (Fusarium solani species complex), one Fusarium spp, one Fusarium spp. (Fusarium incarnatum-equiseti species complex), and one F. napiforme (Gibberella fujikuroi species complex), isolated from eyes with fungal keratitis were used in this study. Their susceptibility to antibacterial agents: flomoxef, imipenem, gatifloxacin, levofloxacin, moxifloxacin, gentamicin, tobramycin, and Tobracin® (contained 3,000 μg/ml of tobramycin and 25 μg/ml of benzalkonium chloride (BAK), a biocidal agent: BAK, and antifungal agents: amphotericin B, pimaricin (natamycin), fluconazole, itraconazole, miconazole, voriconazole, and micafungin, was determined by broth microdilution tests. The half-maximal inhibitory concentration (IC50), 100% inhibitory concentration (IC100), and minimum inhibitory concentration (MIC) against the Fusarium isolates were determined. BAK had the highest activity against the Fusarium spp. except for the antifungal agents. Three fluoroquinolones and two aminoglycosides had inhibitory effects against the Fusarium spp. at relatively high concentrations. Tobracin® had a higher inhibitory effect against Fusarium spp. than tobramycin alone. Amphotericin B had the highest inhibitory effect against the Fusarium spp, although it had different degrees of activity against each isolate. Our findings showed that fluoroquinolones, aminoglycosides, and BAK had some degree of inhibitory effect against the seven Fusarium isolates, although these agents had considerably lower effect than amphotericin B. However, the inhibitory effects of amphotericin B against the Fusarium spp. varied for the different isolates. Further studies for more effective medications against Fusarium, such as different combinations of antibacterial, biocidal, and antifungal agents are needed. © The Author 2015.

Full Text Available Summary: Developmental morphogenesis, tissue injury, and oncogenic transformation can cause the detachment of epithelial cells. These cells are eliminated by a specialized form of apoptosis (anoikis. While the processes that contribute to this form of cell death have been studied, the underlying mechanisms remain unclear. Here, we tested the role of the cJUN NH2-terminal kinase (JNK signaling pathway using murine models with compound JNK deficiency in mammary and kidney epithelial cells. These studies demonstrated that JNK is required for efficient anoikis in vitro and in vivo. Moreover, JNK-promoted anoikis required pro-apoptotic members of the BCL2 family of proteins. We show that JNK acts through a BAK/BAX-dependent apoptotic pathway by increasing BIM expression and phosphorylating BMF, leading to death of detached epithelial cells. : Developmental morphogenesis, tissue injury, and oncogenic transformation can cause epithelial cell detachment. These cells are eliminated by a specialized form of apoptosis termed anoikis. Girnius and Davis show that anoikis is mediated by the cJUN NH2-terminal kinase (JNK, which increases BIM expression and phosphorylates BMF to engage BAK/BAX-dependent apoptosis.

Effect of human milk as a treatment for dry eye syndrome in a mouse model.
Diego, Jose L; Bidikov, Luke; Pedler, Michelle G; Kennedy, Jeffrey B; Quiroz-Mercado, Hugo; Gregory, Darren G; Petrash, J Mark; McCourt, Emily A
Dry eye syndrome (DES) affects millions of people worldwide. Homeopathic remedies to treat a wide variety of ocular diseases have previously been documented in the literature, but little systematic work has been performed to validate the remedies' efficacy using accepted laboratory models of disease. The purpose of this study was to evaluate the efficacy of human milk and nopal cactus (prickly pear), two widely used homeopathic remedies, as agents to reduce pathological markers of DES. The previously described benzalkonium chloride (BAK) dry eye mouse model was used to study the efficacy of human milk and nopal cactus (prickly pear). BAK (0.2%) was applied to the mouse ocular surface twice daily to induce dry eye pathology. Fluorescein staining was used to verify that the animals had characteristic signs of DES. After induction of DES, the animals were treated with human milk (whole and fat-reduced), nopal, nopal extract derivatives, or cyclosporine four times daily for 7 days. Punctate staining and preservation of corneal epithelial thickness, measured histologically at the end of treatment, were used as indices of therapeutic efficacy. Treatment with BAK reduced the mean corneal epithelial thickness from 36.77±0.64 μm in the control mice to 21.29±3.2 μm. Reduction in corneal epithelial thickness was largely prevented by administration of whole milk (33.2±2.5 μm) or fat-reduced milk (36.1±1.58 μm), outcomes that were similar to treatment with cyclosporine (38.52±2.47 μm), a standard in current dry eye therapy. In contrast, crude or filtered nopal extracts were ineffective at preventing BAK-induced loss of corneal epithelial thickness (24.76±1.78 μm and 27.99±2.75 μm, respectively), as were solvents used in the extraction of nopal materials (26.53±1.46 μm for ethyl acetate, 21.59±5.87 μm for methanol). Epithelial damage, as reflected in the punctate scores, decreased over 4 days of treatment with whole and fat-reduced milk but continued to

Toward tsunami early warning system in Indonesia by using rapid rupture durations estimation
International Nuclear Information System (INIS)
Madlazim
2012-01-01
Indonesia has Indonesian Tsunami Early Warning System (Ina-TEWS) since 2008. The Ina-TEWS has used automatic processing on hypocenter; Mwp, Mw (mB) and Mj. If earthquake occurred in Ocean, depth 7, then Ina-TEWS announce early warning that the earthquake can generate tsunami. However, the announcement of the Ina-TEWS is still not accuracy. Purposes of this research are to estimate earthquake rupture duration of large Indonesia earthquakes that occurred in Indian Ocean, Java, Timor sea, Banda sea, Arafura sea and Pasific ocean. We analyzed at least 330 vertical seismogram recorded by IRIS-DMC network using a direct procedure for rapid assessment of earthquake tsunami potential using simple measures on P-wave vertical seismograms on the velocity records, and the likelihood that the high-frequency, apparent rupture duration, T dur . T dur can be related to the critical parameters rupture length (L), depth (z), and shear modulus (μ) while T dur may be related to wide (W), slip (D), z or μ. Our analysis shows that the rupture duration has a stronger influence to generate tsunami than Mw and depth. The rupture duration gives more information on tsunami impact, Mo/μ, depth and size than Mw and other currently used discriminants. We show more information which known from the rupture durations. The longer rupture duration, the shallower source of the earthquake. For rupture duration greater than 50 s, the depth less than 50 km, Mw greater than 7, the longer rupture length, because T dur is proportional L and greater Mo/μ. Because Mo/μ is proportional L. So, with rupture duration information can be known information of the four parameters. We also suggest that tsunami potential is not directly related to the faulting type of source and for events that have rupture duration greater than 50 s, the earthquakes generated tsunami. With available real-time seismogram data, rapid calculation, rupture duration discriminant can be completed within 4–5 min after an earthquake

The aim of this study was to further elucidate the mechanisms of dual-phase technetium-99m methoxyisobutylisonitrile (Tc-MIBI) parathyroid imaging by exploring the association between early uptake results (EUR), delayed uptake results (DUR), and the retention index (RI) in dual-phase Tc-MIBI parathyroid imaging and P glycoprotein (P-gp), multidrug resistance-associated protein 1 (MRP1), and glutathione S-transferase-π (GST-π) expression in hyperparathyroidism (HPT). Preoperative dual-phase (early and delayed) Tc-MIBI imaging was performed on 74 patients undergoing parathyroidectomy for HPT. EUR, DUR, and RI were calculated. P-gp, MRP1, and GST-π expressions were assessed using immunohistochemistry in resected tissue from HPT and control patients. The association between P-gp, MRP1, and GST-π expressions and EUR, DUR, and RI in HPT was evaluated. The positive rate of dual-phase T c-MIBI imaging was 91.89% (68/74) and the false-negative rate was 8.11% (6/74). P-gp and GST-π expressions were higher in tissues resected from control compared with HPT patients (47.37 and 81.5%, P<0.05); there was no difference in MRP1. EUR were associated with P-gp and GST-π expressions, and DUR were associated with MRP1 expression. There was a significant difference in MRP1 expression between RI greater than or equal to 0 and RI less than 0. There was no relationship between the sensitivity of dual-phase Tc-MIBI imaging and P-gp, MRP1, and GST-π expressions in resected parathyroid tissue. The six false-negative HPT cases consisted of three P-gp (-)/MRP1 (-) tissues, three P-gp (-)/GST-π (-) tissues, and four MRP1 (-)/GST-π (-) tissues. As P-gp and GST-π expressions were higher in tissues resected from control compared with HPT patients, Tc-MIBI may wash out faster from normal parathyroid tissue surrounding the lesion compared with the lesion itself, facilitating detection.

The Longue Durée of Black Lives Matter.
Nelson, Alondra
2016-10-01
Black Lives Matter was first articulated just a few years ago, but it has been the leitmotif of antiracist struggles for generations. The Movement for Black Lives extends the work of previous movements that challenged forms of oppression that act on Black bodies with impunity. It should be understood in the context of Ida B. Wells' anti-lynching campaign, Fannie Lou Hamer's reproductive justice demands, and the Black Panther Party's health activism. The 50th anniversary of the Black Panther Party is an occasion to recall that its work confronted the callous neglect and the corporeal surveillance and abuse of poor Black communities. Similar demands have been the centrifugal force of social movements that for centuries have refused to have Black lives cast beyond the human boundary.

Full Text Available The Geomagnetic storms are considered as one of the major natural hazards. Egyptian geomagnetic observatories observed multiple geomagnetic storms during 18 February to 2 March 2014. During this period, four interplanetary shocks successively hit the Earth’s magnetosphere, leading to four geomagnetic storms. The storm onsets occurred on 18, 20, 23 and 27 February. A non-substorm Pi2 pulsation was observed on 26 February. This Pi2 pulsation was detected in Egyptian observatories (Misallat and Abu Simbel, Kakioka station in Japan and Carson City station in US with nearly identical waveforms. Van Allen Probe missions observed non-compressional Pc4 pulsations on the recovery phase of the third storm. This Pc4 event is may be likely attributed to the decay of the ring current in the recovery phase.

Design and Evaluation of Voriconazole Eye Drops for the Treatment of Fungal Keratitis
Directory of Open Access Journals (Sweden)
Sakshi Malhotra
2014-01-01
Full Text Available Voriconazole is a novel antifungal agent with excellent broad spectrum activity commercially available for oral and intravenous administration. The purpose of this study was to prepare ophthalmic formulation of hydroxypropyl beta cyclodextrin (HP-β-CD based voriconazole containing benzalkonium chloride BAK and EDTA with or without viscosity modifiers and study its permeation characteristics through freshly excised goat cornea. The results were observed that viscosity and force of bioadhesion of the voriconazole HP-β-CD solutions containing xanthan gum (XG are more as compared to polyvinyl alcohol. The results revealed that voriconazole drop containing PVA provided least viscosity and higher corneal permeation of drug, while drop formulated with XG had maximum viscosity and least permeation. The HP-β-CD based voriconazole (1.5% ophthalmic formulation containing xanthan gum (1.5, preserved with BAK and EDTA, could provide shelf life of 2 years. The microbiological studies showed that voriconazole ophthalmic solution containing xanthan gum shows better antifungal activity as compared to voriconazole and xanthan gum alone. Thus, it can be concluded that HP-β-CD based voriconazole (1.5%, pH 7.0 ophthalmic solution containing BAK and EDTA with viscosity modifier XG provided maximum precorneal residence time as compared to other viscosity modifiers and polyvinyl alcohol provided less precorneal residence time than other viscosity modifiers.

Extracellular matrix (ECM) coatings have been used to improve cell performance in bioartificial kidneys (BAKs). However, their effects on primary human renal proximal tubule cells (HPTCs), which is the most important cell type with regard to clinical applications, have not been tested systematically. Also, the effects of ECM coatings on cell performance during extended time periods have not been addressed. Studying such effects is important for the development of long-term applications. Herein we analyzed for the first time systematically the effects of ECM coatings on proliferation and differentiation of human renal cells and we addressed, in particular, formation and long-term maintenance of differentiated epithelia. Our study focused on HPTCs. ECM coatings were tested alone or in combination with the growth factor bone morphogenetic protein-7 and other additives. The best results were obtained with ECMs consisting of the basal lamina components, laminin or collagen IV, and differentiated epithelia could be maintained up to three weeks on these ECMs. These results provide for the first time clear evidence which kinds of ECM coatings are most appropriate for BAKs. The results also showed that alpha-SMA-expressing myofibroblasts played a key role in the final disruption of differentiated epithelia. This suggests that epithelial-to-mesenchymal transition-related processes might be the major obstacle in long-term applications and such processes should be carefully addressed in future BAK-related research.

In nature, adult mosquitoes typically utilize nectar as their main energy source, but they can switch to other as yet unidentified sugary fluids. Contemporary lifestyles, with their associated unwillingness to consume leftovers and improper disposal of waste, have resulted in the disposal of huge amounts of waste into the environment. Such refuse often contains unfinished food items, many of which contain sugar and some of which can collect water from rain and generate juices. Despite evidence that mosquitoes can feed on sugar-rich suspensions, semi-liquids, and decaying fruits, which can be abundant in garbage sites, the impacts of sweet waste fluids on dengue vectors are unknown. Here, we investigated the effects of extracts from some familiar sweet home waste items on key components of vectorial capacity of Aedes aegypti. Adult mosquitoes were fed one of five diets in this study: water (WAT); sucrose (SUG); bakery product (remnant of chocolate cake, BAK); dairy product (yogurt, YOG); and fruit (banana (BAN). Differences in survival, response time to host, and egg production were examined between groups. For both males and females, maintenance on BAK extract resulted in marked survival levels that were similar to those seen with SUG. Sweet waste extracts provided better substrates for survival compared to water, but this superiority was mostly seen with BAK. Females maintained on BAK, YOG, and BAN exhibited shorter response times to a host compared to their counterparts maintained on SUG. The levels of egg production were equivalent in waste extract- and SUG-fed females. The findings presented here illustrate the potential of sweet waste-derived fluids to contribute to the vectorial capacity of dengue vectors and suggest the necessity of readdressing the issue of waste disposal, especially that of unfinished sweet foods. Such approaches can be particularly relevant in dengue endemic areas where rainfall is frequent and waste collection infrequent. Copyright

The purpose of this study was to develop and implement the clinical decision support system (CDSS) for oncology nurses in the care of patients with cancer and to explore the nurses' experiences about the system. The study was conducted using a mixed-methods research design with 14 nurses working at a gynecological oncology clinic at a university hospital in Turkey. The nurses stated that they did not experience any problems during the implementation of the CDSS, and its usage facilitated the assessment of patients' needs and care management. The results indicated that the CDSS supported the nurses' decision-making process about patients' needs and preparation of individual care plans. The CDSS should be developed and implemented by the nurses working with patients with cancer. AMAÇ: Amaç kanser hastalarının bakımına yönelik klinik karar destek sistemi oluşturmak, uygulamak (KKDS) ve sistemi kullanan hemşirelerin deneyimlerini incelemektir. YÖNTEM: Çalışma kalitatif ve kantitatif araştırma yöntemleri kullanılarak Türkiyede'ki bir üniversite hastanesinin jinekolojik onkoloji servisinde çalışan 14 hemşire ile yürütülmüştür.

Purpose In numerous clinical and experimental studies, preservatives present in eye drops have had detrimental effects on ocular epithelial cells. The aim of this study was to compare the cytotoxic and inflammatory effects of the preservative polyquaternium-1 (PQ-1) containing Travatan (travoprost 0.004%) and Systane Ultra eye drops with benzalkonium chloride (BAK) alone or BAK-preserved Xalatan (0.005% latanoprost) eye drops in HCE-2 human corneal epithelial cell culture. Methods HCE-2 cells were exposed to the commercial eye drops Travatan, Systane Ultra, Xalatan, and the preservative BAK. Cell viability was determined using colorimetric MTT (3-(4,5-dimethyldiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay and by release of lactate dehydrogenase (LDH). Induction of apoptosis was measured with a using a colorimetric caspase-3 assay kit. DNA binding of the nuclear factor kappa B (NF-κB) transcription factor, and productions of the proinflammatory cytokines, interleukins IL-6 and IL-8, were determined using an enzyme-linked immunosorbent assay (ELISA) method. Results Cell viability, as measured by the MTT assay, declined by up to 50% after exposure to Travatan or Systane Ultra solutions which contain 0.001% PQ-1. BAK at 0.02% rather than at 0.001% concentration evoked total cell death signs on HCE-2 cells. In addition, cell membrane permeability, as measured by LDH release, was elevated by sixfold with Travatan and by a maximum threefold with Systane Ultra. Interestingly, Travatan and Systane Ultra activated NF-κB and elevated the secretion of inflammation markers IL-6 by 3 to eightfold and IL-8 by 1.5 to 3.5 fold, respectively, as analyzed with ELISA. Conclusions Eye drops containing PQ-1 evoke cytotoxicity and enhance the NF-κB driven inflammation reaction in cultured HCE-2 cells. Our results indicate that these harmful effects of ocular solutions preserved with PQ-1 should be further evaluated in vitro and in vivo. PMID:22605930

Full Text Available Öz İnsanın yaşam tarzı, tarihi, kültürü, hayata bakış açısı dilde yansıtılır. Atalarımızdan bize aktarılan ve anların üzün süre gözlemleyip bir sonuca vararak öğüt ve nasihat şeklinde aktarmış oldukları özlü sözlerdir. Atasözleri değişik dillerde farklı terimlerle telaffuz edilmiştir; Türkçede ise Kaşkarlı Mahmut sav şeklinde ifade ederken daha sonraları Osmanlı Türkçesinde ise darbımesel veya durûb-i emsal kelime grubuyla ifade edilmiştir. Günümüz Türkçesinde ise atasözü şeklinde söylenmektedir. Azerbaycan Türkçesinde ise Atalar sözü terimiyle ifade edilmektedir. Atasözleri toplumda yaşanan olaylardan çıkarılması gereken dersleri bir nasihat bir öğüt şeklinde kısaca anlatır, dile getirir. O nedenle atasözlerini deyimlerden ayıran en önemli tarafı atasözlerinin bir yargı bildirmesidir. Bu öğüt bütün toplumu kapsar ve her zaman doğruya ve iyiye yönlendirir. Diğer taraftan değişik Türk toplulukları kendi atasözlerini toplamışlar ve üzerinde dil çalışmaları yapmışlardır. Bu bakımdan atasözleri ve deyimlerin incelenmesi özel önem taşımaktadır. Türkiye ve Azerbaycan tarihten bu güne hem dilde hem de kültürde birlikteliği sağlamış iki devlettir. Aynı dili konuşmamızın yanında farklı komşuluk ilişkilerine sahip olmamız ve farklı kültürlerden etkilenmemiz nedeni ile hem dilde hem de kültürde azda olsa farklılıklar vardır. Bu farklılıklar atasözlerinde de görülmektedir.

Full Text Available O problema sobre o tempo é um tema complexo e bastante estudado tanto no âmbito científico como na tradição filosófica. Henri Bergson, utilizando-se do tempo proposto por Albert Einstein, traça diferenças entre o tempo heterogêneo, ou cronológico, e o tempo homogêneo, ou durée, sendo este segundo, o menos estudado pelo físico. Foi a partir da duração que o filósofo propõe-se a mostrar como se dá a concepção do tempo durée e como esta forma responde a um questionamento einsteiniano. O presente artigo pretende estabelecer um diálogo entre a concepção de tempo de ambos autores, ressaltando a novidade da duração bergsoniana.

This study investigated the effects of manipulating the load components of aerobic training sessions on the physical performance of rats. To achieve this purpose, adult male Wistar rats were divided into four groups: an untrained control (CON) group and training groups with a predominant overload in intensity (INT) or duration (DUR) or alternating and similar overloads in intensity and duration (ID). Prior to, during, and after 8 weeks of the control or training protocols, the performance of the rats (evaluated by their workload) was determined during fatiguing, incremental-speed treadmill running. Two additional incremental running tests were performed prior to and at the end of the protocols to measure the peak rate of oxygen consumption (VO2peak). As expected, the rats in the trained groups exhibited increased performance, whereas the untrained rats showed stable performance throughout the 8 weeks. Notably, the performance gain exhibited by the DUR rats reached a plateau after the 4th week. This plateau was not present in the INT or ID rats, which exhibited increased performance at the end of training protocol compared with the DUR rats. None of the training protocols changed the VO2peak values; however, these values were attained at faster speeds, which indicated increased running economy. In conclusion, our findings demonstrate that the training protocols improved the physical performance of rats, likely resulting from enhanced running economy. Furthermore, compared with overload in duration, overload in the intensity of training sessions was more effective at inducing performance improvements across the 8 weeks of the study.

Optimization of benzalkonium chloride (alkyl dimethylbenzylammonium chloride: BAK) concentration as preservative in 0.0015% tafluprost ophthalmic solution (Tapros 0.0015% ophthalmic solution), an anti-glaucoma medicine, was examined from the points of ocular surface safety and preservative efficacy. BAKC(12), which is dodecyl dimethylbenzylammonium chloride, and BAKmix, which is the mixture of dodecyl, tetradecyl and hexadecyl dimethylbenzylammonium chloride were used in this study. The effects of BAKC(12) concentrations and the BAK types, BAKC(12) and BAKmix, in tafluprost ophthalmic solution on ocular surface safety were evaluated using the in vitro SV 40-immobilized human corneal epithelium cell line (HCE-T). Following treatments of Tafluprost ophthalmic solutions with BAKC(12), its concentration dependency was observed on cell viability of HCE-T. The cell viability of HCE-T after treatment of these solutions with 0.001% to 0.003% BAKC(12) for 5 minutes were the same level as that after treatment of the solution without BAK. Tafluprost ophthalmic solution with 0.01% BAKC(12) was safer for the ocular surface than the same solution with 0.01% BAKmix. Preservatives-effectiveness tests of tafluprost ophthalmic solutions with various concentrations of BAKC(12) were performed according to the Japanese Pharmacopoeia (JP), and solutions with more than 0.0005% BAKC(12) conformed to JP criteria. It was concluded that 0.0005% to 0.003% of BAKC(12) in tafluprost ophthalmic solution was optimal, namely, well-balanced from the points of ocular surface safety and preservative efficacy.

Cytotoxicity and mutagenicity of opthalmic solution preservatives and UVA radiation in L5178Y cells
International Nuclear Information System (INIS)
Withrow, T.J.; Brown, N.T.; Hitchins, V.M.; Strickland, A.G.
1989-01-01
Four preservatives used in ophthalmic solutions were tested for toxic and mutagenic potential in mouse lymphoma cells with and without exposure of cells to ultraviolet A (UVA) radiation. The preservatives tested were benzalkonium chloride (BAK), chlorhexidine, thimerosal and ethylenediaminetetraacetic acid (EDTA). Cell survival and mutagenesis were measured using the L5178Y mouse lymphoma (TK +/- ) system. Cells were exposed to varying amounts of preservatives for 1 h at 37 0 C, and aliquots irradiated with UVA radiation (during exposure to preservative). Cells were then assayed for survival, and mutagenesis at the thymidine kinase (TK) locus. In concentrations commonly found in ophthalmic solutions, BAK, chlorhexidine, and thimerosal were toxic to cells, and thimerosal was slightly mutagenic. When cells were exposed to preservative and UVA radiation, chlorhexidine was mutagenic and the mutagenic activity of thimerosal was enhanced. (author)

Sermo humilis and lyricism in Italianesi by Saverio La Ruina
Directory of Open Access Journals (Sweden)
Angela Albanese
2014-05-01
Full Text Available The article discusses Italianesi, the theatrical monologue composed in 2011 and performed by Calabrian storyteller Saverio La Ruina, that presents in first person the life story of Tonino Cantisani, born in 1951 in an Albanian prison camp to an Italian soldier and an Albanian mother. Although Tonino is a fictional creation, through his protagonist La Ruina gives voice to a true story, a postwar tragedy of denied identity that official histories on both sides of the Cold War have preferred to forget. Suspected of subversion because of their ties to Italy, mother and son are incarcerated by the Albanian communist regime for over forty years, until the death of dictator Enver Hoxha opens the borders and compels Tonino to migrate to Italy. But while he had spent the first half of his life ostracized as an Italian in Albania, he discovers that his new homeland marginalizes him as well, shunning him as an Albanian in Italy. But Tonino and those he represents are redeemed through the profound, haunting simplicity of the Calabro-Italian dialect that La Ruina has invented for him, inserted in a narrative architecture based on a rhetoric of reticence and modesty, where words and silence joined to minimal, essential gestures and movements create a unique, organic discourse of great evocative power.

What's Manifest in the History of SciTech: Reflections on The History Manifesto.
Kevles, Daniel J
2016-06-01
Making nuts-and-bolts public policy is not--and never has been--the long suit of professional historians, but general historical work, whatever its durée, has done a good deal to shape discourse on public issues. Jo Guldi and David Armitage neglect that fact, as well as the opinion-shaping influence of history conveyed via nonprint media. They also ignore the large body of scholarship produced in all media during recent decades in the history of science, technology, and science-related medicine (SciTech), even though SciTech itself looms enormously large in the modern era as an instrument of national and international security, a driver of the economy, and a transformer of medicine, public health, and the environment. Much of this scholarship, even though of short durée, can illuminate salient contemporary issues, including innovation; patronage and practice; government and policy; imperialism and globalization; intellectual property; science and religion; and human rights, environment, energy, and disasters.

In this paper, we systematically investigate the electronic structure for the 2 Σ + ground state of the polar alkali-metal-alkaline-earth-metal molecules BaAlk (Alk = Li, Na, K, Rb, and Cs). Potential energy curves and permanent dipole moments (PDMs) are determined using power quantum chemistry complete active space self-consistent field and multi-reference configuration interaction methods. Basic spectroscopic constants are derived from ro-vibrational bound state calculation. From the calculations, it is shown that BaK, BaRb, and BaCs molecules have moderate values of PDM at the equilibrium bond distance (BaK:1.62 D, BaRb:3.32 D, and BaCs:4.02 D). Besides, the equilibrium bond length (4.93 Å and 5.19 Å) and dissociation energy (0.1825 eV and 0.1817 eV) for the BaRb and BaCs are also obtained

The aim of this study was to analyze the effect of azithromycin (AZM) 1% ophthalmic solution in DuraSite® (AzaSite®) on biofilm formation by Staphylococcus aureus and coagulase-negative staphylococci in vitro. Susceptible and resistant clinical strains (n = 8) of S. aureus and coagulase-negative staphylococci were challenged with serial dilutions of AzaSite® and its components: AZM, benzalkonium chloride (BAK), and the DuraSite drug delivery vehicle. After 20 h of incubation, bacterial growth was quantified using a spectrophotometer (A = 600 nm). Plates were stained with crystal violet and biofilm formation was quantified spectrophotometrically at A = 590 nm. AzaSite® and AZM inhibited bacterial growth (P reduction in biofilm formation (P reduction in biofilm formation at concentrations from 1.25 to 10 mg/mL in most strains. DuraSite® inhibited biofilm formation at concentrations between 10% and 2.5% in all studied strains (P < 0.05), without affecting bacterial growth. BAK inhibited bacterial growth and biofilm formation in all strains between concentrations of 0.042 and 0.375 mg/mL (P < 0.05). AzaSite®, AZM, or BAK prevented biofilm formation by inhibiting growth of AZM-susceptible strains. AzaSite®, AZM, and DuraSite® also reduced biofilm formation at subinhibitory concentrations for growth. Our data indicate that AZM has a moderate inhibitory effect on biofilm formation, whereas DuraSite® appears to play a greater role in the inhibition of staphylococcal biofilm formation by AzaSite®.

Prostaglandin analogs reduce intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension; however, these medications may affect the ocular surface and elicit ocular discomfort when preserved with benzalkonium chloride (BAK). This was an open-label, single-arm study conducted in Latin America from February 2012 to May 2013. Patients with open-angle glaucoma or ocular hypertension who were intolerant of latanoprost 0.005 % were transitioned to receive once-daily BAK-free travoprost 0.004 % containing polyquaternium-1 (Travatan® preserved with POLYQUAD® [PQ], Alcon Laboratories, Inc; Fort Worth, TX) for 12 weeks. Mean change in IOP from baseline (primary efficacy endpoint) and the percentage of patients who achieved a target IOP of ≤18 mmHg were evaluated at all on-therapy visits. Ocular hyperemia, patient preference, and self-projected adherence were assessed at week 12. Adverse events (AEs) were monitored throughout the study. All enrolled patients were included in the analysis (n = 191); the majority of patients (90.6 %, n = 173/191) completed the study. Mean (SD) patient age was 67.5 (11.3) years, and mean baseline IOP was 14.8 mmHg. Mean IOP was reduced by 0.94 mmHg at week 6 and by 1.09 mmHg at week 12 (P glaucoma or ocular hypertension who were intolerant of latanoprost. BAK-free travoprost 0.004 % is a viable alternative for patients who require switching their IOP-lowering medications because of tolerability issues. ClinicalTrials.gov identifier, NCT01510145.

Plants have evolved two tiers of immune receptors to detect infections: cell surface-resident pattern recognition receptors (PRRs) that sense microbial signatures and intracellular nucleotide binding domain leucine-rich repeat (NLR) proteins that recognize pathogen effectors. How PRRs and NLRs interconnect and activate the specific and overlapping plant immune responses remains elusive. A genetic screen for components controlling plant immunity identified ANXUR1 (ANX1), a malectin-like domain-containing receptor-like kinase, together with its homolog ANX2, as important negative regulators of both PRR- and NLR-mediated immunity in Arabidopsis thaliana ANX1 constitutively associates with the bacterial flagellin receptor FLAGELLIN-SENSING2 (FLS2) and its coreceptor BRI1-ASSOCIATED RECEPTOR KINASE1 (BAK1). Perception of flagellin by FLS2 promotes ANX1 association with BAK1, thereby interfering with FLS2-BAK1 complex formation to attenuate PRR signaling. In addition, ANX1 complexes with the NLR proteins RESISTANT TO PSEUDOMONAS SYRINGAE2 (RPS2) and RESISTANCE TO P. SYRINGAE PV MACULICOLA1. ANX1 promotes RPS2 degradation and attenuates RPS2-mediated cell death. Surprisingly, a mutation that affects ANX1 function in plant immunity does not disrupt its function in controlling pollen tube growth during fertilization. Our study thus reveals a molecular link between PRR and NLR protein complexes that both associate with cell surface-resident ANX1 and uncovers uncoupled functions of ANX1 and ANX2 during plant immunity and sexual reproduction. © 2017 American Society of Plant Biologists.

Full Text Available A revision of the genus Asparagus in South Africa, South West Africa, Bechuanaland, Basutoland, and Swaziland has been undertaken. Notes are given on the value of most o f the characters which have been used in the separation of species, recent literature on the nature of Asparagus assimilatory organs, and a technique for the examination of chromosomes. Chromosome counts are listed for ten taxa. There is a key to the forty species and four varieties. In the main part of the work these taxa are described, and their synonymy, taxonomy, distribution and habitats dealt with. Six species and one variety are new. The following are the new species and combinations: A. setaceus (Kunth (Asparagopsis setacea Kunth, A. mueronatus, A. macowanii Bak. var. zuluensis (N. E. Br. (A. zuluensis N. E.

To use any domestic remedy, specific knowledge and skills are required. Simple logic dictates that the use of wild plants in the context of limited interaction with nature requires prior identification, while in the case of non-plant remedies and cultivated plants this step can be omitted. This paper aims to document the current and past uses of non-plant remedies and cultivated plants in the study region for human/animal medication; to analyze the human medicinal and veterinary use areas in the context of the remedy groups; to qualitatively compare the results with relevant historical publications; and to compare the intensity and purpose of use between the remedy groups. During field studies 134 semi-structured interviews were conducted with locals from 11 villages in the Liubań district of Belarus. Currently used home-remedies as well as those used in the past were documented by employing the folk history method. The subject was approached through health-related uses, not by way of remedies. Interview records were digitalized and structured in Detailed Use Records in order to ascertain local perceptions. An Informant Consensus Factor (FIC) was calculated for remedy groups as well as for different use categories. In the human medication area the use of nearby remedies was neither very diverse nor numerous: 266 DUR for 45 taxa belonging to 27 families were recorded for cultivated plants along with 188 DUR for 58 different non-plant remedies. The FIC values for both remedy groups were lower than for wild plants. In the ethnoveterinary medicine use area there were 48 DUR referring to the use of 14 cultivated plant taxa from 12 families and 72 DUR referring to the use of 31 non-plant remedies. The FIC value for the whole veterinary use area of cultivated plants was relatively low, yet similar to the FIC of wild plants. Differences between remedy groups were pronounced, indicating that in domestic human medicine cultivated plants and non-plant remedies are either

To investigate the effectiveness of a high-affinity human monoclonal antibody Fab fragment to Staphylococcus aureus alpha-toxin (LTM14 Fab) as therapy for S. aureus keratitis. A single topical drop of the LTM14 Fab antibody to alpha-toxin alone, or in 0.006% benzalkonium chloride (BAK), was applied every 30 min to S. aureus-infected rabbit corneas from 9 to 14 hours post-infection. Erosions and pathology were measured at 15 h post-infection. LTM14 Fab with BAK limited corneal erosions better than LTM14 Fab alone (p = 0.036), and both limited erosions compared to untreated eyes (p ≤ 0.0001). Overall pathology was similar in all groups (p ≥ 0.070), but iritis and chemosis were reduced by treatment (p ≤ 0.036). The high-affinity human monoclonal Fab fragment antibody (LTM14 Fab) to S. aureus alpha-toxin was effective in reducing corneal damage during S. aureus keratitis.

Abstract. The main aim of this study was to design and develop hybrid dryer in which heat sources are coming from coffee husks furnace and solar collectors used for coffee beans drying. We also tested its performance and calculated the energy consumption produced and total costs required to perform coffee beans drying. The study consisted of three stages; (1 structural and functional design of drying chamber, furnace and solar collector, (2 dryer construction and development, (3 functional test. The overall results of this study showed that solar collector was effectively working properly during the ten days drying. Yet, this developed dryer is still heavily influenced by the weather, and thus the use of biomass as an energy supplement is needed. The average air temperature produced by the dryer ranges between 36.2 oC to 48.6 oC, while the relative humidity (RH ranging from 43.6% -72.6%.

The annual title survey shows for 1995 that Dutch households consumed more than 120 million m 3 of natural gas, which is higher than in 1994. The average consumption per dwelling slightly decreased. Gas consumption for cooking and hot water remained the same. The slight decrease in the average consumption is caused by space heating. The decrease seemed to halt last year, but still continues for the time being. However, it is too early to refer to it as a trend. 3 figs., 7 tabs

Invasive fungal infections are an important cause of morbidity and mortality in immunodeficient children. Amphotericin B is an important therapeutic agent for the treatment of invasive fungal infections but is associated with significant toxicities and high acquisition costs. The purpose of this study was to evaluate physician adherence to a local guideline for the use of lipid-based amphotericin B. The study was approved through Pharmacology & Therapeutics (P&T) committee activities. A retrospective drug utilization review (DUR) was conducted. All orders written between January 1, 2003, and December 31, 2004, were reviewed. Demographic and descriptive clinical data were collected as well as variables related to the drug order process. Conformity rates were calculated for the primary objective criteria (authorized prescribers - infectious disease members; recommended drug of choice-Abelcet; accepted indications; and presence of underlying conditions). A total of 109 orders for 70 patients were reviewed by a single research assistant for a 2-year period. Global conformity rate for all four criteria was calculated at 7.3%. Non-conformity was mostly associated with the absence of underlying conditions (e.g., prerenal insufficiency or presence of nephrotoxicity due to amphotericin B desoxycholate) in 84.5% of the cases. Infusionrelated adverse drug reactions partly explained a switch to a non-formulary lipid-based amphotericin B product. External factors (newly published results since the adoption of the guideline and continuous marketing practices) and internal factors (availability of non-formulary process, inefficient DUR process) could have contributed to non-adherence to a local guideline. This study shows low adherence to P&T committee drug guidelines on lipid-based amphotericin B. Continuous and efficient DUR processes should be in place to monitor drug guideline adherence.

In microbial processes for production of proteins, biomass and nitrogen-containing commodity chemicals, ATP requirements for nitrogen assimilation affect product yields on the energy producing substrate. In Saccharomyces cerevisiae, a current host for heterologous protein production and potential platform for production of nitrogen-containing chemicals, uptake and assimilation of ammonium requires 1 ATP per incorporated NH3. Urea assimilation by this yeast is more energy efficient but still requires 0.5 ATP per NH3 produced. To decrease ATP costs for nitrogen assimilation, the S. cerevisiae gene encoding ATP-dependent urease (DUR1,2) was replaced by a Schizosaccharomyces pombe gene encoding ATP-independent urease (ure2), along with its accessory genes ureD, ureF and ureG. Since S. pombe ure2 is a Ni(2+)-dependent enzyme and Saccharomyces cerevisiae does not express native Ni(2+)-dependent enzymes, the S. pombe high-affinity nickel-transporter gene (nic1) was also expressed. Expression of the S. pombe genes into dur1,2Δ S. cerevisiae yielded an in vitro ATP-independent urease activity of 0.44±0.01 µmol min(-1) mg protein(-1) and restored growth on urea as sole nitrogen source. Functional expression of the Nic1 transporter was essential for growth on urea at low Ni(2+) concentrations. The maximum specific growth rates of the engineered strain on urea and ammonium were lower than those of a DUR1,2 reference strain. In glucose-limited chemostat cultures with urea as nitrogen source, the engineered strain exhibited an increased release of ammonia and reduced nitrogen content of the biomass. Our results indicate a new strategy for improving yeast-based production of nitrogen-containing chemicals and demonstrate that Ni(2+)-dependent enzymes can be functionally expressed in S. cerevisiae.

The cellulose binding elicitor lectin (CBEL) of the genus Phytophthora induces necrosis and immune responses in several plant species, including Arabidopsis thaliana. However, the role of CBEL-induced responses in the outcome of the interaction is still unclear. This study shows that some of CBEL-induced defence responses, but not necrosis, required the receptor-like kinase BAK1, a general regulator of basal immunity in Arabidopsis, and the production of a reactive oxygen burst mediated by respiratory burst oxidases homologues (RBOH). Screening of a core collection of 48 Arabidopsis ecotypes using CBEL uncovered a large variability in CBEL-induced necrotic responses. Analysis of non-responsive CBEL lines Ws-4, Oy-0, and Bla-1 revealed that Ws-4 and Oy-0 were also impaired in the production of the oxidative burst and expression of defence genes, whereas Bla-1 was partially affected in these responses. Infection tests using two Phytophthora parasitica strains, Pp310 and Ppn0, virulent and avirulent, respectively, on the Col-0 line showed that BAK1 and RBOH mutants were susceptible to Ppn0, suggesting that some immune responses controlled by these genes, but not CBEL-induced cell death, are required for Phytophthora parasitica resistance. However, Ws-4, Oy-0, and Bla-1 lines were not affected in Ppn0 resistance, showing that natural variability in CBEL responsiveness is not correlated to Phytophthora susceptibility. Overall, the results uncover a BAK1- and RBOH-dependent CBEL-triggered immunity essential for Phytophthora resistance and suggest that natural quantitative variation of basal immunity triggered by conserved general elicitors such as CBEL does not correlate to Phytophthora susceptibility.

25 Years of Self-organized Criticality: Concepts and Controversies
Watkins, Nicholas W.; Pruessner, Gunnar; Chapman, Sandra C.; Crosby, Norma B.; Jensen, Henrik J.
2016-01-01
Introduced by the late Per Bak and his colleagues, self-organized criticality (SOC) has been one of the most stimulating concepts to come out of statistical mechanics and condensed matter theory in the last few decades, and has played a significant role in the development of complexity science. SOC, and more generally fractals and power laws, have attracted much comment, ranging from the very positive to the polemical. The other papers (Aschwanden et al. in Space Sci. Rev., 2014, this issue; McAteer et al. in Space Sci. Rev., 2015, this issue; Sharma et al. in Space Sci. Rev. 2015, in preparation) in this special issue showcase the considerable body of observations in solar, magnetospheric and fusion plasma inspired by the SOC idea, and expose the fertile role the new paradigm has played in approaches to modeling and understanding multiscale plasma instabilities. This very broad impact, and the necessary process of adapting a scientific hypothesis to the conditions of a given physical system, has meant that SOC as studied in these fields has sometimes differed significantly from the definition originally given by its creators. In Bak's own field of theoretical physics there are significant observational and theoretical open questions, even 25 years on (Pruessner 2012). One aim of the present review is to address the dichotomy between the great reception SOC has received in some areas, and its shortcomings, as they became manifest in the controversies it triggered. Our article tries to clear up what we think are misunderstandings of SOC in fields more remote from its origins in statistical mechanics, condensed matter and dynamical systems by revisiting Bak, Tang and Wiesenfeld's original papers.

Humiliation and love. Villaggio, Benigni and the cultural politics of emotions
Directory of Open Access Journals (Sweden)
Francesco Ricatti
2014-12-01
Full Text Available Umiliazione e amore: Villaggio, Benigni e la politica culturale delle emozioniLa forte dicotomia emotiva fra eroismo e codardia ha svolto un ruolo importante nella costruzione ed evoluzione dell’identità nazionale italiana. Questo articolo considera le opere più influenti di Paolo Villaggio e Roberto Benigni, e il loro ruolo nello sviluppo di una alternativa emotiva a tale dicotomia. I loro film si concentrano principalmente su una singola emozione: l’umiliazione nel caso di Villaggio, e l’amore nel caso di Benigni. È attraverso questa attenzione ad una singola emozione che questi autori e interpreti sono riusciti a costruire dei personaggi che, pur tipicamente italiani, non possono essere facilmente ricondotti né alla categoria dell’eroe né a quella del codardo. L’articolo sostiene l’importanza politica di questa alternativa emotiva, e nota come il suo progressivo indebolimento sia coinciso con l’incapacità della sinistra italiana di elaborare una risposta efficace alle politiche fortemente emotive di Berlusconi. L’articolo dimostra l’importanza di studiare i complessi rapporti fra comicità, emozioni e politica nella storia culturale e politica italiana.

Humour, halters and humiliation: wife-sale as theatre and self-divorce
Vaessen, Rachel
2006-01-01
During the eighteenth and nineteenth centuries a number of England's regional newspapers published descriptions of a popular rural custom known as wife-sale. This event incorporated the symbolism of a livestock auction with a public declaration by a husband and wife to part ways. While previous studies have focused on wife-sale as a mode of self-divorce, the present work explores the meaning behind the symbols and rituals of wife-sale within the context of English popular culture.

Humiliated silence: multiculturalism, blame and the trope of ‘moving on’
Directory of Open Access Journals (Sweden)
Emma Waterton
2010-11-01
Full Text Available The issue of slavery has received wide media attention in response to the bicentenary of the abolition of the slave trade. Simultaneously, issues of multiculturalism and social exclusion have also been subject to tense debate. This paper aims to examine the rhetorical resources drawn upon at the juncture of these two areas of debate, particularly in terms of how the ‘slave trade’ and its abolition is understood, constructed and remembered. In order to examine how these issues are manifest, the paper utilizes critical discursive methodologies, which are applied to institutional and ‘official’ responses to the bicentenary of 1807. This data will be examined in terms of the discursive strategies drawn upon to actively absolve current generations from challenging the latent issues of power operative within modern British society.

Full Text Available Bu çalışmada Köse deresi yağış havzasında toprağı oluşturan faktörlerin hidro-fiziksel toprak özellikleri üzerindeki etkileri araştırılmıştır. Köse deresi yağış havzasının bu amaçla seçilmesinin nedeni, bu yağış havzasının çıkış yerinde sulama amaçlı bir su depolama tesisinin yapılmakta oluşudur. Bu amaçla yetişme ortamı koşulları olarak da ifade edilebilen toprak oluşum faktörlerinden genel iklim özellikleri, ana materyal ve eğim sabit; yükselti kademesi, bakı, arazi kullanım şekilleri ve derinlik kademeleri değişken faktörler olarak alınmıştır. Bu çalışmada, sabit alınan ana materyal üzerinde 1700-1800 m, 1800-1900 m ve 1900-2000 m yükselti kademelerinde orman, tarım ve mera alanlarının bulunması, 0-20 cm ve 20-40 cm derinlik kademelerinin üst ve alt toprak özelliklerinin karşılaştırılmasına elverişli olması çalışma yönteminin oluşturulmasında etkili olmuştur. Araştırmada incelenen hidro-fiziksel toprak özellikleri; derinlik kademeleri başta olmak üzere, bakı ve yükselti kademeleri etkisinde değişime uğrarken, bu özellikler arazi kullanım şekillerinden daha az etkilenmişlerdir. Bakı, yükselti ve derinlik kademelerinin hidro-fiziksel toprak özelliklerini etkilemeleri, genel iklim koşullarıyla ilişkilendirilebilir. Bu çalışmada, dispersiyon oranı da incelenmiştir. Bu oranda değişime neden olan etkenlerin bakı ve yükselti kademeleri oldukları belirlenmiştir. Dispersiyon oranı sonuçları araştırma alanı topraklarının erozyona yatkın olduklarını göstermiştir.

The Anatomy Lecture Then and Now: A Foucauldian Analysis
Friesen, Norm; Roth, Wolff-Michael
2014-01-01
Although there are many points of continuity, there are also a number of changes in the pedagogical form of the anatomy lecture over the longue durée, over centuries of epistemic change, rather than over years or decades. The article begins with an analysis of the physical and technical arrangements of the early modern anatomy lecture, showing how…

In this study, we introduce the construct of the suicidal narrative, a hypothetical personal narrative linked to imminent suicide, and explore its relationship to near-term suicidal risk and the suicide crisis syndrome (SCS). Psychiatric outpatients (N = 289) were administered the Columbia Suicide-Severity Rating Scale (C-SSRS), Suicide Crisis Inventory (SCI), and Suicide Narrative Inventory (SNI), a novel instrument combining the documented risk factors of Thwarted Belongingness, Perceived Burdensomeness, Humiliation, Social Defeat, Goal Disengagement, and Goal Reengagement. Dimensional measures of past month, lifetime, and past suicidal phenomena, incorporating ideation and behavior, were calculated from the C-SSRS. Structural equation modeling was used to explore the interaction among variables. Factor analysis of the SNI yielded two orthogonal factors, termed Interpersonal and Goal Orientation. The former factor was comprised of Perceived Burdensomeness, Social Defeat, Humiliation, and Thwarted Belongingness, the latter of Goal Disengagement and Goal Reengagement. The Interpersonal factor correlated with both SCS severity and suicidal phenomena in each time frame and the Goal Orientation factor with no other variable. As hypothesized, the proposed model was significant for the past month only. Our findings support the construct of the suicidal narrative and its function as a near-term suicidal risk factor. © 2018 The American Association of Suicidology.

Distributive value judgments based on the 'origins' of economic inequalities (e.g. circumstances and responsible choices) are increasingly evoked to argue that 'the worst form of inequality is to try to make unequal things equal'. However, one may reasonably agree that distributive value judgments should also account for the 'consequences' of economic inequalities in such a way as to (i) improve economic efficiency and (ii) prevent from subordination, exploitation and humiliation. In this way...

Full Text Available Bri1-associated kinase 1 (BAK1-interacting receptor-like kinase (BIR proteins have been shown to play important roles in regulating growth and development, pathogen associated molecular pattern (PAMP-triggered immunity (PTI responses, and cell death in the model plant, Arabidopsis thaliana. We identified four BIR family members in tomato (Solanum lycopersicum, including SlBIR3, an ortholog of AtBIR3 from A. thaliana. SlBIR3 is predicted to encode a membrane localized non-arginine-aspartate (non-RD kinase that, based on protein sequence, does not have autophosphorylation activity but that can be phosphorylated in vivo. We established that SlBIR3 interacts with SlBAK1 and AtBAK1 using yeast two-hybrid assays and co-immunoprecipitation and maltose-binding protein pull down assays. We observed that SlBIR3 overexpression in tomato (cv. micro-tom and A. thaliana has weak effect on growth and development through brassinosteroid (BR signaling. SlBIR3 overexpression in A. thaliana suppressed flg22-induced defense responses, but did not affect infection with the bacterial pathogen Pseudomonas syringae (PstDC3000. This result was confirmed using virus-induced gene silencing (VIGS in tomato in conjunction with PstDC3000 infection. Overexpression of SlBIR3 in tomato (cv. micro-tom and A. thaliana resulted in enhanced susceptibility to the necrotrophic fungus Botrytis cinerea. In addition, co-silencing SlBIR3 with SlSERK3A or SlSERK3B using VIGS and the tobacco rattle virus (TRV-RNA2 vector containing fragments of both the SlSERK3 and SlBIR3 genes induced spontaneous cell death, indicating a cooperation between the two proteins in this process. In conclusion, our study revealed that SlBIR3 is the ortholog of AtBIR3 and that it participates in BR, PTI, and cell death signaling pathways.

Full Text Available Aim. The purpose of this study is to evaluate and compare the efficacy of 4 prostaglandin analogues (PGAs and to determine the incidence of ocular surface disease in newly diagnosed, primary open-angle glaucoma (POAG patients started on one of those 4 PGAs: bimatoprost (benzalkonium chloride, BAK, 0.3 mg/mL, latanoprost (BAK 0.2 mg/mL, travoprost (polyquad, and tafluprost (BAK-free. Patients and Methods. In this single-center, open-label trial, 32 patients newly diagnosed with POAG were randomly started on one of the four PGAs. All patients underwent a complete ophthalmological exam at presentation and at 1, 3, and 6 months of follow-up. Dry eye disease (DED was assessed using the original Ocular Surface Disease Index (OSDI questionnaire, in order to evaluate the impact of the drops on the quality of life of patients. Results. The mean age was 60.06 years ± 11.76. All four drugs equally and significantly reduced the intraocular pressure (IOP with respect to the baseline IOP. There was a trend for a slightly greater reduction of IOP with bimatoprost, but the difference was not found to be statistically significant when compared to other PGAs. OSDI scores were significantly superior for travoprost (10.68 ± 5.73 compared to the other three drugs (p<0.05. Latanoprost caused the most significant eyelash growth and iris discoloration. Conjunctival hyperemia and superficial keratitis occurrence were similar in the four groups. Conclusion. All prostaglandin analogues equally and significantly reduce the IOP in patients with POAG. According to the results of the OSDI score, latanoprost seems to be the least tolerated among the four drugs.

To assess the effect of SofZia-preserved travoprost on ocular surface conditions in comparison with benzalkonium chloride (BAK)-preserved latanoprost. A prospective randomized multicentre single-masked comparative study. Patients with open-angle glaucoma or ocular hypertension who had been treated with BAK-preserved latanoprost 0.005% (Xalatan(®) ) monotherapy for at least 3 months. Patients were enrolled at 23 facilities. Patients were randomly divided into the X-X group, continuous use of Xalatan(®) , or the X-T group, switching from Xalatan(®) to SofZia-preserved travoprost 0.004% (TravatanZ(®) ), and followed for 3 months. The superficial punctate keratopathy (SPK), conjunctival epitheliopathy, hyperaemia, tear break-up time (TBUT) and intraocular pressure (IOP) were examined for each patient in a masked manner. Changes in the frequency of keratoconjunctival epitheliopathy were evaluated 3 months after study initiation. Intra- and intergroup comparisons of changes in SPK, conjunctival epitheliopathy, hyperaemia, TBUT and IOP were also carried out. Two hundred twenty patients participated and 215 completed the 3-month study. The frequency of keratoconjunctival epitheliopathy significantly decreased in the X-T group (p = 0.036) and the intergroup difference was also significant (p = 0.001). SPK scores and TBUT were significantly improved in the X-T group (p = 0.034, 0.049), also with significant intergroup differences in the cornea excluding the inferior area and TBUT. There were no significant intergroup differences in changes of the hyperaemia scores and the IOP reduction. Switching to SofZia-preserved travoprost after BAK-preserved latanoprost resulted in a lower incidence of keratoconjunctival epitheliopathy, especially in the cornea, with no clinically relevant changes in hyperaemia and IOP. © 2012 The Authors.

The irreversible ERBB1/2/4 inhibitor, neratinib, down-regulates the expression of ERBB1/2/4 as well as the levels of MCL-1 and BCL-XL. Venetoclax (ABT199) is a BCL-2 inhibitor. At physiologic concentrations neratinib interacted in a synergistic fashion with venetoclax to kill HER2 + and TNBC mammary carcinoma cells. This was associated with the drug-combination: reducing the expression and phosphorylation of ERBB1/2/3; in an eIF2α-dependent fashion reducing the expression of MCL-1 and BCL-XL and increasing the expression of Beclin1 and ATG5; and increasing the activity of the ATM-AMPKα-ULK1 S317 pathway which was causal in the formation of toxic autophagosomes. Although knock down of BAX or BAK reduced drug combination lethality, knock down of BAX and BAK did not prevent the drug combination from increasing autophagosome and autolysosome formation. Knock down of ATM, AMPKα, Beclin1 or over-expression of activated mTOR prevented the induction of autophagy and in parallel suppressed tumor cell killing. Knock down of ATM, AMPKα, Beclin1 or cathepsin B prevented the drug-induced activation of BAX and BAK whereas knock down of BID was only partially inhibitory. A 3-day transient exposure of established estrogen-independent HER2 + BT474 mammary tumors to neratinib or venetoclax did not significantly alter tumor growth whereas exposure to [neratinib + venetoclax] caused a significant 7-day suppression of growth by day 19. The drug combination neither altered animal body mass nor behavior. We conclude that venetoclax enhances neratinib lethality by facilitating toxic BH3 domain protein activation via autophagy which enhances the efficacy of neratinib to promote greater levels of cell killing.

Microtubule poisons and other anti-mitotic drugs induce tumor death but the molecular events linking mitotic arrest to cell death are still not fully understood. We have analyzed cell fate after mitotic arrest produced by the microtubule-destabilizing drug vincristine in a panel of human tumor cell lines showing different response to vincristine. In Jurkat, RPMI 8226 and HeLa cells, apoptosis was triggered shortly after vincristine-induced mitotic arrest. However, A549 cells, which express a great amount of Bcl-x{sub L} and undetectable amounts of Bak, underwent mitotic slippage prior to cell death. However, when Bcl-x{sub L} gene was silenced in A549 cells, vincristine induced apoptosis during mitotic arrest. Another different behavior was found in MiaPaca2 cells, where vincristine caused death by mitotic catastrophe that switched to apoptosis when cyclin B1 degradation was prevented by proteasome inhibition. Overexpression of Bcl-x{sub L} or silencing Bax and Bak expression delayed the onset of apoptosis in Jurkat and RPMI 8226 cells, enabling mitotic slippage and endoreduplication. In HeLa cells, overexpression of Bcl-x{sub L} switched cell death from apoptosis to mitotic catastrophe. Mcl-1 offered limited protection to vincristine-induced cell death and Mcl-1 degradation was not essential for vincristine-induced death. All these results, taken together, indicate that the Bcl-x{sub L}/Bak ratio and the ability to degrade cyclin B1 determine cell fate after mitotic arrest in the different tumor cell types. Highlights: ► Vincristine induces cell death by apoptosis or mitotic catastrophe. ► Apoptosis-proficient cells die by apoptosis during mitosis upon vincristine treatment. ► p53wt apoptosis-deficient cells undergo apoptosis from a G1-like tetraploid state. ► p53mt apoptosis-deficient cells can survive and divide giving rise to 8N cells.

Full Text Available AbstractThe fungus Leptosphaeria maculans (L. maculans is the causal agent of blackleg disease of canola/oilseed rape (Brassica napus worldwide. We previously reported cloning of the B. napus blackleg resistance gene, LepR3, which encodes a receptor-like protein. LepR3 triggers localised cell death upon recognition of its cognate Avr protein, AvrLm1. Here, we exploited the Nicotiana benthamiana model plant to investigate the recognition mechanism of AvrLm1 by LepR3. Co-expression of the LepR3/AvrLm1 gene pair in N. benthamiana resulted in development of a hypersensitive response (HR. However, a truncated AvrLm1 lacking its indigenous signal peptide was compromised in its ability to induce LepR3-mediated HR, indicating that AvrLm1 is perceived by LepR3 extracellularly. Structure-function analysis of the AvrLm1 protein revealed that the C-terminal region of AvrLm1 was required for LepR3-mediated HR in N. benthamiana and for resistance to L. maculans in B. napus. LepR3 was shown to be physically interacting with the B. napus receptor like kinase, SOBIR1 (BnSOBIR1. Silencing of NbSOBIR1 or NbSERK3 (BAK1 compromised LepR3-AvrLm1-dependent HR in N. benthamiana, suggesting that LepR3-mediated resistance to L. maculans in B. napus requires SOBIR1 and BAK1/SERK3. Using this model system, we determined that BnSOBIR1 and SERK3/BAK1 are essential partners in the LepR3 signalling complex and were able to define the AvrLm1 effector domain.

The co-evolutionary dynamics of directed network of spin market agents
Horváth, Denis; Kuscsik, Zoltán; Gmitra, Martin
2006-09-01
The spin market model [S. Bornholdt, Int. J. Mod. Phys. C 12 (2001) 667] is generalized by employing co-evolutionary principles, where strategies of the interacting and competitive traders are represented by local and global couplings between the nodes of dynamic directed stochastic network. The co-evolutionary principles are applied in the frame of Bak-Sneppen self-organized dynamics [P. Bak, K. Sneppen, Phys. Rev. Lett. 71 (1993) 4083] that includes the processes of selection and extinction actuated by the local (node) fitness. The local fitness is related to orientation of spin agent with respect to the instant magnetization. The stationary regime is formed due to the interplay of self-organization and adaptivity effects. The fat tailed distributions of log-price returns are identified numerically. The non-trivial model consequence is the evidence of the long time market memory indicated by the power-law range of the autocorrelation function of volatility with exponent smaller than one. The simulations yield network topology with broad-scale node degree distribution characterized by the range of exponents 1.3social networks.

Latest news on Arabidopsis brassinosteroid perception and signaling
Directory of Open Access Journals (Sweden)
Klaus eHarter
2011-10-01
Full Text Available Brassinosteroids (BR are plant hormones regulating growth and development. In interaction with other hormones, they are involved in environmental cue responses. The standard BR response pathway model in Arabidopsis includes the perception of the hormone by the plasma membrane receptor BRASSINOSTEROID INSENSITIVE 1 (BRI1 and its hetero-oligomerisation with the co-receptor BRI1-ASSOCIATED RECEPTOR KINASE 1 (BAK1, followed by the activation of a signaling cascade finally resulting in the expression of BR-responsive genes. Recent findings have shed new light on the molecular mechanism of BR perception, which includes the hormone-induced formation of a platform in BRI1 extracellular domain for interaction with BAK1, and on very early events of signaling at the plasma membrane-cytoplasm interface. In addition, a fast BR response pathway that modifies the membrane potential and the expansion of the cell wall – both crucial processes preceding cell elongation growth – was identified. In this review, these latest findings are summarized and discussed against the background of the standard model of BRI1-dependent signaling.

Full Text Available Pompa hidram bekerja berdasarkan prinsip palu-air. Ketika aliran fluida dihentikan secara tiba-tiba, maka perubahan momentum massa fluida tersebut akan meningkatkan tekanan secara tiba-tiba pula. Peningkatan tekanan ini digunakan untuk mengangkat sebagian fluida tersebut ke tempat yang lebih tinggi. Untuk itu, penelitian ini berusaha untuk mengetahui besarnya head tekanan akibat palu-air pada instalasi pompa hidram dengan dan tanpa tabung udara. Parameter yang diamati adalah besarnya peningkatan tekanan pada pipa penghantar, badan pompa, leher pompa, pipa penyalur serta debit yang dihasilkan pada bak limbah dan bak penampung. Dari hasil penelitian didapatkan bahwa head tekanan balik di dalam pipa penghantar menurun dari 103,87 m tanpa menggunakan tabung udara menjadi 37,85 m dengan tabung udara. Selanjutnya, dalam pipa penyalur head tekanan akibat water hammer meningkat dari 0,29 m tanpa menggunakan tabung udara menjadi 2,9 m dengan menggunakan tabung udara. Sehingga pemasangan tabung udara dapat meningkatkan efisiensi pompa hidram secara signifikan dari 0.72 % tanpa tabung menjadi 19,45 % dengan tabung udara.

Interference Suppression Performance of Automotive UWB Radars Using Pseudo Random Sequences
Directory of Open Access Journals (Sweden)
I. Pasya
2015-12-01
Full Text Available Ultra wideband (UWB automotive radars have attracted attention from the viewpoint of reducing traffic accidents. The performance of automotive radars may be degraded by interference from nearby radars using the same frequency. In this study, a scenario where two cars pass each other on a road was considered. Considering the utilization of cross-polarization, the desired-to-undesired signal power ratio (DUR was found to vary approximately from -10 to 30 dB. Different pseudo random sequences were employed for spectrum spreading the different radar signals to mitigate the interference effects. This paper evaluates the interference suppression provided by maximum length sequence (MLS and Gold sequence (GS through numerical simulations of the radar’s performance in terms of probability of false alarm and probability of detection. It was found that MLS and GS yielded nearly the same performance when the DUR is -10 dB (worst case; for example when fixing the probability of false alarm to 0.0001, the probabilities of detection were 0.964 and 0.946 respectively. The GS are more advantageous than MLS due to larger number of different sequences having the same length in GS than in MLS.

Although the negative impact of parents’ excessive expectation on their children’s psychological well-being has long been pointed out, the quantitative research has rarely been done. This present study investigated the process of how parents’ excessive expectation related to adolescents’ depressive symptoms. The parenting practices that hurt adolescent feelings (e.g. “said that I humiliated him/her”) were put into the model as a mediator, and the effects of adolescent’s gender, parents’ warmt...

School bullying consists of harassment behaviours in a school setting and is characterized by violence acts, mockery or even humiliations between students. More recently, with the development of new technologies, our society has seen the cyber-bullying born. This new type of harassment "on-line" comes and intersects the harassment at school. After the description of a clinical situation, we describe the impact of this phenomenon on the different actors concerned, the lines for prevention and for appropriate support.

A STUDY ON CORPORAL PUNISHMENT IN SCHOOLS AT SIVAKASI
R. Kalaivani
2017-01-01
Corporal punishment has been classified as an act of violence and abuse on children. Strictly defined ‘corporal punishment’ is the infliction of pain intended to change a person’s behaviour or to punish them. Though it mainly refers to physical pain either through hitting or forcing the child to sit /stand in uncomfortable positions; an evolving definition also includes within its ambit wrongful confinement, verbal insults, threats and humiliation, which are used with impunity and in utter di...

Psychosocial and sexual aspects of female circumcision
S. Abdel-Azim
2013-01-01
Sexual behavior is a result of interaction of biology and psychology. Sexual excitement of the female can be triggered by stimulation of erotogenic areas; part of which is the clitoris. Female circumcision is done to minimize sexual desire and to preserve virginity. This procedure can lead to psychological trauma to the child; with anxiety, panic attacks and sense of humiliation. Cultural traditions and social pressures can affect as well the unexcised girl. Female circumcision can reduce fem...

Eating disorders - a submission or a resistance to social norms
Božič, Anja
2011-01-01
Eating disorders exist. They are present in our everyday society. In most cases we talk about them uneasily, reproachfully and ignorantly. We often link them to food and slenderness. Emotions, pain, unacceptance, denial, feeling of defeat, humiliation and inferiority are left behind. Only few are aware that people through waiver or overeating express distress since they want to become visible persons with needs and wishes for (self)respect and (self)acceptance. I placed eating disorders in so...

Notwithstanding the 19th century formal abolition of slavery as legal ownership of people, modern slavery and forced labour have not been consigned to the past. In fact, their existence is more widespread, and made more difficult to tackle due to the lack of formal, legal criteria. This article suggests that reference to the past, historical institutions reveals seven ‘badges of slavery’ that are helpful in identifying occurrences of modern slavery and forced labour. These are: humiliation, o...

¿Qué sigue luego de que una mujer terminara su relación con el último hombre que amaba? Eso, dicen ellas, depende de cuanto duró el romance o cómo sea la psiquis de cada amante. Lo cierto es que el escenario post convierte a algunas en depresivas, caletas, indiferentes y hasta amnésicas. ¿Qué te parece, varón?
