What\u27s \u27childless\u27 got to do with it?

Childlessness is increasing in Australia and has resulted in an upsurge of media commentary on the lives of childless women, This paper investigates the use of the label \u27childless\u27 in the Australian print media by drawing meaning and understanding from these representations within the context of pronatalist ideologies. Our analysis suggests that childless(ness) is used as an irrelevant descriptor and as a discreditable attribute, which fudher serves to perpetuate negative othering stereotypes of childless women. This is particularly exemplified through the representation of Australia\u27s Prime Minister Julia Gillard by the print media. This analysis highlights the continued positioning of women in regards to their reproductive status.<br /

Navigating the terrain of lived experiences: the value of lifeworld existentials for reflective analysis

In qualitative research we are often presented with a tension between having open and fluid interviews to support staying true to the lived experiences of participants and achieving a level of abstraction from the data in order to uncover the essential structures and meanings of that particular lived experience. A way of resolving this tension is through the application of theoretical frameworks. Van Manen&rsquo;s four lifeworld existentials offer a lens through which to explore and navigate disparate interview data and uncover the essences of lived experience, without imposing categories upon the data itself. Drawing on a study exploring the lived experiences of childless women, we explore the process and principles in operationalising the existentials and discuss the potential implications for analysis and findings. The article demonstrates how Van Manen&rsquo;s lifeworld existentials present us with a holistic and valuable method for reflective practice, in coming to understand lived experience

Blockade of collagen-induced arthritis post-onset by antibody to granulocyte-macrophage colony-stimulating factor (GM-CSF): requirement for GM-CSF in the effector phase of disease

There is mounting evidence for a role of the growth factor granulocyte-macrophage colony-stimulating factor (GM-CSF) in inflammatory disease, including arthritis. In the present study, we examined the effectiveness of treatment of collagen-induced arthritis (CIA) with a neutralizing mAb to GM-CSF. DBA/1 mice were immunized for the development of CIA and treated at different times, and with different doses, with neutralizing mAb to GM-CSF or isotype control mAb. Anti-GM-CSF mAb treatment prior to the onset of arthritis, at the time of antigen challenge, was effective at ameliorating the ensuing disease. Modulation of arthritis was seen predominantly as a reduction in overall disease severity, both in terms of the number of limbs affected per mouse and the clinical score of affected limbs. Importantly, anti-GM-CSF mAb treatment ameliorated existing disease, seen both as a reduction in the number of initially affected limbs progressing and lower numbers of additional limbs becoming affected. By histology, both inflammation and cartilage destruction were reduced in anti-GM-CSF-treated mice, and the levels of tumor necrosis factor-a and IL-1? were also reduced in joint tissue washouts of these mice. Neither humoral nor cellular immunity to type II collagen, however, was affected by anti-GM-CSF mAb treatment. These results suggest that the major effect of GM-CSF in CIA is on mediating the effector phase of the inflammatory reaction to type II collagen. The results also highlight the essential role of GM-CSF in the ongoing development of inflammation and arthritis in CIA, with possible therapeutic implications for rheumatoid arthritis

Use of whole plant Artemisia annua L. as an antimalarial therapy

Anti-malarial drugs are primary weapons for reducing Plasmodium transmission in human populations. Successful drugs have been highly efficacious and inexpensive to synthetically manufacture. Emergence of resistant parasites reduces the lifespan of each drug that is developed and deployed. Currently, the most effective anti-malarial is artemisinin (AN), which is extracted from the leaves of Artemisia annua. Because of its poor pharmacokinetic properties and prudent efforts to curtail emergence of resistance, AN is prescribed only in combination with other anti-malarials composing an Artemisinin Combination Therapy (ACT). Low yield in the plant and the added cost of secondary anti-malarials in the ACT, make AN in the developing world a costly treatment. Here we show that dried leaves of A. annua administered orally are more effective at killing malaria parasites than a comparable dose of purified drug in a rodent malaria model (P. chabaudi). A single dose of whole plant (WP) A. annua containing 24 mg/kg AN clears 99% of parasites, where a comparable dose of pure drug has half that effect. This is consistent with findings that blood levels of AN are 40 times greater in mice receiving WP versus those given pure drug. We hypothesize that in addition to increasing bioavailability of AN, administration of WP alone may constitute a combination therapy because it contains other anti-malarial compounds that have been shown to synergize with AN. Inexpensive, efficacious, and resilient treatment for malaria based upon WP A. annua that can be grown and processed locally would be an effective addition to the global effort to reduce malaria morbidity and mortality

Deficits in attention to emotional stimuli distinguish youth with severe mood dysregulation from youth with bipolar disorder.

Studying attention in the context of emotional stimuli may aid in differentiating pediatric bipolar disorder (BD) from severe mood dysregulation (SMD). SMD is characterized by chronic irritability, arousal, and hyper-reactivity; SMD youth frequently receive a BD diagnosis although they do not meet DSM-IV criteria for BD because they lack manic episodes. We compared 57 BD (14.4 +/- 2.9 years old, 56% male), 41 SMD (12.6 +/- 2.6 years old, 66% male), and 33 control subjects (13.7 +/- 2.5 years old, 52% male) using the Emotional Interrupt task, which examines how attention is impacted by positive, negative, or neutral distracters. We compared reaction time (RT) and accuracy and calculated attention interference scores by subtracting performance on neutral trials from emotional trials. Between-group analyses indicated that SMD subjects had significantly reduced attention interference from emotional distracters relative to BD and control subjects. Thus, attention in SMD youth was not modulated by emotional stimuli. This blunted response in SMD youth may contribute to their affective and behavioral dysregulation

Developing a Whole Plant Artemisia annua Antimalarial Therapeutic: pACT

The GRAS plant Artemisia annua L. produces the sesquiterpene lactone, artemisinin. The current therapy for malaria is artemisinin + an older drug: artemisinin combination therapy (ACT). In Plasmodium chabaudi-infected mice, dried leaves of A. annua are more potent than equal amounts of pure artemisinin and may also prevent artemisinin drug resistance from emerging. This whole plant therapy is pACT: plant-based artemisinin combination therapy. Pharmacokinetics in healthy and infected mice given either pure artemisinin or pACT is different and showed that \u3e 40 fold more artemisinin enters the blood when plant material is present; plant matrix enhanced bioavailability into serum. Dried leaves as capsules or tablets given to African malaria patients were also efficacious. Flavonoids, phenolic acids, monoterpenes and other artemisinic metabolites found in the plant have mild antimalarial activity. Some may synergize with artemisinin to enhance its efficacy. In simulated digestion studies the effects of cellulose and gelatin capsules, sucrose, 4 oils, and 3 staple grains (rice, corn, and millet) were studied to determine their effect on AN and flavonoid release into the liquid phase of the intestinal stage of digestion. Compared to pACT alone: sucrose and oil enhanced release of flavonoids by 100%, but artemisinin was unaffected; both capsule types, and corn and millet meal significantly reduced artemisinin release, but had no effect on flavonoids. From field trials in MA, it was estimated that \u3e 500,000 patients could be treated from plants grown on 1 ac of land. Analysis of 10 crops of the high artemisinin-producing WPI clone of A. annua grown under different field and lab conditions showed there was consistent production of artemisinin at about 1.4% DW. Together these results show how a simple herbal remedy could be used as an efficacious, inexpensive, controlled and sustainable orally delivered therapeutic for treating malaria and other artemisinin-susceptible diseases

Specificity of facial expression labeling deficits in childhood psychopathology

Background: We examined whether face-emotion labeling deficits are illness-specific or an epiphenomenon of generalized impairment in pediatric psychiatric disorders involving mood and behavioral dysregulation. Method: Two hundred fifty-two youths (7-18 years old) completed child and adult facial expression recognition subtests from the Diagnostic Analysis of Nonverbal Accuracy (DANVA) instrument. Forty-two participants had bipolar disorder (BD), 39 had severe mood dysregulation (SMD; i.e., chronic irritability, hyperarousal without manic episodes), 44 had anxiety and/or major depressive disorders (ANX/MDD), 35 had attention-deficit/hyperactivity and/or conduct disorder (ADHD/CD), and 92 were controls. Dependent measures were number of errors labeling happy, angry, sad, or fearful emotions. Results: BD patients made more errors than ANX/MDD, ADHD/CD, or controls when labeling all emotional expressions, whether those expressions were on the faces of children or adults. SMD also showed emotion-labeling deficits, in particular as compared to ANX/MDD patients and controls. Conclusions: Face-emotion labeling deficits differentiate BD and SMD patients from those with ANX/MDD or ADHD/CD and controls. The extent to which such deficits cause vs. result from emotional dysregulation requires further study

Stereotyping starlings are more 'pessimistic'.

Negative affect in humans and animals is known to cause individuals to interpret ambiguous stimuli pessimistically, a phenomenon termed 'cognitive bias'. Here, we used captive European starlings (Sturnus vulgaris) to test the hypothesis that a reduction in environmental conditions, from enriched to non-enriched cages, would engender negative affect, and hence 'pessimistic' biases. We also explored whether individual differences in stereotypic behaviour (repetitive somersaulting) predicted 'pessimism'. Eight birds were trained on a novel conditional discrimination task with differential rewards, in which background shade (light or dark) determined which of two covered dishes contained a food reward. The reward was small when the background was light, but large when the background was dark. We then presented background shades intermediate between those trained to assess the birds' bias to choose the dish associated with the smaller food reward (a 'pessimistic' judgement) when the discriminative stimulus was ambiguous. Contrary to predictions, changes in the level of cage enrichment had no effect on 'pessimism'. However, changes in the latency to choose and probability of expressing a choice suggested that birds learnt rapidly that trials with ambiguous stimuli were unreinforced. Individual differences in performance of stereotypies did predict 'pessimism'. Specifically, birds that somersaulted were more likely to choose the dish associated with the smaller food reward in the presence of the most ambiguous discriminative stimulus. We propose that somersaulting is part of a wider suite of behavioural traits indicative of a stress response to captive conditions that is symptomatic of a negative affective state
