Seeing is Not Stereotyping: The Functional Independence of Categorization and Stereotype Activation.

Social categorization has been viewed as necessarily resulting in stereotyping, yet extant research suggests the two processes are differentially sensitive to task manipulations. Here we simultaneously test the degree to which race perception and stereotyping are conditionally automatic. Participants performed a sequential priming task while either explicitly attending to the race of face primes or directing attention away from their semantic nature. We find a dissociation between the perceptual encoding of race and subsequent activation of associated stereotypes, with race perception occurring in both task conditions, but implicit stereotyping occurring only when attention is directed to the race of the face primes. These results support a clear conceptual distinction between categorization and stereotyping and show that the encoding of racial category need not result in stereotype activation.

Death of an Ex-Spouse: Lessons in Family Communication about Disenfranchised Grief.

The death of a loved one is an emotional-laden experience, and while grief and mourning rituals are less formal today in many communities, there remain some social norms for individuals to process loss. The death of an ex-family member, such as a former spouse, is more complicated and expectations for how to respond are fraught with uncertainty. While grief has been studied and is primarily understood as an individual cognitive process, scholars in sociology and communication are considering the ways in which grief and mourning are social and take place in dialogue with others. This manuscript explores Kenneth Doka's concept of disenfranchised grief, which is "grief that is experienced when loss cannot be openly acknowledged, socially sanctioned, or publicly mourned" through the author's experience of the death of her ex-husband. The narrative will recount how the author learned about her ex-husband's death (via text message), and will challenge definitions of family and family communication about death and grief, particularly the communication strategies used to cope with this unique type of loss.

Psychological approaches to behaviour for improving plaque control.

Data sourcesThe Cochrane Oral Health Groups Trial Register, Medline, Embase and PsycINFO.Study selectionRandomised controlled trials (RCTs), controlled clinical trials (CCTs), cohort studies or case-control studies were considered. Only studies in patients aged 18 or older with pre-existing periodontal disease and clearly stating a psychological model or theory had been used were included. Studies exploring smoking cessation were not included.Data extraction and synthesisAll data were collected by a single author using pre-decided parameters. The reviewers used the Cochrane criteria to assess risk of bias in clinical trials and the Newcastle Ottawa Scale for observational studies. Marked heterogeneity from the wide variety of psychological approaches used in the studies prevented meta-analysis.ResultsFifteen papers relating to 14 different studies were included from an initial 722 articles identified. This included three cohort studies, ten RCTs and a before/after study. A total of 1,106 patients were included across the studies. Of the 19 psychological models included in the initial search, seven were shown to have some form of impact on oral hygiene motivation, demonstrated by observed behavioural and clinical outcomes.ConclusionsThe authors concluded that, in adult patients with pre-existing periodontal disease, understanding of the seriousness of periodontal disease and the benefits of behavioural change resulted in improved adherence to oral hygiene instructions. They concluded that goal-setting, self-monitoring and indeed planning can be useful in improving oral health-related behaviours.

Preventing perioperative bleeding in patients with inherited bleeding disorders.

Data sourcesCochrane Cystic Fibrosis and Genetic Disorders Group's Coagulopathies Trials Register, a regularly updated database informed by trials identified within electronic databases including MEDLINE. Further defined searches were undertaken in PubMed, Embase, The Cochrane Library, ClinicalTrials.gov and WHO International Clinical Trials Registry Platform. Additional hand searching of relevant journals and books of conference proceedings was undertaken.Study selectionRandomised and quasi-randomised controlled trials in people of all ages with haemophilia or VWD undergoing oral or dental procedures using antifibrinolytic agents (tranexamic acid (TXA) or epsilon aminocaproic acid (EACA)) to prevent perioperative bleeding compared to no intervention with or without placebo.Data extraction and synthesisTwo authors independently assessed identified publications for inclusion based on defined selection criteria. The two authors performed data extraction and risk of bias assessments using standardised forms and the Cochrane risk of bias tools. A third author, deemed to have particular subject expertise, verified eligibility of inclusion.ResultsOne randomised, double-blinded placebo controlled trial and one quasi-randomised trial were included. A total of 59 participants with haemophilia undergoing dental extraction were involved. Both trials evidenced a notable reduction in post-operative bleeding following dental extraction when either TXA or EACA were used, in addition to routine preoperative factor replacement, when compared to placebo. The number of post-operative bleeds, amount of blood loss and the need for additional clotting factors were reduced in the groups receiving antifibrinolytic therapy. No eligible trials in people with VWD were identified.ConclusionsLow quality evidence exists to support the use of adjuvant antifibrinolytic therapy to reduce perioperative bleeding in patients with haemophilia undergoing dental extraction. The limited number of trials identified (N=2), minimal sample size (N=28, N=31) and historic nature of the studies, originating from the 1970s, in addition to study heterogeneity and subsequent selection bias results in a low quality evidence grade for recommending adjuvant antifibrinolytic therapy. There is no clear indication to alter current practice utilising antifibrinolytic therapy to manage patients with haemophilia undergoing dental surgery in accordance with internationally accepted guidelines. However, further research with standardised study deigns would be welcomed in order to enhance the evidence base in the management of people with haemophilia and VWD.

Development of a Miniature Mass Spectrometer and an Automated Detector for Sampling Explosive Materials.

The development of a robust ionization source using the counter-flow APCI, miniature mass spectrometer, and an automated sampling system for detecting explosives are described. These development efforts using mass spectrometry were made in order to improve the efficiencies of on-site detection in areas such as security, environmental, and industrial applications. A development team, including the author, has struggled for nearly 20 years to enhance the robustness and reduce the size of mass spectrometers to meet the requirements needed for on-site applications. This article focuses on the recent results related to the detection of explosive materials where automated particle sampling using a cyclone concentrator permitted the inspection time to be successfully reduced to 3 s.

Biomaterials innovation for next generation ex vivo immune tissue engineering.

Primary and secondary lymphoid organs are tissues that facilitate differentiation of B and T cells, leading to the induction of adaptive immune responses. These organs are present in the body from birth and are also recognized as locations where self-reactive B and T cells can be eliminated during the natural selection process. Many insights into the mechanisms that control the process of immune cell development and maturation in response to infection come from the analysis of various gene-deficient mice that lack some or all hallmark features of lymphoid tissues. The complexity of such animal models limits our ability to modulate the parameters that control the process of immune cell development, differentiation, and immunomodulation. Engineering functional, living immune tissues using biomaterials can grant researchers the ability to reproduce immunological events with tunable parameters for more rapid development of immunotherapeutics, cell-based therapy, and enhancing our understanding of fundamental biology as well as improving efforts in regenerative medicine. Here the author provides his review and perspective on the bioengineering of primary and secondary lymphoid tissues, and biomaterials innovation needed for the construction of these immune organs in tissue culture plates and on-chip.

A Specific Mixture of Nutrients Suppresses Ovarian Cancer A-2780 Tumor Incidence, Growth, and Metastasis to Lungs.

Ovarian cancer is the deadliest gynecological malignancy in women, and fifth leading cause of death. Despite advances made in chemotherapy and surgery, the average time of clinical remission is approximately 2 years and the 5-year survival rate is 45%. Thus, there is an urgent need for the development of a novel therapeutic approach to ovarian cancer treatment. We investigated the effect of a specific nutrient mixture (EPQ) containing ascorbic acid, lysine, proline, green tea extract, and quercetin on human ovarian cancer cell A-2780 in vivo and in vitro. Athymic female nude mice (n = 12) were all inoculated intraperitoneally (IP) with 2 × 10⁶ cells in 0.1 mL of phosphate buffered saline (PBS) and randomly divided into two groups. Upon injection, the Control group (n = 6) was fed a regular diet and the EPQ group (n = 6) a regular diet supplemented with 0.5% EPQ. Four weeks later, the mice were sacrificed and tumors that developed in the ovary were excised, weighed, and processed for histology. Lungs were inspected for metastasis. In vitro, A-2780 cells were cultured in Dulbecco modified Eagle medium supplemented with 10% FBS and antibiotics. At near confluence, cells were treated with EPQ in triplicate at concentrations between 0 and 1000 μg/mL. Cell proliferation was measured via MTT assay, MMP-9 secretion via gelatinase zymography, invasion through Matrigel and morphology via hematoxylin and eosin (H & E) staining. All Control mice developed large ovarian tumors, whereas 5 out of 6 mice in the EPQ group developed no tumors, and one, a small tumor. Control mice also showed lung metastasis in 6 out of 6 mice, while no lung metastasis was evident in EPQ mice. Zymography demonstrated only MMP-9 expression, which EPQ inhibited in a dose-dependent fashion, with virtual total block at 250 μg/mL concentration. EPQ significantly inhibited invasion through Matrigel with total block at 250 μg/mL concentration. MTT showed dose-dependent inhibition of cell proliferation with EPQ, and H & E staining showed no morphological changes below 500 μg/mL EPQ. These results suggest that EPQ has therapeutic potential in the treatment of ovarian cancer by significantly suppressing ovarian tumor incidence and growth and lung metastasis, and by inhibiting MMP-9 secretion and invasion of A-2780 ovarian cancer cells.

Control of the Bradysia odoriphaga (Diptera: Sciaridae) With Allyl Isothiocyanate Under Field and Greenhouse Conditions.

The botanical compound allyl isothiocyanate (AITC) is toxic to many microorganisms and insects. The aim of this study was to assess the effects of AITC on the Bradysia odoriphaga (Diptera: Sciaridae), as well as the seeds and seedlings of Chinese chive. AITC was toxic to all four stages of B. odoriphaga. The adult was significantly more sensitive (LC50 = 7.43 µl liter-1) to AITC than the other three stages, which had no difference in sensitivity to the chemical. The control efficacy of AITC against B. odoriphaga was much better in the greenhouse than that in the field. Also, there was higher seedling survival in the greenhouse compared with that in the field. In the absence of B. odoriphaga, seed germination and seedling growth of Chinese chive were inhibited by 16 µl liter-1 of AITC, and significant inhibition occurred under high dose of AITC. The results indicate that AITC could be used to control B. odoriphaga in Chinese chive fields.

Efficacy of Insect Growth Regulators and Diamide Insecticides for Control of Stem Borers (Lepidoptera: Crambidae) in Sugarcane.

Field experiments assessed control of the stem borers, Diatraea saccharalis (F.) and Eoreuma loftini (Dyar), in sugarcane (Saccharum spp.) with selected insect growth regulators and diamide insecticides. Tebufenozide, novaluron, chlorantraniliprole, and flubendiamide were evaluated for D. saccharalis control in four field experiments in Louisiana between 2009 and 2014. Aerial application of the same insecticides was evaluated for control of E. loftini in commercial sugarcane fields in southern Texas in 2012 and 2015. Stalk injury from D. saccharalis in nontreated plots ranged from 7.4-28.1% bored internodes across the four experiments. All insecticides reduced D. saccharalis injury compared with nontreated plots (39.1-99.4% reduction). Better control was achieved with novaluron, flubendiamide, and chlorantraniliprole than with tebufenozide. Pheromone trap-assisted scouting for E. loftini in Texas sugarcane helped to time insecticide applications. Reduced E. loftini injury was observed in diamide-treated plots (3.6-4.7% bored internodes) compared with nontreated controls (13.1%), but not in novaluron- (6.0%) or tebufenozide-treated (8.3%) plots in the 2012 experiment. Significant E. loftini injury was present prior to the aerial insecticide application in 2015, and differences in overall injury were not detected among treatments. However, chlorantraniliprole reduced injury to the top portion of sugarcane stalks. None of the insecticides improved sugar yields in 2012 or 2015. Results suggest insect growth regulators and diamide insecticides fit well in D. saccharalis management programs in Louisiana sugarcane. These chemistries also have potential to improve control of E. loftini, but more research into application strategies is needed to achieve consistent efficacy.

Influence of Abiotic Factors on Flight Initiation by Asian Citrus Psyllid (Hemiptera: Liviidae).

Predicting the emergence and arrival of insect pests is paramount for integrated pest management. To achieve this goal, it is important to understand how abiotic factors influence pest dispersal behavior. We investigated the effects of abiotic conditions on flight initiation by the Asian citrus psyllid, Diaphorina citri Kuwayama. We first explored the effect of barometric pressure changes on flight initiation. We used a custom-made barometric chamber and observed the activity of D. citri as measured by the number of psyllids captured on yellow cardboard panels coated with adhesive. We found that psyllid flight initiation changed in response to variations in barometric pressure rather than to differences in stable pressures. Diaphorina citri were equally active at 1,009 mbar and 1,022 mbar. However, D. citri dispersed more as barometric pressure increased, and less when barometric pressure decreased. In a subsequent experiment, we manipulated temperature and relative humidity and observed how D. citri dispersed between citrus plants. Psyllids dispersal increased linearly with temperature. Changes in humidity did not affect dispersal of D. citri. Less than 1% of psyllids dispersed at 15 °C, compared with 7.7% at 21 °C and 27% at 25 °C. The minimal threshold for D. citri to initiate flight is estimated to be 16.5 °C. Collectively, our results provide an initial step toward developing predictive models of D. citri movement as influenced by abiotic factors.

Insecticide Susceptibility in Asian Honey Bees (Apis cerana (Hymenoptera: Apidae)) and Implications for Wild Honey Bees in Asia.

To conserve local biodiversity and ensure the provision of pollination services, it is essential to understand the impact of pesticides on wild honey bees. Most studies that have investigated the effects of pesticides on honey bees have focused on the European honey bee (Apis mellifera (Hymenoptera: Apidae)), which is commonly domesticated worldwide. However, the Asian honey bee (Apis cerana) is widely distributed throughout Asia, and toxicity data are lacking for this species. This study aimed to fill this important knowledge gap. In this study, we determined the acute contact toxicity in A. cerana to various pesticides, including neonicotinoids, fipronil, organophosphorus, synthetic pyrethroids, carbamate, and anthranilic diamide. Based on the test duration of 48 h of contact LD50 tests, A. cerana was most sensitive to dinotefuran (0.0014 μg/bee), followed by thiamethoxam (0.0024 μg/bee) and fipronil (0.0025 μg/bee). Dinotefuran is used extensively in Asia, thereby potentially creating a substantial hazard. More generally, A. cerana was approximately one order of magnitude more sensitive than was A. mellifera to most of the pesticides evaluated. The results of our study suggest that neonicotinoid pesticides should not be considered as a single group that acts uniformly on all honey bees, and that more careful management strategies are required to conserve A. cerana populations than A. mellifera.
