Gender and Geoengineering

Geoengineering has been broadly and helpfully defined as “the intentional manipulation of the earth's climate to counteract anthropogenic climate change or its warming effects” (Corner and Pidgeon 2010, 26). Although there exists a rapidly growing literature on the ethics of geoengineering, very little has been written about its gender dimensions. The authors consider four contexts in which geoengineering appears to have important gender dimensions: (1) the demographics of those pushing the current agenda, (2) the overall vision of control it involves, (3) the design of the particular technologies, and (4) whom geoengineering will most affect and benefit. After detailing these four gender dimensions, we consider three ways in which the geoengineering discourse could be enriched if it became more sensitive to issues of gender. These include increasing the focus on the concrete other, recognizing the socially transformative potential of geoengineering technologies, and engaging in value‐sensitive design. Although ultimately remaining agnostic on the desirability of geoengineering, the paper brings gender considerations into a discussion from which they have been conspicuously absent.
The Buffering Effect of Social Support on Hypothalamic-Pituitary-Adrenal Axis Function During Pregnancy

Objective Recent studies suggest that effective social support during pregnancy may buffer adverse effects of maternal psychological distress on fetal development. The mechanisms whereby social support confers this protective advantage, however, remain to be clarified. The aim of this study was to assess whether individual differences in social support alter the covariation of psychological distress and cortisol during pregnancy. Methods Eighty-two pregnant women’s psychological distress and cortisol were prospectively assessed in all three trimesters using an ecological momentary assessment strategy. Appraisal of partner social support was assessed in each trimester via the Social Support Effectiveness questionnaire. Results In multilevel analysis, ambulatory assessments of psychological distress during pregnancy were associated with elevated cortisol levels (unstandardized &bgr; = .023, p < .001). Consistent with the stress-buffering hypothesis, social support moderated the association between psychological distress and cortisol (unstandardized &bgr; = −.001, p = .039), such that the covariation of psychological distress and cortisol increased with decreases in effective social support. The effect of social support for women with the most effective social support was a 50.4% reduction in the mean effect of distress on cortisol and a 2.3-fold increase in this effect for women with the least effective social support scores. Conclusions Pregnant women receiving inadequate social support secrete higher levels of cortisol in response to psychological distress as compared with women receiving effective social support. Social support during pregnancy may be beneficial because it decreases biological sensitivity to psychological distress, potentially shielding the fetus from the harmful effects of stress-related increases in cortisol.
Septic tenosynovitis in horses: 25 cases (1983-1989).

The medical records of 25 horses with septic tenosynovitis treated over 7 years (1983 to 1989) were reviewed to determine clinical features of the disease and response to treatment. The median age of horses with septic tenosynovitis was 5 years (range, 1 month to 21 years). Fourteen fore limbs and 11 hind limbs were affected. Sepsis was located in the sheath of the digital flexor tendons of 22 horses. Sepsis was located in the sheath of the extensor carpi radialis tendon (1 horse), sheath of the long digital extensor tendon (1 horse), or sheath of the common digital extensor tendon (1 horse) in the remaining horses. Nine horses received only medical treatment, using a combination of broad-spectrum parenterally administered antimicrobial drugs (8 of 9 horses), nonsteroidal anti-inflammatory drugs (8 of 9 horses), or irrigation of the wound (4 of 9 horses). Fourteen horses were treated surgically with either transection of the palmar/plantar annular ligament of the metacarpo/metatarsophalangeal joint (5 of 14 horses), lavage of the sheath after insertion of drains into the sheath (7 of 14 horses), or both (2 of 14 horses). All horses treated surgically were concurrently treated parenterally with broad-spectrum antimicrobial drugs and nonsteroidal anti-inflammatory drugs. Two horses with septic tenosynovitis were not treated and were euthanatized at the owners' request. Five horses were euthanatized before discharge from the hospital. Two horses (both treated medically) were lost to follow-up. Follow-up information was obtained for 18 horses, 6 to 55 months after discharge from the hospital. (ABSTRACT TRUNCATED AT 250 WORDS)
Immunological changes in cats with concurrent Toxoplasma gondii and feline immunodeficiency virus infections

To examine the immunological changes in cats concurrently infected with feline immunodeficiency virus (FIV) and Toxoplasma gondii, kittens (four per group) were inoculated with FIV, T. gondii, both agents, or no pathogens. Blood mononuclear cells and plasma were collected weekly for lymphocyte assays and serology. At week 14, spleen and lymph node cells were used for lymphocyte assays; brains and mesenteric lymph nodes were used for isolation of T. gondii. More T. gondii organisms were present in tissues of the dually infected cats than in tissues of cats with toxoplasmosis alone. Two dually infected cats and one cat infected with T. gondii developed chorioretinitis. Spleen, lymph node, and blood mononuclear cells from dually infected cats had the greatest reduction in mitogenic responses. By week 3, cats infected with FIV underwent a decrease in the number of CD4 cells that was not changed by concurrent T. gondii infection; the number of CD8 cells increased only in cats infected with T. gondii alone. For cats infected with T. gondii, the responses of lymphocytes to T. gondii antigen were not affected by FIV infection; the responses to FIV antigen were negligible in all groups. Overall, this study indicates that FIV infection favors T. gondii proliferation. Also, the establishment of toxoplasmosis may enhance FIV-induced immunodeficiency and is likely to cause a more rapid disease progression than that from infection with FIV alone.
Motor unit survival in lifelong runners is muscle dependent.

UNLABELLED A contributing factor to the loss of muscle mass and strength with adult aging is the reduction in the number of functioning motor units (MUs). Recently, we reported that lifelong competitive runners (master runners = ~66 yr) had greater numbers of MUs in a leg muscle (tibialis anterior) than age-matched recreationally active controls. This suggested that long-term exposure to high levels of physical activity may limit the loss of MU numbers with adult aging. However, it is unknown if this finding is the result of long-term activation of the specifically exercised motoneuron pool (i.e., tibialis anterior) or an overall systemic neuroprotective effect of high levels of physical activity. PURPOSE The purpose was to estimate the number of functioning MUs (MUNEs) in the biceps brachii (an upper body muscle not directly loaded by running) of nine young (27 ± 5 yr) and nine old (70 ± 5 yr) men and nine lifelong competitive master runners (67 ± 4 yr). METHODS Decomposition-enhanced spike-triggered averaging was used to measure surface and intramuscular EMG signals during elbow flexion at 10% of maximum voluntary isometric contraction. RESULTS Derived MUNEs were lower in the biceps brachii of runners (185 ± 69 MUs) and old men (133 ± 69 MUs) than the young (354 ± 113 MUs), but the old and master runners were similar. CONCLUSIONS Although there were no significant differences in MUNE between both older groups in the biceps brachii muscle, with the number of subjects tested here, we cannot eliminate the possibility of some whole-body neuroprotective effect. However, when compared with the remote biceps muscle, a greater influence on age-related spinal motoneuron survival was found in a chronically activated MN pool specific to the exercised muscle.
Behavioral strategies of individuals who have maintained long-term weight losses.

OBJECTIVE The purpose of the present study was to compare the behaviors of individuals who have achieved long-term weight loss maintenance with those of regainers and weight-stable controls. RESEARCH METHODS AND PROCEDURES Subjects for the present study were participants in a random-digit dial telephone survey that used a representative sample of the U.S. adult population. Eating, exercise, self-weighing, and dietary restraint characteristics were compared among weight-loss maintainers: individuals who had intentionally lost > or =10% of their weight and maintained it for > or = 1 year (n = 69), weight-loss regainers: individuals who intentionally lost > or = 10% of their weight but had not maintained it (n = 56), and weight-stable controls: individuals who had never lost > or = 10% of their maximum weight and had maintained their current weight (+/-10 pounds) within the past 5 years (n = 113). RESULTS Weight-loss maintainers had lost an average of 37 pounds and maintained it for over 7 years. These individuals reported that they currently used more behavioral strategies to control dietary fat intake, have higher levels of physical activity (especially strenuous activity), and greater frequency of self-weighing than either the weight-loss regainers or weight-stable controls. Maintainers and regainers did not differ in reported levels of dietary restraint, but both had higher levels of restraint than the weight-stable controls. DISCUSSION These results suggest that weight-loss maintainers use more behavioral strategies to control their weight than either regainers or weight-stable controls. It would thus appear that long-term weight maintenance requires ongoing adherence to a low-fat diet and an exercise regimen in addition to continued attention to body weight.
On the sound pressure transformation by the head and auditory meatus of the cat.

Anesthetized cats were supported by a canvas cradle in a sound-proof chamber and were exposed to a progressive sound wave. A flexible probe microphone was implanted in the external auditory meatus and used to measure the sound pressure in the vicinity of the eardrum. A duplicate probe was used to measure the sound pressure at a point near the center of the cat's head in the absence of the animal. From these measurements the magnitude of the ratio of the sound pressure near the eardrum to that in the free field was determined as a function of frequency. When the ear under study was turned toward the sound source, the sound pressure near the eardrum exceeded the free-field pressure appreciably, except at very low frequencies. By measuring the sound pressure near the tragus, the resonance of the external auditory meatus itself could be determined. The data obtained in this study can be used to compare results of experiments in which the acoustic stimulus is measured in terms of free-field pressures with thos.
On String Languages Generated by Numerical P Systems

Numerical P systems are a class of P systems inspired both from the structure of living cells and from economics. Usually, they are used as devices for computing sets of numbers. In this work, we consider numerical P systems as language generators: symbols are associated with numbers (portions of the “production value”) sent to the environment. The generative capacity of such systems is investigated, both for the standard and the enzymatic form of numerical P systems, having as a reference the families of languages in the Chomsky hierarchy. Key-words: bio-inspired computing, membrane computing, numerical P system, Chomsky hierarchy, universality.
Glutamatergic neurons are present in the rat ventral tegmental area

The ventral tegmental area (VTA) is thought to play an important role in reward function. Two populations of neurons, containing either dopamine (DA) or γ‐amino butyric acid (GABA), have been extensively characterized in this area. However, recent electrophysiological studies are consistent with the notion that neurons that utilize neurotransmitters other than DA or GABA are likely to be present in the VTA. Given the pronounced phenotypic diversity of neurons in this region, we have proposed that additional cell types, such as those that express the neurotransmitter glutamate may also be present in this area. Thus, by using in situ hybridization histochemistry we investigated whether transcripts encoded by genes for the two vesicular glutamate transporters, VGluT1 or VGluT2, were expressed in the VTA. We found that VGluT2 mRNA but not VGluT1 mRNA is expressed in the VTA. Neurons expressing VGluT2 mRNA were differentially distributed throughout the rostro‐caudal and medio‐lateral aspects of the VTA, with the highest concentration detected in rostro‐medial areas. Phenotypic characterization with double in situ hybridization of these neurons indicated that they rarely co–expressed mRNAs for tyrosine hydroxylase (TH, marker for DAergic neurons) or glutamic acid decarboxylase (GAD, marker for GABAergic neurons). Based on the results described here, we concluded that the VTA contains glutamatergic neurons that in their vast majority are clearly non‐DAergic and non‐GABAergic.
Effectiveness of twin-block and Mandibular Protraction Appliance-IV in the improvement of pharyngeal airway passage dimensions in Class II malocclusion subjects with a retrognathic mandible.

OBJECTIVE To test the hypothesis that twin-block and Mandibular Protraction Appliance-IV (MPA-IV) are not effective in improving the pharyngeal airway passage (PAP) dimensions among Class II malocclusion subjects with a retrognathic mandible. MATERIALS AND METHODS Eighty-three subjects ranging in age from 8 to 14 years were divided into four groups. Group I included 30 Class I malocclusion subjects (healthy controls); group II consisted of 16 Class II malocclusion subjects (Class II controls); group III had 16 subjects in whom Class II malocclusion was treated by MPA-IV; and the remaining 21 subjects formed group IV, whose Class II malocclusions were corrected by twin-block appliance. Lateral cephalograms recorded at the beginning of orthodontic treatment in group I subjects and at the beginning and end of follow-up/treatment with functional appliance in group II, III, and IV subjects were analyzed to determine the PAP dimensions. Paired t-test, one-way analysis of variance, and Tukey tests were applied for statistical analysis, and a P-value . 05 was considered statistically significant. RESULTS Soft palate length was decreased significantly in group III (P < .05) and group IV (P < .001) subjects. Soft palate thickness in group IV subjects was increased significantly as compared to group II (P < .05) and group III (P < .01) subjects. The improvement in soft palate inclination in group III and group IV subjects was significant (P < .01). The oropharynx depth was increased significantly in group III (P < .05) and group IV (P < .001) subjects. The depth of the hypopharynx was increased significantly (P < .01) in group IV subjects. CONCLUSIONS The twin-block appliance was more efficient than the MPA-IV in the improvement of PAP dimensions among Class II malocclusion subjects with retrognathic mandible.
Memory Performance for Everyday Motivational and Neutral Objects Is Dissociable from Attention

Episodic memory is typically better for items coupled with monetary reward or punishment during encoding. It is yet unclear whether memory is also enhanced for everyday objects with appetitive or aversive values learned through a lifetime of experience, and to what extent episodic memory enhancement for motivational and neutral items is attributable to attention. In a first experiment, we investigated attention to everyday motivational objects using eye-tracking during free-viewing and subsequently tested episodic memory using a remember/know procedure. Attention was directed more to aversive stimuli, as evidenced by longer viewing durations, whereas recollection was higher for both appetitive and aversive objects. In the second experiment, we manipulated the visual contrast of neutral objects through changes of contrast to further dissociate attention and memory encoding. While objects presented with high visual contrast were looked at longer, recollection was best for objects presented in unmodified, medium contrast. Generalized logistic mixed models on recollection performance showed that attention as measured by eye movements did not enhance subsequent memory, while motivational value (Experiment 1) and visual contrast (Experiment 2) had quadratic effects in opposite directions. Our findings suggest that an enhancement of incidental memory encoding for appetitive items can occur without an increase in attention and, vice versa, that enhanced attention towards salient neutral objects is not necessarily associated with memory improvement. Together, our results provide evidence for a double dissociation of attention and memory effects under certain conditions.
An integrated model of EIS use

This study develops and tests a model of the key determinants of EIS utilization. The validity of the model is tested against data from 216 EIS users in the UK. The results suggest that perceived usefulness positively influence EIS use. Ease of use, information quality, user involvement, subjective norm, and facilitating conditions positively influence both use and perceived usefulness. Participation positively influences information quality and involvement, MIS maturity positively influences information quality, and use experience positively influences perceived ease of use, while, contrary to expectations, training had no influence on beliefs. Implications for theory and practice are outlined
Lipid core peptide targeting the cathepsin D hemoglobinase of Schistosoma mansoni as a component of a schistosomiasis vaccine

The self-adjuvanting lipid core peptide (LCP) system offers a safe alternative vaccine delivery strategy, eliminating the need for additional adjuvants such as CpG Alum. In this study, we adopted the LCP as a scaffold for an epitope located on the surface of the cathepsin D hemoglobinase (Sm-CatD) of the human blood fluke Schistosoma mansoni. Sm-CatD plays a pivotal role in digestion of the fluke’s bloodmeal and has been shown to be efficacious as a subunit vaccine in a murine model of human schistosomiasis. Using molecular modeling we showed that S. mansoni cathepsin D possesses a predicted surface exposed α-helix (A263K) that corresponds to an immunodominant helix and target of enzyme–neutralizing antibodies against Necator americanus APR-1 (Na-APR-1), the orthologous protease and vaccine antigen from blood-feeding hookworms. The A263K epitope was engineered as two peptide variants, one of which was flanked at both termini with a coil maintaining sequence, thereby promoting the helical characteristics of the native A263K epitope. Some of the peptides were fused to a self-adjuvanting lipid core scaffold to generate LCPs. Mice were vaccinated with unadjuvanted peptides, peptides formulated with Freund’s adjuvants, or LCPs. Antibodies generated to LCPs recognized native Sm-CatD within a soluble adult schistosome extract, and almost completely abolished its enzymatic activity in vitro. Using immunohistochemistry we showed that anti-LCP antibodies bound to the native Sm-CatD protein in the esophagus and anterior regions of the gastrodermis of adult flukes. Vaccines offer an alternative control strategy in the fight against schistosomiasis, and further development of LCPs containing multiple epitopes from this and other vaccine antigens should become a research priority.
Person Perception Across the Menstrual Cycle: Hormonal Influences on Social-Cognitive Functioning

Women's reactions to men shift during the menstrual cycle. For example, during the phase of high conception risk, women prefer men with masculinized facial features. A favored explanation for this effect is that women display an enhanced sensitivity to stimuli that have significant reproductive relevance during the phase of the menstrual cycle in which conception risk is high. Consistent with this viewpoint, the present research demonstrated that women's cycle-dependent attentiveness to “maleness” also extends to basic aspects of the person-perception process. Specifically, during the phase of high conception risk, women displayed an enhanced ability both to categorize men and to access associated category-related (i.e., stereotypic) material from semantic memory. The implications of these findings for contemporary treatments of person perception are considered.
D1 and D2 dopaminergic systems in the rat basolateral amygdala are involved in anxiogenic-like effects induced by histamine

Involvement of the dopamine receptors in the basolateral amygdala (BLA) in the effects of histamine on anxiety-like behaviors of the elevated plus maze in male Wistar rats was investigated. The results showed that bilateral intra-BLA injections of histamine (2.5, 5 and 7.5 µg/rat) induced an anxiogenic-like effect, revealed by decreases in percentage of open arm time (%OAT) and open arm entries (%OAE). Intra-BLA administration of dopamine D1 receptor agonist, SKF38393 (0.25 µg/rat), and dopamine D2 receptor agonist, quinpirole (0.03 and 0.05 µg/rat), decreased %OAT but not %OAE. Conversely, intra-BLA administration of dopamine D1 receptor antagonist, SCH23390 (0.5 and 1 µg/rat), and dopamine D2 receptor antagonist, sulpiride (0.3 and 0.5 µg/rat), increased %OAT and %OAE, suggesting an anxiolytic-like effect for both drugs. Interestingly, co-administration of a silent dose of SCH23390 or sulpiride prevented anxiogenic-like effects of SKF38393 and quinpirole, respectively. Conjoint administration of a sub-effective dose of SKF38393 (0.125 µg/rat) or quinpirole (0.01 µg/rat) along with lower doses of histamine (1 and 2.5 µg/rat) induced anxiolytic-like effects. On the other hand, intra-BLA pretreatment with a silent dose of SCH23390 (0.25 µg/rat) or sulpiride (0.1 µg/rat) prevented the anxiogenic-like effect of higher doses of histamine (5 and 7.5 µg/rat). No significant change was observed in total closed arm entries, as an index for motor activity of the animals. It can be concluded that the dopamine D1 and D2 receptors in the BLA may be involved in the anxiogenic-like effects induced by histamine.
