Comparative Analysis Of The Its Rdna Sequence And Nutrient Compositions Of An Un-Named Ganoderma Species In Australia, Li-Xia Liu, Peter Howe, Chen-Wei Su, Fei Sun, Ren Zhang

Faculty of Health and Behavioural Sciences - Papers (Archive)

An Australian species of Ganoderma genus (temporally named Ganoderma nt) mistaken for Garoderma lucidum, a well-known herbal medicine, was examined with internal transcribed spacer ribosomal DNA (ITS rDNA) sequence as an aid to the taxonomy. Variation between G. nt and G. lucidum in the ITS rDNA sequence was 2% - 4 %. Also nutrient value in this species was analyzed compared with G. lucidum. G. nt had similar contents to G. lucidum in polysaccharides and monosaccharides on dry mass base in fruit body. However, G. nt fruit body had higher soluble protein (14 mg/g dry mass) and fatty acids (5.6 …

Increased Post-Immersion Afterdrop Following B-Adrenergic Blockade, Annerieke Zeyl, Cassandra Haley, Pornkamon Thoicharoen, Laura Welschen, Nicole Sinnema, Nigel A. S Taylor, Arthur Jenkins

Faculty of Health and Behavioural Sciences - Papers (Archive)

It is well established that, during the initial rewarming from mild hypothermia, core temperature continues to decrease before returning towards its pre-immersion state (I). This phenomenon is known as the afterdrop, and has been ascribed to circulatory changes at the periphery, as well as to continued core-to-periphery thermal conduction, both of which may account for continued central-body heat loss after removal from the cold (2,3,4). In a recent series of experiments, in which we studied interactions between cold-water immersion, B-adrenergic blockade, plasma leptin concentration, rewarming and skin blood flow control, we also investigated the afterdrop. Our observations have revealed that …

Is Experience With One Illicit Drug Associated With Perceptions Of The Believability Of Anti-Drug Messages?, Sandra C. Jones, John R. Rossiter

Faculty of Health and Behavioural Sciences - Papers (Archive)

Cannabis (marijuana) use is on the increase in many countries, particularly among teenagers. Information dissemination is likely to become the main vehicle for minimising the harms associated with cannabis use. Thus there is a clear need to develop informative and convincing communication strategies to target young (potential and incipient) cannabis users. Cognitive dissonance theory, as well as research with warning labels on other products, suggests that young people who currently use cannabis will find the information about cannabis and the infonnation about other drugs (with which they have no experience) less believable than will non-users. This study finds support for …

Breast Cancer Detection Messages In Australian Print Media Advertising - Are They Promoting Correct Information?, Sandra C. Jones, John R. Rossiter

Faculty of Health and Behavioural Sciences - Papers (Archive)

With breast cancer now the leading cause of cancer deaths among women in the western world, correct information about detection and treatment is vitally important. The media are often accused of conveying inaccurate information in their editorial coverage of health issues, but few studies have examined the accuracy of information in media advertising. In this study of breast cancer detection ads in Australian magazines and newspapers, many instances of misleading information were found. As the print media have a major influence on women's health beliefs, these findings have serious implications for health communication policy regarding socially responsible advertising.

Is The Technology Acceptance Model A Valid Model Of User Satisfaction Of Information Technology In Environments Where Usage Is Mandatory?, Dave Mather, Peter Caputi, Rohan Jayasuriya

Faculty of Health and Behavioural Sciences - Papers (Archive)

The validity of the two models based on the extended Technology Acceptance Model (Venkatesh and Davies, 2000) in predicting user satisfaction of an incident reporting system in a mandated setting was tested using 84 employees from a large manufacturing company. The models differed in how the construct, subjective norm was represented. Although the results indicated that both models fitted the data, the anticipated relationship between subjective norms and user satisfaction was not supported. Furthermore, some of the antecedent factors did not predict perceived usefulness as anticipated.

Help-Seeking Patterns For Suicidal And Non-Suicidal Problems In Two High School Samples, Coralie J. Wilson, Joseph V. Ciarrochi, Debra Rickwood, Frank P. Deane

Faculty of Health and Behavioural Sciences - Papers (Archive)

Few distressed young people seek professional psychological help for either personal-emotional problems or suicidal ideation. This paper describes two studies that have examined help-seeking patterns in two contrasting high school populations. Two hundred and sixty four Il1awarra public high school students and 307 Queensland private high school students completed a questionnaire measuring intentions to seek help from a variety of fonnal and informal sources, in addition to no-one for personal-emotional and suicidal problems. Students in both samples indicated they would seek help from different sources of help for different problem types, but friends were rated as the most likely source …

Consistent Stereoscopic Information Increases The Perceived Speed Of Vection In Depth, Stephen A. Palmisano

Faculty of Health and Behavioural Sciences - Papers (Archive)

Previous research found that adding stereoscopic information to radially expanding optic flow decreased vection onsets and increased vection durations (Palmisano S, 1996 Perception & Psychophysics 58 1168-1176). In the current experiments, stereoscopic cues were also found to increase perceptions of egospeed and self-displacement during vection in depth - but only when these cues were consistent with monocularly-available information about self-motion. Stereoscopic information did not appear to be improving vection by increasing the perceived maximum extent of displays or by making displays appear more three-dimensional. Rather, it appeared that consistent patterns of stereoscopic optic flow provided extra, purely binocular information about …

Influence Of Protein Tyrosine Kinases On Cell Volume Change-Induced Taurine Release, Herminia Pasantes-Morales, Rodrigo Franco

School of Veterinary and Biomedical Sciences: Faculty Publications

Taurine efflux occurs in association with cell swelling in both hyposmotic and isosmotic conditions and during cell shrinkage in apoptotic death. Release occurs through a leak pathway, is largely Ca²⁺-independent and is sensitive to Cl^– channel blockers. Taurine efflux elicited by hyposmolarity is reduced or suppressed by tyrosine kinase blockers and increased by tyrosine phosphatase inhibitors. The specific kinases involved are still unknown and may be different in the various cell types. Non-receptor and scr-related protein kinases have been identified in some cells as elements that directly phosphorylate the taurine efflux pathway. Possible tyrosine kinase targets are …

Mechanisms Counteracting Swelling In Brain Cells During Hyponatremia, Herminia Pasantes-Morales, Rodrigo Franco, Benito Ordaz, Lenin D. Ochoa

School of Veterinary and Biomedical Sciences: Faculty Publications

Water gain in the brain consequent to hyponatremia is counteracted by mechanisms that initially include a compensatory displacement of liquid from the interstitial space to cerebrospinal fluid and systemic circulation and subsequently an active reduction in cell water accomplished by extrusion of intracellular osmolytes to reach osmotic equilibrium. Potassium (K⁺), chloride (Cl^–), amino acids, polyalcohols, and methylamines all contribute to volume regulation, with a major contribution of ions at the early phase and of organic osmolytes at the late phase of the regulatory process. Experimental models in vitro show that osmolyte fluxes occur via leak pathways …

Introduction Of The Precise Ts Measurement For Fisheries Acoustics, Kouichi Sawada, Yoshimi Takao, Yoichi Miyanohana, H. Tuncay Kinacigi̇l

Turkish Journal of Veterinary & Animal Sciences

Two methods to measure target strength (TS) are introduced and compared with each other. One is the suspension method, and the other is the split-beam method. Each of them is representative of control and in situ methods, respectively. In addition, a morphological investigation of a swimbladder in a pressure tank, and the development of an instrumented package of acoustic and optical systems, are also introduced. The former is to reveal the degree of TS variation by the vertical movement of fish, and the latter is to obtain precise TS and fish behavior by the echo trace analysis method.

Role Of Bcl-2 Family Members In Caspase-Independent Apoptosis Due To Chlamydia Infection, Jean-Luc Perfettini, John C. Reed, Nicole Israel, Jean-Claude Martinou, Alice Dautry-Varsat, David M. Ojcius

All Dugoni School of Dentistry Faculty Articles

Infection with an obligate intracellular bacterium, the Chlamydia trachomatis lymphogranuloma venereum (LGV/L2) strain or the guinea pig inclusion conjunctivitis serovar of Chlamydia psittaci, leads to apoptosis of host cells. The apoptosis is not affected by a broad-spectrum caspase inhibitor, and caspase-3 is not activated in infected cells, suggesting that apoptosis mediated by these two strains of Chlamydia is independent of known caspases. Overexpression of the proapoptotic Bcl-2 family member, Bax, was previously shown to induce caspase-independent apoptosis, and we find that Bax is activated and translocates from the cytosol to the mitochondria in C. psittaci-infected cells. C. psittaci-induced apoptosis is …

Stair use significantly increased after the first intervention phase (P 0.02), but after the intervention was removed stair use decreased back towards …

P300 Amplitude Is Determined By Target-To-Target Interval, C. J. Gonsalvez, J. Polich

Faculty of Health and Behavioural Sciences - Papers (Archive)

P300 event-related brain potential (ERP) measures are affected by target stimulus probability, the number of nontargets preceding the target in the stimulus sequence structure, and interstimulus interval (ISI). Each of these factors contributes to the target-to-target interval (TTI), which also has been found to affect P300. The present study employed a variant of the oddball paradigm and manipulated the number of preceding nontarget stimuli (0, 1, 2, 3) and ISI (1, 2, 4 s) in order to systematically assess TTI effects on P300 values from auditory and visual stimuli. Number of preceding nontargets generally produced stronger effects than ISI in …

Marlboro''S Marketing In Western Europe: Is It Ethical?, Sandra C. Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

There has been considerable publicity in the United States and Australia opposing the cigarette marketing efforts of British and U.S. tobacco companies in Eastern Europe. However, little attention has been paid to the marketing campaigns ofthe same companies in Western Europe, perhaps on the assumption that Western Europeans are too sophisticated to fall for the marketing tricks that have worked elsewhere over the last several decades. However, smoking rates are on the increase in many Western European countries, where tobacco advertising is largely unregulated. This paper analyzes magazine advertising for the Marlboro brand targeted at young adults in The Netherlands …

In hospitals and other Healthcare settings, increasingly, hands-on computer use is becoming an important behaviour for effective job perfonnance for health professionals. As the pre-employment (professional) training is provided at a number of different settings the exposure health workers have to computing will vary. Providing training and support to such end-users becomes a complex problem. In addition, based on their prior exposure to computer technology in their work place individuals will have different experiences that make implementation of such systems more complex. Individual …

Fat In Food And The Obesity Epidemic, Linda C. Tapsell

Faculty of Health and Behavioural Sciences - Papers (Archive)

Dietary fat is strongly implicated in the development of insulin resistance and obesity, both major public health problems today. While the amount of dietary fat is relevant, the type of fat is important in fuel utilisation, storage and appetite regulatory mechanisms. Human calorimetry research confirms the importance of dietary fat in energy balance, but more work needs to be done to uncover the impact of type of dietary fat in weight control. Population and intervention research confirm the importance of fat in dietary interventions, bearing in mind the contribution of physical activity to energy balance. The food industry has an …

From test-day milk yields, 305 d milk yields were estimated by the Holland (Lactation yield = mean of test day …

Expression Of Subunits Of Ampa-Type (Ionotropic) Glutamate Receptors In The Rat Spinal Cord, Mümtaz Nazli, Zafer Soygüder, Ahmet Çarhan

Turkish Journal of Veterinary & Animal Sciences

The distribution of ionotropic glutamate receptor subunits (GluR1-4), considered a-amino-3-hydroxy-5-methyl-4-isaxole propionic acid type (AMPA-type), was investigated in the rat spinal cord by immunocytochemistry. Different distributions of the AMPA-type glutamate receptor subunits were observed in the spinal cord. Immunolabelling with antibodies to both GluR1 and GluR2/3 revealed intensive staining in the dorsal horn, while staining for GluR2/3 and GluR4 revealed dense motor neurones in the ventral horn. These results suggest that in the rat spinal cord AMPA-type glutamate receptors vary in composition according to the region where they are expressed.
