Affect Consciousness and Adult Attachment  [PDF]
Brje Lech, Gerhard Andersson, Rolf Holmqvist
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.39102
Abstract: The concept of affect consciousness refers to the ability to perceive, reflect upon, express and respond to one’s own or other individuals’ affective experiences. The aim of this study was to investigate how affect consciousness and adult attachment are related. Three clinical groups (eating disorders, relational problems, and stress-related problems), and one non-clinical group (total N = 82) completed the Attachment Style Questionnaire and were interviewed using the Affect Consciousness Interview—Self/Other. Results showed associations between high affect consciousness and secure attachment, and between low affect consciousness and insecure attachment. Moreover, attachment style was predicted by consciousness about others’ and own affects in general, and specifically by consciousness about others’ anger and guilt, and by own joy. Affect consciousness as a potential dimension or moderator of attachment merits further investigation.
Effects of a shift from a mixed diet to a lacto-vegetarian diet on some coronary heart disease risk markers  [PDF]
Gunnar Johansson, Brje K?llg?rd, Per-Arne ?ckerman
Open Journal of Preventive Medicine (OJPM) , 2012, DOI: 10.4236/ojpm.2012.21003
Abstract: Background: There is convincing evidence that vegetarians have lower incidence of coronary heart disease, but there is a debate as to why this is the case. Objective: The aim of the study was to investigate whether a shift from a mixed diet to a lacto-vegetarian diet would lead to a decrease in risk for coronary heart diseases indicated by surrogate markers. Design: Twenty volunteers participated in the study (4 men and 16 women, mean age 44 years, range 27 - 61) from a town in western Sweden. Clinical examinations were performed, blood samples were drawn and dietary survey, i.e. repeated 24-h recalls were carried out before (0 months) and 3, 6 and 12 months after the change from a mixed diet to a lacto-vegetarian diet. A dietician educated the volunteers with regard to the vegetarian dietary regimen, organized and taught the vegetarian cooking courses. Results: The dietary shift lead to an increase in the intake of total carbohydrates and fibre and a decrease in fat, protein and sucrose. The coronary heart disease risk markers body weight, body mass index, systolic and diastolic blood pressure, total cholesterol and low-density lipoptrotein cholesterol decreased significantly. Conclusions: There was a decrease in disease risk markers even though the ratio polyunsaturated to saturated fatty acids was unchanged. The main finding in this study is that there was a weight loss, sustained for one year, without any recommendation to decrease the energy intake or any focus on weight reduction.
Gender-Related Survival in Different Stages of Lung Cancer—A Population Study over 20 Years  [PDF]
Gunnar Svensson, Sven-Brje Ewers, Ola Ohlsson, H?kan Olsson
Open Journal of Internal Medicine (OJIM) , 2014, DOI: 10.4236/ojim.2014.43008
Abstract: Introduction: Tumour stage is the most important prognostic factor in non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). The aim of this study was to evaluate if female gender was a prognostic factor in different tumour stages in relation to histology and given therapy. Methods: From 1989-2008, 1497 patients in eastern Scania, in southern Sweden with 202,000 inhabitants, were referred and prospectively registered. Tumour stage, performance status, lung cancer type and primary therapy were registered. Results: In NSCLC, female patients in stages 1 and 2 who were treated with surgery had a better 5-year survival rate (79.4%), compared to males (60.6%; p = 0.0004). Female patients in stage 3 with active therapy (surgery and/or radiotherapy and/or chemotherapy) had a better 5-year survival than males (20.6% vs. 10.5%, respectively, p = 0.0006). Female patients with adenocarcinoma were favourable in stages 1-3. In stage 4, there was no survival difference between females and males. In SCLC, females with limited disease (LD) and active therapy (chemotherapy ± radiotherapy ± surgery) had a higher 5-year survival rate (28%) than males (5.6%); p = 0.001. Females with extensive disease (ED) and active therapy (chemotherapy ± radiotherapy) had a better 5-year survival (3.9%) compared to males (0.7%); p = 0.023. In multivariate analyses, patient performance status at diagnosis was also an independent prognostic factor in all tumour stages of lung cancer. Conclusions: This population-based study corroborates a female survival advantage in NSCLC stages 1-3, but not in metastatic stage 4, and this is also demonstrated for the adenocarcinoma subgroup. The study also confirms better prognosis in
Classical signal model reproducing quantum probabilities for single and coincidence detections
Andrei Khrennikov,Brje Nilsson,Sven Nordebo
Physics , 2011, DOI: 10.1088/1742-6596/361/1/012030
Abstract: We present a simple classical (random) signal model reproducing Born's rule. The crucial point of our approach is that the presence of detector's threshold and calibration procedure have to be treated not as simply experimental technicalities, but as the basic counterparts of the theoretical model. We call this approach threshold signal detection model (TSD). The experiment on coincidence detection which was done by Grangier in 1986 \cite{Grangier} played a crucial role in rejection of (semi-)classical field models in favor of quantum mechanics (QM): impossibility to resolve the wave-particle duality in favor of a purely wave model. QM predicts that the relative probability of coincidence detection, the coefficient $g^{(2)}(0),$ is zero (for one photon states), but in (semi-)classical models $g^{(2)}(0)\geq 1.$ In TSD the coefficient $g^{(2)}(0)$ decreases as $1/{\cal E}_d^2,$ where ${\cal E}_d>0$ is the detection threshold. Hence, by increasing this threshold an experimenter can make the coefficient $g^{(2)}(0)$ essentially less than 1. The TSD-prediction can be tested experimentally in new Grangier type experiments presenting a detailed monitoring of dependence of the coefficient $g^{(2)}(0)$ on the detection threshold.
Laguerre Entire Functions and Related Locally Convex Spaces
Yuri Kozitsky,Lech B. Wolowski
Mathematics , 1998,
Abstract: A scale of the Frechet spaces of exponential type entire functions of one complex variable is considered. Certain special properties of subsets of these spaces consisting of Laguerre entire functions, which are obtained as uniform limits on compact subsets of the complex plane of polynomials with real nonpositive zeros only, are described. A class of infinite order differential operators which act between these Frechet spaces is inrtoduced and studied. In particular, it is shown that this class preserves the set of Laguerre entire functions. The results obtained are then used to obtain and to study the solutions of a certain initial value problem.
Flotation—A New Method to Circumvent PCR Inhibitors in the Diagnosis of Lawsonia intracellularis
Magdalena Jacobson,B rje Norling,Anders Gunnarson,Anna Aspan
International Journal of Microbiology , 2009, DOI: 10.1155/2009/410945
Abstract: The obligate intracellular bacterium Lawsonia intracellularis causes enteritis and poor growth in weaned pigs. Cultivation is difficult and diagnosis ante mortem is mainly based on techniques such as polymerase chain reaction. However, false negative results caused by the presence of PCR-inhibitory factors constitute a problem. This study aimed to develop and evaluate a new technique, flotation, to separate L. intracellularis from inhibitors in faeces prior to PCR. The technique was evaluated by comparison to two previously evaluated and commonly used methods, preparation by boiling lysate combined with nested PCR and preparation by a commercial kit combined with conventional PCR. Continuous density centrifugation of faecal samples containing L. intracellularis suggested the buoyant density of the microbe to be between 1.064 and 1.077 g/mL. Several flotation setups were tested to achieve optimal separation of the microbe from inhibitors and faecal particles. The finally selected setup floated whole L. intracellularis from the application site at the bottom to the upper part of the gradient while inhibitory components mainly remained in the bottom. PCR was performed directly on material recovered from the upper interphase. The method was evaluated on 116 clinical samples. As compared to sample preparation by boiling combined with nested PCR, fewer samples were inhibited but also fewer positives were identified. In comparison to preparation by a commercial kit combined with conventional PCR, presently used for routine diagnosis, similar results were obtained. However, the new method was comparably faster to perform. The new method, based on flotation of Lawsonia intracellularis combined with conventional PCR, was well suited for routine diagnosis.
Gene expression pattern of the epidermal growth factor receptor family and LRIG1 in renal cell carcinoma
Marcus Thomasson, H?kan Hedman, Brje Ljungberg, Roger Henriksson
BMC Research Notes , 2012, DOI: 10.1186/1756-0500-5-216
Abstract: Gene expression levels of EGFR–family members and LRIG1 were analyzed in 104 RCC samples, including 81 clear cell RCC (ccRCC), 15 papillary RCC (pRCC), and 7 chromophobe RCC (chRCC) by quantitative real-time RT-PCR. Associations between gene expression levels and clinical data, including tumor grade, stage, and patient survival were statistically assessed.Compared to kidney cortex, EGFR was up-regulated in ccRCC and pRCC, LRIG1 and ERBB2 were down-regulated in ccRCC, and ERBB4 was strongly down-regulated in all RCC types. ERBB3 expression did not differ between RCC types or between RCC and the kidney cortex. The expression of the analyzed genes did not correlate with patient outcome.This study revealed that the previously described up-regulation of EGFR and down-regulation of ERBB4 occurred in all analyzed RCC types, whereas down-regulation of ERBB2 and LRIG1 was only present in ccRCC. These observations illustrate the need to evaluate the different RCC types individually when analyzing molecules of interest and potential biological markers.Renal cell carcinoma (RCC) consists of various tumor types [1]; clear cell RCC (ccRCC) accounts for approximately 70-80 % of the RCCs, papillary RCC (pRCC) for 10-15 % of cases, chromophobe RCC (chRCC) for approximately 5 %, and collecting duct carcinoma for less than 1 % of RCCs. Approximately 4-5 % of RCCs do not fit the histopathological criteria and are referred to as unclassified carcinomas [1]. The RCC types represent tumor groups with different genetic and molecular properties, as reviewed in [2] and [3]. When RCC types are analyzed collectively, the results predominantly reflect the properties of ccRCC, since this type accounts for the majority of RCC cases. Previous studies have revealed altered expression of epidermal growth factor (EGF) receptor (EGFR)-family members and their endogenous inhibitor leucine-rich and immunoglobulin-like domains 1 (LRIG1) in renal cell carcinoma (RCC). The EGFR family consists of four rece
Neuromusculoskeletal disorders in the neck and upper extremities among drivers of all-terrain vehicles – a case series
Brje Rehn, Tohr Nilsson, Bengt J?rvholm
BMC Musculoskeletal Disorders , 2004, DOI: 10.1186/1471-2474-5-1
Abstract: This study was based on a case series analyzed according to a case-case comparison design. The study population consisted of 60 male subjects, including professional drivers of forest machines (n = 15), snowmobiles (n = 15), snowgroomers (n = 15) and referents from the general population (n = 15) all of whom had reported neck pain in a questionnaire and underwent an extensive physical examination of the neck and upper extremities. Based on symptom history, symptoms and signs, and in some cases chemical, electroneurographical and radiological findings, subjects were classified as having a nociceptive or neuropathic disorder or a mix of these types.The occurrence of asymmetrical and focal neuropathies (peripheral nervous lesion), pure or in a mix with a nociceptive disorder was common among cases in the ATV driver groups (47%–79%). This contrasted with the referents that were less often classified as having asymmetrical and focal neuropathy (27%), but instead had more nociceptive disorders. The difference was most pronounced among drivers of snowgroomers, while drivers of forest machines were more frequently classified as having a nociceptive disorder originating in the muscles.This study found a high prevalence of assymetrical and focal neuropathies among drivers with pain in the neck, operating various ATVs. It seems as if exposure to shock-type whole-body vibration (WBV) and appurtenant unfavorable postures in ATVs may be associated to peripheral nervous lesions.Among drivers, complaints concerning the musculoskeletal system are most frequently reported from the neck, shoulders and lower back [1-4]. Whole-body vibration (WBV) is associated with low back pain and studied with epidemiological [5,6], laboratory [7-9] and clinical [10,11] methods. Musculoskeletal disorders in the neck and shoulder regions have not been as extensively studied as the lower back and the association with exposure to WBV is considered weak [12,13].Rehn et al [14] found that drivers of all-t

Neuromusculoskeletal disorders in the neck and upper extremities among drivers of all-terrain vehicles – a case series
Rehn Brje,Nilsson Tohr,J?rvholm Bengt
BMC Musculoskeletal Disorders , 2004,
Abstract: Background The purpose of this study was to investigate whether professional drivers of all-terrain vehicles (ATVs) with neck pain have a different array of neuromusculoskeletal disorders in the neck and upper extremities than a referent group with neck pain from the general population. It is hypothesized that exposure to shock-type vibration and unfavorable working postures in ATVs have the capacity to cause peripheral nervous lesions. Methods This study was based on a case series analyzed according to a case-case comparison design. The study population consisted of 60 male subjects, including professional drivers of forest machines (n = 15), snowmobiles (n = 15), snowgroomers (n = 15) and referents from the general population (n = 15) all of whom had reported neck pain in a questionnaire and underwent an extensive physical examination of the neck and upper extremities. Based on symptom history, symptoms and signs, and in some cases chemical, electroneurographical and radiological findings, subjects were classified as having a nociceptive or neuropathic disorder or a mix of these types. Results The occurrence of asymmetrical and focal neuropathies (peripheral nervous lesion), pure or in a mix with a nociceptive disorder was common among cases in the ATV driver groups (47%–79%). This contrasted with the referents that were less often classified as having asymmetrical and focal neuropathy (27%), but instead had more nociceptive disorders. The difference was most pronounced among drivers of snowgroomers, while drivers of forest machines were more frequently classified as having a nociceptive disorder originating in the muscles. Conclusion This study found a high prevalence of assymetrical and focal neuropathies among drivers with pain in the neck, operating various ATVs. It seems as if exposure to shock-type whole-body vibration (WBV) and appurtenant unfavorable postures in ATVs may be associated to peripheral nervous lesions.
