Aortic Body Tumors in Dogs
The purpose of this essay was to review the literature and describe the patophysiology, diagnosis, microscopic and macroscopic appearance of Aortic body tumors in dogs. The tumors originate from the chemoreceptor organs situated at the base of the heart. The chemoreceptor organs are neuroendocrine cells responsible for surveillance of changes in e.g. the blood pH. Aortic body tumors are rare and represent 7 % of the total cases of primary cardiac tumors in canines.
Undersökning av global epigenetisk metyleringsstatus hos juvertumörer på hund :
Mammary tumors are the most frequent type of tumors in bitches in Sweden. Many
studies have been published concerning mammary tumors, but there is still much to
be learned about this disease.
One has, since some time ago, had the knowledge that addition to or removal of
methyl groups to genes can inhibit or activate gene-expression. Methylation and
demethylation is a normal phenomenon in the body and it is essential for the
development and survival of the individual. The risk of developing a tumor disease is
increased if the global methylationstatus is changed; if oncogenes demethylates
(activates) or if tumor suppressor genes methylates (inactivates). In the human
medicine one has seen that there are differences in methylationstatus between
different tumors.
In this study tumor and normal tissue from ten dogs were examined with regard to
methylationstatus.
The RECK gene and invasive cancer development : the significance of RECK in angiogenesis and inhibition of matrix metalloproteinases
The RECK gene is a relatively new discovered gene with important implications for cancer research. The research has been primarily concentrated on the human gene with the ultimate aim to identify the invasive characteristics. Up regulated RECK is linked to significantly prolonged survival rates in patients with severe forms of malignancies.
RECK is normally expressed in all cells of the body and has an important role in the balance between destructive and constructive features of the extracellular matrix. The RECK protein is a membrane-bound glycoprotein that inhibit matrix metalloproteinases which has the function of breaking down the ECM. There is a significant correlation between RECK gene expression and the formation of new vessels, presumably via the mediation of VEGF which is an important and powerful inducer of angiogenesis.
4-1BB is up-regulated in human mast cells, when exposed to tumor conditioned medium
Mast cells have for a long time been known to accumulate around tumors (Maltby et al., 2009). Studies show that they may be important and sometimes essential in tumor angiogenesis, tumor growth and metastasis of tumors (Soucek, et al., 2007; Xiang et al., 2010). In an expression array study (Wensman et al, submitted manuscript) performed on mouse mast cells exposed to tumor conditioned medium, the gene 4-1BB was among the most up-regulated genes compared to control medium. 4-1BB codes for a membrane receptor protein of the tumor necrosis factor superfamily and has been shown to be important in T cell regulation in tumor diseases. This study was performed to investigate if human mast cells up-regulate 4-1BB when they get exposed to tumor conditioned medium.
Kroppsuppfattning hos värnpliktiga män
Body awareness is a term that refers to a person´s perception and knowledge about his or her body. It includes proportion, size, weight, contour and image of ones body. The Ben- Tovim Walker Body Attitudes Questionnaire (BAQ) contains 44 questions concerning the different aspects of body awareness: Feeling fat, Body disparagement, Strength and fitness, Salience of weight, Attractiveness and Lower body fatness. The purpose of this study was to investigate body awareness among men in military recruit training. BAQ was distributed to fifty recruits for military service in Boden.
Comparison of Different Electrophoretic Methods for Haptoglobin Phenotyping and an Investigation in Patients with Abdominal Aortic Aneurysm
Haptoglobin is an acute phase protein with important biological role because of its capacity to bind to haemoglobin. Haptoglobin exists in three major genetic polymorphism types: Hp1-1, Hp2-1 and Hp2-2, the distribution of which has been associated with abdominal aortic aneurysm (AAA), an asymptomatic aortic disease common among men older than 65 years. Five different electrophoretic methods were tested according to their ability to separate the haptoglobin phenotypes. The detection was based on a produced hemolysate of blood in which haemoglobin binds to haptoglobin thereby forming a complex that can be detected by specific haemoglobin staining using TMB-dihydrochloride and hydro peroxide as substrate resulting in an azure-green color of the bands. Samples from 15 patients who had suffered surgery for not broken AAA, that is more than5.0 cmaortic diameter, and 15 samples from matched controls were analyzed. Among the five tested electrophoretic methods best migration and separation was seen on the pre-cast agarosgel Hydragel HR on the instrument Hydrasys. The other four methods gave less successful results.
Reference interval for urinary catecholamines and methylated catecholamines analysed using HPLC
Catecholamines are stress hormones that are produced and released by a rare tumor called pheochromocytoma. This tumor can cause hypertension which if undiagnosed and untreated leads to death. Since good therapy is available, it is important to find the tumor in time. The most common way to diagnose the tumor is measurement of the biochemical markers; catecholamines and their metabolites, methylated catecholamines.After observation that almost all normetanephrine results for women were higher than the upper reference limit and therefore pathological, the accuracy of the present reference intervals was questioned. Therefore new reference intervals for both urinary catecholamines and methylated catecholamines were developed by analysis of 46 samples using HPLC.

The foundation for this thesis lies in whether or not, and how, the body representation in printed commercials, specific products directed to the body (shampoo, body lotion etc.), has changed during the last fifty years. Four years have been chosen because of the changes in society that we believe might have had an impact. The commercials that have been picked out are the ones that best represent the general view of the body. We have found that the changes when it comes to body presentation has followed the social development to a certain degree, but it is difficult to say how much the society has had an affect on the body ideal in advertising. Representations of the male body is something that has escalated since the early 70?s, fifteen years earlier few commercials was made with male models, and the few there were, never showed more than the face.
Unga indiska kvinnors kroppsmedvetande ur ett kulturellt perspektiv: enkätstudie på universitetsstudenter i Indien

Tjocka kroppar och smala platser : om överviktiga personers erfaranheter av att vistas i offentliga rum
How is the fat body constructed in public spaces? This essay deals with the experiances of five participants, being fat in public spaces. The fat body is often constructed as "matter out of place", more or less expected to be invisiable in public spaces. But living with a fat body isnt all about assimilation, wearing black clothes to fit in or staying at home in fear of facing comments of your body. More than being a body constructed as improperiate in public spaces, the participants view can be described as "revolting".
Kön, kroppsbild och dysfunktionella tankar : en sambandsstudie
Body esteem is the affective aspect of body image, which is shaped by social experience. Compared with men, women have a more negative body image, which is more frequently correlated with depression and dysfunctional thoughts, especially in the case of eating disorders. The purpose of the present study was to examine gender differences in body esteem and its subcategories, and to find out whether there exists a stronger link between negative body esteem and higher levels of dysfunctional thoughts in women. The relationship between body esteem, dysfunctional thoughts and mental illness was examined. Participants were 73 college students doing social sciences and sports training educations.

E=(motion)2 : Mellan rörelse och dans
Mainstream contemporary phenomenology understands the phenomenology of movement and dance through ?the lived body? of Merleau-Ponty. This paper rather suggests a phenomenology of movement and dance based on an understanding through ?the danced body? with ability to meta-feeling. It is here argued that we need to use a phenomenology of dance to understand the phenomenon of movement whatsoever.
