Bremsningens effekter hos häst : utvärderat med hjälp av termografi, hormonanalyser och hematologi

Twitching is frequently used in horse management because of its sedating and pain-relieving effects. In this study, the effects on the horse?s nervous system by twitching were investigated by thermography of the skin temperature. The temperature is regulated by the sympathetic nervous system through postganglionic sfincters at the capillaries of the skin. The effects on the endocrine activity have also been studied by the measuring of ACTH and cortisol in blood plasma.

Selektiv uppmärksamhet och reaktion på stress

Tidigare forskning har visat att selektiv uppmärksamhet (selective attention; SA) mot hotfulla stimuli kan predicera emotionella responser på stressfyllda händelser. Syftet med denna studie var att undersöka sambandet mellan sårbarhet för ångest i form av SA och fysiologiska samt självskattade stressreaktioner på en laboratoriestressor. Ett negativt samband mellan fysiologisk stressreaktion och SA samt ett positivt samband mellan självskattad stressreaktion och SA förväntades. Skillnaden i hudkonduktansreaktivitet (skin conductance reactivity; SCR) på subliminalt presenterade hotfulla och neutrala stimuli hos 41 försökspersoner utgjorde mått på SA i denna studie. Försökspersonerna utsattes senare för en laboratoriestressor samtidigt som hjärtfrekvensvariabilitet (heart rate variability; HRV) och hudkonduktansvariabilitet (skin conductance variability; SCV) registrerades.

Surgical stress response in dogs diagnosed with pyometra undergoing ovariohysterectomy

The aim of this study was to investigate the intraoperative surgical stress response in dogs undergoing ovariohysterectomy and to compare acepromazine and medetomidine as premedications. 15 dogs diagnosed with pyometra were used in this study. Blood pressure and heart rate were used as parameters to measure surgical stress response. The surgery was divided into four phases. Phase 0 was the period 10 minutes before the skin incision, phase 1 was skin incision and opening of abdomen, phase 2 was manipulation of uterine horns, ligation and transection of mesovarium and phase 3 was ligation of cervix, removal of organs and closing the abdomen. The results showed that phase 2 was the most intense phase of surgical stress, regardless of which premedication the dogs received. When acepromazine and medetomidine were compared the results showed that within phase 3, all dogs that were given medetomidine had higher blood pressure compared to dogs that were given acepromazine. The dogs that were given acepromazine had higher heart rate than the dogs that were given medetomidine in phase 0, phase 2 and phase 3. .

Barns erövrande av litteracitet i den fria aktiviteten - miljöns och materialets betydelse

The aim of this study is, from a norm-critical approach, to find, investigate and analyse human representation in the visual culture of one preschool in order to understand if the children enrolled are represented or not. The research questions are: In what ways is there imagery of human representations in images and materials designed for play? What skin-colors and origins are dominant in the data collected?We carried out a qualitative study in the form of visual ethnography. This method allowed us to use a combination of different data collection tools such as photography and ethnographic field notes to collect our data. The photographs we took of images and material used for play, was then analysed through semiotic picture analysis.

Oralt intag av grönt te och dess effekt på uppkomsten av UV-inducerad hudrodnad, erythema solare ? En systematisk litteraturöversikt

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Oral intake of green tea and its effect on the appearance of UV-induced erythema, erythema solare ? A systematic literature reviewAuthors: Ernita Antoni Mulliqi and Pernilla GustafssonSupervisor: Sofia KlingbergExaminer: Ingrid LarssonProgramme: Dietetics programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 10, 2013Background: UV irradiation of the skin can cause erythema, clinically called erythema solare. The condition can exert pain as well as discomfort and may in the long term lead to negative effects including skin cancer. Green tea contains catechins which are substances with anti-inflammatory effect that may have positive effects on the skin. The intake of green tea is believed to have a protective effect against UV irradiation, since green tea extracts in lotions in previous studies have shown to increase the skin tolerance level against UV irradiation.Objective: To examine the scientific basis and determine whether an oral intake of green tea has a protective effect against UV-induced erythema.Search strategy: Searches in the scientific databases PubMed and Scopus were made to find suitable articles.

Spädbarns smärtupplevelse lindras av föräldradelaktighet : En systematisk litteraturstudie

AbstraktBakgrundInnan 90-talet betraktades spädbarn inte kunna känna smärta. Idag finns annan förståelse för att spädbarn känner smärta och att spädbarn uppfattar större smärta än vuxna vid samma smärtstimuli. Föräldrar och spädbarn bildar ett system där föräldra är spädbarns trygga bas. Föräldrars delaktighet ger trygghet vilket gör att spädbarn kan hantera sjukdom och smärta. Förebygga och minska smärtupplevelsen hos spädbarn främjar deras välbefinnande och utveckling.SyfteBeskriva hur spädbarns smärtupplevelse lindras av föräldradelaktighet.MetodEn systematiskt litteraturstudie med sökning i Cinahl och Pubmed där 6 kvantitativa artiklar inkluderades i studien.

Mörkerkörning: Realtidssimulering och visualisering av fordonsbelysning för mörkerkörning i körsimulator

To give a realistic impression in a driving simulator for nighttime driving, there are many challenging aspects to consider. One of the most important aspects is the illumination caused by the headlights of the own vehicle. To give a realistic impression there is the need to consider the characteristics of the headlight in use to be able to represent main and dipped beam, but also to represent different models and types of headlights. Another important aspect is the dazzling effects caused by the light cast by other vehicles upon the driver. These effects are not only important to give a realistic and visually appealing simulation, but also to simulate blinding effects which may affect the drivers ability to perceive the traffic environment to a large degree.

Comparison of real-time PCR assays for screening of meticillin-resistant Staphylococcus aureus

Staphylococcus aureus belongs to the normal flora. Many healthy people are colonized by the bacterium mainly in the nose but also on the skin and on other mucous membranes without showing symptoms. After damage to the skin, the bacterium can enter the wound and cause infections. Methicillin-resistant S. aureus (MRSA) is resistant to b-lactam antibiotics such as penicillin and methicillin.

Trycksår : ? undersköterskors kunskaper om att förebygga trycksår

Background and aims: The population of older people in our society is increasing. Agerelated changes in the skin results in a diminished perception of pain and pressure and a decreased microcirculation in the skin affects its ability to adapt to injury. Occurrence of pressure sore on geriatrikal clinics are 5-10%, witch means that between five and ten thousand patients gets daily treat for pressure sores. When the patient gets a pressure sore the need for help increases. A common apprehension is that if the patient?s affects with pressure sores it?s because of deficiency in care.

Patienters uppfattning om den information och det stöd de fått och behöver för att hantera sin psoriasis

Background: One of the healthcare tasks is to inform and support patients. Information and support is very important for the management of the disease in patients with psoriasis. Healthcare often focuses on the medical aspects and can easily forget about the individual behind the disease.Aim: To explore what kind of information and support patients with psoriasis receive and need to manage their skin disease.Method: Quantitative study with descriptive design and qualitative elements by analysis of the questionnaire with open questions. The study included 22 participants.Findings: The majority of participants responded that they had received information about various therapies, medications and generally about psoriasis. The information participants most often responded they needed, was essentially continuous information and updates on treatments and knowledge about psoriasis according to medical science.

Tillverkning av mikronålar för medicinsk tillämpning

Transdermal drug delivery, besides painfulinjections with syringes, has long been associatedwith small size particle pharmaceuticals, which candiffuse through the skin. This method of drugadministration has only been applicable on a smallnumber of drugs, where active molecules are smalland delivery time should or can be long.Other drug delivery options are oral administrationand injection with hypodermic needles (ordinaryhospital syringes). In oral administration thestomach and liver tend to dissolve the drug and theeffect becomes more difficult to anticipate, anddrug delivery rates difficult to control. Hypodermicneedles are used as a mean of drug injectiondirectly into the bloodstream. This method ispainful and risks infection due to tissue damageand skin penetration.One way to get a painless non-damaging techniquewith high delivery rate that still can delivery largemolecules is to manufacture an array of microscopichollow needles and equip them with a pumping unitthat delivers the correct amount of drugs.This thesis shows the technique and possibility ofmanufacture micromachined needles using low costtechniques of Ion Track Technology (radiation ofheavy ions creates porous materials), electrolessdeposition (non-current activated wet chemistrymethod of depositing metal) and electroplating.

Kollision deformation med fokus på solida objekt

En realistisk simulation kräver att alla simulerade objekten ska interaktivt och dynamiskt animeras. Delar av objektens kropp ska deformeras och andra delar ska sönderfalla vid en krock med ett annat objekt. De flesta 3d applikationer har som gemensamt vissa tekniker som används vid dynamiska simulationer. Tyvärr så finns det inte en smidig och snabb teknik för att deformera solida objekt vid kollisioner, detta gäller även Maya som jag använde i detta arbete. Detta arbete ska visa en smidig teknik att deformera vissa delar av en komplicerad modell och få andra delar att splittras och spridas i en dynamisk simulation som är både fysiskt rätt och ser visuellt bra ut.
