1. 1. Physiology-Guided Machine Learning for Improved Reliability of Non-Invasive Assessment of Pulmonary Hypertension

   University essay from Linköpings universitet/Avdelningen för medicinsk teknik

   Author : Frida Hermansson; [2023]
   Keywords : Pulmonary Hypertension; pulmonary hypertension; improving; physiological-guided; machine learning; neural networks; NN; artificial neural networks; non-invasive; PH; tricuspid regurgitation; peak tricuspid regurgitation velocity; tricuspid regurgitation velocity; right ventricular systolic pressure; VGG16; Unet; TR-CNN; CNN; pulmonell hypertension; förbättra; fysiologisk-guidning; neurala nätverk; trikuspidal regurgitation; maximal trikuspidal regurgitation; icke-invasivt;

   Abstract : Diagnosing pulmonary hypertension (PH) with right heart catheterization (RHC) is associated with a risk for complications and high expenses, leading to late diagnoses [1]. Transthoracic echocardiography can be used to assess non-invasive indicators for PH such as right ventricular systolic pressure (RVSP), which can be estimated by combining the peak tricuspid regurgitation velocity (TRV) with the estimated right arterial pressure (RAP).

3. 2. Fysiologiska effekter vid stående och liggande immobilisering av asiatiska och afrikanska elefanter : praktisk utvärdering och litteraturstudie

   University essay from SLU/Dept. of Clinical Sciences

   Author : Tina Jansson; [2023]
   Keywords : afrikansk elefant; alfa2-adrenoceptoragonist; asiatisk elefant; fysiologi; immobilisering; opioid; sedering; xylazin;

   Abstract : Elefanten är världens nu största landlevande däggdjur och alla tre arter som finns är listade som hotade av olika grad. Att immobilisera vilda elefanter är en del av det artbevarande arbetet. Även elefanter i djurparker och så kallade arbetselefanter kan behöva immobiliseras, till exempel för vård eller transporter.

4. 3. Morphological characterization of the muscular ridge in non-crocodilian reptiles

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Wilma Sohlén; [2023]
   Keywords : Adaptation; Anatomy; Function; Haemodynamics; Muscular ridge; Reptiles; Shunting;

   Abstract : The cardiovascular systems in ectothermic reptiles have long been studied and its development represent a transition state between a single- and a double circulation. This literature review focus on the typical-reptilian heart and therefore distinguishes between orders within the class of Reptilia. READ MORE

5. 4. Inflammatory Cell Infiltration and Expression of AT1 and AT2 Receptors in Angiotensin II and High-Salt Diet-Induced Balb/CJ Mice

   University essay from Uppsala universitet/Institutionen för medicinsk cellbiologi

   Author : Avishka Herat; [2023]
   Keywords : ;

   Abstract : Pulmonary oedema and pulmonary hypertension are often associated with heart failure. The Balb/CJ and C57BL/6J mouse strains have been shown to exhibit distinct genetic susceptibilities to heart failure. READ MORE

6. 5. Modeling COPD with a Generalized Linear Mixed Effect Model : Results from the OLIN-study

   University essay from Umeå universitet/Statistik

   Author : Jenny Sjödin; [2022]
   Keywords : ;

   Abstract : The purpose of this thesis is to analyze which factors are associated with physicians’ diagnosis of Chronic Obstructive Pulmonary Disease (COPD) where time is of primary interest. The data that is used in the analysis is from the OLIN studies. READ MORE
