  2. 1. The roles of the plasminogen activator and matrix metalloproteinase systems in ovulation and corpus luteum formation

    Author : Ida Bodén; Umeå universitet; []
    Keywords : ovary; ovulation; corpus luteum; plasminogen; PA; MMP; mouse;

    Abstract : Proteases of the plasminogen activator (PA) and the matrix metalloproteinase (MMP) enzyme systems are expressed in the ovulatory follicle and in the developing corpus luteum (CL). However, the functional role of these extracellular degrading protease systems in the ovulatory and CL development processes remains elusive. READ MORE

  4. 2. On New Implants - The results of five prospective, randomized RSA trials with aspects on phased introduction and continuous migration

    Author : Mats Molt; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; New total knee arthroplasty; TKA; RSA; randomized; prospective; prediction; continuously migrating; safety; stability CR; PS; PF; PA; short stem; tourniquet;

    Abstract : A concern that arises with any change in design or operative technique is whether it affects the long-term implant stability or not. One way to address this is, by measuring early micromotion, to predict the future revision rate. READ MORE

  5. 3. Matrix degrading proteases in the ovary : expression and function

    Author : Patrik Wahlberg; Tor Ny; Ilpo Huhtaniemi; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; ovary; ovulation; corpus luteum; plasminogen; PA; MMP; rat; mouse; Biokemi; Biochemistry; Biokemi; medicinsk biokemi; Medical Biochemistry;

    Abstract : Extracellular matrix degrading proteases from the plasminogen (plg) activator (PA) and the matrix metalloproteinase (MMP) systems have been implicated as important mediators of ovulation and corpus luteum (CL) formation and regression. The aim of this thesis was to investigate the expression and regulation of PAs and MMPs in the ovary and to examine their functional roles for CL formation and function. READ MORE

  6. 4. Reliable and Efficient Microwave Circuits for Space Applications

    Author : Andreas Ådahl; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ZBD; PA; Class E; Zero Bias Diode; LDMOS; Mixer; MMIC; Satellite; Balun; Inverse class F; Novel; Multiplier; mHEMT; Power amplifier; Converter;

    Abstract : In this thesis, reliable and efficient microwave circuits used in space applications, e.g. satellite transponder systems, are discussed. The main focus is on mixers, multipliers and power amplifiers. READ MORE

  7. 5. Epigenetic influence on cardiovascular protective mechanisms in vivo: explorations of t-PA release and extracellular vesicle genetic content

    Author : Kristina Svennerholm; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial ischemia; epigenetics; histone deactylase inhibition; t-PA; extracellular vesicles; ischemic preconditioning;

    Abstract : ABSTRACT Background: Ischemic heart disease is one of the leading causes of death globally. This thesis explores endogenous mechanisms protecting against myocardial ischemia in context of epigenetics (changes in gene activity not caused by changes in DNA sequences). READ MORE
