Filter by:Infertility is a common, worldwide problem. In about 20% of couples, the causative agent of infertility cannot be identified after routine diagnostic tests. One of the causes of idiopathic infertility may be implantation disorders. Implantation can take place at a strictly defined moment in the menstrual cycle, when the capacity of the blastocyst to implant is overlapped with readiness for its acceptance by the endometrium, the so-called endometrial receptivity.The time interval in which the endometrium exhibits this property is called the implantation window. The acquisition of receptivity by the endometrium is reflected in cellular and structural changes.The changes taking place at the cellular and molecular levels within the endometrium are compared to processes such as wound healing and degradation of the matrix during the neoplastic process.In considering the role of local inflammation in fertility, it is essential to distinguish between acute and chronic inflammation of moderate or low intensity.The profile of the molecules seen in a given inflammation depends on the severity, duration and mechanisms involved in the inflammation process, as well as the ability of the body's immune system to respond and adapt.IL-18 is a pro-inflammatory cytokine that mediates a type 1 cellular response. In the context of fertilization, IL-18 is a bivalent cytokine. Outside of the implantation window, IL-18 acts as an IFN-gamma inducer and is seen as a detrimental factor in the implantation process. During the implantation window, IL-18 becomes one of the main factors involved in the proper preparation of the spiral arteries. Histamine meets all the criteria of an inflammatory mediator. Histamine expression is also expressed in the endometrium, where it plays the role of a paracrine messenger during embryo decision-making and implantation. Adequate glucose uptake and metabolism are essential for the proper differentiation of the uterine endometrium towards a receptive state that allows the implantation of the embryo. The best described and most abundant glucose transporter in the endometrial stroma is GLUT1. However, there are no data on the role of GLUT4 in undetermined infertility. GLUT4 is one of the better studied transporters because of its major role in whole body glucose homeostasis and the pathogenesis of type II diabetes. Aims:1. Analysis of the level of interleukin 18 and histamine as molecules with a postulated role in the implantation process in the receptive endometrium in women with primary infertility of unknown etiology and comparing it to the group of women with naturally conceived offspring. 2. Assessment of the correlation of the levels of interleukin 18 and histamine in the receptive endometrium and in the blood as an attempt to find a diagnostic useful marker of receptivity. 3. Analysis of GLUT4 level in the receptive endometrium between two groups. Materials and Methods: Patients recruited from among women hospitalized at the CMUJ Gynecological Endocrinology Clinic for hormonal diagnostics. 1. The patient's visit during the implantation window (appropriate time of the cycle determined on the basis of ultrasound ovulation monitoring) 2. Endometrial aspiration biopsy, venous blood collection (5 ml). Preparation of material. 3. Analysis of the collected material.
Lower third molar extraction is one of the most common treatments in oral surgery practice. It is a treatment with inherent complications such as postoperative pain, swelling or trismus. In order to minimize disconfort after extraction, analgesic and anti-inflammatory medication is prescribed. Recently, it is seen that circadian rhythm may play an important role on drugs metabolism, modulating its effect depending on the moment of administration. The aim of the study is to analyze if dosage modification of a Non Steroideal Anti-Inflammatory (ibuprofen) affects on postoperative pain, swelling and open mouth limitation comparing to the normal dosage.
The inflammatory process is the main mechanism in the occurrence of acute postoperative pain. It is also the main risk for the development of acute pain into persistent pain. Inflammation occurs in the process of peripheral sensitization and central sensitization with various inflammatory mediators. Postoperatively, there will be proliferation and activation of microglia and astrocytes which will then activate inflammatory receptors and signaling cascades of neurotransmitters, cytokines, and chemokines. There has been a lot of clinical research evidence that multimodal analgesia can adequately treat acute pain and can prevent the development of acute postoperative pain into persistent pain and chronic postoperative pain, but the molecular mechanisms are not fully understood.
Healthy young adults will complete three trials in a randomized crossover counter-balanced order, including two different loads of resistance exercise and sedentary control. During each trial, blood samples will be collected. The investigators hypothesized that high-load and low-load resistance exercise exert similar metabolic responses.
Healthy young and older adults will complete two trials in a randomized crossover counter-balanced order, including resistance exercise and sedentary control. During each trial, blood samples will be collected. The investigators hypothesized that an acute bout of resistance exercise exert different inflammation responses in young and older adults.
Nonsurgical root canal retreatment may become essential when the initial endodontic treatment fails because of the persistent intracanal or extracanal infections.The aim of this thesis study is to evaluate the effect of ProTaper Universal Retreatment (PTUR), Reciproc blue and XP-endo Finisher R file systems, which are used in the removal of root canal filling materials during retreatment with different motion kinetics on the release of Substance P, Calcitonin Gene-Related Peptide (CGRP), IL-6 and IL-10 inflammatory mediators in the periapical region
Patients undergoing coronary artery bypass graft surgery (CABG) frequently exhibit postoperative bleeding complications which are still a major cause for morbidity and mortality. One major contributing factor is the loss of platelets and impaired platelet function. During cardiopulmonary bypass (CPB) blood comes in close contact with foreign surfaces which induces a series of reactions; especially the complement system as part of the innate immunity is highly activated. Due to the strong crosslink between complement system, platelet function and the plasmatic coagulation it is likely that complement activation during CPB has an impact on the overall process of clot formation. Besides the activation of the complement system there is growing evidence that the occurrence of mitochondrial DNA (mtDNA) during CPB might be related to further platelet activation . Activated platelets may enhance micro-thrombosis leading to organ failure and thereby contributing to postoperative morbidity. One major complication during and after CABG surgery is bleeding requiring transfusion and even reoperation in about 2%- 8% of patients. As bleeding complications increase patient morbidity and mortality, this study is designed to investigate the possible mechanisms of platelet loss during CABG. The hypothesis is that increased complement activation during CPB leads to platelet activation and loss of platelets. Further the degree of complement activation and levels of mtDNA might correlate with postoperative bleeding, transfusion requirements and clinical outcome.
INTRODUCTION: Particle contamination is suggested to have substantial negative effects on health, with candles emitting huge amount of particles, thus being one of the largest contributors to indoor air pollution. Chronic low levels of exposure to indoor particles over time is an important risk factor for the health of the population as a whole and it becomes particularly important for vulnerable groups like people suffering from respiratory diseases such as asthma. AIM: In a randomized controlled cross-over trial the difference in health effects between two candles I) a standard candle and II) a low emission candle modified from the standard candle is studied.
The aim of the present study is to determine the effect of Xanthohumol and Iso-alpha-acids from hops on the immune response of healthy participants.
The aim of this trial is to evaluate the effect of high-dose glucocorticoid on inflammatory response and recovery after emergency laparotomy in participants with intestinal obstruction and perforated viscus. Primary outcome is the reduction of C-reactive protein on postoperative day 1. Secondary outcomes are organ specific complications in the post anaesthesia phase, endothel and inflammatory markers, fluid status, preload dependency, pain, lung function, nausea and mobilization during the first 5 days after surgery, . The investigators hypothesize, that a preoperative single high dose of glucocorticoid reduces systemic inflammatory response after emergency laparotomy.
