Infectious diseases in any age group can be successfully prevented through immunization. Protection provided through immunization in childhood decreases over the years. Immunization in adulthood is important because of the growing elderly population, chronic diseases, and globalization. Recommendations on this subject are being constantly updated through scientific guidelines. Immunization in adulthood is also important in rheumatology. There is an increased risk not only of infection in rheumatic diseases but also of infections being more severe...

The hormone, melatonin is produced with circadian rhythm by the pineal gland in humans. The melatonin rhythm provides an endogenous synchronizer, modulating e.g. blood pressure, body temperature, cortisol rhythm, sleep-awake-cycle, immune function and anti-oxidative defence. Interestingly, a number of experimental animal studies demonstrate significant dose-dependent anti-nociceptive effects of exogenous melatonin. Similarly, recent experimental- and clinical studies in humans indicate significant analgesic effects...

Non-invasive measurement of cortisol in saliva is of prime importance as it represents a bioavailable neuroendocrine marker for stress. Therefore, in this study, we developed an enzyme immune assay that was suitable for salivary cortisol measurements. For that purpose, rabbit polyclonal antibody was raised against cortisol-3-CMO:BSA conjugate. The test was based on competition of liquid phase cortisol with conjugated cortisol on the solid phase. Primary antibody was used to bind available sites on the conjugate, which was proportional to numbers of cortisol in liquid phase...

Neutrophils are the most abundant leukocytes in human blood circulation and are quickly recruited to inflammatory sites. Priming is a critical event that enhances the phagocytic functionality of neutrophils. Although extensive studies have unveiled the existence and importance of neutrophil priming during infection and injury, means of visualizing this process in vivo have been unavailable. The protocol provided enables monitoring of the dynamic process of neutrophil priming in living animals by combining three methodologies: 1) DsRed reporter signal - used as a measure of priming 2) in vivo neutrophil labeling - achieved by injection of fluorescence-conjugated anti-lymphocyte antigen 6G (Ly6G) monoclonal antibody (mAb) and 3) intravital confocal imaging...

Non-intubated thoracic surgery entails procedures performed through regional anesthesia method in awake or mildly sedated, spontaneously ventilating patients. This method represents advantages for the cardiovascular system, and reduces the orotracheal trauma, postoperative atelectasis, and pneumonia. It also possibly reduces costs. Other theoretical advantages are: easier acceptance of surgery, attenuated stress hormone and immune response, and possibly a better survival in oncological surgery. We show a 34-year-old woman with sever palmar-axillary hyperhidrosis...

The pathophysiology behind radiation cystitis is poorly understood. Here we investigated whether bladder irradiation affects the immune system of the rat urinary bladder. Female rats were sedated and exposed to one single radiation dose of 20 Gy or only sedated (controls) and killed 16 h to 14 days later. Rats were placed in a metabolic cage at 16 h, 3 days, 7 days and 14 days following bladder irradiation. The urinary bladders were harvested and analysed with qPCR, immunohistochemistry and/or Western blot for the expression of interferon (IFN)-γ, interleukin (IL)-1β, IL-2, IL-4, IL-5, IL-6, IL-10, IL-13, nitric oxide synthases (eNOS, iNOS and nNOS), tumour necrosis factor (TNF)-α and toll-like receptor 4 (TLR4)...

Vaccines based on live attenuated viruses are highly effective immunogens in the simian immunodeficiency virus (SIV)/rhesus macaque animal model and offer the possibility of studying correlates of protection against infection with virulent virus. We utilized a tether system for studying, in naive macaques and animals vaccinated with a live-attenuated vaccine, the acute events after challenge with pathogenic SIV. This approach allowed for the frequent sampling of small blood volumes without sedation or restraining of the animals, thus reducing the confounding effect of sampling stress...

BACKGROUND Haloperidol, a tranquilizing agent, is administered both to treat symptoms of psychotic disorders and to sedate agitated and delirious patients. Notably, haloperidol has been suggested to inhibit the immune response through unknown mechanisms. We hypothesized that the sedative modulates the immune response via NF-κB. MATERIAL AND METHODS Using flow cytometry, we analyzed the effects of haloperidol on expression CD80 and CD86 in RAW 264 cells and in primary macrophages derived from bone marrow. Secretion of interleukin (IL)-1β, IL-6, and IL-12 p40 was measured by enzyme-linked immunosorbent assay...

Controversial effects of thalidomide for solid malignancies have been reported. In the present study, we evaluate the effects of thalidomide for transitional cell carcinoma (TCC), the most common type of bladder cancer. Thalidomide precipitates were observed when its DMSO solution was added to the culture medium. No precipitation was found when thalidomide was dissolved in 45% γ-cyclodextrin, and this concentration of γ-cyclodextrin elicited slight cytotoxicity on TCC BFTC905 and primary human urothelial cells...

Anesthetics are known to modulate host immune responses, but separating the variables of surgery from anesthesia when analyzing hospital acquired infections is often difficult. Here, the bacterial pathogen Listeria monocytogenes (Lm) was used to assess the impact of the common anesthetic propofol on host susceptibility to infection. Brief sedation of mice with physiologically relevant concentrations of propofol increased bacterial burdens in target organs by more than 10,000-fold relative to infected control animals...

Atopic Dermatitis (AD), the most common chronic inflammatory skin disease, is characterized by an overactive immune response to a host of environmental allergens and dry, itchy skin. Over the past decade important discoveries have demonstrated that AD develops in part from genetic and/or acquired defects in the skin barrier. Histamine is an aminergic neurotransmitter involved in physiologic and pathologic processes such as pruritus, inflammation, and vascular leak. Enhanced histamine release has been observed in the skin of patients with AD and antihistamines are often prescribed for their sedating and anti-itch properties...

The phenomenon of feta-maternal microchimerisms inspires numerous questions. Many questions remain to be answered regarding this new avenue of genetics. The X and Y chromosomes have been associated with malignancy in different types of human tumors. We aimed to investigate the numerical aberrations of chromosomes X and Y in lung cancer (LC) and bladder cancer (BC) and review recent evidence for possible roles of microchimeric cells (McCs) in these cancers. We carried out cytogenetic analysis of the tumor and blood sampling in 52 cases of people with BC and LC, and also with 30 healthy people...
