Abstract
In the inflamed uterus, the production and secretion of prostaglandins (PGs) and noradrenergic innervation pattern are changed. Receptor-based control of prostaglandin E2 (PGE2) production and secretion by noradrenaline during uterine inflammation is unknown. The aim of this study was to determine the role of α1-, α2- and β-adrenoreceptors (ARs) in noradrenaline-influenced PG-endoperoxidase synthase-2 (PTGS-2) and microsomal PTGE synthase-1 (mPTGES-1) protein levels in the inflamed pig endometrium, and in the secretion of PGE2 from this tissue. E. coli suspension (E. coli group) or saline (CON group) was injected into the uterine horns. Eight days later, severe acute endometritis developed in the E. coli group. Endometrial explants were incubated with noradrenaline and/or α1-, α2- and β-AR antagonists. In the CON group, noradrenaline did not significantly change PTGS-2 and mPTGES-1 protein expression and increased PGE2 secretion compared to the control values (untreated tissue). In the E. coli group, both enzyme expression and PGE2 release were stimulated by noradrenaline, and these values were higher versus the CON group. The antagonists of α1- and α2-AR isoforms and β-AR subtypes do not significantly alter the noradrenaline effect on PTGS-2 and mPTGES-1 protein levels in the CON group, compared to noradrenaline action alone. In this group, α1A-, α2B- and β2-AR antagonists partly eliminated noradrenaline-stimulated PGE2 release. Compared to the noradrenaline effect alone, α1A-, α1B-, α2A-, α2B-, β1-, β2- and β3-AR antagonists together with noradrenaline reduced PTGS-2 protein expression in the E. coli group. Such effects were also exerted in this group by α1A-, α1D-, α2A-, β2- and β3-AR antagonists with noradrenaline on mPTGES-1 protein levels. In the E. coli group, the antagonists of all isoforms of α1-ARs and subtypes of β-ARs as well as α2A-ARs together with noradrenaline decreased PGE2 secretion versus noradrenaline action alone. Summarizing, in the inflamed pig endometrium, α1(A, B)-, α2(A, B)- and β(1, 2, 3)-ARs mediate the noradrenaline stimulatory effect on PTGE-2 protein expression, while noradrenaline via α1(A, D)-, α2A- and β(2, 3)-ARs increases mPTGES-1 protein expression and α1(A, B, D)-, α2A- and β(1, 2, 3)-ARs are involved in PGE2 release. Data suggest that noradrenaline may indirectly affect the processes regulated by PGE2 by influencing its production. Pharmacological modulation of particular AR isoforms/subtypes can be used to change PGE2 synthesis/secretion to alleviate inflammation and improve uterine function.

Abstract
INTRODUCTION AND OBJECTIVES Chronic rhinitis-related complaints may result from isolated hypertrophy of the inferior nasal turbinates. If the symptoms persist despite conservative management, turbinoplasty is indicated. However, the nasal mucosa lining the inferior turbinates seems decongested immediately before the surgery performed under local anaesthesia, compared to the examination when the patients were entered for surgery. The study aimed to confirm this observation and to hypothesize as to the reasons for its occurrence. PATIENTS AND METHODS The measurements of the longest distances between the medial rim of the inferior nasal turbinate mucosa and nasal septum and the shortest distances between the lower rim of the turbinate and floor of the nasal cavity in the inferior part of both common nasal meatus, were carried out on photos taken during endoscopic examinations: the one entering the patient for turbinoplasty, and the other immediately before the procedure. The results in this group were compared to those obtained from patients operated on under general anaesthesia. RESULTS In 130 patients aged 18-60 (mean=40.7) years, operated on under local anaesthesia, the sum of the mean distances between the nasal septum and the medial rim of the lower turbinate in both nasal cavities, was 3.4mm during the first examination, and 4.5mm (p=.0008) during the second one. In the group of 42 participants aged 26-47, mean=36.8 years operated on under general anaesthesia, the values were: 4.8mm and 3.6mm (p=.02), respectively. The differences were significantly smaller in the smokers (.3) compared to non-smokers (1.3; p=.04) mm. CONCLUSIONS Records of the entering examination must be considered before turbinoplasty under local anaesthesia.

Post-Mortem Immunohistochemical Evidence of β2-Adrenergic Receptor Expression in the Adrenal Gland. Int J Mol Sci 2019; 20:ijms20123065.

Abstract
The evidence from post-mortem biochemical studies conducted on cortisol and catecholamines suggest that analysis of the adrenal gland could provide useful information about its role in human pathophysiology and the stress response. Authors designed an immunohistochemical study on the expression of the adrenal β2-adrenergic receptor (β2-AR), a receptor with high-affinity for catecholamines, with the aim to show which zones it is expressed in and how its expression differs in relation to the cause of death. The immunohistochemical study was performed on adrenal glands obtained from 48 forensic autopsies of subjects that died as a result of different pathogenic mechanisms using a mouse monoclonal β2-AR antibody. The results show that immunoreactivity for β2-AR was observed in all adrenal zones. Furthermore, immunoreactivity for β2-AR has shown variation in the localization and intensity of different patterns in relation to the original cause of death. To the best of our knowledge, this is the first study that demonstrates β2-AR expression in the human cortex and provides suggestions on the possible involvement of β2-AR in human cortex hormonal stimulation. In conclusion, the authors provide a possible explanation for the observed differences in expression in relation to the cause of death.

Abstract
The inferior turbinate has well-recognized respiratory and immune functions to provide the airway with appropriate warmth, humidification, and filtration of the inspired air while sampling the environment for pathogens. Normal functioning of the inferior turbinate relies on an intact autonomic system to maintain homeostasis within the nasal cavity. The autonomic nervous system innervates the submucosal glands and the vasculature within the inferior turbinate, resulting in control of major turbinate functions: nasal secretions, nasal patency, warmth, and humidification. This review will summarize the autonomic innervations of the turbinates, both the normal and abnormal autonomic processes that contribute to the turbinate functions, and the clinical considerations regarding optimal functioning of the turbinate autonomic system.

Abstract
Under physiological conditions, noradrenaline (NA) and adrenergic receptors (ARs) are implicated in the function of the uterus. The role of NA and the expression of ARs in the inflamed uterus is not fully understood. The aim of the present study was to determine the effect of inflammation on the levels of α1 (A, B, D)-, α2 (A, B, C)- and β (1, 2, 3)-ARs mRNA and protein expression and the localization of these receptors in the porcine uterus. On Day 3 of the estrous cycle (Day 0 of the study), 50 ml of either saline (group SAL) or E. coli suspension (109 colony-forming units/ml, group E. coli) were injected into each uterine horn. In the control pigs (group CON), only laparotomy was performed. Eight days later, α1D-ARs mRNA (P < 0.001) and protein (P < 0.05) levels and α2A-ARs protein level (P < 0.05) were increased in the inflamed endometrium, while the α2C-ARs protein level (P < 0.001) was lowered, as compared to the SAL and CON groups. In the inflamed endometrium, β2-ARs mRNA (P < 0.01) and protein (CON: P < 0.01, SAL: P < 0.001) expression was lower than in the other two groups, and β1-ARs mRNA (P < 0.001) and protein (P < 0.01) expression was higher compared to the SAL group. After bacterial treatment, α2A- (P < 0.001) and α2B (P < 0.05) -ARs protein levels and β2-ARs mRNA (CON: P < 0.01, SAL: P < 0.05) and protein (CON: P < 0.01, SAL: P < 0.05) expression in myometrium were found to be increased compared to both groups. In turn, in myometrium following E. coli infusion, the α2C-ARs protein level was lower (P < 0.01) than in the CON group. All studied receptors were present in the luminal and glandular epithelium, blood vessels and myometrial muscular cells of the gilt uteri in the E. coli, SAL and CON groups. The data show that inflammation changes the ARs expression in porcine uterus, suggesting their importance in the course/consequences of uterine inflammation. Those affected ARs may constitute a therapeutic target in an inflamed uterus.
