AB  - Objective: To evaluate an association between bone levels of inflammation/oxidative stress mediators and postoperative discomfort after third molar conventional or piezosurgery. Material and methods: Twenty-six subjects with bilaterally impacted mandibular third molars, who underwent either piezo or conventional surgery, were included in a split-mouth design study. MicroRNA-21 (miR-21) expression, interleukin-1 beta (IL-1β), and vascular endothelial growth factor (VEGF) proteins, as well as superoxide dismutase (SOD) activity in alveolar bone, were evaluated. Pain intensity, the first pain appearance, analgesic first use and total dose taken, trismus, and swelling were clinically recorded. Results: MiR-21 expression was higher while VEGF protein was lower in piezosurgery vs. conventional groups. The differences in IL-1β protein and SOD activity were not significant between groups. The pain intensity on the first day was significantly decreased in piezosurgery group. The first pain appearance and the first analgesic taken were reported sooner in conventional vs. piezosurgical group. Significantly pronounced trismus on the third day following conventional surgery was found. In conventional group, significantly increased trismus was observed on the third compared to the first postoperative day. MiR-21 showed significant correlation with the first pain appearance. Conclusion: Delayed onset of less pronounced postoperative pain after piezosurgical vs. conventional extraction of impacted lower third molar was significantly associated with expression of bone miR-21. Clinical relevance: Alveolar bone miR-21 may reflect surgical stress and is associated with third molar postoperative pain onset.

AB  - Introduction: Nearly sixty percent of patients with prostate cancer (PCa) undergo radiation therapy (RT). During the course of treatment patients may experience normal tissue reactions. It is a well established fact that genetic and epigenetic mechanisms, such as microRNA (miRNA) level changes might be associated with radiotoxicity, as a response to irradiation. 
Materials and methods: This is the first study that has investigated levels of radiosensory miRNAs in association with acute genitourinary radiotoxicity extracted from peripheral blood mononuclear cells (PBCs), in three points; before RT (BRT), after RT (ART) and on the first control examination (FCONT). We measured levels of miR-21/146a/155 expression by quantitative real-time PCR (qRT-PCR), comparative ΔΔCt method, in fifteen patients with localized prostate cancer, treated with three-dimensional conformal radiotherapy (3DCRT). Nine subjects have experienced acute genitourinary (GU) radiotoxicity whereas six where without GU radiotoxicity. 
Results: Firstly, we detected the highest levels of miR-21 in ART group (p = 0.043) in the patients with acute GU radiotoxicity. Secondly, we found trend towards higher miR-21 levels and significantly higher levels of miR-146a/155 within the patients with acute GU toxicity than in patients without (p = 0.068, p = 0.016, and p = 0.010, respectively). Thirdly, we detected significant change in miR-146a/155 levels within the patients without acute GU radiotoxicity during RT p = 0.042, and p = 0.041, respectively). 
Conclusion: miR-21/146a/155 might be useful potential factors of radiosensitivity and acute genitourinary radiotoxicity in prostate cancer patients. miRNA might have great potential as predictors of various pathological conditions extracted from PBMCs.

AB  - Objective: Leukocyte- and platelet-rich fibrin (L-PRF) represents a natural, low-cost product which may promote tissue healing by mechanisms not fully elucidated. Diabetes mellitus (DM) disrupts bone healing by inducing inflammation and oxidative stress (OS), mechanisms regulated by microRNAs (miRs). The aim of the present study was to investigate the microRNA-21 (miR-21) involvement in diabetic bone regeneration using L-PRF alone or in combination with a standard grafting material. Design: After the induction of diabetes (alloxan 100 mg/kg), four cranial osteotomies were made in diabetic (n = 12) and non-diabetic (n = 12) rabbits: one was left empty and the remaining three were grafted with L-PRF, bovine hydroxyapatite (Bio-Oss((R))) and L-PRF + Bio-Oss((R)). Two and eight weeks postoperatively, the samples were harvested for miR-21 expression (Real-time RT-PCR) and enzyme-linked immunosorbent assay analyses. Results: Diabetic rabbits showed decreased miR-21 and matrix metalloproteinase-9 (MMP-9) protein expression while increased malondialdehyde (MDA) levels two weeks postoperatively; however, there were no significant differences in miR-21 and MMP-9 levels between diabetic and non-diabetic rabbits in samples taken eight weeks postoperatively. Application of L-PRF and L-PRF + Bio-Oss((R)) improved miR-21 and MMP-9 and decreased MDA levels while Bio-Oss((R)) alone enhanced superoxide dismutase (SOD) activity levels in diabetic rabbits. Conclusion: L-PRF alone or in combination with bovine hydroxyapatite as bone graft could be beneficial in DM since it seems to improve inflammation-modulatory miR-21 expression and decreases oxidative stress.

AB  - AimRecent studies point at the crucial role of epigenetic mechanisms in the development of multifactorial diseases such as periodontitis and diabetes mellitus (DM) type 2. In addition, circulatory microRNAs (miRs) have emerged as novel biomarkers for various diseases. Aim of this study was to investigate the levels of miR-146a and miR-155 and superoxide dismutase (SOD) activity in gingival crevicular fluid (GCF) of periodontitis patients with (CPDM) and without (CP) DM type 2 as well as in periodontally healthy, control groups (PHDM and PH, respectively). Material and methodsmiR modulation was analysed using quantitative real-time PCR while SOD activity was measured spectrophotometrically. ResultsThe upregulation of miR-146a and miR-155 was observed in CP and CPDM patients' baseline, while the levels decreased after 6weeks of the non-surgical therapy to the levels comparable to PH and PHDM, respectively. Expression levels of miRs positively correlated with SOD activity. Levels of miR-146a were higher in PHDM compared to PH patients. Multivariate analysis revealed that levels of miR-146a and miR-155 were significantly associated with periodontitis when adjusting for age and gender. ConclusionsmiR-146a and miR-155 may be considered as possible novel biomarkers for periodontitis in non-diabetic and type 2 diabetic patients.

AB  - AimRecent studies point at the crucial role of epigenetic mechanisms in the development of multifactorial diseases such as periodontitis and diabetes mellitus (DM) type 2. In addition, circulatory microRNAs (miRs) have emerged as novel biomarkers for various diseases. Aim of this study was to investigate the levels of miR-146a and miR-155 and superoxide dismutase (SOD) activity in gingival crevicular fluid (GCF) of periodontitis patients with (CPDM) and without (CP) DM type 2 as well as in periodontally healthy, control groups (PHDM and PH, respectively). Material and methodsmiR modulation was analysed using quantitative real-time PCR while SOD activity was measured spectrophotometrically. ResultsThe upregulation of miR-146a and miR-155 was observed in CP and CPDM patients' baseline, while the levels decreased after 6weeks of the non-surgical therapy to the levels comparable to PH and PHDM, respectively. Expression levels of miRs positively correlated with SOD activity. Levels of miR-146a were higher in PHDM compared to PH patients. Multivariate analysis revealed that levels of miR-146a and miR-155 were significantly associated with periodontitis when adjusting for age and gender. ConclusionsmiR-146a and miR-155 may be considered as possible novel biomarkers for periodontitis in non-diabetic and type 2 diabetic patients.

AB  - Breast cancer (BC) is a heterogeneous group of diseases that still represents a major cause of death in the female population. MicroRNAs (miRNAs, miRs), such as miR-221 and miR-222, have been shown to be involved in BC pathology by acting via its target genes such as tissue inhibitor of metalloproteinase 3 (TIMP3). The main goals of this study were to find differences in miR-221/222 levels of expression in BC groups based on invasiveness, and to investigate the association with estrogen receptor (ER), TIMP3 messenger RNA (mRNA) levels, and clinicopathological characteristics of patients and tumors. In this study, we measured levels of miR-221/222 in 63 breast tissue samples by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) using TaqMan(A (R)) technology and immunohistochemistry. miR-221/222 levels varied significantly across groups based on invasiveness (P  lt  0.001). In in situ tumors, miR-221 and miR-222 were negatively associated with ER (P = 0.001, r = -0.714, and P = 0.013, r = -0.585, respectively). In invasive breast carcinomas associated with non-invasive tumors, miR-222 was inversely associated with ER (P = 0.039, r = -0.620). Pure invasive BCs showed a positive correlation of miR-221 and miR-222 with TIMP3 mRNA levels (P = 0.008, r = 0.508, and P = 0.010, r = 0.497, respectively). An increase in miR-221/222 might be an important event for in situ carcinoma formation, and miR-221/222 may be important molecules that highlight potential differences between invasive breast carcinomas associated with non-invasive and pure invasive BCs.

AB  - Invasive ductal carcinomas with a non-invasive component (IDC-DCIS) are classified as a group of invasive breast carcinomas, together with pure invasive ductal carcinomas of the breast (IDC). MicroRNA-21 (miR-21) has been characterized as a factor of breast cancer invasiveness, however the difference in miR-21 expression levels between IDC-DCIS and pure IDC tumors and the correlations with standard diagnostic and prognostic parameters inside the IDC-DCIS group are unknown. Our aim was to determine if miR-21 had the ability to distinguish these two invasive breast cancer groups. Levels of miR-21 expression were measured by a stem-loop quantitative Real-Time PCR (RT-qPCR) method. Expression levels of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (Her-2) and proliferative index Ki-67 were evaluated by immunohistochemistry. IDC-DCIS tumors had significantly lower levels of miR-21 expression in grade 2 (P=0.003, Mann-Whitney U test), ER positive (P=0.025, Mann-Whitney U test) and PR positive tumors (P=0.024, Mann-Whitney U test) than pure IDCs. miR-21 levels showed a different pattern of expression in IDC-DCIS compared to IDC tumors, which is based on the difference in miR-21 expression between Her-2 negative and Her-2 positive IDC-DCIS tumors (P=0.030, Mann-Whitney U test) and high negative correlation of miR-21 levels with PR levels (rho=-0.886, P=0.006, Spearman correlation). According to our results, IDC-DCIS breast carcinomas act in a different manner in pure IDC tumors with regard to the relations between miR-21 expression levels and the standard diagnostic and prognostic parameters, such as Her-2 status, ER and PR status and protein levels.

AB  - MicroRNAs play essential role in breast carcinoma progression and invasion. Our principal goals were to assess clinicopathological and prognostic correlations of microRNA-21 (miR-21) expression levels in a group of 39 Serbian breast cancer patients with invasive lobular (ILC), ductal (IDC), or mixed (ILC-IDC) breast carcinomas and in order to discover the role of miR-21 in potential novel form of stratification of the patients with different estrogen receptor (ER) and progesterone receptor (PR) status. MiR-21 expression levels were measured by stem-loop real-time RT-PCR using TaqMan technology. ER, PR, human epidermal growth factor 2 receptor (Her-2), and proliferative index (Ki-67) were evaluated by immunohistochemistry. MiR-21 levels do not vary among ILC, IDC, and ILC-IDC subgroups. MiR-21 expression levels varied significantly in the age, tumor size, Ki-67, and different grade (p = 0.030, p = 0.036, p = 0.027 and p = 0.032, respectively) subgroups. ER? and PR? showed higher miR-21 levels than their negative receptor status paired groups ER-and PR-with p = 0.012 and p = 0.018, respectively. MiR-21 positively correlated with ER and PR status (p = 0.018, rho = 0.379 and p = 0.034, rho = 0.345, respectively). Our findings suggest that miR-21 emulates transitional form of expression and that the levels of expression might be useful for stratification of the patients with different receptor status with the purpose to seek for new therapy approaches especially for the patients with the lack of response to conventional endocrine therapy.

AB  - Background/Aim. Atherosclerotic-occlusive changes could be observed in orofacial branches of the external carotid artery. Atherosclerosis-induced ischemia caused alteration in production and release of endothelial factors. The aim of this study was to investigate the influence of carotid artery occlusion (10, 30 and 60 min) on vascular effects of norepinephrine (NOR) and neuropeptide Y (NPY) in the isolated glandular branch of the rabbit facial artery, the main feeding artery for the submandibular gland. Method. Changes in isometric tension were recorded in organ bath studies with arterial rings, before and after carotid artery occlusion. Results. Concentrationdependent vasocontractile effect of NOR was significantly augmented after 30 and 60 min of carotid occlusion, but only in the rings with intact endothelium. Given alone, NPY showed no effect in isolated glandular branch of the rabbit facial artery, but enhanced NOR vasoconstriction in all the investigated rings. NOR vasocontractile effect enhancement in the presence of NPY was attenuated after 30 and 60 min of carotid occlusion. Also, enhancement of NOR vasoconstriction by NPY was significantly higher in endothelium-intact rings compared to endotheliumdenuded rings obtained after 30 and 60 min of carotid occlusion. Conclusion. The present investigation provides results of increased vasocontractile effect of NOR and decreased enhancing effect of NPY on NOR vasoconstriction in the rabbit facial artery after carotid occlusion that is related to altered endothelium function.

Ishemija izazvana aterosklerozom, dovodi do poremećaja stvaranja i oslobađanja faktora poreklom iz endotela. Cilj ovog istraživanja bio je da se ispita uticaj okluzije karotidne arterije (10, 30 i 60 min) na vazokontraktilne efekte norepinefrina (NOR) i neuropeptida Y (NPY) na izolovanoj žlezdanoj grani facijalne arterije kunića, glavne dovodne arterije za submandibularnu žlezdu. Metode. U kupatilu za izolovane krvne sudove ispitivane su izometrijske promene tonusa arterijskih preparata, pre i posle okluzije karotidne arterije. Rezultati. Koncentracijski-zavisan vazokontraktilni efekat NOR bio je značajno veći posle 30 i 60 min karotidne okluzije, ali samo na preparatima sa očuvanim endotelom. Primenjen u rastućim koncentracijama, NPY nije imao efekta na tonus izolovane žlezdane grane facijalne aterije kunića, ali je povećao vazokontraktilni efekat NOR na svim ispitivanim preparatima. Povećanje vazokontraktilnog efekta NOR u prisustvu NPY bilo je značajno manje posle 30 i 60 min okluzije. Takođe, efekat NPY posle karotidne okluzije bio je značajno veći na preparatima sa očuvanim endotelom u odnosu na preparate sa uklonjenim endotelom. Zaključak. Ovo istraživanje pokazalo je povećanje vazokontraktilnog efekta NOR i smanjenje potencirajućeg efekta NPY na vazokonstrikciju izazvanu NOR na facijalnoj arteriji kunića posle okluzije karotidne arterije koje su povezane sa promenjenom funkcijom endotela.

Cilj ovog istraživanja bio je da se ispita uticaj okluzije karotidne arterije (10, 30 i 60 min) na vazokontraktilne efekte norepinefrina (NOR) i neuropeptida Y (NPY) na izolovanoj žlezdanoj grani facijalne arterije kunića, glavne dovodne arterije za submandibularnu žlezdu. Metode. U kupatilu za izolovane krvne sudove ispitivane su izometrijske promene tonusa arterijskih preparata, pre i posle okluzije karotidne arterije. Rezultati. Koncentracijski-zavisan vazokontraktilni efekat NOR bio je značajno veći posle 30 i 60 min karotidne okluzije, ali samo na preparatima sa očuvanim endotelom. Primenjen u rastućim koncentracijama, NPY nije imao efekta na tonus izolovane žlezdane grane facijalne aterije kunića, ali je povećao vazokontraktilni efekat NOR na svim ispitivanim preparatima. Povećanje vazokontraktilnog efekta NOR u prisustvu NPY bilo je značajno manje posle 30 i 60 min okluzije. Takođe, efekat NPY posle karotidne okluzije bio je značajno veći na preparatima sa očuvanim endotelom u odnosu na preparate sa uklonjenim endotelom. Zaključak. Ovo istraživanje pokazalo je povećanje vazokontraktilnog efekta NOR i smanjenje potencirajućeg efekta NPY na vazokonstrikciju izazvanu NOR na facijalnoj arteriji kunića posle okluzije karotidne arterije koje su povezane sa promenjenom funkcijom endotela.",

AB  - MicroRNA-21 (miR-21) overexpression is characteristic for various types of tumors, but it is still unknown whether its expression levels differ between invasive and non-invasive breast carcinomas. The main goal of the study was to determine the difference in miR-21 expression among normal tissue, non-invasive, invasive with non-invasive component, and pure invasive breast cancer samples, to explain its potential role and significance in breast cancer invasiveness. The second goal was to propose miR-21 as molecular marker of breast cancer invasiveness and potential target for future anti-miR therapies for the prevention of invasion and metastasis. In order to reveal the role of miR-21 in breast cancer invasiveness, we measured miR-21 expression levels in 44 breast cancer and four normal samples by stem-loop real-time RT-PCR using TaqMan technology. Relative expression levels of miR-21 were significantly higher in invasive than in other groups (P = 0.002) and significantly higher in invasive compared with invasive with non-invasive component group in histological (P = 0.043) and nuclear grade 2 (P = 0.036), estrogen-receptor-positive (ER+) (P = 0.006), progesterone-receptor-positive (PR+) (P = 0.008), ER+ PR+ (P = 0.007), and proliferation index (Ki-67)  lt = 20 % (P = 0.036) tumors. Our findings suggest that miR-21 could be independent molecular marker of breast cancer invasiveness and potential target for future anti-miR therapies for the prevention of invasion and metastasis.

AB  - The aim of this study was to assess the effect of type 1 diabetes mellitus (induced by a single intravenous injection of 100 mg kg(-1) of alloxan) on acetylcholine (ACh)-induced relaxation in isolated rabbit parotid gland feeding artery. Isometric force measurements and quantification of inducible nitric oxide synthase (iNOS) mRNA by real-time RT-PCR were made in parotid artery rings from diabetic and control rabbits. Acetylcholine induced concentration- and endothelium-dependent vasorelaxation that was significantly decreased in parotid artery rings from diabetic rabbits. Schild analysis of the ACh vasorelaxant effect, in the presence of selective muscarinic receptor antagonists, revealed involvement of the M-3 receptor subtype in parotid artery rings from both control and diabetic rabbits, with no change in antagonist affinity constants. The inhibitory effects of indomethacin, a non-selective inhibitor of cyclooxygenase, and of high potassium, an inhibitor of hyperpolarization, on ACh vasorelaxation were increased. The effect of N-G-nitro-L-arginine, a non-selective inhibitor of NOS, was decreased in diabetes. S-methylisothiourea, a selective inhibitor of iNOS, significantly reduced ACh vasorelaxation only in parotid artery rings from diabetic rabbits. Also, up-regulation of iNOS mRNA expression was detected in parotid artery rings from diabetic rabbits. These results suggest that in parotid artery rings from diabetic rabbits, impaired endothelium-dependent vasorelaxation to ACh appears to be caused by the loss of a nitric oxide-mediated component and increased iNOS expression, and is unlikely to be caused by a change at the M-3 receptor level.
