    The effect of simvastatin on serum cytokine levels and bone metabolism in postmenopausal subjects: Negative correlation between TNF-α, and anabolic bone parameters
    (Springer Japan, 2004) Tikiz C.; Ünlü Z.; Tikiz H.; Ay K.; Angin A.; Onur E.; Var A.; Tüzün Ç.
    In this prospective study, we aimed to evaluate the effect of simvastatin on bone metabolism and the correlation between changes in bone turnover parameters and serum cytokine levels. For this purpose, 38 postmenopausal subjects with hypercholesterolemia (>240mg/dl), not on osteoporosis treatment, were studied. Simvastatin was started at a dose of 20mg daily and continued for 3 months. Six patients were excluded from the study during the follow-up period. Pre- and post-treatment samples were analyzed for bone alkaline phosphatase (BAP) and osteocalcin (OCL), as markers of bone formation; for carboxyterminal telopeptide of collagen I (CTX), as a marker of bone resorption; and for interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) cytokine levels. Total cholesterol level was decreased from 262.1 ± 30.9 to 210.2 ± 35.6mg/dl after simvastatin treatment (P < 0.0001). While no significant change was observed in serum CTX level, BAP and OCL levels were significantly increased (from 120.8 ± 56.6 to 149.5 ± 57.6 IU/I [P = 0.008], and from 20.8 ± 12.6 to 34.7 ± 18.4 μg/l [P = 0.015], respectively). In the analysis of cytokines, while no significant change was observed in IL-6 levels, the TNF-α level was found to be significantly decreased after simvastatin treatment (from 77.9 ± 31.6 pg/ml to 23.5 ± 12.6 pg/ml [P = 0.021]). Individual changes in TNF-α levels showed a moderate negative correlation with the individual changes in BAP and OCL levels (r = -0.550 [P = 0.001], and r = -0.497 [P = 0.004], respectively). In conclusion; 20-mg daily simvastatin treatment for 3 months significantly increased BAP and OCL levels (markers of bone formation) in hypercholesterolemic postmenopausal subjects, without affecting bone resorption. These findings support the idea that simvastatin has an anabolic effect on bone formation. Additionally, the presence of a negative correlation between TNF-α levels and the anabolic bone parameters suggests that a cytokine-lowering effect of simvastatin may also be involved in the remodeling process and could exert some additive beneficial effect on bone metabolism.

    Magnetic resonance imaging findings in a case of remitting seronegative symmetrical synovitis with pitting edema
    (2005) Unlu Z.; Orguc S.; Ovali G.Y.; Tarhan S.; Dayan I.; Angin A.
    We describe a case of remitting seronegative symmetrical synovitis with pitting edema (RS3PE syndrome) in a 66-year-old man. This report discusses magnetic resonance imaging findings of RS3PE syndrome and the changes after steroid therapy. © Clinical Rheumatology 2005.

    Low-Level Laser Therapy is More Effective Than Pulse Ultrasound Treatment onWound Healing: Comperative Experimental Study; [Düşükenerji seviyeli laser tedavisi yara iyileşmesinde kesikli ultrason tedavisinden daha etkindir: Karşılaştırmalı deneysel çalışma]
    (Turkiye Klinikleri, 2010) Tikiz C.; Angin A.; Demireli P.; Taneli F.; Özyurt B.; Tüzün C.
    Objective: To investigate and compare the effects of pulse ultrasound (US) and low-level laser therapy (LLLT) on wound healing. Material and Methods: Thirty-two rats were included in the study and two full-thickness skin wounds were made on dorsum area of the rats bilaterally, with a 17 mm hole-punch. The animals were divided into two groups. Pulsed US (with a power of 0.1 W/cm2, a frequency of 1 MHz, 5 minutes daily) was applied to to the right sided wounds of Group A (n= 16) and Ga-As laser (830 nm wavelength, 0.5 J/ cm2 dosage of 1 MHz frequency for 1 minute duration) was applied to right sided wounds of Group B (n= 16). Left sided wound were considered as controls and same procedures were applied without any current (sham). Biochemical and histopathological evaluations were performed in each group on 7th and 15th days. Results: Inflammatory cells tended to decrease in both treatment groups on the 7th day, however, this finding did not reach a statistical significance (p> 0.05). Fibroblasts and collagen were found to be significantly increased in the laser group when compared to the other group on the 7th day (p< 0.05). Angiogenesis was found to be significantly increased only in the laser group when compared to the other group on the 15th day (p< 0.05). There were no significant differences in tissue nitric oxide values between the groups although the values in the laser group tended to be higher on the 15th day (p=0.058) Conclusion: In this comparative study, LLLT was found to significantly accelerate mainly proliferative phase while pulse US had no effect on wound healing. Our results support the consideration that LLLT may constitute a beneficial treatment modality for wound healing.

    Prognostic Value of Serum Neuron Specific Enolase and Pentraxin-3 In Acute Pulmonary Embolism
    (Yuzuncu Yil Universitesi Tip Fakultesi, 2023) Şaşmaz M.İ.; Tulay C.M.; Gurmen E.S.; Angin A.; Ulman C.
    The aim of this study is to investigate whether serum neuron-specific enolase (NSE) and pentraxin-3 (PTX-3) values are effective in the diagnosis and prognosis of acute pulmonary embolism. In addition, in the light of significant results, we aimed to determine a cut-off value for NSE and PTX-3 in acute pulmonary embolism and to try to determine the sensitivity-specificity in the diagnosis of pulmonary embolism according to these values. In this prospective study, patients who applied to the Emergency Department of Manisa Celal Bayar University School of Medicine between September 2019 and January 2021 and were diagnosed with acute pulmonary embolism constituted the study group and healthy volunteers without any chronic disease or drug use constituted the control group. Serum NSE and PTX-3 values of the patient and control groups were compared. In addition, demographic data, vital signs, laboratory findings, PESI (pulmonary embolism severity index) scores and prognoses of the patients were investigated. In this study 70 patients diagnosed with pulmonary embolism were included to the patient group. 36 (51.4%) of them were women and the mean age was 67.01 ± 14. 74 healthy volunteers were included to the control group; 45 of them (60.8%) were women and the mean age was 44.99 ± 12.85. In patient group the mean PTX-3 value of the was 1.753±1.91 ng/ml, the mean NSE value was 182.13±14.99 ng/ml. In control group, the mean PTX-3 value was 0.429±0.035 ng/ml, the mean NSE value was 166.51±5.14 ng/ml. While there was a statistical difference between two groups in terms of pentraxin-3 value, there was no difference in terms of NSE value. When the cut-off value of 1.115 ng/ml for serum pentraxin-3 in the ROC analysis in order to distunguish the patients with pulmonary embolism from the control group, sensitivity was found to be 58.6% and specificity to be 96%. In our study, we found that serum PTX-3 level is a powerful biomarker with high specificity in the diagnosis of acute pulmonary embolism and is positively associated with the severity and prognosis of the disease. Therefore, we believe that serum PTX-3 may be a guiding biomarker in the diagnosis and prognosis of acute pulmonary embolism in clinical practice. © 2023, Yuzuncu Yil Universitesi Tip Fakultesi.
