Evaluation of Serum Paraoxonase, Myeloperoxidase, and HDL-Cholesterol Levels in Acute Myeloid Leukemia.

Inflammation and oxidative stress play a significant role in the pathogenesis of acute myeloid leukemia. While myeloperoxidase carries pro-oxidant effects, HDL-cholesterol and paraoxonase have antioxidant properties. Therefore, we evaluated serum paraoxonase, myeloperoxidase, and HDL-cholesterol levels in cases with acute myeloid leukemia. Myeloperoxidase, paraoxonase, and HDL-cholesterol levels in 40 acute myeloid leukemia patients and 18 healthy individuals were determined. The relationship between these parameters and other prognostic factors, as well as their association with response to chemotherapy, was investigated. Myeloperoxidase levels were higher, while paraoxonase and HDL-cholesterol levels were lower in acute myeloid leukemia cases compared to the control group (p < 0.001, p < 0.001, p = 0.006, respectively). The myeloperoxidase level was significantly negatively correlated with paraoxonase and HDL-c levels (r = - 0.64, p < 0.001; r = - 0.27, p = 0.02, respectively). Paraoxonase level was positively correlated with HDL level (r = 0.34, p = 0.04). Lactate dehydrogenase level was negatively correlated with HDL-c and paraoxonase levels and positively correlated with myeloperoxidase level (r = - 0.37, p = 0.019; r = - 0.35, p = 0.04; r = 0.45, p = 0.03, respectively). Following complete remission induction treatment, cases with complete remission had lower myeloperoxidase levels and higher HDL-cholesterol and paraoxonase levels compared to other cases (p = 0.03, p = 0.01, p = 0.04, respectively). Myeloperoxidase levels are higher, while paraoxonase and HDL-cholesterol levels are lower in acute myeloid leukemia cases. The obtained findings emphasize the potential importance of inflammation and oxidative stress in the pathogenesis of acute myeloid leukemia. These parameters can be used as biomarkers for prognosis prediction and prediction of response to chemotherapy.

Investigation of the Neuro-Regenerative Effects of Bioresonance and Magnetotherapy in Sciatic Nerve Damage-Induced Rats / Investigación de los Efectos Neurorregenerativos de Biorresonancia y Magnetoterapia en Ratas Inducidas por Daño del Nervio Ciático

SUMMARY: Peripheral nerve damage is a significant clinical problem that can lead to severe complications in patients. Regarding the regeneration of peripheral nerves, it is crucial to use experimental animals' nerves and use different evaluation methods. Epineural or perineural suturing is the gold standard in treating sciatic nerve injury, but nerve repair is often unsuccessful. This study aimed to investigate the neuroregenerative effects of magnetotherapy and bioresonance in experimental animals with sciatic nerve damage. In this study, 24 female Wistar rats were divided into 7 groups (n=6) as follows: Group 1 (Control), Group 2 (Axonotmesis control), Group 3 (Anastomosis control), Group 4 (Axonotmesis + magnetotherapy), Group 5 (Anastomosis + magnetotherapy), Group 6 (Axonotmesis + bioresonance), Group 7 (Anastomosis + bioresonance). Magnetotherapy and bioresonance treatments were applied for 12 weeks. Behavioural tests and EMG tests were performed at the end of the 12th week. Then the rats were sacrificed, and a histopathological evaluation was made. The statistical significance level was taken as 5 % in the calculations, and the SPSS (IBM SPSS for Windows, ver.21) statistical package program was used for the calculations. Statistically significant results were obtained in animal behaviour tests, EMG, and pathology groups treated with magnetotherapy. There was no statistically significant difference in the groups treated with bioresonance treatment compared to the control groups. Muscle activity and nerve repair occurred in experimental animals with acute peripheral nerve damage due to 12 weeks of magnetotherapy, and further studies should support these results.

El daño a los nervios periféricos es un problema clínico importante que puede conducir a complicaciones graves en los pacientes. En cuanto a la regeneración de los nervios periféricos, es crucial utilizar los nervios de los animales de experimentación y diferentes métodos de evaluación. La sutura epineural o perineural es el gold estándar en el tratamiento de lesiones del nervio ciático, pero la reparación del nervio a menudo no tiene éxito. Este estudio tuvo como objetivo investigar los efectos neuroregenerativos de la magnetoterapia y la biorresonancia en animales de experimentación con daño del nervio ciático. En el estudio, 24 ratas hembras Wistar se dividieron en 7 grupos (n=6) de la siguiente manera: Grupo 1 (Control), Grupo 2 (Control de axonotmesis), Grupo 3 (Control de anastomosis), Grupo 4 (Axonotmesis + magnetoterapia), Grupo 5 (Anastomosis + magnetoterapia), Grupo 6 (Axonotmesis + biorresonancia), Grupo 7 (Anastomosis + biorresonancia). Se aplicaron durante 12 semanas tratamientos de magnetoterapia y biorresonancia. Las pruebas de comportamiento y las pruebas de EMG se realizaron al final de la semana 12. Luego se sacrificaron las ratas y se realizó una evaluación histopatológica. El nivel de significación estadística se tomó como 5 % en los cálculos, y se utilizó el programa de paquete estadístico SPSS (IBM SPSS para Windows, ver.21). Se obtuvieron resultados estadísticamente significativos en pruebas de comportamiento animal, EMG y grupos de patología tratados con magnetoterapia. No hubo diferencia estadísticamente significativa en los grupos con tratamiento de biorresonancia en comparación con los grupos controles. La actividad muscular y la reparación nerviosa, se produjeron en animales de experimentación con daño nervioso periférico agudo, debido a 12 semanas de magnetoterapia.Estudios adicionales deberían respaldar estos resultados.

Serum Copper and Zinc Levels in Primary Immune Thrombocytopenia.

Although the pathogenesis of immune thrombocytopenia is not fully known, oxidative stress is one of the etiological causes. Copper and zinc are elements in the antioxidant system, and their deficiency causes oxidative stress. We aimed to determine the serum copper and zinc levels and their effects on the response to treatment in patients with immune thrombocytopenia. We analyzed 51 patients with primary immune thrombocytopenia and 33 control cases. Age, gender, and platelet values at the time of diagnosis, drugs used for the treatment of immune thrombocytopenia, remission status, and serum copper and zinc levels were recorded. The primary immune thrombocytopenia and control groups were compared in terms of serum copper and zinc levels. In addition, the relationship between the response status to the treatment of patients with immune thrombocytopenia and serum copper and zinc levels was investigated. The serum zinc level in the immune thrombocytopenia group and control group was 10.35 ± 3.28 µmol/L and 12.82 ± 2.41 µmol/L, respectively (p = 0.01). The serum copper level in patients with immune thrombocytopenia (77.3 ± 22.23 µg/dL) was significantly lower than the control group (99.4 ± 20.82 µg/dL) (p = 0.01). A significant correlation was found between the response to first-line treatment of primary immune thrombocytopenia and serum copper level (p = 0.005). The serum copper level was significantly lower in relapsed cases (p = 0.001). In conclusion, serum copper and zinc levels are lower in patients with primary immune thrombocytopenia than in healthy cases. Patients with relapsed or unresponsive to immune thrombocytopenia treatment have lower serum copper levels than other patients.

Development and Validation of a Turkish Hypnotic Suggestibility Scale.

OBJECTIVE: To construct a scale for testing hypnotic suggestibility for Turkish-speaking adults that may be quick and convenient, and to test its reliability and validity. METHODS: The study was conducted at the hypnotherapy outpatient clinics of Atatürk University Acupuncture and Complementary Medicine Application and Research Centre. Erzurum, Turkey, from June to August 2017, and comprised aged 18-60 years. As the first step in the preparation of the scale, a panel of 15 experts was founded. The draft was pilot-tested. Incomprehensible suggestion templates in the pilot study were abolished, and the templates were reduced to four which were put to test as the Tastan Suggestibility Scale. Stanford Hypnotic Clinic Scale was also used on the same subjects, and the results were analysed using SPSS. . RESULTS: Of the 61 subjects, 38(62.3%) were females and 23(37.7%) were males. The overall mean age was 34.21±9.9 years. Cronbach alpha internal reliability coefficient of the scale was calculated to be 0.53. Correlation between the Tastan Suggestibility Scale and Stanford Hypnotic Clinic Scale total scores was high (p<0.001). Mean duration of the application of the scale was 5.0±1.2 minutes. CONCLUSIONS: Tastan Suggestibility Scale was found to be a new, reliable, and rapidly applicable scale.
