Effects of Bioresonance Application in Mice with Depressive-Like Behavior.

We studied the effects of bioresonance application on mice with depressive-like behavior induced by stress. A chronic mild stress model was developed in mice to monitor the effects of bioresonance application. After that, behavioral tests were performed. In the forced swimming test, the animals of the long bioresonance therapy demonstrated shorter group immobility time in comparison with mice of the stress group and stress group without therapy (animals of this group were sacrificed at the same time point as therapy groups in order to reveal a possibility of spontaneously recover in animals after stress without therapy). In the tail suspension test, a decrease in immobility time was observed in the long bioresonance therapy group, stress group, and stress without therapy group. These changes in behavioral test results can indicate that the application of bioresonance in mice can be an effective method of treating depressive-like behavior, but these conclusions should be supported by additional experimental studies and the use of different frequencies.

A New Promising Pathway in Aggressive Prostate Cancer: Treg/mir-let8c/lin28b

Purpose: The progress of prostate cancer entails complex contemporaneous tumor developmental events in diverse stages that they are still yet to be clarified. miRNAs might accompany to balance between regulatory and cytotoxic T cells in tumors. Here, we investigated miRNAs and Regulatory T cell (Treg) marker FOXP3 expressions within prostate cancer spectrum. Methods: Thirty-eight prostate cancer patients enrolled within two groups to the study as having Gleason Score ≤ 7 (Group-1) and ≥ 8 (Group-2) that compared to 19 benign prostate hyperplasia controls. Twelve miRNAs expressions were analyzed by real time PCR from paraffin-embedded prostate tissue samples. Correlations between serum PSA levels, immunohistochemical staining of CD3, CD4, FOXP3 and miRNA expressions were analyzed. Results: In our study, hsa-let7c-3p significantly 1,52 (p=0.018) and 1,84 (p=0.0095) fold down- regulated whereas, miR-141-3p was significantly 2,36 (p=0.0006) and 2,24 (p=0.001) fold upregulated in the prostate cancer patients compared to benign prostate hyperplasia in group 1 and 2, respectively. Only CD4 (p=0.004) and PSA (p<0.001) have statistically significant differences among groups when compared to benign prostate hyperplasia. miR-143-p, miR-221-3p, hsa-let7c-3p and miR-17-3p expressions were significantly correlated with regulatory T cell marker FOXP3 expression. Conclusions: For the first time, we reported significantly altered expression levels of miRNAs (miR-let7c, miR221, miR-146a, miR-141, miR-143, miR17) and correlations between Treg marker FOXP3 in the aggressive prostate cancer patients suggesting that prostate cancer progression might be under the regulation of crosstalk between Tregs and miRNAs (AU)

Kefir alters craniomandibular bone development in rats fed excess dose of high fructose corn syrup.

INTRODUCTION: Dietary high fructose corn syrup (HFCS) is involved in the pathogenesis of oral diseases as well as metabolic diseases. The aim of this study was to investigate the effects of HFCS-feeding on the craniomandibular bone development at an early age and also the potential of milk kefir for preventive treatment. MATERIALS AND METHODS: In this study, Control, Kefir, HFCS, and HFCS plus Kefir groups were formed; kefir was given by gastric gavage, while HFCS (20% beverages) was given in drinking water; for 8 weeks. RESULTS: Based on morphological evaluations, immunohistochemical, and gene expression results, it was clearly determined that excess dose of HFCS consumption decreased osteoblastic activity in craniomandibular bones while increasing osteoclastic activity. However, it has been determined that the intake of kefir with the HFCS-feeding greatly suppresses the effects of HFCS on bone tissues. CONCLUSION: In conclusion, dietary the excess dose of HFCS at an early age has been observed to pose a risk for cranial and mandible bone development. The healing effects of kefir may be a new approach to the treatment via kefir consumption in young's.

Detection of antitumoral effects of quercetin through protein synthesis associated with argyrophilic nucleolar-regulating region.

Quercetin is a natural flavonoid with potential anticancer properties without significant cytotoxicity in normal tissues. However, the effects of quercetin on Ehrlich ascites carcinoma (EAC) have not yet been clarified. The study aimed to show the antitumoral effect of quercetin through argyrophilic nucleolar organizer region (AgNOR) protein synthesis in mice carrying EAC. Thirty mice were used in the experiment (negative control (n = 6), tumor control (n = 8), quercetin 50 mg/kg (n = 8), and quercetin 100 mg/kg (n = 8) intravenously). The animals were euthanized on the 14th day, and the solid tumors were removed. Then, the total AgNOR area/nuclear area (TAA/NA) and average AgNOR number were calculated for each mice and the immunoreactivity of the factor VIII protein in tumor was evaluated. Tumor volumes and animal weights were statistically significant compared to the tumor control group (p < 0.05). Statistically significant differences were observed between the groups in terms of TAA/NA ratio (p < 0.05). Factor VIII expressions decreased in quercetin groups compared to control tumor tissue (p < 0.05). The current study showed that quercetin has an important function against cancer development.

The effect of diclofenac sodium on neural tube development in the early stage of chick embryos.

BACKGROUND: Neural tube defects are congenital malformations of the central nervous system. Genetic predisposition and some environmental factors play an important role in the development of neural tube defects. This study aimed to investigate the effects of diclofenac sodium on the neural tube development in a chick embryo model that corresponds to the first month of vertebral deve- lopment in mammals. MATERIALS AND METHODS: Seventy-five fertile, specific pathogen-free eggs were incubated for 28 h and were divided into five groups of 15 eggs each. Diclofenac sodium was administered via the sub-blastodermic route at this stage. Incubation was continued till the end of the 48th h. All eggs were then opened and embryos were dissected from embryonic membranes and evaluated morphologically and histopathologically. RESULTS: It was determined that the use of increasing doses of diclofenac sodium led to defects of midline closure in early chicken embryos. There were statistically significant differences in neural tube positions (open or close) among the groups. In addition; crown-rump length, somite number were significantly decreased in high dose experimental groups compared with control group. CONCLUSIONS: This study showed that development of neurons is affected in chi- cken embryos after administration of diclofenac sodium. The exact teratogenic mechanism of diclofenac sodium is not clear; therefore it should be investigated.

Association between radionuclides (210Po and 210Pb) and antioxidant enzymes in oak (Quercus coccifera) and mastic tree (Pistacia lentiscus).

The activity levels of naturally occurring radionuclides Polonium-210 and lead-210 in different subjects including plant species have direct or indirect impact on human beings. High levels of ionising radiation cause oxidative stress and the interaction between antioxidative defense and radionuclides is not well established in plant systems. In this study, we aimed to understand the impact of oxidative stress caused by 210Po and 210Pb in two Mediterranean plants; Quercus coccifera and Pistacia lentiscus. We analysed the constitutive and seasonal levels of 210Po, 210Pb, lipid peroxidation levels, superoxide dismutase (SOD) and ascorbate peroxidase (APX) activities in the field-collected samples. The highest activity concentrations of 210Po and 210Pb were detected in both plants in summer and Q. coccifera had higher levels than that of P. lentiscus. SOD and APX activity trends were different between oak and mastic; as compared to P. lentiscus, Q. coccifera efficiently used the two major components of antioxidative defense. Lipid peroxidation levels were low in both plants in all seasons except that of spring which were in good agreement with high antioxidant enzyme activities. In conclusion, we found that high 210Po and 210Pb activity concentrations in oak and mastic did not interfere with their growth and life cycles. The ability of both plants for survival and adaptation to Mediterranean environmental constraints provided an additional advantage for coping radionuclide induced oxidative stress as well.

Can rs3767140 SNP of the perlecan (HSPG2) gene affect the diabetes mellitus through the dyslipidemia?

Perlecan (HSPG2) play an important role in the lipoprotein metabolisms. The G allele of the HSPG2-rs3767140 may affect the binding of heparan sulfate (HS) chains and hence cause loss of HS from the basement membrane. HSPG2-rs3767140 was studied in 60 T2DM patients and 109 healthy controls. In diabetic patients HSPG2-rs3767140 T variant allele carriers (TT+GT) have decreased fasting plasma glucose (FPG) and serum LDL-C levels (p=0.071 and p=0.060, respectively) versus GG genotype carriers. Moreover, in both of the two groups in which the T allele carriers HDL-cholesterol levels tend to be high. We investigated that the HSPG2-rs3767140 promoted to the dyslipidemic phenotype in the type 2 diabetes mellitus (T2DM) patients. We suggest that the HSPG2-rs3767140 might be associated with the decreased FPG and LDL-C and with the increased HDL-C in diabetics. Therefore, the HSPG2-rs3767140 might be a protective for the diabetes mellitus due to its ameliorating effect on the dyslipidemic phenotype.

A THANATOPHORIC DYSPLASIA TYPE I CASE WITH A FGFR3 P.R248C MUTATION AND SURVIVAL BEYOND THE NEONATAL PERIOD.

A Thanatophoric dysplasia, is a severe congenital anomaly which mostly causes stillbirth or death of the affected baby within hours due to respiratory insufficiency. The diagnosis of TD is typically suspected on ultrasound during the second trimester of pregnancy, when severe shortening of the long bones, frontal bossing, flattened vertebrae, and short ribs that result in a narrow thorax and bell-shaped abdomen, can be seen. Here, we present a case with prenatal ultrasonographic findings suggestive of TD, and highlight the patient's postnatal dysmorphic features and typical radiographic findings. The definitive diagnosis of TD type I (TDI) was made postnatally, when molecular genetic analysis revealed the previously described p.R248C mutation in FGFR3. This case is reported due to its relative long life span and the definitive molecular diagnosis that could be made during hospitalization.

A mucormycosis case treated with a combination of caspofungin and amphotericin B.

Mucormycosis is a rare, invasive and fatal disease that occurs mainly in diabetes mellitus patients with uncontrolled blood glucose levels or in immunocompromised patients. The mortality rate of this disease is as high as 25 to 80%, despite aggressive surgical treatment and antifungal therapy. This high mortality requires alternative treatment approaches. The accepted treatment modality of invasive mucormycosis are amphotericin B lipid formulations. Although echinocandins generally show no activity against Mucorales, it was shown that Rhizopus oryzae expressed the target enzyme for echinocandins, 1,3-beta-glucan synthase. Additionally, there are some experimental studies in a diabetic mouse model and case reports regarding the effects of caspofungin. In this report, we present a rhinocerebral mucormycosis case treated with liposomal amphotericin B and caspofungin. There was regression of the patient's clinical and radiological condition with the addition of caspofungin, but she died due to discontinuation of her treatment and reasons other than mucormycosis.

Ovarian cryopreservation.

Cryopreservation of ovarian tissue and future autotransplantation are new promising strategies for fertility preservation in various malignant and non-malignant diseases facing the risk of ovarian failure. Ovarian cortrical tissue pieces or intact whole ovary can be removed by laparoscopy without any significant delay in chemotherapy. Slow freezing and vitrification methods are developed to avoid damage to follicles. Ovarian tissue can be transplanted in an orthotopic or heterotopic location when the patient is cured from the disease. Autotransplantation can be performed if absence of malignant cells in the graft is confirmed. Although the procedures are still experimental, ovarian cryopreservation is the single option in prepubertal girls who have not sexual maturity. Earlier team approach of oncologists and reproductive endocrinologists may provide a more successful and professional way of fertility preservation.

Accurate time-dependent wave packet study of the Li + H2⁺ reaction and its isotopic variants.

The dynamics and kinetics of the Li + H2⁺ reaction and its isotopic variants (D2⁺ and T2⁺) have been studied by using a time-dependent wave packet (TDWP) coupled-channel (CC) method on the ab initio potential energy surface (PES) of Martinazzo et al. [J. Chem. Phys. 2003, 119, 21]. Total initial v = 0, j = 0 state-selected reaction probabilities for the Li + H2⁺ reaction and its isotopic variants have been calculated from the threshold up to 1 eV for total angular momenta J from 0 to 90. Integral cross sections have been evaluated from the reaction probabilities at collision energies from threshold (≈0.2 eV) up to 1.0 eV collision. The calculated rate constants as a function of temperature show an Arrhenius type behavior in the 200 ≤ T ≤ 1000 K temperature interval. It has been found to be a considerable large intermolecular kinetic isotope effect. The TDWP-CC results are in overall good agreement with those obtained applying the TDWP Centrifugal-Sudden (CS) approximation, showing that the CS approximation is rather accurate for the title reaction.

Preoperative diagnostic role of hyperbilirubinaemia as a marker of appendix perforation.

This retrospective study investigated preoperative markers of appendix perforation in 351 acute appendicitis cases: group 1, appendicitis not histologically confirmed; group 2, appendicitis without perforation or gangrenous changes; and group 3, histologically confirmed perforated appendicitis with gangrenous changes. In group 3, symptom duration was significantly longer, and white blood cell (WBC) and bilirubin values significantly higher, than for the other groups. Symptom duration, gender, bilirubin and elevated WBC were significantly associated with early diagnosis of acute appendicitis in univariate analysis. Multivariate analysis identified increased WBC counts and male gender as independent variables for the early diagnosis of acute suppurative appendicitis, and symptom duration, total bilirubin and elevated WBC as independent variables for identifying appendix perforation amongst acute suppurative appendicitis patients. Receiver operating characteristic curve analysis showed good discrimination of bilirubin and moderate discrimination of WBC as markers of appendix perforation. It is concluded that assessment of preoperative total bilirubin is useful for the differential diagnosis of perforated versus acute suppurative appendicitis, whereas WBC assessment is effective for diagnosing the presence versus absence of appendicitis. Symptom duration, WBC and total bilirubin should be used as independent parameters in the early diagnosis of appendix perforation.

Expression of vascular endothelial growth factor (VEGF), hypoxia inducible factor 1 alpha (HIF-1alpha), and transforming growth factors beta1 (TGFbeta1) and beta3 (TGFbeta3) in gestational trophoblastic disease.

The aim of this study was to investigate the relationship between the expression of vascular endothelial growth factor (VEGF), transforming growth factor beta (TGF-beta1 and TGF-beta3), and hypoxia inducible factor 1 alpha (HIF-1alpha) in gestational trophoblastic diseases to highlight the possible histogenesis. Twenty-one partial hydatidiform moles (PHM), 19 complete hydatidiform moles (CHM), 13 choriocarcinomas, and 20 nonhydropic spontaneous abortions (control group) were evaluated with immunohistochemistry using VEGF, HIF-1alpha, TGFbeta1, and TGFbeta3. The extent of immunohistochemical positivity (0%=0, 1-24%=1, 25-49%=2, 50-74%=3, and greater than 75%=4) and intensity (no staining=0, weak staining=1, medium staining=2, and strong staining=3) were recorded. The expression of VEGF in spontaneous abortions and choriocarcinoma was higher than the expression in PHM and CHM. HIF-1alpha was strongly expressed in the choriocarcinomas compared to the other subgroups. Nonhydropic spontaneous abortions (control group) showed the highest TGFbeta1 expression levels among the case subgroups, followed by PHM, CHM, and choriocarcinoma (p<0.001). The expression of TGFbeta3 was seen in all groups, but the highest level of expression was observed in both CHM and choriocarcinoma. We conclude that higher levels of VEGF, HIF-1alpha, and TGFbeta3 expression in choriocarcinoma might be involved in the development of trophoblastic diseases.

Giant congenital melanocytic naevus associated with Dandy-Walker malformation, lipomatosis and hemihypertrophy of the leg.

A 30-year-old woman presented with congenital hyperpigmented plaques and multiple tumoral lesions. Her left leg was hypertrophic, although the bones were normal. Dermatological examination revealed hyperpigmented macules and plaques with hair on the legs, abdominal and lumbar areas (covering > 60% of the total body surface) and multiple naevi on the face, arms, back and chest. Multiple soft masses of various sizes, some of which colocalized with hyperpigmented plaques, were seen on the trunk and legs. Malignant melanoma was excluded by histopathological examinations of multiple biopsy specimens obtained from the pigmented lesions. Histopathological examination of one of the soft masses showed that it was a lipoma. Cranial magnetic resonance imaging and computed tomography scans showed an enlarged fourth ventricule and vermis hypoplasia (Dandy-Walker malformation; DWM). Neurocutaneous melanosis is a rare combined abnormality of the skin and central nervous system. A few case reports relating to the coexistence of giant congenital melanocytic naevus, lipomatosis and hemihypertrophy have been published in the literature. We report this very rare case of giant melanocytic naevus with lipomatosis, hemihypertrophy of the leg, and DWM.

[Successful therapy of ulcerated necrobiosis lipoidica non diabeticorum with cyclosporine A]. / Erfolgreiche Therapie einer exulzerierten Necrobiosis lipoidica non diabeticorum mit Ciclosporin.

Necrobiosis lipoidica is an inflammatory granulomatous skin disease of unknown etiology which is associated with diabetes mellitus in about 60% of the patients. In 15-35% of the affected patients painful ulcerations may occur after minimal trauma which can be extremely refractory to therapy. Because of the unknown pathomechanisms, current therapeutic options are limited. We report on a 68-year-old patient with an 18 year history of ulcerated necrobiosis lipoidica non diabeticorum of both lower limbs, which responded to systemic cyclosporine A. Based on this case, we discuss the role of cyclosporine A in patients with necrobiosis lipoidica in the context of the disease etiology.

Malignant struma ovarii: a case report.

Malignant struma ovarii is a rare form of the ovarian germ cell tumors. Hence, diagnosis and management of malignant struma ovarii have not been clearly defined. We present the case of a 34-year-old woman with papillary carcinoma arising in struma ovarii. The malignant component of this tumor was detected after laparoscopic removal, and a re-staging operation was performed afterwards. There was no evidence of clinical malignancy or metastases. In this paper, clinical features, treatment guidelines, diagnostic features, and immunohistochemical characteristics of this tumor are reviewed.
