  • The malignant small round cell tumor of the thoracopulmonary region was described by Askin in 1979 and called as Askin Tumor. The Askin tumor is a rare, arises from the soft tissues of the chest wall or peripheral lung which is predominantly in younger generation. Clinical and pathologic appearance were very similar to Ewing's sarcoma and rhabdomyosarcoma but when examined it by electron microscopy, there was some different in morphology. The tumor tended to recur locally and did not seem to disseminated widely but the median survival was only 8 months.

  • Askin tumor is rare malignant small round cell tumor that orgins from interconstal nerve of chest in children It was not until 1979 that Askin first reported that tumor. Although few sporadic reports had been reported, its incidence were too low to analize its clinical featurs. That tumors prognosis is so grave that no therapy would success to cure, but early diagnosis and enbloc excision with following combind chemotherapy and radiotherapy will prolong their survival. Other small round cell tumors of chest wall that must differentiate are Ewing`s sarcoma, rhabdomyosarcoma, lymphoma, neuroblastoma and pulmonary bla-stoma. The most prominant histologic charactersistics of this tumor is neuron specific eno-lase which is detected with immunohistochemistry technique, and neurosecretary electron dense granules within cytoplasm. We expirienced a case of Askin tumor occuring 12-year-old female who has huge right lower chest mass with dull chest pain. She have been underwent excision and postoperative radiotherapy. We are following her up for months and there is no evidence of local recurrence.

  • Recently, polyester is widely used in textile fabrics due to its application potentials in various fields. It is known that askin fabric is prepared with mainly polyester and is enjoyed with various end uses such as marine clothing, underwear, shirts, swimming suits and so on. For this purpose, color fastness should be considered with great importance during its wet processing step. In this context, vat dyes were very much attracted due to the advantage of superior fastness property. Thus, we have used indigo dye towards askin fabric dyeings and investigated corresponding properties namely, dyeing temperature, concentration of dye, reducing agent amount and alkali amount. The results showed that higher color strengths of indigo dyeing on askin fabric were obtained at $110^{\circ}C$, 8% o.w.f, 3g/l, 5g/l, respectively. The color fastness to washing was considerable generally.

  • Malignant small round cell tumor (SRCT) of the thoracopulmonary region appears to originate in the soft tissues of the chest wall or the peripheral lung. A differential diagnosis of poorly differentiated small round cell tumors which include Ewing's sarcoma of bone and soft tissue, embryonal rhabdomyosarcoma, Askin tumor, neuroblastoma, peripheral neuroectodermal tumor, small cell osteogenic sarcoma and Iymphoma are often difficult by light microscopy alone. In recent, by the extensive studies electron microscopic examination, histochemical study, immune-chemical study, cytogenetics and gene analysis, these tumors may be derived from the primitive and pluripotential cells, differentiating into mesenchymal, epithelial and neural features in variable proportions. Treatment for SRCT of thoracopulmonary region is not determined because of massive involvement of the lung, pleura or soft tissues of the chest wall resulted in a dismal outcome despite aggressive surgery, irradiation and chemotherapy.

  • The current study was carried out to determine the influence of different resting surfaces and stall types on milk yield and animal health. Study was carried out in Bursa that is one of the most important cities of Turkey in terms of dairy production. Effects of resting surfaces and stall types on milk yield were found to be important. Also influence of different resting surfaces and stall types on lactation length was examined and found that rubber mats were different from the two other options. Relationships between different resting surfaces or stall types and health problems were examined and connection between stall type and repeat breeding (RB), dystocia, retained placenta and a connection between resting surface types and RB and clinical mastitis were found to be important. Considering their economic reflections, it can be said that results are quite important to the Turkish dairy industry.

  • Cyclospora cayetanensis is an agent of emerging infectious disease, and a recognized cause of diarrhea in some patients. Also, the flagellated protozoan, Giardia intestinalis, induces a diarrheal illness of the small intestine. Cases of cyclosporiasis are frequently missed, primarily due to the fact that the parasite can be quite difficult to detect in human fecal samples, despite an increasing amount of data regarding this parasite. On the other hand, G. intestinalis can be readily recognized via the microscopic visualization of its trophozoite or cyst forms in stained preparations or unstained wet mounts. In this report, we describe an uncommon case of co-infection with G. intestinalis and C. cayetanensis in an immunocompetent patient with prolonged diarrhea, living in a non-tropical region of Turkey.

  • Objectives: The purpose of this study is to investigate the effects of aerobic exercise and acupuncture treatment in obese patients. Methods: The effects of exercise in obese patients receiving acupuncture therapy were investigated in this retrospective, case-controlled study in which subjects complying with exercise were enrolled in the case and non-compliers were enrolled in the control group. Results: There was a statically significant weight loss in both the study case group (94.39 ± 20.36; 88.91 ± 19.00; n = 22; p = 0.001) and the control group (103.18 ± 21.92; 99.56 ± 21.92; n = 34; p = 0.001) after 3 months. Weight loss occurred in all 22 patients in the case group. In the control group, while weight loss occurred in 27 of the 34 patients, weight gain occurred in three patients. Conclusion: In conclusion, the addition of modalities such as acupuncture, exercise and diet may provide effective improvement in weight control.

  • In this study, shear strength behavior of fine-grained soils was investigated under unsaturated conditions. The samples in the unsaturated state were subjected to a net normal stress (σ-ua) of 40 kPa and different matric suctions (ua-uw) of 50, 100 and 150 kPa. The matric suction values applied in the triaxial tests were selected according to the bubbling pressures determined from the SWC curves. The study was carried out on prepared re-constituted cylindrical samples by uniaxial consolidation of soil slurries. First, consolidated drained (CD) triaxial compression tests were performed on the saturated samples and the cohesion and angle of internal friction were determined. After that, drained triaxial compression tests under matric suctions were performed on the unsaturated samples. In order to obtain unsaturated test results, cohesion and internal friction angle values of saturated samples were used. The nonlinear surface representing the shear strength surface was approximated consisting of two planes (double planar surface). The reason for the nonlinear behavior of some soils is that the amount of sand content contained in it is relatively high and the bubbling pressure/permanent water content value is relatively low.

  • Aim: To evaluate the relationship between pre-operative CA-125 levels and myometrial invasion in patients with early-stage endometrioid-type endometrial cancer. Materials and Methods: Two-hundred and sixty patients were diagnosed with endometrial cancer between January 2007 and December 2012. Of these, 136 patients with stage 1 endometrioid histologic-type and documented pre-operative serum CA-125 levels were included in the study. Age, preoperative CA-125 level, histologic grade, surgical grade, and presence of deep myometrial invasion were recorded. Additionally, 16, 20, and 35 IU/ml cutoff values were used and compared to evaluate the relationship between pre-operative CA-125 levels and myometrial invasion. Results: The average serum CA-125 level was $35.4{\pm}36.7$ in patients with deep myometrial invasion, and $21.5{\pm}35.8$ in cases without deep myometrial invasion. The relationship between the presence of deep myometrial invasion and CA-125 cut-off values (16, 20, 35 IU/ml) was statistically significant, although the correlation was weak (p<0.05). When the relationship between 16, 20 and 35 IU/ml CA-125 cut-off values and the presence of deep myometrial invasion was studied, specifity and sensitivity values were identified as: 0.60-0.68 for 16 IU/ml; 0.73-0.48 for 20 IU/ml; and 0.89-0.33 for 35 IU/ml. The sensitivity of 16 IU/ml cut-off value was higher when compared to other values. Conclusions: This study demonstrates that preoperative serum CA-125 values maybe used as a predictive test in patients with early stage endometrioid-type endometrium cancer, and as a prognostic factor alone. Further studies should be conducted to identify different CA-125 cut-off values in patients with low risk endometrial cancer.
