The abscopal effect refers to an anti-tumor response that occurs in areas where radiotherapy (RT) has not been directly administered but is triggered by the immune system. We presented a case of an undifferentiated pleomorphic sarcoma with three relapses that showed a complete response after distant metastatic disease. The tumor was initially detected in the left pectoral muscle. Fifteen months after adjuvant RT and chemotherapy, a nearby recurrent lesion was surgically removed. Another 15 months later, a second recurrence appeared on the left lateral chest wall. The patient underwent a third surgery and received adjuvant radiation, but distant metastases were discovered 6 months later. Shortly after a biopsy confirmed distant metastasis, all metastatic foci went into spontaneous remission. This phenomenon is identified as the abscopal effect. The patient experienced no metastasis or local recurrences during follow-up and showed a complete response to the abscopal effect for 36 months. The abscopal effect in malignant mesenchymal tumors is extremely rare.

Introduction: Facial nerve schwannoma is a rare benign tumor which may originate from any segment of the facial nerve. We present a case of a giant cystic facial nerve schwannoma that showed extension to the middle cerebral fossa, together with its clinical and radiological characteristics, and a short review of the related literature. Case Report: A 52-year old female patient attended with complaints of numbness in the right half of her face, and mild hearing loss. Examinations revealed House-Brackmann Grade 3 peripheral facial paralysis, sensorineural hearing loss of 30% in her right ear. She described three episodes of facial paralysis in the last six years. Cranial MRI and CT scan revealed a round cystic lesion of about 40x44x38 mm, located centrally and medially in the right temporal area. The surgical operation was performed and the lesion was totally extracted. The histopathological investigation reported the lesion as a schwannoma. Conclusion: Facial nerve schwannoma is a rare, benign tumor that occurs in different localizations. It may commonly be mistaken in prediagnosis and may be confused with other clinical states due to its clinical characteristics. It has to be kept in mind in the prediagnosis of patients with facial paresis and hearing loss.

Plant sterols are important agricultural products for human health and consequently, for nutrition industries. In the present study, free sterol contents of crude Turkish cottonseed oil samples have been determined in a single analytical run by using a solid phase extraction step prior to the detection with a gas chromatography coupled with a flame ionization detector. Free hydroxyl groups of Stigmasterol, β-Sitosterol, Campesterol and Brassicasterol were derivatized by using N-methyl-N-trimethylsilyl trifluoroacetamide to enhance their volatility and, sterol content of the samples were, then, separated from their matrix by using a octadecylsilane cartridge. The eluates were injected into the gas chromatographic system and satisfactory recovery ratios were obtained. After having validated the method, it was applied into the analysis for cottonseed oil samples for their free sterol levels.

Purpose: Information regarding the effects of primary ciliary dyskinesia (PCD), a rare usually autosomal recessive disease, on exercise capacity is limited. In this study, we aimed to compare aerobic capacity of children with PCD those with age-and sex matched healthy counterparts. Material and Methods: Fifteen patients with PCD (13.1±3.1 years) were participated, and 15 age- and sex- matched healthy children (13.3±3.2 years) were enrolled as controls. Patients underwent pulmonary function testing, a modified shuttle walk test was performed. Heart rate, blood pressure, oxygen saturation (Sa02), and fatigue were recorded before and after the exercise test. Results: Physical characteristics of the two groups were similar (p>0.05). The PCD subjects’ forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory flow between 25% and 75% (FEF25-75%), forced expiratory flow at 25% (FEF25%), forced expiratory flow at 50% (FEF50%), forced expiratory flow at 75% (FEF75%), peak expiratory flow (PEF), shuttle walk test distance, and peak exercise heart rate, Sa02 values during exercise were significantly lower than those of healthy subjects (p
