Background: The present study aimed to determine the prevalence and types of sexual problems of Turkish patients receiving gynecologic cancer treatment. Materials and Methods: A cross-sectional convenience sample of 168 women completed the Index of Female Sexual Function (IFSF) and a Patient Identification Form in a hospital in Ankara, Turkey. Mean IFSF scores of the patients were low ($15.7{\pm}5.72$, out of a possible 45), indicating high rates of sexual problems. Results: Women frequently reported problems with dyspareunia (97.1%), vaginal dryness (97.6%), decreased sexual desire (91.1%), and difficulties of sexual arousal (92.9%) related with the cancer treatment process. They reported increased sexual problems following the period of treatment as compared to before treatment (p<0.05). Sexual dysfunction was associated with low educational and income levels, advanced age, TAH-BSO-LND surgery (total abdominal hysterectomy-bilateral salphingoopherectomylymph node dissection), experiencing side effects of chemotherapy, receiving chemotherapy in addition to surgery and radiotherapy (CT+RT+Surgery), and having a large number of chemotherapy cycles (p<0.05). Conclusions: Patients hoped for and expected counseling from healthcare professionals about their sexual functioning in relation to cancer treatments. Nurses and physicians can help to improve the overall quality of life for gynecologic cancer patients through sexual counseling.

Objectives: The number of patients undergoing oral anticoagulant therapy for cardiovascular and cerebrovascular disease is increasing. However, the risk of bleeding after tooth extraction in patients receiving warfarin is unclear. Here, we assess the risk of bleeding after tooth extraction in patients on warfarin. Materials and Methods: The study included 260 patients taking warfarin who underwent tooth extraction (694 teeth). The patients were divided into those whose teeth were extracted while they were taking warfarin, those who discontinued warfarin before extraction, and those who underwent extraction while receiving heparin bridging therapy. Bleeding complications in the two groups were compared. Results: Of the 260 patients, 156 underwent extraction while taking warfarin, 70 stopped taking warfarin before extractions, and 34 received heparin bridging therapy and stopped taking either medication before extractions. Bleeding complications occurred in 9 patients (3.5%) and 9 tooth sites (1.3%). Among the 9 patients with bleeding complications, 6 underwent extraction while taking warfarin, 2 stopped warfarin before extraction, and 1 underwent extraction after receiving heparin bridging therapy. No significant difference was seen between patient groups regarding bleeding after extractions (P=0.917). Conclusion: Warfarin use does not increase the risk of post-extraction bleeding and can therefore be continued during tooth extraction.

In this study, the piezoelectric ceramics/polymer composite transducers with 1-3 connectivity have been studied. A piezoelectric ceramics PZT prepared by Wet-Dry Combination method was used as a filler in polymer matrix Eccogel. We've got the pulse-echo response for 1-3 type piezc-electric composite transducers in water. It was shown that the transmitting and receiving sensitivity of 1-3 type piezoelectric composite transducers could be improved in comparison with that- of solid PZT transducers. The reason is for that 1-3 type Piezoelectric composites have low dielectric constant and density. There was in a good agreement between the resonant frequencies calculated from one period and observed results on the Ultrasonic Transducer Analyzer. According to these results we could be figured out the distance in water by virture of the pulse-echo response.

This study analyzes the form of sleeve heads, which is an important internal element that affects the appearance of jacket sleeves. It characterized sleeve head forms by investigating angles, materials, and a combination of formations for 50 sleeve heads. It conducted an appearance evaluation by comparing and analyzing the results. This paper develops a sleeve head appropriately for sleeve construction. The study results are as follows. First, the product was divided into three parts: based on, force receiving, and sleeve cap parts. There were four types of man's sleeve head: straight, arc, and curve A and B types. The woman's sleeve head had two types: straight and curve B type. Second, the feature of each type of sleeve head was analyzed. A straight type emphasized the based on part. An arc type highlighted the force receiving part while the based on part decreased. The sleeve cap part, force receiving part, and based on part were emphasized in the arc type sleeve head. Third, as a result of the appearance evaluation, each type was rank as straight type < arc type ${\leq}$ curve A < curve B. The straight type did not get positive results as it had extra ease when the sleeve head was attached to a Jacket Sleeve. The arc type was evaluated poorly due to an inappropriate sleeve cap composition. The curve type received an excellent overall outcome as it fit into the sleeve cap part well and highlighted the force receiving part in order to minimize front and back wrinkles. Therefore, the curve type made the resemblance of the jacket appearance perfect and closest to the sleeve pattern.

Background: Adjuvant chemotherapy improves survival in Dukes C colon cancers post-curative resection. However, the evidence for a role with Dukes B lesions remains unproven despite frequent use for disease characterized by poor prognostic features. In view of limited Asia-specific data, this study aimed to determine survival outcomes and identify prognostic factors in a tertiary teaching hospital in Malaysia. Materials and Methods: A total of 116 subjects who underwent curative surgery with and without adjuvant chemotherapy for Duke B and C primary colon adenocarcinomas diagnosed from 2004-2009 were recruited and data were collected retrospectively. Five-year overall survival (OS) and disease free survival (DFS) were analysed using Kaplan-Meier survival analysis and log-rank (Mantel-Cox) test. Prognostic factors were determined using Cox proportional hazards regression with both univariate and multivariate analyses. Results: The survival analysis demonstrated a 5-year OS of 74.0% for all patients, with 74.9% for Dukes C subjects receiving chemotherapy compared to 28.6% in those not receiving chemotherapy (p=0.001). For Dukes B disease, the 5-year survival rate was 82.6% compared to 75.0% for subjects receiving and not receiving chemotherapy, respectively (p=0.17). Independent prognostic factors identified included a CEA level more than 3.5 ng/ml (hazard ratio (HR)=4.78; p=0.008), serosal involvement (HR=3.75; p=0.028) and completion of chemotherapy (HR= 0.20; p=0.007). Conclusions: In a regional context, this study supports current evidence from the West that adjuvant chemotherapy improves survival in Dukes C colon cancers post curative surgery. However, although a clear benefit has yet to be proven for Dukes B disease, our results suggest survival improvement in selected cases.

Background: Antiemetic triplet therapy including dexamethasone (DEX) is widely used for patients receiving highly emetogenic chemotherapy (HEC). In Japan, the appropriate dose of DEX has not been established for this combination. Materials and Methods: To assess the efficacy and safety of increased-dose DEX, we retrospectively examined patients receiving HEC with antiemetic triplet therapy. Results: Twenty-four patients (fosaprepitant group) were given an increased-dose of DEX (average total dose: 45.8mg), fosaprepitant, and 5-HT3 antagonist. A lower-dose of DEX (33.6mg), oral aprepitant, and 5-HT3 antagonist were administered to the other 48 patients (aprepitant group). The vomiting control rates in the fosaprepitant and aprepitant groups were 100% and 85.4% in the acute phase, and were 75.0% and 64.6% in the delayed phase. The incidences of toxicity were similar comparing the two groups. Conclusions: Triplet therapy using an increased-dose of DEX is suggested to be safe and effective for patients receiving HEC.

Purpose: To evaluate intracranial control after surgical resection according to the adjuvant treatment received in order to assess the optimal radiotherapy (RT) dose and volume. Materials and Methods: Between 2003 and 2015, a total of 53 patients with brain oligometastases from non-small cell lung cancer (NSCLC) underwent metastasectomy. The patients were divided into three groups according to the adjuvant treatment received: whole brain radiotherapy (WBRT) ${\pm}$ boost (WBRT ${\pm}$ boost group, n = 26), local RT/Gamma Knife surgery (local RT group, n = 14), and the observation group (n = 13). The most commonly used dose schedule was WBRT (25 Gy in 10 fractions, equivalent dose in 2 Gy fractions [EQD2] 26.04 Gy) with tumor bed boost (15 Gy in 5 fractions, EQD2 16.25 Gy). Results: The WBRT ${\pm}$ boost group showed the lowest 1-year intracranial recurrence rate of 30.4%, followed by the local RT and observation groups, at 66.7%, and 76.9%, respectively (p = 0.006). In the WBRT ${\pm}$ boost group, there was no significant increase in the 1-year new site recurrence rate of patients receiving a lower dose of WBRT (EQD2) <27 Gy compared to that in patients receiving a higher WBRT dose (p = 0.553). The 1-year initial tumor site recurrence rate was lower in patients receiving tumor bed dose (EQD2) of ${\geq}42.3Gy$ compared to those receiving <42.3 Gy, although the difference was not significant (p = 0.347). Conclusions: Adding WBRT after resection of brain oligometastases from NSCLC seems to enhance intracranial control. Furthermore, combining lower-dose WBRT with a tumor bed boost may be an attractive option.

Dye-sensitized solar cells (DSSCs) have been receiving growing attentions as a potential alternative to order photovoltaic devices due to their high efficiency and low manufacturing cost. DSSCs are composed of a photosensitizing dye adsorbed on a mesoporous film of nanocrystalline $TiO_2$ as a photoelectrode, an electrolyte containing triiodide/iodide redox couple, and a platinized counter electrode. To improve photovoltaic properties of DSSCs, new dicationic salts based on ionic liquids were synthesized. Quite comparable efficiencies were obtained from electrolytes with new dicationic iodide salts. The best cell performance of 7.96% was obtained with dicationic salt of PBDMIDI.
