The carrier dynamics in organic photovoltaic (OPV) cells were investigated by impedance spectroscopy. We introduced a novel impedance spectrum representation called dynamic modulus plot (DMP), which allowed us to observe the layer-to-layer carrier injection behavior graphically. In this work, the impedance responses were characterized in the N,N’-diphenyl-N,N’-di-m-tolyl- 4,4’-diaminobiphenyl (TPD)/C60 p-n heterostructured OPV cells against applied voltages. The dependence of impedance responses on the layer thickness revealed a constant internal electric field that disturbed the carrier transport within the OPV cells. We applied this technique to new donor materials, in which thiophene units were inserted to the center of TPD. By increasing the number of thiophene units in TPD the fill-factor (FF) improved from 33% to 59%, which increased the power conversion efficiency (PCE). Based on the DMP analysis, we assigned the improvement in device performance to the reduction of the internal electric field.

Malignant spinal cord compression (MSCC) rarely presents in patients with endometrial cancer. It usually occurs months or years after the diagnosis of the primary tumor. A 65-year-old woman presented with a huge uterine tumor suspecting leiomyosarcoma. She underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. Histopathological examination revealed mixed carcinoma (small cell carcinoma and endometrioid adenocarcinoma) of the endometrium. She presented with upper abdominal pain, back pain, cystoplegia and paraplegia of lower extremities postoperatively. Magnetic resonance imaging revealed bone metastasis with destruction of the eighth thoracic vertebral body as the sites of metastasis. Vertebrectomy and irradiation therapy were performed for the lesion. Although she received systemic chemotherapy consisting of paclitaxel and carboplatin, she died 4 months after hysterectomy.

AIM To examine usefulness of virtual biopsy using endocytoscopy by comparing the in vivo endocytoscopic and histopathological images of gastric *** Endocytoscopy was performed in 30 patients with early gastric cancer. Of these, 26 patients showed well differentiated adenocarcinomas, while 4 patients showed poorly differentiated adenocarcinomas(including one signet ring cell carcinoma). Cancerous and non-cancerous areas were observed after double staining with 0.05% crystal violet and 0.1% methylene blue. The endocytoscopic images obtained were evaluated by an expert endoscopist and an expert pathologist without knowledge of patient clinical data, and endocytoscopic and histopathological diagnoses were *** The endocytoscopic images of the cancerous area were assessed as evaluable in 25(83.3%) and 27(90%) patients by endoscopist A and pathologist B, respectively, and those of the non-cancerous area as evaluable in 28(93.3%) and 23(76.7%) patients by the endoscopist and pathologist, respectively. The sensitivity, specificity, and diagnostic accuracy of gastric cancer diagnosis using evaluable endocytoscopic images were 88.0% and 92.9%, and 90.6% by endoscopist A, and 88.9% and 91.3%, and 90.0% by pathologist B, respectively. Evaluation of the diagnostic concordance rate between the endoscopist and the pathologist by inter-observer agreement calculation revealed no significant difference between the two observers. The inter-observer agreement(κ-value) for endocytoscopic diagnosis was 0.745. CONCLUSION Endocytoscopy is useful for the differentiation of cancerous from non-cancerous gastric mucosa, making it a promising tool for virtual biopsy.

A compound disinfectant, which consisted of didecyldimethylammonium chloride (DDAC), ortho-dichlorobenzene (1,2-dichlorobenzene, ODB), and chlorocresol (4-chloro-3-methylphenol, CC), and its component chemicals were individually tested for effectiveness against bovine herpes virus type 1 (BHV-1). DDAC, DDAC+ODB, DDAC+CC, and DDAC+ODB+CC showed effectiveness against BHV-1 at room temperature. However, ODB, CC, and ODB+CC showed no virucidal effects. The effects of all disinfectants tested were decreased at low temperature. DDAC showed disinfectant effects at a dilution of 1/800 and DDAC+ODB, DDAC+CC, and DDAC+ODB+CC at dilutions of 1/800 and 1/1600 at low temperature in the presence of 2% fetal bovine serum (FBS) but ODB, CC, and ODB+CC showed no virucidal effects. At low temperature and in the presence of 10% FBS, DDAC, DDAC+ODB, and DDAC+CC showed disinfectant effects at dilutions of 1/800, whereas ODB, CC, and ODB+CC showed no virucidal effects. DDAC+ ODB+CC was more effective (at 1/800 and 1/1600) than the other disinfectants under these conditions. In conclusion, a combination of three disinfectant components (DDAC+ODB+CC), enhanced the disinfectant effects at low temperature and in organic matter contamination.

The objective of the present study was to assess the relationship of response time and peak latency of P300 with a simple-reaction task. Seven male subjects who were experienced players in decision-making sports were included. Two main findings were noted. First, the P300 latencies of Fz and Pz were correlated with visuo-motor related time. Second, in terms of latencies of visual evoked potentials, the correlations were observed only between Oz-P2 latency and visuo-motor related time. These results suggest that the length of visuo-motor related time is related to the processing involved in the higher order brain site involving specific processing in the visual cortex.

Purpose: This study was designed to determine the influence of preoperative irradiation and surgical operation on salivary secretion impairment in patients with oral squamous cell carcinoma (OSCC)。Methods: A total of 42 patients with OSCC were studied between 2004 and 2008。Salivary secretion was evaluated by Saxson's test before and 3-4 weeks after preoperative 30 Gy of irradiation, and at various intervals after surgery。Results: After preoperative irradiation, salivary secretion was 40.8% compared with pretreatment salivary secretion, then 27.8% 6 months after surgery。In several patients whose data we can get by Saxson's test more than 6 months after surgery, salivary secretion markedly increased between 12 and 24 months after surgery。Conclusions: In-patient with OSCC received preoperative irradiation and surgery, salivary secretion was about 30% 6 months after operation, then likely to recover significantly between 12 and 24 months after surgery。

Objective: Urine 8-hydroxy-deoxyguanosine (U8-OHdG) was a marker of oxidative stress-induced DNA damage;it was increased by psychological stress. Since the menstrual cycle may confound or modify the association between psychological stress and U8-OHdG. The aim of this study was to verify the effect of psychological stress from a national license examination on levels of U8-OHdG, which is a biomarker of oxidative stress. And the effects of women’s menstrual cycles, which should be considered in mental and physical assessments, on U8-OHdG, were evaluated. Methods: The subjects were 18 female university students at a medical university in whom Self-rating Depression Scale (SDS) scores, State-Trait Anxiety Inventory (STAI) scores, and U8-OHdG levels were measured in 3 phases of the menstrual cycle, the follicular phase, ovulatory phase, and luteal phase. The mean values were taken for the group during a time of classroom learning. The same measurements were also made one week before and the day after a national license examination and the measurements were compared among the three periods. Results and Conclusion: State anxiety and U8-OHdG levels were significantly higher in those with a week before the national license examination than in those with classroom lecture (State anxiety: p = 0.002, U8-OHdG levels: p = 0.007). The menstrual cycle did not show a significant correlation with U8-OHdG levels. This study demonstrated that levels of the oxidative stress biomarker U8-OHdG are not affected by changes in the menstrual cycle. It also showed that U8-OHdG levels increased with the psychological stress of a national license examination.
