Abstract
To assess the impact of vehicular emissions on a mixed conifer forest, we measured the contents of the trace elements, N, C, and their respective natural isotopes (δ(15)N and δ(13)C), in the epiphytic lichen, L. vulpina. The samples were collected along transects perpendicular to Interstate 80 (I-80) and along a more remote, secondary forest road (R07). Distance to the road verge, trunk cover, and stand basal area were also recorded. Percent N ranged from 1.10% to 2.00% near I-80 and from 0.78% to 1.13% along R07. Concentrations of N, (15)N, Na, As, Pb, and Zn were enhanced in lichen samples near I-80 and were negatively correlated with distance from the road. Trunk cover values differed between roads (p<0.001) and were negatively correlated with %N (r(2)=0.74; p<0.001). The results indicate that vehicular N emissions are significant enough to alter the surrounding ecosystem, modifying the presence of a sensitive component such as L. vulpina, and suggest that a clean-site threshold of 1.0%N may be too high as an indicator of critical N load exceedance. The study also underscored the potential role of wolf lichen in a large-scale assessment of N deposition and source identification.

Abstract
OBJECTIVE To investigate the relationship between speech auditory brainstem responses (speech ABRs) and word intelligibility under reverberation in elderly adults. METHODS Word intelligibility for words under four reverberation times (RTs) of 0, 0.5, 1.0, 1.5s, and speech ABRs to the speech syllable/da/ were obtained from 30 elderly listeners. Root mean square (RMS) amplitudes and discrete Fourier transform (DFT) amplitudes were calculated for ADD and SUB responses in the speech ABRs. RESULTS No significant correlations were found between the word intelligibility scores under reverberation and the ADD response components. However, in the SUB responses we found that the DFT amplitudes associated with H4-SUB, H5-SUB, H8-SUB, H9-SUB and H10-SUB significantly correlated with the word intelligibility scores for words under reverberation. With Bonferroni correction, the DFT amplitudes for H5-SUB and the intelligibility scores for words with the RT of 0.5s and 1.5s were significant. CONCLUSIONS Word intelligibility under reverberation in elderly listeners is related to their ability to encode the temporal fine structure of speech. SIGNIFICANCE The results expand knowledge about subcortical responses of elderly listeners in daily-life listening situations. The SUB responses of speech ABR could be useful as an objective indicator to predict word intelligibility under reverberation.

Abstract
The purpose of this retrospective study was to assess the efficacy of salvage radiation therapy (RT) or chemoradiation therapy (CRT) for locoregional recurrence (LR) of esophageal cancer after curative surgery. Forty-two patients who received salvage RT or CRT for LR of esophageal cancer after curative surgery between November 2000 and May 2012 were reviewed. The intended RT regimen was 60 Gy in 30 fractions combined with concurrent platinum-based chemotherapy. Median follow-up periods were 17.9 months for all evaluable patients and 28.2 months for patients still alive (19 patients) at analysis time. The 1-, 2-, and 3-year survival rates were 81.2 ± 6.4%, 51.3 ± 8.6%, and 41.1 ± 8.7%, respectively, with a median survival time of 24.3 ± 4.1 months. Out of 41 evaluable patients, 16 patients (39%) were alive beyond 2 years from salvage therapy. However, univariate analyses for overall survival showed no significant prognostic factor. Grade 3 or higher leukocytopenia was observed in 46% of the patients. Salvage RT or CRT for LR after surgery for esophageal cancer was safe and effective. These therapies may offer long-term survival to some patients. RT or CRT should be considered for LR.

Abstract
BACKGROUND Recently, driver tyrosine kinase gene mutations have been detected in malignant tumors, including lung tumors. Notwithstanding their attractiveness as targets for molecular therapy, limited information is available regarding BRAF-mutated lung carcinomas. MATERIALS AND METHODS BRAF mutation status was determined in 2001 surgically resected nonsmall-cell lung cancer (NSCLC) cases using high-resolution melting analysis (HRMA) followed by Sanger sequencing and/or deep sequencing using next generation sequencer. RESULTS BRAF mutations were detected in 26 (1.3%) of 2001 NSCLC cases (25 adenocarcinomas and 1 squamous cell carcinoma). In the 26 cases, 13 mutation genotypes were identified, including V600E (8 of 26; 30.8%), G469A (6 of 26; 23.1%), K601E (4 of 26; 15.4%), and other residual mutations (1 of 26; 0.04%). Of the 13 genotypes, 4 genotypes (G464E, G596R, A598T, and G606R) had not been previously reported in lung cancer. The overall survival rate was not significantly different between patients with wild-type BRAF and those with V600E or non-V600E BRAF mutations (P = 0.49 and P = 0.15, respectively). Histomorphological analysis revealed that focal clear cell changes were present in 75% of V600E-mutated tumors. All V600E BRAF-mutated tumors were negative for other driver gene alterations including epidermal growth factor receptor (EGFR) and KRAS mutations and the anaplastic lymphoma kinase gene translocation, whereas five tumors with non-V600E BRAF mutations (four G469A and one G464E/G466R) showed concomitant EGFR mutations. CONCLUSION The frequency of BRAF mutations in lung cancer was low in an Asian cohort. Furthermore, BRAF mutation status lacked prognostic significance in this patient population.

Abstract
A total of 100 patients with benign prostatic hyperplasia (BPH) and overactive bladder (OAB) symptoms (BPH/OAB), enrolled between June 2006 to March 2008, were randomly divided into 2 groups of morning medication (M) and evening medication (E) groups, then 50 mg of naftopidil was given once a day after breakfast or supper for 8 weeks. Data were available for efficacy analysis on 80 patients (M group ; 43, E group ; 37). Naftopidil significantly improved the overall international prostatic symptom score ; from 19.2±7.9 to 11.7±5.8 in the M group and from 19.4±6.4 to 12.3±6.8 in the E group (p<0.0001), QOL score from 4.9±0.8 to 3.2±1.4 in the M group and from 5.0±0.8 to 3.6±1.3 in the E group (p<0.0001), and OAB symptom score from 7.8±2.6 to 5.0±2.5 in the M group (p<0.0001) and from 8.6±2.9 to 5.8± 3.3 in the E group (p<0.0001). There was no significant difference in the incidence of adverse effects between the M group (6.1%) and E group (2.2%). These results suggest that naftopidil improves storage symptoms as well as voiding symptoms regardless of timing of administration.

Abstract
To investigate the efficacy and toxicity of definitive chemoradiotherapy (CRT) for elderly patients with locally advanced esophageal cancer. Twenty-two patients aged over 75 that performed definitive CRT were retrospectively reviewed. The regimen included concurrent CRT consisting of two cycles of chemotherapy (CTx) of platinum and 5-fluorouracil, and radiation therapy (RT) of 50-50.4 Gy (actual range: 45.4-71.4 Gy), and additional CTx where possible. Both CTx and RT were reduced in dose and field where necessary. The disease-free survival rate and the overall survival rate at 3 years were 33.3% ± 11.4% and 25.9% ± 10.8%. Grade 4 leukocytopenia and thrombocytopenia occurred in three (14%) and four (18%) patients. Treatment-related death was suspected in up to four (18%) patients at the most. Univariate analyses for disease-free survival showed that neither total radiation dose nor number of total cycles of CTx was significant. The pattern of relapse was predominantly more frequent in the intra-RT field than outside the RT field. For elderly patients, adverse events are frequent, and decreased organ reserve may cause treatment-related death. Reduction in CTx dose or RT field, appropriate only for two cycles of CTx, and careful monitoring may help to minimize toxicity. Physicians should not be too afraid of adverse events or be negative about CRT for elderly patients, as long as comorbidities and complications are managed carefully.
