Abstract
Although a decrease in cerebrovascular reserves (CVR) is known to enhance the risk of stroke, changes in this parameter after carotid artery stenting (CAS) have rarely been investigated. The present study is the first to compare CVR recoveries after applying CAS to patients with symptomatic carotid artery disease. CAS was performed for 31 consecutive patients with symptomatic carotid artery disease. They underwent acetazolamide-challenged single photon emission computed tomography (SPECT) before and after CAS to obtain data on resting stage cerebral blood flow (CBF(rest) values) in various regions of interest (ROIs) defined by a three-dimensional stereotactic ROI template. CVR values on ipsilateral and contralateral hemispheric sides were then calculated based on the CBF(rest) data. The 31 patients were dichotomized into unilateral (n=22) and bilateral (n=9) lesion groups, and no significant between-group differences were observed in CBF(rest) before and after CAS. In the unilateral group, there were no differences in CVR values before and after CAS. In the bilateral group, however, the CVR values significantly increased in nearly all the investigated ROIs on the contralateral side. Also, the hemispheric CVR values on both sides significantly increased after CAS in the bilateral group, while no such increase was observed in the unilateral group. CAS in patients with symptomatic bilateral carotid artery disease has the potential utility for their haemodynamic improvement even on the contralateral hemispheric side.

Abstract
We report on the direct conversion of laser-cooled 41K and 87Rb atoms into ultracold 41K87Rb molecules in the rovibrational ground state via photoassociation followed by stimulated Raman adiabatic passage. High-resolution spectroscopy based on the coherent transfer revealed the hyperfine structure of weakly bound molecules in an unexplored region. Our results show that a rovibrationally pure sample of ultracold ground-state molecules is achieved via the all-optical association of laser-cooled atoms, opening possibilities to coherently manipulate a wide variety of molecules.

Abstract
Clinical successful application of dentine adhesives depends not only on material-related but also on operator-related factors. The purpose of this study was to evaluate the dentine bonding effectiveness of a self-etch composite cement applied by operators with or without clinical experience under well-standardized, randomized and blind conditions. Forty-eight bovine dentine surfaces were randomly divided into two groups. The first group consisted of eight dental students with no clinical experience at all, and the second group consisted of eight dentists with extensive experience in adhesive dentistry (mean experience of 11.4 years). Next, a 4-mm-diameter stainless steel rod (SUS-304) was bonded to the dentine surface using Panavia Fluoro cement (Kuraray Medical Inc., Tokyo, Japan). After application procedures, the specimens were randomized and shear bond-strength measurements were performed by a single blinded operator. Mann-Whitney U test was used to determine statistical differences in bond strength between the two groups, and Kruskal-Wallis was used to determine statistical difference between the student and dentist groups. The means and standard deviations of bond strength were 11.5 +/- 8.1 MPa for the student group and 7.1 +/- 4.3 MPa for the dentist group, respectively. The bond strength of the student group was significantly higher than that of the dentist group. However, the variability in bond strength was significantly higher in the student group, and some specimens failed prior to actual testing (included as 0 MPa). Clinical experience did not have a positive effect on the bonding effectiveness of the self-etch composite cement to dentine.

Abstract
We report a case of testicular thecoma in an 11-year-old Japanese boy with nevoid basal-cell carcinoma syndrome (Gorlin syndrome). He presented with left testicular swelling and underwent a radical orchiectomy on suspicion of a malignant paratesticular tumor. The tumor arose from the testis exophytically and was diagnosed as a thecoma histopathologically. Ovarian thecoma-fibroma group tumors are closely associated with Gorlin syndrome or with abnormalities in PTCH, a candidate gene for the syndrome. The occurrence of an extremely rare testicular thecoma in this case (the second in the literature) suggests that such an etiological association may also exist in the pathogenesis of testicular tumors.

Abstract
BACKGROUND AND PURPOSE Much interest is currently being focused on the anti-nociceptive effects mediated by nicotinic acetylcholine (nACh) receptors, including their location and mechanism of action. The purpose of this study was to elucidate these issues using 5-iodo-3-(2(S)-azetidinylmethoxy)pyridine (5IA), a nACh receptor agonist, and [(125)I]5IA. EXPERIMENTAL APPROACH We partially ligated the sciatic nerve of Sprague-Dawley rat to induce neuropathic pain [Seltzer's partial sciatic nerve ligation (PSL) model]. We then examined the changes in nACh receptor density in the CNS using [(125)I]5IA autoradiography and the involvement of nACh receptors in anti-nociceptive effects in the region where changes occurred. KEY RESULTS Autoradiographic studies showed that the accumulation of [(125)I]5IA and the number of nACh receptors in the thalamus of PSL rats were increased about twofold compared with those in the sham-operated rats. No change was observed in other brain regions. Rats injected in the ventral posterolateral thalamic nucleus (VPL) with 5IA demonstrated a significant and dose-dependent anti-allodynic effect and this effect was completely antagonized by mecamylamine, injected with 5IA, into the VPL. The blockade of nACh receptors in the VPL by mecamylamine decreased by 70% the anti-allodynic effect of 5IA, given i.c.v. Moreover, mecamylamine given intra-VPL by itself, induced significant hyperalgesia. CONCLUSIONS AND IMPLICATIONS Our findings suggest that the nACh receptors expressed in the VPL play an important role in the anti-allodynic effects produced by exogenous and endogenous agonists.

Abstract
CD109 is a glycosylphosphatidylinositol (GPI)-anchored glycoprotein, whose expression is upregulated in squamous cell carcinomas of the lung, esophagus, uterus and oral cavity. CD109 negatively regulates transforming growth factor (TGF)-beta signaling in keratinocytes by directly modulating receptor activity. In this study, we further characterized CD109 regulation of TGF-beta signaling and cell proliferation. We found that CD109 is produced as a 205 kDa glycoprotein, which is then processed in the Golgi apparatus into 180 kDa and 25 kDa proteins by furin (furinase). 180 kDa CD109 associated with GPI-anchored 25 kDa CD109 on the cell surface and was also secreted into the culture medium. To investigate whether furinase cleavage of CD109 is necessary for its biological activity, we mutated arginine 1273 in the CD109 furinase cleavage motif (amino acid 1270-RRRR-1273) to serine (R1273S). Interestingly, CD109 R1273S neither significantly impaired TGF-beta signaling nor affected TGF-beta-mediated suppression of cell growth, although it was expressed on the cell surface as a 205 kDa protein. Consistent with this finding, the 180 kDa and 25 kDa CD109 complex, but not CD109 R1273S, associated with the type I TGF-beta receptor. These findings indicate that processing of CD109 into 180 kDa and 25 kDa proteins by furin, followed by complex formation with the type I TGF-beta receptor is required for the regulation of TGF-beta signaling in cancer cells and keratinocytes.

Abstract
BACKGROUND Hereditary neuralgic amyotrophy (HNA), also known as hereditary brachial plexus neuropathy, has phenotypic and genetic heterogeneity. Mutations in the septin 9 (SEPT9) gene were recently identified in some HNA patients. The phenotypic spectrum of HNA caused by SEPT9 mutations is not well known. OBJECTIVE To characterise the phenotype of a large family of HNA patients with the SEPT9 R88W mutation. METHODS We report clinical, electrophysiological, neuroimaging and genetic findings of six HNA patients from a Japanese family. RESULTS All 17 neuropathic episodes identified were selectively and asymmetrically distributed in the upper-limb nerves. Severe pain was an initial symptom in 16 episodes (94%). Motor weakness occurred in 15 (88%) and sensory signs in 10 (59%). A minor dysmorphism, hypotelorism, was seen in all. Nerve conduction studies revealed focal demyelination as well as prominent axonal degeneration changes. Needle electromyography revealed chronic neurogenic patterns only in the upper limbs. An MRI study showed a gadolinium-enhanced brachial plexus. The missense mutation c.262C>T; p.R88W was found in exon 2 of SEPT9 in all patients. CONCLUSIONS The SEPT9 R88W mutation in this family causes selective involvement of the brachial plexus and upper-limb nerves. Wider and more universal recognition of clinical hallmarks and genetic counselling are of diagnostic importance for HNA caused by the SEPT9 mutation.

Abstract
e17020 Background: Superselective intra-arterial chemotherapy via a superficial temporal artery (HFT method) has become feasible for daily concurrent radiotherapy and chemotherapy for head and neck cancer. We used this novel method for head and neck cancer, and evaluated its efficacy. Treatment consisted of superselective intra-arterial infusions (docetaxel total 60 mg/m2, cisplatin total 100 mg/m2) and concurrent radiotherapy (total 40 Gy) for 4 weeks as preoperative therapy. Thirty-five patients with stage III and IV oral cancer underwent surgery after this treatment, of whom pathological complete response (CR) was obtained in 31 (88.6%). In this study, the possibility of organ preservation in cases of advanced head and neck cancer was evaluated based on this result. Methods: Eligibility included T3 or T4 squamous cell carcinoma of head and neck. Treatment consisted of superselective intra-arterial infusions (docetaxel, total 60 mg/m2, cisplatin, total 150 mg/m2) and concurrent radiotherapy (total 60 Gy) for 6 weeks. Organ preservation was demonstrated in cases when the biopsy specimen of the primary lesion showed grade 3 (non-viable tumor cells present) or grade 4 (no tumor cells present) after the completion of all treatments. Results: Thirty two patients (21 male and 11 female) were eligible for evaluation. A relapse was detected in 11 cases (34.4%): primary sites, 7 cases (21.9%); cervical lymph node and distant metastasis, 2 cases (6.3%); primary site and distant metastasis, 1 case (3.1%); cervical lymph node, 1 case (3.1%). Seven patients (21.9%) died. The Kaplan-Meier method was used to estimate the 3-year and 5-year survival rates, which were 81.3% and 78.1%, respectively, and the 3-year and 5-year locoregional control rates, which were 68.8% and 64.5%, respectively. No major complications such as cerebral infarctions or other neurological complications developed in any patient. Conclusions: These results of the present study demonstrate that this is a promising new treatment strategy for advanced head and neck cancer, thus contributing to patients’ QOL. No significant financial relationships to disclose.

Abstract
Comparison of the use of indirect immunofluorescence assay (IFA), immunochromatography assay (ICA-BD) and reverse transcription-polymerase chain reaction (RT-PCR) for detecting human respiratory syncytial virus (HRSV) in 306 nasopharyngeal aspirates samples (NPA) was performed in order to assess their analytical performance. By comparing the results obtained using ICA-BD with those using IFA, we found relative indices of 85.0% for sensitivity and 91.2% for specificity, and the positive (PPV) and negative (NPV) predictive values were 85.0% and 91.2%, respectively. The relative indices for sensitivity and specificity as well as the PPV and NPV for RT-PCR were 98.0%, 89.0%, 84.0% and 99.0%, respectively, when compared to the results of IFA. In addition, comparison of the results of ICA-BD and those of RT-PCR yielded relative indices of 79.5% for sensitivity and 95.4% for specificity, as well as PPV and NPV of 92.9% and 86.0%, respectively. Although RT-PCR has shown the best performance, the substantial agreement between the ICA-BD and IFA results suggests that ICA-BD, also in addition to being a rapid and facile assay, could be suitable as an alternative diagnostic screening for HRSV infection in children.

Abstract
Prothymosin-alpha (ProTalpha) causes a switch in cell death mode from necrosis to neurotrophin-reversible apoptosis in primary cultured cortical neurons. In the present study, post-ischemic administration (3 or 24 h, intravenously) of recombinant mouse ProTalpha without neurotrophins completely prevented ischemia-induced retinal damage accompanying necrosis and apoptosis, as well as dysfunction assessed by electroretinogram. Treatments with anti-erythropoietin (EPO) or brain-derived neurotrophic factor (BDNF) immunoglobulin G (IgG) reversed ProTalpha-induced inhibition of apoptosis. ProTalpha upregulated retinal EPO and BDNF levels in the presence of ischemia. Moreover, intravitreous administration of anti-ProTalpha IgG or an antisense oligodeoxynucleotide for ProTalpha accelerated ischemia-induced retinal damage. We also observed that ischemia treatment caused a depletion of ProTalpha from retinal cells. Altogether, these results suggest that the systemic administration of ProTalpha switches ischemia-induced necrosis to apoptosis, which in turn is inhibited by neurotrophic factors upregulated by ProTalpha and ischemia. ProTalpha released upon ischemic stress was found to have a defensive role in retinal ischemia.
