Abstract
We report the direct observation of muon neutrino interactions with the SND@LHC detector at the Large Hadron Collider. A dataset of proton-proton collisions at sqrt[s]=13.6 TeV collected by SND@LHC in 2022 is used, corresponding to an integrated luminosity of 36.8 fb^{-1}. The search is based on information from the active electronic components of the SND@LHC detector, which covers the pseudorapidity region of 7.2<η<8.4, inaccessible to the other experiments at the collider. Muon neutrino candidates are identified through their charged-current interaction topology, with a track propagating through the entire length of the muon detector. After selection cuts, 8 ν_{μ} interaction candidate events remain with an estimated background of 0.086 events, yielding a significance of about 7 standard deviations for the observed ν_{μ} signal.

Abstract
The OPERA experiment was designed to discover the vτ appearance in a vμ beam, due to neutrino oscillations. The detector, located in the underground Gran Sasso Laboratory, consisted of a nuclear photographic emulsion/lead target with a mass of about 1.25 kt, complemented by electronic detectors. It was exposed from 2008 to 2012 to the CNGS beam: an almost pure vμ beam with a baseline of 730 km, collecting a total of 1.8·1020 protons on target. The OPERA Collaboration eventually assessed the discovery of vμ→vτ oscillations with a statistical significance of 6.1 σ by observing ten vτ CC interaction candidates. These events have been published on the Open Data Portal at CERN. This paper provides a detailed description of the vτ data sample to make it usable by the whole community.

Abstract
The OPERA experiment was designed to study ν_{μ}→ν_{τ} oscillations in the appearance mode in the CERN to Gran Sasso Neutrino beam (CNGS). In this Letter, we report the final analysis of the full data sample collected between 2008 and 2012, corresponding to 17.97×10^{19} protons on target. Selection criteria looser than in previous analyses have produced ten ν_{τ} candidate events, thus reducing the statistical uncertainty in the measurement of the oscillation parameters and of ν_{τ} properties. A multivariate approach for event identification has been applied to the candidate events and the discovery of ν_{τ} appearance is confirmed with an improved significance level of 6.1σ. |Δm_{32}^{2}| has been measured, in appearance mode, with an accuracy of 20%. The measurement of the ν_{τ} charged-current cross section, for the first time with a negligible contamination from ν[over ¯]_{τ}, and the first direct evidence for the ν_{τ} lepton number are also reported.

Abstract
The findings at CT in 11 patients with primary non-Hodgkin lymphoma (NHL) of the maxillary sinus were compared with the CT findings in 21 patients with squamous cell carcinoma (SCC) of the maxillary sinus. In NHL, the segmental bone destruction was in alignment with the bony wall with a massive tumor infiltration into the neighboring structures. In contrast, all patients with SCC were characterized by a soft tissue mass with aggressive bone destruction. About half of the patients with NHL had cervical lymphadenopathy. Post-treatment recalcification of previous bone destruction was seen in 4 out of 5 NHL patients on follow-up CT. In the patients with SCC, only a few had metastatic lymphadenopathy, and no recalcification occurred after treatment. CT is therefore of importance in differentiating NHL from SCC of the maxillary sinus.

Abstract
Five patients with a second maxillary cancer (squamous cell carcinoma), which developed 6 to 17 years after initial treatment for the first cancer on the opposite side, were compared with 21 control cases with a primary cancer on the basis of computed tomography (CT) findings. Generally, the second cancer was found at an earlier stage. The specific CT findings of early sinus carcinoma were uneven soft tissue distribution in the antrum and tumor permeation with bone fragments remaining at the original tumor site. These findings may be helpful for distinguishing this cancer from benign chronic sinusitis and/or other malignant sinus disease. The pterygoid process, medial bony wall, and ethmoid sinus had a tendency to be spared in most of the 5 patients with second maxillary cancer compared to the 21 control cases.

Abstract
A 10-year-old, female, mongrel showed hemorrhage from vulva. By magnetic resonance image (MRI) and endoscopic examination, a multipapillary mass with a grape-like appearance was found around the urethral opening. Histologically, the mass consisted of variable-sized round-, spindle-to-polygonal-shaped tumor cells including many multinuclear cells. Mitotic figures were also frequently observed. In some areas, that tumor cells were loosely arranged, with intercellular myxoid components. immunohistochemically, these tumor cells were strongly positive for vimentin and focally positive for desmin but negative for myoglobin. Thus, the case was diagnosed as a relatively poorly differentiated botryoid rhabdomyosarcoma by the macroscopic, histopathologic, and immunohistochemical identification. This is the first report of botryoid rhabdomyosarcoma developing in the vagina of a dog.

Abstract
A 6-year-old male cross-breed rabbit ( Oryctolagus cuniculus) was presented with lameness and severe swelling from the right shoulder to brachium. On 16-detector helical computed tomography images of the amputated right forelimb after being fixed in formalin, evident proliferative and destructive lesions of bone were observed. On histologic examination, the tumor was composed of proliferating neoplastic cells that resembled histiocytes, with abundant osteoid production. A large number of multinucleated giant cells were found throughout. This case was diagnosed as osteosarcoma by clinical, radiographic, and histologic findings. This is a rare case report of osteosarcoma in a rabbit consistent with canine predilection sites.

Abstract
The OPERA experiment was designed to search for ν_{μ}→ν_{τ} oscillations in appearance mode, i.e., by detecting the τ leptons produced in charged current ν_{τ} interactions. The experiment took data from 2008 to 2012 in the CERN Neutrinos to Gran Sasso beam. The observation of the ν_{μ}→ν_{τ} appearance, achieved with four candidate events in a subsample of the data, was previously reported. In this Letter, a fifth ν_{τ} candidate event, found in an enlarged data sample, is described. Together with a further reduction of the expected background, the candidate events detected so far allow us to assess the discovery of ν_{μ}→ν_{τ} oscillations in appearance mode with a significance larger than 5σ.

Abstract
We report the clinical outcome and findings at second-look arthroscopy of 216 patients (mean age 25 years (11 to 58)) who underwent anterior cruciate ligament (ACL) reconstruction or augmentation. There were 73 single-bundle ACL augmentations (44 female, 29 male), 82 double-bundle ACL reconstructions (35 female, 47 male), and 61 single-bundle ACL reconstructions (34 female, 27 male). In 94 of the 216 patients, proprioceptive function of the knee was evaluated before and 12 months after surgery using the threshold to detect passive motion test. Second-look arthroscopy showed significantly better synovial coverage of the graft in the augmentation group (good: 60 (82%), fair: 10 (14%), poor: 3 (4%)) than in the other groups (p = 0.039). The mean side-to-side difference measured with a KT-2000 arthrometer was 0.4 mm (-3.3 to 2.9) in the augmentation group, 0.9 mm (-3.2 to 3.5) in the double-bundle group, and 1.3 mm (-2.7 to 3.9) in the single-bundle group: the result differed significantly between the augmentation and single-bundle groups (p = 0 .013). No significant difference in the Lysholm score or pivot-shift test was seen between the three groups (p = 0.09 and 0.65, respectively). In patients with good synovial coverage, three of the four measurements used revealed significant improvement in proprioceptive function (p = 0.177, 0.020, 0.034, and 0.026). We conclude that ACL augmentation is a reasonable treatment option for patients with favourable ACL remnants. Cite this article: Bone Joint J 2014;96-B:1325–32

Abstract
Thrombin plays important roles in the pathology of intracerebral hemorrhage (ICH). The recruitment of activated microglia, accompanied by thrombin-induced phosphorylation of the mitogen-activated protein kinase (MAPK) family, contributes to ICH-associated neuron loss. Here we investigated the possibility that sesamin, a lignan of sesame seed oil, is a natural candidate as an inhibitor of microglial activation and MAPK pathways under ICH insults. Sesamin (30-100 μM) suppressed thrombin-induced nitric oxide (NO) production by primary-cultured rat microglia via inhibition of inducible NO synthase (iNOS) protein expression, independently of the antioxidative effect. Sesamin selectively inhibited p44/42 MAPK phosphorylation in the MAPK family (p38 and p44/42) involved in iNOS protein expression in primary-cultured rat microglia. An in vivo rat ICH model was prepared by intrastriatal injection of 0.20U collagenase type IV unilaterally. ICH evoked the phosphorylation of p44/42 MAPK, microglial proliferation with morphological change into the activated ameboid form, and neuron loss. The phosphorylation of p44/42 MAPK was inhibited by intracerebroventricular administration of 30-nmol sesamin. Sesamin prevented ICH-induced increase of microglial cells in the perihematomal area. Notably, ramified microglia, the resting morphology, were observed in brain sections of the animals administrated sesamin. Sesamin furthermore achieved neuroprotection in the perihematomal area but not in the hematomal center. These results suggest that sesamin is a promising natural product as a novel therapeutic strategy based on the regulation of microglial activities accompanied by the activated p44/42 MAPK pathway in ICH.

Abstract
Cystadenocarcinoma is a rare salivary gland tumour. Only a few case studies have provided pre-operative images of these tumours. This report demonstrates the case of a 28-year-old male with cystadenocarcinoma arising from an ectopic salivary gland with lymph node metastasis in the right upper neck. Ultrasound including Doppler images showed two masses with scant vascular flow. One was a hyperechoic mass enclosed within a low echoic cystic lesion and the other was a solid hypoechoic mass. Contrast enhancement CT scans demonstrated a ring enhanced mass and weakly homogeneous enhanced masses in the right upper neck. Dynamic studies showed increased enhancement in delayed phase CT that was the same as that in other malignant salivary gland tumours. Moderate to slightly high signal intensity was seen on T(1) weighted MR images and axial T(2) weighted MR images showed one heterogeneous mass in a high signal lesion and a moderate to high signal intensity mass. The authors discuss the pre-operative findings of ultrasound with Doppler imaging of this neoplasm, and CT findings including dynamic study images and MRI, comparing the findings with the post-operative pathological features of the tumour.

Abstract
99 Background: Focal therapy for prostate cancer could be a minimally invasive therapeutic option with the preservation of genitourinary function to reduce treatment associated complication under the appropriate selection of patients. We have reported the good predict ability to unilateral prostate cancer by extended prostate biopsy combined with transperineal and transrectal approaches (Eur Urol supple, 2009). Among the candidate ablative, brachytherapy which has been proved as a definitive therapy and applied worldwide has been thought to have potential for focal ablation due to its ability of dose and location adjustment by seed implantation under real-time monitoring. Based on the findings, focal therapy with hemiablation using I-125 seed implantation has been started in our instituion. The aim of study is to describe the initial experience of focal therapy for patients selected by extended biopsy and MRI findings. Methods: The eligible criteria for focal therapy to prostate cancer are as follows. Clinical stage is T2a or less. The positive cores of cancer are proven within unilateral lobe by extended prostate biopsy. There was no cancerous lesion in contralateral lobe by MRI. Gleason score in positive cores was 3 + 4 or less. Maximum cancer length was less than 5 mm. PSA value is less than 10 ng/mL. On the treatment, I-125 seeds were implanted to ablate the unilateral lobe with 160 Gy of the prescription dose. The protocol has been approved by the institutional ethics commit. Results: At present, 3 patients were enrolled in this study and underwent focal therapy with written informed consents. In all three cases, I-125 seeds implanted (number od seeds: 43, 39, and 37) to unilateral lobe without severe acute complication such as acute urinary retention. In one case that has been followed over 3months among the initial three cases, PSA values decreased to 2.07 mg/ml at 3 months after the seed implantation. Conclusions: To our knowledge, this is the first report about focal therapy by brachytherapy with hemiablative technique. In our initail experience, severe treatment associated complication has not been observed. No significant financial relationships to disclose.

Abstract
OBJECTIVE The aim of this study was to evaluate the outcome and complications of low-dose-rate brachytherapy (LDR-BT) for oral cancer according to comorbidity. METHODS The records of a total of 180 patients who received LDR-BT for T1-2N0M0 oral cancers between January 2005 and December 2007 were analysed. The comorbidities of the patients were retrospectively graded according to the Adult Comorbidity Evaluation-27, and the relationships between the comorbidity grades and survival, disease control and the incidence of complications were analysed. RESULTS The 2 year overall survival rates of patients with no comorbidity, Grade 1, Grade 2 and Grade 3 comorbidity were 87%, 85%, 76% and 65%, respectively, and the reduction in the survival rate according to comorbid severity was significant in a univariate analysis (p = 0.032) but not in a multivariate analysis including other clinical factors. Cause-specific survival, locoregional control and local control were not related to the comorbidity grade, or any other clinical factors. Grade 2 or 3 complications developed in 27% of the patients. The incidence of complications was unrelated to the comorbidity grade. CONCLUSION The disease control of oral cancer and the incidence of complications after LDR-BT were not related to comorbid severity. LDR-BT is a useful and safe treatment for patients regardless of the presence of severe comorbidity.

Abstract
Amebic colitis normally causes mucous and bloody diarrhea stool as predominant symptoms, thus leading to a course of chronic colitis. However, though rare, there exists a fulminating type that causes intestinal perforations due to wide necrosis of the large intestine. We encountered a case of fulminant amebic colitis that lead to death due to multiple large intestinal perforations. The patient was a 72-year-old female. The patient was admitted to our hospital with symptoms of fever, abdominal pain, and diarrhea. She continued to have a fever of over 38 degrees C and increased left abdominal pain. An abdominal computed tomography scan revealed free gas on the abdominal side of the kidney. Therefore, gastrointestinal perforations were diagnosed and surgery was performed. In surgery, many perforated parts were observed from the appendix to the descending colon, and subtotal colectomy was performed. However, sepsis and disseminated intravascular coagulation occurred, and the patient died on the eighth postoperative day.

Abstract
BACKGROUND The result of curative treatment for very elderly patients with tongue carcinoma has not been reported to date. We retrospectively reviewed the results of brachytherapy in 125 the patients aged over 75 years. METHODS The results of brachytherapy in 125 patients, 75 years old or older, with Stage I or II squamous cell carcinoma of the oral tongue were reviewed. The 125 cases consisted of 31 Stage I and 94 Stage II cases; 67 patients were under 80 years old and 58 were over 80 years old. All patients were treated using low-dose-rate brachytherapy ((198)Au/(222)Rn: 59 cases; (192)Ir: 38 cases; (226)Ra/(137)Cs: 28 cases). RESULTS None of the patients stopped treatment during the course of brachytherapy. The 3 year and 5 year control rates of the primary lesions were both 86%. Post-brachytherapy neck node metastasis was diagnosed in 43 cases and radical neck dissection was performed for 24 cases (21 of the 24 cases were under 80 years old). As a result, the 7 year disease-specific survival (DSS) rate for patients aged under 80 years old was 70% and 41% for those over 80 years old (p = 0.03). CONCLUSION The brachytherapy for elderly patients with tongue cancer was safe, and the control of the primary lesion was almost the same as in younger patients. However, modalities available to treat neck node metastasis are limited. More conservative surgical approaches combined with post-operative irradiation may be advocated for neck node metastasis for elderly patients with tongue cancer.

Abstract
BACKGROUND Positron emission tomography (PET)-computed tomography (CT) may be useful in the post-treatment follow-up of breast cancer patients. PURPOSE To assess the usefulness of (18)F-fluorodeoxyglucose (FDG) PET-CT (PET-CT) for postoperative monitoring of breast cancer patients. MATERIAL AND METHODS One hundred twenty-nine PET-CT studies performed on 55 female postoperative breast cancer patients (median age 56 years, range 36-86 years) were analyzed. The median interval between the PET-CT studies was 6 months (range 1-15 months). In order to determine the usefulness of serial PET-CT examinations in the postoperative follow-up of breast cancer patients, the PET-CT findings were compared with the physical findings, findings obtained by other imaging modalities, and the (18)F-FDG-PET (PET) findings. RESULTS The PET findings were negative in 4 metastatic bone lesions with a positive bone scan. The PET findings were also negative in 6 of 9 osteogenic bone metastases and one of 64 osteolytic bone lesions. There were 5 cases with false-positive of PET, which were determined to be areas of soft-tissue hyperactivity. All false-positive/-negative findings were corrected by the addition of CT. CONCLUSION The results of this study lend support to the clinical role of PET-CT in the postoperative follow-up/monitoring of breast cancer patients.

Stellar image and objective spectrum without coronagraphic suppression are also obtained as reference. By convolution of the coronagraphic image with the reference stellar spectrum, pseudo-objective spectra are synthesized. The difference between the observed and the synthesized pseudospectra reveals the distinctive features of planetary spectrum. We carry out laboratory demonstration of the proposed technique and show that the planetary spectrum is reconstructed.

Abstract
The arterial supply of the gallbladder usually arises from the right hepatic artery. Other origins include the left, proper, and common hepatic arteries. We report cases of the cystic artery arising from the superior mesenteric artery and arising from the dorsal pancreatic artery originating in turn from the superior mesenteric artery, as demonstrated by angiography and computed tomography.

Abstract
A total of 90 tumors from 85 domestic hamsters (70 Djungarian hamsters and 15 Syrian hamsters) were examined by histology. In the Djungarian hamsters, 64 neoplastic and 11 non-neoplastic lesions were identified, whereas 14 Syrian hamsters showed neoplastic disease, and one showed non-neoplastic disease. The Djungarian hamsters showed a high prevalence of neoplastic disease, similarly to laboratory Djungarian hamsters. In the Djungarian hamsters, almost all tumors were integumental, whereas hematopoietic tumors were the most common type in the Syrian hamsters. The most common integumental tumors in the Djungarian hamsters were mammary tumors, atypical fibromas and papillomas, and a spectrum of integumental tumors that have not been reported in laboratory Djungarian hamsters were identified. Most mammary tumors occurred in the females, whereas all atypical fibromas were observed in the males. In the Syrian hamsters, plasmacytomas and lymphomas were the most common tumors. The small number of Syrian hamsters in this study may reflect the low prevalence of spontaneous tumors seen in laboratory Syrian hamsters. The mean age of the affected hamsters was 19.8 months, which is relatively advanced. To our knowledge, this is the first comprehensive study of tumors in domestic hamsters.

Abstract
We report on a search for the doubly Cabibbo suppressed decay B+-->D*+pi0, based on a data sample of 657x10(6) BB pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We find no significant signal and set an upper limit of B(B+-->D*+pi0)<3.6x10(-6) at the 90% confidence level. This limit can be used to constrain the ratio between suppressed and favored B-->D*pi decay amplitudes, r<0.051, at the 90% confidence level.

Abstract
An 8-year-old, male, mongrel dog developed severe cough and anorexia and died within 3 months. Autopsy revealed an invasive grayish-white mass in the right kidney and multiple nodules in the lungs, thoracic wall, and spleen. Histologically, the renal mass and the other nodules were mainly composed of papillotubular structures lined by oval-to-polygonal pleomorphic cells. The cells were reactive with DBA, PNA, and UEA-1 lectins and positive for vimentin but negative for CD10 and high molecular weight cytokeratin. Because of its histological, histochemical, and immunohistochemical similarities with human collecting duct carcinoma (CDC), a diagnosis of renal collecting duct carcinoma with pulmonary, thoracic, and splenic metastases was established. To our knowledge, this is the first case report of CDC in animals.

Abstract
Using a 492 fb{-1} data sample collected near the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e{+}e{-} collider, we observe the decay B{0}-->ppK*0 with a branching fraction of (1.18{-0.25}{+0.29}(stat)+/-0.11(syst))x10{-6}. We study the decay dynamics of B{0}-->ppK*0 and compare with B{+}-->ppK*+. The K*0 meson is found to be almost 100% polarized (with a fraction of (101+/-13+/-3)% in the helicity zero state), while the K*+ meson has a (32+/-17+/-9)% fraction in the helicity zero state. The direct CP asymmetries for B{0}-->ppK*0 and B{+}-->ppK*+ are measured to be -0.08+/-0.20+/-0.02 and -0.01+/-0.19+/-0.02, respectively. In addition, we report improved measurements of the branching fractions B(B{+}-->ppK*+)=(3.38{-0.60}{+0.73}+/-0.39)x10{-6} and B(B{0}-->ppK{0})=(2.51{-0.29}{+0.35}+/-0.21)x10{-6}, which supersede our previous measurements.

Abstract
We present a measurement of the branching fraction B(D{s}{+}-->mu{+}nu{mu}) using a 548 fb{-1} data sample collected by the Belle experiment at the KEKB e{+}e{-} collider. The D{s} momentum is determined by reconstruction of the system recoiling against DKgammaX in events of the type e{+}e{-}-->D{s}{*}DKX, D{s}{*}-->D{s}gamma, where X represents additional pions or photons from fragmentation. This full-reconstruction method provides high resolution in the neutrino momentum and thus good background separation, equivalent to that achieved by experiments at the tau-charm factories. We obtain the branching fraction B(D{s}{+}-->mu{+}nu{mu})=[6.44+/-0.76(stat)+/-0.57(syst)]x10{-3}, implying a D{s} decay constant of f{D{s}}=[275+/-16(stat)+/-12(syst)] MeV.

Abstract
We report a study of the processes e+e- -->J/psiD*D[over](*). In J/psiD*D[over]* we observe a significant enhancement in the D*D[over]* invariant mass spectrum, which we interpret as a new charmoniumlike state and denote X(4160). The X(4160) parameters are M=(4156(-20)+25+/-15) MeV/c2 and Gamma=(139(-61)+111+/-21) MeV. We also report a new measurement of the X(3940) mass and width: M=(3942(-6)+7+/-6) MeV/c2 and Gamma=(37(-15)+26+/-8) MeV. The analysis is based on a 693 fb(-1) data sample recorded near the Upsilon(4S) resonance by the Belle detector at the KEKB asymmetric-energy collider.

Abstract
A distinct peak is observed in the pi +/- psi' invariant mass distribution near 4.43 GeV in B-->K pi +/- psi' decays. A fit using a Breit-Wigner resonance shape yields a peak mass and width of M=4433+/-4(stat)+/-2(syst) MeV and Gamma=45-13+18(stat)-13+30(syst) MeV. The product branching fraction is determined to be B(B 0-->K -/+Z+/-(4430)) x B(Z+/-(4430)-->pi+/-psi')=(4.1+/-1.0(stat)+/-1.4(syst)) x 10(-5), where Z+/-(4430) is used to denote the observed structure. The statistical significance of the observed peak is 6.5 sigma. These results are obtained from a 605 fb(-1) data sample that contains 657 x 10(6) BB pairs collected near the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric energy e+ e- collider.

Abstract
We search for the radiative penguin decays B_{s}{0}-->varphigamma and B_{s}{0}-->gammagamma in a 23.6 fb{-1} data sample collected at the Upsilon(5S) resonance with the Belle detector at the KEKB e{+}e{-} asymmetric-energy collider. We observe for the first time a radiative penguin decay of the B_{s}{0} meson in the B_{s}{0}-->varphigamma mode and we measure B(B_{s}{0}-->varphigamma)=(57_{-15}{+18}(stat)-11+12(syst))x10{-6}. No significant B_{s}{0}-->gammagamma signal is observed and we set a 90% confidence level upper limit of B(B_{s}{0}-->gammagamma)<8.7x10{-6}.

Abstract
We report a measurement of the CP-violating parameters in B;{0}-->K_{S}{0}K_{S}{0} decays based on a data sample of 657x10{6} BB[over ] pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e;{+}e{-} collider. In this Letter, one neutral B meson is fully reconstructed in the B;{0}-->K_{S}{0}K_{S}{0} decay mode, and the flavor of the accompanying B meson is identified by its decay products. The CP-violating parameters are measured from the asymmetry in the distributions of the proper-time interval between the two B decays: S_K_{S}{0}K_{S}{0}}=-0.38_{-0.77}{+0.69}(stat)+/-0.09(syst) and A_{K_{S}{0}K_{S}{0}}=-0.38+/-0.38(stat)+/-0.05(syst).
