Abstract
PURPOSE/OBJECTIVE(S) The combination of accelerated hyperfractionated thoracic radiotherapy (AHF-TRT) of 45 Gy and concurrent chemotherapy is the standard treatment for limited-stage small-cell lung cancer (LS-SCLC). However, the optimal dose and fractionation remain controversial. We herein report the results of a phase II study investigating the utility of dose escalation to 54 Gy on AHF-RT for LS-SCLC. MATERIALS/METHODS We enrolled patients ≤80 years old with treatment-naïve confirmed LS-SCLC and an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2. The radiation dose was 54 Gy delivered in 36 fractions in 18 treatment days over 3.6 weeks. The chemotherapy regimens were PE (cisplatin and etoposide)- or CE (carboplatin and etoposide)-based. AHF-TRT was given in 2 phases: patients initially received 36 Gy to the gross tumor plus uninvolved mediastinal nodes, followed by a boost to the gross tumor of 18 Gy. All patients were treated with three-dimensional conformal radiation therapy with multiple fields to reduce the elevated dose volume to the surrounding tissues, such as the lungs and esophagus, as much as possible. All patients were evaluated for the overall survival (OS), progression-free survival (PFS), and non-hematological toxicity. RESULTS Between 2013 and 2016, a total of 13 patients were enrolled in the present study. All the patients were assessable for the response and toxicity. The median age was 67 (range, 54-78) years old, and 9 patients were male, while 4 were female. Twelve patients had a ECOG performance status of 0. The numbers of patients with Stage IIA, IIB, IIIA, and IIIB disease were one, one, eight, and three, respectively. The median follow-up for all patients was 79 (range, 13-107) months, and that for surviving patients was 90 (range, 79-107) months. The patterns of failure were locoregional-only recurrence in 0% (0 patients), both locoregional and distant in 15.4% (2 patients), and distant-only in 30.8% (4 patients). Recurrence from the elective nodal irradiation area was seen in 0% (0 patients). The 1-, 3-, 5-, and 7-year OS rates were 100%, 76.9%, 53.9%, and 44.9%, respectively, and the median OS was 83.0 months. The 1-, 3-, 5-, and 7-year PFS rates were 76.9%, 53.9%, 53.9%, and 44.9%, respectively, and the median PFS was 83.0 months. No patient experienced a grade ≥3 non-hematological adverse effect, such as esophagitis or pneumonitis, during treatment or follow-up. Grade 2 pneumonitis was observed in 2 patients (15.4%), Grade 2 esophagitis was observed in 12 patients (92.3%), and Grade 2 esophageal pain was observed in 2 patients (15.4%). CONCLUSION In this study, AHF-TRT of 54 Gy with concurrent PE- or CE-based regimens resulted in a good OS and PFS without increasing severe toxicity. Although this regimen needs to be evaluated in more patients to fully confirm its efficacy, these outcomes suggest that dose escalation to 54 Gy may be a promising radical treatment for LS-SCLC.

Abstract
PURPOSE/OBJECTIVE(S) Vulnerable patients receive a low-intensity, palliative treatment rather than the standard treatment. Defining vulnerability in terms of standard or reduced radiation intensity can result in appropriate radiotherapy for elderly cancer patients without excessive adverse events and poor outcomes. However, it is difficult to define vulnerability, because radiation oncologists hesitate to include vulnerable patients in clinical trials involving radical radiotherapy. We hypothesized that for elderly cancer patients without metastasis, vulnerability scores, obtained by geriatric assessment (GA), could help in predicting the reduction in radiation intensity determined by radiation oncologists based on their experience. MATERIALS/METHODS In this multicenter prospective study, we enrolled cancer patients (70 years or older) without metastasis. The reduction in radiation intensity was categorized into 3 groups as follows: i) standard schedule of radiotherapy, but conversion of irradiation fields, ii) standard irradiation fields, but converted schedule of radiotherapy, and iii) conversion of radiotherapy schedule and irradiation fields. Standard radiotherapy was defined as recommended doses and radiation fields according to the guidelines for the primary tumors analyzed. GA was performed by calculating geriatric 8 (G8) and vulnerable elders survey (VES-13) scores before radiotherapy and 3-5 and 8-16 weeks after completion of radiotherapy. The primary endpoint was to evaluate the correlation between vulnerability assessed by G8 and change in radiation intensity. RESULTS Between November 2020 and February 2022, 317 patients were included in this study at 13 centers in Japan. The median age was 77 (range, 70-90) years. The primary cancer sites were head and neck, esophagus, lungs, breasts, pancreas, bladder, uterus, and prostate in 63, 22, 62, 48, 6, 5, 26, and 85 patients, respectively. High-precision radiotherapy was performed for 199 patients (63%). Of the 31 patients (10%) whose radiation intensity was reduced, 14, 9, and 8 patients were provided i, ii, and iii category, respectively. Planned radiotherapy was completed for 312 patients (98%). G8 and VES-13 vulnerability scores were obtained for 201 and 61 patients, respectively, before radiotherapy. The mean G8 and VES-13 scores were 13.3 ± 2.4 and 1.8 ± 1.8, 12.9 ± 2.6 and 2.0 ± 2.0, and 13.4 ± 2.4 and 2.0 ± 1.9 before radiotherapy and 3-5 and 8-16 weeks after completion of radiotherapy, respectively. Multivariate analysis revealed that reduction in radiation intensity was significantly associated with vulnerability assessed using VES-13 (p < 0.001) but not G8 (p = 0.06). CONCLUSION An excellent completion rate was obtained for planned radiotherapy, and vulnerability assessed using VES-13, not G8, was associated with the reduction in intensity of radiotherapy.

Abstract
BACKGROUND Diverticulosis of the appendix is an uncommon clinical entity, and a preoperative diagnosis is often difficult. Herein we report an unusual case of appendiceal diverticulosis. CASE PRESENTATION A 72-year-old male was referred to our hospital to examine the cause of hematochezia. A colonoscopy study showed a protruding lesion resembling a submucosal tumor (SMT), approximately 20 mm in diameter, at the site around the appendiceal orifice of the cecum. An abdominal computed tomography and magnetic resonance imaging showed a cystic lesion at the appendiceal base. The lesion was clinically diagnosed as a cystic tumor of the appendix, but the possibility of a malignant tumor could not be excluded. Therefore, a laparoscopic ileocecal resection with lymph node dissection was performed. The pathological examination of the resected specimen revealed that the lesion was a diverticulum (pseudodiverticulum) occurring solitarily at the appendiceal base, in which the mucosal layer of the appendix was invaginated into the submucosa of the adjacent cecum, thus forming an SMT-like lesion. CONCLUSION To our knowledge, this is the first case report in the English literature showing that an appendiceal diverticulum can manifest as an SMT-like lesion in the cecum. This condition should be recognized as a differential diagnosis for such lesions.

Abstract
Background Spontaneous regression of hepatocellular carcinoma (HCC) is a rare event, and its clinicopathological features and underlying mechanism are not fully understood. Case presentation An 84-year-old female with hepatitis C virus infection and diabetes mellitus was referred to our hospital for further examination. Abdominal ultrasonography showed a 3.4-cm solid tumor with a heterogeneous irregular center and no fibrous capsule in liver segment 8 (S8). An enhanced computed tomography (CT) scan revealed a tumor in S8 with heterogeneous enhancement in the arterial phase and washed out insufficiently in the portal and equilibrium phase. The enhanced pattern on magnetic resonance imaging was similar to that of CT. Although the imaging findings were not typical for HCC, liver resection (S8) was performed with HCC as the most probable diagnosis. Histopathological examination of the resected specimen showed that the tumor was well to moderately differentiated HCC with unique features. Approximately half of the tumor was composed of well-differentiated HCC that was focally accompanied by dense lymphocyte infiltration. The other half of the tumor was fibrotic tissue that resembled an inflammatory pseudotumor. Several foci of moderately differentiated HCC were scattered within the tumor with a nodule-in-nodule appearance, and the foci totally showed coagulative necrosis. On immunostaining, lymphocytes in the tumor stroma were positive for CD8 and programmed death 1. The expression of programmed death-ligand 1 was observed in carcinoma cells and macrophages specifically within the lymphocyte-rich area of HCC. Conclusions We consider this case representative of spontaneous regression of HCC, and the immune response against HCC might contribute to tumor regression, leading to complex histopathological appearances. This case may provide insight into the mechanism of spontaneous regression of HCC.

Abstract
Background Heterotopic ossification (HO) is the formation of osseous tissue outside the skeleton. HO in malignant tumors of the digestive tract is extremely rare, as is ossification in metastatic lesions from HO-negative digestive tract tumors. Regarding the pathogenesis of HO, two theories have been proposed. The first is that the osteoblastic metaplasia of tumor cells (driven by the epithelial-mesenchymal transition, EMT) results in HO, and the second is that factors secreted by cancer cells lead to the metaplasia of stromal pluripotent cells into osteoblasts. However, the osteogenic mechanisms remain unclear. Case presentation An 83-year-old Japanese woman underwent low anterior rectal resection for rectal cancer before presentation at our institution, in June 2018. The final diagnosis was stage IIB rectal adenocarcinoma (T4aN0M0). Histological examination did not reveal HO in the primary tumor. Thirteen months after the operation, a solitary metastatic lesion in the brain 20 mm in size and a solitary metastatic lesion in a right axillary lymph node 20 mm in size were diagnosed. The patient was treated with gamma-knife therapy for the brain metastasis. One month later, she was referred to our institution. She underwent lymph node resection. Histological examination revealed that most portions of the affected lymph node were occupied by metastatic tumor cells and that central necrosis and four small ossified lesions without an osteoblast-like cell rim were present in the peripheral region. Immunohistochemical analysis showed tumor cells positive for BMP-2, osteonectin, osteocalcin, AE1/AE3, TGF-β1, Gli2, Smad2/3, and CDX2 and negative for nestin, CD56, and CK7. Conclusion This is the first English case report of HO in a metachronous metastatic lymph node after the curative resection of HO-negative rectal cancer. Unlike HO lesions in past reports, the HO lesion did not show peripheral osteoblast-like cells, and the immunohistochemical findings indicated that the present case resulted from the EMT.

Abstract
Interaction cross sections for ^{42-51}Ca on a carbon target at 280 MeV/nucleon have been measured for the first time. The neutron number dependence of derived root-mean-square matter radii shows a significant increase beyond the neutron magic number N=28. Furthermore, this enhancement of matter radii is much larger than that of the previously measured charge radii, indicating a novel growth in neutron skin thickness. A simple examination based on the Fermi-type distribution, and mean field calculations point out that this anomalous enhancement of the nuclear size beyond N=28 results from an enlargement of the core by a sudden increase in the surface diffuseness of the neutron density distribution, which implies the swelling of the bare ^{48}Ca core in Ca isotopes beyond N=28.

Abstract
Background Lymphoepithelioma-like carcinomas (LELCs), especially colorectal cancers (CRCs), are uncommon pathological phenotypes generally associated with poor aggressiveness and a preferable prognosis. However, PD-L1 overexpression in CRCs is associated with poor outcomes. We report a case of moderately differentiated adenocarcinoma with PD-L1 overexpression, an LELC component, and Crohn’s-like lymphoid reaction (CLR) presenting with extreme locoregional aggression and complete remission with chemotherapy after noncurative excision. Case presentation A 69-year-old man was referred to our hospital for abdominal fullness and pain. Computed tomography (CT) showed a circumferential tumor in the ascending colon, accompanied by bulky swollen lymph nodes. Under the preoperative diagnosis of T4N2M1 (lymph nodes) ascending colon cancer, we performed a right hemicolectomy; however, paracaval and parailiac vein lymph nodes were abandoned. Pathological findings showed moderate to poorly differentiated adenocarcinoma invading the subserosa accompanied by an LELC component invading the superficial muscularis propria. Lymph node metastases were found in a neighboring tumor and in retroperitoneal lymph nodes with glandular differentiation. No relation to microsatellite instability (MSI) or Epstein-Barr virus (EBV) was observed. In the component with glandular differentiation, PD-L1 overexpression was revealed. CLR findings were also observed. The tumor was diagnosed as T3N2M1 cancer that was moderately to poorly differentiated and had an LELC component. The patient was treated with chemotherapy, and the metastasized lymph nodes ultimately disappeared. He was alive without tumor recurrence 5-years post-operation. Conclusion This is a very rare case of moderately differentiated adenocarcinoma with PD-L1 overexpression and a heterogeneous LELC component that developed in the ascending colon. Unlike the previously reported weak aggressive properties of LELCs, the present case showed an extremely aggressive locoregional extent, but complete remission was finally achieved with chemotherapy. This type of LELC with CLR could be associated with a good response to chemotherapy and a good prognosis in CRC patients.

Abstract
OBJECTIVE A significant feature of tuberculosis (TB) in Japan is the fact that a high proportion of cases belong to the elderly population. Furthermore, previous reports have pointed out the delayed diagnosis of pulmonary TB in acute-care settings. We aimed to examine the clinical characteristics of pulmonary TB patients in an acute-care general hospital, particularly focusing on the elderly population. METHODS We retrospectively reviewed the medical records of patients with pulmonary TB who presented at our institution between May 2005 and December 2016. We described the overall clinical characteristics of these patients and compared them according to age. RESULTS Overall, 289 patients were eligible for the analysis, with a median age of 58 [42-73] years, and 29.4% being older than 70 years. Among the elderly patients, 42.4% were characterized by atypical presentation. CONCLUSION Our findings suggest that the elderly population tends to present as atypical cases lacking respiratory complaints, thereby being at a risk of misdiagnosis.

Abstract
Background Thus far, studies on Klebsiella pneumoniae carbapenemase (KPC)-producing organisms have only been reported in those with a history of foreign travel, and a specific Japanese KPC-producing isolate has not yet been reported. Case presentation We describe a Japanese patient, with no history of travel to foreign countries, admitted due to aspiration pneumonia, and a KPC-producing isolate detected in his sputum. Fortunately, his pneumonia resolved. His close contacts did not have a history of foreign travel, and the isolate was not detected in other patients. Conclusions The potential for KPC-producing organisms to become endemic in Japan is currently of great concern.

Abstract
Angelica keiskei Koidzumi (Ashitaba) is a large perennial herb that is native to the Pacific coast of Japan, and it has recently become popular as herbal medicine, dietary supplement and health food in Asian countries. The structures of various constituents isolated from Ashitaba such as chalcones, flavanones and coumarins have been precisely characterized, and many of them have bioactivities. A recent study clarified that Angelica keiskei exerts actions that lead to the prevention of thrombosis. Here, we introduce the possibility that ingesting Ashitaba could help to prevent thrombotic diseases.

Abstract
AST-120 is a specially synthesized carbonaceous adsorbent for oral use. It mainly adsorbs low to middle molecules in the alimentary tract. In the present study, AST-120 was administered to hepatic failure dogs, and blood metabolites were analyzed by high performance liquid chromatography (HPLC). Thirty adult mongrel dogs underwent posta-cavae (P-C) shunts with 40% and 70% hepatectomies. They were divided into two groups, the AST group (n= 19) and control group (n=11). The AST group received about 0.5 g/kg of the adsorbent intermittently with diet after the operation. The control group was fed the ordinary diet. Body weight, blood ammonia, plasma bile acids were measured, and blood metabolites were analyzed by the multi-column HPLC system. P-C shunt dogs with 70% hepatotectomies died within three months showing about 40–50% body weight loss. HPLC analysis of their plasma showed some specific peaks for middle molecules, about 3000–5000 daltons. After administration of the adsorbent, these peaks were not detected, so it was considered that these substances had been adsorbed.

Abstract
Angelica keiskei Koidzumi (Ashitaba) is a traditional folk medicine that is also regarded in Japan as a health food with potential antithrombotic properties. The ability of the major chalcones, xanthoangelol (XA) and 4-hydroxyderricin (4-HD) extracted from Ashitaba roots to inhibit platelet aggregation activity in vitro was recently determined. However, the anti-platelet activities of Ashitaba chalcones in vivo have remained unclear. The present study examines the anti-platelet effects of Ashitaba exudate and its constituent chalcones using mouse tail-bleeding models that reflect platelet aggregation in vivo. Ashitaba exudate and the major chalcone subtype XA, suppressed the lipopolysaccharide (LPS)-induced shortening of mouse tail bleeding. However, trace amounts of other Ashitaba chalcone subtypes including xanthoangelols B (XB), D (XD), E (XE) and F (XF) did not affect tail bleeding. These results suggest that the major chalcone subtype in Ashitaba, XA, has anti-platelet-activities in vivo.

Abstract
We report a resected case with a pathological complete response(pCR)after neoadjuvant chemotherapy for borderline resectable pancreatic cancer(BRPC). A 67-year-old woman who had been treated for type 2 diabetes mellitus in our hospital presented with an exacerbation of diabetes. An abdominal CT scan confirmed a hypovascular mass in the pancreas body consistent with BRPC. After 3 courses of chemotherapy with gemcitabine plus nab-paclitaxel(GnP), her elevated DUPAN-2 level normalized. A follow up CT scan revealed that the tumor had decreased in size, and no distant metastasis was detected. Distal pancreatectomy with en-bloc celiac axis resection was performed. Histopathological examination of the resected specimens showed no evidence of residual cancer cells(pCR). The patient remains disease-free 8 months after surgery. Neoadjuvant GnP chemotherapy may be useful for BRPC.

Abstract
Although tyrosine kinase inhibitors (TKIs) have significantly improved the prognosis of chronic myeloid leukemia (CML), the ability of TKIs to eradicate CML remains uncertain and patients must continue TKI therapy for indefinite periods. In this study, we performed whole-exome sequencing to identify somatic mutations in 24 patients with newly diagnosed chronic phase CML who were registered in the JALSG CML212 study. We identified 191 somatic mutations other than the BCR-ABL1 fusion gene (median 8, range 1–17). Age, hemoglobin concentration and white blood cell counts were correlated with the number of mutations. Patients with mutations ⩾6 showed higher rate of achieving major molecular response than those<6 (P=0.0381). Mutations in epigenetic regulator, ASXL1, TET2, TET3, KDM1A and MSH6 were found in 25% of patients. TET2 or TET3, AKT1 and RUNX1 were mutated in one patient each. ASXL1 was mutated within exon 12 in three cases. Mutated genes were significantly enriched with cell signaling and cell division pathways. Furthermore, DNA copy number analysis showed that 2 of 24 patients had uniparental disomy of chromosome 1p or 3q, which disappeared major molecular response was achieved. These mutations may play significant roles in CML pathogenesis in addition to the strong driver mutation BCR-ABL1.

Abstract
In this research, we analyzed the main sequence types (ST) and ST complexes of human- and chicken-derived isolates of Campylobacter jejuni in Japan by using multilocus sequence typing (MLST). We also analyzed lipooligosaccharide biosynthesis locus classes (LOS locus classes) and the numbers of isolates carrying genes coding resistance factors against various antibiotics, and observed their relationships. ST-21 complex was the main ST complex in isolates from humans (n = 38) and chickens (n = 25). None of the isolates showed resistance to imipenem, chloramphenicol, or erythromycin. Few isolates were resistant to ampicillin and streptomycin (1.3%-15%), whereas many showed resistance to tetracycline, ciprofloxacin, and nalidixic acid (38%-48%). Among the ST-21 complex isolates, ST4526 was detected at a very high rate. Those isolates showed resistance to tetracycline and ciprofloxacin, and were susceptible to ampicillin. Among the chicken-derived isolates, 37 of the 38 isolates that showed resistance to ciprofloxacin and nalidixic acid had threonine to isoleucine amino acid substitution in GyrA at codon 86 (T86I). Among the human-derived isolates, 17 of the 47 isolates that showed resistance to ciprofloxacin and 16 of the 48 isolates that showed resistance to nalidixic acid did not have T86I amino acid mutations in GyrA. The human-derived ST-21 complex isolates were classified into LOS locus classes A, B, C, D, and E. The chicken-derived ST-21 complex isolates, with the exception of one isolate, were all classified into LOS locus classes C and D. Among chicken-derived isolates, the most prevalent was ST51 (ST-443 complex) (10 isolates) and all of those were LOS locus class E.

Abstract
We present a statistical analysis of the first four seasons from a "second-generation" microlensing survey for extrasolar planets, consisting of near-continuous time coverage of 8 deg2 of the Galactic bulge by the OGLE, MOA, and Wise microlensing surveys. During this period, 224 microlensing events were observed by all three groups. Over 12% of the events showed a deviation from single-lens microlensing, and for ~1/3 of those the anomaly is likely caused by a planetary companion. For each of the 224 events we have performed numerical ray-tracing simulations to calculate the detection efficiency of possible companions as a function of companion-to-host mass ratio and separation. Accounting for the detection efficiency, we find that 55 - 22 + 34 % of microlensed stars host a snowline planet. Moreover, we find that Neptunes-mass planets are ~ 10 times more common than Jupiter-mass planets. The companion-to-host mass ratio distribution shows a deficit at q ~ 10-2, separating the distribution into two companion populations, analogous to the stellar-companion and planet populations, seen in radial-velocity surveys around solar-like stars. Our survey, however, which probes mainly lower-mass stars, suggests a minimum in the distribution in the super-Jupiter mass range, and a relatively high occurrence of brown-dwarf companions.

Abstract
Streptococcal toxic shock syndrome (TSS) is a systemic illness usually caused in the setting of infection by group A Streptococcus (GAS). The primary infections are often invasive infections of the respiratory tract or necrotizing infections of the skin and soft tissue, but some infections occur without relevant focus. GAS vaginitis is a rare condition among adult women and is accordingly thought to be uncommon as a cause of streptococcal TSS. Here we report the cases of two postmenopausal women with streptococcal TSS secondary to GAS vaginitis, one aged 55 and one aged 60. Both came to our emergency department with complaints or symptoms of abdominal pain, fever, hypotension, and multi-organ failure. In both cases, the relevant factor associated with streptococcal infection was a recent episode of GAS vaginitis. Both underwent fluid management and 14 days of antibiotic treatment and fully recovered without complications. Vaginitis was likely to be the primary infectious trigger of TSS in these two cases. Intrauterine device insertion, endometrial biopsy, and post-partum state have all been previously reported in TSS patients, and the female genital tract has been described as a portal of entry.

Abstract
Boron neutron capture therapy (BNCT) is high linear energy transfer (LET) radiation and tumor-selective radiation that does not cause serious damage to the surrounding normal tissues. BNCT might be effective and safe in patients with inoperable, locally advanced head and neck cancers, even those that recur at previously irradiated sites. However, carotid blowout syndrome (CBS) is a lethal complication resulting from malignant invasion of the carotid artery (CA); thus, the risk of CBS should be carefully assessed in patients with risk factors for CBS after BNCT. Thirty-three patients in our institution who underwent BNCT were analyzed. Two patients developed CBS and experienced widespread skin invasion and recurrence close to the carotid artery after irradiation. Careful attention should be paid to the occurrence of CBS if the tumor is located adjacent to the carotid artery. The presence of skin invasion from recurrent lesions after irradiation is an ominous sign of CBS onset and lethal consequences.

Abstract
OBJECTIVES About 160 patients in Japan were infected with dengue virus by mosquito's bites in the summer and autumn of 2014. In this report, I describe a case of occupational dengue virus infection by needle-stick injury from the 1990s to alert health-care workers to the fact that dengue virus is among the causative agents responsible for occupational infectious disease even in Japan. CASE A Japanese female in her thirties, a nurse at our hospital in Tokyo, was admitted to our hospital in January 1992 three days after the onset of fever, headache, and general malaise. She had never been overseas. Five days before the onset of her symptoms, she had pricked her finger with an injection needle used to draw blood from a febrile patient infected with dengue virus. She was diagnosed with dengue virus infection based on three findings: detection of the dengue virus genome in serum, isolation of dengue virus from serum, and serum samples positive for IgM antibodies against dengue virus. CONCLUSIONS The patient contracted dengue virus infection via a needle-stick injury at our hospital. Although this occurred more than two decades ago, in 1992, health-care workers should still be mindful of the risk of dengue virus infection via needle-stick injury even in Japan.

Abstract
A 61-year-old woman was admitted for long-lasting fever and recurrent opportunistic infections during the treatment of SLE. She had been diagnosed as SLE and type-IV nephritis based on a renal biopsy and serological findings. A colonoscopy and liver biopsy revealed disseminated Mycobacterium avium complex infection. Human immunodeficiency virus (HIV) infection status was then examined and found to be positive. From the clinical course, the first symptoms were inferred to have been those of HIV infection.

Abstract
Using gravitational microlensing, we detected a cold terrestrial planet orbiting one member of a binary star system. The planet has low mass (twice Earth's) and lies projected at ~0.8 astronomical units (AU) from its host star, about the distance between Earth and the Sun. However, the planet's temperature is much lower, <60 Kelvin, because the host star is only 0.10 to 0.15 solar masses and therefore more than 400 times less luminous than the Sun. The host itself orbits a slightly more massive companion with projected separation of 10 to 15 AU. This detection is consistent with such systems being very common. Straightforward modification of current microlensing search strategies could increase sensitivity to planets in binary systems. With more detections, such binary-star planetary systems could constrain models of planet formation and evolution.

Abstract
Subjective adverse reactions to metronidazole were analyzed in 111 patients with amebiasis. Metronidazole was administered to 36 patients at a daily dose of 2250 mg and 75 patients at daily doses lower than 2250 mg. The reactions reported included nausea without vomiting in 11 (9.9%) patients, nausea with vomiting in 2 (1.8%), dysgeusia in 2 (1.8%), diarrhea in 1 (0.9%), headache in 1 (0.9%), numbness in 1 (0.9%), dizziness in 1 (0.9%), urticaria in 1 (0.9%), exanthema in 1 (0.9%), and discomfort in 1 (0.9%). Nausea was reported by 28% (10/36) of the patients receiving metronidazole at a daily dose of 2250 mg and 4% (3/75) of the patients receiving lower daily doses. The duration of the metronidazole administration in days was not associated with the appearance of nausea. No life-threatening adverse reactions were identified, and good clinical therapeutic effects were observed in 96% (107/111) of the patients. While metronidazole appears to be a safe anti-protozoal agent for patients with amebiasis, our results indicate that a daily metronidazole dose of 2250 mg is excessive for amebiasis, as it often induces nausea.

Abstract
We demonstrate spin injection into superconducting Nb by employing a spin absorption technique in lateral spin valve structures. Spin currents flowing in a nonmagnetic Cu channel are preferably absorbed into Nb due to its strong spin-orbit interaction, the amount of which dramatically changes below or above the superconducting critical temperature (TC). The charge imbalance effect observed in the Cu/Nb interface ensures that superconducting Nb absorbs pure spin currents even below TC. Our analyses based on the density of states calculated using the Usadel equation can well reproduce the experimental results, implying that the strong spin-orbit interaction of Nb is still effective for the spin absorption even below TC. Most importantly, our method allows us to determine the intrinsic spin relaxation time in the superconducting Nb, which reaches more than 4 times greater than that in the normal state.

Abstract
We herein report the case of 41-year-old homosexual man who presented to our hospital with typical acute retroviral syndrome. Complications of bilateral facial nerve palsy and appendicitis appeared eight days after admission. The bilateral facial nerve palsy spontaneously recovered one month later; however, the appendicitis required surgical intervention. To our knowledge, this is the first reported case of appendicitis related to acute retroviral syndrome.
