A Pilot Study for Return of Individual Pharmacogenomic Results to Population-Based Cohort Study Participants. JMA J 2022; 5:177-189. [PMID: 35611229 PMCID: PMC9090545 DOI: 10.31662/jmaj.2021-0156] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Accepted: 12/01/2021] [Indexed: 11/25/2022] Open
Abstract
Introduction: Pharmacogenomic (PGx) testing results provide valuable information on drug selection and appropriate dosing, maximization of efficacy, and minimization of adverse effects. Although the number of large-scale, next-generation-sequencing-based PGx studies has recently increased, little is known about the risks and benefits of returning PGx results to ostensibly healthy individuals in research settings. Methods: Single-nucleotide variants of three actionable PGx genes, namely, MT-RNR1, CYP2C19, and NUDT15, were returned to 161 participants in a population-based Tohoku Medical Megabank project. Informed consent was obtained from the participants after a seminar on the outline of this study. The results were sent by mail alongside sealed information letter intended for clinicians. As an exception, genetic counseling was performed for the MT-RNR1 m.1555A > G variant carriers by a medical geneticist, and consultation with an otolaryngologist was encouraged. Questionnaire surveys (QSs) were conducted five times to evaluate the participants’ understanding of the topic, psychological impact, and attitude toward the study. Results: Whereas the majority of participants were unfamiliar with the term PGx, and none had undergone PGx testing before the study, more than 80% of the participants felt that they could acquire basic PGx knowledge sufficient to understand their genomic results and were satisfied with their potential benefit and use in future prescriptions. On the other hand, some felt that the PGx concepts or terminology was difficult to fully understand and suggested that in-person return of the results was desirable. Conclusions: These results collectively suggest possible benefits of returning preemptive PGx information to ostensibly healthy cohort participants in a research setting.

Enhancement and evaluation of a prescription audit system for direct oral anticoagulants using a check sheet. J Pharm Health Care Sci 2021; 7:22. [PMID: 34059144 PMCID: PMC8168308 DOI: 10.1186/s40780-021-00205-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Accepted: 04/08/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Renal function and use of concomitant medications should be carefully monitored in patients subjected to treatment with direct oral anticoagulants (DOACs); the dose should be individually designed for each patient. Owing to the complex therapeutic indications and dose reduction criteria, pharmacists exercise caution when determining the optimal dose for each patient. A DOAC check sheet has been developed that is automatically printed in the dispensing room at the same time as the prescription and can be used by pharmacists to dispense DOACs promptly and correctly. The purpose of this study was to evaluate the system for dispensing DOACs using a check sheet. METHODS The study was conducted at Tohoku University Hospital in Japan; prescriptions containing DOACs dispensed by the hospital pharmacists were evaluated. The DOAC check sheet described indications, dosage regimens, dose reduction criteria, and contraindications for each drug and included the patient's information. The check sheet was set to print automatically in the dispensing room at the same time as the prescription when an inpatient was prescribed DOACs. This check sheet was evaluated using a prescription survey and a questionnaire for pharmacists. RESULTS The usefulness of this check sheet for the correct use of DOACs was evaluated. There were four inquiries out of 642 (0.6%) prescriptions from pharmacists to physicians regarding DOAC prescriptions, such as the dose introduced before DOAC check sheet utilization, and there were 21 out of 905 (2.3%) prescriptions when the DOAC check sheet was used it, showing a significant increase (p = 0.0089). After the introduction of this sheet, overdoses of DOACs were identified at the time of dispensing. Of the 52 pharmacists who responded to the questionnaire, 51 (98%) stated that the check sheet was useful. CONCLUSION The use of the DOAC check sheet is likely to render safety to DOAC drug therapy for individual patients.

Abstract
We have recently have developed an in-situ multiple-channel depth distribution spectrometer (DDS) that can easily acquire on-site measurements of the depth distribution of specific radioactivities of Cs-134 and Cs-137 underground. Despite considerable improvements in the hardware developed for this device, the quantitative method for determining of radioactivities with this DDS device cannot yet achieve satisfactory performance for practical use. For example, this method cannot discriminate each γ-ray spectra of Cs-134 and Cs-137 acquired by the 20 thallium-doped caesium iodine CsI(Tl) scintillation crystal detectors of the DDS device from corresponding depth levels of underground soil. Therefore, we have applied deep learning neural network (DLNN) as a novel radiation measurement technique to discriminate the spectra and to determine the specific radioactivities of Cs-134 and Cs-137. We have developed model soil layers on a virtual space in Monte-Carlo based PHITS simulations and transported γ-ray radiation generated from a particular single soil layer or multiple layers as radiation sources; next, we performed PHITS calculations of those specific radioactivity measurements for each soil layer using DDS device based on machine learning via the DLNN algorithm. In this study, we obtained informative results regarding the feasibility of the proposal innovative radiation measurement method for further practical use in on-site applications.

Abstract
Background: The importance of pharmacovigilance in Japan is gradually being recognized. However, Japanese pharmacists’ knowledge of and perspectives on pharmacovigilance have been examined only in some areas of Japan. Objective: The objective of this study was to clarify the knowledge, attitudes, and practice regarding pharmacovigilance and adverse drug reaction (ADR) reporting among hospital pharmacists in Japan. Setting: A questionnaire survey among Japanese hospital pharmacists. Method: The questionnaire was distributed to 48 028 pharmacists during a 3-month period between January and March 2017. Main Outcome Measure: The prevalence of hospital pharmacists who understood pharmacovigilance and the ADR reporting system. Results: Of the respondents (response rate; 9.9% = 4760/48 028), 21.9% were <30 years of age, 27.3% were ≥50 years of age, and 46.7% were women. In response to the question “Have you ever heard of the term ‘pharmacovigilance’?,” 12.4%, 33.8%, and 47.4% answered “I understand what it is,” “I have heard of it, but I do not understand what it is,” and “I do not know what it is,” respectively. Pharmacists who understood the term “pharmacovigilance” were also more frequently acquainted with its associated terms and actions. And, 69.7% of respondents wished to acquire more information on pharmacovigilance and 50.9% did not have a personal history of ADR reporting. The most common reason for ADR nonreporting was “It was a well-known adverse drug reaction” (44.5%). Conclusions: Our results suggest that more aggressive promotion of pharmacovigilance and of the ADR reporting system among Japanese pharmacists is needed.

Middle-to long-term outcome after medial patellofemoral ligament reconstruction with Insall's proximal realignment for patellar instability. ASIA-PACIFIC JOURNAL OF SPORT MEDICINE ARTHROSCOPY REHABILITATION AND TECHNOLOGY 2019; 17:5-9. [PMID: 30984562 PMCID: PMC6444065 DOI: 10.1016/j.asmart.2019.02.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/08/2018] [Revised: 01/28/2019] [Accepted: 02/18/2019] [Indexed: 11/26/2022]
Abstract
Background Recently, medial patellofemoral ligament (MPFL) reconstruction has become a common, widely used procedure to treat patellar instability. However, few reports exist on the long-term outcome after MPFL reconstruction. We elucidated the middle- to long-term outcome after MPFL reconstruction with Insall’s proximal realignment. Methods: From 1999 to 2012, 42 knees of 32 patients who underwent MPFL reconstruction with Insall’s proximal realignment were reviewed with a minimum follow-up of five years. Patients who could visit our office and receive some designated examinations were included in this study. The re-dislocation rate and patellar apprehension sign postoperatively were evaluated. The Kujala score and Knee Injury and Osteoarthritis Outcome Score (KOOS) were calculated. We assessed the images using plane x-ray and magnetic resonance imaging (MRI). The tilting angle (TA), congruence angle (CA), and lateral shift ratio (LSR) on the plane x-ray were measured pre- and postoperatively and at final follow-up. Using MRI, osteochondral lesions at the patellofemoral joint were evaluated. Results A total of 20 knees of 15 patients (two male, 13 female) who could visit our office were studied. The follow-up rate was 47.6%. The mean age at operation was 19.9 (11–41) years and mean follow-up was 123 (60–215) months. One knee (5.5%) had a history of postoperative subluxation, and five (25%) had a positive apprehension sign. The mean Kujala score significantly improved from 65.5 to 86.1 points (P < 0.05). The mean KOOS (symptom, pain, activities of daily living [ADL], sports, quality of life [QOL]) was 74.4, 92.4, 97.3, 84.1, and 73.2 points, respectively, at final follow-up. On the plane x-ray, patellofemoral alignment was improved postoperatively, and this improvement was maintained at final follow-up. On MRI, in five of 20 cases, the patellofemoral osteoarthritic change was observed at final follow-up. However, in four of these five knees with severe osteochondral lesions, osteochondral fixation or transplantation surgery had been performed. Only one of the remaining 15 knees had a patellofemoral osteoarthritic change observed at final follow-up. Conclusion Middle- to long-term outcome after MPFL reconstruction with Insall’s proximal realignment at our institution was evaluated, and good clinical results were observed. Most patients who did not have a severe cartilage lesion preoperatively did not develop osteoarthritic change.

Abstract
We present a novel optical amplitude regenerator based on blue-chirp spectral slicing using a semiconductor optical amplifier (SOA). The combination of blue-chirp spectral slicing and gain competition in the SOA has a unique input/output (I/O) power-transfer function, which is controlled by the power of an input data signal injected into the SOA. The I/O power-transfer function provides selective amplitude-level regeneration of either the mark or space level of the input data signal. In this paper, we experimentally investigate the transfer function and the regeneration effect using a quantum-dot semiconductor optical amplifier. The results show that the regenerator has unique regeneration effect, specialized for either the mark or space level of a 10-Gbit/s on-off keying signal.

Abstract
BACKGROUND AND AIM This study analyzed inflammatory bowel disease activity for 2 years after the Great East Japan Earthquake. METHODS We compared the relapse rates of patients with ulcerative colitis or Crohn's disease 1 and 2 years after the earthquake with rates immediately after the earthquake. To evaluate continuous disease courses, we also performed multivariate time-to-event analyses from the time of the earthquake to the onset of additional treatments. RESULTS Of 903 patients with ulcerative colitis or Crohn's disease in our previous study, we could evaluate 2-year courses in 677 patients (394 ulcerative colitis and 283 Crohn's disease). Compared with the relapse rates of ulcerative colitis and Crohn's disease immediately after the earthquake (15.8% and 7.0%, respectively), those in the corresponding periods in 2012 (2.5% and 1.1%, respectively) and 2013 (2.3% and 2.5%, respectively) significantly decreased. There were 226 patients who required additional treatments after the earthquake. Multivariate time-to-event analyses revealed that only patients who had experienced the death of family members or friends were likely to need additional treatments (hazard ratio = 1.77, 95% confidence interval = 1.25-2.47). No other factors had a significant influence. CONCLUSIONS The relapse rates 1 and 2 years after the earthquake significantly decreased. The factors that influenced long-term relapse were different from those that influenced short-term relapse.

Abstract
Anchorage of pedicle screw instrumentation in the elderly spine with poor bone quality remains challenging. In this study, micro finite element (µFE) models were used to assess the specific influence of screw design and the relative contribution of local bone density to fixation mechanics. These were created from micro computer tomography (µCT) scans of vertebras implanted with two types of pedicle screws, including a full region-or-interest of 10 mm radius around each screw, as well as submodels for the pedicle and inner trabecular bone of the vertebral body. The local bone volume fraction (BV/TV) calculated from the µCT scans around different regions of the screw (pedicle, inner trabecular region of the vertebral body) were then related to the predicted stiffness in simulated pull-out tests as well as to the experimental pull-out and torsional fixation properties mechanically measured on the corresponding specimens. Results show that predicted stiffness correlated excellently with experimental pull-out strength (R2 > 0.92, p < .043), better than regional BV/TV alone (R2 = 0.79, p = .003). They also show that correlations between fixation properties and BV/TV were increased when accounting only for the pedicle zone (R2 = 0.66-0.94, p ≤ .032), but with weaker correlations for torsional loads (R2 < 0.10). Our analyses highlight the role of local density in the pedicle zone on the fixation stiffness and strength of pedicle screws when pull-out loads are involved, but that local apparent bone density alone may not be sufficient to explain resistance in torsion.

Abstract
The bovine corneal opacity and permeability (BCOP) assay is an alternative to the Draize test in rabbits. Although it can be used to evaluate ocular non-irritants and severe irritants, it is not used for the assessment of mild-irritating substances. In this assay, a chemical with an in vitro irritancy score (IVIS)≤3 is defined as a "non-irritant" while one with an IVIS>55 is defined as a "corrosive" or "severe irritant." We attempted to evaluate mild eye irritants by assessing the recovery of corneal lesions histopathologically. Our results indicated that chemicals with IVIS≤6 may be defined as "non-irritants," because the rapid recovery of lesions limited to the squamous layer was predicted by the histopathology. In cases where lesions extended to the wing and basal cell layers, when some intact basal cells remained, the lesions were also predicted to be reversible. Thus, chemicals which induce lesions in which basal cells remain intact can be considered to be mild irritants.

Abstract
The masticator space is located between the masseteric fascia and the pterygoid muscle fascia. Here we report two cases of masticator space abscesses spreading from infections of mandibular teeth. Case 1 is an 85-year-old lady who were referred to Yokohama City University Hospital with a left-cheek swelling and trismus. An enhanced CT scan revealed an abscess extending from the left infratemporal fossa to the temporal fossa. A purulent discharge was observed from her left lower gingiva. We performed surgical drainage under general anesthesia. After infection control, the affected teeth were extracted. Case 2 is an 82-year-old lady who was administered oral bisphosphonate for osteoporosis. She presented to another hospital with fever, trismus and swelling anterior to the right ear after right lower tooth extraction. Because MRI revealed persistent osteomyelitis of her mandible even after antibiotic treatment, she was referred to us. Enhanced CT showed an abscess in the right infratemporal fossa. After surgical drainage similar to Case 1, antibiotics were administered for approximately 4 months to control the osteomyelitis. It is important to recognize that infections of the mandibular teeth can cause an abscess in the masticator space through the pterygomandibular and infratemporal spaces.

Abstract
BACKGROUND Vonoprazan, a potassium-competitive acid blocker, is expected to improve the healing of endoscopic submucosal dissection (ESD)-induced gastric ulcers compared with proton pump inhibitors (PPIs). AIM To compare the healing status of ESD-induced gastric ulcers and the incidence of post-ESD bleeding between subjects treated with vonoprazan for 5 weeks and those treated with PPIs for 8 weeks. METHODS Patients in the vonoprazan group (n = 75) were prospectively enrolled, whereas patients in the PPI group (n = 150) were selected for a 2:1 matched historical control cohort according to baseline characteristics including gastric ulcer size immediately following ESD, age, sex and status of Helicobacter pylori infection. Two controls per case of vonoprazan-treated group were matched with a margin of 20% in terms of ulcer size and a margin of 5 years in terms of their age. RESULTS Although a higher number of completely healed ulcers was observed in the PPI group (95/150, 63.3%) than that in the vonoprazan group (14/75, 18.7%; P < 0.001), the ulcer size reduction rates, which were 96.0 ± 6.7% in the vonoprazan group and 94.7 ± 11.6% in the PPI group, were not significantly different (P = 0.373). The post-ESD bleeding incidence in the vonoprazan group (1/75, 1.3%) was less than that in the PPI group (15/150, 10.0%; P = 0.01). The factors affecting post-ESD bleeding incidence were the type of acid secretion inhibitor (P = 0.016) and use of an anti-thrombotic agent (P = 0.014). CONCLUSION Vonoprazan significantly reduced post-endoscopic submucosal dissection bleeding compared with PPIs.

Abstract
This study investigated the efficacy of intratympanic steroid (ITS) therapy as a salvage treatment for idiopathic sudden sensorineural hearing loss after failure of intravenous steroid (IVS) therapy. Systemic steroid therapy is the only standard drug therapy. However, ethically, we could not simply compare ITS with IVS. Conventionally, we have treated idiopahic sudden sensorineural hearing loss patients after failure of systemic steroid therapy with the double combined therapy IVS and hyperbaric oxygen (HBO), as the salvage modality. We examined the effect of ITS by adding it to the double combined therapy with IVS and HBO. Retrospectively, we clinically examined the effect of double combined therapy with IVS and HBO (A group) for 31 patients (12 men and 19 women) (median age: 54 years) with sudden hearing loss after failure of systemic steroid therapy between June, 2003 and July, 2010. Prospectively, we also examined clinically the effect of triple combined therapy with IVS and HBO, ITS (B group) for 29 patients (17 men and 12 women) (median age: 51 years) with sudden hearing loss after failure of systemic steroid therapy between August, 2010 and April, 2012. In the examination of patients treated within 30 days from the onset, one patient (3.2%) demonstrated remarkable recovery, 6 patients (19.4%) demonstrated mild recovery, while no change was noted in 24 patients (77.4%) in the A group. In the B group, 5 patients (17.2%) demonstrated complete recovery, 3 patients (10.3%) demonstrated remarkable recovery, mild recovery was seen in 14 patients (48.3%), and the remaining 7 patients (24.1%) showed no change. There was a significant difference (p < 0.05) between the A group and the B group. Furthermore, the hearing improvement in group B in five pure tone average was significantly better than in the group A (p < 0.05). We concluded that the B group demonstrated better hearing improvement than the A group. Therefore, ITS could be effective for idiopathic sudden sensorineural hearing loss patients after failure of systemic steroid therapy.

Abstract
Noble gas molecules have not hitherto been detected in space. From spectra obtained with the Herschel Space Observatory, we report the detection of emission in the 617.5- and 1234.6-gigahertz J = 1-0 and 2-1 rotational lines of (36)ArH(+) at several positions in the Crab Nebula, a supernova remnant known to contain both molecular hydrogen and regions of enhanced ionized argon emission. Argon-36 is believed to have originated from explosive nucleosynthesis in massive stars during core-collapse supernova events. Its detection in the Crab Nebula, the product of such a supernova event, confirms this expectation. The likely excitation mechanism for the observed (36)ArH(+) emission lines is electron collisions in partially ionized regions with electron densities of a few hundred per centimeter cubed.

Abstract
OBJECTIVE Stress is thought to be one of the triggers of relapses in patients with inflammatory bowel disease (IBD). We examined the rate of relapse in IBD patients before and after the Great East Japan Earthquake. DESIGN A retrospective cohort study. SETTINGS 13 hospitals in Japan. PARTICIPANTS 546 ulcerative colitis (UC) and 357 Crohn's disease (CD) patients who received outpatient and inpatient care at 13 hospitals located in the area that were seriously damaged by the earthquake. Data on patient's clinical characteristics, disease activity and deleterious effects of the earthquake were obtained from questionnaires and hospital records. PRIMARY OUTCOME We evaluated the relapse rate (from inactive to active) across two consecutive months before and two consecutive months after the earthquake. In this study, we defined 'active' as conditions with a partial Mayo score=2 or more (UC) or a Harvey-Bradshaw index=6 or more (CD). RESULTS Among the UC patients, disease was active in 167 patients and inactive in 379 patients before the earthquake. After the earthquake, the activity scores increased significantly (p<0.0001). A total of 86 patients relapsed (relapse rate=15.8%). The relapse rate was about twice that of the corresponding period in the previous year. Among the CD patients, 86 patients had active disease and 271 had inactive disease before the earthquake. After the earthquake, the activity indices changed little. A total of 25 patients experienced a relapse (relapse rate=7%). The relapse rate did not differ from that of the corresponding period in the previous year. Multivariate analyses revealed that UC, changes in dietary oral intake and anxiety about family finances were associated with the relapse. CONCLUSIONS Life-event stress induced by the Great East Japan Earthquake was associated with relapse in UC but not CD.

Abstract
The palisade vessels present at the distal end of the esophagus are considered to be a landmark of the esophagogastric junction and indispensable for diagnosis of columnar-lined esophagus on the basis of the Japanese criteria. Here we clarified the features of normal palisade vessels at the esophagogastric junction using magnifying endoscopy. We prospectively studied palisade vessels in 15 patients undergoing upper gastrointestinal endoscopy using a GIF-H260Z instrument (Olympus Medical Systems Co., Tokyo, Japan). All views of the palisade vessels were obtained at the maximum magnification power in the narrow band imaging mode. We divided the area in which palisade vessels were present into three sections: the area from the squamocolumnar junction (SCJ) to about 1 cm orad within the esophagus (Section 1); the area between sections 1 and 3 (Section 2); and the area from the upper limit of the palisade vessels to about 1 cm distal within the esophagus (Section 3). In each section, we analyzed the vessel density, caliber of the palisade vessels, and their branching pattern. The vessel density in Sections 1, 2, and 3 was 9.1 ± 2.1, 8.0 ± 2.6, and 3.3 ± 1.3 per high-power field (mean ± standard deviation [SD]), respectively, and the differences were significant between Sections 1 and 2 (P= 0.0086) and between Sections 2 and 3 (P < 0.0001). The palisade vessel caliber in Sections 1, 2, and 3 was 127.6 ± 52.4 µm, 149.6 ± 58.6 µm, and 199.5 ± 75.1 µm (mean ± SD), respectively, and the differences between Sections 1 and 2, and between Sections 2 and 3, were significant (P < 0.0001). With regard to branching form, the frequency of branching was highest in Section 1, and the 'normal Y' shape was observed more frequently than in Sections 2 and 3. Toward the oral side, the frequency of branching diminished, and the frequency of the 'upside down Y' shape increased. The differences in branching form were significant among the three sections (P < 0.0001). These results indicate that the density of palisade vessels is highest near the SCJ, and that towards their upper limit they gradually become more confluent and show an increase of thickness. Within a limited area near the SCJ, observations of branching form suggest that palisade vessels merge abruptly on the distal side. We have demonstrated that palisade vessels are a useful marker for endoscopic recognition of the lower esophagus.

Abstract
Contralateral pneumothorax is one of severe complications after lung resection. We present our experiences with surgical treatment of 5 cases [case 4 is under the percutaneous cardiopulmonary support (PCPS) assistance] of contralateral pneumothorax after lung resection. All cases were men and not able to stop smoking, the disease caused by lung resection was lung cancer 3 and tuberculosis 2. Operative procedure was lobectomy 4 and pneumonectomy 1. Tracheal intubation was done before radiological confirmation of pneumothorax in 4 cases. Immediately after diagnosis all patients underwent chest drainage. Because the contralateral pneumothorax after lung resection is severe complication, we thought that surgical treatment is necessary. Though the thoracoscopic surgery under the PCPS assistance is also possible, it seems that a small thoracotomy with adjusting ventilation by anesthetist are more favorable. Accurate diagnosis and treatment is the key for success of treatment. The patient who receives lung resection due to lung cancer often has emphysema, and the risk of contralateral pneumothorax after the operation should also be explained.

Abstract
Thoracolithiasis is a rare condition with only 16 cases of surgically removed nodules reported in the literature in Japan. We report an additional thoracoscopically removed case. A 62-year-old man was pointed out an abnormal shadow behind the left diaphragmatic dome on a routine health examination. Computed tomography (CT) revealed a round mass lesion with calcification, about 11 mm in diameter, in the left thorax. Video-assisted thoracic surgery (VATS) was performed and a white 11 mm completely free nodule in the left pleural cavity was removed. Pathological findings revealed necrotic fat tissue in the center surrounded by hyalinized fibrous tissue, being consistent with thoracolithiasis.

Abstract
The detection of circumstellar water vapour around the ageing carbon star IRC +10216 challenged the current understanding of chemistry in old stars, because water was predicted to be almost absent in carbon-rich stars. Several explanations for the water were postulated, including the vaporization of icy bodies (comets or dwarf planets) in orbit around the star, grain surface reactions, and photochemistry in the outer circumstellar envelope. With a single water line detected so far from this one carbon-rich evolved star, it is difficult to discriminate between the different mechanisms proposed. Here we report the detection of dozens of water vapour lines in the far-infrared and sub-millimetre spectrum of IRC +10216 using the Herschel satellite. This includes some high-excitation lines with energies corresponding to approximately 1,000 K, which can be explained only if water is present in the warm inner sooty region of the envelope. A plausible explanation for the warm water appears to be the penetration of ultraviolet photons deep into a clumpy circumstellar envelope. This mechanism also triggers the formation of other molecules, such as ammonia, whose observed abundances are much higher than hitherto predicted.

Abstract
Radical segmentectomy is being performed for small-sized lung cancer. However, it is not always easy to identify the intersegmental border. In this report, we present a new method to recognize it easier by using the nozzle of fibrin sealant spray kit. The diseased segment can be inflated through a pin hole which is placed distal to the ligation at segmental bronchus. In our 20 cases, successful inflation of diseased segment was easily done through thoracoscopic procedure.

Autocrine loop between vascular endothelial growth factor (VEGF)-C and VEGF receptor-3 positively regulates tumor-associated lymphangiogenesis in oral squamoid cancer cells.

Abstract
Numerous past studies have suggested a critical role of the paracrine effect between tumor vascular endothelial growth factor (VEGF)-C and lymphatic FLT-4 in solid tumor-associated lymphangiogenesis. In contrast, the pathophysiological role of tumor cell-associated FLT-4 in tumor progression remains to be elucidated. Here, we investigated this role using a tumor implantation model. SAS cells, an oral squamous carcinoma cell line expressing both VEGF-C and FLT-4 but neither FLK-1/KDR nor VEGF-D were adopted for experiments. Stable transformants of dominant-negative (dn) SAS cells were established in which the cytoplasmic domain-deleted FLT-4 was exogenously overexpressed, which can lead to inactivation of endogenous FLT-4 through competitive antagonism and is associated with down-activation of endogenous FLT-4-related intracellular signals. In vitro and in vivo proliferation assays showed lower proliferative activity of dn-SAS cells. An immunohistochemical study revealed that the tumor lymphangiogenesis was significantly suppressed, and the level of human VEGF-C mRNA was significantly lower in dn-SAS cell-derived tumor tissues. Moreover, in vitro studies demonstrated that the significant suppression of VEGF-C and VEGF-A expression was evident in dn-SAS cells or wild-type SAS cells treated with either the FLT-4 kinase inhibitor MAZ51 or the inhibitor of FLT-4-related signals. These findings together suggested that the VEGF-C/FLT-4 autocrine loop in tumor cells was a potential enhancer system to promote cancer progression, and FLT-4 in tumor tissue might become an effective target for cancer therapy.
