Abstract
The current study aimed to investigate the effects of ageing on oral immunity using β-defensin (DEFB) 1/2 as a marker and evaluate the effects of curcumin (CUR) on these processes. The study sample included thirty male C57BL/6J mice divided into three groups based on the treatment method used. The young control (YC) and old control (OC) groups received 0·5 % methylcellulose-400 (CUR vehicle) orally for 5 days, whereas the CUR group of older mice received a CUR solution suspended in 0·5 % methylcellulose-400 (dose: 3·0 mg/kg body). DEFB1/2 and immune indicator levels were measured in the saliva and salivary glands post-treatment. The saliva volume and protein content were significantly reduced in the OC group compared with the YC group. CUR administration restored these parameters, decreased DEFB1 expression in the salivary gland and increased DEFB1/2 secretion and DEFB2 expression. These findings were supported by epigenetic gene regulation and partial cytokine activation from changes in WD40 repeat protein 5, TNF alpha and IL-1beta. CUR can partially restore age-related changes in oral immune responses and promote oral health, thereby preventing frailty in the older population through a nutritional therapeutic pathway.

Abstract
PURPOSE Pheochromocytoma crisis is a life-threatening endocrine emergency that requires prompt diagnosis and treatment. Because of its rarity, sudden onset, and lack of internationally uniform and validated diagnostic criteria, pheochromocytoma crisis remains to be fully clarified. Therefore, we aimed to describe the clinical characteristics and outcomes of pheochromocytoma crisis through a literature review. METHODS We performed a systematic literature search of PubMed/MEDLINE database, Igaku-Chuo-Zasshi (Japanese database), and Google Scholar to identify case reports of pheochromocytoma crisis published until February 5, 2021. Information was extracted and analyzed from the literature that reported adequate individual patient data of pheochromocytoma crisis in English or Japanese. Cases were also termed as pheochromocytoma multisystem crisis (PMC) if patients had signs of hyperthermia, multiple organ failure, encephalopathy, and labile blood pressure. RESULTS In the 200 cases of pheochromocytoma crisis identified from 187 articles, the mean patient age was 43.8 ± 15.5 years. The most common symptom was headache (39.5%). The heart was the most commonly damaged organ resulting from a complication of a pheochromocytoma crisis (99.0%), followed by the lungs (44.0%) and the kidney (21.5%). PMC accounted for 19.0% of all pheochromocytoma crisis cases. After excluding 12 cases with unknown survival statuses, the mortality rate was 13.8% (26/188 cases). Multivariable logistic regression analysis revealed that nausea and vomiting were significantly associated with a higher mortality rate. CONCLUSION Pheochromocytoma can present with different symptomatology, affecting different organ systems. Clinicians should be aware that patients with nausea or vomiting are at a higher risk of death because of pheochromocytoma crisis.

Abstract
STUDY DESIGN Retrospective multicenter study. OBJECTIVES To analyze the predictive factors for postoperative ambulatory recovery in paretic non-ambulatory patients with metastatic spinal cord compression (MSCC). SETTING Japan. METHODS Eighty-two consecutive patients (74.4% men; mean age, 66.2 years) who could not walk before surgery due to cervical or thoracic MSCC and underwent posterior decompressive surgery between 2003 and 2014 were included. Patients were divided into two groups according to ambulatory status at 6 weeks after surgery: recovery (group R) and non-recovery (group NR). To evaluate the speed of progression of motor deficits, we assessed the period from onset of neurological symptoms to gait inability (T1). RESULTS Fifty patients (61.0%) regained the ability to walk (group R). The period of T1 demonstrated a positive correlation with probability of ambulatory recovery (P=0.00; Kendall's tau-b=0.38), and a receiver operating characteristic curve analysis showed that the cutoff value of T1 was 5 days (area under the curve=0.72; P=0.001). In multivariate analysis, <6 days of T1 was one of the independent risk factors for failing to regain ambulatory ability (odds ratio, 8.74; P=0.00). CONCLUSIONS The speed of progression of motor deficits can independently and powerfully predict the chance of postoperative ambulatory recovery as well as previously identified predictors. Since information about the speed of progression can be obtained easily by interviewing patients or family members, even if the patient is in an urgent state, our results will be helpful in clinical decision-making.

Abstract
We aimed to realize smooth 3D biped walking in a robot through control based on information obtained from various sensors. We employed a method to control walking by divid ing it into motions in the sagittal plane and in the lateral plane. We treated motion in the lateral plane as a regulator prob lem with two equilibrium states. We also used relatively low gain feedback coefficients obtained from the optimal regula tor theory. For motion in the sagittal plane, we put the body speed close to the smooth speed function given in advance by controlling the ankle torque. The effectiveness of the proposed control method was ex amined by computer simulation and proved by experiments with our BLR-G2 walking robot. The BLR-G2 is equipped with foot pressure and ankle torque sensors to provide infor mation about the condition of contact with the floor. The sole and ankle driving actuators undergo force/torgue feedback control based on the sensor information. These contributed toward realizing smooth walking with the sole firmly gripping the floor.

Abstract
Reproductive success depends on a robust and appropriately timed preovulatory luteinizing hormone (LH) surge, which is induced by the activation of gonadotropin-releasing hormone (GnRH) neurons in response to positive feedback from increasing estrogen levels. Here we document an increase in postsynaptic GluR2-lacking Ca2+ -permeable AMPA-type glutamate receptors (CP-AMPARs) at synapses on GnRH neurons on the day of proestrus in rats, coincident with the increase in estrogen levels. Functional blockade of CP-AMPARs depressed the synaptic responses only on the day of proestrus and concomitantly attenuated the LH surge. Thus, the phasic synaptic incorporation of postsynaptic CP-AMPARs on GnRH neurons is involved in the generation of the LH surge.

Abstract
Like other fields of medicine, robotics and mechanization might be introduced into endovascular coil embolization of intracranial aneurysms for effective treatment. We have already reported that coil insertion force could be smaller and more stable when the coil delivery wire is driven mechanically at a constant speed. Another background is the difficulty in synchronizing operators' minds and hands when two operators control the microcatheter and the coil respectively. We have therefore developed a mechanical coil insertion system enabling a single operator to insert coils at a fixed speed while controlling the microcatheter. Using our new system, the operator manipulated the microcatheter with both hands and drove the coil using foot switches simultaneously. A delivery wire force sensor previously reported was used concurrently, allowing the operator to detect excessive stress on the wire. In vitro coil embolization was performed using three methods: simple mechanical advance of the coil; simple mechanical advance of the coil with microcatheter control; and driving (forward and backward) of the coil using foot switches in addition to microcatheter control. The system worked without any problems, and did not interfere with any procedures. In experimental coil embolization, delivery wire control using the foot switches as well as microcatheter manipulation helped to achieve successful insertion of coils. This system could offer the possibility of developing safer and more efficient coil embolization. Although we aim at total mechanization and automation of procedures in the future, microcatheter manipulation and synchronized delivery wire control are still indispensable using this system.

Abstract
We investigated the non-genomic effects of glucocorticoids (GCs) on inhibition of plasma membrane lipid raft formation in activated human basophils. Human basophils obtained from house dust mite (HDM)-sensitive volunteers were pretreated with hydrocortisone (CORT) or dexamethasone (Dex) for 30 min and then primed with phorbol 12-myristate 13-acetate (PMA, 10 ng/ml) or HDM (10 µg/ml). The expression of CD63, a basophil activation marker, was assessed by flow cytometry. Membrane-bound GC receptors (mGCRs) were analysed by flow cytometry and confocal laser microscopy. Lipid rafts were assessed using a GM1 ganglioside probe and visualization by confocal laser microscopy. Pretreatment of basophils with CORT (10(-4) M and 10(-5) M) and Dex (10(-7) M) significantly inhibited CD63 expression 20 min after addition of PMA or HDM. The inhibitory effects of GCs were not altered by the nuclear GC receptor (GCR) antagonist RU486 (10(-5) M) or the protein synthesis inhibitor cycloheximide (10(-4) M) (P < 0·05). CORT coupled to bovine serum albumin (BSA-CORT) mimicked the rapid inhibitory effects of CORT, suggesting the involvement of mGCRs. mGCRs were detectable on the plasma membrane of resting basophils and formed nanoclusters following treatment with PMA or HDM. Pretreatment of cells with BSA-CORT inhibited the expression of mGCRs and nanoclustering of ganglioside GM1 in lipid rafts. The study provides evidence that non-genomic mechanisms are involved in the rapid inhibitory effect of GCs on the formation of lipid raft nanoclusters, through binding to mGCRs on the plasma membrane of activated basophils.

Abstract
AIM The aim of this study was to clinically evaluate percutaneous endoscopic gastrostomy (PEG) tube feeding of elderly Japanese patients with dementia. METHOD The records of the 155 patients with dementia who underwent PEG in Juntendo Tokyo Koto Geriatric Medical Center were reviewed for pertinent clinical data, including diagnosis of dementia, place of stay before and after hospitalization, as well as survival rate, albumin levels, and incidence of aspiration pneumonia (AP) before and 6 months after PEG feeding. The latter three data of these patients were compared with those of 106 patients with dementia fed through a nasogastric (NG) tube. RESULTS Alzheimer's disease and vascular dementia were predominant. Fifty-three percent of the patients were admitted from their home; the number of discharges to homes decreased to 21.2%. The mean (SD) of the albumin levels was 2.9 (0.4) g/dl before feeding and 2.9 (0.6) g/dl after 6 months. Among the patients with AP before PEG tube feeding, 51.6% had an AP recurrence. Conversely, AP occurred in 9.4% of the patients without AP before feeding. The patient survival rate was higher by 27 months when using PEG tube than when using an NG tube. CONCLUSION PEG tube feeding in patients with dementia leads to preservation of status for a few years. Compared with NG tube feeding, PEG tube feeding did not induce AP due to impairment of intact swallowing function, and was associated with higher survival rate of approximately 2 years. However, PEG tube feeding does not seem to promote home medical care.

Abstract
A 71-year-old man who had undergone chest wall resection and reconstruction with a Dacron mesh silicone prosthesis for chondrosarcoma 23 years previously presented with a chest wall hematoma. Since the hematoma was found to increase in size over time, we performed an operation to achieve hemostasis. Operative findings showed that the prosthesis had separated into three sheets.

Abstract
ABSTRACTElectromigration activation energies (Ea) of Al and Cu interconnections are strongly dependent on the grain boundary morphology, and it is pointed out that Ea of bamboo-like Al interconnection is not less than Ea of small grain Cu interconnections. Small resistance oscillatory changes caused by electromigration, which are classified into three categories; oscillation, downward spikes, and upward spikes, are investigated in detail. It seems most likely that oscillations correspond to annihilation and formation of the one void. It is also pointed out that downward spikes are local, while upward spikes are non-local. Dislocation dynamics such as generation, rapid transport and subsequent annihilation are considered to be origins of spikes.

Abstract
AbstractCu deposition profiles in submicron contact holes are investigated employing the Cu self-sputtering which do not need any inert gas e.g. Ar during sputtering. Excellent bottom coverage in the high aspect ratio contact holes was obtained at a large target-substrate distance in the selfsputtering due to a long mean free path of Cu ions and atoms, although a coverage is poor in Ar sputtering at 6 mTorr. It is also shown that the self-sputtering has low resputtering effect and high self-diffusivity of Cu, while the resputtering predominates in the case of Ar sputtering when DC bias is applied on the substrate. As a consequence, the bottom coverages of the self-sputtered films are much improved than the Ar sputtered ones. The present work strongly suggests that the self-sputtering is promising to fill Cu in sub micron via and contact holes.

Abstract
We report a resected case of thymoma with a solitary pulmonary metastasis. A 63-year-old woman had pointed out a solitary nodule in right lung field on chest X-ray. Computed tomography (CT) scan showed an anterior mediastinal tumor and a solitary lung nodule in the right lower lobe. Extended thymectomy and partial resection of right lung was performed. Pathological diagnosis showed an invasive thymoma (type B3) and a pulmonary metastasis. Post operative radiotherapy was administered and she is doing well 19 months following the resection. Thymoma with a solitary synclonous pulmonary metastasis is rare and is classified into Masaoka stage IVb. Generally, thymoma cases with distant metastasis are not indication for operation. But, if radical resection is possible, operation is recommended for good prognosis.

Abstract
This report describes Exophiala infection in cultured striped jack, Pseudocaranx dentex, in Japan in 2005. One hundred out of 35,000 fish died per day and mortalities continued for 1 month. Diseased fish showed swelling of the abdomen and kidney distension. Numerous septate hyphae, pale brown in colour, were seen in kidney in squash preparations. Histology revealed abundant fungal hyphae and conidia in gill, heart and kidney. Fungal hyphae were accompanied by cell necrosis and influx of inflammatory, mainly mononuclear cells. The fungus isolated from the diseased fish had septate hyphae, pale brown in colour and 1.8-3.0 microm in diameter. Conidiogenous cells were conspicuous annellides, short or cylindrical or fusiform in shape. Conidia were one-celled, ellipsoidal with smooth walls, accumulated in balls at the apices of annellides that tended to slide down, 1.5-2.0 microm in width and 3.0-5.0 microm in length. The fungus was classified into the genus Exophiala based on its morphology and as Exophiala xenobiotica based on the sequences of the ITS 1-5.8S-ITS 2 regions of rDNA. This is the first record of this fungus in a marine fish.

Abstract
We compared the electroencephalographic changes during actual and imaginary movements with four limbs and classified optimally the responses during four-limb imagery. Evoked potentials in imagery exhibited lower and delayed peaks compared to actual-movement responses, but activations in the primary and the supplementary motor area were similar. Source-modeling analysis revealed that the motor and the parietal cortex were activated similarly, but several dipole sources were active in the frontal cortex for imagery. We compared thirteen classification methods and a combination of template matching and time-frequency methods showed the highest average of 70% classification rate for all limbs.

Abstract
The fungus Paracoccidioides brasiliensis is the pathogen of paracoccidioidomycosis (PCM), a systemic mycosis prevalent in Latin America. The loop-mediated isothermal amplification method (LAMP) was used in this study to detect the presence of P. brasiliensis in sputa samples from patients with chronic PCM, suspected PCM, and a negative control. The target P. brasiliensis gp43 gene was amplified in less than 4 hr in 11 of 18 sputa samples tested. The LAMP method had the advantage of speed and simplicity compared with the classic diagnostic methods such as the histopathological test or biological material culture and did not require sophisticated technical apparatus. It would be an important aid in cases where immediate treatment would mean patient survival, especially in immune-suppressed patients.

Abstract
A 6-month-old Japanese Black female calf became gradually emaciated over a 40-day period and was humanely killed. At necropsy, hyperkeratotic nodules were seen to have spread over almost the entire body surface. Scopulariopsis brevicaulis was isolated from the skin and identified morphologically and by gene sequence analysis of the D1/D2 domain of large subunit ribosomal RNA. Numerous periodic acid-Schiff-positive, lemon-shaped conidia were detected histologically in the keratinized layer and the hair follicles. The distribution of the fungal elements in the skin corresponded to that of the hyperkeratotic lesions. This is the first report of a disease caused by S. brevicaulis in animals. Previously reported human infections have not included generalized hyperkeratosis.

Abstract
Mediastinal hemangioma is a rare tumor. We report a case of a 62-year-old woman with a posterior mediastinal hemangioma. She had a history of right breast cancer and a follow-up chest radiography revealed a mass located in the left posterior mediastinum. The size was about 80 mm in diameter. The tumor surrounded the descending thoracic aorta and involved intercostal arteries. Complete excision could be achieved by decompressing the descending aorta with the aid of partial cardiopulmonary bypass and the aortic cross-clamp. Histologically, the tumor was diagnosed as a benign hemangioma. It was reported that hemangioma would reccur after subtotal excision. To employ cardiopulmonary bypass was a very effective approach for the purpose of complete excision in our case.

Abstract
We describe a patient with aggressive lymphoma who contracted an ethmoidal sinus infection due to Exserohilum rostratum after non-myeloablative allogeneic peripheral blood stem cell transplantation. E. rostratum is an extremely rare causative pathogen of invasive fungal infection. Phylogenetic tree analysis of the D1/D2 domains within the LSU rDNA identified the molecular structure of isolates. We believe this is the first description of E. rostratum infection in a patient who underwent hematopoietic stem cell transplantation.

Abstract
Cancer-specific gene promoter methylation has been described in many types of cancers, and various semi-quantified results have shown their usefulness. Here, we show a more sensitive and specific second-generation system for profiling the DNA methylation status. This method is based on bisulfite reaction of DNA and real-time PCR using two TaqMan MGB probes labeled with different fluorescence, followed by clustering analysis. Primers were designed with CpG-less sequences, and TaqMan MGB probes were designed to contain three or four CpG sites and to be shorter than conventional TaqMan probes. We have added new criteria for primer and probe design for further specificity. We confirmed the reliability of this system and applied it to analysis of lung cancers. Using 10 promoters, 90 primary lung cancers were clustered into six groups consisting of cases having similar smoking status and pathological findings. EGFR mutation and p16 promoter DNA methylation were exclusive, as previously reported; however, DNA methylation in other genes was unrelated to EGFR mutation. This system was also useful to distinguish double primary lung cancers from a single cancer with intrapulmonary metastasis. As above, our system has widespread availability in clinical use and biological research.

Abstract
Paracoccidioidomycosis, a systemic mycosis, is rarely diagnosed in its initial phase and can remain latent for up to 40 years. Although PCR is sensitive for the identification of Paracoccidioides brasiliensis (Pb) in different samples, no study using paraffin-embedded human tissue has been published. The size of the amplicon, the fixation method and the time of the storage may affect the reaction. Recently the more sensitive Primer-Extension-Preamplification (PEP)-Nested-PCR has been used for amplification of small samples. Our aims were to detect Pb in paraffin embedded biopsies using (PEP)-Nested-PCR and to correlate the data with histopathological parameters. Analyses were carried out in 107 biopsies from tegument, lymph node, lung and tongue. The fungal DNA was detected in 29.9% of the biopsies by (PEP)-nested-PCR against 5% of Nested-PCR. The positivity correlated with numbers of fungi and fungal viable cells, and there was no correlation with the granuloma pattern.

Abstract
The term "neuroacanthocytosis" is normally used to refer to autosomal recessive chorea-acanthocytosis and X-linked McLeod syndrome, but there are other movement disorders in which erythrocyte acanthocytosis may also be seen, such as Huntington disease-like 2 and pantothenate kinase-associated neurodegeneration. Disorders of serum lipoproteins such as Bassen-Kornzweig disease form a distinct group of neuroacanthocytosis syndromes in which ataxia is observed, but movement disorders are not seen. Genetic testing has enabled us to distinguish between these disorders, even when there are considerable similarities between phenotypes. Improved detection is important for accurate genetic counseling, for monitoring for complications, and, it is hoped, for implementing causal treatments, once these become available. As in other neurodegenerative conditions, animal models are a promising strategy for the development of such therapies.

Abstract
We report 2 cases of pulmonary thromboembolism after lung resection in patients with schizophrenia. The first case is a 67-year-old woman. She underwent right lower lobectomy for primary lung cancer and suddenly felt dyspnea 2 days after the operation. She was diagnosed pulmonary thromboembolism by computed tomography (CT) and lung perfusion scintigram, and recoverd soon. The second case is a 42-year-old man. He underwent partial resection of the right lung for metastatic germ cell tumor. Six days after the operation, he fell into acute respiratory failure and died in spite of resuscitation. The autopsy showed that the cause of death was pulmonary thromboembolism. Because patients with schizophrenia have high-risk of pulmonary thromboembolism, extreme care must be exercised to avoid it.

Abstract
Human beta-defensins (hBDs) are the most abundant antimicrobial peptides in epithelial cells, and function in the host immune system. Respiratory epithelial cells express hBDs to inhibit bacterial proliferation during respiratory tract infections. The aim of this study was to investigate the release of hBDs into the respiratory tract and their benefit as a host defence system in chronic Pseudomonas aeruginosa infections. The levels of four hBD peptides (hBD-1-hBD-4) were measured in the bronchial epithelial lining fluid (ELF) of nine patients with chronic lower respiratory tract infection caused by P. aeruginosa. Eight patients with idiopathic pulmonary fibrosis and eight volunteers free of pulmonary disease were recruited as controls. ELF was obtained by bronchoscopic microsampling and hBD levels were measured by radioimmunoassays. The antimicrobial effects of hBDs were studied individually and in combination using an in-vitro colony count assay for P. aeruginosa. Concentrations of hBD-1 and hBD-3 tended to be higher in patients with chronic lower respiratory tract infection than in the controls. hBD-2 and hBD-4 were detected in ELF from five and four of nine patients, respectively, but the hBD levels in controls were all below the limits of detection. All patients with infection caused by mucoid P. aeruginosa had detectable hBD-2 and hBD-4 levels in ELF. In-vitro colony count assays showed a potential synergism between hBD-2 and hBD-4 in inhibiting bacterial proliferation. The findings indicate that hBDs, especially hBD-2 and hBD-4, are pathophysiologically important in infections caused by mucoid strains of P. aeruginosa.

Abstract
A 5-year-old male Siberian husky bred outdoor in Tokyo had a swollen paw with interdigital granulomatous lesions in the left hindlimb. The dog had no apparent pulmonary or gastrointestinal involvement. Histopathological analysis of the skin lesions demonstrated yeast-like organisms predominantly within macrophages. Sequence analysis of fungal ribosome RNA gene isolated from a paraffin sample revealed a 100% homology with the teleomorph of Histoplasma capsulatum. The present case may support the concept of primary cutaneous canine histoplasmosis as an endemic phenotype recognized in Japan.

Abstract
In this study, Swiss mice were experimentally infected with Paracoccidoides brasiliensis (Pb18) and we investigated the levels of gp43 in urine and plasma, anti-gp43 and IgG-gp43 immune complexes in plasma. These levels were correlated with the histopathological findings. Blood and urine samples were collected from mice at 7, 28, 56 and 84 days after intravenous inoculation of 10(5) yeast cells, and analysed by ELISA. The results showed increased levels of soluble gp43 in the plasma in all periods, and anti-gp43 IgG and immune complexes after day 28. High gp43 levels were detected in the urine, except for day 28, coincident with the presence of compact granulomas in lungs. All the infected mice showed fungal cells in the lungs, with initial granulomatous lesions at day 7, dissemination of lesions to other organs at day 56, and granulomas lacking the surrounding mononuclear cells infiltration, especially at days 56 and 84. Our results suggest that gp43 diffuses passively into the urine, and the determination of gp43 levels in urine samples may be a non-invasive alternative method for diagnosis and follow up of PCM. Further studies are needed to determine if the cellular immune response correlate with decreased urine gp43 levels.

Abstract
AIMS The nutcracker phenomenon (NCP) is the significant compression of the left renal vein (LRV) by the aorta and superior mesenteric artery (SMA), and found in the patients with so-called idiopathic renal bleeding, orthostatic proteinuria and severe orthostatic intolerance. The purpose of this study is to investigate clinical implications among these disorders possibly related to the NCP. MATERIAL AND METHODS We analyzed 93 pediatric patients (56 with idiopathic renal bleeding, 14 with massive orthostatic proteinuria and 23 with severe orthostatic intolerance), and the findings of 64 patients were compared on both digital subtraction angiography (DSA) and ultrasonography (US) to obtain a new US classification of the NCP with seven grades. RESULTS US grades of the NCP were well-correlated with DSA findings (rs = 0.797, p < 0.0001). LRV stenosis was a typical finding in patients with idiopathic renal bleeding. LRV occlusion was observed in 70% for severe orthostatic intolerance, and in contrast in 18% and 14% for idiopathic renal bleeding and massive orthostatic proteinuria, respectively. Collateral veins on color Doppler US as well as a mirror image of the SMA in the aorta on conventional US were found as subsidiary signs of LRV occlusion. Extreme dilatation of the LRV was present in 44% for massive orthostatic proteinuria and in 7% for idiopathic renal bleeding (p < 0.0001). CONCLUSIONS Anew US classification is useful for the diagnosis of the NCP in diverse clinical symptoms.

Abstract
We have shown that urinary urea excretion increased in rats fed a low quality protein. The purpose of present study was to determine whether an addition of dietary limiting amino acids affected urea synthesis in rats fed a low gluten diet. Experiments were done on three groups of rats given diets containing 10% gluten, 10% gluten +0.5% L-lysine or 10% gluten+0.5% L-lysine, 0.2% L-threonine and 0.2% L-methionine for 10 d. The urinary excretion of urea, and the liver concentrations of serine and ornithine decreased with the addition of dietary L-lysine, L-threonine and L-methionine. The fractional and absolute rates of protein synthesis in tissues increased with the treatment of limiting amino acids. The activities of hepatic urea-cycle enzymes was not related to the urea excretion. These results suggest that the addition of limiting amino acids for the low gluten diet controls the protein synthesis in tissues and hepatic ornithine and decline urea synthesis.

Abstract
1. The present study was carried out to determine whether primordial germ cells isolated from embryonic blood can enter the bloodstream and successfully migrate to the germinal ridges of recipient embryos after transfer to stage X blastoderms, and also whether they can differentiate into blood cells, as is suggested in mice. 2. Primordial germ cells were transfected in vitro by lipofection and then transferred to stage X blastoderms. The introduced GFP gene was efficiently expressed in the gonads of 6-d incubated embryos. 3. Freshly collected primordial germ cells were transferred to stage X blastoderms. The fate of the transferred primordial germ cells was traced by detecting the single nucleotide polymorphism in the D-loop region of the mitochondrial DNA in White Leghorn and Barred Plymouth Rock chickens used in this study. The transferred donor primordial germ cell-derived cells were detected in the gonads, but not in the blood cells, of 17-d incubated embryos by PCR. 4. This procedure for primordial germ cell manipulation could provide a novel method of producing germline chimaeric chickens. 5. In conclusion, our findings indicate that primordial germ cells isolated from embryonic blood can migrate to the germinal ridges of recipient embryos after being transferred to stage X blastoderms. Although these transferred primordial germ cells differentiated into germ cells, no differentiation into blood cells was observed.

Abstract
Familial amyloidotic polyneuropathy (FAP) is the common form of hereditary generalized amyloidosis and is characterized by the accumulation of amyloid fibrils in the peripheral nerves and other organs. Liver transplantation has been utilized as a therapy for FAP, because the variant transthyretin (TTR) is predominantly synthesized by the liver, but this therapy is associated with several problems. Thus, we need to develop a new treatment that prevents the production of the variant TTR in the liver. In this study, we used HepG2 cells to show in vitro conversion of the TTR gene by single-stranded oligonucleotides (SSOs), embedded in atelocollagen, designed to promote endogenous repair of genomic DNA. For the in vivo portion of the study, we used liver from transgenic mice whose intrinsic wild-type TTR gene was replaced by the murine TTR Val30Met gene. The level of gene conversion was determined by real-time RCR combined with mutant-allele-specific amplification. Our results indicated that the level of gene conversion was approximately 11 and 9% of the total TTR gene in HepG2 cells and liver from transgenic mice, respectively. Gene therapy via this method may therefore be a promising alternative to liver transplantation for treatment of FAP.
