Abstract
Genetic mutations in the purine salvage enzyme, hypoxanthine-guanine phosphoribosyltransferase (HPRT), are known to cause Lesch-Nyhan syndrome and Kelley-Seegmiller syndrome. In patients, purine metabolism is different from that of normal persons. We have previously developed a method for simultaneously determining the concentration of purine and pyrimidine nucleosides and nucleotides. This system was applied to determine the concentrations of nucleosides and nucleotides in HPRT-deficient cell lines. The amount of inosine 5'-monophosphate (IMP) was different in Lesch-Nyhan syndrome, Kelley-Seegmiller syndrome, and control cell lines. The difference in the amount of IMP confirmed the mutation of the enzyme.

Abstract
Autophagy is an essential process for both the maintenance and the survival of cells, with homeostatic low levels of autophagy being critical for intracellular organelles and proteins. In insulin resistant adipocytes, various dysfunctional/damaged molecules, organelles, proteins, and end-products accumulate. However, the role of autophagy (in particular, whether autophagy is activated or not) is poorly understood. In this study we found that in adipose tissue of insulin resistant mice and hypertrophic 3T3-L1 adipocytes autophagy was suppressed. Also in hypertrophic adipocytes, autophagy-related gene expression, such as LAMP1, LAMP2, and Atg5 was reduced, whereas gene expression in the inflammatory-related genes, such as MCP-1, IL-6, and IL-1β was increased. To find out whether suppressed autophagy was linked to inflammation we used the autophagy inhibitor, 3-methyladenine, to inhibit autophagy. Our results suggest that such inhibition leads to an increase in inflammatory gene expression and causes endoplasmic reticulum (ER) stress (which can be attenuated by treatment with the ER stress inhibitor, Tauroursodeoxycholic Acid). Conversely, the levels of inflammatory gene expression were reduced by the activation of autophagy or by the inhibition of ER stress. The results indicate that the suppression of autophagy increases inflammatory responses via ER stress, and also defines a novel role of autophagy as an important regulator of adipocyte inflammation in systemic insulin resistance.

Abstract
We report the results of 28 patients with scaphoid nonunion treated with curettage and biconcave cancellous bone grafting from the distal radius using a volar approach and pin fixation. This study consisted of 28 patients (24 males and 4 females). The mean age at surgery was 28 years. The mean interval from injury to surgery was 22 months. The mean follow-up period was 20 months. By Russe classification, there were 6 distal third nonunions, 19 middle third nonunions and 3 proximal third nonunions. We reviewed final function and radiographic appearance. Bony union was achieved in all cases. Pins were removed at a mean of 7 weeks after surgery. Post-activity pain resolved in all cases. Mean wrist extension was 79° and mean flexion 77°. Mean grip strength was 35.8 kgf. The mean postoperative radio-lunate angle was 4.9° (-21–28.8) compared to -5.9° (-37.5–17.5) preoperatively. No complications were encountered. Our procedure is straightforward and not technically demanding. An STT arthrotomy is not necessary and the technique allows for concurrent correction of carpal instability. Bony union was achieved in all cases with no complications.

Abstract
SIRT6 is a histone deacetylase that has been proposed as a potential therapeutic target for metabolic disorders and the prevention of age-associated diseases. Thus, the identification of compounds that modulate SIRT6 activity could be of great therapeutic importance. The aim of this study was to develop a screening method for the identification of novel modulators of SIRT6 from a natural plant extract. We immobilized SIRT6 onto the surface of magnetic beads, and assessed SIRT6 enzymatic activity on synthetic acetylated histone tails (H3K9Ac) by measuring products of the deacetylation process. The SIRT6 coated magnetic beads were then suspended in fenugreek seed extract (Trigonella foenum-graecum) as a bait to identify active ligands that suppress SIRT6 activity. While the entire extract also inhibited SIRT6 activity in a cell-based assay, the inhibitory effect of two flavonoids from this extract, quercetin and vitexin, was only detected in vitro. This is the first report on the use of protein-coated magnetic beads for the identification of an active ligand from a botanical matrix, and it sets the basis for the de novo identification of SIRT6 modulators from complex biological mixtures.

Abstract
Objectives: This study investigated the clinical features of patients with complete resection of thymic carcinoma. Patients and Methods: The clinical records from 11 patients who underwent a complete resection of thymic carcinoma were retrospectively reviewed. Results: Twelve of 22 patients underwent a resection (a complete resection in 11 and an incomplete in 1). Six of the 11 patients with complete had confirmed recurrent tumors. The 5-year survival rate was 45.4%, and the median survival time was 50.6 months. The patients who underwent complete resection showed significantly better prognosis than cases with incomplete resection and inoperable cases ( p = 0.048). Three of the 6 patients had a recurrence within 1 year. Frequent sites of recurrence were the pleura, pericardium, and lung. Conclusions: A complete resection improved the prognosis of thymic carcinoma. Further prospective studies regarding postoperative adjuvant therapy are necessary to prevent local recurrence after a surgical resection for thymic carcinoma.

Abstract
The aim of the present study was to clarify the involvement of protein kinase Cγ (PKCγ) in the facial neuropathic pain following infraorbital nerve injury. We analyzed the change in PKCγ expression in the trigeminal spinal subnucleus caudalis (Vc) and upper cervical spinal cord (C1/C2) following chronic constriction injury of the infraorbital nerve (ION-CCI). We also studied ION-CCI-mediated mechanical nocifensive behavior in rats. The mechanical head-withdrawal threshold significantly decreased 1 to 14 days after ION-CCI compared with that before ION-CCI and in sham rats. The expression of PKCγ was significantly larger in the ipsilateral Vc compared with the contralateral side in ION-CCI rats 3, 7, and 14 days after ION-CCI. Intrathecal (i.t.) administration of the PKCγ inhibitor chelerythrine prevented an increase in the PKCγ expression in the ipsilateral Vc. Moreover, i.t. administration of chelerythrine annulled ION-CCI-mediated reduction in the head-withdrawal threshold. Taken together, these findings suggest that PKCγ expression in the Vc played an important role in the mechanism of orofacial static mechanical allodynia following trigeminal nerve injury.

Abstract
404 Background: Treatment options for metastatic renal cell carcinoma (mRCC) have increased. Complete remission is, however, rarely seen and patients are treated with multiple sequential therapies. We assessed clinical activity of sorafenib rechallenge after progressing on other therapies. Methods: Patients with mRCC who received a second course of sorafenib therapy after failure of prior sorafenib and other agents were retrospectively identified. RECIST-defined objective response rate and progression-free survival (PFS) and toxicity were analyzed. Results: Fourteen patients with mRCC who were retreated with sorafenib were identified and twelve patients were assessable for this study. 92% were male. Median age at first systemic therapy was 63 years. Prior nephrectomy was performed in 92% of patients. 42% of patients had favorable or intermediate risk, 17% poor, and the rest not available per MSKCC criteria. Eighty-three percent of patients were treated with other agents before initial sorafenib therapy, including 75% interferon-alpha (IFN-alpha), 50% interleukin-2 (IL-2), and 17% sunitinib. First sorafenib therapy began a median of 9.0 months after the diagnosis of mRCC and produced a clinical benefit (PR + SD) rate of 75% and a median PFS of 5.0 months. 67% of patients discontinued initial sorafenib for disease progression and 33% for adverse events. Interval between discontinuation of initial sorafenib and rechallenge was a median of 7.6 months. During the intervening period, 50% of patients were treated with sunitinib, 33% with everolimus, 25% with VEGFR1 vaccine, and others. Clinical benefit rate of 67% and a median PFS of 4.3 months were obtained on sorafenib rechallenge. There was no significant difference in outcome to sorafenib rechallenge based on duration between sorafenib treatments or number or type of intervening treatments. No new severe toxicity was observed during rechallenge. Conclusions: Sorafenib rechallenge has potential to achieve clinical benefits, is well-tolerated, and may be considered after multiple sequential therapies in select mRCC patients. No significant financial relationships to disclose.

Abstract
Diffuse alveolar hemorrhage (DAH) is a rare but fatal complication in patients with systemic lupus erythematosus (SLE). We describe a case of a 74-year-old woman who presented with DAH as an initial presentation of SLE. She also had microscopic polyangiitis clinically manifesting as crescentic glomerulonephritis and purpura with positive myeloperoxidase (MPO)-antineutrophil cytoplasmic antibodies (ANCA). The patient transiently improved when treated with plasma exchange and methylprednisolone pulse therapy; however, she died of recurrent pulmonary hemorrhage and concurrent cryptococcal pneumonia. This case indicates that MPO-ANCA is associated with severe organ involvement such as pulmonary hemorrhage and crescentic glomerulonephritis in SLE.

Abstract
A 77-year-old Japanese man was referred to our hospital because of the progression of renal dysfunction. Two months prior to the admission he had been diagnosed with otitis media. Urinalysis showed proteinuria and microscopic hematuria. Blood examination revealed renal dysfunction, hepatitis C virus (HCV)infection and positive myeloperoxidase (MPO)-ANCA. A chest CT revealed small infiltrates in the right middle lobe. The renal biopsy demonstrated crescentic glomerulonephritis with tubulitis. He was diagnosed as having Wegener's granulomatosis according to the American College of Rheumatology classification criteria. Methylprednisolone pulse therapy followed by oral prednisolone improved all of the otitis media, lung infiltrates and renal function. Recently, a high prevalence of ANCA has been reported in patients with HCV. It has also been reported that the prevalence of HCV infection is high in patients with Wegener's granulomatosis. Therefore, our case points to the clinical significance of HCV infection in ANCA-associated systemic vasculitis including Wegener's granulomatosis.

Abstract
OBJECTIVES Various forms of adrenocortical insufficiency can cause musculoskeletal symptoms such as muscle pain, tautness of the limbs, arthralgia, and flexion contractures. However, the findings of neurological investigations are inconclusive and have not been well summarized. METHODS We report the case of a 61-year-old man with isolated adrenocorticotropic hormone deficiency who presented with musculoskeletal symptoms, including flexion contractures. We performed three neurological investigations: nerve conduction studies, electromyography, and muscle biopsy analysis. Further, we reviewed reports of 16 patients with various forms of adrenocortical insufficiency and musculoskeletal symptoms by considering the findings of these three investigations. RESULTS From the literature review, we found that (a) analysis of muscle biopsy is the most sensitive technique, followed by electromyography and then nerve conduction studies; and (b) the longer the duration of the musculoskeletal symptoms, the greater the incidence of abnormal findings with all three techniques. CONCLUSIONS Physicians may prioritize neurological investigations, depending on these findings.

Abstract
Descending necrotizing mediastinitis (DNM) originating from deep cervical infection is a rare and serious clinical condition with a high mortality rate. Clinical feature of 5 patients undergone surgical drainage for DNM, between 2006 and 2009 were assessed. There were 3 male and 2 female patients whose age ranged from 57 to 83 years old (mean 69.8). All 5 patients had no underlying disease except for 1 patient with severe dental caries. The primary infections of these patients were tonsillitis and pharyngitis. The mean duration from onset of symptom to the referral to our hospital was 14 days (ranged 2 to approximately 41). Two patients underwent cervical drainage for upper mediastinum, and 3 patients were required mediastinal drainage by thoracotomy. There was no post-operative death. Early and aggressive surgical drainage of the neck and mediastinum by a multidisciplinary team of surgeons is very important in the treatment of DNM.

Abstract
Mutations in the uromodulin gene cause the autosomal disorders familial juvenile hyperuricemic nephropathy (FJHN) and medullary cystic kidney disease type 2 (MCKD2). However, methods to detect the mutant form of the uromodulin protein have not been developed. In this study, we developed a liquid chromatography-mass spectrometry (LC-MS) method for detection of the mutated uromodulin peptide (C148W). Our method can distinguish the mutant peptide, GWHWE, from wildtype peptide, GWHC*E. Using MS/MS analysis with a selected reaction monitoring (SRM) mode, peptide-specific fragment ions (m/z 714 --> 381, 471, 567, and 679 for GWHWE and m/z 688 --> 381, 445, 541, and 653 for GWHC*E) were detected.

Abstract
Purine is a general term for purine nucleotides, nucleosides, bases, and nucleic acid. The amount of purine nucleotides, nucleosides, and bases in purine-rich cauliflower was determined with the use of LC-MS and HPLC, and the ratio of these molecules were compared with in raw and in heated condition. Total purine content of raw and heated cauliflower was 42.6 and 43.2 mg/100 g, respectively. Nucleotide content was increased from 0.02 to 50.8 micromol/100 g, and nucleoside content was decreased from 12.4 to 7.7 micromol/100 g, by heating.

Abstract
Marine recreational beaches are monitored for fecal contamination by Enterococcus spp. (ENT) counts. Although different ENT species in the environment tend to thrive in and originate from distinct hosts, the current monitoring method does not differentiate among species. Time-consuming isolation-based species identification precludes routine analysis of environmental ENT communities. Therefore, an isolation-independent DNA fingerprinting method was developed to characterize environmental ENT communities using DNA length polymorphism of the spacer region between the groES and groEL genes common to most ENT species. Capillary electrophoresis resulted in distinct peak sizes of PCR products that carried polymorphic groESL spacers (300-335 bp in length) among 8 different ENT species (Enterococcus avium, Enterococcus gallinarum, Enterococcus casseliflavus, Enterococcus mundtii, Enterococcus hirae, Enterococcus faecium, Enterococcus durans, and Enterococcus faecalis). Distortions in true species ratios observed in electropherograms were caused by PCR biases arising in a mixed ENT community DNA template. E. faecalis was overestimated and E. avium and E. faecium were underestimated compared to the original species ratios in the mixed community. The PCR product bias was constant between species, so good approximation of the species ratio in ENT communities is possible. In environmental samples, a high percentage of E. faecalis (96%) together with high total ENT counts were observed in samples collected from a sewer line and from several sites in a storm drain system where sewage leaks were suspected. In contrast, samples with <400 CFU 100 ml-1 ENT were either dominated by E. mundtii or had 4 or more ENT species. The latter ENT community profiles are considered to be signatures of enterococci rarely associated with animals with low or of non-fecal origin.

Abstract
The combined clinical presentation of acute renal failure with pulmonary hemorrhage is known as pulmonary-renal syndrome. We describe a case of an 84-year-old woman who presented with acute renal failure and pulmonary hemorrhage at onset. Renal biopsy and bone marrow aspiration showed cast nephropathy and an abnormal increase in plasma cells, respectively. She was diagnosed with multiple myeloma and successfully treated with plasma exchange and corticosteroids. This case indicates that multiple myeloma should be considered as a cause of pulmonary-renal syndrome.
