Current bonding systems for resin-bonded restorations and fixed partial dentures made of silver–palladium–copper–gold alloy

SummaryThis review article describes about the bonding systems for noble metal alloys, bonding techniques of restorations and fixed partial dentures (FPDs) made of Ag–Pd–Cu–Au alloys, and their clinical performance. Thione monomers, 6-(4-vinylbenzyl-n-propyl) amino-1,3,5-triazine-2,4-dithione (VTD), 6-methacryloyloxyhexyl-2-thiouracil-5-carboxylate (MTU-6), and 10-methacryloxydecyl 6,8-dithiooctanoate (MDDT), has been proved effective for bonding noble metal alloys. An acrylic adhesive consists of the tri-n-butylborane (TBB) initiator, methyl methacrylate (MMA) monomer liquid with 5% 4-methacryloyloxyethyl trimellitate anhydride (4-META), and poly(methyl methacrylate) (PMMA), is being used for bonding metallic restorations to abutment surfaces. Clinical performance of restorations and FPDs made of Ag–Pd–Cu–Au alloys is overall excellent when they are seated with the currently available noble metal bonding systems

A Case of Pleuroperitoneal Communication in Continuous Ambulatory Peritoneal Dialysis

We present a patient who developed a massive right-Sided hydrothorax two months after starting CAPD treatment, a 41-year-old female with IgA nephropathy who was followed up at our outpatient clinic. Due to deteriorating renal function, a peritoneal catheter was inserted on March 29, 1997．CAPD was implemented on the same day. At the time when CAPD was initiated, the patient was experienclng repeated episodes of nausea and vomiting, probably due to uremia. On May 27, she developed dyspnea. A chest X-ray Showed massive right-Sided hydrothorax. After extracorporeal ultrafiltration was performed, the patient's respiratory distress was rapidly relieved. Two days later, CAPD was esumed, but this resulted in almost immediate recurrence of massive right-sided hydrothorax. The property of the drained fluid from the right pleural cavity and scintigraphy uslng Technetium-99m macroaggregated albumin confirmed pleuroperitoneal communication. Increased intra-abdominal pressure due to frequent vomiting may be responsible for hydrothorax due to pleuroperitoneal communication

Molecular characterization of the CRa gene conferring clubroot resistance in Brassica rapa

Clubroot disease is one of the major diseases affecting Brassicaceae crops, and a number of these crops grown commercially, such as Chinese cabbage (Brassica rapa L. ssp. pekinensis), are known to be highly susceptible to clubroot disease. To provide protection from this disease, plant breeders have introduced genes for resistance to clubroot from the European turnip into susceptible lines. The CRa gene confers specific resistance to the clubroot pathogen Plasmodiophora brassicae isolate M85. Fine mapping of the CRa locus using synteny to the Arabidopsis thaliana genome and partial genome sequences of B. rapa revealed a candidate gene encoding a TIR-NBS-LRR protein. Several structural differences in this candidate gene were found between susceptible and resistant lines, and CRa expression was observed only in the resistant line. Four mutant lines lacking clubroot resistance were obtained by the UV irradiation of pollen from a resistant line, and all of these mutant lines carried independent mutations in the candidate TIR-NBS-LRR gene. This genetic and molecular evidence strongly suggests that the identified gene is CRa. This is the first report on the molecular characterization of a clubroot Resistance gene in Brassicaceae and of the disease resistance gene in B. rapa.ArticlePLANT MOLECULAR BIOLOGY. 80(6):621-629 (2012)journal articl

慢性膵炎患者の全消化管通過に関する研究

Abnormalities of whole gut transit could contribute to the maldigestion and　digestive symptoms of chronic pancreatitis patients. Whole gut transit was measured by radiopaque markers method. Fifteen chronic pancreatitis patients (2 females, 13 males; age range 40-78 years) and 17 controls (4 females, 13 males, 32-73 years) were studied. Additionally, we also looked for evidence of autonomic neuropathy in the chronic pancreatitis patients by using cardiovascular tests. In chronic pancreatitis, whole gut transit was shorter than controls. These abnormalities were not influenced by the degree of autonomic neuropathy. We conclude that whole gut transit is shorter in chronic pancreatitis patients.慢性膵炎の患者の自覚症状や消化不良には消化管の通過異常が関与している可能性がある｡慢性膵炎患者15例と対象群17例で全消化管通過を測定した｡さらに慢性膵炎患者は自律神経機能について評価した｡全消化管通過は慢性膵炎患者は対象群より早いことが示された｡しかしその機序として推定された自律神経機能異常の有無では全消化管通過に差は認められず,慢性膵炎の消化管機能異常の原因は自律神経異常ではないと推定された
