Comparison of cell viability between mouse-derived ES-D3 cells and Balb/c 3T3 cells using denture-base lining materials.

The study was done to compare cell viability between ES-D3 and Balb/c 3T3 cells, and evaluate the difference in cell viability between these cell lines using denture-base lining materials for prosthetic dentistry. To compare the cytotoxicity, three acrylic and three silicone dental materials were used. The cell viability was examined by MTT and lactate dehydrogenase (LDH) methods.

Cell viability of fine powders in hybrid resins and ceramic materials for CAD/CAM.

Resin blocks and ceramic blocks for CAD/CAM crowns were cut into powders and separated into three particle size groups. Oxidative stress and cell viability were measured in 3T3 and FRSK cells. The results of cytotoxicity tended to be slightly higher for resin than for ceramics.

Development of technique for embryotoxicity of dental biomaterials.

The Embryonic Stem Cell Test (EST) developed in Germany in 1997 is known as a screening test method capable of predicting the presence of unknown chemicals influencing normal human development. Firstly, we investigated the embryotoxicity of 24 types of monomer including dental monomers and dental alloy-component metal elements using this test. Monomers including Bis-GMA contained in base resin of composite resin exhibited weak embryotoxicity, and the toxicity level varied among dental alloy-component metal elements.

[Development of Determination Method of Ipfencarbazone in Agricultural Products, Livestock Products and Seafood by LC-MS/MS].

A method for the determination of ipfencarbazone in agricultural products, livestock products and seafood by LC-MS/MS was developed. Agricultural samples were extracted with acetone. An aliquot of crude extract was partitioned with n-hexane and sat.

Local Controlled Release of Polyphenol Conjugated with Gelatin Facilitates Bone Formation.

Catechins are extensively used in health care treatments. Nevertheless, there is scarce information about the feasibility of local administration with polyphenols for bone regeneration therapy, possibly due to lack of effective delivery systems. Here we demonstrated that the epigallocatechin-3-gallate-conjugated gelatin (EGCG/Gel) prepared by an aqueous chemical synthesis using 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-morpholinium chloride (DMT-MM) gradually disintegrated with time and facilitated bone formation in a critical size defect of a mouse calvaria.

[Formation of trans-1,3-pentadiene in off-flavor food].

The purpose of the present study is to investigate the production of trans-1,3-pentadiene in a sorbic acid-containing food which was the subject of a complaint that it was off-flavor. Penicillium sp. was isolated from the off-flavor food.

Up-regulation of stearoyl-CoA desaturase 1 increases liver MUFA content in obese Zucker but not Goto-Kakizaki rats.

The Goto-Kakizaki (GK) rat is an animal model for spontaneous-onset, non-obese type 2 diabetes. Despite abundant evidence about disorders in metabolism, little information is available about fatty acid metabolism in the liver of GK rats. This study aimed to investigate the characteristics of the fatty acid profile, particularly MUFA, and the mechanism underlying the alterations in fatty acid profiles in the liver of GK rats.

[A case of diffuse alveolar hemorrhage occurring during the course of rheumatoid arthritis].

A 70-year-old woman, who underwent treatment with prednisolone and methotrexate for rheumatoid arthritis, was admitted to our hospital due to rapidly progressive dyspnea. A chest CT scan showed diffuse ground-glass opacities and reticulonodular shadows in both lungs. Intubation was performed due to severe hypoxia.

[Pulmonary Langerhans cell histiocytosis in identical twins].

Case 1 was a 22-year-old younger sister of identical twins who had smoked 10 cigarettes per day for 4 years since she was 18. She was admitted to our hospital due to dyspnea on exertion, dry cough and bilateral diffuse reticulonodular infiltrates on chest computed tomography (CT). Histological findings of transbronchial lung biopsy demonstrated nodular lesions consisting of spindle-shaped mononuclear cells.

A simple, sensitive determination of ganciclovir in infant plasma by high-performance liquid chromatography with fluorescence detection.

This study developed a simple and sensitive method using reversed-phase high-performance liquid chromatography (HPLC) for ganciclovir (GCV) plasma concentrations in cytomegalovirus infectious infants with hearing loss. The method involves a simple protein precipitation procedure that uses no solid-phase or liquid-liquid extraction. The HPLC separation was carried out on a Cadenza CD-C(18) column (3 microm, 4.

[A case of lung adenocarcinoma keeping complete remission by treatment with gefitinib].

A 74-year-old smoking man was admitted because of lung cancer with metastatic brain tumor. Examinations for lung cancer and brain tumor showed adenocarcinoma (clinical stage IV). Four courses of chemotherapy were not effective.

In vitro embryotoxicity testing of metals for dental use by differentiation of embryonic stem cell test.

We examined embryotoxicity using the embryonic stem cell test (EST) protocol. Tests were conducted using standard reagents for the atomic absorption measurement of 11 metal ions, silver, cobalt, chromium, copper, mercury, nickel, palladium, antimony, tin, vanadium, and zinc from among metals comprising dental alloys. In addition, for four metals like silver, cobalt, chromium, and nickel, the tests were also conducted using a test solution extracted from powder in the cell culture medium.

Simultaneous determination of zonisamide, carbamazepine and carbamazepine-10,11-epoxide in infant serum by high-performance liquid chromatography.

This study developed a simple method for the simultaneous determination of zonisamide (ZNS), carbamazepine (CBZ) and its active metabolite, carbamazepine-10,11-epoxide (CBZE) in infant serum using reversed-phase high-performance liquid chromatograph (HPLC). The method involves a single-step protein precipitation procedure that uses no solid-phase or liquid-liquid extraction. The HPLC separation was carried out on a Cadenza CD-C18 column (3 microm, 4.

[Farmer's lung cases of a farmer and his son with high BAL fluid beta-D glucan levels].

A farmer and his son, who treated straw in a cowshed, were admitted to our hospital because of severe dyspnea during summer time. Their chest X-ray films revealed bilateral reticulonodular shadows in the middle to lower lung fields. Bronchoalveolar lavage (BAL) fluid analyses showed a high proportion of lymphocytes and an increased CD4/8 ratio.

Effects of dehydroepiandrosterone on oleic acid accumulation in rat liver.

The purpose of the present study was to determine whether dehydroepiandrosterone (DHEA) affects de novo fatty acid synthesis, oleic acid formation, fatty acid oxidation, and very low density lipoprotein (VLDL) secretion, in relation to the accumulation of lipid containing oleic acid, in rat liver. The rates of hepatic de novo synthesis of both fatty acid and monounsaturated fatty acid, determined by incorporation of 3H from 3H(2)O into fatty acid, were increased markedly when rats were fed a diet containing 0.5% (w/w) DHEA for 14 days.
