Potential Beneficial Effects of Crab-Flavored Seafood Intake in Young Rats.

Background: Crab-flavored seafood is a well-known traditional Japanese product that is sold as "imitation crab" worldwide. Although it is a low-cost, low-fat, high-protein food, there are few data on its potential health benefits. Here, we have assessed the effects of crab-flavored seafood consumption on organ weight and serum biomarkers levels in rats.

Consumption of fish balls "tsumire" may help prevent liver function deterioration in aged rats.

Possible health benefits of fish balls tsumire consumption on human health have been deduced based on the results of our earlier study investigating tsumire consumption by young (6-weeks-old) Sprague-Dawley rats. The objectives of this study were to evaluate the effect of tsumire intake on aged rats by feeding them a diet containing 5% dried tsumire. Biomarker levels and organ weight of 80-weeks-old Sprague-Dawley rats that were fed with tsumire were examined for potential health benefits.

Effect of fish paste products, fish balls 'tsumire', intake in Sprague-Dawley rats.

The fish paste product, fish balls 'tsumire', is a traditional type of Japanese food made from minced fish as well as imitation crab, kamaboko and hanpen. Although tsumire is known as a high-protein and low-fat food, there is a lack of scientific evidence on its health benefits. Hence, we aimed to investigate the effects of tsumire intake on organ weight and biomarker levels in Sprague-Dawley rats for 84 d as a preliminary study.

Effect of fish paste products "Hanpen" intake in Sprague-Dawley rats.

Fish paste product, "Hanpen," is a traditional type of Japanese food made from minced fish as well as imitation crab and kamaboko, and a marshmallow-like soft texture is characteristic of hanpen. Hanpen is known as a high-protein and low-fat food. However, there is a lack of evidence on its health benefits.

leaf extract suppresses obesity in high-fat diet-induced obese mice.

Background: Obesity is a serious health problem in the world. We thought that the activity and safety of natural plants and/or foods are very important in the management of therapy for obesity. () is also known as lacquer tree in Japan and Korea, and it is consumed as food ingredients and/or traditional herbal medicine.

Antitumour and Apoptotic Effects of a Plant Extract Mixture Containing Rhus verniciflua and Other Herbs in Human Leukaemia Cells.

The apoptotic effects of a novel antitumour agent (Rv-PEM01) prepared from 6 kinds of herbs, including were investigated using flow cytometry and western blot analysis. Rv-PEM01 induced apoptosis but not necrosis in MOLT-3, KG-1, and K562 human leukaemia cell lines. Further, Rv-PEM01-treated cells showed significantly upregulated expression of caspase-3 and 9 and cleaved caspase-3 and 9 compared to the control cells.

The yeast Arf-GAP Glo3p is required for the endocytic recycling of cell surface proteins.

Small GTP-binding proteins of the Ras superfamily play diverse roles in intracellular trafficking. Among them, the Rab, Arf, and Rho families function in successive steps of vesicle transport, in forming vesicles from donor membranes, directing vesicle trafficking toward target membranes and docking vesicles onto target membranes. These proteins act as molecular switches that are controlled by a cycle of GTP binding and hydrolysis regulated by guanine nucleotide exchange factors (GEFs) and GTPase-activating proteins (GAPs).

Cancer is the most common cause of death in Japan. Fundamental and clinical studies on cancer were conducted from the viewpoint of Western medicine so far. However, a sustained complete remission has not been achieved yet.

Improved separation and characterization of lipopolysaccharide related compounds by reverse phase ion pairing-HPLC/electrospray ionization-quadrupole-mass spectrometry (RPIP-HPLC/ESI-Q-MS).

A new approach for the separation and inline characterization of lipopolysaccharide (LPS) related compounds has been developed. The separation was based on the difference in the number of charged phosphate and ethanolamine groups, as non-stoichiometric substituents, on the polysaccharide backbone, and was achieved with reverse phase ion-pairing chromatography (RPIP-HPLC). Tributylamine was used as an ion-pair reagent.

Diversity of non-stoichiometric substitutions on the lipopolysaccharide of E. coli C demonstrated by electrospray ionization single quadrupole mass spectrometry.

The lipopolysaccharide (LPS) of enterobacteria frequently contains various numbers of charged non-stoichiometric substituents such as phosphate (P) and ethanolamine (EtN) groups and a third residue of 3-deoxy-D-manno-2-octulosonic acid (KDO) on the R-core polysaccharide backbone. These substituents can modify the biological activities of LPS including varying the stability of the outer membrane, tolerance to cationic antibiotics, pathogenicity, and sensitivity to enterobacteria bacteriophages. These diverse substituents can be clearly detected in degraded samples of LPS from E.

Separation and characterization of lipopolysaccharide related compounds by HPLC/post-column fluorescence derivatization (HPLC/FLD) and capillary zone electrophoresis/mass spectrometry (CZE/MS).

The O,N-deacylated derivative (deON) and polysaccharide part (PS) from the lipopolysaccharide (LPS) of Escherichia coli C strain were separated by strongly basic anion-exchange chromatography (SAX) based on the differences in the number of charged phosphate and ethanolamine substituents. They were also successfully separated and characterized by capillary zone electrophoresis and subsequent ESI-ion trap-MS (CZE/ESI-IT-MS). The O-deacylated LPS (deO) presented as a broad peak in CZE/ESI-IT-MS.
