The total nitrogen content and pH of gelatin sauce prepared by dissolving the second-step gelatin hydrolysates (15 g), salt (20 g), sugar (5 g), glucose (2.5 g), inosine monophosphate (IMP) (0.5 g), black pepper (0.1 g), caramel powder (0.1 g), ginger powder (0.05 g), garlic powder (0.05 g), vinegar (3 mL), and fructose (3 mL) in water(100 mL) were 1.71% and 5.35, respectively. The results of a sensory evaluation indicated that when preparing blended soy sauce, the optimal blending ratio of gelatin sauce to commercial soy sauce was 20:80 (v/v). Because the total nitrogen content and pH of the blended soy sauce were 1.52% and 5.31, respectively, the blended soy sauce could be sold as a soy sauce. The oxidative property of the blended soy sauce was similar to that of 20 mM ascorbic acid, and its angiotensi...

However, features of RFID systems present potential security and privacy problems. In an effort to resolve these problems, many kinds of security and privacy enhancement technologies have been researched. However, solutions produced to date still have flaws and are not sufficiently effective for real RFID systems such as the EPCglobal network™. Therefore, in this paper, to make RFID systems more secure and efficient, improved technology based on password, is proposed. The proposed technology combines an encryption algorithm with a password-derived key, and can be applied to low-cost RFID systems for enhancing the security and privacy of these systems.

Transplantable KHT sarcoma and a spontaneous adenomammary carcinoma served as tumor models. The FAB mass spectra of iodinated Rh-123 indicated that mono and di-iodo products were formed which, as shown by other in vitro tests, were positively charged, and were heavily taken up by the mitochondria of living cells in culture. In animals, it was observed that, initially the radioactivity was taken up by all major organs from which it cleared rapidly including that from the KHT sarcoma; but not from the spontaneous adenomammary carcinoma. As a result, the spontaneous tumors retained much higher radioactivity than the equal weight of blood (x4.3) or muscle (x9.5), and were unequivocally detectable by external scintigraphy. The mitochondria selectivity and the specificity of the radioiodinated Rh-123 for the tumors of epi...

Data was collected using participatory observations and in-depth interviews, as the informants also become investigators themselves through attending informal meetings, open and group discussions, and overt observations with semi-structured questionnaires. Quantitative analyses were accomplished through the informant consensus factor (ICF), fidelity level, and inter-network analysis (INA).

Among the most formidable challenges of reconstructing tooth-supporting osseous defects in the oral cavity is the regeneration of functional multi-tissue complexes involving bone, ligament, and tooth cementum. Furthermore, periodontal multi-tissue engineering with spatiotemporal orientation of the periodontal ligament (PDL) remains the most challenging obstacle for restoration of physiological loading and homeostasis. We report on the ability of a hybrid computer-designed scaffold--developed utilizing computed tomography--to predictably facilitate the regeneration and integration of dental supporting tissues. Here, we provide the protocol for rapid prototyping, manufacture, surgical implantation, and evaluation of dual-architecture scaffolds for controlling fiber orientation and facilitating morphogenesis of bone-ligament complexes. In contrast to conventional single-system methods of fibrous tissue formation, our protocol supports rigorous control of multi-compartmental scaffold architecture using computational scaffold design and manufacturing by 3D printing, as well as the evaluation of newly regenerated tissue physiology for clinical implementation.

Research paper thumbnail of Identification and characterization of a new conserved motif within the presequence of proteins targeted into complex diatom plastids

Due to this explicit evolutionary history such algae possess plastids that are surrounded by either three or four membranes. Protein targeting into plastids of these organisms depends on N-terminal bipartite presequences consisting of a signal and a transit peptide domain. This suggests that different protein targeting systems may have been combined during establishment of secondary endocytobiosis to enable the transport of proteins into the plastids. Here we demonstrate the presence of an apparently new type of transport into diatom plastids. We analyzed protein targeting into the plastids of diatoms and identified a conserved amino acid sequence motif within plastid preprotein targeting sequences. We expressed several diatom plastid presequence:GFP fusion proteins with or without modifications within that motif in the diatom Phaeodactylum tricornutum and found that a single conserved phenylalanine is crucial for protein transport into the diatom plastids in vivo, thus indicating the presence of a so far unknown new type of targeting signal. We also provide experimental data about the minimal requirements of a diatom plastid targeting presequence and demonstrate that the signal peptides of plastid preproteins and of endoplasmic reticulum-targeted preproteins in diatoms are functionally equivalent. Furthermore we show that treatment of the cells with Brefeldin A arrests protein transport into the diatom plastids suggesting that a vesicular transport step within the plastid membranes may occur.

Reconstruction of the support and function of affected tooth-supporting tissues represents an important therapeutic endpoint for periodontal regenerative medicine. An improved understanding of periodontal biology coupled with current advances in scaffolding matrices has introduced novel treatments that use cell and gene therapy to enhance periodontal tissue reconstruction and its biomechanical integration. Cell and gene delivery technologies have the potential to overcome limitations associated with existing periodontal therapies, and may provide a new direction in sustainable inflammation control and more predictable tissue regeneration of supporting alveolar bone, periodontal ligament, and cementum. This review provides clinicians with the current status of these early-stage and emerging cell- and gene-based therapeutics in periodontal regenerative medicine, and introduces their future application in clinical periodontal treatment. The paper concludes with prospects on the application of cell and gene tissue engineering technologies for reconstructive periodontology.

The aim of our research was to eliminate the redundancy so as to store more rules in TCAM or reduce the area cost. To eliminate the redundancy, we devised Split-TCAM mechanism where a TCAM block is split into every byte. We simulated our Split-TCAM mechanism using Snort v2.8.5 [1]. Results indicated that the proposed mechanism could save the required size of memory to 37.4% and 27.7% on average when applying it to the R-TCAM and Jumping Window algorithm, respectively.
