A Study on the Methodology for Ergonomics Design of Naval Weapons Systems (2002)

Ergonomic ship design aims to improve the safety and convenience of crew and passenger. Recently, ergonomic design is a key issue in the warship design. In this paper, as a basis of analyzing and evaluating ergonomic design criteria and evaluation methods for warship, existing military design guidelines and navy criteria in the fields of ergonomics were surveyed. Also, the methodology including ergonomic human model was introduced. Finally, it is shown that the ergonomics evaluation of a design at the early stage of warship design can be performed using commercial ergonomics evaluation model such as Delmia's ERGO.<br/>
Tumor-suppressor genes: news about the interferon connection. (1993)

The interferons are a family of secreted, multifunctional proteins which are components of the defenses of vertebrates against viral, bacterial, and parasitic infections and certain tumors. They exert their various activities by inducing the synthesis of a large variety of proteins. There are direct and indirect indications that several of these proteins may have tumor-suppressor activities. The interferon-inducible proteins implicated include: (i) a double-stranded RNA-activatable protein kinase that can phosphorylate and thereby inactivate the eukaryotic peptide chain initiation factor eIF-2; (ii) the interferon regulatory factors IRF-1 and IRF-2, which can modulate the expression of the interferons and of some interferon-inducible proteins; and (iii) RNase L, a latent endoribonuclease which can be activated by (2'-5')oligoadenylates, the products of a family of enzymes which are also interferon-inducible. It is note-worthy that some of the proteins encoded by tumor virus oncogenes (e.g., E1A from adenovirus, EBNA-2 from Epstein-Barr virus, and terminal protein from hepatitis B virus) impair the induction of at least some proteins by interferons.
Amino acid sequence and three‐dimensional structure of the Tn‐specific isolectin B4 from Vicia villosa (1997)

The partial amino acid sequence of the tetrameric isolectin B4 from Vicia villosa seeds has been determined by peptide analysis, and its three-dimensional structure solved by molecular replacement techniques and refined at 2.9 A resolution to a crystallographic R-factor of 21%. Each subunit displays the thirteen-stranded beta-barrel topology characteristic of legume lectins. The amino acid residues involved in metal- and sugar-binding are similar to those of other GalNAc-specific lectins, indicating that residues outside the carbohydrate-binding pocket modulate the affinity for the Tn glycopeptide. Isolectin B4 displays an unusual quaternary structure, probably due to protein glycosylation.
Wind-Induced Fatigue Analysis of High-Rise Steel Structures Using Equivalent Structural Stress Method (2017)

Welded beam-to-column connections of high-rise steel structures are susceptive to fatigue damage under wind loading. However, most fatigue assessments in the field of civil engineering are mainly based on nominal stress or hot spot stress theories, which has the disadvantage of dependence on the meshing styles and massive curves selected. To address this problem, in this paper, the equivalent structural stress method with advantages of mesh-insensitive quality and capability of unifying different stress-life curves (S-N curves) into one is introduced to the wind-induced fatigue assessment of a large-scale complicated high-rise steel structure. The multi-scale finite element model is established and the corresponding wind loading is simulated. Fatigue life assessments using equivalent structural stress method, hot spot stress method and nominal stress method are performed, and the results are verified and comparisons are made. The mesh-insensitive quality is also verified. The results show that the lateral weld toe of the butt weld connecting the beam flange plate and the column is the location where fatigue damage most likely happens. Nominal stress method considers fatigue assessment of welds in a more global way by averaging all the stress on the weld section while in equivalent structural stress method and hot spot method local stress concentration can be taken into account more precisely.

In Situ Mechanical Testing of Nanostructured Bijel Fibers (2016)

Bijels are a class of soft materials with potential for application in diverse areas including healthcare, food, energy, and reaction engineering due to their unique structural, mechanical, and transport properties. To realize their potential, means to fabricate, characterize, and manipulate bijel mechanics are needed. We recently developed a method based on solvent transfer-induced phase separation (STRIPS) that enables continuous fabrication of hierarchically structured bijel fibers from a broad array of constituent fluids and nanoparticles using a microfluidic platform. Here, we introduce an in situ technique to characterize bijel fiber mechanics at initial and final stages of the formation process within a microfluidics device. By manipulation of the hydrodynamic stresses applied to the fiber, the fiber is placed under tension until it breaks into segments. Analysis of the stress field allows fracture strength to be inferred; fracture strengths can be as high as several thousand Pa, depending on nanoparticle content. These findings broaden the potential for the use of STRIPS bijels in applications with different mechanical demands. Moreover, our in situ mechanical characterization method could potentially enable determination of properties of other soft fibrous materials made of hydrogels, capillary suspensions, colloidal gels, or high internal phase emulsions.

Tumor prevention and antitumor immunity with heat shock protein 70 induced by 15-deoxy-delta12,14-prostaglandin J2 in transgenic adenocarcinoma of mouse prostate cells. (2000)

The biological modifier delta12-prostaglandin J2 and related prostaglandins have been reported to have significant growth-inhibitory activity with induction of heat shock proteins (Hsps). Tumor-derived Hsps have been shown previously to elicit specific immunity to tumors from which they are isolated. In this study, 15-deoxy-delta12,14-prostaglandin J2 (15d-PGJ2)-induced Hsp70 was purified from transgenic adenocarcinoma mouse prostate cells (TRAMP-C2). It was then tested for its ability to activate specific CTLs and induce protective immunity against prostate cancer in C57BL/6 mice. Treatment of cells with 8.0 microM 15d-PGJ2 for 24 h caused significant induction of Hsp70 expression. The yield of Hsp70 purified from 15d-PGJ2-treated cells was 4-5-fold higher when compared with untreated TRAMP-C2 cells. Vaccination of mice with Hsps isolated from TRAMP-C2 cells elicited tumor-specific CTLs and prevented the growth of TRAMP-C2 tumors. These results indicate that the induced heat shock proteins may have promising applications for antitumor, T-cell immunotherapy. In particular, these findings have important implications for the development of novel anticancer therapies aimed at promoting an immune response to prostate tumors.
NetCache (2017)

We present NetCache, a new key-value store architecture that leverages the power and flexibility of new-generation programmable switches to handle queries on hot items and balance the load across storage nodes. NetCache provides high aggregate throughput and low latency even under highly-skewed and rapidly-changing workloads. The core of NetCache is a packet-processing pipeline that exploits the capabilities of modern programmable switch ASICs to efficiently detect, index, cache and serve hot key-value items in the switch data plane. Additionally, our solution guarantees cache coherence with minimal overhead. We implement a NetCache prototype on Barefoot Tofino switches and commodity servers and demonstrate that a single switch can process 2+ billion queries per second for 64K items with 16-byte keys and 128-byte values, while only consuming a small portion of its hardware resources. To the best of our knowledge, this is the first time that a sophisticated application-level functionality, such as in-network caching, has been shown to run at line rate on programmable switches. Furthermore, we show that NetCache improves the throughput by 3-10x and reduces the latency of up to 40% of queries by 50%, for high-performance, in-memory key-value stores.
Field-to-frame transcoding with spatial and temporal downsampling (2003)

We present an algorithm for transcoding high-rate compressed bitstreams containing field-coded interlaced video to lower-rate compressed bitstreams containing frame-coded progressive video. We focus on MPEG-2 to H.263 transcoding, however these results can be extended to other lower-rate video compression standards including MPEG-4 simple profile and MPEG-1. A conventional approach to the transcoding problem involves decoding the input bitstream, spatially and temporally downsampling the decoded frames, and re-encoding the result. The proposed transcoder achieves improved performance by exploiting the details of the MPEG-2 and H.263 compression standards when performing interlaced to progressive (or field to frame) conversion with spatial downsampling and frame-rate reduction. The transcoder reduces the MPEG-2 decoding requirements by temporally downsampling the data at the bitstream level and reduces the H.263 encoding requirements by largely bypassing H.263 motion estimation by reusing the motion vectors and coding modes given in the input bitstream. In software implementations, the proposed approach achieved a 5/spl times/ speedup over the conventional approach with only a 0.3 and 0.5 dB loss in PSNR for the Carousel and Bus sequences.
Regulatory T cells – a brief history and perspective (2007)

It is now widely accepted that the normal immune system harbors a regulatory T-cell population specialized for immune suppression. It was found initially that some CD4(+) T cells in normal animals were capable of suppressing autoimmunity. Characterization of this autoimmune-suppressive CD4(+) T cell population revealed that they constitutively expressed the CD25 molecule, which made it possible to distinguish them from other T cells, delineate their developmental pathways, in particular their thymic development, and characterize their potent in vivo and in vitro immunosuppressive activity. The marker also helped to identify human regulatory T cells with similar functional and phenotypic characteristics. Recent studies have shown that CD25(+)CD4(+) regulatory T cells specifically express the transcription factor Foxp3. Genetic anomaly of Foxp3 causes autoimmune and inflammatory disease in rodents and humans through affecting the development and function of CD25(+)CD4(+) regulatory T cells. These findings at the cellular and molecular levels altogether provide firm evidence for Foxp3(+)CD25(+)CD4(+) regulatory T cells as an indispensable cellular constituent of the normal immune system and for their crucial roles in establishing and maintaining immunologic self-tolerance and immune homeostasis. They can be exploited for clinical use to treat immunological diseases and control physiological and pathological immune responses.
Distinct DNA-damage-dependent and -independent responses drive the loss of oocytes in recombination-defective mouse mutants (2005)

Defects in meiotic recombination in many organisms result in arrest because of activation of a meiotic checkpoint(s). The proximal defect that triggers this checkpoint in mammalian germ cells is not understood, but it has been suggested to involve either the presence of DNA damage in the form of unrepaired recombination intermediates or defects in homologous chromosome pairing and synapsis independent of DNA damage per se. To distinguish between these possibilities in the female germ line, we compared mouse oocyte development in a mutant that fails to form the double-strand breaks (DSBs) that initiate meiotic recombination (Spo11-/-) to mutants with defects in processing DSBs when they are formed (Dmc1-/- and Msh5-/-), and we examined the epistasis relationships between these mutations. Absence of DSB formation caused a partial defect in follicle formation, whereas defects in DSB repair caused earlier and more severe meiotic arrest, which could be suppressed by eliminating DSB formation. Therefore, our analysis reveals that there are both DNA-damage-dependent and -independent responses to recombination errors in mammalian oocytes. By using these findings as a paradigm, we also examined oocyte loss in mutants lacking the DNA-damage checkpoint kinase ATM. The absence of ATM caused defects in folliculogenesis that were similar to those in Dmc1 mutants and that could be suppressed by Spo11 mutation, implying that oocyte death in Atm-deficient animals is a response to defective DSB repair.
Commitment of Common T/Natural Killer (Nk) Progenitors to Unipotent T and Nk Progenitors in the Murine Fetal Thymus Revealed by a Single Progenitor Assay (1999)

We have established a new clonal assay system that can evenly support the development of T and natural killer (NK) cells. With this system, we show that all T cell progenitors in the earliest CD44(+)CD25(-)FcgammaRII/III(-) fetal thymus (FT) cell population retain NK potential, and that the NK lineage-committed progenitors (p-NK) also exist in this population. T cell lineage-committed progenitors (p-T), which are unable to generate NK cells, first appear at the CD44(+)CD25(-) FcgammaRII/III(+) stage in day 12 FT. The proportion of p-T markedly increases during the transition from the CD44(+)CD25(-) stage to the CD44(+)CD25(+) stage in day 14 FT. On the other hand, p-NK preferentially increase in number at the CD44(+)CD25(-) stage between days 12 and 14 of gestation. The production of p-NK continues up to the CD44(+)CD25(+) stage, but ceases before the rearrangement of T cell receptor beta chain genes. It was further shown that the CD44(+)CD25(-) CD122(+) population of day 14 FT exclusively contains p-NK. These results indicate that the earliest T cell progenitor migrating into the FT is T/NK bipotent, and strongly suggest that the bipotent progenitor continuously produces p-NK and p-T until the CD44(+)CD25(+) stage.
On being 40: a celebration of ‘Should Trees Have Standing?’ (2012)

Few law review
Inhibition of Bacterial Growth by β-Chloro-D-Alanine (1974)

The D- and L-isomers of beta-chloroalanine inhibit the growth of Diplococcus pneumoniae, Streptococcus pyogenes, Bacillus subtilis, and Escherichia coli. With pneumococcus the inhibition by beta-chloro-D-alanine is completely prevented by either D-alanine or D-alanyl-D-alanine, while L-alanine is not effective in preventing the inhibition. The inhibition of growth by beta-chloro-L-alanine is not affected by D-alanine and is only partially prevented by high concentrations of L-alanine. The intracellular free alanine in untreated E. coli and B. subtilis is about 95% in the D-configuration while the free intracellular alanine in both organisms after treatment with beta-chloro-D-alanine is predominantly the L-isomer. These results suggested that the beta-chloroamino acid inactivates alanine racemase (EC 5.1.1.1). Indeed, when extracts of E. coli or B. subtilis were treated with beta-chloro-D-alanine, the activities of alanine racemase and of D-glutamate-D-alanine transaminase were found to be 90-95% inhibited. Studies with mice have shown that beta-chloro-D-alanine is an effective antibacterial agent in vivo againt D. pneumoniae, S. pyogenes, and E. coli.
Colocalization of synaptophysin with transferrin receptors: implications for synaptic vesicle biogenesis. (1991)

We have reported previously that the synaptic vesicle (SV) protein synaptophysin, when expressed in fibroblastic CHO cells, accumulates in a population of recycling microvesicles. Based on preliminary immunofluorescence observations, we had suggested that synaptophysin is targeted to the preexisting population of microvesicles that recycle transferrin (Johnston, P. A., P. L. Cameron, H. Stukenbrok, R. Jahn, P. De Camilli, and T. C. Südhof. 1989. EMBO (Eur. Mol. Biol. Organ.) J. 8:2863-2872). In contrast to our results, another group reported that expression of synaptophysin in cells which normally do not express SV proteins results in the generation of a novel population of microvesicles (Leube, R. E., B. Wiedenmann, and W. W. Franke. 1989. Cell. 59:433-446). We report here a series of morphological and biochemical studies conclusively demonstrating that synaptophysin and transferrin receptors are indeed colocalized on the same vesicles in transfected CHO cells. These observations prompted us to investigate whether an overlap between the distribution of the two proteins also occurs in endocrine cell lines that endogenously express synaptophysin and other SV proteins. We have found that endocrine cell lines contain two pools of membranes positive for synaptophysin and other SV proteins. One of the two pools also contains transferrin receptors and migrates faster during velocity centrifugation. The other pool is devoid of transferrin receptors and corresponds to vesicles with the same sedimentation characteristics as SVs. These findings suggest that in transfected CHO cells and in endocrine cell lines, synaptophysin follows the same endocytic pathway as transferrin receptors but that in endocrine cells, at some point along this pathway, synaptophysin is sorted away from the recycling receptors into a specialized vesicle population. Finally, using immunofluorescent analyses, we found an overlap between the distribution of synaptophysin and transferrin receptors in the dendrites of hippocampal neurons in primary cultures before synapse formation. Axons were enriched in synaptophysin immunoreactivity but did not contain detectable levels of transferrin receptor immunoreactivity. These results suggest that SVs may have evolved from, as well as coexist with, a constitutively recycling vesicular organelle found in all cells.
Phosphatidylinositol 3-Kinase Hyperactivation Results in Lapatinib Resistance that Is Reversed by the mTOR/Phosphatidylinositol 3-Kinase Inhibitor NVP-BEZ235 (2008)

Small molecule inhibitors of HER2 are clinically active in women with advanced HER2-positive breast cancer who have progressed on trastuzumab treatment. However, the effectiveness of this class of agents is limited by either primary resistance or acquired resistance. Using an unbiased genetic approach, we performed a genome wide loss-of-function short hairpin RNA screen to identify novel modulators of resistance to lapatinib, a recently approved anti-HER2 tyrosine kinase inhibitor. Here, we have identified the tumor suppressor PTEN as a modulator of lapatinib sensitivity in vitro and in vivo. In addition, we show that two dominant activating mutations in PIK3CA (E545K and H1047R), which are prevalent in breast cancer, also confer resistance to lapatinib. Furthermore, we show that phosphatidylinositol 3-kinase (PI3K)-induced lapatinib resistance can be abrogated through the use of NVP-BEZ235, a dual inhibitor of PI3K/mTOR. Our data show that deregulation of the PI3K pathway, either through loss-of-function mutations in PTEN or dominant activating mutations in PIK3CA, leads to lapatinib resistance, which can be effectively reversed by NVP-BEZ235.
Effect of Desmopressin Acetate on Bleeding Times and Plasma von Willebrand Factor in Doberman Pinscher Dogs with von Willebrand's Disease (1989)

Effects of desmopressin acetate (1-desamino-8-D-arginine vasopressin [DDAVP]) on plasma von Willebrand factor (vWf) were studied in 12 purebred Doberman pinschers confirmed to have von Willebrand's disease (vWd) (plasma vWf antigen [vWf:Ag] concentrations, less than 30 U/dl). Twelve dogs had subnormal plasma botrocetin cofactor (BCf) activity and 11 dogs had prolonged buccal mucosa bleeding times. Tranquilization of three dogs with lenperone and three dogs with xylazine did not induce significant changes in mean plasma vWf:Ag concentrations or mean BCf activities. Thirty and 120 minutes after administration of DDAVP (1 micrograms/kg subcutaneously), there was significant shortening of the mean buccal mucosa bleeding time. Ten dogs responded to DDAVP with increases in BCf activity which exceeded 10 U/dl at 30 or 120 minutes, or both, after the drug was administered. At the same time, increases in plasma vWf:Ag concentrations were smaller than the increases in BCf activity. It was shown by multimeric analysis that primarily the higher molecular weight forms of vWf increased in plasma in response to DDAVP.
A follow-up of tetracycline-treated rosacea. (1975)

Seventy patients with rosacea were treated with systemic tetracycline for 6 months. Sixty-eight of them cleared with treatment. After withdrawal of the drug seventeen relapsed immediately and the overall relapse rate over 4 years was 69%. The serum tetracycline levels were not significantly different in two patients who failed to respond. Six patients had rosacea keratitis and responded dramatically within I month. Symptoms recurred as the drug was withdrawn. It is suggested that rosacea patients with keratitis should receive early and prolonged tetracycline medication.
