Interferon-gamma, interleukin-4 and interleukin-10 production by T helper cells reveals intact Th1 and regulatory T<sub>R</sub>1 cell activation and a delay of the Th2 cell response in equine neonates and foals (2010)

Cytokines produced by T helper (Th) cells are important in orchestrating the immune response during health and disease. Recent reports indicated that cytokine mRNA expression in foals is often quantitatively lower than that of adult horses suggesting that foal T cells are not fully mature. Here, peripheral blood mononuclear cells from foals and adult horses were stimulated with phorbol 12-myristate 13-acetate and analyzed for intracellular interferon-gamma (IFN-gamma), interleukin-4 (IL-4) and IL-10 production, representing the Th1, Th2 and regulatory TR1 cell phenotypes respectively, by flow cytometry. In agreement with previous reports, all three cytokines were quantitatively reduced in foals compared to adults. However, the balance between Th1 and Th2 cytokines (IFN-gamma/IL-4 ratio) showed a clear Th1-biased response in foals by 6 and 12 weeks of life, while similar IFN-gamma/IL-10 ratios were found in foals and adult horses. By day 5 after birth, intracellular IFN-gamma production by foal CD4+ and CD8+ T cells resembled that in adults. Overall, IL-4 production was low in foals. IL-4+ cells peaked at day 5 of age when IL-4 was mainly produced by IgE+ cells. Relative percentages of IL-4+ Th2 cells were significantly lower in foals at all time points. The data suggested that equine neonates and young foals have an impaired Th2 response, that the immune response of foals is Th1 biased, that IFN-gamma production by Th and cytotoxic T cells is qualitatively similar to adult horses, and regulatory IL-10 production by T cells is developmentally mature in foals during the first three months of life.
Determination of heparin–platelet factor 4–IgG antibodies improves diagnosis of heparin‐induced thrombocytopenia (2001)

Only a few patients with heparin-induced antibodies develop heparin-induced thrombocytopenia (HIT). In this study, we investigated whether different immunglobulin classes can be used to differentiate between antibody-positive patients with and without HIT. Four different patient populations were investigated: 32 patients with the immune type of HIT with thromboembolic complications, 13 patients with HIT without thromboembolism, 24 patients with heparin-platelet factor 4 (PF4) antibodies without clinical symptoms of HIT, and 20 heparin-treated patients with thrombocytopenia caused by other reasons. In all patients the immunglobulin mixture of IgG, IgM and IgA, and the single immunglobulin classes of heparin-PF4 antibodies, were investigated. No significant differences between HIT patients with thromboembolic complications and patients with isolated HIT were found concerning the different immunglobulin classes. Antibody-positive patients with HIT had significantly higher levels of IgG antibodies than those without HIT (P < 0.05), while they did not differ concerning IgM and IgA antibodies. By determining IgG antibodies, the specificity of the enzyme-linked immunosorbent assay (ELISA) system was increased without loss of sensitivity. Heparin-PF4-IgG antibodies can identify patients at risk of developing life-threatening HIT. Future ELISAs should only include this immunglobulin class, as the determination of the antibody mixture may lead to overestimation of HIT.
Environmental Impacts of Metal Ore Mining and Processing: A Review (1997)

Abstract The impact of mining and smelting of metal ores on environmental quality is described. Mines produce large amounts of waste because the ore is only a small fraction of the total volume of the mined material. In the metal industry, production of Cu, Pb, and Zn causes the greatest degradation of the environment. Copper mining produces extensive mine wastes and tailings and Cu smelting emits approximately 0.11 Mg of S per Mg of Cu produced in the USA. Zinc and Pb smelters release large quantities of Cd and Pb into the environment. Metal smelting and refining produce gaseous (CO 2 , SO 2 , NO x , etc.) and particulate matter emissions, sewage waters , and solid wastes . Soil contamination with trace metals is considered a serious problem related to smelting; however, mining and smelting are not main sources of global metal input into soils. Other sources like discarded manufactured products, coal ash, agriculture, and transportation take a lead. Smelters are the main sources of atmospheric emissions of As, Cu, Cd, Sb, and Zn on a global scale and they contribute substantially to the overall emissions of Cr, Pb, Se, and Ni. A quantitative evaluation of the environmental health effects of mining and smelting is difficult because of the complexity of factors involved and lack of consistent methodology. Nevertheless, the case studies described indicate that negative health effects could arise from Pb mining and smelting. Risk assessment revealed that food chain contamination by Cd from soils contaminated by smelting is very unlikely under the western diet.
Zinc induces specific association of PKC with membrane cytoskeleton. (1990)

Putative binding sites for zinc are present in the regulatory domain of protein kinase C but a distinct role for zinc has not yet been proposed. Here we show that micromolar concentrations of zinc chloride cause pure rat brain protein kinase C to localize in a detergent-insoluble, cytoskeletal fraction of red cell membranes and to bind to isolated cytoskeleton in the presence of phosphatidylserine. Attachment of protein kinase C to cytoskeleton was accompanied by enhanced expression of binding sites for 3H-phorbol ester, a regulatory ligand of protein kinase C. The active factor in the cytoskeleton was labile to protease suggesting that protein kinase C binds to a cytoskeletal protein.
Novel CAR T therapy is a ray of hope in the treatment of seriously ill AML patients (2021)

Abstract Acute myeloid leukemia (AML) is a serious, life-threatening, and hardly curable hematological malignancy that affects the myeloid cell progenies and challenges patients of all ages but mostly occurs in adults. Although several therapies are available including chemotherapy, allogeneic hematopoietic stem cell transplantation (alloHSCT), and receptor-antagonist drugs, the 5-year survival of patients is quietly disappointing, less than 30%. alloHSCT is the major curative approach for AML with promising results but the treatment has severe adverse effects such as graft-versus-host disease (GVHD). Therefore, as an alternative, more efficient and less harmful immunotherapy-based approaches such as the adoptive transferring T cell therapy are in development for the treatment of AML. As such, chimeric antigen receptor (CAR) T cells are engineered T cells which have been developed in recent years as a breakthrough in cancer therapy. Interestingly, CAR T cells are effective against both solid tumors and hematological cancers such as AML. Gradually, CAR T cell therapy found its way into cancer therapy and was widely used for the treatment of hematologic malignancies with successful results particularly with somewhat better results in hematological cancer in comparison to solid tumors. The AML is generally fatal, therapy-resistant, and sometimes refractory disease with a disappointing low survival rate and weak prognosis. The 5-year survival rate for AML is only about 30%. However, the survival rate seems to be age-dependent. Novel CAR T cell therapy is a light at the end of the tunnel. The CD19 is an important target antigen in AML and lymphoma and the CAR T cells are engineered to target the CD19. In addition, a lot of research goes on the discovery of novel target antigens with therapeutic efficacy and utilizable for generating CAR T cells against various types of cancers. In recent years, many pieces of research on screening and identification of novel AML antigen targets with the goal of generation of effective anti-cancer CAR T cells have led to new therapies with strong cytotoxicity against cancerous cells and impressive clinical outcomes. Also, more recently, an improved version of CAR T cells which were called modified or smartly reprogrammed CAR T cells has been designed with less unwelcome effects, less toxicity against normal cells, more safety, more specificity, longer persistence, and proliferation capability. The purpose of this review is to discuss and explain the most recent advances in CAR T cell-based therapies targeting AML antigens and review the results of preclinical and clinical trials. Moreover, we will criticize the clinical challenges, side effects, and the different strategies for CAR T cell therapy.
[Effect of human interferon-beta on reconstruction of the choriocapillaris in monkeys following laser photocoagulation]. (1995)

We studied the effect of human interferon-beta on reconstruction of the choriocapillaris following laser photocoagulation in monkey eyes. Moderate dye laser photocoagulation caused the occlusion of the choriocapillaris by the intraluminal thrombus in the photocoagulated lesions on the retina. After 3 days, immature endothelial cells began to migrate towards the center from the edge of the lesions. After 7 days capillaries were newly formed, and after 14 days the choriocapillaris in the lesions was almost reconstructed. Systemic administration of interferon-beta after photocoagulation suppressed the reconstruction of the choriocapillaris remarkably. These results suggest that interferon-beta inhibits proliferation and migration of the capillary endothelium on the retina. Interferon-beta may be effective as medication for the treatment of age-related macular degeneration.
Semantic overlay network for grid resource discovery (2005)

This paper presents a new approach to grid-resource discovery by using semantic peer-to-peer (P2P) overlays. The framework is based on the RDF metadata infrastructure, allowing a rich and extensible description of resources and queries. To avoid flooding the network with a query, we propose a comprehensive semantics-based query forwarding strategy, which only forwards queries to semantically related nodes. After the related nodes have been located, the original RDF query is used to do the final query and retrieval. Results from simulation experiments demonstrate that this architecture is scalable and efficient.
Focus on: Alcohol and the immune system. (2010)

Alcohol abuse suppresses multiple arms of the immune response, leading to an increased risk of infections. The course and resolution of both bacterial and viral infections is severely impaired in alcohol-abusing patients, resulting in greater patient morbidity and mortality. Multiple mechanisms have been identified underlying the immunosuppressive effects of alcohol. These mechanisms involve structural host defense mechanisms in the gastrointestinal and respiratory tract as well as all of the principal components of the innate and adaptive immune systems, which are compromised both through alcohol's direct effects and through alcohol-related dysregulation of other components. Analyses of alcohol's diverse effects on various components of the immune system provide insight into the factors that lead to a greater risk of infection in the alcohol-abusing population. Some of these mechanisms are directly related to the pathology found in people with infections such as HIV/AIDS, tuberculosis, hepatitis, and pneumonia who continue to use and abuse alcohol.
Unilateral Sensorimotor Cortex Lesions in Adult Rats Facilitate Motor Skill Learning with the “Unaffected” Forelimb and Training-Induced Dendritic Structural Plasticity in the Motor Cortex (2002)

In humans and other animals, sufficient unilateral damage to the sensorimotor cortex can cause impairments in the opposite forelimb and the development of a hyper-reliance on the nonimpaired limb. This hyper-reliance is adaptive to the extent that it contributes to functional compensation for lesion-induced impairments. We have found that unilateral lesions of the forelimb region of the sensorimotor cortex (FLsmc) in rats, or callosal transections, cause neurons of the opposite motor cortex to become exceptionally responsive to changes in forelimb behavior. This enhanced responsiveness might facilitate learning of compensatory strategies with the nonimpaired forelimb after unilateral FLsmc lesions. The possibility that these lesions facilitate learning with the nonimpaired forelimb was addressed in this study. Rats were required to learn a skilled forelimb reaching task after either unilateral FLsmc lesions or sham operations. The trained limb in animals with lesions was the nonimpaired limb. Compared with shams, rats with unilateral lesions had a greater rate of acquisition and asymptotic performance level on the task, which was especially evident on more difficult trials. Quantitative measures of microtubule associated protein-2 (MAP2) immunostained dendrites indicated an enhancement of training-induced dendritic cytoskeletal changes in the motor cortex opposite lesions. Thus, unilateral FLsmc lesions facilitate learning of at least some types of motor skills using the nonimpaired forelimb as well as some of the neuronal changes associated with this learning. This facilitation could be a substrate underlying behavioral compensation for unilateral FLsmc damage and may contribute to the phenomenon of learned nonuse of the impaired limb.
Airway Reconstruction With Carrier‐Free Cell Sheets Composed of Autologous Nasal Squamous Epithelium (2007)

We suggest that autologous cultured nasal squamous epithelium, which differentiates into mucociliary epithelium after in vivo grafting, can be used as a clinically relevant substitute for skin graft in airway luminal reconstruction.

CHOP/GADD153 is a mediator of apoptotic death in substantia nigra dopamine neurons in an <i>in vivo</i> neurotoxin model of parkinsonism (2005)

There is increasing evidence that neuron death in neurodegenerative diseases, such as Parkinson's disease, is due to the activation of programmed cell death. However, the upstream mediators of cell death remain largely unknown. One approach to the identification of upstream mediators is to perform gene expression analysis in disease models. Such analyses, performed in tissue culture models induced by neurotoxins, have identified up-regulation of CHOP/GADD153, a transcription factor implicated in apoptosis due to endoplasmic reticulum stress or oxidative injury. To evaluate the disease-related significance of these findings, we have examined the expression of CHOP/GADD153 in neurotoxin models of parkinsonism in living animals. Nuclear expression of CHOP protein is observed in developmental and adult models of dopamine neuron death induced by intrastriatal injection of 6-hydroxydopamine (6OHDA) and in models induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). CHOP is a mediator of neuron death in the adult 60HDA model because a null mutation results in a reduction in apoptosis. In the chronic MPTP model, however, while CHOP is robustly expressed, the null mutation does not protect from the loss of neurons. We conclude that the role of CHOP depends on the nature of the toxic stimulus. For 6OHDA, an oxidative metabolite of dopamine, it is a mediator of apoptotic death.
Motion artifact detection and correction in functional near-infrared spectroscopy: a new hybrid method based on spline interpolation method and Savitzky–Golay filtering (2018)

Motion artifact contamination in near-infrared spectroscopy (NIRS) data has become an important challenge in realizing the full potential of NIRS for real-life applications. Various motion correction algorithms have been used to alleviate the effect of motion artifacts on the estimation of the hemodynamic response function. While smoothing methods, such as wavelet filtering, are excellent in removing motion-induced sharp spikes, the baseline shifts in the signal remain after this type of filtering. Methods, such as spline interpolation, on the other hand, can properly correct baseline shifts; however, they leave residual high-frequency spikes. We propose a hybrid method that takes advantage of different correction algorithms. This method first identifies the baseline shifts and corrects them using a spline interpolation method or targeted principal component analysis. The remaining spikes, on the other hand, are corrected by smoothing methods: Savitzky-Golay (SG) filtering or robust locally weighted regression and smoothing. We have compared our new approach with the existing correction algorithms in terms of hemodynamic response function estimation using the following metrics: mean-squared error, peak-to-peak error ([Formula: see text]), Pearson's correlation ([Formula: see text]), and the area under the receiver operator characteristic curve. We found that spline-SG hybrid method provides reasonable improvements in all these metrics with a relatively short computational time. The dataset and the code used in this study are made available online for the use of all interested researchers.
Design and Improvement of the Build To Order System with the Convenience in Selection of Personal Computer Components (2006)

Build to order (BTO) systems are generally used as systems for corporate to manage production or systems for the consumers to customize components. This paper discusses the BTO system for consumers which can decide the specifications easily. The present BTO systems for personal computers can customize a construction of the personal computers on the Web in compliance with users' requests. However, there are many expert consumers who feel that the BTO systems are not satisfy with their requests because components of PC prepared in the system are not many enough to choose. In contrast, beginner users do not have enough knowledge of making selection PC components; therefore it is very difficult for them to use the systems without mistaking. This research develops a BTO system built on the web that includes an information database on a huge number of various PC components and a function that can choose the combination of PC components automatically. As a result, expert users can make a PC of best performance capabilities. Moreover, beginner users become possible to select a construction of the PC easily and automatically only by providing the purpose and the budget

Second Messenger Pas de Deux: The Coordinated Dance Between Calcium and cAMP (2006)

Dynamic calcium signaling is a well-established precept in biology. Different cell types exhibit spontaneous as well as stimulus-triggered transient changes in the concentration of intracellular calcium. Does this behavior extend to other second messengers? Optical dissection of various signal transduction pathways with fluorescent reporter molecules that enable visualization of changes in concentration of other second messengers is well under way. Recent research using technologically refined probes provides improved temporal and spatial resolution of adenosine 3',5'-monophosphate (cAMP) dynamics to generate insights into the bidirectional interplay between intracellular fluctuations of cAMP and calcium. cAMP oscillations are generated in response to hormones, and cells can recognize and differentially respond to transient versus sustained changes in this second messenger. Second messenger reporters are now available to track multiple players and so provide a dynamic picture of signaling networks.
An improved design for stretched-membrane heliostats (1989)

Science Applications International Corporation (SAIC) has developed an improved stretched-membrane heliostat mirror module under contract to Sandia National Laboratories, Albuquerque, New Mexico. Both a 150-m/sup 2/ commercial mirror module and a 50-m/sup 2/ prototype mirror module have been designed. The prototype mirror module has been fabricated and is being tested at the Central Receiver Test Facility (CRTF) in Albuquerque. Two .0762-mm (.003-in) thick stainless steel membranes are stressed to approximately 90 MPa (13,000 psi) and welded to either side of a carbon steel, rectangular cross-section ring, which is compressed to approximately one-tenth of its yield strength. The ring is supported by five trusses, which radiate from a central hub. The mirror module is mounted on a conventional pedestal drive system for sun-tracking purposes. The mirror module is air-tight, and focusing is achieved by modulating the position of the back membrane. The ring stiffness and tolerance achievable by conventional manufacturing methods dictate the ring distortions prior to installation of the mirror module. Once the mirror module is installed, wind loads on the heliostat exert additional out-of-plane loads. A comprehensive finite-element computer model of the mirror module was used for the structural design of the ring/membrane system and truss supports. The analysis and design methods used are reported, and an improved mirror module design is described. Preliminary test results indicate the prototype mirror module meets all design performance goals. The unit has a full cone angle reflected beam dispersion of 2.8 mrad and can defocus in five seconds. 25 refs., 77 figs., 17 tabs.

Detection of Cellular Parameters Using a Microfluidic Chip-Based System (2002)

Lab-on-a-chip technology achieves a reduction of sample and reagent volume and automates complex laboratory processes. Here, we present the implementation of cell assays on a microfluidic platform using disposable microfluidic chips. The applications are based on the controlled movement of cells by pressure-driven flow inside networks of microfluidic channels. Cells are hydrodynamically focused and pass the fluorescence detector in single file. Initial applications are the determination of protein expression and apoptosis parameters. The microfluidic system allows unattended measurement of six samples per chip. Results obtained with the microfluidic chips showed good correlation with data obtained using a standard flow cytometer.
