Transient electrical activity accompanying rock under indentation loading

Enomoto, Y. and Hashimoto, H., 1992. Transient electrical activity accompanying rock under indentation loading. In: T. Mikumo, K. Aki, M. Ohnaka, L.J. Ruff and P.K.P. Spudich (Editors), Earthquake Source Physics and Earthquake Precursors. Tectonophysics, 211: 337-344. Laboratory experiments have been conducted to investigate the geoelectrodynamics associated with rock fractures in the earth's crust. That is, when rocks were subjected to indentation fracturing in two ways, the electric charges generated were detected; namely, (1) a direct charge collection method using an electroconductive indenter serving as the collecting electrode (referred to as near-field test), and (2) an indirect collection method in which an electrode was placed on rocks at a specific distance from the indentation fracture zone (referred to as far-field test). As near-field test results, higher electric charge signals were detected during the loading cycle when cracking occurred around the indent on granite and on moist andesite. Also in the far-field test, the charge signal propagating through the rock during fracturing could be detected; the signal intensity decreased as the distance between the indent and electrode increased. Possible mechanisms for fracture-induced charge generation and their propagation through rock media are discussed.

Sudden synchrony leaps accompanied by frequency multiplications in neuronal activity.  

PubMed

A classical view of neural coding relies on temporal firing synchrony among functional groups of neurons, however, the underlying mechanism remains an enigma. Here we experimentally demonstrate a mechanism where time-lags among neuronal spiking leap from several tens of milliseconds to nearly zero-lag synchrony. It also allows sudden leaps out of synchrony, hence forming short epochs of synchrony. Our results are based on an experimental procedure where conditioned stimulations were enforced on circuits of neurons embedded within a large-scale network of cortical cells in vitro and are corroborated by simulations of neuronal populations. The underlying biological mechanisms are the unavoidable increase of the neuronal response latency to ongoing stimulations and temporal or spatial summation required to generate evoked spikes. These sudden leaps in and out of synchrony may be accompanied by multiplications of the neuronal firing frequency, hence offering reliable information-bearing indicators which may bridge between the two principal neuronal coding paradigms.

Human neuromuscular adaptations that accompany changes in activity.  

PubMed

Neuromuscular adaptations probably occur at all levels of the motor pathway, following changes in muscular activity. Adaptations have been mostly investigated in muscle fibers after heavy-resistance and endurance training. In strength training the rapid improvement is due to poorly understood neural factors, with muscle fiber hypertrophy occurring rather later; fiber hyperplasia is probably unimportant. In contrast to other mammals, muscle fibers in humans do not readily change from "slow" to "fast" and vice versa, although there may be a period of plasticity in infancy especially responsive to weightbearing. A proportion of the changes in the fibers, following training, is probably brought about by stretch-activated mechanisms, in which second messengers express immediate early genes and the latter, in turn, promote the transcription of "muscle" genes; other cellular adaptations occur at the level of mRNA translation. In the spinal cord, adaptations following hemiparesis include a loss of functioning motor units. Impaired motor drive occurs not only in organic brain lesions but also after periods of disuse. In persons with amputations, the peripheral nerve stump undergoes degenerative changes; somatosensory cortical evoked responses, following stimulation of the stump, are diminished. It is possible that both sensory and motor cortical representations are increased for neighboring regions of the body. PMID:7869885

Sample classroom activities based on climate science  

NASA Astrophysics Data System (ADS)

We present several activities developed for the middle school education based on a climate science. The first activity was designed to teach about the ocean acidification. A simple experiment can prove that absorption of CO2 in water increases its acidity. A liquid pH indicator is suitable for the demonstration in a classroom. The second activity uses data containing coordinates of a hurricane position. Pupils draw a path of a hurricane eye in a tracking chart (map of the Atlantic ocean). They calculate an average speed of the hurricane, investigate its direction and intensity development. The third activity uses pictures of the Arctic ocean on September when ice extend is usually the lowest. Students measure the ice extend for several years using a square grid printed on a plastic foil. Then they plot a graph and discuss the results. All these activities can be used to improve the natural science education and increase the climate change literacy.

Active Learning in the Physics Classroom  

NASA Astrophysics Data System (ADS)

Many students enter physics classes filled with misconceptions about physics concepts. Students tend to retain these misconceptions into their adult lives, even after physics instruction. Constructivist researchers have found that students gain understanding through their experiences. Researchers have also found that active learning practices increase conceptual understanding of introductory physics students. This project study sought to examine whether incorporating active learning practices in an advanced placement physics classroom increased conceptual understanding as measured by the force concept inventory (FCI). Physics students at the study site were given the FCI as both a pre- and posttest. Test data were analyzed using two different methods---a repeated-measures t test and the Hake gain method. The results of this research project showed that test score gains were statistically significant, as measured by the t test. The Hake gain results indicated a low (22.5%) gain for the class. The resulting project was a curriculum plan for teaching the mechanics portion of Advanced Placement (AP) physics B as well as several active learning classroom practices supported by the research. This project will allow AP physics teachers an opportunity to improve their curricular practices. Locally, the results of this project study showed that research participants gained understanding of physics concepts. Social change may occur as teachers implement active learning strategies, thus creating improved student understanding of physics concepts.

Cultural ecology of dietary change accompanying changing activity patterns among the Shipibo  

SciTech Connect

Shipibo Indians, who formed a village to establish a school and health clinic, are gradually depleting local fish and game resources. Men, recently adopting rice as a cash crop, tend to fish and hunt less than other men working only their subsistence gardens. Sale of fish and game in the village is becoming common, and pigs, once raised exclusively for sale to non-Shipibo, are now more regularly eaten and used for attracting agricultural labor. Other research has indicated that cash cropping often competes for workers' time in subsistence and so dietary change usually accompanies changing activity patterns. This paper explores the latter possibility by examining the relationship between cash cropping, wild meat procurement, and diet among the Shipibo. Time allocation and food consumption data are analyzed statistically to test a mathematical theory and model which relates indigenous work patterns to diet.

Brown adipose tissue function is accompanied by cerebral activation in lean but not in obese humans.  

PubMed

Brown adipose tissue (BAT) is able to generate heat and dissipate energy in response to cold exposure in mammals. It has recently been acknowledged that adult humans also have functional BAT, whose metabolic activity is reduced in obesity. In healthy humans, the cerebral mechanisms that putatively control BAT function are unclear. By using positron emission tomography (PET), we showed that cold-induced BAT activation is associated with glucose metabolism in the cerebellum, thalamus, and cingulate, temporoparietal, lateral frontal, and occipital cortices in lean participants, whereas no such associations were found under warm control conditions. The cold-induced increase in cerebral glucose metabolism was more robust in lean than obese participants. Cerebral glucose metabolism was not associated with skeletal muscle or white adipose tissue glucose uptake under warm or cold conditions. In conclusion, BAT metabolism was accompanied by the activation of specific cerebral regions, and this shows an uncharacterized role that the brain plays in the regulation of BAT function. In obese participants, the cold-induced response in cerebral activity was attenuated that provides a clue for obesity-induced impairment in BAT metabolism. PMID:24667912

NSDL National Science Digital Library

This unique activity presents eleven interactive challenges designed to help students understand the language of motion. Each challenge requires the student to match the motion of an animated car to the correct verbal description of that motion. After all matches have been completed, students check their answers and try again in case of a mismatch. Editor's Note: This activity is ideal for promoting constructivism in the secondary science classroom. It offers learners a low-risk environment for building their own understanding of velocity as a vector quantity, positive and negative acceleration, constant speed, and constant acceleration. It can be adapted for use in both middle and high school. The activity sheet allows teachers to insert the animation quickly into existing lessons.

Immunologically active peptides that accompany hen egg yolk immunoglobulin Y: separation and identification.  

PubMed

The protein mixture of cytokine-inducing activity accompanying chicken immunoglobulin Y, named yolkin, consists of several peptides of molecular weight (MW) ranging from over 1 to 35 kDa. Yolkin and its constituent peptides were found to be efficient inducers of interleukin (IL)-1?, IL-6 and IL-10 secretion. N-terminal amino acid sequences of eight of the electrophoretically purified yolkin constituents revealed that all of them are homological to some fragments of the C-terminal domain of vitellogenin II. The fractions of MW about 4 and 12 kDa are free of carbohydrates and start at position 1732 in the vitellogenin amino acid sequence; whereas the other fractions (MW about 16, 19, 23, 29, 32 and 35 kDa) appeared to be glycoproteins corresponding to the amino acid sequence of vitellogenin starting at position 1572. From these data, it is concluded that yolkin most likely represents vitellogenin-derived peptides that possess cytokine-inducing activity and are, at least partially, responsible for such properties of separated immunoglobulin Y preparation. This finding reveals a new role for vitellogenin as a reservoir of polypeptides that may play an important role in the innate immune system of the developing embryo. PMID:23492558

A Tool for Measuring Active Learning in the Classroom  

PubMed Central

Objectives To develop a valid and reliable active-learning inventory tool for use in large classrooms and compare faculty perceptions of active-learning using the Active-Learning Inventory Tool. Methods The Active-Learning Inventory Tool was developed using published literature and validated by national experts in educational research. Reliability was established by trained faculty members who used the Active-Learning Inventory Tool to observe 9 pharmacy lectures. Instructors were then interviewed to elicit perceptions regarding active learning and asked to share their perceptions. Results Per lecture, 13 (range: 4-34) episodes of active learning encompassing 3 (range: 2-5) different types of active learning occurred over 2.2 minutes (0.6-16) per episode. Both interobserver (?87%) and observer-instructor agreement (?68%) were high for these outcomes. Conclusions The Active-Learning Inventory Tool is a valid and reliable tool to measure active learning in the classroom. Future studies are needed to determine the impact of the Active-Learning Inventory Tool on teaching and its usefulness in other disciplines.

Absence of CD14 Delays Progression of Prion Diseases Accompanied by Increased Microglial Activation  

PubMed Central

Prion diseases are fatal neurodegenerative disorders characterized by accumulation of PrPSc, vacuolation of neurons and neuropil, astrocytosis, and microglial activation. Upregulation of gene expressions of innate immunity-related factors, including complement factors and CD14, is observed in the brains of mice infected with prions even in the early stage of infections. When CD14 knockout (CD14?/?) mice were infected intracerebrally with the Chandler and Obihiro prion strains, the mice survived longer than wild-type (WT) mice, suggesting that CD14 influences the progression of the prion disease. Immunofluorescence staining that can distinguish normal prion protein from the disease-specific form of prion protein (PrPSc) revealed that deposition of PrPSc was delayed in CD14?/? mice compared with WT mice by the middle stage of the infection. Immunohistochemical staining with Iba1, a marker for activated microglia, showed an increased microglial activation in prion-infected CD14?/? mice compared to WT mice. Interestingly, accompanied by the increased microglial activation, anti-inflammatory cytokines interleukin-10 (IL-10) and transforming growth factor ? (TGF-?) appeared to be expressed earlier in prion-infected CD14?/? mice. In contrast, IL-1? expression appeared to be reduced in the CD14?/? mice in the early stage of infection. Double immunofluorescence staining demonstrated that CD11b- and Iba1-positive microglia mainly produced the anti-inflammatory cytokines, suggesting anti-inflammatory status of microglia in the CD14?/? mice in the early stage of infection. These results imply that CD14 plays a role in the disease progression by suppressing anti-inflammatory responses in the brain in the early stage of infection.

Active site remodeling accompanies thioester bond formation in the SUMO E1  

PubMed Central

E1 enzymes activate ubiquitin (Ub) and ubiquitin-like (Ubl) proteins in two steps by carboxy-terminal adenylation and thioester bond formation to a conserved catalytic cysteine in the E1 Cys domain. The structural basis for these intermediates remains unknown. Here we report crystal structures for human SUMO E1 in complex with SUMO adenylate and tetrahedral intermediate analogs at 2.45 Å and 2.6 Å, respectively. These structures show that side chain contacts to ATP·Mg are released after adenylation to facilitate a 130 degree rotation of the Cys domain during thioester bond formation that is accompanied by remodeling of key structural elements including the helix that contains the E1 catalytic cysteine, the cross-over and re-entry loops, and refolding of two helices that are required for adenylation. These changes displace side chains required for adenylation with side chains required for thioester bond formation. Mutational and biochemical analyses suggest these mechanisms are conserved in other E1s.

Activity systems in the inquiry classroom  

NASA Astrophysics Data System (ADS)

Inquiry science, as called for by reform-minded organizations such as the National Research Council (1996), offers a platform with the potential for introducing all students to the practice of science while maintaining focus on key concepts and theories. This project followed two small groups as they completed an inquiry unit on genetics at a Midwestern high school. I investigated whether levels of student-to-teacher, student-to-student, student-apparatus, and student-concept connections were approximately equal across all students in each of the two groups. I found differences among students in levels of student-to-teacher, student-to-student, and student-concept connections. From a situated idiopathic perspective, these differences may indicate different levels of opportunity-to-learn. At a more abstract (nomothetic) level, these differences may be due to emergent divisions of labor (roles) within the two groups. From the perspective of Activity Theory (Leont'ev, 1978; Engestrom, 1987), roles serve as important mediators that simultaneously allow the social unit to accomplish its objectives, while shaping the development of participants. I describe three roles that capture modes of participation for students interacting in the small groups, and that may contribute to what Engestrom (2001) calls subject-producing activity systems: networked contributor, social member, and isolate. This paper also describes tools for teachers and researchers to use in identifying levels of mediation and roles as they occur in small groups.

Voluntary activation of ankle muscles is accompanied by subcortical facilitation of their antagonists  

PubMed Central

Flexion and extension movements are organized reciprocally, so that extensor motoneurones in the spinal cord are inhibited when flexor muscles are active and vice versa. During and just prior to dorsiflexion of the ankle, soleus motoneurones are thus inhibited as evidenced by a depression of the soleus H-reflex. It is therefore surprising that soleus motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation (TMS) have been found not to be reduced and even facilitated during a voluntary dorsiflexion. The objective of this study was to investigate if MEPs, evoked by TMS, show a similar facilitation prior to and at the onset of contraction of muscles that are antagonists to the muscle in which the MEP is evoked and if so, examine the origin of such a facilitatory motor programme. Eleven seated subjects reacted to an auditory cue by contracting either the tibialis anterior (TA) or soleus muscle of the left ankle. TMS was applied to the hotspot of TA and soleus muscles on separate days. Stimuli were delivered prior to and at the beginning of contraction. Soleus MEPs were significantly facilitated when TMS was applied 50 ms prior to onset of plantar flexion. Surprisingly, soleus MEPs were also facilitated (although to a lesser extent) at a similar time in relation to the onset of dorsiflexion. TA MEPs were facilitated 50 ms prior to onset of dorsiflexion and neither depressed nor facilitated prior to plantar flexion. No difference was found between the facilitation of the soleus MEP and motor evoked responses to cervicomedullary stimulation prior to dorsiflexion, suggesting that the increased soleus MEPs were not caused by changes at a cortical level. This was confirmed by the observation that short-latency facilitation of the soleus H-reflex by subthreshold TMS was increased prior to plantar flexion, but not prior to dorsiflexion. These findings suggest that voluntary contraction at the ankle is accompanied by preceding facilitation of antagonists by a subcortical motor programme. This may help to ensure that the direction of movement may be changed quickly and efficiently during functional motor tasks.

Classroom Management  

NSDL National Science Digital Library

Perhaps the most important skill a good teacher should possess is the ability to control students. A teacher who can devise fascinating and unique lesson plans for her classroom is useless if she can't get the kids to sit down and listen to her instructions. Unfortunately, many beginning teachers simply are not prepared to manage their classrooms effectively. Managing a classroom means you must teach your students behavior expectations, not just post your rules on the classroom wall. Classroom management becomes even more of an issue when it applies to the active nature of the science classroom.

Transient anabolic effects accompany epidermal growth factor receptor signal activation in articular cartilage in vivo  

PubMed Central

Introduction Signals from the epidermal growth factor receptor (EGFR) have typically been considered to provide catabolic activities in articular cartilage, and accordingly have been suggested to have a causal role in osteoarthritis progression. The aim of this study was to determine in vivo roles for endogenous EGFR signal activation in articular cartilage. Methods Transgenic mice with conditional, limb-targeted deletion of the endogenous intracellular EGFR inhibitor Mig-6 were generated using CreLoxP (Mig-6-flox; Prx1Cre) recombination. Histology, histochemical staining and immunohistochemistry were used to confirm activation of EGFR signaling in the articular cartilage and joints, and to analyze phenotypic consequences of Mig-6 loss on articular cartilage morphology, proliferation, expression of progenitor cell markers, presence of chondrocyte hypertrophy and degradation of articular cartilage matrix. Results The articular cartilage of Mig-6-conditional knockout (Mig-6-cko) mice was dramatically and significantly thicker than normal articular cartilage at 6 and 12 weeks of age. Mig-6-cko articular cartilage contained a population of chondrocytes in which EGFR signaling was activated, and which were three to four times more proliferative than normal Mig-6-flox articular chondrocytes. These cells expressed high levels of the master chondrogenic regulatory factor Sox9, as well as high levels of putative progenitor cell markers including superficial zone protein (SZP), growth and differentiation factor-5 (GDF-5) and Notch1. Expression levels were also high for activated ?-catenin and the transforming growth factor beta (TGF-?) mediators phospho-Smad2/3 (pSmad2/3). Anabolic effects of EGFR activation in articular cartilage were followed by catabolic events, including matrix degradation, as determined by accumulation of aggrecan cleavage fragments, and onset of hypertrophy as determined by type × collagen expression. By 16 weeks of age, the articular cartilage of Mig-6-cko knees was no longer thickened and was degenerating. Conclusions These results demonstrate unexpected anabolic effects of EGFR signal activation in articular cartilage, and suggest the hypothesis that these effects may promote the expansion and/or activity of an endogenous EGFR-responsive cell population within the articular cartilage.

Convulxin-induced platelet aggregation is accompanied by a powerful activation of the phospholipase C pathway.  

PubMed Central

Platelet aggregation and stimulation of phosphoinositide-specific phospholipase C (PLC) by thrombin and by convulxin (Cvx), a non-enzymic snake venom glycoprotein, were compared. Cvx-stimulated production of inositol phosphates by washed platelets was independent of the cyclo-oxygenase pathway, formation of platelet-activating factor and ADP release, but prostacyclin (prostaglandin I2), a stimulator of cyclic AMP formation, suppressed its effects on platelet and PLC activation. Kinetic analysis showed that inositol 1,4,5-trisphosphate formation reached its maximal value 15 s after platelet stimulation with Cvx and persisted for at least 5 min. Neomycin sulphate (10 mM), which complexes phosphatidylinositol 4-phosphate and phosphatidyl-inositol 4,5-bisphosphate, decreased the production of inositol phosphates, partially prevented platelet aggregation induced by a high concentration of Cvx (10 nM) and abolished both platelet aggregation and inositol phosphate formation induced by thrombin (2 units/ml) and by a stable prostaglandin H2 analogue, U46619 (1 microM). In contrast with neomycin sulphate, Na2SO4 had no significant effect against all agonists tested. It is concluded that platelet activation by Cvx is partially mediated by PLC and involves other mechanisms as well.

Oxidative stress status accompanying diabetic bladder cystopathy results in the activation of protein degradation pathways  

PubMed Central

Objectives To investigate the role that oxidative stress plays in the development of diabetic cystopathy. Materials and methods Comparative gene expression in the bladder of non-diabetic and streptozotocin (STZ)-induced 2-month-old diabetic rats was carried out using microarray analysis. Evidence of oxidative stress was investigated in the bladder by analyzing glutathione S-transferase activity, lipid peroxidation, and carbonylation and nitrosylation of proteins. The activity of protein degradation pathways was assessed using western blot analysis. Results Analysis of global gene expression showed that detrusor smooth muscle tissue of STZ-induced diabetes undergoes significant enrichment in targets involved in the production or regulation of reactive oxygen species (P = 1.27 × 10?10). The microarray analysis was confirmed by showing that markers of oxidative stress were all significantly increased in the diabetic bladder. It was hypothesized that the sequelae to oxidative stress would be increased protein damage and apoptosis. This was confirmed by showing that two key proteins involved in protein degradation (Nedd4 and LC3B) were greatly up-regulated in diabetic bladders compared to controls by 12.2 ± 0.76 and 4.4 ± 1.0-fold, respectively, and the apoptosis inducing protein, BAX, was up-regulated by 6.76 ± 0.76-fold. Conclusions Overall, the findings obtained in the present study add to the growing body of evidence showing that diabetic cystopathy is associated with oxidative damage of smooth muscle cells, and results in protein damage and activation of apoptotic pathways that may contribute to a deterioration in bladder function.

Structural and hydration changes in the active site gorge of phosporhylated butyrylcholinesterase accompanying the aging process.  

PubMed

Wild-type (wt) butyrylcholinesterase (BuChE) and the E197D and D70G mutants were inhibited by diisopropylfluorophosphate (DFP) or soman under standard conditions of pH, temperature and pressure. The effect of hydrostatic and osmotic pressures on the aging process of DFP-phosphorylated enzymes (diisopropylphosphoryl-BuChE (DIP-BuChE)) was investigated. Hydrostatic pressure strongly increased the rate of aging of wt enzyme. The activation volumes (deltaV*) for the dealkylation reaction was -150 ml/mol for DIP-wtBuChE. On the other hand, pressure had little effect on the aging of the DIP-E197D mutant and no effect on the DIP-D70G mutant, indicating that the transition state of the aging reaction (dealkylation of an isoproxy chain) was associated with an extended conformation/hydration change in wtBuChE but not in mutants. The rate of aging decreased with osmotic pressure, supporting the idea that water is important for stabilizing the transition state. Molecular dynamics simulations were performed on the wtDIP adduct to relate the kinetic data to hydration changes in the enzyme active site gorge. The pH dependence of the melting temperature (Tm) of native and soman-wtBuChE, as determined by differential scanning calorimetry (DSC), indicated that the stabilization energy of aged BuChE is mainly due to the salt bridge between protonated H438 and PO-, with pK(H438) = 8.3. Electrophoresis under high pressure up to 2.5 kbar showed that aged wtBuChE did not undergo pressure-induced molten globule transition unlike the native enzyme. This transition was not seen for the mutant enzymes, indicating that mutants are resistant to the penetration of water into their structure. Our results support the conclusion that D70 and E197 are major residues for the water/H-bond network dynamics in the active site gorge of BuChE, both residues acting like valves. In mutant enzymes, mutated residues function like check valves: forced penetration of water in the gorge is difficult, release of water is facilitated. PMID:10421435

Major shifts in genomic activity accompany progression through different stages of the hair cycle.  

PubMed

Hair follicles display a unique pattern of cyclic growth and regression involving cell proliferation, differentiation and migration. The molecular details of these processes are largely unexplored. Global expression analyses on the basis of about 20,000 genes for each morphologically distinguishable stage of the hair cycle revealed unexpected complexities of and major temporal shifts in transcriptional programs involving about 13% of all genes. In particular, hundreds of genes characterise the pattern of genomic activity during regression and resting phases; selected genes can be used to monitor hair growth in mice. We demonstrate that temporal expression patterns predict gene expression domains within the hair follicle. Expression of insulin-like growth factor binding proteins and anti-angiogenic factors is associated with the regression phase of the hair cycle. PMID:15161094

Reduced choice-related activity and correlated noise accompany perceptual deficits following unilateral vestibular lesion  

PubMed Central

Signals from the bilateral vestibular labyrinths work in tandem to generate robust estimates of our motion and orientation in the world. The relative contributions of each labyrinth to behavior, as well as how the brain recovers after unilateral peripheral damage, have been characterized for motor reflexes, but never for perceptual functions. Here we measure perceptual deficits in a heading discrimination task following surgical ablation of the neurosensory epithelium in one labyrinth. We found large increases in heading discrimination thresholds and large perceptual biases at 1 wk postlesion. Repeated testing thereafter improved heading perception, but vestibular discrimination thresholds remained elevated 3 mo postlesion. Electrophysiological recordings from the contralateral vestibular and cerebellar nuclei revealed elevated neuronal discrimination thresholds, elevated neurometric-to-psychometric threshold ratios, and reduced trial-by-trial correlations with perceptual decisions [“choice probabilities” (CPs)]. The relationship between CP and neuronal threshold was shallower, but not significantly altered, suggesting that smaller CPs in lesioned animals could be largely attributable to greater neuronal thresholds. Simultaneous recordings from pairs of neurons revealed that correlated noise among neurons was also reduced following the lesion. Simulations of a simple pooling model, which takes into account the observed changes in tuning slope and correlated noise, qualitatively accounts for the elevated psychophysical thresholds and neurometric-to-psychometric ratios, as well as the decreased CPs. Thus, cross-labyrinthine interactions appear to play important roles in enhancing neuronal and perceptual sensitivity, strengthening interneuronal correlations, and facilitating correlations between neural activity and perceptual decisions.

Transcriptional activation of the lipoprotein lipase and apolipoprotein E genes accompanies differentiation in some human macrophage-like cell lines  

SciTech Connect

Stimulation of the macrophage-like cell line THP-1 with the phorbol ester phorbol 12-myristate 13-acetate (PMA) resulted in differentiation into cells with many features of macrophages. This differentiation was accompanied by transcriptional activation of the lipoprotein lipase (LPL) and apo E genes and accumulation of their protein products in the media. PMA-induced differentiation of the HEL and HL-60 cell lines was not accompanied by induction of the gene for LPL, whereas the apo E gene was induced slightly in HL-60 cells. By contrast, the gene for superoxide dismutase (SOD-1) was either unaffected (THP-1) or down regulated (HL-60 or HEL cells) by PMA treatment. Induction of LPL mRNA in THP-1 cells as dependent upon the concentration of phorbol ester added. A minimal concentration of 1.6 x 10/sup -8/ M PMA was necessary for macrophage differentiation, induction of LPL mRNA, and synthesis of the enzyme. LPL mRNA accumulates within 3 h after stimulation with PMA and attains a maximum concentration after 6 h, thereafter slowly decreasing over the next 3 days. In contrast, the steady-state level of apo E mRNA in the same THP-1 cultures increased gradually over a period of 48 h after induction. These studies thus demonstrate that THP-1 cells are of value as a model to study the quantitative and temporal expression of the LPL and apo E genes during macrophage differentiation.

Noncoding RNA synthesis and loss of Polycomb group repression accompanies the colinear activation of the human HOXA cluster  

PubMed Central

The ratio of noncoding to protein coding DNA rises with the complexity of the organism, culminating in nearly 99% of nonprotein coding DNA in humans. Nevertheless, a large portion of these regions is transcribed, creating the alleged paradox that noncoding RNA (ncRNA) represents the largest output of the human genome. Such a complex scenario may include epigenetic mechanisms where ncRNAs would be involved in chromatin regulation. We have investigated the intergenic, noncoding transcriptomes of mammalian HOX clusters. We show that “opposite strand transcription” from the intergenic spacer regions in the human HOXA cluster correlates with the activity state of adjacent HOXA genes. This noncoding transcription is regulated by the retinoic acid morphogen and follows the colinear activation pattern of the cluster. Opening of the cluster at sites of activation of intergenic transcripts is accompanied by changes in histone modifications and a loss of interaction with Polycomb group (PcG) repressive complexes. We propose that noncoding transcription is of fundamental importance for the opening and maintenance of the active state of HOX clusters.

Hypoxia preconditioning of mesenchymal stromal cells enhances PC3 cell lymphatic metastasis accompanied by VEGFR-3/CCR7 activation.  

PubMed

Mesenchymal stromal cells (MSCs) in bone marrow may enhance tumor metastases through the secretion of chemokines. MSCs have been reported to home toward the hypoxic tumor microenvironment in vivo. In this study, we investigated prostate cancer PC3 cell behavior under the influence of hypoxia preconditioned MSCs and explored the related mechanism of prostate cancer lymphatic metastases in mice. Transwell assays revealed that VEGF-C receptor, VEGFR-3, as well as chemokine CCL21 receptor, CC chemokine receptor 7 (CCR7), were responsible for the migration of PC3 cells toward hypoxia preconditioned MSCs. Knock-in Ccr7 in PC3 cells also improved cell migration in vitro. Furthermore, when PC3 cells were labeled using the hrGfp-lentiviral vector, and were combined with hypoxia preconditioned MSCs for xenografting, it resulted in an enhancement of lymph node metastases accompanied by up-regulation of VEGFR-3 and CCR7 in primary tumors. Both PI3K/Akt/I?B? and JAK2/STAT3 signaling pathways were activated in xenografts in the presence of hypoxia-preconditioned MSCs. Unexpectedly, the p-VEGFR-2/VEGFR-2 ratio was attenuated accompanied by decreased JAK1 expression, indicating a switching-off of potential vascular signal within xenografts in the presence of hypoxia-preconditioned MSCs. Unlike results from other studies, VEGF-C maintained a stable expression in both conditions, which indicated that hypoxia preconditioning of MSCs did not influence VEGF-C secretion. Our results provide the new insights into the functional molecular events and signalings influencing prostate tumor metastases, suggesting a hopeful diagnosis and treatment in new approaches.

An Inquiry "Warm-Up" Activity: Preparing Students for an Active Classroom Community  

NASA Astrophysics Data System (ADS)

An active learning community that engages in inquiry activities will employ strategies and structures that students from traditional classrooms may find unfamiliar or uncomfortable. These include group work, voicing questions, shifting from one part of an activity to another (and sometimes shifting groups at the same time), presenting informally to the group, and many others. In addition, the role of the instructor as facilitator rather than teacher may not be familiar to students. As inquiry activities become incorporated into the regular classroom curriculum at Maui Community College (through collaboration with the Professional Development Program as part of the Akamai Workforce Initiative), a need emerged to give students a "warm-up" early in the semester to help them practice these participation structures. This activity was designed to be used on the very first day of class, to be easy and accessible to students, and to give them practice with these features of inquiry activities that they would see again throughout the semester. In addition, the activity introduces the engineering technology concepts of requirements, trade-offs, and limitations. It is important to note that this activity is not in and of itself an inquiry activity; in fact the content and processes featured in the activity are not particularly challenging nor are they the main focus. Instead, this is a "warm-up" for inquiry, so that students gain some comfort with the unconventional features of inquiry activities. The particular activity presented is for 20-30 students in a ˜90 minute lab period, and highlights different imaging technologies of cameras; however, it is easily adaptable to other requirements, to different technology, or other needs.

Biphasic induction of immediate early gene expression accompanies activity-dependent angiogenesis and myofiber remodeling of rabbit skeletal muscle.  

PubMed Central

Sustained contractile activity of skeletal muscle promotes angiogenesis, as well as transformation of contractile protein isoforms and mitochondrial proliferation within myofibers. Since the products of immediate early genes such as c-fos, c-jun, and egr-1 function in many signaling pathways governing cellular responses to external stimuli, we sought to determine whether sustained contractile activity induces their expression in skeletal muscle. Low voltage electrical stimulation was applied to the motor nerve innervating rabbit tibialis anterior muscles for periods ranging from 45 min to 21 d. Northern and Western analysis demonstrated marked but transient inductions of c-fos, c-jun, and egr-1 mRNA and protein within the first 24 h. Longer durations of stimulation were associated with a secondary and sustained rise in the abundance of c-fos, c-jun, and p88egr-1 protein that, surprisingly, was not accompanied by detectable changes in mRNA. Immunohistochemistry demonstrated c-fos immunoreactivity within myofiber and vascular cell nuclei during both early and late phases of this response. These findings reveal a complex pattern of c-fos, c-jun, and egr-1 expression in response to nerve stimulation and suggest that these proteins could function in regulatory pathways that modify muscle phenotype.

Induction of a retinoblastoma phosphatase activity by anticancer drugs accompanies p53-independent G1 arrest and apoptosis.  

PubMed Central

DNA-damaging agents induce accumulation of the tumor suppressor and G1 checkpoint protein p53, leading cells to either growth arrest in G1 or apoptosis (programmed cell death). The p53-dependent G1 arrest involves induction of p21 (also called WAF1/CIP1/SDI1), which prevents cyclin kinase-mediated phosphorylation of retinoblastoma protein (RB). Recent studies suggest a p53-independent G1 checkpoint as well; however, little is known about its molecular mechanisms. We report that induction of a protein-serine/threonine phosphatase activity by DNA damage signals is at least one of the mechanisms responsible for p53-independent, RB-mediated G1 arrest and consequent apoptosis. When two p53-null human leukemic cell lines (HL-60 and U-937) were treated with a variety of anticancer agents, RB became hypophosphorylated, accompanied with G1 arrest. This was followed immediately (in less than 30 min) by apoptosis, as determined by the accumulation of pre-G1 apoptotic cells and the internucleosomal fragmentation of DNA. Addition of calyculin A or okadaic acid (specific serine/threonine phosphatase inhibitors) or zinc chloride (apoptosis inhibitor) prevented the G1 arrest- and apoptosis-specific RB dephosphorylation. The levels of cyclin E- and cyclin A-associated kinase activities remained high during RB dephosphorylation, supporting the involvement of a chemotherapy-induced serine/threonine phosphatase(s) rather than p21. Furthermore, the induced phosphatase activity coimmunoprecipitated with the hyperphosphorylated RB and was active in a cell-free system that reproduced the growth arrest- and apoptosis-specific RB dephosphorylation, which was inhibitable by calyculin A but not zinc. We propose that the RB phosphatase(s) might be one of the p53-independent G1 checkpoint regulators. Images Fig. 1 Fig. 2 Fig. 3 Fig. 4

Regulatory Activation Is Accompanied by Movement in the C Terminus of the Na-K-Cl Cotransporter (NKCC1)*  

PubMed Central

The Na-K-Cl cotransporter (NKCC1) is expressed in most vertebrate cells and is crucial in the regulation of cell volume and intracellular chloride concentration. To study the structure and function of NKCC1, we tagged the transporter with cyan (CFP) and yellow (YFP) fluorescent proteins at two sites within the C terminus and measured fluorescence resonance energy transfer (FRET) in stably expressing human embryonic kidney cell lines. Both singly and doubly tagged NKCC1s were appropriately produced, trafficked to the plasma membrane, and exhibited 86Rb transport activity. When both fluorescent probes were placed within the same C terminus of an NKCC1 transporter, we recorded an 11% FRET decrease upon activation of the transporter. This result clearly demonstrates movement of the C terminus during the regulatory response to phosphorylation of the N terminus. When we introduced CFP and YFP separately in different NKCC1 constructs and cotransfected these in HEK cells, we observed FRET between dimer pairs, and the fractional FRET decrease upon transporter activation was 46%. Quantitatively, this indicates that the largest FRET-signaled movement is between dimer pairs, an observation supported by further experiments in which the doubly tagged construct was cotransfectionally diluted with untagged NKCC1. Our results demonstrate that regulation of NKCC1 is accompanied by a large movement between two positions in the C termini of a dimeric cotransporter. We suggest that the NKCC1 C terminus is involved in transport regulation and that dimerization may play a key structural role in the regulatory process.

Regulatory activation is accompanied by movement in the C terminus of the Na-K-Cl cotransporter (NKCC1).  

PubMed

The Na-K-Cl cotransporter (NKCC1) is expressed in most vertebrate cells and is crucial in the regulation of cell volume and intracellular chloride concentration. To study the structure and function of NKCC1, we tagged the transporter with cyan (CFP) and yellow (YFP) fluorescent proteins at two sites within the C terminus and measured fluorescence resonance energy transfer (FRET) in stably expressing human embryonic kidney cell lines. Both singly and doubly tagged NKCC1s were appropriately produced, trafficked to the plasma membrane, and exhibited (86)Rb transport activity. When both fluorescent probes were placed within the same C terminus of an NKCC1 transporter, we recorded an 11% FRET decrease upon activation of the transporter. This result clearly demonstrates movement of the C terminus during the regulatory response to phosphorylation of the N terminus. When we introduced CFP and YFP separately in different NKCC1 constructs and cotransfected these in HEK cells, we observed FRET between dimer pairs, and the fractional FRET decrease upon transporter activation was 46%. Quantitatively, this indicates that the largest FRET-signaled movement is between dimer pairs, an observation supported by further experiments in which the doubly tagged construct was cotransfectionally diluted with untagged NKCC1. Our results demonstrate that regulation of NKCC1 is accompanied by a large movement between two positions in the C termini of a dimeric cotransporter. We suggest that the NKCC1 C terminus is involved in transport regulation and that dimerization may play a key structural role in the regulatory process. It is anticipated that when combined with structural information, our findings will provide a model for understanding the conformational changes that bring about NKCC1 regulation. PMID:22121194

Chromatin condensation during apoptosis is accompanied by degradation of lamin A+B, without enhanced activation of cdc2 kinase  

PubMed Central

Chromatin condensation paralleled by DNA fragmentation is one of the most important criteria which are used to identify apoptotic cells. However, comparable changes are also observed in interphase nuclei which have been treated with cell extracts from mitotic cells. In this respect it is known that in mitosis, the lamina structure is broken down as a result of lamin solubilization and it is possible that a similar process is happening in apoptotic cells. The experiments described in this study have used confluent cultures of an embryonic fibroblast cell line which can be induced to undergo either apoptosis at low serum conditions or mitosis. Solubilization of lamin A+B was analyzed by immunoblotting and indirect immunofluorescence. These studies showed that in mitotic cells lamina breakdown is accompanied by lamin solubilization. In apoptotic cells, a small amount of lamin is solubilized before the onset of apoptosis, thereafter, chromatin condensation is accompanied by degradation of lamin A+B to a 46-kD fragment. Analysis of cellular lysates by probing blots with anti- PSTAIR followed by anti-phosphotyrosine showed that in contrast to mitosis, dephosphorylation on tyrosine residues did not occur in apoptotic cells. At all timepoints after the onset of apoptosis there was no significant increase in the activation of p34cdc2 as determined in the histone H1 kinase assay. Coinduction of apoptosis and mitosis after release of cells from aphidicolin block showed that apoptosis could be induced in parallel with S-phase. The sudden breakdown of chromatin structure may be the result of detachment of the chromatin loops from their anchorage at the nuclear matrix, as bands of 50 kbp and corresponding multimers were detectable by field inversion gel electrophoresis (FIGE). In apoptotic cells all of the DNA was fragmented, but only 14% of the DNA was smaller than 50 kbp. DNA strand breaks were detected at the periphery of the condensed chromatin by in situ tailing (ISTAIL). Chromatin condensation during apoptosis appears to be due to a rapid proteolysis of nuclear matrix proteins which does not involve the p34cdc2 kinase.

H2Oh!: Classroom demonstrations and activities for improving student learning of water concepts  

NASA Astrophysics Data System (ADS)

Research has shown that the use of demonstrations and hands-on activities in the classroom enhances student learning. Students learn more and enjoy classes more when visual and active learning are incorporated into the lecture. Most college-aged students prefer visual modes of learning, while most instruction is conducted in a lecture, or auditory, format. The use of classroom demonstrations provides opportunities for incorporating visual and active learning into the classroom environment. However, while most instructors acknowledge the benefits of these teaching methods, they typically do not have the time and resources to develop and test such activities and to develop plans to incorporate them into their lectures. Members of the Excellence in Water Resources Education Task Committee of the Environmental and Water Resources Institute (EWRI) of the American Society of Civil Engineers (ASCE) have produced a publication that contains a collection of activities aimed to foster excellence in water resources and hydrology education and improve student learning of principles. The book contains forty-five demonstrations and activities that can be used in water-related classes with topics in fluid mechanics, hydraulics, surface water hydrology, groundwater hydrology, and water quality. We present examples of these activities, including topics such as conservation of momentum, buoyancy, Bernoulli's principle, drag force, pipe flow, watershed delineation, reservoir networks, head distribution in aquifers, and molecular diffusion in a porous medium. Unlike full laboratory exercises, these brief demonstrations and activities (most of which take less than fifteen minutes) can be easily incorporated into classroom lectures. For each demonstration, guidance for preparing and conducting the activity, along with a brief overview of the principles that are demonstrated, is provided. The target audience of the activities is undergraduate students, although the activities also may be used in K-12 and graduate classes.

Vodcasts and Active-Learning Exercises in a "Flipped Classroom" Model of a Renal Pharmacotherapy Module  

PubMed Central

Objective. To implement a “flipped classroom” model for a renal pharmacotherapy topic module and assess the impact on pharmacy students’ performance and attitudes. Design. Students viewed vodcasts (video podcasts) of lectures prior to the scheduled class and then discussed interactive cases of patients with end-stage renal disease in class. A process-oriented guided inquiry learning (POGIL) activity was developed and implemented that complemented, summarized, and allowed for application of the material contained in the previously viewed lectures. Assessment. Students’ performance on the final examination significantly improved compared to performance of students the previous year who completed the same module in a traditional classroom setting. Students’ opinions of the POGIL activity and the flipped classroom instructional model were mostly positive. Conclusion. Implementing a flipped classroom model to teach a renal pharmacotherapy module resulted in improved student performance and favorable student perceptions about the instructional approach. Some of the factors that may have contributed to students’ improved scores included: student mediated contact with the course material prior to classes, benchmark and formative assessments administered during the module, and the interactive class activities.

Teachers' scientific knowledge, teaching practice, and students' learning activities: Cases of three elementary classroom teachers  

NASA Astrophysics Data System (ADS)

The purposes of this dissertation study are to better understand what specific types of scientific knowledge and practice three elementary teachers exhibit, and to examine how they use their scientific knowledge in their classroom teaching practice to provide students' opportunities to learn science when teaching condensation in the context of a unit on the water cycle. By comparing and contrasting three cases of elementary classroom teaching, this study discusses what kinds of scientific knowledge and practice are fundamental for teaching elementary science for scientific understanding. The data include structured interviews (content, pre- and post- observation, and stimulated recall), videotaped classroom observations, and collections of teachers' and students' written artifacts. Data were collected prior to, during, and after the three teachers taught condensation to fifth grade students. The data were analyzed in three contexts: interviews, teaching practices, and students' classroom activities. This made it possible to clarify which characteristics of teacher's scientific knowledge influenced which aspects of their teaching practice. Data analysis shows that teachers' scientific knowledge were closely associated with their teaching practice and students' classroom activities. Two characteristics of the teachers' scientific reasoning emerged as especially important. The first concerned how teachers connected observations of condensation with patterns in those observations (e.g., condensation occurs when warm moist air cools) and with explanations for those patterns (e.g., condensation is water vapor that changes to liquid water). Two teachers were careful to connect observations with patterns in their own thinking and in their classroom teaching. One of those teachers also connected the observations and patterns to scientific explanations. In contrast, the third teacher focused on listing scientific terms with little elaboration with specific observations and patterns. The second important characteristic of teachers' scientific reasoning concerned their views of science. One teacher enacted a largely inductive, empirical view, helping her students to observe examples of condensation, to find patterns in their observations, and to label the patterns as condensation. The second teacher engaged the students in a detailed series of experiments and data-based arguments designed to demonstrate that the liquid water in condensation was originally water vapor in the air. The third teacher focused on teaching students facts and vocabulary from authoritative sources, including their textbook and dictionaries. This study discusses what it means to have a deep understanding of fundamental science for elementary teachers. Making connections among observations, patterns, and explanations is important for students to understand the scientific world. Scientific practices, inquiry and application, play an important role to help teachers and students connect observations, patterns, and explanations. The implications to elementary science teacher education are discussed, considering how we can prepare elementary teachers to use scientific knowledge in their teaching practice.

Active Learning in a Large General Physics Classroom.  

NASA Astrophysics Data System (ADS)

In 2004, we launched a new calculus-based, introductory physics sequence at Washington University. Designed as an alternative to our traditional lecture-based sequence, the primary objectives for this new course were to actively engage students in the learning process, to significantly strengthen students' conceptual reasoning skills, to help students develop higher level quantitative problem solving skills necessary for analyzing ``real world'' problems, and to integrate modern physics into the curriculum. This talk will describe our approach, using The Six Ideas That Shaped Physics text by Thomas Moore, to creating an active learning environment in large classes as well as share our perspective on key elements for success and challenges that we face in the large class environment.

THE EFFECTS OF EXERGAMING ON PHYSICAL ACTIVITY AMONG INACTIVE CHILDREN IN A PHYSICAL EDUCATION CLASSROOM  

PubMed Central

Childhood obesity, which is due in part to lack of physical activity, is a serious concern that requires the attention of the behavioral community. Although excessive video game play has been noted in the literature as a contributor to childhood obesity, newer video gaming technology, called exergaming, has been designed to capitalize on the reinforcing effects of video games to increase physical activity in children. This study evaluated the effects of exergaming on physical activity among 4 inactive children in a physical education (PE) classroom. Results showed that exergaming produced substantially more minutes of physical activity and more minutes of opportunity to engage in physical activity than did the standard PE program. In addition, exergaming was socially acceptable to both the students and the PE teacher. Exergaming appears to hold promise as a method for increasing physical activity among inactive children and might be a possible intervention for childhood obesity.

Creating Classroom Activities About Ocean Drilling Geophysics Through Scientist-Teacher Collaboration  

NASA Astrophysics Data System (ADS)

How can examples of geophysical data used in research be effectively taught to middle and high school students with only general science knowledge? Logging data, or logs, are continuous measurements of physical properties made in situ and at high resolution by lowering instruments into boreholes after completion of coring. As part of the Integrated Ocean Drilling Program (IODP) "School of Rock 2007" (http://www.joilearning.org/schoolofrock2007), we created a classroom activity to introduce pre-college students to representative logging data collected by the R/V JOIDES Resolution during expeditions of the Ocean Drilling Program (ODP) and the Integrated Ocean Drilling Program (IODP). The synergistic model for curriculum development involving a research scientist (Guerin) and classroom teacher (Passow) provides an efficient strategy to disseminate technical research methods and results more widely with students and teachers. The "School of Rock 2007" brought 18 educators and 12 scientists together at the Texas A and M IODP Gulf Coast Observatory for a week in July to learn about techniques in sea floor exploration and advances in understanding the Earth's climate using geophysics, biostratigraphy, geomagnetics, and more. Teachers and researchers then collaborated to produce classroom activities that will add to the existing collection of educational resources available through JOI Learning (http://www.joiscience.org/learning). The activity we developed introduces students to general concepts of downhole logging, then presents sample data from three sites. Using guiding information provided, students engage in simplified interpretation of the data to identify such features as sedimentary layers, igneous rocks, or gas hydrate-bearing formations. Activities include questions about geography, identifying patterns within the data, recognizing distinctive features in gamma ray, resistivity, density and porosity logs. The curriculum materials will be tested with students and teachers in various setting during Fall 2007, including as part of the Earth2Class Workshops for Teachers (http://www.earth2class.org) and the Lamont-Doherty Earth Observatory Open House (http://www.ldeo.columbia.edu.)

DNA distortion accompanies transcriptional activation by the metal-responsive gene-regulatory protein MerR  

SciTech Connect

Transcriptional regulation of the bacterial mercuric ion resistance operon (mer) in response to nanomolar concentrations of mercuric ion is achieved by the allosterically modulated transcriptional activator protein MerR. The authors now show that mercuric ion modification of MerR activates transcription, facilitating the conversion of an RNA polymerase complex with the mer promoter from the closed conformation to the strand-separated, transcriptionally competent open complex. An Hg-MerR-induced structural alteration at the center of the promoter has been detected in the presence or absence of RNA polymerase by use of chemical nucleases sensitive to variations in DNA secondary structure. This hypersensitivity correlates directly with transcriptional activation, lending further support to a previous proposal that a protein-induced distortion in local DNA structure can be the key step in an allosterically modulated transcription activation mechanism.

Activation of sea-urchin sperm motility is accompanied by an increase in the creatine kinase exchange flux.  

PubMed Central

The kinetics of the creatine kinase (CK) reaction were studied in suspensions of quiescent and active, intact sea-urchin spermatozoa in artificial seawater, using 31P-NMR magnetization transfer. In inactive sperm, no CK-mediated exchange flux was detected, whereas in activated motile sperm, the forward pseudo-first-order rate constant was 0.13+/-0.04 s-1 at 10 degrees C, corresponding to a steady-state CK flux of 3.1+/-0.5 mM.s-1. Intracellular pH shifted from 6.6+/-0.1 to 7.6+/-0.1 upon activation. The phosphocreatine (PCr)/ATP and PCr/Pi ratios were only marginally reduced in activated sperm, whereas the estimated cytosolic free ADP concentration increased remarkably from 9 microM in quiescent, to 114 microM in activated spermatozoa. The elevation of CK flux upon sperm activation is discussed in the light of the proposition that in sea-urchin spermatozoa, which are fuelled entirely by oxidative phosphorylation, high-energy phosphate transport is mediated by a 'CK/PCr shuttle'.

An Increase in Pectin Methyl Esterase Activity Accompanies Dormancy Breakage and Germination of Yellow Cedar Seeds1  

PubMed Central

Pectin methyl esterase (PME) (EC 3.1.1.11) catalyzes the hydrolysis of methylester groups of cell wall pectins. We investigated the role of this enzyme in dormancy termination and germination of yellow cedar (Chamaecyparis nootkatensis [D. Don] Spach) seeds. PME activity was not detected in dormant seeds of yellow cedar but was induced and gradually increased during moist chilling; high activity coincided with dormancy breakage and germination. PME activity was positively correlated to the degree of dormancy breakage of yellow cedar seeds. The enzyme produced in different seed parts and in seeds at different times during moist chilling, germination, and early post-germinative growth consisted of two isoforms, both basic with isoelectric points of 8.7 and 8.9 and the same molecular mass of 62 kD. The pH optimum for the enzyme was between 7.4 and 8.4. In intact yellow cedar seeds, activities of the two basic isoforms of PME that were induced in embryos and in megagametophytes following dormancy breakage were significantly suppressed by abscisic acid. Gibberellic acid had a stimulatory effect on the activities of these isoforms in embryos and megagametophytes of intact seeds at the germinative stage. We hypothesize that PME plays a role in weakening of the megagametophyte, allowing radicle emergence and the completion of germination.

Formation of activity cliffs is accompanied by systematic increases in ligand efficiency from lowly to highly potent compounds.  

PubMed

Activity cliffs (ACs) are defined as pairs of structurally similar compounds sharing the same biological activity but having a large difference in potency. Therefore, ACs are often studied to rationalize structure-activity relationships (SARs) and aid in lead optimization. Hence, the AC concept plays an important role in compound development. For compound optimization, ligand efficiency (LE) represents another key concept. LE accounts for the relation between compound potency and mass. A major goal of lead optimization is to increase potency and also LE. Despite their high relevance for drug development, the AC and LE concepts have thus far not been considered in combination. It is currently unknown how compounds forming ACs might be related in terms of LE. To explore this question, ACs were systematically identified on the basis of high-confidence activity data and LE values for cliff partners were determined. Surprisingly, a significant increase in LE was generally detected for highly potent cliff partners compared to their lowly potent counterparts, regardless of the compound classes and their targets. Hence, ACs reveal chemical modifications that determine SARs and improve LE. These findings further increase the attractiveness of AC information for compound optimization and development.

The isomorphous structures of prethrombin2, hirugen-, and PPACK-thrombin: changes accompanying activation and exosite binding to thrombin.  

PubMed Central

The X-ray crystal structure of prethrombin2 (pre2), the immediate inactive precursor of alpha-thrombin, has been determined at 2.0 A resolution complexed with hirugen. The structure has been refined to a final R-value of 0.169 using 14,211 observed reflections in the resolution range 8.0-2.0 A. A total of 202 water molecules have also been located in the structure. Comparison with the hirugen-thrombin complex showed that, apart from the flexible beginning and terminal regions of the molecule, there are 4 polypeptide segments in pre2 differing in conformation from the active enzyme (Pro 186-Asp 194, Gly 216-Gly 223, Gly 142-Pro 152, and the Arg 15-Ile 16 cleavage region). The formation of the Ile 16-Asp 194 ion pair and the specificity pocket are characteristic of serine protease activation with the conformation of the catalytic triad being conserved. With the determination of isomorphous structures of hirugen-thrombin and D-Phe-Pro-Arg chloromethyl ketone (PPACK)-thrombin, the changes that occur in the active site that affect the kinetics of chromogenic substrate hydrolysis on binding to the fibrinogen recognition exosite have been determined. The backbone of the Ala 190-Gly 197 segment in the active site has an average RMS difference of 0.55 A between the 2 structures (about 3.7 sigma compared to the bulk structure). This segment has 2 type II beta-bends, the first bend showing the largest shift due to hirugen binding. Another important feature was the 2 different conformations of the side chain of Glu 192. The side chain extends to solvent in hirugen-thrombin, which is compatible with the binding of substrates having an acidic residue in the P3 position (protein-C, thrombin platelet receptor). In PPACK-thrombin, the side chain of Asp 189 and the segment Arg 221A-Gly 223 move to provide space for the inhibitor, whereas in hirugen-thrombin, the Ala 190-Gly 197 movement expands the active site region. Although 8 water molecules are expelled from the active site with PPACK binding, the inhibitor complex is resolvated with 5 other water molecules.

Investigating the applicability of Activity-based Quantum Mechanics in a few high school physics classrooms  

NSDL National Science Digital Library

Quantum physics is not traditionally introduced in high school physics courses because of the level of abstraction and mathematical formalism associated with the subject. As part of the Visual Quantum Mechanics project, activity-based instructional units have been developed that introduce quantum principles to students who have limited backgrounds in physics and mathematics. This study investigates the applicability of one unit, Solids & Light, that introduces quantum principles within the context of learning about light emitting diodes. An observation protocol, attitude surveys, and questionnaires were used to examine the implementation of materials and student-teacher interactions in various secondary physics classrooms. Aspects of Solids & Light including the use of hands-on activities, interactive computer programs, inexpensive materials, and the focus on conceptual understanding were very applicable in the various physics classrooms observed. Both teachers and students gave these instructional strategies favorable ratings in motivating students to make observations and to learn. These ratings were not significantly affected by gender or studentsâ attitudes towards physics or computers. Solids & Light was applicable in terms of content and teaching style for some teachers. However, a mismatch of teaching styles between some instructors and the unit posed some problems in determining applicability. Observations indicated that some instructors were not able to utilize the exploratory instructional strategy of Solids & Light. Thus, Solids & Light must include additional support necessary to make the instructor comfortable with the subject matter and pedagogical style. With these revisions, Solids & Light, will have all the key components to make its implementation in a high school physics classroom a successful one.

Changes in cerebellar activity and inter-hemispheric coherence accompany improved reading performance following Quadrato Motor Training.  

PubMed

Dyslexia is a multifactorial reading deficit that involves multiple brain systems. Among other theories, it has been suggested that cerebellar dysfunction may be involved in dyslexia. This theory has been supported by findings from anatomical and functional imaging. A possible rationale for cerebellar involvement in dyslexia could lie in the cerebellum's role as an oscillator, producing synchronized activity within neuronal networks including sensorimotor networks critical for reading. If these findings are causally related to dyslexia, a training regimen that enhances cerebellar oscillatory activity should improve reading performance. We examined the cognitive and neural effects of Quadrato Motor Training (QMT), a structured sensorimotor training program that involves sequencing of motor responses based on verbal commands. Twenty-two adult Hebrew readers (12 dyslexics and 10 controls) were recruited for the study. Using Magnetoencephalography (MEG), we measured changes in alpha power and coherence following QMT in a within-subject design. Reading performance was assessed pre- and post-training using a comprehensive battery of behavioral tests. Our results demonstrate improved performance on a speeded reading task following one month of intensive QMT in both the dyslexic and control groups. Dyslexic participants, but not controls, showed significant increase in cerebellar oscillatory alpha power following training. In addition, across both time points, inter-hemispheric alpha coherence was higher in the dyslexic group compared to the control group. In conclusion, the current findings suggest that the combination of motor and language training embedded in QMT increases cerebellar oscillatory activity in dyslexics and improves reading performance. These results support the hypothesis that the cerebellum plays a role in skilled reading, and begin to unravel the underlying mechanisms that mediate cerebellar contribution in cognitive and neuronal augmentation.

Diseases accompanying congenital hypothyroidism.  

PubMed

Abstract Introduction: Extrathyroidal abnormality incidence and especially the incidence of congenital cardiac disease are increased with congenital hypothyroidism. In this present study, it is aimed to evaluate patients who were being followed up for congenital hypothyroidism for accompanying diseases, and to compare impacts of accompanying diseases on prognosis under the light of published articles in the literature. Material and methods: A total of 400 cases which were diagnosed with, treated and followed up for congenital hypothyroidism in our clinic were retrospectively evaluated. Cases with complaining symptoms and without any complaints, but were diagnosed with hypothyroidism as the result of screening tests were enrolled in the study. Results: Of 400 subjects included due to congenital hypothyroidism, 186 (46.5%) were girls and 214 (53.5%) were boys. Accompanying diseases were diagnosed in 113 cases (28.2%). Accompanying diseases according to the frequency order were congenital cardiac disease (n=32, 8.0%), Down syndrome (n=25, 6.3%), inguinal hernia (n=21, 5.30%), undescended testicles (n=8, 2.0%), GH deficiency (n=4, 1.0%), and some other systemic diseases (n=23, 5.8%). In cases accompanied by congenital cardiac diseases, ventricular septal defect (n=10), atrial septal defect (n=9), pulmonary stenosis (n=7), patent ductus arteriosis (n=7), and aortic coarctation (n=3) were detected. Conclusion: In this present study, it was defined that approximately one third of patients with congenital hypothyroidism had an accompanying disease, and cardiac diseases were the most common problem. It is concluded that evaluation of congenital hypothyroidism cases for accompanying diseases, detailed cardiological examination being in the first order, is important for prognosis. PMID:24353135

Pneumopathogenicity in mice of a Sendai virus mutant, TSrev-58, is accompanied by in vitro activation with trypsin.  

PubMed Central

The pneumopathogenicity of a trypsin-sensitive revertant of Sendai virus, TSrev-58, which was derived from a trypsin-resistant mutant, TR-5, was examined in mice. In comparison with TR-5, the revertant had a single amino acid substitution at residue 116 (Ile----Arg) on F protein, which was the cleavage site, and had the same trypsin sensitivity as the wild-type virus. However, TSrev-58 still had a single amino acid difference from the wild-type virus at residue 109 (Asn----Asp) (M. Itoh, H. Shibuta, and M. Homma, J. Gen. Virol. 68:2939-2943, 1987). Nevertheless, the present study revealed that TSrev-58 had the same pneumopathogenicity in mice as the wild-type virus. This result indicates that the activating protease of Sendai virus present in the lungs of mice is quite similar to trypsin and also that the in vitro trypsin sensitivity of Sendai virus can be a good marker of pneumopathogenicity in mice.

Eliciting Metacognitive Experiences and Reflection in a Year 11 Chemistry Classroom: An Activity Theory Perspective  

NASA Astrophysics Data System (ADS)

Concerns regarding students' learning and reasoning in chemistry classrooms are well documented. Students' reasoning in chemistry should be characterized by conscious consideration of chemical phenomenon from laboratory work at macroscopic, molecular/sub-micro and symbolic levels. Further, students should develop metacognition in relation to such ways of reasoning about chemistry phenomena. Classroom change eliciting metacognitive experiences and metacognitive reflection is necessary to shift entrenched views of teaching and learning in students. In this study, Activity Theory is used as the framework for interpreting changes to the rules/customs and tools of the activity systems of two different classes of students taught by the same teacher, Frances, who was teaching chemical equilibrium to those classes in consecutive years. An interpretive methodology involving multiple data sources was employed. Frances explicitly changed her pedagogy in the second year to direct students attention to increasingly consider chemical phenomena at the molecular/sub-micro level. Additionally, she asked students not to use the textbook until toward the end of the equilibrium unit and sought to engage them in using their prior knowledge of chemistry to understand their observations from experiments. Frances' changed pedagogy elicited metacognitive experiences and reflection in students and challenged them to reconsider their metacognitive beliefs about learning chemistry and how it might be achieved. While teacher change is essential for science education reform, students are not passive players in change efforts and they need to be convinced of the viability of teacher pedagogical change in the context of their goals, intentions, and beliefs.

Increased Resorptive Activity and Accompanying Morphological Alterations in Osteoclasts Derived From the Oim/Oim Mouse Model of Osteogenesis Imperfecta  

PubMed Central

The current study addresses whether alterations in osteoclasts (OCs) derived from oim/oim mice, an established model of moderate-to-severe OI, are present. Bone marrow cells from oim/oim and wildtype (+/+) mice were cultured on bone slices in the presence of MCSF and RANKL and evaluated at days 0, 1, 2, 4, and 7. OCs were identified by tartrate-resistant acid phosphatase (TRAP) staining, and bone slice resorption pits were analyzed by reflection microscopy. Flow cytometry was used to examine CD51 (integrin ?V) and CD61 (integrin ?3) markers. Confocal microscopy was used to assess changes in OC morphology and resorption. There was no difference between the OC precursors of the two genotypes in expression of CD51 and CD61 markers. At day 2, the bone slices seeded with oim/oim cells had a greater percentage of mononuclear cells associated with resorption pits compared to +/+ bone slices. At day 4, the diameter and area of oim/oim OCs were larger compared to the +/+ OCs, and the number of nuclei per OC was also greater for the oim/oim group. At day 7, the oim/oim OCs contained more F-actin rings compared to the +/+ OCs, and the number of OCs in the oim/oim group was greater compared to the +/+ group. The resorbed area of bone slices for the oim/oim group was also greater compared to the +/+ group at day 7. In conclusion, oim/oim mononuclear resorbing cells and OCs showed cellular changes and greater resorptive activity compared to +/+ cells, features that likely contribute to dysregulated bone remodeling in OI.

Activity Structures and the Unfolding of Problem-Solving Actions in High-School Chemistry Classrooms  

NASA Astrophysics Data System (ADS)

In this paper, we argue for a more systematic approach for studying the relationship between classroom practices and scientific practices—an approach that will likely better support the systemic reforms being promoted in the Next Generation Science Standards in the USA and similar efforts in other countries. One component of that approach is looking at how the nature of the activity structure may influence the relative alignment between classroom and scientific practices. To that end, we build on previously published research related to the practices utilized by five high-school chemistry teachers as they enacted problem-solving activities in which students were likely to generate proposals that were not aligned with normative scientific understandings. In that prior work, our analysis had emphasized micro-level features of the talk interactions and how they related to the way students' ideas were explored; in the current paper, the analysis zooms out to consider the macro-level nature of the enactments associated with the activity structure of each lesson examined. Our data show that there were two general patterns to the activity structure across the 14 lessons scrutinized, and that each pattern had associated with it a constellation of features that impinged on the way the problem space was navigated. A key finding is that both activity structures (the expansive and the open) had features that aligned with scientific practices espoused in the Next Generation Science Standards—and both had features that were not aligned with those practices. We discuss the nature of these two structures, evidence of the relationship of each structure to key features of how the lessons unfolded, and the implications of these findings for both future research and the training of teachers.

Using analogy role-play activity in an undergraduate biology classroom to show central dogma revision.  

PubMed

For the study of biology in an undergraduate classroom, a classroom exercise was developed: an analogy role-play to learn mechanisms of gene transcription and protein translation (central dogma). To develop the central dogma role-play exercise, we made DNA and mRNA using paper sheets, tRNA using a wire dress hanger, and amino acids using Lego® blocks (Lego System A/S, Denmark). Students were studying in the course of mathematics, physics, or chemistry, so biology was not among their usual studies. In this exercise, students perform the central dogma role-play and respectively act out nuclear matrix proteins, a transcription factor, an RNA polymerase II, an mRNA transport protein, nuclear pore proteins, a large ribosomal subunit, a small ribosomal subunit, and several amino-acyl tRNA synthetases. Questionnaire results obtained after the activity show that this central dogma role-play analogy holds student interest in the practical molecular biological processes of transcription and translation. © 2014 by The International Union of Biochemistry and Molecular Biology, 42(4):351-356, 2014.

Local activation of Rap1 contributes to directional vascular endothelial cell migration accompanied by extension of microtubules on which RAPL, a Rap1-associating molecule, localizes.  

PubMed

Endothelial cell migration is promoted by chemoattractants and is accompanied with microtubule extension toward the leading edge. Cytoskeletal microtubules polarize to function as rails for delivering a variety of molecules by motor proteins during cell migration. It remains, however, unclear how directional migration with polarized extension of microtubules is regulated. Here we report that Rap1 controls the migration of vascular endothelial cells. We found that Rap1-associating molecule, RAPL, which belongs to the Ras association domain family (Rassf), localized on microtubules and that activated Rap1 induced dissociation of RAPL from microtubules. A Rap1 activation-monitoring probe based on the fluorescence resonance energy transfer enabled us to demonstrate that local Rap1 activation occurs at the leading edge of the cells under the two types of cell migration, chemotaxis and wound healing. Time lapse imaging of microtubules marked by enhanced green fluorescent protein-RAPL showed the directional growth of microtubules toward the leading edge of the migrating cells. Using adenovirus, inactivation of Rap1 by expression of rap1GAPII inhibited wound healing. In addition, disconnection of Rap1 and RAPL by expression of a RAPL mutant also perturbed wound healing. Collectively, the locally activated Rap1 and its association with RAPL controls the directional migration of vascular endothelial cells. PMID:15569673

Designing and Evaluating Classroom Activities Using Remotely Operated Microbeam Instruments: Some Preliminary Results  

NASA Astrophysics Data System (ADS)

Using analytical instruments in undergraduate courses is a longstanding method for exposing students to aspects of the research process. A range of instruments (XRD, AA/ICP-OES, IC, ICP-MS; MCS, GPR etc.) have been used in geoscience courses, often with the ancillary outcome of facilitating undergraduate research projects. These activities generally involve instruments available in-house; are usually restricted to "workhorse" instruments that can tolerate use by inexperienced student users; and are focused on comparatively basic analytical tools, as the output data are often more amenable to course content and direction, but also because such tools are viewed as more appropriate to the undergraduate experience. Despite abundant research uses in the geosciences, microbeam technologies (i.e., Scanning Electron Microscope (SEM) and Electron Microprobe (EPMA)) have not been as heavily utilized in the classroom, due to the higher cost of these instruments and the relative delicacy of the hardware, which can involve multiple integrated spectrometers and imaging systems. SEM has been used on occasion as a classroom tool, at times as a lower cost stand-in for EMPA (i.e., Beane 2004), and for its high-resolution imaging capabilities. Remote instrument operation (Pratap et al. 2004) offers a means to bring advanced microbeam instruments into the classroom. We are using the remotely operable SEM and EPMA instruments at the Florida Center for Analytical Electron Microscopy (FCAEM, at FIU in Miami, FL) at the University of South Florida in Tampa, FL in introductory-level and upper level courses. Students receive instruction in microbeam analysis and the specifics of the instrument they are to use (SEM or EPMA). Instrument operation sessions occur in class, examining samples prepared by student teams as part of class projects. Assessment of effectiveness includes student impression surveys, and content-specific testing related to the activities. Early results indicate student excitement at collecting their own data, but discomfort with instrument use, due to lack of experience. To address this issue, I have added a whole-class interactive exercise on the instrument, followed by mentored data collection periods for each student team.

Geometric Reasoning in an Active-Engagement Upper-Division E&M Classroom  

NASA Astrophysics Data System (ADS)

A combination of theoretical perspectives is used to create a rich description of student reasoning when facing a highly-geometric electricity and magnetism problem in an upper-division active-engagement physics classroom at Oregon State University. Geometric reasoning as students encounter problem situations ranging from familiar to novel is described using van Zee and Manogue's (2010) ethnography of communication. Bing's (2008) epistemic framing model is used to illuminate how students are framing what they are doing and whether or not they see the problem as geometric. Kuo, Hull, Gupta, and Elby's (2010) blending model and Krutetskii's (1976) model of harmonic reasoning are used to illuminate ways students show problem-solving expertise. Sayer and Wittmann's (2008) model is used to show how resource plasticity impacts students' geometric reasoning and the degree to which students accept incorrect results.

Resveratrol enhances radiosensitivity of human non-small cell lung cancer NCI-H838 cells accompanied by inhibition of nuclear factor-kappa B activation.  

PubMed

Resveratrol, a polyphenol in red wine, possesses many pharmacological activities including cardioprotection, chemoprevention, anti-tumor effects, and nuclear factor-kappa B (NF-kappaB) inactivation. The present study was designed to evaluate the effects and possible mechanism of resveratrol in enhancing radiosensitivity of lung cancer cells. Human non-small cell lung cancer NCI-H838 cells were irradiated with or without resveratrol pretreatment. The surviving fraction and sensitizer enhancement ratio (SER) were estimated by using a colony formation assay and linear-quadratic model. The cell-cycle distribution was evaluated by using propidium iodide staining and flow cytometry. An ELISA-based assay with immobilized oligonucleotide was performed to assess the DNA binding activity of NF-kappaB. Resveratrol had no direct growth-inhibitory effect on NCI-H838 cells treated for 24 hours with doses up to 25 microM. Pretreatment with resveratrol significantly enhanced cell killing by radiation, with an SER up to 2.2. Radiation activated NF-kappaB, an effect reversed by resveratrol pretreatment. Resveratrol resulted in a decrease of cells in the G0/G1 phase and an increase in the S phase. Our results demonstrate that resveratrol enhances the radiosensitivity of NCI-H838 cells accompanied by NF-kappaB inhibition and S-phase arrest. PMID:16394628

T Cell Activation and Proinflammatory Cytokine Production in Clinically Cured Tuberculosis Are Time-Dependent and Accompanied by Upregulation of IL-10  

PubMed Central

Background Th1 cytokines are essential for the control of M. tuberculosis infection. The role of IL-10 in tuberculosis is controversial and there is an increasing body of evidence suggesting that the relationship between Th1 cytokines and IL-10 is not as antagonistic as it was first believed, and that these cytokines may complement each other in infectious diseases. Methods The present study evaluated the activating capacity of CD4+ and CD8+ T cell repertoire in response to antigen stimulation through the expression of CD69 using Flow Cytometry, as well as the functionality of PBMCs by determining the cytokine profile in patients with active tuberculosis and in clinically cured patients after in vitro stimulation using ELISA. Treated patients were subdivided according to time after clinical cure (<12 months or >12 months post-treatment). Results We observed that T cell activation was higher in TB-treated patients, especially CD8+ T cell activation in TB-Treated >1 year. Th1 cytokines were significantly higher in TB-Treated, and the levels of IFN-? and TNF-? increased continuously after clinical cure. Moreover, IL-10 production was significantly higher in cured patients and it was also enhanced in cured patients over time after treatment. Th17, Th2 and Th22 cytokines showed no statistically significant differences between Healthy Donors, Active-TB and TB-Treated. Conclusions This study describes a scenario in which potentiation of CD4+ and CD8+ T cell activation and increased Th1 cytokine production are associated with the clinical cure of tuberculosis in the absence of significant changes in Th2 cytokine production and is accompanied by increased production of IL-10. In contrast to other infections with intracellular microorganisms, this response occurs later after the end of treatment.

Modulation of pineal activity during the 23rd sunspot cycle: melatonin rise during the ascending phase of the cycle is accompanied by an increase of the sympathetic tone.  

PubMed

In two groups of female CD-rats nocturnal urine (19-23 h, 23-3 h, 3-7 h) was collected at monthly intervals over 658 days (I: 1997-1999) and 494 days (II: 1999-2000) coinciding with the ascending limb (1996-2000) of the 23rd sunspot cycle (1996-2008). The excretion of 6-sulfatoxymelatonin (aMT6s: I, II) was determined as well as the ratio of noradrenaline/adrenaline (NA/A: I) reflecting the activity of the sympathetic nervous system. AMT6s was higher in II than I (19-7 h: +24%; P < 0.001; 23-3 h: +30% and 3-7 h: +17%, P < 0.001), and progressively increased (19-23 h) showing linear regressions (1: R = +0.737, P = 0.003; II: R = +0.633, 0.008) which correlated (I) with the Planetary Index (Ap: R = +0.598, P = 0.020), an established estimate of geomagnetic disturbances due to solar activity. NA/A rose at all intervals (I: 46-143%) correlating with Ap (R = +0.554-0.768; P = 0.0399-0.0013). These results indicate that melatonin secretion rises as solar activity increases during the ascending limb of a sunspot cycle accompanied by growing geomagnetic disturbances (Ap) which elevate the sympathetic tone and thus affect the pineal gland, initially stimulating the activity of arylalkylamine N-acetyltransferase and subsequently fostering the expression of N-acetylserotonin O-methyltransferase (rate-limiting enzyme for melatonin biosynthesis) if Ap increases further. The potential (patho) physiological significance of these findings is discussed and the need for a systematic continuation of such studies is emphasized. PMID:24851406

Long-Term Vision and Non-Vision Dominant Behavioral Deficits in the 2-VO Rats Are Accompanied by Time and Regional Glial Activation in the White Matter  

PubMed Central

The permanent occlusion of common carotid arteries (2-VO) in rats has been shown to induce progressive and long-lasting deficits in cognitive performance, however, whether these aberrant behaviors are attributed to visual dysfunction or cognitive impairment and what are the underlying mechanisms, remain controversial. In the present study, vision dominant (Morris water maze) and non-vision dominant (voice-cued fear conditioning) behavioral tests were assigned to comprehensively evaluate the influence of 2-VO lesion on cognitive behaviors. In the Morris water maze test, escape latencies of 2-VO rats were markedly increased in both hidden and unfixed visible platform tasks, which were accompanied by severe retinal damage. In the voice-cued fear conditioning test, significant reduction in the percentage of freezing behavior was observed at 60 days after 2-VO lesion. Chronic lesion by 2-VO failed to cause noticeable changes in the grey matter, as indicated by intact hippocampal and prefrontal cortical structures, sustained synaptic protein levels and glial cell numbers. In contrast, aberrant arrangement of myelinated axons was observed in the optic tract, but not in the corpus callosum and inner capsule of 2-VO rats. Concurrently, marked astrocyte proliferation and microglia activation in the optic tract occurred at 3 days after 2-VO lesion, and continued for up to 60 days. Differently, robust glial activation was observed in the corpus callosum at 3 days after 2-VO surgery, and then gradually returned to the baseline level at 14 and 60 days. Our study reported for the first time about the effect of 2-VO on the long-term cognitive impairment in the non-vision dominant fear conditioning test, which may be more applicable than the Morris water maze test for assessing 2-VO associated cognitive function. The time and region specific glial activation in the white matter may relate to retinal impairment, even behavioral deficits, in the setting of chronic cerebral hypoperfusion.

Effects of sensory education based on classroom activities for lower grade school children.  

PubMed

This study is to verify the effects of sensory education based on classroom activities for 2(nd) and 3(rd) grade children. The hypothesis is that children who participated in sensory education would demonstrate positive changes in eating behaviors through sensory experiences. The sensory education program consists of 12 lessons. Twenty-six children were being recruited from one school in Changwon, Korea. Two control groups, one of which was the same age as the educated group and the other group of sixth graders, were selected by random sampling from the same school. Children answered a self-administered questionnaire. The parents (n = 20) of the children who participated in the program, took part in evaluating the program through self-administered questionnaires after the program ended. The questionnaire contained variables of general characteristics, education satisfaction, nutrition knowledge, eating attitude and behavior concerning unfamiliar foods. The score of nutrition knowledge was improved in educated children (P < 0.05). Food neophobia score towards unfamiliar foods (P < 0.05) was increased in educated children, but there are no changes in eating behaviors in all groups towards unfamiliar foods. In conclusion, sensory education is useful for having a positive eating attitude among children. Its consistent implementation could lead to healthier and well-balanced eating behaviors for children.

Effects of sensory education based on classroom activities for lower grade school children  

PubMed Central

This study is to verify the effects of sensory education based on classroom activities for 2nd and 3rd grade children. The hypothesis is that children who participated in sensory education would demonstrate positive changes in eating behaviors through sensory experiences. The sensory education program consists of 12 lessons. Twenty-six children were being recruited from one school in Changwon, Korea. Two control groups, one of which was the same age as the educated group and the other group of sixth graders, were selected by random sampling from the same school. Children answered a self-administered questionnaire. The parents (n = 20) of the children who participated in the program, took part in evaluating the program through self-administered questionnaires after the program ended. The questionnaire contained variables of general characteristics, education satisfaction, nutrition knowledge, eating attitude and behavior concerning unfamiliar foods. The score of nutrition knowledge was improved in educated children (P < 0.05). Food neophobia score towards unfamiliar foods (P < 0.05) was increased in educated children, but there are no changes in eating behaviors in all groups towards unfamiliar foods. In conclusion, sensory education is useful for having a positive eating attitude among children. Its consistent implementation could lead to healthier and well-balanced eating behaviors for children.

Increasing active student participation in the classroom through the use of ``flash cards''  

NASA Astrophysics Data System (ADS)

Large lecture classes make it difficult to maintain high levels of student-faculty interaction; in these classes, students traditionally play a relatively passive role. We have been making use of techniques for increasing active student participation in the lecture classroom, and for raising the level of interaction between students and instructors. A central element in these methods is the use of ``flash cards'' which allow students to instantaneously indicate to the instructor their responses to multiple-choice questions. Students use 8.5×11 inch flash cards, labeled ``A,'' ``B,'' ``C,'' ``D,'' ``E,'' and ``F'' to signal their responses to the instructor. Flash-card questions emphasize qualitative and proportional reasoning, solution strategies for problems, order of magnitude estimates, etc. Responses provide feedback to the instructor on student misconceptions, and pace of student understanding. Here we show an example of how we break down a conventional problem into conceptual elements-a so-called ``problem dissection''-which can then be formed into flash-card questions.

Characterization of very-long-period seismicity accompanying summit activity at K?lauea Volcano, Hawai'i: 2007-2013  

NASA Astrophysics Data System (ADS)

Eruptive activity returned to the summit region of K?lauea Volcano, Hawai'i with the formation of the “Overlook crater” within the Halema'uma'u Crater in March 2008. The new crater continued to grow through episodic collapse of the crater walls and as of late 2013 had grown into an approximately elliptical opening with dimensions of ~ 160 × 215 m extending to a depth of ~ 200 m. Occasional weak explosive events and a persistent gas plume continued to occur through 2013. Lava was first observed in the new crater in September 2008, and through 2009 the lava level remained deep in the crater and was only occasionally observed. Since early 2010 a lava lake with fluctuating level within the Overlook crater has been nearly continuously present, and has reached to within 22 m of the Overlook crater rim. Volcanic activity at K?lauea Volcano is episodic at all time scales and the characterization of very-long-period seismicity in the band 2-100 s for the years 2007-2013 illuminates a portion of this broad spectrum of volcanic behavior. Three types of very-long-period events have been observed over this time and each is associated with distinct processes. Type 1 events are associated with vigorous degassing and occurred primarily between 2007 and 2009. Type 2 events are associated with rockfalls onto the lava lake and occurred primarily after early 2010. Both of these event types are induced by pressure and momentum changes at the top of the magma column that are transmitted downward to a source centroid ~ 1 km below the northeast corner of the Halema'uma'u Crater where the energy couples to the solid Earth at a geometrical discontinuity in the underlying dike system. Type 3 events are not related to surficial phenomena but are associated with transients in mass transfer that occur within the dike system. Very-long-period tremor has also accompanied the return of eruptive activity, with increasing amplitude associated with hours- to months-long changes in gas emission rates and summit deformation.

Classroom Activities: Simple Strategies to Incorporate Student-Centered Activities within Undergraduate Science Lectures  

PubMed Central

The traditional science lecture, where an instructor delivers a carefully crafted monolog to a large audience of students who passively receive the information, has been a popular mode of instruction for centuries. Recent evidence on the science of teaching and learning indicates that learner-centered, active teaching strategies can be more effective learning tools than traditional lectures. Yet most colleges and universities retain lectures as their central instructional method. This article highlights several simple collaborative teaching techniques that can be readily deployed within traditional lecture frameworks to promote active learning. Specifically, this article briefly introduces the techniques of: reader’s theatre, think-pair-share, roundtable, jigsaw, in-class quizzes, and minute papers. Each technique is broadly applicable well beyond neuroscience courses and easily modifiable to serve an instructor’s specific pedagogical goals. The benefits of each technique are described along with specific examples of how each technique might be deployed within a traditional lecture to create more active learning experiences.

Students' development of models of magnetic materials, patterns of group activity, and social norms in a physics classroom  

NASA Astrophysics Data System (ADS)

This dissertation is a study of students' model development processes in a physical science course for preservice elementary teachers. It details the models of magnetic materials developed and used by students during a unit on static electricity and magnetism. In this inquiry-based course, the class developed and formally accepted a model, in the form of diagrams and descriptions, that is very similar to the accepted magnetic domains model. They did this without textbooks or lectures on magnetism. Before adopting this model, however, most groups in the class temporarily used models involving opposite charges at the two ends of magnetized nails. How did the students do it? The explanation involves detailed study of the groups' interactions and use of structure in the classroom environment. This dissertation uses two theoretical frameworks to analyze interactions. It applies Yackel and Cobb's (1996) concepts of classroom social norms to characterize aspects of the classroom participation structure which affected groups' construction and declaration of models. It also applies distributed cognition ideas to analyze the sense-making conversations that small groups had when constructing group responses. This research found that conversations in one small group could be characterized into sixteen categories. Important categories included "extending ideas" which involved gradual deepening and elaboration of the group's understanding of their model(s), and "joint typing", an interactive process by which group members collaborated on typed statements or group diagrams and simultaneously developed common language for communicating their ideas to each other. Some of these categories of activity were closely connected to computer use. Also, four classroom norms are described. One small group social classroom norm involved group members developing a "common ground" consisting of agreed-upon group statements. Three sociophysics norms which characterize the whole class interactions as well as those of the small group involved a distinction between generalizations of phenomena and theoretical statements, class criteria for accepting evidence, and the obligation for each group to have a model of magnetic materials that they could support with acceptable evidence.

Classroom response systems: What do they add to an active learning environment?  

NASA Astrophysics Data System (ADS)

This study investigated the impact of completely anonymous Classroom Response System (CRS) use on learning outcomes and student attitudes in a large university physical science course for pre-service teachers. As students were expected to have read the textbook prior to class, class time was devoted primarily to conceptual introductions followed by small group discussions of qualitative questions. In the treatment condition, each group provided a single response anonymously using the CRS. The control group responded individually and publicly by show of hands. Responses formed the basis for further discussion in both cases. Anonymity of responses in the control condition was expected to enhance participation and to provide more reliable formative assessment for the instructor, thus enhancing subsequent instruction and learning. The overwhelmingly female study population comprised two course sections with the same instructor. The sections reversed treatment and control group roles for units on Newtonian mechanics and thermodynamics. Students took pre- and posttests for each unit, completed Response System Surveys once and the VASS twice, and submitted weekly mini-reflections and one metareflection. These were analyzed for evidence of attitudes toward science and learning. Whole-class discussions were video-recorded and analyzed for evidence of participation and use of student responses for "just-in-time" teaching. Although CRS use did not improve learning outcomes over the control as measured by pre and posttests, it improved participation, as reflected in the video record and as self-reported by students in reflections, while it was in use. When they were using the CRS, students also indicated greater interest in learning for understanding, as opposed to preferring authoritarian delivery of information by the instructor and opportunities for procedural drills. A framework for classroom interactions emerged. This "C3" framework comprised three dimensions interacting on and through classroom conditions: concerns (performance goals to mastery goals), centeredness (teacher-centered to learner-centered), and control of discourse (traditional lecture to interactive dialogue). These apply to both instructors and students. In previous work, CRS use in classrooms was determined by instructors' positions on these three dimensions. Here, students shifted their centeredness and concerns based on how much the instructor shared the control of classroom discourse.

Short-term high-fat-and-fructose feeding produces insulin signaling alterations accompanied by neurite and synaptic reduction and astroglial activation in the rat hippocampus.  

PubMed

Chronic consumption of high-fat-and-fructose diets (HFFD) is associated with the development of insulin resistance (InsRes) and obesity. Systemic insulin resistance resulting from long-term HFFD feeding has detrimental consequences on cognitive performance, neurogenesis, and long-term potentiation establishment, accompanied by neuronal alterations in the hippocampus. However, diet-induced hippocampal InsRes has not been reported. Therefore, we investigated whether short-term HFFD feeding produced hippocampal insulin signaling alterations associated with neuronal changes in the hippocampus. Rats were fed with a control diet or an HFFD consisting of 10% lard supplemented chow and 20% high-fructose syrup in the drinking water. Our results show that 7 days of HFFD feeding induce obesity and InsRes, associated with the following alterations in the hippocampus: (1) a decreased insulin signaling; (2) a decreased hippocampal weight; (3) a reduction in dendritic arborization in CA1 and microtubule-associated protein 2 (MAP-2) levels; (4) a decreased dendritic spine number in CA1 and synaptophysin content, along with an increase in tau phosphorylation; and finally, (5) an increase in reactive astrocyte associated with microglial changes. To our knowledge, this is the first report addressing hippocampal insulin signaling, as well as morphologic, structural, and functional modifications due to short-term HFFD feeding in the rat.

Distinct Compartmentalization of NF-?B Activity in Crypt and Crypt-Denuded Lamina Propria Precedes and Accompanies Hyperplasia and/or Colitis following Bacterial Infection  

PubMed Central

Citrobacter rodentium induces transmissible murine colonic hyperplasia (TMCH) and variable degrees of inflammation and necrosis depending upon the genetic background. Utilizing C. rodentium-induced TMCH in C3H/HeNHsd inbred mice, we observed significant crypt hyperplasia on days 3 and 7 preceding active colitis. NF-?B activity in the crypt-denuded lamina propria (CLP) increased within 24 h postinfection, followed by its activation in the crypts at day 3, which peaked by day 7. Increases in interleukin-?1 (IL-1?), IL-12(p40), and macrophage inflammatory protein 1? (MIP-1?) paralleled NF-?B activation, while increases in IL-1?/?, IL-6/IL-12(p40)/granulocyte colony-stimulating factor (G-CSF)/keratinocyte-derived chemokine (KC)/monocyte chemotactic protein 1 (MCP-1), and MIP-1? followed NF-?B activation leading to significant recruitment of neutrophils to the colonic mucosa and increased colonic myeloperoxidase (MPO) activity. Phosphorylation of the crypt cellular and nuclear p65 subunit at serines 276 and 536 led to functional NF-?B activation that facilitated expression of its downstream target, CXCL-1/KC, during TMCH. Distinct compartmentalization of phosphorylated extracellular signal-regulated kinase 1 and 2 ([ERK1/2] Thr180/Tyr182) and p38 (Thr202/Tyr204) in the CLP preceded increases in the crypts. Inhibition of ERK1/2 and p38 suppressed NF-?B activity in both crypts and the CLP. Dietary administration of 6% pectin or 4% curcumin in C. rodentium-infected mice also inhibited NF-?B activity and blocked CD3, F4/80, IL-1?/?, G-CSF/MCP-1/KC, and MPO activity in the CLP while not affecting NF-?B activity in the crypts. Thus, distinct compartmentalization of NF-?B activity in the crypts and the CLP regulates crypt hyperplasia and/or colitis, and dietary intervention may be a novel strategy to modulate NF-?B-dependent protective immunity to facilitate crypt regeneration following C. rodentium-induced pathogenesis.

Apoplastic Ca2+ concentration controls membrane permeability, cell wall stabilization and cell integrity; however, little is known about its role in thermotolerance in plants. Here, we report that the acquired thermotolerance of etiolated rice seedlings (Oryza sativa) was abolished by an exogenously supplied Ca2+ chelator, EGTA, related to increased cellular content leakage during heat shock (HS) treatment. Thermotolerance was restored by the addition of Ca2+ during EGTA incubation. Pectin methylesterase (EC 3.1.1.11), a cell-wall remodeling enzyme, was activated in response to HS and its elevated activity was related to the recovery of the HS-released Ca2+ concentration. EGTA interfered with the capability of HS to increase oscillation of [Ca2+]cyt content. We assume that heat-activated PME activity is involved in cell-wall localized Ca2+. The removal of apoplastic Ca2+ might participate in HS signaling to induce HS protein expression and cell-wall remodeling to retain plasma membrane integrity, prevent cellular content leakage and confer thermoprotection.

LPS-induced IL8 activation in human intestinal epithelial cells is accompanied by specific histone H3 acetylation and methylation changes  

Microsoft Academic Search

BACKGROUND: The release of LPS by bacteria stimulates both immune and specific epithelial cell types to release inflammatory mediators. It is known that LPS induces the release of IL-8 by intestinal mucosal cells. Because it is now emerging that bacteria may induce alteration of epigenetic patterns in host cells, we have investigated whether LPS-induced IL-8 activation in human intestinal epithelial

Visualization of Structural Changes Accompanying Activation of N-Methyl-d-aspartate (NMDA) Receptors Using Fast-scan Atomic Force Microscopy Imaging*  

PubMed Central

NMDA receptors are widely expressed in the central nervous system and play a major role in excitatory synaptic transmission and plasticity. Here, we used atomic force microscopy (AFM) imaging to visualize activation-induced structural changes in the GluN1/GluN2A NMDA receptor reconstituted into a lipid bilayer. In the absence of agonist, AFM imaging revealed two populations of particles with heights above the bilayer surface of 8.6 and 3.4 nm. The taller, but not the shorter, particles could be specifically decorated by an anti-GluN1 antibody, which recognizes the S2 segment of the agonist-binding domain, indicating that the two populations represent the extracellular and intracellular regions of the receptor, respectively. In the presence of glycine and glutamate, there was a reduction in the height of the extracellular region to 7.3 nm. In contrast, the height of the intracellular domain was unaffected. Fast-scan AFM imaging combined with UV photolysis of caged glutamate permitted the detection of a rapid reduction in the height of individual NMDA receptors. The reduction in height did not occur in the absence of the co-agonist glycine or in the presence of the selective NMDA receptor antagonist d(?)-2-amino-5-phosphonopentanoic acid, indicating that the observed structural change was caused by receptor activation. These results represent the first demonstration of an activation-induced effect on the structure of the NMDA receptor at the single-molecule level. A change in receptor size following activation could have important functional implications, in particular by affecting interactions between the NMDA receptor and its extracellular synaptic partners.

Anti-influenza virus effects of both live and non-live Lactobacillus acidophilus L-92 accompanied by the activation of innate immunity.  

PubMed

The antiviral effects of both a live and non-live Lactobacillus acidophilus strain L-92 (L-92) were investigated by oral administration (10 mg/mouse per d) daily for 21 d in a mouse model infected intranasally with influenza virus (H1N1). Virus titres in the lung of mice administered either live or non-live L-92 cells daily for 15 d were repressed 6 d after virus infection compared with the control group. Natural killer (NK) activity in the orally administered non-live L-92 group was higher compared with that of the control group before virus infection and on day 6. In contrast, NK activity in the live L-92 group compared with the control group was not significantly changed on both days, but was significantly higher on day 1. In contrast, live L-92 showed a greater repression of virus proliferation compared with non-live L-92, 6 d after the infection. Live L-92 decreased the number of neutrophils in the lung and suppressed lung weight, leading to the consequent deterioration of consolidation scores of the lung. These results indicated that pretreatment of live or non-live L-92 cells had protective effects against influenza virus infection. Among the measured cytokines and chemokines, eotaxin, macrophage colony-stimulating factor, IL-1b, RANTES (regulated on activation, normal T cell expressed and secreted) and interferon-a were significantly increased in the lung: IL-17 was significantly increased in Peyer’s patch of the live L-92 group compared with the control group. A mechanistic study suggested that the enhancement of NK activity in the lung caused by stimulating various antiviral cytokines and chemokines after the oral administration of L-92 cells might be important in protecting against virus infection.

Distinct roles of methamphetamine in modulating spatial memory consolidation, retrieval, reconsolidation and the accompanying changes of ERK and CREB activation in hippocampus and prefrontal cortex.  

PubMed

Drugs of abuse modulated learning and memory in humans yet the underlying mechanism remained unclear. The extracellular signal-regulated kinase (ERK) and the transcription factor cAMP response element-binding protein (CREB) were involved in neuroplastic changes associated with learning and memory. In the current study, we used a Morris water maze to examine the effect of methamphetamine (METH) on different processes of spatial memory in mice. We then investigated the status of ERK and CREB in the hippocampus and prefrontal cortex (PFC). We found that 1.0 mg/kg dose of METH facilitated spatial memory consolidation when it was injected immediately after the last learning trial. In contrast, the same dose of METH had no effect on spatial memory retrieval when it was injected 30 min before the test. Furthermore, 1.0 mg/kg dose of METH injected immediately after retrieval had no effect on spatial memory reconsolidation. Activation of both ERK and CREB in the hippocampus was found following memory consolidation but not after retrieval or reconsolidation in METH-treated mouse groups. In contrast, activation of both ERK and CREB in the PFC was found following memory retrieval but not other processes in METH-treated mouse groups. These results suggested that METH facilitated spatial memory consolidation but not retrieval or reconsolidation. Moreover, activation of the ERK and CREB signaling pathway in the hippocampus might be involved in METH-induced spatial memory changes. PMID:23159329

Comets in the Classroom  

NASA Astrophysics Data System (ADS)

We proposed a partnership with the Rochester (New York) City School District to enhance their space science curriculum through teacher training seminars designed to increase teachers' knowledge of astronomy. On 1 April 1998, we facilitated the third grade science in-service program. We presented background science information on the Moon and demonstrated hands-on activities that teachers could transfer to their classrooms. During the 1998-99 school year, we visited several middle schools within the school district to facilitate the ``Comet in the Classroom'' program with sixth grade teachers. ``Comets in the Classroom'' presents background knowledge about comets and explains several hands-on activities regarding comets and their travels through the inner solar system. This work is funded through NASA's Initiative to Develop Education through Astronomy and Space Sciences (IDEAS) program.

Targeting EGFR activity in blood vessels is sufficient to inhibit tumor growth and is accompanied by an increase in VEGFR-2 dependence in tumor endothelial cells.  

PubMed

Epidermal growth factor receptor (EGFR) targeting agents such as kinase inhibitors reduce tumor growth and progression. We have previously reported that EGFR is not only expressed by the tumor cells but by the tumor endothelial cells (EC) as well (Amin, D. N., Hida, K., Bielenberg, D. R., Klagsbrun, M., 2006. Tumor endothelial cells express epidermal growth factor receptor (EGFR) but not ErbB3 and are responsive to EGF and to EGFR kinase inhibitors. Cancer Res. 66, 2173-80). Thus, targeting tumor blood vessel EGFR may be a viable strategy for tumor growth inhibition. We describe here a melanoma xenograft model where the tumor cells express very little or no EGFR but the tumor blood vessels express activated EGFR. The EGFR kinase inhibitor, gefitinib (Iressa), retarded tumor growth with a size decrease of 38% compared to control mice, ostensibly due to targeting of the blood vessels. EC were isolated from tumors of gefitinib-treated mice. These EC were unable to proliferate in response to EGF and displayed relatively weaker activation of MAPK and AKT signaling in response to EGF compared to tumor EC isolated from vehicle-treated mice. In contrast, the tumor EC from gefitinib-treated mice expressed higher levels of VEGFR-2 both at the mRNA and protein level. In addition, these cells were less sensitive to EGFR kinase inhibitors in vitro but more sensitive to a VEGFR-2 kinase inhibitor. These results suggest that in tumor EC from gefitinib-treated mice there is a switch from dependence on EGFR activity to signaling via VEGFR-2. Our data provide a molecular rationale for combination therapies targeting both EGF and VEGF signaling on the tumor vasculature. PMID:18440031

Beyond the Didactic Classroom: Educational Models to Encourage Active Student Involvement in Learning  

PubMed Central

In a chiropractic college that utilizes a hybrid curriculum model composed of adult-based learning strategies along with traditional lecture-based course delivery, a literature search for educational delivery methods that would integrate the affective domain and the cognitive domain of learning provided some insights into the use of problem-based learning (PBL), experiential learning theory (ELT), and the emerging use of appreciative inquiry (AI) to enhance the learning experience. The purpose of this literature review is to provide a brief overview of key components of PBL, ELT, and AI in educational methodology and to discuss how these might be used within the chiropractic curriculum to supplement traditional didactic lecture courses. A growing body of literature describes the use of PBL and ELT in educational settings across many disciplines, both at the undergraduate and graduate levels. The use of appreciative inquiry as an instructional methodology presents a new area for exploration and study in the academic environment. Educational research in the chiropractic classroom incorporating ELT and appreciative inquiry might provide some valuable insights for future curriculum development.

Acclimation of Arabidopsis Leaves Developing at Low Temperatures. Increasing Cytoplasmic Volume Accompanies Increased Activities of Enzymes in the Calvin Cycle and in the Sucrose-Biosynthesis Pathway1  

PubMed Central

Photosynthetic and metabolic acclimation to low growth temperatures were studied in Arabidopsis (Heynh.). Plants were grown at 23°C and then shifted to 5°C. We compared the leaves shifted to 5°C for 10 d and the new leaves developed at 5°C with the control leaves on plants that had been left at 23°C. Leaf development at 5°C resulted in the recovery of photosynthesis to rates comparable with those achieved by control leaves at 23°C. There was a shift in the partitioning of carbon from starch and toward sucrose (Suc) in leaves that developed at 5°C. The recovery of photosynthetic capacity and the redirection of carbon to Suc in these leaves were associated with coordinated increases in the activity of several Calvin-cycle enzymes, even larger increases in the activity of key enzymes for Suc biosynthesis, and an increase in the phosphate available for metabolism. Development of leaves at 5°C also led to an increase in cytoplasmic volume and a decrease in vacuolar volume, which may provide an important mechanism for increasing the enzymes and metabolites in cold-acclimated leaves. Understanding the mechanisms underlying such structural changes during leaf development in the cold could result in novel approaches to increasing plant yield.

The effect and value of a WebQuest activity on weather in a 5th grade classroom  

NASA Astrophysics Data System (ADS)

WebQuests are increasing in popularity across the country, yet it remains unclear whether WebQuests confer a significant benefit in student content learning. In addition, the perceptions of teachers regarding the classroom value and efficacy of WebQuests in teaching higher level thinking skills are still unclear. The goals of the study were (a) to determine the effect of WebQuests on elementary students' content area knowledge gains; (b) to investigate teacher perceptions of students' higher order thinking skills while engaged in a WebQuest activity and the value the of the WebQuest, as perceived by teacher. To accomplish the above research goals, a quasi-experimental design was used in this study. The subjects were four teachers and classes at an elementary school in southern California. Results of the study showed that the WebQuest did increase content knowledge in fifth grade students, but not significantly more than traditional teaching as measured by a researcher-modified WebQuest For Teacher Questionnaire (WQFT) (Zheng, Perez, Williamson & Flygare, 2007) and teacher interviews. Teachers responded positively to the value of the WebQuest in their daily teaching. Teachers also indicated that their students engaged in higher level thinking skills while engaged in the WebQuest activity. Keywords: WebQuest, higher level thinking, learning

Wernicke encephalopathy (or Wernicke-Korsakoff encephalopathy) is a rarely diagnosed neurological disorder, which is caused by vitamin B1 deficiency. In the classical form it is characterized by a typical triad (confusion, oculomotor disturbance and ataxia), however, in the majority of the cases only confusion is present. It can be frequently observed in subjects with chronic alcohol consumption, but it may accompany different pathological states of which end stage malignant diseases are the most importants, where confusion may have different backgrounds. The authors present the case of an old male patient with advanced gastric cancer recognised and treated vitamin B1 deficiency, and they draw attention to difficulties of the diagnosis of Wernicke's disease.

Effectiveness of sensory processing strategies on activity level in inclusive preschool classrooms  

PubMed Central

Background The purpose of this study was to investigate the effectiveness of sensory processing strategies in improving the activity level of children with sensory integration dysfunction. Methods The study used a matching-only pretest–posttest control group design, which requires random matching of sensory integration dysfunction to the corresponding intervention group (n = 18) and control group (n = 18). The intervention group comprised 3–6-year-old children who received an 8-week school-day intervention during implementation of the theme curriculum. Results The 8-week treatment significantly reduced the activity level and foot-swinging episodes in children with sensory integration dysfunction, and obtained a medium-effect size. However, the level of improvement in the control group did not show any statistically significant change. Conclusion Sensory processing strategies could improve activity levels in children with sensory integration dysfunction. However, this study was unable to exclude a developmental effect. The social validity results show that sensory processing strategies can be integrated into the theme curriculum and improve activity levels in children.

Comparison of chiropractic student scores before and after utilizing active learning techniques in a classroom setting  

PubMed Central

Objective We report the differences in final examination scores achieved by students at the culmination of two different teaching strategies in an introductory skills course. Methods Multiple choice examination scores from six consecutive academic calendar sessions over 18 months (n = 503) were compared. Two groups were used: Cohort A (n = 290) represented students who were enrolled in the course 3 consecutive academic sessions before an instructional change and Cohort B (n = 213) included students who were enrolled in 3 consecutive academic sessions following the instructional change, which included a more active learning format. Statistical analyses used were 2-tailed independent t-test, one-way ANOVA, Tukey's honestly significant difference (HSD), and effect size. Results The 2-tailed independent t-test revealed a significant difference between the two groups (t = ?3.71, p < .001; 95% confidence interval [CI] 1.29–4.20). Significant difference was found in the highest performing subgroup compared to the lowest performing subgroup in Cohort A (F = 3.343, p = .037). For Cohort A subgroups 1 and 2, Tukey's HSD was p < .028. In Cohort B, no difference was found among subgroups (F = 1.912, p = .150, HSD p > .105). Conclusion Compared to previous versions of the same course taught by the same instructor, the students in the new course design performed better, suggesting that using active learning techniques helps improve student achievement.

NSDL National Science Digital Library

The Active Learning exercise described here has been used to replace some lecture hours in the renal portion of an integrated, organ-system based curriculum for First Year Medical Students. The exercise takes place in a large auditorium with approximately 150 students. Two Faculty, Drs. Dietz (a Physiology) and Dr. Panzarino (a Nephrologist) lead the discussions which are based on two clinical cases developed from actual patient data. The cases have already been published in the APS Teaching Archive previously (Objects 197 & 192). The Students are pre-assigned to groups of 5 or 6 and designated to sit in clusters to facilitate their individual group discussions. Each of the Faculty wears a lapel microphone and each carries a handheld microphone to pass between the student groups.

Gaining A Geological Perspective Through Active Learning in the Large Lecture Classroom  

NASA Astrophysics Data System (ADS)

NATS 101 A Geological Perspective is a general education course taken by non science majors. We offer 600 seats per semester, with four large lecture sections taught by different faculty members. In the past we have offered optional once a week study groups taught by graduate teaching assistants. Students often feel overwhelmed by the science and associated jargon, and many are prone to skipping lectures altogether. Optional study groups are only attended by ~50% of the students. Faculty members find the class to be a lot of work, mainly due to the grading it generates. Activities given in lecture are often short multiple choice or true false assignments, limiting the depth of understanding we can evaluate. Our students often lack math and critical thinking skills, and we spend a lot of time in lecture reintroducing ideas students should have already gotten from the text. In summer 2007 we were funded to redesign the course. Our goals were to 1) cut the cost of running the course, and 2) improve student learning. Under our redesign optional study groups were replaced by once a week mandatory break out sessions where students complete activities that have been introduced in lecture. Break out sessions substitute for one hour of lecture, and are run by undergraduate preceptors and graduate teaching assistants (GTAs). During the lecture period, lectures themselves are brief with a large portion of the class devoted to active learning in small groups. Weekly reading quizzes are submitted via the online course management system. Break out sessions allow students to spend more time interacting with their fellow students, undergraduate preceptors, and GTAs. They get one on one help in break out sessions on assignments designed to enhance the lecture material. The active lecture format means less of their time is devoted to listening passively to a lecture, and more time is spent peer learning an interacting with the instructor. Completing quizzes online allows students more freedom in when and where they complete their work, and we provide instant feedback on their submitted work. The University of Wyoming Cognition in Astronomy, Physics and Earth sciences Research (CAPER) Team, who specialize in project evaluation, are leading the evaluation effort. We are comparing pre-test to post-test gains on the Geoscience Concept Inventory and Attitudes Toward Science surveys before and after the redesign, and inductive analysis of student interviews and reflective writing that describe student perceptions of the modified learning environment. The redesign has cut the cost of the class per student by more than half. This was achieved primarily in two ways: 1) by greatly reducing the number of hours spent by faculty and graduate teaching assistants on preparation, class time, and grading; and 2) reducing the number of graduate teaching assistants required for the class and replacing many of them with undergraduate preceptors. Undergraduate preceptors are not paid, but receive academic credit for their teaching service. The savings from the redesign is used to allow faculty more time to work on institutional priorities.

Does Structured Quizzing with Process Specific Feedback Lead to Learning Gains in an Active Learning Geoscience Classroom?  

NASA Astrophysics Data System (ADS)

There is a great realization that efficient teaching in the geosciences has the potential to have far reaching effects in outreach to decision and policy makers (Herbert, 2006; Manduca & Mogk, 2006). This research in turn informs educators that the geosciences by the virtue of their highly integrative nature play an important role in serving as an entry point into STEM disciplines and helping developing a new cadre of geoscientists, scientists and a general population with an understanding of science. Keeping these goals in mind we set to design introductory geoscience courses for non-majors and majors that move away from the traditional lecture models which don't necessarily contribute well to knowledge building and retention ((Handelsman et al., 2007; Hake, 1997) to a blended active learning classroom where basic concepts and didactic information is acquired online via webquests, lecturettes and virtual field trips and the face to face portions of the class are focused on problem solving exercises. The traditional way to ensure that students are prepared for the in-class activity is to have the students take a quiz online to demonstrate basic competency. In the process of redesign, we decided to leverage the technology to build quizzes that are highly structured and map to a process (formation of divergent boundaries for example) or sets of earth processes that we needed the students to know before in-class activities. The quizzes can be taken multiple times and provide process specific feedback, thus serving as a heuristic to the students to ensure they have acquired the necessary competency. The heuristic quizzes were developed and deployed over a year with the student data driving the redesign process to ensure synchronicity. Preliminary data analysis indicates a positive correlation between higher student scores on in-class application exercises and time spent on the process quizzes. An assessment of learning gains also indicate a higher degree of self efficacy among students who took the quizzes multiple times vs. the students who took the quizzes just enough times to ensure a passing grade.

Geomicrobiological exploration and characterization of novel deep-sea hydrothermal activities accompanying with extremely acidic white smokers and elemental sulfur chimneys at the TOTO caldera in the Mariana Volcanic Arc  

NASA Astrophysics Data System (ADS)

Novel hydrothermal activities accompanying effluent white smokers and elemental sulfur chimney structures at the northeast lava dome of the TOTO caldera depression in the Mariana Volcanic Arc were explored by the manned submersible Shinkai 6500 and characterized by geochemical and microbiological surveys. The white smoker hydrothermal fluids were observed in the potential hydrothermal activity center of the field and represented a maximal temperature of 172 degree C and a lowest pH of 1.59, that was the lowest pH of the hydrothermal fluid ever recorded. The chimney structures consisting all of elemental sulfur (sulfur chimney) were also peculiar to the TOTO caldera hydrothermal field in the world. The geochemical characterization strongly suggested that the TOTO caldera hydrothermal field was a novel system driven by subseafloor mixing between the oxygenated seawater and the superheated volcanic gasses. Microbial community structures in a sulfur chimney structure and its formation hydrothermal fluid with a high concentration of hydrogen sulfide (15 mM) were investigated by culture-dependent and _|independent analyses. Ribosomal rRNA gene clone analysis and fluorescence in situ hybridization (FISH) analysis revealed that epsilon-Proteobacteria, specifically classified into Group G and Group B, dominated the microbial communities in the sulfur chimney structure and formed a dense microbial mat covering the sulfur chimney surface. Archaeal phylotypes were consistently minor components in the communities and related to the genera Thermococcus, Pyrodictium, Aeropyrum, and the uncultivated archaeal group of Deep-sea Hydrothermal Vent Euryarchaeotal Group. Cultivation analysis suggested that the microbial components inhabiting in the sulfur chimney structure might be entrained by hydrothermal fluids from the potential subsurface habitats

A Case of Cluster Headache Accompanied by Myoclonus and Hemiparesis  

PubMed Central

Background Cluster headache is a primary headache disorder characterized by periodic episodes of intense headache accompanied by autonomic symptoms. We report an unusual clinical presentation of cluster headache that was preceded by myoclonus and accompanied by hemiparesis. Case Report A 26-year-old man visited hospital due to recurrent jerky movements on the left side of his face and neck area lasting 3 days. These jerky movements had disappeared spontaneously without specific treatment. On the 10th day after onset of the jerky movements, the patient developed a series of unilateral severe headaches that were accompanied by autonomic symptoms lasting 1-2 hours. According to the second edition of The International Classification of Headache Disorders, he was diagnosed as having cluster headache. Two of the 16 severe headache attacks this patient suffered were accompanied by dysarthria and hemiparesis. Electroencephalography performed during hemiparesis revealed diffuse lateralized slow activity on the ipsilateral hemisphere of the headache side. The headache and accompanying hemiparesis disappeared after medical treatment for cluster headache. Conclusions We describe a case of cluster headache accompanied by hemiparesis, which was preceded by myoclonus. We also outline the possible mechanisms underlying this case.

An analysis of science instruction in the fifth-grade science classroom: Investigating activity-based instruction with student-generated discussion  

NASA Astrophysics Data System (ADS)

The purpose of this study was to determine the extent to which debriefing impacts the level of cognitive understanding among students in the fifth-grade science classroom. This mixed methods study involved two fifth-grade science classrooms (N = 39) in a one month exploration of rocks and minerals. Two fifth-grade science classrooms participated in a unit using identical content, but had different pedagogical orientations. The experimental class was taught using the "Do-Talk-Do-Debrief" instructional method and the control class was taught using the "Do-Talk-Do" instructional method without the "Debrief" (metacognitive component). Research for the quantitative portion of this study was conducted using a pretest-posttest control-group design. The design was used to test the hypothesized relationship between an activity-based instructional method with debriefing and students' achievement. Two intact, equivalent fifth-grade classes were randomly assigned to treatment and control conditions. Prior to the beginning of the study, a researcher-developed pretest was administered to all participants to assess the students' prior knowledge of rocks and minerals. A posttest measure was given to the participants upon conclusion of the unit to measure knowledge and understanding. Following the posttest, the participants did not receive additional instruction over rocks and minerals. A similar posttest was administered to both groups two weeks later as an added measure for retention. A t-test for independent samples was used to examine differences on the pretest between the experimental and control groups. Likewise, a t-test was used to compare the mean scores on the first posttest (achievement). A separate t-test was conducted on the second posttest (retention) and was followed by a Pearson Product Moment Correlation, conducted by group. Research for the qualitative portion of this study involved classroom observations throughout the rock and mineral unit followed by a teacher interview. Observations were made in two fifth-grade classrooms and Flanders' Categories for Interaction Analysis was used as a framework for observing the level of social interaction. The observations were transcribed and developed into a "thick" record as suggested by Dr. Phil Carspecken's stages of qualitative research. Member checking and peer debriefing techniques were employed to increase the trustworthiness of the study. The quantitative data suggested science achievement of fifth-grade science students who learned through activity-based instruction with debriefing was statistically significantly higher than the science achievement of fifth-grade science students who learned through activity-based instruction without debriefing (p<.01), as measured by the first posttest. Also, student retention as measured by fifth-grade science students who learned through activity-based instruction was statistically significantly higher than fifth-grade science students who learned through activity-based instruction without debriefing (p<.01), as measured by the second posttest. Additionally, the effect sizes for achievement and retention were very large and educationally meaningful. Activity-based instruction enhanced with debriefing resulted in a deeper construction of knowledge and retention of understanding.

The Zooniverse: Cutting Edge Scientific Research in the Classroom  

NASA Astrophysics Data System (ADS)

Increasingly scientists and researchers from a multitude of disciplines are finding themselves inundated with more data than they could possibly interpret in a lifetime. Computers can be used entirely or partially for some data analysis; but there are some tasks that are currently best suited to human eyes, ears and brains. Zooniverse (www.zooniverse.org) invites members of the public to help researchers analyze and interpret data. To date, hundreds of thousands of volunteers have been involved in classifying images, interpreting sounds and transcribing texts. Zooniverse citizen scientists are providing valuable analyses across a variety of fields, from the hunt for exoplanets in Planet Hunters (planethunters.org) to the transcription of Greek papyri in Ancient Lives (ancientlives.org). Multiple academic publications have resulted from the combined efforts of the Zooniverse community and science teams demonstrating that citizen science is more than ever becoming a well-established method of doing research. Unlike most research projects the data, analysis and interactions with the science teams have an established and visible online presence through the project website and related discussion sites and blogs. These in themselves provide a valuable classroom resource, an opportunity for free and easy access to cutting edge scientific research. Anecdotal evidence exists that teacher can and already do use Zooniverse projects. By providing a rich and varied scaffolding to accompany the Zooniverse projects the opportunity exists for bringing citizen scientists to a wider classroom audience. An audience that may include non-specialist teachers, who require additional support to deliver challenging content, or time strapped educators who haven't the time to develop their own accompanying resources to weave Zooniverse projects into their lessons. During the session we will discuss the recent Zooniverse projects specifically designed to support and promote classroom adoption locally, within the Chicago Public School (CPS) system and nationally within the United States. Introducing ZooTeach, a website where educators may share and search for lesson plans, activities, and resources. Beyond a simple lesson plan repository, ZooTeach is a community where educators are encouraged to modify, comment on, and otherwise actively participate in the educational efforts of Zooniverse. Teacher workshops run at Adler have and will continue to have the dual effect of promoting the Zooniverse and it's educational effort while increasing the pool of resources available nationally via ZooTeach. In house developed teacher guides and interactive tools allowing for the collection and manipulation of data will further enhance the classroom education experience and further lower the bar for entry into the world of citizen science.

Classroom Solar Calendar  

NSDL National Science Digital Library

In this activity, students engage in an ongoing investigation to find patterns of sunlight and shadow in a classroom (or any room that gets sunlight) at different times of the day and different times of the year. Students look for repeating patterns, keep a log to describe and sketch observations of when and where certain easily recognized patters appear and turn the room into a solar calendar that may survive into the future for other classes to use. Part 1 of this activity requires occasional note-taking and casual observation over the course of a day. Part 2 requires 30-60 minutes to create the calendar record, then casual observation and note-taking throughout the school year. The lesson plan includes a math extension activity and background information about the Sun Dagger at Chaco Canyon. This activity is the third lesson in the Ancient Eyes Look to the Skies curriculum guide.

The role of assessment infrastructures in crafting project-based science classrooms  

NASA Astrophysics Data System (ADS)

In project-based science teaching, teachers engage students in the practice of conducting meaningful investigations and explanations of natural phenomena, often in collaboration with fellow students or adults. Reformers suggest that this approach can provide students with more profitable learning experiences; but for many teachers, a shift to such instruction can be difficult to manage. As some reform-minded teachers have discovered, classroom assessment can serve as a vital tool for meeting the challenges associated with project science activity. In this research, classroom assessment was viewed as an infrastructure that both students and teachers rely upon as a mediational tool for classroom activity and communications. The study explored the classroom assessment infrastructures created by three teachers involved in the Learning through Collaborative Visualization (CoVis) Project from 1993--94 to 1995--96. Each of the three teachers under study either created a new course or radically reformulated an old one in an effort to incorporate project-based science pedagogy and supporting technologies. Data in the form of interviews, classroom observations, surveys, student work, and teacher records was collected. From these data, an interpretive case study was developed for each course and its accompanying assessment infrastructure. A set of cross-case analyses was also constructed, based upon common themes that emerged from all three cases. These themes included: the assessment challenges based on the nature of project activity, the role of technology in the teachers' assessment infrastructure designs, and the influence of the wider assessment infrastructure on their course and assessment designs. In combination, the case studies and cross-case analyses describe the synergistic relationship between the design of pedagogical reforms and classroom assessment infrastructures, as well as the effectiveness of all three assessment designs. This work contributes to research and practice associated with assessment and pedagogical reform in three ways. First, it provides a theoretical frame for the relationship between assessment and pedagogical reform. Second, it provides a set of taxonomies which outline both the challenges of project-based science activity and typical assessment strategies to meet them. Finally, it provides a set of cautions and recommendations for designing classroom assessment infrastructures in support of project-based science.

Hairy cell leukemia accompanied by Evans syndrome.  

PubMed

We report a case of Western type hairy cell leukemia (HCL), a very rare leukemia in Japan. In this malignancy, leukemic cells in a peripheral blood film may be missed due in part to accompanying pancytopenia and in part to loss of typical cytoplasmic projections if prepared in a conventional Japanese way using forced air-drying. Our present patient also had a variety of autoantibodies and the clinical picture was primarily that of Evans syndrome (ES), suggesting disturbed immune responses associated with the HCL. Although HCL accompanied by either AIHA or ITP has been reported, the occurrence of ES in HCL is extremely rare. PMID:24850460

A randomized controlled pilot trial of classroom-based mindfulness meditation compared to an active control condition in sixth-grade children.  

PubMed

The current study is a pilot trial to examine the effects of a nonelective, classroom-based, teacher-implemented, mindfulness meditation intervention on standard clinical measures of mental health and affect in middle school children. A total of 101 healthy sixth-grade students (55 boys, 46 girls) were randomized to either an Asian history course with daily mindfulness meditation practice (intervention group) or an African history course with a matched experiential activity (active control group). Self-reported measures included the Youth Self Report (YSR), a modified Spielberger State-Trait Anxiety Inventory, and the Cognitive and Affective Mindfulness Measure -Revised. Both groups decreased significantly on clinical syndrome subscales and affect but did not differ in the extent of their improvements. Meditators were significantly less likely to develop suicidal ideation or thoughts of self-harm than controls. These results suggest that mindfulness training may yield both unique and non-specific benefits that are shared by other novel activities. PMID:24930819

Interactive learning activities for the middle school classroom to promote healthy energy balance and decrease diabetes risk in the HEALTHY primary prevention trial.  

PubMed

The HEALTHY trial evaluated the effectiveness of a multicomponent intervention program to reduce risk for type 2 diabetes in middle school students. The comprehensive intervention addressed nutrition, physical activity, and behavior in the context of a social marketing-based communications campaign to promote healthy energy balance. One element was a classroom-based program called FLASH (Fun Learning Activities for Student Health). Five FLASH modules were delivered, one per semester. Process evaluation data were collected from teachers at 21 schools and study staff at seven national sites via survey, interview, and in-class observation. Data from the first four modules were evaluated and showed that FLASH was delivered with high fidelity. Sessions that required peer interaction were rated as the most effective in engaging students and promoting knowledge. Study-provided material resources and on-site support were identified as key facilitators. Student misbehavior was viewed as the greatest barrier. Although the high level of support provided by the study is not likely to be replicated in school systems, those developing wellness policies, health curricula, and teacher training programs may benefit from using the evidence-supported, publicly available HEALTHY materials in their efforts to reduce diabetes risk factors in middle school youth.

Herpesviruses and human endogenous retroviruses (HERVs) represent potentially important factors in MS development. Herpesviruses can activate HERVs, and HERVs are activated in MS patients. Results Using flow cytometry, we have analyzed HERV-H Env and HERV-W Env epitope expression on the surface of PBMCs from MS patients with active and stable disease, and from control individuals. We have also analyzed serum antibody levels to the expressed HERV-H and HERV-W Env epitopes. We found a significantly higher expression of HERV-H and HERV-W Env epitopes on B cells and monocytes from patients with active MS compared with patients with stable MS or control individuals. Furthermore, patients with active disease had relatively higher numbers of B cells in the PBMC population, and higher antibody reactivities towards HERV-H Env and HERV-W Env epitopes. The higher antibody reactivities in sera from patients with active MS correlate with the higher levels of HERV-H Env and HERV-W Env expression on B cells and monocytes. We did not find such correlations for stable MS patients or for controls. Conclusion These findings indicate that both HERV-H Env and HERV-W Env are expressed in higher quantities on the surface of B cells and monocytes in patients with active MS, and that the expression of these proteins may be associated with exacerbation of the disease.

The mechanism of atomization accompanying solid injection  

NASA Technical Reports Server (NTRS)

A brief historical and descriptive account of solid injection is followed by a detailed review of the available theoretical and experimental data that seem to throw light on the mechanism of this form of atomization. It is concluded that this evidence indicates that (1) the atomization accompanying solid injection occurs at the surface of the liquid after it issues as a solid stream from the orifice; and (2) that such atomization has a mechanism physically identical with the atomization which takes place in an air stream, both being due merely to the formation, at the gas-liquid interface, of fine ligaments under the influence of the relative motion of gas and liquid, and to their collapse, under the influence of surface tension, to form the drops in the spray.

Online Classroom Research and Analysis Activities Using MARGINS-Related Resources for the Izu-Bonin-Mariana Subduction System  

NASA Astrophysics Data System (ADS)

Students today have online access to nearly unlimited scientific information in an entirely unfiltered state. As such, they need guidance and training in identifying and assessing high-quality information resources for educational and research use. The extensive research data resources available online for the Izu-Bonin-Mariana (IBM) subduction system that have been developed with MARGINS Program and related NSF funding are an ideal venue for focused Web research exercises that can be tailored to a range of undergraduate geoscience courses. This presentation highlights student web research activities examining: a) The 2003-2005 eruptions of Anatahan Volcano in the Mariana volcanic arc. MARGINS-supported geophysical research teams were in the region when the eruption initiated, permitting a unique "event response" data collection and analysis process, with preliminary results presented online at websites linked to the MARGINS homepage, and ultimately published in a special issue of the Journal of Volcanology and Geothermal Research. In this activity, students will conduct a directed Web surf/search effort for information on and datasets from the Anatahan arc volcano, which they will use in an interpretive study of recent magmatic activity in the Mariana arc. This activity is designed as a homework exercise for use in a junior-senior level Petrology course, but could easily be taken into greater depth for the benefit of graduate-level volcanology or geochemistry offerings. b) Geochemical and mineralogical results from ODP Legs 125 and 195 focused on diapiric serpentinite mud volcanoes, which erupt cold, high pH fluids, serpentine muds, and serpentinized ultramafic clasts at a number of sites in the forearc region of the Mariana subduction zone. The focus of this activity is an examination of the trace element chemistry of the forearc serpentines and their associated upwelling porefluids as a means of understanding the roles of ionic radius, valence, and system abundance in the formation and trace element systematics of serpentine group minerals.

Surface properties of bacillus Calmette-Guerin-activated mouse macrophages. Reduced expression of mannose-specific endocytosis, Fc receptors, and antigen F4/80 accompanies induction of Ia  

PubMed Central

Infection of the mouse peritoneal cavity by bacillus Calmette-Guerin (BCG) markedly alters the surface properties of the macrophages induced, compared with cells obtained from uninfected control animals or after injection of thioglycollate broth. Quantitative binding assays with radiolabeled ligands or antibodies showed that BCG-activated peritoneal macrophages (BCG-PM) expressed one-fourth or less receptor activity for mannose-terminal glycoconjugates as well as reduced levels of Fc receptors and of antigen F4/80 compared with nonactivated macrophages. Endocytosis mediated by mannose-specific receptors was reduced in parallel. In contrast, surface Ia antigen was increased threefold in the same adherent cell population. Radioautographic analysis confirmed that greater than 80% of adherent cells still expressed low levels of the macrophage-specific mannosyl receptor and antigen F4/80, and that I antigens had been induced on 64% of macrophages rather than on other cells. Control experiments established that only the BCG-PM macrophages released H2O2 after stimulation with phorbol myristate acetate, whereas both BCG-PM and thioglycollate- induced macrophages produced superoxide anion and plasminogen activator. The BCG-PM were viable, secreted normal levels of lysozyme, and displayed a stable phenotype after cultivation for 60 h. Inhibitors of oxygen products, prostaglandins, and proteases did not alter reduced endocytosis by BCG-PM. These studies indicated that expression of macrophage surface markers is reversed by BCG-activation, and that their known enhanced ability to lyse target cells extracellularly is associated with decreased endocytosis via specific receptors. Whether these changes are a result of an altered cell population or of modulation of selective surface properties is not known.

Constitutively active type I insulin-like growth factor receptor causes transformation and xenograft growth of immortalized mammary epithelial cells and is accompanied by an epithelial-to-mesenchymal transition mediated by NF-kappaB and snail.  

PubMed

Type I insulin-like growth factor receptor (IGF-IR) can transform mouse fibroblasts; however, little is known about the transforming potential of IGF-IR in human fibroblasts or epithelial cells. We found that overexpression of a constitutively activated IGF-IR (CD8-IGF-IR) was sufficient to cause transformation of immortalized human mammary epithelial cells and growth in immunocompromised mice. Furthermore, CD8-IGF-IR caused cells to undergo an epithelial-to-mesenchymal transition (EMT) which was associated with dramatically increased migration and invasion. The EMT was mediated by the induction of the transcriptional repressor Snail and downregulation of E-cadherin. NF-kappaB was highly active in CD8-IGF-IR-MCF10A cells, and both increased levels of Snail and the EMT were partially reversed by blocking NF-kappaB or IGF-IR activity. This study places IGF-IR among a small group of oncogenes that, when overexpressed alone, can confer in vivo tumorigenic growth of MCF10A cells and indicates the hierarchy in the mechanism of IGF-IR-induced EMT.
