Active Learning in the College Science Classroom  

NSDL National Science Digital Library

Research has consistently shown that all students, including college science students, learn more when activity engaged. Engagement can occur through increased interaction with the content itself, or it may be coupled with increased interaction with peers or the course instructor. These strategies not only mirror many of the processes of scientific inquiry and accommodate different interests and learning preferences, but they are also helpful in attracting and retaining women and students of color in the sciences. This chapter describes some active-learning strategies that can be effectively used in the college science classroom.

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.

Classroom Activities about Water and Climate Change  

NASA Astrophysics Data System (ADS)

The purpose of this activity is to demonstrate practical work and experiments in the classroom, with students on Water: Water is the most neccesary Earth's resource, although it is decreasing because many human activities are changing its quality and its availability. The activity is designed in order to recreate experiments, simulations, and determine the aspects of the problematic environment currently plaguing our planet, especially those related to water and climate change. The selected activities have to be easy to make, and easy to understand. Each activity will be illustrated, explained and described using pictures and short texts, so teachers could replay them in their classroom. 1. Simulation of the Ocean Water Currents Convection to understand the heat distribution in our planet. 2. Ocean Water Stratification According to Water Salinity. We can understand the behaviour of water when we mix water from different densities 3. Melting of the Arctic and Antarctic Polar Caps. In this experiment, we can see the consequences of changing environment and climate conditions as it pertains to ice and our polar ice caps. We want to show the different behaviours of continental and floating ice and to evaluate the consequences of their melting. 4. Detecting water pollution. Here, we can analyse some water patterns and get to know the existence or absence of pollutants in the water, as well as learning how to determine its pH level, hardness, nitrogen composition, bacteria content and more. 5. Creating a home treatment. We show the necessity to preserve the water quality through a suitable treatment.

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.

The discourse of design-based science classroom activities  

NASA Astrophysics Data System (ADS)

This paper is an initial contribution to a general theory in which science classroom activity types and epistemological discourse practices are systematically linked. The idea is that activities and discourse are reflexively related, so that different types of science classroom activities (e.g., scientific argumentation, modeling, and design) recruit characteristically distinct forms of participants' (students and teacher) discourse. Such a general theory would eventually map out the full spectrum of discourse practices (and their patterns of manifestation) across various kinds of science classroom activities, and reveal new relationships between forms of both discourse and activities. Because this defines a complex and long-term project, here our aim is simply to delineate this larger theoretical program and to illustrate it with a detailed case study—namely, that of mapping out and characterizing the discourse practices of design-based science classroom activities. To do so, we draw on data from an activity that is prototypically design-based—i.e., one in which students iteratively design and refine an artifact (in this case, pictorial representations of moving objects)—and examine the structure and dynamics of the whole-class discourse practices that emerge around these representational forms. We then compare and contrast these discourse practices to those of an activity that is prototypical of scientific argumentation (taken from the literature)—i.e., one in which students argue between competing theories and explanations of a phenomenon—and begin to illustrate the kinds of insights our theoretical program might afford.

NSDL National Science Digital Library

In the article "The Big Picture: A Classroom Activity for Organic Chemistry", Thomas Poon makes interesting use of the device exploited by Istvan Banyai in his Zoom books to help students of organic chemistry make connections between the molecular world and ways in which those molecules are important in daily life. The paper should have appeal at all levels of science education from the time the idea of molecules is first introduced through college-level courses. Along the way, students will encounter important biological molecules (such as chlorophyll), inks (such as pen ink), CFCs, hydrocarbon fuels, plastics (such as Lexan polycarbonate), and molecules with medical applications (such as aspirin and novocaine).

Systemic ?-Adrenergic Stimulation of Thermogenesis Is Not Accompanied by Brown Adipose Tissue Activity in Humans  

PubMed Central

Brown adipose tissue (BAT) is currently considered as a target to combat obesity and diabetes in humans. BAT is densely innervated by the sympathetic nervous system (SNS) and can be stimulated by ?-adrenergic agonists, at least in animals. However, the exact role of the ?-adrenergic part of the SNS in BAT activation in humans is not known yet. In this study, we measured BAT activity by 2-deoxy-2-[18F]fluoro-d-glucose ([18F]FDG) positron emission tomography/computed tomography imaging in 10 lean men during systemic infusion of the nonselective ?-agonist isoprenaline (ISO) and compared this with cold-activated BAT activity. ISO successfully mimicked sympathetic stimulation as shown by increased cardiovascular and metabolic activity. Energy expenditure increased to similar levels as during cold exposure. Surprisingly, BAT was not activated during ?-adrenergic stimulation. We next examined whether the high plasma free fatty acid (FFA) levels induced by ISO competed with glucose ([18F]FDG) uptake in BAT locations by blocking lipolysis with acipimox (ACI). ACI successfully lowered plasma FFA, but did not increase [18F]FDG-uptake in BAT. We therefore conclude that systemic nonselective ?-adrenergic stimulation by ISO at concentrations that increase energy expenditure to the same extent as cold exposure does not activate BAT in humans, indicating that other tissues are responsible for the increased ?-adrenergic thermogenesis.

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.

Caspase-Like Activities Accompany Programmed Cell Death Events in Developing Barley Grains  

PubMed Central

Programmed cell death is essential part of development and cell homeostasis of any multicellular organism. We have analyzed programmed cell death in developing barley caryopsis at histological, biochemical and molecular level. Caspase-1, -3, -4, -6 and -8-like activities increased with aging of pericarp coinciding with abundance of TUNEL positive nuclei and expression of HvVPE4 and HvPhS2 genes in the tissue. TUNEL-positive nuclei were also detected in nucellus and nucellar projection as well as in embryo surrounding region during early caryopsis development. Quantitative RT-PCR analysis of micro-dissected grain tissues revealed the expression of HvVPE2a, HvVPE2b, HvVPE2d, HvPhS2 and HvPhS3 genes exclusively in the nucellus/nucellar projection. The first increase in cascade of caspase-1, -3, -4, -6 and -8-like activities in the endosperm fraction may be related to programmed cell death in the nucellus and nucellar projection. The second increase of all above caspase-like activities including of caspase-9-like was detected in the maturating endosperm and coincided with expression of HvVPE1 and HvPhS1 genes as well as with degeneration of nuclei in starchy endosperm and transfer cells. The distribution of the TUNEL-positive nuclei, tissues-specific expression of genes encoding proteases with potential caspase activities and cascades of caspase-like activities suggest that each seed tissue follows individual pattern of development and disintegration, which however harmonizes with growth of the other tissues in order to achieve proper caryopsis development.

Activation of Alpha Chymotrypsin by Three Phase Partitioning Is Accompanied by Aggregation  

PubMed Central

Precipitation of alpha chymotrypsin in the simultaneous presence of ammonium sulphate and t-butanol (three phase partitioning) resulted in preparations which showed self aggregation of the enzyme molecules. Precipitation with increasing amounts of ammonium sulphate led to increasing size of aggregates. While light scattering estimated the hydrodynamic diameter of these aggregates in the range of 242–1124 nm; Nanoparticle tracking analysis (NTA) gave the value as 130–462 nm. Scanning electron microscopy and gel filtration on Sephadex G-200 showed extensive aggregation in these preparations. Transmission electron microscopy showed that the aggregates had irregular shapes. All the aggregates had about 3× higher catalytic activity than the native enzyme. These aggregates did not differ in ?max of fluorescence emission which was around 340 nm. However, all the aggregates showed higher fluorescence emission intensity. Far-UV and near-UV circular dichroism also showed no significant structural changes as compared to the native molecule. Interestingly, HPLC gel filtration (on a hydroxylated silica column) gave 14 nm as the diameter for all preparations. Light scattering of preparations in the presence of 10% ethylene glycol also dissociated the aggregates to monomers of 14 nm. Both these results indicated that hydrophobic interactions were the driving force behind this aggregation. These results indicate: (1) Even without any major structural change, three phase partitioning led to protein molecules becoming highly prone to aggregation. (2) Different methods gave widely different estimates of sizes of aggregates. It was however possible to reconcile the data obtained with various approaches. (3) The nature of the gel filtration column is crucial and use of this technique for refolding and studying aggregation needs a rethink. PMID:23239966

Age?related remodeling of small arteries is accompanied by increased sphingomyelinase activity and accumulation of long?chain ceramides  

PubMed Central

Abstract The structure and function of large arteries alters with age leading to increased risk of cardiovascular disease. Age?related large artery remodeling and arteriosclerosis is associated with increased collagen deposition, inflammation, and endothelial dysfunction. Bioactive sphingolipids are known to regulate these processes, and are also involved in aging and cellular senescence. However, less is known about age?associated alterations in small artery morphology and function or whether changes in arterial sphingolipids occur in aging. We show that mesenteric small arteries from old sheep have increased lumen diameter and media thickness without a change in media to lumen ratio, indicative of outward hypertrophic remodeling. This remodeling occurred without overt changes in blood pressure or pulse pressure indicating it was a consequence of aging per se. There was no age?associated change in mechanical properties of the arteries despite an increase in total collagen content and deposition of collagen in a thickened intima layer in arteries from old animals. Analysis of the sphingolipid profile showed an increase in long?chain ceramide (C14–C20), but no change in the levels of sphingosine or sphingosine?1?phosphate in arteries from old compared to young animals. This was accompanied by a parallel increase in acid and neutral sphingomyelinase activity in old arteries compared to young. This study demonstrates remodeling of small arteries during aging that is accompanied by accumulation of long?chain ceramides. This suggests that sphingolipids may be important mediators of vascular aging. PMID:24872355

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.

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.

Seismic activity that accompanied the effusive and explosive eruptions during the 2004-2005 period at Volcán de Colima, Mexico  

NASA Astrophysics Data System (ADS)

Volcán de Colima is considered the most active in Mexico. A period of large eruptive activity occurred in 2004-2005. It began as a swarm of long-period events (LPs) in late September 2004, indicating the onset of growth of a new lava dome in its crater. Subsequently, avalanches of incandescent material and pyroclastic flows during a period of approximately 2 months occurred. Then, the activity became more explosive with moderate explosions. Finally, swarms of LPs accompanied the magma ascent and extrusion of small domes and vulcanian explosions with pyroclastic flows in 2005. This eruptive period was investigated with a continuous seismic signal study, cross-correlation of LPs and autoregressive analysis of monochromatic LPs. For the vast majority of the explosions, an increase in the rate of seismic energy was observed with the Seismic Spectral Energy Measurement (SSEM) from 1 to 3 Hz, before each explosive event. This increase in energy is proportional to the increase in the rate of LPs, probably as a result of an increase in the emission rate. Applying the material failure forecasting method (FFM) and using SSEM inverse of parameter, the time of the explosions is estimated as the time when the adjusted line reaches the null value. We observe a systematic delay of a few hours between the real time of occurrence of the explosions and the estimated time. This suggests that more complex processes than pure damaging of the plug occur before the explosions. The swarms associated with the large explosions include a large proportion of LPs with similar waveforms. They form a dozen of families which stay during the whole period of activity and which indicate repetitive sources. Some of the families are active only before the explosions and could therefore be used as early warning. Monochromatic LP events occurred during this period, some of them just some hours before an explosion. However, no clear relationship between their occurrence and the explosions could be found.

Ectopic Lipid Accumulation and Reduced Glucose Tolerance in Elderly Adults Are Accompanied by Altered Skeletal Muscle Mitochondrial Activity  

PubMed Central

Context: Aging is associated with insulin resistance and unfavorable changes in body composition including increased fat accumulation, particularly in visceral and ectopic depots. Recent studies suggest that skeletal muscle mitochondrial activity may underlie some age-associated metabolic abnormalities. Objective: Our objective was to measure mitochondrial capacity and coupling of the vastus lateralis muscle in elderly and young adults using novel in vivo approaches and relate mitochondrial activity to metabolic characteristics. Design: This was a cross-sectional study. Participants and Intervention: Fourteen sedentary young (seven males and seven females, 20–34 yr of age) and 15 sedentary elderly (seven males and eight females, 70–84 yr of age) nonobese subjects selected for similar body weight underwent measures of body composition by magnetic resonance imaging and dual-energy x-ray absorptiometry, oral glucose tolerance, and in vivo mitochondrial activity by 31P magnetic resonance and optical spectroscopy. Muscle biopsy was carried out in the same muscle to measure mitochondrial content, antioxidant activity, fiber type, and markers of mitochondrial biogenesis. Results: Elderly volunteers had reduced mitochondrial capacity (P = 0.05) and a trend for decreased coupling efficiency (P = 0.08) despite similar mitochondrial content and fiber type distribution. This was accompanied by greater whole-body oxidative stress (P = 0.007), less skeletal muscle mass (P < 0.001), more adipose tissue in all depots (P ? 0.002) except intramyocellular (P = 0.72), and lower glucose tolerance (P = 0.07). Conclusions: Elderly adults show evidence of altered mitochondrial activity along with increased adiposity, oxidative stress, and reduced glucose tolerance, independent of obesity. We propose that mild uncoupling may be induced secondary to age-associated oxidative stress as a mechanism to dissipate the proton-motive force and protect against further reactive oxygen species production and damage.

Leukemia inhibitory factor promotes porcine oocyte maturation and is accompanied by activation of signal transducer and activator of transcription 3.  

PubMed

We produced recombinant porcine leukemia inhibitory factor (pLIF) and examined its effect on in vitro maturation (IVM) of porcine oocytes and their developmental competence after in vitro fertilization. Porcine cumulus-oocyte complexes (COCs) were matured in a medium supplemented with pLIF during the first 22 hr, last 22 hr, or entire 44 hr duration of IVM. Oocytes in all groups tended to show enhanced nuclear maturation rates by the metaphase II (MII) stage (76.1%, 82.1%, and 86.6%, respectively) compared to the without-pLIF treatment group (69.6%, control). A significant increase in MII rate (P < 0.05) and obvious induction of cumulus expansion were observed over the whole time span (44 hr) in the IVM group. When cumulus cells were removed at 22 hr and denuded oocytes were further cultured, pLIF showed no effect on maturation rate. Oocytes matured in pLIF-supplemented medium showed a tendency for more rapid blastocyst development (21.1% vs. 16.2%, P = 0.0715). Examination of transcripts and proteins of the LIF signaling pathway in COCs revealed that LIF, LIF receptors, and signal transducer and activator of transcription 3 (STAT3) are present in both cumulus cells and oocytes. The amount of phosphorylated STAT3 (p-STAT3) markedly increased in both cumulus cells and oocytes cultured in pLIF-supplemented media, although oocyte p-STAT3 disappeared after 44 hr of IVM. These results suggest that the LIF/STAT3 pathway is functional during IVM of porcine oocytes, and supplementing pLIF in the IVM medium can improve oocyte maturation by activating this pathway.

PubMed

This article focuses on the important role of the school nurse in promoting healthy lifestyle choices through networking, resource identification, and working with community partners. "Everyone Is Healthy at Northeast" was a health promotion program designed and presented in two ways: classroom lessons and a health fair. There were interactive health promotion classroom lessons on topics such as proper hand washing, the effects of tobacco, and keeping one's heart healthy. These lessons were enhanced by community partners in delivering the healthy lifestyle message through a variety of teaching methods: music, interactive games, and hands-on visuals. The health promotion education program culminated in a schoolwide health fair that showcased the healthy lifestyle choice information at various stations. "Everyone Is Healthy at Northeast" was a success and promoted healthy lifestyle choices through creativity, collaboration, and support from the entire school community. PMID:14731105

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.

Sulfoxide stimulation of chondrogenesis in limb mesenchyme is accompanied by an increase in type II collagen enhancer activity  

SciTech Connect

We have utilized a modification of the limb bud mesenchyme micromass culture system to screen compounds that might stimulate chondrogenesis. Two compounds in the sulfoxide family (methylphenylsulfoxide and p-chlorophenyl methyl sulfoxide) were stimulatory at 10(-2) M and 10(-3) M, respectively; whereas other sulfoxides and organic solvents were not active at these concentrations. In addition, specific growth factors (basic FGF, IGF-I, IGF-II) were not chondroinductive at concentrations that are active in other cell systems. Both sulfoxide compounds stimulated cartilage nodule formation, ({sup 35}S)sulfate incorporation, and activity of the regulatory sequences of the collagen II gene. In contrast, transforming growth factor beta-1 (10 ng/ml) stimulated sulfate incorporation but produced only a diffuse deposition of cartilage matrix and reduced the ability of the cells to utilize the regulatory sequences of the collagen II gene. The sulfoxides appear to promote the differentiation of limb bud cells to chondrocytes and thus exhibit chondroinductive activity.

Transpositional activation of mPing in an asymmetric nuclear somatic cell hybrid of rice and Zizania latifolia was accompanied by massive element loss.  

PubMed

We have reported previously that the most active miniature inverted terminal repeat transposable element (MITE) of rice, mPing, was transpositionally mobilized in several rice recombinant inbred lines (RILs) derived from an introgressive hybridization between rice and wild rice (Zizania latifolia Griseb.). To further study the phenomenon of hybridization-induced mPing activity, we undertook the present study to investigate the element's behavior in a highly asymmetric somatic nuclear hybrid (SH6) of rice and Z. latifolia, which is similar in genomic composition to that of the RILs, though probably contains more introgressed alien chromatins from the donor species than the RILs. We found that mPing, together with its transposase-donor, Pong, underwent rampant transpositional activation in the somatic hybrid (SH6). Because possible effects of protoplast isolation and cell culture can be ruled out, we attribute the transpositional activation of mPing and Pong in SH6 to the process of asymmetric somatic hybridization, namely, one-step introgression of multiple chromatin segments of the donor species Z. latifolia into the recipient rice genome. A salient feature of mPing transposition in the somatic hybrid is that the element's activation was accompanied by massive loss of its original copies, i.e., abortive transpositions, which was not observed in previously reported cases of mPing activity. These data not only corroborated our earlier finding that wide hybridization and introgression may trigger transpositional activation of otherwise quiescent transposable elements, but also suggest that transpositional mobilization of a MITE like mPing can be accompanied by dramatic reduction of its original copy numbers under certain conditions, thus provide novel insights into the dynamics of MITEs in the course of genome evolution.

Nerve growth factor-induced differentiation of PC12 cells is accompanied by elevated adenylyl cyclase activity.  

PubMed

Rat pheochromocytoma (PC12) cells characteristically undergo differentiation when cultured with nerve growth factor (NGF). Here we show that NGF dramatically increased the adenylyl cyclase-activating property of forskolin in PC12 cells. This effect of NGF was well maintained even when NGF was removed after 4 days, even though the morphological features of neuronal differentiation were rapidly lost on removal of NGF. The enhanced cAMP production in response to forskolin could be due to a synergistic interaction between forskolin and endogenously released agonists acting on G(s)-coupled receptors. However, responses to forskolin were not attenuated by antagonists of adenosine A2 receptors or pituitary adenylate cyclase-activating polypeptide (PACAP) receptors, suggesting that adenosine and PACAP were not involved. Adenylyl cyclases 3, 6 and 9 were the predominant isoforms expressed in PC12 cells, but we found no evidence for NGF-induced changes in expression levels of any of the 9 adenylyl cyclase isoforms, nor in the expression of G?(s). These findings highlight that NGF has a subtle influence on adenylyl cyclase activity in PC12 cells which may influence more than the neurite extension process classically associated with neuronal differentiation.

Neural network classifications and correlation analysis of EEG and MEG activity accompanying spontaneous reversals of the Necker cube.  

PubMed

It has recently been suggested that reentrant connections are essential in systems that process complex information [A. Damasio, H. Damasio, Cortical systems for the retrieval of concrete knowledge: the convergence zone framework, in: C. Koch, J.L. Davis (Eds.), Large Scale Neuronal Theories of the Brain, The MIT Press, Cambridge, 1995, pp. 61-74; G. Edelman, The Remembered Present, Basic Books, New York, 1989; M.I. Posner, M. Rothbart, Constructing neuronal theories of mind, in: C. Koch, J.L. Davis (Eds.), Large Scale Neuronal Theories of the Brain, The MIT Press, Cambridge, 1995, pp. 183-199; C. von der Malsburg, W. Schneider, A neuronal cocktail party processor, Biol. Cybem., 54 (1986) 29-40]. Reentry is not feedback, but parallel signalling in the time domain between spatially distributed maps, similar to a process of correlation between distributed systems. Accordingly, it was expected that during spontaneous reversals of the Necker cube, complex patterns of correlations between distributed systems would be present in the cortex. The present study included EEG (n=4) and MEG recordings (n=5). Two experimental questions were posed: (1) Can distributed cortical patterns present during perceptual reversals be classified differently using a generalised regression neural network (GRNN) compared to processing of a two-dimensional figure? (2) Does correlated cortical activity increase significantly during perception of a Necker cube reversal? One-second duration single trials of EEG and MEG data were analysed using the GRNN. Electrode/sensor pairings based on cortico-cortical connections were selected to assess correlated activity in each condition. The GRNN significantly classified single trials recorded during Necker cube reversals as different from single trials recorded during perception of a two-dimensional figure for both EEG and MEG. In addition, correlated cortical activity increased significantly in the Necker cube reversal condition for EEG and MEG compared to the perception of a non-reversing stimulus. Coherent MEG activity observed over occipital, parietal and temporal regions is believed to represent neural systems related to the perception of Necker cube reversals. PMID:9593980

Proteolytic activation of the essential parasitophorous vacuole cysteine protease SERA6 accompanies malaria parasite egress from its host erythrocyte.  

PubMed

The malaria parasite replicates within an intraerythrocytic parasitophorous vacuole (PV). The PV and host cell membranes eventually rupture, releasing merozoites in a process called egress. Certain inhibitors of serine and cysteine proteases block egress, indicating a crucial role for proteases. The Plasmodium falciparum genome encodes nine serine-repeat antigens (SERAs), each of which contains a central domain homologous to the papain-like (clan CA, family C1) protease family. SERA5 and SERA6 are indispensable in blood-stage parasites, but the function of neither is known. Here we show that SERA6 localizes to the PV where it is precisely cleaved just prior to egress by an essential serine protease called PfSUB1. Mutations that replace the predicted catalytic Cys of SERA6, or that block SERA6 processing by PfSUB1, could not be stably introduced into the parasite genomic sera6 locus, indicating that SERA6 is an essential enzyme and that processing is important for its function. We demonstrate that cleavage of SERA6 by PfSUB1 converts it to an active cysteine protease. Our observations reveal a proteolytic activation step in the malarial PV that may be required for release of the parasite from its host erythrocyte. PMID:22984267

Persistent At-Level Thermal Hyperalgesia and Tactile Allodynia Accompany Chronic Neuronal and Astrocyte Activation in Superficial Dorsal Horn following Mouse Cervical Contusion Spinal Cord Injury  

PubMed Central

In humans, sensory abnormalities, including neuropathic pain, often result from traumatic spinal cord injury (SCI). SCI can induce cellular changes in the CNS, termed central sensitization, that alter excitability of spinal cord neurons, including those in the dorsal horn involved in pain transmission. Persistently elevated levels of neuronal activity, glial activation, and glutamatergic transmission are thought to contribute to the hyperexcitability of these dorsal horn neurons, which can lead to maladaptive circuitry, aberrant pain processing and, ultimately, chronic neuropathic pain. Here we present a mouse model of SCI-induced neuropathic pain that exhibits a persistent pain phenotype accompanied by chronic neuronal hyperexcitability and glial activation in the spinal cord dorsal horn. We generated a unilateral cervical contusion injury at the C5 or C6 level of the adult mouse spinal cord. Following injury, an increase in the number of neurons expressing ?FosB (a marker of chronic neuronal activation), persistent astrocyte activation and proliferation (as measured by GFAP and Ki67 expression), and a decrease in the expression of the astrocyte glutamate transporter GLT1 are observed in the ipsilateral superficial dorsal horn of cervical spinal cord. These changes have previously been associated with neuronal hyperexcitability and may contribute to altered pain transmission and chronic neuropathic pain. In our model, they are accompanied by robust at-level hyperaglesia in the ipsilateral forepaw and allodynia in both forepaws that are evident within two weeks following injury and persist for at least six weeks. Furthermore, the pain phenotype occurs in the absence of alterations in forelimb grip strength, suggesting that it represents sensory and not motor abnormalities. Given the importance of transgenic mouse technology, this clinically-relevant model provides a resource that can be used to study the molecular mechanisms contributing to neuropathic pain following SCI and to identify potential therapeutic targets for the treatment of chronic pathological pain.

Mitotic Defects Lead to Pervasive Aneuploidy and Accompany Loss of RB1 Activity in Mouse LmnaDhe Dermal Fibroblasts  

PubMed Central

Background Lamin A (LMNA) is a component of the nuclear lamina and is mutated in several human diseases, including Emery-Dreifuss muscular dystrophy (EDMD; OMIM ID# 181350) and the premature aging syndrome Hutchinson-Gilford progeria syndrome (HGPS; OMIM ID# 176670). Cells from progeria patients exhibit cell cycle defects in both interphase and mitosis. Mouse models with loss of LMNA function have reduced Retinoblastoma protein (RB1) activity, leading to aberrant cell cycle control in interphase, but how mitosis is affected by LMNA is not well understood. Results We examined the cell cycle and structural phenotypes of cells from mice with the Lmna allele, Disheveled hair and ears (LmnaDhe). We found that dermal fibroblasts from heterozygous LmnaDhe (LmnaDhe/+) mice exhibit many phenotypes of human laminopathy cells. These include severe perturbations to the nuclear shape and lamina, increased DNA damage, and slow growth rates due to mitotic delay. Interestingly, LmnaDhe/+ fibroblasts also had reduced levels of hypophosphorylated RB1 and the non-SMC condensin II-subunit D3 (NCAP-D3), a mitosis specific centromere condensin subunit that depends on RB1 activity. Mitotic check point control by mitotic arrest deficient-like 1 (MAD2L1) also was perturbed in LmnaDhe/+ cells. LmnaDhe/+ fibroblasts were consistently aneuploid and had higher levels of micronuclei and anaphase bridges than normal fibroblasts, consistent with chromosome segregation defects. Conclusions These data indicate that RB1 may be a key regulator of cellular phenotype in laminopathy-related cells, and suggest that the effects of LMNA on RB1 include both interphase and mitotic cell cycle control.

Interactive Whiteboard Integration in Classrooms: Active Teachers Understanding about Their Training Process  

NASA Astrophysics Data System (ADS)

With the incorporation in education of Information and Communication Technologies (ICT), especially the Interactive Whiteboard (IWB), emerges the need for a proper teacher training process due to adequate the integration and the didactic use of this tool in the classroom. This article discusses the teachers' perception on the training process for ICT integration. Its main aim is to contribute to the unification of minimum criteria for effective ICT implementation in any training process for active teachers. This case study begins from the development of a training model called Eduticom which was putted into practice in 4 schools in Catalonia, Spain. Findings indicated different teachers' needs such as an appropriate infrastructure, a proper management and a flexible training model which essentially addresses methodological and didactic aspects of IWB uses in the classroom.

The effects of exergaming on physical activity among inactive children in a physical education classroom.  

PubMed

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. PMID:21541146

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.)

Moisture processes accompanying convective activity  

NASA Technical Reports Server (NTRS)

A moisture budget analysis was performed on data collected during the AVE 7 (May 2 to 3, 1978) and AVE-SESAME1 (April 10 to 11, 1979) experiments. Local rates-of-change of moisture were compared with average moisture divergence in the same time period. Results were presented as contoured plots in the horizontal and as vertical cross sections. These results were used to develop models of the distribution of moisture processes in the vicinity of convective areas in two layers representing lower and middle tropospheric conditions. Good correspondence was found between the residual term of the moisture budget and actual precipitation.

Dehydration induced loss of photosynthesis in Arabidopsis leaves during senescence is accompanied by the reversible enhancement in the activity of cell wall ?-glucosidase.  

PubMed

The physiology of loss of photosynthetic production of sugar and the consequent cellular sugar reprogramming during senescence of leaves experiencing environmental stress largely remains unclear. We have shown that leaf senescence in Arabidopsis thaliana causes a significant reduction in the rate of oxygen evolution and net photosynthetic rate (Pn). The decline in photosynthesis is further aggravated by dehydration. During dehydration, primary photochemical reaction of thylakoids and net photosynthesis decrease in parallel with the increase in water deficit. Senescence induced loss in photosynthesis is accompanied by a significant increase in the activity of cell wall hydrolyzing enzyme such as ?-glucosidase associated with cell wall catabolism. The activity of this enzyme is further enhanced when the senescing leaves experience dehydration stress. It is possible that both senescence and stress separately or in combination result in the loss in photosynthesis which could be a signal for an enhancement in the activity of ?-glucosidase that breaks down cell wall polysaccharides to sugar to sustain respiration for metabolic activities of plants experiencing stress. Thus dehydration response of cell wall hydrolases of senescing leaves is considered as plants' strategy to have cell wall polysaccharides as an alternative energy source for completion of energy requiring senescence process, stress survival and maintenance of recovery potential of energy deficit cells in the background of loss in photosynthesis. Withdrawal of stress (rehydration) distinctly exhibits recovery of photosynthesis and suppression of enzyme activity. Retention of the signaling for sugar reprogramming through breakdown of cell wall polysaccharides in the senescing leaves exposed to severe drought stress suggests that senescing leaves like mature ones possess potential for stress recovery. The precise mechanism of stress adaptation of senescing leaves is yet to be known. A significant accumulation of anthocyanin and flavonoids may be an indicator of stress adaptation of senescing leaves. In addition, stress induced enhancement of nonphotochemical quenching (NPQ), a stress protection provision in green plants, also suggests the potential of the leaves to develop adaptational mechanism to counter the dehydration stress.

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.

Effects of Animal-Assisted Activities with Guinea Pigs in the Primary School Classroom  

PubMed Central

This study investigated the effects of a classroom-based animal-assisted activities (AAA) program with guinea pigs on the social functioning of primary school children. We hypothesized that participants in the experimental condition (n = 64), compared with a waitlist control group (n = 64), would demonstrate improvements in social functioning following the program. Parents and teachers used the Social Skills Rating System (SSRS) to evaluate the social skills and problem behaviors of 128 participating children (age range = 4.8 to 12.7 years) before and after an 8-week period. Teachers also rated academic competence at both time points. Children who participated in the AAA program demonstrated significantly greater improvements in social functioning than their control group peers, as defined by greater increases in social skills (teacher SSRS) and decreases in problem behaviors (parent and teacher SSRS). There were no significant differences between the groups in academic competence. AAA participants demonstrated significant increases in social skills and decreases in problem behaviors from pre- to post-program on the teacher version of the SSRS. Control group participants did not show significant changes on these measures. These findings suggest that an AAA program with guinea pigs may be a feasible addition to the primary school classroom in order to improve social functioning. Further component analysis will be necessary to determine whether the animal is the active ingredient in AAA programs of this nature. PMID:24265514

The tetramethoxyflavone zapotin selectively activates protein kinase C epsilon, leading to its down-modulation accompanied by Bcl-2, c-Jun and c-Fos decrease  

PubMed Central

Zapotin, a tetramethoxyflavone, is a natural compound with a wide spectrum of activities in neoplastic cells. Protein kinase C epsilon (PKC?) has been shown to be oncogenic, with the ability to increase cell migration, invasion and survival of tumor cells. Here we report that zapotin inhibits cell proliferation. In wild-type HeLa cells with basal endogenous expression of PKC?, the IC50 was found to be 17.9 ± 1.6 ?M. In HeLa cells overexpressing doxycycline-inducible constitutively active PKC? (HeLaPKC?A/E), the IC50 was 7.6 ± 1.3 ?M, suggesting that PKC? enhances the anti-proliferative effect of zapotin. Moreover, we found that zapotin selectively activated PKC? in comparison with other PKC family members, but attenuated doxycycline-induced PKC? expression. As a result of zapotin treatment for 6, 12 and 24 h, the doxycycline-induced levels of the two differently phosphorylated PKC? forms (87 kDa and 95 kDa) were decreased. Migration assays revealed that increasing concentrations of zapotin (from 3.5 to 15 ?M) decreased migration of HeLaPKC?A/E cells. Furthermore, zapotin significantly increased the fraction of apoptotic cells in doxycycline-induced (HeLaPKC?A/E) cells after 24 h and decreased the levels of Bcl-2, c-Jun, c-Fos. This was accompanied by a degradation of PARP-1. In summary, activation of PKC? and down-modulation of the induced PKC? level by zapotin were associated with decreased migration and increased apoptosis. These observations are consistent with the previously reported chemopreventive and chemotherapeutic action of zapotin. PMID:22381066

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. PMID:24968196

Activities of X-ray binaries accompanied by a neutron star with weak magnetic field: Cir X-1, Aql X-1 and 4U 1608-52  

NASA Astrophysics Data System (ADS)

This paper is presented on X-ray activities of X-ray binaries accompanied by a neutron star with weak magnetic field. Neutron star low mass X-ray binaries (NS-LMXBs) have been well studied so far, but there are still unknown problems concerning activities of outbursts and X-ray spectral features. We can define the soft and hard states which show different spectra created from each disk structure. These states depend on the gas accretion rate causing viscosity change in the disk, whereas we have pointed out an importance of magnetic field in NS-LMXB for X-ray activities (Matsuoka & Asai 2013). Thus, we have obtained decay features occurred by a propeller effect for Aql X-1 and 4U1608-52, and thus, we have defined the propeller effect levels of these sources (Asai et al. 2013). A companion star of Cir X-1 is a star of B5~A0 type, but it has X-ray spectral feature similar to NS-LMXB as well as it produced type I X-ray bursts. A long history over 40 years of X-ray observations has provided that Cir X-1 X-ray intensities have many varieties from continuous variable fluxes with Z-type feature of NS-LMXB to recurrent outburst fluxes with Atoll-type feature on a time scale of years. Recent MAXI observations have revealed a strange sudden decay feature in some outbursts. It is difficult to explain this decay feature by the simple picture which causes by ordinary mechanisms known in NS-LMXB such as a state transition, a propeller effect and a brink due to disk irradiation (Powell et al. 2007). Therefore, we introduced new type of instability of the accretion disk in relation to stellar wind stripping effect (Asai et al. 2014) which may be common to a system consisting of a compact star and an ordinary massive star.

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.

Activity Settings and Daily Routines in Preschool Classrooms: Diverse Experiences in Early Learning Settings for Low-Income Children  

PubMed Central

This paper examines activity settings and daily classroom routines experienced by 3- and 4-year-old low-income children in public center-based preschool programs, private center-based programs, and family child care homes. Two daily routine profiles were identified using a time-sampling coding procedure: a High Free-Choice pattern in which children spent a majority of their day engaged in child-directed free-choice activity settings combined with relatively low amounts of teacher-directed activity, and a Structured-Balanced pattern in which children spent relatively equal proportions of their day engaged in child-directed free-choice activity settings and teacher-directed small- and whole-group activities. Daily routine profiles were associated with program type and curriculum use but not with measures of process quality. Children in Structured-Balanced classrooms had more opportunities to engage in language and literacy and math activities, whereas children in High Free-Choice classrooms had more opportunities for gross motor and fantasy play. Being in a Structured-Balanced classroom was associated with children’s language scores but profiles were not associated with measures of children’s math reasoning or socio-emotional behavior. Consideration of teachers’ structuring of daily routines represents a valuable way to understand nuances in the provision of learning experiences for young children in the context of current views about developmentally appropriate practice and school readiness.

The Electron Runaround: Understanding Electric Circuit Basics Through a Classroom Activity  

NASA Astrophysics Data System (ADS)

Several misconceptions abound among college students taking their first general physics course, and to some extent pre-engineering physics students, regarding the physics and applications of electric circuits. Analogies used in textbooks, such as those that liken an electric circuit to a piped closed loop of water driven by a water pump, do not completely resolve these misconceptions. Mazur and Knight,2 in particular, separately note that such misconceptions include the notion that electric current on either side of a light bulb in a circuit can be different. Other difficulties and confusions involve understanding why the current in a parallel circuit exceeds the current in a series circuit with the same components, and include the role of the battery (where students may assume wrongly that a dry cell battery is a fixed-current rather than a fixed-voltage device). A simple classroom activity that students can play as a game can resolve these misconceptions, providing an intellectual as well as a hands-on understanding. This paper describes the "Electron Runaround," first developed by the author to teach extremely bright 8-year-old home-schooled children the basics of electric circuits and subsequently altered (according to the required level of instruction) and used for various college physics courses.

Neuroblastoma accompanied by hyperaldosteronism  

PubMed Central

Background: Tumors known derived from kidneys which take place in secondary hyperaldosteronism etiology are juxtaglomerular cell tumor and Wilms’ tumor. Neuroblastoma presenting with hyperaldosteronism is rare. Case: A 15-month-old girl who had been having diarrhea and fever for 2 weeks presented with a 3 day history of bilious vomiting, metabolic acidosis and severe hypokalemia. She was referred to our hospital with the pre-diagnosis of unknown manifest hypertension etiology, diarrhea, and paralytic ileus after having therapy-resistant hypokalemia and severe resistant acidosis. On her examination after being admitted to our clinic, she was weak, unwell and lethargic with a blood pressure of 140/93 mmHg. Due to the hypertension and severe hypokalemia, the patient was considered to be hyperaldosteronism. Serum aldosterone level, plasma renin activity and cortisol level were elevated. Radiologic findings were compatible with neuroblastoma. The patient underwent an abdominal surgery and the mass excision. The histopathological examination was proved neuroblastoma. Conclusion: Hyperaldosteronism can be presented by unexpected atypical forms as in our patient PMID:25340174

Classroom interactions and science inquiry: A comparative study examining differential implementation of a science program in two middle school classrooms  

NASA Astrophysics Data System (ADS)

This dissertation explores two classroom communities during the implementation of a new environmental science curriculum. The classrooms are similar in that both are located in the same middle school and led by experienced classroom teachers. Despite these similarities, differences among learning outcomes are found in analyses of student pre- and post-science tests in the two rooms. Through videotape analysis of classroom interaction within parallel curricular activities, learning opportunities are contrasted in terms of the social and cognitive organization of science activities and the roles played by teachers, students, and scientists as manifested in their discourse. In one classroom, tasks flow between whole class discussions and small group work. Curricular activities are interwoven with transitions eased as goals are shared with students. Scientific concepts are connected through various activities and related to ideas outside of the classroom. Furthermore, the classroom community is united, established largely through the teacher's discourse patterns, such as deictics (specifically, inclusive personal pronouns). Moreover, the teacher emphasizes that she is learning alongside the students. In the other classroom, the focus of their science period is typically centered around whole class instruction or small group work depending on the particular lesson. This organization accompanied by a heavy use of directives leads to an implicit goal of completing the assigned task. Curricular activities are isolated, with an emphasis on following protocol instructions. Through discursive patterns, such as endearing address terms and exclusive pronouns, a dichotomy is created between the teacher and student. As the designated expert, this teacher imparts her knowledge of science to the students. Several implications emerge from this study. Although pre-packaged, curricular lessons appear identical on paper, the enacted curriculum differs, even in similar settings. Without doubt, science curricula can be useful in providing suggested guidelines and much needed materials for the classroom, but such curricula do not necessarily translate into student inquiry. As researchers and educators, we need to look beyond the curricula into the classrooms themselves. Indeed, this research has convinced me that a better understanding of classroom communities can be gleaned through the study of lesson organization and the classroom roles.

Construction and characterization of a mercury-independent MerR activator (MerRAC): transcriptional activation in the absence of Hg(II) is accompanied by DNA distortion.  

PubMed Central

The MeR regulatory protein of transposon Tn501 controls the expression of the mercury resistance (mer) genes in response to the concentration of mercuric ions. MerR is unique among prokaryotic regulatory proteins so far described in that it acts as a repressor [-Hg(II)] and an activator [+Hg(II)] of transcription of the mer genes, but binds to a single site on the DNA in both cases. This transcriptional activation process has been postulated to involve a protein-induced conformational change in the DNA that allows RNA polymerase more readily to form an open complex at the promoter. It has been shown [Frantz and O'Halloran (1990) Biochemistry, 29, 4747-4751] that activation of transcription by MerR in the presence of mercury is accompanied by hypersensitivity of the operator to chemical nucleases that are sensitive to local distortion in DNA structure. Here we describe specific mutations in MerR that allow the protein to stimulate transcription in the absence of the allosteric activator Hg(II). We demonstrate that the degree of activation caused by these mutants directly correlates with the degree of DNA distortion as measured by the hypersensitivity of MerR-DNA complexes to the nuclease Cu-5-phenyl-o-phenanthroline. These results support the model described above. Images PMID:8440234

A New Approach to Teaching Petrology: Active Learning in a Studio Classroom  

NASA Astrophysics Data System (ADS)

During the past 15 years it has become clear that the traditional lecture and lab approach to college science teaching leaves much to be desired. The traditional approach is instructor oriented and based on passive learning. In contrast, current studies show that most students learn best when actively engaged in the learning process. Inquiry based learning and open ended projects have been shown to especially enhance learning by promoting higher order thinking. Recognizing the need for change, however, does not mean the changes are simple. The task of overhauling a course, replacing traditional approaches with more student oriented activities, requires a great deal of time and effort. It also involves much uncertainty and risk. At UND we have been experimenting with alternative pedagogies for a number of years. Change has been incremental, but this year we made wholesale changes in our petrology class. We converted it from the standard three lecture and one lab format to two 3-hour studio sessions per week. The distinction between lab and lecture is gone. In fact, there really are no lectures. The instructor talks for no more than 15 or 20 minutes at a time. Students spend most of their time doing, not listening. We emphasize collaborative active learning projects, some quite short and others lengthy and involved, and use a wide variety of activities. To assess the class, we have an outside consultant and we carry out weekly assessments to measure (1) how students are reacting to the various pedagogical approaches, and (2) how much student learning is actually occurring. This allows us to make adjustments and fine tune as necessary. We could not have made such changes a few years ago, simply because of the amount of work involved to create and test the necessary classroom materials. Today, however, there are many resources available to the reform minded teacher, and the resource base continues to grow. We borrowed heavily from other instructors at other institutions. We mined the Journal of Geoscience Education for teaching and assessment strategies. We took many ideas for projects from the recent Teaching Petrology Workshop (July 2003, one of the On the Cutting Edge: Workshops for Geoscience Faculty, supported by the NAGT, DLESE and NSF/DUE). With more workshops and meetings devoted to teaching reform, and as geoscientists further develop their scholarship of teaching and learning, reforming our classes will become easier. The result will not only be better educated students, but also a greater retention of geoscience majors.

Classroom-based high-intensity interval activity improves off-task behaviour in primary school students.  

PubMed

This study examined the effects of an acute bout of brief, high-intensity interval exercise on off-task classroom behaviour in primary school students. A grade 4 class (n = 24) and a grade 2 class (n = 20) were exposed to either a no-activity break or an active break that consisted of "FUNtervals", a high-intensity interval protocol, on alternating days for 3 weeks. No-activity days consisted of a 10-min inactive break while FUNterval days consisted of a 4-min FUNterval completed within a 10-min break from regular class activities. Off-task behaviour was observed for 50 min after each no-activity/FUNterval break, with the amount of time students spent off-task (motor, passive, and verbal behaviour) being recorded. When comparing no-activity breaks with FUNtervals the grade 4 class demonstrated reductions in both passive (no activity = 29% ± 13% vs. FUNterval = 25% ± 13%, p < 0.05, effect size (ES) = 0.31) and motor (no activity = 31% ± 16% vs. FUNterval = 24% ± 13%, p < 0.01, ES = 0.48) off-task behaviour following FUNtervals. Similarly, in the grade 2 class, passive (no activity = 23% ± 14% vs. FUNterval = 14% ± 10%, p < 0.01, ES = 0.74), verbal (no activity = 8% ± 8% vs. FUNterval = 5% ± 5%, p < 0.05, ES = 0.45), and motor (no activity = 29% ± 17% vs. FUNterval = 14% ± 10%, p < 0.01, ES = 1.076) off-task behaviours were reduced following FUNtervals. In both classrooms the effects of physical activity were greatest in those students demonstrating the highest rates of off-task behaviour on no-activity days. These data demonstrate that very brief high-intensity bouts of exercise can improve off-task behaviour in grade 2 and 4 students, particularly in students with high rates of such behaviour.

Levo-tetrahydropalmatine attenuates the development and expression of methamphetamine-induced locomotor sensitization and the accompanying activation of ERK in the nucleus accumbens and caudate putamen in mice.  

PubMed

Levo-tetrahydropalmatine (l-THP) is an alkaloid purified from corydalis and has been used in many traditional Chinese herbal preparations for its analgesic, sedative, and hypnotic properties. Previous studies indicated that l-THP has modest antagonist activity against dopamine receptors and thus it might have potential therapeutic effects on drug addiction. However, whether and how l-THP contributes to methamphetamine (METH)-induced locomotor sensitization remains unclear. Therefore, the current study aims to examine the roles of l-THP in the development and expression of METH-induced locomotor sensitization as well as the accompanying extracellular-regulated kinase (ERK) activation in the nucleus accumbens (NAc), caudate putamen (CPu) and prefrontal cortex (PFc) in mice. We found that moderate doses of METH (0.5 and 2 mg/kg) induced hyper-locomotor activity in mice on all METH injection days whereas high dose of METH (5 mg/kg)-treated mice displayed only acute locomotor response to METH and severe stereotyped behaviors on the first day after drug injection. Interestingly, only 2 mg/kg dose of METH-induced locomotor sensitization which was accompanied by the activation of ERK1/2 in the NAc and CPu in mice. Although l-THP (5 and 10 mg/kg) per se did not induce obvious changes in locomotor activities in mice, its co-administration with METH could significantly attenuate acute METH-induced hyper-locomotor activity, the development and expression of METH-induced locomotor sensitization, and the accompanying ERK1/2 activation in the NAc and CPu. These results suggest that l-THP has potential therapeutic effect on METH-induced locomotor sensitization, and the underlying molecular mechanism might be related to its inhibitory effect on ERK1/2 phosphorylation in the NAc and CPu.

Altered Spontaneous Brain Activity in Patients with Parkinson's Disease Accompanied by Depressive Symptoms, as Revealed by Regional Homogeneity and Functional Connectivity in the Prefrontal-Limbic System  

PubMed Central

As patients with Parkinson’s disease (PD) are at high risk for comorbid depression, it is hypothesized that these two diseases are sharing common pathogenic pathways. Using regional homogeneity (ReHo) and functional connectivity approaches, we characterized human regional brain activity at resting state to examine specific brain networks in patients with PD and those with PD and depression (PDD). This study comprised 41 PD human patients and 25 normal human subjects. The patients completed the Hamilton Depression Rating Scale and were further divided into two groups: patients with depressive symptoms and non-depressed PD patients (nD-PD). Compared with the non-depressed patients, those with depressive symptoms exhibited significantly increased regional activity in the left middle frontal gyrus and right inferior frontal gyrus, and decreased ReHo in the left amygdala and bilateral lingual gyrus. Brain network connectivity analysis revealed decreased functional connectivity within the prefrontal-limbic system and increased functional connectivity in the prefrontal cortex and lingual gyrus in PDD compared with the nD-PD group. In summary, the findings showed regional brain activity alterations and disruption of the mood regulation network in PDD patients. The pathogenesis of PDD may be attributed to abnormal neural activity in multiple brain regions. PMID:24404185

Activation of human heat shock genes is accompanied by oligomerization, modification, and rapid translocation of heat shock transcription factor HSF1.  

PubMed Central

Transcriptional activity of heat shock (hsp) genes is controlled by a heat-activated, group-specific transcription factor(s) recognizing arrays of inverted repeats of the element NGAAN. To date genes for two human factors, HSF1 and HSF2, have been isolated. To define their properties as well as the changes they undergo during heat stress activation, we prepared polyclonal antibodies to these factors. Using these tools, we have shown that human HeLa cells constitutively synthesize HSF1, but we were unable to detect HSF2. In unstressed cells HSF1 is present mainly in complexes with an apparent molecular mass of about 200 kDa, unable to bind to DNA. Heat treatment induces a shift in the apparent molecular mass of HSF1 to about 700 kDa, concomitant with the acquisition of DNA-binding ability. Cross-linking experiments suggest that this change in complex size may reflect the trimerization of monomeric HSF1. Human HSF1 expressed in Xenopus oocytes does not bind DNA, but derepression of DNA-binding activity, as well as oligomerization of HSF1, occurs during heat treatment at the same temperature at which hsp gene expression is induced in this organism, suggesting that a conserved Xenopus protein(s) plays a role in this regulation. Inactive HSF1 resides in the cytoplasm of human cells; on activation it rapidly translocates to a soluble nuclear fraction, and shortly thereafter it becomes associated with the nuclear pellet. On heat shock, activatable HSF1, which might already have been posttranslationally modified in the unstressed cell, undergoes further modification. These different process provide multiple points of regulation of hsp gene expression. Images PMID:8455624

Circadian regulation of chloroplast transcription in Chlamydomonas is accompanied by little or no fluctuation in RPOD levels or core RNAP activity.  

PubMed

In Chlamydomonas growing under 24 h light-dark cycles, chloroplast transcription is under circadian clock control, and peaks early in the morning. The peak (but not trough) requires ongoing cytoplasmic translation, as it is sensitive to cycloheximide (CH). The chloroplast transcriptional apparatus in Chlamydomonas is simpler than in land plants, with only one type of RNA polymerase (RNAP, bacterial) and apparently only one sigma factor (RPOD). Core RNAP can be assayed in vitro with a non-sigma factor dependent template, and is sensitive to rifampicin. We developed a membrane-based assay for RNAP activity, and used it to determine that core activity is only weakly affected by pre-treating cells with CH. Moreover, core chloroplast RNAP activity was steady during a 24 h light-dark cycle. Levels of the sigma factor (RPOD) were examined using western blots, and found to fluctuate less than 25 % during light-dark cycles. These data indicate that circadian regulation of chloroplast transcription is distinct from regulation by sulfur availability, which involves significant changes in RPOD levels. The implications of this data for hypotheses that purport to explain the circadian control mechanism are discussed. PMID:23053955

Flipping the Classroom  

NASA Astrophysics Data System (ADS)

A recent trend in education is the "flipped" or "reversed" classroom. In this educational model, students view videos of the lectures as their homework and class time is used for activities and solving problems that might have been assigned as homework in a traditional classroom. Although far from an expert on flipping the classroom, I can see some merit in the idea. When students watch the videos at home, they can start and restart the lecture as often as they like. The lectures are also available for review before the exam. Class time can be used for higher-order questioning, experiments, and problem solving.

Plate Boundary Observatory Nucleus Education and Outreach: Bringing GPS and Data- Rich Activities Into College and Secondary Earth Science Classrooms  

NASA Astrophysics Data System (ADS)

Incorporating scientific data into the curriculum provides students with insight into elements of the scientific process such as developing questions and hypotheses, understanding how data are collected, evaluating data quality and limitations, and formulating conclusions based on scientific results (Manduca et al., 2003.) UNAVCO, a geodetic consortium and co-administrator of the Plate Boundary Observatory Nucleus project, seeks to increase public appreciation and understanding of Earth deformation processes and their societal relevance through education and outreach. To that end, we are developing place-based instructional materials for college and secondary Earth science classrooms in which GPS data are used to teach students about plate tectonics. To assess the needs of our users, we conducted interviews with college geoscience faculty from a variety of institution types and focus groups with secondary Earth science teachers to solicit feedback on the types of educational materials that they would likely use in their classrooms. We are engaging members of the scientific and educational communities to develop the materials and are catering the modules to accommodate diverse groups of learners and learning styles. In addition, we have completed and scheduled several professional development opportunities on the local and national levels for college and university faculty and secondary teachers and have created a new education and outreach website. Our education programs are being assessed by an external evaluator. We will present interview and focus group results, report on the status of our education programs, and discuss upcoming UNAVCO education activities.

Take-Home Challenges: Extending Discovery-Based Activities beyond the General Chemistry Classroom  

NASA Astrophysics Data System (ADS)

In an effort to more effectively integrate the experimental nature of chemistry into our students' experiences, we are developing and implementing discovery-based activities into both the laboratory and lecture components of general chemistry. Below we describe and provide an example of a "take-home challenge" intended to supplement the lecture component of the course. These take-home challenges involve the student in chemistry exploration outside of class and extend the context of content and experimentation into a nontraditional laboratory environment. Over 25 take-home challenges have been developed to date. Preliminary evaluation of the impact of the take-home challenges shows that students reporting themselves as receiving a B or C grade in the course find the challenges very useful in helping them gain a conceptual understanding of the phenomena addressed. Students earning an A grade report little or no impact on their learning. Prepared as one-page handouts, each take-home challenge begins with a scene-setting introduction followed by pertinent background information, a list of materials to be collected, and any appropriate safety precautions. The exploration component of the activity integrates leading questions with the procedural instructions to help guide the students through the discovery process and challenge them to stretch their understanding of the chemistry. After completing a take-home challenge activity, students submit written reports containing responses to the questions posed, observations of data collected, and their responses to the challenge. The accompanying sample take-home challenge activity is provided as a novel adaptation of the belch phenomenon that challenges students to experiment in order to explain the factors that account for the observed behavior. Persons interested in field testing the take-home challenges with their classes should contact the authors. Belch Bottle Challenge: What factors are responsible for the behavior of a "belch bottle"? Introductory Remarks. Have you ever belched? Belching is caused when there is an accumulation of gas in the digestive system. The "belch" occurs when the gas is released through the mouth. You can construct a "belch bottle" to imitate this action. Try this activity to find out how. Materials. 2 plastic soft-drink bottles of the same size one of the following sets of materials: potato; barrel of a Bic pen; tape (cellophane, electrical, or masking); 8-in. piece of wire, or 2 1-hole #3 stoppers; barrel of a Bic pen; tape (cellophane, electrical, or masking) water shallow tray or sink (optional) food color (optional) narrow-necked bottle made of glass (or other rigid material) Getting Ready. Cut one of the soft-drink bottles a few inches above the bottom to make a tall funnel as shown in Figure 1. Fill the second, uncut bottle half-full with water. If there is a hole in the side of the pen barrel, wrap tape around it. If 1-hole stoppers are available, slide one onto each end of the pen barrel and use this assembly to connect the cut funnel and the half-filled, uncut bottle. Alternatively, push the barrel all the way through a potato, leaving an approximately equal amount of pen barrel sticking out each side of the potato. If potato becomes lodged inside the pen barrel (that would restrict air or water flow), use a wire to push it out. Slide one end of the pen barrel into the mouth of the funnel all the way to the potato and gently screw the potato onto the thread of the funnel. Gently screw the other end of the potato onto the threads of the neck of the half-filled, uncut bottle. (See Fig. 2.) Your goal is to create an airtight seal between the funnel and the uncut soft-drink bottle. Procedure. Place the apparatus in a shallow tray or sink. Fill the funnel 3/4 full with water. (Colored water is easier to see.) Give the bottle a slight squeeze. Watch for several minutes. What do you observe? Explain your observations. Disconnect the bottle from the connector. Pour water out of the bottle until it is again only

Nursing-induced somatosensory cortex plasticity: temporally decoupled changes in neuronal receptive field properties are accompanied by modifications in activity-dependent protein expression.  

PubMed

This study is an attempt to gain insight into the malleability of representational maps in the primary somatosensory cortex in relation to the expression of proteins involved in inhibitory and excitatory neurotransmitter systems that contribute to maintain these maps in a dynamic state. Malleability of somatosensory maps is characterized by changes in the sizes of neuron receptive fields (RFs) affecting the representational grain and in the locations and submodalities of these RFs modifying the map extent. The concomitance of these alterations remains so far hypothetical. We used nursing as an evolving source of ethologically significant cutaneous stimulation. This cyclic behavior is particularly suited to investigating the time course of experience-dependent cortical changes. Electrophysiological maps of the ventrum skin were recorded twice in the same lactating rats between nursing initiation and several weeks after nursing. We found that reduction in RF size occurred earlier than map expansion. As nursing time declined, the map expansion was maintained longer than the RF sharpening. Based on this difference in time course, we compared the expression patterns of several activity-dependent proteins in relation to the RF plasticity. Western blot analysis showed an increase in glutamic acid decarboxylase expression that was concomitant with RF contraction. In contrast, NR2A subunit of NMDA and alpha calcium/calmodulin kinase type II were upregulated at times when map expansion was observed. We propose that inhibitory and excitatory plasticity mechanisms operating with different time courses may contribute to the temporal dissociation of nursing-induced RF reshaping and map expansion.

The impact of using a veterinary medicine activity book in the classroom on fifth- and sixth-grade students' depictions of veterinarians.  

PubMed

Efforts to develop a diverse, future veterinary workforce must start as early as elementary school, when children begin to form perceptions about careers. The objective of the current project was to determine the impact of the Veterinary Medicine Activity Book: Grade 5 on fifth- and sixth-grade students' depictions of veterinarians. The book was delivered as part of the curriculum in four classrooms. Students were asked to draw a veterinarian and describe the veterinarian's activities before and after being exposed to the book. Drawings were evaluated for the gender and race/ethnicity of the illustrated veterinarian, the description of the veterinarian's activity, and animals portrayed. Significant differences were detected within three of four classrooms. In one class, after exposure to the activity book, more students drew male veterinarians and veterinarians performing an activity specifically mentioned in the book. In a second class, more students drew large animals after exposure to the activity book. In a third class, after exposure to the activity book, more students drew large animals and veterinarians performing an activity specifically mentioned in the book. Results provide preliminary evidence that children's depictions of veterinarians can be altered through use of educational materials delivered in classrooms through teacher-led discussion or formal lesson plans.

Beyond the didactic classroom: educational models to encourage active student involvement in learning.  

PubMed

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. PMID:18483586

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

GeoMapApp Learning Activities: Grab-and-go inquiry-based geoscience activities that bring cutting-edge technology to the classroom  

NASA Astrophysics Data System (ADS)

NSF-funded GeoMapApp Learning Activities (http://serc.carleton.edu/geomapapp) provide self-contained learning opportunities that are centred around the principles of guided inquiry. The activities allow students to interact with and analyse research-quality geoscience data to explore and enhance student understanding of underlying geoscience content and concepts. Each activity offers ready-to-use step-by-step student instructions and answer sheets that can be downloaded from the web page. Also provided are annotated teacher versions of the worksheets that include teaching tips, additional content and suggestions for further work. Downloadable pre- and post- quizzes tied to each activity help educators gauge the learning progression of their students. Short multimedia tutorials and details on content alignment with state and national teaching standards round out the package of material that comprises each "grab-and-go" activity. GeoMapApp Learning Activities expose students to content and concepts typically found at the community college, high school and introductory undergraduate levels. The activities are based upon GeoMapApp (http://www.geomapapp.org), a free, easy-to-use map-based data exploration and visualisation tool that allows students to access a wide range of geoscience data sets in a virtual lab-like environment. Activities that have so far been created under this project include student exploration of seafloor spreading rates, a study of mass wasting as revealed through geomorphological evidence, and an analysis of plate motion and hotspot traces. The step-by-step instructions and guided inquiry approach lead students through each activity, thus reducing the need for teacher intervention whilst also boosting the time that students can spend on productive exploration and learning. The activities can be used, for example, in a classroom lab with the educator present and as self-paced assignments in an out-of-class setting. GeoMapApp Learning Activities are hosted on the SERC-Carleton web site.

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.

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.

Bridging the gap between what is praised and what is practiced: Supporting the work of change as anatomy and physiology instructors introduce active learning into their undergraduate classroom  

NASA Astrophysics Data System (ADS)

When college Anatomy & Physiology instructors begin using active learning in their classrooms, what do they experience? How do their beliefs about teaching and learning change? What obstacles do they encounter and how do they respond? How do their responses influence future decisions regarding the use of active learning? This study documented the experiences of seven instructors from diverse types of institutions as they began using active learning in their classrooms. Conceptual change and social cognitive motivation theory provided guidance for the 15-month project. A classroom-situated professional development framework that included goal setting, planning and doing active learning and formative assessment, and reflecting on experiences was used. Multiple data sources (verbatim transcripts from emergent and semi-structured interviews, observation notes, surveys, written correspondence, instructional materials, and student surveys) and research methods allowed rigorous exploration of the research questions. A number of important findings emerged from the study. Data indicated that instructors struggled with a lack of instructional, pedagogical and clinical content knowledge, student resistance, personal and professional risk-taking issues, and widely shifting attitudes toward active learning. Data also suggested a developmental progression in beliefs about teaching and learning as instructors implemented active learning, and the progression shared similarities with reports of preservice teacher development documented in the learning-to-teach literature. Initially, instructors' beliefs shifted from knowledge transmission and intuitive theories to constructivist theories; however there was marked variation in the intelligibility, status, and endurance of the new beliefs. Data also allowed identification of two distinct conceptual change experiences. Analysis of instructor beliefs within and between the change groups strongly suggested that causal attribution constructs either facilitated or precluded belief development, conceptual change, and a more encompassing and sophisticated definition of active learning, and supported the emergence of an Attribution-Based Conceptual Change Schematic. The findings have significant implications for both change-desiring instructors and faculty development staff. The findings allow faculty to familiarize themselves with the obstacles and response patterns that may shape their own change experiences and allow development staff to design empirically grounded learning opportunities that may facilitate the development of beliefs about teaching and learning and promote faculty conceptual change.

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.

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

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.

The role of authentic astronomy in the classroom: does participating in authentic astronomy activities increase knowledge and improve attitude towards science?  

NASA Astrophysics Data System (ADS)

This paper examines the impact of authentic science activities on student knowledge and attitudes. It uses optical astronomy as a core research theme. Modern, relatively cheap automated telescopes and imaging software has made transient object searches a valuable addition to research based searches conducted by professional astronomers. It is an exciting field of modern research where discoveries can have real life implications, such as discovering potentially hazardous near Earth asteroids. This has provided an opportunity to use transient object searches as a tool for authentic science in the classroom. My research followed the attitude of students aged eleven to seventeen in Australian schools, as they use research grade telescopes to study known asteroids and search for ones yet to be discovered.

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.

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

Mechanical Surface Waves Accompany Action Potential Propagation  

E-print Network

Many studies have shown that a mechanical displacement of the axonal membrane accompanies the electrical pulse defining the Action Potential (AP). Despite a large and diverse body of experimental evidence, there is no theoretical consensus either for the physical basis of this mechanical wave nor its interdependence with the electrical signal. In this manuscript we present a model for these mechanical displacements as arising from the driving of surface wave modes in which potential energy is stored in elastic properties of the neuronal membrane and cytoskeleton while kinetic energy is carried by the axoplasmic fluid. In our model these surface waves are driven by the traveling wave of electrical depolarization that characterizes the AP, altering the compressive electrostatic forces across the membrane as it passes. This driving leads to co-propagating mechanical displacements, which we term Action Waves (AWs). Our model for these AWs allows us to predict, in terms of elastic constants, axon radius and axoplasmic density and viscosity, the shape of the AW that should accompany any traveling wave of voltage, including the AP predicted by the Hodgkin and Huxley (HH) equations. We show that our model makes predictions that are in agreement with results in experimental systems including the garfish olfactory nerve and the squid giant axon. We expect our model to serve as a framework for understanding the physical origins and possible functional roles of these AWs in neurobiology.

Interactive Learning Activities for the Middle School Classroom to Promote Healthy Energy Balance and Decrease Diabetes Risk in the HEALTHY Primary Prevention Trial  

PubMed Central

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 onsite 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.

Surface Waves Accompany Action Potential Propagation  

E-print Network

In parallel with a long history of inquiry into action potential (AP) propagation, many studies have shown that a mechanical displacement of the axonal membrane accompanies the well characterized electrical pulse. Despite a large and diverse body of experimental evidence, there is no theoretical consensus either for the physical basis for this mechanical wave nor its interdependence with the electrical signal. In this manuscript we present a model for these mechanical displacements as arising from the driving of surface wave modes in which potential energy is stored in elastic properties of the neuronal membrane and cytoskeleton while kinetic energy is stored in the movement of the axoplasmic fluid. In our model these surface waves are driven by the traveling wave of electrical depolarization that characterizes the AP, which alter the compressive electrostatic forces across the membrane as it passes. Our model for these co-propagating mechanical displacements, which we term Action Waves (AWs) allows us to pre...

Sacral Perineural Cyst Accompanying Disc Herniation  

PubMed Central

Although most of sacral perineural cysts are asymptomatic, some may produce symptoms. Specific radicular pain may be due to distortion, compression, or stretching of nerve root by a space occupying cyst. We report a rare case of S1 radiculopathy caused by sacral perineural cyst accompanying disc herniation. The patient underwent a microscopic discectomy at L5-S1 level. However, the patient's symptoms did not improved. The hypesthesia persisted, as did the right leg pain. Cyst-subarachnoid shunt was set to decompress nerve root and to equalize the cerebrospinal fluid pressure between the cephalad thecal sac and cyst. Immediately after surgery, the patient had no leg pain. After 6 months, the patient still remained free of leg pain. PMID:19352483

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.

Looking for attributes of powerful teaching for numeracy in tasmanian K-7 classrooms  

NASA Astrophysics Data System (ADS)

This paper reports on the development and use of a classroom observation reflection tool designed to measure the extent to which pedagogies acknowledged in the literature as contributing to effective teaching of mathematics for numeracy are present in classrooms. The observation schedule was used in conjunction with a record of classroom activity to examine numeracy pedagogies in a sample of Tasmanian classrooms from Kindergarten to Year 7. Low levels of intellectual challenge in highly socially supportive classrooms were typical.

Extinction of Oct-3/4 gene expression in embryonal carcinoma [times] fibroblast somatic cell hybrids is accompanied by changes in the methylation status, chromatin structure, and transcriptional activity of the Oct-3/4 upstream region  

SciTech Connect

The OCT-3/4 gene provides an excellent model system with which to study the extinction phenomenon in somatic cell hybrids. The molecular mechanism that underlies the extinction of a tissue-specific transcription factor in somatic cell hybrides is evaluated and compared with its down-regulation in retinoic acid treated embryonal carcinoma cells. This study draws a connection between the shutdown of OCT-3/4 expression in retinoic acid (RA)-differentiated embryonal carcinoma (EC) cells and its extinction in hybrid cells. This repression of OCT-3/4 expression is achieved through changes in the methylation status, chromatin structure, and transcriptional activity of the OCT-3/4 upstream regulatory region. 59 refs.

[Pharmacotherapy of osteoporosis accompanied by lifestyle-related diseases].  

PubMed

Lifestyle-related diseases, such as diabetes mellitus, hypertension and dyslipidemias, are often accompanied by osteoporosis. Treatment of osteoporosis in such cases is essentially the same as that for primary osteoporosis, but it is important to be aware of the interference between osteoporosis treatment and the drugs used for the lifestyle-related diseases. Raloxifene, bisphosphonates and activated vitamin D are commonly used for treatment of osteoporosis, and they are reported to have a positive effect on atherosclerosis. Beta-blocker use, particularly selective beta-blocker, is associated with reduced fracture risk. Statin is also reported to stimulate bone formation via bone morphogenetic protein-2 expression, but their clinical utility has not yet been confirmed. One class of antidiabetic drugs, thiazolidinediones, causes bone loss and further increases fracture risk, placing thiazolidinediones in the category of drugs causing secondary osteoporosis.
